That is, the upper sponge 31 is above the screen 23 and the lower sponge 41 is below the screen 23 . The plurality of upper sponges 31 and lower sponges 41 are arranged at positions facing each other vertically.

In FIG. 4, an upper plate 33 having a plurality of upper through-holes 32 is arranged at the lower end of the upper holding means 30 . Each upper through-hole 32 is formed with a truncated conical protrusion 34 that protrudes upward from the upper surface 33 a of the upper plate 33 . An upper opening 34 a of the upper through-hole 32 is opened on the upper surface of the protrusion 34 . Thus, the upper through hole 32 vertically penetrates the upper plate 33 from the lower surface 33b of the upper plate 33 to the upper opening 34a of the protrusion 34 . The upper sponge 31 is attached to the lower end of the upper holding means 30 so that the upper surface of the upper sponge 31 is in contact with the lower surface 33 b of the upper plate 33 . As shown in FIG. 5 , in the upper plate 33 , the plurality of upper through holes 32 are formed within a region overlapping the upper sponge 31 in plan view.

In FIG. 4 , an upper cover 36 that surrounds an upper space 35 above the upper plate 33 is arranged above the upper plate 33 . An upper cover opening 36 a (first opening) is formed in a part of the side surface of the upper cover 36 . One end of an upper suction pipe 37 is connected to the upper cover opening 36a. Thus, the upper cover 36 seals the upper space 35 . In FIG. 3, an upper suction device 38 is connected to the other end of the upper suction pipe 37 . When the upper suction device 38 is operated, the upper space 35 of the upper holding means 30 is vacuum-sucked through the upper suction pipe 37 by the upper suction device 38 .

Thus, the upper holding means 30 provided in the dewatering section 7 covers the upper plate 33 in which a plurality of upper through-holes 32 penetrating vertically and the upper surface 33a of the upper plate 33 are covered. It has an upper cover 36 with an opening (upper cover opening 36a) and holds the upper sponge 31 from above. The upper cover 36 allows water coming flying from the papermaking unit 6 or the like and water discharged from the side surfaces of the upper sponge 31 and the lower sponge 41 during press dehydration to pass from the outside of the upper cover 36 to the upper sponge 31. It has a function to prevent inflow. As a result, moisture can be efficiently removed from the raw seaweed 24 in the dehydrating section 7 .

In FIG. 4, a lower plate 43 having a plurality of lower through-holes 42 is arranged at the upper end of the lower holding means 40 . The lower through hole 42 penetrates the lower plate 43 vertically from the upper surface 43a of the lower plate 43 to the lower surface 43b. A reinforcing member 44 is installed below the lower plate 43 to extend in the arrangement direction and support the lower plate 43 from below to prevent deformation of the lower plate 43 . A plurality of reinforcing member through-holes 44 a are formed in the lower end portion of the reinforcing member 44 . The lower sponge 41 is attached to the upper end of the lower holding means 40 so that the lower surface of the lower sponge 41 is in contact with the upper surface 43 a of the lower plate 43 . In the lower plate 43 , the plurality of lower through holes 42 are formed within a region overlapping the lower sponge 41 in plan view.

A lower cover 46 that surrounds a lower space 45 below the lower plate 43 is arranged below the lower plate 43 . A lower cover opening 46 a (second opening) is formed in a portion of the lower surface of the lower cover 46 . One end of a lower suction pipe 47 is connected to the lower cover opening 46a. Thus, the lower cover 46 seals the lower space 45 . In FIG. 3, a lower suction device 48 is connected to the other end of the lower suction tube 47 . When the lower suction device 48 is operated, the lower space 45 of the lower holding means 40 is vacuum-sucked through the lower suction pipe 47 by the lower suction device 48 .

Thus, the lower holding means 40 provided in the dewatering section 7 covers the lower plate 43 in which a plurality of lower through-holes 42 penetrating vertically and the lower surface 43b of the lower plate 43 are covered. It has a lower cover 46 with an opening (lower cover opening 46a) and holds the lower sponge 41 from below. In the lower cover 46, moisture flying from the papermaking unit 6 or the like and moisture discharged from the side surfaces of the upper sponge 31 and the lower sponge 41 during press dehydration are allowed to pass from the outside of the lower cover 46 to the lower sponge 41. It has a function to prevent inflow. As a result, moisture can be efficiently removed from the raw seaweed 24 in the dehydrating section 7 .

In FIG. 3, the dehydrating section 7 includes a press mechanism 39 that moves the upper holding means 30 up and down (arrow g). The height position of the lower holding means 40 is fixed. A press mechanism 39 removes moisture from the raw laver 24 (press dehydration) by lowering the upper holding means 30 and pressing the upper sponge 31 and the lower sponge 41 against the upper and lower sides of the screen 23 in which the raw laver 24 is made. . In this manner, the press mechanism 39 is an elevating means for vertically elevating the upper holding means 30 .

The elevating means may elevate the lower holding means 40 with respect to the upper holding means 30 whose height position is fixed, or may elevate both the upper holding means 30 and the lower holding means 40 . That is, before the lifting means, at least one of the upper holding means 30 and the lower holding means 40 is moved up and down, and the raw seaweed 24 made into the screen 23 by the upper sponge 31 and the lower sponge 41 is press-dewatered. If it is

In FIG. 4, the upper holding means 30 is lowered by the press mechanism 39, the upper sponge 31 and the lower sponge 41 are pressed against the screen 23 in which the raw seaweed 24 is made, and the upper sponge 31 and the lower sponge 41 are compressed and deformed. It shows a state in which moisture is being removed. Moisture absorbed by the upper sponge 31 from the raw seaweed 24 is discharged to the upper space 35 through the upper through-holes 32 . The moisture discharged to the upper space 35 is vacuum-sucked by the upper suction device 38 through the upper cover opening 36a.

Also, water absorbed by the lower sponge 41 from the raw seaweed 24 is discharged into the lower space 45 through the lower through-holes 42 and the reinforcing member through-holes 44a. The moisture discharged into the lower space 45 is vacuum-sucked by the lower suction device 48 through the lower cover opening 46a. In this manner, the water content of the raw seaweed 24 can be efficiently removed by performing vacuum suction with the upper suction device 38 and the lower suction device 48 during press dehydration.

After the press dehydration, the upper holding means 30 is lifted by the press mechanism 39 and the compression deformation of the upper sponge 31 and the lower sponge 41 is recovered. It is absorbed by the lower sponge 41 . During this time, vacuum suction is performed by the upper suction device 38 and the lower suction device 48, so that the moisture remaining in the upper space 35 and the lower space 45 can be prevented from flowing back to the upper sponge 31 and the lower sponge 41.例文帳に追加

Thus, the upper suction device 38 is a first suction means that vacuum-sucks moisture discharged from the upper through hole 32 through the first opening (upper cover opening 36a). The lower suction unit 48 is a second suction unit that vacuum-sucks moisture discharged from the lower through-hole 42 through the second opening (lower cover opening 46a). The dewatering section 7 may be configured to perform vacuum suction from the upper cover opening 36a and the lower cover opening 46a by a common suction machine (for example, the upper suction machine 38). That is, the first suction means and the second suction means may be common.

FIG. 6 shows an enlarged cross-sectional view of the vicinity of the upper cover opening 36a of the upper holding means 30 which is being lifted after press dehydration. Residual water W remains on the upper surface 33a of the upper plate 33, which was not vacuum-sucked by the upper suction machine 38 during press dehydration. Even in such a state, since the upper opening 34a of the upper through-hole 32 is formed at a position higher than the upper surface 33a of the upper plate 33 by the projection 34, the residual water W flows back to the upper sponge 31 through the upper through-hole 32. can be prevented. The residual water W is vacuum-sucked from the upper cover opening 36a by the upper sucker 38 until the next press dehydration. Even when the upper cover opening 36a is not vacuum-sucked, the projection 34 can prevent the residual water W from flowing back into the upper sponge 31. As shown in FIG.

As described above, the seaweed manufacturing apparatus 1 according to the present embodiment is configured so that the raw seaweed produced in the screen 23 is transported by the conveying means (the screen holder conveying means 2), the screen holder 5 holding the screen 23. It includes a dewatering section 7 for removing water from 24 .

The dewatering section 7 has an upper sponge 31 above the screen 23 and an upper plate 33 formed with a plurality of upper through-holes 32 penetrating vertically, and an upper holding means for holding the upper sponge 31 from above. 30, a lower sponge 41 below the screen 23, a lower plate 43 formed with a plurality of vertically penetrating lower through holes 42, a lower holding means 40 for holding the lower sponge 41 from below, and an upper A lifting means (pressing mechanism 39) for vertically lifting at least one of the holding means 30 and the lower holding means 40 is provided. The upper holding means 30 includes an upper cover 36 that covers the upper surface of the upper plate 33 and has a first opening (upper cover opening 36a) formed in a part thereof.

This prevents the water removed from the raw seaweed 24 in the dehydrating section 7 from flowing back to the upper sponge 31, so that the water can be removed from the raw seaweed 24 efficiently. The upper holding means 30 of the dewatering section 7 described above has a structure in which the upper plate 33 holding a plurality of upper sponges 31 shares one upper space 35 . The upper cover 36 may be provided with upper spaces 35 divided into halves, and an upper cover opening 36 a may be formed in each of the upper spaces 35 . Similarly, the lower holding means 40 may have a structure in which a lower space 45 is formed for each lower sponge 41 .

Next, with reference to FIG. 7, a second example of the dewatering unit provided in the laver manufacturing apparatus 1 of the present embodiment will be described. Hereinafter, the dehydrating section 7 shown in FIGS. 3 to 6 will be referred to as "first dehydrating section", and the second embodiment of the dehydrating section will be referred to as "second dehydrating section 50". In FIG. 7 , the second dehydrating section 50 includes an upper holding means 60 arranged above the screen holder 5 and a lower holding means 40 arranged below the screen holder 5 . The lower holding means 40 of the second dehydrating section 50 is the same as the lower holding means 40 of the first dehydrating section, and detailed description thereof will be omitted.

In FIG. 7, a plurality of upper sponges 61 are held side by side in the arrangement direction at the lower end of the upper holding means 60 . An upper plate 63 having a plurality of upper through holes 62 is arranged at the lower end of the upper holding means 60 . Each upper through-hole 62 is formed with a truncated conical protrusion 64 that protrudes upward from the upper surface 63 a of the upper plate 63 . An upper opening 64 a of the upper through-hole 62 is opened on the upper surface of the protrusion 64 . The upper sponge 61 is attached to the lower end of the upper holding means 60 so that the upper surface of the upper sponge 61 is in contact with the lower surface 63b of the upper plate 63. As shown in FIG. In the upper plate 63 , the plurality of upper through-holes 62 are formed within a region overlapping the upper sponge 61 in plan view.

A gutter 65 for collecting water discharged from the upper through-hole 62 and discharging it to the outside of the upper holding means 60 is arranged on one side portion of the upper holding means 60 in the conveying direction. A wall 66 which is higher than the upper surface 63a of the upper plate 63 and prevents moisture from leaking out of the upper holding means 60 is formed on the side opposite to the gutter 65 of the upper holding means 60. As shown in FIG. An upper surface 63a of the upper plate 63 is inclined so as to be lowered from the wall 66 side toward the gutter 65 side. As a result, water discharged from the upper through-holes 62 during press dehydration flows into the gutter 65 along the slope of the upper surface 63 a of the upper plate 63 . Thus, the upper surface 63 a of the upper plate 63 of the second dehydrator 50 is inclined in the direction in which the moisture discharged from the upper through-holes 62 is discharged from the upper plate 63 .

In FIG. 7, the lowest opening height position H1 among the plurality of upper openings 64a is higher than the highest upper surface height position H2 among the upper surface 63a of the upper plate 63. As shown in FIG. As a result, water discharged from the upper through-holes 62 during press dehydration can be prevented from flowing back to the upper sponge 61 through the upper through-holes 62 after press dehydration.

Note that the upper plate 63 is not limited to a shape in which the upper surface 63a is inclined in one direction. For example, the upper plate 63 has a mountain shape that is inclined in two directions so that the center in the conveying direction is high and the both side ends are low. The water discharged from the upper through-holes 62 during press dehydration may be drained along two slopes to the troughs 65 on both sides. That is, the upper surface 63a of the upper plate 63 may be inclined in a plurality of directions, and the upper holding means 60 may include a plurality of grooves 65 for discharging water at positions where water is discharged from the upper plate 63. FIG.

In addition, the upper surface 63 a of the upper plate 33 of the upper holding means 30 provided in the first dehydrating section (dehydrating section 7 ) is similar to the second dehydrating section 50 in that moisture discharged from the upper through holes 32 is discharged from the upper plate 33 (in a direction in which the side of the upper cover opening 36a is lowered). As a result, moisture can be more efficiently removed from the raw seaweed 24 that has been made into a screen 23. - 特許庁

Furthermore, the laver manufacturing apparatus 1 described above has a configuration in which one dewatering unit 7 is provided in the upper conveying path 2U, but the laver manufacturing apparatus 1 has a plurality (for example, two) in the conveying direction of the upper conveying path 2U. A dehydrating unit 7 may be provided, and the water content of the raw seaweed 24 may be removed while sequentially conveying the screen holders 5 to a plurality of dehydrating units 7 . When a plurality of dewatering units 7 are provided, even if two first dewatering units (dewatering units 7) are arranged side by side, or two second dewatering units 50 are arranged side by side, the second dewatering unit is provided on the paper making unit 6 side. By arranging the section 50, the first dewatering section may be arranged on the drying chamber 10 side. When two first dehydrating units are arranged side by side, the first dehydrating unit on the paper making unit 6 side has a weaker vacuum suction force, and the first dehydrating unit on the drying chamber 10 side has a stronger vacuum suction force. may As a result, the moisture can be efficiently removed while preventing the raw seaweed 24 from losing its shape.
