Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a continuous conveyance and processing device using a conveyor having a V-shaped hole, which cools and dehumidifies objects to be treated during conveyance. This relates to items that undergo thermal treatment such as

(Prior art) Air blast type continuous heat treatment equipment, which has been conventionally used to perform thermal treatment such as cooling and dehumidifying the workpiece while it is being transported, places the workpiece on a flat conveyor. The conveyor was then passed through a tunnel, and the objects were processed by circulating cold air or the like inside the tunnel. In other words, in a continuous conveyance and cooling system that punches holes in a steel belt conveyor, blows cold air from above the object placed on the belt conveyor, and draws cold air from below the belt conveyor, the object to be cooled is When the amount of air increases, the rate at which the object to be cooled covers the punched holes increases, resulting in the disadvantage that the amount of air necessary for cooling cannot be secured. In addition, when using a net conveyor instead of the steel strip belt with punched holes described above, the opening area is too large and the opening surface is flat, so if the amount of the object to be cooled on the net conveyor changes, the air volume will increase or decrease. Also, the cooling effect was unstable due to changes in the bypass factor due to the occurrence of areas where the air flows easily and areas where it does not flow easily. In addition, in the case of nets, there was a drawback that it was difficult to clean out the bacteria that grew in the residual water that collected in the creases.

For this reason, we used a corrugated punching plate to reduce the actual contact area with the workpiece to improve heat treatment efficiency, and by improving ventilation, we reduced the adhesion of debris etc. to the punching plate. There are also known conveyors that
68711), the punching plate is not structured to be easily attached and detached for convenient cleaning.

In addition, when specifically cooling the object to be processed,
There is also no known device equipped with a cooling power adding means having a simple configuration in order to increase the cooling rate as necessary.

(Problems to be Solved by the Invention) The present invention is intended to solve the various problems mentioned above.

[Structure of the invention]

(Means for Solving the Problems) A continuous conveyance and processing apparatus using a perforated corrugated conveyor according to the present invention has the following configuration in order to solve the above problems.

The above-mentioned V of the wave-shaped conveyor connects a large number of V-shaped plates having a large number of holes and continuously conveys them in an endless manner.
A member formed integrally with the side plate of the shape plate is removably fixed to each link plate of the conveyor using a fixing device.

In order to process the objects to be processed, a circulating ventilation passage is provided to form an atmosphere that generates ventilation in a cross section perpendicular to the direction of movement of the conveyor, and a sloping bottom is provided between the upper conveyor part and the lower conveyor part. A wall was installed to form part of the circulation ventilation path, and a heat exchanger and water nozzle were also installed above the upper conveyor section.

(Function) By removably fixing the member integrally formed with the side plate of each V-shaped plate of the corrugated conveyor to each chain plate of the conveyor using a fixing tool, cleaning, repair and inspection of the conveyor, etc. are facilitated. Sprinkling water from the water nozzle forms a water film on the object to be cooled, so the cooling power from the evaporation of the water film can increase the cooling rate. Sprinkled water droplets are separated by the provided inclined bottom wall.

(Example) In FIGS. 1 and 2, 2 is a V-shaped plate having a large number of holes 3, a recess 5 in the center, and flanges 4 at both ends. Chain conveyor 1 is continuously fixed to chain 6 by the method described below.
The roller 7 of the link chain 6 forms a chain gear 8
The chain conveyor 1 is continuously conveyed in an endless manner. 9 is a driven chain gear;
The pitch of one V-shaped plate 2 is made to match the pitch of the chain gear 8. The link chain 6 and its relationship to the V-shaped plate 2 will be explained with reference to FIGS. 3 to 6.

Side plates 10 slightly inclined inward are fixed to both end faces of each V-shaped plate 2, and have a gap 11 between them and the recess 5. A vertical member 12 is integrally provided on the side plate 10, and a horizontal member 13 is further integrally provided with this vertical member 12. A mounting plate portion 15 is formed integrally with the link plate 14 of the link chain 6 and at right angles thereto, and the mounting plate portion 15 and the horizontal member 13
and the bolt 16 and nut 1 through the spacer 18.
7, and the V-shaped plate 2 is detachably fixed to the link chain 6. The recess 5 of the V-shaped plate 2 is smoothly rounded, and the flanges 4 at both ends are also smooth and horizontal. Note that this collar 4 may be oriented slightly upward or downward. Further, the numerous holes 3 provided in the V-shaped plate 2 are shaped to allow wind and water droplets to pass through them very easily.

The chain conveyor 1 having the V-shaped plate 2 connected to the link chain 6 as described above moves within the cooling passage as shown in FIGS. 7 to 9. Both side walls 1
9, 19, heat exchanger 21 for ceiling cooling, bottom wall 2
Cold air is sent from above in the direction of arrow 23 to the object to be cooled 31 placed on the chain conveyor 1 which moves in the direction of arrow 20 in the cooling passage 24 consisting of two parts, and the object to be cooled 31 and the V-shaped plate are Go through 2. Such ventilation within a cross section perpendicular to the direction of movement of the conveyor is achieved by communicating the upper and lower sides of the cooling passage 24 through a wind tunnel 26 having a blower 25. In this embodiment, two blowers 25 are provided in each wind tunnel 26. With the above configuration, arrows 27→28→23→29
A circulation ventilation path consisting of →30→27 is formed.
The cold air cooled by the cooling heat exchanger 21 becomes supersaturated (humid) cold air by the spray from the water nozzle 32 and is sent to the object 31 to be cooled, and the V-shaped plate 2
After the water droplets are separated by the inclined bottom wall 22 passing through the holes 3, they are redirected as shown by the arrow 29 and sent to the blower 25 for recirculation. V of V-shaped plate 2
The shaped surface prevents the object to be cooled 31 from blocking the hole 3,
Ventilation cooling occurs extremely smoothly.

Further, the water spray nozzle 32 is used to spray water in a mist form from the upper surface of the object to be cooled 31 to form a water film on the object to be cooled 31, and to accelerate the cooling rate by the cooling power generated by the evaporation of the water film. The water film also has the effect of suppressing loss of the object 31 to be cooled. In the chain conveyor 1, the rollers 7 are attached to both side walls 1 of the cooling passage 24.
Rails 39 provided at the top and bottom of the inner surfaces of 9 and 19
It is transferred by rolling on the top.

〔Effect of the invention〕

Because it is a corrugated conveyor, it not only allows for a higher heat treatment air volume than conventional flat conveyors, but also allows the member integrated with the side plate of each V-shaped plate of the conveyor to be attached to and detached from each chain plate of the conveyor using a fixing device. Since it can be fixed, the conveyor can be easily cleaned, repaired and inspected, etc.

In addition, since a water film is formed on the object to be cooled by sprinkling water from the water nozzle, the cooling power increases due to the evaporation of the water film, increasing the cooling rate and increasing the circulation ventilation path in the processing equipment. Sprinkled water droplets can be separated by the inclined bottom wall provided in the section.
