Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for taking out the contents of a tank, such as thawed fish, and more specifically, for example, a device for taking out and removing thawed fish from a tank in a rapid thawing machine. The present invention relates to a device for removing contents from a tank, which can be used for discharging the contents of thawed fish, etc., and which saves labor by reducing the power required for taking out the contents of the thawed fish.

[Conventional technology]

BACKGROUND ART Conventionally, as a device for taking out contents in a tank, a device for taking out contents in a tank in a rapid thawing machine for frozen fish is known.

As shown in FIG. 5, the device for taking out the contents in the tank of the rapid thawing machine for frozen fish has an inner tank 2 disposed inside an outer tank 1, the outer tank 1 is a water tank, and the inner tank 2 is a water tank. It is formed as a net. Generally, a special nozzle 3 provided at the bottom of the water tank (outer tank 1) generates mixed particles of circulating water and air to cause rotational convection of the thawing liquid in the water tank 1. In addition to making the temperature inside tank 1 uniform,
The contents (frozen fish) are brought into even and sufficient contact with the thawing liquid, resulting in rapid thawing.

After the frozen fish is thawed, when taking out the thawed fish, the inner tank 2 is lifted horizontally by a hoisting device (not shown) until the bottom surface of the inner tank 2 reaches the upper end of the aquarium 1. The rear end is lifted and tilted approximately 45 degrees, and the front plate 2c is opened to take out the defrosted fish (contents) out of the aquarium 1.

Therefore, according to this device, frozen fish can be thawed and taken out continuously, which has the advantage of improving work efficiency.

[Problem that the invention seeks to solve]

However, in the case of the above-mentioned device for removing the contents inside the tank, such as the thawing machine for frozen fish, the inner tank 2 itself must be lifted and then tilted, although this method is easier than the scooping method that had been used before. This requires a large amount of power.

Depending on the size of the inner tank for taking out the contents, the overall height of the device is bulky and the installation location is limited.

When the thawed fish is discharged, the thawed fish moves diagonally across the top and bottom of the inner tank at once, so the contents themselves are easily damaged.

It has been pointed out that there are problems such as:

The present invention was devised in response to the above-mentioned problems, and its purpose is to reduce the power required to take out the contents in the tank, and to To provide a device for taking out contents in a tank, which can take out contents without damaging them too much.

[Means for solving problems]

As a means for achieving the above object, the device for taking out the contents in a tank of the present invention has an inner tank and an outer tank, and moves the inner tank upward to remove the contents in the inner tank or the outer tank. In a device for taking out contents such as thawed food in a tank, the inner tank is formed of a pair of left and right opposing members, the opposing bottom portions of the opposing members are joined in a flexible manner, and the inner tank is formed of a pair of left and right opposing members. one member is made to fall toward the other member with the joint part as an axis, and the other opposing member is engaged with the upper end of the outer tank by a pivot support, etc. The other facing member is formed to fall over to the outside of the outer tank,
The structure is such that the contents in the tank can be discharged by the overturning.

Here, in the above configuration, the angle at which one of the opposing members falls toward the other member is usually limited by a stopper, and the pair of opposing members are arranged so that the angle at which one of the opposing members falls toward the other member is limited by the stopper, and the pair of opposing members are arranged so that the angle at which one of the opposing members falls toward the other member is limited by a stopper. It is an L-shaped symmetrical member, and the inner and outer tanks are generally rectangular, with the outer tank being a water tank and the inner tank being formed of a porous material (for example, configured as a patched metal), a screen-like material, a net-like material, etc. are doing. Furthermore, a hinge is used for the joining axis of the pair of L-shaped symmetrical members. Note that in this specification, the term "tank" is not limited to a tank such as an aquarium, but is a concept that generally includes a container (such as a bucket).

[Effect]

In the device for taking out contents in a tank according to the present invention based on the above configuration, one opposing member falls toward the other opposing member around the joint axis on the bottom of the inner tank, and when the falling ends at a desired angle, This time, the other opposing member is lifted around the pivot at its upper end and falls over. Then, the opening portion of the upper surface of the other opposing member is inclined diagonally downward, and the one opposing member that has fallen first is in a nearly inverted state.

Therefore, during these series of overturning operations, the contents in the tank are automatically discharged and taken out of the outer tank by the movement (upward movement) of the inner tank.

As described above, the contents removal device of the present invention is characterized in that the bottom of the inner tank is configured to be freely bendable, and the contents such as frozen fish can be automatically discharged even in the bent state. , which is significantly different from conventional devices of this type.

〔Example〕

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

Here, FIGS. 1 to 3 show embodiments of the present invention,
Figure 1 is a plan view, Figure 2 is a sectional view taken along line A-A in Figure 1,
FIGS. 3A, 3B, 3C, and 3 are explanatory diagrams of operating states.

The device for taking out contents in a tank in this embodiment is used in a low-temperature thawing machine for frozen fish such as frozen mackerel and frozen sardines as frozen bait in aquaculture.

That is, the apparatus of this embodiment is roughly composed of an outer tank 1, an inner tank 2, and a hoisting device 3 for the inner tank 2.

The outer tank 1 is a rectangular water tank made of known stainless steel, and special nozzles 1' are provided at the bottom of the tank 1 at regular intervals in the longitudinal direction of the tank 1 so as to face each other.

The inner tank 2 has a substantially similar shape to the rectangular water tank 1, but the inner tank 2 has a pair of L-shaped symmetrical members 2.
a and 2b are opposed to each other, and the abutting ends of the bottom surfaces 4a and 4b are connected by a hinge 5. The inner tank 2 is pivotally supported (engaged and supported) with the upper end 1'' of the outer tank 1 at the upper end 2b' of the L-shaped symmetrical member 2b forming the inner tank 2. It is designed to rotate as a shaft.Here, the inner tank 2
The shaft support (engagement/support) between the inner tank 2 and the outer tank 1 is not at the upper end 2b' of the inner tank 2, but at the lower end 2b'' or between the upper end 2b' and the lower end 2b'' as necessary. It may be performed at any position.

Each L-shaped symmetrical member 2a, 2b is framed by stainless steel frames 6, 6... and then a rust-proof net is stretched over the L-shape, and the L-shaped symmetrical member 2a,
Both sides 7a, 7a, 7b, 7b of 2b
A rectangular net is also placed on each side. Then, an inner tank shaped like a bucket container is configured.

Each L-shaped symmetrical member 2a, 2b is partitioned by a net stretched over partition frames 8, 8... at regular intervals in the longitudinal direction (depending on the size of the inner tank, etc.). , the partition frames 8, 8... may not be provided). Further, both sides 7a, 7a, respectively of the L-shaped symmetrical members 2a, 2b on which the rectangular mesh is stretched
One of the two side surfaces 7b, 7b is slightly fitted 7c into the end of the other side surface 7a, 7a. Here, the fitting portion is
The structure is such that it can be sealed with various sealing materials as necessary.

One L-shaped symmetrical member 2a of the L-shaped symmetrical members 2a, 2b is rotated and tilted around the hinge 5 toward the other L-shaped symmetrical member 2b, but the angle of inclination is different from that of the other L-shaped symmetrical member 2b. Side surfaces 7b, 7b of symmetrical member 2b
The frame 6 is configured to be limited by a stopper 9 projecting inwardly from the frame 6 of the frame 6.

The hoisting device 3 is an ordinary known hoist, and the tip of the hoisting rope 10 is connected to the corner portions 1 at both ends of one L-shaped symmetrical member 2a.
1 and 11.

Next, to describe the operation of this embodiment, as shown in FIG. , 11, one L-shaped symmetrical member 2a rotates and tilts toward the other L-shaped symmetrical member 2b around the hinge 5, as shown in FIG. 3A. Then, the side upper end frame 6 of one L-shaped symmetrical member 2a comes into contact with the stopper 9. Then, when the hoisting device 3 is subsequently driven to pull the rope 10, the other L-shaped symmetrical member 2b rotates so that the top opening 12 becomes the side opening, as shown in FIG. At the same time, one of the L-shaped symmetrical members 2a is in an inverted tilted state, and the contents of the frozen fish are
The contents of the other L-shaped symmetrical member 2b are also simultaneously taken out of the outer tank 1 by the force of the falling discharge, while being discharged to the outside of the outer tank by natural falling due to the inverted slope. When the rope 10 is further pulled, the other L-shaped symmetrical member 2b also tilts toward the outside of the outer tank 1, as shown in FIG. is completely removed. After the state shown in FIG. 3D is reached, the inner tank 2 is accommodated in the outer tank 1, and returns to the initial state.

Since the first step during the tilting action of the inner tank 2, that is, the operation shown in Fig. 3A, is carried out within the tank 1, the thawed fish contents are reduced in contact with each other due to the presence of water. , injuries are reduced. Then, the fish immediately moves toward the other L-shaped symmetrical member 2b. In addition, since these tipping operations are performed underwater, the buoyancy of the water allows the tipping to be done with light power.

In the case of this embodiment, the device is embodied as a thawing machine for frozen fish, and the thawed fish as the contents moves within the thawing solution, so the damage is reduced.
In addition, since at least the bottom of the inner tank 1 is formed of a net-like body 8, when the thawed fish is discharged,
It has the advantage that only the thawed fish can be discharged even after it has been sufficiently drained.

Incidentally, in the above description, the structure in which the outer tank and the inner tank are integrally constructed has been described, but the structure can also be embodied in a thawing tank in an existing thawing machine. In this case, the existing tank will constitute the outer tank.

It should be noted that the present invention is not limited to the embodiments described above, and it is obvious that modifications can be made without changing the gist of the present invention. The L-shaped symmetrical members of the outer tank 1 may have different sizes.
If a cover made of a plate is provided on the L-shaped symmetrical member 2b on the upper part of the container, and the cover can be opened and closed by rotating around the coaxially supported part, it can be used as a chute for taking out the contents. be able to. Furthermore, even if it is not the thawing machine mentioned above, it can be used for plating treatment tanks, and by making the inner tank a plate rather than a net, it can be used for various extraction purposes such as clear water pumping equipment such as aeration tanks. It can also be used in devices (for example, devices for taking out objects to be cleaned in various cleaning devices, devices for taking out boiled foods in food processing, etc.).

In addition, in the above-described embodiment, the bent part for bending the bottom surface of the inner tank was formed with a hinge, but other parts may be used as long as they have the same effect. It goes without saying that the position of the bent part does not necessarily have to be located at the center, but can be arbitrarily changed in consideration of the type of contents, inclination angle, and installation location. In addition, in the above-described embodiment, the positions of the shafts of the outer tank and the inner tank are fixedly supported at the upper end of the outer tank, but the upper end of the outer tank is extended upward. It is clear that, as such a structure, a plurality of fitting holes, which are pivotally supported by the inner tank, may be provided at appropriate intervals in the region, so that the position of the pivot support can be changed as appropriate. This configuration has advantages such as the ability to easily adjust the position for taking out the contents in the inner tank and the position for moving the contents to a belt conveyor or the like in the next process.

Furthermore, it is clear that the present invention includes the structure shown in FIG. 4 as the inner tank. That is, it also includes a configuration in which the bottom surface of the inner tank is bent at locations other than the abutting portions. In the case of this configuration, the opening for taking out the contents can be further narrowed, so that the contents can be taken out smoothly, and the structure is compact. Also,
This is effective when used in equipment with large tanks.

〔Effect of the invention〕

As is clear from the above description, according to the device for taking out the contents in the tank of the present invention, when tipping the inner tank, there is no need to lift it up to the top of the outer tank, and most of the contents remain inside the outer tank (water tank). Since it can be tilted, the power required can be reduced and labor can be saved, and damage to the contents can also be reduced.

Further, according to the device for taking out the contents in the tank of the present invention, the contents can be taken out easily and smoothly without the trouble of removing the take-out side plate of the inner tank during tilting and taking out the contents, and the contents can be taken out easily and smoothly with a small amount of power. Since the top opening can be directed downward, it has various effects such as easy cleaning.

Further, according to the device for taking out contents in a tank of the present invention, the bottom surface of the inner tank for taking out the contents is bent as necessary, and the top surface of the inner tank in a state where the inner tank is tilted can be bent. Since the line facing the bottom surface can be shortened, the entire device can be made compact, and it also has the effect of being able to be installed in a location, especially a location with a low room height.

Furthermore, according to the device for taking out contents in a tank of the present invention, in addition to taking out thawed fish in a thawing machine, it can be applied to a device for taking out contents in various devices such as taking out pecked processed products in a plating treatment tank. has.
