Hereinafter, the food waste compression dehydration apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Food waste compression dehydration apparatus according to the present invention, as shown in Figure 1, is provided with an outer cylinder 10 is formed with a waste water discharge port (10a) on the bottom surface, in the outer cylinder 10 a plurality of side walls and bottom surface The inner cylinder 20 in which the drain port 20a was formed is inserted.

In the inner cylinder 20, a pressing plate 30 having a plurality of drain holes 30a formed on the bottom surface is inserted into the inner cylinder 20 so as to be movable, and the outer cylinder 10 and the inner cylinder 20 are provided at the center of the pressing plate 30. ), The tip of the feed screw 62 which is sequentially passed through is coupled through the bearing 61.

A drive gear 64 having an outer gear formed on an outer circumference thereof is rotatably installed at a central portion of the bottom surface of the outer cylinder 10 through a bearing 63, and the transfer screw is provided in an inner screw hole of the drive gear 64. The right side 62 is screwed in and engaged.

In addition, the outer gear of the drive gear 64 has a structure engaged with the reduction gear 65 connected to the drive motor 66.

Therefore, as the drive motor 66 is driven, when the reduction gear 65 rotates to rotate the drive gear 64 clockwise, the drive gear 64 rotates the feed screw 62 engaged with the inner gear. By pushing the feed screw 62 upward, the pressing plate 30 coupled to the upper end is pushed up.

The lid 40 is hinged to the upper end of the outer cylinder 10, the lid 40 is fixed to the fixing clamp 41. On the other hand, the bottom of the lid 40, the upper support plate 50 is elastically installed through a plurality of springs 42.

The bottom of the outer cylinder 10 is provided with a waste water discharge port (10a) for discharging the sewage of the food waste depressed by the inner cylinder 20 to the outside.

In addition, the present invention supplies or cuts power to the driving motor 66, or changes the direction of the current to drive or stop the driving motor 66, or to change the rotation direction of the motor 66, thereby reducing the pressing plate 30. The switch part 67 which raises or lowers is included.

It also includes a control means for controlling the pressing plate 30 to move only a certain stroke in the inner cylinder (20). As shown in FIGS. 2A and 2B, the control means is installed on the bottom surface of the lid 40 and is in contact with the upper support plate 50 when the upper support plate 50 is raised to move the driving motor 66. The upper limit switch 68 for stopping the rising of the pressing plate 30 and stopping the upper surface of the inner cylinder 20 and operated by the pressing plate 30 when the pressing plate 30 is located at the lowest point. And a lower limit switch 69 for stopping the drive motor 66.

Accordingly, when the switch unit 67 is turned on, as shown in FIGS. 2A and 2B, power is applied to the driving motor 66 so that the driving motor 66 rotates, and the driving motor 66 is a speed reducer ( The feed plate 62 is rotated through the 65 and the driving gear 64 to push up the pressing plate 30. As the pressing plate 30 is raised, the food waste is pressed against the upper support plate 50 to compress and dehydrate. Then, when the upper support plate 50 receives a certain amount of force through the food waste, the spring 42 is pushed up while compressing the spring 42, and when the upper limit switch 68 is turned on, the limit switch 68 operates to drive the motor 66. By cutting off the power supplied to), the rise of the crimping plate 30 is stopped. This state is a state in which the decompression process of food waste is completed.

In this state, when the lid 40 is opened and the switch portion 67 is pressed again, the stopped pressing plate 30 is raised again to push the compressed and dehydrated food waste to the outside of the inner cylinder 20. At this time, the pressing plate 30 is located at the top end of the inner cylinder 20, and in this position, the reverse limit switch 70 operates to reverse the driving motor 66 to lower the pressing plate 30 again.

When the pressing plate 30 lowered as described above operates the lower limit switch 69 installed on the bottom surface of the inner cylinder 20, the limit switch 69 stops the driving motor 66.

As described above, the control means automatically controls the lifting operation of the pressing plate 30.

Here, the pressing plate lifting means of the present invention includes those using a hydraulic device in addition to the above configuration. For example, a hydraulic cylinder can also be used as a means of elevating the crimping plate 30. If the amount of pressurized oil supplied to or discharged from this hydraulic cylinder is changed, the forward speed (the speed of the pressing plate rising operation) and the backward speed (the speed of returning) are different. Therefore, the speed of the pressing plate 30 is slowed only when the waste is compressed. When returning back, it is possible to return quickly to reduce the work cycle time.

As described above, the present invention dehydrates food waste before throwing it away, thereby preventing environmental pollution caused by sewage discharged from food waste, and recycling the dehydrated food waste after the post-treatment process such as drying and sterilization, and then recycling it into feed. As a result, it is possible to prevent the pollution of the natural environment.

In particular, the present invention has the advantage of high processing efficiency by mechanically compressing and dehydrating a relatively large amount of food waste.
