Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a kitchen waste processing machine that crushes and dehydrates kitchen waste.

[Prior Art] Conventionally, centrifugal dehydration methods and compression dehydration methods are known as methods for dewatering kitchen waste pulverized in a pulverizing chamber. When performing sufficient dehydration, the centrifugal dehydration method requires a long dehydration time, whereas the compression dehydration method has the advantage of being able to reliably dehydrate in a short time.

Japanese Patent Publication No. 57-54178 discloses a kitchen waste processing machine employing a compression dehydration method. The dewatering section of the kitchen waste processing machine in the embodiment of this publication consists of an inner cylinder with a large number of through holes, a screw shaft installed upright in the center of the inner cylinder, and an inner cylinder screwed onto the screw shaft. It consists of a pressure plate having a diameter equal to the diameter of the cylinder, a presser plate attached to the upper part of the screw shaft, and a handle for rotating the screw shaft.

In the dewatering section configured as described above, the kitchen waste crushed in the crushing section is accumulated in the inner cylinder with the presser plate removed and the pressure plate lowered to the maximum extent. When the kitchen waste has accumulated to the top of the inner cylinder, fit the presser plate onto the top of the screw shaft to fix it, and then rotate the handle. When the handle is rotated, the screw shaft is rotated, and the pressurizing plate is raised to compress the kitchen waste in the inner cylinder between it and the holding plate, and the water in the kitchen waste is released from the through hole in the inner cylinder to dehydrate it. When dewatering is complete, remove the presser plate from the top of the screw shaft and rotate the handle again to raise the pressure plate and discharge the dehydrated kitchen waste.

[Problems to be Solved by the Invention] In the kitchen waste processing machine disclosed in the above-mentioned publication, when a certain amount of kitchen waste accumulates in the inner cylinder, grinding is stopped and dewatering is performed, and when the dewatering is completed, the holding plate is removed and the kitchen waste is removed. Perform discharge.

Therefore, there is a problem in that only one of a series of processing operations such as crushing, dewatering, and discharging of kitchen waste can be performed at any time, resulting in low processing capacity.

The first outer circumferential surface is formed so as to have a sufficiently large gap with the side surface of the dewatering screen to cooperate with the dewatering screen to define a food waste input section, and the third outer circumferential surface is The surface cooperates with the dewatering screen to define a compression dewatering section for kitchen waste, so that the gap between the surface and the dewatering screen is sufficiently small, and the second outer peripheral surface has a conveying section for conveying the kitchen waste to the discharge port. It is configured by being formed so as to come into contact with the side surface of the dewatering screen.

[Function] In the kitchen waste processing machine of the present invention having the above configuration, the kitchen waste crushed in the crushing chamber is charged into the input section defined by the first outer circumferential surface of the compression member rotating within the dewatering screen. The input kitchen waste flows down onto the water shield plate provided on the outer periphery of the compression member, and is sent to the compression dewatering section defined by the third outer circumferential surface in such a state that it sticks to the side surface of the dewatering screen due to centrifugal force. It will be done. The kitchen waste is then compressed between the third outer peripheral surface and the side surface of the dewatering screen, and the moisture is released through the small holes provided in the dewatering screen. In this way, the kitchen waste is sent to the second outer peripheral surface while being dehydrated, falls to the bottom of the dewatering screen through the notch formed in the water shield plate, and is conveyed by a conveying member to the discharge port formed at the bottom of the screen and discharged. be done.

Next, the operation of this embodiment will be explained.

When the motor 43 is energized, the motor shaft 45 rotates, causing the gears 47 and 49 to rotate. Due to the rotation of the gear 47, the gear 5
3, the shaft 27, and the rotating plate 23 are rotated. The rotation of the gear 49 rotates the gear 51, the hollow shaft 41, and the compression member 33. The rotation direction of the compression member 33 is indicated by arrow A in FIG.
There is an R force direction.

Kitchen waste containing moisture is transferred from the kitchen waste input opening 17 to the crushing chamber 19.
When the kitchen waste is thrown into the station, it is pressed against the fixed blade 21 by the centrifugal force received from the rotating plate 23, and is pulverized by the fixed blade 21 and the rotating blade 25. The crushed kitchen waste 1 passes through the notch of the fixed blade 21 and falls onto the inclined surface of the feed plate 35.

The kitchen waste on the feed plate 35 is removed from the first outer peripheral surface 3 of the compression member 33.
It falls onto the water shield plate 37 from the input section defined by 3a.

The kitchen waste on the water shield plate 37 is conveyed to the compression dewatering section defined by the third outer circumferential surface 33c while sliding on the water shield plate 37 so that it sticks to the side surface of the dewatering screen 31 due to centrifugal force. Ru. While being transported, the kitchen waste is compressed between the third outer circumferential surface 33c and the side surface of the dewatering screen 31,
The water is released from small holes formed on the side surface of the dehydration screen 31 and is discharged from the drain port 29 of the dehydration palm 13.

The dehydrated kitchen waste that passes through the compression dewatering section falls through the cutout of the water shield plate 37 to the bottom of the dewatering screen 31. The kitchen waste is then collected by a conveying member 65 and conveyed to three discharge ports, and from the discharge port 39 to the reception ports 6 of five dust boxes.
1 and is discharged into the plastic bag 63. Since the conveyance member 65 rotates while coming into contact with the side surface of the dewatering screen 31, the kitchen waste compressed and attached to the side surface of the dewatering screen 31 is also reliably collected and discharged.

The present invention is not limited to the embodiments detailed above, and various changes can be made without departing from the spirit thereof. For example, the compression member 33 may have a series of two or more outer circumferential surfaces including a first outer circumferential surface 33a, a second outer circumferential surface 33b, and a third outer circumferential surface 33C. Also,
By attaching a brush to the portion of the conveying member 65 that comes into contact with the side surface of the dewatering screen 31, clogging of the dehydrating screen 31 can be prevented.

[Effects of the Invention] As explained above, according to the present invention, a compression member having a water shield plate and a conveying member and defining an input section and a compression dehydration section is rotatably provided within a dehydration screen. Since a discharge port is formed at the bottom of the dewatering screen, the kitchen waste crushed in the crushing chamber is continuously compressed and dehydrated and discharged.

Therefore, it is possible to realize a kitchen waste processing machine that uses a compression dewatering method that can perform reliable dewatering in a short period of time, and has a high processing capacity that can perform a series of processing operations such as crushing, dewatering, and discharging kitchen waste continuously and simultaneously, which will improve the industry. The effect is extremely large.
