This compression dewatering apparatus 10 is provided with a charging hopper 11 at an upper portion, and a pair of crushing rollers 70 and 75 is provided at a lower portion of the charging hopper 11, and a garbage is compressed and dewatered at a lower portion of the crushing rollers 70 and 75. A screw 80 is provided. A mesh screen 35 is provided on the peripheral surface of the screw 80 so that the water decompressed and dewatered from the garbage is discharged to the outside. At the rear end of the screw 80, a discharge port 37 for discharging the compressed and dewatered garbage to the outside is provided.

[0004] In such a compression dewatering apparatus 10, when garbage having a high viscosity is introduced, the introduced garbage adheres to the inner wall surface of the introduction hopper 11 and generates an odor. Therefore, there is a problem that the use is troublesome, for example, it must be washed with water after use. There is also a problem that it is difficult to remove a bad smell generated during the operation of the dehydrator. Further, the mesh screen 35 is provided with countless fine through-holes, but the through-holes are clogged with garbage transferred under pressure by the screw 80, generating a bad smell, and further dewatered from the garbage. There is a problem that water is not discharged smoothly.

Therefore, the garbage supplied through the charging hopper 11 is
While passing between 0 and 75, the crushing blades 73 and 78 are crushed by meshing, so that the particle size of the crushed garbage is
Determined by the size of 73 and 78. Therefore, in order to pulverize the garbage finely, the size of the crushing blades 73 and 78 must be formed small. Is difficult to crush. Therefore, when trying to finely crush the garbage, the garbage is usually crushed once by crushing rollers 70, 75 having crushing blades 73, 78 of a large size, and then crushing blades 73, 78 of a smaller size. The garbage must be finely crushed by the crushing rollers 70 and 75 having crushing rollers.

[0006] However, passing through several pulverizing steps to pulverize the garbage into small pieces in this way requires a longer working process and a larger number of pulverizing rollers 70 and 75, which requires equipment. The number of parts increases, and the cost of equipment increases. More crushing rollers 70,
There is a problem that power consumption increases for driving the 75.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a sectional view of a garbage processing apparatus according to one embodiment of the present invention. According to this, a pair of crushing rollers 21 and 26 are provided below the input hopper 11 of the garbage disposal apparatus 10, and a pair of screws 31 and 36 are provided below the crushing rollers 21 and 26. Also,
A screen 35 is provided on the peripheral surfaces of the screws 31, 33. These basic configurations have almost the same configuration as the conventional configuration.

In the present invention, spray nozzles 50 and 53 connected to, for example, a water pipe are provided on the inside of the charging hopper 11 and the peripheral surface of the screen 35. Thereby, when garbage with high viscosity is thrown in, dirt adhering to these parts can be easily washed away, and these parts can be kept clean and generation of a bad smell can be prevented.

More specifically, the spray nozzles 50 and 53 are provided on the inner upper end of the charging hopper 11 and the peripheral surface of the screen 35, respectively, and these are connected to a water supply pipe or the like by a hose 55 to inject water at high pressure. It is good to be constituted so that it can do. At this time, the injection nozzle 50 provided inside the charging hopper 11 supplies water to the inner surface of the charging hopper 11 so that the garbage to be charged adheres to the inner wall surface of the charging hopper 11 or This makes it possible to smoothly slide down to the lower part without performing, and keeps a clean state as compared with the related art, and suppresses the generation of offensive odor in combination with the fact that the supplied water absorbs offensive odor. Further, the spray nozzle 53 provided on the periphery of the screen 35 sprays the supplied water at a high pressure toward the screen, thereby preventing the food waste to be dewatered under pressure from being clogged in the through-hole of the screen 35. And reduce the generation of odors.

Further, the pair of crushing rollers 21 and 26 can be configured so that the garbage can be crushed smaller while rotating at different speeds to improve the compression dewatering efficiency. This pair of crushing rollers 21, 26
Are provided in parallel inside the compression dehydration apparatus 10 so as to be located at the lower part of the input hopper 11 of the compression dehydration apparatus 10, and provided with shafts 22 and 27 at the center thereof, and on the outer peripheral surface of the shafts 22 and 27. The crushing blades 23 and 28 having a small thickness are formed at regular intervals. At this time, the crushing blade formed on each of the crushing rollers 21 and 26

The crushing blade 28 of the crushing roller on the other side is configured to pass through the space between 23.

The pair of crushing rollers 21 and 26 are rotated at relatively different speeds. That is, the crushing roller 21 is divided into a supporting crushing roller 21 that rotates relatively slowly and a cutting crushing roller 26 that rotates faster than that.

At this time, the supporting crushing roller 21 has a front surface 23b of the crushing blade 23 (when viewed from the rotation direction) which is inclined by approximately 20 ° with respect to the diametrical direction, whereas the back surface 23a has a diametrical direction. The garbage is formed to have an inclination of about 10 ° so that the garbage is supported by the back surface 23a of the crushing blade 23. Thereby, it is possible to prevent the garbage from slipping due to the inclination angle in the pulverizing process.

Also, the cutting crushing roller 26
The crushing blade 28 has a portion which is curved round (when viewed from the rotation direction) on the back surface 28b of the crushing blade 28, and
The front surface 28a is formed so as to be inclined at an angle of about 6 ° with the diametrical direction. This prevents the garbage from slipping due to the inclination angle during the cutting process.
