Abstract

PURPOSE:To improve a dehydration rate and to make the dehydration continuous by fixing a filter cloth onto the gear face of a pair of the right and left dehydrating drum gears forming numerous water running through holes and performing a compressed dehydration by a rotating meshing pressure by feeding the body to be dehydrated to the gear meshing face. CONSTITUTION:A tooth is formed by the elastic body of an urethane rubber, etc., on the outer periphery of a metal drum and a pair of the right and left dehydrating drum gears 16a, 16b are formed by fixing a filter cloth on the gear face having numerous water running through holes. The drum gears 16a, 16b are then driven by their rotation via a motor 24, endless chains 23a, 23b and a chain wheel. The body to be dehydrated fed from an input hopper 25 is cut by a rotary cutter 27 and the dehydration is executed by the meshing pressure of the gears 16a, 16b. The moisture is discharged to a dehydrating pan 29 and a solid body by a hopper 30 and conveyor 31. The dehydration rate is thus improved because of being executed by a high meshing pressure and made continuous by the continuous rotation of the gear 16a, 16b.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a continuous dewatering method and a continuous dewatering apparatus for sludge, fruit and vegetable processing waste, etc.

Conventional technology Conventionally, sludge dewatering devices include centrifugal dehydrators, vacuum dehydrators,
A pressure dehydrator or the like is used, and a continuous dehydrator using a belt filter is used to dehydrate the orange juice layer.

Problems to be Solved by the Invention However, in centrifugal dehydrators, vacuum dehydrators, etc., the equipment that can perform continuous dehydration operations is expensive, and in continuous dehydrators using belt filters, the compression pressure is low. Since the dehydration rate was low, the dehydration rate was 40 to 50, making complete dehydration impossible.

In order to solve these problems, the present invention has a pair of left and right dehydration drum gears that have a large number of water holes in the top and bottom surfaces of the teeth and have a filter cloth pasted on their outer surfaces. A dewatering method and a dewatering device in which the material to be dehydrated flows down into the meshing part and water is removed from the material by the meshing pressing force of left and right dehydrating drum gears, and the dewatering device has a high dewatering rate and can perform continuous dewatering work. It is characterized by this.

1 is installed, teeth 13 are molded on the outer periphery of the metal drum 12 using an elastic material such as urethane rubber, and a large number of water passage holes 14 that communicate with the inside of the drum are formed on the top and bottom surfaces of the teeth. Left and right dehydration drum gears 16a and 16b are formed with a filter cloth 15 woven from hemp or chemical fibers fixed to the bottom surfaces of the teeth, and the rotation shaft 17 of the left dehydration drum gears 1 and 6a is mounted on front and rear facing bearings 3 and 3.
A movable bearing 11 that pivots and faces front and rear. ．． 1
The rotating shaft 1 of the right dewatering drum gear 16b is attached to the bearings 6, 6 of 1.
A base frame 18 is connected to the lower end of the rear side of the machine frame, and left and right rotation shafts 19a, 19 are attached to the upper surface of the base frame 18.
left and right gears 20a, 20b and left and right chain wheels 21a, 2 which are pivotally supported by the left and right rotating shafts 19a, 9b and meshed with each other.
1b, and the chain wheels 21a, 2], b and the chain wheels 22a, 221] of the rotation shafts 17a, 17b of the left and right dehydration drum gears 16a, 1.6b are connected to endless chains 23a, 23b, respectively.
The first motor 24 installed on the base frame 18 and the left rotating shaft 19a are interlocked by an interlocking mechanism, and the input hopper 25 is installed on the top surface of the machine frame 1 to connect the left and right dewatering drum gears 1.
6a.

A rectangular discharge tube 26 is suspended above the engagement of the rectangular discharge tube 26, and a rotary cutter 27 is pivotally supported within the rectangular discharge tube 26. A dewatering tray 29 is installed below the dewatering drum gears 16a and 16b, and a collection hopper 30 is installed below the meshing.
A continuous dewatering device 32 is constructed in which a discharge conveyor 31 is installed from below the collecting hopper 30 to the side of the machine frame 1, and the left and right dewatering drum gears 1.6a and 16b are inwardly meshed and rotated while feeding. The sludge, fruit processing waste, etc. that have been put into the hopper 25 flow down to the meshing part, and the water is filtered and dehydrated into the dehydration drum gear by the meshing pressure of the left and right dehydration drum gears 16a and 16b, and discharged to the outside, and the dehydrated solids are dehydrated on the left and right sides. Drum gear 16a, 16
It is made to fall below the meshing part b and discharged to the outside.

Effects Continuous dehydration device 32 implementing the continuous dehydration method of the present invention
In this case, the motor 24 rotates the left and right rotating shafts 19a, 1.
Left and right dewatering drum gear 1.6 while rotating 9b in conjunction with each other.
A, ], 6b are meshed and rotated inwardly to feed materials to be dehydrated, such as sludge and processed fruit and vegetable scraps, into the input hopper 25. After being cut into small pieces, the water is compressed by the mutual meshing pressure of the teeth 13 while flowing down to the meshing part of the left and right dewatering drum gears 16a and 16b, and the water is released into the filter cloth 1 on the outer surface.
5. The water flows into the left and right dehydration drum gears through each of the water holes 14, flows down to the dewatering tray 29 installed below at the bottom of the dehydration drum gear, and is discharged to the outside. As the teeth 13 of the drum gears 16a, 16b rotate downward, they fall downward, are transferred from the collection hopper 30 to the discharge conveyor 31, and are discharged to the outside. The rotating shaft 17b of the right dehydration drum gear 16b is supported by the movable bearing 11.11, so that
The meshing gap is adjusted from -6 to 100 degrees while being pressed toward the right by the remaining amount of the dehydrated cake that has been dehydrated from the dehydrated material.

Therefore, in the present invention, the water can be removed by compressing the material to be dehydrated by the meshing pressure of the dehydration drum gear, and the dehydration rate is high and continuous dewatering work can be performed. In addition, it can also be used as a juicer for fruits and vegetables, and has the above-mentioned remarkable effects.
