Abstract

PURPOSE:To improve a dehydration rate and to make the dehydration continu ous by rotating an endless filter cloth belt by its meshing by stretching it on the right and left dehydrating drum gears having numerous water running through holes and compressing the body to be dehydrated by the meshing pres sure of the gear. CONSTITUTION:The right and left dehydrating drum gears 16a, 16b having numerous water running through holes communicating into the drum are arranged freely meshingly and rotatably on a tooth crest and bottom land. The right and left belt pressing gears 20a, 20b are arranged by meshing to the gears 16a, 16b at the upper part of the gears 16a, 16b. The right and left endless filter cloth belts 41a, 41b are stretched on the gears 16a, 16b, gear pressers 20a, 20b and receiving rollers 36a, 36b. When the body to be dehydrated is input into a hopper 42, the gear 16a, 16b are rotated by meshing and the dehydration is executed via the belt 41a, 41b with the meshing pressure. The dehydration rate is improved because the dehydration is executed with high meshing pressure and it is done in succession.

The material is dropped into the container and discharged to the outside. In the figure, 56a and 56b indicate sensing switches.

Effects Continuous dehydration device 55 that implements the continuous dehydration method according to the present invention
, the left and right rotating shafts 23a and 23b mounted on the support frame 22 on the back of the machine frame 1 are rotated in conjunction with each other by the first motor 26, and the left and right rotating shafts 23a and 23b are further linked with the left and right dewatering drum gears 16a, 1.6b. At the same time, the left and right holding rollers 33a and 33b are rotated by the left and right second motors 34a.

34b, the left and right receiving rollers 36a, 36b are driven and rotated by the left and right third motors 37a, 37b, respectively, and the left and right endless filter cloth belts 41a, 41b, which are engaged with the outer surfaces of the left and right dewatering drum gears 16a, 16b, are sequentially moved inward to each other. It is something that moves people. Therefore, when the material to be dehydrated is put into the input hopper 42, the rotary cutter 4 in the discharge rectangular tube 43 at the lower end
4, the material to be dehydrated is cut into small pieces and flows downward, and is closely attached to the toothed surfaces of the left and right dewatering drum gears 16a, 16b by the mesh feeding operation of the left and right belt holding gears 20a, 20b and the left and right dewatering drum gears 16a, 16b. The material to be dehydrated that has flowed down to the joint of the left and right endless filter cloth bells h41a and 41b is pressed by the mutual meshing of the teeth 14 of the left and right dehydration drum gears 16a and 16b, and the moisture is removed through the holes formed on the tooth tips and tooth bottoms. Water is dewatered from the water hole 15 into the left and right dewatering drum gears 16a, 16b. In this case, the front and rear movable bearings 12 that pivotally support the rotating shaft 17b of the right dehydration drum gear 1.6b slide to the right side by the elasticity of the coil spring 11 depending on the remaining amount of the dehydrated cake of the object to be dehydrated, thereby adjusting the meshing gap. It is something. The dewatering liquid that has flowed into the left and right dehydration drum gears 16a and 16b is the left and right dehydration drum gear 16a.

Dewatering tray 4 below the water passage hole 15 on the lower surface of 16b
0 and is discharged to the outside, and the dehydrated cake is passed through the left and right dehydration drum gears 16a and 16b to the left and right endless filter cloth bells).
41a, 41b are separated and guided diagonally downward to the outside, so that they fall directly into the collection hopper 53 below and are discharged to the outside by the discharge conveyor 54. At the same time, the left and right brush rollers 48a, 48b are endless. Filter cloth belt 4
The purpose is to clean the clogging of the filter cloth belt while brushing the lower surfaces of the filters 1a and 41b. Left and right endless filter cloth bell) 4
1a and 41b are those that are guided upward after moisture is removed by left and right dewatering rollers 39a and 39b that are in pressure contact with the left and right receiving rollers 36a and 36b while circulating, and are guided upward by left and right tension rollers 52a and 52b). · If tension is applied to the belt, but if there is too much slack, the contacts of the sensing switches 56a and 56b sense this and speed up the rotation of the second and third motors 34 and 37.

Therefore, in the present invention, sludge, fruit and vegetable processing waste, etc. can be dehydrated continuously and with a high dehydration rate, and the mechanism is simple and the production cost is low, and it is possible to dehydrate fruits and vegetables. It can also be used as a juice extractor and has the remarkable effects mentioned above.
