[0002]

2. Description of the Related Art In the past, the technology relating to this kind of solid-liquid separation device has been remarkably developed, and a number of devices or inventions / inventions have been found. Among them, the following documents are cited as the prior art related to the press dehydration press (normal filter press). (1) There is a sludge dewatering device disclosed in JP-A-1-123611. The present invention stores sludge particles in the space formed by the upper and lower filtration plates, and squeezes and dewaters the sludge particles by the rise of the lower filtration plate, and lowers the pressure tube after squeezing and dewatering to open the squeeze cake, After that, the pressed cake is extruded. (2) There is a solid-liquid separation method disclosed in JP-A-63-218203. The invention provides a piston in a cylinder that can move up and down, forms a compression chamber in the cylinder, and discharges the mother liquor from the compression chamber through a filter provided in the compression chamber. This is a structure in which the crystallized product and the mother liquor are squeezed and separated by going up and down in a facing relationship. (3) There is a dewatering device for construction sludge disclosed in JP-A-2-135104. According to the present invention, the filter cloth contained in the compression chamber is compressed and dehydrated by using an air bag and a through hole. (4) There is a waste treatment method disclosed in JP-A-5-330602. The invention discloses a configuration in which raw garbage is squeezed and dehydrated via a piston.

[0003]

The prior arts described in detail above all employ a special device or method for taking out the pressed cake, so that the structure is complicated and labor is required for the operation of taking out the pressed cake. Issues such as the need for time may be considered. In addition, since the lower surface or side surface structure is adopted as the method of extracting water (drainage liquid), fine particles (fine sludge)
There is a risk of taking in water, and there is a problem that good quality clear water cannot be generated. Furthermore, various raw-material squeezing dewatering devices have problems such as a complicated structure and difficult maintenance (handling).

[0004]

In view of the above, the present invention provides
Easy and reliable removal of the pressed cake,
The following configuration is adopted for the purpose of simplifying the device for taking out the pressed cake, producing clear water and high-quality juice that do not contain fine particles, and further simplifying the entire device. To do.

First, in the solid-liquid separation device of the first invention, a casing tube having a raw material inlet and an opening on the pressure receiving surface side, a liquid take-out portion formed on one surface of the casing tube, and the casing tube. It comprises a piston that is internally movably moved back and forth, a cylinder that moves the piston back and forth, and a pressure receiving plate that is provided on the pressure receiving surface side of the casing tube and that opens and closes the opening.

First, the solid-liquid separation device of the second and third inventions
The squeezing and dehydrating device has a horizontal casing tube having a raw material inlet on the upper surface and an opening on the pressure receiving surface side, a liquid take-out portion formed on the upper surface of the casing tube, and can be moved back and forth inside the casing tube. And a cylinder that moves the piston back and forth, and a pressure receiving plate that is provided on the pressure receiving surface side of the casing tube and that opens and closes the opening.

[0007]

The operation of the present invention (foods such as raw materials, raw garbage, fruits, etc. = input of processed material and squeezing dehydration) will be described below. The processed material introduced into the casing tube through the hopper is pushed in the direction of the arrow in FIG. 1 via the piston provided in the casing tube, and abuts against the pressure receiving plate provided in the casing tube. The squeeze is started by this. After that, as the piston further advances in the direction of the arrow in FIG. 1 through the extension of the piston rod,
Further squeezing progressed, the water generated by the squeezing,
The liquid is discharged to the outside of the cylinder tube (outside of the apparatus) via the liquid take-out portion provided on the upper surface of the cylinder tube. Then, the piston further advances, and at the time when the compression with the pressure receiving plate is completed, the squeezing and discharging work is completed, so that subsequently, the pressure receiving plate is pulled up to open the release port of the casing tube, and the piston further moves. When the piston moves forward and reaches the forward limit, the piston is located in the vicinity of the opening, and the squeeze cake is placed on the table for taking out the squeeze cake.

After that, the squeezed cake on the table is transferred to other parts or places by appropriate means. On the other hand, the pistons are sequentially replaced by contraction (retraction) of the piston rod, and finally return to the initial state, and the opening of the casing tube is closed by mounting the pressure receiving plate.

[0009] For example, in the case of raw waste to be compressed and dehydrated (the same applies to fruits, etc., hereinafter, referred to as raw waste), the raw waste is put in through a raw material inlet, and the raw material is pressed through the same operation and procedure as described above.・ Dehydration is performed. In this way, the treated wastewater (juice) is taken out of the device via the liquid take-out part, and the pressed cake (squeeze cake) is discharged to the outside of the device by opening the opening of the casing tube. . Other operations and the like are the same as those in the above example.
