The pressure of the high-pressure water source is 1-5MPa, and in the embodiment, the pressure of the high-pressure water source is 1.6 MPa. The external high-pressure water source can be pressurized by adopting a high-pressure water pump and other modes.

The diameters of the through hole of the locking seat 1302 and the through hole of the upright locking seat 1304 are both larger than the outer diameter of the bolt 1303, so that the bolt 1303 can be inserted into the through hole of the locking seat 1302 and the through hole of the upright locking seat 1304. The locking cylinder 1301 may employ an air cylinder or a hydraulic cylinder. The locking mechanism 13 can fix the base plate 10 and the filter plate 4 on the upper part of the base plate 10, thereby leaving enough space for the hydraulic oil cylinder 8 to overhaul and replace.
In other embodiments, the filter press further comprises a replacement filter plate 20 comprising a plate body 2001 and a replacement seal 2002, and a hanger pin. The replacement filter plate 20 has the same outer dimensions as the filter plate 4 and has a replacement seal 2002 on its lower surface that is identical in construction to the seal 407. The replacement filter plate 20 is arranged below the top plate 1 and above the filter plate 4 and is connected with the filter plate 4 through the connecting hanging plate 3. The replaceable filter plate 20 can also be arranged below the filter plate 4 and above the bottom plate 10 and is connected with the filter plate 4 through the connecting hanging plate 3. The replacement filter plate 20 does not have a solid-liquid separation capability, and is only used for replacing the filter plate 4, so that the overall height of the filter plate 4 is ensured to be unchanged, and further, the overall sizes of the filter presses with the same area and different models of the single-layer filter plate are unchanged. The filtering area of the vertical filter press is as follows: the area of the single-layer filter plate is equal to the number of the filter plates, and the filter presses of different models are selected according to different filtering capacities. The filter plates 4 are replaced by the replacement filter plates 20, so that the standardization of the filter presses with the same area and different models of the single-layer filter plates is realized on the premise of meeting the solid-liquid separation capability, the design and manufacturing difficulty is reduced, and the cost is reduced.
The above-described embodiment is applicable to a vertical filter press, and particularly to a vertical filter press in which the single-layer filter plates 4 have a filter area of 2.5 square.
When the filter plate lifting device is used, a hydraulic pump of the hydraulic station 18 is started to supply oil to the hydraulic oil cylinder 8, a piston rod of the hydraulic oil cylinder 8 is lifted to drive the bottom plate 10 to lift, and then the filter plates 4 are driven to lift until all the filter plates 4 between the bottom plate 10 and the top plate 1 are completely contacted and pressed and keep a certain pressure, and the pressure is used for ensuring that a closed space is formed between the filter plates 4 and liquid in the filter plates 4 cannot flow out. After the slurry pump of the feeding device 19 is powered on, slurry in the slurry barrel sequentially passes through the feeding pipe 15 and the slurry inlets 406 and then enters the slurry cavities 405 of the filter plates 4. The control valve of the extrusion water pipe 16 is opened, high-pressure water enters the inner cavity of the extrusion diaphragm 404 through the extrusion water inlet 403, and the extrusion diaphragm 404 elastically expands to extrude the slurry in the slurry cavity 405. Under the squeezing action of the squeezing diaphragm 404, the moisture in the slurry in each slurry chamber 405 passes through the filter cloth 5, gathers up in the filtrate pipe 14 and is discharged out of the filter press. The remaining part of the slurry becomes dry material, which continues to be present in the slurry chamber 405 due to the barrier effect of the filter cloth 5. After the extrusion process is completed, the hydraulic pump of the hydraulic station 18 is powered off, the hydraulic pressure in the hydraulic oil cylinder 8 flows back to the hydraulic station 18, the piston rod of the hydraulic oil cylinder 8 slowly falls back to the initial position, and in the process, the filter plates 4 are pulled open layer by layer under the action of gravity and the connecting hanging plates 3 until the bottom plate 10 is static. After the driving motor of the driving device 7 is electrified, the roller body is driven to drive the filter cloth 5 to run to the position of the top roller 11, and dry materials on the upper part of the filter cloth 5 naturally fall into the material receiving hopper 6, so that the whole solid-liquid separation process is completed.
Thus, it should be understood by those skilled in the art that while exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations and modifications can be made in accordance with the principles of the invention without departing from the spirit and scope of the invention, which is broadly defined and defined herein.
