Description

Technical Field

[0001] The invention belongs to the technical field of filter presses, in particular to a filter press for silicon dioxide liquid material. Background Art

[0002] A filter press is a device that separates solids from liquids by filtering materials under pressure. It is widely used in industries such as food, chemical, environmental protection, and sewage treatment. In particular, it has unique advantages in separating sticky and fine materials. In the process of filtering out the silica solution, a filter press is usually used to process it to form a filter cake for later processing.

[0003] However, the main working parts of the filter press currently on the market are filter plates, and several filter plates are arranged in sequence. The material is dehydrated in the filter cavity between the filter plates, and the dehydrated filter cake is transferred by being put onto a conveyor belt. However, the existing filter plates are prone to causing the filter cake to adhere to the surface of the filter plates during operation. When the residue needs to be removed, the residue is not easy to fall off, and the existing filter presses need to manually clean the attached residue, which greatly affects the filtration efficiency. In addition, the filter plates will cause roller wear during movement and need to be lubricated. Currently, lubrication by manually injecting lubricating oil greatly reduces efficiency and cannot detect the content of the lubricating oil in time, which affects the service life of the equipment. Summary of the invention

[0029] A gear ring 13 is movably connected to the inner wall of the middle part of the filter plate 3. The size of the gear ring 13 is smaller than that of the filter plate 3 and a movable groove adapted to the gear ring 13 is provided on the inner wall of the filter plate 3, wherein teeth are provided on the inner side of the gear ring and the teeth are incomplete teeth and mesh with the teeth grooves on the outer side of the gear. A telescopic rod 16 is fixedly connected to the outer side of the gear ring 13, and an electric push rod 15 is fixedly connected to the inner wall of the middle part of the telescopic rod 16. A roller 6 is sleeved on the outer side of the shaft disc 12. There are two rollers 6 and they are symmetrically distributed on the outer side of the filter plate 3 and a card slot is provided on the outer side of the roller 6. The roller 6 moves along the outer wall of the frame 1 under the drive of the filter plate 3. An oil cavity 20 is provided in the middle of the roller 6, and a sponge 21 is fixedly connected to the inner wall of the oil cavity 20.

[0030] A ball 19 is movably connected to the outer side of the shaft disc 12, and a spring pin 18 is fixedly connected to the inner wall of the oil chamber 20. The size of the spring pin 18 is smaller than that of the roller 6, and there are eight spring pins 18 evenly distributed on the inner wall of the oil chamber 20, wherein the inner side of the spring pin contacts the sponge, and when the ball rotates, it contacts and squeezes the spring pin so that the lubricating oil attached to the inside of the sponge can be evenly squeezed out. A slot 22 is provided in the middle of the roller 6, and an oil drain port 17 is connected to the inner wall of the slot 22. An oil guide chamber 11 is provided on the inner wall of the shaft disc 12. There are eight oil guide chambers 11 distributed circumferentially in the middle of the shaft disc 12 and connected to the oil chamber 20, wherein an oil guide pipe is inserted into the inner wall of the middle of the fixed shaft 7, and the lubricating oil is pressurized and injected into the oil filling pipe by an external device, thereby being introduced into the inner wall of the oil chamber through the oil guide chamber 11.

[0031] Working principle: When working, the filter plate 3 is first polymerized by the compressor 2, and then the raw material is injected into the filter plate 3. When the raw material is filtered to form a filter cake, the filter plates 3 are separated from each other. At this time, the filter cake falls off along the outer wall of the groove 10. Since the filter cake cannot fall completely during the falling process, the micro motor is operated by the external control device. At this time, the gear 14 rotates, thereby further driving the gear ring 13 to make up and down reciprocating periodic movements along the inner wall of the movable groove, and at the same time, the electric push rod 15 is in operation. At this time, the telescopic rod 16 approaches the filter hole 9, and the back of the telescopic rod 16 is fixedly connected with bristles. The filter residue attached to the inner wall of the groove 10 is cleaned under the joint drive of the telescopic rod 16 and the gear ring 13;

[0032] As the filter plate 3 is in the process of aggregation and separation, the roller 6 moves along the guide rail on the top of the frame 1. After long-term operation, the roller 6 will cause certain wear and tear. Lubrication is usually achieved by manually adding lubricating oil. An external oil guide pipe is now fixedly connected to the inner wall of the fixed shaft 7 to inject lubricating oil into the oil guide chamber 11. The lubricating oil is introduced into the oil chamber 20 through the oil guide chamber 11. When the roller 6 rotates along the outer side of the shaft disc 12, the ball 19 also rotates along the outer side of the shaft disc 12. Since the ball 19 will contact the sponge 21 when rotating, the spring ejector pin 18 will evenly adhere the lubricating oil absorbed by the sponge 21 to the surface of the ball 19 when it contacts the sponge 21 and the ball 19, thereby achieving a lubrication effect.
