Description

Technical Field

[0001] This patent relates to the technical field of filter press tanks, specifically a cellulose filter press tank. Background Art

[0002] Cellulose is a macromolecular polysaccharide composed of glucose, which is insoluble in water and general organic solvents. It is the main component of plant cell walls. In the processing and production process, cellulose is added to a filter press tank, covered with a filter screen, and gas is input into the upper half of the tank body to increase the pressure difference between the upper and lower sides, so that the water in the cellulose solution is filtered out from the lower side. The tank body of the existing filter press tank is mostly divided into an upper tank body and a lower tank body. When it is necessary to remove the cellulose on the filter screen, the upper tank body and the lower tank body need to be disassembled and then the cellulose on the filter screen needs to be removed. However, most of the tank bodies are large in size and weight. This operation method is not convenient for personnel to disassemble and assemble the tank body, which reduces production efficiency. For this reason, we propose a cellulose filter press tank. Summary of the invention

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 This patent provides a technical solution: a cellulose filter press tank, including a tank body 1, a steam pipe 2 is embedded in the left wall of the tank body 1, a feed pipe 3 and a pressure gauge 4 are embedded in the top of the tank body 1, a rectangular hole 5 is provided on the right wall of the tank body 1, a fixing ring 6 is fixedly installed on the inner wall of the tank body 1, a mounting ring 7 is provided on the top of the fixing ring 6, a filter screen 8 is fixedly installed on the inner wall of the mounting ring 7, a scraper 9 is attached to the left side of the top of the mounting ring 7, a cross bar 10 is fixedly installed on the top of the scraper 9, a sealing plate 11 is fixedly installed on the right end of the cross bar 10, and the front-to-back length of the sealing plate 11 is greater than the front-to-back length of the rectangular hole 5;

[0020] The front-to-back length of the scraper plate 9 is greater than the front-to-back length of the filter screen 8 , but matches the front-to-back length of the rectangular hole 5 .

[0021] A rubber pad 12 is fixedly installed on the left side of the sealing plate 11. Mounting holes 13 are provided at the four corners of the sealing plate 11. Bolts 14 are provided in the mounting holes 13. The left end of the bolt 14 is screwed into the outer right side wall of the tank body 1. The left side of the rubber pad 12 is tightly attached to the outer right side wall of the tank body 1.

[0022] An annular groove 15 is formed on the inner side wall of the mounting hole 13 , and an annular ring 16 is fixedly mounted on the side wall of the bolt 14 . The annular ring 16 is located in the annular groove 15 .

[0023] During production, the sealing plate 11 needs to be frequently disassembled to clean the cellulose on the filter screen 8. The circular ring 16 is arranged in the circular ring groove 15 to increase the integration of the bolt 14 and the sealing plate 11, so as to prevent the bolt 14 from being disassembled from the threaded groove on the right side wall of the tank body 1 and the bolt 14 from being separated from the mounting hole 13 and causing the loss of parts.

[0024] Specifically, the side wall of the bolt 14 does not contact the inner side wall of the mounting hole 13 .

[0025] Specifically, the outer diameter of the circular ring 16 matches the inner diameter of the circular ring groove 15 , and the outer side wall of the circular ring 16 is slidably mounted on the inner side wall of the circular ring groove 15 .

[0026] By preventing the side wall of the bolt 14 from contacting the inner wall of the mounting hole 13, friction caused by the threads on the side wall of the bolt 14 contacting the inner wall of the mounting hole 13 can be avoided, making it difficult to rotate the bolt 14 and avoiding wear on the threads. The outer wall of the ring 16 is slidably mounted on the inner wall of the annular groove 15 to limit the movement trajectory of the bolt 14, so that the bolt 14 moves left and right in the mounting hole 13, avoiding shaking of the bolt 14 in the mounting hole 13.

[0027] Specifically, the outer wall of the circular ring 16 is provided with a circular convex surface 17 , and the circular convex surface 17 is slidably mounted on the inner wall of the circular ring groove 15 .

[0028] The provision of the circular convex surface 17 can reduce the contact area between the outer wall of the circular ring 16 and the inner wall of the circular groove 15, reduce the contact damping, and increase the sliding property of the contact surface when the circular ring 16 moves left and right.

[0029] Specifically, the sealing plate 11 includes a first plate body 18 and a second plate body 19 , and the right side of the first plate body 18 is mounted on the left side of the second plate body 19 .

[0030] like Figure 4 As shown, by dividing the sealing plate 11 into a first plate body 18 and a second plate body 19 , the annular groove 15 can be divided into two parts, which is convenient for opening the annular groove 15 in the early stage and for installing the annular ring 16 in the annular groove 15 .

[0031] Specifically, a square hole 20 is provided in the middle of the second plate body 19, and a square column 21 is integrally formed in the middle of the right side surface of the first plate body 18. The side wall of the square column 21 is in relative contact with the inner wall of the square hole 20, and a stud 22 is integrally formed at the right end of the square column 21. The right end of the stud 22 passes through the square hole 20 and is screwed with a nut 23. The left side surface of the nut 23 is tightly fitted on the right side surface of the second plate body 19.

[0032] The above structure facilitates the assembly of the first plate body 18 and the second plate body 19. The side wall of the square column 21 is in relative contact with the inner wall of the square hole 20, so that the first plate body 18 and the second plate body 19 can only move left and right relative to each other during assembly. If the square column 21 and the stud 22 are an integral screw rod, then when the locking nut 23 is tightened, the second plate body 19 will rotate around the screw rod as the axis, which is not convenient for installation.

[0033] Working principle: Cellulose (such as wood cellulose) is fed into the filter screen 8 in the tank body 1 through the feed pipe 3, and the whole is injected into the tank body 1 through the steam pipe 2 to increase the pressure in the inner cavity of the tank body 1, so that the water in the cellulose is separated and enters the bottom of the tank body 1 through the filter screen 8. After the filtration is completed, the bolts 14 are removed, and the sealing plate 11 is moved to the right. The cellulose on the filter screen 8 is driven to move to the right through the rectangular hole 5 by the scraper 9. Compared with the traditional method of disassembling the tank body, it is more labor-saving and convenient, easy to operate, and improves work efficiency.

[0034] The moisture content of different wood celluloses is in the range of 5%-15%, so after the wood cellulose raw material is dehydrated, the height of the remaining cellulose cannot exceed the height of the scraper 9.

[0035] It should be noted that the equipment structure and drawings of this patent mainly describe the principles of this patent. In terms of the technology of this design principle, the settings of the device's power mechanism, power supply system and control system are not fully described.
