Technical Field
[0001] This application relates to the field of extrusion equipment technology, and specifically discloses a chemical production filtration extrusion device. Background Technology
[0002] In the production of chemical products, such as resins and adhesives, incompatible polymers and mechanical impurities need to be filtered out using different types of filter bags before packaging into drums. These filter bags are treated as hazardous waste after filtration, and the residue inside contains a small amount of incompatible small polymers and mechanical impurities, while 95% of the weight is chemical solvents. The solvents absorbed by these nylon and non-woven filter bags generate a large amount of hazardous waste. The cost of hazardous waste disposal is high, and the large number of filter bags piled up together poses a fire hazard during storage due to the high concentration of volatile organic solvents, especially in high-temperature seasons.

[0026] Example
[0027] To address the fire safety hazard posed by the large accumulation of filter bags during storage, particularly in high-temperature seasons, due to the high concentration of volatile organic solvents, in existing technologies, this paper references... Figure 1 and Figure 2 As shown, this application discloses a chemical production filter extrusion device for extruding organic solvents in a filter bag, which specifically includes a base 10, an upper pressure roller 20, a lower pressure roller 30, a transmission mechanism 40, and a liquid receiving tank 50.
[0028] The base 10 has a first U-shaped groove 11 inside; a first support platform 12 and a second support platform 13 are respectively provided on the front and rear sides of the first U-shaped groove 11.
[0029] The upper pressure roller 20 is adjustable in height and rotatably positioned above the first U-shaped groove 11 via the lifting adjustment unit 60, and the lower pressure roller 30 is rotatably positioned below the first U-shaped groove 11.
[0030] The transmission mechanism 40 includes a first transmission gear 42, a second transmission gear 43, a first drive gear 44, a second drive gear 45, and a rotary drive unit 41. The first transmission gear 42 and the second transmission gear 43 mesh with each other and are rotatably connected to the left outer wall of the base 10 via shafts (not shown). The first drive gear 44 and the second drive gear 45 are connected to the upper pressure roller 20 and the lower pressure roller 30 on the first outer wall of the base 10, respectively. The first drive gear 44 meshes with the first transmission gear 42, and the second drive gear 45 meshes with the second transmission gear 43. The rotary drive unit 41 is connected to the lower pressure roller 30 below the right outer wall of the base 10.
[0031] The liquid receiving tank 50 is located at the bottom of the lower pressure roller 30 and is fixed to the first support platform 12 and the second support platform 13;
[0032] In practice, the operator adjusts the gap between the upper pressure roller 20 and the lower pressure roller 30 in advance through the lifting adjustment unit 60. During this process, the first drive gear 44 moves upward and ensures that it continues to mesh with the first transmission gear 42. Then, the filter bag containing waste and organic solvent is pushed from the first support platform 12 into the gap between the upper pressure roller 20 and the lower pressure roller 30. Then, the rotation drive unit 41 is controlled to operate. At this time, the lower pressure roller 30 will drive the second drive gear 45 to rotate, the second drive gear 45 will drive the second transmission gear 43 to rotate, the second transmission gear 43 will drive the first transmission gear 42 to rotate, and the first transmission gear 42 will drive the first drive gear 44 to rotate, thereby causing the upper pressure roller 20 to start rotating. During this process, the upper pressure roller 20 and the lower pressure roller 30 rotate to squeeze the filter bag, and the squeezed organic solvent will flow into the liquid receiving tank 50 for recovery through the gap between the first support platform 12 and the second support platform 13.
[0033] To prevent organic solvents from flowing outward on the first support 12 and the second support 13, the first support 12 and the second support 13 are respectively installed at an angle on the front and rear sides of the base 10, and baffles 14 are respectively provided on the left and right sides of the first support 12 and the second support 13. When organic solvent drips from the filter bag to the first support 12 or the second support 13, it will flow into the liquid receiving tank 50 in the gap between the first support 12 and the second support 13 and be blocked by the baffles 14.
[0034] In one specific embodiment, the lifting adjustment unit 60 of this application includes two second U-shaped grooves 61 opened on the left and right side walls of the base 10, two sliders 62 respectively slidably disposed in the two second U-shaped grooves 61, two overlapping blocks 63 respectively disposed above the two second U-shaped grooves 61, and two hand crank screws 64 respectively passing through the two overlapping blocks 63 and connected to the two sliders 62. The upper pressure roller 20 is rotatably disposed between the two sliders 62. When the upper pressure roller 20 is driven to move upward, the operator operates the two hand crank screws 64 to rotate, so that the sliders 62 move up and down in the two second U-shaped grooves 61. At this time, the above-mentioned function is realized.
[0035] In one specific embodiment, the rotary drive unit 41 of this application is a geared drive motor. Under the drive of the geared drive motor, the lower pressure roller 30 cooperates to drive the upper pressure roller 20 to rotate at a low speed, thereby achieving better pressing of the filter bag and squeezing out the organic solvent in the filter bag.
[0036] To ensure the stable installation of the first transmission gear 42, the second transmission gear 43, and the first drive gear 44, this application connects the first transmission gear 42 and the second transmission gear 43 through a first connecting rod 46 (the first transmission gear 42 and the second transmission gear 43 can rotatably pass through the first connecting rod 46), and connects the first transmission gear 42 and the first drive gear 44 through a second connecting rod 47 (the first transmission gear 42 and the first drive gear 44 can rotatably pass through the second connecting rod 47). When the lifting adjustment unit 60 drives the upper pressure roller 20 to rise and fall, the first connecting rod 46 remains stationary, while the second connecting rod 47 can rotate in sync with the rise and fall of the upper pressure roller 20.
[0037] To facilitate the later recovery of organic solvent in the receiving tank 50, this application has installed a manual control valve (not shown) at the bottom of the receiving tank 50. In practice, the operator can open the manual control valve to allow the organic solvent to flow out.
[0038] In order to ensure that the liquid receiving tank 50 does not interfere with the lower pressure roller 30, this application also provides clearance grooves 51 on the left and right sides of the liquid receiving tank 50 to make way for the lower pressure roller 30, and when the rotary drive unit 41 drives the lower pressure roller 30 to rotate, it will not come into contact with the side wall of the clearance groove 51.
