Description

Technical Field

[0001] This utility model belongs to the field of papermaking technology, specifically relating to a filter device for processing defoamers that is easy to clean. Background Technology

[0002] In the processing of paper additives, the filtration device for defoamer processing plays an important role. It mainly removes large particulate impurities from the raw materials through filter media such as filter screens, ensuring the purity of the raw materials entering the subsequent processes, reducing unnecessary impurities, and thus improving the performance of the final product.

[0003] Some existing filtration devices are usually fixedly installed on the inner wall of the feed pipe, which may result in difficulty in cleaning after use. If impurities and residues on the filtration device are not thoroughly removed, these residues will gradually accumulate over time, clogging the filter media, thereby reducing filtration efficiency and affecting the filtration effect.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This embodiment of the present invention provides a filter device for defoamer processing that is easy to clean, which can achieve the effect of quickly disassembling the filter screen 202 and moving it to a suitable cleaning area for cleaning without the need for professional disassembly and assembly tools.

[0026] The processing mechanism 100 includes a mixing tank 101, a feed pipe 102 connected to the top of the mixing tank 101, and a discharge valve 103 connected to the bottom of the mixing tank 101.

[0027] It should be noted that the mixing tank 101 is used to hold the defoamer raw material, the feed pipe 102 is used to add the defoamer raw material into the mixing tank 101, and the discharge valve 103 can be opened to discharge the processed defoamer.

[0028] The disassembly and assembly mechanism 200 includes a movable tube 201 used in conjunction with the feed tube 102, a filter screen 202 fixedly installed on the inner wall of the movable tube 201 and used in conjunction with the feed tube 102, a fixed frame 203 fixedly connected to the outer surface of the movable tube 201, a first rotating shaft 204 fixedly installed on the inner wall of the fixed frame 203 by bearings, a ratchet clamp 205 fixedly sleeved on the outer surface of the first rotating shaft 204, a fixed disc 206 fixedly connected to the through end of the first rotating shaft 204, and a first torsion spring 207 sleeved on the outer surface of the first rotating shaft 204.

[0029] It should be noted that the specifications and dimensions of the movable tube 201 are the same as those of the feed tube 102. When the ratchet clamp 205 rotates to its maximum stroke, it can form a closed ring with the fixed frame 203, thereby firmly fixing the movable tube 201 and the filter screen 202 to the top of the feed tube 102.

[0030] Specifically, a rotating bearing sleeve is installed at the connection between the first rotating shaft 204 and the fixed frame 203, and a ratchet clamp 205 is located inside the fixed frame 203.

[0031] Furthermore, the bottom of the first torsion spring 207 is fixed to the outer surface of the fixed frame 203, and the top of the first torsion spring 207 is fixedly connected to the outer surface of the fixed plate 206.

[0032] Preferably, a limiting component 208 is disposed on the inner surface of the fixed frame 203 on the side away from the first rotating shaft 204 and used to limit the ratchet clamp 205, and an anti-slip pad 209 is fixedly connected to the inner side of the ratchet clamp 205 and used in conjunction with the feed pipe 102.

[0033] It should also be noted that the anti-slip pad 209 is made of polytetrafluoroethylene, which has good corrosion resistance to oils and solvents and can be used in a temperature range of -200℃ to 260℃.

[0034] It should be noted that the limiting component 208 includes a second rotating shaft 208a fixedly mounted on the inner wall of the fixed frame 203 away from the first rotating shaft 204 by a bearing, and a pawl 208b fixedly sleeved on the outer surface of the second rotating shaft 208a and used in conjunction with the ratchet clamp 205.

[0035] The outer side of the ratchet clamp 205 engages with the inner side of the pawl 208b. Rotating the second rotating shaft 208a can drive the pawl 208b to rotate to a position where it disengages from the ratchet clamp 205, thereby releasing the pawl 208b from limiting the ratchet clamp 205.

[0036] Furthermore, the limiting component 208 also includes a second turntable 208c fixedly connected to the through end of the second rotating shaft 208a, and a second torsion spring 208d sleeved on the outer surface of the second rotating shaft 208a.

[0037] Specifically, a rotating bearing sleeve is installed at the connection between the second rotating shaft 208a and the fixed frame 203, the bottom of the second torsion spring 208d is fixedly connected to the outer surface of the fixed frame 203, and the top of the second torsion spring 208d is fixedly connected to the outer surface of the second turntable 208c.

[0038] In use, rotating the second turntable 208c drives the second rotating shaft 208a and the pawl 208b to rotate synchronously, causing the pawl 208b to move to a position where it disengages from the ratchet clamp 205, thereby releasing the restriction on the ratchet clamp 205. The reaction force of the first torsion spring 207 drives the fixed plate 206, the first rotating shaft 204 and the ratchet clamp 205 to reset, releasing the restriction on the movable tube 201 and the filter screen 202. This allows the filter screen 202 to be quickly disassembled and moved to a suitable cleaning area for cleaning without the need for professional disassembly and assembly tools.

[0039] When reinstalling the filter screen 202 after cleaning: Place the movable tube 201 on top of the feed tube 102, rotate the ratchet clamp 205 to drive the first rotating shaft and the fixed plate 206 to rotate, causing the fixed plate 206 to drive the first torsion spring 207 to undergo elastic deformation. When the ratchet clamp 205 rotates to the position of contacting the pawl 208b, the ratchet clamp 205 squeezes the pawl 208b, causing the pawl 208b to drive the second rotating shaft 208a and the second rotating plate 208c to rotate synchronously. The rotation causes the second torsion spring 208d to undergo elastic deformation, driven by the second turntable 208c. The reaction force of the second torsion spring 208d then drives the second turntable 208c, the second rotating shaft 208a, and the pawl 208b to reset, so that the pawl 208b limits the ratchet clamp 205. When the ratchet clamp 205 rotates to its maximum stroke, it forms a closed ring with the fixed frame 203, thereby achieving the effect of firmly fixing the movable tube 201 and the filter screen 202 to the top of the feed tube 102.

[0040] In summary, through the cooperation between the various components in the disassembly and assembly mechanism 200, not only can the filter screen 202 be quickly disassembled and moved to a suitable cleaning area for cleaning without the need for professional disassembly and assembly tools, but it can also be quickly installed above the feed pipe 102 after the filter screen 202 has been cleaned, so as to ensure that the filter screen 202 is cleaned more thoroughly in a suitable cleaning area and avoid the accumulation of residues.
