[0030] It should be noted that the filtration of lyocell fiber solvent generally requires passing through multiple filters, mainly including coarse filters, precision filters and ultrafilters. The filtration equipment in this application is a coarse filter, which is mainly used to filter large particle impurities in the solvent. The solvent filtered by the coarse filter is then filtered through a precision filter and an ultrafilter in turn.

[0031] Furthermore, the filter tank 1 is suspended on the ground by a bracket, and the cylinder cover 10 is detachable, so that the filter screen cylinder 2 can be easily replaced or repaired.

[0032] The filter screen cylinder 2 is suspended inside the filter tank 1, and a filter plate 13 is provided inside the filter screen cylinder 2. A box body 15 is connected to the filter tank 1.

[0037] A slag discharge hopper 8 is provided inside the filter tank 1 , and the slag discharge hopper 8 is located below the filter screen cylinder 2 .

[0038] It should be noted that the slag bucket 8 described in this embodiment is a funnel structure, and one end of the slag bucket 8 extends to the outside of the filter tank 1 through a guide pipe, and a control valve is provided on the guide pipe. The slag bucket 8 can discharge the removed impurities and discharge the impurities and the filtered solvent from different paths, which can prevent the impurities from contaminating the drain pipe 12 again, thereby improving the efficiency of solvent filtration.

[0043] Furthermore, if Figure 4 As shown, the locking assembly 4 may include a limiting column 40, a locking column 41, an abutment plate 42 and a first spring 43, wherein the limiting column 40 is installed on the lower surface of the connecting seat 14, the upper surface of the gear ring 32 is provided with a first groove 320, the first spring 43 and the abutment plate 42 are both arranged inside the first groove 320, and the two ends of the first spring 43 are respectively connected to the bottom of the first groove 320 and the abutment plate 42, the interior of the first groove 320 is provided with a second groove 321 allowing the locking column 41 to pass through, and the locking column 41 is arranged on the side wall of the limiting column 40.

[0044] It should be noted that the second groove 321 described in this embodiment is connected to the first groove 320. When the limit column 40 is locked, the locking column 41 is located inside the second groove 321, and the first spring 43 is in a compressed state at this time, so that the locking column 41 can abut against the inner upper wall of the second groove 321, and finally the connecting seat 14 and the gear ring 32 are connected together, and the connecting seat 14 and the filter screen cylinder 2 are driven to rotate by driving the gear ring 32 to rotate.

[0045] Specifically, when the filter screen cartridge 2 needs to be removed, the relevant personnel presses the filter screen cartridge 2 downward and rotates the filter screen cartridge 2 to a certain angle. The filter screen cartridge 2 drives the limiting column 40 and the locking column 41 to rotate to a certain angle. When the locking column 41 rotates from the second groove 321 to the inside of the first groove 320, the locking column 41 can be unlocked.

[0046] In one embodiment of the present application, Figure 5 As shown, the first cleaning component 5 may include a vertical plate 50, a horizontal plate 51, a second spring 52, a first slider 53, a first support plate 54, a first brush plate 55 and a plurality of electromagnetic blocks 56, wherein the vertical plate 50 is embedded and installed on the inner wall of the filter tank 1, one end of the horizontal plate 51 is connected to the vertical plate 50, and a first slide groove 510 is provided on the lower surface of the horizontal plate 51, the second spring 52 is arranged in the first slide groove 510, and the second spring 52 is connected to the first slider 53, the first support plate 54 is installed on the lower surface of the first slider 53, the first brush plate 55 is arranged on a side of the first support plate 54 adjacent to the filter screen cylinder 2, and a plurality of electromagnetic blocks 56 are respectively arranged on the opposite surfaces of the first support plate 54 and the vertical plate 50.

[0047] It should be noted that the transverse plate 51 described in this embodiment can be connected to the vertical plate 50 via fasteners, wherein the fasteners can be bolts or screws, so as to facilitate the disassembly of the first cleaning component 5 .

[0048] Furthermore, the first slider 53 is slidably connected to the first slide groove 510, and the first support plate 54 is arranged inside the filter screen cylinder 2. When filtering the solvent, the first brush plate 55 does not contact the filter screen cylinder 2, and the second spring 52 is in a natural state.

[0049] In an embodiment of the present application, when the electromagnetic block 56 is energized, the electromagnetic block 56 can generate a magnetic attraction force, so that the electromagnetic blocks 56 on the first support plate 54 and the vertical plate 50 attract each other, so that the first support plate 54 and the first brush plate 55 move toward the direction of the vertical plate 50, and finally the first brush plate 55 abuts against the inner wall of the filter screen cylinder 2. At this time, the second spring 52 is in a compressed state.

[0050] In one embodiment of the present application, Figure 5 As shown, the second cleaning assembly 6 may include a third spring 60, a second slider 61, a second support plate 62 and a second brush plate 63, wherein a second slide groove 540 is provided on the first support plate 54, the third spring 60 is arranged in the second slide groove 540, the second slider 61 is connected to the end of the third spring 60, the second support plate 62 is arranged on the lower surface of the second slider 61, the second brush plate 63 is installed on the lower surface of the second support plate 62, and the second brush plate 63 abuts against the upper surface of the filter plate 13.

[0051] In the embodiment of the present application, the second brush plate 63 can remove impurities on the filter plate 13 to prevent the impurities from clogging the mesh, and by providing the third spring 60, the second brush plate 63 can always be in contact with the filter plate 13, thereby improving the impurity removal effect.

[0052] In one embodiment of the present application, Figure 6 As shown, the flip assembly 7 may include a support shaft 70, a second gear 71, a tooth plate 72 and a connecting plate 73, wherein the support shaft 70 is arranged to pass through the filter plate 13, and the two ends of the support shaft 70 are respectively rotatably connected to the filter screen cylinder 2, the second gear 71 is arranged on the support shaft 70, the tooth plate 72 is slidably arranged on the outer wall of the filter screen cylinder 2, and the tooth plate 72 is meshedly connected to the second gear 71, one end of the connecting plate 73 is connected to the tooth plate 72, and the other end of the connecting plate 73 is installed with a driving member.

[0053] It should be noted that the driving member described in this embodiment can be an electric push rod, which can drive the connecting plate 73 and the tooth plate 72 to move up and down, and through the cooperation of the second gear 71, drive the support shaft 70 and the filter plate 13 to flip 90 degrees, so that impurities on the filter plate 13 can fall off quickly.

[0054] In one embodiment of the present application, Figure 1 As shown, an equalizing plate 9 is provided inside the filter tank 1 , and the equalizing plate 9 is detachably arranged on the lower surface of the cylinder cover 10 .

[0055] It should be noted that the equalizing plate 9 described in this embodiment has a hemispherical structure and a plurality of mesh holes evenly distributed on the equalizing plate 9. The equalizing plate 9 can evenly disperse the solvent, reducing the impact force of the solvent on the filter mesh cylinder 2, so that the solvent can fall into the interior of the filter mesh cylinder 2 in a more dispersed manner, which is conducive to rapid filtration.

[0056] Furthermore, the mesh holes on the equalizing plate 9 can also perform a first filtration on the solvent. Since the equalizing plate 9 and the cylinder cover 10 are detachably connected, it is convenient to clean the impurities inside the equalizing plate 9.

[0057] Specifically, when filtering the solvent, the relevant personnel transport the solvent to the water inlet pipe 11 through a liquid pump, and the solvent enters the interior of the filter tank 1 through the water inlet pipe 11. After passing through the equalizing plate 9, the solvent can fall more evenly on the inside of the filter mesh cylinder 2, and impurities with larger particles will be trapped in the space formed by the filter mesh cylinder 2 and the filter plate 13.

[0058] When a lot of impurities are accumulated, it is easy to cause the filter cylinder 2 and the filter plate 13 to be blocked. At this time, the relevant personnel can energize the electromagnetic block 56 on the vertical plate 50 and the first support plate 54. The electromagnetic block 56 after energization generates magnetic attraction, so that the first support plate 54 moves toward the vertical plate 50, and finally the first brush plate 55 abuts against the inner wall of the filter cylinder 2, and the second brush plate 63 abuts against the upper surface of the filter plate 13. Then the relevant personnel can control the drive shaft 30 to rotate, and the drive shaft 30 drives the first gear 31 to rotate, and drives the filter cylinder 2 to rotate through the cooperation of the gear ring 32. During the rotation of the filter cylinder 2, the impurities inside the filter cylinder 2 and the filter plate 13 can be removed by the first brush plate 55 and the second brush plate 63, without removing the filter cylinder 2, and the operation is convenient.

[0059] Finally, the relevant personnel control the driving member to start, and the driving member drives the connecting plate 73 and the tooth plate 72 to move downward, and through the cooperation of the second gear 71 and the support shaft 70, drives the filter plate 13 to flip 180 degrees, so that the filter plate 13 is in a vertical state. At this time, the cleaned impurities will automatically fall into the inside of the slag discharge bucket 8 and be discharged through the guide pipe, thereby saving the time of removing the filter screen cylinder 2 and improving the efficiency of solvent filtration.

[0060] In summary, the lyocell fiber solvent filtering equipment of the embodiment of the present application can directly remove impurities on the filter mesh cylinder and the filter plate without removing the filter mesh cylinder, and quickly discharge the impurities. The operation is simple and quick, and the effect and efficiency of solvent filtration are significantly improved.
