Description

Technical Field

[0001] The utility model relates to the technical field of acetate processing, in particular to an acetate waste residue filtering device. Background Art

[0002] Acetate esters are acetate ester products, which are widely used in the fields of solvents, plasticizers, surfactants and polymer monomers. In recent years, the domestic coating industry is gradually stopping the use of high-VOC solvents such as methyl ethyl ketone and methyl isobutyl ketone according to environmental protection requirements, while acetate esters are environmentally friendly solvents. Acetate ester products mainly refer to ethyl acetate and butyl acetate. They use renewable catalysts to directly add esterification of lower olefins such as propylene, 1-butene, 2-butene, and isobutylene with acetic acid or other carboxylic acids to produce corresponding isopropyl acetate, sec-butyl acetate, isobutyl acetate and other acetate esters and other carboxylic acid esters. Before processing acetate esters, some acetate ester raw materials will condense into solid agglomerates inside after being left to stand for a long time, so it is necessary to filter the solid agglomerate residues in the acetate esters.

[0003] After searching, a utility model with Chinese patent publication number CN217043414U discloses a filtering device for acetate residue, including a bracket, a support arm is provided on the outer surface of the upper end of the bracket, a vibration screening device for improving the filtering efficiency of acetate residue is provided between the support arms, the vibration screening device includes a storage barrel and a telescopic spring, a residue discharge pipe is provided in the middle part of the inner surface of the lower end of the storage barrel, a vibration motor is provided on the outer surface of the lower end of the storage barrel, a No. 1 spring fixing seat is provided between one end of the telescopic spring and the outer surface of the storage barrel, and a No. 2 spring fixing seat is provided between the other end of the telescopic spring and the support arm.

[0004] The above-mentioned device achieves the purpose of filtering acetate residue through a vibrating screening device. However, the residue intercepted by the filter will clog the mesh of the filter, affecting the filtering efficiency, and the clogged residue will increase with the use time. If the filter is frequently disassembled, the processing efficiency will also be affected. There is room for improvement. Therefore, an acetate waste residue filtering device is proposed.

[0015] Pour acetate into the water flow frame, and the acetate will flow downward along the opening at the bottom. At the same time, the cylinder is controlled to reciprocate and extend, and the acetate flow will continue to change, ensuring that the bottom filter frame can be utilized to the maximum extent.

[0016] As a further preferred embodiment of the present technical solution, a support column is fixedly mounted on the bottom of the outer wall at both ends of the box body, and a universal wheel is fixedly mounted on the outer wall at the bottom of multiple support columns.

[0018] As a further preferred embodiment of the present technical solution, the inner wall at the bottom of the water flow frame is arranged as an inclined surface, and the water outlet position of the water flow frame is at the bottommost position of the inclined surface. When the acetate falls into the water flow frame, it will slide along the inclined surface, thereby preventing part of the acetate from staying in the water flow frame.

The gears can drive the brushes to swing back and forth through the incomplete gear rings meshing with them. The brushes can also sweep the intercepted lumps to one side, and then slide down along the slope of the edge of the filter frame.

[0021] (2) The utility model provides a collection component, and the agglomerates will fall into the collection frame and be collected together, which is convenient for later processing.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, an acetate waste slag filtering device includes a box body 1, which is characterized in that: a filter assembly 6 is installed on the top of the box body 1, and the filter assembly 6 includes a filter frame 601 fixedly installed on the top of the box body 1, a support plate 602 fixedly installed on one side of the top outer wall of the filter frame 601, and a brush 603 is rotatably connected to the top of the support plate 602. The moving trajectory of the brush 603 is in contact with the inner surface of the filter frame 601, and the bristles of the brush 603 are in contact with the circumferential inner wall and the inner walls at both ends of the filter frame 601, and an incomplete tooth ring 604 is fixedly connected to one end of the top of the brush 603.

[0029] A forward and reverse motor 605 is fixedly mounted on the outer wall of the top of the support plate 602 . A gear 606 is coaxially fixed to the rotating shaft of the forward and reverse motor 605 . The gear 606 meshes with the incomplete gear ring 604 .

[0030] When acetate falls into the filter frame 601, the lumps will be intercepted, and then the forward and reverse motor 605 on the top of the support plate 602 will be started. The forward and reverse motor 605 will drive the gear 606 to rotate forward one circle and then reverse one circle. The gear 606 can drive the brush 603 to swing back and forth through the incomplete gear ring 604 meshing with it. The brush 603 can also sweep the intercepted lumps to one side, and then slide down along the slope of the edge of the filter frame 601.

[0031] like Figure 1As shown, an inclined plate is provided on both sides of the filter frame 601, and the two inclined plates are symmetrically arranged. When the agglomerate is at the top of the filter frame 601, it will slide down directly along the slope of the inclined plate, so that the agglomerate will not stay at the edge of the filter frame 601, eliminating the need for subsequent cleaning work.

[0032] like Figure 2 and Figure 4 As shown, a collecting assembly 7 is installed on both sides of the box body 1. The collecting assembly 7 includes a limiting groove 701 opened on the outer wall of one side of the box body 1. A collecting frame 702 is slidably connected in the limiting groove 701, and a filter screen 703 is fixedly installed inside the collecting frame 702.

[0033] A collecting hood 704 is fixedly installed on the outer wall of one side of the box body 1, and the collecting hood 704 is fitted with the lower surface of the collecting frame 702. A pipe 705 is fixedly inserted into the outer wall of the bottom of the collecting hood 704. One end of the pipe 705 is fixedly inserted into the box body 1. The part of the pipe 705 inserted into the box body 1 is tilted downward, which can prevent the acetate filtered by the filter frame 601 from flowing back into the pipe 705.

[0034] The agglomerates will fall into the collection frame 702 and be collected together for later processing. The acetate remaining in the agglomerates will also flow through the holes of the filter 703 to the collection cover 704 below, and finally flow through the pipe 705 to the bottom of the box 1 again, avoiding waste of resources.

[0035] like Figure 1 and Figure 2 As shown, a mounting frame is fixedly connected to the top of the outer wall at one end of the box body 1, and a horizontally arranged cylinder 4 is fixedly installed on the outer wall at the top of the mounting frame, and a water flow frame 5 is fixedly connected to the output end of the cylinder 4, and the water outlet of the water flow frame 5 is located at the top position of the filter frame 601. Acetate is poured into the water flow frame 5, and the acetate will flow downward along the opening at the bottom thereof. At the same time, the cylinder 4 is controlled to reciprocate and extend, and the acetate flow will also continue to change, ensuring that the bottom filter frame 601 can be utilized to the maximum extent.

[0036] like Figure 1 and Figure 2 As shown, a support column 2 is fixedly installed at the bottom of the outer wall at both ends of the box body 1, and a universal wheel 3 is fixedly installed on the outer wall at the bottom of multiple support columns 2. Only when the universal wheel 3 is in contact with the ground, the friction between the device and the ground can be ensured to be small enough, making the device more convenient to move.

[0037] like Figure 1 and Figure 2 As shown, the inner wall at the bottom of the water flow frame 5 is arranged as an inclined surface, and the water outlet position of the water flow frame 5 is at the bottommost position of the inclined surface.

[0038] When the acetate falls into the water flow frame, it will slide down along the inclined surface, thereby preventing part of the acetate from remaining in the water flow frame.

[0039] The utility model provides an acetate waste residue filtering device, and the specific working principle is as follows:

[0040] When the device is working, acetate is poured into the water flow frame 5, and the acetate will flow downward along the opening at the bottom thereof. At the same time, the cylinder 4 is controlled to reciprocate and expand, and the acetate flow will also change continuously, ensuring that the bottom filter frame 601 can be utilized to the maximum extent. When the acetate falls into the filter frame 601, the agglomerates will be intercepted, and then the forward and reverse motor 605 on the top of the support plate 602 is started. The forward and reverse motor 605 will drive the gear 606 to rotate forward one circle and then reverse one circle. The gear 606 meshes with the gear 606 to rotate forward one circle and then reverse one circle. The incomplete toothed ring 604 can drive the brush 603 to swing back and forth, and the brush 603 can also sweep the intercepted lumps to one side, and then slide down along the slope of the edge of the filter frame 601. These lumps will then fall into the collection frame 702 and be collected together for later processing. The residual acetate in the lumps will also flow through the holes in the filter screen 703 to the collection cover 704 below, and finally flow along the pipe 705 to the bottom of the box 1 again, avoiding waste of resources.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
