Description

Technical Field

[0001] The utility model relates to the technical field of waterborne acrylic emulsion production, in particular to an exhaust gas emission treatment device for waterborne acrylic emulsion production. Background Art

[0002] Waterborne acrylic emulsion, also known as waterborne acrylic resin emulsion, is an important type of chemical raw material, mainly copolymerized from pure acrylate monomers. It is non-toxic and pollution-free, with a milky white or nearly transparent viscous liquid appearance, and has many excellent properties such as water resistance, weather resistance, alkali resistance, stain resistance, corrosion resistance, film-forming property, adhesiveness, etc. These properties make waterborne acrylic emulsion widely used in many fields.

[0003] During the production of waterborne acrylic emulsion, exhaust gas needs to be discharged. After the exhaust gas is treated, it can be discharged. However, in the existing discharge process, when the filter screen is blocked, the filter screen needs to be removed, and then the machine needs to be stopped and disassembled, greatly reducing the work efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the existing technology that when the filter screen is blocked during the discharge process, the filter screen needs to be removed, and then the machine needs to be stopped and disassembled, greatly reducing the work efficiency, and to propose an exhaust gas emission treatment device for waterborne acrylic emulsion production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An exhaust gas emission treatment device for waterborne acrylic emulsion production, including a filtration box, one side of the top of the filtration box is fixedly communicated with an air inlet pipe, one side of the filtration box is provided with a communicated air outlet pipe, one side inner wall of the filtration box is fixedly connected with a fixing plate, the top and bottom of the fixing plate are both slidably connected with a storage box, and a filtration component for filtering the exhaust gas is arranged inside the storage box;

[0007] A switching component for switching the filtration component is arranged inside the filtration box, and the switching component is arranged on one side of the fixing plate;

[0008] A treatment component for treating the exhaust gas is arranged inside the filtration box.

[0009] In a possible design, the filtration component includes a cover plate arranged inside the storage box, a plurality of strip-shaped grooves are opened on one side of the cover plate, a rectangular frame is clamped inside the strip-shaped grooves, a filter screen is arranged inside the rectangular frame, a handle is fixedly connected to one side of the cover plate, a through hole matched with the cover plate is opened on one side of the filtration box, and one side of the cover plate extends to the outside of the filtration box.

[0010] In a possible design, the switching component includes the same baffle plate slidably connected between the inner walls on both sides of the filtering box. A lead screw rotatably penetrates through the top of the filtering box, the lead screw threadedly penetrates through the baffle plate, and a hand wheel is fixedly connected to the top of the lead screw.

[0011] In a possible design, the processing component includes a second partition plate fixedly connected to the inner wall of the top of the filtering box, a first partition plate fixedly connected to the inner wall of the bottom of the filtering box, an inclined plate fixedly connected to the inner wall of the bottom of the filtering box. The inclined plate is located below the second partition plate and on one side of the first partition plate. A drain pipe is fixedly communicated with the bottom of the filtering box. The drain pipe is used in cooperation with the inclined plate, and a valve is arranged on the drain pipe.

[0012] In a possible design, a notch is formed on one side of the top of the storage box, and a second fixing block is fixedly connected to one side of the inner wall of the bottom of the notch.

[0013] In a possible design, a first fixing block is fixedly connected to one side of one of the filter meshes. A groove is formed on one side of the first fixing block. A convex block slidably penetrates through the inside of the groove. A same spring is fixedly connected between one end of the convex block and one side inner wall of the groove. A side block is fixedly connected to one side of the convex block. One side of the convex block abuts against the second fixing block. The side block is located above the second fixing block, and one end of the side block abuts against the inner wall of one side of the filtering box.

[0014] In a possible design, two symmetrically arranged sliding grooves are formed at the bottom and top of the fixing plate. Sliding blocks are slidably connected to the inside of the sliding grooves, and the sliding blocks are fixedly connected to the corresponding storage box.

[0015] In this application, during use, the waste gas enters the inside of the filtering box through the air inlet pipe. There is a chemical solution on one side of the first partition plate, which can react with the waste gas. The reacted waste gas moves from below the second partition plate, passes above the first partition plate and then moves to the other side of the first partition plate. At this time, after being filtered by a plurality of filter meshes not blocked by the baffle plate, it is discharged through the air outlet pipe.

[0016] When it is necessary to replace the filter mesh, the hand wheel can be rotated.

At this time, the baffle plate can push the convex block to retract, and the convex block squeezes the spring into the inside of the groove. Then the convex block drives the side block to move horizontally, and the side block no longer abuts against the inner wall of the filtering box.

[0017] At this time, the handle can be pulled horizontally, and the handle drives the cover plate to move horizontally. Since the first fixed block is located inside the notch at this time, the storage box can be pulled to move horizontally. The storage box drives the slider to slide inside the chute. When the storage box cannot move, the filter screen moves to the outside of the filter box at this time. The cover plate can be moved vertically upward, and the cover plate drives multiple filter screens to move upward, which is convenient for taking out the filter screen. Furthermore, the replacement of the filter screen can be facilitated, without the need to stop the machine, improving work efficiency.

[0019] In the present utility model, for the waste gas emission treatment device for the production of waterborne acrylic emulsion, through the filtering assembly, the effect of filtering the waste gas can be achieved. Not only can the chemical liquid react with the waste gas, but also the impurities in the waste gas can be filtered by the filter screen.

[0020] In the present utility model, for the waste gas emission treatment device for the production of waterborne acrylic emulsion, through the switching assembly, the effect of switching the filtering assembly can be achieved, and thus the filtering position can be changed, which is convenient for replacing the filter screen without stopping the machine.

[0021] In the present utility model, the waste gas enters the interior of the filter box through the air inlet pipe. After being filtered by multiple filter screens not blocked by the baffle, it is discharged through the air outlet pipe. By rotating the handwheel, the position of the baffle is adjusted to switch the usage of multiple filter screens. Furthermore, multiple filter screens can be pulled out. After the storage box moves into place, multiple filter screens can be taken out vertically upward at this time, which is convenient for quickly replacing the filter screen without the need to stop the machine, improving work efficiency.
