[0004] In the above technical solution, processing is carried out by controlling the heating device, the stirring drive device, the blast device, and the gas control structure. During the production process, some low-boiling organic compounds will evaporate to form waste gas, and particulate raw materials will be thrown out during the stirring process. The waste gas with a large amount of heat will carry the particulate raw materials and rise. However, since there is no device capable of treating waste gas in this reactor, the waste gas can only be directly discharged, which will cause harm to the environment and human health. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a waste gas treatment device for a container-type asphalt reactor, aiming to complete the treatment of waste gas by the cooperation of a filtering mechanism and a waste gas treatment mechanism.

[0006] According to the first aspect of the utility model, a waste gas treatment device for a container-type asphalt reactor is provided, which includes a movable reaction container, a filtering mechanism, a pipeline, and a waste gas treatment mechanism. A stirring chamber is arranged in the reaction container, and a first through hole communicating with the stirring chamber is arranged at the top of the reaction container;

[0007] The filtering mechanism includes a mounting base, a collection box, and a filter plate. The mounting base covers the first through-hole. The collection box is provided with an inlet and an outlet. The inlet is communicated with the mounting base, the outlet is communicated with the pipeline, and the pipeline is communicated with the waste gas treatment mechanism. The filter plate is located in the collection box and blocks between the inlet and the outlet to filter large particulate materials in the waste gas.

[0008] One of the technical solutions in the above technical solutions of the present utility model has at least one of the following advantages or beneficial effects:

[0009] In the present utility model, by covering the mounting base of the filtering mechanism on the first through-hole at the top of the reaction container, the waste gas will enter the mounting base after flowing out of the first through-hole, and then enter the collection box from the inlet of the collection box. Before the waste gas enters the pipeline, the filter plate will block the large particulate materials, leaving the large particulate materials in the collection box. The waste gas passing through the filter plate will flow out of the pipeline and then be treated in the waste gas treatment mechanism, which can not only prevent the accumulation of large particulate raw materials in the pipeline, but also reduce the harm of waste gas to the environment and human health.

[0020] The following disclosure provides many different implementation modes or examples for implementing different solutions of the present utility model.

[0021] Referring to Figures 1 to 6 As shown, in an embodiment of the present utility model, a container-type asphalt reactor exhaust gas treatment device includes a movable reaction container 1, a filtration mechanism 3, a pipe 4, and an exhaust gas treatment mechanism 2. A stirring chamber is provided in the reaction container 1, and a first through hole (not shown in the figure) communicating with the stirring chamber (not shown in the figure) is provided at the top of the reaction container 1;

[0022] The filtration mechanism 3 includes a mounting seat 31, a collection box 32, and a filter plate 33 covering the first through hole. An inlet 321 and an outlet 322 are provided on the collection box 32. The inlet 321 communicates with the mounting seat 31, the outlet 322 communicates with the pipe 4, the pipe 4 communicates with the exhaust gas treatment mechanism 2, and the filter plate 33 is located in the collection box 32 and blocks between the inlet 321 and the outlet 322 to filter large particulate materials in the exhaust gas;

[0023] During use: The exhaust gas generated in the stirring chamber of the reaction container 1 first enters the mounting seat 31 of the filtration mechanism 3 through the first through hole, then the exhaust gas moves towards the inlet 321 of the collection box 32 and enters the collection box 32. Then the exhaust gas will first pass through the filter plate 33 and be filtered by the filter plate 33 to block the large particulate raw materials in the exhaust gas. The large particulate raw materials will remain in the collection box 32. After passing through the filter plate 33, the exhaust gas exits from the outlet 322 and then enters the pipe 4. After that, it flows out of the pipe 4 and then enters the exhaust gas treatment mechanism 2 for exhaust gas treatment; In this way, it can not only prevent large particulate raw materials from accumulating in the pipe 4, but also reduce the harm of exhaust gas to the environment and human health.

[0024] For the specific structure of the reaction container 1, reference can be made to Patent CN202121612044.1, which will not be elaborated in this embodiment.

[0025] In this embodiment, a socket 323 is provided at the top of the collection box 32, and the filter plate 33 is inserted into the collection box 32 through the socket 323; by inserting the filter plate 33 into the collection box 32 through the socket 323, it is convenient for workers to replace and maintain the filter plate 33.

[0026] Preferably, the filter plate 33 includes a cover plate 331, a connecting plate 332, a bottom plate 333 and two side plates 334. The connecting plate 332 is rectangular, and the cover plate 331, the bottom plate 333 and the side plates 334 are respectively arranged on the four sides of the connecting plate 332 to enclose a chamber 336 on the connecting plate 332. A filter cotton (not shown in the figure) is detachably installed in the chamber 336;

[0027] The cover plate 331 and the bottom plate 333 are arranged oppositely, and a plurality of second through holes 3321 are provided on the connecting plate 332. The cover plate 331 can cover the socket 323;

[0028] Specifically, the filter cotton is installed in the chamber 336 formed by the cooperation of the cover plate 331, the bottom plate 333 and the side plates 334. Then, after the connecting plate 332 is inserted into the collection box 32 through the socket 323, the cover plate 331 will cover the socket 323, reducing the outflow of waste gas from the socket 323. When the waste gas enters the collection box 32 from the inlet 321, the waste gas will first pass through the second through holes 3321, then pass through the filter cotton, and the large particle raw materials will be blocked by the filter cotton, so that before the waste gas enters the pipeline 4 from the outlet 322, the large particle raw materials have been filtered out, avoiding the accumulation of large particle raw materials in the pipeline 4.

[0029] Preferably, the side plate 334 includes a connecting section 3341 and a limiting section 3342. The connecting section 3341 and the limiting section 3342 form an L-shaped structure. The connecting section 3341 is connected to the connecting plate 332, and the limiting section 3342 is opposite to the connecting plate 332.

[0030] Specifically, the connecting section 3341 is connected to the connecting plate 332, playing a role of support and fixation, while the limiting section 3342 is opposite to the connecting plate 332. Its main function is to fix the filter cotton in the chamber 336 when the filter cotton is installed, avoiding the displacement of the filter cotton and ensuring that the filter cotton can be set in the specified position.

[0031] In this embodiment, the bottom plate 333 and the connecting plate 332 are connected by a spring hinge 335 to press the filter cotton in the chamber 336;

[0032] Specifically, first flip the bottom plate 333 so that the bottom plate 333 is in a vertical state, making the bottom of the chamber 336 open. Then insert the filter cotton from the bottom. The side plate 334 will play a guiding role when the filter cotton is inserted. After the filter cotton is completely inserted into the chamber 336, release the bottom plate 333 and use the spring hinge 335 to reset the bottom plate 333. In this way, the filter cotton will be pressed in the chamber 336, thus completing the installation of the filter cotton. Then insert the connecting plate 332 into the collection box 32 from the socket 323. When the filter cotton needs to be replaced, flip the bottom plate 333 again to open the bottom of the chamber 336. Then draw out the filter cotton and insert another filter cotton into the chamber 336 from the bottom, making it more convenient to replace the filter cotton.

[0033] Preferably, a handle 337 is provided at the top of the filter plate 33; the handle 337 is of a U-shaped structure;

[0034] Furthermore, when the filter plate 33 needs to be disassembled, the worker can hold the handle 337 by hand and pull out the filter plate 33 upwards, which improves the convenience of replacement and maintenance. Moreover, the U-shaped handle 337 can better disperse the pressure, facilitating the operation of the worker.

[0035] Preferably, the cover plate 331 and the collection box 32 are connected by bolts 6; by using bolts 6 to fix the cover plate 331 on the collection box 32, the tightness between the cover plate 331 and the collection box 32 can be improved, reducing the outflow of waste gas from the socket 323 and preventing the displacement of the filter plate 33.

[0036] In this embodiment, a clamp 5 is further included. A connector 324 is provided at the outlet 322, and the pipeline 4 is detachably connected to the connector 324 through the clamp 5; when the collection box 32 needs to be cleaned, the worker first draws out the filter plate 33 from the collection box 32, and then only needs to loosen the clamp 5 and disassemble the pipeline 4 to clean the collection box 32.

[0037] Preferably, the waste gas treatment mechanism 2 includes an activated carbon adsorption box 21, a blower 22, and a combustion box 23. The activated carbon adsorption box 21, the blower 22, and the combustion box 23 are sequentially connected through the pipeline 4;

[0038] Furthermore, the blower 22 guides the flow of the waste gas. After the waste gas is first introduced into the activated carbon adsorption box 21 for preliminary waste gas treatment, it is then burned in the combustion box 23 to reduce the harmful gases generated during combustion and avoid polluting the environment.
