Description

Technical Field

[0001] The utility model relates to the technical field of asphalt tank tail gas treatment devices, in particular to an asphalt tank tail gas treatment device for producing asphalt. Background Art

[0002] The exhaust gas generated during the asphalt production process needs to be treated by a treatment device. The existing exhaust gas treatment devices are mostly treatment tanks. However, the exhaust gas generated by asphalt production not only has complex components but also carries dust, which can easily cause the filter inside the exhaust gas treatment tank to be very dirty, and the filter is not easy to clean.

[0003] According to the description in an asphalt tank exhaust gas treatment device for producing asphalt disclosed on the patent website (authorization announcement number: CN215539295U), "The utility model discloses an asphalt tank exhaust gas treatment device for producing asphalt, including an exhaust gas treatment tank, one side of the exhaust gas treatment tank is fixedly connected to an air intake pipe, and a pretreatment device is provided in the middle of the air intake pipe. The pretreatment device includes a first connector, a second connector located on one side of the first connector, and a filter ring located between the first connector and the second connector. A convex ring is fixedly connected to one side of the first connector, and a first annular groove is provided on one side of the filter ring. The interior of the first annular groove is snap-connected with the outer surface of the convex ring, and multiple layers of filter screens are provided inside the filter ring. A second annular groove is provided on the outer surface of the second connector, and the second connector is sleeved with a fixed sleeve through the second annular groove. The interior of the fixed sleeve is provided with an internal thread. By setting the pretreatment device, it is convenient to pretreat the exhaust gas. At the same time, the filter screen inside the device is easy to disassemble, thereby facilitating cleaning."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can be used by engaging the convex ring with the first annular groove and then turning the handle to screw the fixed sleeve with the first connecting head. This design is convenient for pre-treatment of exhaust gas and prevents a large amount of dust from directly entering the exhaust gas treatment tank. At the same time, the filter ring is easy to disassemble, which makes it convenient to clean the multi-layer filter screen. However, the filter screen only intercepts the dust, and the dust will fall into the interior of the pre-treatment device, which is not easy to clean. The device needs to replace the filter plate frequently, affecting the working efficiency of the device. Therefore, it is necessary to improve an asphalt tank exhaust gas treatment device for producing asphalt to solve the above problems. Utility Model Content
