Therefore, when replacing the filter, the operator needs to use auxiliary tools to disassemble the bolts one by one, which is time-consuming and laborious. Moreover, due to the acidic gas contained in the waste gas, it is easy to cause the bolts to rust, increasing the difficulty of disassembly. In view of this, this application proposes a ceramic filter for industrial waste gas filtration that is convenient to replace. Content of the Utility Model

[0023] The annular groove at the bottom of the clamp 6 can be quickly sleeved above the core body 1, and by adjusting the tension state of the clamp 6, the connection between the assembly seat 7 and the core body 1 can be quickly completed.

[0024] Among them, the supporting plate 8 is composed of a plurality of bottom plates arranged circumferentially, and the plurality of bottom plates are arranged at equal intervals. A circular plate is commonly connected to one end of the plurality of bottom plates away from the inner wall of the assembly seat 7.

[0025] By fixedly connecting the plurality of supporting plates 8 to the inner wall of the assembly seat 7, a better supporting effect can be provided for the components used for installation above, and the stability during the installation of the core body 1 can be improved.

The specific working principle is as follows: The annular seat 4 arranged at the bottom of the core body 1 is connected with the ventilation pipeline of the filtration equipment. The sealing ring 5 installed on the inner wall of the annular seat 4 can prevent waste gas from leaking during transportation. The core body 1 is connected with the assembly seat 7 through the annular groove opened at the bottom of the clamp 6. Turning the knob 10 drives the threaded rod 9 to rotate.
