[0006] Furthermore, the filter is assembled by fixedly connecting a bottom inlet assembly, an inlet header, a filter cavity, an outlet end cover and an outlet flange in sequence from bottom to top.

[0007] Furthermore, a filter element mounting plate is provided at the top of the filter cavity, and a plurality of filter elements are fixed on the filter element mounting plate.

[0008] As a preferred solution, a sealing ring is provided at the joint of the fixed connection assembly.

[0009] As a preferred solution, a stepped protrusion is provided at the joint to isolate the sealing ring and the liquid.

[0010] Furthermore, the interior of the heating jacket is a heating cavity for the heat medium to flow, a heat medium inlet is arranged at the bottom of the heating jacket, a heat medium outlet is arranged at the top, and an equipment base is arranged at the lower end of the heating jacket.

[0011] Furthermore, a through hole is provided in the center of the bottom of the heating jacket, and the bottom inlet assembly is arranged in the through hole.

[0012] As a preferred solution, a plurality of spoiler distribution plates are arranged inside the heating cavity.

[0013] The beneficial effects of the utility model are:

[0014] The utility model can easily separate the filter from the heating jacket through modular design, without large-scale disassembly or shutdown maintenance of the entire system, thus greatly reducing the labor intensity of workers and reducing the time and labor costs required for maintenance. In addition, this design also promotes the rapid replacement and upgrading of the filter element, ensures the continuous and stable operation of the production line, effectively avoids production losses caused by long-term shutdown maintenance, and further reduces the overall operating costs of the enterprise.
