[0009] In an embodiment of the utility model, the first protective silk screen and the second protective silk screen are attached to the filter silk screen and are bent synchronously with the filter silk screen.

[0010] The first protective wire mesh and the second protective wire mesh support the shape of the filter wire mesh, avoid deformation of the filter wire mesh during work, and thus enhance the stability of the filter.

[0011] In an embodiment of the utility model, the wire thickness of the first protective wire mesh and the second protective wire mesh is greater than the wire thickness of the filter wire mesh.

[0012] The first protective wire mesh and the second protective wire mesh have greater strength than the filter wire mesh, so that the first protective wire mesh and the second protective wire mesh protect the filter wire mesh from the outside.

[0013] In an embodiment of the utility model, the first protective wire mesh has a mesh count of 50-70, the second protective wire mesh has a mesh count of 70-80, and the filter wire mesh has a mesh count of 110-180.

[0014] The greater the mesh count of the metal mesh and the thinner the wire, the greater the filtering effect of the metal mesh with a greater mesh count arranged in the middle, and the protection of the metal mesh with high strength on both sides on the middle layer, so that the filter has both filtering effect and strength.

[0015] In an embodiment of the utility model, the fixed frame is further used to seal and fix the first protective wire mesh, the second protective wire mesh, and the filter wire mesh.

[0016] The fixed frame seals and supports the edges to improve the strength.

[0017] In an embodiment of the utility model, the fixed frame includes an inner frame and an outer frame, the inner frame is fixed with the first protective wire mesh, the second protective wire mesh, and the filter wire mesh, and the outer frame is fixed to the filter.

[0018] When the flower mesh needs to be replaced, the inner frame can be disassembled by rotating the clamping ring into the accommodation slot, and the replacement can be completed by rotating and placing the new flower mesh, so that the replacement is fast and convenient, and the utility model is more convenient to use.

[0019] As described above, the utility model has the following beneficial effects:

[0020] The thickness of the filtering wire screen with the bending wrinkles is obviously increased, the molten body needs a longer time when passing through the filtering wire screen, and the filtering wire screen has obvious wave peaks and wave troughs after the bending wrinkles, the molten body at the same position can pass through the wave trough after passing through the wave peak, the contact frequency of the molten body and the filtering wire screen is increased, so that the filtering effect of the single-layer flower net is improved by prolonging the contact time and increasing the contact frequency of the filtering wire screen and the molten body, the number of the flower nets required for the same filtering effect is reduced, the flower net is more convenient to use and replace.
