[0033] Specifically, refer to Figure 4 and Figure 5 The filter element is composed of a filter skeleton 114 and a filter cloth 115. The bottom of the lower connecting plate 110 is connected to the filter skeleton 114. The filter skeleton 114 plays a supporting role. The filter skeleton 114 adopts a plum blossom-shaped skeleton made of PP material. Filtering is performed through the filter cloth 115 on the outer ring surface. The outside of the filter skeleton 114 is provided with a filter cloth 115. Preferably, the filter cloth 115 is in the form of PP filter cloth 115. The bottom of the filter skeleton 114 is connected to a bottom cover 116. The bottom of the bottom cover 116 is connected to a strip plate 117. The strip plate 117 is used to fix multiple filter elements. The filter skeleton 114 is plum blossom-shaped.

[0034] Specifically, refer to Figure 1 A supporting leg 118 is connected to the middle of the outer wall of the tank body 101, and the supporting leg 118 is used to fix the tank body 101 to other devices or supporting structures. A slag discharge port 119 is provided at the bottom of the tank body 101, and the slag discharge port 119 is used for waste discharge.

[0040] In this embodiment, the liquid raw material is added into the tank body 101 through the material inlet 130. The raw liquid is filtered by the filter cloth 115 and then enters the flow pipe 105 through the connecting pipe 107, and is then discharged from the discharge pipe 103. The impurities in the raw material will be intercepted by the filter cloth 115, and then a filter cake will be formed on the filter cloth 115. When a single filter element needs to be replaced, the bolt 134 at the bottom of the strip plate 117 is first removed, and then the locking cover 113 is rotated upward, so that the entire filter element can be removed from both sides of the sliding groove 132 and then replaced.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
