Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The pre-filter shown includes a lower frame 100 and an upper frame 103. A stepped through groove 101 is provided inside the lower frame 100. A through slot 104 is provided inside the upper frame 103. A protective net 108 is installed on the stepped through channel 101. The protective netting 108 has fixing plates 102 on both ends. The surface of the protective net 108 is covered with a filter section 105; The protective net 108 and the filter section 105 are stacked in the stepped channel 101. The lower frame 100 and the upper frame 103 are fixedly connected. The fixing plate 102 and the protective net 108 are integrally formed, such as stainless steel.

[0020] The working principle or structural principle is as follows: ① Place the fixing plate 102 and the protective net 108 in the stepped through groove 101; ② The filter part 105 is covered on the surface of the protective net 108, and the four sides of the filter part 105 protrude from the four sides of the protective net 108 respectively; ③ Connect the four end faces of the lower frame 100 and the upper frame 103 (using a movable connection method).

[0021] After a period of use, the filter 105 will need to be replaced. Separate the lower frame 100 and the upper frame 103, and remove the filter 105 for replacement. At the same time, the fixing plate 102 and the protective net 108 can be removed, and the surface of the protective net 108 can be cleaned.

[0022] In addition, the protective net 108 is preferably a double-sided powder-coated wire mesh or a double-sided galvanized wire mesh (selected according to the application scenario), which has the characteristics of being durable, not easily deformed and having a long service life.

[0023] In addition, the filter section 105 is preferably any one of non-woven fabric, nylon filter, metal filter, and activated carbon filter, selected according to the application scenario, to meet the filtration requirements for dust particles larger than 1µm (the mesh size of the filter is selected as needed).

[0024] In addition, preferably the size of the filter section 105 is larger than the size of the through groove 104 and the size of the protective net 108, to ensure thorough and seamless filtration and achieve stable filtration.

[0025] Example 2: Based on Example 1, the primary plate filter further includes screw holes 106 disposed in the four corner end faces of the stepped through groove 101, fixing plate through holes 107 disposed in the four corners of the fixing plate 102, and first bolts 109 for fixing the lower frame 100 and the fixing plate 102 through the fixing plate through holes 107 and screw holes 106.

[0026] Through the above structural design, the fixing plate 102 and the protective net 108 are firmly fixed in the lower frame 100 after the overall assembly, without moving and squeezing the filter part 105, so that the filter part 105 maintains the optimal filtration state; in addition, disassembly and assembly are also convenient.

[0027] Example 3: Based on Example 1 or Example 2, the primary plate filter further includes a second screw groove 110 disposed in the four corner end faces of the lower frame 100, a countersunk screw hole 111 disposed in the four corner end faces of the upper frame 103, and a second bolt 112 for fixing the lower frame 100 and the upper frame 103 through the countersunk screw hole 111 and the second screw groove 110.

[0028] Through the above structural design, the lower frame 100 and the upper frame 103 can be easily disassembled, making it convenient to replace the filter 105. After replacement, it is also easy to reassemble, thus improving the replacement efficiency of the filter 105.

[0029] Example 4: Based on Example 1, Example 2 or Example 3, the primary plate filter further includes a clamping part 113 disposed on one side of the upper frame 103 and used in conjunction with the filter part 105; wherein, the clamping part 113 is tightly attached to the surface of the filter part 105 and is used to limit and fix the filter part 105, ensuring that the other side of the filter part 105 is tightly attached to the surface of the protective net 108 to prevent gaps from appearing.

[0030] In addition, the clamping part 113 is preferably set to a wave shape, which does not affect the air outlet after filtration (does not block the wind) and ensures that the whole process achieves efficient filtration.

[0031] This type of primary plate filter is suitable for use in filtration systems or equipment in fresh air systems, pharmaceuticals, coating, semiconductors, large-scale farms, cleanrooms, etc.
