Technical Field
[0001] This utility model belongs to the field of filtration system application technology, specifically relating to a glass fiber high-temperature paint mist filter. Background Technology
[0002] Fiberglass high-temperature paint mist filters are mainly used in hot air high-temperature ovens in painting plants to filter tar, soot, dust and other particles generated in the high-temperature drying room to prevent damage to the paint quality of the surface of the items.
[0003] The frame of the high-temperature paint mist filter made of glass fiber is made of galvanized / aluminum frame and the filter media is glass fiber. It is made of long glass fibers stacked in a non-woven manner and fixed with aluminum expanded mesh. It is not easy to deform, can withstand high temperature of 300℃ and has good chemical resistance.
[0004] Currently, traditional high-temperature paint mist filters made of fiberglass are usually designed as a single unit and are fixed by welding during assembly. This makes it inconvenient to replace / repair the filter media during use, which restricts the practicality of the high-temperature paint mist filter and also indirectly increases the time required for replacement / repair.
[0005] Therefore, based on the above problems, this utility model provides a glass fiber high-temperature paint mist filter. Utility Model Content

[0022] Example 1
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The fiberglass high-temperature paint mist filter shown includes a metal frame 100.
[0024] The inner walls of both sides of the metal frame 100 are symmetrically provided with strip plates 101.
[0025] A set of upper horizontal U-shaped grooves 102 and a set of lower horizontal U-shaped grooves 103 are symmetrically arranged within the plane of symmetry of the strip plate 101.
[0026] The strip plate 101 has screw grooves 104 respectively provided in the same end face.
[0027] An upper metal filter 105 and a lower metal filter 109 are horizontally mounted inside the strip plate 101 via a set of upper horizontal U-shaped grooves 102 and a set of lower horizontal U-shaped grooves 103, respectively.
[0028] A pleated filter paper layer 110 (a conventional glass fiber pleated filter paper layer) is provided inside the cavity formed by the strip plate 101, the upper metal filter screen 105, and the lower metal filter screen 109.
[0029] A strip pressure plate 106 is provided inside the same end face formed by the metal frame 100 and the strip plate 101.
[0030] The two end faces of the strip pressure plate 106 are symmetrically provided with countersunk screw holes 107.
[0031] The strip plate 101 and the strip pressure plate 106 are fixed together by bolts 108 through the screw groove 104 and the countersunk screw hole 107.
[0032] The folded filter paper layer 110 has two sides that abut against the upper metal filter screen 105 and the lower metal filter screen 109, respectively, and the two sides of the folded filter paper layer 110 have two sides that abut against the opposite sides of the strip plate 101, respectively.
[0033] The working principle is as follows:
[0034] (1) Insert the upper metal filter 105 and the lower metal filter 109 into the opposite surfaces of the strip plate 101 through a set of upper horizontal U-shaped grooves 102 and a set of lower horizontal U-shaped grooves 103, respectively;
[0035] (2) Insert the folded filter paper layer 110 into the cavity formed by the upper metal filter screen 105, the lower metal filter screen 109, and a set of strip plates 101;
[0036] (3) Place the strip plate 106 in the same end face of the metal frame 100 and the strip plate 101, and use bolts 108 to fix the strip plate 101 and the strip plate 106 through the screw groove 104 and the countersunk screw hole 107. At this time, the strip plate 106 abuts and presses against the same end face of the metal filter screen 105, the lower metal filter screen 109 and the folded filter paper layer 110.
[0037] When it is necessary to replace the folded filter paper layer 110 or maintain the upper metal filter screen 105 and the lower metal filter screen 109, the operations (3), (2), and (1) can be performed in reverse.
[0038] Example 2
[0039] Based on the first embodiment, Figure 6The glass fiber high-temperature paint mist filter shown also includes an intermediate transition fiber filter layer 111;
[0040] The folded filter paper layer 110 has two layers, and the intermediate transition fiber filter layer 111 is located between the folded filter paper layers 110, with its two sides abutting against the opposite sides of the folded filter paper layers 110 respectively. The two side edges of the intermediate transition fiber filter layer 111 abut against the opposite sides of the strip plate 101 respectively. The intermediate transition fiber filter layer 111 is a glass fiber filter.
[0041] This structural design is optional and can be added according to the actual production and usage conditions, which can improve the efficiency of paint mist interception.
[0042] Example 3
[0043] Based on Example 1 or Example 2, such as Figure 5 The fiberglass high-temperature paint mist filter shown also includes a head flexible fixing washer 113 and a tail flexible fixing washer 112 respectively fitted on the upper metal filter screen 105 and the lower metal filter screen 109.
[0044] The outer walls of the first flexible fixing washer 113 and the last flexible fixing washer 112 are tightly fitted to the inner walls of the upper horizontal U-shaped groove 102 or the lower horizontal U-shaped groove 103, respectively.
[0045] After assembly, the flexible fixing washer 113 at the front end and the flexible fixing washer 112 at the rear end can respectively ensure the stability of the assembly between the upper metal filter screen 105, the lower metal filter screen 109 and the upper horizontal U-shaped groove 102 or the lower horizontal U-shaped groove 103.
[0046] Example 4
[0047] Based on Example 1, Example 2, or Example 3, such as Figure 5 The fiberglass high-temperature paint mist filter shown also includes a strip pressure plate fixing washer 114 fitted on the strip pressure plate 106;
[0048] The outer wall of the strip-shaped pressure plate fixing washer 114 is tightly fitted to the inner wall of one end face of the metal frame 100.
[0049] After this assembly is completed, the strip pressure plate fixing washer 114 can ensure the stability of the assembly between the strip pressure plate 106 and the inner wall of the metal frame 100.
[0050] This type of high-temperature glass fiber paint mist filter is suitable for use in filtration systems in painting workshops, ovens, etc.
