When the rectangular frame is taken out of the shell, the end plate is disassembled, and the interior is cleaned and the filter membrane is replaced.

Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, and in particular to an air intake filter component. Background Technology

[0002] Equipment such as gas turbines that require air supply needs to filter the air when it is introduced. The air filters currently used use pre-filters to block and separate larger particles, and then filter the air through a filter membrane or cloth. However, the subsequent filter components have problems such as short service life and inconvenience in replacement. Utility Model Content

[0003] This utility model provides an air intake filter component to overcome the shortcomings of the prior art and solve the problem of inconvenient replacement or cleaning of after-effect filter membranes, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: An air intake filter component includes a housing with a rectangular cavity inside, a partition bar on the air intake side of the housing, and multiple filter sections inside the housing.

[0005] Furthermore, the outer shell includes a lower plate, with side plates formed by bending upwards at both ends of the lower plate, and a skirt formed by bending outwards at the upper end of the side plates, with a top cover fixed to the upper side of the skirt by screws.

[0006] Furthermore, the front end of the side plate is provided with multiple slanted slots, the inner end of the slanted slots extends upward at an angle, the inner end of the spacer is inserted into the slanted slots and fixed to the side plate by welding.

[0007] Furthermore, the filter section includes a fixing plate fixed to the lower plate by screws. The fixing plate is bent upward to form a concave part. The vertical section of the concave part is bent to form an L-shaped clip. A rectangular frame is inserted inside the clip. A rectangular window is opened on the rectangular frame. A V-shaped support is provided on the inner side of the rectangular frame. Multiple air holes are opened on the support. The opening of the support faces the rectangular window. A filter membrane is provided inside the support. V-shaped end plates are provided at the upper and lower ends of the support.

[0008] Furthermore, multiple vertical strips are welded to the upper wall of the plate at equal intervals, with the vertical strips located between two adjacent concave parts.

[0009] Furthermore, an outer sleeve is formed extending downward from the tip of the end plate. The outer sleeve is fitted over the tip of the support member and is fixed to the support member by fixing screws. An inner strip with a V-shaped structure is welded to the inner wall of the end plate, and the outer wall of the inner strip abuts against the filter membrane.

[0010] Furthermore, connecting plates are bent on both sides of the opening end of the support member. Multiple transverse and U-shaped slots are provided on the connecting plates. Multiple pairs of transverse and waist-shaped horizontal holes are provided on the rectangular frame. The horizontal holes and slots are in a one-to-one correspondence. A locking rod is inserted into the horizontal hole and its corresponding slot. One end of the locking rod on the same side is connected to an inner plate by a thread. The inner wall of the inner plate abuts against the outer wall of the connecting plate. The other end of the locking rod on the same side is connected to a front pull plate by a thread. An inner top screw is connected to the front pull plate by a thread. The inner end of the inner top screw abuts against the front side of the rectangular frame.

[0011] The advantages of the above technical solution are: This invention firstly uses downwardly inclined baffles to block larger particles in the air and discharge them outwards along the inclined surface, thereby reducing the filtration load on the filter section and extending the service life of the filter membrane.

[0012] Secondly, this invention improves filtration capacity by placing the filter membrane on the inner wall of a V-shaped support member. Firstly, this increases the filtration area, and secondly, the blocked, non-adhesive particles accumulate at the corners of the V-shaped support member as airflow occurs. These particles then impact the filter membrane as they pass through, causing some of the adhered fibers to fall off. Thirdly, it facilitates cleaning of the support member's interior and replacement of the filter membrane. For cleaning or replacement, the rectangular frame is removed from the outer casing, the end plate is disassembled, and the interior is cleaned and the filter membrane replaced.

[0021] The filter section 3 includes a fixing plate 30 fixed to the lower plate 10 by screws. The fixing plate 30 is bent upward to form a concave part 31. The vertical section of the concave part 31 is bent to form an L-shaped clip 32. A rectangular frame 33 is inserted inside the clip 32. A rectangular window is opened on the rectangular frame 33. A V-shaped support member 38 is provided on the inner side of the rectangular frame 33. A plurality of vent holes 40 are opened on the support member 38. The opening of the support member 38 faces the rectangular window. A filter membrane 45 is provided inside the support member 38.

[0022] The upper wall of the lower plate 10 is welded with multiple vertical strips 15 that are evenly spaced, and the vertical strips 15 are located between two adjacent concave parts 31.

[0023] An outer sleeve 42 extends downward from the tip of the end plate 41. The outer sleeve 42 is fitted over the tip of the support member 38 and is fixed to the support member 38 by a fixing screw 43. An inner strip 44 with a V-shaped structure is welded to the inner wall of the end plate 41, and the outer wall of the inner strip 44 abuts against the filter membrane 45.

[0026] In this embodiment, when cleaning or replacing the filter membrane 45, to avoid affecting the air supply, part of the filter membrane 45 is removed. After removal, the operator inserts a baffle plate into the clamp 32. Then, the operator performs operations such as replacing the filter membrane 45. During replacement, the operator first loosens the inner top screw, then moves the clamp 35 outward, then removes the support member 38, then unscrews the fixing screw 43, and removes the end plate 41. Then, the filter membrane 45 is taken out and re-fixed in the support member 38 by the inner strip 44. Then, the support member 38 is fixed to the rectangular frame 33 by the clamp 35.
