Description

Technical Field

[0001] This utility model relates to the field of medical clean operating rooms, specifically to an air purification filter box that is easy to inspect and replace. Background Technology

[0002] The fresh air system in a clean operating room includes a fan, a high-pressure air purification filter, and a laminar flow hood. The laminar flow hood is installed on the top of the operating room. The fresh air generated by the air conditioning fan is filtered by the air purification filter and then delivered to the operating room through the laminar flow hood.

[0003] Air purifier filters rely on the housing for installation and positioning. In the past, to ensure no air leakage, the installation structure of air purifier filters was directly locked with multiple bolts inside the housing. When replacing the filter inside the housing, it was necessary to disassemble the entire air inlet and outlet of the housing, resulting in low efficiency of filter disassembly, assembly and maintenance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an air purification filter box that is easy to inspect and replace, thus solving the technical problem that it is inconvenient to disassemble and inspect the air purification filter inside the box.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An air purification filter box that is easy to inspect and replace is provided, including...

[0007] The box body is a rectangular three-dimensional structure with an internal cavity inside. An air inlet is provided on the right side of the box body, and an air outlet is provided on the left side of the box body.

[0008] A filter is installed inside the housing, with its right side sealing against the inner end face of the air inlet.

[0009] The movable frame is inserted into the inner cavity of the box through the air outlet. The movable frame is connected to the box by multiple locking bolts. The inner end of the movable frame is sealed and abuts against the left side of the filter. The outer end of the movable frame is adapted to connect to the air outlet pipe. The air inlet of the box is adapted to connect to the air inlet pipe.

[0010] Door openings are provided on the front and rear sides of the housing, and the filter is adapted to be moved out through the two door openings. The door openings are equipped with openable and closable door panels.

[0011] Furthermore, a base is provided at the bottom of the inner cavity, and the lower end of the filter rests on the base.

[0012] Furthermore, a flange frame is provided inside the air inlet, and the flange frame is fixedly installed in the inner cavity, forming a sealed contact with the right side of the filter.

[0013] Furthermore, a first sealing strip is provided between the right end of the filter and the flange frame.

[0014] Furthermore, a second sealing strip is provided between the movable frame and the left end of the filter.

[0015] Furthermore, the filter is a pleated filter.

[0016] Furthermore, a differential pressure gauge is installed on the door panel, with its two probes extending to the air inlet and air outlet of the filter, respectively.

[0017] The beneficial effects of this utility model are:

[0018] The filter inside the chamber can be loosened by adjusting the tightness of the movable frame on the housing. Then, the filter can be removed from the door hole by opening the door panel. The installation and installation of the filter inside the housing is very convenient and the filter is relatively stable and reliable.

[0019] The differential pressure gauge installed on the door panel of the housing can monitor the pressure difference across the filter in real time, thereby determining in a timely manner whether the filter needs to be replaced.

[0020] By using a design that combines fixed and movable pressure frames, the need for a filter to be installed inside the housing and a mechanism to ensure airtightness between the front and rear chambers is eliminated. This also avoids the problem of leakage due to poor airtightness of the housing. The manufacturing process is simpler, and the airtightness is better. In addition, the airtightness can be checked quickly and intuitively by opening doors on both the left and right sides. Attached Figure Description

[0035] To address the technical problem of inconvenient disassembly and maintenance of the air purification filter 2 within the housing 1 in the prior art, one embodiment of this application provides an air purification filter housing that facilitates maintenance and replacement. This will be described in detail below.

[0036] like Figures 1 to 5 As shown, an air purification filter box that is easy to inspect and replace includes...

[0037] Box 1, which is a rectangular three-dimensional structure, has an inner cavity, an air inlet on the right side and an air outlet on the left side;

[0038] Filter 2 is installed in the inner cavity of housing 1, and the right side of filter 2 is sealed and abutted against the inner end face of air inlet;

[0039] The movable frame 3 is inserted into the inner cavity of the box 1 through the air outlet. The movable frame 3 is connected to the box 1 by multiple locking bolts 5. The inner end of the movable frame 3 is sealed and abutted against the left side of the filter 2. The outer end of the movable frame 3 is suitable for connecting the air outlet pipe. The air inlet of the box 1 is suitable for connecting the air inlet pipe.

[0040] Door openings are provided on the front and rear sides of the housing 1, and the filter 2 is adapted to be moved out from the front and rear door openings. The door openings are provided with openable and closable door panels 4.

[0041] Preferably in this embodiment, door panels 4 are provided on both the front and rear sides of the box body 1, and the door panels 4 are rotatably arranged through hinges in the door holes.

[0042] Specifically, as an alternative implementation manner in this embodiment, as Figure 3 and Figure 5 shown, a base 13 is provided at the bottom of the inner cavity, and the lower end of the filter 2 is placed on the base 13.

[0043] As Figure 3 shown, the base 137 has a "J" - shaped structure.

[0044] Specifically, as an alternative implementation manner in this embodiment, as Figure 5 shown, the upper end of the box body 1 is a top plate 11, and the lower end is a bottom plate 12. Both the top plate 11 and the bottom plate 12 are made of polyurethane foam boards.

[0045] As Figure 5 shown, the base 13 is placed on the bottom plate 12. By selecting a suitable base 13, the height of the filter 2 in the inner cavity can be controlled so that it can be aligned with the air inlet hole and the air outlet hole left and right.

[0046] Specifically, as an alternative implementation manner in this embodiment, as Figure 5 shown, a flange frame 14 is provided inside the air inlet hole. The flange frame 14 is fixedly arranged in the inner cavity, and the flange frame 14 forms a sealed abutment with the right side of the filter 2.

[0047] In this embodiment, the flange frame 14 is a rectangular frame structure and is fixed to the inner wall of the box body 1 by screws.

[0048] Specifically, as an alternative implementation manner in this embodiment, as Figure 3 shown, a first sealing strip 61 is provided between the right end of the filter 2 and the flange frame 14. A second sealing strip 62 is provided between the movable frame 3 and the left end of the filter 2.

[0049] Through the two sealing strips, the sealing performance between the filter 2 and the box body 1 is improved.

[0050] In this embodiment, the filter 2 is a pleated filter.

[0051] Specifically, as an alternative implementation manner in this embodiment, as Figure 1 shown, a differential pressure gauge 8 is provided on the door panel 4. The two detection heads of the differential pressure gauge 8 respectively extend to the air inlet end and the air outlet end of the filter 2. By detecting the differential pressure on both sides of the filter through the differential pressure gauge 8, the service life of the filter 2 can be judged.

[0052] In this embodiment, as Figure 3As shown, the movable frame 3 is a rectangular frame structure, and the locking bolt 5 between the movable frame 3 and the box 1 is a long bolt.

[0053] In this embodiment, as Figure 4 As shown, the movable frame 3 includes a pair of parallel inner connecting plates 31 and outer connecting plates 32. The outer connecting plate 32 is connected to the housing 1 by locking bolts 5. The inner connecting plate 31 abuts against the outlet of the filter 2, and a second sealing strip 62 is provided between the inner connecting plate 31 and the outlet of the filter 2.

[0054] In this embodiment, the flange of the air inlet pipe is sealed to the outside of the air inlet of the housing 1. The flange of the air outlet pipe is directly sealed to the movable frame 3.

[0055] The air purifier filter box maintenance process is as follows:

[0056] Determine whether filter 2 needs to be replaced by checking the differential pressure data on differential pressure gauge 8. If filter 2 needs to be replaced, loosen all locking bolts 5 on movable frame 3. At this time, it is not necessary to remove all locking bolts 5, just enough to allow movable frame 3 to loosen filter 2. Then open one side door panel 4 and pull filter 2 out of box 1 through the side door hole. Then install new filter 2 through the side door hole, tighten all locking bolts 5, clamp filter 2 between movable frame 3 and fixed frame, and finally close door panel 4.
