Description

Technical Field

[0001] This utility model relates to the field of air purification and filtration technology, and in particular to a high-efficiency filter with a U-shaped groove sealing frame. Background Technology

[0002] With the development of industry, such as semiconductors, LCD panels, and photovoltaic cells, the cleanliness requirements for the production environment are extremely high. For clean environments that need to operate continuously for a long time, such as hospital operating rooms and pharmaceutical workshops, reducing operation and maintenance costs and maintaining high air quality are also crucial.

[0003] Traditional equipment typically consists of a frame support assembly, a filter assembly, and a sealing assembly. The working principle is that during installation, the filter is fixed to the system's mounting frame, and the pre-tightening force of the bolts ensures that the sealing strip is in close contact with the mounting groove. After the dust-laden airflow enters the filtration system, the particulate matter in the air is filtered by the filter media.

[0004] However, in traditional equipment, the lack of a U-shaped groove frame and the reliance on mechanical compression sealing of the mounting frame solely by elastic sealing strips can easily lead to insufficient local compression, causing unfiltered air to directly penetrate the gaps, resulting in a significant decrease in filtration efficiency and failure to achieve a clean environment. In addition, the filter media and frame are mostly fixed connections, requiring the entire filter to be replaced during replacement. This process necessitates the complete removal of the frame fixings, which may compromise the sealing of the mounting frame and result in high maintenance costs.

[0005] Therefore, a high-efficiency filter with a U-shaped groove sealing frame is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a high-efficiency filter with a U-shaped groove sealing frame, which aims to improve the problems of insufficient sealing and the need to replace the entire filter material in the prior art due to the absence of a U-shaped groove frame.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A high-efficiency filter with a U-shaped groove sealing frame includes a first U-shaped frame, a second U-shaped frame on the right side of the first U-shaped frame, and U-shaped grooves inside both the first and second U-shaped frames. An installation assembly is disposed inside the first and second U-shaped frames, and an installation frame is disposed inside the first and second U-shaped frames. A slider is fixedly installed on the outer side of the installation frame. A filter assembly is disposed inside the installation frame. A fixing cylinder is fixedly connected inside the installation frame. A pull rod is slidably connected inside the fixing cylinder. A pressure strip is fixedly connected to the front side of the pull rod, and a spring is fixedly connected to the rear side of the pressure strip. The side of the spring away from the pressure strip is fixedly connected to the inner wall of the fixing cylinder.

[0008] Furthermore, the mounting component includes a limiting block, which is disposed inside the first U-shaped frame and the second U-shaped frame. Both the first U-shaped frame and the second U-shaped frame have limiting grooves inside. The limiting block is provided with a fixing bolt inside. The mounting frame is provided with a mounting groove inside.

[0009] Furthermore, the filter assembly includes a frame, inside which a glass fiber filter paper is fixedly installed, an activated carbon mesh is disposed on the right side of the glass fiber filter paper, and a protective mesh is disposed on the outside of the glass fiber filter paper and the activated carbon mesh.

[0010] Furthermore, the limiting block is slidably connected inside the limiting groove, and the fixing bolt is threaded through the insertion hole and connected inside the mounting groove.

[0011] Furthermore, the slider is slidably connected to the interior of the groove.

[0012] Furthermore, buffer pads are provided inside the first and second U-shaped frames, and the buffer pads are located inside the U-shaped grooves.

[0013] Furthermore, the lower side of the pressure strip is positioned to fit against the upper side of the slider.

[0014] Furthermore, the mounting frame is slidably connected inside the U-shaped groove, and the mounting frame is positioned directly above the buffer pad.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the two U-shaped grooves can be sealed together by the cooperation of the limiting groove, limiting block, fixing bolt, mounting groove and insertion hole, and the mounting frame can be fixed inside the U-shaped groove. At the same time, with the action of buffer pad and sealant, the problem of insufficient sealing effect, unfiltered air directly penetrating the gap and the filtration efficiency dropping significantly is solved. Thus, the mounting frame and filter material are sealed with the U-shaped groove, reducing wear during operation and increasing service life.

[0016] 2. In this utility model, the quick-fixing structure composed of a pull rod, a pressure bar, and a spring allows the mounting frame to be released simply by pulling and rotating the pull rod. Combined with the sliding design of the slider and the slide groove, the old filter component can be quickly removed and replaced. After replacement, the spring automatically drives the pressure bar to reset and fix it. No complicated tools are required, which greatly simplifies the maintenance process and improves the filter replacement efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model includes a U-shaped frame 1, a U-shaped frame 2 on the right side of the U-shaped frame 1, and U-shaped grooves 13 formed inside both the U-shaped frame 1 and the U-shaped frame 2. An installation component 3 is installed inside the U-shaped frame 1 and the U-shaped frame 2, and the installation component 3 includes a limiting block 31, which is disposed inside the U-shaped frame 1 and the U-shaped frame 2. Limiting grooves 32 are formed inside both the U-shaped frame 1 and the U-shaped frame 2. A fixing bolt 33 is installed inside the limiting block 31. The installation frame 5 is located inside... An installation groove 35 is provided, a limiting block 31 is slidably connected inside the limiting groove 32, a fixing bolt 33 is threaded through the insertion hole 34 and connected inside the installation groove 35, an installation frame 5 is provided inside the U-shaped frame 1 and U-shaped frame 2, a slider 7 is fixedly installed on the outside of the installation frame 5, the slider 7 is slidably connected inside the slide groove 8, a buffer pad 4 is provided inside the U-shaped frame 1 and U-shaped frame 2, the buffer pad 4 is located inside the U-shaped groove 13, the installation frame 5 is slidably connected inside the U-shaped groove 13, and the installation frame 5 is located directly above the buffer pad 4; Specifically, the limiting grooves 32 inside U-shaped frame 1 and U-shaped frame 2 are inserted into the limiting blocks 31. After U-shaped frame 1 and U-shaped frame 2 are sealed and connected by the limiting blocks 31, the buffer pad 4 is placed in the U-shaped groove 13. Then, the mounting frame 5 and the buffer pad 4 are fitted together in the U-shaped groove 13, so that the mounting groove 35 corresponds to the insertion hole 34. Then, the fixing bolt 33 is taken and passes through the limiting plate and also passes through the insertion holes 34 on the side of U-shaped frame 1 and U-shaped frame 2, and is threaded into the inside of the mounting groove 35. This solves the problem of insufficient sealing effect, unfiltered air directly penetrating the gap, and a significant decrease in filtration efficiency. Thus, the sealing effect of the mounting frame 5 and filter material with the U-shaped groove 13 is achieved. The buffer pad 4 reduces wear during operation and increases service life.

[0021] Reference Figure 2 , Figure 3 and Figure 5 In one embodiment of this utility model: a filter assembly 6 is provided inside the mounting frame 5. The filter assembly 6 includes a frame 61. A glass fiber filter paper 62 is fixedly installed inside the frame 61. An activated carbon mesh 63 is provided on the right side of the glass fiber filter paper 62. A protective mesh 64 is provided on the outside of the glass fiber filter paper 62 and the activated carbon mesh 63. A fixing cylinder 9 is fixedly connected inside the mounting frame 5. A pull rod 10 is slidably connected inside the fixing cylinder 9. A pressure strip 12 is fixedly connected to the front side of the pull rod 10. A spring 11 is fixedly connected to the rear side of the pressure strip 12. The side of the spring 11 away from the pressure strip 12 is fixedly connected to the inner wall of the fixing cylinder 9. The lower side of the pressure strip 12 is attached to the upper side of the slider 7. Specifically, when air passes through the filter, it first undergoes a first filtration through the glass fiber filter paper 62, and then a second filtration through the activated carbon mesh 63. The protective mesh 64 protects the glass fiber filter paper 62 and the activated carbon mesh 63 inside the filter. When replacing the filter, pull the lever 10. The lever 10 slides inside the fixed cylinder 9, which in turn drives the pressure strip 12 to slide. When the pressure strip 12 moves into the fixed cylinder 9, rotate the lever 10. The pressure strip 12 changes angle and is blocked inside the fixed cylinder 9. Remove the frame 61, and the slider 7 slides out in the groove 8, allowing the filter to be replaced. After replacement, rotate the pressure strip 12 to the position corresponding to the fixed cylinder 9, release the lever 10, and the pressure strip 12 is pushed out of the fixed slider 7 under the action of the spring 11, thus allowing the filter to be replaced and reducing maintenance costs.

[0022] Working principle: When using this device, first insert the limiting block 31 into the limiting groove 32 in the U-shaped frame 1 and the U-shaped frame 2, and seal the two U-shaped frames together. Then, place the buffer pad 4 into the U-shaped groove 13, and then place the mounting frame 5 and the filter assembly 6 on the buffer pad 4. Next, apply the sealing liquid to the U-shaped groove 13 to achieve a seal. Finally, insert the fixing bolt 33. The fixing bolt 33 fixes the U-shaped frame 1, the U-shaped frame 2, the limiting block 31 and the mounting frame 5 through the insertion hole 34 and the mounting groove 35. During operation, the air passes through the protective net 64 and is filtered by the glass fiber filter paper 62 and the activated carbon 63.

[0023] When the filter assembly 6 needs to be replaced, pull the lever 10. The lever 10 causes the pressure strip 12 to slide in the fixed cylinder 9. The pressure strip 12 compresses the spring 11. The outlet of the fixed cylinder 9 is semi-circular, corresponding to the shape of the spring pressure strip 12. Pull the spring pressure strip 12 into the fixed cylinder 9 and rotate it. At this time, after the spring pressure strip 12 is blocked inside the fixed cylinder 9, the slider 7 can slide out from the slide groove 8. Take out the frame 61, replace the new filter assembly 6, and adjust the angle of the pressure strip 12 until it can pop out of the fixed cylinder 9. The pressure strip 12 automatically returns to its original position and fixes the slider 7 under the action of the spring 11.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
