Description

Technical Field

[0001] This utility model relates to the field of chemical filter technology, and in particular to a multi-stage separation and purification honeycomb filter chemical filter. Background Technology

[0002] Chemical filters are devices specifically designed to remove harmful gases and odors from the air. Their core function is to purify polluted air through physical adsorption or chemical decomposition. They are widely used in industrial waste gas treatment, indoor air purification, laboratory ventilation systems, and other fields.

[0003] Current chemical filters typically have an inlet and an outlet. Harmful gases enter the equipment through the inlet and are purified by multiple layers of filter components such as activated carbon, zeolite, or PCO filter media. The filter materials remove harmful components from the gas through adsorption, catalytic oxidation, and other processes, and finally, clean air is discharged from the outlet.

[0004] Most existing chemical filters use a direct discharge method for their air inlets, which means that harmful gases are directly introduced into the equipment at high speed. Although this method is simple and direct, it will cause uneven distribution of gas on the surface of the filter element. This will cause some areas of the filter element to be overloaded due to concentrated airflow, while the areas not covered by airflow will be underutilized. After long-term operation, the areas covered by airflow will become saturated and fail, while the parts not covered by airflow will not be fully utilized, thereby reducing the overall filtration efficiency and the service life of the filter media. To address these issues, a multi-stage separation and purification honeycomb filter chemical filter is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-stage separation and purification honeycomb filter chemical filter, which aims to improve the problem mentioned in the prior art of "uneven airflow distribution in chemical filters, which reduces the filtration efficiency and service life of the filter components".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage separation and purification honeycomb filter chemical filter, including a filter box, an air outlet on one side of the filter box, an air inlet on the other side of the filter box, a filter assembly snapped into the inside of the filter box, and a turbulence mechanism and a cleaning mechanism provided inside the filter box and on the side near the air inlet. The flow-disrupting mechanism includes a guide plate hinged to the inner wall of the filter box, a flow equalization plate hinged to the outer wall of the guide plate, a slider slidably connected to the top of the guide plate, a motor fixedly connected to the top of the filter box, a rotating shaft fixedly connected to the output end of the motor, an L-shaped rod fixedly connected to the end of the rotating shaft away from the motor, and a protruding rod fixedly connected to the side of the flow equalization plate near the guide plate, with a connecting rod hinged to the end of the protruding rod away from the guide plate.

[0007] As a further description of the above technical solution: The cleaning mechanism includes a rotating rod, which is rotatably connected to the inner wall of the filter box, and the rotating rod is connected to the rotating shaft by a transmission belt.

[0008] As a further description of the above technical solution: A spring is fixedly connected to the outer wall of the rotating rod, and a steel ball is fixedly connected to the end of the spring away from the rotating rod.

[0009] As a further description of the above technical solution: The filter assembly includes a filter frame that is snapped onto the inner wall of the filter box.

[0010] As a further description of the above technical solution: The inner wall of the filter frame is sequentially connected from left to right to an activated carbon layer, PCO filter media, molecular sieve, and honeycomb filter.

[0011] As a further description of the above technical solution: A sealing ring is fixedly connected to the outer wall of the filter frame.

[0012] As a further description of the above technical solution: The end of the L-rod away from the pivot is rotatably connected to the inner wall of the slider.

[0013] As a further description of the above technical solution: The end of the connecting rod away from the convex rod is hinged to the side wall of the slider.

[0018] 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.

[0019] Reference Figures 1-3 The present invention provides an embodiment of a multi-stage separation and purification honeycomb filter chemical filter, comprising a filter box 1, an air outlet 2 on one side of the filter box 1, an air inlet 3 on the other side of the filter box 1, and a filter assembly 4 snapped into the inside of the filter box 1. In use, exhaust gas enters the interior of the filter box 1 through the air inlet 3, and the filter assembly 4 is used to filter the exhaust gas. The filtered exhaust gas is discharged from the filter box 1 through the air outlet 2. A turbulence mechanism 5 and a cleaning mechanism 6 are provided inside the filter box 1 and on the side near the air inlet 3.

[0020] Reference Figure 2 , Figure 4 and Figure 5The turbulence mechanism 5 includes a guide plate 51, which is hinged to the inner wall of the filter box 1. The reciprocating swing of the guide plate 51 can guide the exhaust gas discharged into the filter box 1 through the air inlet 3, causing the exhaust gas to diffuse to the left and right sides of the air inlet 3. A flow equalization plate 52 is hinged to the outer wall of the guide plate 51. The reciprocating swing of the guide plate 51 can guide the exhaust gas discharged into the filter box 1 through the air inlet 3, causing the exhaust gas to diffuse to the upper and lower sides of the air inlet 3. A slider 53 is slidably connected to the top of the guide plate 51. When the L rod 56 pushes and pulls the slider 53 back and forth, the slider 53 will push and pull the guide plate 51 back and forth, causing the guide plate 51 to swing back and forth on the inner wall of the filter box 1.

[0021] Reference Figure 1 and Figure 5 A motor 54 is fixedly connected to the top of the filter box 1. A rotating shaft 55 is fixedly connected to the output end of the motor 54. The end of the rotating shaft 55 away from the motor 54 passes through the filter box 1 and is fixedly connected to an L-shaped rod 56. The rotating shaft 55 is rotatably connected to the filter box 1 at the point where it passes through. When the motor 54 is started, it drives the rotating shaft 55 to rotate. As the rotating shaft 55 rotates, it drives the L-shaped rod 56 at its bottom end to move in a circular motion around the rotating shaft 55. The end of the L-shaped rod 56 away from the rotating shaft 55 is rotatably connected to the inner wall of the slider 53. The L-shaped rod 56 moves in a circular motion around the rotating shaft 55. During the cycle, L-bar 56 pushes and pulls slider 53 back and forth, causing slider 53 to slide back and forth on the top of guide plate 51. A protruding rod 57 is fixedly connected to the side of flow equalizer 52 near guide plate 51. A connecting rod 58 is hinged to the end of protruding rod 57 away from guide plate 51. The end of connecting rod 58 away from protruding rod 57 is hinged to the side wall of slider 53. While slider 53 slides back and forth on the top of guide plate 51, it can work with connecting rod 58 and protruding rod 57 to drive flow equalizer 52 to swing up and down on the outer wall of guide plate 51.

[0022] Reference Figure 2 The cleaning mechanism 6 includes a rotating rod 61, which is rotatably connected to the inner wall of the filter box 1. The rotating rod 61 is connected to the rotating shaft 55 by a transmission belt 64. When the rotating shaft 55 rotates, it can drive the rotating rod 61 to rotate synchronously with the transmission belt 64. A spring 62 is fixedly connected to the outer wall of the rotating rod 61. When the rotating rod 61 rotates, it can drive the steel ball 63 to make a circular motion around the rotating rod 61 with the spring 62. The end of the spring 62 away from the rotating rod 61 is fixedly connected to the steel ball 63. The steel ball 63 can knock off the particles attached to the surface of the honeycomb filter screen 45 by striking it.

[0023] Reference Figures 2-4The filter assembly 4 includes a filter frame 41, which is snapped onto the inner wall of the filter box 1. The filter frame 41 is fixed to the inner wall of the filter box 1 with bolts. After removing the bolts, the filter frame 41 can be removed from the inside of the filter box 1 to replace the filter material inside. The inner wall of the filter frame 41 is sequentially connected from left to right with an activated carbon layer 42, PCO filter media 43, molecular sieve 44, and honeycomb filter 45. The activated carbon layer 42 uses its porous structure to adsorb irritating odors in the exhaust gas. The PCO filter media 43 uses a catalyst to oxidize and decompose pollutants into harmless substances. The microporous structure of the molecular sieve 44 filters fine particles in the exhaust gas. The honeycomb filter 45 performs preliminary filtration of solid particles in the exhaust gas. A sealing ring 46 is fixedly connected to the outer wall of the filter frame 41 to seal the connection between the filter frame 41 and the filter box 1.

[0024] Working principle: During use, exhaust gas enters the interior of filter box 1 through air inlet 3. At this time, honeycomb filter 45 performs preliminary filtration of solid particles in the exhaust gas. Then, molecular sieve 44 is used to filter fine particles in the exhaust gas. When the filtered exhaust gas passes through PCO filter material 43, harmful gases in the exhaust gas are decomposed by PCO filter material 43. Finally, the irritating odor in the exhaust gas is filtered through activated carbon layer 42. After multiple filtrations, the exhaust gas is finally discharged from filter box 1 through air outlet 2.

[0025] While filtering the exhaust gas, the motor 54 is started, driving the rotating shaft 55 to rotate. As the rotating shaft 55 rotates, it drives the L-shaped rod 56 at its bottom to rotate in a circular motion around the shaft. Simultaneously, the L-shaped rod 56 pushes and pulls the slider 53 back and forth, causing the slider 53 to slide back and forth on the top of the guide plate 51. The slider 53 also pushes and pulls the guide plate 51 back and forth, causing the guide plate 51 to oscillate against the inner wall of the filter box 1. This oscillation of the guide plate 51 guides the exhaust gas entering the filter box 1 through the air inlet 3, causing the exhaust gas to diffuse to the left and right sides of the air inlet 3. This allows the exhaust gas to be evenly distributed on the surface of the filter assembly 4. At the same time, the slider 53 slides back and forth on the top of the guide plate 51 and pushes and pulls the connecting rod 58 back and forth, causing the connecting rod 58 to push and pull the protruding rod 57 back and forth. At this time, the protruding rod 57 will drive the flow equalizing plate 52 to swing up and down on the outer wall of the guide plate 51. The up and down swing of the guide plate 51 can guide the exhaust gas discharged into the filter box 1 from the air inlet 3, so that the exhaust gas can diffuse to the upper and lower sides of the air inlet 3. The back and forth swing of the guide plate 51 and the flow equalizing plate 52 can make the exhaust gas evenly diffuse on the surface of the filter component 4, thereby making full use of the filtration effect of the filter component 4.

[0026] While the rotating shaft 55 is rotating, it can drive the rotating rod 61 to rotate synchronously in conjunction with the transmission belt 64. While the rotating rod 61 is rotating, it can drive the steel ball 63 to make a circular motion around the rotating rod 61 in conjunction with the spring 62. At the same time, the steel ball 63 will periodically tap the surface of the honeycomb filter screen 45 to shake off the particles attached to the surface of the honeycomb filter screen 45, so as to avoid the accumulation of impurities that will cause the honeycomb filter screen 45 to become clogged and thus affect the filtration effect of the filter assembly 4.

[0027] 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.
