[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] like Figure 1-Figure 6As shown, a filtering processing unit for an air filter comprises a shell; an air inlet is provided at one end of the shell, and an air flow cavity with one end connected to the air inlet and the other end closed is formed in the shell; an air outlet is provided on at least one side wall of the shell; a filter assembly is provided on the air outlet, and the filter assembly comprises a plurality of fins arranged in sequence and spaced apart along the gas flow direction in the air flow cavity, and air flow channels are formed between adjacent fins respectively; the cross-section of the air flow channel is streamlined, so that the air flow can make a second turn in the process of flowing from its inlet to its outlet in the air flow channel; the air flow channel is configured so that the flow area at at least one position inside it is larger than the flow area at its inlet, so that the dust in the air flow is slowly settled by reducing the air flow velocity, and then is collected by the filter plate 106. A positive baffle 101, wherein both sides of the positive baffle 101 are fixedly connected to side baffles 102, and both sides of the side baffles 102 are fixedly connected to air inlet arc plates 104, and the filter 106 is fixedly connected to the side baffles 102. A square closed loop formed by the two air inlet arc plates 104 and the two side baffles 102 constitutes an air inlet. A square closed loop formed by the air inlet arc plates 104, the two side baffles 102 and the positive baffle 101 constitutes an air outlet. The two air outlets are symmetrically distributed on both sides of the positive baffle 101. The filter assembly includes a plurality of support rods 107, one end of the support rod 107 is fixedly connected to the positive baffle 101, and the other end is fixedly connected to the air inlet arc plate 104 on the same side, and a plurality of filter plates 106 are fixedly connected to the support rods 107.

[0028] When the air pressure difference between the air inlet and the air outlet is basically the same, the difference range is ±500pa; at this time, the air flow enters from the air inlet, and the air inlet of the air flow channel faces away from the air inlet. At this time, the air flow flows back to the gap between the filter plates 106. Due to the resistance, energy loss occurs and the air flow begins to decelerate for the first time. Since the sum of the minimum gap areas between the filter plates 106 is greater than the air inlet area, that is, the sum of the lengths of all A is greater than the length of C, the air flow begins to decelerate for the second time when it enters the gap between the filter plates 106, and at this time the air flow makes a second turn, and then the air flow is The airflow flows from the small gap, i.e., A, to the maximum gap, i.e., B, at which point the airflow slows down again, and then turns for the third time, from the maximum gap to the minimum gap, at which point the airflow begins to accelerate; since the gap between the filter sheets 106 changes from small to large and then to small, when the airflow turns at the maximum gap, since the airflow velocity is very slow, most of the impurities and dust carried in the airflow will stay in the depression of the filter sheet 106 farthest from the opening, thereby achieving a filtering effect; then the airflow will flow out of the minimum gap between the filter sheets 106, and then flow out through the air outlet.

[0029] When the air pressure difference between the air inlet and the air outlet is large, the difference here is greater than 10Kpa; at this time, the air flow velocity increases sharply when entering from the air inlet, and even after multiple decelerations, the air flow velocity is still large. Therefore, at this time, the dust and impurities collected in the depression of the filter 106 will be taken away by the air flow, and then discharged through the air outlet to complete the cleaning operation.

[0030] Through the above arrangement, the problem that the filter unit needs to be removed and replaced after long-term use is solved, and the long-term use of the filter unit can reduce costs and reduce labor intensity without the need for removal and replacement; at the same time, by repeatedly slowing down the airflow, the dust in the air can be better settled and then collected, achieving a technical effect of good purification effect and simple structure.

[0031] Embodiment 2:

[0032] like Figure 4 As shown, the filter sheet 106 is composed of an arc sheet and flat sheets symmetrically distributed on both sides of the arc sheet and fixedly connected thereto, wherein the flat sheet is tangent to the arc sheet, and the angle between the two flat sheets is 30°-50°, preferably 38°. Through the above arrangement, when cleaning dust, the dust collected on the filter sheet 106 can be discharged smoothly and will not remain on the arc sheet, thereby ensuring the cleaning effect.

[0033] like Figure 3 , Figure 5 , Figure 6 As shown, the end of the air inlet arc plate 104 away from the air inlet is fixedly connected to the connecting plate 108, and a plurality of threaded holes are provided on the connecting plate 108. Through the above arrangement, two adjacent connecting plates 108 in the present application can be locked together by bolts, so that the present application can be stacked and used in combination, and the specific number is determined according to actual needs, and the combination is convenient and quick.

[0034] like Figure 3 As shown, the side baffle 102 is fixedly connected to the mounting plate 105, which is a quarter circle, with one plane of the mounting plate 105 in contact with the side baffle 102 and the other plane flush with the connecting plate 108. The mounting plate 105 is provided with a plurality of threaded holes, which are opened axially along the mounting plate 105. Through the above arrangement, the present application can be quickly installed in the housing using bolts and can be put into use.

[0035] like Figure 2 As shown, the height of the air inlet is greater than the height of the positive baffle 101. Through the above arrangement, the volume of the positive baffle 101 can be effectively reduced, the overall mass can be reduced, and the investment cost can be reduced.

[0036] like Figure 1As shown, a plurality of reinforcing ribs 103 are symmetrically arranged on both sides of the positive baffle 101, and the reinforcing ribs 103 are fixedly connected to a plurality of filter sheets 106 on the same side. Through the above arrangement, the filter sheets 106 can be installed more stably, and the filter sheets 106 can be prevented from shaking, thereby ensuring the stability of the device operation.

[0037] Working principle: When filtering, ensure that the pressure difference between the air inlet and the air outlet is basically the same. At this time, the air flow enters from the air inlet and passes through the gap between the filter plates 106, that is, the air flow channel. Dust and impurities will stay at the arc plate, that is, the largest spacing, and then the clean air flow will be discharged through the air outlet for use. After this application has been working for a period of time, the air pressure at the air outlet will be reduced. At this time, due to the large pressure difference at both ends, the air flow rate increases sharply, so the dust collected on the filter plate 106 will be discharged, thereby achieving the purpose of cleaning.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
