Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, and in particular to a high-efficiency filter. Background Technology

[0002] High-efficiency particulate air (HEPA) filters are air filtration devices used to capture particulate dust and various suspended matter larger than 0.5μm in the air. During use, they adsorb and isolate particulate dust through relevant filtration devices, thus achieving the filtration of the gas to be used. They play a vital role in the air purification industry.

[0003] For example, in the prior art, there is a high-efficiency filter, patent number: CN114768391B, which filters dust-laden gas by introducing the dust-laden gas into the housing from the air inlet end. The dust-laden gas flows through the filter bag, and the particulate matter in the dust-laden gas is intercepted by the filter bag and accumulates on the side of the filter bag facing the air inlet end of the housing. The clean gas formed after the dust-laden gas is filtered is discharged from the air outlet end of the housing.

[0004] However, in existing technologies, the minimum pore size of the filter bag and the filtration level of the device are fixed, making it impossible to filter the gas to a specified purification level according to the required purification requirements. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency filter to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency filter, comprising a filter housing for installing a filter device, wherein the filter housing is provided with three guide grooves arranged in a 90-degree circumferential array, and a guide rod is fixedly connected inside each guide groove; a filter plate is slidably connected inside the filter housing and on the guide rod; and a return spring is sleeved between the end of the guide rod and the filter plate.

[0007] Preferably, the filter housing has mounting grooves at both the top and bottom where it connects to the outside, and each mounting groove is provided with a conical spout, with the conical openings of the two conical spouts facing outwards.

[0008] Preferably, the filter housing has mounting grooves at both the top and bottom where it connects to the outside, and each mounting groove is provided with a conical spout, with the conical openings of the two conical spouts facing outwards.

[0009] Preferably, a slot is provided on the end face of the filter housing away from the limiting ring, and a sealing block is inserted into the slot, and the sealing block completely covers the limiting rod and the connection between the outer surface and the interior of the filter housing.

[0010] Preferably, a handle is also fixedly connected to the outer surface of the filter housing.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up a filter housing, guide groove, guide rod, filter plate and reset spring, and in combination with the filtration requirements of the gas to be filtered, a filter plate is added to the guide rod inside the filter housing to improve the filtration accuracy. At the same time, combined with the resistance of the reset spring, the gas to be filtered is introduced into the device and passes through each filter plate in sequence to complete the filtration.

[0013] 2. In this utility model, by setting conical spouts at both ends of the device, with the conical openings of both spouts facing outwards, the gas enters the device and passes through the conical openings to the filter plate inside the device, increasing the contact area between the gas and the filter plate. At the same time, after filtration, the gas passes through the conical spouts at the ends, reducing the outlet area, increasing the gas flow rate, and accelerating the collection of the filtered gas.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] like Figure 1-3As shown, a high-efficiency filter includes a filter housing 1 for installing a filter device. The filter housing 1 has three guide grooves 3 arranged in a 90-degree circular array inside. Each guide groove 3 is fixedly connected to a guide rod 4. A filter plate 5 is slidably connected inside the filter housing 1 and on the guide rod 4. A return spring 6 is sleeved between the end of the guide rod 4 and the filter plate 5.

[0021] The filter housing 1 has mounting grooves 7 at both the top and bottom where it connects to the outside. Each mounting groove 7 has a conical spout 8, and the conical openings of both spouts 8 face outward.

[0022] Further explanation of this solution: Before starting the filtration process, open the filter housing 1, and with the resistance of the return spring 6 on the guide rod 4, insert an appropriate number of filter plates 5 into the filter housing 1 and onto the guide rod 4 according to the specified filtration requirements.

[0023] After the above work is completed, the gas to be filtered is introduced into the filter housing 1 through one of the conical spouts 8 inside the filter housing 1. The gas to be filtered passes through the filter plate 5 inside the device in sequence and is filtered. At the same time, the conical spout 8 at the end of one filter and the conical spout 8 at the beginning of another filter can be connected by a plastic water pipe to increase the filtration process and further improve the filtration effect.

[0024] like Figure 1 and Figure 2 As shown, the outer surface of the filter housing 1 has three grooves 9 arranged in a circular array. The outer surface of the filter housing 1 is also fitted with a limiting ring 10, and a limiting strip 11 that is completely engaged with the groove 9 is fixedly connected inside the limiting ring 10. A mounting block 15 is fixedly connected to the limiting ring 10, and a limiting rod 12 is fixedly connected to the mounting block 15. The part of the filter plate 5 that passes through the filter housing 1 and extends outward is fitted onto the limiting rod 12.

[0025] Further explanation of this solution: The limiting ring 10 fitted on the outer surface of the filter housing 1 restricts the opening of the filter housing 1, while the limiting rod 12 fixedly connected to the mounting block 15 restricts the filter plate 5. Under the premise of low gas flow rate, the filter plate 5 can be moved along the limiting rod 12 by moving the outwardly protruding part of the filter plate 5, thereby adjusting the unit filtration volume and further improving the filtration effect.

[0026] like Figure 3 As shown: A slot 13 is provided on the end face of the filter housing 1 away from the limiting ring 10. A sealing block 14 is inserted into the slot 13, and the sealing block 14 completely covers the limiting rod 12 and the connection between the outer surface and the interior of the filter housing 1.

[0027] The purpose of this solution is to ensure the airtightness of the device by inserting a sealing block 14 into the slot 13, so that the sealing block 14 covers the gap between the filter housing 1 and the outside, thus preventing air leakage from affecting the filtration effect.

[0028] like Figure 1 As shown, a handle 2 is also fixedly connected to the outer surface of the filter housing 1.

[0029] Further explanation of this solution: The handle 15 improves the portability of the device, making it easier to grip and move the filter.

[0030] Working principle: The gas to be filtered is introduced into the filter housing 1 through the conical spout 8. Combined with the diffusion effect of the conical spout 8, the gas to be filtered passes through the filter plate 5 set in advance inside the device and comes into full contact with it, thereby achieving filtration of the gas to be filtered.

[0031] Meanwhile, the purpose of the reset spring 6 in this scheme is that when the input airflow velocity is relatively fast, as the number of filter plates 5 increases, the reset spring 6 can hold the filter plates 5 inserted into the device to prevent the filter plates 5 from shifting on the guide rod 4. Therefore, when the airflow velocity is relatively low, the reset spring 6 can be ignored.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
