Problems solved by technology

However, since the paint or plastic on this metal shell is sprayed, its anti-corrosion and anti-static performance is not good, and it is easy to fall off and oxidize, so that moisture or dust particles in the air will easily adhere to the metal shell. On the casing, the casing is corroded and oxides are produced, which shortens the service life of the high-efficiency filter and cannot meet the environmental requirements. The static electricity and oxide dust particles generated by it seriously affect the working environment, resulting in serious In addition, oxide d...

Abstract

The invention discloses a high-efficiency filter which comprises a shell, a steel frame and a filter element, wherein, the top of the shell is provided with an air inlet, and a fixedly connected U-shaped space is formed between the steel frame and the outer wall of the filter element. The high-efficiency filter is characterized in that the shell is made of plastic and has a reverse U shape; and the lower end of the shell is inserted into the U-shaped space formed between the steel frame and the outer wall of the filter element. As the shell of the high-efficiency filter adopts the plastic as the raw material and can be formed by injection molding in one step, the shell has very high sealing waterproof property, anticorrosive property and antistatic performance, thus effectively solving the problems of easy shedding of the paint or plastic coating on the surface of metal shell and air deterioration caused by dust particle generation as well as effectively reducing the cost and playing a positive role in saving energy and protecting environment.

Example Embodiment

[0021] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0022] figure 1 Is a front view of an embodiment of the present invention; figure 2 for figure 1 An enlarged view of Part A; image 3 Is a top view of an embodiment of the present invention; Figure 4 It is a bottom view of an embodiment of the present invention.

[0023] Such as Figure 1 to Figure 4 As shown, the high-efficiency filter includes a housing 2, a filter element 1 and a steel frame 4. The top of the housing is provided with an air inlet 8. The steel frame 4 and the outer wall of the filter element 1 form a U-shaped space that is fixedly connected. The material of the housing 2 It is plastic with a shape of ∩, which can be injection molded at one time by a mold, and the lower end of the housing 2 is inserted into the U-shaped space formed by the steel frame 4 and the outer wall of the filter element 1.

[0024] In addition, an FFU fan 3 can be installed at the air inlet 8 to form a high-efficiency filter containing FFU to meet the special requirements of special environments.

[0025] The inner wall of the lower end of the housing 2 is provided with a clamping tooth 5, and the outer wall surface of the filter element 1 is provided with a clamping groove 6 that matches with the said clamping tooth. A clamping groove 6 can also be provided on the inner wall of the lower end of the housing 2. , And the outer wall surface of the filter element 1 is provided with a clamping tooth 5 that is matched with the groove, which can enhance the sealing between the housing 2 and the filter element 1. In addition, a reset hole and one end are fixed on the inner wall of the lower end of the housing 2 The spring in the reset hole to install and replace the high efficiency filter element 1.

[0026] A sealing groove 7 is also provided on the inner wall surface of the bent portion of the housing 2, and the sealing groove 7 is a right-angled shape, which can further enhance the sealing performance of the housing 2.

[0027] The color of the shell can be changed arbitrarily according to the needs of users.

[0028] The air with dust particles enters from the air inlet 8 through the FFU fan 3, and after being filtered by the filter element 1, the particles in the air are filtered and left behind, and the purified air enters the machine through the filter element 1.
