Abstract

The invention discloses filter units which comprise a screen body and a covering edge, wherein the screen body comprises an air inlet surface and an air outlet surface; the air inlet surface and the air outlet surface are oppositely arranged; the covering edge surrounds the periphery of the screen body; one side edge of the covering edge protrudes from the air inlet surface; the other side edge of the covering edge protrudes from the air outlet surface; a first mounting part and a second mounting part are respectively arranged on at least two opposite outer sides of the screen body on the covering edge; the first mounting part of one screen body is used for being fixedly connected with the second mounting part of another screen body in a detachable manner. The invention further discloses a filter screen adopting the filter units. The filter units and the filter screen not only are high in strength and resistant to screen body abrasion, but also can be assembled and disassembled conveniently and rapidly, so that the maintenance cost is reduced.

Description

technical field

[0001] The invention relates to a filter device, in particular to a filter unit and a filter net. Background technique

[0002] In the air filtration device, a filter is often configured to filter the impurity particles in the air. Ordinary filter screen is a network body composed of multiple interwoven wires. The filter screen is installed between the air inlet and air outlet of the filter, and the air will pass through the mesh of the network body. Due to the limited filtration and adsorption life of the filter screen, it is often necessary to replace the filter screen.

[0003] However, in current filters with replaceable filter screens, the filter screen is generally inserted into the slot of the filter, and friction or relative extrusion will occur between the filter screen and the slot, and the screen body will be easily damaged during assembly and disassembly. , affecting the filtering effect. Moreover, when the filter is shaken, the mesh body is al...

Embodiment Construction

[0027] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0028] Such as Figure 1~2 The shown protective filter unit includes a mesh body 1 and a wrapping 2. The mesh body 1 has a relative wind inlet surface 11 and an air outlet surface 12. The wrapping edge 2 is arranged around the periphery of the mesh body 1, and the wrapping edge One side edge of 2 protrudes from the wind inlet surface 11, and the other side edge of the wrapping 2 protrudes from the wind outlet surface 12; at least two opposite wrapping 2 outer sides of the mesh body 1 are respectively provided with first installation parts 101 And the second installation part 102, the first installation part 101 is used to be fixedly connected with the second installation part 102 of another mesh body 1 in a detachable manner.

[0029] The material of the mesh body 1 in this example can be PP cotton, ceramics, aluminum honeycomb, etc. In order to realiz...
