Disclosure of Invention

The utility model aims at solving current filter equipment, filtering is the snap-on setting on the frame, and the unable realization of filter house is dismantled and is changed, when changing, needs to change whole filter equipment, leads to the higher problem of replacement cost, provides a cotton filter equipment of compound static, can effectively solve above-mentioned problem.

The utility model aims at realizing through the following technical scheme: a composite electrostatic cotton filtering device comprises an outer frame, a filtering part and a pressing frame, wherein a limiting surface used for limiting one side of the filtering part is arranged on the outer frame, and the filtering part is arranged between the pressing frame and the limiting surface; the inboard of frame is provided with the buckle groove, is provided with on the inner wall in buckle groove to being used for carrying on spacing buckle to pressing the frame.

The utility model discloses in, the filter house is made by the cotton material of static, compresses tightly the filter house pressure through pressing the frame and fixes on the shell, carries out spacing fixed to pressing the frame through the spring bolt. When changing the filter house, only need with the buckle inwards push away make the buckle retract in the buckle groove, then take off and press the frame, take off the filter house that needs to be changed again, change new filter house, then adorn again back press the frame can. The utility model discloses in, the filter house can conveniently be dismantled and change, like this when filter equipment need change after using a period, only need to change the filter house can, need not to change whole filter equipment, reduced the replacement cost.

Preferably, the filter portion comprises a first electrostatic cotton filter layer and a second electrostatic cotton filter layer. The cotton filter layer of first static is arranged in the great solid particle of filtered air diameter, realizes first filtration, and the less solid particle of diameter realizes the secondary filtration in the second static filter layer is arranged in the filtered air, through the cooperation of the cotton filter layer of first static and the cotton filter layer of second static, can realize good filter effect.

Preferably, the filter unit is provided with mesh plates on both sides thereof, and the filter unit is sandwiched between the two mesh plates. The otter board is located the both sides of filter house, can play certain guard action to the filter house on the one hand, and two otter boards on the other hand are with the filter house clamp in the centre, can play the setting effect to the filter house.

Preferably, the mesh plate is made of stainless steel. The screen plate is made of stainless steel, so that the screen plate is not easy to rust and is convenient to maintain.

Preferably, the buckle and the outer frame are both made of plastic, and the buckle and the outer frame are integrally formed.

Preferably, one side of the pressing frame, which faces the filtering part, is provided with an annular positioning groove, a rubber ring is embedded in the annular positioning groove, and the rubber ring protrudes out of the surface of the pressing frame.

Preferably, the outer frame has a rectangular frame structure.

The utility model has the advantages that: the utility model discloses in, the filter house can conveniently be dismantled and change, like this when filter equipment need change after using a period, only need to change the filter house can, need not to change whole filter equipment, reduced the replacement cost.

Detailed Description

The invention will be further described with reference to the following detailed description and accompanying drawings.

Example 1:

as shown in fig. 1 to 8, a composite electrostatic cotton filter device includes an outer frame 1, a filter part, and a press frame 2. The outer frame 1 is a rectangular frame structure. The outer frame 1 is made of plastic. The outer frame 1 is provided with a limiting surface 7 for limiting one side of the filtering part. The filter part consists of a first static cotton filter layer 4 and a second static cotton filter layer 6. The cotton filter layer of first static 4 is arranged in the great solid particle of filtered air medium diameter, realizes first filtration, and the less solid particle of diameter realizes the secondary filtration in the second static filter layer 6 is arranged in the filtered air, through the cooperation of the cotton filter layer of first static and the cotton filter layer of second static, can realize good filter effect. The filtering part is rectangular and is matched with the outer frame 1. The filter part is arranged between the press frame 2 and the limiting surface 7. The two sides of the filtering part are respectively provided with a screen plate 3, and the filtering part is clamped between the two screen plates 3. The mesh plate 3 is made of stainless steel.
