Problems solved by technology

The filter screen in the prior art includes stainless steel wire mesh gas-liquid separation and degreasing net and stainless steel belt or aluminum strip curved wavy degreasing net; the stainless steel wire mesh gas-liquid separation degreasing net is formed by stacking after flattening tubular stainless steel wire mesh , there is no air flow channel between the mesh, the advantages are: good degreasing effect and simple manufacture; the disadvantages are: 1. Large wind resistance; 2. Large amount of materials; 3. Difficult to clean
The stainless steel strip or aluminum strip curved wave degreasing net is made of stainless steel strips (or aluminum strips) that are pressed into curved waves and then stacked. The entire filter element is corrugated, and airflow channels are designed between the mesh pieces. The advantages are: 1. Easy to clean ; 2. Good degreasing effect; 3. Small wind resistance; Disadvantages are: 1. Because the mesh is pressed by stainless steel strip or aluminum strip, the weight is the highest among the three; 2. The manufacturing process is the most difficult among the three
[0003] In addition, the filter screen in the prior art is made by glue-coating and stacking process. Glue is applied between the mesh sheets, fixed with a specific fixture, and then baked in an oven to make them stick to each other. There are the following disadvantages: 1. .The bonding strength of the glue is not high, so the overall strength of the filter element is not high, and it is easy to disperse during transportation and framing; 2. The oven bakes for a long time, which affects production efficiency; 3. The oven consumes high energy and is greatly affected by the climate , the lower the temperature, the higher the humidity, the higher the energy consumption

Embodiment 1

[0046] refer to Figure 1-3 , the present embodiment provides a filter screen 10, comprising laminated multilayer corrugated mesh sheets 11, each layer of the corrugated mesh sheet 11 is pressed from a wire mesh with mesh, and each layer of the corrugated mesh sheet 11 includes A plurality of curved grooves 111, each layer of the corrugated mesh sheet 11 includes a plurality of crests and a plurality of troughs, the crests and troughs between each adjacent two layers of the corrugated mesh are arranged oppositely, each Two adjacent layers of the corrugated mesh sheets are fixedly connected by welding, so that a plurality of curved filter channels 12 are enclosed between each adjacent two layers of the corrugated mesh sheets.

[0047]The shape of the curved groove of the corrugated mesh sheet is cosine linear, and the wire mesh is stainless steel mesh, so that its thickness is much higher than that of the stainless steel mesh for gas-liquid separation and oil removal. , The nu...

Embodiment 2

[0051] refer to Figure 1-4 , a filter device, comprising a frame 20, the frame 20 is provided with an accommodation cavity, the front of the frame 20 is provided with an air inlet communicating with the accommodation cavity; the back of the frame is provided with a The air outlet connected to the housing cavity; also includes the filter screen 10 described in embodiment 1, the filter screen 10 is arranged in the housing chamber; the inlet of each filter channel of the filter screen 10 is all towards the air inlet, filtering The outlet of each filter channel of the net faces the air outlet.

[0052] The air inlet is provided with a metal grid 30, and the air outlet is provided with a metal grid 30, so that the overall strength of the mesh surface is greatly improved, and the obstruction to the airflow is minimal. The metal grid 30 is a stainless steel grid.

[0053] Four oil dripping holes 23 are respectively provided at the four corners of the frame body 20 .

Abstract

The invention discloses a filter screen. The filter screen comprises a plurality of laminated corrugated mesh sheets, each corrugated mesh sheet is formed by pressing a metal wire mesh sheet with meshes and comprises a plurality of curve-shaped grooves and further comprises a plurality of wave crest parts and a plurality of wave trough parts, the wave crest parts and the wave trough parts betweenevery two adjacent corrugated mesh sheets are oppositely arranged, and every two adjacent corrugated mesh sheets are fixedly connected in a welded mode, so that a plurality of curve-shaped filter channels are defined between every two adjacent corrugated mesh sheets. The invention further discloses a filter device comprising the filter screen and a manufacturing method for the filter device. The filter screen has the advantages of being small in ventilation resistance, good in oil removal effect, high in connection strength and convenient to clean; the whole filter screen is connected into a firm whole through a welding process, and therefore the strength is greatly improved, and the filter screen is easy to install and transport; and in addition, continuous production can be realized, theproduction efficiency is high, and the influence caused by the climate can be avoided.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter net, a filter device and a manufacturing method thereof. Background technique [0002] The oil fume filter device is mainly used to purify the oil fume discharged from the kitchen and prevent the oil fume from polluting the environment. The filter screen in the prior art includes stainless steel wire mesh gas-liquid separation and degreasing net and stainless steel belt or aluminum strip curved wavy degreasing net; the stainless steel wire mesh gas-liquid separation degreasing net is formed by stacking after flattening tubular stainless steel wire mesh , No air flow channel is designed between the mesh, the advantages are: good degreasing effect and simple manufacture; the disadvantages are: 1. Large wind resistance; 2. A lot of materials used; 3. It is not easy to clean. The stainless steel strip or aluminum strip curved wave degreasing net is made of stainless steel strips (or alumi...
