Abstract
The utility model discloses a filter unit of a spraying type etching machine. The filter unit comprises a filter unit body which is arranged at a return pipe port in an etching cabin and covers the total return pipe port, the filter unit body comprises a support, and a coarse filter screen and a fine filter screen are sequentially arranged on the support from top to bottom. The filter screens are added in the etching cabin of the etching machine to perform two-stage filtration, the coarse filter screen is mainly used for filtering large impurity particles in first-stage filtration, the fine filter screen is used for filtering small impurity particles in second-stage filtration, parts of impurities (mainly including silicate and other impurities) in etched acid liquor are filtered, the impurities which are filtered out are cleaned manually at regular intervals, and the filter unit is simple in principle and convenient to operate.
Description
Technical field
The utility model relates to a kind of device that crystal in the later mixed chemical article of electronics nitration mixture (hydrofluoric acid, sulfuric acid, nitric acid) and TFT-LCD glass reaction and other impurity are filtered, and relates in particular to a kind of fountain etching machine filter.
Background technology
At present; The mode that generally adopt in TFT-LCD attenuate field is fountain and immersion type; Need recycle acid solution to the fountain reduction process, contain a large amount of silicate (thick, crystalloid) and other solid impurities in the recovered acid, must filter it; The control cleanliness factor, otherwise can cause shower nozzle to stop up and the bad order of glass after etching.
Summary of the invention
Problem to above-mentioned prior art existence; The utility model purpose is to provide a kind of fountain etching machine filter; Mainly be that crystal and other impurity in the later mixed chemical article of electronics nitration mixture (hydrofluoric acid, sulfuric acid, nitric acid) and TFT-LCD glass reaction are filtered, reach the purpose that improves the recovered acid cleanliness factor.
The technical scheme of the utility model is: a kind of fountain etching machine filter; Comprise the device body that is installed in backflow mouth of pipe place in the etching cabin and covers the whole backflow mouth of pipe; Said device body comprises support, is disposed with coarse strainer and fie screen on the said support from top to bottom.
As preferably, said support is made up of frame-saw and support bar.
As preferably, said support bar and frame-saw are hinged through connector.
As preferably, said support bar is the telescopic rod that length can be regulated.
As preferably, said fie screen and coarse strainer are removably connected on the support.
As preferably, said fie screen all is connected with frame-saw with bolt through press strip with coarse strainer.
As preferably, said fie screen and coarse strainer are processed by the PVC material.
As preferably, the aperture of said coarse strainer is φ 5, and the aperture of said fie screen is φ 2.
The beneficial effect of the utility model is: the utility model mainly is in etching machine etching cabin, to increase screen pack to carry out double-filtration: it mainly is to select for use coarse strainer to filter large granular impurity that one-level is filtered; Cascade filtration adopts fie screen to filter granule impurity, and the partial impurities in the acid solution of etching (mainly be silicate, and other impurity) is filtered, and manual regular is cleared up the impurity that filters out, and principle is comparatively simple, and is easy to operate.

The specific embodiment
A kind of embodiment as the utility model; Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; A kind of fountain etching machine filter comprises the device body that is installed in backflow mouth of pipe place in the etching cabin and covers the whole backflow mouth of pipe, and said device body comprises support; Said support is made up of frame-saw 1 and support bar 2; Said frame-saw 1 is the open rectangular configuration in rear end that preceding end carriage and left and right sides curb girder are formed, the preceding end carriage of frame-saw 1 and junction, etching cabin be provided with two with suitable inclined-plane, etching cabin, two inclined-planes are mutually 90 and spend; Wherein adjacent with frame-saw 1 bottom surface inclined-plane and frame-saw 1 bottom surface are mutually 120 degree, and the rear end of the left and right sides curb girder of said frame-saw 1 is provided with the inclined-plane that is mutually 148.3 degree with frame-saw 1 bottom surface.In addition, the otherwise designed as the case may be of the angle between the angle between each inclined-plane and each inclined-plane and the bottom surface.
Said frame-saw 1 inside is provided with two-layer step; Two-layer step is disposed with coarse strainer 3 and fie screen 4 from top to bottom; The aperture of said coarse strainer 3 is φ 5; The aperture of said fie screen 4 is φ 2, and the press strip 5 of said fie screen 4 through pushing down its edge and bolt are on lower floor's step, and the press strip 5 of said coarse strainer 3 through pushing down its edge and bolt are on the step of upper strata.Said coarse strainer 3 is processed by the PVC material with fie screen 4, and corrosion resistance is strong, long service life.
Be respectively equipped with fastener 6 on the left and right sides curb girder of said frame-saw 1, said fastener 6 is installed on the end face of frame-saw 1 through bolt.As shown in Figure 4, said device body links together with etching machine through this fastener 6.
Said support bar 2 is two; And laying respectively at the bottom of frame-saw 1 left and right sides curb girder, support bar 2 is hinged through connector 7 with frame-saw 1, so that regulate the angle of frame-saw 1 as required; The telescopic rod that support bar 2 can be regulated for length is so that regulate the height of frame-saw 1 as required.
