Abstract

The utility model relates to a large diatomite filter used for electrolyte filtering. A sealed tank body of the large diatomite filter is horizontally arranged; one side of a tank cover is provided with a filter element lead-out bracket; the upper part of the lead-out bracket is a horizontal slideway, the horizontal slideway is provided with a vertical slide bar, the lower end of the slide bar is connected with the outer side of the tank cover; the inner side of the tank cover is connected with a filter element by two suspension rods horizontally arranged; the filter element comprises 46 filter screens; and the filter screen comprises a polygonal slot frame, two side surfaces of the filter screen are respectively covered with screen meshes to form a hollow filter screen, the slot frame at the bottom of the hollow filter screen is internally provided with a liquid outlet which is communicated with a filtrate branch pipe, and the filtrate branch pipe is communicated with a liquid outlet pipe. The large diatomite filter takes diatomite as a filter medium, and is attached on the wall of the filtering screen mesh by utilizing negative pressure, the characteristic of micropore of the diatomite can adsorb fine impurities and stop the passing of the fine impurities, thus filtering the electrolyte, and the design of adoption of a plurality of hollow filter screen sheets can enlarge the surface area of filtering, and increase the filtering speed so as to meet the requirement of fast production; the filtering precision is improved to be 1Mu; and the use cost is low.

Description

Large-scale diatomaceous earth filter

Technical field

The utility model relates to the diatomaceous earth filter that is used for electrolyte filtering.

Background technology

In the production technology of high-precision electronic Copper Foil, the filter effect of electrolyte is one of its key index, and filtering accuracy will reach 1 μ, and existing manufacturing enterprise adopts the filter bag type filter to filter more, the precision of filtering does not reach requirement, and the filter bag consumption is very big and cause cost to increase.

Summary of the invention

Do not reach the problem of requirement in order to solve existing filter bag type filter energy consumption height, the filtering accuracy that is used for electrolyte filtering, the utility model provides a kind of horizontal large-scale diatomaceous earth filter.

Concrete technical solution is as follows:

Large-scale diatomaceous earth filter comprises cylindric sealed shell of tank, cover and filter core.

Described sealed shell of tank is horizontal installation, and the sealed shell of tank side is provided with two inlets, and the top is provided with two exhaust outlets, and the bottom is provided with two evacuation ports, and both sides are separately installed with the horizontal slip track in the sealed shell of tank; Cover one side is provided with filter core and derives support; Described derivation support top is horizontal slideway, and horizontal slideway is provided with more than one vertical slide bar, and the slide bar lower end is connecting the cover outside; The cover inboard is connecting filter core by two horizontally disposed pegs, and two pegs cooperate with both sides sliding rail in the sealed shell of tank respectively; Described filter core comprises the filter screen more than 30; Described filter screen comprises polygon groove frame, and the two sides of polygon groove frame are wrapped respectively and are provided with silk screen and form hollow filter screen, are provided with liquid outlet in the base channel frame of hollow filter screen, and liquid outlet is being communicated with the filtrate arm, and the other end of filtrate arm is being communicated with drain pipe; Described drain pipe extends to the sealed shell of tank outside.

Described silk screen aperture is 200 orders.

Described peg bottom is respectively equipped with two pulleys, and the logical pulley of peg cooperates slip with sliding rail.

The utility model adopts diatomite as filter medium, utilize negative pressure to adhere to and filter on the gauze wall, the characteristic of diatomite micropore can be adsorbed the prevention fine impurities and be passed through, thereby electrolyte is filtered, design adopts the hollow filtering net plate of most amounts can increase the filter table area, improves the rate of filtration and produces quick needs to satisfy.

The utility model is compared with prior art products has following aspect advantage:

1, the utility model adopts diatomite as filter medium, utilize negative pressure to adhere to and filter on the gauze wall, the characteristic of diatomite micropore can be adsorbed the prevention fine impurities and be passed through, thereby electrolyte is filtered, design adopts the hollow filtering net plate of most amounts can increase the filter table area, improves the rate of filtration and produces quick needs to satisfy.

2, precision height of the present utility model, filtering accuracy has been brought up on 1 μ.

3, the utility model is easy to operate, the filter material replacement cycle is long, and use cost is low.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

Referring to Fig. 1, large-scale diatomaceous earth filter comprises cylindric sealed shell of tank 1, cover 12 and filter core 2.

Sealed shell of tank 1 is horizontal installation, and the sealed shell of tank side is provided with two inlets 8, and the top is provided with two exhaust outlets 6, and the bottom is provided with two evacuation ports 5, and axially the other end is provided with purified water inlet 7, and both sides are separately installed with horizontal slip track 17 in the sealed shell of tank.Cover 12 1 sides are equipped with filter core and derive support 3; Deriving support 3 tops is horizontal slideway, and horizontal slideway is provided with more than one vertical slide bar 15, and slide bar 15 lower ends are connecting cover 12 outsides; The cover inboard is connecting filter core by two horizontally disposed pegs 11, and two pulleys 16 installing by the bottom respectively of peg 11 cooperate slips, slip during with the derivation of cooperation support with sliding rail 17 in the sealed shell of tank; Filter core 2 comprises 46 filter screens.

Referring to Fig. 2 and Fig. 3, filter screen comprises polygon groove frame 14, and the two sides of polygon groove frame 14 are wrapped respectively and are provided with the hollow filter screen of silk screen 10 formation, and the silk screen aperture is 200 orders; The both sides corresponding with two pegs 11 are separately installed with clip 9, by clip 9 filter screen are mounted on the peg 11.With a certain amount of super-cell of load, diatomite utilizes negative pressure to adhere on the screen pack wall as filter medium in the hollow filter screen; Be provided with liquid outlet in the base channel frame of hollow filter screen, liquid outlet is being communicated with filtrate arm 13, and the other end of filtrate arm 13 is being communicated with drain pipe 4; Drain pipe 4 extends to sealed shell of tank 1 outside.
