Abstract
The utility model discloses a kieselguhr precoating forward and backward blowing filtration device. The device comprises a filter, wherein a filter element sleeved with a filter bag is arranged in the filter, an inlet is formed in one side of the lower part of the filter, an outlet is formed in one side of the upper part of the filter, and a drain outlet is formed in the bottom of the filter. The device is characterized in that a compressed air inlet is also formed in the top of the filter, and an impulse valve is arranged on a pipeline for delivering compressed air. According to the kieselguhr precoating forward and backward blowing filtration device, the compressed air inlet and the impulse valve are arranged, so that when the filter element is blocked, the impulse valve is opened at first to forwards and backwards blow the filter element so as to remove dirt on the filter element, and thus, the filter element is prevented from being manually cleaned; and the device is simple, practical, convenient and quick.
Description
Technical field
The utility model relates to filter, specifically, is the positive back flushing type filter of diatomite precoating that is used for filtering copper-bath in producing about a kind of electrolytic copper foil.
Background technology
Diatomite is the siliceous organism sedimentary rock take opal as the essential mineral component, mainly is that the remains deposition of unicellular water plant diatom forms.It has the advantages that porous, surface area reach greatly chemical stability, is natural filter aid.
Diatomaceous earth filter is take diatomite as main medium, utilizes the trickle property of diatomite particle and the filter of the impurity such as the suspended particulate in the porous removal liquid, colloid.The filtering accuracy of diatomaceous earth filter is higher, can filter out bacterium and part virus under the normal operating conditions.
Be used for filtering the diatomaceous earth filter of copper-bath during existing electrolytic copper foil is produced, generally include filter cylinder, be provided with filter core in the cylindrical shell, copper-bath enters filter from the import of bottom, flows out from outlet behind filter element filtering.This kind filter because the impurity that filters down can stop up filter opening, causes filter efficiency to reduce in use, and cleans or more renew cartridge is cumbersome, therefore is necessary to be improved.
The utility model content
The purpose of this utility model just is to improve and has the existing above-mentioned shortcoming of diatomaceous earth filter and deficiency that is used for filtering copper-bath in the electrolytic copper foil production now, thereby provides a kind of diatomite precoating positive back flushing type filter.
The positive back flushing type filter of diatomite of the present utility model, comprise filter, its inside is provided with the filter core that cover has filter bag, below one side of filter is provided with import, top one side is provided with outlet, and the bottom of filter is sewage draining exit, wherein, the top of filter also is provided with the compressed air inlet, and carries compressed-air actuated pipeline to be provided with the pulsed valve.
The positive back flushing type filter of diatomite precoating of the present utility model, owing to be provided with compressed air inlet and pulsed valve, therefore can be when filter core occurs to stop up, come filter core is carried out positive blowback by unbalanced pulse formula valve, remove the dirt on the filter core, thereby avoid the artificial cleaning of implementing filter core, simple and practical, convenient and swift.

The specific embodiment
Below in conjunction with accompanying drawing, with specific embodiment the positive back flushing type filter of diatomite precoating of the present utility model is described in further detail.Should be understood that following examples are only for explanation the utility model but not for limiting scope of the present utility model.
As depicted in figs. 1 and 2, the positive back flushing type filter of diatomite of the present utility model, comprise filter 10, its inside is provided with the filter core 11 that cover has filter bag, and below one side of filter 10 is provided with import 12, and top one side is provided with outlet 13, the bottom of filter 10 is sewage draining exit 14, wherein, the top of filter 10 also is provided with compressed air inlet 15, and carries compressed-air actuated pipeline to be provided with pulsed valve 20.
Wherein, the import 12 of described filter 10 belows is used for to filter 10 interior conveying diatomite pre-coating solution or copper-baths to be filtered.
The sewage draining exit 14 of described filter 10 bottoms is used for discharging the dirt that filters down or unnecessary diatomite pre-coating solution.
The outlet 13 of described filter 10 tops is for delivery of after filtering copper-bath.
The positive back flushing type filter of diatomite precoating of the present utility model is equipped with control valve 120,130,140,150 before its import 12, outlet 13, sewage draining exit 14 and the compressed air inlet 15.Top one side of filter 10 also is provided with visor 16, is used for the inner case of Real Time Observation filter 10.
In addition, the top of the filter of the positive back flushing type filter of diatomite precoating of the present utility model also is provided with atmospheric valve 17.
Compressed air is provided by air tank 22, can be by pipeline with compressed air delivery to filter 10.Transfer pipeline is provided with Pressure gauge 23, and the top of filter 10 is provided with Pressure gauge 23 equally.
The diatomite pre-coating solution is stored in the precoating tank 30, is provided with infusion pump between precoating tank 30 and the filter 10.When using, at first open infusion pump, the diatomite pre-coating solution is sent in the filter 10, filter core 11 is carried out precoating.Observe the precoating situation by visor 16, after precoating was good qualified, opening controlling valve 140 made remaining pre-coating solution return precoating tank 30 and stirs, and treated next working cycles use.Then the valve 120,130 of the import 12 of opening filter 10 bottoms and outlet 13 makes copper-bath finish secondary filter through the filter core 11 of precoating in filter 10.
In the actual production process, the pressure before filtering with filter after the pressure reduction≤4kg of pressure the time, show that the dirt of deposition on the filter core 11 has affected normally carrying out of filtering, this time need carry out positive blowback, to remove the coarse grain foreign matter of failing on the filter core 11 by filter core.The flow process of positive blowback is as follows:
Close copper-bath imported valve 120 and outlet valve 130 on the filter 10, after the bottom valve 140 of unlatching atmospheric valve 17 and sewage draining exit 14 drains copper-bath, close atmospheric valve and bottom valve, and then opening the compressed air inlet valve makes compressed air enter filter 10, observe by visor 16, remaining copper-bath in the coarse fodder dirt on the crowded to the greatest extent filter core 11 of air to be compressed, make the coarse fodder dirt be pie, at this moment, layout is the positive blowback of pulsed to the pulsed valve at the compressed air valve in exit and import compressed air place through automatic control system, the coarse fodder dirt pie of observing on the filter core by the visor mouth breaks away from filter core, then open sewage draining exit and make its discharge, this moment, positive blowback circulation finished.
