Abstract
The invention discloses a high-efficiency backwashing apparatus. The high-efficiency backwashing apparatus comprises a backwashing pipeline composed of a water storage tank (1), a filter vat (2), and a ceramic filter (4) which are successively connected; the water storage tank is communicated with an air compressor (5) used for providing compressed air; and the tail end of the backwashing pipeline, which is inserted into the ceramic filter, is provided with a cone nozzle (3). Beneficial effects are that: compressed air provided by the air compressor is delivered into backwashing water, so that pressure of the backwashing water is increased, and backwashing effect is improved; a one-way valve is arranged between the water storage tank and the air compressor so as to prevent back flow of the compressed air into the air compressor when the air compressor is turned off; and the cone nozzle arranged on the tail end of the backwashing pipeline, which is inserted into the ceramic filter, is capable of ensuring that water flow is provided with higher pressure via compression, and higher washing force is provided.
Description
Technical field
The present invention relates to ceramic filter, particularly relate to the efficient back purge system for ceramic filter.
Background technology
Ceramic filter is a kind of equipment for separating liquid from solid efficiently, and current product is applied to iron ore concentrate, copper concentrate, lead concentrate, aluminium concentrate, Gold Concentrate under Normal Pressure, fluorite ore Deng Ge great bargh widely for filtering.The operation principle of ceramic filter is: under the effect of pressure difference, and when suspension is by filter medium, particle is trapped within dielectric surface and forms filter cake, and liquid is then flowed out by filter medium, reaches the object of Separation of Solid and Liquid.
Ceramic filter, in running, when the full filter residue of filter plate absorption, after first having scraped material by scraper, then rinses filter plate, is rinsed out by the fine particle got lodged in filter plate hole, facilitate next step suction to operate.If backwashing water pressure is inadequate, does not then reach backwash effect, time serious, may ceramic wafer be blocked, cause spare part to scrap.
Summary of the invention
The technical problem to be solved in the present invention is the object that the existing back purge system for ceramic filter exists that hydraulic pressure does not reach backwash not, even blocks ceramic wafer time serious, provides a kind of efficient back purge system that can provide enough pressure for this reason.
Technical scheme of the present invention is: efficient back purge system, it comprises the counter-flushing pipeline be made up of the water tank be communicated with successively, filter vat and ceramic filter, water tank is also communicated with and provides compressed-air actuated air compressor, the end that described counter-flushing pipeline stretches into ceramic filter is provided with conical nozzle.
The invention has the beneficial effects as follows the pressure improving backwashing water by passing into the compressed air provided by air compressor in backwashing water, enhance the effect of backwash, between water tank and air compressor, be provided with check valve be back to when air compressor quits work in air compressor to prevent compressed air, the nozzle stretching into the counter-flushing pipeline end in ceramic filter ensure that current access stronger pressure through compression energy, provides larger flushing ability.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
In figure, 1, water tank, 2, filter vat, 3, conical nozzle, 4, ceramic filter, 5, air compressor, 6, check valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the present invention includes the counter-flushing pipeline be made up of the water tank 1 be communicated with successively, filter vat 2 and ceramic filter (4), water tank is also communicated with and provides compressed-air actuated air compressor 5, the end that described counter-flushing pipeline stretches into ceramic filter is provided with conical nozzle 3.
Water tank is sealing, and be the water source of backwash, current flow through filter vat to ceramic filter from water tank, and filter vat carries out filtration treatment to current, reduces impurities in water.
In order to make backwash effect better, a certain proportion of acid solution can be added in water, this acid solution is stored in acid solution bucket, pipeline is provided with below acid solution bucket, this pipeline is connected with the counter-flushing pipeline between filter vat 2 and ceramic filter 4, makes to flow through in the backwashing water below acid solution bucket be mixed into acid solution and finally flow in ceramic filter its cleaning.
When quitting work to prevent air compressor, compressed air is back in air compressor, can be provided with check valve 6 between water tank and air compressor.
The present invention is work like this: start air compressor, compressed air is mixed in water tank and flow to filter vat through water tank, filter vat filters current, removes impurity, then flows to ceramic filter, when entering ceramic filter and being inner through a conical nozzle, this nozzle surface is distributed with some spray orifices, and current are through spray orifice flow path constriction thus obtain larger pressure, and current attenuate, stronger to the impulsive force of ceramic filter inside, developing result is better.
Claims (1)
1. efficient back purge system, it comprises the counter-flushing pipeline be made up of the water tank be communicated with successively (1), filter vat (2) and ceramic filter (4), water tank is also communicated with compressed-air actuated air compressor (5) is provided, it is characterized in that the end that described counter-flushing pipeline stretches into ceramic filter is provided with conical nozzle (3).
