Background

Along with the continuous acceleration of the industrialized process and the urbanization process in China, more and more waste water is generated in the industrial, commercial and civil fields, the waste water is required to be filtered during treatment to reduce the content and turbidity of suspended matters, meanwhile, because of the serious shortage of water resources in China and the increase of the environmental protection supervision, the yield of seawater desalination and the yield of water treatment in enterprises are continuously increased, a seawater desalination device and most of reclaimed water treatment devices are required to use a water filter, the conventional water filter generally takes quartz sand, a metal filter core or a non-metal high polymer material as a filter core material, the non-soluble suspended matters are blocked by the gaps of the filter core material after water enters the filter, the purposes of isolating and removing the suspended matters are achieved, but the suspended matters are gathered on the surface of the water inlet side of the filter core material in the filtering process, and the pressure difference between the two sides of the filter core is, the resistance is increased during water filtration, and the efficiency and the effect of water filtration are reduced.

At present, water treatment devices in China are all based on the pressure difference and backwashing principle, suspended matters are gathered on the water inlet side of a filter element material in the filtering process, the pressure on the water inlet side of the filter element material is continuously increased, the backwashing work opposite to the filtering process needs to be executed when the filtering resistance is increased to a certain value, the suspended matters gathered on the water inlet side of the filter element are reversely washed by using clean water, the performance of the filter element is recovered by the reverse washing, the filter is enabled to reach the design performance again, and the following defects and shortcomings exist in the working principle:

1. In the back washing process, an additional differential pressure monitoring device, a back washing water tank, a back washing pump and a valve for switching the water flow direction are required to be arranged, so that the equipment investment is increased undoubtedly;

2. The back washing process also needs to occupy the normal working time of the filter, and according to different application fields and water quality, the back filtering process usually needs to occupy 5% -10% of the working time of the filter, so that the effective working time of the equipment is greatly reduced, and the benefit of the equipment is reduced;

3. Although the pressure difference of part of filtering equipment after back washing meets the requirement, the filtering effect is obviously reduced, and the water quality after filtering is often reduced, so that the water quality is reduced;

4. The conventional backwashing device cannot solve the problem that the filter element is blocked due to the growth of microorganisms in the filter.

The high-efficiency water filter disclosed by the invention can solve the problems, avoid backwashing time, reduce backwashing equipment, increase equipment benefit, generate continuous and stable filtering effect in the filtering process, and also can be optionally matched with functions of sterilizing and killing microorganisms.

Disclosure of Invention

The invention aims to provide a high-efficiency water filter to solve the problems in the prior art.

In order to achieve the purpose, the invention provides the following technical scheme:

The utility model provides a high-efficient water filter, includes the filter vat, the inside filter core that is provided with of filter vat, filter core a week is provided with the aeration pipe, filter vat upper end one side is provided with the inlet tube, the filter vat bottom is provided with the outlet pipe, the filter vat top is provided with the gas outlet, filter vat one end is provided with the aeration circulating pump.

A high-efficiency water filter adopts the aeration principle in the sewage treatment process to continuously clean the water inlet side surface of a filter element in a filter barrel, suspended matters on the water inlet side of the filter element can not be gathered all the time, thereby achieving the purpose that the filter can continuously work, avoiding the time waste caused by the back washing process, sewage enters the filter barrel from a water inlet pipe, water is driven to flow into the filter element from the outer surface of the filter element under the action of pressure difference, the filtered water is gathered in the filter element and then flows out of the high-efficiency water filter through a water outlet pipe, the filtering process is finished, in the filtering process, bubbles generated by an aeration circulating pump are introduced into an aeration pipe, the aeration pipe on the lower part of the filter element continuously emits bubbles with specific flow and size, the bubbles form disturbance with the outer surface of a conical filter in the rising process, the shearing force for removing the suspended matters on the outer surface on the, the pressure difference between the inside and the outside of the filter element is stabilized in a specific range, and the continuity and the stability of the water purification work are kept.

The filter element is a metal filter screen with an inverted cone shape.

The filter element of the inverted cone-shaped metal filter screen can generate shearing force with air bubbles discharged by the air explosion pipe.

The explosion pipe has a plurality of, place in the lower part of filter core.

The plurality of air blasting pipes are beneficial to generating enough air bubbles, and the air blasting pipes are arranged at the lower part of the filter element and are beneficial to generating enough buoyancy and shearing force by the air bubbles to wash suspended matters and prevent the suspended matters from being gathered on the outer surface of the filter element.

One side of the explosion gas circulating pump is connected with a first circulating pipe, the first circulating pipe penetrates through the filter vat to be communicated with the explosion gas pipe, the upper end of the explosion gas circulating pump is connected with a second circulating pipe, and the second circulating pipe is in sealing connection with the gas outlet.

Above-mentioned gas gets into the gas burst pipe through first circulating pipe from exploding the gas circulating pump, explodes the gas circulating pump cooperation and explodes the gas pipe and can produce specific gas volume and bubble size of exploding, and the bubble gets into the filter vat and filters sewage, then rises and pass through gas outlet, second circulating pipe in proper order, gets into the gas circulating pump of exploding once more, so the circulation produces the clean effect that lasts to sewage.

The water outlet pipe is communicated with the bottom of the filter element.

The water filtered by the filter element flows out from the bottom of the filter element and is collected by the water outlet pipe.

the diameter of the bubble is a, the range of the a is 1 mm-5 mm, the taper of the filter element is b, the range of the b is 5-20 degrees, the flow rate of the bubble is c, and the range of the c is 200L/h-800L/h.

The pressure difference value of the inlet and the outlet of the filter barrel is delta F, and the relation between delta F and a, b and c is as follows: Δ F ═ 0.67 × 10 ⁶*COS(b)/((1000+c)*(1000+a³))。

The speed of the suspended solid gathering on the filter core can be decided to the tapering of filter core, the buoyancy of bubble and the flow of bubble, and then decides the concentration of filter core in inlet tube one side, reachs the pressure differential of the inside and outside surface of filter core, and when the pressure differential of the inside and outside surface of filter core kept a comparatively stable value, a high-efficient water filter can last stable output water purification, has avoided the back flush process, can show the operating efficiency who improves a high-efficient water filter.
