Description

Combined multi-core water purifier

Technical field:

The utility model relates to a combined multi-core water purifier.

Background technique:

The current water purification equipment includes filter elements, sand filters, reverse osmosis and ultrafiltration, etc. The filtration processes are: barrier filtration, adsorption filtration, and ion exchange filtration. Insufficiency of a single filtration process: the disadvantage of sand filtration (adsorption filtration) is that the filtration precision is not high, and the disadvantage of the filter element is that the impurities are absorbed by the filter element and are not washed in time, which is easy to produce algae and bacteria. The disadvantage of ion exchange filtration is that the filtration effect is affected for macromolecular substances and water with relatively high turbidity, and the surface of ion carriers is often wrapped by macromolecular pollutants, which seriously affects the efficiency of ion exchange. The disadvantage of barrier filtration is that it cannot remove pollutants in the form of ions, and the pores of the filter material are often blocked by pollutants, and bacteria and algae will breed over time, causing secondary pollution. At present, the method of pickling is mostly used to clean the surface of the filter material, but the maintenance is inconvenient and affects the service life of the filter material.

Invention content:

The purpose of the utility model is to provide a combined multi-core water purifier with a wide decontamination range, many types and a long service life. The purpose of this utility model is achieved by the following structure: the utility model is a combined multi-core water purifier, the upper tank body and the lower tank body are connected as a whole by connecting flanges, and the center of the upper tank body is a water distributor , the water distributor is equipped with a filter element, and the upper tank outside the filter element is filled with water purification filter material. The directly connected water outlet is connected to the first backwash water inlet, the water distributor is connected to the second backwash water inlet installed on the side wall of the lower tank body, and a base is arranged at the bottom of the lower tank body. The utility model adopts the combination mode of three filter structures. To achieve the mutual compensation of the shortcomings between the processes, the more important thing is that the application of the triple filtration process has a wider range of different polluted water quality, and it improves the service life of the water purification equipment. This combination improves the filtration accuracy of the sand filter, and the outer surface of the filter element is wrapped by the sand filter and the filter material, and the inner wall of the tank is not easy to produce bacteria, algae, and microorganisms to avoid secondary pollution. The purification principle of the utility model is as follows: the raw water flows from the water inlet through the water distribution grid plate, flows into the water purification filter material area, and undergoes adsorption or ion exchange filtration, and the filtered water passes through the filter element for deep filtration, and then flows into the lower tank after filtration , flows out through the outlet. Double backwash principle: One backwash: water enters the filter element from the first backwash water inlet, penetrates into the filter material area through the filter element wall, and flows out from the water inlet through the water distribution grid plate. So as to achieve the effect of discharging the pollutants in the pores of the surrounding wall of the filter element and flushing the filter material. Double backwashing: water flows into the water distributor from the second backwashing water inlet, enters the filter material area, and flushes the filter material. The polluting substances are washed away, and the washed water passes through the water distribution net plate and flows out from the water inlet.

Detailed ways:

The utility model shown in Figure 1 is a combined multi-core water purifier, the upper tank body 13 and the lower tank body 7 are connected to form a whole by connecting flanges, as shown in Figure 2, the center of the upper tank body 13 is The water distributor 9 is equipped with a filter element 12 outside the water distributor 9, and the upper tank body 13 outside the filter element 12 is filled with a water purification filter material 5, and the upper part of the upper tank body 13 is provided with a water distribution net plate, and the top of the upper tank body 13 has a water outlet , the side wall of the lower tank body has a water outlet 6 directly connected with the lower tank body 7 and a first backwash water inlet 10, and the water distributor 9 communicates with the second backwash water inlet 11 installed on the side wall of the lower tank body 7 , the base 8 is arranged at the bottom of the lower tank body 7 . The filter core 12 can be composed of multiple pieces. As shown in Figure 3, the water purification method combined with the filter material and the polymer filter element triple purification process (adsorption, exchange, and barrier) improves the quality of water purification. Double backwashing process is adopted. That is, one-stage backwashing: water enters the interior of the filter element 12 from the first backwashing water inlet 10, penetrates into the filter material 5 area through the surrounding wall of the filter element 12, and flows out from the water inlet 1 through the water distribution grid plate 2. Thereby, the pollutants in the pores on the wall of the filter element 12 are discharged and the effect of washing the filter material is achieved. Double backwash: water flows into the water distributor 9 from the second backwash water inlet 11, enters the filter material 5 area, and flushes the filter material 5, and at the same time utilizes the friction between the filter material and the outer wall of the polymer filter element 12 during flushing The function is to wash away the pollutants attached to the outer wall of the polymer filter element 12, and the water after washing flows out from the water inlet 1 through the water distribution grid plate 2.
