Description

Ultrafiltration equipment for drinking water

Technical Field

The utility model relates to the technical field of filtering equipment, in particular to drinking water ultrafiltration equipment.

Background

Ultrafiltration is a membrane separation technique that allows the solution to be purified and separated; the ultrafiltration membrane system is a solution separation device which takes ultrafiltration membrane wires as filter media and takes pressure difference at two sides of the membrane as driving force. The ultrafiltration membrane only allows the solvent, inorganic salt and micromolecular organic matters in the solution to permeate, and intercepts the suspended matters, colloid, protein, microorganisms and other macromolecular matters in the solution, thereby achieving the aim of purification or separation;

in the related art, the Chinese patent with the patent publication number of CN215756731U provides ultrafiltration treatment equipment for drinking water, which comprises a water storage tank, wherein a first filter tank and a second filter tank are arranged in the water storage tank from top to bottom, a first filter hole is formed in the bottom of the first filter tank, a dredging mechanism is further arranged at the bottom of the first filter tank, a second filter hole is formed in the bottom of the second filter tank, the dredging mechanism comprises a fixed sleeve and a rotating shaft, the fixed sleeve is fixedly connected with one side of the inner wall of the water storage tank, a sliding rod is slidably connected in the fixed sleeve, a disc is fixedly connected with the top of the sliding rod, a conical column is fixedly connected with the bottom end of the sliding rod, a baffle is further arranged on the outer wall of the bottom end of the sliding rod, and the spring is positioned between the fixed sleeve and the baffle, so that the technology can quickly and conveniently dredge the filter holes of untreated water, and the filter holes are extremely easy to be blocked by impurities when the untreated water is subjected to preliminary filtration;

however, in combination with the above related art, the inventor found that in the practical application process, the bottom of the first filtering tank in the technology is of a flat bottom structure, when the filtering hole is blocked, although the dredging mechanism can eject the impurity out of the filtering hole, the impurity still covers the hole opening of the filtering hole under the influence of water flow or returns to the filtering hole again, so that the dredging effect of the dredging structure in the technology is not obvious, and the filtering hole still has the risk of being blocked again.
