Description

Laminated filter

Technical Field

The invention relates to the technical field of sewage treatment, in particular to a laminated filter.

Background

Along with the rapid development of national socioeconomic, the destruction brought by water pollution to the environment influences more and more seriously, carries out sewage treatment and is reluctant, and among various sewage filtration equipment, lamination formula filter is because of its filter effect is good, and area is little, and the working costs is low and widely used, and lamination formula filter work can be divided into two kinds: firstly, in the filtering stage, water flow enters the filter through the filtering water inlet, the filtering lamination is tightly pressed together under the action of spring force and water force when passing through the filtering lamination, impurity particles are intercepted at the lamination intersection, and filtered water flows out from the main channel of the filter; and in the back washing stage, the water flow direction is changed, the spring on the filter element is pushed open by water pressure, small pores among all the laminations and the laminations are loosened, the nozzle positioned in the center of the filter element sprays water along a tangent line to enable the laminations to rotate, and solids trapped on the laminations are washed out under the washing action of water flow and the centrifugal action of high-speed rotation of the laminations.

Firstly, after the laminated filter filters sewage every time, the intercepted impurity particles are often clamped between two laminated sheets, in order to save water resources, backwashing is basically carried out after multiple times of filtering, so that after each time of filtering, the water power disappears, the spring rebounds, the small gap between the laminated sheets is loosened, the impurity particles existing between the laminated sheets after filtering continuously change in position in the subsequent vibration of elastic rebounding, the impurity particles possibly enter the laminated sheet ring along the channel at the moment, and when the sewage is filtered next time, the impurity particles are discharged along with the filtered water, so that the sewage filtering precision is limited.

Secondly, impurities trapped in the filtering process may have viscosity, so that the two laminated sheets are bonded together after entering between the laminated sheets, then the two laminated sheets bonded together cannot be separated by water flow impact force in the backwashing process, the impurities between the two laminated sheets cannot be cleaned, and finally the bonded laminated sheets are invalid, so that the filtering effect is reduced, if the backwashing water power is too small, the impurities trapped after one-time filtering are too much, at the moment, the gravity of the laminated sheets is too large, the backwashing water power cannot rotate the laminated sheets, so that the laminated sheets can only be cleaned in the direction opposite to the spray head, and other positions cannot be considered, so that the rinsing effect is reduced; simultaneously, in the filtration stage, the impact force that one side that is close to the sewage entry receives sewage to gush in is far away from sewage entry one side and will be far more for the lamination sewage treatment volume that is close to sewage one side will be big, and is the same when back flush stage is to both sides cleaning power, causes the cleaning dynamics that is close to sewage entry one side then not enough, makes the washing unclean, and the too much washing of opposite side causes the waste of water resource.
