Further, nuts are arranged above and below the baffle, the nuts are in threaded connection with the corresponding connecting rods, and the baffle is sleeved on the connecting rods in a sliding mode, so that the height of the baffle is adjusted.
And furthermore, water holes are uniformly distributed on the baffle plate.
Furthermore, an annular backwashing pipe is arranged in the tank body, backwashing water caps are uniformly distributed on the upper surface of the annular backwashing pipe, and the annular backwashing pipe is connected with a water pump through a pipeline with a first valve.
Furthermore, the annular backwashing pipe is connected with an air pump through a pipeline with a second valve, and the air pump and the water pump are symmetrically arranged on two sides of the annular backwashing pipe respectively.
Further, the annular backwashing pipe is positioned 10cm above the water cap plate.
Furthermore, the cross section of the annular backwashing pipe is rectangular, so that the installation of a backwashing water cap is convenient.
Compared with the prior art, the invention has the following advantages:
the invention disperses the backwashing water by adding the water baffle, and simultaneously adds the branch pipes to guide the backwashing water to the edge of the water cap plate, so that all the filter materials can be flushed into a suspended state by the backwashing water, and the intercepted impurities are stripped off and taken out by the backwashing water by virtue of the shearing force and mutual friction force of the water streams among the filter material particles, thereby realizing the comprehensive backwashing of the filter materials, increasing the backwashing quality, and simultaneously, the invention can adjust the water yield and the water outlet speed of the branch pipes by controlling the height of the baffle;
according to the invention, the annular backwashing pipe is additionally arranged above the water cap plate, water and air are alternately introduced to the bottom of the filter material through the annular backwashing pipe, air bubbles rise through gaps of the filter material to expand and contract gaps, and filter material particles rise, rotate and collide, so that impurities adsorbed on the filter material fall off and are discharged along with backwashing water, and meanwhile, the annular backwashing pipe is positioned at the edge position of the water cap plate, so that the filter material at the boundary can be fully backwashed.
