Movable spray filter

Abstract

The present invention discloses a mobile spraying filter in the field of water-treating equipment. The mobile spraying filter comprises a sealed tank body; wherein, an inflow pipe and a filtering outflow pipe are respectively arranged on the top and bottom of the tank body; an underlayer, a filter material separator, a filter material layer and an escaping material prevention mechanism are arranged in the tank body orderly from bottom up; an upper hydraulic cylinder and a lower hydraulic cylinder are vertically arranged at the center of the tank body; the upper hydraulic cylinder is extended downwards into the tank body; a piston is fitted in the upper hydraulic cylinder; the piston rod of the piston is extended out from the lower end of the upper hydraulic cylinder; the lower hydraulic cylinder is extended upwards into the tank body; a hollow floating shaft is fitted in the lower hydraulic cylinder; the lower end of the piston rod is coaxially connected with the floating shaft; at least one pivoted arm is arranged on the lateral side of the floating shaft positioned in the filter material layer; the pivoted arm, which is extended into the filter material layer, is provided with spouts which drive the pivoted arm to rotate and are communicated with the cavity of the floating shaft; the lower hydraulic cylinder is connected with a backwashing inlet pipe; and the upper hydrauliccylinder is connected with a control pipe. The mobile spraying filter, which has the advantages of simple control and convenient management, can save energy and is applicable to various water-treating places.

Description

technical field [0001] The invention relates to water filtering equipment for stirring and backwashing filter material, and belongs to the technical field of water treatment. Background technique [0002] Backwashing and regeneration of the filter material of various existing filtering equipment, the backwashing power mainly depends on mechanical power or aeration backwashing, and the structure type is; [0003] One is: mechanical agitation type; the mechanical agitation type backwash filter mainly includes an upright sealed tank body with a water inlet pipe on the top of the tank body, and the water inlet pipe is respectively connected to the sewage inlet valve and the backwash water outlet valve , the bottom of the tank body is provided with a filter outlet pipe connected to the purified water outlet valve, the filter outlet pipe extends into the cushion layer set at the bottom of the tank body, a filter material partition is arranged above the cushion layer, and the filte...

AI Technical Summary

Problems solved by technology

[0006] 1. Energy consumption: generally 100m 3 / h filter stirring power is 18KW

[0007] 2. High manufacturing cost; maintenance platform, motor, reducer, stirring shaft, coupling, packing box, connection port, connection seat cost, etc.

[0009] 4. Transmission: The mechanical power is externally introduced into the container, and the sealing is difficult to ensure, and running, popping, dripping, and leaking occur from time to time

[0010] 5. Mechanical failure; motor gap running, belt tightness, reducer oil leakage, packing water leakage, motor, reducer self failure

[0011] 6. Noise; noise generated by motor and reducer

[0012] 7. The amount of maintenance is large; the wearing parts are replaced regularly, and the appearance of the equipment is not clean

[0013] 2. Disadvantages of air source backwashing type:

[0014] 1. Air machine energy consumption; generally 100m 3 / h filter, the gas volume per minute is 4.3m 3 , motor power is 7.5KW

[0015] 2. The air distribution is uneven; there is a dead zone in the backwash, the stirring is not strong, the cleaning is not clean, and the backwash water consumes a lot

[0016] 3. Sewage is filtered and aerated with oxygen; it is easy to corrode pipeline equipment, exhaust exhaust, and pollute the air

[0017] 4. The air machine room is noisy and has many auxiliary facilities
