Petreatment filter for water treatment system

Abstract

The invention relates to the technical field of sewage treatment, and discloses a pretreatment filter for a water treatment system. The pretreatment filter comprises a base, a filter screen, a water retaining dam and a conveying belt, water retaining walls are fixedly arranged at the two ends of the base, first trapezoidal convex blocks are fixedly arranged at the front end of the base, and firstsupporting columns are fixedly arranged at the rear ends of the water retaining walls; a second trapezoidal protruding block is fixedly arranged at the upper end of the first supporting column, a reciprocating lead screw is arranged between the first trapezoidal protruding block and the second trapezoidal protruding block, a cleaning plate is arranged on the rod wall of the lower end of the reciprocating lead screw, a worm wheel is fixedly arranged on the rod wall of the upper end of the reciprocating lead screw, a fixing block is fixedly arranged at the middle end of the first supporting column at the left end, a fixing plate is fixedly arranged at the middle end of the first supporting column at the right end, a first motor is fixedly arranged at the upper end of the fixing plate, a wormis fixedly arranged at the output end of the first motor, and the worm and two worm wheels are engaged. The garbage and large particles in sewage can be automatically fished out, and the filter screen can be automatically cleaned.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pretreatment filter used in a water treatment system. Background technique [0002] Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Before the existing sewage is purified, it is necessary to pre-treat the sewage, that is, to remove some large pieces of garbage or particles in the sewage. [0003] The existing sewage pretreatment is generally to manually salvage the garbage in the sewage, which leads to high work intensity and low work efficiency, and the sewage contains harmful substances, which is a serious hazard to the health of the salvage personnel. Because the sewage also contains a large amount of Large particles, which cause the sewage filter to be easily clogged. Contents of the invention [0004] The purp...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, the existing sewage pretreatment is generally to manually salvage the garbage in the sewage, resulting in high work intensity and low work efficiency, and the sewage contains harmful substances, which is harmful to the body of the salvage personnel. There are serious health hazards, because the sewage also contains a large number of large particles, which leads to the problem that the sewage filter is also easy to block, and a pretreatment filter for the water treatment system is proposed
