Water inlet pipeline filtering device for tower crane spraying machine

Abstract

The invention discloses a water inlet pipeline filtering device for a tower crane spraying machine. The water inlet pipeline filtering device comprises a shell; a circular cavity is formed in the shell. A water inlet pipe is connected below the inner wall of the circular cavity; a water outlet pipe is connected to the upper portion of the inner wall of the circular cavity, an annular filter screenis fixedly connected to the inner wall of the circular cavity, the annular filter screen and the inner wall of the circular cavity form an annular cavity, a plurality of scraping blades are connectedto the inner wall of the annular cavity in a sealed and sliding mode, and a driving mechanism for driving the scraping blades to slide on the inner wall of the annular cavity is mounted in the circular cavity. Particle impurities in a water source are filtered through the annular filter screen; particles are prevented from being pressurized into a nozzle along with a water source, and blockage ofspray orifices of the nozzle is prevented; when a hydrodynamic wheel rotates to accumulate force on a coil spring, and no water flow flows through the shell, the coil spring releases elastic force todrive an impeller to rotate, so that the scraping blades are driven to rotate, impurities on the annular filter screen are pushed, the annular filter screen is cleaned, and an automatic cleaning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of spraying machines, in particular to a water inlet pipe filter device for a tower crane spraying machine. Background technique [0002] The tower crane spraying machine pressurizes the water source connected to the water inlet pipe of the spraying machine into the outlet pipe connected to the tower crane arm when there is a lot of dust on the construction site, and sprays it out from the nozzle to reduce dust on the construction site deal with. [0003] In order to save water resources, the current tower crane spraying machine is often combined with the circulating water recovery system. The circulating water recovery system mainly collects, filters and precipitates the circulating water, but after the circulating water is treated, there are still some impurities in the water source. For example, sand and rust, these particles cannot flow out through the nozzle holes on the nozzle of the tower crane sprin...

[0003] In order to save water resources, the current tower crane spraying machine is often combined with the circulating water recovery system. The circulating water recovery system mainly collects, filters and precipitates the circulating water, but after the circulating water is treated, there are still some impurities in the water source. For example, sand and rust, these particles cannot flow out through the nozzle holes on the nozzle of the tower crane sprinkler, so that after the tower crane sprinkler pressurizes the water source in the circulating water recovery system, these particles will directly cause the nozzle holes on the nozzle to flow from the inside Blockage reduces the spray range effect of the nozzle. In addition, because the nozzle is installed at a high position, it is not easy to disassemble the nozzle, which further affects the dust reduction treatment effect on the construction site.
