Water filtering device of water mist sand blasting machine

Abstract

The invention relates to the technical field of filtering devices, and discloses a water filtering device of a water mist sand blasting machine, the water filtering device comprises a barrel body, theupper end of the barrel body is connected with a sealing head, a partition plate is fixedly arranged in the barrel body, the partition plate divides the barrel body into a water inlet chamber at thelower part and a filtering chamber at the upper part, a plurality of through holes are formed in the partition plate, the upper ends of the through holes are respectively connected with vertical filter elements, the upper ends of the filter elements are connected with movable pressing plates, each filter element is fixed in the filtering chamber through the pressing plate and a pressing screw connected between the partition plate and the pressing plate; the water inlet chamber is connected with a water inlet pipe, and the wall of the barrel of the filtering chamber is connected with a water outlet pipe; and a water baffle plate used for delaying a water flow to impact the filter elements is arranged on the pipe orifice part, facing one end of the interior of the filtering chamber, of the water outlet pipe. According to the invention, the reliability of the water filtering device under a high-pressure application occasion is improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of filtering devices, in particular to a water filtering device for a water mist sandblasting machine. Background technique [0002] When developing a new type of water mist sandblasting machine, in order to enable the water mist sandblasting machine to use fire water or Yangtze River water, it is necessary to use a water filter to prevent routine blockage or damage of pipelines, motor pumps and nozzles, and reduce Perform maintenance work on blasting pipes and nozzles. However, the current commercially available conventional water filter is prone to deformation of the internal filter element of the water filter under the water pressure of 1.0Mpa, resulting in poor filterability and frequent maintenance, which affects the overall use of the water mist sandblasting machine life, and the maintenance cost is also relatively high. Contents of the invention [0003] In order to solve the above problems, the p...
