Spraying device for preventing liquid from adhering to pipe walls for long time

Abstract

The invention discloses a spraying device for preventing liquid from adhering to pipe walls for a long time. The spraying device comprises a box body, an electric sliding block sliding groove with a leftward opening is formed in the top surface of the box body, an electric guide rail is fixedly arranged on the bottom surface of the electric sliding block sliding groove, and the electric guide railis in power sliding connection with an electric sliding block; the right end of the electric sliding block is provided with an angle adjusting groove which is through up and down and provided with aleftward opening, and the left end wall of the bottom end of the angle adjusting groove is fixedly provided with a slope supporting block, the bottom end of the slope supporting block is fixedly provided with a rotating plate shaft, and the front and rear ends of the rotating plate shaft are rotatably connected with the left end of a rotating supporting plate; and an angle adjusting air bag is fixedly connected between the bottom face of the rotating supporting plate and a top end slope of the slope supporting block, a spraying head device is fixedly arranged on the top face of the rotating supporting plate, and two inclined block sliding grooves with rightward openings are formed in the left end wall of the electric sliding block sliding groove in a front-back symmetry manner. Residual liquid in a used infusion tube can be automatically collected in time through the pressure difference, and the spraying angle can be freely adjusted.

Description

technical field [0001] The invention relates to the related technical field of spraying or atomizing devices, in particular to a spraying device that prevents liquid from adhering to pipe walls for a long time. Background technique [0002] The injection device is a vacuum acquisition device that uses fluid to transfer energy and quality. It uses a water flow with a certain pressure to spray out through nozzles that are symmetrically arranged with a certain side slope and converge on a focal point. Due to the extremely high flow rate of the jet water, the pressure energy is converted into velocity energy, and the pressure in the suction area is reduced to generate a vacuum. [0003] The infusion tube of the injection device at the present stage will not be automatically cleaned in time after use, and the liquid residue will adhere to the inner wall of the tube, which will cause the tube wall to corrode or accumulate and block, so that the injection cannot be carried out smoo...

Problems solved by technology

[0003] The infusion tube of the injection device at the present stage will not be automatically cleaned in time after use, and the liquid residue will adhere to the inner wall of the tube, which will cause the tube wall to corrode or accumulate and block, so that the injection cannot be carried out smoothly, and when the type of injection liquid is different, the liquid needs to be replaced manually The type of supply also needs to be replenished by adding liquid manually, which is inefficient and time-consuming, and the spray angle is fixed and cannot be adjusted freely
