Pipeline spraying equipment

Abstract

The invention provides pipeline spraying equipment, and relates to the field of pipeline machining. The pipeline spraying equipment comprises an injection molding machine, a spraying mechanism, a grinding mechanism and a guide plate, a support is arranged on the outer wall of the bottom end of the injection molding machine, a discharging opening is formed in the outer wall of one end of the injection molding machine, the spraying mechanism is arranged on the outer wall of the discharging opening, a spraying pipe which is annularly distributed is arranged on the inner wall of the spraying mechanism, a rotating shaft is arranged on the inner wall of the spraying pipe, an output shaft of the rotating shaft is connected with a rotating motor through a coupler, a rotating roller is arranged on the outer wall of the rotating shaft, the outer wall of the rotating roller is connected with the grinding mechanism, the inner wall, close to the rotating roller, of the spraying pipe is connected with the guide plate, and a spray head is arranged on the outer wall of the bottom end of the spraying pipe. According to the pipeline spraying equipment, when an extrusion layer makes contact with the spray head, grinding blocks on the extrusion layer can smash small caking particles, a small part of chemical powder adhering to the pipeline spraying equipment can be vibrated to fall off, and the self-cleaning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline processing, in particular to pipeline spraying equipment. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. The pipe production line is an assembly line for pipe production. The main configurations include: automatic feeding machine, single / twin screw extruder, extrusion die, vacuum sizing spray box, tractor, cutting machine, stacker, spra...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a pipeline spraying equipment, which solves the production needs that the simple spraying process of pipeline processing cannot solve the actual situation. Before the pipeline injection molding, it is necessary to spray chemical additives on the surface of the pipeline that has not yet been finalized. In order to change the properties of the surface of the pipeline, the amount of chemical additives added must be kept within a certain range, and the surface of the pipeline needs to be sprayed evenly. If the spraying is uneven, the effect of the additives will be affected. The powdered chemical additives will last for a long time. It is also easy to agglomerate after placing it, which will affect the uniformity of the powder, and in severe cases, it will block some nozzles and affect the quality of the pipe forming.
