A pipeline spraying equipment

Abstract

The invention provides a pipe spraying equipment, which relates to the field of pipe processing. The pipeline spraying equipment includes an injection molding machine, a spraying mechanism, a grinding mechanism and a guide plate. A support is provided on the outer wall of the bottom end of the injection molding machine, and a discharge port is provided on one end of the injection molding machine. The outer wall is provided with a spraying mechanism, the inner wall of the spraying mechanism is provided with annularly distributed nozzles, and the inner wall of the nozzles is provided with a rotating shaft, the output shaft of the rotating shaft is connected to a rotating motor through a coupling, and the outer wall of the rotating shaft is provided with Rotating roller, the outer wall of the rotating roller is connected with the grinding mechanism box, the inner wall of the nozzle close to the rotating roller is connected with the guide plate, and the outer wall of the bottom end of the nozzle is provided with a nozzle. When the extrusion layer is in contact with the nozzle, the grinding block on the extrusion layer can pulverize smaller agglomerated particles and vibrate a small part of the chemical powder stuck in the pipeline spraying equipment. Shedding, to achieve the effect of self-cleaning.

Description

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

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.
