Description

Anti-blocking sand return hopper of sand blasting room

Technical Field

The utility model relates to a sand blasting room sand material retrieves technical field, concretely relates to can prevent sand return fill of recovery system jam.

Background

The sand blasting room is also called a sanding room, a sanding room and a sand blowing room, if a ball-shaped abrasive is selected, the sand blasting room can also be called a shot blasting room, compressed air is used as power, the abrasive (such as steel grit, steel shot, glass shot, quartz sand and the like) forms a supersonic speed jet beam through a special spray gun, the supersonic speed jet beam impacts the surface of a workpiece, and the cleaning of scale removal, burr removal, welding slag, rust removal and the like on the surface of the workpiece is realized, so that the process of coating roughness and the surface strengthening requirement are met. Meanwhile, the sand blasting room system is also provided with a sand material recycling, sorting and dust removing device, so that the sand material recycling and operation environment protection are automatically realized, and the method is the most extensive and universal workpiece surface cleaning mode in international application at present.

The honeycomb type wind power circulation recovery type sand blasting room mainly comprises two parts: one part is a sand blasting system; the other part is a sand material recovery, separation and dust removal system.

The working principle of the sand blasting system of the sand blasting room is as follows: the sand material is stored in the sandblast jar of sandblast host computer, when carrying out the sandblast operation, must the combination valve action on the sandblast jar, will seal sand on the sandblast jar and hold in the palm jack-up, sandblast jar pressurizing. Meanwhile, a sand valve below a sand blasting tank of the sand blasting host is opened, and a boosting valve is opened. Like this, because the sandblast jar is pressurized, the sand outlet is extruded to sand material from the sand inlet of the sand valve of sandblast host computer to the compulsory, through the boosting air current, with the sand material of sand valve sand outlet with higher speed. The accelerated mixed flow of the sand material airflow passes through the sand blasting pipe to the high-speed spray gun, the sand material is further accelerated (the boosting airflow is accelerated to supersonic speed) in the high-speed spray gun, and then the accelerated sand material is sprayed to the surface of the workpiece to be processed at high speed, so that the purposes of surface cleaning and strengthening of sand blasting operation are achieved.

The working principle of the sand material recovery, separation and dust removal system of the sand blasting room is as follows: the air flow outside the sand blasting room enters the sand blasting room through shutters on two sides of the sand blasting room, then enters the sand blasting working room through a uniform flow plate on the top of the sand blasting room, the air flow from top to bottom is formed on the cross section of the sand blasting room, the sand material, the dust, the cleaning material and the like in the sand blasting room enter an abrasive material separating system through a honeycomb type sand suction floor, the abrasive material and the dust material are separated through an abrasive material separator, the useful sand material enters a sand blasting tank to be continuously recycled, the dust and dirt enter a dust removing system along with the air flow, the clean air is discharged into the atmosphere after being filtered by the dust removing system, and the dust and the dirt are stored in a dust barrel to wait for periodic cleaning.

Sand material, dust, clearance etc. inhale the sand floor through the honeycomb and at first fall into back the sand fill, and current honeycomb type wind-force circulation recovery formula sandblast room system returns sand fill and conveying pipeline direct intercommunication, the sandblast in-process, the great waste material of volume (like surplus welding rod etc.) can fall into back in the sand fill, get into conveying pipeline, stifled sand return fill and conveying pipeline, therefore, must carry out the regular clearance maintenance, the parking cost has not only been increased, workman's amount of labour has still been increased, labor efficiency is reduced.
