Problems solved by technology

[0004] 2. The rust removal effect is not ideal
In the traditional method, the explosion-proof surface treated by the treatment liquid is prone to ash hanging, so it needs to be treated again before painting
[0005] 3. Low production efficiency
The traditional method takes about one hour for a set of processes, and the treatment liquid needs to be heated. In order to ensure the treatment effect, the pH value of the treatment liquid is measured regularly, the treatment liquid is replenished into the treatment pool, and the treatment pool is also cleaned regularly. The time cost is high and the labor intensity of the operator is high
[0006] 4. Not conducive to environmental protection
The concentration of sulfuric acid, alkaline water and phosphating solution in the traditional method is high, poisonous and harmful, which will cause some harm to the operator itself, and also pollute the environment, and the discharge of the treatment solution is also a problem

Embodiment 1

[0040] The invention discloses a sand blasting and derusting method for an explosion-proof shell of a mine. The explosion-proof shell adopts a shot blasting machine to throw steel shots, and the shell is subjected to steel shot blasting and derusting treatment. The explosion-proof casing is hooked on the track, and the casing is subjected to steel shot sanding and derusting treatment in the cleaning room. Two shot blasting machines are used to perform steel shot sanding and derusting treatment on the shell at the upper and lower positions respectively.

Embodiment 2

[0042] An explosion-proof casing sand blasting and derusting device for mining, including a shot blasting machine, a track 3 and a cleaning room 9, with a screw conveyor 10, a shot blasting device 11, a shot blasting device 12, a hoist 13, a shot feeding system 14, Electrical box 15, separator 16, hook 17, gate 18, ladder 19, platform 20. Shot blasting machine is housed in cleaning room 9, and track 3 is established on the top of cleaning room 9, and electric hoist 4 hangs hook explosion-proof shell on track 3. The shot blasting machine includes a shot blasting machine, a screw conveyor, an elevator and a separator. The shot blasting machine is equipped with blades and an adjustable orientation sleeve in the center of the blade. The window position of the orientation sleeve forms an angle with the blade. The hook on the track 3 is equipped with a rotary drive mechanism, the drive mechanism includes a motor 7, a reducer 6, a friction wheel 8 and an autorotation wheel 5, the mot...

Abstract

The invention relates to a method and a device for sanding and descaling a mining explosion-proof type shell, belonging to the technical field of sanding cleaning. The method for sanding and descalingthe mining explosion-proof type shell is characterized in that steel shot sanding and descaling is carried out on the explosion-proof type shell by adopting a way of throwing steel shots through a shot-blasting machine. The device for sanding and descaling the mining explosion-proof type shell comprises the shot-blasting machine, a track and a cleaning room, wherein the shot-blasting machine is arranged in the cleaning room; and the track is arranged above the cleaning room and provided with a shell hanger of lifting hanger explosion-proof type. The invention has the advantages of simple technique, small floor area, convenient use, safety and reliability, no discharging of polluted liquid, environmental protection, high production efficiency, low labor intensity, good sanding and descaling effects, and the like.

Description

technical field [0001] The invention belongs to the technical field of blasting and cleaning, and in particular relates to a sand blasting and derusting method and device for an explosion-proof shell used in mines. Background technique [0002] At present, mine explosion-proof electrical appliances are used in underground operations, and their working environment is poor. In order to prevent the surface of explosion-proof electrical appliances from rusting and paint peeling off during use, to ensure the service life of explosion-proof electrical appliances and the safety of coal mines, the electrical appliances During the production process, the shell should be derusted. The traditional rust removal method is the "pickling and phosphating" method, which uses chemical methods to remove rust on the explosion-proof casing. This method has the following problems: [0003] 1. The traditional "pickling and phosphating" method is complicated in process and occupies a large area. ...
