Before the mechanical recovery sandblasting room large parts painting in general use blasting to a surface treatment, in order to obtain a rough flat surface, in order to improve the adhesion of the coating and decorative. Closed blasting system open two. Sand blasting equipment with environmentally friendly design, automatic sandblasting. Shot by sandblasting the recovery can be divided into mechanical recycling stream type and retrievable. Sandblasting room can be called shot, sandblasting room, sandblasting room, sandblasting room, blasting chamber, a sand room. Mechanical recycling sandblasting (pills) room for the whole steel housing body, abrasive use of mechanical recycling. Equipped with ventilation and dust removal system, labor protection devices, lighting devices. Adapted to any abrasive blasting operations. To overcome the traditional sand blasting operations dust, high labor intensity, harsh environment and other issues, it is the ideal place to clean blasting operations. For large parts of the general system of open sand blasting room for product blasting, abrasive ejected automatically recovered by the recovery unit. According to the different ways of recovering abrasive blasting system can be divided into two kinds of mechanical and pneumatic, mechanical abrasive blasting system recovered by the horizontal transport means and lifting means complete, pneumatic abrasive blasting system recovered by pneumatic conveying. 1, the working principle of energy recovery sandblasting room main body of the house, blasting equipment, abrasives recovery, ventilation and dust removal equipment, abrasive sorting device and electronic control device. To simplify the equipment, can be merged abrasive dust collection and ventilation in two parts. Floor fans through the cellular abrasive, dust, air filters concentrate all breathe abrasive. Dust-containing gas through the filter and dust attached to the outer wall of the filter, clean gas is discharged to the plant through the filter portion of the outer part of the cycle to blast the room. Abrasive and heavy abrasive dust continues through the slot into the sorter. Sorter is a pyramid-like structure inside and outside, there is a passage between the inner adjustable cones. By adjusting the core, the air flow passage section may be varied, thereby adjusting the separation ratio. Separation process: When the abrasive and dust through the channel, due to gravity, dust and gases up through the gap between the cone out, but abrasive and coarse cone fell below the shaker. Shaker further abrasive and coarse particle separation, separation of pure abrasive specified through the sieve into the hopper to the blast pot recycled. And then through a filter by sorting the dust and gas, clean gas is discharged outside the plant, dust is then dropped into the waste bucket. 2, sand blasting system structure 2.1 The basic structure of the system according to process requirements, the system selects artificial sand blasting method of different materials with special blasting tank, blasting tank pressure, flow rate can be adjusted at any time according to the requirements of each blast pot with a gun, blasting systems can work simultaneously four guns. 2.2 Housing body Housing body structure sandblasted steel plate welded to the door frame of their skeleton structure, with cross bar connecting between the door frame, door frame with anchor bolts through the mounting block mounted on the ground. Mongolia pressing both sides of the door frame steel sheet thickness of 0.5 ~ 0.8 mm, the surface paint. In order to improve the life of the building body of room inside paste thickness of 6mm wear rubber plate. Technical parameters rubber plate is: hardness 38IRHD, tensile strength 26.6 MPa, elongation of 81%, 83% tear strength, abrasion index (wet) 108, a temperature range of 4-70 ℃. Dust-proof lighting lighting systems require ground lm at indoor illumination of not less than 650 lx. All doors leading to the sandblasting room are equipped with electrical interlock device to ensure when opening any door, blasting the system will stop working. Peripheral door warning lights, lights that being blasted. 2.3 Cellular sandblasting floor room floor dedicated cell floor, the size of each cell floor is 500mm × 500 mm. Sandblasting along the longitudinal direction of honeycomb floor every two rows to form a honeycomb floor module. After falling into the cellular abrasive floor, fans will be attracted to collect it through the hole in the pipe material, then sucked from the collection pipe. 2.4 abrasive abrasive centralized filtration systems share a set of centralized and dust removal system, including centralized fan, central filters. To ensure visibility, ventilation frequency sandblasting room less than 50 times per hour, ventilation and air volume of 65 130 m3 / h. Using three 45 kW wind turbine, wherein each of the two fan flow 21 010 m / h, another amount of wind turbines for the 23 l10 m3 / h. Abrasive concentrator two storeys, the lower abrasive channel Includes air valve and the discharge port. When the airflow with abrasive dust and impurities into the concentrator, because cross-section increases, airflow velocity drop, heavy abrasive and impurities fall through the discharge port abrasive slot. Even the upper concentrator installed 42 filters, lighter gas dust from the fan mounted in the upper part of the concentrator suction filtered through a filter, which 80% of sandblasting room, discharged to the outside plant 20%. Focus filter cartridge using celluloid cartridge, each cartridge filter area of ??28m, a total of 128, evenly along the right side of the sandblasting room. Use of electric automatic pulse cartridge cleaning apparatus, pulse apparatus according to the amount of dust on the filter cartridge adjust the pulse frequency, pulse control switch, filtration efficiency of 99.8%. Ventilation duct has suction pipe, the gas circulation duct, the fresh air intake duct and the outer gas exhaust pipe. Pipe welding of thin steel plate, zinc plated. 2.5 abrasive recycling, abrasive recycling sorting system, sorting system including abrasive tank, sorting, filters and connecting pipes. Abrasive connection from the tank through the tube to the abrasive sorter, where sorting, recycling. In order to improve the life of the sorter, in which the outer and inner surface of the outer cone cone paste wear-resistant rubber. Due to the different product material, blasting abrasive used is also different. To avoid iron abrasive for aluminum car body, under the sorter adds a magnetic device, the separation of iron and non-ferrous abrasive blasting to ensure quality aluminum body. Magnetic separation device is a drum, the drum set under a permanent magnet. The drum rotates, the side due to the magnetic force of the magnet, the iron adsorbed on the abrasive drum; when the drum to the side away from the magnet, the magnetic force disappears, iron abrasive fell within an appropriate container. Drum continues to rotate, iron and non-ferrous abrasive abrasive in the separation. 2.6 Sandblasting equipment sandblasting the entire system configuration 8 blast pot, each blast pot with a diameter of 10 mm gun, two abrasive hopper. 8 blast pot divided into two groups of four, they were placed in their own dedicated abrasive hopper below. Different groups for different abrasive, non-abrasive mix to ensure.
