Abrasive material scraping plate automatic recovery equipment for sandblasting room

Abstract

The invention discloses abrasive material scraping plate automatic recovery equipment for a sandblasting room. The abrasive material scraping plate automatic recovery equipment comprises a fixed rack, sliding racks, roller groups, a cylinder pushing device and reversible sand scraping plates, wherein the sliding racks are installed on the upper part of the fixed rack, the roller groups are respectively installed at the inner side edges of the fixed rack and are in sliding connection with the sliding racks, a plurality of reversible sand scraping plates which are uniformly arranged in parallel are transversely installed between the sliding racks, the cylinder pushing device is installed at the middle part of the upper end of the fixed rack and extends to the sliding racks, and the sliding racks are pushed by the cylinder pushing device to conduct reciprocating motion. Through the way, the abrasive material scraping plate automatic recovery equipment for the sandblasting room provided by the invention is of a mechanical type, so that long-term reliable operation can be ensured, and the sliding racks are pushed by the cylinder pushing device to conduct reciprocating motion, so that energy consumption of the equipment is low, the maintenance cost is low and trenches of the scraping plates are shallow, thereby reducing the civil construction cost.

Description

technical field [0001] The invention relates to the fields of rust removal or polishing of metal surfaces in the field of metal surface treatment, and in particular to an automatic recovery device for abrasive scrapers used in sandblasting rooms. Background technique [0002] At present, there are two types of automatic abrasive recovery inside the sandblasting room on the market: [0003] 1) Using pneumatic lifting (the abrasives sprayed out are sucked back into the shot storage box by the outdoor high pressure through the multi-channel air pipe), the problem of this method is that the energy consumption is high (2-3 times higher than that of the scraper recovery) Power consumption), the suction pipe will be worn out due to high-speed suction and needs to be replaced regularly. A 1-1.5m deep trench is required to set up the equipment; [0004] 2) Set multiple conveyor belts at the bottom of the chamber to return abrasives. This method requires a deep trench, usually 2-2.5...

AI Technical Summary

Problems solved by technology

[0005] The problems of the above two methods: 1) The energy consumption of the equipment is high; 2) The maintenance cost is high; 3) The trench is very deep, so the construction cost of the soil is high
