A production line sand return system

Abstract

The invention discloses a sand sweeping system of a production line. A workpiece sand blasting system comprises a processing circulation line for conveying workpieces; a workpiece feeding region, a sand blasting room, a paint spraying booth, a preheating region, a baking region, a cooling region and a workpiece discharging region are successively arranged on the processing circulation line in the conveying direction; a sand blasting device is arranged in the sand blasting room; the whole processing circulation line has an annular structure; a sand sweeping tank for collecting waste sand is arranged below the sand blasting room; a cyclone separator is connected with the sand sweeping tank through a sand sweeping pipe; the lower part of the cyclone separator is connected with a sand storage box and a pressure tank; the pressure tank is connected to the sand blasting device through a sand pipe; the sand sweeping system of the production line further comprises a sand storage device and an air extracting pump; the sand storage device communicates with the inside of the sand blasting room; the air extracting pump is used for sucking the waste sand and dust in the sand blasting room into the sand storage device; and the sand storage device communicates with an inlet of the cyclone separator through a sand outlet pipeline.

Description

technical field [0001] The invention relates to a sand returning system, which is specifically used for recycling waste sand in the sandblasting process. Background technique [0002] The sandblasting process of the workpiece is a very important process that is gradually popularized in the processing of auto parts, and it is also a process developed under the requirements of high-quality and environmentally friendly processing; the sandblasting process is generally completed by a sandblasting machine, and the waste generated during the sandblasting process The instant recycling of sand can reduce the waste of the sandblasting process, reduce the cost, and improve the environmental protection performance; the traditional sandblasting process is an open structure, and the sandblasting machine is responsible for the realization of the entire sandblasting process, and the improvement of environmental protection ability can only rely on The improvement of the sealing performance ...
