AI Technical Summary

Technical Problem

Traditional sandblasting booths can only use a single type of sand and require multiple sandblasting stations, resulting in high investment costs, high energy costs, and large site area for customers.

Method used

Design a dual-abrasive switching system for a pre-blasting booth in a coating line. By sharing a wide return sand pipe and two sets of symmetrical abrasive processing units with independent switching valves, flexible switching and pollution-free use of two types of abrasives can be achieved. The system includes a sand storage box, a fan, a filter, and a screening device.

Benefits of technology

It effectively reduces equipment investment costs and energy consumption, reduces site occupation, improves sand recycling efficiency and system reliability, and ensures sand quality and ease of maintenance.

Abstract

The utility model relates to a sand blasting room technical field, concretely relates to a kind of coating line front sand blasting room double sand switching system, including back sand pipe, blanking hopper, first switching valve, first sand storage tank, first pipeline, first fan, first pneumatic conveying mechanism, still symmetrically provided with second switching valve, second sand storage tank, second pipeline, second fan, second pneumatic conveying mechanism, the utility model is collected sand by the back sand pipe of common use, blanking hopper, and is provided with two sets of symmetrical sand material processing unit (including sand storage tank, fan, filtration, screening, pneumatic conveying) with independent switching valve in its both ends.By controlling the open-close state of switching valve, sand material in back sand pipe is selectively sucked into corresponding processing unit for recycling, screening, storage and re-supply, so that flexible, pollution-free switching use of two kinds of sand material in single sand blasting station is realized, and by switching back sand system, the type of selected sand material is changed, solving the problem of selecting different sand material for different material workpieces.
