Magnesite or magnesium oxysulfate waste recovery system

Abstract

The invention belongs to the technical field of magnesite or magnesium oxysulfate production, and particularly discloses a magnesite or magnesium oxysulfate waste recovery system. Comprising a transfer hoisting device, a storage bin, a weighing bin and a stirrer, the storage bin, the weighing bin and the stirrer are all in an upper feeding and lower discharging mode and are sequentially connected in series through a plurality of sealing auger conveyors, the side wall of a discharging opening of the storage bin is connected with a first air cannon, and the side wall of a discharging opening of the weighing bin is connected with a second air cannon. A weighing module is connected to the position of the side wall, above a discharging port of the weighing bin, of the weighing bin, and a pneumatic butterfly valve is arranged at the discharging port of the weighing bin. The layering phenomenon caused by different specific gravities of materials can be prevented, so that the materials are uniformly dispersed when being used as a filling material in the later period, and the prepared plate product has uniform performance; the method is not only suitable for waste recovery of magnesite or magnesium oxysulfate board products, but also suitable for recovery of other substances with different light and heavy proportions.

Description

technical field [0001] The invention belongs to the technical field of magnesite or magnesium oxysulfide production, and particularly relates to a magnesite or magnesium oxysulfide waste recycling system. Background technique [0002] During the production process of magnesite or magnesium oxysulfide sheet products, the cutting and crushing scraps, surface sanding dust and defective / waste products generated during production contain sawdust, foam particles, glass fiber cloth, no Materials with different weight ratios, such as textiles. In order to reduce the pollution of these crushed materials to the environment, existing enterprises usually recycle these crushed materials as fillers for magnesite or magnesium oxysulfide sheet products, but in the process of recycling, most of them are stored in storage bins. The crushed materials are poured into the storage bin at the entrance of the storage bin. The crushed materials have to go through the falling process from the entran...

Problems solved by technology

In order to reduce the pollution of these crushed materials to the environment, existing enterprises usually recycle these crushed materials as fillers for magnesite or magnesium oxysulfate plate products, but in the process of recycling, most of them are in the storage bin The crushed materials are poured into the storage bin at the entrance of the storage bin. The crushed materials have to go through the falling process from the entrance of the storage bin to the bottom of the storage bin. Because the crushed materials contain substances with different weight ratios, the heavy materials fall first, and the lighter materials fall first. The material falls behind, resulting in stratification, which is not conducive to the uniformity of material dispersion when used as a filler in the later stage, resulting in uneven performance of magnesite or magnesium oxysulfide plate products
