Quantitative mortar circulation system

Abstract

The invention relates to a quantitative mortar circulation system. The quantitative mortar circulation system is characterized by comprising a mortar stirring bucket (1), a membrane pump (2), a mortar circulation bucket (3) and a mortar tank (4), wherein the mortar circulation bucket (3) comprises a bucket body (3.1), the bottom of the bucket body (3.1) is connected with a discharging pipe (3.7), a guiding tee joint (3.8) and a valve (3.9) are arranged on the discharging pipe (3.7), the guiding tee joint (3.8) is connected with a hose (3.10), the top of the hose (3.10) is connected with a lifting pipe (3.11), the top of the lifting pipe (3.11) is connected with an overflow tee joint (3.12), the position of an overflow port (3.12.2) of the overflow tee joint (3.12) is connected to a material returning cylinder (10) through a material returning hose (9). The quantitative mortar circulation system has the advantages of being high in weighing accuracy and saving raw materials and labors.

Description

technical field [0001] The invention relates to a quantitative turnover system for mortar, which is mainly used for the turnover of mortar used for cutting silicon wafers in the solar photovoltaic module manufacturing process. Background technique [0002] Mortar is one of the main auxiliary materials for cutting silicon rods by silicon wafer cutting machines. According to different cutting processes, the cutting machine needs to be replaced with a certain amount of new mortar and recycled mortar for each cutting. The mortar turnover bucket is used to transfer and quantify the mortar driven into the cutting machine. [0003] The traditional method is that the mortar turnover bucket draws mortar from the mortar mixing bucket through a diaphragm pump, and relies on an electronic scale placed at the bottom of the mortar turnover bucket to determine the amount of mortar drawn out. When the extraction is completed, turn off the diaphragm pump, open the outlet valve of the mortar...

AI Technical Summary

Problems solved by technology

[0004] The traditional method has the following disadvantages: Assuming that the amount of new mortar injected according to the cutting process is 100kg, since the feeding and discharging pipes of the diaphragm pump are relatively thick, if the diaphragm pump is turned off when the electronic scale shows 100kg, then it will be stuck in the inlet of the diaphragm pump. The mortar in the material and discharge pipe is more difficult to handle

However, the feed and discharge pipes of the diaphragm pump need to be cut off or replaced frequently, and it is difficult for even experienced old employees to precisely control the amount of mortar in the feed and discharge pipes

This will not only cause waste of raw materials and increase the workload of employees, but also affect the effective execution of the cutting process

Ultimately, it will have a certain impact on product quality and cost
