Mortar stirring and spraying system for squarer

Abstract

The invention belongs to the technical field of squarer and discloses a mortar stirring and spraying system for the squarer. The system comprises a top supporting frame, a liquid supply tank and a mortar stirring tank. A mortar supply pipe is fixedly arranged on the top supporting frame, and lifting power push rods and a telescopic pipe are arranged between the liquid supply tank and the top supporting frame. The mortar stirring tank comprises a tank body, a water supply pipe, a stirrer and a mortar pump, the water supply pipe, the stirrer and the mortar pump are arranged in the tank body, anda mortar outlet of the mortar pump is communicated with the mortar supply pipe. A lower edge plate, air flow pipes and adjustable mortar flow pipes are arranged at the bottom of the liquid supply tank. The system has advantages that a liquid film with a certain pressure can be formed on the surface of a silicon ingot and not only has permeation and dispersion effects but also forms a siphon effect to enable mortar to enter cutting seams under the driving action of a cutting line so as to achieve great cutting effects by interaction with the cutting line. Active mixing is realized through water supplying, self-circulation stirring is realized through a circulating water pump, and mortar stirring efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of square cutting machines, and in particular relates to a mortar stirring and spraying system for square cutting machines. Background technique [0002] The square cutting machine is used for the block cutting of polycrystalline silicon ingots. Due to the unevenness of the upper end surface of the existing silicon ingots after casting, the traditional mortar nozzle cannot make sand adhere to the cutting line when spraying mortar on the cutting line. , resulting in the cut ingots being too large or too small, which cannot meet the production requirements. In addition, there are still some high-pressure nozzles in the prior art that force the mortar to appear uniformly foggy, but when the cutting line cuts into the silicon ingot, it cannot be formed Therefore, the cutting efficiency of the existing cutting wire is low, and the cutting quality is difficult to control. [0003] In addition, because the adequac...

[0002] The square cutting machine is used for the block cutting of polycrystalline silicon ingots. Due to the unevenness of the upper end surface of the existing silicon ingots after casting, the traditional mortar nozzle cannot make sand adhere to the cutting line when spraying mortar on the cutting line. , resulting in the cut ingots being too large or too small, which cannot meet the production requirements. In addition, there are still some high-pressure nozzles in the prior art that force the mortar to appear uniformly foggy, but when the cutting line cuts into the silicon ingot, it cannot be formed To the corresponding effect, therefore, the cutting efficiency of the existing cutting line is low, and the cutting quality is difficult to control

[0003] In addition, since the adequacy of mortar mixing is a necessary condition for determining the quality of mortar, most of the existing mortar mixing uses active stirring first, and then passive stirring in the second cycle, that is, the circulating fluid provides power to achieve a certain degree of stirring, and the stirring is efficient and easy. Deposition occurs, causing the mortar concentration to fail to meet the requirements of the cutting line
