Abstract

A mortar distribution system of a multi-line cutting machine comprises a main mortar pipe, a mortar distributing pipe, a plurality of secondary mortar pipes and a plurality of mortar nozzles. The secondary mortar pipes are communicated with the distributing pipe, upper ends of the secondary mortar pipes are communicated with the main mortar pipe, accordingly, mortar outputted to various positions of the distributing pipe by the main mortar pipe via the secondary mortar pipes is basically uniform, and the shortcoming that the quantity mortar in the middle of a distributing pipe is high while quantities of mortar at two ends of the distributing pipe are low is overcome. The mortar nozzles are disposed on the lower side of the distributing pipe, positions and the number of the mortar nozzles are in one-to-one correspondence with those of cutting steel wires, and mortar flowing out from the nozzles is exactly sprayed on the moving steel wires on lower sides of the nozzles. Detachable sealing covers are further arranged at two ends of the distributing pipe, after the mortar distribution system is used, the sealing covers at the two ends of the distributing pipe are opened, residual mortar in the distributing pipe is washed cleanly, and the mortar distribution system can be normally used again. The mortar distribution system has the advantages that flow of the mortar of each nozzle is full and uniform, cutting quality and cutting yield are greatly increased, and consumption of the mortar is reduced exponentially.

Description

The multi-wire cutting machine mortar distribution system

Technical field

The utility model relates to the polysilicon cutting machine of photovoltaic industry, relates to the multi-wire cutting machine mortar distribution system specifically.

Background technology

Fast development along with semicon industry and heliotechnics; Processing request to silicon chip is also improving constantly; The method that generally adopts reciprocating type many steel wires to adhere to the sic slurry in the society is cut into slices through cuing open square stock to silicon ingot again; Factors such as the prescription of sic slurry, flow, density, temperature play crucial effects to cut quality, and stable, uniform sic slurry could satisfy the requirement of chipping qualities and cutting speed.At present, the distribution system of mortar is general to adopt main mortar pipe directly in the middle of the mortar distributing pipe, to insert, and the distributing pipe below is provided with a translot and supplies mortar to be waterfall shape to gush; The mortar flow that is provided with like this in the middle of can obviously seeing is big, and the mortar flow at two ends is few, and the steel wire adhesion mortar amount in the middle of causing is big; Cutting speed is fast; Two ends steel wire cutting speed is slow, has dragged the back leg of monoblock silicon ingot cutting, because " the short slab effect of bucket "; Wait that the slowest root steel wire to switch to the end, cutting just can come to an end.Under the extreme case, even do not drench mortar on the cable wire at two ends, steel wire produces " dry friction " in the silicon ingot joint-cutting, the steel wire fracture of can generating heat.

Also has a problem; During the butt material; Only 1 millimeter of the mobile steel wire diameter of moving of mortar " waterfall " is passed in the interval of steel wire between 150 to 300 millimeters, could drench less than centesimal mortar and participate in cutting on the steel wire; Overwhelming majority mortar is that sky has a walk, and has wasted the configuration and the power of system.Through the repeatedly technological transformation of our company, this problem has obtained satisfactory solution now.

Summary of the invention

The purpose of the utility model is to overcome the defective of above-mentioned prior art, develops a kind of mortar consumption that reduces at double, guarantees to drench saturated, stable, the uniform multi-wire cutting machine mortar distribution system of mortar amount on the every steel wire.

This project is achieved through following technical proposals:

The multi-wire cutting machine mortar distribution system comprises main mortar pipe, mortar distributing pipe, it is characterized in that: also comprise time mortar pipe, mortar nozzle.

Several mortar pipe arrays with distributing pipe and are connected, and the upper end of inferior mortar pipe all is communicated with main mortar pipe, and being provided with like this and making main mortar pipe is average everywhere through inferior mortar pipe to the mortar of distributing pipe output basically, the disadvantage many in the middle of having avoided, that two is few.

The below of distributing pipe is provided with a plurality of mortar nozzles, and its position and quantity are corresponding one by one with incisory steel wire; The cavity shape of nozzle is that to go up circle flat down, and the mortar exit is the flat slot space, and flat seam is vertical setting with the steel wire trend, the mortar that flows out in the nozzle just in time drench below on the mobile steel wire.Guarantee that steel wire has displacement also can drench mortar slightly.

The two ends of distributing pipe also are provided with dismountable seal cover, consider that the sedimentation function of mortar is very strong, after finishing using, should open the seal cover at distributing pipe two ends, all rinse the mortar that the inside is residual well, are convenient to subnormal use down.

The utility model has the advantages that: the mortar flow of each nozzle is full average again, increase substantially cut quality and cutting output, and mortar consumption tenfold ground reduces.

Description of drawings

Fig. 1 is the assembling outline drawing of multi-wire cutting machine mortar distribution system;

Fig. 2 is the STRUCTURE DECOMPOSITION figure of distributing pipe one end;

Fig. 3 is the cutaway view of nozzle.

Description of reference numerals:

1 main mortar pipe, 2 mortar pipes, 3 distributing pipes, 31 seal covers, 4 nozzles, 5 steel wires, 6 silicon ingots.

The specific embodiment

Come further to set forth the utility model below in conjunction with embodiment and accompanying drawing:

Embodiment:, comprise main mortar pipe 1, inferior mortar pipe 2, distributing pipe 3, seal cover 31, nozzle 4 like Fig. 1, multi-wire cutting machine mortar distribution system shown in Figure 2.Move towards to launch to describe from mortar below; Mortar gets into distributing pipe 3 from main mortar pipe 1 through 2 blast slurry pipes 2; The inferior mortar pipe 2 of both sides is 1/4th of distributing pipe 3 length with the spacing of symmetrical centre; Mortar flow at distributing pipe 3 distal-most end nozzles 4 is equal with middle nozzle 4 mortar flows basically like this, has guaranteed the uniformity of each nozzle flow.

When cutting finishes, when needing to suspend a period of time, should pull down the seal cover 31 at distributing pipe 3 two ends, rinse distributing pipe 3 and the residual mortar in nozzle 4 the insides well, in order to avoid the deposition of the solid particle in mortar blocking pipeline is convenient to cutting next time and is carried out smoothly.

Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation; For example be replaced with external screw thread or internal thread to the gas thread that connects nozzle 4; Perhaps change the quantity of inferior mortar pipe into 4 or 6 etc.; Perhaps the short distance translot is set to distributing pipe corresponding position above steel wire to replace nozzle etc., all drops in the protection domain of the utility model requirement.
