Abstract
The invention provides a sand pulp cooling device for a silicon chip multi-wire cutting machine, which comprises a sand pulp cylinder, a sand pulp pump, a stirrer and an inlet filter. The sand pulp cooling device is characterized in that a heat exchange pipe is arranged on an inner peripheral wall of the sand pulp cylinder; and a pipe orifice of a sand pulp input tube is positioned between the inner peripheral wall of the sand pulp cylinder and the heat exchange pipe. The sand pulp cooling device has the benefits as follows: firstly, the situation that the device is jammed by sand pulp cannot be caused any more, and the production efficiency is improved; secondly, the device is simplified, and material is saved; and thirdly, the cooling effect is good.
Description
Technical field: the cooling device that the present invention relates to a kind of improvement, the mortar cooling device in a kind of silicon chip multi-wire saw particularly improved.
Technical background: in existing silicon chip multi-wire saw, its mortar cooling device, is shown in accompanying drawing 1, is mainly made up of mortar jar 1, the mortar pump 2 be located in mortar jar 1, agitator 3, inlet filter 4 and mortar heat exchanger 5.The mortar be warmed through workmanship is delivered in mortar jar 1 by inlet filter 4, stirs and be driven into mortar heat exchanger 5 by mortar pump 2 to cool through agitator 3, sends to workmanship again after cooling, so constantly circulation.The deficiency that this kind of cooling device in use exists is: mortar is when by mortar heat exchanger 5, because passage is comparatively narrow, can often block, need stop work mortar heat exchanger 5 disassembly, cleaning, disassembly, cleaning frequently, not only parts easily damage, and large to Influence of production, and production efficiency is greatly reduced.For solving this problem, the applicant has applied for that a name is called the utility application of " mortar cooling device of silicon chip multi-wire saw " September in this year, it can solve the problem preferably, but in use, it still has deficiency, its deficiency is, the mortar of input flows into mortar jar from mortar jar heat-exchange tube inner ring Middle face, because mortar pump is also be positioned at exchanging tube inner ring Middle face, when mortar pump operation, mortar in mortar jar is from periphery to mortar pump setting stream, namely from periphery to central part stream, and form rotating vortex state, when the mortar that need cool flows in mortar jar, by the impact of eddy current, it is just at rotating middle part, have with a certain distance from heat-exchange tube, and be easy to again be drawn up by mortar pump send to workmanship, make mortar cooling effect bad, affect operation.
Summary of the invention: the object of the invention is to, for the deficiency that its mortar cooling device in existing silicon chip multi-wire saw exists, and propose a kind ofly can not to block, produce be well on, the mortar cooling device of the silicon chip multi-wire saw of good cooling results.
The object of the invention can be realized by following technical proposals, a kind of mortar cooling device of silicon chip multi-wire saw, comprise mortar jar, mortar pump, agitator, inlet filter, it is characterized in that, be provided with heat-exchange tube at the internal perisporium of mortar jar, the mortar input pipe mouth of pipe is between mortar jar internal perisporium and heat-exchange tube.
Input distributed uniform in mortar jar for making mortar and in cylinder, run cool time long, the mortar input pipe mouth of pipe is set to vertical channel-shaped, slit opening towards with mortar direction of rotation in cylinder together.
For improving cooling effectiveness and repair and replacement convenience, heat-exchange tube becomes to be fixed on the internal perisporium of mortar jar by support around shape ring-type.
Heat-exchange tube is the copper pipe of diameter 12-16 millimeter.
Effect of the present invention is: the situation that 1, no longer there will be blocking, because be provided with heat-exchange tube in mortar jar, the overheated mortar of workmanship is directly cooled in mortar jar, and be directly driven into workmanship by mortar pump, do not need again through existing mortar heat exchanger, thus avoid the situation occurring mortar blocking device; 2, simplified device, saved material, this is that this device eliminates existing mortar heat exchanger, and heat-exchange tube is directly arranged in mortar jar by it, thus device is more simplified, and production cost is reduced; 3, good cooling results, this mortar input pipe mouth of pipe being mainly reflected in this device is located between mortar jar internal perisporium and heat-exchange tube, and the input pipe mouth of pipe is vertical channel-shaped, its slit opening is towards same with mortar direction of rotation in cylinder, this not only makes mortar flow into distributed uniform in cylinder, nearest from cooling place, and the distance that mortar is run in cylinder the longest (namely can not be drawn up by mortar pump very soon), this also just makes the longest, the good cooling results cool time of mortar.
Below in conjunction with drawings and Examples, the present invention is set forth further:
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of mortar cooling device in existing silicon chip multi-wire saw.
Accompanying drawing 2 is contour structures schematic diagram of the present invention;
Accompanying drawing 3 is plan structure schematic diagram of the present invention;
Accompanying drawing 4 is A-A place sectional view in accompanying drawing 3;
Accompanying drawing 5 is the partial view in accompanying drawing 4.
Detailed description of the invention:
See accompanying drawing 2,3,4,5, a kind of mortar cooling device of silicon chip multi-wire saw, it is made up of mortar jar 1, mortar pump 2, agitator 3, inlet filter 4, heat-exchange tube 5, mortar pump efferent duct 6, mortar input pipe 7, heat-exchange tube support 8.Heat-exchange tube 5 is located on the internal perisporium of mortar jar; Mortar input pipe 7 is connected with inlet filter 4, and its mouth of pipe is between mortar jar 1 internal perisporium and heat-exchange tube 5.Input distributed uniform in mortar jar 1 for making mortar and in cylinder, run cool time long, mortar input pipe 7 mouth of pipe is set to vertical channel-shaped, slit opening towards with mortar direction of rotation in cylinder together.For improving cooling effectiveness and repair and replacement convenience, heat-exchange tube 5 one-tenth is fixed on the internal perisporium of mortar jar 1 by heat-exchange tube support 8 around shape ring-type.For fixation, two holding piece clamping heat-exchange tube 5 places of heat-exchange tube support 8 are concavity, and heat-exchange tube 5 is the copper pipe of diameter 12-16 millimeter.The two-port of heat-exchange tube 5 is respectively cooling water intake and cooling water outlet.
The workflow of this device is: the mortar be warmed through workmanship is passed in mortar jar 1 by inlet filter 4 and mortar input pipe 7, mortar evenly flow into the different depth in mortar jar 1 along the vertical channel-shaped mouth of mortar input pipe 7, because of vertical channel-shaped mouth towards with mortar direction of rotation in cylinder with, the mortar flowed into is namely in rotary moving to central part by the most limit end in cylinder together with making the mortar of vortex in cylinder, mortar inflow place is because of nearest from heat-exchange tube 5, cooled rapidly, and cooled in constantly in rotary moving, when moving to mortar pump 2 place, middle part, drawn up by mortar pump 2 and send to workmanship.
