The axle center of the rotation axle is provided with an axle hole, and the predefined position of the cutter seat body is provided with a plurality of through holes all communicated with the axle hole. One end of the rotation axle is pivoted with a joint capable of 360 DEG rotation, and the joint is communicated with the axle hole and externally connected with a water source, so that the cooling water can be lead in the axle hole and ejected out of the through holes via the cutter seats.

Description

Water cooling structure of disintegrator

The utility model relates to the water-cooling structure of pulverizer.

According to prior art as can be known, can influence the running smoothness because of friction generates heat during pulverizer uses, common settling mode is to pass through from the charging aperture top of pulverizer with a water pipe, directly is fed into facility inside with water, carries out water-cooled.This kind type of cooling of pouring water and since from the top drip the water that gets off must not be bound to drop onto pulverizer rotating shaft and on tool rest and cutting knife, so cooling effect and inhomogeneous as if reaching preferable cooling effect, then need pour into a large amount of cooling waters.

The utility model is intended to solve this defective, be that main purpose of the present utility model is the water-cooling structure that is to provide a kind of pulverizer, it has uniform cooling effect, and its cooling water all can fill a part utilization, can not cause waste, and can carry out the cleaning at initial stage to comminuting matter by cooling water.

Water-cooling structure according to a kind of pulverizer provided by the utility model includes: a support body, and its inside has a spatial accommodation; One rotating shaft, it is hubbed on this support body and is contained in this spatial accommodation, is subjected to the external force transmission; A plurality of tool rests are to be installed in this rotating shaft along this rotating shaft axially spaced-apart; With the corresponding interior cutter of tool rest number, be to be installed on these tool rests, with this rotating shaft rotation; With the corresponding outer cutter of interior cutter number, be to be installed in this support body spatial accommodation inwall, and rotate interior cutter meet, in order to comminuting matter with these; It is characterized in that: the axle center of this rotating shaft is provided with an axis hole, the body body precalculated position of these tool rests is provided with the through hole of predetermined number, these through holes all with this axis hole conducting, being pivoted at an end of this rotating shaft one can the rotating joint of 360 degree, this joint also is communicated with axis hole, the external water source of this joint is in order to the through hole ejection via tool rest of the axis hole that cooling water imported rotating shaft.

By above-mentioned structure, water can be via axis hole directly to whole rotating shaft cooling, and it directly cools off tool rest via through hole, and the water jet via through hole sprays towards knife edge the place ahead of cutting knife again, directly cools off with the knife edge to cutting knife.

In addition, this joint can an external high-pressure water, when water under high pressure sprays via axis hole and through hole, be subjected to the centrifugal action of rotating shaft rotation and produce acceleration, make water under high pressure reach the impulse force ejection at faster speed, when being sprayed onto comminuting matter strong flushing is carried out on its surface, make the dirt that adheres on it be able to initial gross separation, be beneficial to follow-up washing and cleaning operation.

Now be illustrated in the back for an embodiment and conjunction with figs.:

Fig. 1 is the front elevational schematic of the utility model one embodiment;

Fig. 2 is the schematic side view of the utility model one embodiment.

See also each accompanying drawing, the water-cooling structure of the utility model pulverizer includes:

One support body 10, its inside have a spatial accommodation 11, and a feeding mouth 12 is established in its top, and a discharging opening 13 is established in the below, and discharging opening 13 is provided with a filter screen 14;

One rotating shaft 20 is hubbed on this support body 10 and is contained in this spatial accommodation 11, its central authorities along major axis to being provided with an axis hole 21, the end sealing of this axis hole 21;

A plurality of tool rests 30 are to be installed in this rotating shaft 20 along these rotating shaft 20 axially spaced-aparts, and its body body is along the through hole that radially is provided with predetermined number 31 of rotating shaft 20, this through hole 31 and with these axis hole 21 conductings;

With the corresponding interior cutter 40 of tool rest number, be to be installed on these tool rests 30, to rotate with this rotating shaft 20, the aperture of these through holes 31 is cutter 40 knife edge the place aheads in this then;

With the corresponding outer cutter 50 of interior cutter number, be installed in this support body 10 precalculated positions, with cutter 40 meets in these rotations, in order to comminuting matter;

One joint 60, can 360 degree rotate freely, be installed in the openend of these rotating shaft 20 axis holes 21, and with axis hole 21 conductings;

One pump 70, it is communicated with this joint 60 with a water pipe 71, in order to high-pressure water to be provided;

One motor 80 rotates in order to drive this rotating shaft 20.

Combination by above-mentioned member, the utility model in use, comminuting matter is dropped into by support body 10 top feeding mouths 12, in the warp,

outer cutter

40,50 meets and be ground into fine particle gradually, filter screen 14 via discharging opening 13 sifts out, when material when spatial accommodation 11 is cut repeatedly, water by pump 70 with high pressure through water pipe 71, joint 60 and entering in rotating shaft 20 axle center 21, elder generation's countershaft 20 directly cools off, flow to the through hole 31 of tool rest 30 again by axis hole 21, spray toward interior cutter 40 knife edge the place aheads with powerful speed by through hole 31 apertures again, the tiny current impact comminution material surface of ejection is washed it tentatively substantially, make the dirt that adheres on it earlier separated, during cutter 40 the place aheads, interior cutter 40 rotations just in time touched with it in cooling water was sprayed onto, directly internally cutter 40 knifes edge cooling, and, and 360 degree rotations are done in support body 10 inside spray along with rotating shaft 20 rotations and quicken by the current of tool rest 30 through holes 31 ejection, can be to support body 10 inner and outer cutter 50 carry out uniform water cooling.In other words, this kind of the utility model cooling structure, not only but countershaft 20, tool rest 30 and interior cutter 40 directly cool off, Pen Chu water still can cool off support body 10 inwalls and outer cutter 50 simultaneously, comminuting matter can be cleaned again, not only have evenly direct efficient cooling, the enhancement effect of in advance cleaning dirt is more arranged simultaneously.Than common mode of only down pouring into by the top with water, its cooling directly rapidly evenly and tool clean and crush the enhancement effect of material.
