The utility model consists of a cylinder, a principal axis that is connected with the cylinder, an electric motor, a speed reducer that is connected with the electric motor and the principal axis and a bearing seat that supports the principal axis. The cylinder structure is a double layer and a lining is arranged inside the cylinder, while a hollow interlining is arranged between the two layers and a hollow interlining is arranged between the cylinder and an end cover.
Description
Technical field
The utility model relates to the employed ball mill of a kind of ferrite magnetic material industry, especially relates to a kind of internal water cooling ball mill.
Background technology
At present, the employed ball mill great majority of permanent-magnet ferrite magnetic material are roller ball mills, the powder of permanent-magnet ferrite magnetic material need grind to single domain particle, could obtain good magnetic property like this, because the rubbing action of steel ball and barrel, steel ball and material powder produces a large amount of heats, the temperature rising can make the raising of composition and water generation chemical reaction in the raw material of institute's ball milling, generation harmful substance obstruction magnetic property in the mechanical milling process.For example, the permanent-magnet ferrite magnetic material reacts after free SrO, the BaO in the pre-imitation frosted glass meets water in the pre-burning process, generates Sr (OH)
2And Ba (OH)
2When the temperature in the ball grinding cylinder raises, the Sr of generation (OH)
2And Ba (OH)
2Just many more, the slip particle is reunited, toughness increases.Therefore, the Sr of generation (OH)
2And Ba (OH)
2Coercivity H is reduced, and slip particle agglomeration, toughness are big, have influence on crystal grain the degree of orientation, remanent magnetism Br is descended.To have taked the way of trickle in order lowering the temperature, promptly to have added spray pipe, given the cooling of cylindrical shell trickle in the cylindrical shell outside of ball mill.The method of this trickle cooling can only local be cooled off, and cooling effect is poor, and poor working environment does not reach desirable requirement.As a kind of patent No. is the ball mill of CN02127791.5, his structure includes an empty tubular processing cavity, material processed in milling operation flows through processing cavity vertically, processing cavity is around the cylinder axis rotation, in processing cavity, there is the ball that moves freely to affact and makes its pulverizing on the processed material.In processing cavity, its circle tube inner wall is interconnective by many surfaces along axis direction and circumferencial direction, is made up of the metal secter pat amalgamation on the shell that is supported on sealing.On the inner circumferential surface of processing cavity, along the circumferential direction be provided with the operating groove that is rolled into of regulation ball interlock.Gimp and operation energy consumption are reduced like this, and the operation lifetime of the wear-out part of ball mill also is extended in addition.For this purpose, the metal secter pat in the sealing shell is radially to be supported by vibration damping with eliminating the noise.In addition, the ball that regulation is rolled into can be set in processing cavity, and can make the groove that the ball mill axis is the angle of inclination.
Summary of the invention
Problems such as the utility model mainly is poor at the existing in prior technology cooling effect, and the ball milling time is long, and the slip particle size distribution is wide provide a kind of rational in infrastructure, good cooling results, and the ball milling time is short, the rational ball mill of slip particle size distribution.
It is big that the utility model has also solved the prior art environmental pollution simultaneously, and the shortcoming that noise is big has reduced the noise pollution to environment.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the bearing block that mainly comprises cylindrical shell, the decelerator that connects main shaft, motor, connection motor and the main shaft of cylindrical shell, supports main shaft is formed, tube structure is double-deck, the inboard is a lining, there is a hollow interlayer two-layer centre, and a hollow interlayer is arranged in the middle of cylindrical shell and the end cap; The interlayer of the interlayer of cylindrical shell and cylindrical shell and end cap is to cool off for water flowing.
As preferably, the described alignment of shafts is hollow hole body; Hollow hole body plays water flowing, and main shaft plays the effect of ventilating water pipe simultaneously.
As preferably, described main shaft has connecting hole, and connecting hole is connected with the main shaft hollow part, and connecting hole connects the hollow interlayer of cylindrical shell and end cap centre; The water of main shaft is introduced into the interlayer of cylindrical shell and end cap, enters the interlayer of cylindrical shell again.
As preferably, described main shaft one end is communicated with outside water inlet, and the main shaft other end is communicated with outside delivery port, main shaft and the sealing of end cap connection, and main shaft is connected with the interlayer of end cap with cylindrical shell by the through hole of both sides on main shaft; Water enters the main shaft hollow part by water inlet pipe, is entered the interlayer of cylindrical shell again by the interface channel of main shaft hollow part and end cap interlayer.
As preferably, described main shaft is fixed on the bearing, and bearing fixing is on bearing block; Bearing block is laid on the ground.
As preferably, be connected with gear wheel on the main shaft of described cylindrical shell one side; Gear wheel adopts bolt to be connected with main shaft.
As preferably, described input shaft of speed reducer is connected with the line shaft of motor by driving belt, and the output shaft of decelerator is equipped with pinion, the gear wheel engagement on pinion and the cylindrical shell main shaft; Decelerator reduces rotating speed with the bigger moment of torsion of output.
As preferably, described water inlet pipe is connected with the hollow hole body of a side main shaft, and outlet pipe is connected with the hollow hole body of opposite side main shaft; Water enters the hollow hole body of main shaft by water inlet pipe, and the circulation back is flowed out by outlet pipe.
Therefore, the utlity model has rational in infrastructure, make the heat that produces in the abrasive process obtain effective control, reduced the generation of harmful components, improved the degree of orientation of formability, drainage and the magnet of slip, the ball milling time ratio shortened originally, not only saved the consumption of the energy, the distribution of particle sizes scope of slip is narrowed down, improve grinding efficiency, reduced production cost, particularly improved the stability of product and the uniformity of performance, improve production environment simultaneously, reduced noise.
