Abstract
The utility model provides a milling tank with the special shape inner cavity structure for swing type ball mills, which comprises a cylinder body and a seal cover, wherein a sealing washer is arranged between the cylinder body and the seal cover which are fixedly connected by bolts; the lower part of the inner wall of the cylinder body is in a cone shape; the seal cover is in an upwards convex circular arc shape. The utility model can decrease the abrasion of the inner wall of the milling tank container, decrease the pollution of crushing material, prolong the service life of the milling tank and enhance the ball milling crushing efficiency of powdered material. After per hundred grams powder lot is milled for four hours, tank wall material of 0.2% mixes in the powder lot.
Description
(1) technical field:
The utility model relates to a kind of mill jar of ball mill, in particular for the mill jar on the four connecting rod pendulum-type ball mills in the laboratory.
(2) background technology:
The pendulum-type ball mill is used for the pulverizing of laboratory to the small quantities of powder material, and the bump that is the mill jar of will material crushed putting into ball mill by the jar abrading-ball reaches the pulverizing purpose.The mill jar of pendulum-type ball mill is a vertical and cylindrical at present, be connected with plate shaped capping with bolted on it, when this kind mill jar carries out ball mill grinding, the inwall of vertical mill jar is subjected to the violent bump of abrading-ball, causes comparatively serious wearing and tearing, and a mill jar inner-wall material is ground down and sneaks in the pulverized dusty material, make by the abrasive dust material and be subjected to severe contamination, find in the test, every hectogram powder is carried out four hours ball millings after, have 0.5% tank wall material to sneak into approximately.
(3) summary of the invention:
The utility model causes by the problem of abrasive dust end severe contamination at prior art, provide a kind of can weaken ball milling the time abrading-ball brinelling of mill jar inwall is alleviated the pendulum-type ball mill mill jar of the special-shaped inner-cavity structure that is polluted by the abrasive dust powder material.
The technical scheme that its technical problem that solves the utility model adopts is:
The pendulum-type ball mill mill jar of abnormity inner-cavity structure comprises and view volume and capping is provided with seal washer between the two, and connects by bolted, and view volume inwall bottom is tapered, and capping is the circular arc that raises up.
Adopt the mill jar of said structure, when abrading-ball clashed into mill jar inwall, becoming positive contact was conical surface contact.Produce bump back abrading-ball and rise along the conical surface that grinds jar inwall, the later stage of rising is subjected to the constraint of cambered surface inwall to be forced to descend, and once more pulverized material is hit pulverizing.With respect to traditional vertical tubular mill jar, force abrading-ball generation rising during owing to abrading-ball in abnormity mill jar and mill jar inwall bump, friction and bump have been weakened with mill jar inwall, reduced the wearing and tearing of mill jar inwall, thereby alleviated because the pollution that mill jar inwall is worn and causes to crushed material.
The utility model can reduce the wearing and tearing of mill can container inwall, reduces the suffered pollution of crushed material, prolongs the service life of mill jar, improves the ball mill grinding efficient to dusty material.After every hectogram powder carried out four hours ball millings, 0.2% the tank wall material of only having an appointment was sneaked into.
(4) description of drawings
Fig. 1 is the structural representation of existing four connecting rod pendulum-type ball mills.
Fig. 2 is the structural representation of the pendulum-type ball mill mill jar of the utility model abnormity inner-cavity structure.
Among the figure: 1, motor, 2, base plate, 3, driving belt, 4, connecting rod, 5, rocking arm, 6, workbench, 7, big belt pulley, 8, tubular mill jar, 9, pressure strip, 10, capping, 11, the view volume of abnormity mill jar, 12, seal washer, 13, the capping of abnormity mill jar, 14, bolt
(5) specific embodiment:
Fig. 1 has provided the structural representation of existing four connecting rod pendulum-type ball mills.Motor 1, big belt pulley 7 etc. are installed on the base plate 2, and the big belt pulley 7 crank effect of having held concurrently is formed four-bar linkage structure with base plate 2, connecting rod 4 and Rocker arm 5, and tubular mill jars 8 is a vertical and cylindrical, is pressed on the workbench 6 with pressure strip 9, and workbench 6 is installed on the connecting rod 4.Motor 1 drives big belt pulley 7 by driving belt 3 and rotates, thereby makes connecting rod 4 swings.After looking pack in the shape mill jar 8 abrading-ball and pulverized material, plate shaped capping 10 is sealed a jar mouth by bolted, under the swing of connecting rod 4, abrading-ball bump crushed material reaches the pulverizing purpose.The inwall of vertical tubular mill jars 8 is subjected to can causing comparatively serious wearing and tearing behind the violent bump of abrading-ball, a mill jar inner-wall material is ground down and is sneaked in the pulverized dusty material, make by the abrasive dust material and be subjected to severe contamination, find in the test, after every hectogram powder carried out four hours ball millings, there is 0.5% tank wall material to sneak into approximately.
In order to overcome above-mentioned tubular mill jar 8 problems that exist, the utility model proposes the pendulum-type ball mill mill jar of special-shaped inner-cavity structure as shown in Figure 2.This abnormity mill jar comprises the view volume 11 and the capping 13 that can be fastenedly connected by bolt 14, and it is conical that view volume 11 inwall bottoms are, and top is cylindrical shape.Capping 13 is the circular arc that raises up.Be provided with seal washer 12 between cylindrical shell 11 and the capping 13, do not overflow with the material in the protection view volume 11.
Abnormity mill jar of the present utility model is installed on the workbench 6 of pendulum-type ball mill.Different in nature mill jar moves along projected path together in company with workbench behind the startup ball mill, and abrading-ball and pulverized dusty material clash in abnormity mill jar mutually, and powder is hit pulverizing.Most of abrading-ball is forced to rise after striking the conical surface of view volume 11 inwalls, returns by the abrasive dust material under the constraint of the arc-shaped inner surface on capping 13 tops, forms abrading-ball the strike once more of powder is pulverized.If adopt the meeting of olive shape abrading-ball effect better, reduced the energy of abrading-ball on the one hand, alleviated further to grinding jar wear extent of interior wall friction, when clashing into mutually between the olive shape abrading-ball in the motion on the other hand, abrading-ball self produces upset and rotates, further crushed material is hit, improved the efficient of ball milling.
The utility model has weakened friction and the bump of abrading-ball with mill jar inwall, the wearing and tearing of mill jar inwall have been reduced, thereby alleviated because mill jar inwall is worn and caused pollution crushed material, every hectogram powder is carried out four hours ball millings after, 0.2% the tank wall material of only having an appointment is sneaked into.The powder that is mainly used in pottery, powder metallurgy industry and the colleges and universities' investigation of materials is pulverized application.
