Abstract
The utility model discloses a ball mill. The ball mill comprises a cylinder, bearings used for bearing the cylinder and maintaining the rotation of the cylinder and a driving device used for driving the cylinder to rotate, wherein the driving device comprises a variable frequency motor, a variator connected with the motor shaft of the variable frequency motor and a belt transmission device connected with the power output shaft of the variator. By the adoption of the variable frequency motor, the rotational speed of the ball mill is changed, so that the grinding speed of the ball mill can be adjusted according to the grinding conditions, and the grinding efficiency is significantly improved; additionally, by the adoption of the driving device arranged on a pedestal at the upper part of the cylinder, the load of the bearings at both ends of the cylinder is reduced due to the tension effect of belts, so that the friction of the bearings and the heat generated by friction of the bearings are reduced, and the energy consumption of the motor is reduced.
Description
Technical field
The utility model relates to a kind of crushing mechanical equipment, particularly a kind of ball mill that adopts wet grinding material to use.
Background technology
Ball mill is to be adapted to a kind of large-size ball mill tool equipment that the industries such as heavy construction pottery, domestic ceramics, sanitary ceramics, electroceramics, metallurgy, chemical industry are used as wet grinding material.Ball mill primary structure is made up of parts such as drive unit, cylindrical shell, electrical controls, has advantages of stable working, safe and reliable, production efficiency is high, output is large, floor space is little, energy consumption is low.Ball mill generally adopted gear ring transmission in the past, because the torsion in transmission process is larger, so gear ring weares and teares comparatively fast, easily scraps; In addition, because ball mill can not be according to torsion self-regulating rotary speed in the past, the operating efficiency of ball mill is reduced, and drive motors easily burn.Existing ball mill adopts belt transmission, bring by many transmissions that are wrapped on cylindrical shell the rotation that drives cylindrical shell, because the purchase cost of driving-belt is lower, change more convenient, replace gradually the ball mill with gear ring transmission so this with bel-drivenn ball mill, but existing ball mill does not still solve the problem of automatic speed regulation, its grinding efficiency is compared ball mill in the past and still could not be significantly improved.
For above-mentioned deficiency, the applicant has designed a kind of ball mill, to address the above problem.
Utility model content
In view of this, the utility model provides a kind of ball mill, this ball mill can be according to the pulverizing situation of material, automatically regulate the rotating speed of cylindrical shell, the efficiency of grinding is improved, and reduced motor energy consumption, extended the service life of motor, thereby solved the problem that existing ball mill grinding efficiency is low and energy consumption of electrical machinery is high.
The utility model addresses the above problem by following technological means:
Ball mill of the present utility model, comprise cylindrical shell, carrying cylindrical shell and maintain the bearing of its rotation and drive the drive unit of cylindrical shell rotation, described drive unit comprises variable-frequency motor, the automatic transmission being connected with the motor shaft of variable-frequency motor and the belt drive unit being connected with the power output shaft of automatic transmission.
Further, described belt drive unit comprises belt pulley and be enclosed within the belt on belt pulley and cylindrical shell, and described belt pulley is coaxially fixedly connected with the power output shaft of automatic transmission.
Further, also comprise the pedestal that drive unit is installed, described pedestal is arranged at the top of cylindrical shell.
Further, described speed changer is automatic transmission.
The beneficial effects of the utility model: ball mill of the present utility model, comprise cylindrical shell, carrying cylindrical shell and maintain the bearing of its rotation and drive the drive unit of cylindrical shell rotation, described drive unit comprises variable-frequency motor, the speed changer being connected with the motor shaft of variable-frequency motor and the belt drive unit being connected with the power output shaft of speed changer.Adopt variable-frequency motor to be changed the rotating speed of ball mill, make ball mill to adjust grinding rate according to grinding situation, grinding efficiency is significantly improved.In addition, adopt drive unit is arranged on the pedestal that is positioned at cylindrical shell top, because the pulling force effect of belt has reduced the load-bearing of cylindrical shell bearings at both ends, the frictional force of bearing and fricative heat are reduced, and then reduced the energy consumption of motor.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the structural representation of ball mill of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is elaborated, as shown in Figure 1: the ball mill of the present embodiment, comprise cylindrical shell 1, carrying cylindrical shell and maintain the bearing 11 of its rotation and drive the drive unit of cylindrical shell rotation, described drive unit comprises variable-frequency motor 2, the speed changer 3 being connected with the motor shaft of variable-frequency motor 2 and the belt drive unit being connected with the power output shaft of speed changer 3.Adopt variable-frequency motor to be changed the rotating speed of ball mill, make ball mill to adjust grinding rate according to grinding situation, grinding efficiency is significantly improved.
As the further improvement of technique scheme, described belt drive unit comprises belt pulley 5 and is enclosed within the belt 4 on belt pulley 5 and cylindrical shell 1, and described belt pulley 5 is coaxially fixedly connected with the power output shaft of speed changer 3.Adopt belt transmission to reduce purchase cost, and make maintain and replace convenient.
As the further improvement of technique scheme, also comprise the pedestal 6 that drive unit is installed, described pedestal 6 is arranged at the top of cylindrical shell 1.Adopt drive unit is arranged on the pedestal that is positioned at cylindrical shell top, because the pulling force effect of belt has reduced the load-bearing of cylindrical shell bearings at both ends, the frictional force of bearing and fricative heat are reduced, and then reduced the energy consumption of motor.
As the further improvement of technique scheme, described speed changer 3 is automatic transmission.When grinding resistance hour, cylindrical shell can increase rotating speed automatically, to improve grinding efficiency.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
