Abstract
The utility model discloses a planetary ball mill with a power outage insurance device. The planetary ball mill comprises a ball-milling tank base, a ball-milling tank and a ball mill power control device, wherein the ball-milling tank base is arranged on a turntable; the power outage insurance device is arranged in the power control device, a pressure sensor is arranged on the ball-milling tank base, and the pressure sensor is connected with the power outage insurance device; when the planetary ball mill is used, the ball-milling tank is arranged on the pressure sensor of the ball-milling tank base. When the ball-milling tank has abnormal situations such as loosening, shifting or beating in the process of rotating, the pressure sensor arranged on the ball-milling tank base timely detects the changes in pressure, and transmits pressure change signals to the power outage insurance device, then the pressure change signals are transmitted to the ball mill power control device by the power outage insurance device, and the ball mill power control device timely cuts off a power supply of the ball mill, thereby guaranteeing the application safety of the ball mill.
Description
Technical field
The utility model relates to a kind of planetary ball mill, relates in particular to a kind of planetary ball mill with power-off safety device.
Background technology
In use, ball grinder is fixed on ball milling fangs planetary ball mill.Because ball grinder course of work medium speed is higher, its kinetic energy is larger.In this case, when meeting ball grinder and ball milling fangs junction and occurring damaging and then cause being connected between ball grinder and ball milling fangs to be become flexible, ball grinder will produce violent vibrations, even may depart from ball milling fangs and fly out, and then cause the infringement of the person or property.
Utility model content
The purpose of this utility model is to provide a kind of planetary ball mill with over-voltage automatic power-off protection device, the security of using to improve ball mill.
The technical scheme that the utility model adopted is for achieving the above object, a kind of planetary ball mill with power-off safety device, comprise the ball grinder base, ball grinder, the ball mill power control that are arranged on rotating disk, between described ball grinder and described ball grinder base for removably connecting, it is characterized in that, in described ball mill power control, be provided with power-off safety device, on described ball grinder base, be provided with pressure sensor, described pressure sensing is connected with described power-off safety device; When planetary ball mill is used, described ball grinder is placed on the pressure sensor of described ball grinder base.
The technique effect that technique scheme is directly brought is that this ball mill can detect the appearance of abnormality in ball grinder rotation process in good time, and cuts off in time the power supply of ball mill, thereby guarantees the security of its use procedure.
For understanding better the utility model, existing in conjunction with operation principle, to briefly introduce the utility model be how to realize safety guarantee in its use procedure:
In the specific works process of above-mentioned ball mill, during the abnormal case such as occur loosening, play or beat in ball grinder rotation process, the pressure sensor being arranged on ball grinder base will detect the variation of pressure in time, and this pressure change signal is transferred to power-off safety device, through power-off safety device, be transferred to ball mill power control again, and by ball mill power control, cut off in time the power supply of ball mill.
Accompanying drawing explanation
Fig. 1 is the structural representation of planetary ball mill;
Fig. 2 is the pressure sensor installation site structural representation of planetary ball mill.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is elaborated.
As shown in Figure 1 and Figure 2, planetary ball mill with power-off safety device of the present utility model, comprise the ball grinder base 2, ball grinder, the ball mill power control 5 that are arranged on rotating disk 1, in ball mill power control 5, be provided with power-off safety device 4, on ball grinder base 2, be provided with pressure sensor 3, pressure sensing 3 be connected with power-off safety device 4 (omit in figure, do not draw this connection electric wire); When planetary ball mill is used, ball grinder is placed on the pressure sensor 3 of ball grinder base 2.
Between upper ball grinder and ball grinder base 2, be removably connect (ball grinder not shown in FIG.).
During use, when there is loosening, play or the abnormal case such as beating in ball grinder in rotation process, the pressure sensor 3 being arranged on ball grinder base will detect the variation of pressure in time, and this pressure change signal is transferred to power-off safety device 4, through power-off safety device 4, be transferred to ball mill power control 5 again, and cut off in time the power supply of ball mill by ball mill power control 5, thereby effectively avoid the generation of accident.
