Abstract
The utility model discloses an air-cooled planetary ball mill. The air-cooled planetary ball mill comprises a rotating disk, a ball milling tank, a ball milling chamber, a tank seat and a ball grinding chamber protective cover, wherein the rotating disk is arranged in the ball milling chamber; the tank seat is mounted on the rotating disk; the ball milling tank is mounted in the tank seat in a detachable way; when the ball mill works, the ball grinding chamber protective cover is closed to seal the ball milling chamber. The air-cooled planetary ball mill is characterized in that a first fan which blows air into the ball milling chamber and a second fan which exhausts air out of the ball milling chamber are arranged side by side on the rear wall of the ball milling chamber; both the first fan and the second fan are controlled by a fan controller; a temperature sensor and a fan control switch are integrated in the fan controller; preferably, the fan is driven by adopting a frequency-variable speed adjustment motor. The air-cooled planetary ball mill is simple in structure and reasonable in layout; the ball milling tank can be cooled automatically, and the work efficiency of the ball mill can be improved effectively, so that the quality of finished products of material powder milling is guaranteed.
Description
Technical field
The utility model relates to a kind of planetary ball mill, relates in particular to a kind of wind cooling temperature lowering planetary ball mill.
Background technology
Planetary ball mill designs for powders such as pulverizing, grinding, dispersed metal, nonmetal, organic, Chinese herbal medicines, being particularly suitable for laboratory research uses, its operation principle is to utilize the rolling at a high speed in grinding pot of abrasive material and test portion, material is produced the strong shear that goes round and begins again, impacts, rolls effect, so that treating material reaches the object of pulverizing, grinding, dispersion, emulsifying material.
Planetary ball mill mainly includes body, main unit transmission device, ball milling chamber, rotating disk, ball grinder, tank seat and power-supply controller of electric; wherein main unit transmission device is arranged in body; main unit transmission device is equipped with motor; motor is connected with rotating disk; tank is sat and is arranged on rotating disk; ball grinder is fixedly mounted on tank and sits the inside; rotating disk is arranged in ball milling chamber; ball milling chamber is provided with over cap; in the time that ball mill is worked; over cap is closed, thereby forms an airtight ball milling chamber, and the power input of planetary ball mill is controlled by power-supply controller of electric.Due to four ball grinders being installed on same rotating disk, in the time of dial rotation, ball grinder in turntable shaft revolution again around Pivot Point Center rotation, make planetary motion.Now, in tank, abrading-ball collision mutually in high-speed motion, grinds and biased sample.
Above-mentioned planetary ball mill in the course of the work, due to the exothermic heat of reaction that the continuous shock between abrading-ball and between abrading-ball and material, material cracking process to be ground are followed, will cause grinding interior temperature rise.Excess Temperature in mill, will reduce grinding efficiency, on the one hand until affect the properties of powder performace of material; On the other hand, also may cause the appearance of the series of problems such as material sex change of non-refractory.In prior art, when people are too high for the temperature rise of the planetary ball mill course of work, often by stopping mill, open ball milling chamber over cap and carry out nature and cool; Treat that temperature drops to a certain degree, then restart ball mill.Like this, on the one hand, owing to stopping mill, uncapping to cool and often carry out according to operating personnel's experience, there is larger blindness, cannot effectively ensure the timeliness of cooling; On the other hand, stop frequently mill, directly affect the continuity of ball mill work.
Utility model content
The purpose of this utility model is, provides a kind of simple in structure, good cooling effect and temperature-fall period to realize the wind cooling temperature lowering planetary ball mill of automation control completely.
The utility model for achieving the above object technical issues that need to address is; how on planetary ball mill, to set up fan rational deployment, according to ball mill internal temperature rise situation timely and effective control fan start-stop or automatically regulate the running power of fan; with ensure ball milling is indoor can be according to the reality of grinding process temperature rise, the technical problem in good time cooling.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is, a kind of wind cooling temperature lowering planetary ball mill, comprise rotating disk, ball grinder, ball milling chamber, fangs and ball milling chamber over cap, its turntable is arranged in ball milling chamber, fangs is arranged on rotating disk, ball grinder is arranged on fangs the inside with removably, in the time that ball mill is worked, ball milling chamber over cap is closed and is formed an airtight ball milling chamber, it is characterized in that, on the rear wall of described ball milling chamber, be also set up in parallel the first fan of the indoor blowing of oriented ball milling and the second fan to the outdoor air draft of ball milling, described the first fan and the second fan are by fan governor control, the inside of described fan governor is integrated with temperature sensor and fan control switch.
The technique effect that technique scheme is directly brought is can detect ball mill internal temperature rise situation in good time, and control timely and effectively fan start-stop according to ball mill internal temperature rise situation, thereby realize the indoor wind cooling temperature lowering that carries out full automation control of ball milling.
Further preferably, said fans is driven by frequency control motor.
The technique effect that this optimal technical scheme is directly brought is, the timely adjustment of the fan running speed of being more convenient for.
For better understanding the utility model, be now briefly described with regard to the wind cooling temperature lowering principle of wind cooling temperature lowering planetary ball mill of the present utility model:
The fan governor arranging on the rear wall of ball milling chamber, the temperature of ball grinder when this controller has temperature sensing device to detect ball milling.When the temperature of ball grinder lower than set safe temperature time, controller does not start fan, allows the air disturbance that ball grinder oneself produces by rotation lower the temperature; When temperature higher than set safe temperature time, controller starts fan, and to force to wind be ball grinder cooling;
Two fans that are set up in parallel on the rear wall of ball milling chamber, in the time that fan does not start, the air disturbance driven rotary that can be produced by ball grinder rotation, plays and leads wind action;
In the time that two fans start simultaneously, one to the indoor air-supply of ball milling, and another is to the outdoor exhausting of ball milling.Like this, indoor by forming a continual and steady cooling blast at airtight ball milling, ball grinder is cooled.
That is, gather the indoor temperature rise data of ball milling by fan governor in good time, and start as required fan to the indoor wind cooling temperature lowering that carries out of ball milling in good time, can realize the automatic cooling of ball grinder.
In sum, wind cooling temperature lowering planetary ball mill of the present utility model has following beneficial effect with respect to prior art:
Simple in structure, rationally distributed, can realize the automatic cooling of ball grinder; Accordingly, can effectively improve the operating efficiency of ball mill, ensure the end product quality of material grinding.
