Abstract
The utility model discloses a three-foot centrifuge with an automatic braking function. The centrifuge comprises a centrifuge body and a braking device connected with a centrifuge driving motor. The braking device is a set of frequency changers connected with the centrifuge driving motor, and the frequency changers control the driving motor to run. According to the three-foot centrifuge with the automatic braking function, energy is consumed through a braking resistor, and if load inertia is large and stopping time is short, a large amount of reverse electromotive force is generated, and the electromotive force is fed back to the frequency changers; the electromotive force is fed back to modules of the frequency changers, and will cause the damage to the modules of the frequency changers; at the moment, due to a braking unit and the braking resistor, the reverse energy generated when the frequency changers brake in an emergency is consumed, so that the safety of the frequency changers is ensured, the automatic braking function is achieved and can completely replace a traditional manual brake mode, manpower is saved, and the driving motor is protected.
Description
Technical field
The utility model relates to a kind of tripod pendulum type batch centrifugal with automatic brake functions, belongs to chemical mechanical equipment technical field.
Background technology
Tripod pendulum type batch centrifugal, claims again link-suspended basket centrifuge, because bottom support is three suspension columns, in the leg-of-mutton mode of decile, arranges and gains the name.Tripod pendulum type batch centrifugal is a kind of solid-liquid separating equipment, is mainly the solid separation in liquid is removed or the fluid separation applications in solid is gone out.The brake modes of existing tripod pendulum type batch centrifugal is generally manual mode, by pressing the hand brake device being connected with centrifuge drive unit, thereby centrifuge is shut down, while carrying out hand brake, in order to prevent that brake locking from appearring in centrifuge, need to carry out repeatedly incremental brake, cannot once complete, take time and effort, centrifuge brake block is due to repeatedly rubbing action, brake pad can be worn gradually, after using, friction material to change in time centrifuge brake block, otherwise brake ring with at the bottom of rotary drum between will directly contact, thereby lose braking action friction and cause spark, cause security incident.
Utility model content
For the problems referred to above, the utility model provides a kind of tripod pendulum type batch centrifugal with automatic brake functions, and its object is: by VFC motor mode, carry out self-actuating brake, avoid occurring that brake locking phenomenon produces, having saved braking time ，Wei enterprise enhances productivity.
Technical solution of the present utility model:
With the tripod pendulum type batch centrifugal of automatic brake functions, comprise centrifuge, with the brake gear that centrifuge drive motors is connected, it is characterized in that: described brake gear is one group of frequency converter being connected with centrifuge drive motors, by Frequency Converter Control drive motors, is turned round.
Described frequency converter is arranged on drive motors, and connected control panel is fixed at centrifuge side.
Described frequency converter adds braking resistor group by brake unit and becomes, and realizes dynamic braking, starts DC injection braking and realize accurately brake when being about to stop.
The beneficial effects of the utility model:
The utility model carrys out consumed energy by braking resistor; if when load inertia larger; and down time is shorter; will produce a large amount of inverse electromotive forces; these electromotive force can be to frequency converter feedback; feed back in the module of frequency converter; the module damage of frequency converter be can cause, now, brake unit and braking resistor added; the backward energy producing that just frequency converter can be stopped in emergency consumes; thereby the safety that has guaranteed frequency converter, realizes automatic brake functions, can substitute traditional parking brake mode completely; save manpower, protection drive motors.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
The tripod pendulum type batch centrifugal of function of stopping a little of band as shown in Figure 1, comprise centrifuge 1, the brake gear being connected with centrifuge 1 drive motors 2, described brake gear is a frequency converter 3 being connected with centrifuge drive motors, by frequency converter 3, control drive motors 2 runnings, described frequency converter 3 is arranged on drive motors 2, connected control panel 4 is fixed at centrifuge side, described frequency converter 3 adds braking resistor group by brake unit and becomes, realize dynamic braking, when soon stopping, start DC injection braking and realize accurately brake.
To sum up, the utility model accomplishes the end in view.
