Description
Technical Field
The utility model relates to a can enough avoid motor stalling to burn out or the fault tripping operation, can avoid pressure filter wiper mechanism to be jack-up again, lead to the unstability, topple, the pressure filter flushing vehicle that has highly stable raising and lowering functions who makes the accident belongs to pressure filter auxiliary assembly and makes the field.
Background
The lifting transmission mode of the filter cloth water washing vehicle of the side beam of the existing filter press is mostly chain transmission, and the driving mode is a direct starting control mode of positive and negative rotation of a motor. The action speed is not adjustable, and the position is controlled by a proximity switch. The lifting process is that a transmission shaft is arranged in the middle, driving chain wheels are arranged at two ends of the transmission shaft and connected with a chain, and the cleaning frame is driven by the chain to lift and descend. Under normal conditions, the cleaning frame rises to a certain height, the proximity switch is triggered, the motor stops rotating, and the rising process is finished. However, if the proximity switch fails, the cleaning rack will rise to the limit position, and the motor will be locked and burned or tripped due to failure.
In the descending process, the motor rotates reversely, the motion is still controlled by the proximity switch to stop, if the proximity switch fails, the cleaning frame descends to the lower limit, and the motor is also blocked, burnt or tripped due to failure. If the cleaning frame pushes up the filter plate in the descending process, the cleaning frame cannot continuously descend, but the chain still rotates at the moment, the cleaning frame continues to operate under the action of the pulling force of the chain on the other side, and due to the action of the counter force, the whole cleaning mechanism is pushed up, so that instability, overturning and accidents are caused.
Disclosure of Invention
The design purpose is as follows: the defects in the background technology are avoided, the motor stalling overheating or burning-out caused by rising to the limit can be avoided, the situation that the cleaning system overturns due to falling and jacking to the filter plate can be avoided, and therefore the safety and the reliability of the operation of the filter cloth water washing mechanism can be effectively improved.
The design scheme is as follows: in order to achieve the above design objectives. The utility model discloses a on current pressure filter chain drive's basis, change the servo motor drive of the control that servo driver was changed into to the positive reverse motor of former direct start, servo driver's action is then by PLC control system automatic control. The purpose is as follows: firstly, the action moment is adjustable, no matter in ascending or descending mode, the moment is adjustable, can reduce. Even if the washing rack ascends to the limit position, the moment is still small, the servo driver alarms and stops, the transmission mechanism is not damaged enough, and the flushing system cannot overturn when the washing rack descends to the filter plate due to the small moment; and secondly, the control stability is improved. Through the setting of parameters, the movement mode of the cleaning frame is in a position mode, the movement speed and the torque of the cleaning frame are adjustable, the speed is uniformly increased when the cleaning frame is started, the speed is uniformly decreased when the cleaning frame is stopped, and the system is not impacted when the cleaning frame is started and stopped; and thirdly, in the process of movement, because the moment mode and the position mode are switched, the 'clicking' sound of the brake can not be generated when the movement is stopped, and the noise generated in the process of operation is very weak, thereby being beneficial to reducing the noise pollution.
The technical scheme is as follows: a side beam of a box type filter press is provided with a lifting control washing vehicle driven by a filter cloth washing vehicle chain, a roller at the lower end of a cleaning frame in the lifting control washing vehicle is matched with a guide rail, the roller is driven to travel by a transverse chain wheel chain transmission mechanism at the lower end of the cleaning frame, the upper part of the cleaning frame is provided with a transmission shaft, the transmission shaft is driven by a servo motor controlled by a servo controller, and the transmission shaft controls the lifting or the lowering of the cleaning frame through a longitudinal chain wheel chain transmission mechanism to complete the cleaning of each filter plate.
Compared with the prior art, the utility model, firstly adopt the pressure filter washing car that the servo drive structure designed, because servo driver and brake resistance install in the electrical control box, electrical control box installation fan ventilates and dispels the heat, and the electrical control box is installed in cleaning system's top or side-mounting. The cleaning device has the advantages that the cleaning device is connected with the aviation plug and the servo motor through the cable, so that the phenomenon that the motor is locked and rotated too hot or burnt down due to the fact that the motor is raised to the limit in the background technology can be avoided, the phenomenon that the cleaning system overturns due to the fact that the cleaning system is jacked to the filter plate in a descending mode can be avoided, and the safety and the reliability of operation of the filter cloth water.

Detailed Description
Example 1: reference is made to figures 1-3 of the drawings. A side beam of a box type filter press is provided with a lifting control washing vehicle driven by a filter cloth washing vehicle chain, a roller at the lower end of a cleaning frame 2 in the lifting control washing vehicle is matched with a guide rail, the roller is driven to travel by a transverse chain wheel chain transmission machine 1 positioned at the lower end of the cleaning frame 2, a transmission shaft 4 is arranged at the upper part of the cleaning frame 2, the transmission shaft 4 is driven by a servo motor 5 controlled by a servo controller, and the transmission shaft 4 controls the lifting or descending of a cleaning frame 3 through a longitudinal chain wheel chain transmission mechanism 6 to complete the cleaning of each filter plate.
When the cleaning is not started, the cleaning frame is at the position 0, the ascending stop limit proximity switch is switched on at the moment, and the motor is in a brake state.
After the cleaning is started, the cleaning frame moves from the position 0 to the position 1, the working section is in a torque mode, when the working section moves to the position 1, the valve controls the proximity switch to be triggered and switched on, and the cleaning frame pauses. And servo switching is carried out to a position mode, the cleaning valve moves from a position 1 to a position 2 after the switching time of the cleaning valve is up, the moving process is in the position mode, and the height adjusting parameter of the position 1 is set on a servo driver parameter control panel. If the cleaning mechanism is pushed against the filter plate, the cleaning mechanism cannot be pushed up due to the fact that the descending torque is set to be small. After reaching position 2, the wash rack decelerates and pauses for a settable time. After the pause time, the wash rack is raised and moved from position 2 to position 1, the process being in position mode. After the position 1 is reached, the servo detection reaches the position 1, the cleaning frame decelerates and pauses, and the cleaning valve is waited to be switched. After the switching time has elapsed, the cleaning moves from position 1 to position 0, the process being in torque mode. In the process, if the proximity switch fails, the transmission mechanism cannot be damaged due to the fact that the set torque is small after the cleaning frame reaches the upper limit.
It is to be understood that: although the above embodiments have described the design idea of the present invention in more detail, these descriptions are only simple descriptions of the design idea of the present invention, and are not limitations of the design idea of the present invention, and any combination, addition, or modification without departing from the design idea of the present invention falls within the scope of the present invention.
