A filter press suitable for laboratory use

Abstract

The invention relates to a filter press, in particular to a filter press for laboratory use, which comprises a transmission part, the transmission part includes a motor reducer, and the output shaft of the motor reducer is provided with a set of friction gears linked with the driving sprocket The output transmission wheel is matched with the friction output transmission wheel, and the transmission part also includes an adjustable elastic warping mounting plate, and a signal feedback device matching the requirements of the electromechanical control system is arranged on the elastic warping installation plate. The present invention overcomes the fact that the filter press for laboratory use in the prior art cannot withstand the torque after the geared motor reducer encounters resistance and increases the current, and at the same time cannot remove the overrun caused by the inertia of the motor, so that the components of the filter press are easily damaged. Therefore, it has the advantages of eliminating the motor overload and motor inertia, and preventing the damage of the motor and the mechanical components of the pulling plate caused by the motor inertia.

Description

technical field [0001] The invention relates to a filter press, in particular to a filter press for laboratory use. Background technique [0002] The drive and control method of the pull plate used in the existing filter press often uses the reducer to drive the chain, and then the manipulator installed on the chain track pulls the filter plate apart. After the signal is sent to the PLC for processing, the signal is processed by the PLC and then fed back to the inverter for detection information, controlling the deceleration motor to stop, and running in the opposite direction to pull the filter plate. The experimental filter press used in testing materials is too small, and the filter plate handle, chain, and manipulator cannot bear the torque after the reduction motor reducer encounters resistance and increases the current, which may easily cause damage to the filter plate, handle, chain, etc. Even pull plate and motor commutation can't be realized at all.

[0004] The purpose of the present invention is to overcome the fact that the filter press for laboratory use in the prior art cannot withstand the torque after the reduction motor reducer encounters resistance and increases the current due to its small size, and at the same time cannot remove the overrunning stroke caused by the inertia of the motor, thereby It is easy to cause damage to the components of the filter press, and it provides a filter press for laboratory use that can eliminate the overload of the motor, and can stop running and pull the plate in the opposite direction after the motor is blocked.
