Description

Mud filter press test device

technical field

The invention relates to a mud filter press experiment device.

Background technique

The traditional mud filter press device is very large, and the cost of the equipment is also high, which is not conducive to teaching experiments, and the operation is relatively cumbersome.

Contents of the invention

The technical problem to be solved by the present invention is to provide a mud filter press experiment device which is compact in structure, low in cost and can demonstrate the mud filter press experiment very conveniently and quickly.

For this reason, the mud filter press experiment device provided by the present invention comprises a filter press cylinder, a filter press cover is configured on the upper end of the filter press cylinder, the filter press cover is connected with a pressurizing device, a piston is arranged in the filter press cylinder, and a press filter The cylinder body and the filter press cover are equipped with a first locking device, the lower end of the filter press cylinder is equipped with a base, the base has a mounting groove, the bottom of the mounting groove has a drainage hole, and a metal filter with a filter hole is installed in the mounting groove Plate, filter cloth is placed on the metal filter plate, the base and the filter press cylinder are equipped with a second locking device, and the base is set on the bracket.

In the present invention, the pressurizing device can apply pressure to the piston through the filter press cover. After the mud in the filter press cylinder is pressurized, the water will pass through the filter cloth and the metal filter plate to collect in the drainage holes on the base, and then be discharged. The operation is extremely convenient, and the structure is compact, which effectively simplifies the filter press structure in the mud filter press device, and does not affect the filter press effect under the premise of simplification, allowing the operator to obtain accurate mud filter press experiment data. And its internal structure adopts a vertical assembly method different from traditional equipment. Its disassembly and installation are more convenient, allowing students to observe the experimental results more intuitively, and the thickness and pressure of the filter press mud can be adjusted accurately, which is very suitable as a teaching experiment. equipment and engineering test equipment.
