Abstract

The invention discloses an automatic grout mixing system and the control method thereof. The invention is characterized in that the system comprises a micro processor (1); the micro processor (1) is connected with a man-machine interface (2), a hydro cylinder magnetic valve for dust-discharging valve (5) and a densitometer (4) respectively over a wire. The hydro cylinder magnetic valve for dust-discharging valve (5) is connected with the dust-discharging valve (3). An angular displacement sensor for dust-discharging valve (6) is arranged on the dust-discharging valve (3). The density of the grout can be controlled in the following procedures of collecting data, setting density, normalizing set density and actual density, interrupting the timing, adopting the current valve location of the dust-discharging valve as the antecedent of PID integrate, calculating the PID based on the result of the normalization of the set and actual density; adopting the difference between PID output value and the valve location of the dust-discharging valve as valve location deviation, comparing the valve location deviation with a dead area and the action of flow control over the hydro cylinder magnetic valve of the dust-discharging valve performed by an output switch. Therefore, the density of the grout can be accurately controlled. The automatic grout mixing system is easy to operate and can automatically control the dynamic density.

Description

Technical field: [0001] The invention relates to the technical field of cement slurry mixing, in particular to an automatic cement slurry mixing system and a control method. Background technique: [0002] At present, the cement mixing operation is usually manual operation, the operation is complicated, the labor intensity is high, and it is difficult to accurately control the density. Therefore, the density of the cement slurry fluctuates greatly, which directly affects the quality of the mixing slurry. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a kind of automatic mixing cement slurry system. [0004] Another object of the present invention is to provide a control method for automatically mixing cement slurry. [0005] The invention mainly solves the existing problems of complicated operation of cement mixing, high labor intensity, difficulty in accurately controlling dens...
