Description

Technical Field

[0001] The invention relates to the field of building material equipment, and in particular to a slurry production control system. Background Art

[0002] In the current mortar production operation, independent conveyor lines are mainly used to convey the main material and auxiliary material to the mixing machine for mixing. Since the main material and the auxiliary material only start to contact and mix after entering the mixing machine, there is a lack of pre-mixing treatment. The current process lacks regular sampling of samples during the transportation process, and cannot make real-time feedback adjustments based on the sample indicators. Without pre-mixing of auxiliary materials and main materials, it is difficult for the auxiliary materials to be evenly dispersed in the mixer, resulting in uneven particle distribution of the mortar mixture, which requires longer processing time in the mixer and easily leads to uneven distribution of the mixed mortar. At the same time, due to the lack of a real-time detection feedback system, it is difficult to make real-time adjustments to various materials and moisture content according to sample parameters in the traditional process of mixing, making the moisture content of the mortar after mixing unstable and difficult to control the moisture content during the mixing process. Therefore, in order to solve the above problems, a slurry production control system is needed. Summary of the invention

[0117] Principle of the present invention: a sampling point is set on the detection section 5, and the auxiliary material unloading device is close to the feeding end of the primary transmission device 1. During the material transportation process, since the cross-section of the transmission channel is a U-shaped structure, the conveyor belt vibrates slightly through the movement of the conveyor belt, and the auxiliary material particles can be evenly laid on the surface of the main material. The spray device is close to the discharge end of the primary transmission device 1. During the sand and gravel transmission process, the required water or liquid is added through the spray device as needed, so that the mortar material has a suitable ratio in the pre-mixing mechanism. Next, after the material on the conveyor belt enters the mixing bin 9, the mixing drive assembly 8 drives the active mixing gear shaft 10 to rotate, and the active mixing gear shaft 10 drives the driven mixing gear shaft 11 to rotate through the gear pair 27. The active mixing gear shaft 10 and the driven mixing gear shaft 11 work together to complete the pre-mixing of the main material and the auxiliary material. The sampling points of the pre-detection section 5 at the input end of the sampling conveyor 19 are adjacently arranged. The X-axis sliding assembly and the Y-axis sliding assembly first drive the sampling assembly to the top of the sampling point, and then the Z-axis sliding assembly drives the sampling assembly to move downward, so that the rotating assembly 21 drives the sampling spoon 22 Sampling is performed at the sampling point, and then the X-axis sliding assembly and the Y-axis sliding assembly drive the sampling spoon 22 back to the top of the sampling disk 18, the rotating assembly 21 drives the sampling spoon 22 to pour the sample into the sampling disk 18, and the sampling conveyor 19 conveys the sampling disk 18 to the detection mechanism. The Y-axis sliding assembly drives the sampling assembly close to the cleaning assembly, and the cleaning nozzle 24 cleans the sampling spoon 22 with high-pressure cleaning liquid. After cleaning, the Y-axis sliding assembly drives the sampling assembly close to the drying assembly, and the drying assembly dries the sampling spoon 22 through heat flow to achieve a self-cleaning function to avoid cross-contamination of samples. After the detection mechanism detects the sample, it sends the data to the control module. The signal acquisition end of the control module is used to receive the sample parameters. The control module controls the feeding amount of the auxiliary material feeding device, the transmission speed of the primary transmission device 1, and the spraying amount of the spraying device according to the error of the pre-standard value of the sample data to achieve adaptive production.
