Description

Technical Field

[0001] The utility model relates to the field of building materials equipment, and particularly relates to a slurry production regulation system. Background Art

[0002] In the current production operation of mortar, independent conveyor lines are mainly used to separately convey the main material and the auxiliary material to a mixing and processing machine for mixing. Since the main material and the auxiliary material start to contact and mix only after entering the mixing and processing machine, there is a lack of pre-mixing treatment. In the current process, there is a lack of regular sampling of samples during the conveying process, and real-time feedback adjustment cannot be carried out according to the indicators of the samples. Without pre-mixing, it is difficult for the auxiliary material to be evenly dispersed in the mixer, resulting in uneven particle distribution of the mortar mixture, requiring longer processing time in the mixer and easily causing uneven distribution of the mixed mortar. At the same time, due to the lack of a real-time detection and feedback system, it is difficult to adjust various materials and moisture content in a timely manner according to the sample parameters during the mixing of the traditional process, resulting in unstable moisture content of the mixed mortar and difficult control of the moisture content during the mixing process. Therefore, in order to solve the above problems, a slurry production regulation system is needed. Content of the Utility Model

[0047] Principle of the utility model: Sampling points are provided on the detection section 5. The auxiliary material feeding device is close to the feeding end of the primary conveying device 1. During the conveying process of the material, since the cross-section of the conveying channel is a U-shaped structure, and the conveyor belt moves with slight vibrations, the auxiliary material particles can be evenly laid on the surface of the main material. The spraying device is close to the discharging end of the primary conveying device 1. During the conveying process of the sand and gravel, the required water or liquid is added through the spraying device as needed, so that a proper ratio is achieved in the pre-mixing mechanism. Then, after the material on the conveyor belt enters the mixing bin 9, the mixing drive assembly 8 drives the active mixing tooth shaft 10 to rotate. The active mixing tooth shaft 10 drives the driven mixing tooth shaft 11 to rotate through the gear pair 27. The active mixing tooth shaft 10 and the driven mixing tooth shaft 11 work together to complete the pre-mixing of the main material and the auxiliary material. The input end of the sampling conveyor 19 is arranged adjacent to the sampling point of the pre-detection section 5. The X-axis sliding assembly and the Y-axis sliding assembly first drive the sampling assembly above the sampling point. Then, the Z-axis sliding assembly drives the sampling assembly to move downward, so that the rotating assembly 21 drives the sampling spoon 22 to take samples at the sampling point. Then, the X-axis sliding assembly and the Y-axis sliding assembly drive it back above the sampling tray 18. The rotating assembly 21 drives the sampling spoon 22 to pour the sample into the sampling tray 18. The sampling conveyor 19 conveys the sampling tray 18 to the detection mechanism. The Y-axis sliding assembly drives the sampling assembly close to the cleaning assembly. The cleaning spray pipe 24 cleans the sampling spoon 22 with high-pressure cleaning liquid. After the cleaning is completed, the Y-axis sliding assembly drives the sampling assembly close to the drying assembly. The drying assembly dries the sampling spoon 22 through the heat flow to realize the self-cleaning function and 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 conveying speed of the primary conveying device 1, and the spraying amount of the spraying device according to the error between the sample data and the standard value to realize adaptive production.
