Description

Technical Field

[0001] This utility model relates to the field of wet ball mill gangue pulping technology, specifically to a wet ball mill gangue pulping system with automatically controllable concentration. Background Technology

[0002] Gangue pulping is a process of mixing gangue powder with water to generate a slurry. Currently, the main form of gangue pulping involves crushing gangue to a size of less than 3mm, mixing the gangue powder with water, and then obtaining a gangue slurry. However, research has shown that wet ball milling produces a slurry with better fluidity and transportability. Ball milling refers to the process where small-diameter gangue material and water are mixed inside the ball mill barrel and transformed into a standard slurry through the impact, compression, and grinding action of steel balls. Currently, the control method for gangue pulping in ball mills is generally manual, lacking sufficient intelligent support. This leads to untimely updates of system parameters during operation, and the inability to quickly adjust the gangue feed rate and water supply to adapt to changes in slurry concentration, thus affecting the quality of the produced slurry. Slurry with substandard concentration and quality is prone to segregation in the conveying pipeline, and may even cause pipeline blockage. Utility Model Content

[0003] The purpose of this invention is to provide a wet ball mill gangue slurry preparation system with automatically controllable concentration, solving the problem of automatically adjusting the slurry concentration in the ball mill and ensuring that the concentration is maintained within a suitable filling range.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatically controllable wet ball mill gangue slurry preparation system includes a water source, a gangue powder source, a frequency converter belt conveyor, a weighing feeder, a center-driven wet ball mill, and a PLC controller. The water source is connected to the center-driven wet ball mill via a pipeline, on which an electromagnetic flow meter and a flow regulating valve are installed. The gangue powder source is conveyed to the center-driven wet ball mill via the frequency converter belt conveyor and the weighing feeder. The frequency converter belt conveyor, the weighing feeder, the electromagnetic flow meter, and the flow regulating valve are connected to the PLC controller. A pressure sensor is installed on the weighing feeder and is connected to the PLC controller.

[0005] Furthermore, the weighing feeder is connected to the center-driven wet ball mill via a steel chute.

[0006] Furthermore, in the centrally driven wet ball mill, the slurry is connected to a slurry delivery pipeline via a grouting pump. A mining concentration meter is installed on the slurry delivery pipeline, and the mining concentration meter is connected to a PLC controller.

[0007] Furthermore, the PLC controller is connected to a host computer for remote monitoring.

[0008] The beneficial effects of this utility model are as follows: This utility model provides a wet ball mill gangue pulping system with automatically controllable concentration, achieving fully automated, unattended production of the pulping process, significantly reducing labor costs and operational risks. PLC control improves production efficiency, and various parameters are precisely controlled, ensuring the consistency and reliability of product quality. Simultaneously, it can record and analyze data during the production process in real time, supporting continuous improvement of the production process and making it more efficient and environmentally friendly.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] Example: An automatically controlled wet ball mill gangue slurry preparation system includes a water source 1, a gangue powder source 2, an electromagnetic flowmeter 7, a flow regulating valve 8, a weighing feeder 4, a variable frequency belt conveyor 3, a center-driven wet ball mill 5, a mining concentration meter 10, and a PLC controller 6. This system employs a slurry preparation method combining quantitative water supply and variable feed. When the slurry concentration exceeds the set range, the feeding system will correspondingly reduce or increase the feed rate to ensure stable slurry concentration. The automatically controlled wet ball mill gangue slurry preparation system consists of a water supply system, a feed system, and a concentration feedback system.

[0013] The water supply system includes a water tank, an electromagnetic flow meter 7, and a flow regulating valve 8. The water source 1 in the water tank is transported to the centrally driven wet ball mill 5 through stainless steel pipes.

[0014] The feeding system includes a variable frequency belt conveyor 3 and a weighing feeder 4 equipped with a pressure sensor 9. The pressure sensor 9 on the weighing feeder 4 is responsible for detecting the weight of the gangue powder and transmitting the data to the PLC controller 6 through the PLC input port. The controller analyzes the received data and adjusts the operating frequency of the variable frequency belt conveyor 3 accordingly, thereby controlling the speed of the conveyor belt to achieve precise increase or decrease of the gangue feed rate.

[0015] The concentration feedback system includes a mine-use concentration meter 10 installed on the slurry pipeline. The measured value is transmitted to the PLC controller 6 via the PLC signal input terminal. The PLC controller 6 is responsible for analyzing the difference between the measured value and the preset concentration value, and adjusting the belt speed of the variable frequency belt conveyor 3 through the PLC output terminal to adjust the slurry concentration and ensure that it is maintained within a suitable range.

[0016] The PLC controller 6 for adjusting slurry concentration is remotely installed in the central control room, allowing operators to centrally manage and control the system concentration. This controller integrates highly intelligent and automated functions, enabling real-time monitoring and adjustment of slurry concentration to ensure the stability and accuracy of the production process.

[0017] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. All equivalent structural changes made based on the description and drawings of the present utility model should be included within the scope of protection of this patent.
