Problems solved by technology

The ultrasonic interface instrument requires a clear interface between the solid and the liquid, which causes the existing detection method to monitor the slime settlement effect in the thickening tank inaccurately and has a large error, which brings many troubles to the actual detection work

Embodiment Construction

[0047] For ease of understanding, combined here Figure 1-8 , the concrete structure and working mode of the present invention are further described as follows:

[0048] Concrete structure of the present invention can refer to Figure 1-8 As shown, it includes a concentration tank 10, and with the concentration tank 10 as the core, a weight detection component 20, a flocculant dosing component 40a and a coagulant dosing component 40b are provided. in:

[0049] Weight detection assembly 20 such as figure 2 and Figure 4 As shown, it includes a coal slime water feed pipe 21, a flexible connecting pipe 25, a sampling pipe 22 and a coal slime water discharge pipe 23 arranged in sequence. In actual assembly, the flexible connecting pipe 25 may be a separate soft pipe structure, such as a corrugated hose. By fixing respectively the coal slime water feed pipe 21 and the sampling pipe 22 at the two ends of the flexible connecting pipe 25, and fixing the coal slime water discharg...

Abstract

The invention belongs to the technical field of slime water treatment, and particularly relates to a slime water concentration system with a concentration detection function and a concentration detection method thereof. The system comprises weight detection assemblies, the weight detection assembly comprises a slime water feeding pipe, a sampling pipe and a slime water discharging pipe which are sequentially arranged along the advancing path of slime water, the slime water feeding pipe is communicated with a concentration tank, and the two ends of the sampling pipe are fixedly connected and communicated with the slime water feeding pipe and the slime water discharging pipe through flexible connecting pipes respectively; the weight detection assembly further comprises a weighing sensor anda drainage valve or a drainage pump; and more than two groups of weight detection assemblies are sequentially arranged along the height direction of the concentration tank. According to the system, the real-time concentrations of slime water at different heights can be obtained by monitoring the real-time weights of slime water samples taken at different heights, the detection process is simple, convenient and rapid, and the detection result is high in reliability, accurate and stable. The invention further provides a concentration detection method so as to further improve the convenience of the detection process.

Description

technical field [0001] The invention belongs to the technical field of coal slime water treatment, and in particular relates to a coal slime water concentration system with a concentration detection function and a concentration detection method thereof. Background technique [0002] Coal is the main energy source in our country, accounting for more than 70% of the primary energy consumption; in a fairly long period of time, the position of coal as the main energy source will not change. Due to the geological structure and mining method, coal is inevitably mixed with a large amount of gangue after mining. This part of gangue has high ash content, high sulfur content, and low calorific value, which has a great adverse effect on the clean utilization of coal. Currently, The main solution is coal sorting. The main separation method of traditional coal is wet separation. The coal preparation method is divided into desliming selection and non-sliming selection according to whethe...
