Problems solved by technology

[0003] In the traditional beneficiation process, the water supply and drainage (tailings discharge) are independent, and the equipment of the water supply pump and the slurry pump often do not match, and the efficiency of the water pump is low
In the actual production process, the slurry concentration is often inappropriate, which not only affects the production efficiency and energy efficiency of grinding, but also makes the energy consumption of tailings high.
Although thickening devices (thickeners are generally used) can be used to increase the concentration of tailings to save energy consumption of tailings pumps, but the equipment occupies a large area and requires a large investment, so it is not practical for small and medium-sized mineral processing enterprises.

Embodiment 2

[0030] This embodiment takes the tailings discharge of a small iron concentrator as an example: the tailings flow rate is 120m 3 / h, concentration 15%, density 1100kg / m 3 , the height difference between the tailings pond and the factory area is 45m, and the loss along the way is 15m. The efficiency of the mortar pump is 40%. The power of the matching mill is 240kW.

[0031] The appearance of this embodiment is as figure 2 As shown, the internal structure is as image 3 As shown, it includes a clean water pump area, a slag slurry pump area and a thickening pool area isolated from each other. The thickening pool area includes a thickening pool 13, and a low-concentration tailings pond 14 is formed by a baffle plate and a clean water pump area above. The baffle plate and the slurry pump area form a tailings buffer pool 15, and the tailings buffer pool 15 is above the tailings inlet 3; the slurry pump area includes a slurry pump 6, and the discharge end of the slurry pump 6 ...

Abstract

A complete set of electricity and water-saving water supply and drainage unit suitable for a concentration plant comprises a clean water pump, a slurry pump and a concentration pool, wherein the discharge end of the clean water pump is connected with a clean water outlet leading to a production area, and the suction end thereof is connected with the clean water inlet and the upper part of the concentration pool respectively; the discharge end of the slurry pump is connected with a tailing outlet leading to a tailing pond, and the suction end thereof is connected with the bottom part of the concentration pool; and a tailing inlet leading to the production area is formed above the concentration pool. According to the unit provided by the invention, the tailing is subjected to concentration to obtain the high-concentration tailing through separating out the low concentration tailing, and the high-concentration tailing is discharged to the tailing pond through the slurry pump; and the low concentration tailing with suitable concentration and the clean water are mixed or alternately sent to the process production process for use, so that the electrical energy of the slurry pump can be greatly saved while a large amount of clean water can be saved.

Description

technical field [0001] The invention relates to a power-saving and water-saving complete water supply and drainage unit suitable for mineral processing plants, which belongs to the field of industrial energy conservation. Background technique [0002] At present, there are many mineral processing plants in our country, especially the large number of small and medium-sized mineral processing plants. These mineral processing plants generally belong to the rough production mode, with low production efficiency and large energy consumption. The reason is that the irrationality of the water supply and drainage link is one of the important reasons. [0003] In the traditional beneficiation process, the water supply and drainage (tailings discharge) are independent, and the equipment of the water supply pump and the slurry pump often do not match, and the efficiency of the water pump is low. In the actual production process, the slurry concentration is often inappropriate, which no...
