Problems solved by technology

[0002] The concentration of tailings in the concentrator is generally not high. If it is discharged directly to the tailings pond, it will consume a lot of power consumption of the mortar pump and the efficiency is low. Therefore, it is necessary to concentrate the tailings
At present, the commonly used concentration treatment equipment is the thickener, but the traditional "round pool" thickener has a large volume, a large area, and high equipment costs, which restrict its application in small and medium-sized mineral processing enterprises. From the perspective of economic rationality, it is generally used less, and basically adopts the direct discharge method, which consumes a lot of electricity and water, and belongs to extensive production.

Embodiment 1

[0025] figure 1 It is an internal structure diagram of a channel-type thickener with a simple structure of the present invention. The connection relationship and working principle between the components are as follows: a channel-type thickener with a simple structure includes receiving tanks 2, Thick pool 4, buffer pool 9, settling pool 12 and clear water pool 14; the depth of the dense pool 4 is greater than the depth of the other four pools, and the bottom of the dense pool 4 is provided with an outlet 8;

[0026] The thickener is a closed structure with a top cover covering each pool, the material receiving pool 2 is located at the head of the thickener, and the feeding port 1 located on the top cover leads to the material receiving pool 2, and the ore pulp passes through The feeding port 1 enters the receiving tank 2, crosses the partition 3, and the heavy particles in the pulp settle in the dense tank 4. The dense pool 4 is divided into left and right parts by the gable ...

example

[0036] Take tailings discharge in iron concentrator as an example: Assume that the amount of tailings discharged in each iron concentrator is G=120m 3 / h, the concentration is 15%. Assuming that the canal width b=1m, the canal water level height h=1m, and the number n=10 of each set of sloping plates, it can be calculated as follows:

[0037] V 2 =G / (3600bh)=120 / (3600×1×1)=0.033333m / s

[0038] t=H / V 1 =(h / n) / V 1 =(1 / 10) / (0.33×10 -4 ) = 3030s

[0039] L=tV 2 =3030×0.033333=101m

[0040] If the HRC type high-pressure thickener is selected, the required area is at least 12m 2 , with a height of about 10m and a huge volume. If the channel-type thickener is used, although the length increases a lot, reaching 101m, but because of the linear arrangement, it will not take up too much space in the factory area, and the structure of the channel-type thickener is simple, there are basically no mechanical moving parts, and the operation and maintenance are very convenient.

Abstract

The invention relates to a channel type thickener with a simple structure. The channel type thickener is characterized by comprising a thickening pool with a channel type structure, a sedimentation tank and a clean water tank which are sequentially arranged in a linear way, wherein the thickening pool, the sedimentation tank and the clean water tank are arranged underground, and a top cover is arranged at the upper parts of the thickening pool, the sedimentation tank and the clean water tank; the depth of the thickening pool is larger than the depths of the sedimentation tank and the clean water tank; the bottom of the thickening pool is provided with a discharge hole; the bottom of the sedimentation tank is provided with a mud cleaning valve; one end of the mud cleaning valve is communicated with the front end of the bottom of the sedimentation tank, and the other end of the mud cleaning valve is communicated with the lower part of the thickening pool and is led to the discharge hole; the liquid at the upper part of the tail end of the sedimentation tank is led to a drainage hole; the top cover is provided with a feeding hole at the position close to the initial end of the thickening pool. According to the channel type thickener, the thickening pool, the sedimentation tank and the clean water tank are sequentially arranged in a linear way; the channel type thickener is arranged underground, has a channel type structure, and is capable of carrying out concentration treatment on tailings and discharging and recycling the separated clear water in situ; the channel type thickener is simple in structure and space-saving, and the aims of saving electricity and water can be realized.

Description

technical field [0001] The invention relates to a channel-type thickener with a simple structure suitable for processing tailings in a mineral processing plant, belonging to the field of industrial energy saving. Background technique [0002] The concentration of tailings in the concentrator is generally not high. If it is discharged directly to the tailings pond, it will consume a lot of power consumption of the mortar pump and the efficiency is low. Therefore, it is necessary to concentrate the tailings. At present, the commonly used concentration treatment equipment is the thickener, but the traditional "round pool" thickener has a large volume, a large area, and high equipment costs, which restrict its application in small and medium-sized mineral processing enterprises.
