Embodiment 1

[0025] figure 1 It is an internal structure diagram of a canal thickener with an inclined plate descending aid structure of the present invention. The connection relationship and working principle of each component are as follows: a canal thickener with a simple structure, including receiving Material pool 2, dense pool 4, buffer pool 9, settling tank 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 part...

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 discloses a ditch-type thickener with an inclined plate sedimentation promoting structure. The ditch-type thickener comprises a thickening pond, a sedimentation pond and a clean water pond which are sequentially and linearly arranged, wherein the three water ponds are arranged under the ground, and the upper parts of the ponds are provided with top covers; the thickening pond is deeper than other ponds, and a discharging hole is formed in the bottom of the thickening pond; the bottom of the sedimentation pond is provided with a mud removing valve, one end of the mud removing valve is communicated with the front end of the bottom of the sedimentation pond, and the other end of the mud removing valve is communicated with the lower part of the thickening pond and is led to the discharging hole; liquid at the upper part of the tail end of the sedimentation pond is led to a drain hole, and feeding holes are formed in the parts, close to the initial end of the thickening pond, of the top covers; and the sedimentation pond is internally provided with the inclined plate sedimentation promoting structure comprising inclined sedimentation plates which are distributed every other a certain distance along the water flow direction, and the inclined sedimentation plates are arranged in a way that the upper parts of the plates are backwards inclined along the water flow direction. By using the ditch-type thickener, tailings are subjected to concentration treatment, and meanwhile, the extruded clear water is discharged or recycled on site; and the thickener is simple in structure and capable of saving space and achieving the aim of saving electricity and water.

Description

technical field [0001] The invention relates to a canal-type thickener with an inclined plate descending-assist structure, which is suitable for processing tailings in a concentrator, and belongs to the field of industrial energy conservation. 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. 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, an...
