Embodiment 1

[0038] A kind of quick dehydration system of iron concentrate powder of the present embodiment, as figure 1 As shown, it includes a sedimentation tank 2, a filter device 6, a high-pressure air blowing device 1, an air blowing pipe 3 and a solar heating device 5, wherein: the sedimentation tank 2 includes a pulp inlet 25, a pulp spacer 27, and a sedimentation tank discharge port 28 and the slope bottom 29 of the sedimentation tank; the slurry inlet 25 is opened on the left side of the top of the sedimentation tank 2, and the ore discharge port 28 of the sedimentation tank is opened at the bottom of the right side wall of the sedimentation tank 2; the slurry spacer 27 is arranged in the sedimentation tank The inner side of the ore discharge port 28; the bottom of the sedimentation tank 2 is the slope bottom 29 of the sedimentation tank with a left high and a right low inclination angle, and the inclination slope is 1%; The powder 11 is blown; the solar heating device 5 is arrang...

Embodiment 2

[0041] A kind of rapid dehydration system of iron ore powder of the present embodiment, its basic structure is the same as embodiment 1, and the improvement is: as figure 1 As shown, there are 4 settling tanks 2, which are connected side by side to form an integrated structure; the filter device 6 is a pulp spacer 27 with mesh; figure 2 As shown, the solar heating device 5 includes a heat collecting layer 51, a heat storage layer 52 and a heat conducting rod 53; the heat collecting layer 51 is outside and the heat storing layer 52 is arranged inside, and the fixed connection is an integrated structure; the fixing of the heat conducting rod 53 The end is vertically inserted into the heat storage layer 52 and fixedly connected with the heat collection layer 51, and the free end is vertically inserted into the iron concentrate powder 11 inside the sedimentation tank 2. The heat collection layer 51 is a flat solar heat collector; the heat conduction rod 53 is a telescopic There a...

Embodiment 3

[0045] A fast dehydration system for iron ore powder in this embodiment has the same basic structure as that in Embodiment 2, the difference is that an electric heater is added in the surrounding wall of the pool, and the inner wall of the sedimentation tank 2 is made of metal to increase heat conduction As a result, the outer wall is made of concrete, and the heat loss is slow, avoiding unnecessary waste of heat. The inclination slope of the slope bottom 29 of the sedimentation tank is 3%.

[0046] In the rapid dehydration system of iron ore powder in this embodiment, an electric heater is added to the surrounding wall of the pool. Although the initial investment is increased, the production cost can be effectively reduced, and heating can also be performed without solar energy storage. The specific use It is also possible not to use electric heaters on the two walls of the sedimentation tank to reduce the total loading of the entire system, but the production efficiency will...

Abstract

The invention discloses a fast dehydration system for iron ore concentrate powder, and belongs to the technical field of ore dressing in the metallurgical industry. The dehydration system comprises a sedimentation tank, a filter device, a high-pressure gas blowing device, a gas blowing tube and a solar heating device, wherein the sedimentation tank comprises an ore pulp feeding hole, an ore pulp partition strip plate, an ore discharge hole of the sedimentation tank and a slope bottom of the sedimentation tank; the ore pulp feeding hole is formed in one side at the top end of the sedimentation tank, and the ore discharge hole of the sedimentation tank is formed in the bottom of the side wall at the other side of the sedimentation tank; the ore pulp partition strip plate is arranged at the inner side of the ore discharge hole of the sedimentation tank; the bottom of the sedimentation tank is the slope bottom, with an inclined angle which is higher at the left side and lower at the right side, of the sedimentation tank, and the gradient of the inclined angle is 1-3%; the filter device is arranged at the inner side of the ore pulp partition strip plate; the high-pressure gas blowing device blows gas to the iron ore concentrate powder in the sedimentation tank by virtue of the gas blowing tube; and the solar heating device is arranged on the top of the sedimentation tank. According to the fast dehydration system, the iron ore concentrate powder of ore dressing plants for small and medium-sized iron ore mines is fast in dehydration in the sedimentation tank; the investment is little; and a final product is low in moisture content.

Description

technical field [0001] The invention belongs to the technical field of mineral processing in the metallurgical industry, in particular to a rapid dehydration system for iron ore concentrate powder in metallurgical mine mineral processing plant products. Background technique [0002] Metallurgical industry The iron ore concentrate powder obtained in the production process of the iron ore dressing plant exists in the form of slurry. As the final product for sale, the moisture content should be controlled below 10% to meet product quality and external transportation. Therefore, dehydration treatment must be carried out for iron ore concentrate. The iron concentrate powder dehydration system is an important link in the production process of the concentrator. For large and medium-sized concentrators, a concentrate filtration plant is usually designed, and multiple dehydration equipment such as vacuum filters or filter presses need to be installed inside to solve the problem. Iro...
