AI Technical Summary

Technical Problem

Fine-grained concentrates are difficult to dehydrate effectively during the dewatering process in a filter press, resulting in high moisture content that fails to meet factory requirements and incurring high dewatering costs.

Method used

A cathode group and an anode group are set up in the dewatering tank. The electric field causes negatively charged mineral particles to move towards the anode and positively charged pore water to concentrate towards the cathode, realizing electroosmosis and thus accelerating the precipitation of water.

Benefits of technology

It effectively reduces the moisture content of the concentrate, ensuring that the concentrate moisture content meets the standards and guaranteeing the smooth progress of mineral processing.

Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, specifically to a dewatering tank for fine-grained concentrate. Background Technology

[0002] With the depletion of iron ore resources and advancements in mineral processing technology, fine-grained disseminated iron ore has been developed and utilized on a large scale. In mineral processing, concentrates with high fine-grain content suffer from high surface energy of these minerals, making it difficult to remove moisture from the fine particles using conventional methods during dewatering. Even after filtration, the moisture content remains high, failing to meet factory requirements. While filter press dewatering involves significant investment and high costs, the resulting product often still fails to meet moisture content requirements. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a fine-grained concentrate dewatering tank.

[0004] This utility model is achieved through the following technical solution: A fine-grained concentrate dewatering tank of this utility model includes a concentrate tank composed of a sloping tank bottom and a tank wall. A drainage layer and a filter layer are arranged sequentially from the sloping tank bottom upwards. A drainage trough is arranged at the lowest point of the sloping tank bottom. The feature is that it also includes a cathode group and an anode group. Both the cathode group and the anode group are elongated conductors. The cathode group is arranged in the drainage layer close to the filter layer and is fixedly connected to the tank wall. The anode group is arranged on the upper part of the filter layer and is fixedly connected to the tank wall. The cathode group is connected to the cathode of a DC power supply, and the anode group is connected to the anode of a DC power supply.

[0005] The beneficial effects of this invention are as follows: By adding a cathode group and an anode group to the dewatering tank, the negatively charged mineral particles of the concentrate to be dewatered move towards the anode (i.e., electrophoresis) under the electric field of the cathode group and the anode group, while the positively charged pore water concentrates towards the cathode, resulting in electroosmosis. This accelerates the precipitation of water in the concentrate, effectively reducing the moisture content of the fine-grained concentrate in the concentrate tank, ensuring that the concentrate moisture meets the standards, and guaranteeing the smooth progress of mineral processing. Attached Figure Description

[0006] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0007] The following detailed description of the implementation of this utility model, in conjunction with the accompanying drawings, does not constitute a limitation on this utility model, but is merely an example. Furthermore, the advantages of this utility model will become clearer and easier to understand by explaining them.

[0008] like Figure 1As shown, this utility model discloses a fine-grained concentrate dewatering tank, comprising a concentrate tank 1 consisting of a sloping tank bottom 2 and a tank wall 3. A drainage layer 4 and a filter layer 5 are sequentially arranged from the sloping tank bottom 2 upwards. A drainage trough 7 is provided at the lowest point of the sloping tank bottom 2. The upper part of the filter layer 5 contains the concentrate 6 to be dewatered. The invention is characterized by further including a cathode group 8 and an anode group 9. Both the cathode group 8 and the anode group 9 are elongated conductors. The cathode group 8 is located in the lower part of the filter layer 5 within the drainage layer 4 and is fixedly connected to the tank wall 3. The anode group 9 is located in the upper part of the filter layer 5 and is fixedly connected to the tank wall 3. The cathode group 8 is connected to the cathode of a DC power supply, and the anode group 9 is connected to the anode of a DC power supply.

[0009] Its working principle is as follows: The upper part of the filter layer 5 in the figure is the concentrate 6 that needs to be dehydrated. As can be seen from the figure, the anode group is placed inside the concentrate 6 that needs to be dehydrated. Under the action of the electric field, the negatively charged mineral particles move towards the anode, that is, electrophoresis, while the positively charged pore water concentrates towards the cathode to produce electroosmosis, thereby accelerating the precipitation of water in the concentrate, effectively reducing the moisture content of the fine-grained concentrate in the concentrate pool, ensuring that the concentrate moisture meets the standard, and ensuring the smooth progress of mineral processing.
