Description

Technical Field

[0001] The present invention relates to the field of hydrometallurgy, and in particular to a carbon powder slurrying device. Background Art

[0002] During the wet zinc smelting process, organic matter in the system will continue to accumulate (brought in by raw and auxiliary materials, equipment lubricating oil leakage or maintenance), which will eventually lead to "plate burning" of organic matter during the electrolytic deposition process, greatly reducing current efficiency, increasing DC power consumption, and increasing production costs. In severe cases, it can cause huge economic losses. In order to open the circuit of organic matter in the wet system, activated carbon powder (hereinafter referred to as carbon powder) is usually added during the solution purification process to adsorb and remove oil. The traditional method of adding carbon powder is to add it directly to the reaction tank or liquid inlet chute. This method of addition makes the carbon powder easily float on the surface of the solution and difficult to mix into the solution, resulting in low adsorption efficiency. In addition, some carbon powder enters the atmosphere through the reaction tank air duct, causing carbon powder loss and environmental pollution. The addition process is serious with dust, and the production site environment is harsh, which is harmful to occupational health.

[0003] This shows that the existing device for mixing carbon powder and solution still needs to be improved. Summary of the Invention

[0004] The present invention aims to at least partially address one of the technical problems in the related art. To this end, one object of the present invention is to provide a carbon powder slurrying device. This device, through an optimized structural design, rapidly mixes carbon powder with a solution, fully agitating and slurrying the mixture without generating dust. It offers advantages such as simple operation, low investment, environmental friendliness, uniform solid-liquid mixing, high carbon powder utilization, low unit consumption, and low production costs.

[0005] In one aspect, the present invention provides a carbon powder slurrying device. According to an embodiment of the present invention, the carbon powder slurrying device includes: a body, wherein a storage space is defined within the body, a conical feed hopper is provided at the upper portion of the body, a liquid inlet structure is provided at the middle portion of the body, a conical lower portion of the body, an air inlet and a pneumatic stirring structure are provided at the bottom of the conical portion, and a liquid outlet pipe is provided at the side portion of the conical portion; wherein the liquid inlet structure includes an external liquid inlet pipe provided at the middle portion of the body and an internal annular liquid inlet pipe provided at the inner wall of the middle portion of the body, and liquid outlets are distributed on the internal annular liquid inlet pipe; the pneumatic stirring structure includes a compressed air pipe and a spherical sieve plate, wherein the compressed air pipe is connected to the air inlet, and the spherical sieve plate is provided at the air inlet.

[0006] According to the carbon powder slurrying device of the embodiment of the present invention, by adopting a conical feed hopper, the carbon powder can naturally slide down into the accommodating space of the device body. The internal annular liquid inlet pipe sprays the solution to evenly wet the falling carbon powder, which can effectively solve the problems of carbon powder suspension, uniform solid-liquid mixing, agglomeration, dust and other problems caused by directly adding carbon powder to the mixing device tank body in the prior art. At the same time, the pneumatic stirring structure at the bottom of the device can use compressed air to pneumatically stir the material, further improving the dispersion effect of the material. By adopting a spherical sieve plate, the problem of uneven mixing that may be caused by the one-way supply of compressed air can be effectively improved. The small sieve holes on the sphere can play a role in uniformly dispersing and guiding the compressed air, creating a uniform and good turbulent state for the material, achieving a good stirring effect, and also preventing a small amount of residual carbon powder from directly entering the compressed air pipe when it is not put into use and causing blockage. Furthermore, the mixed slurry can be discharged from the liquid outlet pipe and sent to the rear operation tank. Therefore, the carbon powder slurrying device of the present invention can quickly mix the carbon powder and the solution, fully stir and slurry them, and will not generate dust through optimized structural design. It has the advantages of simple operation, low investment, environmental friendliness, uniform solid-liquid mixing, high carbon powder utilization, low unit consumption, and low production cost.

[0007] In addition, the carbon powder slurrying device according to the above embodiment of the present invention may also have the following additional technical features:

[0008] In some embodiments of the present invention, the liquid outlet is arranged to be inclined downward, and the angle between the liquid outlet and the horizontal direction is 30 to 45 degrees.

[0009] In some embodiments of the present invention, a check valve is provided on the compressed air pipeline.

[0010] In some embodiments of the present invention, both the external liquid inlet pipe and the liquid outlet pipe are provided with ball valves.

[0011] In some embodiments of the present invention, the carbon powder slurrying device further comprises: a liquid level gauge, and the liquid level gauge is provided on the side outer wall of the body.

[0012] In some embodiments of the present invention, the carbon powder slurrying device further includes: a balancing pipe, which is provided on the liquid outlet pipe and communicated with the accommodating space of the body.
