Description

Technical Field

[0001] The utility model belongs to the technical field of lead-zinc pyrometallurgy equipment, and particularly relates to a cooling cylinder blue powder feeding device. Background Art

[0002] The ISP process is used to smelt lead and zinc. This process involves processes such as blast furnace return smoke sintering, closed blast furnace smelting, slag fuming treatment, crude zinc rectification, crude lead refining, and comprehensive recovery. Its core equipment is a lead-zinc closed blast furnace. The material recovered from the lead-zinc closed blast furnace gas washing system is called blue powder. Blue powder contains a large amount of lead and zinc oxides. If it is discharged randomly, it will pollute the environment and waste lead and zinc resources. Therefore, it needs to be recycled.

[0003] After the blue powder is concentrated and separated by a thickener, it is pumped by a bottom pump to the sintering cooling cylinder for batching. Since the thickening tank is far from the cooling cylinder, and the blue powder has a high solid content and is viscous, it is easy to block the feeding pipeline. Therefore, how to stably, continuously, and evenly add the blue powder to the cooling cylinder has always been an urgent problem for technical personnel in related fields. After retrieval, there is currently no effective means to solve this technical problem. Therefore, the R & D personnel have proposed a cooling cylinder blue powder feeding device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cooling cylinder blue powder feeding device to solve the problem that the blue powder cannot be stably, continuously, and evenly injected from the thickening tank into the cooling cylinder and to avoid blocking the pipeline.

[0005] To solve the above problems, the technical solution of the utility model is as follows:

[0006] A cooling cylinder blue powder feeding device includes a tank body, a conical feeding hopper, and a feeding pipe. The tank body is cylindrical, and its curved top is connected with a feeding pipe and a reflux pipe; the bottom of the tank body is connected with a conical feeding hopper; the lower end of the conical feeding hopper is connected with the feeding pipe. After the blue powder is pumped into the feeding pipe by a bottom pump, the solid material will slide into the feeding pipe along the side wall of the conical feeding hopper under the action of its own weight; an anti-blow valve and a feeding valve are arranged on the feeding pipe. Under normal working conditions, the feeding valve is opened and the anti-blow valve is closed. If the feeding pipeline is blocked, the high-pressure water anti-blow valve can be opened to reverse the pipeline for dredging.

[0007] Furthermore, the feeding pipe is connected with the cooling cylinder, and the blue powder flowing into the feeding pipe finally enters the cooling cylinder through this device to participate in the subsequent recycling batching.

[0008] Furthermore, the tank body is fastened to the bottom steel platform through a tank body fixing plate; the tank body fixing plate and the bottom steel platform are connected by welding.

[0009] Furthermore, a support girder is installed under the bottom steel platform to ensure the stable operation of the device during operation.

[0010] Furthermore, the feed pipe is installed above the reflux pipe, and the installation distance between the feed pipe and the reflux pipe should not be too close.

[0011] Furthermore, the backflush valve is arranged above the feeding valve.

[0012] The beneficial effects of the present utility model are as follows:

[0013] (1) Due to the conical structure at the bottom of the tank body of the present utility model, after the orchid powder is pumped into the tank body, the solid materials will slide into the feeding pipe along the side wall of the conical feeding hopper under the action of their own weight. If the device is working properly at this time, the feeding valve is opened and the backflush valve is closed, then the orchid powder will continuously and evenly enter the cooling cylinder. Since the orchid powder is insoluble in water and has a high viscosity, the solid content of the orchid powder overflowing back to the upper part of the tank body of the thickener is less at this time, and it will not block the reflux pipe at the top of the tank body.

[0014] (2) If the feeding pipe is blocked during the operation of the device, the feeding valve can be closed, and then the high-pressure water backflush valve can be opened to dredge the feeding pipeline. If the water consumption of the cooling cylinder is small and the amount of orchid powder pumped into the tank body is excessive, the materials can flow back to the thickening tank through the reflux pipe at the upper part of the tank body. Since the orchid powder is insoluble in water, almost all the solid materials will precipitate in the conical feeding hopper. At this time, the reflux pipe basically returns clear water and will not easily block the pipeline. After the feeding pipe is dredged by high-pressure water, then the backflush valve is closed and the feeding valve is opened, and the device resumes the normal working state. In this way, it can stably, continuously and evenly add the orchid powder into the cooling cylinder and avoid blocking the pipeline. Description of the Drawings

[0017] The technical solutions in the embodiments of the present utility model will be described below with reference to the drawings in the embodiments of the present utility model.

[0018] As Figure 1As shown in the figure, a cooling cylinder orchid powder feeding device includes a tank body 1, a conical feeding hopper 2, and a feeding pipe 3. The tank body 1 is cylindrical, and its curved top is connected with a feeding pipe 4 and a reflux pipe 5; the bottom of the tank body 1 is connected with the conical feeding hopper 2; the lower end of the conical feeding hopper 2 is connected with the feeding pipe 3; an anti-blow valve 9 and a feeding valve 10 are arranged on the feeding pipe 3. Under normal working conditions, the feeding valve 10 is opened and the anti-blow valve 9 is closed. If the feeding pipe 3 is blocked, the high-pressure water anti-blow valve 9 can be opened to reverse the dredge the pipeline.

[0019] The feeding pipe 3 is connected to the cooling cylinder 11. The orchid powder flowing into the feeding pipe 3 finally enters the cooling cylinder 11 through this device and participates in the subsequent recycling batching. The tank body 1 is fastened to the bottom steel platform 6 through a tank body fixing plate 7; the tank body fixing plate 7 and the bottom steel platform 6 are connected by welding; a support girder 8 is installed under the bottom steel platform 6 to ensure the stable operation of this device during operation; the feeding pipe 4 is installed above the reflux pipe 5, and the installation distance between the feeding pipe 4 and the reflux pipe 5 should not be too close. The anti-blow valve 9 is arranged above the feeding valve 10.

[0020] During the specific operation process: The orchid powder generated by the lead-zinc blast furnace gas washing system is concentrated and separated by a thickener and then pumped into the tank body 1 through the feeding pipe 4 of the present utility model by a bottom flow pump. After the orchid powder is pumped into the tank body 1, the solid material will slide into the feeding pipe 3 along the side wall of the conical feeding hopper 2 under the action of its own weight. At this time, the device works normally, the feeding valve 10 is opened and the anti-blow valve 9 is closed, and the orchid powder will continuously and evenly enter the cooling cylinder 11 and participate in the subsequent recycling batching. Since the orchid powder is insoluble in water and has a high viscosity, the orchid powder overflowing back to the upper part of the tank body 1 of the thickener at this time has a low solid content and will not block the reflux pipe 5 at the top of the tank body 1.

[0021] If the feeding pipe 3 is blocked during the operation of the device, the feeding valve 10 can be closed, and then the high-pressure water anti-blow valve 9 can be opened to dredge the feeding pipe 3. If the water consumption of the cooling cylinder 11 is small and the orchid powder pumped into the tank body 1 is excessive, the material can flow back to the thickening tank through the reflux pipe 5 at the upper part of the tank body 1. Since the orchid powder is insoluble in water, almost all the solid materials precipitate in the conical feeding hopper 2. At this time, the reflux pipe 5 basically returns clear water and will not easily block the pipeline. After the feeding pipe 3 is dredged by high-pressure water, the anti-blow valve 9 is closed again, the feeding valve 10 is opened, and the device returns to the normal working state. In this way, it can stably, continuously and evenly add the orchid powder into the cooling cylinder 11 and avoid blocking the pipeline.
