Description

Technical Field

[0001] This utility model belongs to the field of metallurgical technology, specifically relating to a nickel smelting slag discharge device. Background Technology

[0002] Nickel smelting is the process of extracting metallic nickel from nickel ore through a series of physical and chemical methods. It is mainly divided into two categories: pyrometallurgical smelting and hydrometallurgical smelting. The specific process depends on the type of ore (sulfide ore or laterite ore). In the process of nickel smelting, slag is an inevitable product of smelting. The smelting furnace discharges the slag into a slag box for cooling, and then discharges it again, which is then transported to a designated location by a conveyor belt.

[0003] Because the waste residue contains a lot of dust, when the waste residue is cooled in the waste residue box and then discharged onto the conveyor belt for transportation, a large amount of dust will be released into the workshop, causing dust pollution and posing a serious hazard to the workers. Utility Model Content

[0004] Based on the problems mentioned in the background technology above, this utility model provides a nickel smelting slag discharge device to solve the problem that a large amount of dust is released into the workshop during the process of slag being cooled in the slag box and then discharged to the conveyor belt for transportation, causing dust pollution to the workshop.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A nickel smelting slag removal device, comprising:

[0007] The cylinder has a top cover and a slag discharge pipe at the bottom, with a control valve on the slag discharge pipe.

[0008] A screw conveyor assembly is disposed on the inner wall of the upper half of the cylinder, and the inlet of the screw conveyor assembly is located outside the cylinder.

[0009] A spiral dust suppression assembly is disposed on the upper inner wall of the cylinder and located above the top of the spiral conveying assembly, with the inlet of the spiral dust suppression assembly located outside the cylinder.

[0010] A dust suppression component is discharged, which is located at the bottom of the slag discharge pipe.

[0011] Based on the above technical solution, the present invention has made the following improvements:

[0012] Furthermore, the spiral conveying assembly includes a spiral guide shell, which is disposed on the inner wall of the upper half of the cylinder. A slag inlet pipe is disposed on the outer peripheral wall of the cylinder at the inlet of the spiral guide shell, and the inner cavity of the slag inlet pipe communicates with the conveying cavity of the spiral guide shell.

[0013] Furthermore, the spiral dust suppression assembly includes a spiral nozzle, which is disposed on the inner wall of the cylinder above the top of the spiral guide shell, and an inlet pipe is disposed on the outer peripheral wall of the cylinder at the top of the spiral nozzle. The inlet pipe communicates with the spiral nozzle, and multiple spray nozzles are arrayed on the pipe wall of the spiral nozzle facing the conveying cavity of the spiral guide shell.

[0014] Furthermore, the dust suppression assembly includes a dust suppression sleeve, which is disposed at the bottom of the slag discharge pipe. The dust suppression sleeve has a liquid collection chamber inside and a water inlet pipe on its outer wall. The liquid collection chamber is connected to the water inlet pipe. Multiple spray nozzles are arranged in an array on the inner wall of the dust suppression sleeve, and each spray nozzle is connected to the liquid collection chamber.

[0015] Furthermore, a dust exhaust pipe is provided in the center of the top of the cylinder cover.

[0016] Furthermore, a support is provided at the bottom of the cylinder.

[0017] The beneficial effects of this utility model are:

[0018] 1. By combining the set spiral conveying component and spiral dust suppression component, the spiral conveying component can transport the waste residue into the lower half of the cylinder in a spiral movement trajectory. During the conveying process, the spiral dust suppression component can spray liquid, so that the liquid is sprinkled on the waste residue transported in a spiral movement trajectory inside the spiral conveying component, thereby cooling and dust suppression of the waste residue inside the cylinder.

[0019] 2. With the dust suppression component installed, as the waste residue is discharged from the cylinder, it passes through the inside of the dust suppression component. At this time, the liquid sprayed by the dust suppression component can wet and suppress the dust in the discharged waste residue, preventing the dust in the waste residue from being dispersed.

[0026] like Figures 1-3 As shown, a nickel smelting slag removal device includes:

[0027] The device includes a cylinder 101, a support 102 at its bottom, a cylinder cover 105 at its top, and a slag discharge pipe 103 at its bottom with a control valve 104. The support 102 supports the entire device, positioning the slag discharge pipe 103 above the conveyor belt. The cylinder cover 105 seals the top of the cylinder 101. The control valve 104 controls the opening and closing of the slag discharge pipe 103, which discharges waste slag from the cylinder 101.

[0028] A screw conveyor assembly is installed on the upper inner wall of the cylinder 101, with its inlet located outside the cylinder 101. The screw conveyor assembly includes a screw guide shell 201, which is located on the upper inner wall of the cylinder 101. A slag inlet pipe 202 is installed on the outer peripheral wall of the cylinder 101 at the inlet of the screw guide shell 201. The inner cavity of the slag inlet pipe 202 communicates with the conveying cavity of the screw guide shell 201. Waste slag can be conveyed into the screw guide shell 201 through the slag inlet pipe 202. In use, by feeding waste slag into the screw guide shell 202, the waste slag moves in a spiral trajectory within the conveying cavity of the screw guide shell 201 towards the lower inner wall of the cylinder 101. The screw guide shell 201 increases the distance the waste slag travels towards the lower inner wall of the cylinder 101.

[0029] A spiral dust suppression assembly is installed on the upper inner wall of the cylinder 101 and located above the top of the spiral conveying assembly. The inlet of the spiral dust suppression assembly is located outside the cylinder 101. The spiral dust suppression assembly includes a spiral nozzle 301, which is installed on the inner wall of the cylinder 101 above the top of the spiral guide shell 201. A liquid inlet pipe 302 is provided on the outer peripheral wall of the cylinder 101 at the top of the spiral nozzle 301. The liquid inlet pipe 302 communicates with the spiral nozzle 301, and liquid can be delivered into the spiral nozzle 301 through the liquid inlet pipe 302. Multiple liquid spraying ports 303 are arrayed on the pipe wall of the spiral nozzle 301 facing the conveying cavity of the spiral guide shell 201, and liquid can be sprayed into the conveying cavity of the spiral guide shell 201 through each liquid spraying port 303.

[0030] As the waste residue is conveyed in a spiral trajectory within the conveying chamber of the spiral guide shell 201 towards the lower half of the cylinder 101, the liquid in the spiral nozzle 301 can be sprayed onto the waste residue being conveyed in a spiral trajectory within the spiral guide shell 201 through each spray port 303, ultimately achieving the cooling and dust suppression of the waste residue falling into the lower half of the cylinder 101; and a dust discharge pipe 106 is provided at the top center of the cylinder cover 105, the top end of which can be connected to an external dust suction pipe, using an external dust suction device to extract most of the dust inside the cylinder 101;

[0031] A dust suppression component is provided at the bottom of the slag discharge pipe 103. The dust suppression component includes a dust suppression sleeve 401, which is located at the bottom of the slag discharge pipe 103. A liquid collection chamber 402 is provided inside the dust suppression sleeve 401, and a water inlet pipe 403 is provided on the outer wall of the dust suppression sleeve 401. The liquid collection chamber 402 is connected to the water inlet pipe 403. The water inlet pipe 403 can deliver liquid into the liquid collection chamber 402. Multiple spray nozzles 404 are arrayed on the inner wall of the dust suppression sleeve 401. Each spray nozzle 404 is connected to the liquid collection chamber 402. Each spray nozzle 404 can spray atomized liquid into the middle of the dust suppression sleeve 401.

[0032] After the waste residue inside the cylinder 101 is cooled down, the control valve 104 is opened to open the slag discharge pipe 103, allowing the waste residue inside the cylinder 101 to fall out of the slag discharge pipe 103 and pass through the dust suppression sleeve 401 onto the conveyor belt. During the process of the waste residue falling out of the slag discharge pipe 103 and passing through the dust suppression sleeve 401 onto the conveyor belt, the liquid in the liquid collection chamber 402 is sprayed out in an atomized form through each spray nozzle 404 to the middle of the dust suppression sleeve 401, thereby wetting and suppressing the dust in the discharged waste residue and preventing the dust in the waste residue from scattering.
