Description

Technical Field

[0001] This utility model belongs to the field of slag discharge technology in metal smelting, specifically a bottom-discharge smelting device for aluminothermic reduction of crude lead. Background Technology

[0002] In metal smelting, crude lead can be produced through aluminothermic reduction, with the reduction vessel being a commonly used piece of equipment for crude lead reduction. After the reduction reaction is complete, a large amount of reducing slag is generated, which requires a dedicated slag discharge pipe for removal.

[0003] During slag discharge from the existing crude lead reduction vessel, the applicant discovered that:

[0005] 2. When discharging material through the slag discharge pipe, a lot of dust will appear in the slag, causing serious dust pollution and easily affecting the health of workers.

[0006] To address the aforementioned problems, an aluminothermic reduction crude lead bottom-slag smelting apparatus is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following will combine Figures 1-4 A detailed description is provided of an aluminothermic reduction crude lead bottom-slag smelting apparatus according to an embodiment of this utility model.

[0025] Example:

[0026] This utility model provides an aluminothermic reduction crude lead bottom-slag smelting apparatus, for reference. Figures 1 to 4 As shown, the device includes a reduction tank 1 for the thermal reduction of crude lead and aluminum and a vacuum cleaner 2. The bottom of the reduction tank 1 is fixedly connected to and connected to a slag discharge pipe 3. Multiple hydraulic rods 4 are fixedly installed on the left and right side walls of the slag discharge pipe 3. A crushing cone 5 is fixedly installed at the piston end of each hydraulic rod 4. When the slag discharge pipe 3 is blocked during slag discharge, the personnel can activate the hydraulic rods 4 to drive the crushing cone 5 into the slag discharge pipe 3. Then, the crushing cone 5 can be used to crush the accumulated slag, thereby facilitating the normal discharge of slag from the slag discharge pipe 3 and avoiding blockage.

[0027] refer to Figures 1 to 4 As shown, a stainless steel telescopic tube 6 is installed at the air inlet of the vacuum cleaner 2. The stainless steel telescopic tube 6 is heat-resistant and prevents dust from burning through it. A connecting ring 7 is fixedly installed at the air inlet end of the stainless steel telescopic tube 6. An inverted U-shaped clamping plate 8 is fixedly connected to the connecting ring 7. A concave frame 9 is fixedly connected to the lower outer wall of the slag discharge pipe 3. The inverted U-shaped clamping plate 8 and the concave frame 9 are fitted and snapped together. In this structure, the inverted U-shaped clamping plate 8 on the connecting ring 7 is snapped onto the concave frame 9, thereby installing the air inlet end of the stainless steel telescopic tube 6 at the discharge port of the slag discharge pipe 3. Then, when the slag is discharged, the vacuum cleaner 2 is started, thereby sucking the slag and dust generated during the slag discharge into the stainless steel telescopic tube 6 and into the vacuum cleaner 2. This can minimize the dust dispersion during slag discharge and reduce dust pollution.

[0028] refer to Figures 1 to 4As shown, the hydraulic rod 4 is set at an angle downwards, and the hydraulic rods 4 on the left and right side walls of the slag discharge pipe 3 are arranged in a staggered manner.

[0029] refer to Figures 1 to 4 As shown, the vacuum cleaner 2 includes a metal housing 10, a stainless steel telescopic tube 6 connected to the upper part of the metal housing 10, a stainless steel filter 11 detachably installed in the upper part of the metal housing 10, a partition 12 fixedly connected to the lower part of the metal housing 10, an air inlet pipe 13 fixedly connected to the center of the partition 12, a fan 14 fixedly installed at the bottom of the inner cavity of the metal housing 10, the air inlet end of the fan 14 connected to the air inlet pipe 13, and an exhaust pipe 15 fixedly connected to the lower side wall of the metal housing 10, the exhaust pipe 15 connected to the air outlet end of the fan 14. In this structure, the fan 14 is activated to provide suction, thereby sucking out slag and dust. The dust entering the vacuum cleaner 2 will be intercepted and collected by the stainless steel filter 11, and then the filtered air will be discharged from the metal housing 10 through the exhaust pipe 15.

[0030] It should be noted that the metal housing 10 and stainless steel filter 11 mentioned above can prevent high-temperature dust from damaging the vacuum cleaner 2 and the filter, thereby ensuring normal dust removal operation.

[0031] refer to Figures 1 to 4 As shown, multiple casters 16 are fixedly installed on the bottom of the metal housing 10. This structure utilizes the casters 16 to facilitate the movement of the entire vacuum cleaner 2.

[0032] refer to Figures 1 to 4 As shown, the top of the metal housing 10 is hinged to a top cover 17, which is connected to the metal housing 10 by a snap fastener. This structure allows the top cover 17 to be opened so that the stainless steel filter screen 11 can be taken out, making it easier to clean the dust on the stainless steel filter screen 11.

[0033] refer to Figures 1 to 4 As shown, a push handle 18 is fixedly installed on the outer wall of the metal housing 10. This structure makes it easy to push the vacuum cleaner 2.

[0034] It should be noted that the slag discharge pipe in the above embodiments is used for slag discharge from the crude lead-aluminum thermal reduction vessel.

[0035] The implementation principle of the aluminothermic reduction crude lead bottom slag smelting device in this application embodiment is as follows: When the crude lead aluminothermic reduction slag tank 1 is discharging slag, if slag accumulation and blockage occur, the personnel can start the hydraulic rod 4 to drive the crushing cone 5 into the slag discharge pipe 3, and then use the crushing cone 5 to crush the accumulated slag, thereby facilitating normal material discharge from the slag discharge pipe 3 and avoiding blockage.

[0036] Furthermore, when slag is discharged, the blower 14 is activated to provide suction, thereby drawing the slag and dust generated during slag discharge into the stainless steel telescopic pipe 6 and into the vacuum cleaner 2. The dust entering the vacuum cleaner 2 will be intercepted and collected by the stainless steel filter screen 11, and then the filtered air will be discharged from the metal box 10 through the exhaust pipe 15. This can minimize the dust dispersion during slag discharge and reduce dust pollution.
