Description

TECHNICAL FIELD

[0001] The utility model relates to the field of lead smelting technology, especially to a novel dust collecting device. BACKGROUND

[0002] The reduction furnace is an industrial equipment for reduction reaction, mainly used for extracting metal from metal oxide. The lead produced by the reduction furnace is mainly through the reduction smelting process, reducing the lead oxide in the lead-containing raw material (such as lead concentrate, lead slag, etc.) into metal lead. In the prior art, the lead tank of the reduction furnace is generally designed as a movable cover plate. In the actual production process, due to factors such as lead accumulation and slag accumulation, the cover plate usually needs to be opened to discharge lead and slag, resulting in the overflow of flue gas and the emission of a large amount of flue gas into the environment, which does not meet the environmental protection requirements of production and seriously affects the air quality of the production workshop and threatens the safety of the workers. Therefore, we propose a novel dust collecting device. SUMMARY

[0007] In the above-mentioned scheme, an outlet valve is installed on the outlet pipe.

[0008] In the above-mentioned scheme, a limiting plate with a diameter larger than that of the bottom end of the cylinder one is fixed at the bottom end of the closed cylinder one.

[0009] In the above-mentioned scheme, a secondary flue two is connected with the top end of the closed cylinder two, the secondary flue two is connected with the main flue through a flow guide cylinder, a positioning ring with an outer diameter larger than that of the cylinder two is fixed on the outer wall of the closed cylinder two, a support block is fixed on the inner wall of the closed cylinder two, and an annular plate fixed with the drainage cylinder is arranged on the support block.

[0011] In the above scheme, a guide channel is connected between the bottom of the smoke collection hood and the lead trough.

[0012] The advantages and beneficial effects of this utility model are as follows: By setting up a siphon pipe, a setter 1, a setter 2, a smoke collection assembly, and a lead tank, the reduction furnace outputs molten lead into setter 1, and then uses the siphon pipe to draw the molten lead into setter 2. The molten lead is then transported through the lead tank to the electrolysis workshop for further processing.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a novel dust collection device, including a main flue 1, on which a settling device 1 5 and a settling device 2 9 are connected in sequence, and the input end of the settling device 1 5 is connected to the reduction furnace 6.

[0021] Furthermore, the settling device 5 includes a threaded cylindrical body 51 and a closed cylinder 52, which facilitates the disassembly of the settling device 5. Since the settling device 5 serves as a transition container, and the lead liquid moves against gravity under the action of the siphon pipe 15 (described below), the lead liquid will remain inside the settling device 5. Therefore, it is necessary to disassemble the settling device 5 to clean its interior. The upper part of the cylindrical body 51 is connected to a feed trough 54, and the output end of the reduction furnace 6 is connected to a discharge pipe 7 that is sealed to the feed trough 54. A secondary flue 2 is connected between the cylindrical body 51 and the main flue 1, and the flue gas is introduced into the main flue 1 through the secondary flue 2.

[0022] Furthermore, a discharge valve 8 is installed on the discharge pipe 7 to control the discharge flow rate;

[0023] Furthermore, a limiting plate 53 with a diameter larger than that of the bottom end of the cylinder 51 is fixed at the bottom end of the enclosed cylinder 52. The limiting plate 53 is used to position the connection between the two.

[0024] Settling device 2 9 includes a closed cylinder 2 92 and a cylinder 2 91 connected vertically. The closed cylinder 2 92 and the cylinder 2 91 are threaded together. The cylinder 2 91 is provided with an inverted conical drainage cylinder 95. A U-shaped siphon tube 15 is connected between settling device 1 5 and closed cylinder 2 92. The bottom end of the siphon tube 15 is located above the drainage cylinder 95, thereby drawing the lead liquid in settling device 1 5 into settling device 2 9.

[0025] Furthermore, the top of the enclosed cylinder 2 92 is connected to the secondary flue 2 3, and the bottom of the secondary flue 2 3 is rotatably sealed to the enclosed cylinder 2 3, so that the enclosed cylinder 2 92 can be rotated to install and remove the settling device 2 9. The secondary flue 2 3 is connected to the main flue 1 through the guide tube 10. The outer wall of the enclosed cylinder 2 92 is fixed with a positioning ring 93 with an outer diameter larger than that of the cylinder 2 91. The inner wall of the enclosed cylinder 2 92 is fixed with a support block 94. The support block 94 is provided with an annular plate 96 fixed to the diversion tube 95. The diversion tube 95 is installed by utilizing the cooperation between the annular plate 96 and the support block 94.

[0026] The bottom end of the diversion tube 95 is connected to a lead trough 11;

[0027] Furthermore, a vertically arranged connecting tube 97 is fixed at the bottom of the drainage tube 95, and the bottom of the connecting tube 97 is sealed and inserted into the lead groove 11.

[0028] Specifically, by setting up a diversion tube 95 and a connecting tube 97, the diversion tube 97 guides the lead liquid to flow downwards, and the connecting tube 97 increases the length of the lead liquid flow trajectory to prevent the lead liquid from flowing back.

[0029] The lead trough 11 is equipped with a smoke collection assembly connected to the main flue 1. The smoke collection assembly includes a smoke collection hood 13. The smoke collection hood 13 is connected to the main flue 1 through the auxiliary flue 3 4. The auxiliary flue 3 4 is equipped with a smoke exhaust valve 14. The smoke exhaust valve 14 is used to facilitate the control of the exhaust flow rate of the flue gas.

[0030] Furthermore, a guide groove 12 is connected between the bottom of the smoke hood 13 and the lead trough 11, and the guide groove 12 serves as a transition structure between the bottom of the smoke hood 13 and the lead trough 11.

[0031] Specifically, by setting up setter 5, setter 9, smoke collection assembly, and lead tank 11, the reduction furnace 6 outputs molten lead to setter 5. Then, using the negative pressure of the main flue 1, the molten lead is drawn back into setter 9 through the main flue 1, and then transported to the electrolysis workshop for further processing through lead tank 11. Compared with the existing technology, by using the negative pressure of the main flue 1, the flue gas in the lead tank 11 enters the smoke collection hood 13 through the guide channel 12, and then passes through the auxiliary flue 4 to enter the main flue 1, reducing flue gas overflow and preventing large amounts of flue gas from being emitted into the environment, thereby meeting national environmental protection requirements, effectively improving the air quality of the production workshop, and enhancing the safety of the production workshop.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
