[0023] S1. The zinc and lead solid waste to be treated is transported to the pretreatment chamber of the pretreatment mechanism through the transportation mechanism, and the hydraulic cylinder is started to press the lower pressure block downward to perform preliminary compaction and crushing treatment on the solid waste. Then, the push plate is pushed by the push-pull device to push the pretreated solid waste from the other side of the pretreatment chamber to the movable plate, and is ready to enter the next step of transmission. The screw is driven to rotate by the third motor to drive the threaded sleeve and the moving frame to move along the line groove. When the screw is lifted to the same horizontal position as the sliding plate, the relative position between the movable plate and the sliding plate is adjusted, and the movable plate is raised by rotating the screw cap, so that the zinc and lead solid waste that has been preliminarily treated in the movable plate can slide smoothly into the transportation mechanism;

[0025] S3. In the solid waste treatment mechanism, the heating mechanism is started in advance, the refining furnace body is heated by the heating plate, and the temperature inside the furnace body is efficiently insulated by refractory bricks, and then the first motor is started to drive the stirring shaft and the stirring rod to rotate, and the scraper scrapes the inner wall of the solid waste tank at the same time to ensure that the solid waste is evenly heated and promote the refining efficiency. The waste gas generated during the refining process enters the waste gas purification mechanism through the exhaust pipe. In the purification box, the waste gas passes through the preset path of the guide plate and is purified by the purification liquid sprayed by the spray head of the spray mechanism, and then the circulating pump is used to circulate the purification liquid in the circulating pipe and the branch pipe to improve the purification efficiency. The purified waste gas is discharged from the gas outlet, which meets the environmental protection requirements;

[0026] S4. After the refining is completed, the molten raw materials and waste slag are separated at the bottom of the solid waste trough by the through holes and the discharge channel. The waste slag remains in the solid waste trough, and the molten raw materials obtained by refining flow out through the mesh holes on the solid waste trough. The valve body is opened to collect the refined alloy raw materials. By controlling the continuous operation of the transmission mechanism and the pretreatment mechanism, and the coordinated work of the heating mechanism and the exhaust gas purification mechanism, efficient and environmentally friendly recycling of zinc and lead solid wastes can be achieved.

[0027] The beneficial effects of the present invention are:

[0028] First, the alloy refining furnace of the present invention realizes efficient treatment of zinc and lead solid wastes by optimizing the design of the solid waste treatment mechanism. The stirring shaft and the stirring rod in the solid waste treatment mechanism can ensure that the solid waste is evenly heated during the refining process. At the same time, the cross-section of the scraper is arc-shaped, which better fits the refining furnace body and can scrape the inner wall of the solid waste trough to prevent the solid waste from accumulating in the trough. After the refining is completed, the molten raw material and the waste slag are separated by the through holes and the discharge channel at the bottom of the solid waste trough, and the waste slag remains in the solid waste trough. The molten raw material obtained by refining flows out through the mesh holes on the solid waste trough, and the valve body is opened to collect the alloy raw materials obtained by refining. In addition, the heating mechanism is arranged around the inner wall of the refining furnace body, which can realize uniform control of the temperature in the furnace and further improve the refining efficiency.

[0029] Second, the present invention sets a waste gas purification mechanism in the refining furnace, which purifies the waste gas generated in the refining process through the spray mechanism. In the purification box, the waste gas passes through the preset path of the guide plate and the spray head of the spray mechanism for spray purification, and then the circulating pump is used to circulate the purification liquid in the circulating pipe and the branch pipe to improve the purification efficiency. The purified waste gas is discharged from the outlet, which meets the environmental protection requirements.

[0030] Third, the alloy refining furnace of the present invention realizes the whole process of automated control from solid waste pretreatment, transmission, refining to waste gas treatment. The zinc and lead solid waste to be treated is transported to the pretreatment mechanism for preliminary treatment through the transportation mechanism, and then the pretreated solid waste is sent to the refining furnace body for refining through the transportation mechanism. During the refining process, the heating mechanism and the waste gas purification mechanism work together to ensure the refining efficiency and environmental protection performance. After the refining is completed, the molten raw materials and waste slag are separated by the solid waste treatment mechanism, realizing the efficient recovery of alloy raw materials. During the whole process, the operator only needs to perform simple monitoring and adjustment, which greatly reduces the labor intensity and improves the work efficiency.

[0059] A pre-treatment mechanism 6, which is arranged on the side of the transmission mechanism 5 and is arranged corresponding to the solid waste treatment mechanism 2, and is used for crushing zinc and lead solid wastes;

[0060] A transport mechanism 7 is provided on the front side of the pretreatment mechanism 6, and the transport mechanism 7 is used to transport the zinc and lead solid wastes to be treated to the pretreatment mechanism 6 for processing.

[0061] In one embodiment provided by the present invention, Figure 3 As shown, a furnace cover 101 is disposed at the top of the refining furnace body 1 , an exhaust pipe 103 penetrating into the interior of the refining furnace body 1 is disposed on the furnace cover 101 , and a support leg 102 is disposed around the outer bottom side of the refining furnace body 1 .

Refractory bricks 303 are provided in the inner ring of the heating chamber 302. A flue 304 connected to the heating chamber 302 is provided outside the refining furnace body 1.

[0065] Specifically, the heating plate 301 generates heat and transfers it to the solid waste in the furnace through the heating chamber 302.

The refractory bricks 303 effectively keep the temperature inside the furnace body warm, thereby improving the heating efficiency. The exhaust gas generated during the heating process is discharged through the flue 304 for subsequent treatment.

[0066] In another embodiment provided by the present invention, Figure 5 and 6As shown, the exhaust gas purification mechanism 4 includes a purification box 401 arranged beside the refining furnace body 1, a spray mechanism 402 is arranged in the purification box 401, an air inlet 403 and an air outlet 404 are arranged at the upper and lower ends of the purification box 401, and the air outlet 404 is connected to the exhaust pipe 103 on the refining furnace body 1, a sleeve plate 406 is sleeved on the upper end of the outside of the purification box 401, and an arc plate 405 is correspondingly fitted on the outside of the purification box 401 below the sleeve plate 406, and a support frame 409 for support is arranged at the bottom end of the purification box 401;

In the purification box 401, the exhaust gas passes through the preset path of the guide plate 4021 and is sprayed and purified by the spray head 4023 of the spray mechanism 402. The exhaust gas is neutralized, absorbed, and other treatments by the liquid such as alkali solution sprayed by the spray head 4023 of the spray mechanism 402 to remove harmful substances in the exhaust gas. The guide plate 4021 causes the exhaust gas to form turbulence in the purification box 401, thereby increasing the contact area between the exhaust gas and the spraying liquid and improving the purification efficiency. The treated exhaust gas is discharged from the air outlet 404, and then the circulating pump 408 is used to circulate the purified liquid in the circulating pipe 407, the main pipe 4025, and the branch pipe 4024, thereby improving the purification efficiency and saving resources.

[0071] Specifically, the pretreatment mechanism 6 performs preliminary treatment on the solid waste so as to better refine it. The solid waste enters the pretreatment chamber 601 through the feed plate 602. The hydraulic cylinder 603 drives the lower pressing block 604 to compact and crush the solid waste, thereby reducing the volume of the solid waste and improving the refining efficiency. Then, the pusher 616 is used to push the push plate 617 to push the pretreated solid waste from the other side of the pretreatment chamber 601 onto the movable plate 614, ready for the next step of transmission. The third motor 608 drives the screw rod 609 to rotate, driving the threaded sleeve 610 and the movable frame 606 to move along the line groove 605. When the screw rod 609 is lifted to the same horizontal position as the sliding plate 504, the relative position between the movable plate 614 and the sliding plate 504 is adjusted, and the movable plate 614 is lifted by rotating the screw cap 615, so that the zinc and lead-containing solid waste that has been preliminarily treated in the movable plate 614 can slide smoothly into the transmission mechanism 5.

[0073] Specifically, the transmission mechanism 5 is responsible for transmitting the pre-treated solid waste from the movable plate 614 to the refining furnace body 1, and sending the solid waste from the feed hopper 503 through the joint between the sliding plate 504 and the movable plate 614 into the transmission cylinder 502. The second motor 508 drives the screw 506 to rotate in the transmission cylinder 502 through the synchronous part 509. As the screw 506 rotates, the solid waste is gradually pushed to the discharge pipe 505 and finally enters the refining furnace body 1 for refining.

[0074] The treatment process of zinc- and lead-containing solid waste of the present invention comprises:

Then, the pusher 616 is used to push the push plate 617 to push the pretreated solid waste from the other side of the pretreatment chamber 601 to the movable plate 614, ready for the next step of transmission. The screw rod 609 is driven to rotate by the third motor 608, driving the threaded sleeve 610 and the movable frame 606 to move along the line groove 605. When the screw rod 609 is driven to move to the same horizontal position as the sliding plate 504, the relative position between the movable plate 614 and the sliding plate 504 is adjusted, and the movable plate 614 is raised by rotating the screw cap 615, so that the zinc and lead solid waste that has been preliminarily treated in the movable plate 614 can slide smoothly into the transportation mechanism 5.

[0076] S2, the pre-treated solid waste falls into the feed hopper 503 of the transmission mechanism 5 and enters the transmission cylinder 502, the second motor 508 is started, and the screw 506 is driven to rotate through the synchronous member 509, so that the solid waste is pushed forward along the transmission cylinder 502, until it passes through the discharge pipe 505 and enters the solid waste treatment mechanism 2 in the refining furnace body 1;

[0077] S3.
