Description

Technical Field

[0001] The invention belongs to the technical field of smelting furnaces, and in particular relates to a zinc alloy electric smelting furnace for producing zinc powder. Background Art

[0002] Zinc alloy is an alloy composed of zinc and other elements added. Commonly added alloying elements include low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has a low melting point, good fluidity, and is easy to weld, braze, and plastic process. It is corrosion-resistant in the atmosphere, and residual materials are easy to recycle and remelt. In the zinc powder production process, zinc alloy is often melted and sprayed to produce zinc powder.

[0003] In the prior art, the working method of the zinc alloy electric melting furnace is generally to open the electric melting furnace first, place a certain amount of zinc alloy raw material inside the electric melting furnace, close the electric melting furnace and start heating and melting, and after the zinc alloy is melted, it is output and sprayed, thereby realizing the production of zinc powder by zinc alloy melting.

[0004] While the aforementioned zinc powder production method is feasible, it relies on a single furnace. Frequent opening of the electric furnace during continuous zinc powder production can cause rapid temperature loss within the furnace, leading to significant power loss. Furthermore, this single-furnace production method cannot utilize the furnace's heat to preheat the next batch of zinc alloy raw materials. This results in low zinc powder production efficiency and is not in line with energy conservation and environmental protection. To address this issue, we have developed a zinc alloy electric furnace for zinc powder production to address these challenges. Summary of the Invention

[0040] In this embodiment of the present invention, a second motor 408 is installed on the motor seat on one side of the furnace body carrier 401, and the output shaft of the second motor 408 is connected to the first gear 409.

[0041] like Figure 1As shown, in the initial state, the first melting box 301 is located inside the heating furnace 1 and is coaxial with the heating furnace 1. At this time, the two first channels 101 are sealed by the melting box support frame 303 at the first melting box 301, and the second melting box 302 is located inside the right preheating furnace 2 and is coaxial with the preheating furnace 2. At this time, the second channel 201 and the arc-shaped opening 203 on the right preheating furnace 2 are sealed by the melting box support frame 303 at the second melting box 302. After the same amount of zinc alloy raw materials are placed in the first melting box 301 and the second melting box 302 respectively, the two channels 101 are sealed by the melting box support frame 303 at the first melting box 301. The second control valve 108 on the preheating pipe 104 on the right side of the heating furnace 1 is opened, and the electric heating element on the heating furnace 1 heats the electric melting chamber 103, so that the zinc alloy raw material in the first melt box 301 gradually melts to form a zinc alloy melt. Part of the heat in the electric melting chamber 103 enters the space above the movable cover 105 through the material input port 305, the central radiation hole 306 and the heat radiation port 106, and is then radiated into the preheating chamber 202 through the preheating pipe 104 on the right side. The zinc alloy raw material in the second melt box 302 is preheated by radiating the temperature inside the preheating chamber 202.

[0042] After the zinc alloy raw material inside the first melting box 301 is melted, the hydraulic cylinder 406 controls the lifting drive seat 407 to move upward to push the first lifting seat 109 to move upward synchronously, and the first pushing part 110 pushes the first melting box 301 to move upward. During the upward movement of the first melting box 301, the movable cover 105 is pushed upward until the lower end of the melt outlet pipe 102 is close to the bottom of the first melting box 301. Then, the first control valve 107 is opened and the first melting box 301 is moved upward by an external power device. The zinc alloy melt in 01 is drawn out along the melt outlet pipe 102 to the blowing equipment for blowing processing. After all the zinc alloy melt in the first melt box 301 is drawn out, the hydraulic cylinder 406 controls the lifting drive seat 407 to move downward, and the first lifting seat 109 that moves downward synchronously with the lifting drive seat 407 drives the first pushing part 110 to move gradually downward, and the first melt box 301 that moves downward synchronously drives the movable cover 105 to move gradually downward until the reset is completed.

The first channel 101 is sealed by the melt box supporting frame 303 at the second melt box 302, and then the second control valve 108 on the preheating pipe 104 on the left side of the heating furnace 1 is opened (at this time, the second control valve 108 and the first control valve 107 on the preheating pipe 104 on the right side are both in the closed state), and the electric heating element on the heating furnace 1 heats the electric melting chamber 103 to increase the temperature, so that the preheated zinc alloy raw material in the second melt box 302 gradually melts to form a zinc alloy melt. Part of the heat in the electric melting chamber 103 enters the space above the movable cover 105 through the material input port 305, the central radiation hole 306 and the heat radiation port 106, and is then radiated from the left preheating pipe 104 to the left preheating chamber 202, so that the zinc alloy raw material inside the first melt box 301 is preheated by radiating the temperature inside the preheating chamber 202.

[0044] After the zinc alloy raw material in the second melting box 302 is melted, the lifting drive seat 407 is controlled by the hydraulic cylinder 406 to move upward to push the first lifting seat 109 to move upward synchronously, and the second melting box 302 is pushed upward by the action of the first pushing part 110. During the upward movement of the second melting box 302, the movable cover 105 is pushed upward until the lower end of the melt outlet pipe 102 is close to the bottom of the second melting box 302. Then, the first control valve 107 is opened and the second melting box 302 is moved upward by the external power equipment. The zinc alloy melt in 02 is drawn out along the melt outlet pipe 102 to the blowing equipment for blowing processing. After all the zinc alloy melt in the second melt box 302 is drawn out, the lifting drive seat 407 is controlled to move downward by the hydraulic cylinder 406. The first lifting seat 109 that moves downward synchronously with the lifting drive seat 407 drives the first pushing part 110 to move gradually downward. The second melt box 302 that moves downward synchronously drives the movable cover 105 to move gradually downward until the reset is completed. At this time, the lifting drive seat 407 returns to the initial position.

[0045] Next, the second motor 408 controls the first gear 409 to rotate in the opposite direction, and the meshing action of the first gear 409 and the second gear 412 drives the internal thread seat 411 to rotate in the opposite direction, and the internal thread seat 411 and the thread of the first screw 309 cooperate to drive the first screw 309 to move horizontally in the opposite direction, and the two melt box carrier frames 303 are driven to move to the right synchronously under the action of the first screw 309, until the first melt box 301 returns to the interior of the heating furnace 1 (where the preheated zinc alloy is placed). Raw materials), at this time, the two first channels 101 are sealed by the melt box supporting frame 303 at the first melt box 301, and the second melt box 302 returns to the inside of the right preheating furnace 2 (and the same amount of zinc alloy raw materials are placed in the second melt box 302), at this time, the second channel 201 and the arc-shaped opening 203 on the right preheating furnace 2 are sealed by the melt box supporting frame 303 at the second melt box 302, and then the electric melting of the zinc alloy raw materials to produce zinc powder is continued according to the same control method as above.

[0047] In this embodiment of the present invention, the present invention also includes a second transmission mechanism 6; wherein, the second transmission mechanism 6 includes a second mounting frame 601 (a heat-insulating mounting frame can be used) fixedly mounted on the side surface of the corresponding preheating furnace 2, and a second transmission rod 602 is rotatably mounted on the second mounting frame 601, and a second engaging portion 603 that is threadedly engaged with the second transmission rod 602 is slidably provided on the second mounting frame 601, and a fourth transmission wheel 604 is fixedly mounted on one end of the second transmission rod 602, and the third transmission wheel 505 and the fourth transmission wheel 604 are connected by a second transmission belt 506 (the third transmission wheel 505 and the fourth transmission wheel 604 can be set as a sprocket structure, and the second transmission belt 506 can be set as a metal chain structure to minimize the influence of temperature).

[0048] In this embodiment of the present invention, the present invention further includes a feeding mechanism 7, which is arranged in a one-to-one correspondence with the preheating furnace 2; wherein the feeding mechanism 7 includes an arc-shaped pusher plate 701 slidably arranged inside the corresponding feed channel 211, and a third screw 702 that slides through the feed channel 211 is fixedly arranged on the side surface of the arc-shaped pusher plate 701, and a gear portion 703 is rotatably installed on the side of the feed channel 211 away from the preheating furnace 2, and the gear portion 703 is sleeved on the third screw 702 and the two are threadedly matched; as shown in FIG. Figure 1 As shown, in the initial state, the first melt box 301 is located inside the heating furnace 1 and is coaxial with the heating furnace 1. At this time, the two first channels 101 are sealed by the melt box support frame 303 at the first melt box 301, and the second melt box 302 is located inside the right preheating furnace 2 and is coaxial with the preheating furnace 2. At this time, the second channel 201 and the arc-shaped opening 203 on the right preheating furnace 2 are sealed by the melt box support frame 303 at the second melt box 302, and the arc-shaped push plate 701 on the right feeding mechanism 7 just fits in the side surface of the preheating furnace 2 on the right (specifically, the arc-shaped push plate 701 fits in the arc-shaped blanking port on the preheating furnace 2), and the arc-shaped push plate 701 on the left feeding mechanism 7 is against the inner wall of the feed channel 211 away from the preheating furnace 2.

[0049] A certain amount of zinc alloy raw materials is placed into the left feed channel 211 through the corresponding feed port 212, and the first melting box 301 is controlled to move leftward to the inside of the preheating furnace 2 on the left. At this time, the second melting box 302 is synchronously moved into the inside of the heating furnace 1. In this process, the first transmission wheel 413, the second transmission wheel 504 and the first transmission belt 414 jointly drive the first transmission rod 502 to rotate, and then the third transmission wheel 505, the fourth transmission wheel 604 and the second transmission belt 506 jointly drive the second transmission rod 602 to rotate. The synchronous rotation of the transmission rod 602 drives the first meshing portion 503 and the second meshing portion 603 to move to the left at the same time. Through the meshing action of the first meshing portion 503 on the corresponding gear portion 703, the arc-shaped pusher plate 701 on the left moves to the arc-shaped blanking port on the left preheating furnace 2 (the zinc alloy raw material in the left feed channel 211 is completely pushed into the storage hopper 206), and the arc-shaped pusher plate 701 on the right moves to rest against the inner wall of the feed channel 211 away from the preheating furnace 2. At this time, the same amount of zinc alloy raw material is placed from the corresponding feed port 212 into the feed channel 211 on the right.

[0050] Then, the movable seat 405 is controlled to move to the left to the bottom of the preheating furnace 2 on the left. The lifting driving seat 407 is controlled to move upward to push the second lifting seat 204 on the left to move upward synchronously. Under the action of the corresponding second pushing part 205, the first melting box 301 is pushed upward to enter the guide ring body 207. When the top of the first melting box 301 contacts the conical material guide platform 208, the conical material guide platform 208 is pushed upward synchronously until the material input port 305 on the first melting box 301 is just connected with the inner cavity of the storage hopper 206. At this time, the zinc alloy raw material in the inner cavity of the storage hopper 206 slides along the material input port 305 into the first melting box 301, thereby realizing the loading operation of the first melting box 301. After the loading is completed, the lifting drive seat 407 is controlled to move downward to complete the reset, and then the first melting box 301 is controlled to move rightward to the inside of the heating furnace 1. At this time, the second melting box 302 is synchronously moved to the inside of the preheating furnace 2 on the right (that is, the first melting box 301 and the second melting box 302 return to their initial positions). In this process, the first transmission wheel 41 is used to move the first melting box 301 to the inside of the heating furnace 1. 3. The second transmission wheel 504 and the first transmission belt 414 work together to drive the first transmission rod 502 to rotate in the opposite direction, and then the third transmission wheel 505, the fourth transmission wheel 604 and the second transmission belt 506 work together to drive the second transmission rod 602 to rotate in the opposite direction. Thus, through the synchronous rotation of the first transmission rod 502 and the second transmission rod 602, the first meshing portion 503 and the second meshing portion 603 are driven to move to the right at the same time. The meshing action of the first meshing portion 503 on the corresponding gear portion 703 causes the arc-shaped push wheel 503 on the left to move to the right. The material plate 701 moves back to its initial position (i.e., the arc-shaped push plate 701 on the left moves to rest against the inner wall of the feed channel 211 away from the preheating furnace 2, and at this time, the same amount of zinc alloy raw materials are placed into the feed channel 211 on the left from the corresponding feed port 212), and the arc-shaped push plate 701 on the right moves back to its initial position (i.e., the arc-shaped push plate 701 on the right moves to the arc-shaped blanking port on the right preheating furnace 2, and the zinc alloy raw materials in the right feed channel 211 are completely pushed into the storage hopper 206).

[0051] Then, by controlling the movable seat 405 to move rightward to the bottom of the preheating furnace 2 on the right, the lifting driving seat 407 is controlled to move upward to push the second lifting seat 204 on the right to move upward synchronously, and under the action of the corresponding second pushing portion 205, the second melting box 302 is pushed upward to enter the inside of the guide ring body 207. When the top of the second melting box 302 contacts the conical material guide platform 208, the conical material guide platform 208 is pushed upward synchronously until the material input port 305 on the second melting box 302 is just connected to the inner cavity of the storage hopper 206. At this time, the zinc alloy raw material in the inner cavity of the storage hopper 206 slides along the material input port 305 into the second melting box 302, thereby realizing the loading operation of the second melting box 302. After the loading is completed, the lifting drive seat 407 is controlled to move down to complete the reset. Then, according to the electric melting and preheating control method of the specific embodiment 1, the zinc alloy raw material in the first melting box 301 is melted while the zinc alloy raw material in the second melting box 302 is preheated. The zinc alloy melt in the first melting box 301 is drawn out along the melt outlet pipe 102. After the blowing process is completed in the blowing equipment, the first melting box 301 and the second melting box 302 are controlled to move synchronously to the left to the specified position again, and the moving seat 405 is controlled to move to the left to the bottom of the preheating furnace 2 on the left. During the electric melting process of the preheated zinc alloy raw material in the second melting box 302, the loading operation of the first melting box 301 is realized again, and the zinc alloy raw material in the first melting box 301 is preheated by heat radiation. The zinc alloy melt in the second melting box 302 is discharged along the melt outlet pipe 102. After being drawn out to the blowing equipment for blowing processing, the first melt box 301 and the second melt box 302 are controlled to move synchronously to the right back to the initial position, and the movable seat 405 is controlled to move to the right to just below the preheating furnace 2 on the right. During the electric melting process of the preheated zinc alloy raw material inside the first melt box 301, the loading operation of the second melt box 302 is realized again, and the zinc alloy raw material in the second melt box 302 is preheated by heat radiation. According to the above control method, the processing of the zinc alloy raw materials can be realized successively.
