Description

Technical Field

[0001] This application relates to the technical field of aluminum smelting, and specifically relates to a temperature compensation device for a side furnace aluminum liquid pump. Background Art

[0002] The side furnace aluminum liquid pump is an important tool used in smelting equipment such as side shaft furnaces for aluminum liquid circulation and transfer. During the aluminum smelting process, after circulation or transfer, the side furnace aluminum liquid pump can send the aluminum liquid back into the furnace or other required places, which can effectively improve the utilization rate of aluminum liquid and reduce the waste and burning loss of aluminum liquid. When the aluminum liquid is circulated or transferred through the aluminum liquid pump, due to the high temperature of the aluminum liquid or the influence of the transmission pipeline, the temperature of the aluminum liquid may be affected during the transfer process, so a temperature compensation device is required to compensate and calibrate the temperature of the aluminum liquid to keep the output of the aluminum liquid constant or meet the expectations.

[0003] The existing temperature compensation device for side furnace aluminum liquid pumps usually consists of a heat preservation cover, a gas inlet pipe, an ignition device, and a thermocouple. There is a flame nozzle on the ignition device, and the flame nozzle is located inside the side furnace. The ignition device can ignite the gas and then transmit heat into the side furnace through the flame nozzle to heat the inside of the side furnace, and heat preservation is achieved by the heat preservation cover.

[0004] Although the above device realizes the temperature compensation of the aluminum liquid in the side furnace, usually, in order to meet the production requirements, the side furnace is relatively large in volume, and the aluminum liquid in the side furnace is usually measured in cubic meters, liters, or tons. When the temperature of the inside of the side furnace is compensated by the temperature compensation device, the aluminum liquid near the ignition device is often heated faster, while the aluminum liquid in other positions needs to wait for a certain period of time to reach the target temperature. At the same time, during the heating process, a large amount of flue gas is generated during the combustion of the ignited gas, and this flue gas often directly discharges from the side furnace. In order to avoid uneven heating of the aluminum liquid in the side furnace, it is necessary to provide a temperature compensation device for a side furnace aluminum liquid pump to solve the above problems.

[0038] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0039] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0040] Embodiment 1: This embodiment mainly introduces the basic structure and working principle of the temperature compensation device for the side furnace aluminum liquid pump. Specifically:

[0041] As Figure 1 - Figure 2 shown, this application provides a temperature compensation device for a side furnace aluminum liquid pump, including a base 1, which is a supporting part of the aluminum liquid side furnace, so that the side furnace can be placed stably on the ground without direct contact with the ground. A furnace body 2 for temporarily storing aluminum liquid is fixedly installed on the base 1, and this furnace body 2 is the side furnace body;

[0042] A thickening layer 4 is fixedly installed on the furnace body 2. This thickening layer 4 is mainly made of heat-insulating material, and its purpose is to insulate the furnace body 2 to a certain extent. A temperature control component 3 is fixedly installed on one side of the base 1. This temperature control component 3 mainly includes a gas inlet pipe, an ignition device, a thermocouple, a combustion-supporting device, etc. As Figure 3 shown, one side of this temperature control component 3 extends into the furnace body 2 and is provided with a burner nozzle 31. After being ignited, the flame can be directly sprayed into the furnace body 2 through the burner nozzle 31. This temperature control component 3 is mainly used to quickly transfer heat into the furnace body 2 to achieve temperature compensation for the aluminum liquid;

[0043] This temperature control component 3 also includes an aluminum liquid pump for pumping aluminum liquid from the main furnace into the furnace body 2. An inlet port (not marked in the figure) is opened on the side of the furnace body 2 away from the burner nozzle 31. After the aluminum liquid pump pumps the aluminum liquid in the main furnace, the aluminum liquid can be transported into the furnace body 2 through the inlet port. If there is a temperature loss during the transportation of the aluminum liquid by the aluminum liquid pump, the ignition device can be started to compensate the temperature of the aluminum liquid;

[0044] However, when heating the inside of the furnace body 2 through the ignition device, the flame for heating will inevitably generate flue gas during combustion. If this flue gas is not treated, it will remain in the furnace body 2 for a long time and cannot be discharged, which will undoubtedly affect the purity of the aluminum liquid. To solve this problem, as Figure 3As shown, a smoke exhaust hood 32 is fixedly installed inside the furnace body 2. The smoke exhaust hood 32 is located directly above the burner nozzle 31 to collect the flue gas after the flame sprayed by the burner nozzle 31 burns. A smoke exhaust pipe 33 is fixedly installed on one side of the smoke exhaust hood 32. Usually, the smoke exhaust pipe 33 penetrates the furnace body 2 and extends to the outside of the furnace body 2, and a negative pressure fan is installed on the other side of the smoke exhaust pipe 33, so that the flue gas can be directly discharged from the furnace body 2;

[0045] Furthermore, in order to avoid slow temperature compensation caused by local heating of the molten aluminum in the furnace body 2, the flue gas can be further utilized, such as Figure 3 - Figure 4 As shown, a cavity is formed in the thickening layer 4, and a compensation assembly 5 is arranged in the cavity. The compensation assembly 5 includes a main shaft 52 arranged in the cavity. One side of the main shaft 52 is movably connected to the thickening layer 4 through a bearing, and the other side of the main shaft 52 is fixedly installed with a motor 51. The output end of the motor 51 is fixedly connected to the main shaft 52. When the motor 51 is started, the main shaft 52 can be driven to rotate. A bracket is fixedly installed at the bottom of the motor 51, and the bracket is fixedly connected to the side surface of the thickening layer 4. Since the motor 51 is an electrical component, in order to avoid damaging the motor 51 due to excessive temperature in the thickening layer 4 and the furnace body 2, the motor 51 is located outside the furnace body 2 and the thickening layer 4, but the main shaft 52 is located in the cavity of the thickening layer 4, and the main shaft 52 is made of heat-resistant material;

[0046] A first vertical plate 54 is fixedly installed on the main shaft 52. The first vertical plate 54 is vertically installed, and the top of the first vertical plate 54 is close to the top of the cavity of the thickening layer 4. When the main shaft 52 rotates under the start of the motor 51, the first vertical plate 54 rotates synchronously. A first coiled pipe 55 is fixedly installed on the first vertical plate 54. The first coiled pipe 55 is coiled around the first vertical plate 54. It should be noted that usually, the furnace body 2 is of a flat design. Similarly, the main shaft 52 has a long distance in the horizontal direction, and the first vertical plate 54 is arranged with the main shaft 52 as the long axis, so that Figure 3 Taking the perspective in [the relevant figure] as the standard, the front view of the first vertical plate 54 is a rectangle, which has a relatively wide width, while its height is lower than the height of the cavity. Looking from the side, the width of the first vertical plate 54 is relatively narrow and smaller than the diameter of the main shaft 52;

[0047] And the first coiled pipe 55 coiled around the first vertical plate 54 can be specifically referred to Figure 3 - Figure 4, which is stacked and wound around the surface of the first vertical plate 54, and the number of stacked layers is based on the height of the first vertical plate 54. From a top-down perspective, the first coiled pipe 55 is arranged in an oval shape. The arrangement of the first coiled pipe 55 is similar to that of an existing mountain road, which can extend the length of the first coiled pipe 55 as much as possible without affecting the flow of flue gas. At the same time, multiple groups of small brackets are also provided on the first vertical plate 54. The small brackets are located at the bottom of each pipeline of the first coiled pipe 55 and play a supporting role for the first coiled pipe 55;

[0048] On one side of the main shaft 52 close to the burner nozzle 31, an air inlet disk 6 is movably connected through a bearing. The inside of the air inlet disk 6 is hollow to facilitate the temporary storage of flue gas. It should be noted that the upper half of the air inlet disk 6 is located in the cavity of the thickened layer 4, and its lower half is located in the furnace body 2. And a gasket is provided on the surface of the air inlet disk 6 to prevent heat from escaping from the furnace body 2 into the cavity. In this embodiment, the other end of the exhaust pipe 33 does not penetrate the furnace body 2, and the other end of the exhaust pipe 33 is connected to the lower half of the air inlet disk 6. Since the air inlet disk 6 is connected to the main shaft 52 by a bearing, when the main shaft 52 rotates, the air inlet disk 6 will not rotate and will not affect the exhaust pipe 33;

[0049] Continue to refer to Figure 3 - Figure 4 , at one end of the main shaft 52 far from the air inlet disk 6, a first exhaust cylinder 56 is fixedly installed. The first exhaust cylinder 56 is mainly composed of a vertical cylinder fixedly installed on the main shaft 52 and an exhaust pipe fixedly installed on one side of the vertical cylinder. The vertical cylinder is hollow, and the exhaust pipe is connected to the vertical cylinder. An exhaust disk 7 is provided on one side of the exhaust pipe. The exhaust disk 7 is movably connected to the main shaft 52 through a bearing. Similarly, the inside of the exhaust disk 7 is hollow. An exhaust pipe 74 is fixedly installed on one side of the exhaust disk 7. The exhaust pipe 74 penetrates the furnace body 2 and extends to the outside of the furnace body 2. A negative pressure pump is installed at the other end of the exhaust pipe 74 to suck the flue gas in the first coiled pipe 55;

[0050] The starting end of the first coil pipe 55 is located inside the air inlet disc 6 and is in communication with the air inlet disc 6. The end of the first coil pipe 55 is in communication with the vertical cylinder. Thus, the flue gas located in the exhaust pipe 33 is adapted to enter the air inlet disc 6 under the action of the negative pressure pump, then enter the first coil pipe 55 through the air inlet disc 6, enter the first exhaust cylinder 56 through the first coil pipe 55, and finally enter the exhaust disc 7 through the first exhaust cylinder 56 and be discharged through the exhaust pipe 74. When there is flue gas at the exhaust pipe 74, it means that the first coil pipe 55 is already filled with flue gas. In this application, since the first coil pipe 55 is arranged in a coiled manner and its total length is relatively long, the negative pressure pump will have its effect reduced due to the length of the first coil pipe 55, and the negative pressure effect at the exhaust pipe 33 is relatively small, but it can still suck the flue gas into the exhaust pipe 33. In this way, the time for the flue gas to stay in the first coil pipe 55 will also be relatively long. The purpose is to suck the flue gas generated during flame combustion into the exhaust pipe 33 for the first time and enter the first coil pipe 55. At this time, the flue gas has a relatively high temperature and can heat the first coil pipe 55 and each pipeline. When the first coil pipe 55 is heated, it will dissipate heat into the cavity, and the temperature in the cavity will also increase, which can better insulate the upper half of the furnace body 2. In this application, each component located inside the thickened layer 4 and inside the furnace body 2 is made of heat-resistant material, and the purpose is to prevent deformation and damage under the action of high temperature;

[0051] As Figure 3 、 Figure 6 shown, a sealing plate 53 is fixedly installed at the bottom of the main shaft 52. At the same time, a notch is opened at the top of the furnace body 2. The sealing plate 53 is adapted to the notch. The sealing plate 53 is symmetrically arranged along the axis of the main shaft 52. In the initial state, the sealing plate 53 is horizontally placed. When the main shaft 52 rotates 180 degrees, the sealing plate 53 returns to the horizontal state. It should be noted that, taking Figure 6 as a reference, the height of the first vertical plate 54 is lower than half of the length of the front and back of the sealing plate 53. Thus, when the main shaft 52 drives the first vertical plate 54 to flip, the first vertical plate 54 is adapted to enter the furnace body 2 through the notch;

[0052] In this embodiment, annular sliding grooves are opened on both the air inlet disc 6 and the exhaust disc 7. When the first coil pipe 55 rotates, the end of the first coil pipe 55 connected to the air inlet disc 6 and the end of the first coil pipe 55 connected to the exhaust disc 7 rotate in the sliding grooves, and it will not affect the rotation of the first coil pipe 55;

[0053] To sum up, as Figure 3 - Figure 4As shown, in the initial state, the first vertical plate 54 is placed in the cavity of the thickened layer 4 in a vertical state, and the first sealing plate 53 is placed horizontally. At this time, the furnace body 2 and the cavity are not connected to each other. When the ignition device is started to heat the inside of the furnace body 2, the smoke enters the air inlet plate 6 through the smoke exhaust pipe 33, and then enters the first coil 55, and is spread all over the inside of the first coil 55 to heat the first coil 55. Then the smoke passes through the first exhaust pipe 56 and the exhaust plate 7 and is finally discharged through the exhaust pipe 74. When the smoke is in the first coil 55, the first coil 55 will also emit hot air to heat the cavity. After the cavity is heated, a small amount of heat will be transmitted to the furnace body 2 through the inner wall of the thickened layer 4 and the sealing plate 53, which plays a certain role in compensating the temperature of the furnace body 2.

[0054] When it is necessary to quickly and comprehensively compensate the temperature in the furnace body 2, the staff can start the motor 51, and the motor 51 drives the main shaft 52 to rotate. During the rotation of the main shaft 52, the first vertical plate 54, the first coil 55 and the sealing plate 53 rotate synchronously. When the sealing plate 53 rotates, it is staggered with the notch on the furnace body 2. At this time, the furnace body 2 and the cavity of the thickened layer 4 are in a connected state. Because the flue gas has previously covered the first coil 55, there is also a lot of heat in the cavity. Therefore, when the furnace body 2 is connected to the cavity, it will not lose too much heat. After the main shaft 52 rotates 180 degrees, the first vertical plate 54 and the first coil 55 rotate into the furnace body 2. At this time, the first vertical plate 54 The first coil 55 is placed vertically in the furnace body 2, and the sealing plate 53 is restored to a horizontal state after rotating 180 degrees to fill the gap, and the furnace body 2 and the cavity are restored to a state of being disconnected from each other. Since the first coil 55 is located in the furnace body 2 at this time, the heat emitted by the first coil 55 will directly heat the interior of the furnace body 2, and since the first coil 55 is arranged in multiple layers, the heat emitted from the first coil 55 will be more dense. At the same time, the first vertical plate 54 has a certain height, and the turned first coil 55 will also occupy a certain height in the furnace body 2. Within this height range, it will be more intuitively heated by the auxiliary heating of the first coil 55;

[0055] It should be noted that in this application, in order to avoid damage to the first vertical plate 54 and the first coil pipe 55, the highest liquid level of the molten aluminum in the furnace body 2 will not contact the first vertical plate 54 or the first coil pipe 55. Secondly, the motor 51 can be controlled to start during preheating to drive the first vertical plate 54 and the first coil pipe 55 to turn into the furnace body 2. At this time, no molten aluminum has been input into the furnace body 2. After preheating to a certain temperature, the motor 51 is then controlled to rotate back, driving the first vertical plate 54 and the first coil pipe 55 to rotate, and then molten aluminum can be injected. It should also be noted that there is a certain distance between the side of the first coil pipe 55 close to the burner 31 and the burner 31 to prevent the flame generated when the gas is ignited from directly burning the first coil pipe 55. There is also a certain distance between the smoke exhaust hood 32 and the sealing plate 53, and when the sealing plate 53 rotates, it will not contact the smoke exhaust hood 32;

[0056] Furthermore, when there is only one row of the first coil pipe 55 and the first vertical plate 54, the heating effect on the furnace body 2 is limited. As Figure 4 shown, a second vertical plate 541 and a third vertical plate 542 are also fixedly installed on the main shaft 52 in the counterclockwise direction. Both the second vertical plate 541 and the third vertical plate 542 are fixedly connected to the main shaft 52. Similarly, a second coil pipe 551 is wound and installed on the second vertical plate 541, and a third coil pipe 552 is wound and installed on the third vertical plate 542. The installation method, arrangement method, and effect of the second coil pipe 551 and the third coil pipe 552 are the same as those of the first coil pipe 55. In this embodiment, the height of the second vertical plate 541 is lower than that of the first vertical plate 54, and the height of the third vertical plate 542 is lower than that of the second vertical plate 541, so as to prevent the second vertical plate 541 and the third vertical plate 542 from colliding with the inner wall of the cavity, the notch, or the inner wall of the furnace body 2 when the main shaft 52 drives them to rotate;

[0057] Refer to Figure 5 , the initial ends of the first coil pipe 55 communicate with the initial ends of the second coil pipe 551 and the third coil pipe 552 respectively. Therefore, after the flue gas coming in through the air inlet disc 6 enters the first coil pipe 55, it will be split and flow into the first coil pipe 55 and the second coil pipe 551;

[0058] Refer to Figure 4 , a second exhaust cylinder 561 and a third exhaust cylinder 562 are respectively arranged on the first exhaust cylinder 56 in the counterclockwise direction. Both the second exhaust cylinder 561 and the third exhaust cylinder 562 communicate with the first exhaust cylinder 56. At the same time, the end of the second coil pipe 551 communicates with the second exhaust cylinder 561, and the end of the third coil pipe 552 communicates with the third exhaust cylinder 562. Therefore, the flue gas in the second coil pipe 551 and the third coil pipe 552 will enter the first exhaust cylinder 56 through the second exhaust cylinder 561 and the third exhaust cylinder 562, and finally be discharged together through the exhaust pipe 74;

[0059] Thus, when the main shaft 52 rotates, it will drive the first vertical plate 54, the second vertical plate 541 and the third vertical plate 542 to rotate synchronously. At the same time, the first coil pipe 55, the second coil pipe 551 and the third coil pipe 552 will rotate synchronously. After rotating 180 degrees, the first coil pipe 55, the second coil pipe 551 and the third coil pipe 552 are located inside the furnace body 2, and the heat they emit will fill the inside of the furnace body 2 to achieve rapid heating of the furnace body 2. Compared with only heating the inside of the furnace body 2 through the first coil pipe 55, this heating method is faster and more comprehensive;

[0060] In this embodiment, the second coil pipe 551 and the third coil pipe 552 can also be understood as the extension ends of the first coil pipe 55. The main purpose is to extend the pipeline so that the flue gas can stay in the pipeline for a longer time to exert its waste heat effect. By arranging the second coil pipe 551 and the third coil pipe 552 at different positions, it is convenient to heat different positions inside the furnace body 2, making the heating inside the furnace body 2 more comprehensive.

[0061] Embodiment 2: The above embodiment realizes rapid heating of different positions inside the furnace body 2 by providing the first coil pipe 55, the second coil pipe 551 and the third coil pipe 552. However, since only annular sliding grooves are provided on the air inlet disc 6 and the exhaust disc 7, which adapts to the flipping of the coil pipes. But during use, the flue gas inside the air inlet disc 6 and the exhaust disc 7 will escape into the cavity of the thickened layer 4 through the sliding grooves, and there will also be certain impurities in the flame generated by the combustion of the fuel gas. If not filtered, it will directly enter the coil pipes. Since the coil pipes are arranged in a coiled manner, it is very difficult to remove the impurities from the coil pipes after they enter;

[0062] To solve this problem, in this embodiment, the sliding grooves on the air inlet disc 6 and the exhaust disc 7 are further defined, and at the same time, the structures of the air inlet disc 6 and the exhaust disc 7 are further defined, as Figure 7 - Figure 9 shown, the air inlet disc 6 includes a first disc body 61 installed on the main shaft 52 through a bearing. One side of the first disc body 61 close to the first coil pipe 55 is provided with an opening. A rotating disc 62 is fixedly installed on the main shaft 52. A slide rail 621 is fixedly installed on the outer ring of the rotating disc 62. At the same time, a slide groove 63 is opened at the opening of the first disc body 61. The slide rail 621 is slidably installed in the slide groove 63. At the same time, a through hole is opened on the rotating disc 62. The initial end of the first coil pipe 55 is adapted to and fixedly connected to the through hole. Thus, when the main shaft 52 drives the first coil pipe 55 to rotate, the rotating disc 62 will rotate synchronously, and the slide rail 621 rotates in the slide groove 63;

[0063] A partition plate 69 is fixedly installed inside the first disk body 61. The partition plate 69 divides the inside of the first disk body 61 into two groups of chambers. For the convenience of description, the chamber between the partition plate 69 and the rotating disk 62 is defined as the first chamber, and the chamber between the partition plate 69 and the other side of the first disk body 61 is defined as the second chamber. The exhaust pipe 33 communicates with the second chamber. At the same time, a first arc-shaped groove 64 is opened on the partition plate 69. The first arc-shaped groove 64 does not penetrate the partition plate 69. At the same time, a first opening 641 and a second opening 642 are respectively opened at both ends of the first arc-shaped groove 64. The first opening 641 and the second opening 642 penetrate the first arc-shaped groove 64. It should be noted that in the initial state, the through hole on the rotating disk 62 corresponds to the position of the first opening 641. At the same time, the second opening 642 is located at a position close to 180 degrees after the rotation of the first opening 641, but does not reach 180 degrees. And the diameters of the first opening 641 and the second opening 642 are both larger than the through hole. When the through hole rotates 180 degrees driven by the main shaft 52, the through hole will still communicate with the second opening 642;

[0064] In the initial state, the through hole corresponds to the position of the first opening 641. At this time, the initial end of the first coil pipe 55 communicates with the second chamber, and the flue gas can directly enter the first coil pipe 55. When the main shaft 52 drives the through hole to rotate 180 degrees, the through hole corresponds to the second opening 642. At this time, the flue gas can enter the through hole through the second opening 642 and then enter the first coil pipe 55. Since the first arc-shaped groove 64 does not penetrate the partition plate 69, during the rotation process, the through hole is blocked by the first arc-shaped groove 64, and at this time, the first coil pipe 55 will not intake smoke;

[0065] For the convenience of purifying the flue gas, as Figure 7 、 Figure 9 and Figure 11 shown, filter cartridges 65 are provided at both the first opening 641 and the second opening 642. An installation sleeve 651 is fixedly installed at one end of the filter cartridge 65 close to the partition plate 69. A fixed sleeve 68 is slidably installed on the outer ring of the installation sleeve 651. The fixed sleeve 68 is fixedly connected to the partition plate 69. When there is no external force, the filter cartridge 65 will not rotate. The filter cartridge 65 filters the flue gas entering the first opening 641 or the second opening 642 to prevent impurities from directly entering the first coil pipe 55;

[0066] As Figure 8 、 Figure 10As shown in the figure, the exhaust disk 7 includes a second disk body 71 movably mounted on the main shaft 52 through a bearing. A baffle 72 is slidably mounted in the second disk body 71. The baffle 72 is similar to the rotating disk 62 in the intake disk 6. A second arc-shaped groove 73 is formed on the surface of the exhaust disk 7. At the same time, a third opening 721 is formed on the baffle 72. The end of the exhaust pipe on the first exhaust cylinder 56 communicates with the third opening 721, and the exhaust pipe is fixedly connected to the baffle 72. When the first exhaust cylinder 56 rotates driven by the main shaft 52, the baffle 72 rotates synchronously, and the exhaust pipe slides in the second arc-shaped groove 73. While not affecting the discharge of the flue gas, the baffle 72 prevents the flue gas from flowing back from the second arc-shaped groove 73;

[0067] In the initial state, the first coiled pipe 55 communicates with the position of the first opening 641. At this time, the flue gas enters the second chamber and then enters the first coiled pipe 55 through the first opening 641. Due to the effect of the rotating disk 62, the flue gas will not escape from the intake disk 6 through the first opening 641 or the second opening 642. At the same time, the flue gas in the first exhaust cylinder 56 directly enters the exhaust disk 7 through the third opening 721 and is then discharged by the exhaust pipe 74;

[0068] When the motor 51 starts to drive the main shaft 52 to rotate, the initial end of the first coiled pipe 55 and the end of the first exhaust cylinder 56 rotate in the first arc-shaped groove 64 and the second arc-shaped groove 73 respectively. At this time, the flue gas cannot be discharged and cannot be introduced. Due to the effect of the rotating disk 62 and the baffle 72, the flue gas will not escape from the intake disk 6 and the exhaust disk 7;

[0069] When the main shaft 52 rotates 180 degrees, the initial end of the first coiled pipe 55 rotates to the position of the second opening 642. At this time, the flue gas will enter the first coiled pipe 55 through the second opening 642, and the end of the first exhaust cylinder 56 always communicates with the third opening 721. Thus, the exhaust can be continuously carried out. In this way, through the rotating disk 62 and the baffle 72, while realizing the circulation of the flue gas, the escape of the flue gas is avoided;

[0070] Furthermore, after the filter cartridge 65 is used for a long time, particles will inevitably adhere to the surface of the filter cartridge 65 and cause blockage. In order to prevent impurities from blocking the filter cartridge 65, such as Figure 8 、 Figure 11As shown in the figure, a rotating groove 653 is provided inside the fixed sleeve 68. An outer ring of the mounting sleeve 651 is integrally designed with a slider 652. The slider 652 is located on one side of the rotating groove 653. A return spring 654 is fixedly installed on the other side of the slider 652. The other end of the return spring 654 is fixedly connected to the other end of the rotating groove 653. When the filter cartridge 65 is subjected to an external force, it will rotate, and the slider 652 presses the return spring 654. When the external force is removed, the filter cartridge 65 will reset under the action of the return spring 654. At the moment of this reset, the slider 652 has a certain impact on the fixed sleeve 68, and this impact will cause the filter cartridge 65 to vibrate, thereby achieving the effect of cleaning impurities;

[0071] A connecting sleeve 66 is fixedly installed on the main shaft 52. The connecting sleeve 66 is located inside the second chamber. A swing rod 67 is fixedly installed on the connecting sleeve 66. At the same time, a stop block (not shown in the figure) is fixedly installed on the outer surface of the filter cartridge 65. In this embodiment, the swing rod 67 is made of a flexible material. In the initial state, the top end of the swing rod 67 is in contact with the stop block. When the main shaft 52 rotates driven by the motor 51, the swing rod 67 will rotate and toggle the stop block, and the rotation of the stop block drives the filter cartridge 65 to rotate synchronously. The slider 652 presses the return spring 654. As the main shaft 52 rotates continuously, the slider 652 will continuously press the return spring 654, and at the same time, the swing rod 67 gradually deforms. When it rotates to a certain angle, the swing rod 67 passes over the stop block. At this time, the filter cartridge 65 is no longer subjected to an external force, and the return spring 654 resets under its own elastic force, driving the slider 652 and the filter cartridge 65 to reset. Due to the elastic action of the return spring 654, the slider 652 has an impact effect on the inner wall of the rotating groove 653, and thus the filter cartridge 65 will vibrate to vibrate and clean the impurities adhering to the filter cartridge 65, avoiding blockage of the filter cartridge 65;

[0072] When the main shaft 52 rotates 180 degrees, since the interval between the filter cartridges 65 is less than 180 degrees, after the swing rod 67 rotates 180 degrees following the main shaft 52, it will reach the position on the other side of another group of filter cartridges 65. When the main shaft 52 does not rotate 180 degrees, it will contact the stop block on another group of filter cartridges 65 and exert a force on it to facilitate its cleaning, and finally the swing rod 67 will reach one side of another group of filter cartridges 65;

[0073] In summary, the above device further defines the structures of the intake disk 6 and the exhaust disk 7, avoiding the entry of flue gas into the inner cavity of the thickened layer 4 without affecting the flue gas flow. A filter cartridge 65 is provided in the intake disk 6 to filter the flue gas when the flue gas enters the first coil pipe 55. At the same time, a return spring 654 and a swing rod 67 are also provided to clean the filter cartridge 65 while the main shaft 52 rotates, avoiding blockage of the filter cartridge 65.

[0074] Embodiment 3: In the above embodiment, by improving the structures of the intake disk 6 and the exhaust disk 7, the flue gas can flow smoothly and be filtered. However, despite this, a small amount of impurities will still enter the first coil 55;

[0075] To avoid this problem, taking Figure 12 as the perspective, a collection cylinder 8 is threadedly installed at the top of the first coil 55. The collection cylinder 8 includes a cylinder body 81 threadedly connected to the first coil 55. The interior of the cylinder body 81 is hollow, and an arc-shaped opening 84 is provided in the direction of the first coil 55. The flue gas and impurities can enter the cylinder body 81 through the arc-shaped opening 84. A sphere 82 is provided at the arc-shaped opening 84. One end of the sphere 82 located inside the cylinder body 81 is fixedly connected to an auxiliary spring 83, and the other end of the auxiliary spring 83 is fixedly connected to the top of the cylinder body 81;

[0076] In this embodiment, the elastic force of the auxiliary spring 83 is less than the gravity of the sphere 82. In the initial state, as Figure 12 shown, at this time the first coil 55 is located in the cavity. Due to the gravity effect, the sphere 82 freely falls. At this time, the sphere 82 blocks the arc-shaped opening 84, and the flue gas and impurities cannot enter or escape from the cylinder body 81. When the main shaft 52 drives the first coil 55 to rotate, the collection cylinder 8 also rotates 180 degrees synchronously. Due to the gravity effect, the sphere 82 moves downward, and the auxiliary spring 83 is compressed by the sphere 82. At this time, the arc-shaped opening 84 is in an open state. When the flue gas and impurities pass through the collection cylinder 8, they will enter the interior of the cylinder body 81, and the impurities themselves have a certain gravity, so the impurities will enter the interior of the cylinder body 81. When the main shaft 52 rotates back, the collection cylinder 8 rotates synchronously, and after rotation, due to gravity, the collection cylinder 8 returns to the initial closed state, and the impurities cannot fall out of the cylinder body 81;

[0077] It should be noted that in this embodiment, the pipelines at the upper end of the first coil 55 are arranged alternately in an inclined and horizontal manner. The section close to the collection cylinder 8 is inclined, and the pipeline section where the collection cylinder 8 is located is horizontal. The purpose is to enable the impurities to flow faster through the inclined pipeline to reach the horizontal section and then smoothly enter the collection cylinder 8;

[0078] To facilitate the cleaning of the collection cylinder 8, referring to Figure 3 , a maintenance opening corresponding to the number and position of the collection cylinder 8 is opened at the top of the thickened layer 4. A maintenance plug is threadedly installed at the maintenance opening. When it is necessary to clean the collection cylinder 8, the staff can, when the furnace body 2 is not working, use tools to unscrew the maintenance plug, and then manually unscrew the collection cylinder 8 for cleaning.

[0079] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
