Description

Technical Field

[0001] The invention relates to the technical field of slag cleaning, and in particular to an online slag cleaning device for an aluminum alloy solution holding furnace. Background Art

[0002] In the production process of casting aluminum alloy smelting, the aluminum alloy liquid needs to be diverted into the holding furnace for storage in order to facilitate the storage and rapid shipment of the aluminum alloy liquid. In the storage link, since the aluminum alloy liquid will be mixed with some impurities when entering the holding furnace, slag will be generated around the furnace wall over time, eventually causing erosion and agglomeration of the holding furnace. The traditional holding furnace is designed with a slag cleaning port for slag cleaning.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] The current online slag cleaning device needs to use an iron rod or the like to knock the slag inside the insulation furnace during slag cleaning so that it can fall to the bottom of the furnace and then be discharged from the slag cleaning port. During this process, due to the cylindrical structure of the furnace body, the higher position of the inner wall of the furnace body is more difficult to clean during cleaning.

[0005] Therefore, it is necessary to provide an online slag cleaning device for an aluminum alloy solution holding furnace to solve the above technical problems. Summary of the invention

[0006] The technical problem to be solved by the present invention is that during cleaning, the higher positions on the inner wall of the furnace body are more difficult to clean. In view of the above-mentioned defects of the prior art, an online slag cleaning device for an aluminum alloy solution insulation furnace is provided.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: an online slag cleaning device for an aluminum alloy solution holding furnace, comprising a holding furnace, the top of which is rotatably connected to a main gear, the bottom of which is provided with a spiral scraper for cleaning slag, the bottom of which is fixedly connected to a reinforcing column, and the reinforcing column and the spiral scraper are fixedly connected.

[0008] By adopting the above technical scheme, the rotating movement of the spiral scraper can efficiently scrape off the slag on the inner wall of the insulation furnace, avoiding the inefficiency and high labor intensity of traditional manual slag cleaning, improving the slag cleaning efficiency, and strengthening the connection effect of the column to ensure the stability and reliability of the spiral scraper during the rotation process, so that the slag cleaning operation can be carried out continuously and stably, reducing the downtime caused by equipment failure.

[0009] It is further provided that a motor is fixedly connected to one side of the insulation furnace, and a first gear is fixedly connected to an output end of the motor.

[0010] By adopting the above technical solution, the introduction of the motor improves the degree of automation of slag cleaning operations, reduces the intensity and frequency of manual operations, and improves work efficiency. The direct connection between the first gear and the motor ensures the efficiency and stability of power transmission and reduces the possibility of energy loss and mechanical failure.

[0011] It is further provided that one side of the first gear is meshed with an input gear of a gearbox, and an output gear of the gearbox is meshed with a main gear.

[0012] By adopting the above technical solution, the introduction of the gearbox makes the entire transmission system more flexible and controllable. By adjusting the transmission ratio of the gearbox, the speed of the main gear can be easily changed to adapt to the slag cleaning requirements under different working conditions.

[0013] It is further provided that a slag cleaning port is provided at the bottom of the heat preservation furnace, and a slag cleaning door is rotatably connected to one side of the slag cleaning port.

[0014] By adopting the above technical solution, the opening of the slag cleaning port improves the convenience of the slag cleaning operation. Through the slag cleaning port, the scraped slag can be directly discharged out of the furnace without the need for additional operations or equipment, saving time and labor costs.

[0015] It is further provided that the edge of the spiral scraper is in a triangular structure, and the guiding surface of the spiral scraper is inclined toward the central axis direction of the insulation furnace.

[0016] By adopting the above technical solution, the edge of the triangular structure improves the scraping efficiency of the spiral scraper, so that the slag removal operation can be completed faster and more thoroughly, which not only saves time but also reduces the potential impact on the quality of the aluminum alloy solution caused by residual slag.

[0017] It is further configured that a plurality of the reinforcing columns are provided, and the plurality of the reinforcing columns have different lengths.

[0018] By adopting the above technical solution, the provision of multiple reinforcement columns significantly improves the durability and reliability of the spiral scraper. During the slag cleaning operation, the spiral scraper needs to withstand various forces and pressures, and the supporting effect of multiple reinforcement columns enables the spiral scraper to better resist these external forces, thereby extending the service life of the equipment.

[0019] It is further provided that a furnace cover is rotatably connected to one side of the top of the insulation furnace, and a motor compartment for accommodating a motor is provided on one side of the insulation furnace.

[0020] By adopting the above technical solution, the rotating connection of the furnace cover improves the operating convenience and insulation effect of the insulation furnace. The operator can open or close the furnace cover at any time as needed. The airtightness of the furnace cover helps to reduce heat loss and improve the energy efficiency of the insulation furnace.

[0021] It is further provided that the heat preservation furnace is provided in a cylindrical structure, and a lock buckle for locking the furnace cover is provided on one side of the heat preservation furnace.

[0022] By adopting the above technical solution, the cylindrical structure of the insulation furnace improves the uniformity of heat distribution and the insulation effect, which is conducive to the high-quality treatment of aluminum alloy solution. The setting of the lock significantly improves the safety and airtightness of the insulation furnace.

[0023] It is further provided that an observation window is provided on the slag cleaning door, a locking rod is provided on one side of the observation window, and a slope for facilitating slag discharge is provided at the bottom of the slag cleaning port.

[0024] By adopting the above technical solution, the operator can directly understand the slag situation inside the insulation furnace through the observation window, avoiding unnecessary slag cleaning operations, saving time and labor costs. The setting of the locking rod enhances the safety and stability of the slag cleaning operation. By locking the slag cleaning door, the operator can ensure that the slag cleaning door always remains closed during the slag cleaning operation, avoiding safety accidents caused by accidental opening of the slag cleaning door.

[0025] It is further provided that a hook is fixedly connected to the top of the furnace cover, and ear hooks are fixedly connected to both sides of the insulation furnace.

[0026] By adopting the above technical solution, through the cooperation of the lifting equipment and the hook, the operator can easily open and close the furnace cover without the need for laborious or risky manual operation, which saves time and labor costs and reduces safety risks during operation.

[0027] Compared with the related art, the online slag cleaning device for aluminum alloy liquid holding furnace provided by the present invention has the following beneficial effects:

[0028] The present invention provides an online slag cleaning device for an aluminum alloy solution holding furnace. By arranging a spiral scraper, efficient removal of slag on the inner wall of the holding furnace is achieved. After the motor is started, the first gear is meshed with the input gear of the gearbox, and then the speed change action of the gearbox causes the output gear to rotate at an appropriate speed, and finally drives the main gear to rotate, thereby ensuring that the spiral scraper can rotate in the holding furnace at a stable and appropriate speed, thereby effectively scraping off the slag on the furnace wall. The edge of the spiral scraper is in a triangular structure, so that the spiral scraper can scrape off the slag on the furnace wall more deeply during the rotation process, thereby improving the efficiency and thoroughness of slag cleaning. The guiding surface of the spiral scraper is inclined toward the central axis of the holding furnace, so that the scraped slag can be smoothly guided to the bottom of the holding furnace under the rotation of the spiral scraper and the action of gravity, thereby facilitating subsequent slag removal operations.

[0029] The present invention provides an online slag cleaning device for an aluminum alloy solution holding furnace. The device adopts an inclined surface so that in the process of digging out the slag, the slag can smoothly slide out of the slag cleaning port of the holding furnace with the help of the inclination angle of the inclined surface, thereby improving the efficiency and smoothness of slag discharge, avoiding the accumulation and blockage of the slag at the slag cleaning port, thereby saving the time and energy of the operator. The inclined surface ensures that the slag can accurately fall into a recycling vehicle. During the slag cleaning operation, the operator does not need additional adjustment or intervention, and the slag can naturally slide along the inclined surface and directly fall into the recycling vehicle, which not only improves the continuity of the operation, but also reduces the scattering and waste of slag, which is beneficial to environmental protection and resource recycling.

[0041] like Figure 5 As shown, a motor 5 is fixedly connected to one side of the holding furnace 1, and a first gear 6 is fixedly connected to the output end of the motor 5. The fixed connection between the motor 5 and the first gear 6 also facilitates maintenance and repair of the entire slag cleaning device.

[0042] like Figure 5 As shown, one side of the first gear 6 is meshed with the input gear 8 of the gearbox 7, and the output gear 9 of the gearbox 7 is meshed with the main gear 2. The gearbox 7 also has a torque amplification function. When the output torque of the motor 5 is small, the amplification effect of the gearbox 7 can provide sufficient torque for the main gear 2 to drive the spiral scraper 3 to rotate, thereby ensuring the smooth progress of the slag cleaning operation.

[0043] like Figure 1 and Figure 6 As shown, a slag cleaning port 10 is provided at the bottom of the holding furnace 1, and a slag cleaning door 11 is rotatably connected to one side of the slag cleaning port 10. The rotatable connection design of the slag cleaning door 11 makes the slag cleaning operation more flexible and controllable. The operator can open or close the slag cleaning door 11 at any time according to actual needs to ensure the smooth progress of the slag cleaning operation and the normal operation of the holding furnace 1.

[0044] like Figure 2 and Figure 3 As shown, the edge 31 of the spiral scraper 3 is in a triangular structure, and the guide surface 32 of the spiral scraper 3 is inclined toward the central axis of the insulation furnace 1. The inclined design of the guide surface 32 ensures the smooth discharge of the slag. Under the rotation of the spiral scraper 3, the slag is continuously scraped off and moves toward the center of the furnace bottom along the guide surface 32, and is finally discharged out of the furnace through the slag cleaning port 10.

[0045] like Figure 2 As shown, a plurality of reinforcing columns 4 are provided, and the lengths of the plurality of reinforcing columns 4 are different. The plurality of reinforcing columns 4 and the different lengths also reserve space for slag cleaning, providing convenience for subsequent slag cleaning maintenance.

[0046] like Figure 1 and Figure 4As shown, a furnace cover 12 is rotatably connected to one side of the top of the insulation furnace 1, and a motor compartment 13 for accommodating the motor 5 is provided on one side of the insulation furnace 1.

The cylindrical structure and the lock buckle 14 also take into account the ease of use and maintainability of the equipment. The cylindrical structure makes the cleaning and maintenance of the furnace cavity 21 and the furnace wall 22 inside the insulation furnace 1 more convenient, and the simplicity and ease of use of the lock buckle 14 also makes it easier and faster for the operator to lock and unlock the furnace cover 12.

[0048] like Figure 1 and Figure 4 As shown, a hook 18 is fixedly connected to the top of the furnace cover 12, and ear hooks 19 are fixedly connected to both sides of the insulation furnace 1. The provision of the ear hooks 19 makes the handling and movement of the insulation furnace 1 easier and safer, improves the efficiency of the handling operation, and ensures the integrity and safety of the insulation furnace 1.

[0049] The implementation principle of the present invention is as follows: first, the motor 5 is started, and its output end drives the first gear 6 to rotate, and the first gear 6 is meshed with the input gear 8 of the gearbox 7. Through the speed change action of the gearbox 7, the output gear 9 rotates at an appropriate speed and meshes with the main gear 2, thereby driving the main gear 2 to rotate on the top of the insulation furnace 1.

[0050] The bottom of the main gear 2 is fixedly connected to the spiral scraper 3 through a reinforcing column 4. Therefore, when the main gear 2 rotates, the spiral scraper 3 also rotates. The edge 31 of the spiral scraper 3 is in a triangular structure, which can more effectively scrape off the slag on the furnace wall. The guiding surface 32 of the spiral scraper 3 is inclined toward the central axis of the insulation furnace 1, so that the scraped slag can be guided to the bottom of the insulation furnace 1 under the rotation of the spiral scraper 3 and the action of gravity.

[0051] During the slag cleaning process, the slag is continuously scraped off by the spiral scraper 3 and accumulated at the bottom of the holding furnace 1. When slag discharge is required, the operator can open the slag cleaning door 11 and shovel it out. The bottom of the slag cleaning port 10 is provided with a slope 17 to facilitate the smooth discharge of slag.

[0052] In addition, a furnace cover 12 is rotatably connected to one side of the top of the insulation furnace 1, which is convenient for maintenance and inspection of the interior of the insulation furnace 1, so that the spiral scraper 3 can be lifted upward when it needs to be cleaned. The motor 5 is installed in the motor compartment 13 to protect the motor 5 from the influence of the harsh environment. The furnace cover 12 can be locked by a lock 14 to ensure that the furnace cover 12 will not loosen.

[0053] In order to facilitate the observation of the slag cleaning process and the discharge of slag, an observation window 15 is provided on the slag cleaning door 11. The slag cleaning door 11 is also equipped with a locking rod 16 to ensure that the slag cleaning door 11 can be firmly closed during the slag cleaning process, and the internal slag cleaning situation can be observed through the observation window 15.

Under the guidance of the slope 17, the slag can be discharged from the insulation furnace 1 more smoothly, avoiding the accumulation and blockage of the slag, thereby improving the usability and maintainability of the entire slag cleaning device.

[0057] The implementation principle of the present invention is as follows: first, the inclined surface 17 enables the slag to slide out smoothly when it is dug out, and then fall into the recycling vehicle.

[0058] The advantages of this technical solution in practical applications include but are not limited to the following:

[0059] 1. The triangular structure enables the spiral scraper to scrape the slag on the furnace wall more deeply during the rotation process, thus improving the efficiency and thoroughness of slag removal;

[0060] 2. The slag can slide out of the slag removal port of the holding furnace smoothly with the help of the inclination angle of the slope, which improves the efficiency and smoothness of slag discharge.
