Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production technology, and in particular to a smelting furnace for aluminum alloy production. Background Technology

[0002] Aluminum alloys are alloys based on aluminum with the addition of certain amounts of other alloying elements, and are one of the lightweight metal materials. The processing of aluminum alloys typically includes the following key stages: smelting, casting, extrusion, and heat treatment. In the smelting process, a smelting furnace is used to melt raw materials such as bauxite at high temperatures.

[0003] Chinese patent CN210773397U discloses an energy-saving smelting furnace for aluminum alloy production, including a fixed base. Fixed plates are fixed to both sides of the top outer wall of the fixed base, and a rotating shaft is rotatably connected to the opposite outer wall of each of the two fixed plates via bearings. A fixed frame is fixed between the opposite outer walls of the two rotating shafts, and a smelting furnace body is installed on the inner wall of the fixed frame. A drain pipe is installed on one outer wall of the smelting furnace body. The inner wall of the fixed frame has evenly distributed fixing teeth. Threaded holes are opened on both outer walls of the fixed frame, and fastening bolts are threaded to the inner walls of both threaded holes. A first motor is fixed to one outer wall of one of the fixed plates, and one end of the output shaft of the first motor is bolted to the rotating shaft.

[0004] In the aforementioned smelting furnace, the tilting of the furnace is directly driven by the output shaft of the first motor during material pouring. The tilt is maintained by the self-locking mechanism of the first motor. However, the first motor needs to withstand additional axial force, and this force after self-locking significantly impacts its lifespan and increases maintenance costs. Furthermore, in small-scale factory production, the transfer of smelted materials becomes a crucial step due to the lack of a complete production line. Traditional methods typically rely on manual operation by workers. Specifically, workers must push a trolley to the smelting furnace and then tilt it to pour the material into a container on the trolley. During this process, workers must constantly ensure the trolley is positioned accurately to catch the material. However, material spillage during pouring is highly likely, increasing operational complexity and significantly raising the safety risks of the work environment. Utility Model Content

[0005] The main purpose of this utility model is to provide a smelting furnace for aluminum alloy production, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a smelting furnace for aluminum alloy production, comprising:

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By using the self-locking property of the worm gear to fix the tilt angle of the smelting furnace through the set material discharge mechanism, the output shaft of the motor will not be subjected to force, thereby improving the service life of the motor.

[0022] 2. With the positioning plate and locking mechanism, workers only need to push the trolley onto the positioning plate and lock it using the locking mechanism. Workers can stay away from the dumping area, avoiding direct contact with high-temperature materials and the risk of splashing, which greatly improves operational safety. Moreover, once the trolley is locked, it will not shift when dumping materials, ensuring that the transfer container can accurately catch the materials. Attached Figure Description

[0031] Please see Figure 1-4 This utility model provides a smelting furnace for aluminum alloy production, comprising:

[0032] Base 1;

[0033] Two brackets 2 are fixedly installed on both sides of the upper side wall of the base 1. A bearing seat 21 is fixedly connected to the upper side wall of the bracket 2, and a rotating shaft 22 is provided inside the bearing seat 21.

[0034] The smelting furnace 3 is fixedly installed between the two rotating shafts 22;

[0035] Positioning plate 4 is fixedly installed on the front side wall of base 1, and side plates 41 are fixedly connected to both sides of the front side wall of positioning plate 4.

[0036] A trolley 5, on which a transfer container 51 is fixedly connected;

[0037] Locking mechanism 6 is installed on positioning plate 4 and is used to lock trolley 5.

[0038] The material discharge mechanism 7 is mounted on one of the supports 2 and is used to tilt the smelting furnace 3 to discharge materials.

[0039] With the above structure, the output shaft of motor 73 is not subjected to force during material discharge, which can prevent motor 73 from being damaged due to force when it is self-locking, thus improving its service life. In addition, through the positioning plate 4 and the locking mechanism 6, workers can stay away from the dumping area during material discharge, avoiding direct contact with high-temperature materials and the risk of splashing, which greatly improves operational safety.

[0040] The locking mechanism 6 includes a locking groove 61, a cavity 62, a lifting plate 63, a locking block 64, and a spring 65. Two symmetrically distributed locking grooves 61 are provided on the front side wall of the positioning plate 4. A cavity 62 is provided on one side wall of the positioning plate 4. A lifting plate 63 is slidably provided in the cavity 62. A locking block 64 is fixedly connected to the lower side wall of the lifting plate 63 at the position corresponding to the locking groove 61. The locking block 64 is located between the locking groove 61 and the cavity 62. Two springs 65 are provided between the upper side wall of the lifting plate 63 and the upper side wall of the cavity 62.

[0041] With the above structure, the trolley 5 can be fixed on the positioning plate 4 to ensure the accuracy of pouring materials.

[0042] The material discharge mechanism 7 includes a fixed plate 71, a worm gear 72, a motor 73, and a worm wheel 74. Two fixed plates 71 are fixedly connected to one side wall of the bracket 2 away from the smelting furnace 3. A worm gear 72 is rotatably connected between the two fixed plates 71. A motor 73 is installed on the front side wall of one of the fixed plates 71. The output shaft of the motor 73 is fixedly connected to one end of the worm gear 72. A worm wheel 74 that meshes with the worm gear 72 is fixedly connected to one end of the rotating shaft 22 away from the smelting furnace 3.

[0043] With the above structure, the smelting furnace 3 can be tilted to pour materials, and the self-locking property of the worm gear 74 and worm 72 is used to fix the smelting furnace 3 after it is tilted.

[0044] Two insert blocks 52 that are adapted to the locking groove 61 are fixedly connected to the rear side wall of the trolley 5. The upper side wall of the insert block 52 is provided with a positioning groove 53. After the locking block 64 is inserted into the positioning groove 53, the insert block 52 can be fixed in the locking groove 61, thereby locking the trolley 5 and preventing it from shifting.

[0045] One side wall of the lifting plate 63 extends out of the groove 62 to facilitate lifting the lifting plate 63.

[0046] The two side plates 41 are provided with guide grooves 411 on the side wall that are close to each other. The two side walls of the trolley 5 are fixedly connected with guide blocks 54 that are adapted to the guide grooves 411. The guide grooves 411 on the side plates 41 can help position the trolley 5 and improve the fixing effect of the trolley 5, so that it will not deviate when pouring materials.

[0047] Among them, a support plate 8 is fixedly connected to one side wall of the positioning plate 4 and below the groove cavity 62. A limiting support rod 81 is rotatably provided on the upper side wall of the support plate 8. The limiting support rod 81 is used to limit the lifting plate 63.

[0048] It should be noted that this utility model is a smelting furnace for aluminum alloy production. After smelting, the lifting plate 63 is raised, causing the locking block 64 to move upward. Then, the limiting support rod 81 is rotated to support the lifting plate 63, limiting the lifting plate 63 and preventing it from being pushed back by the spring 65. Then, the guide blocks 54 on both sides of the trolley 5 are inserted into the guide grooves 411, pushing the trolley 5 so that the insert block 52 on the trolley 5 is inserted into the locking groove 61 on the positioning plate 4. Then, the limiting support rod 81 is reversed to release the limitation on the lifting plate 63. The lifting plate 63 will be pushed down by the spring 65, causing the locking block 64 to be inserted into the positioning groove 53 on the insert block 52, thus pushing the trolley 5. Cart 5 is secured, and then the worker moves away from the dumping area and starts motor 73. The output shaft of motor 73 drives worm gear 72 to rotate. When worm gear 72 rotates, it can cause worm wheel 74 to rotate one of the rotating shafts 22. The rotation of rotating shaft 22 drives smelting furnace 3 and the other rotating shaft 22 to rotate, causing smelting furnace 3 to tilt and dump materials. During the dumping process, cart 5 is locked so that it will not fall, ensuring that transfer container 51 can accurately catch materials. After dumping, lift plate 63 is lifted up so that locking block 64 is disengaged from positioning groove 53. Then, limit support rod 81 is used to limit lift plate 63, and cart 5 can be pulled out.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
