Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal scrap smelting technology, and specifically to a non-ferrous metal scrap smelting apparatus. Background Technology

[0002] Non-ferrous metal scrap refers to metal products that have lost their original function but still have recycling value during industrial production or consumption. It mainly includes scrap materials of non-ferrous metals such as copper, aluminum, lead, and zinc. After recycling, these non-ferrous metal scraps need to be processed. Common recycling methods include smelting. Non-ferrous metal scrap smelting is a process of heating and melting scrap non-ferrous metal products or industrial waste, removing impurities, and adjusting the composition.

[0003] Before smelting non-ferrous metal scrap, it is necessary to crush, screen, and dry the scrap. After processing, the scrap is put into the smelting furnace and heated to above the melting point, turning it into a liquid.

[0004] In the traditional non-ferrous metal scrap smelting process, a large amount of heat is emitted from the furnace opening. If it is not effectively recovered, it will result in significant energy waste. At the same time, cold materials need to be heated for a long time after being put in to reach their melting point, and the whole process consumes a lot of energy. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a non-ferrous metal scrap smelting device, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a non-ferrous metal scrap smelting apparatus, comprising: A U-shaped base is provided, with a smelting furnace arranged inside the U-shaped base. Two symmetrically distributed rotating shafts are arranged outside the smelting furnace. A servo motor for driving the smelting furnace to rotate is installed outside the U-shaped base. A heating element is provided at the bottom of the smelting furnace. The pretreatment mechanism includes a preheating cylinder disposed above a melting furnace. Two symmetrically distributed side plates are fixedly connected to the outside of the preheating cylinder. A cylinder is installed at the bottom of one of the side plates. A partition is fixedly connected to the inner wall of the preheating cylinder. A slot extending to the outside of the preheating cylinder is opened at the top of the partition. A pull-out baffle is provided inside the slot. The stirring mechanism includes a drive motor installed on the outside of the preheating cylinder, the output shaft of the drive motor is fixedly connected to a transmission rod, and a flap is provided on the outside of the transmission rod.

[0007] Preferably, a fixed seat is fixedly connected to the outside of the U-shaped seat, and the cylinder is installed on the outside of the fixed seat.

[0008] Preferably, a limiting rod is fixedly connected to the bottom of one of the side plates, a limiting sleeve is fixedly connected to the outside of the U-shaped seat, and the bottom end of the limiting rod passes through the limiting sleeve and is slidably connected to the inner wall of the limiting sleeve.

[0009] Preferably, a feed hopper is provided at the top of the preheating cylinder, and the discharge port of the feed hopper is connected to the interior of the preheating cylinder.

[0010] Preferably, a slider is fixedly connected to the inner wall of the slot, and two symmetrically distributed grooves are opened on the outer side of the baffle, with the slider slidably connected to the inner wall of the groove.

[0011] Preferably, the preheating cylinder has a cavity inside, and the inner wall of the preheating cylinder has connecting holes that are evenly distributed near the bottom, with the other side of the connecting holes communicating with the inside of the cavity.

[0012] Preferably, a connecting rod is fixedly connected to the outside of the transmission rod, and the flap is fixedly connected at an angle to the end of the connecting rod away from the transmission rod.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, by setting up a pretreatment mechanism, allows the preheating cylinder to shield the furnace opening of the smelting furnace when smelting non-ferrous metal scrap. This effectively slows down the heat loss inside the smelting furnace and utilizes the temperature at the furnace opening to preheat the non-ferrous metal scrap inside the preheating cylinder. After preheating, the non-ferrous metal scrap can be heated to its melting point by the smelting furnace more quickly. This not only avoids the waste of heat at the furnace opening but also preheats the non-ferrous metal, reducing energy consumption during subsequent heating.

[0014] 2. By setting up a stirring mechanism, when the residual heat from the furnace opening of the smelting furnace preheats the non-ferrous metal scrap in the preheating cylinder, the drive motor drives the flap through the transmission rod to stir the non-ferrous metal scrap inside the preheating cylinder. In addition, with the heat transfer through the connecting hole and the cavity, the non-ferrous metal scrap inside the preheating cylinder can be preheated evenly, which facilitates the subsequent smelting operation.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments. Example 1:

[0020] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a non-ferrous metal scrap smelting apparatus, comprising: U-shaped base 1, with a smelting furnace 2 for smelting non-ferrous metal scrap on the inner side of the U-shaped base 1, two symmetrically distributed rotating shafts 7 on the outer side of the smelting furnace 2, a servo motor 4 for driving the smelting furnace 2 to rotate on the outer side of the U-shaped base 1, and a heating element 3 at the bottom of the smelting furnace 2. The output shaft of the servo motor 4 is connected to one of the rotating shafts 7, so that the servo motor 4 and the rotating shaft 7 can drive the melting furnace 2 to rotate, which facilitates unloading.

[0021] The pretreatment mechanism 5 includes a preheating cylinder 57 disposed above the melting furnace 2. Two symmetrically distributed side plates 53 are fixedly connected to the outside of the preheating cylinder 57. A cylinder 52 is installed at the bottom of one of the side plates 53. A partition 59 is fixedly connected to the inner wall of the preheating cylinder 57. A slot 510 extending to the outside of the preheating cylinder 57 is opened at the top of the partition 59. A pull-out baffle 54 is provided inside the slot 510.

[0022] When the smelting furnace 2 smelts non-ferrous metal scrap, the heat generated is discharged through the furnace opening and heats the preheating cylinder 57, thereby preheating the non-ferrous metal scrap inside the preheating cylinder 57. After the liquefied non-ferrous metal scrap liquid inside the smelting furnace 2 is discharged, the preheated non-ferrous metal scrap is put into the smelting furnace 2.

[0023] Specifically, a fixed seat 51 is fixedly connected to the outside of the U-shaped seat 1, and the cylinder 52 is installed on the outside of the fixed seat 51.

[0024] The cylinder 52 is fixed from the bottom by the fixed seat 51 to ensure the stability of the cylinder 52 during operation. The cylinder 52 can drive the preheating cylinder 57 to move upward, which facilitates the rotation of the smelting furnace 2.

[0025] Specifically, a limiting rod 56 is fixedly connected to the bottom of one side plate 53, and a limiting sleeve 55 is fixedly connected to the outside of the U-shaped seat 1. The bottom end of the limiting rod 56 passes through the limiting sleeve 55 and is slidably connected to the inner wall of the limiting sleeve 55.

[0026] The movement trajectory of the preheating cylinder 57 can be limited by the limiting rod 56 and the limiting sleeve 55, ensuring the stability of the preheating cylinder 57 when it moves up and down.

[0027] Specifically, a feed hopper 58 is provided at the top of the preheating cylinder 57, and the outlet of the feed hopper 58 is connected to the interior of the preheating cylinder 57.

[0028] The feed hopper 58 facilitates the conveying of non-ferrous metal scrap into the preheating cylinder 57 for preheating.

[0029] Specifically, a slider 511 is fixedly connected to the inner wall of the slot 510, and two symmetrically distributed grooves 512 are opened on the outer side of the baffle 54, with the slider 511 slidably connected to the inner wall of the groove 512.

[0030] The movement trajectory of the baffle 54 can be limited by the slider 511 and the groove 512, so that the baffle 54 can be inserted into the slot 510 or pulled out from the slot 510, so that the preheated non-ferrous metal scrap inside the preheating cylinder 57 can directly enter the melting furnace 2. Example 2:

[0031] Reference Figure 1-5This is the second embodiment of the present invention, which differs from the first embodiment in that: The stirring mechanism 6 includes a drive motor 61 installed on the outside of the preheating cylinder 57. The output shaft of the drive motor 61 is fixedly connected to a transmission rod 65, and a flap 62 is provided on the outside of the transmission rod 65.

[0032] The drive motor 61 can drive the external flap 62 to rotate through the transmission rod 65, which agitates the non-ferrous metal waste inside the preheating cylinder 57, thus facilitating its uniform preheating.

[0033] Specifically, a cavity 63 is provided inside the preheating cylinder 57, and a connecting hole 64 with equal spacing is provided on the lower part of the inner wall of the preheating cylinder 57. The other side of the connecting hole 64 is connected to the inside of the cavity 63.

[0034] The connection hole 64 facilitates the entry of heat into the cavity 63, and the cavity 63 facilitates the heating of the non-ferrous metal scrap inside the preheating cylinder 57.

[0035] Specifically, a connecting rod 66 is fixedly connected to the outside of the transmission rod 65, and a flap 62 is fixedly connected at an angle to the end of the connecting rod 66 away from the transmission rod 65.

[0036] The connecting rod 66 can connect the flap 62 and the transmission rod 65. When the transmission rod 65 rotates, the flap 62 can rotate accordingly to agitate the non-ferrous metal waste.

[0037] The remaining structure is the same as that in Example 1.

[0038] The workflow of this utility model is as follows: When smelting non-ferrous metal scrap, smelting furnace 2 heats the non-ferrous metal scrap to reach its melting point temperature; The next batch of non-ferrous metal scrap to be smelted is fed into the preheating cylinder 57 through the feeding hopper 58. The heat generated when the smelting furnace 2 is working enters the connecting hole 64 through the furnace opening, and then enters the cavity 63 through the connecting hole 64. It is then transferred to the preheating cylinder 57 through the cavity 63 to preheat the non-ferrous metal scrap inside the preheating cylinder 57. The drive motor 61 drives the flap 62 to rotate through the transmission rod 65. The rotation of the flap 62 agitates the non-ferrous metal scrap inside the preheating cylinder 57. After the non-ferrous metal scrap in the smelting furnace 2 is smelted, the cylinder 52 pushes the preheating cylinder 57 to move upward until the smelting furnace 2 can be flipped. At this time, the servo motor 4 can drive the smelting furnace 2 to flip through the rotating shaft 7, pouring out the molten liquid inside. After pouring out, the servo motor 4 rotates in the opposite direction to reset the smelting furnace 2. The cylinder 52 retracts, causing the preheating cylinder 57 to move downwards until it contacts the top of the smelting furnace 2. At this time, the baffle 54 is pulled to remove the restriction on the non-ferrous metal scrap inside the preheating cylinder 57. The preheated non-ferrous metal scrap can enter the smelting furnace 2 below through the slot 510 to smelt the preheated non-ferrous metal scrap. At the same time, the next batch of non-ferrous metal scrap is transported into the preheating cylinder 57.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
