Description

Technical Field

[0001] The present application relates to the technical field of metal smelting, and in particular to a mixing device for metal particle raw materials. Background Art

[0002] Metal smelting is the process of heating metal ore or scrap to above its melting point, melting it and separating the metals. The smelted metal is then formed into fixed ingots within a smelting furnace. This ingot is then further processed, such as metalworking, to form metal products. Metal raw materials are typically granular, and a single metal is melted to produce a single metal product. However, alloys are now widely used due to their shared advantages. Alloy smelting involves mixing multiple metals in appropriate proportions and simultaneously melting them into alloy ingots for further processing.

[0003] At present, due to the high energy consumption of the smelting furnace and the long smelting time, in order to reduce energy consumption, the melting chamber of the smelting furnace is larger and more metal raw materials can be smelted at a time. Therefore, when mixing the alloy metals before smelting, conventional drum mixers are used, which require multiple mixing operations to meet the smelting amount. Moreover, the mixers are usually fixed. After the mixing is completed, the mixed materials need to be discharged again and transferred to the smelting furnace, which is more complicated to operate. Therefore, large open tanks are currently used to mix multiple metal raw materials. Its structure is shown in the attached manual. Figure 1-2 As shown, the top side is open. After the different metal granular raw materials are poured into the trough, they are currently mixed manually using tools such as shovels. However, metal raw materials are heavier than non-metallic raw materials, so manual mixing is physically demanding and cannot guarantee that the different raw materials are fully mixed. This leads to uneven dispersion of the different metals in the alloy metal body formed by subsequent melting, and inconsistent performance of the further processed alloy products. Summary of the Invention

[0004] In response to the above-mentioned problems, the present application aims to provide a mixing device for metal particle raw materials, which can mechanically mix the metal raw materials poured into the trough through a driving mechanism, thereby solving the current problem of large physical burden during manual mixing, as well as uneven mixing caused by the increased physical burden.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a mixing device for metal particle raw materials, comprising a trough body for containing a variety of metal particle raw materials, characterized in that: a discharge port is opened on one side of the trough body, and a driving mechanism for driving the metal particle raw materials to be mechanically mixed is arranged on the trough body, and a secondary mixing mechanism for driving the metal particle raw materials to be mixed again is also arranged at the discharge port.

[0006] Preferably, the driving mechanism includes a driving impeller arranged at the center of the trough body, and the driving impeller has a plurality of picking plates.

[0007] Preferably, a material storage trough is provided on the bottom surface of the trough body located below the driving impeller.

[0008] Preferably, the bottom surfaces of the tank bodies on both sides of the storage tank are arranged to be inclined toward the storage tank.

[0009] Preferably, the secondary mixing mechanism is a mixing impeller provided on the tank body outside the discharge port.

[0010] The beneficial effect of the present application is that a driving mechanism is provided on the trough body to drive the metal particle raw materials to be mechanically mixed. The driving mechanism can be used to mechanically mix the metal raw materials poured into the trough body, thereby solving the current problem of large physical burden during manual mixing, as well as the problem of uneven mixing caused by the increased physical burden.

[0011] The secondary mixing mechanism provided at the discharge port can perform secondary mixing on the raw materials, which can further improve the mixing effect of the raw materials and the consistency of the quality of the final alloy product. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Refer to the attached Figures 1 to 7 The mixing device of a metal particle raw material shown in FIG. 1 includes a tank body 1 for containing a plurality of metal particle raw materials, such as Figure 1-2 As shown, the top side is open. After pouring different metal particle raw materials into the tank body 1, the materials are tumbled and mixed manually using tools such as shovels to achieve the mixing operation of different metal particle raw materials. In order to solve the problem of excessive physical burden and insufficient mixing of different raw materials in manual mixing, which leads to inconsistent performance of the final alloy product, Figure 3 As shown, the present application provides a driving mechanism on the trough body 1 for driving the metal particle raw materials to be mechanically mixed. The driving mechanism can be used to mechanically mix the metal raw materials poured into the trough body 1, thereby solving the current problem of large physical burden during manual mixing, as well as the problem of uneven mixing caused by the increased physical burden.

[0021] The tank body 1 is provided with a discharge port 1a on one side, which is used to fill the raw materials into the smelting furnace after the mixing is completed and the tank body 1 is hoisted as a whole. Figure 6 As shown, a detachable baffle (not shown in the figure) is provided at the discharge port 1a to prevent leakage of raw materials during the mixing process.

[0022] To further improve the mixing effect, Figure 6 As shown, a secondary mixing mechanism is also provided at the discharge port 1a to remix the metal granular raw materials. As the raw materials mixed by the driving mechanism within the trough 1 are discharged through the discharge port 1a, they are released from the trough 1 in a freely dispersed state. In this state, the secondary mixing mechanism remixes the raw materials, further improving the mixing effect of the raw materials and the consistency of the quality of the final alloy product.

[0023] Specifically, such as Figure 3 As shown, the driving mechanism includes a driving impeller 2 arranged at the center of the tank body 1, and the driving impeller 2 has a plurality of picking plates 21. The driving impeller 2 is driven to rotate by a driving motor (not shown) externally connected to the side wall of the tank body 1, and the picking plates 21 are as shown in FIG. Figure 3 As shown, it is preferably an arc-shaped structure. During the rotation process, the picking plate 21 can pick up the raw materials poured into the trough body 1 and flip it to the other side of the trough body 1, and the raw materials on this side can be manually pushed to the picking plate 21 again to be picked up and flipped again, thereby realizing the continuous mixing operation of the raw materials.

[0024] The bottom surface of the flat structure of the tank body 1 is difficult to smoothly pick up and turn the raw materials for mixing. Therefore, in order to solve this problem, Figure 4 As shown, a material storage trough 1b is provided on the bottom of the tank body 1, below the driving impeller 2. Multiple raw materials are poured into this trough. Because the trough 1b is lower than the bottom of the tank body 1, the material pick plate 21 rotates to pick up a sufficient amount of raw materials for mixing. The mixed raw materials on the other side are then pushed back into the trough 1b by the operator and picked up again by the material pick plate 21 for mixing.

[0025] In order to further reduce the manual labor burden of pushing the mixed raw materials into the storage tank 1b again, as shown in FIG. Figure 5 As shown, the inner bottom surfaces of the trough body 1 on both sides of the storage trough 1b are arranged to be inclined toward the storage trough 1b. The raw materials poured into the trough body 1 can slide along the inclined surface into the storage trough 1b and be picked up by the picking plate 21 for mixing. The mixed raw materials on the other side also slide along the inclined structure of the inner bottom surface of the trough body 1 into the storage trough 1b and are picked up again for mixing. Furthermore, manual labor can assist in pushing the raw materials into the storage trough 1b. Compared with the current method of directly picking up and mixing the raw materials with a shovel, and pushing the materials on the inner bottom surface of the flat structure of the trough body 1, the physical burden of manual operation can be greatly reduced.

[0026] In order to realize the operation of mixing the mixed raw materials again after pouring them into the smelting furnace, Figure 6-7 As shown, the secondary mixing mechanism is a mixing impeller 3 provided on the tank body 1 outside the discharge port 1a. Its structure is the same as that of the driving impeller 2, or the peripheral surface of the driving impeller is provided with a rough surface structure. When the raw materials leave the tank body 1 and are discharged through the discharge port 1a, the falling force of the raw materials drives the mixing impeller 3 to rotate (or the mixing impeller 3 is actively rotated by the motor). During the rotation process, the freely dispersed raw materials are driven to mix again by the blades or the rough surface structure, thereby further improving the mixing effect of the raw materials.

[0027] The principle of this application is as follows: a driving impeller 2 with a material picking plate 21 is set in the center of the tank body 1, and a material storage trough 1b is opened on the bottom surface of the tank body 1 below the driving impeller 2. At the same time, the inner bottom surface of the tank body 1 is set to an inclined structure facing the material storage trough 1b, and a mixing impeller 3 is also set outside the discharge port 1a. During the mixing operation, various raw materials are poured into the material storage trough 1b. Because the material storage trough 1b is lower than the inner bottom surface of the tank body 1, the material picking plate 21 can pick up a sufficient amount of raw materials during the rotation process to flip and mix them, while the mixed raw materials on the other side slide along the inclined structure of the inner bottom surface of the tank body 1 into the material storage trough 1b and are picked up and mixed again. After a certain period of time, the raw materials can be fully mixed. In the process of discharging the raw materials into the smelting furnace after the trough body is lifted, the falling force of the raw materials drives the mixing impeller 3 to rotate (or the mixing impeller 3 is actively rotated by the motor). During the rotation process, the raw materials in the freely dispersed state are driven to be mixed again through its blades or rough surface structure, thereby further improving the mixing effect of the raw materials.

[0028] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
