[0021] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the following will further illustrate the embodiments of the utility model in combination with specific embodiments and with reference to the drawings.

[0022] It should be noted that all the expressions of "first" and "second" in the embodiments of the utility model are used to distinguish two same name but different entities or different parameters. It can be seen that "first" and "second" are only for the convenience of expression, and should not be understood as a limitation of the embodiments of the utility model. The subsequent embodiments will not be described one by one.

[0023] According to one aspect of the present application, the embodiment of the present application provides a disc feeding device, as shown in the drawings, which can include: Figure 1

[0024] The disc feeding machine comprises a disc 1.

[0025] The connecting part is fixed at one end of the disc 1.

[0026] The shaft coupling 3 is connected to the other end of the connecting part.

[0027] A plurality of rake rods 4 are arranged on the shaft coupling 3.

[0028] The scheme provided by the present application can effectively clean and agitate the "dead zone" caused by factors such as the structure of the material bin, the structure of the disc 1, and the characteristics of the material during the movement of the rake rod 4. Thus, the defects of the existing disc feeding machine, such as the inability to turn, loosen, and partially accumulate the material when the material enters the disc 1, can be overcome.

[0029] In some embodiments, the disc feeding machine is used as a basic device, and the disc 1 is a key component for carrying and conveying the material. The connecting part is fixed at one end of the disc 1 to play a role in connection and power transmission. The other end is connected to the shaft coupling 3 to realize further transmission of power. The plurality of rake rods 4 are arranged on the shaft coupling 3 to directly act on the material and complete the turning and loosening tasks. That is, during the operation of the disc feeding machine, the spline shaft sleeve 2 welded on the disc feeder is driven to move, the shaft coupling 3 connected to the spline shaft sleeve 2 through the fixed pin 5 rotates, and the rake rod 4 welded on the shaft coupling 3 rotates, thereby continuously turning and loosening the leaching residue in the operation of the rake rod 4, making the leaching residue more evenly distributed on the entire working surface of the disc feeder. Subsequently, under the action of the slag scraping plate, centrifugal force, and the like, the leaching residue is evenly distributed on the belt conveyor 6 and then transferred to the roasting furnace. The rake rod 4 can also effectively clean and agitate the "dead zone" caused by factors such as the structure of the material bin, the structure of the disc 1, and the characteristics of the material during the movement of the rake rod 4.

[0030] In this way, the size of the existing material bin and disc feeding machine can be maintained, and the rake device can be driven to operate by the operation of the disc feeding machine, thereby realizing stable discharging. Meanwhile, the device has the advantages of low cost, quick disassembly and assembly, convenient maintenance, and convenient use, which can not only ensure stable and uniform discharging of the leaching residue, reduce product quality accidents in the process of production, but also reduce the labor intensity of the post personnel and the use risk.

[0031] In some embodiments, the connecting part is a spline shaft sleeve 2, which comprises a spline shaft and a spline sleeve, and the spline sleeve is welded at the center of the disc 1.

[0032] ​Specifically, as shown in Figure 2 The connecting part adopts a spline shaft sleeve 2 structure, which is composed of a spline shaft and a spline sleeve. The spline sleeve is welded at the center of the disc 1, which can ensure the stability of the connection and prevent the connecting part from loosening or displacement during high-speed rotation of the disc 1, effectively transmitting power and maintaining stable operation of the device.

[0033] In some embodiments, the shaft coupling 3 is detachably connected to the spline shaft.

[0034] In some embodiments, the shaft coupling 3 is connected to the spline shaft through a fixed pin 5.

[0035] Specifically, the shaft coupling 3 and the spline shaft are detachably connected, specifically through a fixed pin 5. This connection method has significant advantages. During equipment installation, debugging, and later maintenance, the shaft coupling 3 can be easily and quickly disassembled and assembled, reducing the difficulty and time cost of equipment maintenance. When a component fails or needs to be replaced, it can be quickly operated, reducing equipment downtime and improving production efficiency.

[0036] In some embodiments, multiple rake bars 4 are arranged at a preset distance vertically.

[0037] In some embodiments, multiple rake bars 4 are vertically welded in the southeast, southwest, and northwest directions of the shaft coupling 3.

[0038] Specifically, multiple rake bars 4 are arranged at a preset distance vertically. In the preferred embodiment of the present application, the vertical distance is 20 cm. At the same time, the rake bars 4 are vertically welded in the southeast, southwest, and northwest directions of the shaft coupling 3. Such a layout design allows the rake bars 4 to turn with the shaft coupling 3, enabling them to turn and loosen the material in all directions, ensuring that the material is evenly distributed on the disc 1 and avoiding local accumulation or uneven distribution of the material.

[0039] In some embodiments, the material of the rake bar 4 is wear-resistant steel.

[0040] Specifically, the rake bar 4 is made of wear-resistant steel. In actual work, the rake bar 4 needs to frequently contact with the material and is subjected to friction and impact from the material. Wear-resistant steel has excellent wear resistance and strength, which can effectively resist wear from the material, prolong the service life of the rake bar 4, reduce the frequency of equipment maintenance and replacement of parts, and reduce production costs.

[0041] In some embodiments, the length of the rake bar 4 is 30-50 cm.

[0042] In some embodiments, the ratio of the diameter of the disc 1 to the length of the rake bar 4 is 3:1-5:1.

[0043] Specifically, in order to ensure the optimization of the raking effect, the length of the raking rod 4 is accurately set between 30-50 cm. This length range is verified through a large number of experiments and practices, which can ensure that the raking rod 4 fully acts on the material to achieve effective turning and loosening of the material, and will not affect the overall operation stability of the device due to being too long. At the same time, the diameter of the disc 1 and the length of the raking rod 4 are controlled in a ratio of 3:1-5:1, so that the raking rod 4 can fully play a role in the working range of the disc 1 to achieve uniform distribution of the material, and further improve the working efficiency of the device.

[0044] In some embodiments, the surface of the raking rod 4 is provided with anti-skid lines.

[0045] Specifically, the anti-skid lines arranged on the surface of the raking rod 4 can significantly increase the friction between the raking rod 4 and the material. In the process of turning and loosening the material, the anti-skid lines effectively prevent the material from slipping on the raking rod 4, so that the raking rod 4 can more effectively push and turn the material, improve the raking effect, and ensure that the material is uniformly distributed on the disc 1.

[0046] When installing the raking device of the disc feeder of the utility model, first, the spline shaft sleeve 2 is accurately welded at the center position of the feeder. The welding process needs to strictly control the welding process parameters to ensure the welding quality and ensure the firm and reliable connection between the spline shaft sleeve 2 and the feeder, so as to avoid loosening in the subsequent operation process. Then, the raking rod 4 made of wear-resistant steel is welded in the southeast, northwest, and northeast directions of the shaft coupling 3 with an interval of 20 cm and a vertical angle of 90 degrees. The perpendicularity and spacing accuracy of the raking rod 4 need to be ensured during the welding process, so that the raking rod 4 can uniformly act on the material during rotation and achieve good raking effect. Finally, the shaft coupling 3 with the raking rod 4 welded is connected with the spline shaft sleeve 2 through the fixed pin 5. When installing the fixed pin 5, it is necessary to ensure that it is accurately inserted into the corresponding pin hole and is properly fastened, so as to ensure the close connection between the shaft coupling 3 and the spline shaft sleeve 2 and effectively transmit power. After the installation of the above-mentioned components is completed, the entire raking device is assembled with the disc feeder to ensure the cooperation accuracy and installation firmness between the components.

[0047] When the disc feeder starts to operate, the disc 1 drives the spline shaft sleeve 2 welded on the feeder to rotate synchronously. Since the spline shaft sleeve 2 and the shaft coupling 3 are tightly connected through the fixed pin 5, the shaft coupling 3 rotates, and in turn drives the raking rod 4 welded on the shaft coupling 3 to rotate at high speed.

[0048] During the rotation of the rake bars 4, the leaching residues are turned and loosened by the rake bars 4. The rotation of the rake bars 4 causes the material to continuously roll on the disc 1, breaks the adhesion between the materials, and makes the materials more evenly distributed on the entire working surface of the disc 1. With the rotation of the disc 1, the leaching residues treated by the rake bars are evenly distributed on the belt conveyor 6 under the combined action of the scraper and the centrifugal force, and then are smoothly transferred to the roasting furnace to enter the subsequent production process. During the operation, the rake bars 4 can also effectively clean and agitate the "dead zones" where the materials are stagnant due to factors such as the structure of the material bin, the structure of the disc 1, and the characteristics of the materials. Through continuous turning and agitation, the flowability of the materials is maintained, the materials are prevented from accumulating to form dead materials in the disc 1 or the material bin, and the materials can continuously and smoothly flow in the disc feeder, achieving stable and uniform discharge.

[0049] The scheme provided by the utility model can effectively clean and agitate the "dead zones" where the materials are stagnant due to factors such as the structure of the material bin, the structure of the disc, and the characteristics of the materials during the movement of the rake bars. Thus, the defects that the existing disc feeder cannot turn the materials, loosen the materials, and the materials may be locally accumulated when entering the disc and the material bin are overcome.
