Abstract
Description
Technical Field
[0001] This application relates to the field of feeding technology, and more specifically, to a tailings feeding device. Background Technology
[0002] In the process of producing cement using tailings, the tailings feeding device is a key piece of equipment for material conveying. Most common tailings feeding devices on the market adopt an impeller structure, which uses the rotation of the impeller to achieve quantitative conveying of tailings from the silo to subsequent equipment.
[0003] Because tailings contain hard mineral particles, they continuously rub against the impeller in the feeding device, causing the impeller surface to wear rapidly. This results in thinner, rougher blades, and even chipped or broken blades. This significantly weakens the impeller's ability to scoop and transport tailings, leading to unstable feed rates and severely impacting the accuracy and stability of subsequent production processes. Therefore, it is necessary to replace excessively worn impellers periodically.
[0004] However, the existing tailings feeding device's structural design often makes the impeller closely and complexly connected to other components of the device. Removing the impeller from the casing requires a lot of time and manpower to disassemble numerous related components. The entire replacement process is cumbersome and lengthy, greatly increasing the equipment's downtime and seriously affecting production efficiency. Summary of the Invention
[0005] The purpose of this application is to provide a tailings feeding device that can solve the technical problem that existing tailings feeding devices have a lot of manpower and time to disassemble many related components when removing the impeller from the housing due to the close and complex connection between the impeller and other components, resulting in a complicated replacement process, long downtime, and serious impact on production efficiency.
[0006] This application provides a tailings feeding device, including a housing. The top of the housing has an inlet, the bottom of the housing has an outlet, and the front side of the housing has a mounting hole. A mounting plate adapted to the mounting hole is provided in the mounting hole. An impeller is provided inside the housing, and one side of the impeller is rotatably inserted into the mounting plate. A plug-in assembly for plugging into the impeller is rotatably provided inside the housing. The housing is provided with a drive motor for driving the plug-in assembly to rotate and a locking assembly for locking the mounting plate in the mounting hole. When the plug-in assembly rotates, it drives the impeller to rotate.
[0007] Furthermore, the plug-in assembly includes a plug-in rod and a rotating shaft fixed to one end of the plug-in rod. The rotating shaft is rotatably connected to the housing. The end of the rotating shaft away from the plug-in rod extends outside the housing and is connected to the output shaft of the drive motor. The impeller is provided with a plug-in groove that matches the plug-in rod. The plug-in rod is inserted into the plug-in groove. The cross-section of the plug-in rod is polygonal.
[0008] Furthermore, a connecting post is fixedly provided on the side of the impeller near the mounting plate, and a connecting groove adapted to the connecting post is provided on the mounting plate, with the connecting post inserted into the connecting groove.
[0009] Furthermore, multiple ball bearings are movably embedded at equal intervals on the periphery of the connecting column, and the ball bearings are in rolling connection with the connecting groove.
[0010] Furthermore, two locking components are provided, symmetrically arranged. Each locking component includes a connecting lug, a locking bolt, and a retaining plate. The connecting lug is fixed to the housing and has a threaded hole adapted to the locking bolt. The retaining plate has a through hole adapted to the locking bolt. The locking bolt passes through the through hole and the threaded hole. The locking bolt is threadedly connected to the connecting lug, and the retaining plate abuts against the mounting plate.
[0011] Furthermore, a handle is fixed to the outer side of the mounting plate.

[0027] like Figure 1-3 As shown, this application provides a tailings feeding device, including a housing 1. The top of the housing 1 has an inlet 11, and the bottom of the housing 1 has an outlet 12. The front side of the housing 1 has a mounting hole 13, and a mounting plate 2 adapted to the mounting hole 13 is provided inside the mounting hole 13. An impeller 3 is provided inside the housing 1, and one side of the impeller 3 is rotatably inserted into the mounting plate 2. An insertion assembly 4 for inserting into the impeller 3 is rotatably disposed inside the housing 1. The housing 1 is provided with a drive motor 5 for driving the insertion assembly 4 to rotate and a locking assembly 6 for locking the mounting plate 2 into the mounting hole 13. When the insertion assembly 4 rotates, it drives the impeller 3 to rotate. In use, the drive motor 5 drives the insertion assembly 4 to rotate, and the insertion assembly 4 drives the impeller 3 to rotate. Tailings are fed through the inlet 11 at the top of the housing 1. As the impeller 3 rotates inside the housing 1, its blades continuously scoop up the tailings from near the inlet 11 and transport them to the outlet 12. Finally, the tailings are discharged from the outlet 12 at the bottom of the housing 1, thus realizing the tailings feeding process. In this application, the impeller 3 is rotatably inserted into the mounting plate 2 on one side, and the impeller 3 is inserted into the insertion component 4. The locking component 6 controls the fixed state of the mounting plate 2 in the mounting hole 13. When replacing the impeller 3, it is only necessary to operate the locking component 6 to loosen the mounting plate 2, and then remove the mounting plate 2 and replace the impeller 3. Compared with the prior art, the impeller 3 is easy to disassemble and assemble, effectively simplifying the impeller 3 replacement process, reducing equipment downtime, and improving production efficiency.
[0028] like Figure 2 and Figure 3As shown, the plug-in assembly 4 includes a plug-in rod 41 and a rotating shaft 42 fixed to one end of the plug-in rod 41. The rotating shaft 42 is rotatably connected to the housing 1. The end of the rotating shaft 42 away from the plug-in rod 41 extends outside the housing 1 and is connected to the output shaft of the drive motor 5. The impeller 3 is provided with a plug-in groove 31 that is adapted to the plug-in rod 41. The plug-in rod 41 is inserted into the plug-in groove 31. The cross-section of the plug-in rod 41 is polygonal. The cross-section of the plug-in rod 41 can be triangular, quadrilateral, pentagonal, etc. In this embodiment, the cross-section of the plug-in rod 41 is hexagonal, which avoids the relative rotation that may occur when the traditional circular plug-in rod 41 transmits torque. The polygonal plug-in rod 41 and the corresponding polygonal plug-in groove 31 fit tightly together. When the drive motor 5 drives the rotating shaft 42 to rotate, it can ensure that the impeller 3 rotates stably.
[0029] like Figure 2 and Figure 3 As shown, a connecting post 32 is fixedly provided on the side of the impeller 3 near the mounting plate 2. The mounting plate 2 is provided with a connecting groove 21 that is adapted to the connecting post 32. The connecting post 32 is inserted into the connecting groove 21. The design of the connecting groove 21 provides stable support for the connecting post 32. When the impeller 3 rotates, the connecting post 32 rotates in the connecting groove 21 to prevent the impeller 3 from shifting. The impeller 3 cooperates with the connecting groove 21 on the mounting plate 2 through the connecting post 32. When installing the impeller 3, it is only necessary to accurately insert the connecting post 32 into the connecting groove 21 to quickly achieve the positioning of the impeller 3 and the mounting plate 2, simplifying the installation process and improving installation efficiency.
[0030] like Figure 2 and Figure 3 As shown, multiple balls 7 are movably embedded at equal intervals on the periphery of the connecting column 32. The balls 7 are in rolling connection with the connecting groove 21. The design of the balls 7 effectively reduces the wear between the connecting column 32 and the connecting groove 21, effectively extends the service life of the connecting column 32 and the connecting groove 21, and reduces the frequency of equipment maintenance and replacement.
[0031] like Figure 1 and Figure 3 As shown, there are two locking components 6, symmetrically arranged. Each locking component 6 includes a connecting lug 61, a locking bolt 62, and a retaining plate 63. The connecting lug 61 is fixed to the housing 1 and has a threaded hole that matches the locking bolt 62. The retaining plate 63 has a through hole that matches the locking bolt 62. The locking bolt 62 passes through the through hole and the threaded hole and is threadedly connected to the connecting lug 61. The retaining plate 63 abuts against the mounting plate 2. During installation, simply place the retaining plate 63 on the mounting plate 2, then pass the locking bolt 62 through the through hole on the retaining plate 63 and screw it into the threaded hole of the connecting lug 61. Tightening the bolt will fix the mounting plate 2. During disassembly, simply reverse the operation to loosen the bolt and remove the mounting plate 2. The operation is simple.
[0032] like Figure 1-3 As shown, a handle 8 is fixed on the outer side of the mounting plate 2. The handle 8 provides the operator with a direct and convenient point of force application, making it easy for the operator to put the mounting plate 2 into the mounting hole 13 or remove it from the mounting hole 13.
[0033] like Figure 2 and Figure 3 As shown, a first sealing ring 9 is provided at the connection between the mounting plate 2 and the housing 1, and a second sealing ring 10 is provided at the connection between the rotating shaft 42 and the housing 1. During the operation of the tailings feeding device, the first sealing ring 9 can effectively prevent tailings from leaking out from the connection between the mounting plate 2 and the housing 1, while the second sealing ring 10 can prevent tailings from leaking along the gap between the rotating shaft 42 and the housing 1, thus avoiding material waste, maintaining a clean working environment, and reducing pollution to surrounding equipment and the environment.
[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
