Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coking coal preparation lines, and particularly relates to a hopper structure with an anti-blocking hopper device. Background Art
[0002] In the prior art, the plugging hopper device used in the coking coal preparation line is generally a pressure-sensitive plugging hopper device. However, since the easily blocked positions of each material discharging hopper in the coking coal preparation line are different, therefore, after the coal is piled up, the pressure-sensitive plugging hopper device will not act, resulting in the material blocking the discharging port. After being blocked, it is very difficult for the operator to clean the material, and it takes a long time for the staff to clean it, which is time-consuming and laborious. Moreover, due to the disadvantages of inconvenient installation and replacement, low sensitivity, easy damage, and high price of the pressure-sensitive plugging hopper device, therefore, there is an urgent need for a plugging hopper device that is easy to install, highly sensitive, and not easily damaged. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a hopper structure with an anti-blocking hopper device for the deficiencies and defects in the prior art. The anti-blocking hopper device of this hopper is not only simpler and more convenient to install and use, but also more stable and reliable during use. It can quickly respond when the material level in the hopper rises to the device monitoring point, thus avoiding a large amount of material accumulation in the discharging hopper and ensuring the smooth operation of the discharging hopper. At the same time, the anti-blocking hopper device of this hopper can be applied to the anti-blocking material monitoring of discharging hoppers for any medium conveyed by belt conveyors and pipe belt conveyors, which is more practical.
[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A hopper structure with an anti-blocking hopper device, which includes a discharging hopper 9 for discharging materials and an anti-blocking hopper device 8 for preventing the discharging hopper 9 from being blocked. It is characterized in that: the anti-blocking hopper device 8 includes a protective cover 2, a proximity switch installation hole 5 is opened in the middle of the protective cover 2, a proximity switch 1 is installed in the inner cavity of the proximity switch installation hole 5, and a pull rod 3 is fixedly connected above the protective cover 2. One end of the pull rod 3 is connected with a steel wire rope 4, and a metal hose 7 is installed at the connection end of the proximity switch 1, and the connection wire of the proximity switch 1 is arranged in the metal hose 7.
[0005] Further, a proximity switch installation nut 6 for installing and fixing the proximity switch 1 is arranged on the protective cover 2.
[0006] Further, a lifting device is installed at the top end of the steel wire rope 4.
[0007] Further, the inner diameter of the proximity switch installation hole 5 is larger than the outer diameter of the proximity switch 1.
[0008] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: This anti-blocking hopper device is not only simpler and more convenient to install and use, but also more stable and reliable during use. It can quickly respond when the material level in the hopper rises to the monitoring point of the device, thus avoiding a large accumulation of materials in the feeding hopper, ensuring the smooth operation of the feeding hopper. At the same time, this anti-blocking hopper device can be applied to the anti-blocking material monitoring of the feeding hoppers of belt conveyors and pipe belt conveyors for transporting any medium, which is more practical.

[0014] Refer to Figures 1 - 3 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a feeding hopper 9 for feeding and an anti-blocking hopper device 8 for preventing the feeding hopper 9 from being blocked. The characteristics are that the anti-blocking hopper device 8 includes a protective cover 2. A proximity switch mounting hole 5 is provided in the middle of the protective cover 2. A proximity switch 1 is installed in the inner cavity of the proximity switch mounting hole 5. A pull rod 3 is fixedly connected above the protective cover 2. One end of the pull rod 3 is connected with a steel wire rope 4. A metal hose 7 is installed at the connection end of the proximity switch 1, and the connection wire of the proximity switch 1 is arranged inside the metal hose 7.
[0015] More specifically, a proximity switch mounting nut 6 for installing and fixing the proximity switch 1 is provided on the protective cover 2.
[0016] More specifically, a lifting device is installed at the top end of the steel wire rope 4. The relative height between the anti-blocking hopper device 8 and the feeding hopper 9 is controlled through the lifting device.
[0017] More specifically, the inner diameter of the proximity switch mounting hole 5 is larger than the outer diameter of the proximity switch 1. This facilitates the rapid installation of the proximity switch 1 on the protective cover 2 by the staff, thereby increasing the installation efficiency of the staff.
[0018] The working principle of the present utility model: During use, the staff can install the proximity switch 1 in the proximity switch mounting hole 5 of the protective cover 2 and fix the proximity switch 1 on the protective cover 2 through the proximity switch mounting nut 6. Then, the steel wire rope 4 is hung on the pull rod 3, and the anti-blocking hopper device 8 is hung at the corresponding position of the feed hopper 9 as required. The proximity switch 1 is used to detect the feeding state of the feed hopper 9. When the feed hopper 9 is blocked, when the material blockage rises to a specified position, the proximity switch 1 will detect the material and promptly disconnect the control circuit of the belt conveyor to stop the belt conveyor from running, effectively avoiding the increase of blocked materials and facilitating the staff to clean the feed hopper 9 in time, and preventing further blockage and leakage of the material. Among them, the metal hose 7 can protect the connecting wire of the proximity switch 1 and extend the service life of the proximity switch 1.
[0019] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model, as long as they do not depart from the spirit and scope of the technical solution of the present utility model, shall be covered by the scope of the claims of the present utility model.
