Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ore and slag handling equipment, and in particular to a slag transfer hopper. Background Technology
[0002] During the transfer process, slag is usually transported to the hopper by a conveyor belt. The slag first falls onto the receiving plate of the hopper, and then falls from the receiving plate onto the bottom plate.
[0003] However, existing hoppers have some problems, such as: the diameter is too small, and when the slag falls in a parabolic trajectory, it hits the hopper baffle and bottom plate at high speed, resulting in a series of problems such as baffle penetration, weld failure, and inner lining plate detachment, which seriously shortens the service life of the equipment; at the same time, the connection between the receiving plate of the hopper and other structures is welded, with zero degrees of freedom, and the vibration effect is not obvious. When the slag is too wet in rainy weather, the slag powder will stick to the receiving plate and cannot be vibrated off. If it is not cleaned for a long time, it will cause material blockage and leakage, and in severe cases, it will cause the entire production line to stop. Summary of the Invention
[0004] In order to increase the working efficiency and service life of existing hoppers, this application provides a slag transfer hopper.
[0005] This application provides a slag transfer hopper, employing the following technical solution:
[0006] A slag transfer hopper includes a support frame with a receiving plate and a bottom plate. The receiving plate is connected to the support frame via an elastic connecting assembly. The elastic connecting assembly includes a material accumulation trough on the bottom plate. The elastic connecting assembly includes a connecting seat, a spring, and a guide rod. The guide rod passes vertically through the support frame. The connecting seat is fixedly connected to the receiving plate and slidably connected to the guide rod. The spring is sleeved on the guide rod and is used to drive the connecting seat away from the support frame.
[0007] Optionally, a vibrator is provided on the back of the receiving plate.
[0008] Optionally, multiple material collection troughs are provided, and the multiple material collection troughs are arranged in parallel and spaced apart.
[0009] Optionally, a spiral scraper shaft is rotatably connected to the bracket. The axis of rotation of the spiral scraper shaft is set in the horizontal direction. A scraper is also provided on the circumferential surface of the spiral scraper shaft. The scraper is used to scrape off the slag adhering to the non-working surface of the conveyor belt.
[0010] Optionally, the bracket is slidably connected to a bearing seat in the vertical direction, the spiral scraper shaft is rotatably connected to the bearing seat, and the bearing seat is also provided with a limiting component for limiting its own sliding.
[0011] Optionally, the bracket is provided with a plurality of horizontally threaded holes spaced apart in the vertical direction, and the limiting component includes a plurality of bolts, one end of which passes through the bearing seat in the horizontal direction and is screwed into the threaded hole to limit the sliding of the bearing seat.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] This application extends the width of the hopper and adds a bottom plate buffer device. Then, the connection method between the receiving plate and other components is redesigned. The receiving plate with the vibrator installed at the rear is changed from welding and fixing at both ends to elastic fixing. This can greatly increase the vibration amplitude of the receiving plate to solve the problem of ore accumulation in rainy weather. At the same time, a double-threaded scraper shaft is added to scrape off the ore sticking to the conveyor belt in time. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0020] This application discloses a slag transfer hopper, which is installed below a belt conveyor 6. It includes a support 1, a receiving plate 2 is installed on the support 1 through an elastic connecting component 4, and a bottom plate 3 is also provided on the support 1, which is located downstream of the receiving plate 2.
[0021] The elastic connecting component 4 includes a connecting seat 43, a spring 42, and a guide rod 41. The connecting seat 43 is fixedly connected to the receiving plate 2, and the guide rod 41 is vertically inserted into the bracket 1. The connecting seat 43 is slidably connected to the guide rod 41. The spring 42 is sleeved on the guide rod 41 and is located between the connecting seat 43 and the bracket 1. When slag falls from the belt conveyor 6 onto the receiving plate 2, the elastic connecting component 4 can provide a buffering effect. At the same time, it increases the receiving plate 2's vertical and horizontal degrees of freedom. When sticky wet material falls onto the receiving plate 2, the receiving plate 2 will vibrate to disperse it, thereby solving the problem of material accumulation on the receiving plate 2.
[0022] In order to enable the receiving plate 2 to vibrate actively, a vibrator 21 is also provided on the back of the receiving plate 2. The vibrator 21 generates vibration to disperse the wet material.
[0023] After the ore slides down from the receiving plate 2, it will fall onto the bottom plate 3. The bottom plate 3 has multiple material accumulation troughs 31, which are arranged in parallel and spaced apart. After the bottom plate 3 is improved, the first batch of wet slag enters the hopper and falls onto the gradient material accumulation troughs 31, forming a dynamic buffer layer structure. The impact energy of the subsequent slag is dissipated in multiple stages through the buffer layer, effectively avoiding plastic deformation and puncture of the bottom plate 3 due to impact load.
[0024] Finally, this application also considers that wet material may adhere to the non-working surface of the belt conveyor 6. As the belt rotates, the bracket 1 is also provided with a function for scraping off this part of the wet material. A spiral scraper shaft 52 is attached to the bracket 1, and the rotation axis of the spiral scraper shaft 52 is set in the horizontal direction. A scraper 54 is provided on the spiral scraper shaft 52, and the scraper 54 is close to the non-working surface of the belt conveyor 6. Thus, the operation of the belt conveyor 6 is used to scrape off the adhered wet material.
[0025] To facilitate adjustment of the scraping effect, the distance between the scraper 54 and the conveyor belt can be adjusted according to the thickness of the residual wet ore on the conveyor belt. The bracket 1 has multiple horizontal threaded holes 11 spaced apart along the vertical direction. Bearing seats 51 are installed on the threaded holes 11 by bolts 53. The spiral scraper shaft 52 is rotatably connected to the bearing seats 51. By installing the bearing seats 51 in the threaded holes 11 at different heights, the height of the bearing seats 51 and the spiral scraper shaft 52 can be changed, thereby adapting to different thicknesses of wet material and achieving a better scraping effect.
[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
