Description

Technical Field

[0001] This utility model relates to the field of coal conveying equipment technology, and in particular to a compartmentalized coal bunker. Background Technology

[0002] To meet the requirements of electricity market regulation and ensure the fundamental interests of power plants, production typically employs either low-quality coal or a mixture of high-quality and low-quality coal during off-peak or off-peak periods, while high-quality coal is used during peak periods. Based on this, existing coal bunkers have been improved by creating two internal compartments with partitions to facilitate the flexible switching between high-quality and low-quality coal, thereby reducing costs and improving economic efficiency. However, this compartmentalization presents a problem during the discharge process. When both low-quality and high-quality coal are discharged simultaneously, if one compartment is blocked while the other is unobstructed, coal can still be discharged from the bottom. This makes it impossible to determine whether both compartments are functioning correctly, causing significant inconvenience and negatively impacting the power plant's production efficiency. Therefore, there is an urgent need for a compartmentalized coal bunker system capable of monitoring the discharge status within the bunker. Utility Model Content

[0003] The purpose of this utility model is to provide a compartmentalized coal bunker that can monitor the material feeding status of the two cavities after compartmentalization, preventing one cavity from being blocked and the other open when material is fed into the two cavities of the coal bunker at the same time, thus ensuring production efficiency.

[0004] The present invention adopts the following technical solution:

[0005] A coal bunker with compartments includes a main body, the interior of which is divided into two cavities by a partition. Each cavity has vertically aligned slide rails on its exterior. A pull rod is slidably mounted within each slide rail, and a measuring weight is connected to the pull rod via a rope. The measuring weight is located within the corresponding cavity. A guide wheel is rotatably mounted on each slide rail, and the guide wheel is connected to a first distance measuring device mounted on the slide rail. During operation, the rope passes through the guide wheel and connects to the measuring weight. As the amount of coal in each cavity decreases, the measuring weight falls, and the rope drives the guide wheel to rotate.

[0006] Preferably, the measuring weight is a cone-shaped structure with the tip pointing downwards.

[0007] Preferably, a take-up roller is rotatably mounted at the bottom of the slide rail, and a take-up rope connected to the pull rod is mounted on the take-up roller; the take-up roller is connected to a second rangefinder.

[0008] Preferably, the take-up roller is driven by a motor mounted on the slide rail, and a ratchet is mounted on the motor shaft. One end of the take-up roller is elastically provided with ratchet teeth that mesh with the ratchet. When it is necessary to wind up the take-up rope on the take-up roller, the motor rotates, and at this time the ratchet meshes with the ratchet teeth.

[0009] Preferably, the slide rail has an L-shaped structure, and two guide wheels are provided on the horizontal section at its top, with the first rangefinder connected to each guide wheel.

[0010] Preferably, a sealing plate is provided on the slide rail above the guide wheel.

[0011] Preferably, the longitudinal section of the sealing plate is a triangular structure.

[0012] Preferably, both ends of the pull rod are rotatably equipped with rollers, and the inner wall of the slide rail is provided with a groove for the rollers to slide.

[0013] Preferably, the slide rail sidewall is provided with scale lines.

[0014] Preferably, the pull rod is provided with an indicator needle.

[0015] Compared with the prior art, the advantages of this utility model are: by setting up a measuring weight, the measuring weight can move down synchronously with the falling coal under the action of gravity. At this time, the pull rod will rise along the slide rail, which makes it convenient to observe the material feeding situation on site; at the same time, the rangefinder will also collect data with the rotation of the guide wheel and feed the data back to the back-end control. The back-end can judge the material feeding situation based on the data fed back by the rangefinder, effectively grasp the material feeding situation of the coal bunker. The structure is simple and the practicality is strong. Attached Figure Description

[0021] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0022] like Figures 1 to 5 As shown, the present invention provides a compartmentalized coal bunker, comprising a bunker body 1, the interior of which is divided into two cavities by a partition. Each cavity has a vertically aligned slide rail 2, and a pull rod 3 is slidably mounted within each slide rail 2. The pull rod 3 is connected to a measuring weight 4 via a rope 12. The measuring weight 4 is located within the corresponding cavity and is preferably a cone-shaped structure with its tip pointing downwards to ensure stability of its center of gravity. A guide wheel 5 is rotatably mounted on the slide rail 2, and the guide wheel 5 is connected to a first distance measuring device 6 mounted on the slide rail 2. During operation, the rope 12 connects to the measuring weight 4 via the guide wheel 5. As the coal in the corresponding cavity decreases during the unloading process, the measuring weight 4 falls, and the pull rod 3 rises along the slide rail 2, facilitating direct observation of the unloading situation on-site. Simultaneously, the rope 12 drives the guide wheel 5 to rotate, and the first distance measuring device 6 transmits relevant data to the backend, allowing backend staff to monitor the coal bunker unloading situation. When coal is added to the corresponding space inside the coal bunker body 1 after the unloading is completed, the pull rod 3 moves down, causing the measuring weight 4 to reset. After the coal is added, the pull rod 3 is released, and the measuring weight 4 moves down to contact the top surface of the coal. Subsequently, as the coal is used, the measuring weight 4 moves down and the pull rod 3 rises in sync.

[0023] Furthermore, a take-up roller 7 is rotatably mounted at the bottom of the slide rail 2, and a take-up rope 11 connected to the pull rod 3 is mounted on the take-up roller 7. A second rangefinder is connected to the take-up roller 7, and the second rangefinder is connected to the control device to cooperate with the first rangefinder 6 to improve the accuracy of data feedback. The second rangefinder is not shown in the figure. The arrangement of the take-up roller 7 facilitates the pulling of the pull rod 3 and the resetting of the measuring weight 4 by rotating the take-up roller 7. Preferably, the take-up roller 7 is driven by a motor 8 mounted on the slide rail 2. The take-up roller 7 is movably connected to the rotating shaft of the motor 8, and a ratchet 9 is mounted on the rotating shaft of the motor 8. One end of the take-up roller 7 is elastically provided with ratchet teeth 10 that mesh with the ratchet 9. When it is necessary to wind up the take-up rope 11 on the take-up roller 7, the motor 8 rotates, at which time the ratchet 9 meshes with the ratchet teeth 10. During the falling of the measured coal, the motor 8 is in a stopped state. As the measuring weight 4 falls, it drives the take-up roller 7 to rotate, releasing the take-up rope 11 on it. The pull rod 3 drives the take-up rope 11 to rise along the slide rail 2. In this utility model, the measuring weight 4 needs to have a certain weight to overcome the friction between the ratchet 9, ratchet teeth 10, guide wheel 5 and rope 12, pull rod 3 and slide rail 2, etc. At the same time, it should not be too heavy to avoid sinking too much into the coal when stationary. It is advisable that the measuring weight 4 is just in contact with the coal or slightly penetrates into the coal when stationary.

[0024] Furthermore, in this embodiment, the slide rail 2 has an L-shaped structure, with the vertical section located outside the coal bunker body 1 and the horizontal section extending towards the center of the corresponding cavity, so that the weight 4 can be measured to be located in the center of the corresponding cavity. Two guide wheels 5 are provided on the horizontal section at the top, and each guide wheel 5 is connected to a first rangefinder 6. The arrangement of multiple guide wheels 5 can not only provide guidance for the rope 12 and reduce the wear between the rope 12 and the slide rail 2, but also connect with the first rangefinder 6 to perform multi-point measurements. In conjunction with the second rangefinder, the relevant data is fed back to the background control equipment, which makes it easier for the background staff to better understand the material feeding status. Since the distance of one revolution of the guide wheel 5 and the winding roller 7 is fixed, the remaining coal in the coal bunker body 1 can also be judged based on the data fed back by the first rangefinder 6 and the second rangefinder, so as to perform timely replenishment operations. It effectively makes up for the shortcomings of the existing material level rotary switch. Although the existing material level rotary switch can detect the material level, when the material fills the area around the material level rotary switch, even if the material feeding at the bottom is normal, the material level rotary switch will not trigger an alarm. In addition, the material level rotary switch cannot measure the remaining coal.

[0025] Furthermore, in this embodiment, a sealing plate 13 is provided on the slide rail 2 above the guide wheel 5 to prevent coal from falling onto the top of the slide rail 2 during the feeding process, thus affecting the normal use of the rope 12 and the guide wheel 5. Preferably, the longitudinal section of the sealing plate 13 is a triangular structure, with the apex of the triangle facing upwards, so that the two sides of the sealing plate 13 form outwardly sloping surfaces, so as to prevent coal from accumulating on the top of the sealing plate 13 during the process of adding coal into the coal bunker body 1.

[0026] Furthermore, rollers are rotatably mounted at both ends of the pull rod 3, and grooves 14 are provided on the inner wall of the slide rail 2 for the rollers to slide. The rollers effectively reduce the resistance when the pull rod 3 moves, enabling the pull rod 3 to move smoothly up and down. In addition, a scale line is preferably provided on the side wall of the slide rail 2 located outside the coal bunker body 1. The scale line facilitates the visual observation of the remaining coal in the coal bunker based on the corresponding position of the pull rod 3. Preferably, an indicator needle 15 is provided on the pull rod 3 to further improve the convenience of data observation.

[0027] In use, this invention utilizes the falling of the measuring weight 4 to visually observe whether the coal is falling through the movement of the pull rod 3, and also allows for monitoring in the background using data feedback from the first and second rangefinders. It features a simple structure, ease of use, and strong practicality. When coal needs to be added after falling, the control motor 8 drives the winding roller 7 to rotate. As the winding rope 11 winds up, the pull rod 3 moves downward, causing the measuring weight 4 to move upward until the addition is complete and the motor 8 stops, at which point the measuring weight 4 naturally falls to the surface of the coal. Subsequently, during coal discharge, the movement of the pull rod 3 and the data feedback from the first and second rangefinders in the background can indicate whether there is any blockage in the corresponding cavity of the coal bunker body 1.
