Description

Technical Field

[0001] This application relates to the field of coal mining roadway backfilling technology, and more specifically, to a deep-well coal gangue filling system. Background Technology

[0002] A search revealed Chinese patent number CN202120568346.7, which discloses a deep-well coal gangue filling system belonging to the field of coal mining roadway backfilling technology. This system controls the amount of material falling from the material inlet by using a baffle that can be opened and closed. The inclined shaft has an inclination angle of 30°-60°. The inner wall of the casing is annularly equipped with several resistance plates to impede the speed of the material sliding down the casing. The system also includes a material thrower that throws the material transported by the conveyor to the mining face. Furthermore, the system includes an anti-blocking and unblocking device to unclog the casing and prevent blockage of the conveying device. This system enables the stable, continuous, and efficient transport of coal gangue from the surface to the underground, filling the mining face. Moreover, the coal gangue conveying system has a simple structure, low construction cost, and an anti-blocking and unblocking device, reducing material transport costs.

[0003] However, the above solution still has its drawbacks. When a blockage occurs, as the winch operates and the steel cable pulls the cross beam inside the sleeve upwards, the cross beam inevitably collides with the sleeve and the resistance plate, reducing the service life of the cross beam, sleeve, and resistance plate, and giving users a poor user experience. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a deep well coal gangue filling system, which aims to improve the problem that when blockage occurs, the crossbar inside the casing inevitably collides with the casing and resistance plate during the process of the winch working and driving the steel cable to drag the crossbar inside the casing upward, which reduces the service life of the crossbar, casing and resistance plate.

[0005] This application is implemented as follows: This application provides a deep well coal gangue filling system, including a feeding device installed on the surface of the well, a conveying device for conveying the material discharged from the feeding device to the underground conveying device, a receiving pool for receiving the material delivered by the conveying device, and a conveyor for conveying the material falling from the discharge port of the receiving pool. The feeding device includes a storage pool with a discharge port at the bottom. The material conveying device is installed inside the inclined shaft and includes a casing that runs through the inclined shaft. The system also includes a control device for controlling the amount of material falling from the discharge port. This device controls the amount of material falling from the discharge port by means of a baffle installed at the discharge port that can be opened and closed. The inclination angle of the inclined shaft is 30°-60°. The inner wall of the casing is circumferentially equipped with several resistance plates that can impede the speed of the material sliding down the casing. The system also includes a material thrower for throwing the material transported by the conveyor to the mining face. It also includes a blockage prevention and unblocking mechanism, which is used to unclog the sleeve.

[0006] In one embodiment of this application, the anti-blockage and unblocking mechanism includes a winch, a steel cable, a cross, and a guide rod. One end of the guide rod is fixed inside the receiving pool, the cross is slidably sleeved on the guide rod, one end of the steel cable is fixed on the outer wall of the cross, and the other end of the steel cable is disposed on the winch. A guide hole is provided on the resistance plate, and the guide hole and the cross are correspondingly disposed.

[0007] In one embodiment of this application, the diameter of the cross is equal to the distance between the two corresponding guide holes.

[0008] In one embodiment of this application, the cross has a groove, and the guide rod is slidably inserted into the groove.

[0009] In one embodiment of this application, a reinforcing rib is further included, which is fixed between the inner wall of the receiving pool and the guide rod.

[0010] In one embodiment of this application, the spacing between the resistance plates is less than the length of the cross, and the spacing between the lowest resistance plate and the cross is less than the length of the cross.

[0011] In one embodiment of this application, the system further includes a remote monitoring system and a remote control system, wherein the remote monitoring system is used to monitor the operation of the system; and the remote control system is used to control the operation of the system.

[0012] In one embodiment of this application, the conveyor is a telescopic belt conveyor.

[0013] The beneficial effects of this application are: the deep well coal gangue filling system obtained by the above design uses guide rods and guide holes to make the cross move along the designated guide, avoiding collision between the cross and the casing and resistance plate, improving the service life of the cross, casing and resistance plate, and bringing a better user experience.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0018] Please see Figures 1-8 This application provides a technical solution: a deep well coal gangue filling system, including a feeding device 110 installed on the well, a conveying device 120 for conveying the material discharged from the feeding device 110 to the underground, a receiving pool 130 for receiving the material delivered by the conveying device 120, and a conveyor 140 for conveying the material falling from the discharge port 192 of the receiving pool 130. The feeding device 110 includes a storage pool 194, and the bottom of the storage pool 194 is provided with a discharge port 192. The material conveying device 120 is installed inside the inclined shaft 150, and includes a casing 160 that penetrates the inclined shaft 150. The system also includes a control device 170 for controlling the material discharge amount at the discharge port 192. This device controls the material discharge amount at the discharge port 192 by means of a baffle 180 installed at the discharge port 192 that can be opened and closed. The inclination angle of the inclined shaft 150 is 30°-60°. The inner wall of the casing 160 is circumferentially equipped with several resistance plates 190 that can impede the speed of the material sliding down the casing 160. The system also includes a material thrower 191 that throws the material transported by the conveyor 140 to the mining face. The system also includes a remote monitoring system and a remote control system. The remote monitoring system is used to monitor the operation of the system. The remote control system is used to control the operation of the system. The conveyor 140 is a telescopic belt conveyor. It also includes an anti-blockage and unblocking mechanism 193, which is used to unblock the sleeve 160 and prevent blockage. The anti-blockage and unblocking mechanism 193 includes a winch 1931, a steel cable 1932, a cross 1933, and a guide rod 1935. One end of the guide rod 1935 is fixed inside the receiving pool 130. The cross 1933 is slidably sleeved on the guide rod 1935. One end of the steel cable 1932 is fixed to the outer wall of the cross 1933, and the other end of the steel cable 1932 is set on the winch 1931. A guide hole 1937 is opened on the resistance plate 190, and the guide hole 1937 and the cross 1933 are correspondingly arranged. The diameter of the cross 1933 is equal to the distance between the two corresponding guide holes 1937. The cross 1933 has a groove 1934, and the guide rod 1935 is slidably inserted into the groove 1934. It also includes a reinforcing rib 1936, which is fixed between the inner wall of the receiving pool 130 and the guide rod 1935. The setting of the reinforcing rib 1936 makes the guide rod 1935 more firmly fixed in the receiving pool 130. The distance between the resistance plates 190 is less than the length of the cross 1933, and the distance between the lowest resistance plate 190 and the cross 1933 is less than the length of the cross 1933.

[0019] Specifically, the working principle of this deep-shaft coal gangue filling system is as follows: During operation, coal gangue accumulated on the ground is used as filling material for the goaf of the mining face. The coal gangue is dumped from the ground through the inclined shaft casing 160 into the underground roadway, then transported by the telescopic conveyor 140 to the throwing machine 191. The throwing machine 191 then throws the coal gangue onto the coal face, completing the filling. This inclined feeding method is significant for existing inclined shaft coal mines. Utilizing the weight of the coal gangue and the resistance plate 190, it achieves both rapid descent and relatively controllable speed, avoiding the shortcomings of direct-feed systems. The system also has an anti-blockage and unblocking device. In case of blockage, under the control of the remote control system, the control device 170 is shut down, the feeding device 110 stops feeding, and the winch 1931 is started, dragging the receiving pool 1 via the steel cable 1932. The cross 1933 within the casing 160 moves upwards along the guide rod 1935 and guide hole 1937, preventing collisions between the cross 1933 and the casing 160 and resistance plate 190, thus clearing the casing 160. After clearing, the winch 1931 is reversed, releasing the steel cable 1932. Under its own weight, the cross 1933 moves along the guide hole 1937 onto the guide rod 1935, returning the guide rod 1935 to its initial position. Then, deep well filling can continue. This deep well coal gangue filling system uses the guide rod 1935 and guide hole 1937 to move the cross 1933 along a designated guide, preventing collisions between the cross 1933 and the casing 160 and resistance plate 190, thus improving the service life of the cross 1933, casing 160, and resistance plate 190, and providing users with a better experience.
