Description
Technical Field
[0001] The present invention relates to the field of conveying equipment, and in particular to a small underground chamber slag discharge device. Background Art
[0002] An underground chamber is a man-made underground space, typically used for construction of underground tunnels, garages, shopping malls, storage rooms, and more. It fully utilizes underground space, conserves surface land resources, and provides a safer and more comfortable environment. Excavation requires consideration of various factors, including geological conditions, hydrological conditions, and construction techniques, and requires specialized equipment. Furthermore, excavation typically generates large amounts of excavated soil, requiring a desludging device to effectively handle this material.
[0003] Currently, belt conveyors are the primary method for conveying excavated soil. During underground chamber excavation, large, often damp, lumps of excavated soil are often found. Furthermore, existing excavation methods often place this soil directly onto belt conveyors, which can lead to large chunks of soil rolling off during oblique conveying. If the soil contains a high level of moisture, water can accumulate on the belt surface after extended periods of transport, causing the soil to slip along the belt. This compromises conveying efficiency and poses a safety hazard. Summary of the Invention
[0004] In order to overcome the above-mentioned shortcomings of the current method of directly using a belt conveyor to transport slag, the technical problem to be solved by the present invention is to provide a small underground chamber slag discharge device that can crush the slag and evaporate moisture.
[0005] The technical solution adopted by the present invention to solve its technical problem is: The heat dissipation device of claim 1, wherein the upper end of the heat dissipation box and the lower end of the heat dissipation box are connected to each other to form a heat dissipation device, wherein the heat dissipation device is connected to the heat dissipation device to generate a heat dissipation device for the heat dissipation device.
[0006] Furthermore, an air outlet is provided at one end of the top of the drying box away from the feed hopper, protective grilles are provided on both the inner and outer sides of the air outlet, and a fan is installed inside the air outlet.
[0007] Furthermore, the heat-conducting inclined plate is made of metal, and multiple electric heating rods are embedded inside it. A controller is provided at the bottom. The controller is electrically connected to each electric heating rod through a cable. A humidity sensor is provided in the drying box or crushing box, and the humidity sensor is electrically connected to the controller.
[0008] Furthermore, the driving mechanism includes a hydraulic cylinder and a hydraulic pump for supplying oil to the hydraulic cylinder. The hydraulic pump is fixed to the outside of the drying box through a mounting bracket. The hydraulic cylinder includes two, and the cylinder bodies of the two hydraulic cylinders are respectively fixed on both sides of the hydraulic pump through a connecting frame. The telescopic column of the hydraulic cylinder passes through the side wall of the drying box and is connected to the shovel plate. The hydraulic pump and the cylinder body are connected by hydraulic pipe fittings.
[0009] Furthermore, a brush cylinder is provided on the side wall of the drying box, a hard brush is provided inside the brush cylinder, and the telescopic column is slidably connected to the brush cylinder; a push plate is provided at the end of the telescopic column, and the shovel plate is fixed on the push plate.
[0010] Furthermore, a guide hopper is provided below the lower end of the heat conduction inclined plate, the guide slope is provided below the guide hopper, and the stirring rod is rotatably provided between the guide hopper and the guide slope.
[0011] Furthermore, the first drive motor is arranged below the guide slope, and the rotating shaft of the first drive motor passes through the guide slope upward. The stirring rods include three and are rotationally symmetrically arranged on the rotating shaft of the first drive motor. Cutting knives are embedded on the outer sides of the stirring rods.
[0012] Furthermore, a plurality of crushing ball heads are evenly distributed on the surface of the crushing roller, and the motor shaft of the second drive motor is connected to the connecting shaft of the crushing roller through a transmission belt.

[0020] like Figure 1-7As shown, a small underground chamber slag discharge device provided by the present invention includes a frame 2 and a drying box 1, a crushing box 5 and a conveyor belt 4 arranged on the frame 2; a feed hopper 3 is provided on one side of the top of the drying box 1, a heat conduction inclined plate 14 is provided in the drying box 1, and the higher end of the heat conduction inclined plate 14 is located below the feed hopper 3, and an auxiliary shovel pushing assembly 7 is provided on the side of the drying box 1 away from the feed hopper 3; the auxiliary shovel pushing assembly 7 includes a shovel plate 76 whose front end contacts the upper surface of the heat conduction inclined plate 14 and a driving mechanism that can drive the shovel plate 76 to move along the inclined surface of the heat conduction inclined plate 14; the crushing box 5 is located in the drying box 1, with its top inlet located below the lower end of the heat-conducting inclined plate 14. The conveyor belt 4 is located below the bottom outlet of the pulverizing box 5. An auxiliary pulverizing assembly 8 is located within the pulverizing box 5. The auxiliary pulverizing assembly 8 comprises a stirring rod 83 located below the lower end of the heat-conducting inclined plate 14, a first drive motor 81 that drives the stirring rod 83, two horizontally arranged pulverizing rollers 85 that rotate relative to each other and a second drive motor 87 that drives the pulverizing rollers 85. A downwardly inclined guide ramp 51 is provided between the stirring rod 83 and the pulverizing rollers 85. The heat-conducting inclined plate 14 and the inner wall of the drying box 1 can be sealed with insulating material to prevent moisture and debris from falling through the gap between them and to reduce heat transfer directly from the heat-conducting inclined plate 14 to the outer wall of the drying box 1. The heat-conducting inclined plate 14 has a smooth surface, and its inclination angle ensures that the debris can slide along the heat-conducting inclined plate 14 under its own weight. The shovel plate 76 can move back and forth along the heat conduction inclined plate 14 under the drive of the driving mechanism, and the moving range is not less than 1 / 5 of the length of the heat conduction inclined plate 14.
[0021] The working process of the present invention is as follows: before working, the heat conduction inclined plate 14 is started to heat up, and the work starts when the temperature reaches about 500-800℃. First, the wet and large pieces of slag to be transported are manually poured from the feed hopper 3 into the drying box 1. When some muddy slag with more water slides along the heat conduction inclined plate 14, a large amount of water will be evaporated. When the slag reaches the bottom of the heat conduction inclined plate 14, the slag may stick to the heat conduction inclined plate 14. At the same time, the auxiliary shovel push component 7 starts to work. Driven by the driving mechanism, the shovel plate 76 moves along the heat conduction inclined plate The shovel 76 moves back and forth, scooping up any debris stuck to the heat-conducting inclined plate 14. The debris then falls into the crushing box 5 below as the shovel plate 76 retracts. The debris then passes through the area where the stirring rod 83 is located. The stirring rod 83 rotates, breaking up any agglomerated or large debris into smaller pieces. These small pieces, propelled by the guide ramp 51 and the stirring rod 83, enter the area where the crushing rollers 85 are located. The two crushing rollers 85 rotate relative to each other, crushing the small pieces into even smaller particles. Finally, the granular debris falls onto the conveyor belt 4, which delivers it to the belt conveyor that transports the debris outward. This completes the entire process of heating, crushing, and conveying the debris, ensuring stable and safe transportation of the debris.
[0022] like Figure 2 、 Figure 4 As shown, to prevent excess moisture from evaporating within drying box 1, an air outlet 11 is provided at the top end of drying box 1, away from feed hopper 3. Protective grilles 12 are provided on both the inside and outside of air outlet 11, and a fan 13 is installed within air outlet 11. Fan 13 is always operational upon startup, continuously discharging moisture from drying box 1 to ensure effective drying.
[0023] Regarding the specific structure of the heat conducting inclined plate 14, the preferred embodiment of the present invention is as follows: Figure 4 、 Figure 5 、 Figure 7 As shown, the heat-conducting inclined plate 14 is made of metal and has multiple electric heating rods 15 embedded within it. A controller 16 is located at the bottom. The controller 16 is electrically connected to each electric heating rod 15 via cables 17. A humidity sensor 52 is located within the drying box 1 or the crushing box 5 and is electrically connected to the controller 16. During operation, the humidity sensor 52 detects the humidity inside the crushing box 5 to determine the dryness of the soil and transmits this data to the controller 16. The controller 16 then regulates the output power of the electric heating rods 15 to ensure the drying effect and save energy.
[0024] Regarding the driving mechanism for driving the shovel plate 76 to move, the preferred embodiment of the present invention is as follows: Figure 4 As shown, the drive mechanism includes a hydraulic cylinder and a hydraulic pump 71 that supplies oil to the hydraulic cylinder. The hydraulic pump 71 is fixed to the outside of the drying box 1 via a mounting bracket 72. The hydraulic cylinders include two, and their cylinder bodies 73 are fixed to either side of the hydraulic pump 71 via connecting brackets 731. The connecting brackets 731 and the mounting bracket 72 can be integrated into one structure. The hydraulic cylinder's telescopic column 75 passes through the side wall of the drying box 1 and is connected to the shovel plate 76. The hydraulic pump 71 and cylinder body 73 are connected via a hydraulic pipe 74. Using a single hydraulic pump 71 to supply oil to both hydraulic cylinders simultaneously ensures synchronous movement of the two hydraulic cylinders, thereby improving the smooth movement of the shovel plate 76.
[0025] During operation of the drive mechanism, some debris may adhere to the telescopic column 75. To prevent this debris from entering the cylinder 73, a brush barrel 78 is installed on the side wall of the drying box 1. This brush barrel 78 is equipped with a hard-bristled brush, and the telescopic column 75 slides through the brush barrel 78. When the telescopic column 75 retracts, the debris on its surface is scraped off by the hard-bristled brush inside the brush barrel 78, thus ensuring stable operation of the hydraulic cylinder. Furthermore, because the shovel plate 76 is typically a planar structure, a push plate 77 is installed at the end of the telescopic column 75 to enhance its connection strength with the telescopic column 75. The shovel plate 76 is fixed to the push plate 77. The push plate 77 is constructed of a hard metal strip and evenly transmits the thrust from the telescopic column 75 to the push plate 77.
[0026] In addition, the present invention also provides the following preferred solutions: like Figure 4 、 Figure 6 As shown, a guide hopper 18 is provided below the lower end of the heat conduction inclined plate 14, the guide slope 51 is provided below the guide hopper 18, and the stirring rod 83 is rotatably provided between the guide hopper 18 and the guide slope 51. The guide hopper 18 can collect the debris sliding down from the heat conduction inclined plate 14, making it convenient for the stirring rod 83 to disperse it.
[0027] like Figure 6 As shown, the first drive motor 81 is disposed below the guide ramp 51, with its rotating shaft 82 extending upward through the guide ramp 51. Three stirring rods 83 are rotationally symmetrically arranged on the rotating shaft 82 of the first drive motor 81, with cutting blades 84 embedded on the outer surfaces of the stirring rods 83. The three stirring rods 83 with cutting blades 84 enhance the soil disintegration effect. Furthermore, because the first drive motor 81 is disposed below the guide ramp 51, a sealing connector 821 may be provided at the junction of the rotating shaft 82 and the guide ramp 51 to prevent soil and water from entering the first drive motor 81.
[0028] like Figure 6 、 Figure 7 As shown, the surface of the crushing roller 85 is uniformly distributed with multiple crushing balls 851. The motor shaft 871 of the second drive motor 87 is connected to the connecting shaft 86 of the crushing roller 85 via a transmission belt 88. The crushing balls 851 enhance the crushing effect of soil and rocks. The second drive motor 87 can be positioned above the crushing roller 85 to prevent soil and water from interfering with its operation. This also allows for better utilization of the space below the heat conducting ramp 14, making the equipment more compact.
[0029] like Figure 6 As shown, in order to facilitate the connection between the conveyor belt 4 and the belt conveyor that transports the debris outward, the conveyor belt 4 needs to be set into a structure that is inclined upward. At the same time, in order to prevent the debris from sliding, multiple barrier strips 41 can be set at equal intervals on the outer surface of the conveyor belt 4.
[0030] Finally, in order to facilitate the operation of the equipment, a control panel 6 is provided on the outer wall of the drying box 1. The control panel 6 is electrically connected to the electrical components in the drying box 1, the crushing box 5 and the conveyor belt 4, that is, the drying box 1, the crushing box 5 and the conveyor belt 4 can be controlled by the control panel 6 to operate according to the above-mentioned work flow.
