Description

Technical Field

[0001] The utility model relates to the field of coal mining, in particular to a device for quickly sealing a collapsed bunker. Background Art

[0002] Silo breach accidents often occur in silos that temporarily store coal. The moisture generated during the coal mining process will enter the silo along with the raw coal. The silo is prone to arch blockage due to long-term use, and condensate will form on the silo wall, leading to blockage of coal flow. After drainage, when the moisture in the silo reaches a certain level, the fluidity of the raw coal in the silo will increase, and the coal chute gate will be difficult to control, which can easily cause a silo breach accident and endanger the safety of personnel and equipment.

[0003] When a bunker collapses, the coal flow has a large impact force, and the existing gate is difficult to close in time under the huge impact force, resulting in damage to the bunker feeder. Underground coal bunkers are an important part of the normal production of coal mines. Once a bunker collapse accident occurs, the accident working face or the entire production link will stop working, and even worse, it will cause casualties to surrounding workers.

[0004] Existing similar coal bunker breach sealing devices are installed at the coal feeder outlet. When a bunker breach accident occurs, the huge impact force makes it impossible to close the bunker gate, and the impact causes damage to the coal feeder, causing the bunker sealing device to lose its effectiveness along with the coal feeder, and the controllability of the coal flow rate cannot be guaranteed when the coal bunker gate is opened, posing certain safety hazards.

DETAILED DESCRIPTION

[0022] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0024] Embodiment 1:

[0025] A device for quickly sealing a collapsed bin comprises a bin 1 and a material receiving device 4 arranged below the bin 1, a discharging chute 3 connected to the bin 1 and arranged obliquely is arranged below the bin, a bin sealing device 2 is arranged on the discharging chute 3, and the bin sealing device comprises a frame 205, the frame 205 is obliquely fixed to the outer wall of the discharging chute 3 by flange bolts and is perpendicular to the discharging chute 3, and a pressure relief plate 201 and a sealing plate 202 that can move back and forth along the length direction of the frame 205 and can extend into the inner cavity of the discharging chute 3 are matched between the two side walls of the frame 205, the pressure relief plate 201 is placed directly above the sealing plate 202, and the pressure relief plate 201 is provided with a plurality of rods 207 arranged at intervals along the length direction of the pressure relief plate 201.

[0026] Specifically, the side walls on both sides of the frame 205 are respectively provided with a first guide hole 208 and a second guide hole 209 which are arranged along the length direction of the frame 205. The pressure relief plate 201 and the sealing plate 202 can respectively move along the length direction of the frame 205 through the first guide hole 208 and the second guide hole 209 in sequence.

[0027] In the implementation process of the utility model, when the silo 1 is breached, the pressure relief plate 201 is pushed so that the pressure relief plate 201 is inserted into the inner cavity of the discharge chute 3 along the first guide hole 208. The end of one end of the rod 207 is designed as a conical structure, which can effectively reduce the resistance of the pressure relief plate 201 when it is inserted. After the rod 207 is inserted, most of the impact force of the coal flow will act on the rod 207, thereby effectively reducing the impact force of the coal flow on the receiving device 4. It should be noted that since the utility model is also provided with an inclined discharge chute 3 below the silo 1, the discharge chute 3 can also reduce the vertical downward impact force of the coal flow. Therefore, under the action of the discharge chute 3 and the rod 207 of the pressure relief plate 201, the impact force of the coal flow on the receiving device 4 is greatly reduced, avoiding equipment damage and casualties. After the above operation, the sealing plate 202 is inserted into the inner cavity of the discharge chute 3 along the length direction of the frame 205 through the second guide hole 209. Since the velocity and flow rate of the coal flow are effectively reduced, the impact force received by the sealing plate 202 during the insertion process will be very small, and the chamber can be easily sealed at this time.

[0028] It should be noted that when the bunker is completely sealed by the bunker sealing device 2, the accumulated water in the bunker 1 will accumulate in the bunker 1. During the implementation process, water-permeable micropores can be provided on the surface of the sealing plate 202, and the accumulated water in the bunker can be discharged through the gaps between the adjacent bars 207 and the water-permeable micropores on the sealing plate 202, thereby achieving the purpose of drainage. Furthermore, the height difference between the pressure relief plate 201 and the sealing plate 202 is 50mm-100mm, so as to avoid motion interference between the pressure relief plate 201 and the sealing plate 202 under the interference of the coal flow.

[0029] It should be further explained that the utility model can also reduce the impact force of coal flow during the process of opening the warehouse to discharge materials, which is specifically manifested as follows: when preparing to open the warehouse to discharge materials, the sealing plate 202 is opened to a certain extent, and the pressure relief plate 201 is kept closed at this time, which blocks the coal flow to a certain extent, and avoids the instantaneous impact of the instantaneous coal flow on the receiving device 4 caused by the instantaneous coal flow after the traditional valve is directly opened. Through the warehouse sealing device provided by the utility model, the sealing plate 202 is first opened to a certain extent, and the coal flow rate is observed until the warehouse opening is fully opened after the coal flow moves normally, so as to avoid the impact of coal flow caused by the rapid opening of the sealing plate 202, thereby protecting the receiving device and ensuring the safety of surrounding workers.

[0030] Embodiment 2:

[0031] In this embodiment, the side wall of the frame 205 is provided with a first hydraulic cylinder 203 and a second hydraulic cylinder 204, the pressure relief plate 201 is fixedly connected to the telescopic end of the first hydraulic cylinder 203, the sealing plate 202 is fixedly connected to the telescopic end of the second hydraulic cylinder 204, the first hydraulic cylinder 203 and the second hydraulic cylinder 204 are connected with an electrical control system for controlling the telescopic amount of the first hydraulic cylinder and the second hydraulic cylinder, and the electrical control system controls the first hydraulic cylinder 203 and the second hydraulic cylinder 204 to extend and drive the pressure relief plate 201 and the sealing plate 202 to seal the warehouse. Specifically, when a warehouse collapse accident occurs, the electrical control system sends a warehouse collapse signal to control the first hydraulic cylinder 203 to drive the pressure relief plate 201 to seal the warehouse and reduce the impact force of the coal flow. When the pressure relief plate 201 is completely closed, the electrical control system sends a control signal to control the second hydraulic cylinder 204 to extend and drive the sealing plate 202 to seal the warehouse, thereby achieving the purpose of rapid warehouse sealing. It should be noted that the first hydraulic cylinder 203 and the second hydraulic cylinder 204 both include two cylinders fixed on the pressure relief plate 201 and the sealing plate 202 respectively, so as to ensure uniform force and enhance the stability of the pressure relief plate 201 and the sealing plate 202 during movement.

[0032] Accordingly, when opening the bin to discharge materials, the electrical control system first controls the sealing plate 202 to open to a certain extent and maintain it for a certain period of time, and the pressure relief plate 201 remains closed, reducing the instantaneous impact of the coal flow when the sealing plate 202 is suddenly opened. Thereafter, the electrical control system controls the sealing plate 202 and the pressure relief plate 201 to fully open and discharge materials normally, thereby protecting the receiving device and ensuring the safety of the surrounding staff. Preferably, the electrical control system is electrically connected to an accumulator 5 to ensure that the bin sealing device can still operate normally under extreme conditions such as sudden power failure, thereby improving the reliability of the device.

[0033] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
