Description

Technical Field

[0001] This utility model relates to the field of coal mine heating technology, specifically an energy-saving underground coal mine heating system. Background Technology

[0002] Coal mines refer to places rich in coal resources. Mining areas are generally located in remote areas. Large power grids and centralized heating networks are not economically viable solutions to the energy needs of coal mining areas, which has led to the development of various devices that utilize coal mine gas for heating.

[0003] In response, Chinese patent application number CN202122292410.6 discloses a mining area heating device, including a collection pipe, a gas storage tank, a mixing device, and a combustion device. The gas outlet of the mixing device is connected to the combustion device. Two gas inlets of the mixing device are respectively connected to the gas storage tank and the collection pipe. The gas storage tank is connected to the collection pipe. Regulating valves are installed between the gas storage tank, the collection pipe, and the mixing device. This utility model's mining area heating device can store high-concentration methane gas through the gas outlet pipe, thereby supplementing the methane concentration when it is insufficient, ensuring stable operation of the combustion device, and thus ensuring normal use of the heating device.

[0004] The heating device can mix gas by setting up a mixing device. However, the gas enters the combustion device directly after passing through the vent without undergoing any other action, which cannot guarantee the mixing effect and will result in poor heating effect.

[0005] Therefore, in order to solve the above problems, an energy-saving underground coal mine heating system is proposed. Summary of the Invention

[0006] The purpose of this utility model is to provide an energy-saving underground coal mine heating system to solve the problem mentioned in the background art that in the prior art heating device, a mixing device can be set up to mix the gas, but the gas enters the combustion device from the gas hole without undergoing other action, which cannot guarantee the mixing effect and thus leads to poor heating effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving underground coal mine heating system, comprising: an outer shell, an upper gas distribution plate installed on the inner top surface of the outer shell, an upper spray pipe connected to the bottom surface of the upper gas distribution plate, a gas storage inlet connected to the top surface of the upper gas distribution plate, a lower gas distribution plate installed on the inner bottom surface of the outer shell, a lower spray pipe connected to the top surface of the lower gas distribution plate, a gas collection inlet connected to the bottom surface of the lower gas distribution plate, and an outlet connected to the right side wall of the outer shell;

[0008] A hybrid structure is installed on the inner side of the housing. The hybrid structure includes a movable disk, which is movably installed in the middle of the inner side of the housing. A through hole is opened on the surface of the movable disk. A threaded rod is movably installed on the inner side of the housing through a bearing. A motor is fixedly installed on the top surface of the housing.

[0009] Preferably, the gas storage inlet and the gas collection inlet extend through the upper and lower sides of the outer casing, respectively.

[0010] Preferably, the upper spray pipe and the lower spray pipe are staggered.

[0011] Preferably, the movable disc is located between the upper air distribution disc and the lower air distribution disc, and the diameter of the movable disc is smaller than the inner diameter of the outer shell.

[0012] Preferably, the inner diameter of the through hole is larger than the outer diameter of the upper and lower spray pipes, and the through hole is vertically aligned with the upper and lower spray pipes.

[0013] Preferably, the output end of the motor is fixedly connected to the threaded rod, and the threaded rod is threadedly connected to the movable disc.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting up a movable plate that can move up and down, this utility model can push the gas discharged through the upper and lower nozzles to flow up and down, so that the gas from the two sources can be fully mixed, ensuring the concentration of gas and thus improving the heating effect.

[0015] This invention features a mixing structure. Gas enters the inner shell through a gas storage inlet and a gas collection inlet, and is then distributed to the upper and lower spray pipes via the upper and lower gas distribution plates before being discharged. The two types of gas accumulate within the shell. When the motor is started, it drives a threaded rod to rotate. The threaded rod is threadedly connected to a movable disc, and the rotation of the threaded rod causes the movable disc to move up and down within the shell. The movable disc, in conjunction with the shell, compresses the gas in the direction of movement, allowing it to flow through the through-hole and the gap between the upper and lower spray pipes. This mixing improves the gas mixing effect, ensures the gas concentration inside the shell, and facilitates the gas's delivery to the combustion device for heating via the outlet.

The mixing structure 2 includes a movable disc 21, which is movably installed in the middle of the inner side of the outer casing 1. A through hole 22 is opened on the surface of the movable disc 21. A threaded rod 23 is movably installed on the inner side of the outer casing 1 through a bearing. A motor 24 is fixedly installed on the top surface of the outer casing 1. The movable disc 21 can move up and down, which can push the gas discharged through the upper nozzle 12 and the lower nozzle 15 to flow up and down, so that the gas from the two sources can be fully mixed, ensuring the concentration of gas and thus improving the heating effect.

[0025] Furthermore, the gas storage inlet 13 and the gas collection inlet 16 penetrate the upper and lower surfaces of the outer shell 1, respectively. The stored gas and the collected gas can be introduced into the outer shell 1 through the gas storage inlet 13 and the gas collection inlet 16, respectively.

[0026] Furthermore, the upper nozzle 12 and the lower nozzle 15 are staggered, allowing gas to be introduced into the outer casing 1 for initial mixing.

[0027] Furthermore, the movable plate 21 is located between the upper gas distribution plate 11 and the lower gas distribution plate 14. The diameter of the movable plate 21 is smaller than the inner diameter of the outer shell 1. The movable plate 21 can move between the upper gas distribution plate 11 and the lower gas distribution plate 14, and the gas can flow in the gap between the movable plate 21 and the outer shell 1.

[0028] Furthermore, the inner diameter of the through hole 22 is larger than the outer diameter of the upper nozzle 12 and the lower nozzle 15. The through hole 22 is aligned vertically with the upper nozzle 12 and the lower nozzle 15, and the movable disc 21 can move outside the upper nozzle 12 and the lower nozzle 15 through the through hole 22.

[0029] Furthermore, the output end of the motor 24 is fixedly connected to the threaded rod 23, and the threaded rod 23 is threadedly connected to the movable disc 21. The motor 24 provides power for the rotation of the threaded rod 23, and the rotation of the threaded rod 23 can drive the movable disc 21 to move up and down.

[0030] Working principle: When in use, the gas can enter the inner side of the outer shell 1 through the gas storage inlet 13 and the gas collection inlet 16, and then be distributed to the upper nozzle 12 and the lower nozzle 15 through the upper gas distribution plate 11 and the lower gas distribution plate 14 respectively before being discharged. The two types of gas can accumulate inside the outer shell 1.

[0031] The motor 24 is started, which drives the threaded rod 23 to rotate. The threaded rod 23 is threadedly connected to the movable disc 21. The rotation of the threaded rod 23 drives the movable disc 21 to move up and down inside the outer shell 1. The movable disc 21, in conjunction with the outer shell 1, can compress the gas in the direction of movement, so that the gas flows through the gap between the through hole 22, the upper nozzle 12 and the lower nozzle 15, which can mix the two types of gas, improve the mixing effect of the gas, ensure the concentration of gas inside the outer shell 1, and facilitate the gas to be delivered to the combustion device through the outlet 17 for heating.
