Technical Field
[0001] This utility model relates to the technical field of smoke purification devices for mine roadway fires, specifically a rapid smoke purification device for mine roadway fires. Background Technology
[0002] The rapid purification device for smoke from mine roadway fires is a specialized device for purifying smoke during mine roadway fires. Its main purpose is to quickly purify the smoke in the roadway during a fire to ensure air quality and personnel safety in the mine.
[0003] In a rapid purification system for fire smoke in mine roadways, the pre-filter, as a primary protection unit, can effectively intercept suspended particles with a diameter >50μm. However, under continuous processing of high-concentration smoke and dust, the stratification effect of particles on the filter surface can lead to a reduction in the cross-sectional area of the airflow channel of more than 60%, which in turn causes structural blockage of the filter, increases the load on the suction pump, and ultimately leads to a decrease in the system's airflow coefficient. Utility Model Content
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] Given the aforementioned or existing technologies, in current rapid smoke purification systems for mine roadway fires, the pre-filter, as a primary protection unit, can effectively intercept suspended particles with a diameter >50μm. However, under continuous processing of high-concentration smoke and dust, the stratification effect of particles on the filter surface leads to a reduction in the cross-sectional area of the airflow channel of more than 60%, which in turn causes structural blockage of the filter, increases the load on the intake pump, and ultimately leads to a decrease in the system's airflow coefficient.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A rapid purification device for smoke from a mine roadway fire includes a solvent tank, an air suction pipe connected to the bottom of the solvent tank, a pump installed in the middle of the air suction pipe, an air suction frame connected to one end of the air suction pipe, multiple sets of air suction branch pipes connected at equal intervals on the air suction frame, an air suction head connected to one end of the air suction branch pipe, and a rotating cleaning component provided on the air suction head.
[0008] As a further embodiment of this utility model: the rotating cleaning component includes a receiving box, and the receiving box is arranged in multiple sets. The multiple sets of receiving boxes are independently connected to the suction head. Each set of receiving boxes has a filter plate slidably connected inside. One end of the filter plate is fixedly connected to a pull rod that penetrates the inside of the receiving box. An electric push rod that is kinetically connected to one end of the pull rod is installed on the outside of the suction head.
[0009] As a further embodiment of this utility model: the rotating cleaning component also includes a support rod, which is fixedly connected inside the suction head. A rotating shaft is rotatably mounted on one end of the support rod, and a brush plate is fixedly connected to one end of the rotating shaft.
[0010] As a further embodiment of this utility model: the rotating cleaning assembly also includes a transmission rod and a drive motor. The transmission rod is rotatably installed inside the suction head. A bevel gear set is provided between one end of the transmission rod and one end of the rotating shaft. One end of multiple sets of transmission rods rotatably passes through the inside of the suction head. A pulley set is provided between the multiple sets of transmission rods. The drive motor is installed on the outer wall of the suction head, and the drive motor is connected to the pulley set by transmission.
[0011] As a further embodiment of this utility model: a stirring motor is installed on the outer wall of the solvent tank, a stirring rod that is rotatably installed inside the solvent tank and is connected to the stirring motor, and an exhaust pipe is connected to the top of the solvent tank.
[0012] As a further embodiment of this utility model: a first purification box is installed on one side of the outer wall of the solvent tank, and one end of the exhaust pipe is connected to the first purification box. The first purification box is equipped with multiple layers of filter elements, and one end of the first purification box is connected to an exhaust pipe.
[0013] As a further improvement of this utility model: one end of the first purification box is connected to a connecting pipe, a gas monitor is installed inside the connecting pipe, and solenoid valves are installed on both the connecting pipe and the exhaust pipe.
[0014] As a further improvement of this utility model: one end of the connecting pipe is connected to a second purification box, the second purification box is also equipped with multiple layers of filter elements, and one end of the second purification box is also connected to a smoke exhaust pipe.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. The flue gas is driven by a pump and enters the multi-branched suction frame through the suction pipe. The modular filter plate controlled by the electric push rod realizes the dynamic interception of large particles of impurities. In conjunction with the rotating brush plate driven by the bevel gear set, the dust is cleaned in real time. After a certain period of use, the spare filter plate is switched to avoid the filter plate being severely blocked and cannot be cleared by simple cleaning of the brush plate. Finally, the flue gas completes deep purification in the solvent tank.
[0017] 2. The stirring motor drives the stirring rod to rotate, which promotes the thorough mixing of the purification solvent and improves the contact efficiency with the flue gas. The flue gas, which has been initially purified, is filtered again through the multi-layer filter element inside the first purification box to remove fine particles and harmful substances. At the same time, the monitoring instrument monitors the composition of the flue gas in real time to ensure that it meets the safety emission standards. When the gas monitoring instrument detects that the flue gas does not meet the emission standards, the solenoid valve on the first purification box is closed and the solenoid valve on the connecting pipe is opened, so that the gas that does not meet the emission standards enters the second purification box for further filtration, providing additional purification protection.

[0028] Example 1
[0029] Please see Figures 1-6This is the first embodiment of the present invention, which provides a rapid purification device for smoke from a mine roadway fire. It includes a solvent tank 1, with a suction pipe 2 connected to the bottom of the solvent tank 1. A pump 3 is installed in the middle of the suction pipe 2, and a suction frame 4 is connected to one end of the suction pipe 2. Multiple sets of suction branch pipes 5 are equidistantly connected to the suction frame 4, and one end of each suction branch pipe 5 is connected to a suction head 6. A rotating cleaning assembly is provided on the suction head 6. The rotating cleaning assembly includes a receiving box 7, which is configured in multiple sets. Each set of receiving boxes 7 is independently connected to the suction head 6. The contents of each set of receiving boxes 7 are... The suction head 6 is slidably connected to a filter screen plate 8. One end of the filter screen plate 8 is fixedly connected to a pull rod 9 that penetrates the interior of the receiving box 7. An electric push rod 10, which is pulsively connected to one end of the pull rod 9, is installed on the outside of the suction head 6. The rotating cleaning assembly also includes a support rod 11, which is fixedly connected inside the suction head 6. A rotating shaft 12 is rotatably mounted on one end of the support rod 11, and a brush plate 13 is fixedly connected to one end of the rotating shaft 12. The rotating cleaning assembly also includes a transmission rod 14 and a drive motor 17. The transmission rod 14 is rotatably mounted inside the suction head 6, and a bevel gear is provided between one end of the transmission rod 14 and one end of the rotating shaft 12 for transmission. The wheel assembly 15 and multiple sets of transmission rods 14 all have one end that rotates through the interior of the suction head 6. A pulley assembly 16 is provided between the multiple sets of transmission rods 14 for transmission. The drive motor 17 is mounted on the outer wall of the suction head 6, and the drive motor 17 is connected to the pulley assembly 16 for transmission. The solvent tank 1 stores the solvent required for purifying the flue gas. The suction pipe 2 connects the solvent tank 1 and the suction frame 4, responsible for transferring the flue gas into the solvent tank 1. The pump 3 drives the intake of the flue gas. The suction frame 4 connects multiple sets of suction branch pipes 5. The suction head 6 directly contacts the flue gas for intake. The receiving box 7 houses the filter plate 8, which is used for... The filter filters large particulate impurities in the flue gas. The pull rod 9 is connected to the electric push rod 10 to control the movement of the filter plate 8. The electric push rod 10 pushes the filter plate 8 in and out of the receiving box 7 through the pull rod 9. The support rod 11 supports the rotating shaft 12, which drives the rotation of the brush plate 13. The brush plate 13 is used to clean the filter plate 8. The transmission rod 14 is used to transmit power. The bevel gear set 15 is set between the transmission rod 14 and the rotating shaft 12 to realize the transmission between the two. The pulley set 16 is used to realize the transmission between multiple sets of transmission rods 14. The drive motor 17 is used to provide power to drive the operation of the entire rotating cleaning assembly.
[0030] Operating steps: When a fire occurs, pump 3 starts, drawing smoke from the tunnel through suction pipe 2 and transmitting it to suction frame 4. Multiple suction branch pipes 5 on suction frame 4 evenly distribute the smoke to each suction head 6. Simultaneously, filter plate 8 in receiving box 7 is pushed out by electric push rod 10 via pull rod 9, exposing it to suction head 6 to begin filtering large particulate impurities in the smoke. Drive motor 17 starts, driving multiple sets of transmission rods 14 to rotate via pulley group 16. Transmission rods 14 drive rotating shaft 12 via bevel gear group 15, thereby driving the brush... The brush plate 13 rotates to clean the currently used filter plate 8. When a filter plate 8 becomes severely clogged, the electric push rod 10 retracts the filter plate 8 into the corresponding receiving box 7 via the pull rod 9. At the same time, the electric push rod 10 pushes out the filter plate 8 in another receiving box 7 to continue the filtration work. The filtered and cleaned flue gas is transmitted to the solvent tank 1 through the suction head 6, suction branch pipe 5, suction frame 4 and suction pipe 2. Inside the solvent tank 1, the flue gas comes into contact with the stored purification solvent for further purification treatment.
[0031] Furthermore, a stirring motor 18 is installed on the outer wall of the solvent tank 1, and a stirring rod 19, which is rotatably connected to the stirring motor 18, is rotatably installed inside the solvent tank 1. An exhaust pipe 20 is connected to the top of the solvent tank 1. The stirring rod 19 rotates through its connection to the stirring motor 18, thereby promoting thorough mixing of the purified solvent stored in the solvent tank 1 and improving its contact efficiency with the flue gas. In addition, the exhaust pipe 20 is also connected to the top of the solvent tank 1 to discharge the purified flue gas, ensuring the smooth completion of the entire purification process. This design improves the purification effect, helps to accelerate the flue gas treatment speed, and further ensures a safe environment within the mine.
[0032] Furthermore, a first purification box 21 is installed on one side of the outer wall of the solvent tank 1. One end of the exhaust pipe 20 is connected to the first purification box 21. The first purification box 21 is equipped with multiple layers of filter elements 22. One end of the first purification box 21 is connected to the exhaust pipe 23. The multiple layers of filter elements 22 inside the first purification box 21 can filter the flue gas that has already undergone preliminary purification again, removing any small particles and harmful substances that may remain. After being filtered by the multiple layers of filter elements 22, the flue gas is discharged through the exhaust pipe 23. This dual purification design ensures the thorough purification of the flue gas, greatly reduces the content of harmful substances in the emitted flue gas, and further protects the mine environment and the health and safety of miners.
[0033] Furthermore, one end of the first purification box 21 is connected to a connecting pipe 24, and a gas monitor 25 is installed inside the connecting pipe 24. Solenoid valves 26 are installed on both the connecting pipe 24 and the exhaust pipe 23. One end of the connecting pipe 24 is connected to a second purification box 27, which is also equipped with multi-layer filter elements 22. One end of the second purification box 27 is also connected to the exhaust pipe 23. In order to achieve more comprehensive and precise flue gas purification control, a connecting pipe 24 is connected to one end of the first purification box 21. A gas monitor 25 is installed inside the connecting pipe 24 to monitor the composition of the flue gas after preliminary purification in real time to ensure that it meets the safety emission standards. Solenoid valves 26 are installed on both the connecting pipe 24 and the exhaust pipe 23 to control the emission path of the flue gas. The function of the second purification box 27 is to filter the flue gas purified by the first purification box 21 again, providing additional purification protection.
[0034] Working steps: After filtration and cleaning, the flue gas is transported to the solvent tank 1 through the suction head 6, suction branch pipe 5, suction frame 4, and suction pipe 2. The stirring motor 18 drives the stirring rod 19 to rotate, which promotes the thorough mixing of the purification solvent and improves the contact efficiency with the flue gas. After purification, the flue gas is discharged to the first purification tank 21 through the exhaust pipe 20. The multi-layer filter element 22 inside the first purification tank 21 filters the flue gas again after preliminary purification to remove small particles and harmful substances. The gas monitor 25 inside the connecting pipe 24 monitors the flue gas composition in real time to ensure that it meets the safety emission standards. When the gas monitor 25 detects that the flue gas does not meet the emission standards, it closes the solenoid valve 26 on the first purification tank 21 and opens the solenoid valve 26 on the connecting pipe 24, so that the gas that does not meet the emission standards enters the second purification tank 27 for discharge, providing additional purification protection.
