Description

Technical Field

[0001] This utility model belongs to the field of mine ventilation and air exchange technology, and in particular relates to a mine ventilation and air exchange device for mining. Background Technology

[0002] A mine shaft is a general term for the shafts and tunnels built underground for mining purposes. The purpose of mine ventilation is to deliver fresh air into the mine, dilute and remove harmful gases and dust, regulate the underground climate, create a good working environment, and ensure safe production.

[0003] A search revealed a mine ventilation and air exchange device with high ventilation efficiency, application number 202020733378.3. The device's structure includes a housing with a frame welded to its inner cavity. An intake fan is fixedly installed on the top left side of the inner cavity. This invention, through the arrangement of a frame, intake fan, exhaust fan, motor, drive wheel, driven wheel, connecting rod, first rotating pipe, second rotating pipe, first connecting box, second connecting box, and turntable, enables the mine ventilation and air exchange device to achieve high-efficiency air exchange. It also solves the problem that most existing mine ventilation devices use exhaust fans or similar devices that transport air, which is relatively simple, only able to deliver airflow into the mine. Furthermore, the direction of airflow cannot be changed during delivery, greatly reducing the ventilation efficiency within the mine and causing a certain waste of electrical energy.

[0004] However, the above-mentioned device has a drawback in its use: the gas extracted from the mine is directly emitted without dust suppression treatment. Since the gas in the mine contains dust such as coal dust, if dust suppression treatment is not carried out, the gas will pollute the atmospheric environment and seriously affect the surrounding air quality. Utility Model Content

[0013] Compared with related technologies, the mine ventilation and air exchange device for mining provided by this utility model has the following advantages:

[0014] Beneficial effects:

[0015] Compared with existing technologies, the mine ventilation and air exchange device provided in this solution, through the combined use of a first fan and an intake pipe, can transport ambient air into the first housing, and finally discharge it from multiple upper ventilation pipes, supplying fresh air into the mine. The use of a second fan can generate suction from multiple lower ventilation pipes, drawing air from the mine into the second housing. The air in the second housing then enters the second fan and is discharged into the housing through an exhaust pipe. A dust suppression mechanism uses water spray to purify the air entering the housing, causing coal dust and other particles in the air to come into contact with the water, increasing their weight and causing them to settle. This effectively purifies the air and reduces the concentration of pollutants in the gas. The purified gas is discharged into the external environment through the exhaust pipe, solving the problem that existing mine ventilation devices cannot suppress dust in the gas extracted from the mine, resulting in atmospheric pollution and serious impact on the surrounding air quality. The use of multiple baffles increases the residence time of the gas in the shell, further improving the dust suppression effect of the dust suppression mechanism. The drive mechanism enables two rotating pipes to drive two hollow turntables to rotate, which in turn drive multiple ventilation pipes to rotate. This allows the multiple ventilation pipes above the device to evenly discharge fresh air to the surroundings, and the multiple ventilation pipes below to evenly draw in gas from the mine, thus improving the ventilation effect.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model provides a mine ventilation and air exchange device for mining, such as... Figure 1-4As shown, a mine ventilation and air exchange device for mining includes: a housing 1, on which a first fan 2 is fixedly installed on the top inner wall, and an air inlet pipe 3 is fixedly installed on the exhaust end of the first fan 2, one end of which extends to the outside of the housing 1; a first box 4 fixedly installed on the exhaust end of the first fan 2; a shell 5 fixedly installed on one side of the housing 1, on which an exhaust pipe 6 for discharging mine gases is fixedly installed; and a second fan 7 fixedly installed on the bottom inner wall of the housing 1, on which an exhaust pipe 8 is fixedly installed, one end of which extends to the shell 5. The interior of body 5; a second box 9 fixedly installed on the exhaust end of the second fan 7; two rotating pipes 10 respectively rotatably installed on the first box 4 and the second box 9, each of the two rotating pipes 10 having multiple through holes, and both rotating pipes 10 being rotatably connected to the box 1; two hollow turntables 11 respectively fixedly installed on the two rotating pipes 10, each of the two hollow turntables 11 having multiple ventilation pipes 12 fixedly installed on them for ventilation of the mine; a drive mechanism installed on the box 1 for rotating the two rotating pipes 10; and a dust suppression mechanism assembled on the housing 5 for purifying the gas.

[0024] In this embodiment, when the device is in use, such as Figure 1 The diagram illustrates that the first blower 2 draws ambient gas into the first housing 4 via the intake pipe 3. The gas then enters the upper rotating pipe 10 through multiple through-holes, then the upper hollow turntable 11, and finally exits through multiple upper ventilation pipes 12, thus supplying fresh gas to the mining shaft. During this process, the operation of the second blower 7 generates suction in the lower ventilation pipes 12, drawing gas from the mine into the lower hollow turntable 11, then into the lower rotating pipe 10, and finally into the second housing 9 through multiple through-holes. The gas in the second housing 9 then enters the second blower 7 and is discharged into the housing 5 through the exhaust pipe 8. Once inside the housing 5, the gas... The dust suppression system sprays water to reduce dust, causing coal dust and other particles in the gas to come into contact with water, increasing their weight and causing them to settle. This effectively purifies the gas and reduces its dust content. Finally, the purified gas is discharged into the external environment through the exhaust pipe 6, thus achieving air circulation within the mine. During the intake and exhaust process, the drive mechanism rotates two rotating pipes 10, which in turn rotate two hollow turntables 11. The two hollow turntables 11 then rotate multiple ventilation pipes 12, allowing the ventilation pipes 12 above to evenly release fresh air to the surroundings and the ventilation pipes 12 below to evenly draw in gas from the mine, thereby improving ventilation efficiency.

[0025] In a further preferred embodiment of the present invention, the driving mechanism includes: a support block 13 fixedly installed on the inner wall of one side of the housing 1, a motor 14 fixedly installed on the support block 13, and a first gear 15 fixedly sleeved on the output shaft of the motor 14; and a support rod 16 fixedly installed on the two rotating tubes 10, and a second gear 17 fixedly sleeved on the support rod 16, the second gear 17 meshing with the first gear 15.

[0026] In this embodiment, the drive mechanism is used to rotate the two rotating tubes 10. During operation, the motor 14 drives the first gear 15 to rotate, and the first gear 15 drives the support rod 16 to rotate through the second gear 17. The support rod 16 drives the two rotating tubes 10 to rotate, and the two rotating tubes 10 drive the two hollow turntables 11 to rotate. The two hollow turntables 11 drive the multiple ventilation pipes 12 to rotate, so that the multiple ventilation pipes 12 above the device can evenly discharge fresh air to the surroundings, and the multiple ventilation pipes 12 below can evenly draw in the gas in the mine, which is beneficial to improving the ventilation effect.

[0027] In a further preferred embodiment of this utility model, the dust suppression mechanism includes: a bottom shell 18 fixedly installed at the bottom of the housing 5 for storing water, a water pump 19 fixedly installed on the bottom inner wall of the bottom shell 18, a delivery pipe 20 fixedly installed on the drain end of the water pump 19, one end of the delivery pipe 20 extending into the interior of the housing 5; and a diversion box 21 fixedly installed on the top inner wall of the housing 5, the diversion box 21 being provided with a plurality of atomizing nozzles 22, the bottom of the diversion box 21 being fixedly connected to one end of the delivery pipe 20.

[0028] In this embodiment, the dust suppression mechanism is used to purify the gas. During operation, the water pump 19 delivers water from the bottom shell 18 to the distribution box 21 through the delivery pipe 20, and finally sprays it out from multiple atomizing nozzles 22. The sprayed water can spray the mine gas entering the shell 5, so that the coal dust and other dust in the gas come into contact with the water, causing the dust to increase in weight and settle, thereby effectively purifying the gas and reducing the dust content in the gas. Finally, the purified gas is discharged into the external environment through the gas outlet pipe 6.

[0029] In a further preferred embodiment of the present invention, the bottom of the housing 5 is provided with a plurality of water outlet holes, and a plurality of partitions 23 are fixedly installed on the inner wall of the housing 5.

[0030] In this embodiment, the use of multiple water outlets allows the sprayed water to enter the bottom shell 18 for reuse. The use of multiple baffles 23 increases the residence time of the gas in the shell 5, enabling the gas to be better treated by the dust suppression mechanism.

[0031] In a further preferred embodiment of the present invention, the inner walls of the plurality of ventilation pipes 12 are fixedly installed with mesh for blocking rodents and insects, and the conveying pipe 20 is fixedly fitted with a filter screen 24 for filtering water, and the filter screen 24 is fixedly connected to the inner wall of the bottom shell 18.

[0032] In this embodiment, the use of multiple wire meshes can prevent rodents, insects and other organisms from entering the multiple ventilation pipes 12 and causing damage to the device. The use of filter screen 24 can filter the water entering the bottom shell 18, making the filtered water cleaner.

[0033] In a further preferred embodiment of the present invention, a water inlet pipe and a water outlet pipe are fixedly installed on the bottom shell 18, and a sealing cap is threaded onto both the water inlet pipe and the water outlet pipe.

[0034] In this embodiment, by opening the sealing cap on the water inlet pipe, it is convenient for personnel to add water into the bottom shell 18, and by opening the sealing cap on the water outlet pipe, it is convenient for personnel to drain the water from the bottom shell 18.

[0035] In a further preferred embodiment of the present invention, an access port is provided on one side of the bottom shell 18, and a sealing door is provided on the access port.

[0036] In this embodiment, by opening the sealed door, personnel can easily clean the dust accumulated on the filter screen 24 at the outlet.

[0037] In summary, compared with related technologies, this solution, through the combined use of the first fan 2 and the air inlet pipe 3, can transport ambient gas into the first housing 4, and finally discharge it from the multiple upper vent pipes 12, supplying fresh gas into the mining shaft. The use of the second fan 7 generates suction in the multiple lower vent pipes 12, drawing gas from the mine shaft into the second housing 9. The gas in the second housing 9 then enters the second fan 7 and is discharged from the outlet pipe 8 into the housing 5. The dust suppression mechanism uses water spray to purify the gas entering the housing 5, causing coal dust and other particles in the gas to come into contact with the water, increasing their weight and causing them to settle, thus effectively purifying the gas and reducing its dust content. The purified gas is discharged into the external environment through the exhaust pipe 6, solving the problem that existing mine ventilation devices cannot suppress dust from the gas extracted from the mine, resulting in air pollution and serious impact on the surrounding air quality. The use of multiple baffles 23 increases the residence time of the gas in the shell 5, further improving the dust suppression effect of the dust suppression mechanism. The drive mechanism enables two rotating pipes 10 to drive two hollow turntables 11 to rotate, which in turn drive multiple ventilation pipes 12 to rotate. This allows the multiple ventilation pipes 12 above the device to evenly discharge fresh air to the surroundings, and the multiple ventilation pipes 12 below to evenly draw in gas from the mine, thus improving the ventilation effect.

[0038] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
