[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a dust reduction device, which includes: a dust removal host 10, a dust suction pipeline 20 and a frequency converter 30. The dust removal host 10 has a accommodating chamber, an air inlet and an air outlet, the accommodating chamber is connected to the air inlet and the air outlet respectively, a detection mechanism is arranged in the accommodating chamber, and the detection mechanism is arranged at the air inlet to detect parameter data in the air of the lane. One end of the dust suction pipeline 20 is connected to the air inlet, and the other end of the dust suction pipeline 20 is connected to the lane. The frequency converter 30 is electrically connected to the detection mechanism and the dust removal host 10 respectively, and the frequency converter 30 adjusts the output power of the dust removal host 10 according to the parameter data.

[0030] By applying the technical solution of the utility model, a detection mechanism is provided inside the dust removal host 10, and the dust removal host 10 can detect the parameters of the air in the lane through the detection mechanism, and perform dust removal on the air in the lane through the dust suction pipeline 20, and the frequency converter 30 is electrically connected to the detection mechanism and the dust removal host 10. Through the above-mentioned setting, when the parameter data detected by the detection mechanism is abnormal, the frequency converter 30 will adjust the output power of the dust removal host 10, so as to suck the air in the lane into the dust removal host 10 through the dust suction pipeline 20 for dust removal, and then discharge it through the air outlet until the detection parameters of the detection mechanism return to normal. In this way, when the air parameters in the lane are abnormal, the output power of the dust removal host 10 can be automatically adjusted at any time, and the air parameters in the lane can be restored to normal as soon as possible in cooperation with the dust suction pipeline 20, so as to ensure that the air environment of the staff in the lane is normal, improve the pertinence and flexibility of dust removal, greatly improve the dust removal effect in the lane, and have a simple structure.

[0031] The parameter data in the air may include dust concentration, gas concentration, carbon dioxide and other concentrations of gases that are harmful to the human body.

[0032] Specifically, the dust removal host 10 includes: a casing, a fan and a filter. Among them, the accommodating chamber, the air inlet and the air outlet are all arranged on the casing. The fan is arranged inside the accommodating chamber. The filter is located in the accommodating chamber and is arranged between the fan and the air inlet. Through the above arrangement, the fan provides driving force for the dust suction pipeline to suck the air in the alley into the dust removal host. Preferably, the frequency converter 30 is electrically connected to the fan in the dust removal host 10. In this way, when the detection mechanism detects that the air parameter data in the alley is abnormal, the output power of the fan can be increased by the frequency converter 30 to enhance the suction force on the air in the alley, and the air with abnormal parameters is sucked into the dust removal host 10 as soon as possible for dust removal and filtration, so as to avoid harm to the bodies of the staff in the alley.

[0033] Specifically, a filter channel is provided in the dust removal host 10, one end of the filter channel is connected to the air inlet, and the other end of the filter channel is connected to the air outlet. The filter element and the fan are both arranged in the filter channel, the fan is arranged near the air outlet, and the filter element is arranged between the fan and the air inlet, and the air sucked into the dust suction pipeline is filtered and dusted. The filter element can be set as a filter plate, a filter net or a filter membrane. Through the above arrangement, the structure is simple and easy to disassemble and repair.

[0034] Due to factors such as humidity, high temperature and high pressure in the well, the dust suppression devices in the prior art waste water resources, the sensors are prone to failure, and the solenoid valves are easily damaged. The dust suppression device provided by the present application does not use water injection to suppress dust, but separates and filters the dust particles in the air through the filter element, and does not require additional water storage equipment, which further saves dust suppression costs and reduces the waste of water resources.

[0035] Furthermore, the housing also has a dust discharge port, which is arranged corresponding to the filter element, and the dust reduction device also includes a dust collection bucket 40, which is connected to the dust discharge port and is used to collect impurities filtered by the filter element. The dust discharge port is connected to the filter channel. Through the above arrangement, it is convenient for the staff to centrally collect and process the filtered dust particles.

[0036] The dust reduction device further includes a first exhaust pipe 51 and a second exhaust pipe 52 which are relatively independently arranged. The air outlet can be selectively connected to the first exhaust pipe 51 or the second exhaust pipe 52. The first exhaust pipe 51 is connected to the ground, and the second exhaust pipe 52 is connected to the tunnel. Through the above arrangement, when the detection mechanism detects that the concentration of gas or other flammable, explosive and harmful gases in the air in the tunnel is abnormal, it will be discharged to the ground through the first exhaust pipe 51 for further filtering and purification. When the detection mechanism detects that only the dust content in the air in the tunnel is abnormal, it can be discharged back to the tunnel from the second exhaust pipe 52 after filtering through the filter element in the dust removal main unit 10. In this way, air circulation can be carried out, and the safety of work is guaranteed, so that the air environment inside the tunnel is always in a good state, and the production environment in the tunnel is improved.

[0037] Specifically, control valves are provided on both the first exhaust pipe 51 and the second exhaust pipe 52 to control the on-off of the first exhaust pipe 51 and the second exhaust pipe 52 .

[0038] In the present application, the dust suction pipe 20 has a first dust suction pipe 21, a second dust suction pipe 22 and a third dust suction pipe 23 which are arranged in sequence. The first dust suction pipe 21, the second dust suction pipe 22 and the third dust suction pipe 23 are all connected to the air inlet. The first dust suction pipe 21 and the third dust suction pipe 23 are respectively fixed on both sides of the lane, and the second dust suction pipe 22 is fixed on the top of the lane. Through the above arrangement, the dust suction pipe 20 is fixed along the structure of the side wall of the lane, which can better perform more complete suction and detection of the air in the entire cross section of the lane along the ventilation direction, expand the suction range of the dust suction pipe 20, and can avoid the situation that when only the air at the bottom or top of the lane has abnormal parameters, the air with abnormal parameters cannot be sucked into the dust removal host 10 for detection, further improving the practicality of the dust reduction device and the comprehensiveness of the detection range coverage to ensure the normal production environment in the lane.

[0039] In the present application, there is no limitation on the materials of the first dust suction tube 21, the second dust suction tube 22 and the third dust suction tube 23. They can be set as flexible hoses, rigid metal tubes, or semi-flexible and semi-rigid combination pipes, depending on the specific application scenario.

[0040] Among them, the first dust suction pipe 21, the second dust suction pipe 22 and the third dust suction pipe 23 can be fixed to the inner wall of the tunnel by anchor cables, anchor rods, etc., and can also be fixed to the inner wall of the tunnel by fasteners or fixing frames, which is not limited in this embodiment.

[0041] Specifically, a plurality of suction ports 25 are arranged at intervals on the dust suction pipeline 20. Through the above configuration, the plurality of suction ports 25 are arranged at intervals on the dust suction pipeline 20 to improve the dust suction efficiency of the dust suction pipeline 20, and at the same time, the dust suction coverage of the dust suction pipeline 20 can be further expanded.

[0042] In this embodiment, the dust suction port 25 is configured as a conical structure and is fixedly connected to the dust suction pipe 20. The aperture of the opening gradually increases in the direction away from the dust suction pipe 20. Such a configuration can increase the dust suction range of the dust suction port 25, thereby increasing the dust suction amount of a single dust suction port 25.

[0043] In other embodiments of the present application, the dust suction port 25 can also be rotatably connected to the dust suction pipeline 20 and electrically connected to the dust removal host 10. The rotation direction of the dust suction port 25 can be adjusted and controlled. Such a setting can further enhance the pertinence and flexibility of the dust reduction device in dust suction. When the detection mechanism detects that the air gas parameters in a certain direction of the alley are abnormal, the direction of the dust suction port 25 can be adjusted to suction in a specific direction. At the same time, the output power of the dust removal host 10 is increased, the suction force is increased, and the air with abnormal parameters is quickly sucked into the dust removal host 10 for filtering.

[0044] Furthermore, there are multiple dust removal hosts 10 and detection mechanisms, and multiple dust removal hosts 10 and multiple detection mechanisms are set in one-to-one correspondence, and the frequency converter 30 adjusts the output power of the corresponding dust removal host 10 according to the parameter data of the detection mechanism. Through the above settings, multiple dust removal hosts 10 can increase the output power of the dust removal device, thereby meeting the suction demand with a large air volume. In this embodiment, three dust removal hosts 10 are set in parallel. In other embodiments of the present application, 2, 5 or 8 dust removal hosts 10 can also be set. Among them, a frequency converter 30 can be set in each dust removal host 10, or a frequency converter 30 can be set in parallel with multiple dust removal hosts 10. And when multiple dust removal hosts 10 are set in parallel, the air outlets of each dust removal host 10 are connected to the same first exhaust pipe 51 and second exhaust pipe 52.

[0045] In the present application, there are multiple groups of dust suction pipelines 20, and the multiple groups of dust suction pipelines 20 are arranged one by one with the dust removal host 10, and the multiple groups of dust suction pipelines 20 are distributed at intervals along the extension direction of the lane. Through the above arrangement, the multiple groups of dust suction pipelines 20 can suck and detect the air of the entire lane, which improves the convenience of dust reduction of the device, and the above structure is simple, does not occupy too much space in the lane, and avoids interference with other working equipment in the lane to affect the normal work of the staff.

[0046] The detection mechanism includes a dust detector 61 and a gas concentration detector 62, and the frequency converter 30 is electrically connected to the dust detector 61 and the gas concentration detector 62. Through the above configuration, the frequency converter 30 can be driven by the parameters detected by the dust detector 61 and the gas concentration detector 62, thereby controlling the output power of the fan, thereby adjusting the suction force of the dust suction pipeline 20.

[0047] In the present application, the dust detector 61 and the gas concentration detector 62 are arranged at the air inlet to detect the dust concentration and the gas concentration in the air before filtration. In one embodiment of the present application, when multiple dust removal hosts 10 are arranged in parallel, only one gas concentration detector 62 can be arranged, which is arranged at the connection between the first exhaust pipe 51 and the second exhaust pipe 52. When the detection value is abnormal, the suction strength of all dust removal hosts 10 is increased.

[0048] In the present application, an alarm is also provided in the accommodation chamber, and the alarm is electrically connected to the gas concentration detector 62. Through the above arrangement, when the gas concentration detector 62 detects that the gas concentration of the air in the tunnel exceeds the standard, the alarm will sound an alarm to prompt and warn the staff.

[0049] Specifically, when the dust reduction device provided in the present application reduces dust in the air in the tunnel, the working process is as follows:

[0050] The first method: when the dust removal host 10 is started, the dust suction pipeline 20 is dust suctioning, and the dust detector 61 and the gas concentration detector 62 are working. When the detection shows that the dust concentration exceeds the standard, but the gas concentration is normal, the power of the fan is increased by controlling the frequency converter 30, thereby enhancing the suction capacity of the dust suction pipeline 20, sucking the gas in the lane into the dust removal host 10 for filtration, and then the filtered gas is discharged to the lane, and the filtered dust is discharged to the dust removal bucket;

[0051] The second method: when the dust removal host 10 is started, the dust suction pipeline 20 starts to suction dust, and the dust detector 61 and the gas concentration detector 62 work at this time. When the detection shows that the dust concentration is normal, but the gas concentration exceeds the standard, the alarm starts to alarm, and at the same time, the power of the fan is increased by controlling the frequency converter 30, thereby enhancing the suction capacity of the dust suction pipeline 20, sucking the gas in the lane into the dust removal host 10 for filtration, and then the filtered gas is discharged to the ground, and the filtered dust is discharged to the dust removal bucket;

[0052] The third method: when the dust removal host 10 is started, the dust suction pipeline 20 performs dust suction, and the dust detector 61 and the gas concentration detector 62 work at this time. When the detection shows that the dust concentration and the gas concentration are normal, the output power of the fan remains unchanged, and the gas in the lane is sucked into the dust removal host 10 for filtration, and then the filtered gas is discharged to the lane, and the filtered dust is discharged to the dust removal bucket;

[0053] The fourth type: when the dust removal host 10 is started, the dust suction pipeline 20 starts to suction the dust. At this time, the dust detector 61 and the gas concentration detector 62 are working. When the detection shows that the dust concentration and the gas concentration are both abnormal, the alarm starts to alarm to prompt the staff. At the same time, the power of the fan is increased by controlling the frequency converter 30, thereby enhancing the suction capacity of the dust suction pipeline 20, and the gas in the tunnel is sucked into the dust removal host 10 for filtration, and then the filtered gas is discharged to the ground, and the filtered dust is discharged to the dust removal bucket.
