[0002] In the mining industry, especially during coal mining and processing, the dropping of materials easily generates a large amount of dust. This is especially true when coal is transported via a coal conveyor belt. When coal blocks fall from a high altitude, dust is easily generated.

[0003] In order to reduce the spread of dust to the surrounding environment, dust removal operations are usually carried out through bag-type dust collectors. However, the filter bags of bag-type dust collectors are easily clogged and need to be repaired or replaced regularly. They are less convenient to use in continuous mining environments. Summary of the Invention

When the secondary dust removal part is in the dust removal state, the dust outlet is closed and the clean air outlet is opened; when the secondary dust removal part is in the dust cleaning state, the dust outlet is opened and the clean air outlet is closed.

[0006] Furthermore, the dust removal device also includes a dust collection unit having an interconnected opening and a dust collection chamber. When the secondary dust removal unit is in the dust cleaning mode, the dust discharge port is connected to the opening. When the secondary dust removal unit is switched to the dust cleaning mode, dust inside the secondary dust removal unit is directly guided through the dust discharge port to the opening of the dust collection unit, and then into the dust collection chamber. This arrangement ensures that dust discharged from the secondary dust removal unit is collected promptly and effectively, preventing secondary diffusion of dust and reducing the impact on the surrounding environment.

[0007] Furthermore, multiple dust outlets and secondary dust removal units are provided, with a corresponding secondary dust removal unit located at each dust outlet. The relative position of the dust collection unit and the multiple secondary dust removal units is adjustable, and the opening of the dust collection unit can be selectively connected to the dust outlet of any secondary dust removal unit. This arrangement allows one secondary dust removal unit to be in the dust removal state while the other secondary dust removal units continue to perform dust removal operations. This arrangement avoids the need to stop the entire system when cleaning one of the secondary dust removal units, thus reducing downtime. Furthermore, the provision of a single dust collection unit can reduce the footprint of the device.

[0008] Furthermore, the plurality of secondary dust removal parts are distributed at intervals along the circumference of the first shell and the dust collection part is located on the outer periphery of the first shell.

[0009] Furthermore, the first housing includes a main body and a rotating portion, the rotating portion being rotatably mounted on top of the main body, forming a first dust removal chamber between the rotating portion and the main body, a material outlet being formed at the bottom of the main body, and multiple dust outlets being spaced apart along the circumference of the rotating portion on the sidewall of the rotating portion. This arrangement facilitates the mutual cooperation of the multiple second dust removal units with the dust collection units without interfering with each other.

[0010] The dust removal device further includes: a first solenoid valve, disposed at the dust outlet of the secondary dust removal section, for adjusting the opening of the dust outlet; a second solenoid valve, disposed at the clean air outlet of the secondary dust removal section, for adjusting the opening of the clean air outlet; and a control system, electrically connected to the first solenoid valve and the second solenoid valve, respectively, to control the operating states of the first solenoid valve and the second solenoid valve, respectively. This arrangement enables the control system to be electrically connected to the first solenoid valve and the second solenoid valve, respectively, to adjust the openings of the dust outlet and the clean air outlet, respectively. This arrangement enables the secondary dust removal section to automatically switch between a dust cleaning state and a dust removal state.

[0011] Furthermore, the dust removal device also includes: a first sensor, which is arranged on the dust collection part; a second sensor, each secondary dust removal part is provided with a second sensor, the second sensor cooperates with the first sensor, the control system is electrically connected to the second sensor, and when the first sensor senses the second sensor, the control system controls the first solenoid valve of the corresponding secondary dust removal component to open the dust outlet, and the control system controls the second solenoid valve of the corresponding secondary dust removal component to close the clean air outlet. The setting of the first sensor and the second sensor can determine whether there is a secondary dust removal part directly above the dust collection part. When the first sensor senses the second sensor, the control system controls the corresponding secondary dust removal part to switch from the dust removal state to the dust cleaning state. Such a setting further improves the degree of automation of the device.

[0012] Furthermore, the dust removal device also includes a dust flow detector, located at the dust outlet, for detecting the amount of dust discharged at the outlet. The dust flow detector is electrically connected to a control system. When the amount of dust discharged reaches zero, the control system controls the first solenoid valve of the corresponding secondary dust removal unit to close the dust outlet, and controls the second solenoid valve of the corresponding secondary dust removal unit to open the clean air outlet. This configuration allows the secondary dust removal unit to promptly switch to the dust removal state after completing its dust cleaning operation, thereby improving the operational continuity of the device.

[0013] Furthermore, the dust removal device also includes: an exhaust pipe, having an exhaust duct, an exhaust port and a connecting port, the exhaust port and the exhaust duct are connected, there are multiple connecting ports, and the multiple connecting ports are arranged along the distribution direction of the multiple secondary dust removal parts. The positions of the multiple secondary dust removal parts relative to the exhaust pipe are adjustable. When one of the secondary dust removal parts is in a cleaning state, the clean air exhaust ports of the remaining secondary dust removal parts are respectively connected to a connecting port.

[0014] Furthermore, the dust removal device further includes an exhaust component disposed on the exhaust pipe, the exhaust component being configured to exhaust air out of the exhaust port. This arrangement allows the exhaust component and the exhaust pipe to cooperate to improve the air circulation within the secondary dust removal unit when the secondary dust removal unit is in the dust removal state, thereby enabling the filtered clean air to be discharged to the external environment more quickly and reducing the time the filtered air remains in the exhaust pipe.

[0015] The application of the technical solution of the present invention facilitates dust reduction treatment during the transportation process of coal, and the convenience of cleaning dust is strong. Specifically, during the transportation of coal, when dust removal operations are required, the coal conveying device transports the coal into the first shell through the material inlet. Under the action of gravity, large pieces of coal fall through the material outlet to the bottom of the first dust removal section for the next processing link. Under the action of the dust suction section, fine particles and dust are sucked into the second dust removal section. At this time, the clean air outlet of the second dust removal section is in an open state, and the dust outlet is in a closed state. Under the action of the dust reduction component, the dust and fine particles in the second dust removal section are deposited into the dust deposition chamber; when the dust in the dust deposition chamber is deposited to a preset amount and dust cleaning operations are required, the dust reduction component and the clean air outlet are closed, the dust outlet is opened, and the dust deposition chamber is cleaned. The setting of this solution has a good dust reduction effect and is very convenient for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1 to 4 As shown, an embodiment of the present invention provides a dust removal device, which includes a primary dust removal unit 10, a secondary dust removal unit 20 and a dust suction unit 30. The primary dust removal unit 10 includes a first shell 11, the first shell 11 is provided with a material inlet 1101, a first dust removal chamber 1102, a material outlet 1103 and a dust outlet 1104, the material outlet 1103 is connected to the bottom of the first dust removal chamber 1102, and the material inlet 1101 and the dust outlet 1104 are respectively connected to the top of the first dust removal chamber 1102; the secondary dust removal unit 20 includes a second shell 21 and a dust reduction assembly 22, the second shell 21 is provided with a dust inlet 2101, a second dust removal chamber 2102, a dust deposition chamber 2103 and a dust outlet 2104 that are connected in sequence, the dust inlet 2101 is connected to the dust outlet 1104, and the second shell 21 is also provided with a clean air outlet 210 5. The clean air outlet 2105 is connected to the top of the second dust removal chamber 2102; the dust reduction component 22 is arranged in the secondary dust removal section 20, and the dust reduction component 22 deposits the dust in the secondary dust removal section 20 into the dust deposition chamber 2103; the dust suction section 30 is arranged in the primary dust removal section 10, and the dust suction section 30 sucks the dust in the first dust removal chamber 1102 into the secondary dust removal section 20; the secondary dust removal section 20 has a relatively set dust removal state and a dust cleaning state. When the secondary dust removal section 20 is in the dust removal state, the dust outlet 2104 is closed and the clean air outlet 2105 is opened; when the secondary dust removal section 20 is in the dust cleaning state, the dust outlet 2104 is opened and the clean air outlet 2105 is closed.

[0038] The technical scheme of the present application facilitates dust reduction in the coal conveying process, and the convenience of dust cleaning is high.Specifically, when dust removal is required during the coal conveying process, the coal conveying device conveys coal into the first shell 11 through the material inlet 1101, and under the action of gravity, the large coal falls through the material outlet 1103 to the lower side of the first dust removal part 10 for the next processing link, and under the action of the dust suction part 30, fine particles and dust are sucked into the second dust removal part 20, at this time, the clean air outlet 2105 of the second dust removal part 20 is in an open state, and the dust outlet 2104 is in a closed state, and under the action of the dust reduction assembly 22, the dust and fine particles in the second dust removal part 20 are deposited into the dust deposition cavity 2103; when the dust in the dust deposition cavity 2103 is deposited to a preset amount, dust cleaning is required, the dust reduction assembly 22 and the clean air outlet 2105 are closed, and the dust outlet 2104 is opened, and the dust deposition cavity 2103 is subjected to dust cleaning. The present scheme has good dust reduction effect and high convenience of dust cleaning.

[0039] In an embodiment of the present scheme, the first dust removal part 10 further comprises a flexible shielding part 12, which is annularly arranged at the material outlet 1103.

[0040] In an embodiment of the present scheme, the second dust removal part 20 is a cyclone dust reduction machine, and the dust reduction assembly 22 is a cyclone dust reduction part.

[0041] Further, the dust removal device further comprises a dust collection part 40, which has an opening 401 and a dust collection cavity 402 in communication with each other, when the second dust removal part 20 is in the dust cleaning state, the dust outlet 2104 is in communication with the opening 401. When the second dust removal part 20 is switched to the dust cleaning state, the dust in the second dust removal part 20 is directly guided to the opening 401 of the dust collection part 40 through the dust outlet 2104, and then enters the dust collection cavity 402. In this way, the dust discharged from the second dust removal part 20 can be collected in time and effectively, avoiding secondary diffusion of the dust and reducing the impact on the surrounding environment.

[0042] In an embodiment of the present scheme, the dust deposition cavity 2103 is located below the second dust removal cavity 2102, and the dust outlet 2104 is in communication with the bottom of the dust deposition cavity 2103. The dust collection part 40 is located below the second dust removal part 20, and the opening 401 is arranged at the top of the dust collection part 40. When the second dust removal part 20 is in the dust cleaning state, the dust outlet 2104 is located directly above the opening, and in this way, the dust in the second dust removal part 20 can directly fall into the dust collection part 40, improving the convenience of the dust collection part 40 in collecting dust.

[0043] Furthermore, there are multiple dust outlets 1104 and secondary dust removal units 20, respectively, and one secondary dust removal unit 20 is correspondingly provided at each dust outlet 1104. Such a setting can improve the dust removal effect of the secondary dust removal unit 20.

[0044] In an embodiment of this solution, the relative position of the dust collection unit 40 and multiple secondary dust removal units 20 is adjustable, and the opening 401 of the dust collection unit 40 can be selectively connected to the dust discharge port 2104 of any secondary dust removal unit 20. This arrangement allows one secondary dust removal unit 20 to be cleaned while the other secondary dust removal units 20 continue to perform dust removal operations. This arrangement avoids the need to stop the entire system when cleaning one secondary dust removal unit 20, reducing downtime. Furthermore, the provision of a single dust collection unit 40 can reduce the footprint of the device.

[0045] Furthermore, multiple secondary dust removal units 20 are spaced apart and distributed around the outer periphery of the first housing 11 along the circumference of the first housing 11, and the dust collection unit 40 is located around the outer periphery of the first housing 11. This arrangement ensures uniformity in the dust and fine particles adsorbed in each secondary dust removal unit 20.

[0046] Specifically, the first shell 11 includes a main body 111 and a rotating part 112. The rotating part 112 is rotatably arranged on the top of the main body 111. A first dust removal chamber 1102 is formed between the rotating part 112 and the main body 111. A material outlet 1103 is formed at the bottom of the main body 111. A plurality of dust outlets 1104 are arranged on the side wall of the rotating part 112 at intervals along the circumference of the rotating part 112. When a secondary dust removal section 20 needs to be cleaned, the rotating part 112 rotates until the secondary dust removal section 20 that needs to be cleaned is located above the dust collection section 40. The rotation of the rotating part 112 is stopped, and the dust reduction assembly 22 of the secondary dust removal section 20 that needs to be cleaned stops the dust reduction operation and performs the cleaning operation; the remaining secondary dust removal sections 20 continue the dust removal operation. This arrangement has a simple structure and is easy to operate. In the embodiment of this solution, the main body 111 is a cylindrical structure with openings at both the top and bottom, and the rotating portion 112 is a cylindrical structure with an opening at the bottom and a closed top. The bottom of the rotating portion 112 is in sealed communication with the top of the main body 111. This arrangement makes the structural design of the first housing 11 more reasonable and saves space.

[0047] Furthermore, a spiral groove is provided on the inner side wall of the main body 111 , and the provision of the spiral groove can facilitate the falling of materials.

[0048] In some embodiments of the present solution, the primary dust removal section 10 further includes an induced draft tube, and the dust suction section 30 is disposed in the induced draft tube to suck the dust in the first shell 11 into the secondary dust removal section 20 .

[0049] In an embodiment of this solution, the dust removal device further includes a first solenoid valve 211 and a second solenoid valve 212. The first solenoid valve 211 is disposed at the dust outlet 2104 of the secondary dust removal section 20 and is used to adjust the opening of the dust outlet 2104. The second solenoid valve 212 is disposed at the clean air outlet 2105 of the secondary dust removal section 20 and is used to adjust the opening of the clean air outlet 2105. A control system is electrically connected to the first solenoid valve 211 and the second solenoid valve 212, respectively, to control the operating states of the first solenoid valve 211 and the second solenoid valve 212, respectively. The control system is electrically connected to the first solenoid valve 211 and the second solenoid valve 212, respectively, to adjust the openings of the dust outlet 2104 and the clean air outlet 2105, respectively. This configuration enables the secondary dust removal section 20 to automatically switch between a dust cleaning state and a dust removal state.

[0050] Furthermore, the control system is electrically connected to the dust suppression assembly 22. When the first solenoid valve 211 of the secondary dust removal unit 20 closes the dust discharge port 2104 and the second solenoid valve 212 opens the clean air discharge port 2105, the control system controls the corresponding dust suppression assembly 22 to perform dust suppression operations. When the first solenoid valve 211 of the secondary dust removal unit 20 opens the dust discharge port 2104 and the second solenoid valve 212 closes the clean air discharge port 2105, the control system controls the corresponding dust suppression assembly to stop operating. This configuration improves the automation level of the device.

[0051] Furthermore, the dust removal device also includes a first sensor 51 and a second sensor 52. The first sensor 51 is disposed on the dust collection section 40. Each secondary dust removal section 20 is provided with a second sensor 52, which cooperates with the first sensor 51. The control system is electrically connected to the second sensor 52. When the first sensor 51 senses the second sensor 52, the control system controls the first solenoid valve 211 of the corresponding secondary dust removal section 20 to open the dust discharge port 2104, and controls the second solenoid valve 212 of the corresponding secondary dust removal section 20 to close the clean air discharge port 2105. The arrangement of the first and second sensors 51, 52 enables determination of whether a secondary dust removal section 20 is located directly above the dust collection section 40. When the first sensor 51 senses the second sensor 52, the control system controls the corresponding secondary dust removal section 20 to switch from a dust removal mode to a dust cleaning mode. This arrangement further enhances the automation level of the device.

[0052] Specifically, the first sensing element 51 is disposed at the top of the dust collection section 40, and the second sensing element 52 is disposed at the bottom of the secondary dust removal section 20. When the projection of the second sensing element 52 is located on the first sensing element 51 along the height direction, the first sensing element 51 senses the signal of the second sensing element 52. This arrangement ensures the accuracy of the sensing between the first sensing element 51 and the second sensing element 52.

[0053] The dust removal device further includes a dust flow detector, located at the dust outlet 2104. The dust flow detector is used to detect the amount of dust discharged at the dust outlet 2104. The dust flow detector is electrically connected to a control system. When the dust discharge reaches zero, the control system controls the first solenoid valve 211 of the corresponding secondary dust removal unit 20 to close the dust outlet 2104 and the second solenoid valve 212 of the corresponding secondary dust removal unit 20 to open the clean air outlet 2105. When dust cleaning begins and dust within the secondary dust removal unit 20 is discharged into the dust collection unit 40 through the dust outlet 2104, the dust flow detector continuously monitors changes in the dust level during the discharge process. When the dust flow detector detects that the dust discharge at the dust outlet 2104 is zero, this generally indicates that the dust within the secondary dust removal unit 20 has been substantially discharged and the secondary dust removal unit 20 has achieved the predetermined cleaning target. At this point, the control system receives a signal from the dust flow detector and immediately responds by adjusting the corresponding first and second solenoid valves 211 and 212. The control system controls the first solenoid valve 211 to close the dust outlet 2104, preventing air from flowing backwards. Simultaneously, the control system opens the second solenoid valve 212, which opens the clean air outlet 2105, allowing filtered clean air to escape. The secondary dust removal unit 20 then returns to the dust removal state. This configuration allows the secondary dust removal unit 20 to promptly switch back to the dust removal state after completing its dust removal operation, improving the operational continuity of the device.

[0054] In an embodiment of the present invention, the dust removal device further comprises an exhaust pipe 60, which comprises an exhaust duct, an exhaust port 601, and a connecting port 602. The exhaust port 601 is connected to the exhaust duct, and a plurality of connecting ports 602 are provided. The plurality of connecting ports 602 are arranged along the distribution direction of the plurality of secondary dust removal sections 20. The positions of the plurality of secondary dust removal sections 20 relative to the exhaust pipe 60 are adjustable. When one of the secondary dust removal sections 20 is in the dust cleaning state, the clean air outlets 2105 of the remaining secondary dust removal sections 20 are respectively connected to a connecting port 602. In an embodiment of the present invention, the exhaust pipe 60 is an arc-shaped tubular structure. The exhaust pipe 60 extends along the circumference of the first housing 11. The exhaust pipe 60 is located above the plurality of secondary dust removal sections 20, and the connecting port 602 is provided at the bottom of the exhaust pipe 60. The above arrangement can ensure that the plurality of connecting ports 602 can be flexibly connected to the plurality of secondary dust removal sections 20 during the process of the rotating portion 112 driving the plurality of secondary dust removal sections 20 to rotate. Furthermore, the above arrangement has a simple structure and is easy to operate.

[0055] Furthermore, the dust removal device also includes an exhaust component 70, which is disposed on the exhaust pipe 60 and is used to exhaust air out of the exhaust port 601. The exhaust component 70 is provided to improve the air circulation effect within the secondary dust removal unit 20 when the secondary dust removal unit 20 is in the dust removal state, so that the filtered clean air can be discharged to the external environment more quickly, thereby reducing the retention time of the filtered air in the exhaust pipe 60.

[0056] In the embodiment of this solution, a filter unit is further included, and a filter unit is provided at the clean air outlet 2105 of each secondary dust removal unit 20. By providing the filter unit at the clean air outlet 2105, it is possible to further remove fine dust particles that may remain in the clean air discharged by the secondary dust removal unit 20, further improving the air purification effect.
