Description

Technical Field

[0001] This utility model relates to the technical field of dust removal equipment for mining, and in particular to a high-efficiency dust removal device for an integrated tunneling and anchoring machine. Background Technology

[0002] The tunneling and anchoring machine is a core piece of equipment in coal mine roadway excavation operations. During processes such as cutting, loading, and anchoring, it generates a large amount of high-concentration dust. This dust not only severely deteriorates the visibility and working environment of the working face, but also poses significant hazards to equipment operation and personnel health. Therefore, an efficient dust removal system has become an indispensable key component of the tunneling and anchoring machine.

[0003] Existing integrated roadheader and anchor machine (TBM) typically uses dust collectors and ventilation ducts for dust control, but lacks an effective airflow control structure. As a result, a large amount of dust at the working face is directly washed into the return air duct, leading to low dust collection efficiency and easy dust diffusion throughout the entire roadway. Therefore, to address these issues, a high-efficiency dust collection device for the TBM can be designed. This device controls the airflow at the working face by installing multiple sets of wall-mounted ventilation ducts, reducing axial airflow and increasing radial airflow, effectively confining dust to the working face area and improving dust collection efficiency. Utility Model Content

[0004] To overcome the problem that existing integrated tunneling and anchoring machines are usually equipped with dust removal fans and air ducts for dust control, but lack an effective airflow control structure, a large amount of dust at the working face is directly washed into the return air duct, resulting in low dust removal efficiency and dust easily spreading throughout the entire roadway.

[0005] The technical solution of this utility model is as follows: a high-efficiency dust removal device for an integrated tunneling and anchoring machine, comprising a fan, a treatment box and a suction assembly. The treatment box and the suction assembly are sequentially and sealed to one end of the fan to form a through-type air passage system. The other end of the fan is sealed to an exhaust box. Both sides of the exhaust box are sealed to multiple sets of wall-mounted air ducts, which are arranged in a uniform matrix. One end of the exhaust box is sealed to an exhaust pipe.

[0006] Preferably, a fan is used to provide negative pressure to the overall dust removal device, thereby sucking up a large amount of dust from the working face through the suction component. The dust-laden airflow is processed inside the treatment box and then discharged through the wall-mounted air duct and exhaust pipe. During operation, the radial air outlet structure of the wall-mounted air duct and the exhaust pipe complete the directional discharge of the purified airflow. The wall-mounted air duct with radial air outlet design can effectively reduce the axial air outlet ratio of the exhaust pipe, forming a stable air curtain barrier at the working face, realizing the effective containment and control of dust in the working area at the working face, thereby significantly improving dust removal efficiency and inhibiting the diffusion and migration of dust to other areas of the roadway.

[0007] As a preferred option, both the exhaust box and the wall-mounted air duct are covered with sound-insulating cotton.

[0008] Preferably, a mounting bracket is fixedly installed inside the treatment box, and a filter screen is fixedly installed between the mounting bracket and the treatment box, with the filter screen set at an angle.

[0009] Preferably, a conveying pipe is fixedly installed inside the treatment box, and multiple sets of nozzles are connected to the periphery of the conveying pipe. The output end of the nozzles is aligned with the filter screen, and the input end of the conveying pipe passes through the treatment box and extends to the outside.

[0010] Preferably, multiple sets of dewatering corrugated plates are fixedly installed between the mounting frame and the treatment box. These multiple sets of dewatering corrugated plates are arranged linearly and located on one side of the filter screen.

[0011] Preferably, the mounting bracket is a hollow structure, with multiple through holes on the upper wall of the mounting bracket, and a drain pipe is connected to one end of the mounting bracket.

[0012] Preferably, the suction assembly includes a connecting box, a movable plate, and leather sidewalls. The connecting box is connected to one end of the processing box, and the movable plate is hinged to the lower end of the connecting box. Two sets of leather sidewalls are fixedly installed between the movable plate and the connecting box.

[0013] The beneficial effects of this utility model are: By using a fan as the negative pressure drive source for the overall dust removal device, the dust-laden airflow at the working face is actively captured through the suction components. After being efficiently purified by the treatment box, the dust-laden airflow is directionally discharged through the radial air outlet structure of the wall-mounted air duct and the exhaust pipe. During operation, the wall-mounted air duct with radial air outlet design can effectively reduce the axial air outlet ratio of the exhaust pipe, forming a stable air curtain barrier at the working face, realizing the effective containment and control of dust in the working area at the working face, thereby significantly improving dust removal efficiency and inhibiting the diffusion and migration of dust to other areas of the roadway.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please see Figure 1 and Figure 4 This utility model provides an embodiment of a high-efficiency dust removal device for an integrated excavator and anchor machine, comprising a fan 1, a processing box 2, and a suction assembly. The processing box 2 and the suction assembly are sequentially and sealed to one end of the fan 1, forming a through-type airflow system. The other end of the fan 1 is sealed to an exhaust box 101. Both sides of the exhaust box 101 are sealed to multiple sets of wall-mounted air ducts 102, which are arranged in a uniform matrix. One end of the exhaust box 101 is sealed to an exhaust pipe 103. By setting the fan 1 to provide negative pressure for the entire dust removal device, the dust is drawn through the suction assembly. A large amount of dust is drawn from the working face. The dust-laden airflow is processed inside the treatment box 2 and then discharged through the wall-mounted air duct 102 and the exhaust pipe 103. During operation, the purified airflow is directionally discharged through the radial air outlet structure of the wall-mounted air duct 102 and the exhaust pipe 103. The wall-mounted air duct 102 with radial air outlet design can effectively reduce the axial air outlet ratio of the exhaust pipe 103, forming a stable air curtain barrier at the working face, realizing the effective containment and control of dust in the working face area, thereby significantly improving dust removal efficiency and inhibiting the diffusion and migration of dust to other areas of the roadway.

[0017] Please see Figure 1 and Figure 2 In this embodiment, the exhaust box 101 and the wall-mounted air duct 102 are both covered with sound insulation cotton. The sound insulation cotton can effectively reduce the noise generated by dust removal operations. The suction assembly includes a connecting box 301, a movable plate 302, and a leather sidewall 303. The connecting box 301 is connected to one end of the processing box 2. The lower end of the connecting box 301 is hinged to the movable plate 302. Two sets of leather sidewalls 303 are fixedly installed between the movable plate 302 and the connecting box 301. The connecting box 301, the movable plate 302, and the leather sidewalls 303 form a complete suction port. The hinged movable plate 302 and the leather sidewalls 303 can flexibly adjust the size of the suction port opening according to the space conditions on site, effectively avoiding the suction port being deformed by pressure when the anchor cutter cuts the top, and ensuring the continuous and stable operation of the dust removal operation.

[0018] Please see Figure 2 and Figure 3 In this embodiment, a mounting frame 201 is fixedly installed inside the processing box 2. A filter screen 202 is fixedly installed between the mounting frame 201 and the processing box 2. The filter screen 202 is inclined. A conveying pipe 203 is fixedly installed inside the processing box 2. Multiple sets of nozzles 204 are connected to the periphery of the conveying pipe 203. The output end of the nozzle 204 is aligned with the filter screen 202. The input end of the conveying pipe 203 passes through the processing box 2 and extends to the outside. Multiple sets of dewatering corrugated plates 205 are also fixedly installed between the mounting frame 201 and the processing box 2. The multiple sets of dewatering corrugated plates 205 are linearly arranged and located on one side of the filter screen 202. The mounting frame 201 is a hollow structure. The upper wall of the mounting frame 201... The surface has multiple sets of through holes 206, and one end of the mounting bracket 201 is connected to a drain pipe 207. The filter screen 202 and the dehydration corrugated plate 205 are installed by setting the mounting bracket 201. When the dust-laden airflow enters the treatment box 2, it first passes through the filter screen 202 to intercept the dust, and then clean water is delivered to the nozzle 204 through the conveying pipe 203 to rinse and clean the filter screen 202. The dust is mixed in the water and discharged through the drain pipe 207. The humid air is dehydrated by the dehydration corrugated plate 205 and then discharged into the exhaust box 101 by the fan 1. The water vapor intercepted by the dehydration corrugated plate 205 is liquefied and enters the interior of the mounting bracket 201 through the through holes 206 and is finally discharged through the drain pipe 207.

[0019] During operation, the connecting box 301, movable plate 302 and leather sidewall 303 form a complete air intake. The hinged movable plate 302 and leather sidewall 303 can flexibly adjust the air intake opening size according to the space conditions on site, effectively avoiding the air intake from being deformed by pressure when the tunneling and anchoring machine cuts the top, and ensuring the continuous and stable operation of dust removal. The blower 1 provides negative pressure to the overall dust removal device, thereby sucking up a large amount of dust from the working face through the suction port. The dust-laden airflow is processed inside the treatment box 2 and then discharged through the wall-mounted air duct 102 and the exhaust pipe 103. During operation, the radial air outlet structure of the wall-mounted air duct 102 and the exhaust pipe 103 are used to complete the directional discharge of the purified airflow. The wall-mounted air duct 102 with radial air outlet design can effectively reduce the axial air outlet ratio of the exhaust pipe 103, forming a stable air curtain barrier at the working face, realizing the effective containment and control of dust in the working area at the working face, thereby significantly improving dust removal efficiency and inhibiting the diffusion and migration of dust to other areas of the roadway. When the dust-laden airflow enters the treatment box 2, it first passes through the filter screen 202 to intercept the dust, and then clean water is delivered to the nozzle 204 through the conveying pipe 203 to rinse and clean the filter screen 202. The dust is then mixed with water and discharged through the drain pipe 207. The humid air is dehydrated by the dehydration corrugated plate 205 and then discharged into the exhaust box 101 by the fan 1. The water vapor intercepted by the dehydration corrugated plate 205 is liquefied and enters the mounting frame 201 through the through hole 206 and is finally discharged through the drain pipe 207.

[0020] Through the above steps, the directional discharge of purified airflow is achieved through the radial air outlet structure of the wall-mounted ventilation duct 102 and the exhaust pipe 103. The wall-mounted ventilation duct 102 with radial air outlet design can effectively reduce the axial air outlet ratio of the exhaust pipe 103, forming a stable air curtain barrier at the working face, realizing the effective containment and control of dust in the working face area, thereby significantly improving dust removal efficiency and inhibiting the spread and migration of dust to other areas of the roadway. This solves the problem that existing integrated tunneling and anchoring machines are usually equipped with dust removal fans 1 and ventilation ducts for dust control, lacking an effective airflow control structure. A large amount of dust at the working face is directly washed into the return air duct, resulting in low dust removal efficiency and dust easily spreading to the entire roadway.

[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
