Description

Technical Field

[0001] This utility model relates to the field of dust control equipment in mines, and more specifically, to a comprehensive dust removal system for ore unloading in ore passes. Background Technology

[0002] With the increasing depth of underground mining, mine operations generally adopt a multi-level, multi-stop operation method. Passes, with their advantages of large transport capacity, high transfer efficiency, convenient operation and management, and simple reliability, occupy an important position in underground mining and serve as crucial channels for transporting ore within the stope. Due to the significant elevation difference during ore discharge, the air inside the pass is rapidly compressed during the descent, generating a powerful dust-laden airflow, which is one of the typical sources of dust pollution in underground metal mines. This dust-laden airflow is discharged through the branch pass openings, causing severe dust pollution in the underground working face and ventilation system, especially respirable dust with a particle size of less than 5μm, which greatly endangers the physical and mental health of workers.

[0003] However, existing integrated dust removal systems for ore pass unloading use negative pressure dust removal followed by wet scrubbing. During wet scrubbing, the high temperature and poor air circulation inside the pass lead to a fixed atomization moisture range, significantly reducing the lifespan of the drive equipment. Furthermore, prolonged atomization can impair visibility within the pass. Additionally, the impact of ore falling against the pass walls or within the pass generates strong airflow, which, under the counter-impact force, carries dust particles upwards, creating dust. The greater the drop in ore distance from the bottom of the pass, the more severe the dust generation from the impact airflow. Therefore, insufficient atomization velocity is insufficient for effective dust removal. Utility Model Content

[0004] To address the problem that existing feeding devices cannot be adjusted to feed steel bars of different lengths and specifications, and can only feed steel bars of fixed lengths, the purpose of this utility model is to provide a comprehensive dust removal system for ore chute unloading.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A comprehensive dust removal system for ore chute unloading includes a servo motor; the output end of the servo motor is movably connected to a connecting column via a bearing, the output end of the servo motor passes through the connecting column and is fixedly connected to several fan blades via a coupling, the fan blades being S-shaped, an outer ring is provided on the outer side of the fan blades, and a spray dust removal mechanism is fixedly connected to the bottom side of the outer ring, the output of the servo motor is fixedly connected to a lighting adjustment mechanism, and two obliquely symmetrical lighting lamps are fixedly connected to the surface of the outer ring.

[0007] Optionally, the spray dust removal mechanism includes a heat dissipation pipe, a diversion pipe, a conveying pipe, an annular pipe, and mist spray heads. The diversion pipe is fixedly connected to the bottom end of the heat dissipation pipe. The diversion pipe is annular, and the annular pipe is fixedly connected to the end of the diversion pipe away from the heat dissipation pipe. There are two conveying pipes, and both sides are fixedly connected to the diversion pipe. The annular pipe is fixedly connected to the bottom end of the conveying pipe. There are several mist spray heads arranged in a ring array and fixedly connected to the bottom side of the annular pipe.

[0008] Optionally, the connection points of the heat dissipation pipe, the diversion pipe, the delivery pipe, the annular pipe, and the mist spray head are all interconnected. The heat dissipation pipe is in a spiral upward shape and is sleeved on the outside of the servo motor.

[0009] Optionally, the diverter is fixedly connected to the outside of the connecting column, the conveying pipe is J-shaped, and the bend of the conveying pipe is adapted to the thickness of the outer ring, and the outer ring is located inside the opposite sides of the two conveying pipes.

[0010] Optionally, the annular tube has the same diameter as the outer ring, and the annular tube is fixedly connected to the bottom end of the outer side.

[0011] Optionally, the lighting adjustment mechanism includes a track ring, a connecting strip, a lighting tube, and a sliding strip. The surface of the track ring is provided with a set of symmetrical connecting grooves, and the connecting grooves are annular. The sliding strips are movably connected to the inside of the connecting grooves, the connecting strips are fixedly connected to one end of the sliding strips, and the lighting tubes are fixedly connected to the end of the connecting strips away from the connecting grooves.

[0012] Optionally, the lighting adjustment mechanism further includes a sleeve block, a return spring, and an adjustment bar. The return spring is fixedly connected to the inside of the sleeve block, and the front end of the sleeve block is arc-shaped. The adjustment bar is fixedly connected to the output end of the servo motor, and the adjustment bar is arc-shaped near the arc-shaped end of the sleeve block.

[0013] Optionally, the sleeve is fitted onto the end of the sliding bar away from the connecting bar, and the other end of the return spring is fixedly connected to one end of the sliding bar. The adjusting bar and the sleeve are both located inside the track ring, and the end of the sleeve near the sliding bar is adapted to the connecting groove.

[0014] Compared with the prior art, the technical solution provided by this utility model has at least the following beneficial effects:

[0015] In the above scheme, by setting up a spray dust removal mechanism, an external booster and water pipes are connected to the heat dissipation pipes. At this time, the pressurized dust removal water passes through the heat dissipation pipes, the diversion pipes, the delivery pipes and the annular pipes in sequence until it is sprayed out in the form of mist spray head. At this time, the servo motor drives the fan blades to rotate, and the fan blades generate airflow to blow the atomized water into the chute. This helps to expand the dust removal range and enhance the heat dissipation effect of the drive equipment. It avoids high temperature and poor airflow in the well, which would reduce the service life of the drive equipment and limit the dust removal range.

[0016] By setting up a lighting adjustment mechanism, the servo motor first drives the adjustment bar to rotate counterclockwise. At this time, the adjustment bar rotates to one end of the sleeve block, and its adjustment bar and the arc end of the sleeve block are in opposite directions. Then, the adjustment bar pushes the sleeve block, causing its sliding bar to drive the connecting bar to move to one side. At the same time, the lighting tube and the lighting lamp move away from each other. When the servo motor rotates clockwise, the adjustment bar and the arc end of the sleeve block are opposite each other. At this time, the sleeve block, which is squeezed by the adjustment bar, pushes inward and the reset spring is squeezed and contracted, so that the adjustment bar can pass smoothly through the sleeve block. This is beneficial to adjust the lighting range according to the visibility in the chute and ensure that the situation inside the chute is clear. Attached Figure Description

[0034] like Figures 1 to 4 As shown in the figure, this utility model embodiment provides a comprehensive dust removal system for ore chute unloading, including a servo motor 1. The output end of the servo motor 1 is movably connected to a connecting column 2 via a bearing. The output end of the servo motor 1 passes through the connecting column 2 and is fixedly connected to several fan blades 3 via a coupling. The fan blades 3 are S-shaped. An outer ring 4 is provided on the outer side of the fan blades 3, and a spray dust removal mechanism 5 is fixedly connected to the bottom side of the outer ring 4. The output of the servo motor 1 is fixedly connected to a lighting adjustment mechanism 6. Two obliquely symmetrical lighting lamps 7 are fixedly connected to the surface of the outer ring 4.

[0035] The spray dust removal mechanism 5 includes a heat dissipation pipe 501, a diversion pipe 502, a conveying pipe 503, an annular pipe 504, and mist spray heads 505. The diversion pipe 502 is fixedly connected to the bottom end of the heat dissipation pipe 501. The diversion pipe 502 is annular, and the annular pipe 504 is fixedly connected to the end of the diversion pipe 502 away from the heat dissipation pipe 501. There are two conveying pipes 503, and both sides are fixedly connected to the diversion pipe 502. The annular pipe 504 is fixedly connected to the bottom end of the conveying pipe 503. Several mist spray heads 505 are arranged in a annular array and fixedly connected to the annular pipe 501. On the bottom side of 4, the connection points of the heat dissipation pipe 501, the diversion pipe 502, the delivery pipe 503, the annular pipe 504, and the mist spray head 505 are all interconnected. The heat dissipation pipe 501 is spirally rising and is sleeved on the outside of the servo motor 1. The diversion pipe 502 is fixedly connected to the outside of the connecting post 2. The delivery pipe 503 is J-shaped and the bend of the delivery pipe 503 is adapted to the thickness of the outer ring 4. The outer ring 4 is located inside the opposite sides of the two delivery pipes 503. The annular pipe 504 has the same diameter as the outer ring 4 and is fixedly connected to the bottom of the outer side.

[0036] The external booster and water pipe are connected to the heat dissipation pipe 501. At this time, the pressurized dust removal water passes through the heat dissipation pipe 501, the diversion pipe 502, the delivery pipe 503 and the annular pipe 504 in sequence until it is sprayed out in the form of mist spray head 505. At this time, the servo motor 1 drives the fan blade 3 to rotate. The fan blade 3 generates airflow to blow the atomized water into the chute, which helps to expand the dust removal range and enhance the heat dissipation effect of the drive equipment. This avoids high temperature and poor airflow in the well, which would reduce the service life of the drive equipment and limit the dust removal range.

[0037] The lighting adjustment mechanism 6 includes a track ring 601, a connecting strip 602, a lighting tube 603, and a sliding strip 604. The surface of the track ring 601 has a set of symmetrical connecting grooves 8, and the connecting grooves 8 are annular. The sliding strips 604 are movably connected to the inside of the connecting grooves 8. The connecting strip 602 is fixedly connected to one end of the sliding strip 604. The lighting tubes 603 are fixedly connected to the ends of the connecting strips 602 away from the connecting grooves 8. The lighting adjustment mechanism 6 also includes a sleeve block 605, a return spring 606, and an adjusting strip 607. The positioning spring 606 is fixedly connected to the inside of the sleeve block 605, and the front end of the sleeve block 605 is arc-shaped. The adjusting bar 607 is fixedly connected to the output end of the servo motor 1, and the adjusting bar 607 is arc-shaped near the arc end of the sleeve block 605. The sleeve block 605 is sleeved on the end of the sliding bar 604 away from the connecting bar 602, and the other end of the return spring 606 is fixedly connected to one end of the sliding bar 604. The adjusting bar 607 and the sleeve block 605 are both located inside the track ring 601, and the end of the sleeve block 605 near the sliding bar 604 is adapted to the connecting groove 8.

[0038] The servo motor 1 drives the adjusting bar 607 to rotate counterclockwise. At this time, the adjusting bar 607 rotates to one end of the sleeve block 605, and the arc-shaped end of the adjusting bar 607 and the sleeve block 605 are in opposite directions. Then, the adjusting bar 607 pushes the sleeve block 605, causing its sliding bar 604 to drive the connecting bar 602 to one side. At the same time, the lighting tube 603 and the lighting lamp 7 move away from each other. When the servo motor 1 rotates clockwise, the adjusting bar 607 and the arc-shaped end of the sleeve block 605 are opposite each other. At this time, the sleeve block 605 is pushed inward by the adjusting bar 607, and the return spring 606 is squeezed and contracted, so that the adjusting bar 607 can pass smoothly through the sleeve block 605. This is beneficial to adjust the lighting range according to the visibility in the chute and ensure that the situation inside the chute is clear.

[0039] The working process of the technical solution provided by this utility model is as follows:

[0040] When this application is in use, the external booster and water pipe are connected to the heat dissipation pipe 501, and the negative pressure dust collection equipment is started simultaneously. At this time, the pressurized dust removal water passes through the heat dissipation pipe 501, the diversion pipe 502, the conveying pipe 503, and the annular pipe 504 in sequence until it is sprayed out in atomized form from the mist spray head 505. At this time, the servo motor 1 drives the fan blade 3 to rotate, and the fan blade 3 generates airflow to blow the atomized water into the chute. When the servo motor 1 drives the fan blade 3 to rotate clockwise, the adjusting bar 607 is opposite to the arc-shaped end of the sleeve block 605. At this time, the adjusting bar 607 is subjected to the adjustment bar 607. The compression sleeve 605 pushes the return spring 606 inward to compress and shrink, allowing the adjusting strip 607 to pass smoothly through the sleeve 605. When it is necessary to adjust the lighting in the well, the general servo motor 1 drives the adjusting strip 607 to rotate counterclockwise. At this time, the adjusting strip 607 rotates to one end of the sleeve 605, and the adjusting strip 607 and the arc end of the sleeve 605 are in opposite directions. Then, the adjusting strip 607 pushes the sleeve 605 so that its sliding strip 604 drives the connecting strip 602 to move to one side. At the same time, the lighting tube 603 and the lighting lamp 7 move away from each other to increase the lighting area.
