DETAILED DESCRIPTION

[0031] The following will be combined with the 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 10 The present invention provides a technical solution: a concrete dust treatment device, comprising a main treatment bin 1, a connecting pipe 4 and a secondary treatment bin 2, a dust collecting electrode plate for absorbing dust is installed on the bottom surface of the inner wall of the secondary treatment bin 2, the main treatment bin 1 is connected to the secondary treatment bin 2 through the connecting pipe 4, a feed pipe 3 is fixedly installed on the surface of the main treatment bin 1, and an air outlet pipe 5 is fixedly connected to the surface of the secondary treatment bin 2.

[0033] The inner wall of the main processing bin 1 is provided with a metal filter screen 6, and the auxiliary processing bin 2 is provided with a collection component for electrostatic adsorption of concrete dust. The bottom ends of the main processing bin 1 and the auxiliary processing bin 2 are both provided with a discharge port 7, and the bottom ends of the main processing bin 1 and the auxiliary processing bin 2 are both fixedly installed with a vibration device 8, and the vibration device 8 can be a vibration motor. The dust first enters the main processing bin 1 through the feed pipe 3, and is filtered by the metal filter screen 6 provided in the main processing bin 1. The dust with a larger particle size falls through the discharge port 7 provided at the bottom of the main processing bin 1 and is collected after passing through the metal filter screen. The dust on the net 6 passes through the connecting pipe 4 and enters the auxiliary treatment bin 2. The dust entering the auxiliary treatment bin 2 falls after being electrostatically adsorbed by the collecting component, and then is adsorbed by the dust collecting electrode plate installed on the inner wall of the auxiliary treatment bin 2. Subsequently, the vibration device 8 at the bottom of the auxiliary treatment bin 2 is turned on to shake off the concrete dust adsorbed on the surface of the dust collecting electrode plate, and finally is discharged and collected through the discharge port 7 set at the bottom of the auxiliary treatment bin 2. Through the above process, the concrete dust can be quickly and concentratedly dropped, and the collection efficiency of the concrete dust is greatly improved, thereby speeding up the efficiency of concrete production.

[0034] In order to adsorb and collect the concrete dust in the auxiliary treatment bin 2, further, the collecting component includes an electrode mounting rotating plate 9 and a polygonal rotating plate 12. The surface of the auxiliary treatment bin 2 is provided with a mounting hole for the power cord of the electrode mounting rotating plate 9 to pass through. The side of the electrode mounting rotating plate 9 is connected to a support plate 10 by fixed-axis rotation. The support plate 10 is fixedly connected to the upper end of the inner wall of the auxiliary treatment bin 2. The surface of the electrode mounting rotating plate 9 is provided with a plurality of openings. The electrode mounting rotating plate 9 is connected to a plurality of metal adsorption columns 11 through the openings. It is connected to the metal adsorption column 11 through a metal bearing for fixed-axis rotation. After the electrode mounting rotating plate 9 is energized, the metal adsorption column 11 is energized through the conductivity of the bearing. A plurality of through holes are provided at the end of the polygonal rotating plate 12. The polygonal rotating plate 12 is connected to the plurality of metal adsorption columns 11 through the through holes for fixed-axis rotation. It also includes a driving component for driving the metal adsorption column 11 to perform a circular motion. By connecting the power supply to the electrode mounting rotating plate 9, the metal adsorption column 11 is energized, so that the concrete dust in the auxiliary treatment bin 2 is adsorbed and collected by the metal adsorption column 11.

[0035] In order to speed up the dust collection efficiency of concrete dust, further, the driving component includes a motor 13, the motor 13 is fixedly installed on the top of the inner wall of the auxiliary processing bin 2, the bottom surface of the output shaft of the motor 13 is fixedly connected with a rotating shaft 14, the bottom surface of the rotating shaft 14 is fixedly connected with a rotating plate 15, the end of the rotating plate 15 away from the rotating shaft 14 is hinged with a swing plate 17, the shaft arm of the swing plate 17 is slidably connected with a sliding sleeve 18, the surface of the sliding sleeve 18 is fixedly connected with a rotating shaft 3 19, the top of the rotating shaft 3 19 is fixedly connected to the top of the inner wall of the auxiliary processing bin 2, the end of the swing plate 17 is fixedly connected with a U-shaped plate 20, the motor 13 is started, the rotating shaft 14 is rotated by the rotation of the output shaft of the motor 13, and then the rotating plate 15 is driven to rotate with the rotating shaft 14 as the axis, such as Figure 6 In the direction shown, the U-shaped plate 20 is facing the connecting pipe 4, and the metal adsorption column 11 at the position of the U-shaped plate 20 first adsorbs the dust discharged from the connecting pipe 4, thereby adsorbing the most dust. Through the above process, the rotating plate 15 rotates, so that the swing plate 17 is limited by the sliding sleeve 18 and the rotating shaft 3 19, and at the same time, the U-shaped plate 20 is driven to move in the direction away from the sliding sleeve 18, and as the U-shaped plate 20 rotates clockwise, the gear 22 is pushed to make the multi-angle rotating plate 12 and the electrode mounting rotating plate 9 rotate clockwise, so that the rotating metal adsorption column 11 simultaneously performs clockwise circular motion, thereby moving it in the direction away from the connecting pipe 4, so that the subsequent metal adsorption column 11 moves to the outlet toward the connecting pipe 4 to adsorb the dust. At this time, as shown in the figure, the U-shaped plate 20 rotates clockwise, and the gear 22 is pushed to make the multi-angle rotating plate 12 and the electrode mounting rotating plate 9 rotate clockwise, so that the rotating metal adsorption column 11 simultaneously performs clockwise circular motion, and then moves it in the direction away from the connecting pipe 4, so that the subsequent metal adsorption column 11 moves to the outlet toward the connecting pipe 4 to adsorb the dust. Figure 7 In the state shown, as the rotating plate 15 continues to rotate, the U-shaped plate 20 moves toward the sliding sleeve 18, and then after separating from the gear 22, it rotates counterclockwise and moves away from the sliding sleeve 18, so that the device returns to the state shown in FIG. Figure 6 In the state shown, repeating the above process can make multiple metal adsorption columns 11 rotate in a circle while rotating, driving multiple metal adsorption columns 11 to evenly adsorb dust, greatly accelerating the dust collection efficiency of concrete dust.

[0036] In order to make the adsorption effect of the metal adsorption column 11 better, it further includes a rotating component that drives the metal adsorption column 11 to rotate. The rotating component includes a tooth row 21, and the tooth row 21 is fixedly connected to the inner wall of the U-shaped plate 20. The top of the metal adsorption column 11 is fixedly sleeved with a gear 22. When the U-shaped plate 20 moves in the direction away from the sliding sleeve 18, the tooth row 21 engages with the gear 22. At this time, the U-shaped plate 20 drives the paddle plate 23 to abut against the inclined surface of the inclined block 27, so that the inclined block 27 squeezes the spring 28 to slide, so that the inclined block 27 does not hinder the continued movement of the paddle plate 23. The tooth row 21 moves with the U-shaped plate 20 while causing the gear 22 to rotate, thereby driving the metal adsorption column 11 to rotate, so that the surface of the metal adsorption column 11 can evenly adsorb the concrete dust sprayed from the connecting pipe 4, so that the adsorption effect of the metal adsorption column 11 is better.

[0037] Furthermore, it also includes a plurality of vibration components for knocking and removing dust from any metal adsorption column 11 after it passes through the connecting pipe 4. The vibration components include a plurality of paddles 23 fixedly connected to the inner wall of the U-shaped plate 20. An operating cavity 24 is provided on the surface of the polygonal rotating plate 12. A slider 25 is slidably connected to the inner wall of the operating cavity 24. A spring 31 is fixedly connected to the surface of the slider 25 and the inner wall of the operating cavity 24. A slide groove 26 is provided on the surface of the slider 25. An inclined block 27 is slidably connected to the inner wall of the slide groove 26. A spring 28 is fixedly connected to the bottom surface of the inclined block 27 and the inner wall of the slide groove 26. The surface of the slider 25 A striker 29 is fixedly connected, and the surface of the striker 29 slides along the inner wall of the operating chamber 24. A protective cover 30 is fixedly connected to the end of the striker 29. The U-shaped plate 20 moves in a direction away from the sliding sleeve 18, so that the tooth row 21 is meshed with the gear 22. At this time, the U-shaped plate 20 drives the paddle plate 23 to press the inclined surface of the inclined block 27, driving the inclined block 27 to squeeze the spring 28 and move downward, so that the paddle plate 23 continues to move over the inclined block 27, and the U-shaped plate 20 moves in a direction close to the sliding sleeve 18, and then separates from the gear 22, and then rotates counterclockwise and moves in a direction away from the sliding sleeve 18, thereby restoring the Figure 6 In the state shown, the U-shaped plate 20 is as Figure 7 In the process of moving toward the sliding sleeve 18 in the state shown, the paddle plate 23 moves synchronously and abuts against the flat surface of the inclined block 27, so that the slider 25 squeezes the spring 1 31 to slide. When the slider 25 moves to drive the inclined surface of the inclined block 27 to abut against the groove wall of the operating chamber 24, the inclined block 27 squeezes the spring 28 to move downward and separate from the paddle plate 23. At this moment, the elastic force of the spring 1 31 is released, so that the impact rod 29 collides with the metal adsorption column 11, so that the dust adsorbed on its surface is shaken off, and the subsequent collection process is carried out, which significantly accelerates the dust collection efficiency of concrete dust.

[0038] In order to increase the surface of the metal adsorption column 11 and improve the single dust adsorption capacity of the metal adsorption column 11, further, the surface of any metal adsorption column 11 is configured to be uneven.

[0039] Working principle: When the concrete dust treatment device is used, the operator first passes the dust into the main treatment bin 1 through the feed pipe 3. After preliminary filtration by the metal filter 6 arranged in the main treatment bin 1, the dust with larger particle size falls through the discharge port 7 arranged at the bottom of the main treatment bin 1 for collection, and the dust passing through the metal filter 6 enters the auxiliary treatment bin 2 through the connecting pipe 4.

[0040] The electrode installation rotating plate 9 is started, so that the multiple metal adsorption columns 11 are energized to adsorb the concrete dust sprayed from the connecting pipe 4, and the motor 13 is started. The output shaft of the motor 13 rotates to drive the rotating shaft 14 to rotate, thereby driving the rotating plate 15 to rotate with the rotating shaft 14 as the axis. Figure 6 The U-shaped plate 20 is moved in the direction shown in the figure. At this time, the position of the U-shaped plate 20 corresponds to the connecting pipe 4, that is, the metal adsorption column 11 at the position of the U-shaped plate 20 adsorbs the maximum amount of dust. Through the rotation process of the above-mentioned rotating plate 15, the swing plate 17 is driven to move in the direction away from the sliding sleeve 18 and the rotating shaft 3 19 under the limit of the sliding sleeve 18 and the rotating shaft 3. While driving the U-shaped plate 20 to rotate clockwise, the U-shaped plate 20 is pushed to move in the direction away from the sliding sleeve 18. Through the process of the U-shaped plate 20 moving in the direction away from the sliding sleeve 18, the tooth row 21 is driven to engage with the gear 22. At the same time, the U-shaped plate 20 drives the paddle plate 23 to press the inclined surface of the inclined block 27, so that the inclined block 27 presses the spring 28 to move downward, and then the paddle plate 23 continues to move over the inclined block 27. The tooth row 21 moves with the U-shaped plate 20 and causes the gear 22 to rotate, thereby causing the metal adsorption column 11 to rotate, so that the surface of the metal adsorption column 11 evenly adsorbs the concrete dust sprayed from the connecting pipe 4, so that the adsorption effect of the metal adsorption column 11 is better.

[0041] At the same time, the U-shaped plate 20 rotates clockwise, pushing the gear 22, so that the polygonal rotating plate 12 drives the electrode installation rotating plate 9 to rotate clockwise, so that the metal adsorption column 11 rotating in the above process performs a clockwise circular motion, thereby moving away from the connecting pipe 4, so that the next metal adsorption column 11 moves to the outlet of the connecting pipe 4 to adsorb dust. At this time, the device moves to Figure 7 In the state shown, as the rotating plate 15 continues to rotate, the U-shaped plate 20 is driven to move in the reverse direction, that is, after the U-shaped plate 20 moves toward the direction close to the sliding sleeve 18 and separates from the gear 22, it rotates counterclockwise and moves away from the sliding sleeve 18, returning to the state shown in FIG. Figure 6 In the state shown, the U-shaped plate 20 is as Figure 7In the process of moving toward the sliding sleeve 18 in the shown state, the paddle plate 23 moves synchronously and abuts the flat surface of the inclined block 27, driving the slider 25 to squeeze the spring 1 31 to slide. When the slider 25 moves to drive the inclined surface of the inclined block 27 to abut against the groove wall of the operating chamber 24, the inclined block 27 presses the spring 28 to move downward and separate from the paddle plate 23. At this time, the elastic force of the spring 1 31 is released instantly, driving the impact rod 29 to hit the metal adsorption column 11, so that the dust adsorbed on the surface is shaken off, and the subsequent collection process is carried out. By repeating the above process, the multi-angle rotating plate 12 can be driven to rotate intermittently clockwise, and the multiple metal adsorption columns 11 can be driven to rotate in a circle while rotating, so that the multiple metal adsorption columns 11 can evenly adsorb dust, which significantly accelerates the dust collection efficiency of concrete dust.

[0042] After the concrete dust is shaken off, it is collected centrally by the dust collecting electrode plate arranged at the bottom of the inner wall of the auxiliary processing bin 2. The vibration device 8 at the bottom of the auxiliary processing bin 2 is started to shake off the concrete dust adsorbed on the dust collecting electrode plate, and the concrete dust is discharged and collected by the discharge port 7 arranged at the bottom of the auxiliary processing bin 2. Through the above process, the concrete dust can be quickly and centrally dropped, and the collection efficiency of the concrete dust is greatly improved, thereby accelerating the efficiency of concrete production.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
