Description

Technical Field

[0001] This application relates to the technical field of concrete manufacturing equipment, and in particular to a dust collector for concrete production. Background Technology

[0002] Dust pollution is a significant problem in concrete production. To address this issue, dust collectors are typically used to collect and treat the dust generated during concrete production.

[0003] In related technologies, reference can be made to Chinese utility model patent CN216856184U, which discloses a dust collector for concrete production, belonging to the field of concrete production technology. It solves the problem that existing dust collectors accumulate a large amount of dust inside after a period of operation, making cleaning inconvenient and resulting in poor dust removal efficiency. This dust collector for concrete production includes a dust collection box, with support legs fixed around the bottom of the box. An air inlet pipe is connected to the left side of the top of the dust collection box, and an exhaust pipe is connected to the right side of the top of the dust collection box. A fan is installed outside the exhaust pipe. A motor is fixed to the back of the dust collection box, and the motor's output shaft passes through the dust collection box and is fixed to a rotating paddle. Support rods are fixed to both sides of the top of the dust collection box, and a fixing plate is fixed to the top of the support rods. A water tank is connected inside the fixing plate, and a water supply pipe is connected to the bottom of the water tank, passing through the dust collection box and extending into its interior.

[0004] However, in actual operation, when water is supplied to the dust collector through the water pipe, the water is dispersed and flung out by the rotating paddle to form a water mist. This water mist easily clumps up and adheres to the inner wall of the dust collector after it comes into contact with the dust. This not only fails to clean the inner wall of the dust collector, but also causes a lot of difficult-to-remove dust clumps to adhere to the inner wall of the dust collector over time, causing blockages and other adverse effects on the dust removal operation of the dust collector. Utility Model Content

[0005] In order to reduce the probability of dust accumulating on the inner wall of the dust collector, this application provides a dust collector for concrete production.

[0006] This application provides a dust collector for concrete production, which adopts the following technical solution:

[0007] A dust collector for concrete production includes a frame and a dust collection box mounted on the frame. The frame is equipped with a cleaning device for cleaning the inner wall of the dust collection box. The cleaning device includes:

[0008] A cleaning block, which is slidably disposed on the dust collector along the inner wall of the dust collector;

[0009] A cleaning scraper, which is rotatably mounted on a cleaning block;

[0010] A rotating mechanism is provided on the cleaning block and is used to drive the cleaning scraper to rotate. The cleaning scraper contacts the inner wall of the dust collection box under the action of the rotating mechanism.

[0011] A drive mechanism is provided on the dust collection box and is used to drive the cleaning block to move along the inner wall of the dust collection box.

[0012] By adopting the above technical solution, a rotating mechanism is used to rotate the cleaning scraper on the cleaning block, causing the scraper to come into contact with the inner wall of the dust collector. Then, a drive mechanism is used to drive the cleaning block to move along the inner wall of the dust collector. The movement of the cleaning block drives the cleaning scraper to move, and the scraper scrapes off the dust clumps adhering to the inner wall of the dust collector, thus completing the cleaning work of the inner wall of the dust collector. This reduces the probability that the dust clumps accumulated on the inner wall of the dust collector will adversely affect the subsequent dust discharge work of the dust collector. After cleaning, the rotating mechanism rotates the cleaning scraper to disengage from the inner wall of the dust collector, and then the drive mechanism drives the cleaning block to move back to its original position. The entire workflow is efficient and fast.

[0013] Optionally, the rotating mechanism includes:

[0014] A rotating torsion spring is provided on the cleaning block and connected to the cleaning scraper. The cleaning scraper is disengaged from the inner wall of the dust collection box under the action of the rotating torsion spring.

[0015] Rotate the lever, which is vertically slidably mounted on the cleaning block;

[0016] A movable component is disposed on the cleaning block and is used to drive a rotating lever to move. Under the action of the movable component, the rotating lever abuts against the cleaning scraper and drives the cleaning scraper to abut against the inner wall of the dust collection box.

[0017] By adopting the above technical solution, under normal circumstances, the cleaning scraper is fixed on the cleaning block and detached from the inner wall of the dust collector under the action of the rotating torsion spring. When it is necessary to use the cleaning scraper to clean the inner wall of the dust collector, the moving component drives the rotating lever to move. The moving component drives the rotating lever to move down, and the rotating lever moves down to contact the cleaning scraper and drive the cleaning scraper to rotate until the cleaning scraper is pressed against the inner wall of the dust collector, and the subsequent cleaning work can be carried out. After the cleaning is completed, the moving component controls the rotating lever to move up, and the cleaning scraper rotates back to its original position and detaches from the inner wall of the dust collector under the action of the rotating torsion spring. Then the cleaning block can be moved back to its original position.

[0018] Optionally, the moving component includes:

[0019] A movable iron block is vertically slidably mounted on a cleaning block, and a rotating lever is mounted on the movable iron block;

[0020] An electromagnet block is disposed on a cleaning block and located below a movable iron block. When the electromagnet block is energized, it attracts the movable iron block.

[0021] By adopting the above technical solution, an electromagnet block is installed on the cleaning block. When it is necessary to drive the rotating lever to rotate the cleaning scraper, the electromagnet block is energized. The energized electromagnet block attracts the moving iron block. After being attracted by the electromagnet block, the moving iron block moves downward, which drives the rotating lever to move downward, thus completing the driving work of driving the rotating lever to move downward. After the electromagnet block is de-energized, the rotating lever and the moving iron block move upward back to their original positions as the cleaning scraper rotates.

[0022] Optionally, the drive mechanism includes:

[0023] A drive screw is rotatably mounted on the dust collector and threadedly connected to the cleaning block.

[0024] A drive motor is mounted on the dust collector and its output shaft is connected to a drive screw.

[0025] By adopting the above technical solution, the drive motor starts and drives the drive screw to rotate, the drive screw rotates and drives the cleaning block to move, the cleaning block moves and drives the cleaning scraper to move, and the cleaning scraper scrapes off the dust adhering to the inner wall of the dust collector, thus completing the driving work of moving the cleaning block.

[0026] Optionally, the dust collector is provided with a vibration mechanism for vibrating the entire dust collector, the vibration mechanism comprising:

[0027] A vibratory motor is mounted on the dust collection box;

[0028] An eccentric wheel is mounted on the output shaft of the vibration motor.

[0029] By adopting the above technical solution, the vibration motor starts and drives the eccentric wheel to rotate. The rotation of the eccentric wheel causes the vibration motor to vibrate due to the continuous change of the center of gravity. The vibration of the vibration motor causes the dust collection box to vibrate, thereby causing the inner wall of the dust collection box to vibrate, reducing the probability of dust particles adhering to the inner wall of the dust collection box.

[0030] Optionally, the frame is equipped with shock absorbers and shock-absorbing springs, and the frame is connected to the dust collection box through the shock absorbers and shock-absorbing springs.

[0031] By adopting the above technical solution, shock absorbers and shock-absorbing springs are installed on the frame, thereby reducing the probability of damage and detachment of the connection between the dust collector box and the frame during vibration. This not only ensures the vibration effect of the dust collector box but also improves the overall service life of the dust collector.

[0032] Optionally, the cleaning block is provided with a rinsing nozzle, one end of which is connected to a water source, and the other end of which is positioned facing the opening of the cleaning scraper.

[0033] By adopting the above technical solution, a rinsing nozzle is installed on the cleaning block. The rinsing nozzle can spray water to clean the cleaning scraper, thereby reducing the probability of dust sticking to the cleaning scraper when it scrapes the dust block, making the surface of the cleaning scraper clean and tidy, and ensuring the cleaning effect of the cleaning scraper on the inner wall of the dust collection box.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. By using a rotating mechanism to rotate the cleaning scraper on the cleaning block, the cleaning scraper comes into contact with the inner wall of the dust collector. Then, the drive mechanism drives the cleaning block to move along the inner wall of the dust collector. The movement of the cleaning block drives the cleaning scraper to move. The cleaning scraper scrapes off the dust clumps adhering to the inner wall of the dust collector, thus completing the cleaning work of the inner wall of the dust collector and reducing the probability that the dust clumps accumulated on the inner wall of the dust collector will adversely affect the subsequent dust discharge work of the dust collector.

[0036] 2. By using the moving component to drive the rotating lever to move, the moving component drives the rotating lever to move down, and the rotating lever moves down to contact the cleaning scraper and drive the cleaning scraper to rotate until the cleaning scraper is pressed against the inner wall of the dust collection box, and then the subsequent cleaning work can be carried out.

[0037] 3. By installing shock absorbers and shock-absorbing springs on the frame, the probability of damage and detachment of the connection between the dust collector box and the frame during vibration is reduced, which not only ensures the vibration effect of the dust collector box but also improves the overall service life of the dust collector.

[0042] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0043] This application discloses a dust collector for concrete production.

[0044] Reference Figure 1 and Figure 2 The dust collector for concrete production includes a frame 1 and a dust collection box 11 mounted on the frame 1. The frame 1 is equipped with a cleaning device 2 for cleaning the inner wall of the dust collection box 11.

[0045] Reference Figure 2 and Figure 3 The cleaning device 2 includes a cleaning block 21, a cleaning scraper 22, a rotating mechanism 23, and a driving mechanism 24. The cleaning block 21 is slidably mounted inside the dust collector 11 along its inner wall. The cleaning scraper 22 is rotatably mounted on the outer wall of the cleaning block 21. The rotating mechanism 23 is mounted on the cleaning block 21 and drives the cleaning scraper 22 to rotate, causing the scraper 22 to abut against the inner wall of the dust collector 11. The driving mechanism 24 is mounted on the dust collector 11 and drives the cleaning block 21 to move along its inner wall.

[0046] Reference Figure 2 and Figure 3 The cleaning scraper 22 on the cleaning block 21 is rotated using the rotating mechanism 23, causing the scraper 22 to come into contact with the inner wall of the dust collection box 11. Then, the driving mechanism 24 drives the cleaning block 21 to move along the inner wall of the dust collection box 11. The movement of the cleaning block 21 drives the scraper 22 to move, and the scraper 22 scrapes off the dust clumps adhering to the inner wall of the dust collection box 11, thus completing the cleaning of the inner wall of the dust collection box 11. This reduces the probability that the dust clumps accumulated on the inner wall of the dust collection box 11 will adversely affect the subsequent dust discharge operation of the dust collection box 11.

[0047] Reference Figure 2 and Figure 3The rotating mechanism 23 includes a torsion spring 31, a rotating lever 32, and a moving assembly 33. One end of the torsion spring 31 is fixedly mounted on the outer wall of the cleaning block 21, and the other end is fixedly connected to the outer wall of the cleaning scraper 22. Under the action of the torsion spring 31, the cleaning scraper 22 rotates to a fixed position and disengages from the inner wall of the dust collection box 11. The rotating lever 32 is vertically slidably mounted on the outer wall of the cleaning block 21. The moving assembly 33 is disposed on the cleaning block 21 and is used to drive the rotating lever 32 to move. Under the action of the moving assembly 33, the rotating lever 32 abuts against the cleaning scraper 22 and drives the cleaning scraper 22 to abut against the inner wall of the dust collection box 11.

[0048] Reference Figure 2 and Figure 3 The moving component 33 includes a moving iron block 34 and an electromagnet block 35. The moving iron block 34 is vertically slidably mounted on the cleaning block 21, and a rotating lever 32 is fixedly mounted on the lower surface of the moving iron block 34. The electromagnet block 35 is fixedly mounted on the upper surface of the cleaning block 21 and located below the moving iron block 34. When the electromagnet block 35 is energized, it attracts the moving iron block 34.

[0049] Reference Figure 3 When it is necessary to drive the rotating lever 32 to rotate the cleaning scraper 22, the electromagnet 35 is energized. The energized electromagnet 35 attracts the moving iron block 34. After being attracted by the electromagnet 35, the moving iron block 34 moves downward, which in turn drives the rotating lever 32 downward, thus completing the driving work of driving the rotating lever 32 downward. After the electromagnet 35 is de-energized, the rotating lever 32 and the moving iron block 34 move back to their original positions as the cleaning scraper 22 rotates.

[0050] Reference Figure 2 and Figure 3 The drive mechanism 24 includes a drive screw 36 and a drive motor 37. The drive screw 36 is rotatably mounted on the inner wall of the dust collector 11 and threadedly connected to the cleaning block 21. The drive motor 37 is fixedly mounted on the outer wall of the dust collector 11, and its output shaft is connected to the drive screw 36. When the drive motor 37 starts, it drives the drive screw 36 to rotate. The rotation of the drive screw 36 drives the cleaning block 21 to move. The movement of the cleaning block 21 drives the cleaning scraper 22 to move. The movement of the cleaning scraper 22 scrapes off the dust adhering to the inner wall of the dust collector 11, thus completing the driving work for moving the cleaning block 21.

[0051] Reference Figure 3A rinsing nozzle 38 is fixedly installed on the upper surface of the cleaning block 21. One end of the rinsing nozzle 38 is connected to a water source, and the other end of the rinsing nozzle 38 is set towards the opening of the cleaning scraper 22. After water is passed through the rinsing nozzle 38, the cleaning scraper 22 is sprayed with water for cleaning, thereby reducing the probability that dust blocks will adhere to the cleaning scraper 22 when it scrapes dust blocks, making the surface of the cleaning scraper 22 clean and tidy, and ensuring the cleaning effect of the cleaning scraper 22 on the inner wall of the dust collection box 11.

[0052] Reference Figure 1 and Figure 2 The dust collector 11 is equipped with a vibration mechanism 4 for vibrating the entire dust collector 11. The vibration mechanism 4 includes a vibration motor 41 and an eccentric wheel 42. The vibration motor 41 is fixedly mounted on the outer wall of the dust collector 11. The eccentric wheel 42 is fixedly mounted on the output shaft of the vibration motor 41. A shock absorber 43 and a shock-absorbing spring 44 are fixedly mounted on the frame 1, and the frame 1 is connected to the dust collector 11 through the shock absorber 43 and the shock-absorbing spring 44.

[0053] Reference Figure 2 When the vibration motor 41 starts, it drives the eccentric wheel 42 to rotate. As the center of gravity of the eccentric wheel 42 rotates, it drives the vibration motor 41 to vibrate. The vibration of the vibration motor 41 drives the dust collection box 11 to vibrate, thereby causing the inner wall of the dust collection box 11 to vibrate, which reduces the probability of dust particles adhering to the inner wall of the dust collection box 11.

[0054] The working principle of this application embodiment is as follows:

[0055] Under normal circumstances, the cleaning scraper 22 is fixed to the cleaning block 21 and detached from the inner wall of the dust collector 11 under the action of the rotating torsion spring 31. When it is necessary to use the cleaning scraper 22 to clean the inner wall of the dust collector 11, the electromagnet block 35 is energized to drive the rotating lever 32 to move. The rotating lever 32 moves down to contact the cleaning scraper 22 and drives the cleaning scraper 22 to rotate until the cleaning scraper 22 is pressed against the inner wall of the dust collector 11. Then, the drive motor 37 starts to drive the drive screw 36 to rotate. The rotation of the drive screw 36 drives the cleaning block 21 and the cleaning scraper 22 to move. The moving cleaning scraper 22 scrapes the dust off the inner wall of the dust collector 11, thereby completing the cleaning work of the inner wall of the dust collector 11 and reducing the probability that the dust accumulated on the inner wall of the dust collector 11 will adversely affect the subsequent dust discharge work of the dust collector 11.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
