Description

Technical Field

[0001] This invention relates to the field of dust suppression devices, specifically a dust suppression device for concrete and cement processing. Background Technology

[0002] During the concrete and cement processing, processes such as raw material crushing, mixing, and transportation generate a large amount of dust. This dust not only pollutes the surrounding environment but also harms the health of operators. Furthermore, dust accumulation can affect the normal operation of equipment. Therefore, dust suppression devices are needed to control and treat the dust.

[0003] Existing dust suppression devices for concrete and cement processing mostly use atomizing nozzles with fixed spacing for spray dust suppression. However, these devices have the following shortcomings: First, the nozzle spacing cannot be adjusted according to the dust diffusion range of the processing scene, resulting in limited dust suppression coverage and poor adaptability to large processing areas or scenes with high local dust concentrations. Second, the overall height of the device is fixed, and the spray height cannot be adjusted according to the height of the processing equipment or the height of the raw material stack, resulting in poor dust suppression effect. Third, the device has insufficient support stability and is prone to tilting when the ground of the processing site is uneven, affecting the safety of dust suppression operations.

[0004] Therefore, those skilled in the art have provided a dust suppression device for concrete and cement processing to solve the problems mentioned in the background art. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] As mentioned in the background section of this application, research has found that existing dust suppression devices for concrete and cement processing mostly use atomizing nozzles 33 with fixed spacing for spray dust suppression. However, these devices have the following shortcomings: First, the nozzle spacing cannot be adjusted according to the dust diffusion range of the processing scene, resulting in limited dust suppression coverage and poor adaptability to large-area processing areas or scenes with high local dust concentrations. Second, the overall height of the device is fixed, and the spray height cannot be adjusted according to the height of the processing equipment, the height of the raw material stack, etc., resulting in poor dust suppression effect. Third, the device has insufficient support stability and is prone to tilting when the ground of the processing site is uneven, affecting the safety of dust suppression operations.

[0023] To address the aforementioned shortcomings, this application discloses a dust suppression device for concrete and cement processing, which solves the problems of existing dust suppression devices such as non-adjustable nozzle spacing, fixed height, and poor stability, achieving the effects of flexible adaptation to different processing scenarios, comprehensive dust suppression coverage, and stable and safe use.

[0024] The following will describe in detail, with reference to the accompanying drawings, how the solution of this application solves the above-mentioned technical problems.

[0025] Please see Figures 1-7 In this embodiment of the invention, a dust suppression device for concrete cement processing includes a base 1. The outer side of the base 1 is provided with a telescopic adjustable support leg assembly, and a vertical pole 16 is provided above the base 1. A support seat 19 is fixedly connected to the top of the vertical pole 16, and strip plates 20 are fixedly connected to both sides of the support seat 19. Several atomizing nozzles 33 are provided below each strip plate 20. A spacing adjustment assembly is provided between the atomizing nozzle 33 on the same side and the corresponding strip plate 20. A lifting drive assembly is provided between the base 1 and the vertical pole 16. The base 1 provides a basic installation support surface for the entire device. The telescopic adjustable support leg assembly ensures that the device is placed stably under different ground conditions. The upright 16 serves as a vertical support structure connecting the base 1 and the support seat 19. The support seat 19 and the strip plates 20 on both sides together form the mounting carrier for the atomizing nozzles 33. The spacing adjustment assembly can flexibly change the distribution spacing of the atomizing nozzles 33 on the same side. The lifting drive assembly can precisely adjust the vertical height of the atomizing nozzles 33. All core components work together to form a complete functional link of "stable support - height adjustment - spacing control - atomization dust suppression", providing a structural foundation for adapting to different processing scenarios, expanding the dust suppression coverage, and improving the dust suppression effect.

[0026] In this embodiment, the spacing adjustment component specifically includes: a folding frame 30 disposed below the strip plate 20; a connecting seat 32 fixedly connected between the folding frame 30 and the atomizing nozzle 33; a water outlet pipe 36 provided between each connecting seat 32 on the same side; each connecting seat 32 and the water outlet pipe 36 connected by a short pipe 37; and the connecting seat 32 connected to the corresponding atomizing nozzle 33; a movable block 27 fixedly connected to the top of one end of the folding frame 30; and a rectangular plate 29 fixedly connected to the top of the other end of the folding frame 30; a strip groove 23 opened on the top surface of the strip plate 20; and a movable seat 24 movably connected to the top of the strip groove 23; the movable seat 24 and the movable block 27 are connected to each other. The movable block 27 is movably connected inside the strip groove 23 and matches it. A motor support plate 21 is fixedly connected to one side of the movable seat 24, and a lead screw support plate 22 is fixedly connected to the other side of the movable seat 24. A transmission lead screw 25 is movably connected between the motor support plate 21 and the lead screw support plate 22, and the transmission lead screw 25 passes through the movable seat 24 and is threaded to it. A drive motor 26 is fixedly connected to one side of the motor support plate 21, and the output shaft of the drive motor 26 is fixedly connected to the transmission lead screw 25. Two parallel optical axes 28 are fixedly connected to one side of the rectangular plate 29, and one end of the optical axis 28 is fixedly connected to the strip plate 20. This setup clarifies the specific implementation structure and function of the spacing adjustment component. The drive motor 26 provides the power source for spacing adjustment, driving the transmission screw 25 to rotate between the motor support plate 21 and the screw support plate 22. Through the threaded engagement between the transmission screw 25 and the moving seat 24, the moving seat 24 and the connected moving block 27 are pushed to move smoothly laterally along the strip groove 23. Two parallel optical shafts 28 fixed on one side of the rectangular plate 29, one end of which is fixedly connected to the strip plate 20, provide rigid guidance for the movement of the moving block 27, preventing offset or shaking during adjustment. The movement of the moving block 27 drives the folding frame 30 to extend and retract, thereby driving the bottom connecting seat 32 and the atomizing nozzle 33 to move synchronously, realizing precise adjustment of the spacing between multiple atomizing nozzles 33 on the same side to adapt to different dust diffusion ranges. The interconnected design of the connecting seat 32, the water outlet pipe 36, and the short pipe 37 provides a continuous and stable water supply to all atomizing nozzles 33. The rectangular plate 29 forms a support limit on the other end of the folding frame 30, ensuring the overall stability of the adjustment structure.

[0027] In this embodiment, a T-joint 34 is fixedly connected to one side of the bottom surface of the support base 19, and the bottom connector of the T-joint 34 is connected to a water inlet pipe 35. The other two connectors of the T-joint 34 are respectively connected to two water outlet pipes 36. This arrangement optimizes the water transmission system of the device. The T-joint 34 at the bottom of the support base 19 serves as a core diversion component, which evenly distributes the external water source introduced by the water inlet pipe 35 to the water outlet pipes 36 on both sides, realizing the synchronous water supply from a single water inlet to the dual-sided atomizing nozzle 33 group. This eliminates the need for additional multi-way water inlet pipes and simplifies the water circuit layout. At the same time, the diversion design of the T-joint 34 ensures that the water supply pressure of the water outlet pipes 36 on both sides is consistent, avoiding the difference in spray effect of the atomizing nozzles 33 on both sides due to uneven water supply, and improving the uniformity and reliability of the overall dust suppression.

[0028] In this embodiment, the lifting drive assembly specifically includes: a stepper motor 13 fixed at the center of the top surface of the base 1, a lifting screw 14 fixedly connected to the top output shaft of the stepper motor 13, and the lifting screw 14 passing through the upright 16 and threadedly connected thereto, a bearing seat 15 fixedly connected to the bottom of the outer side of the upright 16, and a limiting member provided between the bearing seat 15 and the base 1, and a cleaning member provided below the bearing seat 15. This setup defines the core structure and function of the lifting drive assembly. The stepper motor 13, fixed to the top of the base 1, provides power for height adjustment. Its output shaft drives the lifting screw 14 to rotate. By utilizing the threaded engagement between the lifting screw 14 and the upright 16, the rotational motion is converted into the vertical linear motion of the upright 16, achieving precise control of the longitudinal height of the atomizing nozzle 33 to adapt to processing equipment, raw material stacks, or dust diffusion longitudinal ranges of different heights. The bearing seat 15 at the bottom of the upright 16 provides the installation base for the limiting component and the cleaning component. The limiting component ensures the stability of the lifting process of the upright 16, while the cleaning component simultaneously cleans the dust at the bottom of the equipment, organically combining the height adjustment function with the auxiliary maintenance function, thus improving the overall practicality of the device.

[0029] In this embodiment, the limiting component specifically includes two limiting shafts 17 fixed side-by-side to the top surface of the base 1. The top ends of the limiting shafts 17 pass through the support seat 15 and are fixedly connected to a first anti-detachment head 18. The top ends of the limiting shafts 17 pass through the support seat 15, providing rigid guidance for the lifting and lowering movement of the upright 16, limiting the rotational deviation of the upright 16 with the lifting screw 14 during the lifting and lowering process, ensuring that the height adjustment of the atomizing nozzle 33 is always carried out in the vertical direction, and avoiding the spray range from deviating from the target dust suppression area due to deviation; the first anti-detachment head 18 at the top end of the limiting shafts 17 effectively prevents the support seat 15 from detaching from the limiting shafts 17 during the lifting and lowering process, eliminating potential safety hazards in equipment operation, and ensuring the stability and safety of the height adjustment process.

[0030] In this embodiment, the cleaning component specifically includes: an annular plate 38 sleeved around the lifting screw 14; shafts 39 are fixedly connected to both sides of the top surface of the annular plate 38, and the top of the shafts 39 passes through the bearing seat 15 and is fixedly connected to a second anti-detachment head 40; brush bristles 31 are fixedly connected to the inner wall of the annular plate 38. The annular plate 38 is linked to the bearing seat 15 through the shafts 39 and can move up and down synchronously with the lifting of the upright 16. The brush bristles 31 fixed to the inner wall of the annular plate 38 can directly wipe and clean the dust on the surface of the lifting screw 14 and the top surface of the base 1, preventing dust from accumulating in the thread gap of the lifting screw 14 or on the surface of the base 1, and preventing dust from affecting the transmission accuracy and service life of the lifting screw 14; the second anti-detachment head 40 at the top of the shaft 39 limits the maximum descent stroke of the annular plate 38, preventing it from detaching, ensuring the continuous and stable operation of the cleaning function, and reducing the maintenance frequency and difficulty of the equipment.

[0031] In this embodiment, the telescopic adjustable support assembly specifically includes: four rectangular sleeves 2 evenly fixed on the outer side of the base 1, a telescopic inner rod 3 movably connected inside the rectangular sleeve 2, and a fastening pin 4 threadedly connected to one side of the top surface of the rectangular sleeve 2, a square seat 5 fixedly connected to one end of the telescopic inner rod 3, and a threaded rod 6 threadedly connected inside the square seat 5, a handle 7 fixedly connected to the top end of the threaded rod 6, and a support foot 8 fixedly connected to the bottom end of the threaded rod 6. The telescopic adjustable support leg assembly allows for flexible adjustment of the lateral extension length of the support leg 8 through the sliding engagement of the rectangular sleeve 2 and the telescopic inner rod 3, adapting to different sizes of processing site layouts and expanding the support coverage of the device. By rotating the handle 7 to drive the threaded rod 6 to rotate within the square base 5, the vertical height of the support leg 8 can be independently adjusted, quickly compensating for support differences caused by uneven ground and ensuring that the base 1 remains level. The fastening pin 4 on the rectangular sleeve 2 can lock the extension position of the telescopic inner rod 3, ensuring that the structure is fixed after the support leg 8 is adjusted. The entire device provides stable support in complex ground environments, improving equipment safety during dust suppression operations.

[0032] In this embodiment, a circular groove 9 is provided at the center of the bottom surface of the base 1, and a circular strong magnet 10 is fixedly connected to the center of the top surface of the circular groove 9. Four slots 11 communicating with the rectangular sleeve 2 are provided on the inner side of the circular groove 9, and an arc-shaped groove 12 matching the circular strong magnet 10 is provided at the other end of the telescopic inner rod 3. When the device is stored or moved, after the telescopic inner rod 3 is retracted into the rectangular sleeve 2, the arc-shaped groove 12 can be attracted and fixed with the circular strong magnet 10, preventing the telescopic inner rod 3 from loosening and shifting in the stored state, thus enhancing the compactness of the device structure. The four slots 11 on the inner side of the circular groove 9 communicate with the rectangular sleeve 2, providing clearance space for the attraction and positioning of the telescopic inner rod 3, ensuring that the telescopic inner rod 3 can be fully retracted and tightly fitted with the circular strong magnet 10, facilitating the handling and storage of the device and improving ease of use.

[0033] The working principle of this dust suppression device for concrete and cement processing revolves around the entire process of "installation and fixing - height adjustment - spacing adjustment - dust suppression operation - cleaning and maintenance - storage and relocation". The various components achieve efficient dust suppression through the coordinated operation of mechanical transmission and water transmission, as detailed below: Installation and Fixing Stage: Before using the device, the support adjustment needs to be completed according to the size of the processing site and the flatness of the ground: First, loosen the fastening pin 4 at the top of the rectangular sleeve 2, pull the telescopic inner rod 3 to slide along the rectangular sleeve 2, adjust to a suitable lateral extension length, and then tighten the fastening pin 4 again to lock the position of the telescopic inner rod 3 so that the four legs 8 form a stable support range; then rotate the handle 7 above each leg 8 to drive the threaded rod 6 to rotate in the square base 5. The vertical movement of the threaded rod 6 drives the legs 8 to rise and fall. The independent adjustment of the four legs 8 compensates for the difference in ground height, and finally keeps the base 1 in a horizontal state, providing a foundation for the stable operation of the subsequent functional components.

[0034] Height adjustment stage: Based on the height of the processing equipment, the height of the raw material stack, or the longitudinal range of dust diffusion, start the stepper motor 13 at the center of the top surface of the base 1: The output shaft of the stepper motor 13 drives the lifting screw 14 to rotate. Since the lifting screw 14 is threadedly connected to the upright 16, and the upright 16 slides with the two limit shafts 17 through the bearing seat 15 at the bottom, the rotational motion of the lifting screw 14 is converted into the vertical lifting motion of the upright 16. The limit shafts 17 restrict the rotational freedom of the upright 16, ensuring that the upright 16 moves smoothly in the vertical direction, thereby driving the top support seat 19, the strip plate 20, and the atomizing nozzle 33 to rise and fall synchronously until the preset height is reached, and then turn off the stepper motor 13 to complete the precise adaptation of the spray height.

[0035] Spacing Adjustment Stage: For the lateral range of dust diffusion or local dust concentration in the processing area, the drive motor 26 on the strip plate 20 is activated. The output shaft of the drive motor 26 drives the transmission screw 25 to rotate between the motor support plate 21 and the screw support plate 22. The threaded engagement between the transmission screw 25 and the movable seat 24 generates a lateral thrust, pushing the movable seat 24 to move laterally along the strip groove 23. The movable seat 24 is fixedly connected to the movable block 27 at one end of the folding frame 30, and one end of each of the two parallel optical shafts 28 on one side of the rectangular plate 29 is fixedly connected to the strip plate 20, providing stable guidance for the movement of the movable block 27 and preventing deviation. The lateral movement of the movable block 27 drives the folding frame 30 to extend and retract. The other end of the folding frame 30 is attached to the bottom of the strip plate 20 via the movable block 27, ensuring stability during the extension and retraction process. When the folding frame 30 extends and retracts, it drives the connecting seat 32 at the bottom and the atomizing nozzle 33 to move synchronously, achieving uniform adjustment of the spacing between multiple atomizing nozzles 33 on the same side until the distribution density suitable for the dust range is reached, at which point the drive motor 26 is turned off.

[0036] Dust suppression operation stage: Connect the water inlet pipe 35 to an external high-pressure water source. The water flow enters the T-joint 34 on the bottom surface of the support base 19 through the water inlet pipe 35. After being diverted by the T-joint 34, the water flows into the water outlet pipes 36 below the strip plates 20 on both sides. The water outlet pipes 36 distribute the water flow evenly to each connecting base 32 through the short pipes 37. Finally, the water is atomized into fine water droplets by the atomizing nozzles 33 below the connecting base 32 and sprayed out to form a large area of ​​fog curtain. The fog curtain comes into full contact with the dust particles generated during the concrete cement processing, causing the dust particles to absorb moisture, increase their weight, and settle, thereby suppressing dust diffusion and purifying the working environment. Since the spray height and nozzle spacing have been adapted according to the actual scenario, the fog curtain can fully cover the dust generation area, ensuring dust suppression efficiency and effect.

[0037] Cleaning and maintenance phase: During the lifting and lowering of the upright 16, the bearing seat 15 moves up and down synchronously, driving the annular plate 38 to move synchronously along the axial direction of the lifting screw 14 via the shaft 39. The bristles 31 on the inner wall of the annular plate 38 are in close contact with the surface of the lifting screw 14 and the top surface of the base 1. During the movement, the dust in the thread gap of the lifting screw 14 and the residual dust on the surface of the base 1 are wiped and cleaned to prevent dust accumulation from affecting the transmission accuracy of the lifting screw 14 and to reduce dust adhesion on the surface of the equipment. The second anti-detachment head 40 at the top of the shaft 39 limits the maximum descent stroke of the annular plate 38 to prevent it from detaching, ensuring the continuous and stable operation of the cleaning function and reducing the frequency of equipment maintenance.

[0038] Storage and relocation phase: When the device is not in use, loosen the fastening pin 4 on the rectangular sleeve 2 and retract the telescopic inner rod 3 into the rectangular sleeve 2. The arc-shaped groove 12 at the other end of the telescopic inner rod 3 gradually approaches the circular strong magnet 10 in the circular groove 9 on the bottom surface of the base 1, and finally fixes the telescopic inner rod 3 through magnetic attraction. The groove 11 on the inner side of the circular groove 9 provides clearance for the attraction and positioning of the telescopic inner rod 3, ensuring that the telescopic inner rod 3 can be fully retracted and tightly fitted with the circular strong magnet 10, reducing the overall space occupied by the device, facilitating transportation and storage, and preventing the telescopic inner rod 3 from loosening and shifting during movement.
