Description
Technical Field
[0001] This utility model relates to the technical field of dust treatment equipment, specifically to a treatment device for reducing dust pollution. Background Technology
[0002] Construction processes generate a lot of dust, which needs to be removed promptly to prevent environmental pollution.
[0003] However, the existing methods for reducing and eliminating dust are all done by manually sprinkling water, which is not very effective in removing dust from construction sites. Furthermore, workers inhale a lot of dust after working for a long time, which can damage their health.
[0004] As disclosed in CN217526890U, a dust reduction treatment device for construction services utilizes a pump and a fan. When the pump and fan are started, the pump draws water from the tank and delivers it to an atomizer. The water is then atomized and sprayed onto the construction site through nozzles, significantly reducing dust. The fan extracts the dust and delivers it to a filter box for filtration. The combined action of the pump and fan greatly improves the dust reduction efficiency and dust removal effect at the construction site.
[0005] However, during use, dust will clog the filter screen after being drawn into the filter box, which will reduce the dust removal efficiency of the device.
[0006] Therefore, we urgently need to provide a treatment device to reduce dust pollution. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Based on current technology, dust entering the filter box during operation can clog the filter screen, reducing the device's dust removal efficiency. Please refer to [link to relevant documentation]. Figures 1-5 This embodiment provides a dust collection device for reducing dust pollution, which can prevent filter clogging from affecting dust collection efficiency. The dust collection device includes a trolley 1, a dust collection box 2, an exhaust duct 3, an exhaust fan 4, an exhaust duct 5, and a filter 6. The dust collection box 2 is fixedly installed on the top left side of the trolley 1, the exhaust duct 3 is installed on the left side of the dust collection box 2, the exhaust fan 4 is installed on the right side of the dust collection box 2, the exhaust duct 5 is connected to the output end of the exhaust fan 4, and the filter 6 is installed inside the dust collection box 2. Dust collection devices are provided on the top of the trolley 1 and inside the dust collection box 2, and the dust collection devices include a cleaning mechanism, an auxiliary mechanism, and a water spraying mechanism.
[0023] The cleaning mechanism is located inside the dust collection box 2, the auxiliary mechanism is located inside the dust collection box 2, and the water spraying mechanism is located on the top of the trolley 1.
[0024] The cleaning mechanism includes a motor 701, a threaded rod 702, a guide rod 703, a connecting block 704, a rotating shaft 705, and a brush roller 706. The motor 701, model XD-5D90GN, is fixedly mounted on the upper back of the dust collector 2 and has forward and reverse rotation functions, enabling the brush roller 706 to move back and forth. The threaded rod 702 is fixedly mounted on the output end of the motor 701 and extends into the dust collector 2. The guide rod 703 is fixedly mounted inside the dust collector 2 at its lower end, directly below the threaded rod 702. Two connecting blocks 704 are used, each mounted on the threaded rod 705. Outside the threaded rod 702 and guide rod 703, the cleaning mechanism is located on the left side of the filter screen 6. The upper connecting block 704 has an internal thread and is threaded to the outside of the threaded rod 702. By starting the motor 701, the threaded rod 702 is threaded to the upper connecting block 704, so that the connecting block 704 drives the rotating shaft 705 to move back and forth linearly along the guide rod 703, cleaning the dust and impurities attached to the surface of the filter screen 6. The rotating shaft 705 is rotatably connected to the adjacent side of the upper and lower connecting blocks 704, and the brush roller 706 is fixedly installed on the outside of the rotating shaft 705.
[0025] During the cleaning process of the brush roller 706 on the filter screen 6, some impurities and dust will adhere to the brush roller 706, which will affect the cleaning effect of the brush roller 706 on the filter screen 6. Therefore, this device is also equipped with a cleaning mechanism, which includes a gear 707 and a rack 708. The gear 707 is fixedly installed on the outer side of the upper end of the rotating shaft 705, and the rack 708 is fixedly installed inside the dust collection box 2 at the upper end located to the right of the gear 707. During the process of the brush roller 706 moving back and forth to clean the filter screen 6, the gear 707 and the rack 708 mesh together, causing the gear 707 to drive the rotating shaft 705 and the brush roller 706 to rotate. When the brush roller 706 rotates, the dust on the surface of the brush roller 706 will be peeled off under the action of centrifugal force, thereby improving the cleaning effect of the brush roller 706 and thus improving the cleaning quality of the filter screen 6.
[0026] During the dust removal process, water needs to be sprayed on the surrounding environment to absorb the dust and cause it to settle. The water spraying mechanism includes a water tank 901, a pump body 902, a water outlet pipe 903, an atomizing nozzle 904, and a support block 908. The water tank 901 is fixedly installed on the right side of the top of the trolley 1, the pump body 902 is installed on the top of the water tank 901, the water outlet pipe 903 is connected to the output end of the pump body 902, the atomizing nozzle 904 is installed on the left end of the water outlet pipe 903, and the support block 908 is fixedly installed on the top of the dust collection box 2, and the support block 908 supports the water outlet pipe 903.
[0027] Example 2: Based on Example 1, please refer to Figures 1-4 The auxiliary mechanism includes a cam 801, a spring 802, a striking block 803, a connecting rod 804, and comb teeth 805. The cam 801 is fixedly installed on the outer side of the lower end of the rotating shaft 705. One end of the spring 802 is fixedly installed on the inner wall of the cam 801. The spring 802 prevents the striking block 803 from making a hard impact on the filter screen 6. The striking block 803 is slidably connected to the inner wall of the cam 801 and fixedly connected to the other end of the spring 802. When the brush roller 706 rotates, it will drive the cam 801 to rotate. As the cam 801 rotates, the striking block 803 will make intermittent impacts on the filter screen 6. The filter screen 6 vibrates, thereby dislodging impurities that are difficult to clean by the brush roller 706. The connecting rod 804 is bolted to the left side of the upper and lower connecting blocks 704. The comb teeth 805 are fixedly installed on the outside of the connecting rod 804. The surface of the comb teeth 805 has evenly distributed grooves, and the width of the grooves is greater than the diameter of the brush on the brush roller 706. When the brush roller 706 rotates, the brush on it will contact the comb teeth 805 and enter the grooves, thereby scraping off the impurities adhering to the brush through the grooves, cleaning the brush roller 706 and improving the subsequent cleaning effect of the brush roller 706.
[0028] Example 3: Based on Example 1, please refer to Figures 1-5To prevent dust from being stirred up inside the dust collector 2, the water spraying mechanism of this device also includes a branch pipe 905, a valve 906, and a second atomizing nozzle 907. The branch pipe 905 is connected to the bottom left side of the water outlet pipe 903 and extends into the dust collector 2. The valve 906 is installed on the outside of the branch pipe 905, and the second atomizing nozzle 907 is installed at the bottom of the branch pipe 905. The first atomizing nozzle 904 and the second atomizing nozzle 907 are model HY-72-1A. By opening the valve 906, the second atomizing nozzle 907 sprays water mist to absorb the dust inside the dust collector 2, preventing the dust from being stirred up inside the dust collector 2 and causing further blockage of the filter screen 6.
[0029] In use, the device is moved to the desired dust removal location using the trolley 1. Then, the exhaust fan 4 is activated to create negative pressure inside the dust collection box 2. Under this negative pressure, outside air and dust are drawn into the dust collection box 2 through the exhaust pipe 3. The dust and impurities are retained inside the dust collection box 2 by the filter screen 6, and the gas is discharged through the exhaust pipe 5. Simultaneously, the pump body 902 is activated, causing water from the water tank 901 to enter the atomizing nozzle 904 through the water outlet pipe 903. The atomizing nozzle 904 sprays water mist to absorb dust from the surrounding environment. While the filter screen 6 is filtering dust, the motor 701 can be activated to drive the threaded rod 702, which is threadedly connected to the upper connecting block 704. This causes the connecting block 704 to drive the rotating shaft 705, which moves linearly back and forth along the guide rod 703, cleaning the dust and impurities adhering to the surface of the filter screen 6. During the cleaning process of the filter screen 6, the brush roller 706 engages with the gear 707 and the rack 708, causing the gear 707 to drive the rotating shaft 705 and the brush roller 706 to rotate. When the brush roller 706 rotates, the dust on the surface of the brush roller 706 will be peeled off under the action of centrifugal force, thereby improving the cleaning effect of the brush roller 706. At the same time, as the brush roller 706 rotates, the brush on it will contact the comb teeth 805 and enter the tooth groove, thereby scraping off the impurities adhering to the brush through the tooth groove, thus cleaning the brush roller 706 and improving the subsequent cleaning effect of the brush roller 706. In order to prevent the dust inside the dust collection box 2 from being stirred up, the valve 906 can be opened to allow the atomizing nozzle 907 to spray water mist to absorb the dust inside the dust collection box 2, so that it falls to the bottom of the dust collection box 2, and can be cleaned later by opening the door of the dust collection box 2.
