Description

Technical Field

[0001] This invention relates to the field of dust treatment technology, and more specifically to an environmentally friendly dust treatment device. Background Technology

[0002] In the process of spray painting, dust control involves a series of measures to control, collect, and treat the generated dust, aiming to reduce or avoid its negative impact on the environment and human health. Air dust filters, as a crucial component of dust control, primarily employ filter media such as filter cloth, filter paper, or filter mesh to effectively intercept and adsorb dust particles in the air. When dust-laden gas passes through the filter, the dust is trapped, while clean air is released into the environment. Therefore, this type of equipment is indispensable in paint production and spray painting operations, effectively reducing dust emissions and preventing environmental pollution.

[0003] Traditional air dust filters work by using internal filter cartridges to separate dust from the air. However, over time, more and more dust accumulates on the filter cartridges, requiring regular disassembly and cleaning to maintain normal operation. Furthermore, in high-humidity environments such as spray painting or processes involving large amounts of water, the filter may absorb additional moisture. This not only accelerates filter cartridge clogging but also complicates cleaning due to dust condensation caused by moisture. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an environmentally friendly dust treatment device that can effectively clean dust adhering to filter cartridges.

[0005] The technical implementation of this invention is: an environmentally friendly dust treatment device, comprising:

[0010] An auxiliary mechanism is installed on the outer wall of the processing frame. The auxiliary mechanism includes a heating frame installed on the outer wall of the processing frame. An air inlet cylinder connected to the air inlet pipe is installed inside the heating frame. Heating plates for drying humid air are arranged around the air inlet cylinder.

[0011] Optionally, the backflushing mechanism includes a collection frame that is slidably disposed on the lower side of the processing frame for collecting blown-off dust. An electric push rod with its telescopic end facing upward is provided on the top of the processing frame. A sliding frame is connected to the telescopic end of the electric push rod. The sliding frame slides through the processing frame, and baffles that contact and cooperate with one side of the connecting frame are provided on both sides of the bottom of the sliding frame to control the communication state between the connecting frame and the collection frame. A front plate for blocking the air inlet pipe is provided on the bottom front side of the sliding frame. An air pump is provided on the top of the sliding frame. An air supply pipe is connected to the air outlet of the air pump. The air supply pipe slides through the sliding frame and extends into the interior of the mounting cylinder.

[0012] Optionally, the drive assembly includes a motor, a motor fixedly mounted on the top of the processing frame and located inside the assembly frame, and a rotating symmetrically arranged coupling shaft. The bottom end of the coupling shaft extends and rotates through the frame. The top end of one coupling shaft is connected to the output end of the motor, and the ends of the two coupling shafts are connected by a pulley set. Each coupling shaft is provided with a set of gears adapted to the toothed ring layout, and the gears mesh with the corresponding toothed rings.

[0013] Optionally, it also includes a positioning plate, with the positioning plate slidably inserted through the connecting plate, and the positioning plate is inserted and engaged with the corresponding hinge seat.

[0014] Optionally, the auxiliary mechanism also includes electric lead screws symmetrically installed inside the lower side of the heating frame. A scraper is threaded between the lead screw bodies of the two electric lead screws. The scraper slides against the inner wall of the air inlet cylinder. A set of guide sleeves is spaced apart on the left and right sides inside the heating frame. A collection frame is slidably inserted between the two guide sleeves. The collection frame abuts against the bottom end of the scraper. When the scraper is in the top position, the collection frame is in contact with the bottom end of the air inlet cylinder.

[0019] The beneficial effects of this invention are as follows: 1. By combining the back-blowing mechanism and the knocking mechanism, this invention can clean the filter cartridge without manual intervention. First, the powerful airflow generated by the air pump impacts the filter cartridge, causing the attached dust to fall off. The knocking rod in the knocking mechanism can further remove stubborn dust attached to the filter cartridge, ensuring a reduction in dust accumulation on the filter cartridge. In addition, the heating frame and heating plate in the auxiliary mechanism can dry the incoming dusty air, reducing the impact of moisture on the filter cartridge and preventing dust agglomeration caused by excessive humidity, thus ensuring the cleaning efficiency of the filter cartridge and achieving effective filter cartridge cleaning.

Detailed Implementation

[0036] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] Example: An environmentally friendly dust treatment device, such as Figures 1-10 As shown, it includes:

[0038] The processing frame 1 is a hollow frame. An air inlet pipe 11 is connected to the front of the processing frame 1 to guide the intake of dust-laden air. An opening and closing door 12 is hinged to the left rear of the processing frame 1 to facilitate the maintenance and cleaning of subsequent devices.

[0039] Assembly frame 2 is located on top of processing frame 1. A dust pump 3 is installed on assembly frame 2. An installation cylinder 31 is slidably inserted through the top of processing frame 1. The top of the installation cylinder 31 is connected to the air intake of the dust pump 3. A connecting frame 32 is also provided on the lower inner wall of processing frame 1. The connecting frame 32 is composed of a hollow ring and a plate structure with open left and right sides. A filter cartridge 33 for dust treatment is snapped between the connecting frame 32 and the installation cylinder 31. The distance between the installation cylinder 31 and the filter cartridge 33 can be adjusted by sliding the installation cylinder 31, and the filter cartridge 33 can be rotated to achieve easy installation and removal of the filter cartridge 33. Combined with the above components, the dust pump 3 draws in dusty air from the external spraying operation environment to ensure that the dusty air can be effectively filtered by the filter cartridge 33, thus achieving effective dust treatment.

[0040] The back-blowing mechanism 4 is set inside the processing frame 1 and uses reverse air blowing to clean the dust adhering to the filter cartridge 33.

[0041] A striking mechanism 5, installed within the processing frame 1, is used to handle stubborn, adhered dust. The striking mechanism 5 includes a frame 51 mounted on the inner wall of the processing frame 1, with an opening facing the opening / closing door 12. An auxiliary track 121 is provided on the opening / closing door 12 to mate with the opening of the frame 51, so that when the opening / closing door 12 is closed, the auxiliary track 121 connects and fits snugly with the frame 51, forming a complete frame for the stable operation of subsequent components. A set of toothed rings 55 are slidably mounted vertically on the inner wall of the frame 51, sliding along the auxiliary track 121. The toothed ring 55 is circumferentially slidable along the inner wall of the frame 51 and the auxiliary track 121. The processing frame 1 is provided with a drive assembly that extends into the frame 51. The output of the drive assembly meshes with the adjacent toothed ring 55. The toothed ring 55 is also provided with a set of hinge seats 561. Each hinge seat 561 is hinged with a connecting plate 56. A torsion spring is provided between the connecting plate 56 and the corresponding hinge seat 561. A knocking rod 57 that contacts the filter cartridge 33 is provided between the ends of the two upper and lower opposite connecting plates 56 for knocking to remove stubborn dust.

[0042] Specifically, for stubborn dust that is difficult to remove from the filter cartridge 33, the toothed ring 55 rotates to drive the striking rod 57 to operate. During operation, the striking rod 57 strikes the filter cartridge 33. Due to the hinged connection between the connecting plate 56 and the hinge seat 561, the striking rod 57 is forced to rotate under force, which in turn deforms the torsion spring, keeping the striking rod 57 rotating within a certain range. This repeated striking of the filter cartridge 33 achieves a higher frequency and more effective striking treatment, thereby ensuring the effective removal of the attached dust.

[0043] The auxiliary mechanism 6 is located on the outer wall of the processing frame 1. The auxiliary mechanism 6 includes a heating frame 61 located on the outer wall of the processing frame 1. An air inlet cylinder 62 connected to the air inlet pipe 11 is connected inside the heating frame 61. A heating element 63 for drying the humid air is arranged around the air inlet cylinder 62.

[0044] Furthermore, the heating element 63 dries the incoming dusty air, keeping the incoming gas in a hot flow state to avoid excess moisture residue. The incoming gas can reach a drier state, effectively preventing dust clumps from becoming difficult to clean. Due to the influx of heat, the interior of the processing frame 1 is kept dry and warm, further reducing the occurrence of dust clumps due to increased moisture content.

[0045] like Figure 2 , Figures 4-6As shown, the backflushing mechanism 4 includes a collection frame 41 slidably disposed on the lower side of the processing frame 1 for collecting blown-off dust. An electric push rod 42 with its telescopic end facing upwards is disposed on the top of the processing frame 1. The electric push rod 42 is located inside the assembly frame 2. A sliding frame 43 is connected to the telescopic end of the electric push rod 42. The lower end of the sliding frame 43 is a vertical plate extending downwards, causing the sliding frame 43 to slide through the processing frame 1. The sliding frame 43 can slide vertically along the assembly frame 2 and inside the processing frame 1. Baffles 431 are provided at the bottom ends of the vertical plates on both sides of the sliding frame 43, contacting and cooperating with one side of the connecting frame 32. The baffles 431 are corner plates. When the baffles 431 are in contact with the upper sides of the connecting frame 32, a closed state is formed, and the processing frame 1 and the collection frame 41 are not connected, with the dust placed inside the processing frame 1. Conversely, when the baffles 431 are disengaged from the connecting frame 32, the connection is closed. When the two ends are in contact, the connecting frame 32 communicates with the processing frame 1, and then maintains the communication with the collection frame 41, so that the dust can fall into the collection frame 41 to complete the dust collection and treatment after the split blowing. Thus, the effect of effectively controlling the communication state between the connecting frame 32 and the collection frame 41 is achieved. The bottom front side of the sliding frame 43 is provided with a front plate 432 for blocking the air inlet pipe 11. The top of the sliding frame 43 is provided with an air pump 44. The air outlet of the air pump 44 is connected to an air supply pipe 441. The air supply pipe 441 slides through the sliding frame 43 and extends into the interior of the mounting cylinder 31. A column that matches the inner diameter of the upper end of the mounting cylinder 31 is provided on the air supply pipe 441, so that the two are tightly fitted together to maintain the sealing effect. When the filter cartridge 33 is back-blown, the column follows the air supply pipe 441 to ensure the airtightness of the pipe on the mounting cylinder 31, so that the overall operation can be more stable.

[0046] like Figure 7 and Figure 8 As shown, the drive assembly includes a motor 52. The motor 52 is also fixedly installed on the top of the processing frame 1 and located inside the assembly frame 2. There are also rotating symmetrically arranged connecting shafts 53. The bottom end of the connecting shaft 53 extends and rotates through the frame 51. The top end of one side of the connecting shaft 53 is connected to the output end of the motor 52. The ends of the two connecting shafts 53 are connected by a pulley set. A set of gears 54 adapted to the layout of the toothed ring 55 is provided on each connecting shaft 53. The gears 54 mesh with the corresponding toothed ring 55.

[0047] like Figure 9 As shown, it also includes a positioning plate 562. The positioning plate 562 is slidably inserted through the connecting plate 56. The positioning plate 562 is inserted and engaged with the corresponding hinge seat 561 so as to fix the position of the subsequent strike rod 57 after it is folded.

[0048] like Figure 11 and Figure 12As shown, the auxiliary mechanism 6 also includes electric lead screws 64 symmetrically installed inside the lower side of the heating frame 61. A scraper frame 65 is threaded between the lead screw bodies of the two electric lead screws 64. The scraper frame 65 slides against the inner wall of the air inlet cylinder 62. A set of guide sleeves 66 are arranged at intervals on the left and right inside the heating frame 61. A collection frame 67 is slidably inserted between the two guide sleeves 66. The collection frame 67 abuts against the bottom end of the scraper frame 65. When the scraper frame 65 is in the top position, the collection frame 67 is in contact with the bottom end of the air inlet cylinder 62. Through the lifting and lowering operation of the scraper frame 65, the dust adhering and retained inside the air inlet cylinder 62 can be effectively treated, and the scraping treatment can be effectively achieved.

[0049] like Figure 1 , Figure 2 and Figure 13 As shown, a steering mechanism 7 is provided on the top of the heating frame 61. The steering mechanism 7 includes arc-shaped guide rails 71 symmetrically arranged on the top of the heating frame 61. A conical frame 72 is slidably arranged between the two arc-shaped guide rails 71. The bottom end of the conical frame 72 is connected to the air inlet cylinder 62 through a connecting pipe. By sliding and adjusting the position of the conical frame 72, the position of the dust-laden air intake can be effectively adjusted.

[0050] like Figure 13 As shown, the steering mechanism 7 also includes guide frames 73 symmetrically arranged on the tapered frame 72. Insert rods 74 are slidably arranged through both guide frames 73. An elastic element is provided between the insert rods 74 and the corresponding guide frames 73. The arc-shaped guide rail 71 is inserted and engaged with the insert rods 74 on the same side to fix the position of the tapered frame 72.

[0051] like Figures 1-3 As shown, the bottom of the processing frame 1 is provided with a grip frame 13 for holding, and the grip of the grip frame 13 is tilted backward to fit the tilt angle of the hand.

[0052] In use, first slide the conical frame 72 until it moves to a suitable opening position. Then, slide the adjusting rod 74 and insert it into the arc-shaped guide rail 71. Then, start the dust pump 3. The strong suction of the dust pump 3 draws dusty air from the outside environment into the conical frame 72. The dusty air then enters the air intake cylinder 62 and is dried by the heating element 63, making the incoming dusty air drier. The dried dusty air then enters the air intake pipe 11 and passes through the filter cartridge 33. The dust in the filter cartridge 33 will adhere to it, preventing dust from clumping due to high humidity. The filtered air will then continue to be drawn by the dust pump 3, pass through the mounting cylinder 31, and finally be discharged by the dust pump 3. This stabilizes the dust content during the spraying process, ensures the air environment during operation, and achieves effective dust control.

[0053] After dust removal, the filter cartridge 33 is cleaned. Simultaneously, the air pump 44 and electric push rod 42 are activated. The electric push rod 42 moves the sliding frame 43 downwards, causing the baffles 431 on both sides of the sliding frame 43 to disengage from the connecting frame 32, opening up the left and right sides of the connecting frame 32. This connects the processing frame 1, the connecting frame 32, and the central frame 41. The front plate 432 then contacts and blocks the air inlet pipe 11. The air pump 44 then fills the mounting cylinder 31 with air, providing powerful airflow. The airflow impacts the filter cartridge 33, causing the attached dust to detach. At the same time, to ensure stable air pressure inside the treatment frame 1, the air pump 44 and the air delivery pipe 441 move down together as the sliding frame 43 moves down. When the column of the air delivery pipe 441 moves to a certain distance from the air inlet of the mounting cylinder 31, the operation of the sliding frame 43 is stopped, so that the gas injected into the treatment frame 1 can be discharged through this distance, ensuring the normal operation of the entire process and thus achieving the initial cleaning treatment of dust.

[0054] Next, the motor 52 is turned on simultaneously. The motor 52 drives the rotation of the two connecting shafts 53 through the pulley set, and the gear 54 rotates accordingly, so that the gear 54 meshes with the corresponding toothed ring 55, thereby driving the toothed ring 55 to slide circumferentially along the inner wall of the frame 51 and the auxiliary track 121, so that the striking rod 57 follows the operation and comes into contact with the filter cartridge 33. The striking rod 57 is used to knock on the stubborn dust to effectively clean the stubborn dust.

[0055] Then, the collection frame 41 can be pulled to process the dust collected inside. Next, the electric screw 64 is activated to drive the scraper 65 to move down along the inner wall of the air inlet 62 to scrape off the attached dust. As the scraper 65 moves down, it naturally detaches from the contact of the collection frame 67, and then the collection frame 67 moves down to serve as the bottom container of the air inlet 62 to collect the scraped dust.

[0056] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the invention without departing from the principles and spirit of the invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for illustrative purposes only and is not intended to limit the invention; rather, the scope of protection is defined by the content of the claims.
