Description

Technical Field

[0001] The invention relates to the technical field of dust treatment, and in particular to a dust treatment device for environmental protection. Background Art

[0002] In the process of spraying, dust treatment is a series of measures to control, collect and treat the dust generated, with the aim of reducing or avoiding its negative impact on the environment and human health. Among them, air dust filters, as an important part of dust treatment, mainly use filter media such as filter cloth, filter paper or filter screen to effectively intercept and adsorb dust particles in the air. When the dust-laden gas passes through the filter, the dust is trapped and the clean air is released into the environment. It can be seen that this type of equipment is indispensable in paint production and spraying operations, and can effectively reduce dust emissions to prevent environmental pollution.

[0003] The working principle of traditional air dust filter is to use internal filter cartridge to separate dust in the air. However, as the running time increases, more and more dust will accumulate on the filter cartridge, and it must be disassembled and cleaned regularly to maintain its normal operation. What's more, due to the high humidity of the spraying environment or when the processing involves a lot of water, the filter may absorb additional moisture, which not only speeds up the clogging speed of the filter cartridge, but also makes the cleaning of the filter cartridge more complicated due to the condensation of dust caused by moisture.

DETAILED DESCRIPTION

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0032] Embodiment: A dust treatment device for environmental protection, such as Figure 1-Figure 10 As shown, including: The processing frame 1 is a hollow frame body. An air inlet pipe 11 for guiding the inhaled dusty air is connected to the front side of the processing frame 1. An opening and closing door 12 is hingedly provided on the left side of the rear of the processing frame 1 to facilitate the subsequent maintenance and cleaning of the device. The assembly frame 2 is arranged on the top of the processing frame 1. A dust suction pump 3 is arranged on the assembly frame 2. A mounting cylinder 31 is slidably penetrated on the top of the processing frame 1. The top of the mounting cylinder 31 is connected to the air suction port of the dust suction pump 3. A connecting frame 32 is also arranged on the inner wall of the lower side of the processing frame 1. The connecting frame 32 is composed of a hollow ring body and a plate frame connected on the left and right sides. A filter cartridge 33 for treating dust is clamped between the connecting frame 32 and the mounting cylinder 31. The spacing between the mounting cylinder 31 and the filter cartridge 33 is adjusted by sliding the mounting cylinder 31, and then the filter cartridge 33 is rotated to operate, so that the filter cartridge 33 can be easily disassembled and assembled. In combination with the above-mentioned components, the dust-containing air in the external spraying operation environment is sucked by the dust suction pump 3 to ensure that the dust-containing air can be effectively filtered through the filter cartridge 33, and the dust is filtered and sieved to achieve effective dust treatment; The back-blowing mechanism 4 is arranged in the processing frame 1 and adopts a reverse blowing method to clean the dust attached to the filter cartridge 33; The knocking mechanism 5 is arranged in the processing frame 1 to process the attached dust that is difficult to clean. The knocking mechanism 5 includes a surrounding frame 51 arranged on the inner wall of the processing frame 1. The notch of the surrounding frame 51 faces the opening and closing door 12. The opening and closing door 12 is provided with an auxiliary track 121 that can match the notch of the surrounding frame 51, so that when the opening and closing door 12 is closed, the auxiliary track 121 will be connected and fit with the surrounding frame 51, thereby forming a complete framework for the stable operation of subsequent parts. A group of toothed rings 55 are arranged on the inner wall of the surrounding frame 51 in an interval sliding manner, and the toothed rings 55 slide with the auxiliary track 121. The toothed ring 55 is matched with the surrounding frame 51 and the inner wall of the auxiliary track 121, so that the toothed ring 55 can slide circumferentially along the surrounding frame 51 and the inner wall of the auxiliary track 121. The processing frame 1 is provided with a driving assembly extending into the surrounding frame 51, and the output member of the driving assembly is meshed with the adjacent toothed ring 55. The toothed ring 55 is also provided with a group of hinged seats 561, and the hinged seats 561 are hingedly provided with connecting plates 56. A torsion spring is provided between the connecting plates 56 and the corresponding hinged seats 561. A knocking rod 57 in contact with the filter cartridge 33 is provided between the ends of the two upper and lower connecting plates 56, so as to knock and remove stubborn dust; Specifically, for the stubborn dust on the filter cartridge 33 that is difficult to handle, the toothed ring 55 is rotated to drive the knocking rod 57 to operate, so that the knocking rod 57 knocks on the filter cartridge 33 during operation. Because the connecting plate 56 is hingedly connected to the hinge seat 561, the knocking rod 57 is forced to rotate under force, and then the torsion spring is deformed, so that the knocking rod 57 maintains a certain range of rotation, thereby reciprocatingly knocking on the filter cartridge 33, so as to achieve a more high-frequency and effective knocking treatment, thereby ensuring the effective cleaning of attached dust.

[0033] The auxiliary mechanism 6 is arranged on the outer wall of the processing frame 1. The auxiliary mechanism 6 includes a heating frame 61 arranged on the outer wall of the processing frame 1. The heating frame 61 is connected to an air intake cylinder 62 connected to the air intake pipe 11. The air intake cylinder 62 is surrounded by a heating plate 63 for drying and treating wet air.

[0034] Furthermore, the incoming dust-laden air is dried by the heating plate 63 so that the incoming gas maintains a heat flow state to avoid excess moisture residue, and the incoming gas can reach a drier state, effectively preventing dust clots from being difficult to clean. In addition, due to the influx of heat flow, the internal environment of the processing frame 1 is kept dry and warm, further reducing the occurrence of dust clots due to increased water content.

[0035] like Figure 2 , Figure 4-Figure 6As shown, the back-blowing mechanism 4 includes a concentrated frame 41 which is slidably arranged at the lower side of the processing frame 1 and is used to collect the blown-off dust. The top of the processing frame 1 is provided with an electric push rod 42 with a telescopic end facing upward. 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 body extending downward, so that the sliding frame 43 slides through the processing frame 1. The sliding frame 43 can slide in the up and down directions along the assembly frame 2 and the inside of the processing frame 1, and the bottom ends of the vertical plates on both sides of the sliding frame 43 are provided with baffles 431 that contact and cooperate with one side of the connecting frame 32. The baffles 431 are in the shape of corner plates. When the baffles 431 are in contact with both sides of the plate frame upper end of the connecting frame 32, the two form a closed state, the processing frame 1 is not connected to the concentrated frame 41, and the dust is placed inside the processing frame 1; on the contrary, when the baffles 431 are separated from the plate frame upper end of the connecting frame 32 When the two sides of the ends are in contact, the connecting frame 32 is connected to the processing frame 1, and then maintains the connection with the concentrating frame 41, so that the dust can fall into the concentrating frame 41 to complete the collection and processing of the dust after the separation and blowing. From then on, the effect of effectively controlling the connection state between the connecting frame 32 and the concentrating frame 41 is achieved; the bottom front side of the sliding frame 43 is provided with a front plate 432 for shielding the air inlet pipe 11, and the top of the sliding frame 43 is provided with an air pump 44, and the air outlet of the air pump 44 is connected to an air supply pipe 441, which slides through the sliding frame 43 and extends into the interior of the mounting cylinder 31. The air supply pipe 441 is provided with a column that matches the inner diameter of the upper end of the mounting cylinder 31, so that the two are tightly fitted and used to maintain the sealing effect, so that when the inside of the filter cartridge 33 is backblown, the column follows the operation of the air supply pipe 441 while ensuring the air tightness of the pipeline on the mounting cylinder 31, so that the overall operation can be more stable.

[0036] like Figure 7 and Figure 8 As shown, the driving assembly includes a motor 52, a motor 52 fixedly installed and located inside the assembly frame 2 is also provided on the top of the processing frame 1, and a connecting shaft 53 with a rotatable symmetrical layout, the bottom end of the connecting shaft 53 extends and rotatably passes through the surrounding frame 51, the top end of one side of the connecting shaft 53 is connected to the output end of the motor 52, and the ends of the two connecting shafts 53 are connected by a pulley group, and a group of gears 54 adapted to the layout of the toothed ring 55 are provided on the connecting shaft 53, and the gears 54 are meshed with the corresponding toothed ring 55.

[0037] like Fig. 9 As shown, a locking plate 562 is also included. The connecting plate 56 is slidably penetrated with the locking plate 562. The locking plate 562 is plugged into and matched with the corresponding hinge seat 561 to fix the position of the subsequent knocking rod 57 after folding.

[0038] like Fig.11 and Fig.12As shown, the auxiliary mechanism 6 also includes an electric screw 64 symmetrically installed inside the lower side of the heating frame 61, and a scraper frame 65 is threadedly arranged between the screw bodies of the two electric screws 64. The scraper frame 65 is slidably fitted with the inner wall of the air inlet cylinder 62, and a group of guide sleeves 66 are arranged at intervals on the left and right inside the heating frame 61, and a collecting frame 67 is slidably arranged between the two guide sleeves 66. The collecting frame 67 is abutted against the bottom end of the scraper frame 65. When the scraper frame 65 is located at the top position, the collecting frame 67 is fitted with the bottom end of the air inlet cylinder 62. Through the lifting operation of the scraper frame 65, the dust attached and retained inside the air inlet cylinder 62 can be effectively handled, and the scraping treatment is effectively realized.

[0039] like Figure 1 , Figure 2 and Fig.13 As shown, a steering mechanism 7 is provided at the top of the heating frame 61, and the steering mechanism 7 includes an arc guide rail 71 symmetrically arranged on the top of the heating frame 61, and a conical frame 72 is slidably arranged between the arc guide rails 71 on both sides. The bottom end of the conical frame 72 is connected to the air inlet cylinder 62 through a connecting pipe. The position of the conical frame 72 is adjusted by sliding to achieve effective adjustment of the dust-laden air inlet position.

[0040] like Fig.13 As shown, the steering mechanism 7 also includes a guide frame 73 symmetrically arranged on the conical frame 72, and an insertion rod 74 is penetrated and slidably arranged on both sides of the guide frame 73. An elastic member is arranged between the insertion rod 74 and the corresponding guide frame 73, and the arc guide rail 71 is plugged into and matched with the insertion rod 74 on the same side to fix the position of the conical frame 72.

[0041] like Figure 1-Figure 3 As shown, a grip frame 13 for holding is provided at the bottom of the processing frame 1, and the grip of the grip frame 13 is tilted backward to fit the tilt angle of hand holding.

[0042] When in use, first slide and adjust the conical frame 72 until the conical frame 72 moves to a suitable opening position, and then slide and adjust the insertion rod 74 to insert the insertion rod 74 into the arc guide rail 71, and then start the dust suction pump 3. Through the strong suction force of the dust suction pump 3, the air containing dust in the external environment is sucked into the conical frame 72 due to the suction force, and then the dust-containing air enters the air intake cylinder 62, and the internal moisture in the air is dried by the heating plate 63, so that the dust-containing air entering becomes drier, and then the dried dust-containing air enters the air intake pipe 11, and passes through the filter cartridge 33, and the dust contained therein will adhere to the filter cartridge 33, so as to avoid dust agglomeration caused by excessive humidity, and then the filtered air will continue to be sucked by the dust suction pump 3, pass through the installation cylinder 31 and finally be discharged by the dust suction pump 3, so as to stabilize the dust content in the spraying process, ensure the air environment during operation, and realize effective dust treatment; After the dust treatment is completed, the filter cartridge 33 is cleaned and the air pump 44 and the electric push rod 42 are started synchronously. The electric push rod 42 drives the sliding frame 43 to move downward, so that the baffles 431 on both sides of the sliding frame 43 are separated from the contact shielding of the connecting frame 32, so that the left and right sides of the connecting frame 32 are connected, and then the processing frame 1, the connecting frame 32 and the central frame 41 are connected, and the front plate 432 contacts and blocks the air inlet pipe 11, and the air pump 44 then fills the inside of the installation cylinder 31 with air, and then a strong The airflow impacts the filter cartridge 33, so that the attached dust is separated. At the same time, in order to ensure the stability of the air pressure inside the processing frame 1, during the downward movement of the sliding frame 43, the air pump 44 and the air pipe 441 are moved downward together, until the column of the air pipe 441 moves to a certain distance from the air inlet of the mounting cylinder 31, and then the operation of the sliding frame 43 is stopped, so that the gas injected into the processing frame 1 can be discharged through the gap, ensuring the normal operation of the overall process, thereby achieving the initial cleaning of the dust; Next, the motor 52 is turned on at the same time. The motor 52 drives the rotation of the connecting shafts 53 on both sides synchronously through the pulley group, and then the gear 54 rotates accordingly, so that the gear 54 is meshed with the corresponding toothed ring 55, thereby driving the toothed ring 55 to slide circumferentially along the inner wall of the surrounding frame 51 and the auxiliary track 121, so that the knocking rod 57 follows the operation and contacts the filter cartridge 33, and the knocking rod 57 is used to knock the stubbornly attached dust, so as to effectively clean the stubborn dust; Then, the collecting frame 41 can be pulled to process the dust collected inside, and then the electric screw 64 can be started to drive the scraper frame 65 to move downward along the inner wall of the air inlet cylinder 62 to scrape off the attached dust. As the scraper frame 65 moves downward, it will break away from the contact with the collecting frame 67, and then the collecting frame 67 moves downward, thereby serving as the bottom container of the air inlet cylinder 62 to collect the scraped dust.
