Description

Technical Field

[0001] This invention relates to the field of plastic production technology, specifically to a dry clean dust removal process and treatment device for conductive and antistatic alloy plastics. Background Technology

[0002] In the industrial mass production of conductive and antistatic alloy plastics, dry cleanroom operations involve the simultaneous generation of dust and fine resin impurities. This necessitates a dedicated dust removal device to intercept and purify the airflow, ensuring continuous, dust-free, and compliant operation of the production line. Currently, most conventional dry dust removal equipment in the industry uses a single-airflow cleaning structure, which is poorly suited for cleaning the sticky, fine dust in alloy plastics. Filter cartridges are prone to rapid dust accumulation and clogging, leading to accelerated attenuation of filtration flux. This results in common practical problems such as mismatch between dust removal and operational conditions, cumbersome and laborious cleaning and maintenance, and unstable equipment operation, making it difficult to consistently meet the stringent requirements for stable, dust-free production in high-risk antistatic environments.

[0003] To this end, Chinese Patent No. CN215962775U discloses a dust removal device for the production of conductive and antistatic alloy plastics. It has a pulse backflush device installed at the bottom of the return pipe. When the pulse backflush device is energized, it generates gas. The gas passes through the pipe and the backflush seat to backflush and clean the filter element. This effectively cleans the filter element by blowing it, thus realizing the function of automatic cleaning of the filter element. It eliminates the need for workers to disassemble the filter element for cleaning, improves the cleaning efficiency of the filter element, facilitates the reuse of the filter element, and reduces the cost of plastic dust removal.

[0004] Existing single-pulse reverse-flushing dust collector structures suffer from problems such as limited cleaning force and ineffective removal of stubborn dust. Relying solely on the directional, instantaneous pulsed high-pressure airflow, they lack a physical adhesion and scraping auxiliary structure. This only removes loose surface dust from the filter cartridge, failing to break down the inherent adhesiveness of fine dust particles from alloys and plastics. Stubbornly accumulated dust and embedded debris remain firmly attached to the inner pores of the filter cartridge. The core cause is the lack of a comprehensive, mechanically coupled cleaning structure for airflow cleaning, resulting in insufficient airflow penetration and adhesion. Furthermore, cleaning suffers from dead zones and continuous filtration efficiency degradation. Pulse reverse-flushing is a fixed-point directional blowing operation, leading to uneven force distribution across the filter cartridge's circumference and vertical surfaces. Dust accumulates and builds up in localized blind spots, rapidly causing localized filter cartridge blockage, a surge in air pressure drop, and directly disrupting continuous dust collection and filtration operations.

[0015] A conductive and antistatic alloy plastic dry cleanroom dust removal process includes the following steps: S1. Dust-laden gas is introduced into the treatment box, and the filter cartridges dry-intercept the dust particles in the airflow. The dust adheres and accumulates on the outer surface of the filter cartridges. S2. After dust accumulates on the surface of the filter cartridge, the rotary drive mechanism is activated to drive the scraper to rotate. At the same time, the lifting mechanism controls the scraper to move up and down along the axis of the filter cartridge to peel off the impurities adhering to the surface of the filter cartridge.

[0016] The advantages of this invention compared to the prior art are: 1. This invention, through a processing box, mounting plate, rotary drive mechanism, and lifting mechanism, achieves the function of cleaning impurities adhering to the surface of the filter cartridge by moving scrapers. This ensures stable filter cartridge filtration efficiency during long-term processing, solving the technical problem that traditional processing devices, relying solely on backflushing for cleaning, cannot effectively remove stubborn adhering impurities and affect filtration continuity. It stably achieves the core functions of synchronous dust removal and cleaning of the filter cartridge without dead angles, and long-term circulating dry clean air filtration.

[0017] 2. This invention achieves the function of driving the scraper to rotate along the surface of the filter cartridge through the connecting ring and the rotary driver, thereby achieving the effect of stably scraping off the impurities adhering to the surface of the filter cartridge.

During the scraper blade rotation, the control component drives the scraper blade to periodically rise and fall along the guide frame through the first transmission component, thereby making the scraper blade's trajectory spiral, scraping away impurities adhering to the filter cartridge surface across the entire range and avoiding cleaning dead angles. Simultaneously, while performing scraping and cleaning, pulse backflushing can be performed through the pipes inside the treatment chamber, causing the filter cartridge to expand and the dust to loosen, which, combined with the peeling action of the scraper blade, significantly improves the dust removal efficiency.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 and Figure 2 A conductive antistatic alloy plastic dry clean dust removal device includes a treatment box 1, a mounting plate 2, a rotary drive mechanism 3, and a lifting mechanism 4. The mounting plate 2 is disposed inside the treatment box 1, and a filter cartridge 21 for filtering dust in the gas is provided on the mounting plate 2. The surface of the filter cartridge 21 is provided with a scraper 22 for cleaning the filter cartridge 21. The rotary drive mechanism 3 is used to drive the scraper 22 to rotate to scrape off impurities adhering to the surface of the filter cartridge 21. The lifting mechanism 4 is used to drive the scraper 22 to move up and down along the axis of the filter cartridge 21 during the rotation of the scraper 22.

[0032] This invention, through a processing box 1, mounting plate 2, rotary drive mechanism 3, and lifting mechanism 4, achieves the function of cleaning impurities adhering to the surface of the filter cartridge 21 by moving the scraper 22. This ensures stable filtration efficiency of the filter cartridge 21 during long-term processing, solving the technical problem that traditional processing devices, relying solely on backflushing for cleaning, cannot effectively remove stubborn adhering impurities and affect filtration continuity. It stably achieves the core functions of synchronous dust removal and cleaning of the filter cartridge 21 without dead angles, and long-term circulating dry clean air filtration. Simultaneously, it achieves the practical effects of conductive and anti-static compatibility, minimal clogging and wear of the filter cartridge 21, fully dry and dust-free operation, convenient and labor-saving dust removal and maintenance, stable and durable overall device operation, and clean dust removal with no residue. In actual operation, the entire equipment relies on the treatment box 1 as the main supporting and protective structure. The mounting plate 2 is securely installed in the corresponding position inside the treatment box 1, and the filter cartridge 21 is fixedly mounted on the mounting plate 2. After the dust-containing gas is introduced into the treatment box 1, the filter cartridge 21 directly intercepts and filters various dust impurities mixed in the gas. The dust will continuously adhere to and accumulate on the outer surface of the filter cartridge 21. At this time, the rotary drive mechanism 3 is activated, which drives the scraper 22 attached to the surface of the filter cartridge 21 to rotate smoothly around the outer ring of the filter cartridge 21 throughout the entire process, synchronously linking with the lifting mechanism 4. Throughout the continuous rotation of the scraper 22, it moves up and down at a constant speed along the vertical axis of the filter cartridge 21, allowing the scraper 22 to fully adhere to and slide against the entire outer surface of the filter cartridge 21. This comprehensively scrapes away all kinds of dust and impurities firmly adhering to the outer wall of the filter cartridge 21. The entire process of self-cleaning of the filter cartridge 21 is automated, eliminating the need for frequent manual disassembly and wiping of the filter cartridge 21. This ensures that the entire dust removal device can continuously, stably, and effectively carry out dry dust removal operations, significantly improving the overall quality of dry dust removal operations and extending the service life of the filter cartridge 21 and the entire device.

[0033] Reference Figure 2 and Figure 3 The rotary drive mechanism 3 includes a connecting ring 31 and a rotary driver 32; the connecting ring 31 is rotatably mounted on the mounting plate 2, and the axis of the connecting ring 31 is collinear with the axis of the filter cartridge 21; the scraper 22 is vertically mounted on the connecting ring 31; the rotary driver 32 is mounted on the mounting plate 2, and the rotary driver 32 is used to drive the connecting ring 31 to rotate.

[0034] This invention utilizes a connecting ring 31 and a rotary driver 32 to drive the scraper 22 to rotate along the surface of the filter cartridge 21, achieving a stable effect of scraping away impurities adhering to the surface of the filter cartridge 21. Furthermore, the connecting ring 31 stabilizes the rotation path of the scraper 22, preventing misalignment with the filter cartridge 21 during rotation and ensuring that parts of the filter cartridge 21 remain uncleaned. The scraper is made of flexible, wear-resistant silicone, which avoids scratching the filter cartridge and improves surface adhesion. During cleaning, the rotary driver 32 drives the connecting ring 31 to rotate, which in turn drives the scraper 22 to rotate. The friction between the scraper 22 and the surface of the filter cartridge 21 removes stubborn impurities. During rotation, the lifting mechanism 4 controls the raising and lowering of the scraper 22, further improving the cleaning effect and preventing the formation of annular cleaning dead zones due to deformation or damage to parts of the scraper 22. At the same time, while scraping and cleaning, pulse backflushing can be performed through the pipes in the treatment box 1, causing the filter cartridge 21 to expand and the dust to loosen. The airflow penetrates the filter holes of the filter cartridge 21 to loosen the internal impurities and move them outward. Then, the scraper 22 scrapes off the detached impurities. With the peeling action of the scraper 22, internal and external impurities are cleaned in one go, greatly improving the dust removal power.

[0035] Reference Figures 2 to 4 The lifting mechanism 4 includes a guide frame 41, a first transmission component 42, and a control component 43. The guide frame 41 is disposed on the connecting ring 31, and the scraper 22 is slidably engaged with the guide frame 41. The first transmission component 42 is connected to the scraper 22 in a transmission manner. The control component 43 is disposed on the mounting plate 2. During the rotation of the scraper 22 by the rotary drive mechanism 3, the control component 43 drives the scraper 22 to periodically rise and fall along the guide frame 41 through the first transmission component 42.

[0036] This invention utilizes a guide frame 41, a first transmission assembly 42, and a control assembly 43 to control the raising and lowering of the scraper 22 during its rotational cleaning process, further reducing cleaning dead zones and preventing vertical strip-shaped blind areas from remaining on the surface of the filter cartridge 21. During operation, when the rotary driver 32 drives the connecting ring 31 to rotate, the connecting ring 31 drives the scraper 22 to rotate. During the rotation of the scraper 22, the control assembly 43, through the first transmission assembly 42, drives the scraper 22 to periodically rise and fall along the guide frame 41, thus making the scraper 22's trajectory spiral, scraping away impurities adhering to the surface of the filter cartridge 21 across its entire range and avoiding cleaning dead zones.

[0037] Reference Figures 5 to 7 The scraper 22 is provided with an elastic element 221 and a hinge seat 222; the two ends of the elastic element 221 are respectively connected to the scraper 22 and the guide frame 41; the hinge seat 222 is fixedly connected to the side of the scraper 22, and the scraper 22 is connected to the first transmission assembly 42 through the hinge seat 222.

[0038] This invention achieves the function of controlling the raising and lowering of the scraper blade 22 through the elastic element 221 and the hinge seat 222, and achieves the effect of automatically resetting the scraper blade 22 through the elastic force provided by the elastic element 221. Under the elastic force of the elastic element 221, the scraper blade 22 always has a tendency to move upward and reset. When the rotary driver 32 drives the connecting ring 31 and the scraper blade 22 to rotate, the control component 43 drives the scraper blade 22 to move downward periodically through the first transmission component 42. During the downward movement, the elastic element 221 is stretched by the tension. After the downward movement is completed, the scraper blade 22 moves upward and resets under the elastic force of the elastic element 221. The above actions are repeated during the rotation of the scraper blade 22 to achieve the effect of controlling the periodic raising and lowering of the scraper blade 22.

[0039] Reference Figure 5 and Figure 6 The first transmission component 42 includes a guide rail 421, a slider 422, and a connecting rod 423; the guide rail 421 is disposed on the connecting ring 31; the slider 422 is slidably mounted on the guide rail 421; the two ends of the connecting rod 423 are respectively hinged to the slider 422 and the hinge seat 222; the control component 43 is used to drive the connecting rod 423 to rotate.

[0040] This invention achieves the function of driving the scraper 22 to rise and fall using a transmission assembly via a guide rail 421, a slider 422, and a connecting rod 423. During the rotation of the scraper 22, the control assembly 43 periodically drives the connecting rod 423 to rotate closer to the filter cartridge 21. As the connecting rod 423 rotates, it pulls the slider 422 along the guide rail 421, and the support provided by the connecting rod 423 pushes the scraper 22 downwards along the axis of the filter cartridge 21, causing the elastic element 221 to extend accordingly. When the scraper 22 reaches the end of its stroke, the control assembly 43 stops driving the rotation of the connecting rod 423, and the scraper 22 returns to its original position under the elastic force of the elastic element 221, completing one lifting and lowering action of the scraper 22.

[0041] Reference Figure 3 , Figure 4 , Figure 8 and Figure 9 The control component 43 includes a connecting frame 431, an extension rod 432, and a support 433. The connecting frame 431 is connected to the connecting rod 423. The extension rod 432 is connected to the connecting frame 431, and a fixed shaft 4321 extending radially along the filter cartridge 21 is provided at one end of the extension rod 432 away from the connecting frame 431. The support 433 is fixedly installed on the mounting plate 2, and an oblique protrusion 4331 is provided on the support 433. During the rotation of the scraper 22 around the axis of the filter cartridge 21, when the fixed shaft 4321 contacts the oblique protrusion 4331, it is squeezed and drives the connecting rod 423 to rotate.

[0042] This invention achieves the function of periodically driving the scraper 22 to rise and fall during rotation through the connecting frame 431, the extension rod 432, and the support 433. During the rotation of the scraper 22 around the axis of the filter cylinder 21, when the fixed shaft 4321 contacts the inclined surface of the inclined protrusion 4331, it is squeezed by the inclined surface and moves away from the mounting plate 2. This force, transmitted through the connecting rod 423, drives the scraper 22 downwards. During this downward movement, the scraper 22 pulls the slider 422 towards the scraper 22 via the connecting rod 423, thereby causing the connecting rod 423 to rotate. The rotating connecting rod 423 then drives the extension rod 432 to move synchronously, thus controlling the movement of the fixed shaft 4321 on the extension rod 432. When the fixed shaft 4321 completely passes the inclined surface of the inclined protrusion 4331, it loses its squeezing force, and the scraper 22 moves upwards and resets under the elastic force of the elastic element 221, completing one lifting and lowering action.

[0043] Reference Figures 5 to 7 The filter cartridge 21 and the connecting ring 31 are both provided in twos; the mounting plate 2 is provided with a second transmission component 33, and the two connecting rings 31 are connected by transmission through the second transmission component 33; the rotary driver 32 drives the two connecting rings 31 to rotate synchronously through the second transmission component 33.

[0044] This invention enables simultaneous scraping and cleaning of two filter cartridges 21. To improve the dust removal efficiency of the treatment chamber 1, two filter cartridges 21 are provided, and each filter cartridge 21 is equipped with a corresponding scraper 22 and connecting ring 31. After the rotary driver 32 is started, the rotary driver 32 drives the two connecting rings 31 to rotate synchronously through the second transmission component 33. The two connecting rings 31 drive the scraper 22 mounted on them to rotate, thereby performing a synchronous cleaning action on the two filter cartridges 21.

[0045] Reference Figure 5 and Figure 10 The second transmission assembly 33 includes a gear ring 331, a rotating shaft 332, and a transmission belt 334. There are two gear rings 331, which are respectively sleeved on two connecting rings 31. There are two rotating shafts 332, which are rotatably mounted on the mounting plate 2 and are respectively positioned corresponding to the two connecting rings 31. Each rotating shaft 332 is sleeved with a rotating gear 3321 that meshes with the corresponding gear ring 331, and the two rotating shafts 332 are connected by the transmission belt 334.

[0046] This invention achieves the function of connecting two connecting rings 31 through a gear ring 331, a rotating shaft 332, and a transmission belt 334, enabling the rotary driver 32 to drive the two connecting rings 31 to rotate synchronously. In operation, after the rotary driver 32 is activated, it drives one of the rotating shafts 332 to rotate. This shaft 332 drives the rotating gear 3321 to rotate, and simultaneously drives the other rotating shaft 332 to rotate synchronously via the transmission belt 334. When the rotating gear 3321 rotates, it drives the gear ring 331, which in turn drives the connecting ring 31 to rotate synchronously. The connecting ring 31 then drives the scraper 22 to rotate synchronously, and the scraper 22 performs the subsequent scraping and cleaning work.

[0047] Reference Figure 3 and Figure 4 The mounting plate 2 is provided with a protective shell 23 for isolating the second transmission component 33.

[0048] This invention achieves the function of enclosing and protecting the gear ring 331, rotating shaft 332, rotating gear 3321, and transmission belt 334 through the protective shell 23. In operation, dusty air is introduced into the processing chamber 1. To prevent dust from accumulating on the transmission structure and affecting transmission, the protective shell 23 is provided to isolate the second transmission component 33. Simultaneously, the rotary driver 32 also uses a motor with a protective structure to prevent dust and scraped impurities from adhering to the transmission structure, ensuring the stability of the device's operation.

[0049] Reference Figures 1 to 4 A conductive and antistatic alloy plastic dry cleanroom dust removal process includes the following steps: S1. The dust-laden gas is introduced into the treatment box 1, and the filter cartridge 21 dry intercepts the dust particles in the airflow. The dust adheres and accumulates on the outer surface of the filter cartridge 21. S2. After dust accumulates on the surface of the filter cartridge 21, the rotary drive mechanism 3 is activated to drive the scraper 22 to rotate. At the same time, the lifting mechanism 4 controls the scraper 22 to rise and fall along the axis of the filter cartridge 21 to peel off the impurities adhering to the surface of the filter cartridge 21.

[0050] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
