Technical Field
[0001] This invention relates to the technical field of dust removal equipment for ink production, specifically to an intelligent dust removal device and method for ink production. Background Technology
[0002] Intelligent dust removal equipment for ink production is a dust purification and treatment device specifically designed for ink production scenarios, integrating automated control and intelligent monitoring functions. It can handle dust generated during the feeding, mixing, and grinding processes of pigments, fillers, and other powder raw materials.
[0003] Referring to Chinese Patent Publication No. CN112588031B, a dust removal device for ink production and its usage method are disclosed. The device includes an air pump, a silencing device, a dust removal device, and an adjusting device. The air pump has a silencing device on its outer side, a base fixedly connected to its bottom, a controller fixedly connected to the left end of the base, a sleeve slidably connected to the outer side of the air pump's inlet pipe, and the dust removal device connected to the other end of the sleeve. An adjusting device is fixedly connected to the left side of the top of the air pump. In this invention, by setting a handle, a driving bevel gear, and a threaded shaft, the fixed connection between the handle and the driving bevel gear, the meshing connection between the driving bevel gear and the driven bevel gear, the sliding connection between the slider and the support frame, and the helical connection between the threaded shaft and the slider, the height of the dust removal mechanism can be manually adjusted according to needs during use, increasing the device's applicability and facilitating its storage and retrieval, thus saving space.
[0004] Large dust particles (such as agglomerated pigments and resin particles) in ink production can directly impact and wear down filter bags and filter cartridges if they enter the main filter. They can also easily clog the pores of the filter media. This can be mitigated by installing a coarse filter at the feed inlet before the filter assembly. However, during ink production, the amount of dust is large, and ink dust easily agglomerates and adheres to the surface of the filter media to form a hard layer, which quickly clogs the filter pores. Timely cleaning is required. In high-capacity production (daily output ≥ 1 ton) or dust-concentrated processes such as feeding / grinding, inspection and cleaning are required every 2-3 hours. This leads to frequent start-ups and shutdowns of the production line, making continuous processing impossible. Each cleaning takes 10-30 minutes, reducing production efficiency.

One end of each moving rod is connected to a driving plate, and one side of each driving plate is fixedly connected to the side of a first sealing plate or a second sealing plate.
[0011] Preferably, the air control device includes: an outer box, which is fixedly connected to the dust removal assembly via a fixing plate; an inner box is connected to the inner wall of the outer box; two top holes are opened through the top of the outer box, each of which is connected to an air inlet pipe; a channel is opened through one side of the inner box, one end of which passes through the outer box and is connected to a fan outside the outer box; the inner wall of the outer box is connected to one side of the inner box via a partition, which divides the inner cavity of the outer box into an upper cavity and a lower cavity, the upper cavity being connected to the top holes; a first air vent is opened through one side of the inner box, which is connected to the upper cavity; a second air vent is opened through the other side of the inner box, which is connected to the lower cavity; a main air vent is opened through one side of the outer box, which is connected to an inner air duct located in the lower cavity; a differential pressure seal is connected to the side of the inner air duct; a baffle plate is slidably connected to the inner wall of the inner box, the baffle plate being connected to the telescopic end of a hydraulic cylinder; and the fixed end of the hydraulic cylinder is fixedly connected to the outer side of the outer box.
[0012] Preferably, the differential pressure sealing element includes: a movable plate located in the lower cavity, with several second springs evenly distributed in a circumferential direction on the edge of the movable plate near the inner air duct, one end of each second spring being connected to a connecting plate, one end of the connecting plate being fixedly connected to the side of the inner air duct, and a windward groove being provided on the side of the movable plate near the inner air duct.
[0013] Preferably, the pressure sealing cleaning device includes: a pipe, one end of which is connected to the main air outlet, and the other end of which is connected to the air blowing box. When the cylindrical drum rotates to the cleaning position, fixed end plates are provided at both ends of the cylindrical drum. One end of the air blowing box is fixedly connected to a fixed end plate, and the other fixed end plate is fixedly connected to the dust collection pipe. One side of each fixed end plate is connected to a moving end plate through an elastic plate, and one side of each fixed end plate is connected to the moving end plate through a third spring. The fixed end plate, the moving end plate, and the elastic plate form a pressure box, and the inner cavity of the pressure box is connected to the lower cavity through an air supply pipe.
[0014] Preferably, when the baffle plate moves to the first position, the baffle plate is located at one end of the inner box, the first air vent is connected to the upper cavity, and the second air vent is sealed. When the baffle plate moves to the second position, the baffle plate is located at the other end of the inner box, the second air vent is connected to the lower cavity, and the first air vent is sealed.

When the fan speed is at the second speed, the baffle plate is separated from one end of the inner air duct, and the inner air duct is connected to the pipeline.
[0015] A smart dust removal method for ink production is applied to a smart dust removal device for ink production. Multiple truncated cones are rotated synchronously via a rotating device. One cone rotates to the filtration station, and the baffle plate moves to the first position with the extension and retraction end of the hydraulic cylinder. Air enters the pneumatic compressor, and the first and second sealing plates move simultaneously towards the center of the cone, sealing the gaps at the connection between the cone and the first and second feed pipes. The flow rates at both ends of the cone are measured in real time by the first and second flow sensors. When the flow rate difference exceeds a set threshold or the flow rate decreases by 30%, the filter plate is determined to be clogged, and the ink production device is briefly shut down. The cone at the filtration station rotates to the cleaning station, the baffle plate moves to the second position, and the fan is set to speed one. A pressure-sealing cleaning device seals both ends of the cone at the cleaning station, and the fan is set to speed two. The inner air duct is connected to the lower cavity, and impurities on the filter plate are blown off by the airflow.
[0016] Beneficial Effects: This invention provides an intelligent dust removal device and method for ink production. Compared with existing technologies, it has the following beneficial effects: 1. The multi-cylinder rotating design allows for parallel filtration and cleaning, eliminating the need for overall machine shutdown for cleaning. Automated switching of workstations, sealing, and cleaning processes reduces manual operation time and improves production continuity. Targeted cleaning of clogged filter plates eliminates the need for complete replacement, extending filter plate lifespan. Automatic cleaning reduces the time and labor costs of manual disassembly and maintenance, minimizing equipment wear caused by manual operation.
[0017] 2. A stepper motor drives the truncated cone to rotate synchronously. After station switching, the hydraulic cylinder and blower automatically trigger the sealing process without manual intervention. From the positioning of the baffle plate to the snap-fit and compression sealing of the sealing plate, the entire process is linked and responds in a coordinated manner, quickly matching the start-up rhythm of the filtration station. The first and second sealing plates snap into their corresponding sealing slots, achieving mechanical positioning and elastic compression for dual fixation, preventing seal misalignment. The middle of the sealing plate uses an elastic material, which is compressed through air pressure to accommodate minor errors at the connection point, resulting in a high degree of sealing fit and effectively preventing air and material leakage. The initial spacing between the sealing plates is greater than the length of the truncated cone to avoid collisions with the cone during station switching, protecting equipment components. The elastic sealing material compresses and seals, eliminating hard contact wear, extending the service life of the sealing plate, the truncated cone, and the feed pipe, while also preventing material contamination due to hard contact during sealing.
[0018] 3. After blockage, the production unit is briefly shut down, and the workstation is switched simultaneously via a rotating device. Cleaning and subsequent filtration can be carried out in parallel, reducing overall downtime. The system automatically completes baffle switching, sealing, and purging. The first pressure setting completes the pressure sealing, while the second high-pressure setting focuses on concentrated purging. Sealing before high-pressure cleaning prevents impurities from scattering and causing contamination. The airflow is directly directed to the back of the filter plate, specifically removing impurities and guiding them into the dust collection pipe for a more thorough cleaning. The first low-pressure stage avoids direct impact of high pressure on the sealing structure, while the second high-pressure stage focuses on purging; this tiered design reduces wear on equipment components. Automatic sealing and directional dust collection prevent impurities from contaminating other workstations or equipment during cleaning, reducing maintenance costs and material losses.

[0050] A smart dust removal method for ink production is applied to a smart dust removal device for ink production. Multiple frustum cylinders 23 are synchronously rotated via a rotating device 2. When one frustum cylinder 23 rotates to the filtration station, the baffle plate 46 moves to a first position with the extension / retraction end of the hydraulic cylinder 47. Air enters the pneumatic compressor, and the first sealing plate 32 and the second sealing plate 33 simultaneously move towards the center of the frustum cylinder 23, sealing the gaps at the connections between the frustum cylinder 23 and the first feed pipe 12 and the second feed pipe 13. The method is verified by a first flow sensor and a second flow sensor. The flow sensor measures the flow rate at both ends of the frustum 23 in real time. When the flow rate difference exceeds the set threshold or the flow rate decreases by 30%, the filter plate 24 is determined to be blocked. The ink production device is temporarily shut down, the frustum 23 at the filtration station rotates to the cleaning station, the baffle plate 46 moves to the second position, the fan 34 is in the first gear, the pressure sealing cleaning device 5 seals both ends of the frustum 23 at the cleaning station, the fan 34 is in the second gear, the inner air duct 44 is connected to the lower cavity, and the impurities on the filter plate 24 are blown off by the air blowing action 54.
[0051] In use, the small opening of the frustum-shaped cylinder 23 is connected to the first feed pipe 12, and the large opening is connected to the second feed pipe 13. A filter plate 24 is connected to the large opening end of the frustum-shaped cylinder 23. The height difference between the two ends of the frustum-shaped cylinder 23 eliminates the need for an additional ash hopper, creating a bag-like space. The large bottom space and low height of the large opening end of the frustum-shaped cylinder 23 provide storage space for impurities blocked by the filter plate 24. Utilizing the height difference of the frustum-shaped cylinder 23 and the space at the large opening end replaces a separate ash hopper, reducing the number of equipment parts. The design of a small inlet for air intake and a large opening for filter plate 24 guides the dust-laden airflow to slow down, helping large dust particles to be accurately intercepted by the filter plate 24 under the impact of gravity and airflow. The large bottom space and low height of the large opening end provide ample storage space for impurities, resulting in higher collection efficiency and reduced dust residue. During the rotation of the frustum-shaped cylinder 23, impurities are confined to the large opening end due to their own gravity and the shape of the internal space, preventing them from falling.
[0052] The rotating device 2 is started, and the rotating end of the stepper motor 21 drives all the frustum cylinders 23 to rotate synchronously through the rotating plate 22. One frustum cylinder 23 rotates to the filtration station. At this time, the distance between the first sealing plate 32 and the second sealing plate 33 is greater than the length of the cylinder. The piston rod of the hydraulic cylinder 47 slides to the first position with the baffle plate 46. The first air outlet 61 is connected to the upper cavity, and the second air outlet 62 is sealed. The first fan 34 is started, and the airflow in the upper cavity enters the two air chambers 313 in sequence through the top hole 42 and the two air inlet pipes 311. The air pressure in the air chamber 313 increases, and the air plate slides along the inner wall of the air chamber 313 toward the center of the frustum cylinder 23. The first spring 314 is stretched, and the air plate moves in sequence with the moving rod 316, the driving plate 491317, the first sealing plate 32, and the second sealing plate 33. The first sealing plate 32 engages with the second sealing groove 27, and the second sealing plate 33 engages with the first sealing groove 26. The middle parts of the first sealing plate 32 and the middle parts of the second sealing plate 33 are both made of elastic sealing material. As the first sealing plate 32 and the second sealing plate 33 approach the center of the frustum cylinder 23, the middle parts of the first sealing plate 32 and the middle parts of the second sealing plate 33 are squeezed and seal the gap at the connection between the frustum cylinder 23 and the first feed pipe 12 and the second feed pipe 13.
[0053] Under normal conditions, the inlet and outlet flow rates of the frustum-shaped filter 23 are basically the same. Due to the resistance of pipe 51 and the accuracy of the sensors, an error of ±5% is allowed. After dust adheres to the filter media, the airflow channel narrows, the inlet flow rate remains unchanged or decreases slightly, and the outlet flow rate decreases significantly, forming a flow difference between the inlet and outlet. The more severe the blockage, the greater the flow difference and the more obvious the attenuation of the outlet flow rate. When the error reaches 9%, it is considered to have reached the set threshold. The inlet flow rate Q1 is recorded in real time by the first flow sensor, and the outlet flow rate Q2 is recorded in real time by the second flow sensor. The initial difference ΔQ0 = Q1 - Q2 is calculated. During operation, the inlet and outlet flow rates are monitored in real time, and the real-time difference ΔQ = real-time Q1 - real-time Q2 is calculated. When ΔQ ≥ 20% Q1 or ΔQ ≥ 3 times ΔQ0, it is judged as moderate blockage; when ΔQ ≥ 30% Q1, it is judged as severe blockage, which requires immediate cleaning.
[0054] When the flow rate difference exceeds the set threshold or the flow rate decreases by 30%, the filter plate 24 is determined to be clogged. The ink production device is temporarily shut down, and the rotating device 2 drives all the frustum cylinders 23 to rotate. The frustum cylinder 23 at the filtration station rotates to the cleaning station. The telescopic end of the hydraulic cylinder 47 moves the baffle plate 46 to the second position, and the second air outlet 62 connects to the lower cavity, while the first air outlet 61 is sealed. At this time, the fan 34 is in the first gear, and the air pressure in the lower cavity cannot compress the third spring 57 and separate the baffle plate 46 from the inner air duct 44 within a predetermined time. The airflow in the lower cavity connects to the inner cavity of the pressure box through the air supply pipe. The air pressure in the pressure box increases, the elastic plate 56 stretches, and the moving end plate 55 approaches one end of the frustum cylinder 23. Finally, the moving end plate 55 presses against the edge of one end of the frustum cylinder 23, and the pressure sealing cleaning device 5 seals both ends of the frustum cylinder 23 at the cleaning station. Adjust the fan speed from 34 to 2, connecting the inner duct 44 to the lower chamber. The air pressure in the lower chamber increases rapidly, stretching the third spring 57. The baffle plate 46 separates from the inner duct 44, and most of the airflow in the lower chamber flows through the inner duct 44, main air outlet 63, pipe 51, and blower box 52 towards the back of the filter plate 24, blowing away impurities 54. After each cleaning, promptly clean the impurities in the dust collection pipe 54. Ensure all devices are grounded for static electricity prevention.
[0055] The cleaning process is initiated only after a blockage is detected, ensuring targeted cleaning without wasting energy or production time. Production is briefly shut down after a blockage, and the workstation is switched simultaneously via the rotating device 2, allowing cleaning and subsequent filtration to proceed in parallel, reducing overall downtime. The hydraulic cylinder 47, fan 34, and pressure-sealing cleaning device 5 work in tandem to automatically complete the switching, sealing, and purging of the baffle plate 46, ensuring a smooth process without manual intervention. The first pressure setting completes the pressure sealing, while the second high-pressure setting focuses on concentrated purging, sealing first and then high-pressure cleaning to prevent impurities from scattering and contaminating the surface. Airflow is directly directed towards the back of the filter plate 24, specifically removing impurities and guiding them into the dust collection pipe 54, resulting in a more thorough cleaning and faster restoration of the filter plate 24's filtration performance. The first low-pressure stage avoids direct impact of high pressure on the sealing structure, while the second high-pressure stage focuses on purging; this tiered design reduces wear on equipment components. Automatic sealing and directional dust collection prevent impurities from contaminating other workstations or equipment during cleaning, reducing maintenance costs and material waste.
