Description

Technical Field

[0001] This invention relates to the field of textile processing technology, and in particular to a device and method for preventing the settling of flying fibers in textile workshops to prevent air pollution. Background Technology

[0002] During the spinning and weaving processes in textile workshops, the high-speed operation of textile equipment continuously generates a large amount of lint. This lint, mostly composed of fiber fragments, easily suspends in the workshop atmosphere, causing not only air pollution within the workshop and affecting the cleanliness of the production environment, but also health problems caused by workers inhaling it. In addition, some lint is flammable, potentially posing a fire hazard. Furthermore, if the lint is dispersed outside the workshop by airflow, it can also pollute the surrounding atmospheric environment. Therefore, controlling lint pollution in textile workshops is a necessary measure to ensure production safety, worker health, and environmental quality.

[0003] Existing technologies for treating airborne fluff pollution have significant drawbacks. Structurally, most employ direct water spraying for sedimentation. This method has a limited spray range and poor uniformity. Some fluff clumps and adheres to the surface of textile equipment due to water spraying, affecting equipment operation and failing to collect the fluff centrally. The wet sludge formed after sedimentation and mixing with water easily breeds bacteria on the ground, causing secondary pollution and making subsequent cleaning difficult. Furthermore, these technologies lack adaptability, operating at fixed intervals without a high-precision fluff density detection mechanism. They cannot dynamically adjust the operating status based on real-time pollution conditions. When fluff density exceeds a threshold, delayed treatment leads to pollution accumulation, while low density results in wasted energy. Therefore, this invention proposes a fluff sedimentation device and method for preventing air pollution in textile workshops to address the problems existing in the prior art. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a device and method for preventing the settling of flying catkins in textile workshops. This method not only avoids secondary diffusion of flying catkins during the collection process but also reduces the difficulty of subsequent cleaning and transportation through briquetting treatment, effectively blocking the transmission path of flying catkin pollution from a physical perspective.

[0005] To achieve the objective of this invention, the invention is implemented through the following technical solution: a lint settling device for preventing air pollution in textile workshops, comprising a gantry frame and an atomizing tube, wherein a movable frame is movably mounted on the gantry frame, and a moving cart is movably mounted at the bottom of the movable frame, wherein the moving cart is provided in several groups, and an absorption tube is movably mounted on both sides below the moving cart, wherein a conveying pipe is provided inside the movable frame, and a number of collection hoppers are provided on the conveying pipe, wherein a vacuum cleaner is connected to the top of the collection hopper, and a stretching hose is connected between the absorption tube and the input end of the vacuum cleaner;

[0006] One end of the bottom of the conveying pipe is provided with a discharge pipe that is compatible with the top of the atomizing pipe. The bottom of the atomizing pipe is provided with a compression chamber. The absorption pipe is used to absorb the flying fluff into the collection hopper. The flying fluff is conveyed to the atomizing pipe through the conveying pipe for spraying and settling. The compression chamber is used to compress the humidified and settled flying fluff into clumps.

[0007] A further improvement is that: the bottom of the gantry frame is provided with a support frame, and the bottom of the support frame is fixed to the ground of the textile workshop; both the support frame and the gantry frame are provided with reinforcing ribs inside; the top of the gantry frame is provided with a drive guide rail, and the movable frame moves through the drive guide rail.

[0008] A further improvement is that: guide grooves are provided on the lower sides of both sides of the movable frame, drive wheels are provided on both sides of the moving vehicle, the drive wheels are adapted to the guide grooves, and a reinforcing rod is provided on the upper inner side of the movable frame, and multiple sets of reinforcing rods are provided.

[0009] A further improvement is that: both ends of the bottom of the vehicle are provided with axle plates, the absorption tube is rotatably installed on the inner side of the axle plate, a reduction motor is provided on one side of the axle plate, and the output end of the reduction motor is connected to the absorption tube.

[0010] A further improvement is that the conveying pipe is equipped with a spiral blade shaft that rotates inside, and a motor is provided at one end of the conveying pipe, with the output end of the motor connected to the spiral blade shaft.

[0011] A further improvement is that splicing blocks are provided on both sides of the bottom of the discharge pipe, and splicing grooves are provided on both sides of the top of the atomizing pipe. The splicing blocks and splicing grooves are adapted to each other, and the discharge pipe and the atomizing pipe are connected.

[0012] Further improvements include: an atomizing nozzle is provided on one side of the atomizing tube, and multiple sets of atomizing nozzles are provided; the output end of the atomizing nozzle is connected to the atomizing tube; a water pipe is connected between the input end of the atomizing nozzle and the water source; a pneumatic cylinder is provided at one end of the compression chamber; the output end of the pneumatic cylinder extends into the interior of the compression chamber and is connected to a pressure plate; an opening and closing door is provided at the end of the compression chamber away from the pneumatic cylinder; a strainer is provided at the bottom of the compression chamber; and the bottom of the compression chamber is connected to a sewer.

[0013] Further improvements include a control system comprised of a main controller, a high-precision particulate matter detection sensor, and a data storage unit. The high-precision particulate matter detection sensor is installed at the air inlet of the absorption pipe to collect real-time data on the density of flying fluff in the airflow during fluff absorption. The main controller interacts with the high-precision particulate matter detection sensor, the vacuum cleaner, the drive rail, and the motor signals of the conveying pipe. The data storage unit stores operating parameters and detection data. The main controller is preset with an initial operating interval N and a fluff density threshold ρ0, and dynamically controls the operating interval of the moving frame using the following algorithm formula:

[0014] When the real-time detected density of flying catkins ρ≤ρ0, the moving frame maintains its initial operating interval, i.e., T=N. When the real-time detected density of flying catkins ρ>ρ0, the operating interval of the moving frame is shortened according to formula (①):

[0015] T=N×[1-k×(ρ-ρ0) / ρ0](①)

[0016] Where T is the actual operating interval of the mobile frame, in hours; N is the initially set operating interval of the mobile frame, in hours, calibrated based on the workshop's typical fluff generation, with a value range of 0.5 ≤ N ≤ 2; ρ is the fluff density collected in real time by a high-precision particulate matter detection sensor, in mg / m³. 3 ρ0 is the preset pollutant density threshold for airborne catkins, in mg / m³. 3 The value range is 50≤ρ0≤100; k is the influence coefficient of the density of flying fluff, which is calibrated according to the workshop space volume V and the number of textile equipment Q. The calculation formula is k=0.1+0.02×(Q / V), and the value range is 0.1≤k≤0.8.

[0017] A further improvement is made in that: the main controller is preset with M consecutive times exceeding the threshold and an initial running speed v0. When the average density of the flying catkins detected M times consecutively is greater than ρ0, the main controller synchronously adjusts the running speed and running interval of the moving frame. The specific control logic is as follows:

[0018] Calculation of the average density of flying catkins over M consecutive periods:

[0019] ρ_avg=(ρ1+ρ2+...+ρ_M) / M(②)

[0020] Adjustment of single-process operation speed of the mobile frame:

[0021] v=v0×[1+m×(ρ_avg-ρ0) / ρ0](③)

[0022] Secondary adjustment of the mobile frame operating interval: temporarily increase the value of k in formula (①) by 20%, that is, k'=k×1.2, and substitute it into formula (①) to calculate the new interval T';

[0023] In formulas (②) and (③), ρ_avg is the average density of the flying catkins from M consecutive measurements, in mg / m³. 3 ρ_i represents the real-time pollen density from the i-th measurement, where i = 1, 2, ..., M, and the unit is mg / m³. 3M represents the number of consecutive threshold judgments, set according to the equipment response sensitivity, with a value range of 3≤M≤5; v represents the actual operating speed of the mobile frame, in m / min; v0 represents the initial operating speed of the mobile frame, in m / min, calibrated according to the gantry length, with a value range of 0.3≤v0≤0.8; m represents the speed influence coefficient, calibrated according to the suction volume Q_wind of the absorption pipe, calculated by the formula m=0.05+0.01×(Q_wind / 100), with a value range of 0.05≤m≤0.5;

[0024] When the main controller detects ρ_avg≤ρ0 for three consecutive times, it automatically restores the initial k value and the initial running speed v0.

[0025] The method for using a lint settling device to prevent air pollution in textile workshops includes the following steps:

[0026] Adjust the position of each moving car so that it is positioned above the textile equipment;

[0027] The driving mobile frame moves along the gantry frame;

[0028] When the vacuum cleaner is running, it provides suction to the absorption tube by extending the hose, and the lint is absorbed by the absorption tube and enters the collection hopper.

[0029] When a process returns to its origin, the discharge pipe and the atomizing pipe are connected;

[0030] The conveying pipe operates, transporting the flying fluff from multiple collection hoppers to the discharge pipe, where it falls into the atomizing pipe;

[0031] The humidified and settled fluff is sprayed inside the atomizing tube and then falls into the compression chamber to compress the fluff, thereby preventing pollution.

[0032] The beneficial effects of this invention are as follows:

[0033] 1. This invention combines flexible coverage with closed-loop pollution treatment. It achieves large-scale coverage of the workshop through the sliding cooperation of the gantry and the mobile frame. Multiple sets of mobile carts with independently adjustable positions can accurately correspond to the top of different textile equipment. The absorption pipe, collection hopper, conveying pipe, atomizing pipe and compression chamber are connected in sequence to form a complete process of fluff absorption, centralized conveying, spraying and settling, and briquetting disposal. This not only avoids secondary diffusion of fluff in the collection stage, but also reduces the difficulty of subsequent cleaning through briquetting treatment, effectively blocking the transmission path of fluff pollution from a physical level.

[0034] 2. This invention achieves precision and energy saving in pollution control. High-precision sensors collect the density of flying catkins in real time, and trigger the operation interval adjustment with a preset threshold ρ0 as the core. Combined with the k value calibrated by the workshop space volume and the number of equipment, the interval adjustment is made to fit the actual pollution generation pattern. When the pollution is low, the initial interval N is maintained to avoid waste, and when the pollution is high, the interval is shortened to increase the treatment frequency. This ensures energy consumption optimization when the pollution does not exceed the standard, and can respond to the upward trend of pollution in a timely manner to avoid pollution accumulation.

[0035] 3. This invention further enhances the system's ability to cope with continuous pollution. By eliminating accidental interference through the average density ρ_avg of M consecutive times, the persistence of pollution can be accurately determined. Combined with the m value calibrated by the suction volume of the absorption pipe, the speed adaptability is improved. With the temporary increase of the k value and the shortening of the secondary interval, a dual enhancement mechanism of "frequency + efficiency" is formed. At the same time, the parameter recovery logic after pollution is alleviated is set up to ensure rapid processing during high pollution and prevent equipment from being worn out by long-term high-load operation, thus balancing the treatment effect and the economic efficiency of the equipment.

[0047] The bottom of the gantry frame 1 is provided with a support frame 12, and the bottom of the support frame 12 is fixed to the ground of the textile workshop to improve stability. Both the support frame 12 and the gantry frame 1 are provided with reinforcing ribs 14 to improve strength.

[0048] Guide grooves 15 are provided on the lower sides of both sides of the movable frame 2, and drive wheels 16 are provided on both sides of the moving carriage 3. The drive wheels 16 are adapted to the guide grooves 15. A reinforcing rod 17 is provided on the upper inner side of the movable frame 2, and multiple sets of reinforcing rods 17 are provided. In use, the motor drives the drive wheels 16 to rotate, driving the moving carriage 3 to move along the guide grooves 15.

A reduction motor 19 is provided on one side of the axle plate 18, and the output end of the reduction motor 19 is connected to the absorption tube 4.

[0052] Atomizing nozzles 23 are provided on one side of the atomizing tube 10, and multiple sets of atomizing nozzles 23 are provided. The output end of the atomizing nozzles 23 is connected to the atomizing tube 10, and a water pipe is connected between the input end of the atomizing nozzles 23 and the water source.

Water is sprayed into the atomizing tube 10 through the atomizing nozzles 23, causing the flying fluff to settle.

[0053] It also includes a control system, which consists of a main controller, a high-precision particulate matter detection sensor, and a data storage unit. The high-precision particulate matter detection sensor is installed at the air inlet of the absorption pipe 4 to collect the density of flying fluff in the airflow during real-time absorption. The main controller interacts with the high-precision particulate matter detection sensor, the vacuum cleaner 8, the drive rail 13, and the motor signals of the conveying pipe 5. The data storage unit is used to store operating parameters and detection data. The main controller presets an initial operating interval N and a flying fluff density threshold ρ0, and dynamically controls the operating interval of the moving frame 2 using the following algorithm formula:

[0054] When the real-time detected density of flying catkins ρ≤ρ0, the mobile frame 2 maintains its initial operating interval, i.e., T=N. When the real-time detected density of flying catkins ρ>ρo, the operating interval of the mobile frame 2 is shortened according to formula ①:

[0055] T=N×[1-k×(ρ-ρ0) / ρ0]①

[0056] Where T is the actual operating interval time of the mobile frame 2, in hours; N is the initially set operating interval time of the mobile frame 2, in hours, calibrated according to the workshop's normal fluff generation, with a value range of 0.5 ≤ N ≤ 2; ρ is the fluff density collected in real time by the high-precision particulate matter detection sensor, in mg / m³. 3 ρ0 is the preset pollutant density threshold for airborne catkins, in mg / m³. 3 The value range is 50≤ρ0≤100; k is the influence coefficient of fluff density, calibrated according to the workshop space volume V and the number of textile equipment Q, and the calculation formula is k=0.1+0.02×(Q / V), with a value range of 0.1≤k≤0.8. This achieves precise and energy-saving pollution control. High-precision sensors collect fluff density in real time, triggering operation interval adjustments based on a preset threshold ρ0. Combined with the k value calibrated according to the workshop space volume and the number of equipment, the interval adjustment closely matches the actual pollution generation pattern. During low pollution, the initial interval N is maintained to avoid waste, while during high pollution, the interval is shortened to increase the processing frequency. This ensures energy optimization when pollution does not exceed standards and timely response to rising pollution trends to prevent pollution accumulation.

[0057] The main controller is preset with M consecutive times exceeding the threshold and an initial operating speed v0. When the average density of the flying catkins detected M times consecutively is greater than ρ0, the main controller synchronously adjusts the operating speed and interval of the moving frame 2. The specific control logic is as follows:

[0058] Calculation of the average density of flying catkins over M consecutive periods:

[0059] ρ_avg=(ρ1+ρ2+...+ρ_M) / M②

[0060] Adjustment of single-process running speed for mobile rack 2:

[0061] v=v0×[1+m×(ρ_avg-ρ0) / ρ0]③

[0062] Secondary adjustment of the running interval of mobile frame 2: temporarily increase the value of k in formula ① by 20%, that is, k' = k × 1.2, and substitute it into formula ① to calculate the new interval T';

[0063] In formulas ② and ③, ρ_avg is the average density of the flying catkins from M consecutive measurements, in mg / m³. 3 ρ_i represents the real-time pollen density from the i-th measurement, where i = 1, 2, ..., M, and the unit is mg / m³. 3; M is the number of consecutive over-threshold determinations, set according to the device response sensitivity, with a value range of 3 ≤ M ≤ 5; v is the actual running speed of the moving frame 2, in m / min; v0 is the initial running speed of the moving frame 2, in m / min, calibrated according to the length of the gantry 1, with a value range of 0.3 ≤ v0 ≤ 0.8; m is the speed influence coefficient, calibrated according to the air volume Q of the absorption tube 4, and the calculation formula is m = 0.05 + 0.01×(Q / 100), with a value range of 0.05 ≤ m ≤ 0.5;

[0064] When the main controller detects ρ_avg ≤ ρ0 three times consecutively, it automatically restores the initial k value and the initial running speed v0. This further enhances the system's ability to cope with continuous pollution. By excluding accidental interference through M consecutive density averages ρ_avg, it accurately determines the persistence of pollution; combined with the m value calibrated according to the air volume of the absorption tube 4 to improve speed adaptability, and the secondary interval with a temporarily increased k value is shortened, forming a "frequency + efficiency" double enhancement mechanism; at the same time, the parameter restoration logic after pollution mitigation is set, which not only ensures rapid treatment during high pollution but also prevents long-term high-load operation loss of the equipment, balancing the treatment effect and equipment economy.

[0065] Embodiment 2

[0066] According to Figure 1 、 2 、3, 4, 5, 6, the usage method of the flying floc sedimentation device for preventing air pollution in the textile workshop is proposed in this embodiment, including the following steps:

[0067] Adjust the positions of each moving vehicle 3 so that it is above the textile equipment;

[0068] Drive the moving frame 2 to move along the gantry 1;

[0069] The vacuum cleaner 8 operates, provides suction to the absorption tube 4 through the stretchable hose 7, and absorbs flying flocs into the collection hopper 6 through the absorption tube 4;

[0070] When a process returns to the origin, the discharge pipe 9 and the atomization pipe 10 are connected;

[0072] Spray sedimentation is carried out in the atomization pipe 10, and then it falls into the compression bin 11 to press the humidified and sedimented flying flocs into blocks, thereby preventing pollution.

[0073] This invention combines flexible coverage with a closed-loop pollution treatment system. The sliding cooperation of the gantry frame 1 and the mobile frame 2 achieves large-scale coverage of the workshop. Multiple independently adjustable moving carts 3 can precisely correspond to the areas above different textile equipment. The absorption pipe 4, collection hopper 6, conveying pipe 5, atomizing pipe 10, and compression chamber 11 are sequentially connected, forming a complete process of fluff absorption, centralized conveying, spraying sedimentation, and briquetting disposal. This avoids secondary diffusion of fluff during collection and reduces the difficulty of subsequent cleaning through briquetting, effectively blocking the transmission path of fluff pollution from a physical perspective. Furthermore, it achieves precise and energy-efficient pollution control. High-precision sensors collect fluff density in real time, triggering operational interval adjustments based on a preset threshold ρo. Combined with the workshop space volume and the k-value calibrated by the number of equipment, the interval adjustment closely matches the actual pollution generation patterns. During low pollution, the initial interval N is maintained to avoid wasted energy; during high pollution, the interval is shortened to increase the treatment frequency. This ensures energy optimization when pollution levels are within limits and timely response to rising pollution trends, preventing pollution accumulation. Meanwhile, this invention further enhances the system's ability to cope with continuous pollution. By eliminating accidental interference through the average density ρ_avg of M consecutive times, the persistence of pollution can be accurately determined. Combined with the m value calibrated by the suction volume of the absorption pipe 4, the speed adaptability is improved. With the temporary increase of the k value and the shortening of the secondary interval, a dual enhancement mechanism of "frequency + efficiency" is formed. At the same time, the parameter recovery logic after pollution mitigation is set up to ensure rapid processing during high pollution and prevent equipment from being worn out by long-term high-load operation, thus balancing the treatment effect and the economic efficiency of the equipment.
