Description

Technical Field

[0001] This invention relates to the field of textile production equipment technology, and in particular to a dust removal device for textile production. Background Technology

[0002] In the textile production process, processes such as spinning, carding, and weaving generate a large amount of dust and fiber lint. If these pollutants are not treated in time, they will not only adhere to the surface of textile fabrics, leading to more product defects and a decline in quality, but will also permeate the workshop air. Long-term inhalation by operators can easily cause respiratory diseases. At the same time, dust accumulation also poses a safety hazard of static electricity ignition, seriously affecting production safety and the working environment.

[0003] Existing dust removal equipment in textile workshops mainly uses simple filter-type dust removal devices, which rely on fans to draw in dust-laden airflow and trap dust through filters. However, when dealing with high concentrations of dust, the filters are prone to clogging quickly, requiring frequent manual disassembly and cleaning, which not only interrupts the production process but also increases labor maintenance costs. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a dust removal device for textile production, which solves the problems of easy clogging of filters in existing dust removal devices, requiring frequent manual disassembly and cleaning, leading to interruptions in the production process and increased manual maintenance costs.

[0005] To achieve the above objectives, the present invention provides a dust removal device for textile production, which adopts the following technical solution: A dust removal device for textile production includes a dust removal chamber and a controller. One side of the dust removal chamber is connected to an air inlet pipe, and the other side is connected to an air outlet pipe. Inside the dust removal chamber, along the airflow direction, are sequentially arranged a pre-dust settling chamber and a filter chamber. The pre-dust settling chamber is equipped with a water spray assembly. The controller controls the water spray assembly to spray water onto the dust-laden airflow within the pre-dust settling chamber. The filter chamber is equipped with a filter screen and a cleaning assembly. The cleaning assembly is slidably disposed within the filter chamber via a lifting device. The controller controls the cleaning assembly to clean the filter screen.

[0006] Furthermore, the pre-dust settling chamber and the filter chamber are separated by a guide plate, and the guide plate has multiple guide holes arranged in a matrix.

[0007] Furthermore, the water spray assembly includes a water storage tank and a main water supply pipeline. The water storage tank is fixed to the top of the dust removal box. One end of the main water supply pipeline is connected to the water storage tank, and the other end extends into the interior of the pre-dust reduction chamber. The main water supply pipeline is equipped with a water pump and a flow regulating valve. The flow regulating valve is electrically connected to the controller. Several water supply branch pipelines are also connected to the main water supply pipeline. Multiple atomizing nozzles are provided on the main water supply pipeline and the water supply branch pipelines.

[0008] Furthermore, the cleaning assembly includes a water spray frame, on which a water spray pipe is fixed. The water spray pipe is connected to the water storage tank via a connecting hose, and the water spray pipe is equipped with multiple high-pressure nozzles.

[0009] Furthermore, the lifting device includes a drive motor fixedly installed on the top of the dust collector, a lead screw fixedly connected to the output shaft of the drive motor, the lead screw being vertically installed and extending into the dust collector, a slider being threadedly connected to the lead screw, and the slider being fixedly connected to one side of the water spray frame.

[0010] Furthermore, the dust collector is also equipped with two vertical guide rails located on both sides of the lead screw. Guide blocks are slidably fitted on the outer side of the vertical guide rails, and the guide blocks are fixedly connected to the water spray frame.

[0011] Furthermore, it also includes an image processing component, which is installed in the pre-dust settling chamber of the dust removal box and is used to detect the dust concentration in the pre-dust settling chamber. The image processing component includes an industrial camera and an image processor. The industrial camera is fixed on the inner wall of the pre-dust settling chamber, and its lens faces the inside of the pre-dust settling chamber. The image processor is electrically connected to the industrial camera and the controller.

[0012] Furthermore, the image analysis step of the image processing component includes: S1. Capture color images of the pre-dust removal chamber using an industrial camera and transmit them to an image processor; S2. The image processor sequentially performs grayscale conversion, noise suppression, contrast enhancement, and background subtraction to eliminate interference and enhance the characteristics of dust particles. S3. Obtain the total number of effective dust particles N by using the Otsu method threshold segmentation, morphological processing, Canny edge detection, and particle count. S4. Calculate the effective analysis area pixel area S, obtain the distribution density according to ρ=N / S, and convert it into real-time dust concentration C through the preset calibration model C=k×ρ+b, where k is the proportional coefficient and b is the correction coefficient. S5. The calculated dust concentration C is transmitted to the controller, which controls the opening and closing of the flow regulating valve according to the dust concentration.

[0013] Furthermore, the adjustment rules for the flow regulating valve are as follows: it is opened when the dust concentration is ≥50mg / m³, closed when the dust concentration is <50mg / m³, the flow rate of the flow regulating valve is set to 10-15L / min when the dust concentration is 50-100mg / m³, and the flow rate of the flow regulating valve is set to 15-20L / min when the dust concentration is >100mg / m³.

[0014] Furthermore, pressure sensors are provided on both sides of the filter screen. The preset pressure difference threshold between the two pressure sensors is 500Pa. When the pressure difference between the two sides of the filter screen exceeds 500Pa, the controller starts the cleaning component to clean the filter screen.

[0015] The beneficial effects of this invention are: This invention relates to a dust removal device for textile production. Two pressure sensors monitor the pressure difference across a filter in real time. When the pressure difference exceeds a certain threshold, the controller automatically activates the cleaning component, eliminating the need for manual disassembly and cleaning. This prevents production interruptions due to filter clogging and reduces maintenance costs. A water spray component sprays atomized water mist onto the dust-laden airflow, causing most dust particles to combine with the mist and settle, reducing the filtration load on subsequent filters. The pre-dust-settled airflow then undergoes deep filtration through the filter, trapping fine dust particles. This dual purification process results in a significantly higher dust removal rate, far superior to traditional single-dust removal devices. An image processing component accurately detects dust concentration, enabling on-demand water spraying and conserving water resources. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1 and Figure 2 The dust removal device for textile production of the present invention is shown, which includes a dust removal box 1 and a controller (not shown in the figure). One side of the dust removal box 1 is connected to an air inlet pipe 11, and the other side is connected to an air outlet pipe (not shown in the figure). Inside the dust removal box 1, a pre-dust settling chamber 12 and a filter chamber 13 are arranged sequentially along the airflow direction. A water spraying assembly 2 is provided in the pre-dust settling chamber 12. The controller is used to control the water spraying assembly 2 to spray water onto the dust-laden airflow in the pre-dust settling chamber 12. A filter screen 3 and a cleaning assembly 4 are provided in the filter chamber 13. The cleaning assembly 4 is slidably arranged in the filter chamber 13 through a lifting device 5. The controller controls the cleaning assembly 4 to clean the filter screen 3.

[0020] The dust collector housing 1 is a sealed hollow structure with an air inlet pipe 11 on one side and an air outlet pipe on the other side. Inside the dust collector housing 1, along the airflow direction, there are a pre-dust settling chamber 12 and a filter chamber 13, separated by a guide plate 14. The guide plate 14 has multiple guide holes arranged in a matrix. These guide holes on the guide plate 14 are used to guide the pre-dust-set airflow smoothly into the filter chamber 13.

[0021] One side of the dust collector 1 is connected to an air inlet pipe 11, and the other side is connected to an air outlet pipe. The air inlet pipe 11 is used to draw dust-laden airflow generated during textile production into the pre-dust settling chamber 12 of the dust collector 1. One end of the air inlet pipe 11 is sealed to the dust-generating part of the textile production equipment, and the other end is connected to the air inlet of the dust collector 1. An air inlet fan 15 is also installed on the air inlet pipe 11 to provide power for drawing in the dust-laden airflow. Preferably, an airflow distribution plate (not shown in the figure) can also be installed inside the air inlet in the pre-dust settling chamber 12. This plate has several evenly distributed holes to ensure that the dust-laden airflow is evenly diffused into the pre-dust settling chamber 12, preventing excessively high local airflow velocity from affecting the water spray dust suppression effect.

[0022] A water spray assembly 2 is installed inside the pre-dust settling chamber 12. A controller is used to control the water spray assembly 2 to spray water onto the dust-laden airflow inside the pre-dust settling chamber 12. The water spray assembly 2 includes a water storage tank 21 and a main water supply pipeline 22. The water storage tank 21 is fixed to the top of the dust collector 1. One end of the main water supply pipeline 22 is connected to the water storage tank 21, and the other end extends into the interior of the pre-dust settling chamber 12. Several branch water supply pipelines 23 are also connected to the main water supply pipeline 22. Multiple atomizing nozzles 24 are installed on the main water supply pipeline 22 and the branch water supply pipelines 23. Preferably, the water spraying direction of the atomizing nozzles 24 forms an angle of 45° to 60° with the flow direction of the dust-laden airflow to ensure sufficient contact between the water mist and the airflow. A water pump and a flow regulating valve (not shown in the figure) are installed on the main water supply pipeline 22. The flow regulating valve is electrically connected to the controller and is used to regulate the water spraying flow rate of the atomizing nozzles 24.

[0023] The filter chamber 13 contains a filter screen 3 and a cleaning component 4. The filter screen 3 is shown in the figure for illustrative purposes only. The filter screen 3 has multiple filter holes arranged in a matrix. To ensure effective trapping of fine dust, the filter screen 3 preferably has a filtration accuracy of 0.3-1mm, but this is not a limitation; the filtration accuracy can be designed according to actual needs. A dust collection trough (not shown in the figure) can also be installed at the bottom of the dust collector 1. This trough collects dust that falls during the filtration process of the filter screen 3 and wastewater dripping from the water spray component 2. The bottom of the dust collection trough is inclined to allow dust and wastewater to slide freely to its lowest point. A drain valve is located at the bottom of the dust collection trough for periodic cleaning of the mixture of wastewater and dust.

[0024] The invention also includes an image processing component (not shown in the figure), which is disposed within the pre-dust settling chamber 12 of the dust collection box 1 and is used to detect the dust concentration within the pre-dust settling chamber 12. The image processing component includes an industrial camera and an image processor. The industrial camera is fixed to the inner wall of the pre-dust settling chamber 12, with its lens facing inwards. The image processor is electrically connected to the industrial camera and the controller. A supplementary light is also installed beside the industrial camera to provide a stable light source and ensure image clarity. The image processor is electrically connected to the industrial camera and is used to analyze and process the airflow images captured by the industrial camera. By identifying the number and distribution density of dust particles in the image, the real-time dust concentration within the pre-dust settling chamber 12 is calculated, and the concentration data is transmitted to the controller. A dustproof glass cover is provided on the outer side of the industrial camera lens to protect the lens from dust and ensure its shooting accuracy.

[0025] Specifically, the image analysis steps of the image processing component include: S1. A color image of the pre-dust settling chamber 12 is captured by an industrial camera and transmitted to the image processor. The image processor establishes a stable electrical connection with the industrial camera via standard interfaces such as GigE Vision and USB3 Vision, completing communication protocol adaptation and ensuring a transmission bandwidth of ≥1Gbps. The industrial camera captures images at a frame rate of ≥30fps, and the image processor simultaneously receives raw RAW or BMP images with a resolution of ≥1920×1080 pixels, which are then transmitted to the image processor.

[0026] S2. The image processor sequentially performs grayscale conversion, noise suppression, contrast enhancement, and background subtraction to eliminate interference and enhance dust particle characteristics. Specifically, in this embodiment, a weighted average method is used to convert the color image into a single-channel grayscale image; a 3×3 or 5×5 windowed mid-range filter is used to remove salt-and-pepper noise, combined with a Gaussian filter with σ=0.8~1.2 to smooth the background; histogram equalization or adaptive contrast stretching algorithm is used to expand the grayscale difference between particles and the background; based on a dust-free baseline image, the foreground region is extracted using the frame difference method or Gaussian mixture model to remove fixed background interference.

[0027] S3. Obtain the total number of effective dust particles N by using Otsu's threshold segmentation, morphological processing, Canny edge detection, and particle count. In this embodiment, step S3 uses Otsu's method to automatically determine the grayscale threshold and segment the image into a binary image; performs dilation-erosion operation on the binary image to fill holes, connect broken edges, and remove noise with an area < 5 pixels; extracts particle contours and obtains geometric parameters by Canny edge detection; excludes adherent particles with an overlap of more than 30%, and counts the total number of effective particles N.

[0028] S4. Calculate the effective analysis area pixel area S, obtain the distribution density using ρ=N / S, and convert it to real-time dust concentration C using the preset calibration model C=k×ρ+b, where k is the proportionality coefficient and b is the correction coefficient. Distribution density calculation and dust concentration conversion: Define the effective analysis area of ​​the airflow and calculate the total pixel area S; calculate the particle distribution density ρ using ρ=N / S; call the preset calibration model C=k×ρ+b to convert ρ to real-time dust concentration C (unit: mg / m³), where k is the proportionality coefficient and b is the correction coefficient, calibrated based on different dust types and airflow velocities; compare the current concentration with the historical data fluctuation range, and if it exceeds ±10%, repeat the analysis steps.

[0029] S5. The calculated dust concentration C is transmitted to the controller, which controls the opening and closing of the flow regulating valve based on the dust concentration. The adjustment rules for the flow regulating valve are as follows: it is open when the dust concentration is ≥50mg / m³, closed when the dust concentration is <50mg / m³, the flow rate of the flow regulating valve is set to 10-15L / min when the dust concentration is 50-100mg / m³, and the flow rate of the flow regulating valve is set to 15-20L / min when the dust concentration is >100mg / m³.

[0030] The cleaning assembly 4 is used to clean the filter screen 3. The cleaning assembly 4 includes a water spray frame 41, on which a water spray pipe 42 is fixed. The water spray pipe 42 is connected to the water storage tank 21 via a connecting hose. The water spray pipe 42 is equipped with multiple high-pressure nozzles 43, and the water spray direction of the multiple high-pressure nozzles 43 is towards the surface of the filter screen 3. A high-pressure water pump (not shown in the figure) is also installed on the water spray pipe 42, which is used to provide high-pressure water flow to the high-pressure nozzles 43.

[0031] The cleaning component 4 is slidably mounted inside the filter chamber 13 via a lifting device 5, which is located inside the dust collection box 1. The lifting device 5 includes a drive motor 51 fixedly mounted on the top of the dust collection box 1, and a lead screw 53 is fixedly connected to the output shaft of the drive motor 51. In this embodiment, a support frame 52 is fixed inside the dust collection box 1, the lead screw 53 is vertically mounted and rotatably connected to the support frame 52, and the lead screw 53 extends into the dust collection box 1 through it. A slider 54 is threaded onto the lead screw 53, and the slider 54 is fixedly connected to one side of the water spray frame 41 via a connecting frame 55. Two vertical guide rails 56 are also provided inside the dust collection box 1. The two vertical guide rails 56 are fixedly mounted on the support frame 52 and located on both sides of the lead screw 53. Guide blocks 57 are slidably fitted on the outer side of the vertical guide rails 56, and the guide blocks 57 are fixedly connected to the water spray frame 41 via the connecting frame 55. The connecting frame 55 has an E-shaped structure. One side of the middle section of the connecting frame 55 is fixedly connected to the middle section of the spray frame 41, and the other side is fixedly connected to the slider 54. Both ends of the connecting frame 55 are fixedly connected to the corresponding guide blocks 57. A partition plate 58 is vertically arranged between the spray frame 41 and the lead screw 53. An elongated hole is provided on the partition plate 58. The middle section of the connecting frame 55 passes through the elongated hole and extends inward to be fixedly connected to the middle section of the spray frame 41. Two accordion sealing strips are installed on the elongated hole: a first accordion sealing strip 59 and a second accordion sealing strip 50. One end of the first accordion sealing strip 59 is fixedly connected to the top of the elongated hole, and the other end is fixedly connected to the top of the middle section of the connecting frame 55. One end of the second accordion sealing strip 50 is fixedly connected to the bottom of the elongated hole, and the other end is fixedly connected to the bottom of the middle section of the connecting frame 55. When the connecting frame 55 slides up and down within the elongated hole, the two accordion sealing strips provide a good sealing effect. Start the drive motor 51. The output shaft of the drive motor 51 rotates, which drives the lead screw 53 to rotate. The rotation of the lead screw 53 drives the slider 54 to move up and down in the vertical direction. The up and down movement of the slider 54 drives the water spray frame 41 and the high-pressure nozzle 43 to move up and down, thereby cleaning the filter screen 3 in a comprehensive manner.

[0032] Pressure sensors (not shown in the figure) are respectively installed on both sides of the filter screen 3, one on the air inlet side and the other on the air outlet side, to detect the pressure difference between the two sides in real time. The invention also includes a data transmission module electrically connected to the pressure sensors, which transmits the pressure difference data between the two sides of the filter screen 3 to the controller. The preset pressure difference threshold for the two pressure sensors is 500 Pa. When the pressure difference between the two sides of the filter screen 3 exceeds 500 Pa, the controller activates the cleaning component 4 to clean the filter screen 3.

[0033] The working process of the dust removal device for textile production of the present invention is as follows: The controller starts the air intake fan 15, and the dust-laden airflow generated during the textile production process is drawn into the pre-dust settling chamber 12 of the dust removal box 1 through the air intake pipe 11. An industrial camera captures an image of the airflow in the pre-dust settling chamber 12 and transmits it to the image processor. The image processor analyzes and processes the received color image and calculates the real-time dust concentration C in the pre-dust settling chamber 12 and transmits it to the controller. The controller controls the flow regulating valve according to the dust concentration C: when the dust concentration C ≥ 50 mg / m³, the water pump is turned on; when the dust concentration C < 50 mg / m³, it is turned off; when the dust concentration C is 50-100 mg / m³, the flow rate is set to 10-15 L / min; when the dust concentration C > 100 mg / m³, the flow rate is set to 15-20 L / min. Water in the water storage tank 21 is transported to the atomizing nozzle 24 via the main water supply pipe 22 and branch pipes. The atomizing nozzle 24 sprays out a mist of water, which comes into full contact with the dust-laden airflow to achieve pre-dust reduction. The pre-dust-reduced airflow smoothly enters the filter chamber 13 through the matrix guide holes of the guide plate 14, and further traps fine dust through the matrix filter holes of the filter screen 3. The purified airflow is discharged through the outlet pipe. During this process, the pressure sensors on the air inlet and outlet sides of the filter screen 3 detect the pressure difference in real time and send it to the controller via the data transmission module. When the pressure difference detected by the pressure sensor exceeds the preset threshold of 500Pa, the controller activates the cleaning component 4, i.e., the drive motor 51. The output shaft of the drive motor 51 rotates, driving the lead screw 53 to rotate. The rotation of the lead screw 53 causes the slider 54 to move vertically along the axis of the lead screw 53. At the same time, the guide block 57 slides along the vertical guide rails 56 on both sides, driving the water spray frame 41 to move up and down through the E-shaped connecting frame 55. The high-pressure water pump starts, and the water in the water storage tank 21 is transported to the high-pressure nozzle 43 through the connecting hose and the water spray pipe 42. The high-pressure nozzle 43 sprays high-pressure water onto the surface of the filter screen 3, and moves up and down with the water spray frame 41 to achieve full surface cleaning of the filter screen 3. The wastewater generated by the pre-dust reduction and the dust that falls off the filter screen 3 after filtration and cleaning fall into the bottom dust collection tank. Because the bottom of the dust collection tank is inclined, the mixture automatically slides to the lower end and is periodically discharged through the drain valve for cleaning.

[0034] While the present invention discloses preferred embodiments to achieve the above objectives, these are not intended to limit the structural features of the invention. Anyone skilled in the art should know that any easily conceived variations or modifications are possible within the technical spirit of the invention and are covered by the claims of the present invention.
