Description

Technical Field

[0001] This invention relates to a textile dust collection device for textile machines, and more particularly to a textile dust collection device for textile machines, belonging to the technical field of textile industry. Background Technology

[0002] When textile machines are in operation, textile dust must be collected because it mainly consists of fiber debris, short fibers, dye particles, and chemical auxiliaries. If it remains suspended in the air for a long time, it will seriously harm the respiratory system of workers and cause occupational diseases such as pneumoconiosis, asthma, and even cancer. Collecting dust is a core measure to protect occupational health. Secondly, high concentrations of textile dust pose an explosion risk and may cause fires if it accumulates on equipment or circuits. Collection can significantly reduce safety hazards.

[0003] Most textile dust collection equipment on the market currently adopts an open design, which causes a large amount of textile dust to spread and float in the working environment. The open structure not only increases the amount of dust that escapes, but also significantly reduces the collection efficiency. In addition, open equipment is easily affected by airflow during operation, resulting in incomplete dust collection and even affecting subsequent dust recovery.

[0004] Therefore, it is urgent to improve the textile dust collection equipment for textile machines to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a textile dust collection device for textile machines, which can cover the textile machine with a cleaning hood to prevent textile dust from floating in the working environment, and then collect the textile dust using air ducts.

[0006] To achieve the above objectives, the main technical solution adopted by the present invention includes: a cleaning cover and a textile machine body disposed inside the cleaning cover. An air duct is fixedly disposed on the outside of the cleaning cover. One end of the air duct is connected to the upper part of the inside of the cleaning cover, and the other end of the air duct is connected to the lower part of the inside of the cleaning cover through a bottom ventilation pipe. A filter box is fixedly installed at the connection between the air duct and the bottom ventilation duct. The upper and lower sides of the filter box are connected to the air duct and the bottom ventilation duct. At least three first filter screens for filtering textile dust are slidably installed inside the filter box, and a certain gap is left between each first filter screen. Each of the first filter screens is provided with a scraper frame on its lower side, which is slidably connected to the inner wall of the filter box. The scraper frame is used for cleaning the surface of the first filter screen. The upper and lower sides of the two scraper frames abut against the upper and lower surfaces of the two first filter screens. An atomizing box is fixedly installed on one side of the filter box. Several atomizing nozzles are fixedly installed side by side inside the atomizing box. Each atomizing nozzle extends into the atomizing box and is located above the scraper frame. A collection box for collecting textile dust is fixedly installed at the lower end of the atomizing box.

[0007] Preferably, the filter box has a number of mounting seats that are the same as the number of the first filter screens fixedly arranged on the side away from the opening, and each of the first filter screens has a plug-in seat fixedly arranged on one side to be inserted into the mounting seat. The connector is provided with several locking blocks, and the mounting base is provided with several slots for the locking blocks to engage.

[0008] Preferably, the inner wall of the filter box is provided with slide rails on both opposite sides, which are slidably connected to the scraper frame. A rubber sealing strip is fixedly provided on one side of the slide rail, and a through groove extending to the outside of the filter box is provided on both the slide rail and the rubber sealing strip.

[0009] Preferably, each scraper frame has a toggle handle fixedly connected to both sides by a connecting rod, the connecting rod is slidably connected to the through groove, and each toggle handle is located on opposite sides of the filter box for sliding toggle the scraper frame.

[0010] Preferably, each of the atomizing nozzles is connected to a water storage tank via a water pipe. The water storage tank is used for liquid storage and is fixedly connected to the side of the atomizing box away from the filter box. The atomizing box is connected to the collection box, and a drain pipe is fixedly installed on one side of the collection box for discharging wastewater.

[0011] Preferably, a metal perforated plate is fixedly installed at one end of the bottom ventilation pipe, and the metal perforated plate is fixedly connected to a collection basin fixedly installed at the bottom of the cleaning cover; The shape of the collection basin and the metal perforated plate is the same as the shape of the bottom of the textile machine body.

[0012] Preferably, a fixed frame is fixedly installed in the middle of the air duct, and two fans are fixedly installed inside the fixed frame. The two fans are arranged vertically side by side, and fan blades are rotatably connected to the inside of each fan through a bracket.

[0013] Preferably, the connection between the air duct and the upper half of the cleaning hood is the air outlet, and the connection between the air duct and the lower half of the cleaning hood is the air inlet for collecting textile dust. The air volume at the air outlet is less than that at the air inlet.

[0014] Preferably, a second filter screen is fixedly installed at the air outlet of the air duct by bolts, and the second filter screen is used for the final filtration of textile dust.

[0015] Preferably, a rotating base plate is hinged to the lower half of one side of the cleaning cover, and an acrylic plate is rotatably connected to the middle of one side of the cleaning cover via a rotating rod. Both the rotating base plate and the acrylic plate are used to open or close the opening of the cleaning cover.

[0016] The present invention has at least the following beneficial effects: 1. The setup of two fans creates negative pressure inside the duct, allowing the duct to absorb and store textile dust that settles downwards inside the cleaning hood via the bottom ventilation pipe. During this process, the other end of the duct supplies airflow into the cleaning hood. Due to the slight bend at the connection between the duct and the upper part of the cleaning hood, the strong air pressure is reduced, resulting in less air output than intake. Simultaneously, the cleaning hood seals the textile machine, preventing dust from floating directly to the outside, thereby increasing the textile dust recovery rate.

[0017] 2. When textile dust is absorbed, it will first come into contact with the first filter screen. Multi-layer filtration can separate textile dust from airflow. When the staff needs to collect textile dust, they can manually move the scraper frame on the surface of the first filter screen. In this way, the textile dust can gradually separate from the first filter screen and move towards the atomization box.

[0018] 3. In order to filter textile dust of different degrees, the three first filter screens can be divided into coarse filter, fine filter and fine filter from bottom to top. The filtration effect of the three is not the same. At the same time, the first filter screens that come into contact with the upper and lower sides of the two scraper frames are coarse filter and fine filter respectively. The purpose is to clean the upper side of the two screens. Textile dust will eventually be blocked by the fine filter, so there is no need to excessively clean the upper side of the fine filter.

[0019] 4. When the textile dust cleaned by the scraper moves into the atomizing box, it first passes through the water mist area created by multiple atomizing nozzles arranged side by side. When the textile dust comes into contact with the water mist, its weight increases, and it will then settle downwards into the collection box for storage. The wastewater is then discharged through the drain pipe. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-9As shown in the figure, this embodiment provides a textile dust collection device for textile machines, including a cleaning hood 1 and a textile machine body 3 disposed inside the cleaning hood 1. A duct 2 is fixedly installed on the outside of the cleaning hood 1. One end of the duct 2 is connected to the upper part of the inside of the cleaning hood 1, and the other end of the duct 2 is connected to the lower part of the inside of the cleaning hood 1 through a bottom ventilation pipe 9. A fixing frame 202 is fixedly installed in the middle of the duct 2. Two fans 203 are fixedly installed inside the fixing frame 202. The two fans 203 are arranged vertically side by side, and the inside of each fan 203 is rotatably connected by a bracket. With fan blades 204 and two fans 203 connected, the air duct 2 can generate negative pressure inside the air duct 2. Thus, the air duct 2 can absorb and store the textile dust that settles downward inside the cleaning hood 1 using the bottom ventilation pipe 9. During this process, the other end of the air duct 2 can supply airflow into the cleaning hood 1. Since the connection between the air duct 2 and the upper part of the cleaning hood 1 has a slight corner arc, the strong air pressure will be weakened here, so as to achieve the effect of the exhaust air being less than the intake air. The two fans 203 can be stably installed inside the air duct 2 by the fixing frame 202 and are not affected by the negative pressure.

[0024] A filter box 5 is fixedly installed at the connection between the air duct 2 and the bottom ventilation duct 9. The upper and lower sides of the filter box 5 are connected to the air duct 2 and the bottom ventilation duct 9. At least three first filter screens 10 for filtering textile dust are slidably installed inside the filter box 5, and a certain gap is left between each first filter screen 10. Each first filter screen 10 has a scraper frame 13 slidably connected to the inner wall of the filter box 5 on its lower side. The scraper frame 13 is used to clean the surface of the first filter screen 10. The upper and lower sides of two scraper frames 13 are abutted against the upper and lower sides of two of the first filter screens 10. When textile dust is absorbed, it will first come into contact with the first filter screen 10. Multi-layer filtration can separate textile dust from airflow. When the staff needs to collect textile dust, the scraper frame 13 can be moved manually on the surface of the first filter screen 10. In this way, the textile dust can gradually separate from the first filter screen 10 and move towards the atomizing box 6. This process is used when the equipment is stopped. In order to filter textile dust of different levels, the three first filter plates 10 can be divided into coarse filter, fine filter and fine filter from bottom to top. The filtration effect of the three is not the same. At the same time, the first filter plates 10 that are in contact with the upper and lower sides of the two scraper frames 13 are coarse filter and fine filter respectively. The purpose is to clean the upper side of the two. Textile dust will eventually be blocked by the fine filter, so there is no need to clean the upper side of the fine filter excessively. However, after long-term use, the upper side of the fine filter still needs to be cleaned by disassembly, or the three first filter plates 10 need to be replaced.

[0025] The inner wall of the filter box 5 has slide rails 503 on both sides that are slidably connected to the scraper frame 13. A rubber sealing strip 504 is fixedly installed on one side of the slide rail 503. The slide rail 503 and the rubber sealing strip 504 are both provided with through grooves 505 extending to the outside of the filter box 5. Each scraper frame 13 has a lever handle 14 fixedly connected to both sides by a connecting rod. The connecting rod and the through groove 505 are slidably connected. Each lever handle 14 is located on both sides of the filter box 5 and is used to slide the scraper frame 13. Multiple first filter screens 10 are slidably installed inside the filter box 5, which facilitates cleaning after disassembly of the equipment and replacement of the first filter screens 10. At the same time, each scraper frame 13 is fixedly connected to the lever handle 14 by a connecting rod, which allows the operator to easily pull the scraper frame 13 to slide inside the filter box 5 by lever handle 14, thereby achieving the above-mentioned cleaning effect on the surface of the first filter screen 10. At the same time, the scraper frame 13 can also provide support for the first filter screen 10. In order to improve the seal between the filter box 5 and the connecting rod, the rubber sealing strip 504 provided on one side of the slide rail 503 can utilize its own contraction characteristics to automatically contract and close the through groove 505 when the lever handle 14 is not used, thereby reducing the outward leakage of airflow.

[0026] Atomizing box 6 is fixedly installed on one side of filter box 5. Several atomizing nozzles 603 are fixedly installed side by side inside atomizing box 6. Each atomizing nozzle 603 extends into the atomizing box 6 and is located above scraper frame 13, so as not to obstruct the movement of scraper frame 13. A collection box 7 for collecting textile dust is fixedly installed at the lower end of atomizing box 6. Atomizing box 6 and collection box 7 are connected. A drain pipe 8 is fixedly installed on one side of collection box 7 for discharging wastewater. When textile dust cleaned by scraper frame 13 moves into atomizing box 6, it will first pass through the water mist area created by multiple atomizing nozzles 603 arranged side by side. When textile dust comes into contact with water mist, its weight will increase, and it will then settle downward into the interior of collection box 7 for storage. Then, the wastewater will be discharged in a concentrated manner through drain pipe 8. In this way, the cleaning of textile dust can be completed. Each atomizing nozzle 603 is connected to a water storage tank 601 via a water pipe 602. The water storage tank 601 is used for liquid storage and is fixedly connected to the side of the atomizing box 6 away from the filter box 5. The arrangement of the water storage tank 601 and the water pipe 602 can provide liquid supply to the atomizing nozzle 603, enabling the atomizing nozzle 603 to create a water mist area at the opening of the atomizing box 6.

[0027] Furthermore, such as Figure 6As shown; inside the filter box 5, on the side away from the opening, there are fixed mounting bases 501 in the same number as the first filter screens 10. Each first filter screen 10 has a fixed insertion base 11 on one side that is inserted into the mounting base 501. The first filter screen 10 can be inserted into the mounting base 501 fixed inside the filter box 5 through the insertion base 11, thereby limiting the position and height of multiple first filter screens 10 so that multiple first filter screens 10 can play their corresponding roles. The connector 11 is fixedly provided with several locking blocks 12, and the mounting base 501 is provided with several slots 502 for the locking blocks 12 to engage. In order to securely connect the first filter screen 10 and the filter box 5, when the connector 11 is plugged into the mounting base 501, the locking blocks 12 on the connector 11 can engage with the slots 502, thereby fixing and restricting the connection between the connector 11 and the mounting base 501, and preventing the connector 11 and the mounting base 501 from separating during use.

[0028] Furthermore, such as Figures 1-4 As shown; a metal perforated plate 401 is fixedly installed at one end of the bottom ventilation pipe 9. The metal perforated plate 401 is fixedly connected to the collection basin 4 fixedly installed at the bottom of the cleaning cover 1. The metal perforated plate 401 can filter out larger impurities and prevent larger impurities from being sucked into the air pipe 2 and affecting the filtration of the first filter screen 10. The shape of the collection basin 4 and the metal perforated plate 401 is the same as the bottom shape of the textile machine body 3, which can minimize the cleaning blind spots.

[0029] Furthermore, such as Figure 9 As shown; the connection between the air duct 2 and the upper part of the cleaning hood 1 is the air outlet, and the connection between the air duct 2 and the lower part of the cleaning hood 1 is the air inlet, which is used for collecting textile dust. The air volume at the air outlet is less than that at the air inlet. After the air duct 2 filters and separates the textile dust and airflow through the first filter screen 10, the airflow can continue to provide airflow into the cleaning hood 1 through the air outlet of the air duct 2, which provides assistance for the absorption of textile dust by the air inlet and can effectively prevent textile dust from floating upward. Meanwhile, the air duct 2 uses only one drive device for both air outlet and air inlet, which can significantly reduce environmental noise and requires less energy during use.

[0030] A second filter plate 201 is fixedly installed at the air outlet of the air duct 2 by bolts. The second filter plate 201 is used for the final filtration of textile dust. When the filtered airflow is poured into the cleaning hood 1 through the air outlet of the air duct 2, it will be filtered again by the second filter plate 201, thereby maximizing the filtration and separation of airflow and textile dust. At the same time, the second filter plate 201 can further reduce the airflow velocity, ensuring that the airflow at the air outlet is relatively slow and that the textile dust inside the cleaning hood 1 will not be disturbed due to excessive airflow.

[0031] Furthermore, such as Figures 1-2 As shown; a rotating base plate 101 is hinged to the lower half of one side of the cleaning cover 1, and an acrylic plate 102 is rotatably connected to the middle of one side of the cleaning cover 1 via a rotating rod. Both the rotating base plate 101 and the acrylic plate 102 are used to open or close the opening of the cleaning cover 1. In use, the operator can connect the acrylic plate 102 and the rotating base plate 101 to the body of the cleaning cover 1 so that the air duct 2 can absorb and filter textile dust. At the same time, the connection between the acrylic plate 102 and the rotating base plate 101 and the cleaning cover 1 is a common connection method, which will not be described in detail here.

[0032] like Figures 1-9 As shown in this embodiment, the principle of a textile dust collection device for textile machines is as follows: The air duct 2 can absorb and store the textile dust that settles downward inside the cleaning hood 1 using the bottom ventilation pipe 9. During this process, the other end of the air duct 2 can supply airflow into the cleaning hood 1. Since the connection between the air duct 2 and the upper part of the cleaning hood 1 has a slight corner arc, the strong air pressure will be weakened here, so as to achieve the effect of the outflow being less than the inflow. When the textile dust is absorbed, it will first come into contact with the first filter screen 10. Multi-layer filtration can separate the textile dust from the airflow. When the staff needs to collect the textile dust, the scraper frame 13 can be moved manually on the surface of the first filter screen 10, so that the textile dust can gradually separate from the first filter screen 10 and move towards the atomizing box 6. When the textile dust cleaned by the scraper frame 13 moves into the atomizing box 6, it first passes through the water mist area created by multiple atomizing nozzles 603 arranged side by side. When the textile dust comes into contact with the water mist, its weight increases, and it then settles downwards into the collection box 7 for storage. Then, the wastewater is discharged through the drain pipe 8, thus completing the cleaning of the textile dust.
