Description

Technical Field

[0001] This utility model relates to the field of textile workshop equipment technology. Background Technology

[0002] In the core of cotton textile production—the spinning and weaving workshops—dust control is a crucial and ongoing task. This environment naturally has a high concentration of dust, primarily originating from the breakage and shedding of cotton fibers during processing due to stretching, combing, and friction, forming visible fly filaments and less noticeable short fibers. This airborne dust poses significant risks to production itself. For example, fly filaments adhering to or entangled on rollers, spindles, and loom components lead to increased equipment wear, higher breakage rates, and defects on yarn and fabric surfaces, directly impacting product quality and production efficiency. More seriously, it poses a health threat to operators. Long-term inhalation of high concentrations of cotton dust can cause respiratory irritation, coughing, chest tightness, and even serious occupational diseases—cotton dust sickness or other respiratory illnesses.

[0003] Therefore, systematic and effective dust control measures are the cornerstone of ensuring safe production in the workshop and the occupational health of employees. Modern cotton textile mills generally adopt comprehensive dust removal solutions: key dust-generating points such as cotton cleaning, carding, combing, and winding are closed or semi-closed; in terms of air purification, they rely on powerful central or regional ventilation and dust removal systems such as cartridge dust collectors, bag dust collectors, and electrostatic precipitators to continuously draw in dust-laden air, and after high-efficiency filtration, clean air is discharged or some fibers are recovered.

[0004] However, existing dust collectors often have a low level of intelligence, and dust bags are prone to accumulation, reducing filtration efficiency. At the same time, most of the dust comes from short fibers, which have reuse value. Traditional dust collectors often have large dust bags that are not cleaned for a long time, and the accumulation of short fibers can easily breed microorganisms, leading to a decrease in utilization value. Utility Model Content

[0005] The purpose of this utility model is to provide a dust filtration device for textile workshops in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A dust filtration device for a textile workshop includes a frame with a filter cartridge mounted on it. The air inlet of the filter cartridge leads into the interior of the textile workshop. The filter cartridge contains a filter bag and a compressed air backwash valve. Several dust collection bags are located at the bottom of the filter cartridge. A dust distribution mechanism is provided between the dust collection bags and the filter cartridge, including a solenoid valve located at the bottom of the filter cartridge. The output end of the solenoid valve has an annular tubular distribution chamber. An inlet pipe is provided between the distribution chamber and the dust collection bags. An electric distribution valve is located inside the inlet pipe. The distribution chamber is detachably connected to the output end of the solenoid valve. A movable weighing component is located at the bottom of the dust collection bags on the frame. A drying component is located inside the dust collection bags. With the above scheme, when the compressed air backflushing valve inside the filter cartridge is activated for dust removal, the detached dust falls into the bottom solenoid valve under gravity. After the solenoid valve opens, the dust first enters the annular distribution chamber, which guides the dust to diffuse evenly. Subsequently, the electric distribution valve, according to instructions, diverts the dust through the inlet pipe to different dust collection bags. This design achieves continuous dust removal and dynamic dust diversion. A moving weighing component weighs the dust collection bags to determine the quality of the collected lint, and a drying component dries the lint to prevent fiber clumping, facilitating subsequent reuse. Furthermore, the distribution chamber can be disassembled when the solenoid valve is closed, allowing the chamber and the full dust collection bags to be moved via the moving weighing component, facilitating the replacement of multiple dust collection bags at once. This device avoids the production capacity loss caused by traditional downtime dust removal, and the multi-bag rotation mechanism significantly extends the single maintenance cycle, enabling dust bag replacement without shutting down the system.

[0007] Furthermore, the mobile weighing assembly includes a platform located at the bottom of the dust collection bag, and the platform has a storage tank at the bottom of each dust collection bag. A weighing sensor is installed in the storage tank. A central controller is also provided, and the electric distribution valve, the solenoid valve, and the weighing sensor are all electrically connected to the central controller. The above scheme sets up a storage tank to easily support individual dust collection bags. At the same time, the weighing sensor on the platform monitors the weight of each dust collection bag in real time, and the data is uploaded to the central controller. When the weight of a dust collection bag approaches the threshold, the controller automatically adjusts the flow direction of the electric distribution valve to switch the dust to a low-load dust collection bag. This not only prevents the dust collection bag from being overloaded and damaged, but also maximizes the utilization of the container volume and reduces the frequency of manual intervention.

[0008] Furthermore, the platform is equipped with casters at its bottom and a handle on one side. The above solution includes the installation of casters and handles, which facilitates the disassembly of the distribution chamber with the solenoid valve closed when replacing the dust collection bag, allowing the distribution chamber and the fully loaded dust collection bag to be moved via the loading platform.

[0009] Furthermore, the inlet pipe is equipped with a flexible connection, and the dust collection bag is stacked on the weighing sensor. The above solution uses a flexible connection design to compensate for displacement deviations, ensuring a sealed dust conveying process and preventing excessive traction on the dust collection bag during dust collection, thus extending the service life of each component.

[0010] Furthermore, the bottom of the distribution chamber is generally conical, and the inlet pipe is evenly connected to the outer periphery of the bottom of the conical distribution chamber. The above scheme uses a conical bottom structure in the distribution chamber to accelerate the flow of dust into the inlet pipe, thus preventing accumulation.

[0011] Furthermore, the drying assembly includes a drying bladder located on one side of the bottom end of the dust collection bag, and the drying bladder is filled with a desiccant. The above solution allows the detachable drying bladder at the bottom to continuously absorb moisture, ensuring that the dust remains in a low-humidity, loose state for easy recycling.

[0012] Furthermore, the drying bladder and the dust collection bag are connected by Velcro fasteners. Furthermore, the inner wall of the dust collection bag is provided with plastic diaphragms.

[0013] The above solution reduces fiber adhesion through the plastic diaphragm on the inner wall of the dust collection bag, making it easier for subsequent use.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model has a simple structure. When the compressed air backwash valve inside the filter cartridge is activated for dust removal, the detached dust falls into the bottom solenoid valve under gravity. After the solenoid valve opens, the dust first enters the annular distribution chamber, which guides the dust to diffuse evenly. Subsequently, the electric distribution valve distributes the dust through the inlet pipe to different dust collection bags according to the instruction. This design realizes continuous dust removal and dynamic dust diversion. At the same time, a moving weighing component is set to weigh the dust collection bags to determine the quality of the collected lint. A drying component is also set to dry the lint to prevent cotton fibers from clumping, facilitating subsequent reuse. Furthermore, this device can disassemble the distribution chamber when the solenoid valve is closed, and move the distribution chamber and the full dust collection bags together via the moving weighing component. This facilitates the replacement of multiple dust collection bags at once. This device can avoid the production capacity loss caused by traditional downtime dust removal. At the same time, the multi-bag rotation mechanism significantly extends the single maintenance cycle and allows for dust bag replacement without stopping the machine. 2. The conical bottom structure of the distribution chamber accelerates the dust to slide into the inlet pipe and avoids accumulation; at the same time, the plastic diaphragm on the inner wall of the dust collection bag reduces fiber adhesion, and the removable drying bladder at the bottom continuously absorbs moisture. The two work together to ensure that the dust is always in a low-humidity and loose state, which facilitates the reuse of high-value cotton fibers and significantly improves the quality of recycled raw materials.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Example 1 like Figure 1As shown, this embodiment provides a dust filtration device for a textile workshop, including a frame 11. A filter cartridge 12 is mounted on the frame 11. The air inlet of the filter cartridge 12 is connected to the interior of the textile workshop, and air is drawn in by a fan, especially during the cotton unpacking process. A filter bag 13 and a compressed air backflow valve 14 are installed inside the filter cartridge 12. Several dust collection bags 15 are installed at the bottom of the filter cartridge 12. A dust distribution mechanism, including a solenoid valve 16 located at the bottom of the filter cartridge 12, is provided between the dust collection bags 15 and the filter cartridge 12. An annular tubular distribution chamber 17 is provided at the output end of the solenoid valve 16. An inlet pipe 18 is provided between the distribution chamber 17 and the dust collection bag 15. An electric distribution valve 19 is provided inside the inlet pipe 18. In this embodiment, there are four dust collection bags 15 and four inlet pipes 18. The inlet pipes 18 are evenly distributed on the lower outer peripheral wall of the distribution chamber 17. The distribution chamber 17 is detachably connected to the output end of the solenoid valve 16. A movable weighing component is provided on the frame 11 at the bottom of the dust collection bag 15. A drying component is provided inside the dust collection bag 15. When the compressed air backwash valve 14 in the filter cartridge 12 is activated for dust removal, the stripped dust falls into the bottom solenoid valve 16 under gravity. After the solenoid valve 16 is opened, the dust first enters the annular distribution chamber 17, which guides the dust to diffuse evenly. Then, the electric distribution valve 19 distributes the dust through the inlet pipe 18 to different dust collection bags 15 according to the instruction. This design achieves continuous dust removal and dynamic dust diversion. A movable weighing component weighs the dust collection bag 15 to determine the quality of the collected lint, while a drying component dries the lint to prevent fiber clumping and facilitate subsequent reuse. Furthermore, the device allows for the disassembly chamber 17 to be disassembled with the solenoid valve 16 closed, allowing the chamber and the fully loaded dust collection bag 15 to be moved via the movable weighing component. This facilitates the replacement of multiple dust collection bags 15 at once. This device avoids the production capacity loss caused by traditional downtime dust removal, and the multi-bag rotation mechanism significantly extends the single maintenance cycle, enabling dust collection bag 15 replacement without shutting down the system.

[0019] Reference Figure 1 To improve the quality of cotton lint recovery and facilitate lint collection, the bottom of the distribution chamber 17 is conical. The inlet pipe 18 is evenly connected to the outer periphery of the bottom of the conical distribution chamber 17. The drying assembly includes a drying bladder 20 located on one side of the bottom of the dust collection bag 15, filled with desiccant. The drying bladder 20 is connected to the dust collection bag 15 using Velcro. Plastic diaphragms are distributed on the inner wall of the dust collection bag 15. The plastic diaphragms on the inner wall of the dust collection bag 15 reduce fiber adhesion, facilitating subsequent use. The conical bottom structure of the distribution chamber 17 accelerates the sliding of dust into the inlet pipe 18, preventing accumulation. The removable drying bladder 20 continuously absorbs moisture, ensuring the dust remains in a low-humidity, loose state for easy recycling. The Velcro connection also facilitates the replacement of the drying bladder 20.

[0020] Reference Figure 1The mobile weighing assembly includes a platform 21 located at the bottom of the dust collection bag 15, with casters 22 at the bottom of the platform 21 and a handle 23 on one side. A storage tank 24 is located at the bottom of each dust collection bag 15 on the platform 21, and a weighing sensor is installed in the storage tank 24. A central controller is also provided. The electric distribution valve 19, solenoid valve 16, and weighing sensor are all electrically connected to the central controller. The storage tank 24 facilitates the carrying of individual dust collection bags 15. Simultaneously, the weighing sensor on the platform 21 monitors the weight of each dust collection bag 15 in real time, and the data is uploaded to the central controller. When the weight of a dust collection bag 15 approaches a threshold, the controller automatically adjusts the flow direction of the electric distribution valve 19, switching the dust to the low-load dust collection bag 15. This prevents the dust collection bag 15 from overloading and breaking, maximizes the utilization of the container volume, and reduces the frequency of manual intervention. The installation includes casters 22 and handles 23, which facilitate the removal of the distribution chamber 17 with the solenoid valve 16 closed when changing the dust bag 15, allowing the distribution chamber 17 and the fully loaded dust bag 15 to be moved via the platform 21.

[0021] Reference Figure 1 The inlet pipe 18 is equipped with a flexible connection, and the dust collection bag 15 is stacked on the weighing sensor. The flexible connection design compensates for displacement deviation, ensures that the dust conveying process is sealed, and at the same time ensures that the dust collection bag 15 will not generate excessive traction force during the dust collection process, thus extending the service life of each component.

[0022] Implementation Principle: This application has a simple structure. When the compressed air backwash valve 14 inside the filter cartridge 12 is activated for dust removal, the detached dust falls into the bottom solenoid valve 16 under gravity. After the solenoid valve 16 opens, the dust first enters the annular distribution chamber 17, which guides the dust to diffuse evenly. Subsequently, the electric distribution valve 19, according to the instruction, diverts the dust through the inlet pipe 18 to different dust collection bags 15. This design achieves continuous dust removal and dynamic dust diversion. Simultaneously, a moving weighing component is set to weigh the dust collection bags 15 to determine the quality of the collected lint. A drying component is also set to dry the lint, preventing cotton fiber clumping and facilitating subsequent reuse. Furthermore, the device can disassemble the distribution chamber 17 when the solenoid valve 16 is closed, allowing the distribution chamber 17 and the fully loaded dust collection bags 15 to be moved via the moving weighing component. This facilitates the replacement of multiple dust collection bags 15 at once, avoiding the production capacity loss caused by traditional downtime dust removal. The multi-bag rotation mechanism significantly extends the single maintenance cycle, enabling dust bag 15 replacement without shutting down the machine.

[0023] It should be noted that the connection relationships of components not specifically mentioned in this application are all assumed to be based on existing technology. Since they do not involve the inventive point and are commonly used in existing technology, the structural connection relationships are not described in detail.
