Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, in particular to an automatic dust removal device for processing of new textile materials. BACKGROUND

[0002] The processing and manufacturing of new textile materials are the core links of modern fiber industry and high-tech textile industry, which cover multiple continuous and automatic processes such as polymer chip, spinning forming, drafting heat setting, and winding packaging. With the rapid development of industrial textiles, high-performance fibers and functional composite materials, the requirements for raw material purity, process environment cleanliness and product quality stability in the processing process are increasingly stringent. Currently, mainstream processing equipment generally uses high-speed melt spinning, pneumatic traction and high-pressure winding technology, and the production line running speed continues to increase, the material throughput per unit time significantly increases, and the entire processing chain presents the characteristics of high integration, continuity and precision, which puts higher requirements on the response ability and reliability of the supporting auxiliary system.

[0003] In the above-mentioned processing of new textile materials, the fiber bundle and its surface inevitably carry and produce various forms of production dust and fine impurities. These dusts mainly come from the residual oligomer debris in the raw materials, the condensed particles after the volatilization of the spinning oil, the fine fiber debris generated by the friction between the fiber and the guide device under high-speed operation, and the suspended dust in the ambient air. If these dust-containing substances cannot be removed from the processing path in time and effectively, the dust particles will adhere to the surface of the fiber or embed in the inside of the fiber bundle, which not only directly deteriorates the appearance uniformity and mechanical properties of the finished product, but also may form scorching spots in the subsequent heat setting or dyeing and finishing processes, thereby reducing the product grade. In addition, a large amount of dispersed dust accumulated on the surface of the equipment and electrical components will also accelerate mechanical wear, interfere with the detection accuracy of online sensors, and increase the frequency of downtime maintenance, thereby having a significant adverse effect on production continuity and overall operating cost. Therefore, embedding an efficient and stable dust removal link in the processing flow of new textile materials has become a necessary technical means to ensure product quality and reliable operation of equipment.

[0004] Currently, for the dust removal needs in the processing of new textile materials, the industry generally sets up suction ports at key workstations, and transports the dust-containing airflow to centralized or single-machine dust removal devices for treatment through negative pressure pipelines. Common dust removal devices include cyclone separation dust removal device, cloth bag filter dust removal device, and filter cartridge dust removal device, etc. However, in actual production conditions, the existing dust removal devices generally have the problems of low running efficiency and insufficient adaptability. SUMMARY

[0005] In order to at least solve one of the above technical problems, the purpose of the present application is to provide an automatic dust removal device for processing of new textile materials, which improves the dust removal efficiency and effect.

[0006] To achieve the above object, the present application provides the following technical scheme:

[0007] The utility model provides a kind of automatic dust removal device for processing new textile material, including collection box, the first vertical pipe is communicated with in one side of the top of collection box, the first horizontal pipe is communicated with in another end of the first vertical pipe, flexible telescopic pipe is communicated with in another end of the first horizontal pipe, the bottom of the flexible telescopic pipe is connected with the collection cover of outer expansion, fixed frame is fixedly connected with in the side of collection box close to the collection cover, telescopic mechanism is arranged between the fixed frame and the collection cover, the telescopic mechanism includes electric telescopic component and at least one sliding telescopic rod, respective one end of the electric telescopic component and the sliding telescopic rod is connected with the fixed frame, and respective other end thereof is connected with the collection cover, first negative pressure generating device is arranged in the top of collection box, the air inlet of the first negative pressure generating device is communicated with the top of collection box, first isolation net is installed at the air inlet of the first negative pressure generating device.

[0008] Preferably, the electric telescopic component is an electric cylinder.

[0009] Preferably, the collection box is hingedly connected with a cleaning door with a lock.

[0010] Preferably, the cleaning door is provided with a vertical strip-shaped observation window.

[0011] Preferably, the first horizontal pipe and the flexible telescopic pipe are provided with a second negative pressure generating device at the connection, the air inlet of the second negative pressure generating device is communicated with the first horizontal pipe, the second negative pressure generating device is provided with a second isolation net at the air inlet, the second negative pressure generating device is electrically connected with a control unit, the control unit is provided with a timer, and the control unit controls the second negative pressure generating device to start and stop intermittently according to the signal of the timer.

[0012] Preferably, the collection box is provided with a blocking net, which is used to block the dust accumulated at the bottom of the collection box from being raised again under the action of air flow.

[0013] Preferably, the collection box is provided with universal wheels with self-locking devices at the four corners.

[0014] The present application has the following advantages:

[0015] I. Improve the dust removal efficiency and automation degree; the application generates continuous negative pressure through the first negative pressure generating device, cooperates with the first vertical pipe, the first horizontal pipe and the flexible telescopic pipe to form a closed negative pressure suction channel, so that the collecting cover can actively and continuously suck and collect the dust generated in the processing of new textile materials. At the same time, the cooperation of the electric telescopic component and the sliding telescopic rod in the telescopic mechanism enables the collecting cover to automatically extend and retract according to the actual position of the processing station or the direction of the fiber bundle, so that the collecting cover can maintain the best distance and angle with the dust generating point without frequent manual intervention, ensuring that the negative pressure suction effect is always concentrated in the high concentration dust area, significantly improving the response speed and suction efficiency of the dust removal device to dynamic production conditions, thereby effectively reducing the possibility of dust escaping into the surrounding environment.

[0016] II. Improve the stability and continuity of dust removal effect; the first isolation net installed at the air inlet of the first negative pressure generating device can effectively intercept large particle impurities or fiber fragments sucked in with the airflow, preventing them from entering the inside of the negative pressure generating device and causing impeller wear or airflow passage blockage, thereby ensuring the stability of the air intake flow and vacuum degree of the negative pressure generating device during long-term operation. Cooperate with the collecting box as a dust temporary storage space, so that the dust-containing airflow first passes through the tank expansion and deceleration before entering the negative pressure generating device, and part of the heavier dust particles naturally settle at the bottom of the tank, reducing the burden of the subsequent filter element. The above-mentioned structure cooperates to make the dust removal device still maintain a high dust capture ability during long-time continuous operation, avoiding the attenuation of dust removal effect caused by internal dust accumulation or component damage.

[0017] III. Reduce the risk of secondary dust raising and cross contamination; the blocking net arranged in the collecting box can effectively prevent the settled dust at the bottom of the tank from being raised again when the airflow fluctuates or the negative pressure changes, avoiding the dust from entering the suction channel again or escaping to the external environment. This structure design combined with the closed cavity of the collecting box enables the captured dust to be stably stored in the tank, and will not cause secondary dispersion due to equipment vibration or start-stop operation. At the same time, the connection structure of the flexible telescopic pipe and the collecting cover allows the collecting cover to move flexibly between different stations, reducing the dust escape caused by the fixed air inlet due to too far distance, further ensuring the air cleanliness of the processing area, which is conducive to reducing the adverse effects of dust on the surface quality of fiber products and subsequent processes.

[0018] IV. Optimizing energy consumption control and operational economy; the second negative pressure generating device is arranged at the connection between the first horizontal pipe and the flexible expansion pipe, with its air inlet being in communication with the first horizontal pipe and being provided with a second isolation net, and being electrically connected with a control unit provided with a timer. The control unit controls the intermittent start and stop of the second negative pressure generating device according to the timer signal. This design enables the dust removal device to automatically reduce or suspend the auxiliary negative pressure output during periods or process gaps with less dust generation, and only start the second negative pressure generating device when it is necessary to enhance the suction force. Compared with the continuous full-load operation mode, this intermittent operation mode effectively reduces the overall power consumption, prolongs the service life of the negative pressure generating equipment, and reduces the replacement frequency of the filter element, thus achieving significant energy saving and consumption reduction effects.

[0019] V. Enhancing the convenience of device maintenance and the visibility of operation; a cleaning door with a lock is hinged on one side of the collection box. The operator can regularly open the cleaning door to clean the dust deposited in the box, without the need to disassemble the pipeline or move the entire equipment, thus achieving simple and convenient maintenance operation. The vertical strip-shaped observation window arranged on the cleaning door enables the operator to directly observe the dust accumulation height in the box and the state of the internal filter components without opening the cleaning door, thus facilitating timely arrangement of cleaning work and avoiding the influence of overfull dust accumulation on the dust removal effect or causing blockage. In addition, the universal wheels with self-locking devices arranged at the four corners of the bottom of the collection box enable the entire dust removal device to be flexibly moved and positioned between different processing equipment or different workstations, thus enhancing the applicability and turnover efficiency of the equipment in the production mode of multiple varieties and small batches of textile new materials.

[0020] VI. Multiple filtration protection and equipment safety guarantee; the combination of the first isolation net and the second isolation net forms two protective barriers at the air inlet of the negative pressure generating device. The first isolation net intercepts large-sized impurities entrained in the airflow entering the collection box, and the second isolation net further filters fine particles in the auxiliary negative pressure section, both of which cooperatively protect the core moving components of the negative pressure generating device from dust erosion. At the same time, the blocking net inhibits the dust accumulation at the bottom of the box, thus reducing the frictional contact between the dust and the inner wall of the box and the air outlet. The above-mentioned multi-level protection structure collectively reduces the internal wear and failure probability of the equipment, improves the operational reliability and safety of the dust removal device under harsh working conditions such as high-speed spinning and high dust concentration, and indirectly guarantees the continuous and stable operation of the textile new material production line.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0026] As shown in Figs. 1-2 A kind of automatic dust removal device for processing new textile material, including collecting box 1, the top side of collecting box 1 is communicated with first vertical pipe 101, first vertical pipe 101 other end is communicated with first horizontal pipe 102, first horizontal pipe 102 other end is communicated with flexible telescopic pipe 103, the bottom of flexible telescopic pipe 103 is connected with the collecting cover 104 of outer expansion, collecting box 1 is fixedly connected with fixed frame 201 close to collecting cover 104 side, telescopic mechanism is arranged between fixed frame 201 and collecting cover 104, telescopic mechanism includes electric telescopic assembly 221 and at least one sliding telescopic rod 222, the respective one end of electric telescopic assembly 221 and sliding telescopic rod 222 is connected with fixed frame 201, its respective other end is connected with collecting cover 104, collecting box 1 top is provided with first negative pressure generating device 301, the air inlet of first negative pressure generating device 301 is communicated with the top of collecting box 1, first negative pressure generating device 301 is installed with first isolation net 302 at air inlet.

[0027] As shown in Figs. 1-2As shown, after the first negative pressure generating device 301 is started, its air inlet extracts air from the top of the collection tank 1, forming a continuous negative pressure environment inside the collection tank 1, the first vertical pipe 101, the first horizontal pipe 102, the flexible expansion pipe 103 and the collection cover 104. Since the collection cover 104 is located at the end of the flexible expansion pipe 103 and has an outwardly expanding shape, it has a large opening area and can cover the main area where dust is generated during the processing of new textile materials. Under the action of negative pressure, the surrounding dust-containing air is sucked into the collection cover 104, and then passes through the flexible expansion pipe 103, the first horizontal pipe 102 and the first vertical pipe 101 into the collection tank 1. This closed negative pressure suction path ensures that the dust is actively and directionally transported from the generation point to the collection tank 1, avoiding the free diffusion of dust to the surrounding working space, and realizing the source capture and centralized transportation of dust.

[0028] The first isolation net 302 is arranged at the front end of the air inlet of the negative pressure generating device. When the dust-containing airflow approaches the air inlet under the action of negative pressure, the larger particle size dust, fiber debris or hard impurities carried in the airflow are physically intercepted by the isolation net and cannot enter the inside of the negative pressure generating device. This protective measure prevents impurities from impacting or rubbing the impeller, motor and shell wall of the negative pressure generating device, avoiding damage to the equipment or blockage of the airflow passage caused by foreign matter intrusion. At the same time, the isolation net only intercepts large particles, while allowing fine dust to pass through the airflow, ensuring the continuity of the negative pressure suction function, so that the dust removal device maintains stable air suction flow and negative pressure value during long-term operation.

[0029] The fixed frame 201 is installed on the side of the collection tank 1 as a support base, and the telescopic mechanism connects the fixed frame 201 and the collection cover 104. The electric cylinder is used as an electric telescopic component 221, and after receiving a control signal, the telescopic rod of the electric cylinder can extend or retract along the axial direction, and at the same time, the sliding telescopic rod 222 synchronously slides with the action of the electric cylinder, together guiding the collection cover 104 to produce displacement relative to the fixed frame 201 and the collection tank 1. Since the collection cover 104 is connected to the first horizontal pipe 102 through the flexible expansion pipe 103, the flexible expansion pipe 103 can bend or deform by stretching and contracting with the movement of the collection cover 104, and will not hinder the position adjustment of the collection cover 104. Through the precise control of the electric cylinder, the collection cover 104 can automatically adjust to the position closest to the dust source and with the best suction effect according to the direction of the fiber bundle in the processing station, the material passing height or the change of the dust emission point, reducing the loss of suction caused by the collection cover 104 being too far away or the angle deviation, and ensuring the pertinence and effectiveness of the dust removal effect in the dynamic production process.

[0030] As shown in FIG. 6, the first negative pressure generating device 301 is connected to the first horizontal pipe 102 through the flexible expansion pipe 103, and the first horizontal pipe 102 is connected to the first vertical pipe 101 through the flexible expansion pipe 103. The first vertical pipe 101 is connected to the collection tank 1 through the flexible expansion pipe 103. Figs. 1-2As shown, the connection between the first horizontal pipe 102 and the flexible expansion pipe 103 is provided with a second negative pressure generating device 401, the air inlet of the second negative pressure generating device 401 is connected with the first horizontal pipe 102, the air inlet of the second negative pressure generating device 401 is provided with a second isolation net 402, the second negative pressure generating device 401 is electrically connected with a control unit 403, the control unit 403 is provided with a timer, and the control unit 403 controls the intermittent start and stop of the second negative pressure generating device 401 according to the signal of the timer.

[0031] The second negative pressure generating device 401 is installed at the connection position of the first horizontal pipe 102 and the flexible expansion pipe 103, and the air inlet thereof is communicated with the inside of the first horizontal pipe 102. When the second negative pressure generating device 401 is started, it generates additional suction force in the first horizontal pipe 102, which enhances the airflow speed and negative pressure intensity from the collecting cover 104 to the section of the first horizontal pipe 102 through the flexible expansion pipe 103, and is beneficial to quickly sucking high-concentration or difficult-to-catch fine dust. The second isolation net 402 also plays a role in protecting the second negative pressure generating device 401 from being invaded by large-particle impurities. The timer in the control unit 403 sends a signal according to the preset time period, and the control unit 403 controls the second negative pressure generating device 401 to start and stop intermittently according to the signal, that is, it is automatically turned on during the peak period of dust generation or the period when strong suction is needed, and it is automatically turned off during the period when less dust is generated or no additional suction is needed. This intermittent working mode can provide auxiliary suction force to enhance the dust removal effect when necessary, and avoid energy waste and equipment wear caused by long-term continuous operation.

[0032] As shown in Figs. 1-2 The collecting box 1 is provided with a blocking net 105, which is used to block the dust accumulated at the bottom of the collecting box 1 from being raised again by the airflow. After the dust-containing airflow enters the collecting box 1 from the first vertical pipe 101, the airflow speed decreases due to the significant expansion of the space inside the box compared with the pipeline, and most of the heavy or large-particle-size dust particles are deposited at the bottom of the collecting box 1 under the action of gravity. The blocking net 105 is arranged inside the collecting box 1 and located between the deposition area and the air outlet. When the negative pressure generating device is continuously running or the airflow fluctuates at the start-stop moment, the bottom dust has a tendency to be raised by the rising airflow. At this time, the blocking net 105 changes the local airflow direction and reduces the disturbance flow speed through its mesh structure, so that the raised dust particles are intercepted again and fall back to the bottom of the box, thereby preventing the already deposited dust from entering the first isolation net 302 or the suction passage again with the airflow, ensuring the cleanliness of the exhaust air, and reducing the filtration load of the first isolation net 302.

[0033] As shown in Figs. 1-2As shown, the cleaning door 106 is hinged on one side of the collection box 1 with a lock. A vertical strip-shaped observation window 107 is arranged on the cleaning door 106. The cleaning door 106 is connected to the side of the collection box 1 through a hinge. An operator can open the cleaning door 106 by unlocking and rotating it, thereby directly exposing the internal space of the collection box 1, facilitating the use of tools or manual methods to clean the dust deposited on the bottom of the box. After cleaning, the cleaning door 106 is closed and locked to ensure the air tightness of the collection box 1 during operation. The vertical strip-shaped observation window 107 penetrates the cleaning door 106 and is made of transparent material. An operator can directly observe the height, color and surface attachment of the dust accumulation in the box through the observation window 107 without opening the cleaning door 106. This allows maintenance personnel to determine the cleaning time in a timely manner, avoiding the reduction of the effective volume of the box, the obstruction of the airflow channel or the blockage of the blocking net 105 due to excessive dust accumulation, thereby maintaining the long-term stable operation of the dust removal device.

[0034] As shown in Figs. 1-2 The four universal wheels 5 are installed at the bottom of the collection box 1, and each universal wheel 5 has independent rotating function, so that the collection box 1 can be pushed and moved in any direction on the ground. When the dust removal device needs to be transferred from one processing station to another or adjusted in the same station, an operator can push the collection box 1 to make the universal wheels 5 roll to achieve flexible movement. After reaching the predetermined position, the self-locking device of each universal wheel 5 is started to lock the wheel from rotating, thereby fixing the collection box 1 to the ground to prevent accidental displacement when the negative pressure generating device is running or externally touched. This moving and positioning function enhances the commonality and flexibility of the dust removal device in different production lines or different processing procedures.

[0035] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited to this. Any simple change, equivalent replacement or modification made on the basis of the present application to solve the same technical problem and achieve the same technical effect is covered by the protection scope of the present application.
