Description

Technical Field

[0001] This utility model relates to the field of glass fiber manufacturing, specifically a dust collection device for a water-drawing production line. Background Technology

[0002] In the glass fiber production process, after the water drawing process, continuous glass fibers need to be sent to a suspended cutting table. The cutting equipment on the cutting table cuts the fibers to a specific length, i.e., the yarn is cut. The cut yarn flows downwards from the cutting end of the cutting table into a vibrating screen. The vibrating screen removes fibers or impurities that do not meet size standards. The vibrating screen is an inclined trough with screen holes on its bottom wall. Non-standard waste fibers or impurities slide down the bottom wall into a waste fiber trough, while standard yarns fall through the screen holes and are conveyed by a conveyor belt below the vibrating screen. Currently, dust collection involves installing a suction pipe at the exhaust vent of the cutting equipment, above the cutting blade, to suck up dust and waste fibers. However, this suction pipe can only remove a portion of the dust and waste fibers generated during cutting. Other dust and waste fibers, as well as the sizing agent dust and waste fibers generated by the vibrating screen, cannot be effectively collected. This results in a pervasive atmosphere of sizing agent dust and waste fibers at the water drawing site, creating a poor working environment and impacting employee health. Summary of the Invention

[0003] This invention provides a dust collection device for a water-drawing wire production line, which can solve the problem of the large amount of dust and waste wire generated by existing water-drawing wire production lines causing a harsh working environment and affecting the health of employees.

[0004] The dust collection device for the water-based wire drawing production line of this utility model includes:

[0005] A dust collection enclosure is located below the yarn cutting table and forms a dust collection space. The dust collection space is connected to the yarn cutting opening of the yarn cutting table, and the vibrating screen of the water-drawing production line is located within the dust collection space.

[0006] The dust collection device includes a dust collection hood located above the vibrating screen, a dust collection pipe connected to the dust collection hood and communicating with the dust collection space, a filter installed in the dust collection pipe, and an exhaust fan communicating with the dust collection pipe. The dust collection hood is connected to the yarn cutting table and together they form the top of the dust collection space.

[0007] Preferably, the dust collection device further includes a dust cover, which covers the waste wire trough connected to the vibrating screen and forms a sealed space with the waste wire trough.

[0008] Preferably, the dust collection device further includes a waste filament guide pipe, one end of which is connected to the waste filament trough, and the other end extends to the waste filament collection device.

[0009] Preferably, the dust collection enclosure includes multiple vertical baffles, the upper end of which is connected to the top of the dust collection space and the lower end is connected to the ground. The dust collection enclosure also includes a soft curtain, the upper end of which is connected to the dust collection hood and the lower end of which hangs down at the connection between the vibrating screen and the waste wire trough.

[0010] Preferably, one of the vertical baffles opposite to the vibrating screen is a transparent baffle.

[0011] Preferably, the vertical baffle connecting the yarn cutting table to the ground is a detachable metal plate or a metal plate with an inspection door.

[0012] Preferably, the dust collection enclosure has a detection port at a position opposite to the vibrating screen, and the detection port is provided with a detection window that can be opened and closed.

[0013] Preferably, the filter includes a pre-filter and a pulse-jet cartridge dust collector located downstream of the pre-filter.

[0014] Preferably, the dust collection device further includes a partition, with the dust collection enclosure and dust collection hood located on one side of the partition, and the filter and exhaust fan located on the other side of the partition.

[0015] Preferably, the partition has an access passage between it and the conveyor belt that collects yarns that meet size standards, allowing the vibrating screen to pass through.

[0016] Compared with the prior art, this utility model has the following advantages: The dust and waste yarn at the yarn cutting nozzle of the water drawing production line dust collection device of this utility model are sucked downward into the dust collection space by the action of the induced draft fan. At the same time, the dust and waste yarn generated by the vibrating screen are also blocked in the dust collection space by the dust collection enclosure and cannot spread around. Then, the dust and waste yarn enter the filter through the dust suction pipe for filtration. The filtered air can be discharged into the workshop, thereby purifying the environment of the yarn cutting workplace and protecting the health of the workers. Attached Figure Description

[0029] This utility model provides a dust collection device for a water-drawing yarn production line, which is connected to a yarn cutting table 1. The yarn cutting table 1 is equipped with a yarn cutting device 2. The blade of the yarn cutting device 2, used to cut the yarn, is opposite to the cutting opening (not shown in the figure) of the yarn cutting table 1. After the yarn is cut, it falls through the cutting opening to a vibrating screen 8 below the yarn cutting table 1. The exhaust port 21 of the yarn cutting device 2 can be sealed. Figure 1 and Figure 2 As shown, the dust collection device includes a dust collection enclosure 3 and a dust suction device. The dust collection enclosure 3 is located below the yarn cutting table 1 and encloses a dust collection space. The dust collection space is connected to the yarn cutting opening of the yarn cutting table 1. The vibrating screen 8 of the water-drawing production line is located within the dust collection space. The dust suction device includes a dust collection hood 41 located above the vibrating screen 8, a dust suction pipe 42 connected to the dust collection hood 41 and communicating with the dust collection space, a filter installed in the dust suction pipe 42, and an induced draft fan 45 connected to the dust suction pipe 42. The dust collection hood 41 is connected to the yarn cutting table 1, together forming the top of the dust collection space.

[0030] Dust and waste yarn at the yarn cutting point are drawn downward into the dust collection space by the blower 45. At the same time, dust and waste yarn generated by the vibrating screen 8 are blocked in the dust collection space by the dust collection enclosure 3 and cannot spread around. Then, the dust and waste yarn enter the filter through the dust suction pipe 42 for filtration. The filtered air can be discharged into the workshop, thereby purifying the environment of the yarn cutting workplace and protecting the health of the workers.

[0031] The dust collection device also includes a dust cover 5, which covers the waste filament trough 6 connected to the vibrating screen 8, forming a sealed space to prevent waste filaments from scattering. In this embodiment, the dust cover 41 is made of transparent acrylic sheet, allowing observation of the waste filament trough 6 while creating a sealed environment. The dust collection device also includes a waste filament guide pipe 7, one end of which is connected to the waste filament trough 6, and the other end can extend into a waste filament collection device, such as a waste filament bin.

[0032] like Figure 2 As shown, the dust collection enclosure 3 includes multiple vertical baffles. The upper end of each vertical baffle is connected to the top of the dust collection space, and the lower end is connected to the ground. The dust collection enclosure 3 also includes a flexible curtain 31. The upper end of the flexible curtain 31 is connected to the dust collection hood 41, and the lower end hangs over the connection between the vibrating screen 8 and the waste filament trough 6. When the vibrating screen 8 is working normally, the flexible curtain 31 can block dust and waste filaments. When the vibrating screen 8 malfunctions, the flexible curtain 31 can be lifted to inspect or replace the vibrating screen 8.

[0033] In this embodiment, as Figure 3 As shown, at least one vertical baffle opposite to the vibrating screen 8 is a transparent acrylic baffle 32, which can serve as an observation window to observe the working status of the vibrating screen 8. The vertical baffle connecting the yarn cutting table 1 to the ground is a detachable metal plate 33 or a metal plate 33 with an inspection door, facilitating access to the dust collection space for maintenance of internal components. The dust collection enclosure 3 has a detection port 34 at a position opposite to the vibrating screen 8, and the detection port 34 has an openable and closable detection window (not shown in the figure), such as... Figure 2 As shown, this facilitates the removal of the yarn-cut product for inspection, such as checking whether the yarn has been cut.

[0034] The filter system includes a pre-filter 43 and a pulse-jet cartridge dust collector downstream of the pre-filter 43. The pre-filter 43 is easy to maintain and replace its filter material, while the pulse-jet filter 44 has a self-cleaning function. Exhaust gas first passes through the pre-filter 43 for initial interception of dust and lint. As the amount of intercepted material on the filter cotton gradually increases, the readings of the differential pressure gauges at the inlet and outlet of the device increase. When the threshold is reached, it indicates that the filter cotton needs to be replaced to ensure the efficiency of the pre-filter. The exhaust gas treated by the pre-filter 43 then enters the pulse-jet cartridge dust collector for further treatment. The pulse-jet cartridges can use membrane filter cartridges with a filtration accuracy of 0.3μm to intercept and remove fine dust particles with an interception efficiency of up to 99.99%. The exhaust gas treated by the cartridge dust collector contains almost no lint or impregnating agent dust and can be directly discharged into the workshop.

[0035] The dust collection device also includes a partition (not shown in the figure). The dust collection enclosure 3 and dust collection hood 41 are located on one side of the partition, and the filter and exhaust fan 45 are located on the other side of the partition. The partition includes a fixed upper partition and a lower partition detachable from the upper partition. The dust suction pipe 42 passes through the upper partition. The partition separates the filter of the dust collection device from the yarn cutting production equipment. In this embodiment, there is a maintenance passage between the partition and the conveyor belt that collects yarn conforming to size standards, allowing the vibrating screen 8 to pass through when it needs to be replaced.

[0036] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art within the spirit and scope of this utility model also fall within the scope of protection of this utility model.
