Description

Technical Field

[0001] This utility model relates to the field of spinning production technology, and more specifically to an impeller cleaning system for an electrostatic dust removal fan used in spinning workshops. Background Technology

[0002] In the process of chemical fiber spinning, after the molten polymer is extruded through the spinneret, it needs to be rapidly cooled and solidified by the quench air system to form nascent fibers. During this process, ultrafine fiber fragments will be generated due to the breakage of the fiber bundle or mechanical friction. These fragments have the characteristic of being easily suspended in mass. In addition, due to the high temperature volatilization of spinning oil and the combination of low molecular weight organic matter released from the polymer, a viscous aerosol can be formed.

[0003] For the pollutants mentioned above, existing spinning workshops generally use electrostatic dust removal equipment to purify dusty air. Spinning dust has strong oleophilicity and low conductivity. When the humidity of the workshop environment is below 40%RH, the dust charging efficiency decreases significantly, resulting in insufficient electrostatic adsorption. Summary of the Invention

[0004] To address the technical problems existing in dust removal fans in spinning workshops, the first aspect of this utility model proposes an impeller cleaning system for electrostatic dust removal fans used in spinning workshops, comprising:

[0005] The base is installed in the spinning workshop;

[0006] A drive structure is mounted on the base, and a centrifugal impeller is connected to the output end of the drive structure.

[0007] An impeller cover, connected to the base, covers the outside of the centrifugal impeller, and the impeller cover is provided with an air inlet pipe and an exhaust pipe. An air inlet channel is formed on the inner side of the air inlet pipe, which is directly opposite the center of the centrifugal impeller. When the centrifugal impeller is driven to rotate by the drive structure, a negative pressure is formed at the air inlet channel, which causes the airflow to be drawn into the impeller cover and discharged through the exhaust pipe.

[0008] The bottom of the impeller shroud is provided with a spray structure, which is used to spray water mist onto the bottom of the impeller chamber inside the impeller shroud so that the gas entering the impeller chamber is humidified before being discharged through the exhaust pipe.

[0009] The bottom of the impeller shroud is also provided with an openable cover. When the cover is opened, the notch on the impeller shroud forms a maintenance window connecting the impeller chamber and the external environment.

[0010] Preferably, in the impeller chamber, the airflow flows from the intake area to the exhaust area along an arc-shaped path, and the notch is provided between the intake area and the exhaust area.

[0011] Preferably, the notch is located below the impeller shroud near the exhaust pipe.

[0012] Preferably, the notch is located in the lower region of the impeller shroud.

[0013] Preferably, the lowest edge of the notch is lower than the lowest point of the centrifugal impeller.

[0014] Preferably, the cover is connected to the impeller cover by any one or more of a threaded connection, a hinge, or a pin structure.

[0015] Preferably, the cover is constructed as an arc-shaped plate structure.

[0016] Preferably, the outer edge of the arc-shaped plate structure is provided with multiple openings, and the outer periphery of the notch of the impeller cover is provided with multiple screw holes. The arc-shaped plate structure and the impeller cover are fixed by passing screws through the openings and fixing them into the screw holes.

[0017] Preferably, the spray structure includes a water supply pipe and an atomizing nozzle. The water supply pipe extends into the impeller chamber, and the atomizing nozzle is connected to the outlet end of the water supply pipe to form a water mist in the impeller chamber.

[0018] Preferably, the nozzle of the atomizing nozzle is oriented towards the exhaust area, and the atomizing nozzle is located below the notch.

[0019] The impeller cleaning system for the electrostatic precipitator fan in the spinning workshop, as described in the above embodiments, increases the humidity of the impeller chamber by installing a spray device at the bottom of the dust collector fan. This humidifies the gas before it exits through the exhaust pipe, increasing the resistivity of the spinning dust and facilitating its adsorption in the subsequent electrostatic field, thus improving dust removal efficiency. Simultaneously, the addition of an openable cover at the bottom of the impeller chamber allows operators to more easily clean the dust accumulated inside, reducing equipment downtime.

[0024] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0025] Combination Figure 1 As shown, the first aspect of this utility model proposes an impeller cleaning system for an electrostatic dust removal fan used in a spinning workshop, including a base 10, a drive structure 20, a centrifugal impeller 30, an impeller cover 40, a spray structure, and a cover 60.

[0026] It should be understood that the base 10 is located in the spinning workshop; the drive structure 20 is mounted on the base 10, and the output end of the drive structure 20 is connected to the centrifugal impeller 30. The impeller cover 40 is connected to the base 10 and covers the outside of the centrifugal impeller 30.

[0027] like Figure 1 and Figure 2 As shown, the impeller cover 40 is provided with an air inlet pipe 41 and an exhaust pipe 44. An air inlet channel 42 is formed on the inner side of the air inlet pipe 41, which is directly opposite the center of the centrifugal impeller 30. When the centrifugal impeller 30 is driven to rotate by the drive structure 20, a negative pressure is formed at the air inlet channel 42, which causes the airflow to be drawn into the impeller cover 40 and discharged through the exhaust pipe 44.

[0028] The air intake pipe 41 is connected to the workshop's air intake system, and the exhaust pipe 44 is connected to the high-voltage electrostatic field unit for electrostatic dust removal.

[0029] To increase the humidity of the air entering the impeller shroud 40, a spray structure is provided at the bottom of the impeller shroud 40. The spray structure is used to spray water mist onto the bottom of the impeller chamber 401 inside the impeller shroud 40, so that the gas entering the impeller chamber 401 is humidified before being discharged through the exhaust pipe 44.

[0030] Thus, the increased humidity inside the impeller chamber 401 increases the resistivity of the spinning dust passing through the impeller chamber 401, making it easier for the dust to be adsorbed in the subsequent high-voltage electrostatic field unit.

[0031] Due to the high humidity inside the impeller chamber 401, the amount of dust adhering to the surface of the centrifugal impeller 30 (which can be thrown to the inner wall of the impeller cover 40 by centrifugal force after adhering to the liquid film) will increase compared to before, especially the inner wall of the impeller cover 40. Therefore, it is necessary to facilitate cleaning.

[0032] Therefore, the bottom of the impeller cover 40 is also provided with an openable cover 60. When the cover 60 is opened, the notch 43 on the impeller cover 40 forms a maintenance window connecting the impeller chamber 401 and the external environment.

[0033] Thus, the user can open the cover 60 to expose the notch 43, and then use tools to clean the bottom of the impeller chamber 401 and the surface of the centrifugal impeller 30 before closing the cover 60.

[0034] Furthermore, in combination Figure 2 and Figure 3As shown, the airflow in the impeller chamber 401 flows from the intake area 402 along an arc-shaped path to the exhaust area 403, and the notch 43 is provided between the intake area 402 and the exhaust area 403.

[0035] Preferably, the notch 43 is located on the impeller shroud 40 below the exhaust pipe 44. The notch 43 is located in the lower region of the impeller shroud 40.

[0036] Thus, the notch 43 is positioned closer to the bottom of the impeller shroud 40, and there is more space below the exhaust pipe 44, which allows the operator to have more operating space inside the notch 43 and avoids interference between the tools and the impeller shroud 40 or the centrifugal impeller 30.

[0037] Combination Figure 2 and Figure 3 As shown, the lowest edge 431 of the notch 43 is lower than the lowest point of the centrifugal impeller 30.

[0038] In this way, rod-shaped tools such as scrapers can be fully inserted into the bottom of the impeller cover 40 and complete the operation of scraping impurities from the bottom up to the outside of the notch 43.

[0039] In an alternative embodiment, the cover 60 is connected to the impeller shroud 40 by any one or more of a threaded connection, a hinge, or a pin structure.

[0040] Combination Figure 4 As shown, the cover 60 is constructed as an arc-shaped plate structure 61.

[0041] The arc-shaped plate structure 61 has multiple openings 63 along its outer edge, and the impeller cover 40 has multiple screw holes around its notch 43. Screws are passed through the openings 63 and fixed into the screw holes to secure the arc-shaped plate structure 61 and the impeller cover 40. A handle 62 is also provided on the outer side of the arc-shaped plate structure 61.

[0042] Thus, when it is necessary to remove the cover 60, unscrew all the screws and use the handle 62 to remove the cover 60, or remove the screws until only the last one remains, and then rotate the cover 60 around the screw as an axis to expose the notch 43.

[0043] In the above embodiments, the spray structure includes a water supply pipe 50 and an atomizing nozzle 51. The water supply pipe 50 extends into the impeller chamber 401, and the atomizing nozzle 51 is connected to the water outlet of the water supply pipe 50 to form water mist in the impeller chamber 401.

[0044] The nozzle of the atomizing nozzle 51 faces the exhaust area 403, and the nozzle 51 is located below the notch 43.

[0045] In this way, the spray generated by the atomizing nozzle 51 can come into contact with the airflow that is about to enter the exhaust area 403, thereby humidifying and reducing the amount of water vapor remaining in the impeller chamber 401. This design can reduce the cleaning frequency.

[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
