Description

Technical Field

[0001] This application relates to the technical field of static pressure chambers, and in particular to a static pressure chamber for use in glass fiber production workshops. Background Technology

[0002] Currently, plenum chambers are key components in the field of aerodynamics, primarily used to stabilize airflow, balance pressure distribution, and reduce noise. Their technical principle originates from the hydrostatic theory in fluid mechanics; by increasing the cross-sectional area of ​​the air duct, high-speed airflow is slowed down, converting dynamic pressure into static pressure, thereby achieving uniform airflow distribution and optimized system energy consumption.

[0003] In the production of glass fiber, processes such as drawing and impregnation have high requirements for airflow stability. In existing glass fiber production workshops, the fresh air ducts are usually staggered with the production equipment. Although this has some effect, the airflow speed is still relatively high, which will affect the product quality. Utility Model Content

[0004] This application provides a static pressure chamber for use in a glass fiber production workshop, which can reduce the impact on product quality, and adopts the following technical solution: A static pressure box for a glass fiber production workshop includes a box body connected to a fresh air duct, a first flow equalization perforated plate installed on the inner wall of the box body in an inverted V shape, and a second flow equalization perforated plate installed at the air outlet of the box body in a horizontal arrangement.

[0005] Preferably, the housing is equipped with a fixing mechanism for fixing the first flow equalization plate.

[0006] Preferably, the fixing mechanism includes a limiting plate and a support plate respectively disposed on both sides of the first flow equalization plate, and the limiting plate and the support plate are both bolted to the inner wall of the box.

[0007] Preferably, the outer wall of the enclosure is provided with multiple insulation layers.

[0008] Preferably, each insulation layer has multiple locking blocks fixed to the side near the box body, and the outer side wall of the box body has multiple locking slots, with each locking block corresponding to a locking slot.

[0009] Preferably, a filter mechanism is provided at one end of the fresh air duct inside the box.

[0010] Preferably, the filtration mechanism includes a threaded pipe threaded to one end of the fresh air duct at the housing, a filter pipe fixedly connected to the bottom of the threaded pipe, and a porous filter plate installed at the bottom of the filter pipe; the bottom of the filter pipe is provided with a settling groove, and the porous filter plate is bolted to the inner wall of the settling groove by countersunk bolts.

[0011] Preferably, a plurality of inclined sound-absorbing plates are bolted to the inner wall of the filter tube above the porous filter plate, and the plurality of sound-absorbing plates are arranged in a cross pattern.

[0012] Preferably, a connecting plate is fixedly connected to the end of the sound-absorbing plate, and a connecting groove is provided on the inner wall of the filter tube. The connecting plate is bolted to the connecting groove by countersunk bolts.

[0013] In summary, this application has the following beneficial effects: The housing design expands the cross-sectional area of ​​the air duct; the first and second flow equalization plates disperse the airflow. Therefore, the above solution reduces the airflow velocity, converts dynamic pressure into static pressure, and ensures uniform air distribution, thereby preventing turbulence from causing fiber scattering or breakage and reducing the impact on product quality.

[0019] This application discloses a static pressure chamber for use in a glass fiber production workshop, such as... Figure 1 and Figure 2As shown, the system includes a housing 2 connected to the fresh air duct 1, a first flow equalization plate 21 installed on the inner wall of the housing 2 in an inverted V shape, and a second flow equalization plate 22 installed horizontally at the air outlet of the housing 2 by countersunk bolts. The housing 2 expands the cross-sectional area of ​​the air duct; the first and second flow equalization plates 21 and 22 disperse the airflow. Therefore, this design reduces the airflow velocity, converts dynamic pressure into static pressure, and ensures uniform air distribution, thereby preventing turbulence from causing fiber scattering or breakage, and thus reducing the impact on product quality.

[0020] like Figure 1 and Figure 2 As shown, a fixing mechanism 3 for fixing the first flow equalization orifice plate 21 is installed inside the housing 2. The fixing mechanism 3 facilitates the fixing of the first flow equalization orifice plate 21.

[0021] like Figure 1 and Figure 2 As shown, the fixing mechanism 3 includes a limiting plate 31 and a support plate 32 respectively disposed on both sides of the first flow equalization plate 21. Both the limiting plate 31 and the support plate 32 are inclined and multiple in number. The limiting plate 31 and the support plate 32 are both bolted to the inner wall of the housing 2. When the first flow equalization plate 21 needs to be installed, the limiting plate 31 is first installed with bolts, then the first flow equalization plate 21 is moved upwards until it abuts against the limiting plate 31. Next, the support plate 32 is installed with bolts. In summary, the fixing mechanism 3 facilitates the installation of the first flow equalization plate 21.

[0022] like Figure 1 and Figure 2 As shown, the outer wall of the enclosure 2 is provided with multiple insulation layers 4. The insulation layers 4 are provided to facilitate the insulation of the enclosure 2.

The filter mechanism 5 includes a threaded pipe 51 vertically threaded to one end of the fresh air duct 1 in the housing 2, a filter pipe 52 fixedly connected to the bottom of the threaded pipe 51, and a porous filter plate 53 installed at the bottom of the filter pipe 52. The filter pipe 52 can be square as needed, and a groove 521 is opened at the bottom of the filter pipe 52. The porous filter plate 53 is bolted to the inner wall of the groove 521 by countersunk bolts. The threaded pipe 51, filter pipe 52, and porous filter plate 53 facilitate the filtration of the air entering the housing 2.

[0025] like Figure 2 and Figure 3 As shown, multiple inclined sound-absorbing plates 54 are bolted to the inner wall of the filter tube 52 above the porous filter plate 53, and the multiple sound-absorbing plates 54 are arranged in a cross manner; the sound-absorbing plates 54 can reduce noise on the one hand; on the other hand, the inclined arrangement of the sound-absorbing plates 54 can slow down the air flow speed, thereby providing a certain degree of protection for the porous filter plate 53.

[0026] like Figure 2 and Figure 3 As shown, a connecting plate 541 is fixedly connected to the end of the sound-absorbing plate 54, and a connecting groove 522 is provided on the inner wall of the filter tube 52. The connecting plate 541 is bolted to the connecting groove 522 by countersunk bolts. The connecting plate 541 and the connecting groove 522 facilitate the installation of the sound-absorbing plate 54.
