Description

Technical Field

[0001] This utility model relates to a wind tunnel drying device. Background Technology

[0002] Polyester spinning filament equipment performs melt spinning. In the chemical fiber industry, after the nascent filaments are ejected from the spinneret, they need to be cooled by air at a temperature of 20°C to finally form fibers. However, during long-term use of the air duct, spinning monomer polymers and silicone oil dripping onto the air duct during the cleaning of the spinneret will be generated on the inner wall of the air duct. This will eventually affect the uniformity of the air velocity in the air duct and thus affect the product quality. Therefore, the air duct needs to be replaced periodically and then washed with alkali, washed with water, and dried before it can be reused.

[0003] Currently, the cleaning process relies on personnel manually holding an 8kg compressed air hose to blow out the moisture inside and outside each individual air duct. During this process, workers operate in a noisy environment (the blowing generates significant noise) and need to use the air duct with a high grip for extended periods, leading to hand discomfort. Furthermore, with a large number of air ducts, manual cleaning takes a long time, resulting in low efficiency and poor cleaning effectiveness. Utility Model Content

[0036] Fan 1, heater 2, air distribution box 3, and air duct placement box 4 are connected in sequence. Fan 1 is configured to supply air to heater 2, and heater 2 is configured to heat the air. The heating temperature range is 50-60℃. Air distribution box 3 is provided with air distribution plate 5 extending vertically, which divides air distribution box 3 into a first box 31 and a second box 32 arranged in the left and right directions. The first box 31 is arranged adjacent to air duct placement box 4 and has a common side wall. The second box 32 is arranged adjacent to and connected to heater 2.

[0037] The duct placement box 4 includes a placement cavity, or the first box 31 and the duct placement box 4 are provided with a partition component, so that the duct placement box 4 forms multiple placement cavities and the first box 31 forms multiple ventilation cavities. The multiple ventilation cavities are distributed up and down along the height direction of the first box 31, and the ventilation cavities correspond one-to-one with the placement cavities and are connected accordingly.

[0038] The air duct placement box 4 is provided with multiple placement plates 19. The placement plates 19 are horizontally arranged and distributed vertically along the height direction of the air duct placement box 4. The placement plates 19 are configured to place the air ducts 21 to be dried. In some embodiments, the placement plates 19 are provided with multiple openings that penetrate the upper and lower sides of the placement plates 19, so that hot air can be quickly transferred to the air ducts 21 on the placement plates 19 through the openings.

[0039] In some embodiments, an air outlet 41 is provided on the upper side of the air duct placement box 4, and the air outlet is located at the end of the upper side of the air duct placement box 4 away from the wind distribution box 3.

The shielding door can be lifted to open the open side, making it convenient for personnel to operate and take out the air duct.

[0041] The air duct placement box 4, the first box 31, and the second box 32 all have opposite upper and lower sides, opposite front and rear sides, and opposite left and right sides. The front side of the air duct placement box 4 is on the same side as the front side of the first box 31, and the rear side of the air duct placement box 4 is on the other side as the rear side of the first box 31. The right side of the first box 31 is on the same side as the left side of the air duct placement box 4, or the left side of the first box 31 is on the same side as the right side of the air duct placement box 4.

[0042] The following three embodiments are set according to the number of placement cavities in the air duct placement box 4, as detailed below:

[0043] Example 1

[0044] The air duct placement box 4 includes a placement cavity, and the first box 31 has a ventilation cavity. After passing through the first box 31, the air enters the air duct placement box 4.

[0045] Example 2

[0046] See Figure 5-7 The air duct placement box 4 includes two placement cavities. The partition assembly includes a first horizontal partition 6, a first vertical partition 7, a second horizontal partition 8, and a second vertical partition 9. The first horizontal partition 6 and the second horizontal partition 8 can be parallel, and the first vertical partition 7 and the second vertical partition 9 can be parallel.

[0047] The first horizontal partition 6 is horizontally arranged inside the first housing 31, and the first vertical partition 7 is arranged on the common side of the first housing 31 and the air duct placement box 4, so that the first housing 31 is divided into a first ventilation chamber and a second ventilation chamber. One end of the first horizontal partition 6 is connected to the air distribution plate 5, and the other end of the first horizontal partition 6 is connected to the upper end of the first vertical partition 7 and is perpendicular to it. The lower end of the first vertical partition 7 extends downward and maintains a gap with the bottom wall of the air duct placement box 4 to form a ventilation channel.

[0048] On the common side of the first housing 31 and the air duct placement box 4, the upper end of the first vertical partition 7 and the inner top wall of the air duct placement box 4 are spaced apart to form a ventilation channel, and the lower end of the first vertical partition 7 and the lower side of the air duct placement box 4 are spaced apart to form a ventilation channel.

[0049] The second horizontal partition 8 and the second vertical partition 9 are both located inside the air duct placement box 4, thus dividing the air duct placement box 4 into a first placement cavity (see...). Figure 7 (m refers to) and the second placement cavity (see Figure 7 (as indicated by n in the text), the second horizontal partition 8 connects the first vertical partition 7 and the second vertical partition 9. One end of the second horizontal partition 8 is connected to the lower end of the first vertical partition 7 and is perpendicular to it. The other end of the second horizontal partition 8 is connected to the lower end of the second vertical partition 9 and is perpendicular to it. The upper end of the second vertical partition 9 extends upward to connect with the inner top wall of the air duct placement box 4. The first ventilation cavity and the first placement cavity are connected, and the second ventilation cavity and the second placement cavity are connected.

[0050] In this example, the front side, upper side, upper section of the common side of the first housing 31 and the air duct placement box 4 (located above the first vertical partition 7), the first vertical partition 7, the rear side, the second horizontal partition 8, and the second vertical partition 9 of the air duct placement box 4 enclose to form the first placement cavity. The front side, upper side, second vertical partition 9, second horizontal partition 8, left side (located below the first vertical partition 7), rear side, right side, and lower side of the air duct placement box 4 enclose to form the second placement cavity.

[0051] A portion of the airflow passing through the air distribution plate 5 first enters the first ventilation chamber, then the first placement chamber, with the airflow direction being horizontal. The other portion of the airflow passing through the air distribution plate 5 first enters the second ventilation chamber, then the second placement chamber, with the airflow directions being both vertical and horizontal. This allows for independent air intake in the first and second ventilation chambers while ensuring that the airflow volume in the two chambers is not significantly different. Even if the second placement chamber is further away from the air distribution box 3 than the first placement chamber, sufficient airflow is still guaranteed to enter the second placement chamber, ensuring that all air ducts within the placement box 4 can be dried effectively.

[0052] Example 3

[0053] See Figure 1-4 The air duct placement box 4 includes three placement cavities, namely the first placement cavity, the second placement cavity, and the third placement cavity; the partition assembly includes the first transverse partition 10, the second transverse partition 11, the third transverse partition 12, the fourth transverse partition 13, the first longitudinal partition 14, the second longitudinal partition 15, the third longitudinal partition 16, and the fourth longitudinal partition 17.

[0054] The first transverse partition 10 and the second transverse partition 11 are disposed inside the first housing 31. The first transverse partition 10 and the second transverse partition 11 are distributed sequentially in the vertical direction, that is, the first transverse partition 10 is located above the second transverse partition 11. Both the first transverse partition 10 and the second transverse partition 11 extend horizontally. The first longitudinal partition 14 and the second longitudinal partition 15 are distributed in the vertical direction on the common side of the first housing 31 and the air duct placement box 4, that is, the first longitudinal partition 14 is located above the second longitudinal partition 15. One end of the first transverse partition 10 and one end of the second transverse partition 11 are connected to the air distribution plate 5. The other end of the first transverse partition 10 and the other end of the second transverse partition 11 are respectively connected to the lower end of the first longitudinal partition 14 and the upper end of the second longitudinal partition 15. A gap is maintained between the upper end of the first longitudinal partition 14 and the inner top wall of the first housing 31 to form a ventilation channel. A gap is maintained between the lower end of the second longitudinal partition 15 and the inner bottom wall of the first housing 31 to form a ventilation channel. The first box 31 is divided into a first ventilation cavity, a second ventilation cavity, and a third ventilation cavity, which are distributed in sequence along the vertical direction by the first transverse partition 10, the second transverse partition 11, the first longitudinal partition 14, and the second longitudinal partition 15.

[0055] On the common side of the first housing 31 and the air duct placement box 4, a gap is maintained between the first longitudinal partition 14 and the second longitudinal partition 15 to form a ventilation channel, so that the second ventilation cavity is connected to the air duct placement box 4.

[0056] The third transverse partition 12, the fourth transverse partition 13, the third longitudinal partition 16, and the fourth longitudinal partition 17 are all disposed inside the air duct placement box 4. The third transverse partition 12 and the fourth transverse partition 13 extend horizontally, while the third longitudinal partition 16 and the fourth longitudinal partition 17 extend vertically. The third longitudinal partition 16 is closer to the first box 31 than the fourth longitudinal partition 17. The opposite ends of the third transverse partition 12 are connected to the upper ends of the first longitudinal partition 14 and the fourth longitudinal partition 17, respectively. A gap is maintained between the third transverse partition 12 and the inner top wall of the air duct placement box 4 to form a ventilation channel. The upper end of the third longitudinal partition 16 is connected to the third transverse partition 12. The fourth transverse partition 13 is located below the third transverse partition 12, and the opposite ends of the fourth transverse partition 13 are connected to the lower ends of the second longitudinal partition 15 and the third longitudinal partition 16, respectively. The lower end of the fourth longitudinal partition 17 is connected to the inner bottom wall of the air duct placement box 4.

[0057] The first placement cavity is formed by the left side, upper side, right side, bottom side, fourth longitudinal partition 17, third transverse partition 12, front side, and rear side of the air duct placement box 4. (See [reference]) Figure 4(a) The first placement cavity is connected to the first ventilation cavity. The first longitudinal partition 14, the second longitudinal partition 15, the third transverse partition 12, the third longitudinal partition 16, the fourth transverse partition 13, the front side of the air duct placement box 4, and the rear side of the air duct placement box 4 enclose and form the second placement cavity (see [reference]). Figure 4 (b) The second placement cavity is connected to the second ventilation cavity. The left side of the air duct placement box 4, the fourth transverse partition 13, the third longitudinal partition 16, the third transverse partition 12, the fourth longitudinal partition 17, the bottom side of the air duct placement box 4, the front side of the air duct placement box 4, and the rear side of the air duct placement box 4 enclose to form the third placement cavity (see...). Figure 4 c) The third placement cavity is connected to the third ventilation cavity.

[0058] The airflow passing through the air distribution plate 5 is divided into three parts before entering the air duct placement box. Specifically, a portion of the airflow passing through the air distribution plate 5 first enters the first ventilation chamber, then the first placement chamber, with the airflow direction being both vertical and horizontal. Another portion of the airflow passing through the air distribution plate 5 first enters the second ventilation chamber, then the second placement chamber, with the airflow direction being horizontal. The remaining airflow passing through the air distribution plate 5 first enters the third ventilation chamber, then the third placement chamber, with the airflow direction being horizontal. This division of airflow into the first, second, and third ventilation chambers ensures independent air intake for each chamber while maintaining relatively consistent airflow within each chamber. Even if the portions in the first and third placement chambers are further away from the air distribution plate 3 than the second placement chamber, sufficient airflow is still guaranteed for each chamber, ensuring good drying of the air ducts within the air duct placement box 4.

[0059] In this example, preferably, the device further includes a fifth longitudinal partition 18. The fifth longitudinal partition 18 is disposed on the side of the fourth longitudinal partition 17 away from the third longitudinal partition 16, and a gap is maintained between the fifth longitudinal partition 18 and the fourth longitudinal partition 17 to form a ventilation channel. The fifth longitudinal partition 18 is parallel to the fourth longitudinal partition 17. The upper end of the fifth longitudinal partition 18 is connected to the inner top wall of the air duct placement box 4, and the lower end of the fifth longitudinal partition 18 is maintained to the inner bottom wall of the air duct placement box 4 to form a ventilation channel. The advantage of setting the fifth longitudinal partition 18 is that the air flows from the first ventilation cavity along the left section of the first placement cavity to the gap between the fourth longitudinal partition 17 and the fifth longitudinal partition 18. The air moves down and then up to the right section of the first placement cavity (the right section places the air duct). In the right section of the first placement cavity, the air flows from bottom to top, which makes the air stay in the first placement cavity for a longer time, thereby making the air duct in the first placement cavity more thoroughly dried.

[0060] In some embodiments, the fan 1 is an axial flow fan. The impeller structure of the axial flow fan allows the gas to flow axially. This flow pattern allows a large amount of gas to pass through the fan 1, thus providing a large flow rate to the air duct placement box 4, ensuring sufficient flow to guarantee the drying effect. Within its operating range, the axial flow fan 1 can provide relatively stable pressure, allowing the gas to flow evenly in the air distribution box 3, which helps to ensure ventilation stability and reliability. The axial flow fan includes components such as an impeller, casing, and motor, without complex transmission devices and housing structures. Its simple structure makes the manufacturing and maintenance costs of the axial flow fan relatively low, and it is easy to install and can be put into use quickly. It is also highly efficient and has low noise, providing a quieter working environment and reducing noise pollution to personnel.

[0061] In this example, the core component of heater 2 is the heating element, which is a stainless steel heating tube. The stainless steel heating tube consists of a resistance wire sealed inside a metal tube filled with magnesium oxide insulating material, providing excellent insulation and heat dissipation. The resistance wire is typically made of materials such as nickel-chromium alloy, and heat is generated by the flow of current through it. Heater 2 includes a temperature controller, a relay, and a fuse. The temperature controller is used to set and control the heating temperature; when the set temperature is reached, it automatically cuts off the power or adjusts the heating power. The relay controls the on / off state of the circuit, and the fuse quickly cuts off the power supply in case of overload or short circuit, providing protection.

[0062] In some embodiments, the device further includes an air filter 20, which is connected to the fan 1.

[0063] The air filter 20 includes an outer frame and filter bags. The outer frame is typically made of aluminum, and the filter bags are arranged in a W-shape to increase the filtration area while reducing resistance. The filter bags are made of fiberglass, which has advantages such as high filtration efficiency, low resistance, and large dust holding capacity. It can effectively filter airborne particles larger than 0.5 microns, can withstand high temperatures, and ensures air cleanliness. Each filter bag has an aluminum groove at the front and a metal fastener at the rear to prevent it from breaking due to wind shear friction at high air velocities. Each filter bag edge is sealed with a sealing strip, providing good airtightness and bonding strength, preventing air leakage or breakage.

[0064] The implementation method of the air duct drying device in this example is as follows: the outside air passes through the air filter to filter the air clean, and the fan then sends the air to the heater for heating. The hot air passes through the air distribution box to deliver the air evenly to the air duct placement box for thermal convection. The air ducts in the air duct placement box are dried by the hot air.

[0065] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
