Abstract
Description
Technical Field
[0001] The present invention relates to the field of main network devices, and in particular to a main network device base that saves energy and reduces consumption. Background Art
[0002] The main network device is one of the important components of the spinning machine. Its function is to network the yarn bundles after they have been oiled, stretched and other processes, so as to increase the cohesion of the yarn bundles, thereby achieving the purpose of no twisting and no sizing, which can effectively shorten the process flow during spinning manufacturing.
[0003] The existing main network device includes a main network device body 2 and a matching base 1. An air inlet 11 is opened on the base 1 to communicate with the wire guide hole 21 of the main network device body 2. High-pressure gas is blown into the wire guide hole 21 through the air inlet 11, generating a rotating vortex inside the wire guide hole, so that the single wires in the wire bundle passing through the wire guide hole are intertwined with each other, thereby forming a network knot and performing network processing on the wire bundle.
[0004] The compressed air pressure requirement of existing products is 0.35MPa. However, the existing air inlet 11 is a straight-through structure. This structure will cause air flow friction when the air flows, and turbulence dissipates energy. The dynamic pressure cannot be effectively converted into static pressure, making the outlet static pressure significantly lower than the inlet air pressure, resulting in a large total pressure loss, which leads to a drop in the overall system pressure. Summary of the Invention
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an energy-saving and consumption-reducing main network device base to solve the problems existing in the above-mentioned background technology.
[0006] The present invention provides the following technical solution: an energy-saving and consumption-reducing main network device base, comprising a base, which is used in conjunction with a main network device body, a wire guide hole being provided on the main network device body, a mounting hole for assembling a nozzle being provided on the base, and at least one air inlet being adapted to and connected with the wire guide hole being provided on the mounting hole, the air inlet being an hourglass-shaped structure, one end of which is adapted to and connected with the wire guide hole, and the other end of which is connected with the mounting hole.
[0007] Preferably, the air inlet hole includes a first conical hole and a second conical hole, the expanded end of the first conical hole is connected to the mounting hole, and the expanded end of the second conical hole is connected to the guide wire hole, so that the contracted ends of the first conical hole and the second conical hole are connected to form an hourglass-shaped structure.
[0008] Preferably, an arc chamfer is provided at the connection between the first tapered hole and the second tapered hole.
[0009] Preferably, the diameter of the second tapered hole is at least twice that of the first tapered hole.
[0010] Preferably, the number of the air inlet holes and the wire guide holes are both two, and the two air inlet holes and the wire guide holes correspond to each other and are connected to form two independent air flow ducts.
[0011] Preferably, one end of the two air inlet holes is connected to a mounting hole, so that the two air inlet holes share one air pressure nozzle.
[0012] Preferably, the base 1 is made of aluminum alloy.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The air inlet of the present invention adopts an hourglass-shaped structure, replacing the traditional straight-through air inlet, so that the air inlet forms a Venturi effect. When air passes through the narrow section of the hourglass-shaped structure, the cross-sectional area decreases and the flow rate accelerates. According to Bernoulli's principle, the increase in flow rate will cause the static pressure in the area to decrease, but the dynamic pressure to increase. In the expansion section (outlet part) after the narrow section, the cross-sectional area gradually increases and the flow rate decreases. At this time, the dynamic pressure is converted back into static pressure, so that the air pressure at the outlet is partially restored and close to the inlet air pressure. The pressure loss rate is reduced by 40% to 50%. Compared with the straight-through air inlet, the air flow friction and energy loss are reduced, thereby ensuring the overall pressure of the system, providing favorable protection for network processing, and increasing the network nodes by 20% to 30%.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0022] Example 1
[0023] A main network device base for energy saving and consumption reduction, such as Figure 2-5 As shown, the apparatus comprises a base 1, which is used in conjunction with a main network device body 2. Specifically, the base 1 is provided with a mounting hole 12 for assembling a nozzle, and the mounting hole 12 is provided with an air inlet 11.
[0024] It can be explained here that the base 1 is detachably connected to the main network device body 2 and can be assembled therein by sliding and snapping. The main network device body 2 is provided with a wire guide hole 21 which is adapted to and communicated with the air inlet 11 .
[0025] When in use, the high-pressure gas released by the nozzle is sprayed into the wire guide hole 21 from the air inlet 11, generating a rotating vortex inside the wire guide hole 21, so that the single fibers in the wire bundle passing through the wire guide hole 1 are interwoven with each other, thereby forming a network knot and performing network processing on the wire bundle.
[0026] Furthermore, the air inlet 11 is an hourglass-shaped structure, one end of which is adapted to and connected to the guide wire hole 21, and the other end is connected to the mounting hole 12. The diameter of the air inlet of the hourglass-shaped structure is larger at both ends, and the larger diameter portion is the expansion section, while the diameter in the middle is smaller, and the smaller diameter portion is the narrow section, so that the air inlet forms a Venturi effect.
[0027] When air passes through the narrow section of the hourglass structure, the cross-sectional area decreases and the flow rate accelerates. According to Bernoulli's principle, the increased flow rate causes the static pressure in this area to decrease, but the dynamic pressure to increase. In the expansion section (exit) after the narrow section, the cross-sectional area gradually increases and the flow rate decreases. At this point, the dynamic pressure is converted back into static pressure, partially restoring the air pressure at the outlet, and may even approach or slightly exceed the inlet pressure. This reduces airflow friction and energy loss, thereby maintaining the overall system pressure and providing favorable protection for network processing.
[0028] In this embodiment, the air inlet 11 includes a first conical hole 111 and a second conical hole 112. The expanded end of the first conical hole 111 is connected to the mounting hole 12, and the expanded end of the second conical hole 112 is connected to the guide wire hole 21, so that the contracted ends of the first conical hole 111 and the second conical hole 112 are connected to form an hourglass-shaped structure (i.e., a Venturi tube structure).
[0029] Furthermore, an arc-shaped chamfer 113 is provided at the connection between the first conical hole 111 and the second conical hole 112. The arc-shaped chamfer is used to make the cross-sectional area of the intersection of the first conical hole 111 and the second conical hole 112 gradually change, so as to avoid the airflow diversion caused by the sudden change of the cross-sectional area when the airflow passes through the intersection of the first conical hole 111 and the second conical hole 112, thereby generating vortices and increasing friction loss.
[0030] Furthermore, the diameter of the second tapered hole 112 is three times that of the first tapered hole 111 .
[0031] Furthermore, the base 1 is made of aluminum alloy.
[0032] Example 2
[0033] A main network device base for energy saving and consumption reduction includes a base 1 for use with a main network device body 2. Specifically, the base 1 is provided with a mounting hole 12 for assembling a nozzle, and the mounting hole 12 is provided with two air inlet holes 11.
[0034] It can be explained here that the base 1 is detachably connected to the main network device body 2 and can be assembled by bolt connection. Among them, the main network device body 2 is provided with two wire guide holes 21, and the two air inlet holes 11 correspond to the two wire guide holes 21 and are connected to form two independent air flow ducts.
[0035] Furthermore, one end of the two air inlet holes 11 is connected to a mounting hole 12, so that the two air inlet holes 11 share one air pressure nozzle, which not only saves the use of the nozzle, but also makes the air pressure of the two air inlet holes the same when sharing one nozzle, thereby improving the consistency of the network knot.
[0036] When in use, the high-pressure gas released by the nozzle is sprayed into the wire guide hole 21 from the air inlet 11, generating a rotating vortex inside the wire guide hole 21, so that the single fibers in the wire bundle passing through the wire guide hole 1 are interwoven with each other, thereby forming a network knot and performing network processing on the wire bundle.
[0037] Furthermore, the air inlet 11 is an hourglass-shaped structure, one end of which is adapted to and connected to the guide wire hole 21, and the other end is connected to the mounting hole 12. The diameter of the air inlet of the hourglass-shaped structure is larger at both ends, and the larger diameter portion is the expansion section, while the diameter in the middle is smaller, and the smaller diameter portion is the narrow section, so that the air inlet forms a Venturi effect.
[0038] When air passes through the narrow section of the hourglass structure, the cross-sectional area decreases and the flow rate accelerates. According to Bernoulli's principle, the increased flow rate causes the static pressure in this area to decrease, but the dynamic pressure to increase. In the expansion section (exit) after the narrow section, the cross-sectional area gradually increases and the flow rate decreases. At this point, the dynamic pressure is converted back into static pressure, partially restoring the air pressure at the outlet, and may even approach or slightly exceed the inlet pressure. This reduces airflow friction and energy loss, thereby maintaining the overall system pressure and providing favorable protection for network processing.
[0039] In this embodiment, the air inlet 11 includes a first conical hole 111 and a second conical hole 112. The expanded end of the first conical hole 111 is connected to the mounting hole 12, and the expanded end of the second conical hole 112 is connected to the guide wire hole 21, so that the contracted ends of the first conical hole 111 and the second conical hole 112 are connected to form an hourglass-shaped structure (i.e., a Venturi tube structure).
[0040] Furthermore, an arc-shaped chamfer 113 is provided at the connection between the first conical hole 111 and the second conical hole 112. The arc-shaped chamfer is used to make the cross-sectional area of the intersection of the first conical hole 111 and the second conical hole 112 gradually change, so as to avoid the airflow diversion caused by the sudden change of the cross-sectional area when the airflow passes through the intersection of the first conical hole 111 and the second conical hole 112, thereby generating vortices and increasing friction loss.
[0041] Furthermore, the base 1 is made of aluminum alloy.
[0042] Taking the compressed air pressure requirement of 0.35 MPa as an example, air pressure tests were performed on the conventional straight-through air inlet and the hourglass-shaped air inlet of Example 1 of the present application. Test equipment was prepared: air pressure sensor, differential pressure gauge, anemometer, and data acquisition system.
[0043] The test data is shown in Table 1:
[0044] Ps:0.35MPa=350000Pa.

[0048] According to the comparative experimental data of the hourglass-shaped and straight-through air inlets in Example 1 of the present application with air flow rates of 0.05m3 / s, 0.075m3 / s, and 0.1m3 / s, it can be seen that:

[0050] At 0.05m3 / s, the hourglass-type pressure loss rate of this embodiment 1 is 0.004%, and that of the straight-through type is 0.0063%; at 0.075m3 / s, the hourglass-type pressure loss rate is 0.01%, and that of the straight-through type is 0.017%; at 0.1m3 / s, the hourglass-type pressure loss rate is 0.0186%, and that of the straight-through type is 0.0314%. The hourglass-type pressure loss rate of this embodiment 1 is 40% to 50% lower than that of the straight-through type.
[0051] At 0.05m3 / s, the hourglass-type network nodes of this embodiment 1 are 36 / m, and the straight-through type are 30 / m; at 0.075m3 / s, the hourglass-type network nodes are 57 / m, and the straight-through type are 45 / m; at 0.1m3 / s, the hourglass-type network nodes are 75 / m, and the straight-through type are 55 / m; the hourglass-type network nodes of this embodiment 1 are 20% to 30% higher than the straight-through type.
