Description

Technical Field

[0001] The utility model relates to the technical field of special equipment for cable manufacturing, in particular to quick-drying equipment for a cable drying system and a drying system thereof. Background Art

[0002] In the cable drying system, quick drying equipment such as a quick drying box is usually used. Taking the quick drying box as an example, it usually includes a channel that allows the cable to pass through, and high-speed gas is introduced into the channel through a gas transmission device, and then the gas dries the surface of the cable.

[0003] However, in the process of using such quick-drying boxes, in order to fit the outer surface of the cable for better drying effect, the size of the channel is usually small. When high-speed gas is ejected from a small channel or nozzle at high speed and then enters a larger, unobstructed space, turbulence and vortexes will be generated due to the sudden change in flow rate and pressure. On the one hand, the turbulence and vortexes generated by the gas will cause huge noise, which may easily cause damage to the health of workers in long-term operation; on the other hand, turbulence and vortexes will cause huge vibrations, which will not only affect quick-drying equipment such as quick-drying boxes to affect their service life, but also act on cables, causing potential damage to cables, especially optical cables, electrical cables and other cables with high precision requirements. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a quick-drying device for a cable drying system, which can effectively reduce the jet noise generated by gas and the incidental vibration, and reduce the damage caused to the cable itself and related construction personnel in the cable drying process.

[0005] The utility model is realized through the following technical solutions.

[0006] A quick-drying device for a cable drying system, characterized in that it comprises: a quick-drying channel connected to an air inlet and adapted to the cable to be dried, specifically, the shape of the cross section of the inner diameter of the quick-drying channel is the same as the cross section of the cable, but the size of the inner diameter is larger than the cable, but the gas flowing out of the air inlet can be guided to perform laminar flow along the radial direction of the quick-drying channel after colliding with the cable to complete the drying work;

[0007] Diversion channels are provided at both ends of the quick-drying channel;

[0008] A guide channel, arranged on one end of the diversion channel away from the quick-drying channel;

[0009] A plurality of deceleration channels, one end of each of which is connected to the diversion channel, and the other end of each of which is connected to the peripheral space of the quick-drying device;

[0010] The cross section of the diversion channel is larger than that of the quick-drying channel and / or the guide channel. The deceleration channel may have a plurality of obstacles or a plurality of sections of channels arranged in a circuitous manner, so as to consume the kinetic energy of the gas during its flow and ultimately reduce the flow rate of the gas.

[0011] In the utility model, the air inlet is directly connected to the quick-drying channel, so the gas flow rate in the quick-drying channel is the fastest, and the moisture on the cable can be quickly dried. Then, the gas flows from both ends of the quick-drying channel into the diversion channel.

[0012] Among them, since the cross-sectional area of ​​the diversion channel is larger than that of the quick-drying channel and the guide channel, when the gas just enters, the flow rate remains basically unchanged, and the flow rate of the gas will be greatly slowed down. Then, turbulence and other phenomena will be caused in the diversion channel, and the flow direction of the gas will begin to change.

[0013] After the flow direction of the gas changes, some of the gas can flow into the deceleration channel connected to the diversion channel. Although the remaining gas will still flow into the guide channel, the gas flow rate is greatly reduced after being diverted by the deceleration channel, and its flow rate in the guide channel will be significantly lower than that in the quick-drying channel. Therefore, when the gas is discharged through the guide channel, the noise generated is reduced, and the vibration of the gas to the cable is effectively reduced.

[0014] The gas flowing into the deceleration channel will have its overall flow rate slowed down after passing through the deceleration channel structure, and will generate less noise when it is finally discharged from the quick-drying device. In addition, compared with the opening on the guide channel, the outlet of the deceleration channel is farther away from the cable, and the gas vibration generated by the gas injection is difficult to act on the cable.

[0015] As a further improvement of the present invention, a connecting port is formed at the connection between the deceleration channel and the diversion channel, and the connecting port is evenly distributed on the inner wall of the diversion channel, so as to introduce part of the gas from the diversion channel into the deceleration channel as much as possible without causing the gas to still flow out from the guiding channel.

[0016] As a further improvement of the present invention, the deceleration channel includes a plurality of deceleration branch channels, and the plurality of deceleration branch channels are arranged in a circuitous manner. Specifically, the circuitous arrangement refers to that the plurality of deceleration channels are connected end to end, but are in a non-linear state, so that the gas needs to make multiple turns when flowing in the pipeline, and the flow path of the gas is relatively tortuous. When flowing in such a channel, the gas loses a lot of kinetic energy and its flow rate gradually slows down because the gas hits the wall multiple times and then turns, thus achieving a deceleration effect in the present invention.

[0017] As a further improvement of the utility model, the deceleration branch channel includes a plurality of first deceleration paths arranged in parallel with each other, and two adjacent first deceleration paths are separated by a partition block; being parallel with each other means that the central axes of the two adjacent first deceleration paths are parallel with each other;

[0018] The deceleration branch channel also includes a plurality of second deceleration paths, which cut off the partition block and the first deceleration path. Under this structure, part of the gas is prone to further turn and collide with other airflows during the circulation process, which generally reduces the flow rate of the gas.

[0019] As a further improvement of the present invention, the first deceleration track is a curved channel.

[0020] As a further improvement of the utility model, a water diversion groove is provided at the bottom of the diversion channel, and the water diversion groove is connected to the water diversion pipe, which is used to divert the accumulated water out of the quick-drying device. During the drying process, the gas easily carries water to flow, but when it flows into the diversion channel, the flow rate of the gas is greatly reduced, and the water carried therein is easy to gather, and eventually falls to the bottom of the diversion channel or hangs on the inner wall of the diversion channel. Part of the water hanging on the inner wall may slide to the bottom after being affected by factors such as gas impact and gravity, and the water diversion groove at the bottom will guide all the water that falls at the bottom of the diversion channel to flow to the location of the water diversion pipe. And finally, the accumulated water is guided to flow out of the quick-drying device through the water diversion pipe.

[0021] As a further improvement of the utility model, the quick-drying device includes a main body and an upper cover, the main body and the upper cover divide the quick-drying channel, the diversion channel and the guide channel, one side of the upper cover is movably connected to the main body so that the upper cover can rotate around the movable connection, and a fixing part is provided on the side of the main body and the upper cover away from the movable connection, and when the upper cover completely covers the main body, the fixing part is used to fix the relative position between the upper cover and the main body.

[0022] A cable surface drying system, characterized in that it comprises a box, a quick-drying device arranged in the box, an air transmission device connected to the quick-drying device, and a cable channel passing through the box, wherein the quick-drying device is any one of the quick-drying devices for the cable drying system mentioned above.

[0023] As a further improvement of the present invention, a sound-absorbing component is arranged on the inner wall of the box body, and the sound-absorbing component can be a sound-absorbing board filled with sound-absorbing material, a wall sound-absorbing structure with a large number of holes on the surface, and the like.

[0024] As a further improvement of the utility model, the box body includes at least two quick-drying devices, and the quick-drying channels, the diversion channels and the guide channels in the quick-drying devices have different sizes, so that different quick-drying devices are used to dry cables of different sizes;

[0025] A displacement device is arranged at the bottom of a plurality of the quick-drying devices to move the quick-drying devices in a non-working state.

[0026] When the quick-drying channel, diversion channel and guide channel of the quick-drying device can wrap the moving path of the cable, that is, the cable can pass through the above channels without any obstacles, the quick-drying device is in working state, and the channel in the quick-drying device in working state is adapted to the size of the current cable. The rest of the quick-drying devices in non-working state need to be moved by the displacement device, and the displacement device can move the quick-drying device in any direction, and it only needs to ensure that the quick-drying device in non-working state is not placed on the moving path of the cable and does not cause any obstruction to the movement of the cable.

[0027] The beneficial effects of the utility model include:

[0028] (1) Reduce the gas jet noise and gas vibration associated with the jet noise generated at the entrance and exit of the cable during the use of the quick-drying equipment, which, on the one hand, reduces the damage to the hearing and other health of the workers, and on the other hand, reduces the potential damage that the gas vibration may cause to the cable;

[0029] (2) By optimizing the overall structure of the blow-drying system, the noise generated by the blow-drying system as a whole can be further reduced; and by equipping the system with quick-drying equipment of different specifications to adapt to the drying of cables of different sizes, the versatility of the blow-drying system can be enhanced.

DETAILED DESCRIPTION

[0037] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0038] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0039] In this embodiment, Figure 1 As shown, in order to display a smaller-sized quick-drying device A, the adopted appearance is box-shaped, but the overall appearance and size of the quick-drying device A do not affect the protection scope of the claims of the utility model.

[0040] Embodiment 1:

[0041] A quick-drying device for a cable drying system mainly comprises a quick-drying channel 1, a diversion channel 2, a guide channel 3 and a deceleration channel 4. Figure 2 As shown, the quick-drying channel 1, the diversion channel 2 and the guide channel 3 are interconnected and are all located on the moving path of the cable, that is, the cable can pass through the quick-drying device A through the above three channels.

[0042] The quick-drying channel 1 is placed at the center of the quick-drying device A, and both ends thereof are connected to the diversion channel 2, and the end of the diversion channel 2 away from the quick-drying channel 1 is connected to the guide channel 3. That is, after the cable enters the quick-drying device A, it passes through "guide channel 3-diversion channel 2-quick-drying channel 1-diversion channel 2-guide channel 3" in sequence.

[0043] Among them, the quick-drying channel 1 is adapted to the size of the cable to be dried, the cross-sectional shape of the inner diameter of the quick-drying channel 1 is the same as the cross-sectional shape of the cable, and the inner diameter of the quick-drying channel 1 is larger than the cable to avoid obstruction to the movement of the cable; but after the gas flowing out of the air inlet collides with the cable to complete the drying work, the gas is guided to flow in a laminar manner along the radial direction of the quick-drying channel 1, that is, the distance from the inner wall of the quick-drying channel 1 to the outer surface of the cable is small and the distance is equal everywhere.

[0044] The cross-sectional area of ​​the diversion channel 2 is larger than that of the quick-drying channel 1 and the guide channel 3, and the diversion channel 2 is connected to a plurality of deceleration channels 4, such as Figure 2 As shown, there is a connecting port 201 on the inner wall of the diversion channel 2 which is connected to the deceleration channel 4 .

[0045] The deceleration channel 4 is mainly used to reduce the flow rate of the gas flowing therethrough, which is mainly achieved by absorbing or consuming the kinetic energy of the gas. For example, a circuitous pipeline can be used to force the flow path of the gas to become tortuous and consume the kinetic energy of the gas during circulation; or multiple obstacles can be set in the flow path to cause the gas to collide with the obstacles and reduce its speed.

[0046] In this embodiment, the air inlet is used to introduce high-speed gas, and the air inlet is connected to the quick-drying channel 1. After the high-speed gas is input from the air inlet, the gas collides with the cable and blows away the moisture on it. Since the size of the quick-drying channel 1 is small and its inner wall is close to the outer surface of the cable, the quick-drying channel 1 will guide the gas to move along the radial direction of the quick-drying channel 1 and enter the diversion channel 2. Since the cross-section of the diversion channel 2 is larger than the quick-drying channel 1 and the guide channel 3, the gas flow rate in the diversion channel 2 is reduced while keeping the gas flow rate unchanged. At this time, turbulence and the like are likely to occur in the diversion channel 2, resulting in variable gas flow direction. After the gas flow direction changes, it is easy for part of the gas to flow into the deceleration channel 4. This type of gas flowing into the deceleration channel 4 is discharged to the outside of the quick-drying device A after the kinetic energy decays, and its flow rate is reduced, which in turn reduces the noise and vibration generated.

[0047] The rest is the gas flowing into the deceleration channel 4. The overall gas flow rate is reduced, and the flow rate of the gas is also lower than that of the gas in the quick-drying channel 1. Finally, when the gas flows out of the quick-drying equipment A, the noise and vibration generated will also be reduced.

[0048] Preferably, if Figure 2 As shown, a connecting port 201 is formed at the connection between the deceleration channel 4 and the diversion channel 2 , and the connecting ports 201 are evenly distributed on the inner wall of the diversion channel 2 so as to guide more gas with variable flow directions to flow into the deceleration channel 4 .

[0049] Preferably, the deceleration channel 4 includes a plurality of deceleration branch channels 401, and the plurality of deceleration branch channels 401 are arranged in a circuitous manner. Figure 3 What is shown is a layout of a circuitous deceleration branch channel 401. The circuitous layout of the channel can drive the path of the gas flowing therethrough to become more tortuous. In this embodiment, the gas can turn multiple times during circulation, thereby causing its kinetic energy to be consumed and the flow speed to be slowed down.

[0050] Preferably, if Figure 4As shown, the deceleration branch channel 401 includes a plurality of first deceleration paths 401-1 arranged in parallel with each other, and two adjacent first deceleration paths 401-1 are separated by a partition block 401-2; the deceleration branch channel 401 also includes a plurality of second deceleration paths 401-3, and the second deceleration paths 401-3 cut off the partition block 401-2 and the first deceleration paths 401-1. Under this structure, the gas flowing therethrough can be guided to have a more turbulent flow, guide the collision between the airflows, consume the overall kinetic energy of the gas, and achieve a deceleration effect.

[0051] Preferably, if Figure 4 As shown, the first deceleration track 401 - 1 is a curved channel, and its central axis is a curve.

[0052] Preferably, if Figure 2 As shown, a water guide groove 202 is provided at the bottom of the diversion channel 2. When the high-speed gas in the quick-drying channel 1 dries the moisture on the cable, the airflow usually still carries moisture. After entering the diversion channel 2, the flow rate of the gas is slowed down, and the moisture may re-condense to form water droplets, etc. Eventually, some of the water droplets will fall to the bottom of the diversion channel 2 under the influence of gravity.

[0053] In this embodiment, a water diversion groove 202 is provided at the bottom of the diversion channel 2, which can guide the water at the bottom to flow into the water diversion groove 202. Further preferably, in the bottom of the water diversion groove 202, the end close to the quick-drying channel 1 is relatively high and the end close to the guide channel 3 is relatively low, which can further collect part of the water blown by the gas. The water diversion groove 202 is connected to the water diversion pipe, and finally the accumulated water is led out of the quick-drying device A.

[0054] Preferably, if Figure 1 As shown, the quick-drying device A comprises a main body A01 and an upper cover A02, which together divide the quick-drying channel 1, the diversion channel 2 and the guide channel 3. One side of the upper cover A02 is movably connected to the main body A01 through a hinge structure, so that the upper cover A02 can rotate around the hinge structure. A fixing member A03 is provided on one side of the main body A01 and the upper cover A02 away from the movable connection.

[0055] The fixing member A03 used in this embodiment is a push-type locking structure, which includes a locking tongue arranged in the upper cover A02 and a locking port arranged on the main body A01. When the upper cover A02 is rotated so that the locking tongue falls into the locking port, the locking tongue will be engaged, and the quick-drying device A is in a closed and locked state; then, the locking tongue can be disengaged by pressing a button on the main body A01, and the quick-drying device A is in an unlocked state.

[0056] Embodiment 2:

[0057] A cable surface drying system, such as Figure 5 As shown, it includes a box body B, a quick-drying device A arranged in the box body B, an air transmission device C connected to the quick-drying device A, and a cable channel D passing through the box body B, wherein the quick-drying device A is any quick-drying device for a cable drying system described in Example 1.

[0058] Preferably, a sound-absorbing component B01 is provided on the inner wall of the box body B. In this embodiment, a sound-absorbing pad made of sound-absorbing cotton is used, and a plurality of raised structures are evenly distributed on the surface thereof to form an overall wavy contact surface, which can absorb a large amount of noise.

[0059] Preferably, if Figure 5 As shown, the box B contains two quick-drying devices A. When the quick-drying device A passes through the cable, the quick-drying device A is performing the drying work of the cable, and it is in a working state. In this embodiment, the quick-drying channel 1, the diversion channel 2, and the guide channel 3 of the quick-drying device A in the working state are smaller than the quick-drying device A in the non-working state. Therefore, in this embodiment, the quick-drying device A in the working state is suitable for drying cables of smaller size.

[0060] In this embodiment, a displacement device, i.e., a lifting rod, is provided at the bottom of the two quick-drying devices A, which is used to lower the quick-drying devices A in a non-working state so that they are not in the moving path of the cable, thereby not hindering the movement of the cable.

[0061] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
