Description

Technical Field

[0001] The utility model relates to the technical field of chilled water systems, and particularly relates to a sleeve for a chilled water pipeline system. Background Art

[0002] At present, in some workshops, more than one chilled water pipeline system is used. Additionally, another chilled water pipeline system is added according to the production equipment processes in the workshop. During production, if one of the chilled water pipeline systems fails, it will affect the production requirements corresponding to this chilled water pipeline system. Therefore, the chilled water pipeline system required by the workshop is connected to the chilled water pipeline system required by the production equipment processes, that is, the two are connected through a newly added pipeline. After a failure occurs in one of the chilled water pipeline systems, the other chilled water pipeline system can supply the failed chilled water pipeline system through the newly added pipeline to maintain normal production. Among them, when a failure occurs in one of the chilled water pipeline systems, when the other chilled water pipeline system passes through the newly added pipeline, since a newly added pipeline is branched, the chilled water in the other chilled water pipeline system is shared. When this part of the chilled water passes through the pipeline, if the surrounding environmental temperature is relatively high, such as in hot weather, the chilled water will exchange heat with the external high-temperature environment through the pipeline, causing the chilled water to absorb heat and increase its own temperature. As a result, the heat exchange effect that the chilled water pipeline system can achieve during the final production use is reduced, affecting normal production. Content of the Utility Model

[0003] In order to solve the problem that the chilled water exchanges heat with the surrounding high-temperature environment when passing through the pipeline, resulting in an increase in the temperature of the chilled water and affecting the production efficiency of the workshop or production equipment processes, the utility model provides a sleeve for a chilled water pipeline system, which can reduce the heat exchange efficiency between the chilled water and the surrounding high-temperature environment when passing through the pipeline, and avoid the chilled water from heating up too fast and affecting the final production efficiency of the workshop or production equipment processes.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A sleeve for a chilled water pipeline system is provided, including:

[0006] An inner pipe for transporting chilled water;

[0007] An outer pipe sleeved on the inner pipe, with an annular pipe sleeved on the outer pipe. A plurality of connecting rods are circumferentially arranged on the outer wall of the outer pipe, and the free end of each connecting rod is connected to the inner wall of the annular pipe;

[0008] The first baffle plates: A plurality of first baffle plates are inclinedly arranged on the inner wall of the annular pipe. The plurality of first baffle plates are distributed along the length direction of the annular pipe, and the connection positions of each first baffle plate and the annular pipe are on the same straight line. There is a first gap between each first baffle plate and the outer wall of the outer pipe.

[0009] In some embodiments of the present utility model, through holes corresponding to each first baffle plate are formed on the side wall of the annular pipe. A rotating rod is rotatably connected to each through hole. Each rotating rod is connected to each first baffle plate. There is a second gap between each first baffle plate and the inner wall of the annular pipe. A limiting ring is provided on each rotating rod.

[0010] In some embodiments of the present utility model, a fixing seat is provided at the free end of each rotating rod. The same connecting rod is hinged on each fixing seat. A dial is provided on the outer wall of one of the rotating rods.

[0011] In some embodiments of the present utility model, a support rod is further provided on the inner wall of the annular pipe. An inclined second baffle plate is provided at the free end of the support rod.

[0012] In some embodiments of the present utility model, the annular pipe includes a first annular pipe and a second annular pipe. A first fixing block is provided on the outer wall of the first annular pipe. A second fixing block that fits with the first fixing block is provided on the outer wall of the second annular pipe. Communicating screw holes are formed on both the first fixing block and the second fixing block. A fastening bolt is threadedly connected to the screw hole.

[0013] In some embodiments of the present utility model, leakage holes are formed on the side wall of the annular pipe.

[0014] In some embodiments of the present utility model, a filter screen is provided on the inner wall of the annular pipe.

[0015] In some embodiments of the present utility model, the inner diameter of the annular pipe gradually decreases and then gradually increases along its own length direction, and the inner diameters at both ends of the outer pipe are the same.

[0016] The beneficial effects of the present utility model are:

[0017] The inner pipe is the chilled water pipeline system used to connect the workshop and the production equipment process. Chilled water flows in the inner pipe, and the high-temperature external environment will affect the temperature of the chilled water in the inner pipe through the outer pipe. Therefore, an outer pipe is sleeved on the inner pipe, and a ring pipe is arranged on the outer wall of the outer pipe through a connecting rod. When the external air passes through the ring pipe, it can be blocked by the baffle on the ring pipe. In summer, the air humidity is relatively high and contains moisture, and the inside of the ring pipe is close to the relatively low-temperature inner pipe, thus forming a temperature difference. Coupled with the fact that the baffle is arranged on the ring pipe, the air blocked by the baffle can form water droplets on the baffle. These water droplets will move on the baffle due to their own gravity. During the moving process, the water droplets will be dried and evaporated by the subsequent blowing-in wind, and can take away the heat transferred from the ring pipe to the baffle. In addition, before evaporation, the water droplets will continue to move and fall onto the outer pipe. Since the outer wall surface of the outer pipe is an arc surface, the water droplets dripping onto the outer pipe will also continue to move, and when the subsequent wind blows in, they will evaporate and take away the heat of the outer pipe, preventing the excessive heat on the outer pipe from affecting the temperature of the chilled water in the inner pipe.

To simplify the disclosure of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model.

[0031] The embodiments of the utility model will be described in detail below with reference to the drawings. Embodiment

[0032] As Figure 1 shown, this embodiment provides a sleeve for a chilled water pipeline system, including:

[0033] Inner pipe 1, which is used for conveying chilled water;

[0034] Outer pipe 2, which is sleeved on inner pipe 1. An annular pipe 3 is sleeved on outer pipe 2. A plurality of connecting rods 4 are circumferentially arranged on the outer wall of outer pipe 2, and the free end of each connecting rod 4 is connected to the inner wall of annular pipe 3;

[0035] The first baffle 30, a plurality of first baffles 30 are inclined on the inner wall of the annular pipe 3, the plurality of first baffles 30 are distributed along the length direction of the annular pipe 3, and the connection part of each first baffle 30 and the annular pipe 3 is located on the same straight line. There is a first gap between each first baffle 30 and the outer wall of the outer pipe 2.

[0036] The inner pipe 1 is used for conveying chilled water, and the outer pipe 2 is sleeved on the inner pipe 1. The outer wall of the outer pipe 2 is connected to the annular pipe 3 through a plurality of connecting rods 4, which plays a supporting effect on the annular pipe 3. Each first baffle 30 is inclined on the inner wall of the annular pipe 3. The inclination angle of each first baffle 30 may be different, and the inclination direction may also be different, as long as the wind entering the annular pipe 3 can be blocked by the first baffle 30 and condensed into water droplets. There is a first gap between the end of the first baffle 30 facing the outer pipe 2 and the outer pipe 2, that is, it does not contact the outer pipe 2, so as to prevent the heat on the annular pipe 3 from being transferred to the outer pipe 2 through the first baffle 30 and affecting the temperature of the chilled water in the inner pipe 1.

[0037] During use, air enters the inside of the annular pipe 3. The air flowing in the annular pipe 3 will contact the first baffle 30 provided on the inner wall of the annular pipe 3. After the air contacts the first baffle 30, since the air contains moisture, water droplets will condense on the first baffle 30. During the movement of the water droplets on the first baffle 30, due to the temperature on the first baffle 30 and the air circulation in the pipe, the water droplets will evaporate and dry, taking away the heat on the first baffle 30. If the water droplets are not completely evaporated and dried during the movement on the first baffle 30, they will fall onto the outer pipe 2 and continue to move on the outer wall of the outer pipe 2 until the water droplets evaporate and dry, taking away the heat on the outer pipe 2 and preventing the heat on the outer pipe 2 from being transferred to the inner pipe 1 and affecting the temperature of the chilled water in the inner pipe 1.

[0038] Furthermore, as Figure 2 shown, through holes 31 corresponding to each first baffle 30 are formed on the side wall of the annular pipe 3. A rotating rod 32 is rotatably connected to each through hole 31. Each rotating rod 32 is connected to each first baffle 30. There is a second gap between each first baffle 30 and the inner wall of the annular pipe 3. A limiting ring is provided on each rotating rod 32.

[0039] The through holes 31 are provided on the top side wall of the ring tube 3. The intervals between each through hole 31 may be equal or unequal. The multiple through holes 31 are all on the same straight line and are distributed along the length direction of the ring tube 3. It is worth noting that the distribution along the length direction of the ring tube 3 may also be arranged at a certain angle to the central axis of the ring tube 3, as long as the first baffle 30 can be rotated by rotating the rotating rod 32 on the through hole 31. The limiting ring is arranged on the outer part of the rotating rod 32 located on the ring tube 3, and is used to limit the rotating rod 32. The second gap between each first baffle 30 and the inner wall of the ring tube 3 enables the first baffle 30 to rotate without restriction.

[0040] When in use, the rotation angle of the first baffle 30 can be adjusted by rotating the rotating rod 32. The larger the rotation angle of the rotating rod 32, the larger the contact area between the first baffle 30 and the circulating air, the more water droplets can condense on the first baffle 30, and the more heat can be taken away by evaporation. The specific rotation angle of the rotating rod 32 can be adjusted according to actual needs.

[0041] Further, such as Figure 3 and 4 As shown, a fixing seat 320 is provided on the free end of each rotating rod 32 , and a connecting rod 321 is hinged on each fixing seat 320 . A dial wheel 33 is provided on the outer wall of one of the rotating rods 32 .

[0042] A fixing seat 320 is provided on the end of the rotating rod 32 located outside the annular tube 3, that is, the end of the rotating rod 32 away from the outer tube 2, and each fixing seat 320 is hinged to the connecting rod 321, so that the connecting rod 321 can rotate on the fixing seat 320 along the rotation direction of the rotating rod 32. When one of the rotating rods 32 rotates, the rotation of the other rotating rods 32 can be adjusted at the same time, so as to reduce the need to rotate each rotating rod 32. In addition, in this embodiment, there are more than one group of rotating rods 32 distributed along the length direction of the annular tube 3, that is, there are multiple structures composed of multiple rotating rods 32 distributed along the length direction of the annular tube 3, which increases the number of first baffles 30 in the annular tube 3, and can more completely utilize the air entering the annular tube 3, so that the air can more easily condense water droplets on the first baffle 30. Among them, since the rotating rod 32 can rotate the first baffle 30, so that the first baffle 30 is tilted, when the first baffle 30 contacts the circulating air entering the ring tube 3, it can change the flow direction of the air by its own tilt angle. After the air flow direction is changed, the air will be blown to the first baffle 30 at another location in the ring tube 3 to condense water droplets, and more heat on the ring tube 3 and the outer tube 2 can be taken away by evaporation of water droplets. The dial wheel 33 is set on the outer wall of the rotating rod 32, so that the rotating rod 32 can be rotated by manually dialing the dial wheel 33.

[0043] Further, such asFigure 5 and Figure 7 As shown in Figure 7 , a support rod 34 is further provided on the inner wall of the annular pipe 3, and an inclined second baffle 35 is provided at the free end of the support rod 34.

[0044] In this embodiment, the number of the support rods 34 is multiple, which are distributed along the length direction of the annular pipe 3, and the support rods 34 are staggered on the inner wall of the annular pipe 3. The support rods 34 are arranged on the inner wall of the annular pipe 3 near the bottom position. In this embodiment, the support rods 34 are arranged along the radial direction of the outer pipe 2, and the second baffle 35 is inclined at the free end of the support rod 34. The inclined second baffle 35 is used to catch the water droplets sliding down from the outer wall of the outer pipe 2, so that the water droplets can continue to move on the second baffle 35. During the moving process, the wind entering the annular pipe 3 can also dry the water droplets on the second baffle 35. And because the support rods 34 are arranged on the annular pipe 3, the temperature on the annular pipe 3 is transmitted to the second baffle 35 through the support rods 34, so that the water droplets can evaporate on the second baffle 35 and take away the heat. It should be noted that the inclined surface of the second baffle 35 should be inclined towards the pipe orifice of the annular pipe 3, so that the wind coming in from the pipe orifice can blow onto the second baffle 35.

[0045] During use, the wind blows into the inside of the annular pipe 3 from the pipe orifice of the annular pipe 3. The first baffle 30 in the annular pipe 3 will hinder the normal flow of air. The flowing air will form water droplets on the first baffle 30 due to the temperature difference. The water droplets will move towards the bottom of the annular pipe 3 on the first baffle 30 under the influence of their own gravity. During the moving process, the water droplets will gradually evaporate under the influence of the air flowing in the annular pipe 3, and carry away the heat on the first baffle 30; if the water droplets moving on the first baffle 30 are not completely evaporated, some water droplets will fall onto the outer wall of the outer pipe 2. The water droplets on the outer wall of the outer pipe 2 will also be dried under the air flowing in the annular pipe 3, achieving the effect of taking away the heat on the outer pipe 2; if the water droplets on the outer wall of the outer pipe 2 are still not completely evaporated during the moving process, then the remaining water droplets will drip from the outer wall of the outer pipe 2 onto the second baffle 35 located at the bottom of the annular pipe 3. The second baffle 35 can catch the unevaporated water droplets. The water droplets falling onto the second baffle 35 will continue to move on the inclined second baffle 35. During the moving process of the water droplets, they will still evaporate under the air flowing inside the annular pipe 3 and take away the heat on the second baffle 35, preventing the annular pipe 3 from affecting the internal environmental temperature of the annular pipe 3 under the influence of the external high temperature, and preventing the internal environmental temperature from having a greater impact on the temperature of the chilled water in the inner pipe 1.

[0046] Furthermore, as Figure 6As shown in the figure, the annular pipe 3 includes a first annular pipe 36 and a second annular pipe 37. A first fixing block 360 is provided on the outer wall of the first annular pipe 36, and a second fixing block 370 that fits with the first fixing block 360 is provided on the outer wall of the second annular pipe 37. Communication screw holes 38 are provided on both the first fixing block 360 and the second fixing block 370, and a fastening bolt 39 is threadedly connected to the screw hole 38.

[0047] The annular pipe 3 is divided into the first annular pipe 36 and the second annular pipe 37, and the first annular pipe 36 and the second annular pipe 37 can form a complete annular pipe 3. After the first fixing block 360 on the outer wall of the first annular pipe 36 corresponds to the second fixing block 370 on the outer wall of the second annular pipe 37, the first annular pipe 36 and the second annular pipe 37 are connected by the cooperation of the fastening bolt 39 and the screw hole 38. When disassembling, first loosen the fastening bolt 39. After the fastening bolt 39 and the screw hole 38 are disengaged, the first annular pipe 36 and the second annular pipe 37 can be disassembled. The disassembled first annular pipe 36 and second annular pipe 37 are convenient for cleaning their inner walls and are also convenient for storage and transportation. It should be noted that there are two first fixing blocks 360 on the outer wall of the first annular pipe 36, which are respectively located at both ends in the circumferential direction of the first annular pipe 36. There are also two second fixing blocks 370 on the outer wall of the second annular pipe 37, which are respectively located at both ends in the circumferential direction of the second annular pipe 37. And during the tightening process of the fastening bolt 39, to enhance the connection stability between the first annular pipe 36 and the second annular pipe 37, a fastening nut 390 can be threadedly connected to the fastening bolt 39 to achieve the effect of enhancing stability.

[0048] During use, by adjusting the tightness of the fastening bolt 39, the installation and disassembly between the first annular pipe 36 and the second annular pipe 37 can be realized. On the one hand, it is convenient to clean the inner walls of the first annular pipe 36 and the second annular pipe 37, preventing the accumulated dust and sundries from affecting the heat dissipation efficiency of the first annular pipe 36 and the second annular pipe 37; on the other hand, after the first annular pipe 36 and the second annular pipe 37 are disassembled, it is convenient for loading and transportation, reducing the space occupied during transportation.

[0049] Furthermore, as Figure 6 shown in the figure, a leakage hole 371 is provided on the side wall of the annular pipe 3.

[0050] The leakage hole 371 is provided on the side wall at the bottom of the annular pipe 3, that is, the place where the water droplets finally move and accumulate. By providing the leakage hole 371 here, the internal space of the annular pipe 3 is connected to the outside world, which can prevent the accumulation of moisture in the annular pipe 3 and reduce the heat dissipation efficiency of the annular pipe 3.

[0051] Furthermore, as Figure 8 shown in the figure, a filter screen 5 is provided on the inner wall of the annular pipe 3.

[0052] A filter screen 5 is provided on the inner wall of the annular pipe 3, and the filter screen 5 is provided near the pipe orifices at both ends of the annular pipe 3. The connection method between the filter screen 5 and the inner wall of the annular pipe 3 is bonding, or other detachable connection methods, such as bolt connection, etc. The filter screen 5 is an air filter screen 5, which is used to filter dust or adsorb moisture in the air. When it is used to filter dust in the air, it is to prevent dust from accumulating on the inner wall of the annular pipe 3, resulting in a reduction in heat dissipation efficiency; when it is used to adsorb moisture in the air, it is to prevent the outer wall surface of the outer pipe 2 from icing in winter. It can be specifically selected and used according to the actual environmental conditions.

[0053] Further, as Figure 8 shown, the inner diameter of the annular pipe 3 gradually decreases and then gradually increases along its own length direction, and the inner diameters at both ends of the outer pipe 2 are the same.

[0054] When moving from the pipe orifices at both ends of the annular pipe 3 towards its interior, its inner diameter will gradually decrease, but will not shrink to zero, and when the inner diameter is the smallest, its size is one-half of the diameters at both ends of the annular pipe 3.

[0055] During use, since the internal diameter of the annular pipe 3 changes, that is, a structure with wide ends and narrow middle, when the wind blows into the interior of the annular pipe 3, as the inner diameter of the annular pipe 3 decreases, the speed of the wind passing through the annular pipe 3 will increase. Based on Bernoulli's principle, as the inner diameter of the annular pipe 3 gradually decreases, the flow rate of the gas increases, thus achieving the effect of enhancing the gas flowability and being able to blow away the heat from the interior of the annular pipe 3 faster.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Without conflict, the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
