Description

Technical Field

[0001] This utility model relates to the technical field of reclaimed water circulating cooling coil assembly, and in particular to a reclaimed water circulating cooling coil assembly. Background Technology

[0002] In the extrusion process, a stable and efficient cooling water circulation system, much like the human circulatory system, is the core hub ensuring the normal operation of the equipment. Its performance directly affects not only the extruder's production efficiency and product quality but also its service life. The cooling water circulation rate, as a key indicator of system efficiency, determines whether the large amount of heat generated during production can be effectively and promptly dissipated.

[0003] However, the commonly used cooling water circulation systems for extruders currently suffer from several drawbacks that urgently need to be addressed. The smooth design of the pipe inner walls, while facilitating manufacturing, easily leads to laminar flow of the cooling water. In this laminar flow state, the cooling water relies solely on conduction for heat transfer, resulting in extremely low heat exchange efficiency between the fluid and the pipe wall, making it difficult to dissipate a significant amount of heat in a timely manner. To maintain cooling effectiveness, the system must frequently replenish with fresh water, which not only drastically reduces the cooling water circulation rate but also causes serious water waste.

[0004] Meanwhile, due to the lack of effective flow turbulence and scale prevention mechanisms, impurities and minerals in the water gradually deposit on the inner walls of the pipes over time. Over time, the scale buildup increases, acting like a thick insulating layer on the pipes, making heat transfer increasingly difficult. Scale also reduces the pipe's inner diameter, increasing fluid resistance and further exacerbating the equipment's operating load. If scale severely clogs the pipes, it will directly lead to equipment failure and shutdown, affecting production schedules and incurring high maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a regenerated water circulating cooling coil assembly. By setting specially distributed baffles in the straight pipes and bends, it effectively solves the problems of low heat exchange efficiency and insufficient cooling water circulation rate of traditional regenerated water circulating cooling coil assemblies. At the same time, it breaks the turbulent state formed by the fluid boundary layer, significantly reduces the risk of scaling, provides a guarantee for the efficient and stable operation of the extruder, and reduces equipment maintenance costs and downtime losses caused by scaling.

[0006] This utility model also provides a reclaimed water circulating cooling coil assembly, comprising: a straight pipe, an elbow detachably connected to the straight pipe, and multiple second-stage baffles fixedly connected to the inner wall of the straight pipe, the second-stage baffles being arranged on the same side and inclined, while being staggered in the vertical direction; multiple first-stage baffles being arranged on the inner wall of the elbow, located on the side away from the straight pipe and distributed in a ring around the axis of the elbow; and a second and a third fixed ring fixedly connected to the inner wall of the straight pipe. Both the fixed ring two and the fixed ring three are provided with rotating grooves, and rotating blocks are engaged in the rotating grooves. A turbulence-inducing net is fixedly connected to the side surface of the rotating blocks. Through the above structure, the fluid boundary layer in the cooling coil assembly can be broken by the turbulence-inducing plates in the straight pipe and the elbow, as well as the turbulence-inducing net in the straight pipe. This promotes the formation of strong turbulence in the regenerated water in the pipe, greatly improves the heat exchange efficiency between the fluid and the pipe wall, thereby increasing the circulation rate of the extruder cooling water and significantly reducing the possibility of scaling and the risk of scaling. At the same time, the turbulence-inducing net can be adjusted.

[0007] According to the regenerated water circulating cooling coil assembly of this utility model, a fixing ring is fixedly connected to the side surface of the straight pipe. Two fixing rings are provided and are located on the upper and lower end side surfaces of the straight pipe, respectively. The above structure makes it easy to determine the position of the fixing ring.

[0008] According to the reclaimed water circulating cooling coil assembly of this utility model, a limiting ring is fixedly connected to the side surface of the elbow. The limiting ring and the fixed ring have the same diameter. The above structure facilitates connection.

[0009] According to the reclaimed water circulating cooling coil assembly of this utility model, a sliding ring is slidably connected to the elbow, and a connecting ring is fixedly connected to the sliding ring. The connecting ring and the fixed ring are threaded together. Through the above structure, it is convenient to fasten the straight pipe and the elbow together.

[0010] According to the regenerated water circulating cooling coil assembly of this utility model, both the straight pipes and elbows are made of titanium alloy, and the above structure facilitates corrosion resistance.

[0011] According to the regenerated water circulating cooling coil assembly of this utility model, the first baffle is a semi-annular structure with a high middle and low sides. This structure facilitates the guidance of fluid to sweep across the outer wall.

[0012] According to the regenerated water circulating cooling coil assembly of this utility model, a flow guide block is fixedly connected to one end of the fixed ring two away from the fixed ring three and one end of the fixed ring three away from the fixed ring two. A through groove is provided on the flow guide block, and the through groove is connected to the rotating groove. Through the above structure, it is convenient to guide the water and also convenient to install the turbulence net.

[0013] According to the regenerated water circulating cooling coil assembly of this utility model, the rotating groove is a quarter ring, and the opening directions of the through grooves on the second and third fixed rings are opposite. The turbulence net has a built-in fixed frame. With the above structure, it is easy to install the turbulence net appropriately according to the water flow direction and prevent the turbulence net from being washed away.

[0014] Beneficial effects:

[0015] 1. The reclaimed water circulating cooling coil assembly of this technical solution, through multiple baffles arranged at an angle on the same side of the inner wall of the straight pipe and vertically staggered, as well as the baffle net inside the straight pipe, can effectively break the fluid boundary layer, promote the formation of strong turbulence in the reclaimed water inside the pipe, and significantly improve the heat exchange efficiency between the fluid and the pipe wall. Its vertical staggered layout can also ensure that the water flow generates sufficient disturbance at different height levels, effectively avoiding the formation of dead zones due to local water flow stagnation, so that the cooling effect is evenly covered throughout the entire coil. Meanwhile, the baffles arranged in a ring around the axis on the inner wall of the elbow away from the straight pipe generate radial turbulence when the water flow turns, forming a three-dimensional turbulence effect with the baffles in the straight pipe, further enhancing fluid mixing and heat transfer, and significantly reducing the possibility of scaling and the risk of scaling. At the same time, the baffle net can be adjusted.

[0016] 2. The regenerated water circulating cooling coil assembly in this technical solution features a detachable elbow design, which greatly facilitates later maintenance and repair, and reduces the difficulty and cost of component replacement. The presence of baffles can also reduce impurity deposition through continuous water flow disturbance, significantly reducing the risk of scaling and effectively extending the service life of the coil, providing a solid guarantee for the stable and efficient operation of the extruder's cooling water circulation system.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5 This utility model embodiment of a reclaimed water circulating cooling coil assembly includes: a straight pipe 1, with an elbow 2 detachably connected to the straight pipe 1. Both the straight pipe 1 and the elbow 2 are made of titanium alloy. A fixing ring 3 is fixedly connected to the side surface of the straight pipe 1. Two fixing rings 3 are provided and are located at the upper and lower end side surfaces of the straight pipe 1, respectively. A limiting ring 8 is fixedly connected to the side surface of the elbow 2. The limiting ring 8 has the same diameter as the fixing ring 3. A sliding ring 4 is slidably connected to the elbow 2. A connecting ring 5 is fixedly connected to the sliding ring 4. The connecting ring 5 is threadedly connected to the fixing ring 3. Multiple baffles 7 are fixedly connected to the inner wall of the straight pipe 1. They are located on the same side and are inclined, while being staggered in the vertical direction. A baffle 6 is provided on the inner wall of the elbow 2. Multiple baffles are arranged on the side away from the straight pipe 1, and are distributed in a ring around the axis of the bend 2. The first baffle 6 is a semi-circular structure with a high middle and low sides. The inner wall of the straight pipe 1 is fixedly connected to the second fixed ring 9 and the third fixed ring 14. The second fixed ring 9 and the third fixed ring 14 are both provided with rotating grooves 10. The rotating block 11 is engaged in the rotating groove 10. The side surface of the rotating block 11 is fixedly connected to the baffle net 12. The end of the second fixed ring 9 away from the third fixed ring 14 and the end of the third fixed ring 14 away from the second fixed ring 9 are both fixedly connected to the guide block 13. The guide block 13 is provided with a through groove, which is connected to the rotating groove. The rotating groove 10 is a quarter ring, and the opening direction of the through groove on the second fixed ring 9 and the third fixed ring 14 is opposite. The baffle net 12 has a built-in fixing frame.

[0027] Specifically, based on the connection method between straight pipe 1 and elbow 2, the water flow direction is determined. Then, the baffle 12 is installed, and the rotating block 11 passes through the rotating groove 10 on the fixed ring 9 or fixed ring 14 to fix the baffle 12. Next, straight pipe 1 and elbow 2 are connected. Utilizing the detachable structure of straight pipe 1 and elbow 2, elbow 2 is aligned with the end of straight pipe 1 to achieve splicing. Then, sliding ring 4 is placed on elbow 2, and pushed to slide along the side surface of elbow 2 until the connecting ring 5 on sliding ring 4 aligns with the fixed ring 3 on straight pipe 1. Then, using a suitable tool, the two are tightened and fixed through the threaded connection between connecting ring 5 and fixed ring 3, completing the stable connection between straight pipe 1 and elbow 2, thus facilitating installation and subsequent maintenance. In actual installation, the combination and number of straight pipe 1 and elbow 2 can be flexibly adjusted according to the specific spatial layout and cooling requirements. By repeating the above connection steps, a coil assembly structure meeting the requirements can be built.

[0028] Connect the assembled reclaimed water circulating cooling coil assembly to the reclaimed water circulation system, ensuring a good seal at the connection points to prevent reclaimed water leakage. Simultaneously, correctly connect the coil assembly to the equipment or system requiring cooling, ensuring that the reclaimed water circulates within the coil assembly along a predetermined path, effectively cooling the target equipment. When water enters straight pipe 1, the staggered baffles 7 on one side of straight pipe 1 disrupt the symmetry of the water flow field, thus enhancing the turbulence effect. When entering elbow 2, the baffles 6 on the outer inner wall of elbow 2 reduce pressure loss, thereby reducing the probability of scaling.

[0029] Working Principle: Reclaimed water flows in from one end of the coil assembly. As the water flows through straight pipe 1, multiple baffles 7 and a baffle net 12 fixedly connected to the inner wall of straight pipe 1 come into play. These baffles 7 are located on the same side and are inclined, staggered in the vertical direction. When the water flows and impacts the baffles 7, its original flow direction and velocity change, forming a complex turbulent state. This turbulence allows for more thorough contact between the reclaimed water and the inner wall of straight pipe 1, increasing the contact area and time between the water and the pipe wall, thereby effectively improving heat transfer efficiency and enabling the reclaimed water to absorb the heat dissipated by the equipment more quickly.

[0030] When water flows through elbow 2, the baffles 6 on the inner wall of elbow 2 begin to function. The baffles 6 are arranged in a ring around the axis of elbow 2, forming a semi-circular structure that is higher in the middle and lower on both sides. During the water's turn, the baffles 6 guide the water flow into a spiral trajectory, further enhancing the turbulence. This spiral flow not only increases the contact opportunity between the water and the inner wall of elbow 2 but also promotes stronger turbulence in the elbow area, ensuring that the reclaimed water can fully exchange heat in the elbow section, evenly transferring the absorbed heat, and guaranteeing a uniform and stable cooling effect for the entire coil assembly. Finally, the reclaimed water, carrying heat, flows out from the other end of the coil assembly, completing the cooling cycle for the equipment.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
