Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a high-efficiency heat exchange jacket head with a spiral guide groove. Background Technology

[0002] Traditional jacketed heads are used in chemical and pharmaceutical fields, but due to the easy short-circuiting and leakage of fluid, low flow velocity and uneven distribution, the heat exchange efficiency and uniformity are poor. There are also problems such as medium impacting the container wall, large pressure drop and the need for thicker cylinder walls for large equipment, which make it difficult to meet the requirements of high-efficiency heat exchange and energy saving. Therefore, a structure with spiral guide grooves was developed to optimize performance.

[0003] In existing technologies, heat exchange equipment used in chemical, pharmaceutical, and food processing industries often employs a composite cylindrical head structure with an inner and outer jacket to achieve fluid heat exchange. However, existing jacket structures have significant drawbacks: firstly, fluid flow within the jacket tends to form short-circuit flow, resulting in weak turbulence and a thick boundary layer, leading to a low heat transfer coefficient and insufficient heat exchange efficiency to meet production demands, thus increasing energy consumption and operating costs; secondly, particulate impurities in the fluid tend to deposit on the inner wall of the jacket, further deteriorating heat transfer performance and potentially clogging jacket channels, affecting normal equipment operation and making cleaning and maintenance difficult; and thirdly, if a fixed flow guiding structure is installed in a traditional jacket, it cannot adapt to flow fluctuations, easily leading to flow instability, further restricting heat exchange performance. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency heat exchange jacket head with a spiral flow guide groove, which can solve the problems of low heat exchange efficiency, unstable flow, and impurity blockage in existing heat exchange systems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat exchange jacket head with a spiral flow guide groove, comprising a head body, a heat exchange mechanism movably connected to the inner side of the head body, a filter assembly movably connected to the inner side of the heat exchange mechanism, the heat exchange mechanism comprising a jacket body, a spiral flow guide channel being formed on the inner side of the jacket body, a plurality of fixing rings being fixedly connected to the inner side of the spiral flow guide channel, and the plurality of fixing rings being evenly arranged on the inner side of the spiral flow guide channel, and a flow limiting component being movably connected to the inner side of the fixing rings.

[0006] Preferably, the filter assembly includes several support rings, all of which are fixedly connected to the inner side of the spiral guide channel and are evenly arranged on the inner side of the spiral guide channel, located on the opposite side of every two fixed rings.

[0007] Preferably, telescopic columns are fixedly connected to both sides of the inner side of the fixed ring, and a sieve plate is fixedly connected to one side of the two sets of telescopic columns facing each other.

[0008] Preferably, a helical spring is fitted onto the outer side of the telescopic column.

[0009] Preferably, the current limiting component includes a current limiting rotating plate, which is rotatably connected to the inner side of the fixed ring. Both sides of the current limiting rotating plate are fitted with torsion springs, one end of each torsion spring is fixedly connected to both sides of the current limiting rotating plate, and the other end of each torsion spring is fixedly connected to both sides of the inner side of the fixed ring.

[0010] Preferably, a flow-limiting port is provided on the inner side of the flow-limiting plate.

[0011] Preferably, the front side of the spiral guide channel is fixedly connected to a liquid inlet, and the liquid inlet is located at the top of the front side of the end cap body.

[0012] Preferably, the front side of the spiral guide channel is fixedly connected to a liquid outlet, and the liquid outlet is located at the bottom of the front side of the end cap body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This application solves the problems of low heat transfer coefficient, insufficient heat transfer efficiency, and increased energy consumption and operating costs caused by the formation of short-circuit flow, weak turbulence intensity, and large boundary layer thickness in existing heat exchange equipment by setting an annular spiral flow channel inside the jacket body and guiding the flow from top to bottom. At the same time, fixed rings are set at equal intervals in the spiral flow channel, and the inner side of the ring is rotatably connected to a flow-limiting plate with a torsion spring. The opening can be automatically adjusted according to the flow rate and reset by the force dissipation of the torsion spring. This solves the problem that the traditional fixed flow guiding structure cannot adapt to flow fluctuations and is prone to flow instability. Ultimately, it achieves the beneficial effects of improving heat transfer capacity and ensuring stable heat transfer performance. 2. This application, by setting up a filter assembly, utilizes internally hollowed-out support rings between every two fixed rings. The inner walls of these rings are fitted with arrayed telescopic columns, each with an outer spiral spring. The telescopic ends are fixedly connected to and limited by a sieve plate. When the heat exchange liquid impacts the sieve plate, it presses down the telescopic columns and springs on the non-impact side. Upon rebound, it acts on the impact side, causing the sieve plate to vibrate and filter. This intercepts particulate impurities in the fluid, preventing impurities from depositing on the inner wall of the jacket body and clogging the jacket channels, thus avoiding deterioration of heat transfer efficiency. Simultaneously, it reduces the frequency of cleaning and maintenance, solving the problems related to impurity deposition in existing equipment. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 The present invention provides the following technical solution: A high-efficiency heat exchange jacket head with a spiral flow guide groove includes a head body 1, a heat exchange mechanism 2 movably connected to the inner side of the head body 1, a filter assembly 3 movably connected to the inner side of the heat exchange mechanism 2, the heat exchange mechanism 2 includes a jacket body 21, a spiral flow guide channel 22 is opened on the inner side of the jacket body 21, several fixing rings 23 are fixedly connected to the inner side of the spiral flow guide channel 22, and the several fixing rings 23 are evenly arranged on the inner side of the spiral flow guide channel 22, and a flow limiting assembly 24 is movably connected to the inner side of the fixing rings 23.

[0018] In this embodiment: instead of setting a traditional fixed flow guiding structure, a spiral flow guiding channel 22 in the shape of a spiral flow guiding groove is set in a ring inside the jacket and can guide the flow from top to bottom. The spiral flow guiding channel 22 can significantly extend the heat exchange path and can also fully cover the head body 1 to increase the heat exchange capacity. At the same time, in order to prevent flow fluctuations and flow instability, the flow limiting component 24 can avoid the situation where the heat exchange performance decreases due to flow instability.

[0019] Specifically, such as Figure 5 As shown, the filter assembly 3 includes several support rings 31, which are all fixedly connected to the inner side of the spiral guide channel 22 and are evenly arranged on the inner side of the spiral guide channel 22, and are located on the opposite side of every two fixed rings 23.

[0020] Specifically, such as Figure 5 As shown, telescopic columns 32 are fixedly connected to both sides of the inner side of the fixed ring 23, and a sieve plate 34 is fixedly connected to the opposite side of the two sets of telescopic columns 32.

[0021] Specifically, such as Figure 5 As shown, a helical spring 33 is sleeved on the outer side of the telescopic column 32.

[0022] In this embodiment: a set of support rings 31 is provided between every two fixed rings 23. The support rings 31 are hollow inside, and there are arrays of telescopic columns 32 on both sides of their inner walls, with spiral springs 33 on their outer sides. The telescopic ends of the telescopic columns 32 are fixedly connected to both sides of the sieve plate 34, while the sieve plate 34 is restricted to the inside of the support rings 31. When the heat exchange liquid passes through the sieve plate 34, it will impact the sieve plate 34, causing the sieve plate 34 to press the telescopic columns 32 and their outer spiral springs 33 on the non-impact side. When the sieve plate 34 rebounds, it will act on the telescopic columns 32 and their outer spiral springs 33 on the impact side. In this way, the sieve plate 34 forms a vibrating filter state under the impact of the liquid, thereby achieving impurity interception, preventing impurities from accumulating and clogging the sieve plate 34, and reducing the number of cleaning times.

[0023] Specifically, such as Figure 3 , Figure 4 As shown, the current limiting component 24 includes a current limiting rotating plate 2401, which is rotatably connected to the inner side of the fixed ring 23. Both sides of the current limiting rotating plate 2401 are fitted with torsion springs 2402. One end of each torsion spring 2402 is fixedly connected to the two sides of the current limiting rotating plate 2401, and the other end of each torsion spring 2402 is fixedly connected to the two sides of the inner side of the fixed ring 23.

[0024] Specifically, such as Figure 3 , Figure 4 As shown, a flow-limiting port 2403 is provided on the inner side of the flow-limiting plate 2401.

[0025] In this embodiment: multiple sets of fixed rings 23 are provided at equal intervals in the spiral flow guiding channel 22. Each fixed ring 23 is rotatably connected to a flow-limiting plate 2401. Torsion springs 2402 are sleeved on both sides of the rotating shaft of the flow-limiting plate 2401. When the heat exchange liquid flow rate is large but the flow velocity is uniform, it will continue to flow through the fixed-size flow-limiting port 2403 opened in the center of the flow-limiting plate 2401. When the flow rate increases and the flow velocity becomes faster, causing the flow-limiting port 2403 to be unable to accommodate such a large flow rate, the liquid impacts the flow-limiting plate 2401 to make it rotate and expand the flow opening. At this time, the flow velocity has been greatly reduced, and the impact force can be continuously reduced by the rebound force of the torsion spring 2402. After the flow rate and flow velocity tend to stabilize, the flow-limiting plate 2401 will reset under the action of the torsion spring 2402. In this way, the heat exchange performance is avoided due to unstable flow.

[0026] Specifically, such as Figure 1 , Figure 2 As shown, the front side of the spiral guide channel 22 is fixedly connected to the liquid inlet 4, and the liquid inlet 4 is located at the top of the front side of the head body 1.

[0027] Specifically, such as Figure 1 , Figure 2 As shown, a liquid outlet 5 is fixedly connected to the front side of the spiral guide channel 22, and the liquid outlet 5 is located at the bottom of the front side of the head body 1.

[0028] In this embodiment, the heat exchange fluid is supplied and discharged through the inlet 4 and the outlet 5.

[0029] Working Principle: In heat exchange equipment used in chemical, pharmaceutical, and food processing industries, the main body often adopts a composite cylindrical head structure 1 with inner and outer layers, and a jacket body 21 is set between the inner and outer layers to achieve fluid heat exchange. However, in the existing jacket body 21 structure, when the fluid flows inside the jacket body 21, it is easy to form short-circuit flow, with weak turbulence intensity and large boundary layer thickness, resulting in low heat transfer coefficient and heat exchange efficiency that is difficult to meet production needs, increasing equipment energy consumption and operating costs. Moreover, if a fixed flow guiding structure is set in the traditional jacket body 21, it cannot adapt to flow fluctuations and is prone to flow instability, further restricting heat exchange performance. To avoid the above situations, the traditional fixed flow guiding structure is no longer set, but a ring-shaped distribution is set instead. Inside the jacket, a spiral guide channel 22, shaped like a spiral channel, is formed from top to bottom. This spiral guide channel 22 greatly extends the heat exchange path and fully covers the head body 1 to increase the heat exchange capacity. To prevent flow fluctuations and instability, multiple sets of fixed rings 23 are evenly spaced inside the spiral guide channel 22. Each fixed ring 23 is rotatably connected to a flow-limiting plate 2401 on its inner side. Torsion springs 2402 are sleeved on the rotating shafts on both sides of the flow-limiting plate 2401. When the heat exchange liquid flow rate is large and the flow velocity is uniform, the liquid can be continuously transferred through the fixed-size flow-limiting port 2403 opened in the center of the flow-limiting plate 2401. When the flow rate increases and the flow velocity becomes faster, the flow-limiting port 2403... 03. Unable to achieve flow limit due to insufficient load, the liquid needs to impact the flow-limiting rotating plate 2401 to increase the flow opening and achieve transfer. At this point, the flow velocity is significantly limited, and continuous force dissipation is achieved through the rotational force of the torsion spring 2402. Once the flow velocity stabilizes, the flow-limiting rotating plate 2401 can reset under the action of the torsion spring 2402, thus avoiding the decrease in heat transfer performance caused by unstable flow. Secondly, to prevent particulate impurities in the fluid from easily depositing on the inner wall of the jacket body 21, which not only further deteriorates the heat transfer effect but may also block the jacket channel, affecting the normal operation of the equipment and causing difficulties in cleaning and maintenance, a set of support rings 31 is provided between every two fixed rings 23. The support ring 31 is hollow inside, and telescopic columns 32 with outer spiral springs 33 arranged in an array on both inner walls. The telescopic ends of the telescopic columns 32 are fixedly connected to both sides of the sieve plate 34, keeping the sieve plate 34 confined to the inside of the support ring 31. When the heat exchange liquid passes through the sieve plate 34, it will impact it, causing it to press the telescopic columns 32 on the non-impact side and the outer spiral springs 33. When it rebounds, it will also act on the telescopic columns 32 on the impact side and the outer spiral springs 33, thus forming a vibrating filter screen under the impact of the liquid. This achieves the interception of impurities and prevents impurities from accumulating and clogging the sieve plate 34, reducing the number of cleaning times. In summary, this achieves the optimization of the high-efficiency heat exchange jacket head with spiral guide grooves.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
