Description

Technical Field

[0001] This utility model relates to the field of heat exchanger sealing joint technology, and in particular to a split-type heat exchanger end cap. Background Technology

[0002] As a core energy-saving device, heat exchangers can transfer heat between various fluids at different temperatures, ensuring that the fluid temperature meets the process requirements and significantly improving energy efficiency. They are widely used in nearly 30 industrial sectors, including HVAC, pressure vessels, wastewater treatment, chemical, petroleum, metallurgy, power, shipbuilding, central heating, refrigeration and air conditioning, machinery, food, and pharmaceuticals, forming a complete and interconnected industrial chain. Data shows that in 2010, the market size of China's heat exchanger industry reached approximately 50 billion yuan, and its importance in industrial production and people's livelihood is becoming increasingly prominent. Among various types of heat exchangers, tubular heat exchangers are widely used due to their stable structure and reliable heat exchange efficiency. They are mainly composed of a shell, tube bundle, tube sheet and end caps. The shell is mostly circular and contains parallel tube bundles. The two ends of the tube bundles are fixed to the tube sheet. The end caps are a key component of the tubular heat exchanger and directly affect the sealing performance, heat exchange effect and overall operational stability of the heat exchanger. To optimize the performance of heat exchanger heads, numerous research and development efforts have been undertaken in related technical fields. For example, Chinese patent CN210862347U discloses a heat exchanger head comprising an outer head with an inlet pipe and an outlet pipe on either side. The inlet pipe has an inlet flange at one end, and the outlet pipe has an outlet flange at the end furthest from the inlet pipe. A connecting flange is bolted to the bottom of the outer head. An inner head is located inside the outer head, with a mounting ring plate fixedly connected to the end of the inner head near the connecting flange. The inner surface of the inlet pipe is coated with an anti-corrosion layer. This technology improves heat exchange efficiency through a double-layer structure design of the inner and outer heads. Simultaneously, the coordinated action of the sealing groove, sealing gasket, first fixing block, long sliding rod, slider, spring, second fixing block, and connecting push rod ensures the sealing gasket is tightly attached to the bottom of the outer head, significantly improving sealing performance and effectively reducing heat loss from the heat exchanger, resulting in good performance and practicality. However, the aforementioned existing technologies still have obvious defects and shortcomings in practical applications. Although the heat exchanger head is equipped with a filter screen structure to filter impurities, the impurities filtered by the filter screen are directly trapped in front of the filter screen. As the usage time increases, the trapped impurities accumulate and gradually cover the entire filter screen, causing it to become clogged. The existing head in this technology lacks an effective slag removal and anti-clogging structure, and cannot quickly clean and collect the accumulated impurities and debris. Once the filter screen becomes clogged, it will not only affect the normal flow of fluid, but also reduce the heat exchange efficiency, and may even cause equipment failure, seriously affecting the stable operation of the heat exchanger. It is evident that the structural design of the existing heat exchanger head still needs further improvement and optimization. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a split-type heat exchanger head, which more precisely solves the problems described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a split heat exchanger head, including an outer head, an inlet pipe fixedly installed on one side of the outer head, an outlet pipe fixedly installed on the other side of the outer head, and a filter mechanism provided at the outer end of the inlet pipe; The filtration mechanism includes a filter box, which is located at the input end of the input pipe. A filter screen is fixedly installed inside the filter box. The filter screen is generally arc-shaped. A cleaning module is movably installed inside the filter box. The cleaning end of the cleaning module is fitted and connected to the inner wall of the filter screen.

[0005] Furthermore, both the input end of the input tube and the output end of the output tube are fixedly mounted with auxiliary mounting flanges, and the filter box is connected to the input end of the input tube through the auxiliary mounting flanges.

[0006] Furthermore, a main mounting flange is fixedly installed at the bottom of the outer end cap, and a sealing gasket is provided on the inner side of the main mounting flange, and a sealing gasket is also provided on the inner side of the auxiliary mounting flange.

[0007] Furthermore, a connecting hopper is fixedly installed at the outer end of the filter box, and an input flange is fixedly installed at the outer end of the connecting hopper.

[0008] Furthermore, the cleaning module includes a rotating shaft rotatably connected to the center of the filter box. Water flow drive plates are fixedly installed on the outer surface of the rotating shaft in a ring-like arrangement at equal intervals. Arc-shaped brush plates are fixedly installed on the outer sides of each water flow drive plate. The outer sides of the arc-shaped brush plates are in contact with the inner side of the filter screen. The filter screen is arc-shaped overall, and its arc surface provides a larger overall filtration area compared to a flat filter screen. Simultaneously, its arc-shaped guide surface prevents impurities from adhering and clogging. Furthermore, the outer sides of the bristles of the arc-shaped brush plates are in contact with the inner side of the filter screen. When fluid enters the filter box, the fluid can flush and drive the water flow drive plates to rotate the rotating shaft. Simultaneously, the arc-shaped brush plates can brush and clean the inner side of the filter screen, preventing clogging.

[0009] Furthermore, a rotating frame is rotatably connected to the top of the filter box, and a load-bearing disc is fixedly installed on the outer side of the rotating frame. The bottom of the rotating frame is connected to the top of the rotating shaft through a coupling. The design of the load-bearing disc and the rotating frame allows the rotating frame and the load-bearing disc to rotate when the water flow drives the water flow drive plate to rotate. The rotation of the load-bearing disc generates additional inertial gravity, which assists in driving the arc-shaped brush plate to rotate. This reduces the resistance of the water flow to the water flow drive plate and improves the smoothness of the water flow.

[0010] Furthermore, an impurity collection hopper is fixedly installed at the bottom of the filter box, and a sealing cap is threadedly connected to the bottom of the impurity collection hopper. The outer surface of the sealing cap is provided with anti-slip textures at equal intervals. The impurity collection hopper is generally conical in shape. An inclined flow guide plate is fixedly installed at the input end of the filter box. The inclined flow guide plate is inclined to one side, which can push the incoming fluid to one side. At this time, the water flow can enter the filter screen box at high speed. The water flow drive plate can be better driven to rotate the shaft through the filter screen box, and the whole can better drive the cleaning module to rotate.

[0011] The beneficial effects of this utility model are: 1. During the application of this technical solution, by setting up a filter mechanism including an arc-shaped filter structure, the fluid filtration area can be expanded during use, reducing the amount of impurities attached per unit area and delaying the clogging trend of the filter structure. At the same time, in conjunction with a water-driven cleaning mechanism, the cleaning components are driven by the impact force of the fluid itself, which can brush and clean the inside of the arc-shaped filter structure in real time, brushing off the attached impurities in time, and preventing impurities from continuously accumulating and covering the filter structure. Thus, the effect of high-efficiency filtration and dynamic anti-clogging is achieved simultaneously, which solves the problem that the filter structure is easily clogged by the accumulation of impurities and affects the flow of fluid in the existing technology. At the same time, no additional power is required to drive the cleaning operation, reducing energy consumption. 2. During the application of this technical solution, by setting a load-bearing structure in the cleaning mechanism, the load-bearing structure rotates synchronously with the cleaning mechanism during use, generating inertial gravity. This inertial gravity helps to enhance the driving effect of the cleaning mechanism, reduces the resistance of water flow impacting the driving components, and allows the cleaning components to clean the filter structure more stably and powerfully, reducing impurity residue and further strengthening the cleaning and anti-clogging capabilities. This achieves the effect of improving the operational stability and cleaning efficiency of the cleaning mechanism. At the same time, by setting up a matching impurity collection and discharge structure, the cleaned impurities can be quickly collected and discharged through simple operation without disassembling the entire filter or cleaning mechanism, avoiding the cleaning process from affecting the normal operation of the equipment. This simplifies the impurity handling process and ensures the continuous and stable operation of the equipment, solving the problems of insufficient driving effect of the cleaning mechanism and inconvenient impurity cleaning and discharge in the prior art.

[0014] 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. Example 1

[0015] A split-type heat exchanger head, wherein an inlet pipe 2 is fixedly installed on one side of the outer head 1, and an outlet pipe 3 is fixedly installed on the other side of the outer head 1, and a filter mechanism 4 is provided at the outer end of the inlet pipe 2; The filtration mechanism 4 includes a filter box 41, which is located at the input end of the input pipe 2. A filter screen 42 is fixedly installed inside the filter box 41. The filter screen 42 is arc-shaped. A cleaning module 43 is movably installed inside the filter box 41. The cleaning end of the cleaning module 43 is attached to the inner wall of the filter screen 42.

[0016] Combination Figures 1-4 As shown, the input end of the input pipe 2 and the output end of the output pipe 3 are both fixedly installed with auxiliary mounting flanges 5. The filter box 41 is connected to the input end of the input pipe 2 through the auxiliary mounting flanges 5. The bottom of the outer end cap 1 is fixedly installed with a main mounting flange 6. The inner side of the main mounting flange 6 is provided with a sealing gasket 7. The inner side of the auxiliary mounting flange 5 is also provided with a sealing gasket 7. The outer end of the filter box 41 is fixedly installed with a connecting bucket 8. The outer end of the connecting bucket 8 is fixedly installed with an input flange 9.

[0017] In the above-described embodiments of this application, during the application of this device, the fluid first enters through the input flange 9 at the outer end of the filter box 41, and flows into the interior of the filter box 41 after being guided by the connecting bucket 8. At this time, the arc-shaped filter screen 42 inside the filter box 41 filters impurities in the fluid, ensuring that the fluid entering the input pipe 2 is clean. When the fluid flows in the filter box 41, it drives the internally movable cleaning module 43 to operate. Since the cleaning end of the cleaning module 43 is in close contact with the inner wall of the filter screen 42, it can clean the impurities attached to the inner wall of the filter screen 42 during operation, avoiding the accumulation of impurities that affect the filtration effect. The filtered clean fluid enters the interior of the outer end cap 1 through the input pipe 2, completes heat exchange, and then... The fluid flows out from the output pipe 3. Throughout the fluid transport process, the auxiliary mounting flange 5 at the input end of the input pipe 2 and the output end of the output pipe 3, and the main mounting flange 6 at the bottom of the outer end cap 1 can achieve stable connection of each component. The sealing gaskets 7 on the inner side of the main mounting flange 6 and the auxiliary mounting flange 5 can effectively prevent fluid leakage. This structural design allows the device to improve filtration efficiency through the arc-shaped filter screen 42 and achieve real-time cleaning of the filter screen 42 with the help of the cleaning module 43. At the same time, the sealing gaskets 7 ensure sealing performance, reduce the risk of fluid leakage, and ensure the overall stable operation of the device. This solves the problems of easy clogging of the filter screen 42 and poor sealing effect in the prior art, and improves the practicality and reliability of the device. Example 2

[0018] Combination Figures 2-5As shown, the cleaning module 43 includes a rotating shaft 431, which is rotatably connected to the center of the filter box 41. Water flow drive plates 432 are fixedly installed on the outer surface of the rotating shaft 431 in a ring at equal intervals. Arc-shaped brush plates 433 are fixedly installed on the outer sides of the water flow drive plates 432. The outer sides of the arc-shaped brush plates 433 are fitted and connected to the inner side of the filter screen 42. The filter screen 42 is arc-shaped overall. Compared to a flat filter screen, its arc surface has a larger overall filtration area. Simultaneously, its arc-shaped guidance can prevent impurities from adhering and clogging the filter screen. The outer side of the bristles of the arc-shaped brush plate 433 is attached to the inner side of the filter screen 42. When fluid enters the filter box 41, the fluid can flush and drive the water flow drive plate 432 to drive the rotating shaft 431 to rotate. While the rotating shaft 431 rotates, its arc-shaped brush plate 433 can brush and clean the inner side of the filter screen 42, which can prevent the filter screen 42 from becoming clogged. The top of the filter box 41 is rotatably connected to the rotating frame 434. The outer side of the rotating frame 434 is fixedly installed with the load plate 435. The bottom of the rotating frame 434 is connected to the rotating shaft 435 through a coupling. The top of filter box 41 is connected to the design of the load plate 435 and the rotating frame 434. When the water flow drives the water flow drive plate 432 to rotate the rotating shaft 431, it can in turn drive the rotating frame 434 and the load plate 435 to rotate. The rotation of the load plate 435 generates additional inertial gravity, which assists in driving the arc-shaped brush plate 433 to rotate. This reduces the resistance of the water flow to the water flow drive plate 432 and improves the smoothness of the water flow. The bottom of the filter box 41 is fixedly installed with an impurity collection hopper 44, and the bottom of the impurity collection hopper 44 is threaded. A sealing button cover 45 is connected, and the outer surface of the sealing button cover 45 is provided with anti-slip texture at equal intervals. The impurity collection hopper 44 is generally conical. An inclined flow guide plate 46 is fixedly installed at the input end inside the filter box 41. The inclined flow guide plate 46 is generally inclined to one side, which can push the incoming fluid to one side. At this time, the water can enter the filter screen 42 box at high speed. Through the filter screen 42 box, the water flow drive plate 432 can be better driven to drive the rotating shaft 431 to rotate, and the whole can better drive the cleaning module 43 to rotate.

[0019] The technical solution described in the above-described embodiments of this application, during the application of this device, through the arrangement of structures such as the inclined flow guide plate 46, the cleaning module 43, the load-bearing plate 435, and the impurity collection hopper 44, ensures that when the fluid enters the filter box 41, it first contacts the inclined flow guide plate 46 at the input end of the filter box 41. The inclined flow guide plate 46 pushes the incoming fluid to one side, allowing the water flow to enter the filter box 41 at high speed, better driving the water flow drive plate 432 of the cleaning module 43. At this time, the high-speed water flow washes away the impurities. The water flow drive plate 432 drives the rotating shaft 431 to rotate within the filter box 41. As the shaft 431 rotates, the arc-shaped brush plates 433 on the outer side of the water flow drive plate 432, arranged in an evenly spaced ring on its outer surface, also rotate. Because the outer side of the arc-shaped brush plates 433 is in close contact with the inner side of the filter screen 42, and the filter screen 42 is generally arc-shaped, the arc-shaped brush plates 433 can clean the inner side of the filter screen 42 by brushing, preventing clogging. Furthermore, the arc-shaped filter screen 42, compared to a flat... The overall filtration area of ​​the filter screen is larger, and the curved guide surface can further reduce the problem of impurity adhesion and clogging. When the water flow drives the water flow drive plate 432 to rotate the rotating shaft 431, the rotating frame 434 connected to the top of the rotating shaft 431 through the coupling also rotates. The load plate 435 on the outside of the rotating frame 434 rotates synchronously. The rotation of the load plate 435 generates additional inertial gravity, which assists in driving the curved brush plate 433 to rotate, reducing the resistance of the water flow to the water flow drive plate 432 and improving the smoothness of the water flow. The impurities brushed off by the curved brush plate 433 will fall into the conical impurity collection hopper 44 at the bottom of the filter box 41 for collection. When it is necessary to clean the impurities, the operator can rotate the sealing button cover 45 threaded at the bottom of the impurity collection hopper 44. The anti-slip texture on the outer surface of the sealing button cover 45 makes it easy to operate. After opening, the impurities can be discharged. The whole process does not require complicated disassembly, which can effectively ensure the continuous and stable operation of the device and solve the problems of easy clogging of the filter screen 42, poor cleaning drive effect and difficulty in cleaning impurities in the existing technology.

[0020] The working principle and advantages of this utility model are as follows: During application, the fluid first enters through the input flange 9 at the outer end of the filter box 41 in this technical solution. The input flange 9 is used to connect to the external supply pipe to ensure stable fluid introduction. After entering, the fluid flows through the connecting bucket 8, which guides and gathers the fluid to prevent it from dispersing and leaking when entering the filter box 41, allowing the fluid to concentrate and enter the filter box 41. When the fluid enters the filter box 41, it first contacts the inclined flow guide plate 46 at the input end inside the filter box 41. The inclined flow guide plate 46 is inclined to one side, which pushes the incoming fluid to one side, allowing the water flow to enter the side area of ​​the filter box 41 at high speed, thereby providing sufficient power for the subsequent operation of the cleaning module 43. The high-speed flowing fluid enters the designated area inside the filter box 41. Afterwards, the fluid is first filtered through filter screen 42. Filter screen 42 is arc-shaped and is used to filter out impurities in the fluid to ensure the cleanliness of the fluid entering the subsequent structure. At the same time, the high-speed fluid impacts the water flow drive plate 432 of the cleaning module 43. The water flow drive plate 432 starts to rotate after being impacted by the fluid. Since the water flow drive plates 432 are arranged in a ring at equal intervals and fixedly installed on the outer surface of the rotating shaft 431, the rotation of the water flow drive plate 432 drives the rotating shaft 431 to rotate synchronously in the middle of the filter box 41. The rotating shaft 431 serves as the rotation core of the cleaning module 43, which further drives the arc-shaped brush plate 433 fixedly installed on its outer surface to rotate. The outer side of the arc-shaped brush plate 433 is attached to the inner side of the filter screen 42. During the rotation, the inner side of the filter screen 42 is brushed and cleaned, and the impurities attached to the filter screen 42 are brushed off. Simultaneously, the rotating frame 434, connected to the top of the rotating shaft 431 via a coupling, also rotates. The load-bearing disk 435, fixedly mounted on the outside of the rotating frame 434, rotates synchronously. The rotation of the load-bearing disk 435 generates additional inertial gravity, which assists in driving the arc-shaped brush plate 433 to rotate, reducing the resistance of the water flow scouring the water flow drive plate 432, allowing the water flow to be smoother. The impurities brushed off by the arc-shaped brush plate 433 fall downwards under the action of gravity and finally fall into the impurity collection hopper 44 at the bottom of the filter box 41. The impurity collection hopper 44 is generally conical in shape and is used to collect impurities in a concentrated manner. To prevent impurities from scattering throughout the filter box 41, the clean fluid filtered by the filter screen 42 flows out of the filter box 41 and into the inlet pipe 2. The inlet end of the inlet pipe 2 is connected to the filter box 41 via the auxiliary mounting flange 5. The auxiliary mounting flange 5 enables a detachable connection between the filter box 41 and the inlet pipe 2, facilitating subsequent maintenance and replacement. The fluid enters the outer head 1 through the inlet pipe 2. The outer head 1 serves as the core housing structure, providing heat exchange space for the fluid and supporting the installation of components such as the inlet pipe 2, the outlet pipe 3, and the main mounting flange 6. The fluid exchanges heat with the tube bundle of the tubular heat exchanger inside the outer head 1. After heat exchange, the fluid flows out from the output pipe 3 on the other side of the outer head 1. The output pipe 3 is used to discharge the fluid after heat exchange inside the outer head 1. The output end of the output pipe 3 is also fixedly installed with a secondary mounting flange 5. The secondary mounting flange 5 is used to connect to the external drain pipe to ensure stable discharge of the fluid after heat exchange. During the entire fluid transportation process, the main mounting flange 6 at the bottom of the outer head 1 is used to connect to the shell of the tubular heat exchanger. The sealing gasket 7 on the inner side of the main mounting flange 6 and the sealing gasket 7 on the inner side of the secondary mounting flange 5 both play a sealing role to prevent leakage of fluid during transportation and heat exchange. When a certain amount of impurities are collected in the impurity collection hopper 44, the operator opens it by rotating the sealing button cover 45 at the bottom of the impurity collection hopper 44. The anti-slip texture is provided at equal intervals on the outer surface of the sealing button cover 45 to increase the friction between the hand and the sealing button cover 45, making it convenient for the operator to rotate. After opening the sealing button cover 45, the operator cleans out the impurities in the collection hopper. After cleaning, the sealing button cover 45 is threaded back to the bottom of the impurity collection hopper 44 to complete the impurity cleaning operation. Throughout the entire process, this technical solution utilizes an arc-shaped filter screen 42, which, compared to a flat filter screen, provides a larger overall filtration area. This reduces the amount of impurities adhering to the filter screen per unit area, slowing down the clogging process. Simultaneously, the arc-shaped brush plate 433 of the cleaning module 43, driven by fluid, continuously brushes and cleans the filter screen 42, promptly removing impurities and preventing their continuous accumulation. This fundamentally solves the problem of easy clogging and lack of anti-clogging structure in the prior art. Furthermore, the impurity collection hopper 44 allows the brushed-off impurities to fall directly into it; operators only need to rotate the sealing knob. Impurities can be cleaned simply by covering the filter with the lid 45, without disassembling the entire filter structure. This significantly shortens the cleaning time and improves cleaning efficiency. The conical impurity collection hopper 44 ensures that impurities are concentrated and collected, preventing them from remaining in the filter box 41. An inclined flow guide plate 46 directs the fluid to one side, allowing the water flow to impact the water flow drive plate 432 at high speed, providing sufficient power for the cleaning module 43 to operate. The inertial gravity generated by the rotation of the load-bearing plate 435 assists in driving the arc-shaped brush plate 433 to rotate, reducing the resistance of the water flow scouring the water flow drive plate 432 and minimizing flow obstruction within the filter box 41, ensuring smooth fluid flow. The fluid flows smoothly through the filter box 41 and inlet pipe 2, avoiding any impact on heat exchange efficiency due to poor flow. Sealing gaskets 7 are installed inside the main mounting flange 6 and the auxiliary mounting flange 5 to ensure the sealing of the connections between the outer end cap 1 and the heat exchanger shell, the filter box 41 and the inlet pipe 2, and the outlet pipe 3 and the external pipeline, respectively. This comprehensively prevents fluid leakage at each connection point, avoiding heat loss and fluid waste caused by leakage. The auxiliary mounting flange 5 connects the inlet pipe 2 to the filter box 41. When components such as the filter screen 42 and cleaning module 43 inside the filter box 41 require maintenance or replacement, only disassembly is needed. The filter box 41 can be removed by removing the mounting flange 5 without disassembling the outer head 1 as a whole, which reduces maintenance difficulty, reduces equipment downtime for maintenance, and ensures continuous and stable operation of the heat exchanger. In addition, the large filtration area of ​​the arc-shaped filter screen 42 can filter more fluid in the same time, and the arc-shaped guiding effect can prevent impurities from accumulating locally on the surface of the filter screen 42, so that the filtration performance of the filter screen 42 can be evenly exerted. Compared with the flat filter screen, the overall filtration efficiency is higher, ensuring that the fluid entering the outer head 1 always maintains a high level of cleanliness and preventing impurities from entering the outer head 1 and affecting the heat exchange effect or causing wear on the internal components of the equipment. During the application of this device, the fixed installation of each structure can be selected by bolt installation, welding installation, screw installation or some flexible snap-fit ​​installation. If a detachable design is required, bolt or screw installation can be selected. If a stable installation is required, welding installation can be selected. The specific requirements can be flexibly selected according to the application requirements.

[0021] During the application of this device, the fixed installation of each structure can be selected by bolt installation, welding installation, screw installation or some flexible snap-fit ​​installation. If a detachable design is required, bolt or screw installation can be selected. If a stable installation is required, welding installation can be selected. Specific requirements can be flexibly selected according to application requirements. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0022] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
