Description

Technical Field

[0001] This utility model relates to the technical field of wide-flow-channel flushing water heat exchangers, and in particular to a direct-flow wide-flow-channel flushing water plate heat exchanger. Background Technology

[0002] A heat exchanger is a device used to transfer heat from one fluid to another. It is widely used in many fields such as industry, construction, and automobiles to achieve efficient heat transfer and utilization. Meanwhile, the existing direct-flow wide-channel slag flushing water plate heat exchanger is a special type of plate heat exchanger, mainly used for heat exchange processes of slag flushing water and other fluids containing solid particles or high viscosity.

[0003] A search revealed Chinese Patent Publication No. CN221666709U, which discloses a wide-channel plate heat exchanger, comprising a rear clamping plate, a front clamping plate, and a heating plate. A supporting slide rail is fixedly installed on the front of the rear clamping plate near its upper edge. A connecting slider is fixedly installed on the heating plate, and a limiting strip is provided above the connecting slider. A threaded hole is formed at the center of the connecting slider, and a connecting through hole is formed at the center of the limiting strip. A fixing bolt is installed in the connecting through hole, and the fixing bolt is threaded into the threaded hole. A limiting groove is formed on the front of the front clamping plate near its upper edge, and the limiting groove slides in conjunction with the supporting slide rail. The limiting strip and the connecting slider form a T-shaped slider, which is engaged inside the supporting slide rail. Therefore, after the fixing column is removed, the T-shaped slider supports the heating plate, allowing it to hang below the supporting slide rail and preventing the heating plate from falling directly.

[0004] Although the aforementioned patent has been approved, the T-shaped slider is locked inside the support rail, so that after the fixing column is removed, the T-shaped slider will support the heating plate hanging below the support rail, preventing the heating plate from falling directly. However, in use, multiple threaded rods are usually used to rotate, and the rotation of the threaded rods pushes the extrusion plate to move, thereby applying pressure to the conduction plate. Since each threaded rod needs to be adjusted individually, a lot of time is required each time the conduction plate is installed and maintained, reducing work efficiency. To address this issue, a direct-flow wide-channel slag flushing water plate heat exchanger is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a direct-flow wide-channel slag flushing water plate heat exchanger, which aims to improve the problem that some existing direct-flow wide-channel slag flushing water plate heat exchangers cannot quickly extrude and position the extrusion plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A direct-flow wide-channel slag-flushing plate heat exchanger includes a support frame, a pushing mechanism on one side of the support frame, multiple guide rods fixedly connected to both sides of the support frame, multiple conductive plates slidably connected inside the support frame, and a cleaning mechanism on the outside of the guide rods. The pushing mechanism includes two pillars, which are fixedly connected to the outside of the support frame. Two rotating columns are rotatably connected to the outside of the two pillars. A support rod is fixedly connected to the outside of the rotating columns. A connecting rod is rotatably connected to the outside of the support rod. A pushing frame is slidably connected inside the support frame. A locking assembly is provided at the top of the support frame. A rotating assembly is provided on the outside of the pushing frame, near the connecting rod. By adopting the above technical solution: by pulling the connecting rod, relative rotation is generated between the support rod and the connecting rod, which in turn drives the rotating column to rotate outside the support column. The connecting rod applies pressure to the push frame through the rotating component, pushing the push frame to slide along the inside of the support frame, squeezing the conduction plate to make it fit tightly. This achieves rapid squeezing and fixing and precise release of the conduction plate, which significantly improves heat exchange efficiency and ease of operation. At the same time, it is simple to operate and easy to maintain, which can effectively extend the service life of the equipment and reduce operating costs.

[0007] Preferably, the locking assembly includes a support rod, the outer two sides of which are fixedly connected to the top of the support frame, a sliding block is slidably connected to the outer side of the support rod, a bolt is threadedly connected to the top center of the sliding block, a sliding groove is provided on the top of the support rod, a connecting plate is slidably connected to the inside of the sliding groove, and the outer side of the connecting plate, i.e. the side closest to the support rod, is threadedly connected to the top of the connecting plate. By adopting the above technical solution, the sliding block and bolts are used to quickly fix and release the push frame. The operation is simple and convenient, and it can effectively prevent the push frame from shifting during operation, ensuring the stable operation of the heat exchanger. At the same time, the design of the support rod and sliding groove provides a stable sliding path for the sliding block.

[0008] Preferably, the rotating assembly includes multiple brackets, one outer side of each bracket is fixedly connected to the outer rear side of the push frame, a connecting column is fixedly connected inside each bracket, and the other outer side of the connecting rod is rotatably connected to the outside of the connecting column. By adopting the above technical solution: multiple brackets are fixed to the outer rear side of the push frame, and the connecting column inside the brackets provides a stable rotation fulcrum for the connecting rod. When the connecting rod rotates under the drive of the support rod, its other end rotates outside the connecting column, thereby transmitting power to the push frame.

[0009] Preferably, the push frame is internally slidably connected to the outside of the plurality of guide rods, and the outside of the support rod and the connecting rod are located between the plurality of guide rods; By adopting the above technical solution, the sliding of the push frame is precisely guided by the guide rod, ensuring that the push frame remains stable during movement and avoiding deviation caused by vibration or external force.

[0010] Preferably, the cleaning mechanism includes a limiting ring, the limiting ring being externally coupled to the outside of one of the guide rods, and a connecting rod being fixedly connected to the outside of the limiting ring, i.e., the side closest to the conductive plate; By adopting the above technical solution, the limiting ring is coupled to the guide rod, and the limiting ring can slide up and down and rotate outside the guide rod, so that the coupling connection between the limiting ring and the guide rod provides stable support and flexible movement capability for the cleaning mechanism.

[0011] Preferably, a cleaning brush is fixedly connected to the outside of the connecting rod, i.e., the side closest to the conductive plate, and two slots are provided on the outside of the connecting rod, i.e., the side away from the conductive plate; By adopting the above technical solution: the cleaning brush is set to act directly on the surface of the conduction plate, which can efficiently remove dirt and ensure the cleanliness of the conduction plate, thereby improving the heat exchange efficiency. The slot design provides a stable limiting function for the connecting rod, so that it remains in a fixed position when it is not cleaned.

[0012] Preferably, a retaining ring is fixedly connected to the outside of the connecting rod, i.e., the side near the retaining groove, and the outside of the retaining groove is slidably connected to the outside of the guide rod; By adopting the above technical solution, the retaining ring is fixed on the side of the connecting rod near the retaining groove and cooperates with the retaining groove, which further enhances the fixing ability of the connecting rod on the guide rod, so that the cleaning mechanism can remain stable when not in use and avoid loosening or displacement caused by external force.

[0013] Preferably, the limiting ring is designed to be hollow, so that the limiting ring can slide up and down and left and right outside one of the guide rods, and can rotate outside the guide rod; By adopting the above technical solution, the limiting ring can move flexibly on the guide rod, thereby driving the connecting rod and cleaning brush connected to it to move to the appropriate position to clean the transmission plate.

[0014] In summary, this utility model has the following beneficial effects: 1. In this utility model, by pulling the connecting rod, the support rod and the connecting rod rotate relative to each other, and a V-shaped push is gradually formed between the support rod and the connecting rod. The connecting rod applies pressure to the push frame through the support of the connecting column, causing the push frame to slide along the inside of the support frame towards the direction of the conduction plate, thereby squeezing multiple conduction plates and making them fit tightly together. This achieves rapid squeezing and fixing of the conduction plates and precise release, improving the operating efficiency and ease of operation of the heat exchanger.

[0015] 2. In this utility model, the sliding and rotation of the limiting ring enables the cleaning brush to move and position flexibly, accurately cleaning the surface of the conduction plate and effectively preventing dust accumulation, thereby significantly improving heat exchange efficiency. The dual limiting design of the slot and the retaining ring enhances the stability and reliability of the cleaning mechanism. Attached Figure Description

[0018] Reference Figure 1 , Figure 2 and Figure 4The present invention provides an embodiment of a direct-flow wide-channel slag flushing water plate heat exchanger, comprising a support frame 1, which is designed to provide support capacity. A pushing mechanism 2 is provided on one side of the support frame 1. Multiple guide rods 3 are fixedly connected to the two sides of the support frame 1, which are designed to provide lateral support capacity. The guide rods are arranged in groups of three, with two groups located on the two sides of the support frame 1. Multiple conduction plates 4 are slidably connected inside the support frame 1, which are designed to provide heat exchange capacity. When the slag flushing water flows in the wide channel, heat exchange occurs through the conduction plates 4. A cleaning mechanism 5 is provided on the outside of the guide rods 3. The driving mechanism 2 includes two support columns 21, designed to provide support and be vertically fixed to the rear exterior of the support frame 1. The two support columns 21 are externally fixedly connected to one side of the support frame 1. Two rotating columns 22 are rotatably connected to the exterior of the two support columns 21, designed to provide rotational capability. The support columns 21 allow the rotating columns 22 to rotate outside the support columns 21. A support rod 23 is fixedly connected to the exterior of the rotating columns 22, designed to provide support and connection capability. The rotation of the rotating columns 22 outside the support columns 21 allows the support rod 23 to rotate with the rotating columns 22. A connecting rod is rotatably connected to the exterior of the support rod 23. The connecting rod 24 can rotate on the other side outside the support rod 23 while the support rod 23 rotates. The push frame 25 is slidably connected inside the support frame 1. By sliding inside the support frame 1, the push frame 25 can squeeze multiple conduction plates 4, so that different numbers of conduction plates 4 can be pressed together for effective heat exchange. The top of the support frame 1 is provided with a locking component 26. The outside of the push frame 25, that is, the side close to the connecting rod 24, is provided with a rotating component 27. The inside of the push frame 25 is slidably connected to the outside of multiple guide rods 3, and the outside of the support rod 23 and the connecting rod 24 are located between multiple guide rods 3. Specifically, after placing the conduction plate 4 inside the support frame 1, the connecting rod 24 is pulled, causing the support rod 23 and the connecting rod 24 to rotate. This allows the support rod 23 to rotate to the outside of the rotating column 22, enabling it to rotate outside the support column 21. This creates a V-shaped push between the support rod 23 and the connecting rod 24. The connecting rod 24 can apply pressure to the push frame 25 through the rotating component 27, pushing the push frame 25 towards the conduction plate 4. This compresses the conduction plate 4, improving heat exchange efficiency. The design of the push frame 25 allows for quick movement of the push frame 25, saving installation time.

[0019] Reference Figure 1 , Figure 2 and Figure 5The locking assembly 26 includes a support rod 261, designed to provide support. The outer sides of the support rod 261 are fixedly connected to the top of the support frame 1. A sliding block 262 is slidably connected to the outside of the support rod 261, designed to provide sliding capability. This allows the sliding block 262 to slide outside the support rod 261 when the pusher 25 moves inside the support frame 1, providing guiding capability. A bolt 263 is threaded to the top center of the sliding block 262, designed to provide locking capability. A sliding groove 265 is formed at the top of the support rod 261, designed to provide sliding space. A connecting plate 264 is slidably connected inside the sliding groove 265, designed to provide sliding capability, allowing the connecting plate 264 to slide smoothly within the sliding groove 265. The pusher 25 is then secured inside the connecting plate 264 by bolts 263, thus limiting and fixing it. The outer side of the connecting plate 264, near the support rod 261, is threaded to the top of the connecting plate 264. The rotating assembly 27 includes multiple brackets 271, designed to provide support. One side of the multiple brackets 271 is fixedly connected to the outer rear side of the pusher 25. A connecting column 272 is fixedly connected inside the brackets 271, designed to provide support. The other side of the connecting rod 24 is rotatably connected to the outside of the connecting column 272. Through the rotation of the connecting rod 24 and the support rod 23, the connecting rod 24 rotates outside the connecting column 272, pushing the pusher 25 and maintaining stability when the pusher 25 is pushed. Specifically, after the bracket 271 is supported on the rear side of the push frame 25, the connecting column 272 can be well supported. Then, the rotation between the support rod 23 and the connecting rod 24 can smoothly push the push frame 25 towards the transmission plate 4. Then, the sliding block 262 slides on the outside of the support rod 261, which can guide the push frame 25. After the push frame 25 has moved, the bolt 263 is threaded on the outside of the connecting plate 264, which can lock the connecting plate 264 and the sliding block 262 at the top of the sliding block 262, thereby limiting the position of the push frame 25.

[0020] Reference Figure 1 and Figure 6The cleaning mechanism 5 includes a limiting ring 51, which is hollow in design, allowing it to slide up and down and left and right outside one of the guide rods 3, and to rotate outside the guide rod 3. The limiting ring 51 is externally coupled to the outside of one of the guide rods 3. A connecting rod 52 is fixedly connected to the outside of the limiting ring 51, near the side of the transmission plate 4, providing support. The rotation and sliding of the limiting ring 51 causes the connecting rod 52 to move accordingly. A cleaning brush 53 is fixedly connected to the outside of the connecting rod 52, near the side of the transmission plate 4, providing cleaning capability and enabling cleaning of the surface of the transmission plate 4. For cleaning, two slots 54 are provided on the outer side of the connecting rod 52, that is, the side away from the transmission plate 4. The design provides a locking capability, so that after it is locked on the top of the transmission plate 4 through the inner wall of the limiting ring 51, the slots 54 can be locked on the outside of the guide rod 3 on the same side by rotating the limiting ring 51 again, thereby limiting the connecting rod 52. A retaining ring 55 is fixedly connected to the outer side of the connecting rod 52, that is, the side near the slots 54. The design provides a locking capability. After it is locked on the outside of the guide rod 3 through the slots 54, the retaining ring 55 can also be locked on the outside of the guide rod 3, increasing the locking capability of the connecting rod 52. The outer side of the slots 54 is slidably connected to the outside of the guide rod 3. Specifically, after the heat transfer of the conduction plate 4 is completed, the push frame 25 moves backward, causing gaps to form between each conduction plate 4. Then, the limiting ring 51 moves upward, causing the slot 54 and the retaining ring 55 to leave the outside of the guide rod 3. The rotation of the limiting ring 51 can drive the connecting rod 52 to slide on the surface of the conduction plate 4. Then, the cleaning brush 53 can clean the surface of the conduction plate 4. Its design can prevent the accumulation of dust from reducing the efficiency of heat exchange.

[0021] Working Principle: During operation, the conductive plate 4 is first placed inside the support frame 1, at which point it is in its initial ready-to-work state. Then, by pulling the connecting rod 24, relative rotation occurs between the support rod 23 and the connecting rod 24. This rotation is transmitted to the outside of the rotating column 22, causing rotation on the outside of the support column 21. A V-shaped push gradually forms between the support rod 23 and the connecting rod 24. The connecting rod 24, supported by the connecting column 272, applies pressure to the pushing frame 25, causing it to slide along the inside of the support frame 1 towards the conductive plate 4. This compresses the multiple conductive plates 4, ensuring they fit tightly together and guaranteeing effective heat exchange. Once the pusher frame 25 is moved to the appropriate position, the sliding block 262 slides outside the support rod 261. Simultaneously, the bolt 263 at the top center of the sliding block 262 is threaded into the connecting plate 264. By rotating the bolt 263, the connecting plate 264 and the sliding block 262 are secured, thus limiting and fixing the pusher frame 25 to prevent displacement during operation. At this time, the flushing water flows in the wide channel formed inside the support frame 1, exchanging heat through the conduction plate 4 to cool the flushing water. During heat exchange, after the heat exchange is completed, the bolt 263 is loosened, allowing the sliding block 262 and support rod 261 to return to their sliding state. The pusher frame 25 can then slide in the opposite direction, releasing the pressure on the conduction plate 4, facilitating maintenance or replacement of the conduction plate 4. This design allows for quick installation, pressure fixing, and disassembly of the conduction plate 4, improving the efficiency and convenience of the heat exchanger. When the heat exchange is complete and the conduction plates 4 need cleaning, the cleaning mechanism 5 begins operation. First, the pusher 25 moves backward, creating a gap between the conduction plates 4. At this time, the limiting ring 51 slides upward on the guide rod 3, causing the slot 54 and retaining ring 55 on the connecting rod 52 to disengage from the guide rod 3, releasing the constraint on the connecting rod 52. Next, by rotating the limiting ring 51, the connecting rod 52 and the cleaning brush 53 are moved towards the surface of the conduction plates 4. After the cleaning brush 53 adheres to the surface of the conduction plates 4, the limiting ring 51 continues to slide and rotate left and right on the guide rod 3, causing the cleaning brush 53 to thoroughly clean the conduction plates 4, preventing dust accumulation from affecting heat exchange efficiency. After cleaning, the limiting ring 51 is rotated in the opposite direction, causing the slot 54 and retaining ring 55 to re-engage on the guide rod 3, returning the connecting rod 52 to its initial position, completing the cleaning process, and awaiting the next cleaning cycle.
