Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, specifically to a structurally improved high-efficiency wide-channel plate heat exchanger. Background Technology

[0002] Wide-channel plate heat exchangers are heat exchange devices specifically designed for heating or cooling fluids containing solid particles, fibrous suspensions, and viscous fluids. Their unique plate structure and wide-gap channel design allow the medium to flow unrestricted across the heat exchange surface of the plates without clogging or retention, effectively preventing the deposition and blockage of solid particles, suspended matter, fibers, and viscous substances.

[0003] However, existing wide-channel plate heat exchangers are generally fixed with bolts during use. When maintenance is required, workers need to use tools to remove the bolts, which makes disassembly very cumbersome and reduces maintenance efficiency. To address the above problems, the inventors have proposed a structurally improved high-efficiency wide-channel plate heat exchanger. Utility Model Content

[0004] To address the problem that wide-channel plate heat exchangers are typically fixed with bolts during use, requiring workers to use tools to remove the bolts during maintenance, which is cumbersome, this utility model aims to provide a structurally improved, high-efficiency wide-channel plate heat exchanger.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: A structurally improved high-efficiency wide-channel plate heat exchanger includes a base plate, a heat exchanger body is provided above the base plate, a mounting plate is welded to the bottom surface of the heat exchanger body, the mounting plate is movably inserted into the base plate, a threaded tube is fixedly provided inside the base plate, a threaded rod is threaded through the threaded tube, a knob is fixedly provided at one end of the threaded rod, a T-shaped block is rotatably connected to one end of the threaded rod, a movable plate is slidably provided inside the base plate, an inclined plate is fixedly provided on one side of the movable plate, the T-shaped block is in contact with the inclined plate, a positioning plate is fixedly provided on the side of the movable plate away from the inclined plate, and the positioning plate is movably inserted into the mounting plate. Inside the plate, the heat exchanger body is first welded to the bottom of the mounting plate. Then, the mounting plate is inserted into the base plate. Next, the knob is rotated, causing the threaded rod to rotate inside the threaded tube, which in turn causes the T-shaped block to slide inside the base plate. When the inclined surface of the T-shaped block coincides with the inclined surface of the inclined plate, it can push the two inclined plates away from each other, causing the two movable plates to move away from each other, and causing the movable block to slide in the groove. At the same time, the second spring is stretched, and the movable plate drives the positioning plate to insert into the mounting plate, thus enabling the heat exchanger body to be quickly installed. Then, when disassembly is required, the rotation of the threaded rod drives the T-shaped block to reset, causing the second spring to reset, and causing the movable plate to drive the positioning plate to disengage from the mounting plate, thus facilitating its disassembly.

[0006] By pulling the insert rod, the fixing ring is compressed against the first spring, which then pushes the first and second moving plates closer together, causing the limiting plate on one side of the first moving plate to insert into the limiting groove. Then, the insert rod is released, causing the first spring to return to its original position, allowing the insert rod to be inserted into the limiting plate. This facilitates the fixing of the first and second moving plates, enabling them to seal the heat exchanger body, reduce heat loss, improve energy efficiency, and reduce energy waste.

[0007] Preferably, movable blocks are fixedly provided on both sides of the movable plate, the movable blocks are slidably disposed in the base plate, the base plate has a groove, the movable blocks are slidably disposed in the groove, and a second spring is fixedly connected between the groove and the movable blocks. A limiting rod is fixedly provided in the groove, and the movable blocks are slidably disposed on the outer surface of the limiting rod.

[0008] Preferably, a first movable plate and a second movable plate are slidably provided on the top surface of the base plate. A top plate is fixedly provided inside both the first and second movable plates. A limiting plate is fixedly provided on one side of the first movable plate. A limiting groove is formed in the second movable plate. The limiting plate is movably inserted into the limiting groove. A sleeve is fixedly provided on one side of the second movable plate. An insert rod movably passes through the sleeve. The insert rod is movably inserted into the limiting plate. A fixing ring is fixedly sleeved on the outer surface of the insert rod. The fixing ring is slidably disposed in the sleeve. A first spring is fixedly connected between the inner wall of the sleeve and the fixing ring. A sliding groove is formed in the base plate. A slider is fixedly provided on the bottom surface of both the first and second movable plates. The slider is slidably disposed in the sliding groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, when the inclined surface of the T-shaped block coincides with the inclined surface of the inclined plate, the two inclined plates can be pushed away from each other, and the movable plate can drive the positioning plate to be inserted into the mounting plate, thereby enabling the heat exchanger body to be quickly installed, disassembled easily, and improving maintenance efficiency.

[0011] 2. In this utility model, the limiting plate on one side of the first moving plate is inserted into the limiting groove, and then the insertion rod is inserted into the limiting plate, which facilitates the fixing of the first moving plate and the second moving plate, so that the heat exchanger body can be sealed, reducing heat loss, improving energy utilization efficiency, and reducing energy waste.

[0020] 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.

[0021] Example: Figure 1-6As shown, this utility model provides a structurally improved high-efficiency wide-channel plate heat exchanger, including a base plate 1, a heat exchanger body 11 above the base plate 1, a mounting plate 12 welded to the bottom surface of the heat exchanger body 11, the mounting plate 12 being movably inserted into the base plate 1, a threaded tube 32 fixedly installed inside the base plate 1, a threaded rod 31 threaded through the threaded tube 32, a knob 3 fixedly installed at one end of the threaded rod 31, a T-shaped block 33 rotatably connected to one end of the threaded rod 31, a movable plate 35 slidably installed inside the base plate 1, an inclined plate 34 fixedly installed on one side of the movable plate 35, the T-shaped block 33 fitting against the inclined plate 34, and the movable plate 35 being away from the inclined plate 34. A positioning plate 37 is fixedly provided on one side of the plate 34. The positioning plate 37 is movably inserted into the mounting plate 12. By welding the lower part of the heat exchanger body 11 to the mounting plate 12, and then inserting the mounting plate 12 into the base plate 1, the knob 3 is rotated to cause the threaded rod 31 to rotate in the threaded tube 32, thereby driving the T-shaped block 33 to slide in the base plate 1. When the inclined surface of the T-shaped block 33 coincides with the inclined surface of the inclined plate 34, it can push the two inclined plates 34 away from each other, and cause the movable plate 35 to drive the positioning plate 37 to be inserted into the mounting plate 12. This allows for quick installation and disassembly of the heat exchanger body 11, improving maintenance efficiency.

[0022] Movable blocks 36 are fixedly provided on both sides of the movable plate 35. The movable blocks 36 are slidably disposed in the base plate 1. A groove 102 is provided in the base plate 1. The movable blocks 36 are slidably disposed in the groove 102. A second spring 39 is fixedly connected between the groove 102 and the movable blocks 36. A limiting rod 38 is fixedly provided in the groove 102. The movable blocks 36 are slidably disposed on the outer surface of the limiting rod 38.

[0023] By adopting the above technical solution, when the two movable plates 35 are far apart, they drive the movable block 36 to slide in the groove 102. At the same time, the second spring 39 is stretched. Then, when disassembly is required, the threaded rod 31 rotates to drive the T-shaped block 33 to reset, causing the second spring 39 to reset, so that the movable plate 35 can drive the positioning plate 37 to disengage from the mounting plate 12, thus facilitating its disassembly.

[0024] A first movable plate 2 and a second movable plate 22 are slidably provided on the top surface of the base plate 1. A top plate 25 is fixedly provided inside both the first movable plate 2 and the second movable plate 22. A limiting plate 21 is fixedly provided on one side of the first movable plate 2. A limiting groove 23 is opened in the second movable plate 22. The limiting plate 21 is movably inserted into the limiting groove 23. A sleeve 26 is fixedly provided on one side of the second movable plate 22. A rod 27 is movably inserted through the sleeve 26. The rod 27 is movably inserted into the limiting plate 21. A fixing ring 28 is fixedly sleeved on the outer surface of the rod 27. The fixing ring 28 is slidably provided in the sleeve 26. A first spring 29 is fixedly connected between the inner wall of the sleeve 26 and the fixing ring 28. A sliding groove 101 is opened in the base plate 1. A slider 24 is fixedly provided on the bottom surface of both the first movable plate 2 and the second movable plate 22. The slider 24 is slidably provided in the sliding groove 101.

[0025] By adopting the above technical solution, by pulling the insertion rod 27, the fixing ring 28 is squeezed by the first spring 29, and then the first moving plate 2 and the second moving plate 22 are pushed closer to each other, and the limiting plate 21 on one side of the first moving plate 2 is inserted into the limiting groove 23. Then the insertion rod 27 is released, causing the first spring 29 to return to its original position, and the insertion rod 27 can be inserted into the limiting plate 21, which facilitates the fixing of the first moving plate 2 and the second moving plate 22, so that the heat exchanger body 11 can be sealed, reducing heat loss, improving energy utilization efficiency, and reducing energy waste.

[0026] Working principle: First, the heat exchanger body 11 is welded to the mounting plate 12 at the bottom. Then, the mounting plate 12 is inserted into the base plate 1. Next, the knob 3 is rotated, causing the threaded rod 31 to rotate inside the threaded tube 32, which in turn causes the T-shaped block 33 to slide inside the base plate 1. When the inclined surface of the T-shaped block 33 coincides with the inclined surface of the inclined plate 34, it can push the two inclined plates 34 away from each other, causing the two movable plates 35 to move away from each other, and causing the movable block 36 to slide in the groove 102. At the same time, the second spring 39 is stretched, and the movable plate 35 causes the positioning plate 37 to be inserted into the mounting plate 12, thus enabling the heat exchanger body 11 to be quickly installed. Then, when disassembly is required, the threaded rod 31 rotates, causing the T-shaped block 33 to return to its original position, causing the second spring 39 to return to its original position, and causing the movable plate 35 to drive the positioning plate 37 to disengage from the mounting plate 12, thus facilitating its disassembly.

[0027] By pulling the insertion rod 27, the fixing ring 28 is compressed against the first spring 29, which then pushes the first moving plate 2 and the second moving plate 22 closer together, and the limiting plate 21 on one side of the first moving plate 2 is inserted into the limiting groove 23. Then the insertion rod 27 is released, causing the first spring 29 to return to its original position, and the insertion rod 27 can then be inserted into the limiting plate 21, which facilitates the fixing of the first moving plate 2 and the second moving plate 22, enabling them to seal the heat exchanger body 11, reduce heat loss, improve energy utilization efficiency, and reduce energy waste.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
