Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a detachable plate heat exchanger. Background Technique

[0002] A plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. During the operation of the plate heat exchanger, due to various reasons, a lot of dirt such as coking, oil dust, water scale, sediment, corrosion products, polymers, fungi, algae, and slime often appears in the heat exchanger and pipelines. Therefore, it needs to be disassembled for maintenance.

[0003] After retrieval, the patent document with the publication number: CN218380610U discloses a detachable plate heat exchanger, which clamps multiple plates through two movable clamping plates, and then locks them through multiple clamping screws and nuts, and extrudes them onto the outer walls of the two movable clamping plates to fix the positions of the multiple plates; in the actual process of turning the nut, since it is necessary to ensure the tight fit state between the multiple plates, the nut needs to be tightened repeatedly. During the process of tightening the nut, the friction coefficient between the clamping screw and the movable clamping plate is small, resulting in the rotation of the clamping screw as the tightening process progresses, and a wrench needs to be taken out separately to fix one end of the clamping screw; and subsequently, as the nut is continuously extruded onto the outer wall of the movable clamping plate, the friction force between the two increases, which also leads to an increase in the required force, and the overall operation is cumbersome. Therefore, we propose a detachable plate heat exchanger to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a detachable plate heat exchanger.

Specific embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0021] As Figures 1 - 3 shown, it relates to a detachable plate heat exchanger, including two movable clamping plates 1. A plurality of plates 2 are arranged between the two movable clamping plates 1, and two docking pipes 3 are fixedly communicated with the outer walls of the two movable clamping plates 1.

[0022] A plurality of concave holes 4 are evenly formed in the outer walls of the two movable clamping plates 1. The inner walls of the two concave holes 4 are slidably connected with the same guide rod 5. A diamond sleeve 6 is slidably sleeved on the outer wall of the guide rod 5. An arc-shaped stopper 7 is fixedly connected to the outer wall of the diamond sleeve 6. The arc-shaped stopper 7 is located in the concave hole 4. The diamond sleeve 6 and the arc-shaped stopper 7 are used in cooperation to prevent the long nut 8 from rotating.

[0023] A long nut 8 is fixedly sleeved on the outer wall of the guide rod 5. The outer wall of the long nut 8 is slidably connected with the inner wall of the diamond sleeve 6. The long nut 8 is located in the diamond sleeve 6, and the diamond sleeve 6 limits it.

[0024] A locking mechanism is provided on the outer wall of the guide rod 5. The locking mechanism includes a plurality of gaskets 9. The outer walls of the plurality of guide rods 5 are respectively slidably connected to the inner walls of the plurality of gaskets 9. A cap 10 is rotatably sleeved on the outer wall of the gasket 9. A plurality of balls 11 are installed between the cap 10 and the gasket 9. The cap 10 and the gasket 9 rotate through the plurality of balls 11. A locking nut 12 is threadedly sleeved on the outer wall of the guide rod 5. The outer wall of the locking nut 12 is pressed against the outer wall of the cap 10. The locking nut 12 rotates without contacting the movable clamping plate 1. The formed pressing force is transmitted to the gasket 9 and then the movable clamping plate 1 is clamped.

[0025] A limiting mechanism is provided on the outer wall of the guide rod 5. The limiting mechanism includes two first L-shaped plates 13. The outer walls of the two guide rods 5 are respectively slidably connected to the outer walls of the two first L-shaped plates 13. The outer walls of the two guide rods 5 are both slidably connected with second L-shaped plates 14. A T-shaped block 15 is fixedly connected to the outer wall of the first L-shaped plate 13. A T-shaped long groove is formed in the outer wall of the second L-shaped plate 14. The inner wall of the T-shaped long groove is slidably connected to the outer wall of the T-shaped block 15.

[0026] A plurality of threaded holes 16 are formed in the outer walls of both the first L-shaped plate 13 and the second L-shaped plate 14. A countersunk bolt is threadedly connected to the inner wall of the threaded hole 16 to fix the first L-shaped plate 13 and the second L-shaped plate 14. And the diameter of the threaded hole 16 is smaller than the width of the T-shaped long groove, without affecting it. Assembly holes are formed in the outer walls of both the first L-shaped plate 13 and the second L-shaped plate 14. The inner wall of the assembly hole is in contact with the outer wall of the guide rod 5. The inner wall of the assembly hole is matched with the outer wall of the guide rod 5.

[0027] Working principle: When in use, stack multiple plates 2 through two movable clamping plates 1, then slide multiple guide rods 5 into two concave holes 4 in sequence. Slide the diamond-shaped sleeve 6 onto one end of the guide rod 5, and place the arc-shaped stopper 7 in the concave hole 4. Slide the long nut 8 into the diamond-shaped sleeve 6, and put the gasket 9 and the cap 10 onto the other end of the guide rod 5. Rotate the locking nut 12 to press it against the outer wall of the cap 10. During the rotation of the locking nut 12, when the guide rod 5 drives the long nut 8 to rotate under force, since the long nut 8 is located in the diamond-shaped sleeve 6, the diamond-shaped sleeve 6 is driven to rotate through the concave cross-section of the diamond-shaped sleeve 6. And because the arc-shaped stopper 7 is located in the concave hole 4 and the rotation of the arc-shaped stopper 7 is restricted, it is ensured that the guide rod 5 will not rotate with the rotation of the locking nut 12. At the same time, after the two movable clamping plates 1 apply a squeezing force to the multiple plates 2, the force required for the locking nut 12 to rotate increases. The locking nut 12 drives the cap 10 to rotate, and there are balls 11 between the cap 10 and the gasket 9. The friction is reduced through the balls 11, and the squeezing force applied by the locking nut 12 is transmitted to the gasket 9 in sequence, which is convenient for rotating the locking nut 12 and also facilitates the subsequent disassembly of the two movable clamping plates 1 and the multiple plates 2. Divide the two first L-shaped plates 13 and the two second L-shaped plates 14 into two groups, with the two groups arranged vertically. Move the first L-shaped plate 13 and the second L-shaped plate 14 through the T-shaped block 15 and the T-shaped long groove, slide the assembly holes on the first L-shaped plate 13 and the second L-shaped plate 14 onto the two guide rods 5, and rotate the counterbore bolt into the threaded hole 16 to complete the fixation. The first L-shaped plate 13 and the second L-shaped plate 14 limit the two guide rods 5 in contact to prevent displacement after being collided.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to only the specific implementation manners.
