Description

Technical Field

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

[0002] The plate heat exchanger is a high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and light structure, small footprint, wide application, and long service life. In the plate heat exchanger, heat is exchanged through plates. Under the influence of high temperature and pressure, the plates inside the heat exchanger cause blockage in the rectangular channels inside, thereby affecting the passage of gas and liquid. It is inconvenient to replace damaged plates, and the existing plate heat exchangers are not convenient to disassemble and assemble, so it is inconvenient to repair them.

[0003] The patent name is "CN218155670U", which is published as: A plate heat exchanger that is easy to replace the heat exchanger fins. The public document solves the above problems, but the device in the public document needs to first remove the top of the support rod by using the fixing bolts, and then rotate the fixing rod in the opposite direction to remove the fixing rod from the inside of the threaded tube, so that one end of the support plate can be separated from the support rod, and then the movable clamping plate is moved out from the outside of the support plate and the fixed clamping plate, and then the adjusting rod is pulled to release the fixation of the movable clamping plate, and then the movable clamping plate is removed from the outside of the support tube, so that the damaged heat exchange plate can be removed from the outside of the support tube for replacement. As can be seen from the above, this method of replacing the heat exchange plate is cumbersome, time-consuming and labor-intensive, which not only increases the difficulty of the staff's work, but also affects the efficiency of replacing the heat exchange plate. Based on this, the utility model designs a detachable heat exchanger to solve the above problems. Utility Model Content

[0028] Example 1

[0029] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, the device includes a frame 1, a feed pipe 2 and a discharge pipe 3. The feed pipe 2 is fixed at the upper end of the frame 1, and the discharge pipe 3 is fixed at the lower end of the frame 1. The feed pipe 2 and the discharge pipe 3 are provided with a clearance groove 4 through a transverse array. The upper and lower ends of the frame 1 are provided with a guide groove 5 through a transverse array. The left side of the frame 1 is provided with a discharge hole 6. A detachable heat exchange component 7 is provided in the guide groove 5. The heat exchange component 7 includes a heat exchange plate 701 arranged in the guide groove 5. Rubber mounting sleeves 702 are slidably penetrated at the four corners of the heat exchange plate 701, and a mounting plate 703 fixed on the inner side of the mounting sleeve 702 is slidably connected to the heat exchange plate 701. The mounting sleeve 702 is designed to be conical.

[0030] The clearance hole 8 integrally arranged at the middle end of the mounting plate 703 is designed as a through hole, the guide hole 9 integrally arranged inside the mounting sleeve 702 is designed as a through hole, a first partition plate 10 is fixedly arranged at the middle end of the heat exchange plate 701, and a second partition plate 11 is fixedly arranged on the left and right sides of the middle end of the outer wall of the first partition plate 10, and the second partition plate 11 is fixedly connected to the heat exchange plate 701, and the avoidance holes 12 integrally arranged at the upper and lower ends of the first partition plate 10 correspond one to one with the clearance holes 8, and the avoidance holes 12 are designed as through holes, and springs 13 are fixedly arranged at the upper and lower ends of the inner side of the mounting plate 703, and the end of the spring 13 away from the mounting plate 703 is fixedly connected to the outer wall of the first partition plate 10. First, the gas or liquid is discharged from the feed pipe 2 through the guide hole 9, the give way hole 8 and the avoidance hole 12 at the upper end into the upper end of the heat exchange plate 701, and then passes through the discharge hole 6 and the lower end of the heat exchange plate 701 and is discharged from the discharge pipe 3. In the above manner, the gas or liquid first passes through the upper ends of several heat exchange plates 701 from right to left and then passes through the lower ends of several heat exchange plates 701 from left to right for heat exchange treatment.

[0031] Example 2

[0032] like Figure 1 , Figure 3 As shown, connecting plates 14 are fixedly provided on the upper and lower sides of the front end of the outer wall of the heat exchange plate 701, a rotating rod 15 is connected inside the connecting plate 14, and screw pins 16 are threadedly provided at the upper and lower ends of the rotating rod 15, the screw pin 16 at the upper end is designed to be connected with the rotating rod 15 by a left thread, and the screw pin 16 at the lower end is designed to be connected with the rotating rod 15 by a right thread, and a limiting rod 17 with a square cross-section is fixedly provided on the outside of the screw pin 16, and supporting plates 18 are fixedly provided on the upper and lower sides of the front end of the outer wall of the heat exchange plate 701, and the supporting plates 18 are slidably sleeved on the outside of the limiting rod 17, and placement plates 19 are fixedly provided on the upper and lower sides of the front end of the outer wall of the frame 1 in a transverse array manner, and the placement plates 19 correspond to the guide grooves 5 and the clearance grooves 4 one by one, and a socket 20 is integrally provided inside the placement plate 19, and the socket 20 is a through hole design, and the socket 20 and the limiting rod 17 can be disassembled and assembled by plugging.

[0033] According to the operation steps in Example 1, when the heat exchange plate 701 needs to be replaced, first turn the rotating rod 15 forward, and through the threaded transmission of the rotating rod 15 and the screw pin 16, the screw pins 16 at the upper and lower ends drive the limit rod 17 to move along the direction of the support plate 18, that is, two limit rods 17 move towards each other, so that the limit rod 17 is disengaged from the plug hole 20, and then pull the rotating rod 15, so that the rotating rod 15 drives the connecting plate 14 together with the heat exchange plate 701 to separate from the frame 1, and then insert the new heat exchange plate 701 into the inside of the make way groove 4 and the guide groove 5. At this time, the outer walls of the feed pipe 2 and the discharge pipe 3 are installed in a conical state. The inclined surface of the sleeve 702 applies an extrusion pressure, thereby moving the installation sleeve 702 into the heat exchange plate 701, and deforming the spring 13 until the installation sleeve 702 overlaps with the interior of the feed pipe 2 and the discharge pipe 3. The spring 13 then allows the installation sleeve 702 to be inserted into the interior of the feed pipe 2 and the discharge pipe 3. At this time, the rubber installation sleeve 702 seals the state of the heat exchange plate 701 and the frame 1 after connection. The staff then reverses the turning rod 15, and the operation method is the same as the above prevention, that is, the two opposing limit rods 17 are inserted into the socket 20, so that the replaced heat exchange plate 701 is firmly connected to the frame 1.
