Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a plate heat exchanger which is easy to disassemble. Background Art

[0002] The plate heat exchanger is a new type of high-efficiency heat exchanger made of a series of stacked 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.

[0003] According to the existing patent CN219454778U plate heat exchanger, after the operator starts the motor to rotate, the motor drives the transmission screw to rotate through the synchronous belt, so that the sealing ring and the plate body are close to or away from each other, thereby realizing the connection or disassembly of the plate body, which is simple and convenient; through the setting of the transmission belt, all threaded rods can be driven by the rotation of one threaded rod, thereby realizing the synchronous rotation of all threaded rods, saving time and effort; through the setting of the fastening ring, the connecting seat and the connecting head are inserted into the connecting hole to squeeze the fastening ring, so that the connection between the connecting head and the connecting seat and the inner wall of the connecting hole is more stable, and then the fixing of the connecting seat and the connecting head to the plate body is more stable; through the setting of the sealing ring, the plate bodies are abutted by the sealing ring when connected, thereby strengthening the sealing between the plate bodies, and when disassembling, the plate body damaged by leakage can be quickly replaced without affecting other plate bodies, and the heat-conducting liquid in other plate bodies will not flow out, which is safer.

[0004] In the above-mentioned comparative documents, when one of the heat exchange plates is damaged, the entire device needs to be disassembled, which makes maintenance inconvenient and reduces work efficiency. When the distance between the heat exchange plates is close, the sealing ring will be over-squeezed, resulting in a decrease in the liquid circulation speed inside the plate body. Therefore, the utility model proposes a plate heat exchanger that is easy to disassemble. Utility Model Content

[0011] As a preferred embodiment, first connecting sleeves are provided on both sides of the first connecting hole and the first water injection hole on the first heat exchange plate, and the first connecting sleeves are communicated with the first connecting hole and the first water injection hole.

[0019] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] 1. In the utility model, under the action of the second push rod, the connecting plate is driven to move up and down, so that the distance between the upper fixing rod and the lower fixing rod is increased or decreased. Since the first heat exchange plate and the second heat exchange plate are arranged between the upper fixing rod and the lower fixing rod in a sliding and clamping manner, when the distance between the upper fixing rod and the lower fixing rod increases, the first heat exchange plate and the second heat exchange plate are released from the limited state between the upper fixing rod, so that the damaged first heat exchange plate or the second heat exchange plate can be directly removed from the installation assembly for replacement, thereby improving the practicality of the device.

[0021] 2. In the utility model, since the first heat exchange plate and the second heat exchange plate are both independently designed heat exchange plate bodies, compared with the heat exchange plate with a sealing ring, this structure improves the sealing during heat exchange, and further, under the action of the first heat exchange cavity and the second heat exchange cavity, a certain space can be reserved for liquid circulation, avoiding the internal liquid from not circulating due to excessive squeezing of the first heat exchange plate or the second heat exchange plate, thereby improving the stability of the device during use.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-5 As shown, the utility model provides a technical solution: a plate heat exchanger that is easy to disassemble, including a plate heat exchanger body 1, the plate heat exchanger body 1 includes a mounting assembly 2, two mounting assemblies 2 are provided, and a lower fixing rod 26 and an upper fixing rod 25 are provided between the two mounting assemblies 2; the two ends of the lower fixing rod 26 are respectively connected to the two mounting frames 21, the upper fixing rod 25 is slidably connected to the two mounting frames 21, and the upper fixing rod 25 is located at one end of the mounting frame 21 and is provided with a connecting plate 24, and the mounting frame 21 is provided with a second push rod 27, and the second push rod 27 is connected to the connecting plate 24, and the first heat exchange plate 3 and the second heat exchange plate 4 are sequentially arranged between the lower fixing rod 26 and the upper fixing rod 25; the first heat exchange plate 3 and the second heat exchange plate 4 are sequentially staggered and slidably connected to the upper fixing rod 25 and the upper fixing rod 25 A first push rod 22 is provided on one of the mounting frames 21, and an output end of the first push rod 22 passes through the mounting frame 21. A push plate 23 is provided on one end of the first push rod 22 passing through the mounting frame 21. Under the action of the second push rod 27, the connecting plate 24 is driven to move up and down, so that the distance between the upper fixing rod 25 and the lower fixing rod 26 increases or decreases. Since the first heat exchange plate 3 and the second heat exchange plate 4 are arranged between the upper fixing rod 25 and the lower fixing rod 26 in a sliding card manner, when the distance between the upper fixing rod 25 and the lower fixing rod 26 increases, the first heat exchange plate 3 and the second heat exchange plate 4 are released from the limiting state between the upper fixing rod 25, so that the damaged first heat exchange plate 3 or the second heat exchange plate 4 can be directly removed from the mounting assembly 2 for replacement, thereby solving the technical problem of difficulty in disassembling the heat exchange plate.

[0030] Further, such as Figure 4 - Figure 5As shown: the first heat exchange plate 3 is provided with first card interfaces 31 at four corners, the first heat exchange plate 3 is slidably connected to the upper fixing rod 25 and the lower fixing rod 26 through the first card interfaces 31, the first heat exchange plate 3 is provided with a first connecting hole 34 and a first water injection hole 35, two first connecting holes 34 and two first water injection holes 35 are respectively provided, the first heat exchange plate 3 is provided with a first heat exchange cavity 32 connected with the two first water injection holes 35, the first heat conduction plates 33 are embedded and installed on both sides of the first heat exchange cavity 32 of the first heat exchange plate 3, and the first connecting sleeves 36 are provided on both sides of the first connecting hole 34 and the first water injection hole 35 of the first heat exchange plate 3. The first connecting sleeve 36 is communicated with the first connecting hole 34 and the first water injection hole 35. The second heat exchange plate 4 is provided with second card interfaces 41 at four corners. The second heat exchange plate 4 is slidably connected to the upper fixing rod 25 and the lower fixing rod 26 through the second card interfaces 41. The second heat exchange plate 4 is provided with a second connecting hole 44 and a second water injection hole 45.

The second connecting sleeve 46 is connected with the second connecting hole 44 and the second water injection hole 45. The first heat exchange plate 3 ensures that the first heat exchange plate 3 can reserve a minimum flow space when it is squeezed through the first heat exchange cavity 32, so as to avoid excessive squeezing and causing a decrease in flow rate. Further, the first heat conducting plate 33 is in contact with the second heat conducting plate 43 to achieve heat exchange, and the heat exchange efficiency is improved under the action of the first heat conducting plate 33 and the second heat conducting plate 43. The first connecting sleeve 36 makes the multiple first connecting holes 34 and the first water injection holes 35 connected through the first connecting sleeve 36 and the second connecting hole 44 and the second water injection hole 45, thereby solving the technical problem that the internal liquid of the first heat exchange plate 3 and the second heat exchange plate 4 cannot circulate after excessive squeezing.

[0031] The above solution still has the problem of connection between the first heat exchange plate 3 and the second heat exchange plate 4, such as Figure 5 As shown: a set component 5 is arranged between two adjacent first heat exchange plates 3 and second heat exchange plates 4, and the set component 5 includes a set frame 51. There are two set frames 51 in total, and a connecting shaft 52 is rotatably connected between the two set frames 51. The second connecting sleeve 46 and the first connecting sleeve 36 are slidably connected in the set frame 51. The set component 5 is used to limit the position between the two adjacent first connecting sleeves 36 to prevent the two first connecting sleeves 36 from separating during use. The set component 5 is a detachable structure, and the set frame 51 can be quickly removed from the two first connecting sleeves 36 during use.

[0032] Working principle: Figure 1-5 As shown, firstly, the plate heat exchanger body 1 is placed in the specified position, and the first heat exchange plate 3 and the second heat exchange plate 4 are clamped on the upper fixing rod 25 in a staggered placement manner. After the clamping is completed, the second push rod 27 is opened to drive the connecting plate 24 to move downward, so that the first clamping interface 31 and the second clamping interface 41 are clamped with each other, and the first heat exchange plate 3 and the second heat exchange plate 4 are limited. At this time, the set component 5 is clamped on the two adjacent first connecting sleeves 36 of the first heat exchange plate 3 and the second heat exchange plate 4, and the set frame 51 is clamped between the two first connecting sleeves 36, and the two set frames 51 are limited by the limit bolt to prevent the expansion of the set frame 51 during use and cause the two first connecting sleeves 36 to separate. After the installation is completed, the first push rod 22 is controlled to drive the push plate 23 to move to one side of the first heat exchange plate 3 to squeeze the first heat exchange plate 3 and the second heat exchange plate 4. At this time, the pipeline is fixedly connected to the outermost first connecting sleeve 36, and the installation is completed. The water pump is turned on for heat exchange.
