[0035] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0036] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 4 As shown, an embodiment of the present invention provides a detachable plate heat exchanger, comprising:

[0038] Fixed plate 1;

[0039] Plate 2: There are a plurality of plates 2, which are fitted together, and the opposite sides of the front and rear plates 2 are fitted to the opposite side of the fixed plate 1;

[0040] There are four fixing components 3, all of which are arranged on the outer surface of the plate 2. The fixing components 3 include:

[0041] First fixing post 301: The rear end face of the first fixing post 301 is fixedly connected to the opposite side of the fixing plate 1, and the outer surface of the first fixing post 301 is in contact with the outer surface of the plate 2;

[0042] Slot 302: The slot 302 is formed on the outer surface of the first fixing column 301;

[0043] Latch 303: The outer surface of the latch 303 fits in contact with the inner wall of the slot 302;

[0044] Second fixing post 304 : The outer surface of the second fixing post 304 is fixedly connected to the opposite end of the latch 303 , the second fixing post 304 and the first fixing post 301 are in contact with each other, and the outer surface of the second fixing post 304 is in contact with the outer surface of the plate 2 .

[0045] refer to Figure 3 As shown, a sliding groove 4 is provided on the outer surface of the front fixing plate 1 , and four sliding grooves 4 are provided. The inner walls of the four sliding grooves 4 are slidably connected to the outer surface of the second fixing column 304 .

[0046] The above solution is adopted: the plate 2 is installed between the fixed plates 1, and then the second fixing column 304 is moved to the opposite side until the distance between the first fixing column 301 and the second fixing column 304 is greater than or equal to the distance between the pin 303 and the slot 302. The opposite side of the two fixing plates 1 can be fitted with the plate 2, so that the pin 303 on the second fixing column 304 corresponds to the slot 302 on the first fixing column 301. Finally, the second fixing column 304 is moved to the opposite side until the pin 303 is completely inserted into the slot 302, thereby achieving the purpose of positioning and fixing.

[0047] refer to Figure 3 As shown, the outer surface of the second fixing column 304 is provided with an auxiliary component 5, and four auxiliary components 5 are provided. The four auxiliary components 5 include:

[0048] Telescopic spring 501: One side of the telescopic spring 501 is fixedly connected to the outer surface of the second fixing column 304, and the other side of the telescopic spring 501 is fixedly connected to the inner wall of the sliding groove 4;

[0049] Fixed blocks 502 : There are two fixed blocks 502 , the rear ends of the two fixed blocks 502 are fixedly connected to the front ends of the second fixed columns 304 , and a travel assembly 6 is provided between the fixed blocks 502 .

[0050] Adopting the above scheme: when the second fixing column 304 moves to the opposite side, the second fixing column 304 can squeeze the telescopic spring 501, so that the telescopic spring 501 generates elastic force. When the pin 303 corresponds to the slot 302, the telescopic spring 501 can release the elastic force, pushing the second fixing column 304 to fit together with the first fixing column 301. The telescopic spring 501 mainly plays a fault-tolerant effect, preventing the second fixing column 304 from moving back after fitting together with the first fixing column 301.

[0051] refer to Figure 4 As shown, there are four stroke components 6, and the four stroke components 6 include:

[0052] Travel column 601: The upper and lower ends of the travel column 601 are fixedly connected to the opposite side of the fixed block 502;

[0053] Travel groove 602: The inner wall of the travel groove 602 is slidably connected to the outer surface of the travel column 601, and a rotating component 7 is provided on the outer surface of the travel groove 602.

[0054] The above solution is adopted: in order to move the second fixed column 304 to the opposite side, the travel groove 602 is rotated outward, and the inner wall of the travel groove 602 can squeeze the outer surface of the travel column 601, so that the travel column 601 moves along the inner wall of the travel groove 602. The travel column 601 can drive the fixed block 502 to move to the opposite side, and the fixed block 502 drives the second fixed column 304 to move to the opposite side.

[0055] refer to Figure 4 As shown, there are four rotating assemblies 7, and the four rotating assemblies 7 include:

[0056] Rotating member 701: The inner surface of the rotating member 701 is fixedly connected to the outer surface of the travel groove 602;

[0057] Support rod 702: The outer surface of the support rod 702 is fixedly connected to the inner surface of the rotating member 701, and the outer surface of the support rod 702 is provided with a driving component 8.

[0058] The above solution is adopted: in order to make the travel groove 602 rotate outward, the support rod 702 is rotated, and the support rod 702 can drive the rotating member 701 to rotate outward, so that the rotating member 701 drives the travel groove 602 to rotate outward together.

[0059] refer to Figure 3 As shown, there are four drive assemblies 8, and the four drive assemblies 8 include:

[0060] Worm gear 801: The inner surface of the worm gear 801 is fixedly connected to the outer surface of the support rod 702;

[0061] Worm 802: The outer surface of the worm 802 and the outer surface of the worm wheel 801 are in a mutually meshing relationship;

[0062] Driving rod 803: The driving rod 803 passes through the surface of the worm 802;

[0063] Driving member 804: The rear end surface of the driving member 804 is fixedly connected to the front end surface of the driving rod 803.

[0064] The above solution is adopted: in order to make the support rod 702 rotate, by rotating the driving member 804, the driving member 804 can drive the driving rod 803 to rotate together, and the driving rod 803 drives the worm 802 to rotate. The worm 802 rotates and engages with the outer surface of the worm wheel 801, so that the worm wheel 801 is forced to rotate, and the worm wheel 801 drives the support rod 702 to rotate together, playing a driving role.

[0065] refer to Figure 1As shown, a protective shell 9 is provided on the front end face of the fixed plate 1. There are four protective shells 9. The rear end faces of the four protective shells 9 are fixedly connected to the front end face of the fixed plate 1. The inner wall of the protective shell 9 is rotatably connected to the upper and lower ends of the support rod 702 and the rear end face of the driving rod 803 through a rotating shaft.

[0066] With the above solution, the protective shell 9 mainly plays the role of protecting the components inside the protective shell 9 .

[0067] When in use, by rotating the driving member 804, the driving member 804 can drive the driving rod 803 to rotate together, and the driving rod 803 drives the worm 802 to rotate. The worm 802 rotates and engages with the outer surface of the worm wheel 801, so that the worm wheel 801 is forced to rotate, and the worm wheel 801 drives the support rod 702 to rotate together. The support rod 702 can drive the rotating member 701 to rotate outward, so that the stroke groove 602 on the inner surface of the rotating member 701 rotates outward, and the inner wall of the stroke groove 602 can squeeze the outer surface of the stroke column 601, so that the stroke column 601 moves along the inner wall of the stroke groove 602, and the stroke column 601 can drive the fixed block 502 to move to the opposite side. 502 then drives the second fixing post 304 to move to the opposite side, and the second fixing post 304 can squeeze the telescopic spring 501, causing the telescopic spring 501 to generate elastic force until the distance between the first fixing post 301 and the second fixing post 304 is greater than or equal to the distance between the latch 303 and the slot 302, and the two fixing plates 1 can be fitted with the opposite side of the plate 2, so that the latch 303 on the second fixing post 304 corresponds to the slot 302 on the first fixing post 301. Finally, the driving member 804 is rotated in the opposite direction to move the second fixing post 304 to the opposite side, and the telescopic spring 501 releases the pressure until the latch 303 is completely inserted into the slot 302, completing the fixed position;

[0068] When disassembly is required, similarly, the driving member 804 is rotated to make the latch 303 leave the interior of the slot 302, thereby separating the first fixing column 301 and the second fixing column 304, and completing the disassembly.

[0069] To sum up: this detachable plate heat exchanger, through the fixing plate 1, plate 2, fixing component 3, sliding groove 4, auxiliary component 5, stroke component 6, rotating component 7, driving component 8 and protective shell 9, solves the problem that when disassembling the existing plate heat exchanger, professional tools are needed to remove the bolts, and the disassembly process is relatively cumbersome. If the bolts are lost during the disassembly process, the plate heat exchanger cannot be installed stably when it is installed again, and the bolts need to be re-paired. The process consumes a lot of time and affects the efficiency of reuse.
