DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The utility model discloses a modular combined economizer, such as Figure 1-5 As shown, it includes a combination frame 1, a limiting plate 7 is fixedly installed inside the combination frame 1, a low-temperature heat exchange component 2 for heat exchange is provided on the top surface of the limiting plate 7, a plurality of arc grooves are opened on the top surface of the limiting plate 7, and the low-temperature heat exchange component 2 is placed in the plurality of arc grooves, and the pipes of the low-temperature heat exchange component 2 are respectively placed in the plurality of arc grooves, and a driving frame 3 is fixedly installed on both sides of the outer surface of the combination frame 1.

[0024] A first threaded rod 301 is movably installed on one side of the interior of the two driving frames 3, and a sliding rod 302 is fixedly installed on the other side of the interior of the two driving frames 3. The outer surfaces of the two first threaded rods 301 are threadedly connected with moving blocks 303, and the two moving blocks 303 are movably connected to the two sliding rods 302 respectively. When the two first threaded rods 301 rotate, the two moving blocks 303 can be moved, and the sliding rod 302 can prevent the moving blocks 303 from rotating with the rotation of the first threaded rods 301.

[0025] The top surfaces of the two moving blocks 303 are movably mounted with driving rods 304, and the two driving rods 304 are movably connected to a fixing bar 305 on one side away from the moving blocks 303. When the two moving blocks 303 move in opposite directions, the two driving rods 304 can push the fixing bar 305 to rise and fall to clamp and fix the low-temperature heat exchange component 2.

[0026] Limiting sleeves 101 are movably installed on both sides of the top surface of the combination frame 1, and second threaded rods 102 are movably installed on both sides of the bottom surface of the combination frame 1, and the two second threaded rods 102 are respectively threadedly connected with the two limiting sleeves 101. By rotating the second threaded rod 102, the limiting sleeves 101 can be raised and lowered, and the two limiting sleeves 101 can fix the two sides of the low-temperature heat exchange component 2. When the low-temperature heat exchange component 2 needs to be disassembled, the low-temperature heat exchange component 2 can be removed by simply rotating the first threaded rod 301 and the second threaded rod 102 to facilitate its replacement or maintenance.

[0027] Combination sleeves 4 are fixedly installed on both sides of the top surface of the combination frame 1, telescopic sleeves 401 are fixedly installed on one side of the outer surfaces of the two combination sleeves 4, springs 402 are fixedly installed inside the two telescopic sleeves 401, fixed rods 403 are fixedly installed on one end of the two springs 402, and pull rods 404 are fixedly installed on one side of the two fixed rods 403. By pulling the pull rods 404, the fixed rods 403 can squeeze the springs 402, so that the fixed rods 403 are retracted into the combination sleeves 4, and mounting columns 6 are fixedly installed on both sides of the bottom surface of the combination frame 1, and holes are opened on one side of the two mounting columns 6.

[0028] When two combination frames 1 need to be combined and connected, the two combination frames 1 are stacked so that the two mounting posts 6 of one combination frame 1 are inserted into the two combination sleeves 4 of the other combination frame 1. After the mounting posts 6 are inserted into the combination sleeves 4, the pull rod 404 is released, and the fixing rod 403 can be pushed under the action of the spring 402 to be inserted into the hole of the mounting post 6.

[0029] Both sides of the top surface of the combination frame 1 are provided with connection grooves 103, and both sides of the outer surfaces of the two connection grooves 103 are provided with fixing holes 104. Both sides of the bottom surface of the combination frame 1 are fixedly installed with connection blocks 5, and one side of the two connection blocks 5 is provided with connection holes 501. When two combination frames 1 are stacked and connected, the connection blocks 5 on both sides of one combination frame 1 will be inserted into the connection groove 103 of the other combination frame 1, and the connection hole 501 will overlap with the fixing hole 104. Then, the bolts are inserted to combine the two combination frames 1. The above steps can be repeated in sequence to stack and combine multiple combination frames 1.

[0030] The working principle of the utility model is as follows: the low-temperature heat exchange component 2 is placed in the arc groove on the top surface of the limiting plate 7, and then, the two first threaded rods 301 are rotated at the same time. When the two first threaded rods 301 are rotated, the two moving blocks 303 can be moved, so that the two moving blocks 303 move in opposite directions until the fixing bar 305 descends and contacts with the low-temperature heat exchange component 2. After that, the two second threaded rods 102 are rotated in sequence. As the second threaded rods 102 rotate, the two limiting sleeves 101 can be descended until the inner wall of the limiting sleeves 101 contacts with the low-temperature heat exchange component 2, so that the connection between the low-temperature heat exchange component 2 and the combination frame 1 can be completed. When disassembly is required, only the first threaded rod 301 and the second threaded rod 1 need to be rotated. 02, so that the limiting sleeve 101 and the fixing strip 305 are away from the low-temperature heat dissipation component, and they can be disassembled. When it is necessary to combine and connect the two combination frames 1, the two combination frames 1 are superimposed so that the two mounting posts 6 of one combination frame 1 are inserted into the two combination sleeves 4 of the other combination frame 1. After the mounting posts 6 are inserted into the combination sleeves 4, the pull rod 404 is released. Under the action of the spring 402, the fixing rod 403 can be pushed to be inserted into the hole of the mounting post 6. In this process, the connecting blocks 5 on both sides of one combination frame 1 will be inserted into the connecting groove 103 of the other combination frame 1, and the connecting hole 501 will coincide with the fixing hole 104. Then, the bolts are inserted to make the two combination frames 1 combined and connected.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
