DETAILED DESCRIPTION

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0026] like Figure 1-Figure 8 As shown, a heat exchanger that is easy to maintain includes a support frame 1, characterized in that four guide pipes 2 are arranged on the support frame 1, and the four guide pipes 2 are symmetrically distributed. A plurality of heat exchange plates 3 are arranged between two support frames 1, and the lower ends of the heat exchange plates 3 are placed on the lower guide rod 101. The two ends of the lower guide rod 101 are fixed to the support frame 1 with bolts, and an upper guide rod 102 is arranged on the top of the heat exchange plate 3. A fixing component 4 is arranged on one side of the two support frames 1, and a collecting device 5 is arranged at the bottom of the lower guide rod 101. The fixing component 4 includes a fixing component 4 fixed on The device box 401 on one side of the support frame 1 has a gear 402 rotatably connected inside the device box 401. The center of the gear 402 is connected to the motor 6 installed on the side of the device box 401. Two tooth plates 403 are meshed at the upper and lower ends of the gear 402. The two tooth plates 403 pass through the openings on one side of the device box 401 and are slidably connected inside the device box 401. A spring 404 is fixed in the top cavity of the tooth plate 403. A block 405 is connected to the bottom of the spring 404. Both ends of the block 405 are arc-shaped surfaces and are inserted into the top groove of the upper guide rod 102.

[0027] As mentioned above, in this case, when in use, the motor 6 is started, the motor 6 drives the gear 402 to rotate, and the gear 402 rotates to drive the two tooth plates 403 to move, so that the block 405 at the top of the tooth plate 403 moves inward. During the movement, when the block 405 contacts the upper guide rod 102, the block 405 is squeezed and the spring 404 is compressed. When the block 405 moves to the groove above the upper guide rod 102, the block 405 is ejected by the spring 404 and inserted into the groove. The device stops moving to fix the upper guide rod 102. When it is necessary to maintain the heat exchange plate 3, the motor 6 is started to drive The gear 402 rotates in the opposite direction, and after the block 405 leaves the upper guide rod 102, the upper guide rod 102 is taken out, and the heat exchange plate 3 can be taken out from the top for maintenance. The two ends of the block 405 are designed as arc surfaces, which can make it easier for the block 405 to move up and down during the movement. During the operation of the heat exchanger, the fluid passes through the heat exchange plate 3 from the guide tube 2 to form a loop. A collecting device 5 is placed at the bottom of the heat exchange plate 3 to collect the fluid dripping during the operation. The motor 6 is used to control the fixing component 4 to fix and remove the device, thereby improving work efficiency and facilitating disassembly and maintenance.

[0028] The fixing blocks 1021 at both ends of the upper guide rod 102 are set to be square, and the fixing blocks 1021 are inserted into the groove at the top of the support frame 1. A sealing plate 4011 is fixed to one side of the device box 401 using an angle iron 4012, and the motor 6 is fixed to the outer wall of the sealing plate 4011. T-shaped sliders are provided on the contact surfaces of the two tooth plates 403 and the device box 401. The T-shaped slider cooperates with the slot of the device box 401, so that the tooth plate 403 slides in the device box 401.

[0029] As mentioned above, the fixing blocks 1021 at both ends of the upper guide rod 102 are designed to be square, which can effectively prevent the upper guide rod 102 from rotating on the top of the heat exchange plate 3, thereby affecting the subsequent fixation. The fixing blocks 1021 are stuck in the groove at the top of the support frame 1, which increases the stability of the placement of the upper guide rod 102. The sealing plate 4011 is fixed to one side of the device box 401 using angle iron 4012, which is convenient for disassembly and maintenance of the components inside the device box 401. The tooth plate 403 is slidably connected to the device box 401 using a T-shaped slider, which improves the safety of the device and prevents the tooth plate 403 from falling off.

[0030] The guides at both ends of the heat exchange plate 3 are designed with bumps, the inner side of the support frame 1 is provided with grooves, the bumps of the heat exchange plate 3 match the grooves of the support frame 1, and a sealing ring 201 is provided at the contact part of one end of the guide pipe 2 with the heat exchange plate 3.

[0031] As mentioned above, the guide parts at both ends of the heat exchange plate 3 are designed to be in the shape of convex blocks that fit into the grooves of the support frame 1, so that the parts fit more tightly, and a sealing ring 201 is placed at the contact part between the guide pipe 2 and the heat exchange plate 3, which can enhance the fluid transport effect.

[0032] The collecting device 5 includes a collecting box 501 placed on a supporting plate of the supporting frame 1, a filter screen 502 is arranged inside the collecting box 501, a locking block 103 is arranged at the bottom of the supporting frame 1, one end of the locking block 103 is rotatably connected to the supporting frame 1, and the other end can be fixed to the supporting plate with bolts, the locking block 103 fits with the collecting box 501, and the fixing effect is achieved after the two ends are fixed.

[0033] As mentioned above, the collecting box 501 is placed under the heat exchange plate 3 to collect the fluid dripping during use and maintenance, and the filter screen 502 is arranged inside to filter the impurities. The locking block 103 is used to fix the placed collecting box 501 to prevent the collecting box 501 from moving during operation. When the collecting box 501 needs to be removed, only the bottom bolt needs to be removed, and the locking block 103 will be affected by gravity and hang on the supporting frame 1.

[0034] Working principle: In this case, when in use, the starting motor 6 drives the gear 402 to rotate, and the gear 402 rotates to drive the two tooth plates 403 to move, so that the block 405 on the top of the tooth plate 403 moves inward. When the block 405 contacts the upper guide rod 102, the block 405 is squeezed and the spring 404 is compressed. When the block 405 moves to the groove on the fixing block 1021 on the upper guide rod 102, the block 405 is ejected by the spring 404 and inserted into the groove. The device stops moving to fix the upper guide rod 102. When it is necessary to maintain the heat exchange plate 3, the starting motor 6 drives the gear 402 to rotate in the opposite direction. After the block 405 leaves the upper guide rod 102, the upper guide rod 102 is taken out, and the heat exchange plate 3 can be taken out from the top for maintenance. The two ends of the block 405 are designed as arc surfaces, which can make it easier for the block 405 to move up and down during the movement. During the operation of the heat exchanger, the fluid passes through the heat exchange plate 3 from the guide tube 2 to form a loop. A collection box 501 is placed under the heat exchange plate 3. The locking block 103 is used to fix the placed collection box 501. The collection box 501 upgrades the fluid dripping during use and maintenance, and the filter screen 502 is arranged inside to filter impurities.
