Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a waste heat recovery plate heat exchange module. Background Technology

[0002] Waste heat recovery plate heat exchanger modules are a type of high-efficiency energy recovery system. They use plate heat exchangers to convert waste heat generated in industrial processes into reusable thermal energy. In daily use, it has been found that plate heat exchangers, as an important component of air compressor waste heat recovery devices, are often used for heat recovery. However, when the entire plate heat exchanger is connected to the pipeline, the pipeline is long and the plate heat exchanger is heavy, which can easily lead to misalignment of the connection position, making it inconvenient to quickly connect the entire plate heat exchanger to the pipeline.

[0003] The utility model patent disclosed in CN220539808U (hereinafter referred to as prior art D1) discloses a waste heat recovery and utilization device for air compressors. This prior art device utilizes a servo motor on the base plate to drive the rotation between a gear and a rack, thereby causing the rack to move the sliding frame and limit the movement of the heat exchanger on the sliding frame. However, this device has certain shortcomings. First, after moving the entire sliding frame to the designated position via the gear and rack drive, a screw on the limiting block is needed to press and fix the entire sliding frame and heat exchanger. Each movement of the sliding frame requires tightening the screw for pressing and fixing, making the operation cumbersome. Second, the entire device needs to be moved and transported, which undoubtedly increases the workload and intensity, resulting in low work efficiency. Therefore, we designed a waste heat recovery plate heat exchange module to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a waste heat recovery plate heat exchange module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waste heat recovery plate heat exchange module includes heat exchange plates disposed inside a heat exchange frame. Two sliding frames are fixedly engaged at the bottom of the heat exchange frame. Each sliding frame has a T-shaped groove at its bottom, extending horizontally. A T-shaped base plate slides within the T-shaped groove, and a support plate is located at the bottom of the T-shaped base plate. A movable base plate is connected to the bottom of both support plates. An opening is formed at each of the four corners of the top of the movable base plate, and a fixing box is located at the top of each opening. Four fixing boxes are arranged in pairs, with two pairs of fixing boxes symmetrically distributed on the left and right sides of the heat exchange frame. The internal sliding surfaces of the fixing boxes... The system includes a lifting block with a movable wheel at its bottom and an adjustment assembly at its top. Two sliding frames are symmetrically positioned at opposite ends of their sides, with each first movable block threaded onto the outside of a threaded rod. The threaded rod is rotatably positioned between two first fixed blocks. The right end of the threaded rod passes through a first fixed block and is connected to a pulley. The two pulleys are connected via a belt drive. One support plate has an L-shaped mounting bracket on its right side surface, and a drive motor is located on the outer surface of the L-shaped mounting bracket. The output shaft of the drive motor passes through the L-shaped mounting bracket and is connected to an adjacent pulley.

[0007] As a preferred embodiment of this utility model: the adjustment assembly includes two U-shaped mounting brackets fixedly mounted on the top of the movable base plate. A threaded column is rotatably provided between the inner top wall of the U-shaped mounting bracket and the top surface of the movable base plate. A through groove is symmetrically opened on the side of the two fixed boxes of each group that are close to each other. A connecting block is provided on the top of the lifting block. The ends of the two connecting blocks that are close to each other extend to the outside of the fixed box through the through groove and are connected to the same connecting plate. The connecting plate is threaded onto the outside of the threaded column. The top end of the threaded column passes through to the top of the U-shaped mounting bracket and is connected to a rotating handle. The rotating handle is rotatably mounted on the top of the U-shaped mounting bracket.

[0008] As a further preferred embodiment of this utility model: two vertical rods are symmetrically provided on the front and rear sides of the U-shaped mounting bracket, the vertical rods are fixedly installed on the top of the movable base plate, and the connecting plate is slidably sleeved on the outside of the vertical rods.

[0009] As a further preferred embodiment of this utility model: a second moving block is symmetrically provided at one end of the two sliding frames that are close to each other. The second moving block is slidably sleeved on the outside of the guide rod. The guide rod is fixedly disposed between the two second fixed blocks. The length direction of the guide rod is parallel to the length direction of the threaded rod.

[0010] As a further preferred embodiment of this utility model, the thickness of the lifting block is equal to the thickness of the moving base plate.

[0011] As a further preferred embodiment of this utility model: the length direction of the threaded rod is parallel to the sliding direction of the sliding frame.

[0012] As a further preferred embodiment of this utility model: the two U-shaped mounting brackets are symmetrically distributed on the left and right sides of the heat exchange frame, and the two fixing boxes of each group are symmetrically distributed on the front and rear sides of the U-shaped mounting bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When this device is in use, the drive motor can drive the pulley to rotate, which in turn drives another pulley to rotate, thereby driving the two threaded rods to rotate, which in turn drives the two first moving blocks to move, and then drives the two sliding frames to move. When the sliding frames move to the designated position, the drive motor can be stopped. The position of the sliding frames is fixed and stable, eliminating the need for additional structures and operations to limit and fix them as required by traditional devices. The operation is simpler and more flexible, and the movement process only requires one drive motor, which saves costs.

[0015] 2. When the entire device needs to be moved, the operator rotates the threaded column by turning the handle, which in turn moves the connecting plate downwards. The two ends of the connecting plate can move the lifting blocks downwards via connecting blocks, which in turn moves the corresponding moving wheels downwards, so that the moving wheels extend to the bottom of the opening and contact the ground. This facilitates the movement of the entire device without the need for manual handling, saving time and effort and improving work efficiency. When the device is moved to the appropriate position, the handle can be turned in the opposite direction. Similarly, the lifting blocks and moving wheels can be moved upwards together, so that the moving wheels are completely retracted into the opening. At this point, the bottom surface of the moving base plate is in complete contact with the ground, ensuring the stability of the entire device during use. This greatly improves the practicality of the device and is worth promoting. Attached Figure Description

[0024] Please see Figure 1-5In this embodiment of the utility model, the waste heat recovery plate heat exchange module includes heat exchange plates disposed inside the heat exchange frame 3. The structure of the heat exchange frame 3 is existing technology. The bottom of the frame 3 is improved. The structure of other parts of the heat exchange frame 3 is not innovative in this application, so it will not be described in detail. It is also not shown in detail in the figure. See reference document D1 (authorization announcement number CN220539808U) for details. The bottom of the heat exchange frame 3 is provided with two sliding frames 5 fixedly connected. The bottom of the sliding frame 5 is provided with a T-shaped groove. The T-shaped groove is arranged through the left and right sides. A T-shaped base plate 14 adapted to it is slidably disposed in the T-shaped groove. The bottom of the T-shaped base plate 14 is provided with a support plate 7. The bottom of the two support plates 7 is connected to a movable base plate 1. The top four corners of the movable base plate 1 are provided with through openings 25. The top of the through openings 25 is provided with a fixing box 2. The four fixing boxes 2 are arranged in pairs, and the two sets of fixing boxes are arranged in pairs. 2 are symmetrically distributed on the left and right sides of the heat exchange frame 3. The inside of the fixed box 2 is provided with a lifting block 26. The bottom of the lifting block 26 is provided with a moving wheel 9. The top of the movable base plate 1 is provided with an adjustment component for controlling the lifting of the moving wheel 9. The two sliding frames 5 are symmetrically provided with a first moving block 19 on one side away from each other. The first moving block 19 is threaded on the outside of the threaded rod 6. The threaded rod 6 is rotatably set between the two first fixed blocks 18. The length direction of the threaded rod 6 is parallel to the sliding direction of the sliding frame 5. The right end of the threaded rod 6 passes through the first fixed block 18 and is connected to a pulley 17. The two pulleys 17 are connected by a belt 13. The right side surface of one of the support plates 7 is provided with an L-shaped mounting bracket 16. The outer surface of the L-shaped mounting bracket 16 is provided with a drive motor 15. The output shaft of the drive motor 15 passes through the L-shaped mounting bracket 16 and is connected to the adjacent pulley 17.

[0025] The adjustment assembly includes two U-shaped mounting brackets 8 fixedly mounted on the top of the movable base plate 1. Threaded columns 21 are rotatably provided between the inner top wall of the U-shaped mounting brackets 8 and the top surface of the movable base plate 1. The two U-shaped mounting brackets 8 are symmetrically distributed on the left and right sides of the heat exchange frame 3. Two fixed boxes 2 in each group are symmetrically distributed on the front and rear sides of the U-shaped mounting brackets 8. Through slots 23 are symmetrically opened on the sides of the two fixed boxes 2 that are close to each other. A connecting block 20 is provided on the top of the lifting block 26. The ends of the two connecting blocks 20 that are close to each other extend to the outside of the fixed box 2 through the through slots 23 and are connected to the same connecting plate 22. The connecting plate 22 is threaded onto the outside of the threaded column 21. The top end of the threaded column 21 extends through to the top of the U-shaped mounting bracket 8 and is connected to a rotating handle 4. The rotating handle 4 is rotatably mounted on the top of the U-shaped mounting bracket 8.

[0026] Two vertical rods 24 are symmetrically arranged on the front and rear sides of the U-shaped mounting bracket 8. The vertical rods 24 are fixedly set on the top of the movable base plate 1, and the connecting plate 22 is slidably sleeved on the outside of the vertical rods 24. The vertical rods 24 serve as guides and stabilizers for the lifting and lowering of the connecting plate 22, thereby improving the stability of the lifting and lowering process of the movable wheel 9.

[0027] Two sliding frames 5 are symmetrically provided with second moving blocks 10 on one side of their adjacent sides. The second moving blocks 10 are slidably sleeved on the outside of the guide rod 11. The guide rod 11 is fixedly set between two second fixed blocks 12. The length direction of the guide rod 11 is parallel to the length direction of the threaded rod 6. Through the sliding connection between the second fixed blocks 12 and the guide rod 11, the movement of the sliding frames 5 is guided and stabilized.

[0028] The thickness of the lifting block 26 is equal to the thickness of the movable base plate 1. When the connecting plate 22 descends to abut against the top surface of the movable base plate 1, the lifting block 26 is just fully embedded in the opening 25, and the movable wheel 9 is just fully extended to the bottom of the opening 25, which facilitates the movement of the entire device.

[0029] Specifically, when this device is in use, the drive motor 15 can drive the pulley 17 to rotate, which in turn drives another pulley 17 to rotate via the belt 13, thereby driving the two threaded rods 6 to rotate, which in turn drives the two first moving blocks 19 to move, and then drives the two sliding frames 5 to move. When the sliding frames 5 move to the designated position, the drive motor 15 can be stopped. The position of the sliding frames 5 is fixed and stable, eliminating the need for additional structures and operations to limit and fix them as required in traditional devices. The operation is simpler and more flexible, and the movement process only requires one drive motor, which saves costs.

[0030] Furthermore, when the entire device needs to be moved, the operator can rotate the threaded column 21 by turning the handle 4, which in turn moves the connecting plate 22 downward. The two ends of the connecting plate 22 can move the lifting block 26 downward through the connecting block 20, which in turn moves the corresponding moving wheel 9 downward, so that the moving wheel 9 extends to the bottom of the opening 25. Even if the moving wheel 9 contacts the ground, it facilitates the movement of the entire device without the need for manual handling, saving time and effort and improving work efficiency. When the device is moved to the appropriate position, the handle 4 can be rotated in the opposite direction. Similarly, the lifting block 26 and the moving wheel 9 can be controlled to move upward together, so that the moving wheel 9 is completely retracted into the opening 25. At this time, the bottom surface of the moving base plate 1 is in complete contact with the bottom surface, ensuring the stability of the entire device during use and greatly improving the practicality of the device. It is worth promoting and using.

[0031] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
