Description

Technical Field

[0001] This utility model relates to the field of flow guide technology, and in particular to a low-resistance waste heat recovery flow guide. Background Technology

[0002] During industrial production, energy conversion, and equipment operation, a large amount of waste heat is emitted into the environment along with waste gas, waste liquid, and other media, which not only causes energy waste but also exacerbates thermal pollution problems. Therefore, a waste heat recovery diverter is needed to recover and utilize waste heat.

[0003] Currently, one type of waste heat recovery diverter in the existing technology has heat exchange fins that are inconvenient to install and remove. In traditional devices, the heat exchange fins are either welded to the entire device or installed and removed separately with screws. However, the screw installation and removal method is time-consuming and labor-intensive, with significant limitations and poor practicality. In addition, one type of waste heat recovery diverter in the existing technology suffers from a decrease in heat exchange efficiency due to the high resistance of the internal fluid. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of inconvenient installation and removal of heat exchange plates used for waste heat recovery in the prior art. In traditional devices, heat exchange plates are either welded to the whole device or installed and removed separately by screws. The screw installation and removal method is time-consuming and labor-intensive, with great limitations, and the heat exchange efficiency is reduced due to the high resistance of the internal fluid. Therefore, a low-resistance waste heat recovery guide is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-resistance waste heat recovery guide includes a body, with fixed frames at both ends of the body, and multiple heat exchange plates installed in each of the two fixed frames. The opposite ends of the two sets of heat exchange plates pass through one side of the body and are located inside the body. Support plates are provided on both the left and right sides of the body, and locking blocks are fixed at the opposite ends of the two support plates. The two locking blocks are engaged in the two fixed frames. The body is provided with a drive structure for driving the two support plates to move in opposite directions.

[0006] Preferably, the drive structure includes a motor installed in the machine body, the output end of the motor is fixed with a bidirectional screw, both ends of the outer wall of the bidirectional screw are threaded with movable plates, both ends of the two movable plates are slidably connected with limit posts, one opposite end of the two movable plates is fixed with a connecting block, and one opposite end of the two connecting blocks passes through the machine body and is fixed to two support plates respectively.

[0007] Preferably, the bottom of the machine body has a bottom opening, a stop block is engaged in the bottom opening, a connecting plate is fixed to the bottom of the stop block, and the connecting plate is fixed to the machine body by bolts.

[0008] Preferably, the machine body has an inner cavity, and the opposite ends of the two sets of heat exchange plates are both located in the inner cavity, and one end of each set of heat exchange plates has an arc-shaped opening.

[0009] Preferably, each of the four corners of the bottom of the machine body is fixed with a support leg, and each of the front and rear ends of the machine body is fixed with a connecting pipe. Each of the two connecting pipes has a mounting plate fixed on its outer wall, and each of the two mounting plates has multiple mounting holes.

[0010] Preferably, the end of the bidirectional screw away from the motor is rotatably connected to the machine body, both ends of the limiting post are fixed to the machine body, and the opposite ends of the two fixing frames are provided with slots that match the locking blocks.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the operation of the motor drives the bidirectional screw to rotate, causing the two moving plates to move towards or away from each other under the limitation of the limiting post. This, in turn, causes the two support plates connected by the two connecting blocks to move towards or away from each other. When the two support plates move towards each other, they cause the two locking blocks to engage in the slots opened at the opposite ends of the two fixed frames, thus limiting the position of the two fixed frames and achieving the effect of installing the two fixed frames. When the two support plates move in opposite directions, they can cause the two locking blocks to disengage from the slots. At this time, the user can directly remove the entire fixed frame, which is convenient for maintenance and replacement of the heat exchange fins installed inside. This enhances its practicality. In addition, the heat exchange fins of this device are designed with arc-shaped openings, which guide the fluid entering the inner cavity to flow stably, avoiding turbulence and achieving a low-resistance effect, further enhancing its practicality.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a low-resistance waste heat recovery guide, including a body 1. The left and right ends of the body 1 are provided with fixed frames 5. Multiple heat exchange plates 6 are installed in each of the two fixed frames 5. The opposite ends of the two sets of heat exchange plates 6 pass through one side of the body 1 and are located inside the body 1. The left and right sides of the body 1 are provided with support plates 9. The opposite ends of the two support plates 9 are fixed with locking blocks 10. The two locking blocks 10 are locked in the two fixed frames 5. The body 1 is provided with a drive structure 12 for driving the two support plates 9 to move in opposite directions.

[0021] The effect achieved by the entire embodiment 1 is that, through the operation of the drive structure 12, the two support plates 9 can be driven to move towards or away from each other. When the two support plates 9 move towards each other, they will drive the two locking blocks 10 to engage in the locking slots 11 opened at the opposite ends of the two fixed frames 5, thereby limiting the position of the two fixed frames 5 and achieving the effect of installing the two fixed frames 5. When the two support plates 9 move in opposite directions, they can drive the two locking blocks 10 to disengage from the locking slots 11. At this time, the user can directly remove the entire fixed frame 5, which is convenient for the heat exchange fins 6 installed inside to be repaired and replaced, making it more practical.

[0022] Example 2, as Figure 1-4As shown, the drive structure 12 includes a motor 1201 installed inside the body 1. A bidirectional screw 1202 is fixed to the output end of the motor 1201. Both ends of the outer wall of the bidirectional screw 1202 are threadedly connected to movable plates 1203. Limiting posts 1204 are slidably connected to both ends of the two movable plates 1203. Connecting blocks 1205 are fixed to the opposite ends of the two movable plates 1203. The opposite ends of the two connecting blocks 1205 penetrate the body 1 and are respectively fixed to two support plates 9. A bottom opening 17 is provided at the bottom end of the body 1. A stop block 13 is engaged in the bottom opening 17. A connecting plate 14 is fixed to the bottom end of the stop block 13. 14 is fixed to the body 1 by bolts 15. The body 1 has an inner cavity 7. The opposite ends of the two sets of heat exchange plates 6 are located in the inner cavity 7. The two sets of heat exchange plates 6 have arc-shaped openings 8 at one end. The four corners of the bottom of the body 1 are fixed with support legs 16. The front and rear ends of the body 1 are fixed with connecting pipes 2. The outer walls of the two connecting pipes 2 are fixed with mounting plates 3. The two mounting plates 3 have multiple mounting holes 4. The end of the bidirectional screw 1202 away from the motor 1201 is rotatably connected to the body 1. The two ends of the limiting post 1204 are fixed to the body 1. The opposite ends of the two fixing brackets 5 are provided with slots 11 that match the locking block 10.

[0023] The overall effect of embodiment 2 is that the heat exchange plate 6 of the device, through the setting of the arc-shaped opening 8, allows the fluid entering the inner cavity 7 to flow stably under the guidance of the arc-shaped opening 8, avoiding turbulence and achieving a low-resistance effect, thus enhancing its practicality. The operation of the motor 1201 drives the bidirectional screw 1202 to rotate, causing the two moving plates 1203 to move towards or in opposite directions under the limitation of the limiting post 1204. This, in turn, causes the two support plates 9 connected by the two connecting blocks 1205 to move towards or in opposite directions. When the two support plates 9 move towards each other, they cause the two locking blocks 10 to engage in the locking grooves 11 opened at the opposite ends of the two fixed frames 5, thereby securing the two fixed frames... The position of 5 is defined to achieve the effect of installing two fixed brackets 5. When the two support plates 9 move in opposite directions, they can drive the two locking blocks 10 to disengage from the slots 11. At this time, the user can directly remove the entire fixed bracket 5, which is convenient for maintenance and replacement of the heat exchange fins 6 installed inside. It is more practical. With the setting of the bottom opening 17, when it is necessary to clean the internal space of the body 1, the bolts 15 can be unscrewed to remove the connecting plate 14 and the stop block 13, and the bottom opening 17 at the bottom of the body 1 can be opened to facilitate the cleaning of the internal cavity 7 of the body 1. It is more practical. With the setting of two connecting pipes 2, mounting plate 3 and mounting hole 4, it is convenient to connect to the external circulation and conveying pipeline.

[0024] Working principle: When in use, the motor 1201 drives the bidirectional screw 1202 to rotate, causing the two moving plates 1203 to move towards or away from each other under the limit of the limiting post 1204. This causes the two support plates 9 connected by the two connecting blocks 1205 to move towards or away from each other. When the two support plates 9 move towards each other, they cause the two locking blocks 10 to engage in the slots 11 opened at opposite ends of the two fixed frames 5, thus limiting the position of the two fixed frames 5 and achieving the effect of installing the two fixed frames 5. When the two support plates 9 move in opposite directions, they can cause the two locking blocks 10 to disengage from the slots 11. At this time, the user can directly remove the entire fixed frame 5, which is convenient for maintenance and replacement of the heat exchange fins 6 installed inside, making it more practical. In addition, the heat exchange fins 6 of this device are designed with arc-shaped openings 8, which allow the fluid entering the inner cavity 7 to flow stably through the guidance of the arc-shaped openings 8, avoiding turbulence and achieving a low-resistance effect, making it more practical.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
