The dryer heats the material to vaporize and escape the moisture, so as to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. This device is the heat utilization device of the gas discharged from the dryer.

[0003] When the dryer recycling device is in use, if the gas from the dryer enters the device at high speed, it can easily impact the internal components. At the same time, if the flow rate is too fast, it can easily affect the heat utilization effect.

[0004] Therefore, a dryer recycling and reuse device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a dryer recycling and reuse device to solve the problem mentioned in the background art that the flow rate of the dryer exhaust gas entering the device is too fast, making it inconvenient for heat utilization.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dryer recycling device, comprising a heat exchange tank, an inlet pipe, and an exhaust pipe. A rotary heat utilization component is installed at the bottom of the heat exchange tank. The rotary heat utilization component includes a positioning platform, a support platform, a drain pipe, a rotating cylinder, heat sinks, a flow channel, and a docking platform. The positioning platform is located at the bottom of the heat exchange tank. A support platform is fixed to the outer wall of the positioning platform. The front end of the support platform is fixedly connected to the inner wall of the heat exchange tank. A drain pipe is installed at the bottom of the positioning platform, extending to the outside of the heat exchange tank on its right side. A rotating cylinder is movably installed at the top of the positioning platform. Heat sinks are fixed to the outer wall of the rotating cylinder. A flow channel is provided inside the rotating cylinder. A docking platform is installed at the center of the top of the rotating cylinder.

[0007] As a further technical solution of this utility model, a number of heat sinks are fixed on the outer wall of the rotating cylinder, and the number of heat sinks are arranged in a ring.

[0008] As a further technical solution of this utility model, several flow channels are provided inside the rotating cylinder, and the several flow channels are symmetrically distributed.

[0009] As a further technical solution of this utility model, a support frame is fixed at the top of the inner wall of the heat exchange tank, a heat exchange tube is installed at the top of the support frame, a water inlet pipe is installed at the top of the left side of the heat exchange tube, the left side of the water inlet pipe extends to the outside of the heat exchange tank, and a connecting pipe is installed at the bottom of the heat exchange tube, the bottom of the connecting pipe extends to the inside of the docking platform.

[0010] As a further technical solution of this utility model, an air inlet pipe is installed on the left side of the heat exchange tank, and an exhaust pipe is installed on the top of the heat exchange tank.

[0011] As a further technical solution of this utility model, a support foot is installed at the bottom of the heat exchange tank, and a drain pipe is installed at the center of the bottom of the heat exchange tank.

[0012] As a further technical solution of this utility model, an installation platform is fixed to the inner wall of the air intake pipe, an installation groove is provided inside the installation platform, a filter ring is provided inside the installation groove, and a filter screen is installed inside the filter ring.

[0013] As a further technical solution of this utility model, the mounting groove is provided with internal threads, and the surface of the filter ring is provided with external threads.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a rotating cylinder, the positioning platform is suspended at the bottom of the heat exchange tank with the assistance of multiple sets of support platforms. The rotating cylinder is movably installed on the top of the positioning platform for use. The internal flow channel is connected to the positioning platform and the drain pipe at the bottom. When the gas enters along the positioning platform, it impacts the surface of the rotating cylinder. The rotating cylinder can rotate due to the impact, which slows down the flow rate of the gas after it enters. This realizes the flow rate control function inside the dryer recycling device.

[0015] By installing heat exchange tubes located at the top of the heat exchange tank, with the bottom connecting pipes connecting to the docking platform at the top of the rotating cylinder and communicating with the flow channels inside the rotating cylinder, the heat exchange tubes, located at the top of the heat exchange tank, allow the gas to contact the heat exchange tubes as it rises. When the liquid flows inside the heat exchange tubes, the heat from the gas can be transferred to the liquid inside the heat exchange tubes, assisting in the further recovery and utilization of the gas heat and enhancing the effectiveness of the dryer's heat recovery and reuse device.

[0016] By incorporating filter rings and filter screens, the filter rings are threaded into the mounting grooves inside the mounting platform and located inside the inlet pipe. When gas enters the heat exchange tank through the inlet pipe, the filter rings and filter screens inside the inlet pipe assist in filtering the gas, thus realizing the auxiliary filtration function at the inlet pipe of the dryer's recycling and reuse device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a dryer recycling device, including a heat exchange tank 1, an air inlet pipe 13, and an exhaust pipe 14. A rotary heat utilization component is provided at the bottom of the heat exchange tank 1. The rotary heat utilization component includes a positioning platform 2, a support platform 3, a drain pipe 4, a rotating cylinder 5, heat sinks 6, flow channels 7, and a docking platform 8. The positioning platform 2 is provided at the bottom of the heat exchange tank 1. The support platform 3 is fixed to the outer wall of the positioning platform 2. The front end of the support platform 3 is fixedly connected to the inner wall of the heat exchange tank 1. The drain pipe 4 is installed at the bottom of the positioning platform 2. The drain pipe 4 extends to the outer side of the heat exchange tank 1 on the right side. The rotating cylinder 5 is movably installed at the top of the positioning platform 2. Heat sinks 6 are fixed to the outer wall of the rotating cylinder 5. Several heat sinks 6 are fixed to the outer wall of the rotating cylinder 5. The several heat sinks 6 are arranged in a ring. Flow channels 7 are provided inside the rotating cylinder 5. Several flow channels 7 are arranged inside the rotating cylinder 5. The several flow channels 7 are arranged symmetrically. The docking platform 8 is installed at the center of the top of the rotating cylinder 5.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, when the gas enters through the positioning platform 2, it impacts the surface of the rotating cylinder 5. The rotating cylinder 5 rotates due to the impact, which slows down the flow rate of the gas after it enters. At the same time, the flow channel 7 inside the rotating cylinder 5 is connected to the positioning platform 2 and the drain pipe 4 at the bottom. When the gas comes into contact with the outside of the rotating cylinder 5, it can transfer heat to the internal flow channel 7 with the assistance of the heat sink 6. When the liquid flows through the flow channel 7, it can transfer heat.

[0026] A support frame 9 is fixed to the top of the inner wall of the heat exchange tank 1. A heat exchange tube 10 is installed at the top of the support frame 9. A water inlet pipe 11 is installed at the top of the left side of the heat exchange tube 10. The left side of the water inlet pipe 11 extends to the outside of the heat exchange tank 1. A connecting pipe 12 is installed at the bottom of the heat exchange tube 10. The bottom of the connecting pipe 12 extends to the inside of the docking platform 8.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, during use, when the gas moves upward and comes into contact with the heat exchange tube 10, the liquid can exchange heat with the gas as it flows along the heat exchange tube 10. After that, the liquid can flow into the interior of the rotating cylinder 5 along the connecting tube 12.

[0028] An air inlet pipe 13 is installed on the left side of the heat exchange tank 1, an exhaust pipe 14 is installed on the top of the heat exchange tank 1, a support foot 15 is installed on the bottom of the heat exchange tank 1, a drain pipe 16 is installed at the center of the bottom of the heat exchange tank 1, an installation platform 17 is fixed on the inner wall of the air inlet pipe 13, an installation groove 18 is provided inside the installation platform 17, a filter ring 19 is provided inside the installation groove 18, an internal thread is provided inside the installation groove 18, an external thread is provided on the surface of the filter ring 19, and a filter screen 20 is installed inside the filter ring 19.

[0029] Specifically, such as Figure 1 and Figure 5 As shown, during use, as the gas enters the heat exchange tank 1 through the inlet pipe 13, the filter ring 19 and filter screen 20 located inside the inlet pipe 13 can assist in filtering the incoming gas and reduce the amount of impurities entering the heat exchange tank 1.

[0030] Working principle: During use, the high-temperature gas discharged from the dryer enters the heat exchange tank 1 through the inlet pipe 13. The filter ring 19 and filter screen 20 located inside the inlet pipe 13 can assist in filtering the incoming gas, reducing the amount of impurities entering the heat exchange tank 1. When the flue gas enters the heat exchange tank 1, it impacts the surface of the rotating cylinder 5, causing the rotating cylinder 5 to rotate due to the impact, slowing down the flow rate of the gas after it enters. Then, it moves upward and is finally discharged through the exhaust pipe 14. During this process, the liquid enters the heat exchange tube 10 through the water inlet pipe 11. The heat exchange tube 10 absorbs the heat from the upper part of the gas. Then, the liquid enters the flow channel 7 inside the rotating cylinder 5 through the connecting pipe 12. When the gas comes into contact with the outside of the rotating cylinder 5, with the assistance of the heat sink 6, it can transfer heat to the internal flow channel 7. After exchanging heat with the liquid inside the flow channel 7, the liquid is finally discharged to the outside through the support platform 3 and drain pipe 4 on the bottom side for use.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
