[0020] Embodiment 1

[0021] A fully automated intelligent control waste heat recovery device described in this embodiment, as shown in Figure 1 、 Figure 2 and Figure 4 shown, the figure includes a waste heat recovery device 11. An adjusting mechanism for adjusting the air intake volume is provided at the air inlet of the waste heat recovery device 11. An electronic actuator 14 for controlling its opening and closing is electrically connected to the adjusting mechanism. A temperature sensor 12 is provided at the air outlet of the waste heat recovery device 11. A controller 13 is electrically connected between the electronic actuator 14 and the temperature sensor 12. The controller 13 is used to receive and process the signals fed back by the temperature sensor 12 and transmit control signals to the electronic actuator 14; as shown in Figure 3 and Figure 5As shown, during use, the temperature sensor 12 feeds back a signal to the controller 13, and the controller 13 issues a control signal to the electronic actuator 14. The electronic actuator 14 controls the adjustment mechanism to adjust the air intake volume of the waste heat recovery device 11, so as to adjust the air intake volume according to the real-time ambient temperature and improve applicability. The electronic actuator 14 is also known as an electric actuator or an electric actuator mechanism. It is a controller that can generate torque, speed or displacement output, and realizes automatic control through an electronic control system. It is usually composed of components such as a motor, a reduction mechanism linked to the motor, a stroke sensor, and a control chip. The motor serves as the power source, the reduction mechanism is used to adjust the output speed and increase the output torque, the stroke sensor is used to monitor the position of the actuator in real time, and the control chip is responsible for receiving instructions and controlling the entire execution process. The electronic actuator can usually respond to instructions within a very short time, has a fast execution speed, and can achieve high-precision position control. Among them, the controller 13 is electrically connected to the electronic actuator 14 for executing the control signal, and the electronic actuator 14 is electrically connected to the adjustment mechanism to improve the accuracy of signal response, facilitate automatic adjustment of the air intake volume, adjust the air intake volume according to requirements, meet the requirements of various working conditions, and has the effect of improving applicability. The adjustment mechanism includes an outer tube 8 detachably fixed to the air inlet of the waste heat recovery device 11. Flange plates 9 for connecting the air inlet of the waste heat recovery device 11 and the external gas pipeline are fixed at both ends of the outer tube 8. Align the flange plates 9 at both ends of the outer tube 8 with the flange plates on the air inlet of the waste heat recovery device 11 and the external gas pipeline, and connect the two ends of the outer tube 8 to the air inlet of the waste heat recovery device 11 and the external gas pipeline respectively through bolts and nuts, so that the staff can disassemble and assemble the outer tube 8, which is convenient for subsequent cleaning or maintenance and replacement.

[0022] Two discs 5 are independently inserted into the outer tube 8 in a parallel and aligned manner and are in close contact with each other. The close contact of the discs 5 can prevent excessive gas from leaking through the gap between the two.

[0023] A number of ventilation holes are evenly arranged on the two discs 5 along the circumferential direction. In this embodiment, six ventilation holes are arranged on each disc 5 at equal intervals along the circumferential direction. The number of ventilation holes on each disc 5 can be set according to actual needs. The ventilation holes are in an isosceles triangle structure, and the tips of all the isosceles triangle ventilation holes face the center of the disc 5. The triangular ventilation holes can greatly improve the utilization rate of the disc 5 and allow the gas to pass through the outer tube 8 in the largest amount. Of course, the ventilation holes can also be of other shapes such as circular or rectangular.

[0024] One of the disks 5 is detachably fixed to the inner tube wall of the outer tube 8. An inner tube 7 is independently inserted through the outer tube 8. There is a gap between the inner tube 7 and the inner tube wall of the outer tube 8, so that the inner tube 7 can enter and exit the outer tube 8 from one end of the outer tube 8. One end of the inner tube 7 is fixed to the disk 5 that does not fix the arc-shaped rack 3, so that the inner tube 7 can drive the disk 5 to enter and exit the outer tube 8 when entering and exiting the outer tube 8. A number of positioning blocks 10 are fixed to the other end of the inner tube 7. A number of positioning grooves are opened on the end face of one end of the outer tube 8 for independently engaging all the positioning blocks 10. In this embodiment, the number of the positioning blocks 10 is two. Of course, the number of the positioning blocks 10 can be selected according to the actual use situation. The two positioning blocks 10 are evenly distributed on one end of the inner tube 7. When the inner tube 7 is completely inserted into the outer tube 8, the two positioning blocks 10 will be respectively engaged in the corresponding positioning grooves, and the positioning blocks 10 are positioned through the positioning grooves to prevent the inner tube 7 from rotating or moving into the inner part of the outer tube 8. A perforation is opened on each positioning block 10, a threaded hole is opened at the bottom of each positioning groove, a screw is inserted through each perforation, and each screw is in threaded cooperation with the threaded hole in the corresponding positioning groove. After each positioning block 10 is engaged in the corresponding positioning groove, the positioning block 10 is locked in the corresponding positioning groove by the screw, so as to prevent the inner tube 7 from being pulled out of the outer tube 8. And by pulling out the inner tube 7 from the outer tube 8, it is convenient for the staff to replace or repair the two disks 5 or the inner tube 7, and at the same time, it is also convenient for the staff to clean the inside of the outer tube 8, the inside of the inner tube 7 and the two disks 5.

[0025] The other disk 5 is rotatably mounted on the disk 5 fixed to the inner tube wall of the outer tube 8. A mounting shaft 6 is fixed to the disk 5 that does not fix the arc-shaped rack 3. A through hole for independently inserting the mounting shaft 6 is opened on the other disk 5. A positioning screw is inserted through one end of the mounting shaft 6 passing through the through hole. The mounting shaft 6 is fixed at the center of the side wall of the disk 5. There is a gap between the through hole and the mounting shaft 6, so that the disk 5 can rotate around the mounting shaft 6 as the center. The disk 5 can be blocked by the hexagonal head end of the positioning screw to prevent the disk 5 from falling off the mounting shaft 6.

[0026] An arc-shaped rack 3 is fixed on the side wall of the rotatable disk 5. A motor 1 electrically connected to an electronic actuator 14 is installed on the outer side wall of the outer tube 8. A gear 2 meshing with the arc-shaped rack 3 is sleeved on the output end of the motor 1. A through hole for the gear 2 to pass through is formed in the tube wall of the outer tube 8. The electronic actuator 14 controls the opening and closing and the rotation direction of the motor 1. The motor 1 drives the gear 2 to rotate. The gear 2 drives the arc-shaped rack 3 to rotate by an angle with the center point of the disk 5 as the center of the circle. The arc-shaped rack 3 drives the disk 5 to rotate, so that all the ventilation holes on the disk 5 are gradually misaligned with the ventilation holes on another disk 5. The air intake volume of the gas is adjusted according to the misalignment degree of the ventilation holes on the two disks 5. When the ventilation holes on the two disks 5 are completely misaligned, the outer tube 8 cannot pass gas anymore. When the ventilation holes on the two disks 5 are completely aligned, it is the maximum air intake volume. A retaining ring 4 for positioning the rotatable disk 5 is fixed inside the outer tube 8. The retaining ring 4 is fixed at one end inside the outer tube 8 where the inner tube 7 is not inserted. When installing the rotatable disk 5, the retaining ring 4 can block and position the disk 5 to prevent the rotatable disk 5 from moving excessively towards the direction of the retaining ring 4 and affecting the meshing of the arc-shaped rack 3 and the gear 2.

[0027] During the actual use process, the end of the inner tube 7 with two disks 5 installed is completely inserted into the outer tube 8. The two positioning blocks 10 are respectively engaged in the corresponding positioning grooves, and all the positioning blocks 10 are locked in the corresponding positioning grooves by screws, thereby locking the inner tube 7 to prevent the inner tube 7 from rotating or moving. The flange plates 9 at both ends of the outer tube 8 are aligned with the flange plates at the air inlet of the waste heat recovery device 11 and on the external gas pipeline, and the two ends of the outer tube 8 are respectively connected to the air inlet of the waste heat recovery device 11 and the external gas pipeline through bolts and nuts. During the continuous heat exchange process, the temperature sensor 12 senses the temperature of the air outlet after heat exchange and feeds it back to the controller 13. The controller 13 analyzes and processes the data collected by the temperature sensor 12, and issues corresponding control signals to the electronic actuator 14 according to the scene temperature requirements. The electronic actuator 14 controls the motor 1 to start, so that the motor 1 drives the gear 2 to rotate, causing the gear 2 to drive the arc-shaped rack 3 to rotate by an angle with the center point of the disk 5 as the center of the circle. The arc-shaped rack 3 drives the disk 5 to rotate, so that all the ventilation holes on the disk 5 are gradually misaligned with the ventilation holes on another disk 5. The air intake volume is adjusted according to the misalignment degree of the ventilation holes on the two disks 5, thereby adjusting the air intake volume according to the requirements and meeting the requirements of various working conditions, having the effect of improving applicability.
