Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioning device for a pesticide processing plant. Background Technology

[0002] In the pesticide processing and production process, volatile organic compounds, dust, and high temperature and humidity are the main sources of air pollution in the factory. In the stages of pesticide synthesis, formulation, and filling, organic solvents, chemical intermediates, and adjuvants in the raw materials will continuously release toxic and harmful gases such as benzene series compounds and aldehydes. At the same time, the waste heat generated by the operation of production equipment and the dust particles formed by mixing and stirring are prone to accumulate in the closed factory. This means that the environment inside the factory not only threatens the respiratory health of the operators, but may also lead to excessive concentrations of flammable and explosive substances. Moreover, high temperature and humidity conditions will affect the stability of pesticide crystallization, granulation and other processes. Therefore, ventilation and air exchange inside the factory is one of the important measures for factory air conditioning. The common method is to install several non-powered ventilation balls on the roof of the factory. By taking advantage of the difference in air pressure and temperature inside and outside the factory, the gas inside the factory will naturally rise and be discharged through the ventilation balls, while outside air can be replenished into the factory through the factory doors, windows and other areas, thereby achieving the air conditioning of the factory. Although this structure is designed without a power source, it only has a few sloping vents on its outer wall. Therefore, it can only use the temperature or pressure difference between the inside and outside of the factory to drive the air flow and rotate the structure. It cannot rely on the external wind force of the factory, resulting in a slow exhaust speed, low air exchange efficiency and poor air conditioning effect. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an air conditioning device for a pesticide processing plant, the specific technical solution of which is as follows: An air conditioning device for a pesticide processing plant according to the present invention includes a rotating cylinder installed on the top of the plant. The rotating cylinder has a first chamber and an air guiding channel. Air in the plant flows into the first chamber through the air guiding channel. A plurality of mounting grooves are provided on the outer wall of the rotating cylinder. Each mounting groove has an air guiding groove communicating with the first chamber on its inner wall. Each of the mounting slots is provided with a column, and each column has an inclined fan blade on its outer wall. The column has an air port that communicates with the corresponding air guide slot, and the fan blade has an exhaust channel that communicates with the air port.

[0004] In the optimized implementation described above, both the horizontal and vertical cross-sectional shapes of the fan blades are arc-shaped, and the exhaust channel is arc-shaped.

[0005] In an improved embodiment, the opening of the exhaust channel is located on the inner wall of the end of the fan blade away from the rotating cylinder.

[0006] In an improved version of the above implementation, the column is rotatably mounted within the mounting groove.

[0008] In an optimized version of the above implementation, the inner wall of the second chamber is provided with threads, and a threaded ring is screwed onto the threads, with the adjusting disc rotatably sleeved on the threaded ring; An adjustment motor is installed in the second chamber. A drive shaft is installed at the output end of the adjustment motor. A drive wheel is installed on the drive shaft. The drive wheel is rotatably connected to the adjustment disc.

[0009] In an optimized version of the above implementation, a base is provided at the bottom of the rotating drum, the rotating drum is rotatably mounted on the base, and the bottom of the rotating drum and the base form a third chamber. A drive motor is provided in the third chamber, and a drive wheel is provided at the output end of the drive motor. The drive wheel is connected to the rotating drum in a transmission manner. The third chamber contains several battery packs electrically connected to the drive motor, and the base has an air guide hopper in the middle that communicates with the air guide channel. The air guide hopper is used to transport air from the factory to the first chamber.

[0010] In an improved version of the above implementation, the third chamber is equipped with a controller for adjusting the current between the drive motor and the battery pack.

[0011] The beneficial effects of this invention are as follows: By employing several tilted fan blades, the rotating cylinder and fan blades can be easily rotated by the airflow outside the factory, which helps to extract air from inside the factory, improve ventilation, and thus improve air conditioning efficiency.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0018] like Figures 1 to 6 As shown, an air conditioning device for a pesticide processing plant according to the present invention includes a rotating cylinder 1 installed on the top of the plant. The rotating cylinder 1 has a first chamber 2 and an air guiding channel 3. Air in the plant flows into the first chamber 2 through the air guiding channel 3. A plurality of mounting grooves 4 are provided on the outer wall of the rotating cylinder 1. Each mounting groove 4 has an air guiding groove 5 communicating with the first chamber 2 on its inner wall. Each mounting slot 4 is equipped with a column 6, and each column 6 has an inclined fan blade 7 on its outer wall. The column 6 has an air port 8 that communicates with the corresponding air guide slot 5, and the fan blade 7 has an exhaust channel 9 that communicates with the air port 8. In this invention, the rotating drum 1 can be rotatably installed on the top of the factory building, and the first chamber 2 inside the rotating drum 1 can be connected to the interior of the factory building through the air guide channel 3, thereby allowing air from inside the factory building to flow into the first chamber 2 through the air guide channel 3. The axis of the rotating drum 1 is vertical, and several columns 6 are distributed along the circumference of the rotating drum 1. Several mounting grooves 4 are correspondingly opened on the outer wall of the rotating drum 1. The columns 6 are installed in the mounting grooves 4, and the outer wall of the columns 6 is in contact with the inner wall of the mounting grooves 4. The air ports 8 on the columns 6 are connected to the air guide channels 5 in the mounting grooves 4. In this way, the air inside the factory building can be discharged outside the factory building along the air guide channel 3, the first chamber 2, the air guide channels 5, the air ports 8, and the exhaust channel 9. The gas flow provides a delivery channel; since the fan blades 7 on the column 6 are set at an incline, several fan blades 7 are set at an incline in the circumferential direction of the rotating cylinder 1. When the air flows through the location of several fan blades 7, the airflow blowing to the windward side of the outer wall of the fan blade 7 will be guided by the outer wall of the fan blade 7 and deviate from the rotating cylinder 1, while the airflow blowing to the leeward side of the inner wall of the fan blade 7 cannot be guided by the fan blade 7. That is, this part of the airflow can provide an effective driving force for the fan blade 7. Compared with the airflow blowing to the windward side of the fan blade 7, the driving force provided by the airflow blowing to the leeward side is more effective and direct. Thus, the airflow outside the factory building is used to make the rotating cylinder 1 and several fan blades 7 on it rotate. It should be noted that since several fan blades 7 are distributed around the circumference of the rotating cylinder 1, airflow in any direction other than vertical airflow, such as horizontal or inclined airflow, will provide rotational power for the rotating cylinder 1. During use, due to the temperature or pressure difference between the inside and outside of the factory, the air inside the factory can be discharged through the air guide channel 3, the first chamber 2, the air guide groove 5, the air outlet 8 and the exhaust channel 9. Since the fan blade 7 is set at an angle, the discharged air will provide the fan blade 7 with a driving force along the circumference of the rotating cylinder 1, thereby causing the rotating cylinder 1 to rotate. In addition, the air flow outside the factory will also provide power for the rotation of the rotating cylinder 1, thereby accelerating the discharge of air inside the factory, improving the ventilation and air exchange effect inside the factory, and thus improving the air conditioning effect. By employing several inclined fan blades 7, the rotating cylinder 1 and fan blades 7 can be easily rotated by utilizing the external airflow of the factory, which helps to extract the air from inside the factory, improve ventilation, and thus improve air conditioning efficiency. At the same time, this method can utilize the airflow in any horizontal or inclined direction to provide power, thereby improving the functionality of the device.

[0019] Furthermore, such as Figure 3 As shown, the horizontal and vertical cross-sectional shapes of the fan blade 7 are both arc-shaped, and the exhaust channel 9 is also arc-shaped. Since the airflow outside the factory can be horizontal or inclined, the shape of the fan blade 7 can be specially designed to smoothly receive the driving force provided by the airflow and improve the conversion efficiency of wind power into driving force. Specifically, the horizontal cross-section of the fan blade 7 is set to be arc-shaped, which can facilitate the guidance and reception of horizontal airflow. The vertical cross-section of the fan blade 7 is set to be arc-shaped, which can facilitate the guidance and reception of inclined airflow. This improves the effect of airflow driving the rotating cylinder 1 to rotate and improves the air guiding efficiency. The arc-shaped design of the exhaust channel 9 facilitates the improvement of air discharge efficiency during centrifugal rotation when the drum 1 is rotating.

[0020] Furthermore, such as Figure 3 As shown, the opening of the exhaust passage 9 is located on the inner wall of the end of the fan blade 7 away from the rotating cylinder 1; When air is exhausted from the factory, if the exhaust point is located on the windward side of the fan blade 7, the wind from outside the factory will blow directly to the exhaust point, obstructing the air exhaust and affecting the exhaust effect. If the exhaust point is located on the leeward side of the fan blade 7, the exhaust air will be located within the rotation area of ​​the fan blade 7, causing this part of the air to come into contact with the windward side of the fan blade 7, thus obstructing the rotation of the fan blade 7. Only by setting the exhaust point at the end of the fan blade 7 away from the rotating cylinder 1 and on the leeward side can the exhaust air quickly leave the operating area of ​​the fan blade 7, and the reverse thrust of the airflow further improve the rotation effect of the fan blade 7.

[0021] Furthermore, the column 6 is rotatably mounted within the mounting groove 4; Since the wind force outside the factory building will vary, if the opening angle of the fan blade 7 on the rotating cylinder 1 is large when the wind force is strong, the rotation speed of the rotating cylinder 1 will be too fast. Conversely, if the opening angle of the fan blade 7 is small when the wind force is weak, the rotation speed of the rotating cylinder 1 will be too slow. Therefore, the column 6 can be configured to rotate within the mounting slot 4 to facilitate the adjustment of the opening angle of the fan blade 7 on the rotating cylinder 1 according to the external wind force. When the column 6 rotates, its upper air port 8 and the air guide groove 5 remain at least partially connected.

[0022] Furthermore, such as Figure 4 and Figure 5 As shown, the rotating drum 1 has a second chamber 10. Several rotating columns 11 that are rotatably connected to each column 6 are rotatably arranged in the second chamber 10. Each rotating column 11 has a spiral groove 12 on its outer wall. A sliding column 13 is slidably arranged in the spiral groove 12. An adjusting plate 14 coaxial with the rotating drum 1 is provided in the second chamber 10. The adjusting plate 14 moves along the axis of the rotating drum 1. In this invention, the second chamber 10 is formed by the outer wall of the air guide channel 3 and the inner wall of the rotating cylinder 1, and a disc is added inside the rotating cylinder 1, so that the outer wall of the air guide channel 3, the inner wall of the rotating cylinder 1, and the disc together form the second chamber 10. The second chamber 10 is annular, mainly providing installation space for the rotating column 11, the spiral groove 12, the sliding column 13, and the adjusting disc 14. The end of each rotating column 11 passes through the rotating cylinder 1 and is coaxially connected to the corresponding column body 6. Thus, when the rotating column 11 rotates, it will drive the column body 6 and the fan blade 7 to rotate. The opening angle of the fan blades 7 is adjusted. Since the adjusting disk 14 is connected to several spiral grooves 12 through several sliding columns 13 and the sliding columns 13 are slidably installed in the spiral grooves 12, the movement of the adjusting disk 14 in the circumferential direction is restricted, and it can only move in the vertical direction. When the adjusting disk 14 moves vertically, it will push the sliding columns 13 to slide in the spiral grooves 12, thereby pushing the rotating column 11 to rotate. At the same time, since the adjusting disk 14 can drive several rotating columns 11 to rotate synchronously, the opening angle of several fan blades 7 can be adjusted at the same time.

[0023] Furthermore, such as Figure 5 As shown, the inner wall of the second chamber 10 is provided with threads, and a threaded ring 15 is screwed onto the threads. The adjusting disc 14 is rotatably sleeved on the threaded ring 15. An adjustment motor 16 is installed in the second chamber 10. A transmission shaft 17 is installed at the output end of the adjustment motor 16. A transmission wheel 18 is installed on the transmission shaft 17. The transmission wheel 18 is rotatably connected to the adjustment disc 14. Among them, the drive shaft 17 is a telescopic structure; The regulating motor 16 mainly provides power for the rotation of the threaded ring 15, which in turn provides support for the regulating disc 14. When the regulating motor 16 is running, it drives the threaded ring 15 to rotate via the drive shaft 17 and the drive wheel 18. Since the threaded ring 15 engages with the thread in the second chamber 10, it moves vertically, which in turn drives the regulating disc 14 to move vertically, thus providing power for the movement of the regulating disc 14. Since the drive wheel 18 is rotatably mounted on the regulating disc 14, the drive shaft 17 also provides support and limits for the regulating disc 14. When the regulating disc 14 moves vertically, it drives the drive wheel 18 to move synchronously, and the drive shaft 17 performs telescopic movements, thereby ensuring that the drive wheel 18 and the threaded ring 15 are always in a transmission state.

[0024] Furthermore, such as Figure 4 and Figure 6 As shown, a base 19 is provided at the bottom of the rotating drum 1. The rotating drum 1 is rotatably mounted on the base 19, and the bottom of the rotating drum 1 and the base 19 form a third chamber 20. A drive motor 21 is provided in the third chamber 20. A drive wheel 22 is provided at the output end of the drive motor 21. The drive wheel 22 is connected to the rotating drum 1 in a transmission manner. The third chamber 20 is equipped with several battery packs 23 that are electrically connected to the drive motor 21. The base 19 is equipped with an air guide hopper 25 that is connected to the air guide channel 3. The air guide hopper 25 is used to transport the air in the factory to the first chamber 2. When the rotating drum 1 rotates, it can drive the drive motor 21 through the drive wheel 22 to generate electrical energy. Several battery packs 23 can be used to store electrical energy. When the wind outside the factory is weak, in order to ensure the normal ventilation efficiency of the rotating drum 1, the battery packs 23 can be used to drive the drive motor 21 in reverse to provide auxiliary power for the rotation of the rotating drum 1. In this way, electrical energy can be generated and stored when the wind is strong, and when the wind is weak, it can provide electrical energy to the drive motor 21 in reverse and drive the rotating drum 1 to rotate. The base 19 can provide support for the rotating drum 1. The base 19 is installed on the top of the factory building. The air guide hopper 25 is used to connect the air guide channel 3 and the interior of the factory building. In some embodiments, in order to avoid the high temperature generated by the drive motor 21 and the battery pack 23, several heat dissipation holes or other structures can be opened on the base 19.

[0025] Furthermore, a controller 24 for adjusting the current between the drive motor 21 and the battery pack 23 is provided in the third chamber 20; The controller 24 can be used to adjust and limit the current input to the drive motor 21 or the current output when the drive motor 21 generates electricity, so as to adjust the rotation speed of the drum 1 according to the external wind force.

[0026] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
