[0001] This utility model relates to an optimization device for uniform air supply temperature, and more particularly to its air mixing and stirring structure, belonging to the technical field of air supply equipment. Background Technology

[0002] In industrial production, hot or cold air equipment is frequently used. In some experiments or production projects, uneven temperature can cause test results to deviate from the true values, reducing accuracy and reliability. The patent applicant analyzed the causes of temperature unevenness, concluding that since hot or cold air is colorless, it is impossible to visually determine whether the temperature of the supplied air is uniform. Existing air supply equipment lacks a stirring device, leading to insufficient mixing of hot and cold air. Therefore, how to stir the air to improve the uniformity of the supplied air temperature is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an optimized device for uniform air supply temperature.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an optimization device for uniform air supply temperature, comprising a fan, a heater, and a first air duct, wherein the air outlet of the fan is connected to the inlet of the heater, and the outlet of the heater is connected to the inlet of the first air duct.

[0005] The optimized air supply temperature uniformity device also includes a housing, a sealing plate, a motor, bolts, threaded holes, a second air duct, a rotating shaft, a coupling, and a turbine. The housing is cup-shaped, with several threaded holes on its edge. The edge of the sealing plate is screwed to the threaded holes by several bolts. The center of the housing is connected to the outlet of the first air duct. The middle part of the rotating shaft is rotatably connected to the center of the sealing plate. One end is connected to the motor through a coupling, and the other end is connected to the turbine. Several spiral grooves are provided on the side of the turbine.

[0006] The present invention is further configured such that: a front guide wheel is connected to the turbine, the front guide wheel extends into the center of the first air duct, and several propellers are provided on the side.

[0007] A further feature of this invention is that a plurality of stirring paddles are connected radially to the rotating shaft.

[0008] The present invention is further configured such that a return pipe is connected between the first air duct and the second air duct, and a valve is provided on the return pipe.

[0009] A further feature of this invention is that one end of the return pipe is inserted into the center of the first air duct.

[0010] A further feature of this invention is that a sealing mechanism is provided between the cover plate and the rotating shaft.

[0011] The present invention is further configured such that: a plurality of spiral rifling grooves are provided on the inner wall of the first air duct.

[0012] The present invention is further configured such that the side shape of the turbine is the same as the bottom inner wall shape of the housing, and the turbine is a truncated cone shape.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: A turbine is installed within the outer casing and the sealing plate, with several spiral grooves on its side; the second air duct is connected to the tangent of the outer casing. The motor drives the shaft and turbine to rotate via a coupling. The air from the first air duct is evenly divided into several portions by the spiral grooves and accelerated, then re-converges between the turbine and the sealing plate.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] Referring to Figures 1-5, an optimized device for uniform air supply temperature in this embodiment includes a fan 1, a heater 2, a first air duct 3, a housing 4, a sealing plate 8, a motor 7, bolts 5, threaded holes 12, a second air duct 9, a rotating shaft 16, a coupling 17, and a turbine 13. The air outlet of the fan 1 is connected to the inlet of the heater 2, and the outlet of the heater 2 is connected to the inlet of the first air duct 3. The housing 4 is cup-shaped, with several threaded holes 12 on its edge. The edge of the sealing plate 8 is screwed to the threaded holes 12 by several bolts 5. The center of the housing 4 is connected to the outlet of the first air duct 3. The middle part of the rotating shaft 16 is rotatably connected to the center of the sealing plate 8. One end is connected to the motor 7 through the coupling 17, and the other end is connected to the turbine 13. Several spiral grooves 18 are provided on the side of the turbine 13. The second air duct 9 is connected to the tangent of the housing 4.

[0022] Because a turbine 13 is installed within the outer casing 4 and the sealing plate 8, and the turbine 13 has several spiral grooves 18 on its side; the second air duct 9 is connected to the tangent of the outer casing 4. The motor 7 drives the rotating shaft 16 and the turbine 13 to rotate via the coupling 17. The air from the first air duct 3 is evenly divided into several parts by the spiral grooves 18 and rotates at an accelerated speed, then re-merges between the turbine 13 and the sealing plate 8. The turbine 13 thoroughly and evenly mixes air of different temperatures, resulting in a more uniform temperature of the air discharged through the second air duct 9. The test results of the production project are closer to the actual values, improving accuracy and reliability.

[0023] To guide the air in the first duct 3 through the spiral groove 18, this invention is further configured such that: a front guide wheel 14 is connected to the turbine 13, the front guide wheel extends into the center of the first duct 3, and several propellers 19 are arranged on its side. The front guide wheel 14 is truncated conical in shape. The front guide wheel 14 and the propellers 19 rotate with the turbine 13, driving the air in the first duct 3 to accelerate towards the duct wall until it enters the spiral groove 18.

[0024] To improve the uniformity of air temperature and mix the air between the turbine 13 and the sealing plate 8, this invention further includes a plurality of stirring paddles 15 connected radially to the rotating shaft 16. The propellers 19 rotate with the rotating shaft 16, further stirring and mixing the air between the turbine 13 and the sealing plate 8, resulting in a more uniform air temperature.

[0025] If the air discharged from the second duct 9 is sufficiently uniform, it can be used. If the air discharged from the second duct 9 is not uniform enough, it is unsatisfactory. To further mix the air and improve its temperature uniformity, a return pipe 10 is connected between the first duct 3 and the second duct 9, and a valve 11 is installed on the return pipe 10. By controlling the opening of the valve 11, the airflow entering the first duct 3 through the return pipe 10 is controlled. The greater the airflow, the more uniform the mixing.

[0026] To create turbulence in the first duct 3, this invention further includes the following configuration: one end of the return pipe 10 is inserted into the center of the first duct 3. The return pipe 10 disturbs the airflow in the first duct 3, promoting turbulence. The more intense the turbulence, the better the air mixing effect in the first duct 3.

[0027] To prevent air leakage between the rotating shaft 16 and the cover plate, the present invention is further provided with a sealing mechanism 6 between the cover plate and the rotating shaft 16.

[0028] To further promote air mixing, this invention is further configured such that the inner wall of the first air duct 3 is provided with a plurality of spiral rifling grooves 20. The air rotates within the spiral rifling grooves 20, moving in a different direction than the air outside the rifling grooves 20. The air inside and outside the rifling grooves 20 collides and rubs against each other, resulting in more uniform mixing. The air in the rifling grooves 20 enters the spiral grooves 18 at a faster speed and merges more quickly between the sealing plate 8 and the turbine 13. This further enhances the uniformity of the mixing.

[0029] To increase wind speed and enhance mixing, the air is directed to pass primarily through the spiral groove 18, rather than between the turbine 13 and the bottom inner wall of the outer casing 4. The side profile of the turbine 13 is identical to that of the bottom inner wall of the outer casing 4, and the shortest distance from any point on the side of the turbine 13 to the inner wall of the outer casing 4 is equal. The turbine 13 is truncated conical in shape. Preferably, the shortest distance from any point on the side of the turbine 13 to the inner wall of the outer casing 4 is less than 5 mm. The smaller the distance, the less air passes between the turbine 13 and the bottom of the outer casing 4, resulting in more uniform mixing.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
