Description

Technical Field

[0001] The utility model relates to the technical field of air cold and hot separators, in particular to an air cold and hot separator. Background Art

[0002] An air heat separator is a special device that is mainly used to separate the hot and cold components in the air. This type of equipment has a wide range of applications, ranging from industrial processes to aerospace. Its working principle and design vary according to the specific application scenario. The turbine blades inside the current air heat separator generally adopt an integrated curved design or an integrated inclined design. Although this design can also form a swirl effect, the swirl effect is not good and cannot achieve a good airflow separation effect. Moreover, the current air heat separator has a fixed air outlet size and cannot be adjusted in a targeted manner. In view of this, we propose an air heat separator. Utility Model Content

[0003] In order to make up for the above deficiencies, the utility model provides an air cold and hot separator.

[0008] The hot air outlet portion is aligned with the hot and cold air flow separation portion and is used to separate the hot air flow. A hot air outlet regulating baffle is arranged on the hot air outlet portion. The hot air outlet regulating baffle is rotated to adjust the air outlet size.

[0009] As a preferred embodiment of the present invention, the casing is a hollow straight-through tube body with unsealed front and rear ends.

[0010] As a preferred embodiment of the present invention, the motor fixing frame is fixed to the front end outlet of the casing through a plurality of connecting rods thereon, and a first central air outlet is provided at the central position of the motor fixing frame.

[0011] As a preference of the present utility model, the cold and hot air separation part is composed of a turbine fan blade fixing pipe and a number of turbine fan blades. The turbine fan blade fixing pipe is rotatably arranged inside the casing, and a number of turbine fan blades are fixed on the periphery of the turbine fan blade fixing pipe and are arranged at uniform equal intervals.

[0012] As a preference of the present utility model, a second central air outlet hole is arranged at the center of the rotor of the hollow brushless motor, and the front end of the turbine fan blade fixing pipe is fixed on the rotor of the hollow brushless motor.

[0013] As a preference of the present utility model, the cold air outlet pipe, the second central air outlet hole and the turbine fan blade fixing pipe are located on the same straight line. After the cold air enters the turbine fan blade fixing pipe, it escapes outwards from the second central air outlet hole and the cold air outlet pipe.

[0014] As a preference of the present utility model, the hot air outlet part is composed of a hot air outlet plate and a hot air outlet adjusting baffle. The hot air outlet plate is fixed at the rear end outlet of the casing, and the hot air outlet adjusting baffle is rotatably arranged on the surface of the hot air outlet plate. Rotating the hot air outlet adjusting baffle is used to adjust the air outlet size of the hot air outlet plate.

[0015] As a preference of the present utility model, the rear end of the turbine fan blade fixing pipe is rotatably installed at the center of the hot air outlet plate, and the two are connected by a bearing. The inner ring of the bearing is fixed to the turbine fan blade fixing pipe, and the outer ring of the bearing is fixed to the hot air outlet plate.

[0016] As a preference of the present utility model, a number of cold air separation holes are arranged on the surface of the turbine fan blade fixing pipe, and the diameters of the cold air separation holes increase sequentially from front to back.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] The utility model starts the hollow brushless motor to drive the turbine blade fixing tube and the turbine blades thereon to rotate. During the rotation of the turbine blades, the external air flow is sucked in and enters the space between the turbine blades. Due to the arc-shaped arrangement of the turbine blades, the air flow is continuously thrown backwards in a vortex shape. Since the hot air is light, it will expand toward the outer circle, and the cold air is heavy. The turbine rotates to capture the cold air with heavier weight, so that the cold air gathers at the turbine blade fixing tube. Through the principle of specific gravity between hot and cold air, the cold air is merged into the turbine blade fixing tube through the cold air separation holes between the turbine blades. Moreover, since the rear end of the turbine blade fixing tube is closed, the cold air gathered in the turbine blade fixing tube will be continuously squeezed by the cold air flow that is continuously delivered, and a recoil effect is formed. The squeezed and recoiled cold air The airflow will escape in the opposite direction, that is, escape to the front end of the turbine blade fixing tube, and escape outward through the second central air outlet and the cold air outlet pipe, while the hot air will be gathered in the outer circle and continuously pushed backwards, and will eventually escape from the first hot air outlet on the hot air outlet plate and the second hot air outlet on the hot air outlet adjusting baffle. In this process, the overlapping area between the second hot air outlet and the first hot air outlet can be changed by rotating the hot air outlet adjusting baffle, so that the size of the air outlet can be adjusted, and the bending curvature of the front blade body is preferably 30 degrees, and the bending curvature of the rear blade body is 46 degrees. This curvature setting can improve the guidance of the airflow, promote the airflow to enter the interior of the casing more smoothly, and make it easier for the incoming airflow to form a vortex, which can increase the separation effect of the hot and cold airflows.

[0030] Please refer to Figures 1-6 , the above technical solutions of the present invention are described in detail through the following embodiments:

[0031] An air cold and hot separator includes a housing 1 wrapped around the periphery, and further includes:

[0032] A motor fixing bracket 2, the front end of the motor fixing bracket 2 is fixedly installed with a cold air outlet pipe 4, and the rear end of the motor fixing bracket 2 is fixedly installed with a hollow brushless motor 5;

[0033] A cold and hot air flow separation part, on which a number of turbine fan blades 7 bent in two sections are installed. The cold and hot air flow separation part is installed on the hollow brushless motor 5, and the hollow brushless motor 5 drives the cold and hot air flow separation part to rotate, centrifugally separating the cold and hot air flows, and the cold air flows out from the cold air outlet pipe 4;

[0034] A hot air outlet part, which is aligned with the cold and hot air flow separation part for separating the hot air flow. A hot air outlet adjustment baffle 8 is provided on the hot air outlet part, and by rotating the hot air outlet adjustment baffle 8, the air outlet size can be adjusted.

[0035] Preferably, the casing 1 is a hollow straight tube body with open ends at the front and rear.

[0036] Preferably, the motor fixing bracket 2 is fixed to the front end outlet of the casing 1 through a plurality of connecting rods, and a first central air outlet hole 20 is provided at the center position of the motor fixing bracket 2. An air intake area is formed between two adjacent connecting rods on the motor fixing bracket 2. External air will continuously enter the interior of the casing 1 from the air intake area under the suction force of the rotation of the turbine fan blades 7.

[0037] Preferably, the cold and hot air separation part is composed of a turbine fan blade fixing tube 6 and a plurality of turbine fan blades 7. The turbine fan blade fixing tube 6 is rotatably arranged inside the casing 1, and a plurality of turbine fan blades 7 are fixed on the periphery of the turbine fan blade fixing tube 6 and are arranged at equal intervals. A plurality of cold air separation holes 60 are provided on the surface of the turbine fan blade fixing tube 6. The diameter of the cold air separation holes 60 increases sequentially from front to back, and the rear end of the turbine fan blade fixing tube 6 is closed.

[0038] Moreover, the cold air separation holes 60 are distributed between two adjacent turbine fan blades 7, as Figure 5 shown.

[0039] It should be added that each turbine fan blade 7 is composed of a front blade body 71 and a rear blade body 72. Both the front blade body 71 and the rear blade body 72 are arc-shaped blade bodies. The bending radian of the front blade body 71 is 25 - 40 degrees, and the bending radian of the rear blade body 72 is 40 - 50 degrees.

[0040] Furthermore, in this embodiment, the bending radian of the front blade body 71 is preferably 30 degrees, and the bending radian of the rear blade body 72 is 46 degrees. This radian setting can improve the guidance of the air flow, promote the air flow to enter the interior of the casing 1 more smoothly, and make it easier for the incoming air flow to form a vortex shape, which can increase the separation effect of the cold and hot air flows. During the rotation of the turbine fan blades 7, the external air flow is sucked in and enters the space between the turbine fan blades 7. Due to the arc-shaped setting of the turbine fan blades 7, the air flow will be continuously thrown backward in a vortex shape. Since hot air is light and will expand outward, and cold air is heavy, the turbine rotation captures the heavier cold air, causing the cold air to gather towards the inner circle. Through the principle of the specific gravity between hot and cold air, the cold air enters the turbine fan blade fixing tube 6 through the cold air separation holes 60 between the turbine fan blades 7. And because the rear end of the turbine fan blade fixing tube 6 is closed, the cold air gathered in the turbine fan blade fixing tube 6 will be continuously squeezed by the continuously incoming cold air flow and form a counter-pulse effect. The cold air flow squeezed and counter-pulsed will escape in the opposite direction, that is, escape from the front end of the turbine fan blade fixing tube 6 and pass through the second central air outlet hole 50 and the cold air outlet pipe 4 to escape outward.

[0041] As a preferred embodiment of the present invention, a second central air outlet 50 is provided at the center of the rotor of the hollow brushless motor 5 , and a front end of the turbine blade fixing tube 6 is fixed on the rotor of the hollow brushless motor 5 .

[0042] As a preferred embodiment of the present invention, the cold air outlet pipe 4, the second central air outlet hole 50 and the turbine blade fixing pipe 6 are located on the same straight line. After the cold air flow enters the turbine blade fixing pipe 6, it escapes outward from the second central air outlet hole 50 and the cold air outlet pipe 4.

[0043] As a preferred embodiment of the utility model, the hot air outlet part is composed of a hot air outlet plate 3 and a hot air outlet adjustment baffle 8. The hot air outlet plate 3 is fixed at the rear end outlet of the casing 1, and the hot air outlet adjustment baffle 8 is rotatably arranged on the surface of the hot air outlet plate 3. Rotating the hot air outlet adjustment baffle 8 is used to adjust the air outlet size of the hot air outlet plate 3.

[0044] It should be supplemented that an outer convex edge 30 is fixed at the outer edge of the hot air outlet plate 3, a first central circular hole 31 is provided at the center of the outer convex edge 30, an inner convex edge 33 is installed at the opening of the first central circular hole 31, a lever through hole 32 is provided on the outer convex edge 30, and a plurality of evenly arranged first hot air outlet holes 34 are provided in the area between the outer convex edge 30 and the inner convex edge 33.

[0045] It should be added that a lever is fixed on the hot air outlet regulating baffle 8, and the lever passes through the lever through-hole 32 and extends to the outside. The lever can be moved by hand to drive the hot air outlet regulating baffle 8 to rotate. A second center circular hole 82 is provided at the center of the hot air outlet regulating baffle 8, and the second center circular hole 82 is sleeved on the outer periphery of the inner convex edge 33. The hot air outlet regulating baffle 8 is provided with a plurality of evenly distributed second hot air outlet holes 81.

[0046] Furthermore, the spacing between two adjacent first heat outlet holes 34 and the spacing between two adjacent second heat outlet holes 81 are equal, and the two have the same size. By rotating the heat outlet adjustment baffle 8, the first heat outlet holes 34 and the second heat outlet holes 81 can be made to face each other or staggered with each other.

[0047] As a preferred embodiment of the utility model, the rear end of the turbine blade fixing tube 6 can be rotatably installed at the center of the hot air outlet plate 3, and the two are connected by a bearing 9, the inner ring of the bearing 9 is fixed to the turbine blade fixing tube 6, and the outer ring of the bearing 9 is fixed to the hot air outlet plate 3.

[0048] During specific use, start the hollow brushless motor 5 to drive the turbine fan blade fixing pipe 6 and the turbine fan blades 7 thereon to rotate. During the rotation of the turbine fan blades 7, external air flow is inhaled and enters the space between the turbine fan blades 7. Since the turbine fan blades 7 are arc-shaped, the air flow will be continuously thrown backward in a vortex shape. Because hot air is lighter and will expand outward in a circle, and cold air is heavier, the turbine rotation captures the colder air with a higher weight, causing the cold air to gather towards the turbine fan blade fixing pipe 6. Through the principle of specific gravity between hot and cold air, the cold air enters the turbine fan blade fixing pipe 6 through the cold air separation holes 60 between the turbine fan blades 7. And because the rear end of the turbine fan blade fixing pipe 6 is closed, the cold air gathered in the turbine fan blade fixing pipe 6 will be continuously squeezed by the continuously incoming cold air flow, and a recoil effect is formed. The squeezed and recoiled cold air flow will escape in the opposite direction, that is, escape from the front end of the turbine fan blade fixing pipe 6, and pass through the second central air outlet hole 50 and the cold air outlet pipe 4 to escape outward. The hot air will be gathered in the outer circle and continuously pushed backward, and finally escape from the first hot air outlet hole 34 on the hot air outlet plate 3 and the second hot air outlet hole 81 on the hot air outlet adjusting baffle 8. During this process, by rotating the hot air outlet adjusting baffle 8, the overlapping area between the second hot air outlet hole 81 and the first hot air outlet hole 34 can be changed, so as to adjust the size of the air outlet. Through the above process, the separation of hot and cold air is achieved.

[0049] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
