Detailed Description
The invention will be described in further detail with reference to the accompanying drawings:
fig. 1 shows a top view of the device structure, and the high-temperature constant-air-volume automatic complementary distribution device comprises a distribution chamber (1), an air inlet (2), a first air outlet (3), a second air outlet (4), a main shaft (5), a rotary sealing structure (6), a distributor (7) and a heat insulation layer (8).
In fig. 1, the distribution chamber (1) is a flat cylinder hollow structure, the air inlet (2), the first air outlet (3) and the second air outlet (4) are circular holes, and the distribution chamber is identical in structure and size and is respectively connected with an external pipeline. The air inlet (2) is positioned on the side wall of the left side of the distribution chamber (1), and the first air outlet (3) and the second air outlet (4) are positioned on the side wall of the right side of the distribution chamber (1). Hot air enters the distribution chamber (1) from the air inlet (2) and then is discharged through the first air outlet (3) and the second air outlet (4), and because the central distances between the air inlet (2) and the first air outlet (3) and the second air outlet (4) are equal, the air pressure passing through the first air outlet (3) and the second air outlet (4) is uniform.
In fig. 1 and 2, a main shaft (5) passes through a distribution chamber (1) and is fixed by a rotary sealing structure (6) arranged on the upper surface and the lower surface of the distribution chamber (1), and a distributor (7) is positioned in the distribution chamber (1) and is of a fan-shaped cylindrical structure and fixed on the main shaft (5) to rotate along with the main shaft. The first air outlet (3), the second air outlet (4) and the distributor (7) form a rotating fit relation, and when the distributor (7) rotates to a proper angle, the first air outlet (3) or the second air outlet (4) can be completely shielded, but the air inlet (2) cannot be shielded.
In fig. 1, the distributor (7) is rotated to completely shield the first air outlet (3), and at this time, the hot air entering from the air inlet (2) flows through the distribution chamber (1), bypasses the distributor (7), and is directly discharged through the second air outlet (4), and because the air inlet (2) and the second air outlet (4) have the same structure and size, the air pressure, the air speed and the like are basically not influenced. Obviously, the same effect is obtained if the distributor (7) is rotated in a position such as to completely shield the second outlet mouth (4).
In fig. 1, the circumferential arc length of the distributor (7) is equal to the sum of the arc length of the side wall of the distribution chamber (1) occupied by the first air outlet (3) and the arc length of the side wall of the distribution chamber (1) between the first air outlet (3) and the second air outlet (4). When the distributor (7) rotates clockwise, because the first air outlet (3) and the second air outlet (4) are the same in structure and size, the first air outlet (3) exposes a large ventilation section, and the second air outlet (4) can be shielded by the large ventilation section, namely, the sum of the exposed ventilation sections of the first air outlet (3) and the second air outlet (4) is always constant and is equal to the ventilation section of the air inlet (2), so that the constant air volume complementary distribution relation of the air outlets is automatically realized, and the influence on the air pressure, the flow rate and the like of hot air is small. Obviously, the design has the advantages of simple structure and control, lower cost, reliable operation, convenient maintenance and the like.
In fig. 2, the distribution chamber (1) is enclosed by a heat insulating layer (8), and the heat insulating layer (8) is arranged between the rotary sealing structure (6) and the upper surface and the lower surface of the distribution chamber (1). When high-temperature hot air flows through the distribution chamber (1), the possible heat transfer path can only be transferred to the main shaft (5) through the distributor (7) and then transferred to the rotary sealing structure (6) through the main shaft, but the high-temperature hot air is difficult to be directly transferred to the rotary sealing structure (6) through the upper wall surface and the lower wall surface of the distribution chamber (1), so that the rotary sealing structure (6) is protected to a certain extent.
In fig. 2, the distributor (7) can be further made of heat insulating materials, even if the main shaft (5) is made of heat conducting metal materials, heat insulating materials are arranged between the high-temperature hot air and the main shaft (5) and between the high-temperature hot air and the rotary sealing structure (6), and heat is difficult to directly transfer to the rotary sealing structure (6), so that the protection effect is better. Of course, the main shaft (5) can be made of heat-insulating material or a combination of metal material and heat-insulating material, so that the whole heat-insulating effect is optimal.
The rotary sealing structure (6) generally needs to contain bearings, lubricating oil and the like, the high-temperature working environment has great influence on the lubrication, the service life and the like of the rotary sealing structure, the design of the rotary sealing structure can obviously effectively reduce the temperature of the working environment, and the operation reliability and the service life of the rotary sealing structure (6) are ensured; meanwhile, the heat loss is effectively reduced, and the efficiency of the device is improved.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
