Description

TECHNICAL FIELD

[0001] The present application relates to the field of hot air machines, in particular to an ultrahigh-temperature thermal energy wind wheel. BACKGROUND

[0002] The hot air machine is the first choice for upgrading of modern industrial heat sources, and the mechanical and electrical equipment is the best hot air source configuration for automatic machines such as hot air conveying furnaces, drying furnaces, ovens, and packaging machines. The hot air machine is composed of a blower, a heater, and a control circuit. It realizes the regulation and control of working temperature and air volume.

[0003] Chinese patent CN115750402B discloses a hot air machine with air flow collision, which includes a fan circular shell and a rotating heat generating assembly. The rotating heat generating assembly is arranged in the fan circular shell and connected with the main shaft end of a driving motor. The rotating heat generating assembly includes a first end cover and a second end cover. The first end cover is connected with the main shaft end of the driving motor, and the second end cover is arranged in parallel on one side of the first end cover. First and second circular arc flow guide vanes are arranged between the first and second end covers.

[0004] The existing technical solution has the following disadvantages: the air flow introduced by the existing technical solution enters from the edge of the wind wheel. The blades of the wind wheel are distributed in a circle. When the wind wheel rotates, the edge area of the end cover directly opposite the blades is directly stirred by the blades, forming a strong negative pressure area. The air is quickly rolled into the air duct, the flow rate is high, the air flow in the high flow rate area cuts in quickly, and the impact shear with the air duct wall and the wind wheel blade is strong, and the heat generation is sufficient. The negative pressure intensity is greatly weakened in the area directly opposite the blade gap, forming a weak negative pressure area. The air rolling speed is slow, the flow rate is low, the air flow in the low flow rate area cuts in slowly, the turbulence intensity is weak, and the heat generation is insufficient. Ultimately, the local temperature rise in the air duct is different, and the overall hot air temperature rise efficiency is lower than that when the air flows uniformly. SUMMARY

[0005] The present application provides an ultrahigh-temperature thermal energy wind wheel, which can solve the problem that the air flow introduced by the existing scheme enters from the edge of the wind wheel.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, an embodiment of the present invention provides an ultra-high temperature thermal energy wind turbine, including a housing 100, a front cover 200 disposed on the housing 100, a wind turbine body 300, and an installation assembly 400; An installation roller 500 is provided between the front cover 200 and the housing 100. The installation roller 500 is rotatably connected to the housing 100 through a bearing. The impeller body 300 is mounted on the installation roller 500 through the installation assembly 400. The front plate cover 200 and the shell 100 are provided with an exhaust fan 600, the mounting roller 500 is provided with a fixing assembly 700, the exhaust fan 600 is installed on the mounting roller 500 through the fixing assembly 700, the rotating direction of the exhaust fan 600 is consistent with the rotating direction of the wind wheel body 300, and the angle of the blade of the exhaust fan 600 is designed to guide the airflow to enter the air duct along the rotating direction of the wind wheel body 300, that is, the airflow direction of the exhaust fan 600 is consistent with the rotating direction of the wind wheel body 300.

[0023] The working principle of the above-mentioned super-high-temperature heat energy wind wheel is as follows: air enters the shell 100 from the air inlet pipe 201 through the existing air inlet device outside, since the air inlet 306 of the wind wheel body 300 is arranged at the side edge, the air enters the air duct of the wind wheel body 300 from the edge of the wind wheel body 300, the servo motor 102 drives the mounting roller 500 to rotate, the mounting assembly 400 and the fixing assembly 700 are arranged to drive the wind wheel body 300 and the exhaust fan 600 to rotate synchronously, the angle of the blade of the exhaust fan 600 is designed to guide the airflow to enter the air duct along the rotating direction of the wind wheel body 300, that is, the airflow direction of the exhaust fan 600 is consistent with the rotating direction of the wind wheel body 300, so that the airflow enters the air duct of the wind wheel in equal amount and in the same direction, the airflow forms a spiral rotating flow in the air duct, and is continuously rubbed and compressed, so that the air is heated, and finally the heated air is discharged from the air outlet pipe 103 through the centrifugal thrust generated by the rotation of the wind wheel body 300 and the pressure difference between the side of the air inlet 306 and the side of the air outlet.

[0024] The existing technical scheme is that the airflow enters from the edge of the wind wheel, the blades of the wind wheel are distributed in a circle, when the wind wheel rotates, the edge region of the end cover directly opposite the blades is directly stirred by the blades, a strong negative pressure area is formed, the air is quickly rolled into the air duct, the flow rate is high, and the heat generation is sufficient; the region directly opposite the gap between the blades is not directly affected by the blades, the negative pressure strength is greatly weakened, a weak negative pressure area is formed, the air rolling speed is slow, and the heat generation is insufficient. The local temperature rise in the air duct is different, and the overall hot air temperature rise efficiency is lower than that when the air enters uniformly. In contrast, the application installs an exhaust fan 600 coaxial with, rotating in the same direction as and at the same speed as the wind wheel body 300 between the wind wheel body 300 and the air inlet pipe 201, and each blade of the exhaust fan 600 will continuously suck the corresponding region of the annular air inlet 306 when the exhaust fan 600 rotates synchronously, a uniform annular negative pressure field is formed at the air inlet 306, the external air is forced to enter the V-shaped air duct 305 in equal amount and in the same direction along the edge of the front plate 302, the air flow rates on the two sides of the arc-shaped plate 304 are prevented from being different, the temperature rise in the air ducts on the two sides of the arc-shaped plate 304 is prevented from being different, and the overall hot air temperature rise efficiency is prevented from being lower than that when the air enters uniformly.

[0025] Referring to Figures 1 to 5As shown, the principle of the temperature rise of the wind wheel body 300 is described, the front plate cover 200 is fixedly installed on the shell 100 by screws, the front plate cover 200 is fixedly installed with the air inlet pipe 201, the bearing bracket 202 is installed in the air inlet pipe 201, one end of the installation roller 500 is rotatably arranged on the bearing bracket 202; the mounting bracket 101 is fixedly installed on the shell 100, the servo motor 102 is fixedly installed on the mounting bracket 101, the output end of the servo motor 102 is fixedly connected with one end of the installation roller 500, the air outlet pipe 103 is fixedly installed on the shell 100; the wind wheel body 300 comprises a front plate 302, a rear plate 303 and a plurality of arc-shaped plates 304, the plurality of arc-shaped plates 304 are fixedly installed in a circumferential array form between the front plate 302 and the rear plate 303, the tail ends of the two adjacent arc-shaped plates 304 are connected to form a V-shaped air duct 305, the top end of the arc-shaped plate 304 extends to the outer periphery of the rear plate 303, the diameter of the front plate 302 is less than that of the rear plate 303, so that the air enters the V-shaped air duct 305 from the air inlet 306 formed between the front plate 302 and the two arc-shaped plates 304; The front plate cover 200 is installed on the shell 100 by screws, air is introduced into the shell 100 through the air inlet pipe 201 by the existing air inlet device outside, and the servo motor 102 operates to drive the installation roller 500 to rotate, and the installation assembly 400 is arranged to drive the wind wheel body 300 to rotate. After the airflow enters the air inlet 306, it first enters the contraction section with a smaller cross section of the V-shaped air duct 305, and the flow rate is forced to increase sharply; then enters the expansion section with a larger cross section, and the flow rate decreases sharply. This sudden change from acceleration to deceleration will directly cause the airflow boundary layer to separate and generate a large amount of disordered turbulent vortex. At the same time, the arc-shaped wall surface of the arc-shaped plate 304 will force the airflow to change the flow direction, and the airflow will repeatedly rebound and shear between the two arc-shaped wall surfaces to form a combined motion of rotational flow and reciprocating impact. The shear force between the airflow layers is greatly increased, and the intensity and frequency of frictional heat generation increase exponentially. The front and rear front plates 302 and 303 also form a local backflow area in the air duct, and the backflow airflow collides with the main airflow, further increasing the degree of turbulence. At the same time, the annular air inlet allows the airflow to cut into the V-shaped air duct 305 from all around, forming an angle with the rotation direction of the wind wheel body 300. The relative speed of the airflow and the arc-shaped plate 304 is greatly increased, the stirring and shearing effect of the arc-shaped plate 304 on the airflow is stronger, and the wall surface of the V-shaped air duct 305 limits the radial diffusion of the airflow, forcing the airflow to make rotational motion in the V-shaped air duct 305, prolonging the contact time between the airflow and the wall surface of the arc-shaped plate 304, and the cumulative effect of frictional heat generation is more obvious. The V-shaped air duct 305 is more prone to generate strong turbulence, and the essence is that its structural characteristics are highly consistent with the target of frictional heat generation. By means of sudden change of cross section from contraction to expansion, forced guidance of arc-shaped wall surface and multi-dimensional impact of annular air inlet, flow field disorder and turbulent vortex are actively generated to improve the efficiency of frictional heat generation. The wind wheel body 300 can realize a wind volume adjustment output of 1200-1900 m3 / h under the condition of a rated input power of 45 kW, and the hot air temperature adjustment range of the air outlet is 240-650℃.

[0026] As shown in Figure 5 In order to prolong the airflow working time and further improve the efficiency of frictional heat generation, the arc-shaped spoiler 307 is fixedly installed in the V-shaped air duct 305. The tail end of the arc-shaped spoiler 307 does not contact the arc-shaped plate 304, and the top end of the arc-shaped spoiler 307 extends to the outer periphery of the rear plate 303. Air enters the V-shaped air duct 305 from the wide gap between the arc-shaped plate 304 and the arc-shaped spoiler 307. An arc-shaped spoiler 307 is arranged. Without the spoiler, part of the airflow will pass along the shortest path of the air duct in a straight line, not fully participating in the cyclone movement, and the friction heat generation is insufficient. The curvature of the arc-shaped spoiler 307 is matched in the same direction as the curvature of the air duct, which forces the airflow to flow along an arc-shaped trajectory, converting the straight-line flow trajectory into a spiral cyclone trajectory, greatly increasing the interlayer shear friction of the airflow, the collision friction times of the airflow with the air duct wall and the wind turbine blades, and improving the conversion ratio of kinetic energy to heat energy. The blade angle of the arc-shaped spoiler 307 can be designed to be consistent with the rotation direction of the wind turbine. The convex arc-shaped surface of the arc-shaped spoiler 307 will accelerate the cyclone speed of the airflow, and form a superposition effect with the centrifugal cyclone generated by the wind turbine, so as to improve the turbulence intensity in the air duct and significantly improve the friction heat generation efficiency. The arc-shaped spoiler 307 divides the V-shaped air duct 305, prolongs the residence time of the airflow in the V-shaped air duct 305, improves the compression sufficiency, and the temperature rise amplitude of the airflow is directly related to the working time in the air duct, that is, the longer the residence time, the more sufficient the compression friction. The arc-shaped spoiler 307 is equivalent to adding a flow guide resistance in the air duct. The airflow needs to bypass the arc-shaped convex of the spoiler to flow forward, and the movement path is significantly prolonged, so that the airflow does not directly pass through the air duct due to the too fast flow speed, and each part of the air can experience a complete cyclone compression process. The convex-to-concave structure of the arc-shaped spoiler 307 will form a periodic micro-compression area in the air duct. When the airflow flows through the convex part, the flow passage cross section becomes narrow, the flow speed increases, and the pressure rises, so that the air is compressed and generates heat. When the airflow flows through the concave part, the flow passage cross section becomes wide, the flow speed decreases, and the pressure decreases, forming a cycle of compression to expansion, and further strengthening the improvement of the internal energy of the air.

[0027] As shown in Figures 6 to 8 In order to realize the rapid installation of the exhaust fan 600, and to further improve the friction heat generation efficiency while forming a uniform annular negative pressure field at the air inlet 306, the fixing assembly 700 includes an annular plate 701, which is sleeved on the mounting roller 500. The mounting roller 500 is threadedly connected with a nut 702. The exhaust fan 600 is fixedly installed between the nut 702 and the annular plate 701 through the threaded connection between the nut 702 and the mounting roller 500. The exhaust fan 600 includes an annular shaft 601 and a plurality of fan blades 602 fixedly installed on the annular shaft 601. The fixing assembly 700 further includes a plurality of positioning blocks 703 fixedly installed on one side of the annular plate 701. The annular shaft 601 is provided with a plurality of positioning grooves 603 on one side. The positioning blocks 703 and the positioning grooves 603 are matched. The annular plate 701 is installed on the mounting roller 500, then the exhaust fan 600 is installed on the mounting roller 500 through the sleeve connection between the annular shaft 601 of the exhaust fan 600 and the mounting roller 500, and the rear end of the exhaust fan 600 is attached to the front end of the annular plate 701, and the positioning block 703 at the front end of the annular plate 701 coincides with the positioning groove 603 at the rear end of the annular shaft 601, so that when the mounting roller 500 drives the exhaust fan 600 to rotate, the annular shaft 601 and the mounting roller 500 do not slip, then the exhaust fan 600 is fixedly installed between the nut 702 and the annular plate 701 through the threaded connection between the nut 702 and the mounting roller 500, and when the wind wheel body 300 rotates clockwise, the exhaust fan 600 must rotate clockwise in the same direction, otherwise the airflow will collide, the rotational flow field of the main air duct will be damaged, the heat generation efficiency will be greatly reduced, the blades of the exhaust fan 600 rotating clockwise are bent towards the clockwise direction, so that after the airflow enters the blade bending channel, it is thrown towards the outlet along the bending direction, and the rotational flow direction of the main wind wheel is consistent, after the two rotational flows are superimposed, the airflow in the air duct forms a spiral strong turbulent flow, the friction frequency between the airflow and the wall surface of the air duct and the blades of the main wind wheel is greatly increased, the contraction and expansion effect of the V-shaped air duct 305 is amplified, the frequency and intensity of airflow compression are improved, and finally the proportion of mechanical energy converted into air internal energy is increased, and the hot air temperature rise is significantly increased. The design of the exhaust fan 600 is to strengthen the compression and friction process of the airflow through cooperative rotation, rather than simply increasing the air inlet.

[0028] Example two

[0029] As shown in Figures 6 to 11 In order to facilitate the quick disassembly and replacement of the wind wheel body 300, an installation hole 301 is formed at the center of the wind wheel body 300, and an elastic pad 704 is fixedly installed on one side of the annular plate 701; the mounting assembly 400 comprises a plurality of limiting plates 401, a moving sleeve 402 is sleeved on the mounting roller 500, the limiting plates 401 are arranged on the outer periphery of the moving sleeve 402, and the limiting plates 401 and the moving sleeve 402 are hingedly connected through the hinge plates 403; when the nut 702 fixes the exhaust fan 600, the exhaust fan 600 and the annular plate 701 are simultaneously moved towards the wind wheel body 300, the exhaust fan 600 is fixed, and at the same time, the moving sleeve 402 is driven to move forward by the elastic pad 704, and the limiting plates 401 are driven to move towards the inner wall of the installation hole 301; a plurality of sliding grooves 404 are formed in one side of the inner wall of the casing 100, a roller 405 is rotatably installed at one end of the limiting plate 401 through a bearing seat, and the roller 405 is slidably arranged in the sliding groove 404; a limiting groove 406 is formed in the inner wall of the installation hole 301, and the limiting plate 401 is matched with the limiting groove 406; When the exhaust fan 600 is installed, the exhaust fan 600 and the annular plate 701 are moved to the direction of the wind wheel body 300 through the threaded connection between the nut 702 and the threaded groove on the mounting roller 500. When the elastic pad 704 contacts the moving sleeve 402, the continuous movement of the nut 702 causes the elastic pad 704 to continuously move the moving sleeve 402 forward. Through the arrangement of the hinged plate 403, the moving sleeve 402 moves forward, driving the limiting plate 401 to move upward. In order to avoid excessive friction between one end of the limiting plate 401 and the inner wall of the shell 100, which causes the limiting plate 401 to be unable to move upward, a sliding groove 404 is opened in the inner wall of the shell 100, and a roller 405 is arranged at one end of the limiting plate 401 close to the inner wall of the shell 100. Through the connection between the roller 405 and the bearing seat, the friction between the limiting plate 401 and the inner wall of the shell 100 is reduced. With the continuous forward movement of the moving sleeve 402, the limiting plate 401 enters the limiting groove 406. Through the fit between the limiting plate 401 and the limiting groove 406, the slipping phenomenon between the wind wheel body 300 and the mounting roller 500 can be effectively prevented. When the limiting plate 401 coincides with the limiting groove 406, the annular plate 701 is no longer moved forward by the nut 702, so that the exhaust fan 600 is fixed between the annular plate 701 and the nut 702, and the wind wheel body 300 is fixed on the mounting roller 500. The expanded limiting plate 401 has a small radial fine adjustment capability. If the wind wheel body 300 is slightly eccentric during processing or has a deviation of 0.05-0.1mm during installation, the limiting plate 401 can automatically compensate by uneven expansion, so that the center of gravity of the wind wheel body 300 coincides with the center line of the mounting roller 500 as much as possible, reducing the centrifugal vibration source during high-speed rotation. Compared with the traditional integral rigid hub, the integral hub cannot be fine-tuned, and the coaxiality deviation will directly translate into severe vibration. The expanded multi-piece limiting plate 401 can reduce the radial swing by 30%-40%, indirectly improving the stability of the hot air heating efficiency. At the same time, the assembly and maintenance are more convenient, without the need for hot assembly and cold disassembly. The traditional interference fit requires heating the wind wheel body 300 or cooling the mounting roller 500 to disassemble and assemble, which is complex and easy to damage the parts. The expanded multi-piece limiting plate 401 is connected by mechanical expansion, i.e. tightening the nut 702 to achieve clamping or loosening. Disassembly and assembly do not require special temperature control equipment, and the maintenance time is shortened by more than 70%.

[0030] Referring to Figures 10 to 11As shown, in order to reduce the vibration amplitude between the wind wheel body 300 and the mounting roller 500, offset the coaxial error, the elastic layer 407 is fixedly installed on the top of the limiting plate 401, and the top of the elastic layer 407 is attached to the top of the limiting groove 406; the material of the elastic layer 407 is polyurethane elastomer, the elastic modulus of the polyurethane elastomer is moderate, which can compensate for the deviation and provide sufficient torque transmission friction, and is resistant to high temperature and wear, avoiding aging and failure of the elastic layer 407 due to heat generated by friction during high-speed rotation. By tightening the nut 702, the elastic layer 407 on the top of the limiting plate 401 is attached to and pressed against the top of the limiting groove 406. The turbulent airflow in the V-shaped air duct 305 will generate periodic impact load with large and small pressure on the arc-shaped plate 304. If this load directly acts on the rigidly connected shaft, it will cause resonance risk. The viscoelastic properties of the elastic layer 407 can absorb the energy of the load fluctuation, convert the periodic impact load with large and small pressure into smooth and continuous load, avoid the resonance of the wind wheel and the shaft, and maintain the rotation stability. When there is a small dynamic balance deviation in the wind wheel, or there is an error in the coaxiality during installation, the elastic layer 407 can compensate for the deviation by elastic deformation. When the wind wheel body 300 rotates at high speed, the centrifugal force generated by eccentricity will cause the elastic layer 407 to deform slightly in the eccentric direction, buffer the radial swing of the wind wheel body 300, and avoid the problem that the deviation is amplified into violent vibration under rigid connection. The traditional rigid connection will directly transmit the vibration of the wind wheel to the mounting roller 500 and the machine shell 100, while the elastic layer 407 acts as a damping pad to attenuate the transmission of vibration energy and reduce the vibration amplitude of the whole machine.

[0031] The above disclosure is only a few specific embodiments of the present application, but the embodiments of the present application are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present application.
