Description

Circulating pressurized ventilating compressor

The present invention relates to the field of air purification compression technology, and more particularly to a circulating pressurized ventilating compressor. .; Background technique

The axial flow fan used by people now has low wind pressure, poor ability to handle pollutants, high noise, high energy consumption and low efficiency. The centrifugal axial flow gas compressor used by people is complicated in structure, with many materials, heavy weight and supercharged effect. Poor, inefficient, energy-intensive, and narrow in use. Disclosure of invention

The object of the present invention is to provide a cyclone pressurized ventilation gas with a simple structure, less material consumption, light weight, strong ability to handle pollutants, good compression effect of compressed gas, high efficiency, low energy consumption, low noise, and wide application range. machine.

The present invention is achieved by the following technical solutions: A circulating supercharged ventilating compressor comprising an organic casing and a rotor, characterized in that the rotor is composed of a wind gear and a transmission shaft, and the wind gear is composed of a bushing, a wind gear plate and a wind tooth. The wind gear is connected with the drive shaft through the sleeve, the wind tooth is connected with the wind tooth plate through the tooth root of the wind tooth, the wind tooth is superposed by the multi-layer wind tooth blade, and the air tooth channel is provided between the wind tooth blade and the wind tooth blade. The wind tooth air passage is provided with a wind tooth air inlet and a wind tooth air outlet.

The circulating supercharged ventilating compressor is quite different from the existing old axial flow fan and centrifugal axial flow gas compressor. For the convenience of description and clear expression, there are several terms to explain here:

The rotor and the side walls of the body, which are directed by the central axis of the rotor, are called the axial side walls of the ventilating compressor and the axial side. The axial windward side of the wind gear (the axial air inlet side of the wind gear) is determined as the axial outer side of the wind gear (or the front axial side), and the other side of the corresponding wind gear is defined as the wind gear Inner side (or the rear axial side of the wind gear).

The wind tooth blade is radially close to the wind gear plate and is the root of the wind tooth blade, which is referred to as the tooth root; the radial end of the wind tooth blade is the top of the wind tooth, which is referred to as the tooth top; the wind tooth is near the root of the tooth is the lower part or bottom of the wind tooth; The tooth near the top of the tooth is called the upper part of the wind tooth, and the axial air inlet edge of the wind tooth is the leading edge of the wind tooth, and its axial direction The edge of the exhaust is called the trailing edge of the wind tooth.

Before and after the wind tooth: 'The forward swirling airflow is directed to the front and the backward swirling airflow is directed to the rear. The outer circumference of the wind gear is the radial edge of the wind gear, the axial side edge of the wind gear is the axial edge of the wind gear, and the axial edge of the wind gear is divided into the front axial edge of the wind tooth and the rear axial edge of the wind tooth.

The main structural component of the circulating supercharged ventilating compressor is the wind gear on the rotor. The ventilating compressor does not use the cylindrical casing and the front and rear axially stationary baffles, and the wind gear can generate the high pressure axial flow.

The wind gear is composed of a wind gear sleeve, a wind gear plate and a wind tooth. The wind gear plate is similar to the general I type axial fan axial flow gas compressor core, and the wind gear is connected to the wind gear plate.

A plurality of wind teeth are connected to the wind gear plate, and each wind tooth is superposed and superposed by a plurality of multi-layer wind tooth blades. The number of wind tooth blades of each wind tooth is equal, and the corresponding wind tooth blades have the same shape and size. There are wind-tooth air passages between the multi-layer blades, which means that the superimposed wind-toothed blades do not have two layers or layers attached together, and there must be a certain gap between each two-layer wind-toothed blades to facilitate The airflow passes through it. The wind tooth air passage, that is, the distance between the two layers of wind tooth blades, should be determined according to the requirements of use.

The air tooth inlet is located at the leading edge of the wind tooth, and the outlet is located at the trailing edge of the wind tooth, that is, the air flow can enter the wind tooth air passage from the air inlet end of the wind tooth front edge, and then the wind tooth flow from the exhaust end end of the wind tooth end. .

The wind tooth blade of each wind tooth shall not be less than two layers, and the wind tooth path of each wind tooth shall be at least one layer, for example: two layers of wind tooth blades constitute a layer of wind tooth air passage, and three wind tooth blades constitute two layers. The layer of wind tooth airway, the four-layer wind tooth blade constitutes a three-layer wind tooth airway, ...

When the wind tooth works, the gas is sucked into the air inlet of the wind tooth from the wind inlet end of the wind tooth, and the gas is sucked from the outer working surface of the air inlet end of the wind tooth, that is, the air tooth suction is double, so the whole The wind gear flow will be much larger, and the more the air tooth air level is, the larger the wind tooth suction.

More importantly, the gas entering the airflow of the wind tooth absorbs energy from the double-layer blades, and thus a higher wind pressure is obtained.

The purpose of the anti-leakage isolation plate on the top of the wind tooth of the present scheme is twofold: one is to prevent the gas of the air passage of the wind tooth from flowing out of the tooth top due to the centrifugal force, and flowing outside the wind gear; The wind gear can be reinforced, and the wind tooth blades can be spaced apart from each other to form a fixed form of wind tooth air passage. The leak-proof spacer should be light and not heavy, so it should be made of thin plates as much as possible. The wind tooth root of the solution can also be provided with a 3⁄4 tooth root support spacer, and the root support spacer is connected to the root of the wind tooth blade.

The pressurized air deflector may also be disposed in the air-tooth air passage of the present scheme, and the purpose of the pressurized air deflector is to make the airflow entering the air-tooth air passage flow through the wind-tooth air passage along the orbit determined by the pressurized air deflector. . In this way, the airflow through the airflow of the wind tooth can absorb energy from both side walls of the wind tooth and absorb energy from the pressurized air deflector, so that a higher wind pressure can be obtained, and the air pressure boosting guide can be obtained. The flow sheet must pass through the wind-tooth airway inlet (or near the air-tooth airway inlet) of the wind-tooth airway. This continuity can be straight, it can be diagonal, it can be linear or curved. The longitudinal edges of the air-pressure-assisted baffle are connected to the side walls of the air-toothed air. According to the need, a booster baffle can be set in one wind tooth channel, or more than two booster baffles can be set. The airway booster baffle can both obtain the boosting effect of the wind gear and obtain Reduce the noise effect. The airway pressure-adjusting baffle can be in a variety of different structural forms, such as a straight plate, a curved plate shape, a wing shape, etc., and the length of the airway pressure-adjusting baffle can be greater or smaller than the width of the air-tooth channel ( The distance from the leading edge of the wind tooth to the trailing edge can also be equal to the width of the air passage of the wind tooth.

In order to ensure that the wind gear has sufficient strength and sufficient rigidity, the technical solution can also provide a reinforcement rib on the wind gear, and the reinforcement rib is placed on the axial side of the wind gear, and the reinforcement lacing will make the whole wind The gear teeth are integrated into one, so that the entire wind gear can have better strength and rigidity.

In order to increase the wind pressure more effectively, the wind tooth air outlet of the first wind tooth of the technical solution is opposite to the air inlet of the next layer of the next wind tooth, so that the wind of the previous wind tooth is gas. The airflow exiting the channel exits into the next layer of the airfoil of the adjacent downstream wind tooth to continue processing pressure.

The more the wind tooth blade level of the whole wind gear, the more the air tooth air passage level, and the relevant wind tooth air passage outlet is opposite to the adjacent wind tooth air passage inlet, then the air flow entering the wind gear is pressurized. The more, the greater the increase in wind pressure. For example, if the wind gear air passage of the wind gear is two layers, the air flow entering the wind gear can be pressurized twice. The wind tooth air passage of the wind gear is three layers, and the air flow entering the wind gear can be three times. Pressure, ......, that is to say, the gas sucked in from the external surface of the wind tooth and the air inlet of the wind tooth can be processed and pressurized several times through the multi-level wind tooth air passage, so that the ventilation compressor can be obtained very high. Wind pressure. ' The wind tooth air outlet of the wind gear is opposite to the air inlet of the adjacent wind tooth, if it is the same level of air inlet and outlet, for example, let the first wind of the previous wind tooth The tooth air passage exits the first layer of the upstream air tooth channel of the adjacent one of the next wind teeth, and the second layer of the wind tooth air outlet of the previous wind tooth faces the second layer of the adjacent one of the next wind teeth Wind tooth airway inlet, ..., this structure is unable to make the wind gear exhaust airflow, the wind gear can not work normally, so it can not meet the purpose of multiple multiple pressurization.

In order for the wind gear to meet multiple multiple pressurization requirements, the wind gear air inlet and outlet of the wind gear must correspond to different levels. For example, the first layer of the air-toothed airway outlet of the previous wind tooth is opposite the second layer of the air-tooth airway inlet of the adjacent one of the next wind tooth, and the second layer of the air-toothed airway of the previous wind tooth is facing the phase The third layer of the wind tooth air inlet of the next wind tooth, ......, ,

Different levels of wind-tooth airway inlet and outlet correspond to each other, and there are many different ways of structure. For example, the trailing edge outlet of the front face of the previous wind tooth faces the first layer of wind tooth of the adjacent next wind tooth. Airway inlet, the first layer of wind tooth air passage exit of the previous wind tooth is opposite the second layer of wind tooth air passage inlet of the adjacent one downstream wind tooth, and the second layer of wind tooth air passage exit of the previous wind tooth pair The third layer of the air-toothed airway inlet of the adjacent one of the downstream wind teeth, ..., for example, the trailing edge outlet of the outer face of the previous wind tooth and the first layer of the air-toothed airway outlet facing the adjacent rear The second layer of the wind tooth of a wind tooth enters, the second layer of the air tooth channel of the previous wind tooth is opposite the inlet of the third layer of the air tooth channel of the adjacent one of the next wind tooth, ..., for example The first and second layers of the first airfoil of the first wind tooth are opposite to the third and fourth layers of the air flow of the adjacent one of the wind teeth, the third and fourth layers of the previous wind tooth The outlet of the wind tooth air passage is opposite to the fifth and sixth layer of the air inlet of the adjacent wind tooth, ..., Wait. In short, different levels of wind-tooth airway import and export corresponding methods have a variety of different structural forms. The specific structural form should be determined by the specific application requirements and the level of the air-tooth airway.

There are various ways to enter the wind gear, such as the wind inlet from the front edge of the wind tooth, the wind inlet from the wind tooth, or two three... the air inlet of the wind tooth inlet, from the wind. Wind gear external working surface air inlet end and wind tooth one wind tooth air passage inlet or two three... wind tooth air passage inlet simultaneously enter the wind, ......

There are also a variety of wind gear wind exhausting methods, such as exhausting air from the wind outlet at the trailing edge of the wind tooth external working surface, exhausting air from a wind tooth air passage outlet of the wind tooth, and the wind end from the trailing edge of the wind tooth external working surface. And a windy tooth The road or the air outlets from several wind-tooth air ducts simultaneously exhaust, ..., the direction of the exhaust can be tangential or axial.

The wind gear of the wind gear is composed of multi-level wind tooth blades, and the wind tooth air passage is multi-layered. And the wind tooth air passage exit of the previous wind tooth corresponds to different levels of the wind tooth air passage inlet of the adjacent one of the wind teeth, and the first layer of the wind tooth air passage of the wind gear of the wind gear is the wind tooth The effective air inlet, the air inlet direction is similar to the rotor rotation trajectory, and the wind layer air outlet of the wind tooth is the effective air outlet of the wind tooth, and the outlet direction may be the rotor tangential type or the rotor axial type. The second and third layers of the wind tooth...the inlet of the wind tooth air passage is the transition air inlet, and the inlet direction needs to be the first layer, the second layer, the third layer of the adjacent previous wind tooth... Corresponding to the exit of the road, the first, second and third layers of the wind tooth...the exit of the wind tooth air passage is the transition air outlet, and the exit direction is the second, third and the third of the adjacent one downstream wind tooth. The four-layer wind tooth air inlet is corresponding. .

The wind gear wind tooth of the technical scheme is formed by superimposing multi-level wind tooth blades, the wind tooth air passage is multi-layer structure type, and the wind tooth air passage inlet and outlet of the wind tooth are corresponding to different levels, then the wind tooth is The gas sucked in the air passage of the wind tooth can be processed several times, ten times, dozens of times of supercharging with the rotation of the rotor, and the gas can absorb energy from the double wall surface of the wind tooth blade in the air passage of the wind tooth. Pressure, so the pressure of the gas discharged from the effective air-tooth airway outlet at the end of the wind tooth will be very high. If the existing old centrifugal or axial flow gas compressor is used to process the gas, in order to make the gas sucked in the front end of the compressor to be supercharged several times, ten times, or several times, it must be several levels. More than ten stages and tens of stages of single-stage impellers are used in series, and a static rectification diversion facility must be added between the single-stage impellers in order to process the gas sucked by the gas compressor several times, ten times, dozens of times. Supercharged.

Compared with the existing old centrifugal axial flow gas compressor, the structure of the invention is extremely simple, can greatly save material and reduce weight, can greatly reduce friction and improve efficiency, save energy, and has wider application range, handling and installation. It is extremely convenient to use and maintain.

In the circulating supercharged ventilating compressor of the present invention, the wind tooth air passage outlet of the first wind tooth of the wind gear and the wind tooth air passage of the adjacent rear wind tooth can communicate with each other by means of the wind tooth air passage communicater. After the connection, the wind tooth air passage of the previous wind tooth and the wind tooth air path of the latter wind tooth become a unified wind tooth air passage. For example, the first wind tooth first airfoil airway outlet is connected to the second wind tooth airway inlet of the adjacent one downstream wind tooth, and the first wind tooth first layer wind tooth airway inlet is the communication. After the unified wind tooth The entrance of the road, the second air-toothed airway exit of the second wind tooth is the unified wind-tooth airway exit. If from front to back, the first layer of the air-toothed airway exit of the previous K-tooth is connected to the second layer of the air-toothed airway inlet of the next subsequent E-tooth, the second layer of the previous E-tooth The outlet of the wind-tooth airway is connected to the inlet of the third layer of the air-toothed airway of the next C-toothed tooth. The third layer of the air-toothed airway exit of the previous C-toothed tooth is adjacent to the adjacent one of the next D-toothed teeth. The four-layer air-toothed airway inlets are connected to form a unified wind-tooth airway. The first wind-toothed air-toothed airway inlet is the unified wind-toothed airway inlet, and the latter is a fourth-layered wind-toothed airway. The airway exit is the unified wind tooth airway outlet.

For example, the wind gear wind tooth is a five-layer wind tooth air passage exit and the inlet is connected to form a unified wind tooth air passage, then the first wind tooth first layer wind tooth air passage inlet is the unified wind tooth air passage inlet, The fifth layer of the wind tooth exit of the fifth wind tooth is the unified wind tooth airway outlet... In short, the wind tooth airway outlet and inlet connection method should be determined according to the actual use and the number of wind tooth air passage levels.

The air-tooth airway outlet is connected to the inlet to form a uniform wind-toothed airway. The wind-tooth airway can be a circular or circular arc. The air flow flows annularly around the wind gear disk in such an annular or curved air passage.

The air-tooth airway connector is placed between the two wind teeth, and the air channel inside the wind-tooth airway connector may be hierarchical, and the air channels of each layer are respectively connected with the corresponding air-tooth air passages of the front and rear wind teeth; The airway inside the airway connector can be the same cavity without layers, so that the cavity can communicate with different levels of wind tooth air passages of the front and rear wind teeth.

In order to further improve the supercharging effect and the supercharging efficiency of the ventilation compressor, the rotor of the present invention can simultaneously connect several wind gears in series, so that each airfoil air outlet of the first wind gear is combined with another or several other wind gears. Corresponding individual air-tooth airway inlets are connected or connected to each other, 'Let several wind gears and corresponding wind-tooth air passages be connected in series to form a uniform wind-tooth air passage. The first wind gears are connected in series with the air-tooth air passages. After the entire rotor is unified with the wind gear air tooth inlet, the last stage wind gear wind tooth effective exit (or axial or tangential) is the uniform wind gear wind tooth air passage exit of the entire rotor after series connection. Through such a structure, the gas of the wind gear rotor entering the wind gear air passage of the first stage wind gear can be obtained by rotating the same rotor for several weeks and passing through the multi-stage wind gear of the multi-stage wind gear to pressurize the machining, thereby obtaining More energy, resulting in higher wind pressure, the entire pressurization process is carried out in the same rotor in a uniform wind air duct, without adding any static deflector. The circulating supercharged ventilating compressor is corresponding to or connected to the inlet and outlet of the wind tooth air passage of different levels of wind gears, or the air inlet and outlet of several wind gears are connected, and different levels or different wind gears are connected in series. After forming a uniform air-tooth airway, the gas sucked in from the air inlet end of the wind tooth surface or the air inlet of the first layer wind tooth air can rotate with the wind gear rotor for one week or several weeks, and pass through the multi-level wind tooth air passage. By processing, more energy is obtained, and a higher wind pressure is generated. The entire pressurization process is performed in the wind gear of the same rotor without adding a static flow guiding device. It can be seen that the multi-stage wind gears are connected in series to form a pressurized supercharged ventilating compressor, which can also greatly simplify the structure, reduce materials, reduce weight and reduce aerodynamic friction area, which can greatly save resources and greatly improve efficiency, greatly save energy.

The inlet direction of the wind gear air passage of the cyclone pressurized ventilating compressor of the present invention is slightly opposite to the direction of the rotor steering (or 曰 is substantially consistent with the steering of the rotor). The wind tooth air passage may be in a variety of different structural forms, such as a longitudinally expanded shape, a contracted shape, an equal cross-sectional shape, etc., and the inner diameter of the wind tooth may be circular, square, curved, oblate, or the like. The wind tooth outlet can be tangential or axial.

The invention adopts three kinds of supercharging working principles to process the gas respectively, that is, the working principle of the pressurizing force pressurization working principle, the working principle of the rotating force pressurizing, and the working force of the pressing force of the pressing force to jointly pressurize the working principle.

As a general low-pressure circulating supercharged ventilating compressor, it can be used with a simple stamping force boosting working principle and a simple rotating force boosting working principle. The ventilation compressor adopts a single-stage wind gear structure. The wind gear wind tooth blade structure structure does not have to be too much, and the wind tooth air passage layer does not have to be too much. The wind tooth air passage is connected to form a uniform wind tooth air passage. , less than or equal to the circumference of the rotor is fine. It is generally circular, and it occupies a part of the entire circumference. The wind gear outlet is axial (which can also be tangential to the rotor). In this structural form, if the inlet direction of the wind tooth air passage is opposite to that of the rotor, the gas is processed by a simple working principle of the punching force. During operation, the rotor rotates, and the gas is steered into the air passage of the wind from the inlet of the air-toothed air passage. Since the flow direction is opposite to the direction of movement of the side wall of the air-toothed air passage, the energy can be continuously absorbed and compressed and pressurized. In this structural form, if the inlet direction of the wind tooth air passage is the same as that of the rotor, the gas is processed by a simple rotary force boosting working principle. The air-toothed airway is longitudinally expanded (or isolated by the wind-toothed airway pressure-adjusting baffle). When working, the rotor rotates, generating a pumping force at the front end of the air-tooth airway inlet, directly to the outside. The gas is sucked into the air passage of the wind tooth. Since the gas flow direction is the same as the direction of the side wall of the wind tooth air passage, energy can be continuously obtained and accelerated. Since the air passage of the wind tooth is longitudinally expanded, the gas can be continuously decelerated and diffused, and finally a higher wind pressure is obtained.

As a high pressure or ultra high pressure compressor compressor, the present invention can use a simple rotary force boosting working principle and a punching force rotating force to jointly pressurize the working principle. The machine should adopt a single-stage multi-level wind tooth blade multi-level wind tooth air passage or multi-stage wind gear series structure. A single-circular air-toothed airway with a one-week cycle or a multi-circular air-toothed airway with a flow of several weeks. The air-tooth airway outlet may be tangential or axial, and the annular air-toothed air passage may be expanded, contracted, or equally shaped.

In the structural form, if the flow direction of the wind tooth air passage in the front part of the rotor is opposite to that of the rotor, the flow direction of the wind tooth air passage in the rear part of the rotor is in the same direction as the steering of the rotor. This type of structure should be combined with the pressing force and the rotating force. principle. During operation, the rotor rotates, and the gas is steered from the rotor front air inlet of the rotor to the rotor in the front air duct of the rotor. Since the flow direction is opposite to the direction of the side of the rotor air passage in the front of the rotor, it can be continuously absorbed. The energy is compressed and pressurized. The gas flows through the front air duct of the rotor and then flows through the rotor and then flows directly into the rotor. The air passage of the wind tooth flows in the same direction as the rotor. At this time, the pressure energy is obtained by the rotating force. Since the flow direction of the gas in the air passage of the rotor at the rear of the rotor is the same as the direction of movement of the side wall of the air duct and the booster vane of the wind tooth air passage, the energy can be continuously absorbed and accelerated.

In this type of structure, there are three technical measures to change the flow direction of the front airflow of the airflow in the front of the wind, so that it flows downstream into the wind path of the wind and the rotor is continuously flowing to obtain energy. The front air inlet of the rotor is connected to the air inlet of the rotor at the rear of the rotor through the air-tooth air passage connector. Thus, the airflow from the air outlet of the rotor at the front of the rotor passes through the air-tooth air passage connector. Naturally, it is commutated to introduce the rear airfoil air passage of the rotor and turn to flow along the rotor.

The second is to install a reversing deflector between the outlet of the rotor at the front of the rotor and the inlet of the air duct of the rear of the rotor (both stationary and rotating), and change the airflow at the outlet of the rotor at the front of the rotor through the revolving deflector. Flow direction.

Thirdly, it mainly refers to the rotor used in series with multi-stage wind gears. The rotor used in series with multi-stage wind gears adopts the method of two-axis series connection, that is, the wind gear at the front of the body and the wind gear at the rear of the body. Do not use two concentric drive shafts to drive the reverse rotation. In this way, the airflow turns to the counter-winding gear in the air-tooth air passage at the front of the body, and the pressure energy is obtained by the punching force. The airflow flows into the wind-tooth air passage at the rear of the body and turns to flow, and the pressure energy is obtained by the rotating force.

The invention is used as a high-pressure extra-high pressure compressor compressor. If the flow direction of the wind-tooth air passages in front and rear of the rotor is in the same direction as the rotor, the inlet direction of the wind-tooth air passage of the rotor is also in the same direction as the rotor steering. In the rotor, the gas is processed by a simple rotating force. During operation, the rotor rotates, that is, a negative pressure can be generated in the rotor air passage and the inlet of the wind tooth air passage, and the outside air is directly sucked into the air passage of the wind tooth. Since the flow direction of the gas coincides with the direction of movement of the side wall of the air passage of the wind tooth, the energy can be continuously obtained and accelerated.

In this type of structure, if a fan is added to the front end of the rotor or the rear-flow fan impeller directly blows into the air inlet of the wind tooth, the effect is better.

The circulating positive pressure ventilating compressor rotor of the present invention is driven by a motor or other diesel engine, a gasoline engine, a gas turbine, a steam turbine or the like.

The circulating supercharged ventilating compressor is widely used as a general ventilator. It has a simple structure, saves materials, is light in weight, is energy efficient, and is suitable for use in a variety of ventilation and air supply occasions. As a high pressure or ultra high pressure compressor compressor, it is superior to various centrifugal compressors, axial compressors and Roots blowers because of its simple structure, light weight, high efficiency and energy saving. It is suitable to replace various special compressor compressors. It is especially suitable for use in compressors that replace aircraft engines such as various vehicles, ships, and airplanes.

The best way to implement the invention

Embodiment 1, referring to Figures 1, 2, 3, a circulating supercharged ventilating compressor, comprising an organic casing 1, a rotor 2, a wind gear 3, a drive shaft (motor shaft) 4, a wind gear bushing 5, a wind gear The disk 6, the wind tooth 7, the wind gear plate 6 is connected with the wind gear sleeve 5, and the wind tooth 7 is connected by the wind tooth root 8 to the wind gear plate 6. The four wind gears are composed of two curved thin iron plate wind teeth. The blades 9 are superposed, and the wind tooth blades 9 are provided with a wind tooth air passage 10, and the wind tooth air passage 10 is provided with a wind tooth air passage inlet 11 and a wind tooth air passage outlet 12, and the wind gear 3 is provided on both axial sides. a circular reinforcing rib 25, a reinforcing rib 25 and a spur blade are welded to each of the spur blades 9, the wind gear plate 6 is cylindrical, the wind tooth root 8 is welded to the wind gear plate 6, the wind gear 3 is connected to the drive shaft 4 of the motor 24 via a wind gear bushing 5. Wind tooth As the front edge air inlet 21 direction and the wind tooth air passage inlet 11 direction, the wind gear is turned slightly, and the wind tooth working surface trailing edge air outlet 22 direction and the wind tooth air passage outlet 12 direction are both axial directions.

The machine uses a simple stamping force boosting working principle to process the gas. During operation, the gas enters the wind tooth surface from the front axial side (the motor side), and the wind tooth working front edge air inlet 21 and the wind tooth air inlet 11 In the face and the air-toothed air passage 10, the wind gear is then axially discharged from the trailing edge air outlet 22 and the air-tooth air passage outlet 12 of the wind tooth working surface. In the work, the wind inlet 21 and the air inlet 11 are in the wind, so the air volume is large, and the direction of the gas flowing into the air passage is opposite to the direction of the air passage 10 of the wind tooth. It can continuously absorb energy and be compressed and pressurized, so its wind pressure is relatively high. '

'In this case, the air intake is double, and the supercharging is also double. Compared with the conventional old axial fan, the air volume is large and the wind pressure is high. No need to add intermediate static diversion facilities, the first-stage wind gear can be used in two stages of the old axial fan, which is small in size, less in material consumption, and energy efficient.

This example is adapted to be used in a variety of ventilation and airflow axial fans.

This example can be used as a ducted blower blower. If the enclosure is removed (only a shield is added outside the rotor), it can be used as a general ventilator.

Embodiment 2, referring to Figures 4, 5, 6, This example is basically the same as Example 1, except that the wind tooth of this example is formed by superimposing three layers of wind tooth blades, and the air tooth channel 10 is two layers, the former one. The first layer of the air-toothed airway outlet 12 of the wind tooth corresponds to the second layer of the air-tooth airway inlet 11 of the adjacent one of the following wind teeth, as shown in Fig. 4 and Fig. 5, the first layer of the first tooth of the wind tooth The exit of the passage is a transitional exhaust vent, corresponding to the second layer of the air-toothed airway inlet 11 of the adjacent one of the downstream wind teeth, and the second layer of the air-toothed airway outlet 12 of the preceding wind-tooth is effectively exhausted to the outside by the wind-toothed tooth The outlet direction is the axial direction; the first wind tooth first airfoil airway inlet is the externally effective suction port of the wind tooth, the inlet direction is slightly intersected with the wind gear steering, and the first wind tooth second layer wind tooth gas The inlet of the road is a wind-tooth transition air inlet, and the inlet direction corresponds to the first layer of the wind tooth outlet of the adjacent previous wind tooth. That is to say, the gas sucked in by the first layer of the first air-tooth airway inlet 11 is processed and then discharged to the second layer of the air-toothed air passage of the latter wind tooth, and then processed by the second layer of wind-toothed gas. The road outlet discharges the wind gear 3 to the outside. The second difference is that the bottom of the wind tooth of this example is provided with a root support spacer 13 which supports the root of the wind tooth impeller. The third difference is that there are two pressurized baffles 16 in each layer of the air-toothed air passage of this example. In this case, the gas is processed using a simple stamping force working principle. 'When working, the gas sucked in by the first layer of the air-toothed air inlet 11 and the front of the wind-toothed front air inlet 21 is decelerated and pressurized, and then discharged to the second layer of the air-toothed air passage to decelerate and then be discharged. tooth. That is to say, the gas sucked in by the wind tooth is supercharged and decelerated twice, the supercharging effect is good, and the efficiency is high. Due to the action of the pressurized baffle, the contact area of the gas in the air passage of the wind tooth is large, and the energy absorbed is much, so the supercharging effect is better.

This example can be used as a high-pressure pipeline blower for air supply. If the case is removed, it can be used directly as a ventilation ventilator.

Embodiment 3 Referring to Figures 7, 8, 9, and 10, this example is basically the same as Example 2, except that the wind tooth 7 of this example is formed by stacking 5 layers of wind tooth blades 9 and the air path of the wind tooth is four layers.

The second difference is that the wind gear 7 and the wind tooth 7 of the wind gear of this example are provided with a wind tooth air passage connector.

17 . The wind-tooth airway connector 17 is formed by superimposing a wind-toothed connector blade 9 ′ made of five thin iron plates, and the air-toothed air passage 10 ′ is a four-layer wind tooth that communicates with the front and rear two wind teeth respectively. Airway import and export. As shown in Fig. 8 and Fig. 10, the air inlet and outlet of the first air passage of the air-tooth air passage connector 17 are respectively connected to the second layer of wind-tooth gas of the first wind tooth 7 and the first wind tooth 7 The second air channel inlet and outlet of the second air passage of the wind tooth air passage connector 17 is respectively connected with the second layer of the air tooth channel of the previous wind tooth and the third layer of the air tooth channel of the latter wind tooth; The third layer air passage inlet and outlet of the device 17 are respectively connected with the third layer of the wind tooth channel of the previous wind tooth and the fourth layer of the air tooth channel of the latter wind tooth. The fourth layer of the airfoil of the previous wind tooth outlet 12 is the external effective air outlet of the wind tooth (axial type), and the first layer of the air tooth inlet 11 of the latter wind tooth is the external effective air suction port of the wind tooth. Each adjacent wind tooth and its intermediate air-tooth airway connector are arranged in this manner. The second difference is that the wind tooth tip of this example is provided with a leak-proof spacer 15 .

During operation, the airflow is sucked into the gas from the first layer of the first air-tooth airway inlet 11 of the first wind tooth through the first layer of the air-toothed air passage and then through the first air passage of the wind-toothed airway connector, and then into the latter wind tooth The second layer of the air-toothed airway passes through the latter wind-tooth airway connector 17 and enters the third layer of the air-toothed airway of the latter, and then passes through the latter air-toothed airway connector 17 to enter the next wind. The fourth layer of the tooth air passage of the tooth is finally discharged to the wind tooth in the axial direction by the fourth layer of the wind tooth air passage outlet of the wind tooth. The airflow is exhausted by the first air channel inlet of the wind tooth and the fourth air channel of the wind tooth. Due to the wind tooth, the whole process is that the gas rotates with the rotor for one week, that is, the gas sucked in by the air inlet of the wind tooth One week's accelerated pressurization process, so the wind pressure at the exit of the wind tooth is very high. Since the wind tooth tip is provided with the leakage preventing partition 15, the gas entering the air passage of the wind tooth during operation does not radially discharge the air passage of the wind tooth due to the centrifugal force. The gas sucked in by the effective air inlet of the wind tooth can be processed and pressurized by flowing through the air passage of the wind tooth. ,

The wind-tooth airway connector 17 of this example can also be made into an empty box type, that is, the entire air-toothed air passage 10' is not hierarchical, and the wind-tooth air passages of the two adjacent wind teeth are fed through the wind tooth. The air passage connectors 17 correspond to each other in the inner cavity. Referring to Fig. 10, this can cause the airflow to rotate inside the wind gear for one week and undergo supercharged processing to obtain a higher wind pressure. This structure is also suitable for use as a high pressure compressor.

In this case, the casing can be added or the casing can be used to make a high-pressure ultra-high pressure compressor.

Embodiment 4 Referring to Figures 11, 12, 13, this example is basically the same as Example 3 except that the two rotor gears are connected in series to form the same rotor. The first stage wind gear and its wind gear wheel and the second stage wind gear and the wind gear wheel are cylindrical, and the two stages of wind gear plates are connected in series to form a unified cylindrical wind gear disk 4, The graded wind teeth are connected in series to form a unified cylindrical ventilator rotor.

The second difference is that there is a wind tooth reversing deflector 18 between the two stages of the wind gears of the present embodiment, and a revolving flow communication device 19 is provided between the two stages of the corresponding wind tooth air path connecting device 17 .

The first layer of the air-toothed airway inlet 11 of the first wind gear of the first stage wind gear of this example is in communication with the outside, and the wind tooth air passage outlet 12 is adjacent to the first air passage of the wind tooth air passage connector. The second layer of the wind tooth is connected to the second layer of the wind tooth, and the second layer of the first tooth of the wind tooth passes through the second layer of the wind tooth channel and the third layer of the wind tooth. The air tooth channel is connected. The third layer of the air-toothed air passage of the first wind gear of the first stage wind gear communicates with the fourth layer air path of the first stage wind gear wind tooth through the third layer air passage of the wind tooth air passage connector 17, the wind The fourth layer of the toothed airway outlet 12 of the tooth is in communication with the inlet of the wind gear reversing deflector 18 via a reversing flow communication.

The air passage inside the wind tooth air passage connector 17 of the second stage wind gear is also divided into four levels, and the first layer of the wind tooth air passage inlet 11 of the previous wind tooth of the second stage wind gear passes through the revolving guide flow communicater 18 is connected to the outlet of the wind tooth reversing deflector 18, and the wind tooth air passage outlet 12 communicates with the second wind tooth air passage inlet of the second wind tooth. The second layer of the air-toothed air passage of the wind tooth communicates with the third layer of the air-tooth air passage of the latter wind tooth through the wind-tooth air passage connector 17, and the third layer of the air-tooth air passage of the wind tooth passes through the air-tooth air passage The communicating device 17 is in communication with the fourth layer of the wind tooth passage of the latter wind tooth, and the fourth layer of the wind tooth outlet 12 of the wind tooth It is an effective discharge port for the second stage wind gear. The effective discharge port of the wind gear is also the final effective discharge port of the entire rotor.

In this example, the stamping force and the rotating force are used together to work together to process the gas. During operation, the motor drives the rotor to rotate, and the first-stage wind gear effectively sucks in the air inlet. The flow of gas in the first-stage wind gear air-tooth air passage is opposite to that of the wind gear. The gas relies on the punching action in the first-stage wind gear air-tooth air passage. When the pressure is increased, the airflow is decelerating. After the airflow flows out of the fourth layer of air-tooth air passages of the first-stage wind gear wind teeth, the air-flow reversing deflector 18 is reversing into the first layer of air-tooth air passages of the wind teeth of the second-stage wind gear. At this time, the airflow will accelerate the flow by the action of the rotating force, and then accelerate the supercharged flow through the second layer, the third layer, the fourth layer of the wind tooth air passage of the second wind gear tooth through the wind tooth air passage connector 17. Then, the fourth stage wind gear outlet 12 of the wind tooth flows out of the second stage wind gear, that is, finally flows out of the ventilating compressor rotor.

Throughout the working process, the airflow is flushed into the first stage wind gear by the first air gear effective air inlet, and then discharged by the second stage wind gear fourth layer wind tooth air passage outlet. The gas is pressurized in a two-week process in the rotor of the ventilating compressor, so that the wind pressure is high.

In this case, there is no special thick casing, only a simple and light rotor shroud can be used to ensure high pressure gas, and the high pressure gas obtained is discharged from the body outlet rectifier.

: This example is adapted for use as a UHV gas compressor.

Embodiment 5, referring to FIG. 14, this example is substantially the same as the example 4, and a static reversing deflector 20 is added at the outlet of the first stage wind gear of the present example, and the first stage wind gear is sucked in and the processed gas is After the wind gear is exhausted, the second stage wind gear is introduced by the static reversing deflector, and the second stage wind gear is processed by the rotating force. Finally, the second stage wind gear wind tooth fourth layer wind tooth The airway outlet exits the rotor. The airflow enters the rotor from the first layer of the wind gear air inlet of the first stage wind gear. After two weeks of processing and pressurization, the gas can obtain high pressure energy.

This example is adapted for use as a UHV gas compressor.

Embodiment 6 Referring to Figure 15, this example is basically the same as Example 4, except that the drive shaft of this example is different.

4 is not the same shaft, the first stage wind gear and the second stage wind gear are respectively driven by two concentric shafts, and the two transmission shafts are turned opposite. The first-stage wind gear turns to the opposite direction of the airflow in the air-tooth air passage, and relies on the pressurization to pressurize. The second-stage wind gear is turned in the same direction as the air flow in the air-tooth air passage. Pressurized by the rotating force.

During operation, the airflow is getting lower and lower in the first-stage wind tooth air passage, but when it flows into the second-stage wind gear air-tooth air passage, the speed can be gradually increased by the action of the rotating force, and finally the second-stage wind The gear effective air tooth air passage outlet is discharged to the wind gear. The gas is introduced into the rotor by the first-stage wind gear effective wind-tooth air inlet, and is processed and pressurized by the two-week process, and finally used by the body convergence and rectification facility.

This example is adapted for use as a high pressure or extra high pressure gas compressor.

The air blower fan 23 is provided. When working, the fan directly supplies air to the first-stage wind gear air-tooth air passage. Since the fan and the two-stage wind gear are driven by the same drive shaft, the air flow is followed by the same transmission in the rotor. The shaft turns to rotate and continuously absorbs energy and increases pressure. It is obvious that the circulating plenum ventilator of this configuration increases the pressure with a simple rotational force.

'This example is suitable for use as a UHV compressor.

Embodiment 8, a circulating supercharged ventilating compressor (refer to FIG. 16), this example and the example 7 are the same, except that the rotor front end does not have a fan, and the rotor wind tooth air passage inlet direction is in the same direction as the rotor steering, the rotor High-speed rotation, negative pressure can be generated at the effective air inlet on the front side of the first-stage wind gear, direct suction gas enters the air-tooth air passage, and then continuously pressurizes the pressure to reach the rotor air-tooth air passage exit.
