有益效果Beneficial effect
本发明只需单独一个驱动装置就能够同时驱动液体和气体的流动及混合，无需其他设备驱动液体或气体。本发明通过锥形管和风扇的同步旋转，锥形管的旋转使液体由下向上输送并将液体经锥形管管壁的通孔甩至气液混合通道，风扇的旋转使气流在气液混合通道内由下向上输送，从而实现气液共轴输送和混合。本发明只需一个驱动电机就能够实现气体和液体的输送，能够大大节省成本。The invention only needs a single driving device to simultaneously drive the flow and mixing of liquid and gas, and no other equipment is needed to drive the liquid or gas. The invention uses the synchronous rotation of the conical tube and the fan. The rotation of the conical tube causes the liquid to be transported from the bottom to the top, and the liquid is thrown to the gas-liquid mixing channel through the through holes of the conical tube wall. The rotation of the fan makes the air flow in the gas-liquid The mixing channel is conveyed from bottom to top, so as to realize gas-liquid coaxial conveying and mixing. The invention can realize gas and liquid transportation with only one driving motor, and can greatly save cost.
本发明通过锥形管的旋转运动，利用斜面的离心力在垂直方向的分量对液体产生向上的力，同时本发明还利用了锥形管持续旋转所形成的流体效应，使液体形成向上的流体动力，从而实现液体由低向高的输送。The present invention uses the vertical component of the centrifugal force of the inclined plane to generate upward force on the liquid through the rotating movement of the conical tube. At the same time, the present invention also uses the fluid effect formed by the continuous rotation of the conical tube to make the liquid form upward hydrodynamic force. , So as to realize the liquid transportation from low to high.
进一步地，本发明还利用了锥形管内壁的倾斜叶片，将具有向上运动力的水进一步向上引导，最终到达锥形管的顶部，从而实现液体的输送。本发明的液体输送方式摆脱了对水泵的依赖，而是通过简单机械实现，因此彻底解决了噪音的困扰。Furthermore, the present invention also utilizes the inclined blades on the inner wall of the tapered tube to further guide the water with upward movement force upwards, and finally reach the top of the tapered tube, so as to realize liquid transportation. The liquid delivery method of the present invention gets rid of the dependence on the water pump, but is realized by simple machinery, thus completely solving the problem of noise.
本发明在锥形管上开设有多个通孔，并使锥形管沿高度方向的任意位置至少分布有一个通孔，当锥形管旋转时，能够使锥形管的每一个高度处都有水射出，从而在锥形管***的混合通道内分散形成均匀而密集的雨丝，有利于气体与液体的混合。本发明的锥形管对水的分散能力取决于锥形管上沿高度分布的通孔的直径和数量，而锥形管对水的分散能力能够决定加湿效率或者空气处理效率。In the present invention, a plurality of through holes are opened on the tapered tube, and at least one through hole is distributed at any position of the tapered tube along the height direction. When the tapered tube is rotated, the tapered tube can be made at every height Water is ejected to form uniform and dense raindrops in the mixing channel on the periphery of the tapered tube, which is beneficial to the mixing of gas and liquid. The water dispersion ability of the tapered tube of the present invention depends on the diameter and number of the through holes distributed along the height of the tapered tube, and the water dispersion ability of the tapered tube can determine the humidification efficiency or the air treatment efficiency.
本发明所采用的气液混合方式，能够使得电机在带动风扇旋转产生气流的同时，锥形管也与之同时旋转，显然电机的转速能够同时决定气流的流速和锥形管的旋转速度，锥形管的旋转速度越大则气流的流速越大，所产生的风量也越大，因此本发明中锥形管的转速与气液混合效率之间非线性关系，而是呈指数型上升，因此本发明的锥形管只需有几百转/分钟，就能够实现高效的气液混合功能。The gas-liquid mixing method adopted by the present invention enables the motor to drive the fan to rotate to generate air flow, and at the same time the conical tube rotates with it. Obviously, the rotation speed of the motor can determine the flow rate of the airflow and the rotation speed of the conical tube at the same time. The greater the rotation speed of the shaped tube, the greater the flow rate of the airflow, and the greater the air volume generated. Therefore, the non-linear relationship between the rotation speed of the tapered tube and the gas-liquid mixing efficiency in the present invention increases exponentially. The tapered tube of the present invention only needs a few hundred revolutions per minute to realize an efficient gas-liquid mixing function.
本发明结构简单可靠，且对精密度要求不高，易于生产和制造。The structure of the invention is simple and reliable, does not require high precision, and is easy to produce and manufacture.
本发明对转速要求不高，600转/分钟以上即可使用，无需配备专门电机，可与其他设备共用动力，甚至可以使用风力或人力。The invention does not require high speed, and can be used above 600 revolutions per minute. It does not need to be equipped with a special motor, can share power with other equipment, and can even use wind power or manpower.
本发明运行温和，能耗低，噪音小，外形体积小，特别适用于家庭及空间狭小和要求静音的场合。The invention has mild operation, low energy consumption, low noise, and small appearance and volume, and is especially suitable for homes and occasions where the space is narrow and silence is required.

外筒6的长度小于锥形管1，以使锥形管1的小端从下方伸出外筒6；The length of the outer tube 6 is smaller than that of the tapered tube 1, so that the small end of the tapered tube 1 extends out of the outer tube 6 from below;
外筒6可以是直筒，也可以是锥形筒或弧形筒；外筒6的横截面可以为圆形或多边形；外筒6的任一横截面的内径均比锥形管1的外径大，以使外筒6与锥形管1之间沿径向形成气液混合空间。The outer cylinder 6 can be a straight cylinder, a conical cylinder or an arc-shaped cylinder; the cross section of the outer cylinder 6 can be circular or polygonal; the inner diameter of any cross section of the outer cylinder 6 is greater than the outer diameter of the conical tube 1 Large, so that a gas-liquid mixing space is formed between the outer cylinder 6 and the tapered tube 1 in the radial direction.
作为一优选实施例，锥形管1的内壁固定设置有一个或多个沿纵向延伸的叶片2；多个叶片2中的任意两条均不会发生干涉；叶片2可以直接固定在锥形管1的内壁上，如采用塑料将锥形管1和叶片2通过模具一体注塑而成，如图4a、图4b所示；或者叶片2固定设置于沿纵向穿设于锥形管1内腔的叶片固定轴上，且叶片2紧贴于锥形管1的内壁，此时锥形管1可以采用金属（如不锈钢），将锥形管1与叶片2通过挤压或者其它方式实现二者之间的固定连接，如图4c所示；即叶片2与锥形管1可以是一体成型，也可以是分体式；叶片固定轴与上轴4和下轴5可以合并成为一根贯通轴；As a preferred embodiment, the inner wall of the tapered tube 1 is fixedly provided with one or more blades 2 extending in the longitudinal direction; any two of the plurality of blades 2 will not interfere; the blades 2 can be directly fixed on the tapered tube On the inner wall of 1, for example, the tapered tube 1 and the blade 2 are integrally formed by injection molding of plastic, as shown in Figure 4a and Figure 4b; The blade is fixed on the shaft, and the blade 2 is close to the inner wall of the tapered tube 1. At this time, the tapered tube 1 can be made of metal (such as stainless steel). The fixed connection between the blades is shown in Figure 4c; that is, the blade 2 and the tapered tube 1 can be integrally formed or separated; the blade fixed shaft and the upper shaft 4 and the lower shaft 5 can be combined into a through shaft;
由于叶片2突出于锥形管1的内壁，当锥形管111浸入液体时，能够使锥形管111的内壁形成一层液膜；同时，叶片2还能够减少液膜与锥形管1之间的相对滑动摩擦力，从而提高液膜的旋转速度，使液膜与锥形管1同步旋转；叶片2的高度决定了附着于锥形管1内表面的液膜厚度；优选地，叶片2的高度不小于锥形管1的壁厚。Because the blade 2 protrudes from the inner wall of the tapered tube 1, when the tapered tube 111 is immersed in liquid, a liquid film can be formed on the inner wall of the tapered tube 111; at the same time, the blade 2 can also reduce the difference between the liquid film and the tapered tube 1. The relative sliding friction force between them increases the rotation speed of the liquid film and makes the liquid film rotate synchronously with the tapered tube 1. The height of the blade 2 determines the thickness of the liquid film attached to the inner surface of the tapered tube 1; preferably, the blade 2 The height of is not less than the wall thickness of the tapered tube 1.

The inner cavity of the tapered tube 111 is provided with a through shaft along the axial direction. The upper end of the through shaft serves as the upper shaft 41 from the cone The top of the shaped tube 111 protrudes, and the lower end of the penetrating shaft is used as the lower shaft 51 to protrude from the bottom of the tapered tube 111;

贯通轴的中段作为叶片固定轴固定设置有多个螺旋形叶片2，叶片2紧贴锥形管111的内壁，使得叶片2与锥形管111成为一个整体；螺旋叶片的旋向为右旋，贯通轴的旋转方向为逆时针旋转，从而使液体由下向上输送；A plurality of spiral blades 2 are fixedly arranged in the middle section of the through shaft as a blade fixing shaft, and the blades 2 are close to the inner wall of the tapered tube 111, so that the blades 2 and the tapered tube 111 become a whole; the spiral blades have a right-handed direction. The direction of rotation of the through shaft is counterclockwise, so that the liquid is transported from bottom to top;
锥形管111的管壁上开设有多个通孔；上轴41固定连接风扇71；锥形管111的外部套设有外筒61，外筒61固定设置于外部支架上，使锥形管111能够相对于外筒61作旋转运动；The tube wall of the tapered tube 111 is provided with a plurality of through holes; the upper shaft 41 is fixedly connected to the fan 71; 111 can rotate relative to the outer cylinder 61;
外筒61的轴线与锥形管111的轴线重合；The axis of the outer cylinder 61 coincides with the axis of the tapered tube 111;
外筒61为上小下大的锥形管。The outer cylinder 61 is a tapered tube with a small top and a large bottom.
本发明采用锥形的外筒61，能够使外筒的上端61与风扇71之间形成顺畅的气流通道，有利于增加气液混合效果。The present invention adopts a tapered outer cylinder 61, which can form a smooth air flow channel between the upper end 61 of the outer cylinder and the fan 71, which is beneficial to increase the gas-liquid mixing effect.
本发明气液混合方法，包括以下步骤：The gas-liquid mixing method of the present invention includes the following steps:
将锥形管111的小端浸入液体中，锥形管111的大端位于液面的上方，使液体从开设于锥形管111小端的液体入口进入锥形管111的内腔；外筒61的底端位于液面以上，使外筒61与液面之间形成有间隙；The small end of the tapered tube 111 is immersed in the liquid, and the large end of the tapered tube 111 is located above the liquid surface, so that the liquid enters the inner cavity of the tapered tube 111 from the liquid inlet opened at the small end of the tapered tube 111; the outer cylinder 61 The bottom end is above the liquid level, so that a gap is formed between the outer cylinder 61 and the liquid level;
驱动机构通过上轴41或下轴51带动锥形管111及风扇71同步旋转；在锥形管111的旋转过程中，锥形管111内腔的液体在离心力F1的作用下被甩向锥形管1的内壁，锥形管111的内壁给予液体一个反作用力F2，由于锥形管111的内壁与垂直方向成一夹角α，因此反作用力F2与水平方向成一夹角α，该反作用力F2具有沿垂直方向的分量F 2T和沿水平方向的分量F 2P，该垂直分量F 2T使得液体能够沿锥形管111的内壁向上运动，如图9所示； The driving mechanism drives the tapered tube 111 and the fan 71 to rotate synchronously through the upper shaft 41 or the lower shaft 51; during the rotation of the tapered tube 111, the liquid in the inner cavity of the tapered tube 111 is thrown to the cone under the action of centrifugal force F1 The inner wall of the tube 1, the inner wall of the tapered tube 111 gives the liquid a reaction force F2. Since the inner wall of the tapered tube 111 forms an angle α with the vertical direction, the reaction force F2 forms an angle α with the horizontal direction. The reaction force F2 has A component F 2T in the vertical direction and a component F 2P in the horizontal direction. The vertical component F 2T enables the liquid to move upward along the inner wall of the tapered tube 111, as shown in FIG. 9;
当液体在旋转的过程中接触锥形管111内壁的叶片时，倾斜的叶片2能够向液体进一步提供向上的推力，推动液体继续向上运动；同时，倾斜的叶片2还能够向液体提供一横向力，使得液体能够横向运动，从而能够使液体遍布锥形管111的内壁；When the liquid contacts the blades on the inner wall of the tapered tube 111 during the rotation, the inclined blades 2 can further provide an upward thrust to the liquid, pushing the liquid to continue upward movement; at the same time, the inclined blades 2 can also provide a lateral force to the liquid , So that the liquid can move laterally, so that the liquid can be spread all over the inner wall of the tapered tube 111;
驱动机构带动锥形管111持续旋转，在康达效应的共同作用下，液体从锥形管111的小端向大端爬升，最终达到锥形管111内壁的顶部；The driving mechanism drives the tapered tube 111 to continuously rotate. Under the combined action of the Conda effect, the liquid climbs from the small end to the large end of the tapered tube 111, and finally reaches the top of the inner wall of the tapered tube 111;
锥形管111内腔的液体在向上爬升的过程中流经管壁的通孔，液体在离心力作用下穿过通孔沿径向向外甩出并撞击到外筒61的内壁，由于锥形管111的任意高度处均分布有通孔，因此锥形管111的任意高度处均有水甩出，从而在锥形管111与外筒61之间的气液混合空间中布满飞溅的水滴和水线；The liquid in the inner cavity of the conical tube 111 flows through the through hole in the pipe wall during the upward climb. The liquid passes through the through hole under the action of centrifugal force and is thrown out radially outward and hits the inner wall of the outer cylinder 61. Through holes are distributed at any height of the tapered tube 111, so water is thrown out at any height of the tapered tube 111, so that the gas-liquid mixing space between the tapered tube 111 and the outer cylinder 61 is full of splashing water droplets and Waterline
与此同时，由于风扇7与锥形管1同步旋转，风扇7所形成的气流从外筒6与液面之间的间隙进入并由下向上穿过气液混合空间，从而在气液混合空间内实现气体与液体的充分接触和混合。At the same time, due to the synchronous rotation of the fan 7 and the tapered tube 1, the air flow formed by the fan 7 enters from the gap between the outer cylinder 6 and the liquid surface and passes through the gas-liquid mixing space from bottom to top, thereby in the gas-liquid mixing space Realize the full contact and mixing of gas and liquid inside.
锥形管1的管壁上所开设的通孔的面积和数量决定了液体所能到达的高度；控制通孔的面积和数量，使液体能够到达锥形管1的大端。The area and number of the through holes opened on the wall of the tapered tube 1 determine the height that the liquid can reach; the area and number of through holes are controlled so that the liquid can reach the large end of the tapered tube 1.

工业实用性Industrial applicability
本发明是基于大量实验的实用性研究，经实验证明，当锥形管的转速达600转/分钟时，就能够使液体沿锥形管的内壁向上流动，从而有效实现气液混合。显然，本发明的液体输送原理还利用了流体力学的伯努利原理和流体的康达效应，这是由于当锥形管持续旋转时，锥形管的内表面能够将液体持续带起形成连续流体，该连续流体具有流体动力并向上流动，从而实现液体由下向上的流动；另一方面，液体在锥形管和外筒的气液混合空间中连续飞溅也不断扰动着气体的流动，使气体和液体的接触更充分。The invention is based on practical research based on a large number of experiments. Experiments have proved that when the rotation speed of the conical tube reaches 600 rpm, the liquid can flow upward along the inner wall of the conical tube, thereby effectively realizing gas-liquid mixing. Obviously, the liquid transportation principle of the present invention also uses the Bernoulli principle of fluid mechanics and the Conda effect of fluids. This is because when the tapered tube continues to rotate, the inner surface of the tapered tube can continue to carry the liquid to form a continuous Fluid, the continuous fluid has fluid dynamics and flows upwards, so as to realize the liquid flow from bottom to top; on the other hand, the continuous splashing of the liquid in the gas-liquid mixing space of the conical tube and the outer cylinder also continuously disturbs the flow of gas, so that The contact of gas and liquid is more complete.
本发明的气液混合效果受锥形管的高度、锥形管的转速、开孔数量、孔的形状、孔的大小、叶片的形状影响，可根据实际需要进行选择和匹配。本发明的气液混合效果决定了加湿效率或空气处理效率。The gas-liquid mixing effect of the present invention is affected by the height of the tapered tube, the rotation speed of the tapered tube, the number of openings, the shape of the hole, the size of the hole, and the shape of the blade, and can be selected and matched according to actual needs. The gas-liquid mixing effect of the present invention determines the humidification efficiency or air treatment efficiency.
另外，由于锥形管为上大下小的结构，锥形管上部的旋转线速度大于锥形管下部的旋转线速度，因此本发明的输送距离越大，流速越高。In addition, since the tapered tube has a structure with a large upper part and a small lower part, the rotational linear velocity of the upper part of the tapered tube is greater than the rotational linear speed of the lower part of the tapered tube. Therefore, the greater the conveying distance of the present invention, the higher the flow rate.
