KR-20260066036-A - orbicular capillary tube

Abstract

The present invention relates to a device for raising water by mounting a plurality of pipes at small intervals on a center axis (1), and more specifically, to a device for raising water by causing capillary action to occur at a gap of 0.1 mm. The circular capillary device according to the present invention is formed in a circular shape, and a pipe (small) (2) is installed on the outer side of the center axis (1) at a distance of 0.1 mm, a pipe (medium) (3) at a distance of 0.1 mm, and a pipe (large) (4) at a distance of 0.1 mm, thereby producing a capillary effect, and subsequently, a material with strong absorbency, such as a thread (5) of 0.1 mm or less, is used on the upper side. Therefore, when the capillary tube is installed in water, the ball of the lower check valve (6) is lifted by buoyancy (B) and water enters, then rises along the wall of the capillary tube due to the capillary action and continues to the thread (5), and the water stops when the force equilibrium is reached. Afterwards, as the water inside the capillary tube reaches force equilibrium, the ball of the lower check valve (6) goes down and blocks the inflow of water.

Description

orbicular capillary tube The present invention relates to the capillary phenomenon in which water rises from a lower point to a higher point in a capillary tube. More specifically, it relates to a method for solving the problem where, inside the capillary tube, water rises along the inner wall at a constant angle due to surface tension to maintain a constant height, but the amount of water is extremely small. Generally, the capillary phenomenon refers to the fact that when a capillary tube is placed upright in water, the water rises above the surface. The reason the water rises is that surface tension is generated inside the capillary, causing it to travel up the inner walls. To maximize the height of the water using surface tension, the inner diameter of the capillary must be as small as possible; for this reason, most capillaries utilize a circular water column shape. [Representative drawing] is an assembly drawing in which pipes are assembled on the center axis with a spacing of 0.1 mm and a check valve for backflow prevention is installed at the lower water inlet. [Fig. 1] is a cross-sectional view showing the state in which water rises in a column due to capillary action, with the diameter of the capillary and the height of the rising water represented by an equation. [Fig. 2] is a cross-sectional view in which a pipe is fitted onto the center axis to create a fine gap, causing the water to rise, and the inner and outer diameters and the water height are represented by equations. A preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. First, since the present invention utilizes the capillary phenomenon, the height must be calculated according to the diameter of the capillary as shown in [Fig. 1]. The basic calculation method is that the upward force F is the surface tension acting on the inner circumference in the direction of cos 20 degrees, and the downward force W is the specific gravity of water acting downwards due to gravitational acceleration in proportion to the base area and height. The goal is to determine the height H when the force F and the force W are equal. Therefore, in [Fig. 1], the height at a diameter of 0.1 mm is 279 mm. However, since the amount of rising water in [Fig. 1] is not large, [Fig. 2] was devised as a subsequent method. [Fig. 2] shows a pipe fitted onto a center axis with a gap of 0.1 mm. In this case, the method for calculating the height of the rising water is similar to the method in [Fig. 1]. First, the upward force F is the sum of the two forces: surface tension acting on the inner diameter of the pipe at cos 20 degrees and surface tension acting on the outer diameter of the center axis at cos 20 degrees. The downward force W is equal to the volume of water when the volume of the center axis outer diameter is subtracted from the volume of the pipe inner diameter. Thus, to calculate the height using the gap spacing with the formula in [Fig. 2], one simply needs to set the actual dimensions. Assuming the pipe inner diameter is 40.2 mm and the center axis outer diameter is 40 mm, and setting the gap spacing to 0.1 mm, the height is calculated to be 149 mm. This time, we will calculate the height in the [representative diagram], which consists of several capillaries, using the calculation method in [Fig. 2]. The rising force F (the rising force inside the capillary) is The falling force W (load of water inside the capillary) is The falling force (the load of water in the portion excluding the volume of the ball inside the backflow prevention check valve (6)) is The falling force (load of the ball inside the backflow prevention check valve (6)) is To summarize, 0.01721=0.123457H + 0.0021217 + 0.000804 Therefore, H = 0.1157 m = 115 mm The water height in [Representative Diameter] is 115 mm. In addition, it can be seen that a significantly larger amount of water can be lifted compared to a single capillary tube. Now, the above information can be summarized as follows. When a circular capillary tube is installed in water, the check valve (6) opens due to buoyancy, and then water rises due to the capillary action. When the forces are in equilibrium, the water level is maintained at a constant 115 mm. At this time, the ball of the check valve (6) below descends due to gravity and closes, blocking the inflow of water from the bottom of the capillary tube. Also, as a thread (5) is inserted in the [representative diagram], water moves along the thread and stops when the forces are in equilibrium. At this time, the ball of the check valve (6) below descends and blocks the water inflow. Additionally, solar energy evaporation is constantly occurring in the thread. <Refer to terms below> F: Force climbing the inner wall of the capillary (Surface tension * COS 20 * Inner circumference) W: Load of water inside the capillary (water volume * density * gravitational acceleration) fs: force climbing the thread ( surface te
