Abstract

PURPOSE:To make it possible to generate thrust with a high degree of efficiency, by jetting high pressure liquid and gas from respective jet ports in parallel with each other, and by mixing the liquid gas after the liquid and the gas surrounding the liquid run through a guide cylinder and then they are mixed with materials to be conveyed, while their laminar stream is maintained, so that the materials are conveyed. CONSTITUTION:High pressure liquid and gas are jetted from jet ports 5, 6 in parallel with each other, and run through a guide cylinder 4, and the drive fluid consisting of the high pressure liquid and gas which run is jetted toward a conveyor pipe 2 in the discharge direction thereof through openings formed on one side section of the connecting part between the transfer pipe 2 and a suction pipe 1. At this time, negative pressure created by the running drive fluid sucks up materials to be conveyed, through the suction pipe 1, and the materials are mixed with the drive fluid and are conveyed in the transfer pipe 2. In this case, since the liquid is surrounded by the gas, the liquid merges and mixes smoothly with the materials with less frictional resistance given by the transfer pipe 2. Further, due to the synergism with negative pressure created by the running high pressure gas within the transfer pipe 2, an extremely large negative pressure is produced, thereby it is possible to generate thrust with an extremely high degree of efficiency.

傷を受けるという欠点がある。The method of generating thrust from this ridge is known to all souls, and can be roughly divided into two methods. One method is to connect the suction pipe and the conveyance pipe in a straight line, and the other is to connect the two pipes in a bent manner. In the former case, the injection port is located at the rear of the suction pipe (
Insert the jet nozzle [7, its jet L] into the direction of the flow of the conveyed object (Q) at the downstream position
Direct the high pressure fluid towards this! This is a method of generating thrust by applying negative pressure (suction) to the transported object by applying the f+f rule. However, in this method, since the jet nozzle is located at the above-mentioned position, it becomes a so-called "nod" against the flow of the sucked material, which obstructs the flow and creates a large frictional resistance - therefore, the particle size of the transported material is In addition to being naturally limited, excessive wetting of the jet water pressure by i% has the disadvantage that cavitation and vortex flow occur, and the nozzle itself is damaged by erosion and impact.

換することか不可能となるデメリットも生じる。In order to eliminate this drawback, in the latter method, the suction pipe and the conveying pipe are connected in a bent manner, and one injection port is located behind the delivery pipe on the hand MU side of the suction volume. By mounting a jet nozzle on the bent connection part, the formation of a nozzle is avoided.In this case, the suction force of the driving liquid is used to suck air from the opening that communicates with the atmosphere, and a single liquid flow. It has been proposed to prevent the generation of gear vibration and to transmit the driving force to the conveyed object in a diagonal manner by surrounding the conveyed object with air. Since the negative pressure is reduced by 1, the driving energy of the liquid in the liquid is doubled between the two layers, resulting in a disadvantage that it is impossible to convert 100% into the by-product to be transported.

In addition, the objects to be conveyed after mixing consume extra driving force corresponding to the increase in the number of whistles, and a vicious cycle occurs in which the suction force is reduced accordingly.

ることになる。The operation of the thrust generation method having such a configuration will be explained. One end of the suction amount -1 is immersed in the conveyed material such as water, sludge, slurry, etc. (tl13, not shown). Suppression liquid and high pressure gas are injected into the injection port 5. It is injected parallel to f'h and stops in the guide direction 4. And ノ general delivery piece '2 and suction' 1 tube 1
This protruding driving fluid consisting of the suppressing liquid and pressurizing gas is ejected from the opening provided on one side of the connection part with the IIGM fluid in the discharge direction of the transport shaft 2. The object to be conveyed is sucked away from the suction pipe 1 by the stopper), mixed with the rear driving liquid, and sent through the conveyor (a). In this case, when the driving liquid is mixed with the conveyed object, since the driving liquid is surrounded by 1"dj pressure gas, it is received from the conveying pipe 2 (). The wall of the suppressing gas first absorbs the resistance when the object joins the driving liquid, so it merges and kneads more smoothly.Also, the negative pressure caused by the stoppage of the high-pressure gas in the conveying pipe Due to the synergistic effect with (suction force), the jet flow of the monobacterial liquid increases the initial velocity at the time of jetting, and suddenly reaches the conveyance zone and has an extremely large amount inside the jet flow layer. Negative pressure (suction) will be generated.

As described above, the initial velocity of the jet flow of the pressurized liquid can be appropriately set so as to be maintained at a slightly increased speed.

Integrated with J4, fixed distance with dedicated high pressure gas pipe 8: jjlL
The difference is that the side effect of parallel "m" is given to the high-pressure gas.Furthermore, the influence of the driving force on the conveyed object changes from 111] if the direction in which the high-pressure liquid flows into the jet nozzle differs by 90 degrees. do not have.

防止することもこれによって行える。In the embodiment shown in FIG. 3, the direction in which the pressure liquid flows into the jet nozzle is different by 11 points compared to the embodiment shown in FIG.
The difference is that another high-pressure gas is added by the injection pipe 13 for pressurized gas, and in this case, this high-pressure gas is used to alleviate competitive resistance (kinetic viscosity) in the case of movement and outflow due to the viscosity of the liquid itself. It acts as a lubricant for liquid movement by injecting a small amount of gas that does not damage the tonality (metallicity) of the pressurized liquid into the central axis of the most effective liquid outflow. Therefore, according to the method of this third embodiment, more effective suction force and thrust can be applied to the transported object. Also very good pressurization (9/cA at 600-700)
This also prevents the driving liquid from freezing when the liquid (water in this case) is used.

得ることができる。For example, when the device is used as a propulsion device for a ship's hull, etc., when the suction pipe is submerged in water, the water that is sucked up as an object to be conveyed stops flowing inside the conveyance pipe together with the above-mentioned suppressed gas-liquid two-phase flow. The above-mentioned ship body etc. obtains propulsive force due to the reaction of the suction pipe, and when the suction pipe is above water, propulsive force is also obtained due to the reaction caused by the collision between the intake air and the above-mentioned two-phase air-liquid flow. can be obtained.

よい推力発生方法として作用する。As detailed above, in the single-thrust generation method, high-pressure liquid and suppressed gas are injected in parallel from their respective injection ports, flow as a parallel two-layer flow or quasi-three-layered flow, and the liquid flow is surrounded by the suppressed gas. After stopping inside the guide part in the shape of S, it mixes with the sucked up conveyed object, but even after mixing, the laminar flow shape is maintained while mixing and conveying the conveyed object. - Most of the kinetic energy it possesses is efficiently given to the object as suction and transport force, so it acts as an extremely efficient method of generating thrust.

もなる悪循環の削減に効果的に働らく。Moreover, there is nothing inside the conveyance pipe that would obstruct the conveyed object, and any object up to the inner diameter of the suction tube can be suction conveyed. Furthermore, in this thrust generation method, in addition to the high-pressure liquid, high-pressure gas is used as the driving fluid in parallel flow, so the driving energy of the high-pressure liquid can be absorbed and 100% used for conveyance, and at the same time, it is possible to reduce the local pressure. It is also possible to prevent cavitation (hollowing phenomenon) caused by The synergistic effect with the suppressing gas effectively works to reduce the vicious cycle in which the driving liquid becomes a transported object.
