Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a liquid trickle ejector with a novel structure for ejecting a predetermined liquid in a suitable liquid or gas as a very thin jet stream, which is suitable for use in dyeing baths. A device for evenly adding auxiliary agents to water, a device for evenly adding chemicals to tap water,
Evenly distributed discharge device for cleaning liquid in gas cleaning equipment,
This invention relates to a liquid trickle sprayer that can be conveniently used as a water sprayer for uniformly distributing cultivation water to plants.

Prior Art Conventional devices for making liquid into a trickle stream include devices that eject liquid from a small diameter nozzle such as the end of a small inner diameter tube, and devices that eject liquid from a large number of pores drilled in the disk surface or peripheral wall of the tube. There are devices that eject liquid, but all of them have nozzles or holes with very small diameters that are difficult to mechanically create, making it difficult to create a very fine liquid flow, or those nozzles or holes may become clogged with foreign matter and must be cleaned. This requires troublesome work such as inserting a thin wire or the like into the nozzle or hole to clean it when necessary.

Problems to be Solved by the Invention In consideration of the above-mentioned circumstances, the present invention is capable of freely generating a very fine liquid flow, and is capable of decomposing even when foreign matter is clogged and the jetting of the liquid flow is stagnant. The object is to obtain a liquid trickle ejector that can be easily cleaned.

Means and Effects for Solving the Problems The present invention provides a material having a continuous flat cross-section and having an appropriate number of thin grooves 2 on the front surface and/or back surface 1 that communicate between the inner peripheral edge and the outer peripheral edge. By pressing the coil spring-like multiple annular body 3 made using the coil spring from both ends, the same-phase parts of each pitch can be made liquid-tight with each other except for the narrow groove 2 part, and can be attached and detached freely. While forming the ring laminate 4 to be polymerized and crimped,
While supplying a predetermined liquid under pressure to the inner peripheral edge or outer peripheral edge of the ring laminate, it is ejected to the outer peripheral edge or inner peripheral edge of the ring laminate through the two narrow grooves, respectively. This is a liquid trickle ejector characterized by:

In the liquid trickle ejector having such a structure, the liquid to be supplied does not pass from the inner peripheral edge or the outer peripheral edge of each pitch portion of the multiple annular body 3 to the outside of the other edge except through the narrow groove 2. There is no way to pass through to the periphery or inner periphery, and the thin grooves 2 are provided on the front and/or back surfaces of each pitch of the multiple annular body, and it is difficult to use a method such as scribing with a scribing needle. As it is possible to freely make fine grooves by
It becomes easy to eject the liquid to be supplied as a trickle of a desired diameter. Further, a thin groove 2 provided on the front surface and/or back surface 1 of each pitch portion of the multiple annular body 3
Since the number and direction of the liquid droplets can be freely selected, it is possible to freely select and change the number, density, and direction of the liquid trickles ejected from the ejector. Furthermore, if the thin groove 2 is clogged with foreign matter and the ejection of the liquid stream becomes poor, the annular laminate 4
Clogging caused by foreign matter can be easily cleared by a method such as releasing the crimped state between each pitch part of the multiple annular body 3 and rubbing the front surface and/or back surface 1 of each pitch part with a brush. Therefore, it becomes a squirt device that can be used even for liquids containing fine particles.
It also becomes an economical squirt device that can be used semi-permanently.

And this liquid trickle ejector has its annular laminate 4
Since it is made up of continuous coil spring-like multiple annular bodies 3, the pitch parts do not separate and dissipate when the crimped state between the pitch parts is released during disassembly and cleaning. This makes it easy to handle, and when reassembling, there is no need to align the phases of the pitch parts or distinguish between the front and back sides, making reassembly easier.

In addition, this liquid trickle ejector can be constructed from metal or synthetic resin, which has high mechanical strength and chemical resistance due to its structure, so it can be used as a ejector without worrying about breakage or corrosion. It also becomes easier to do so.

Example 1 As shown in Fig. 2, a coil spring-like multiple annular body 3 is made using a material with a continuous flat plate-like cross section, and when it is pressed from both ends, the same phase part at each pitch is In addition to being able to be superimposed and pressed together in a liquid-tight manner, a thin groove 2 is provided on the surface 1 of each pitch to form an annular laminate 4. In a liquid trickle ejector using such an annular laminate 4, when the pressure from both ends of the annular laminate 4 is stopped, the spacing between each pitch part automatically becomes larger as shown by the chain line, so the fine groove 2 In addition to making cleaning operations easier, each pitch section will not be separated or scattered during the cleaning process, so you will not have to worry about aligning the phases of each pitch section or distinguishing between the front and back sides when reassembling. If this can be omitted, handling becomes extremely easy. As shown in Figure 1, this liquid trickle ejector has an air-blowing stirrer 9 on the bottom that can gently stir the dyeing liquid 8, since strong stirring may damage the surface structure of the silk thread. A suitably installed silk yarn dyeing machine 10 is similarly installed on the bottom, and dyeing aid liquid such as acetic acid is injected into the annular laminate 4 of the spout through the liquid conduit 7 as required for the dyeing operation. By press-fitting the dyeing aid into the periphery and spouting it out as a trickle from the outer periphery, the entire dyeing bath 8 can be created using only the stirring action of the air-blown stirrer 9, which is not a very powerful stirrer. It is now possible to mix the silk thread evenly and simultaneously, and it is now possible to easily achieve the required level dyeing without damaging the surface structure of the silk thread.
It is also extremely useful as a device for evenly adding chemical solutions into water treatment tanks for tap water, a device for uniformly watering cultivated plants in farms, a device for evenly distributing cleaning water into the exhaust air in exhaust cleaning equipment in factories, etc. This is the result. Note that reference numbers 6 and 6' in FIG. 1 press the ring laminate 4 from both ends to make the same phase parts of each pitch so that they are mutually liquid-tight except for the two narrow grooves. In particular, the crimping tool 6' has a built-in hole through which the liquid from the liquid conduit 7 can be forced into the inner peripheral edge of the annular laminate 4. It has become a thing. In addition, the reference numeral 5 in FIG. 2 indicates the crimping tools 6, 6'.
2 shows a core material that may be inserted into the inner peripheral edge of the annular laminate 4 as part of the annular laminate 4.

Embodiment 2 In the example shown in FIG. 3, the aforementioned coil spring-like multiple annular body 3 is attached to an exterior tube 19 having an inner diameter that is approximately the same as its outer diameter.
While being accommodated in the annular laminate 4,
By introducing the liquid between the inner circumferential wall of the outer tube 19 and the outer circumferential edge of the annular laminate, it is possible to supply the liquid to the outer circumferential edge of the annular laminate under pressure, and the liquid is supplied to the outer circumferential edge of the annular laminate through the narrow groove 2. The liquid is ejected from the inner peripheral edge of the ring laminate. Notches 20 are provided at four locations on the outer periphery of the multiple annular body 3 that are in phase with each other for each pitch, and the cutouts 20 are provided as passages for the liquid to be introduced. After providing the thin grooves 2, the multiple annular body 3 is attached to the outer tube 19.
Inside, it is pressed from both ends to form an annular laminate 4.

If the liquid trickle ejector that ejects liquid toward the hollow part of the annular laminate 4 has a structure that allows air to pass through the hollow part, it can be used as a high-efficiency gas scrubber or absorber. , or a humidifier.

Effects of the Invention As is clear from the above description, the liquid trickle ejector of the present invention has the following effects.

(a) Since the thin grooves 2 provided on the surface 1 of each pitch portion of the multiple annular body 3 can be made as thin as desired, a liquid stream of a desired diameter can be ejected efficiently. .

(b) Since the crimping between the pitches of the multiple annular body is removable, it is easy to clean the narrow grooves on both sides of each pitch, which is the crimping surface, and it can be used permanently. In addition to serving as a jetter for liquid trickles, the ring laminate is made up of continuous coil spring-like multiple ring bodies, so there is no risk that each pitch will dissipate when the mutual pressure between the pitches is released. This makes it easy to re-crimp them together and assemble them into an annular laminate, resulting in a liquid trickle ejector that is extremely easy to overhaul.

(c) Since the structural material can be freely made of stainless steel or synthetic resin, it is possible to create an ejector with high mechanical strength and strong chemical resistance.

(d) Devices that can add chemical solutions and auxiliary solutions to other liquids in a tank while uniformly dispersing them from the beginning, gas scrubbers, agricultural water sprinklers, etc., as well as devices and instruments that can be used immediately. It is possible to improve the performance of the system to a higher level of efficiency than ever before.
