Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container for supplying a fixed amount of various water treatment chemicals at a constant rate.

Traditionally, water treatment agents for wastewater, wastewater, circulating water, and other water systems are added to the water to be treated, and in order to achieve the treatment purpose, for example, a certain amount of the treatment agent is applied at a certain location at a predetermined time. It was added continuously or intermittently over time to ensure thorough mixing or dissolution.

Water to be treated includes, for example, circulating water from swimming pools, drinking water introduced from rivers, reused water, car washing water, building wastewater, and other water that needs to be treated in large quantities. A treatment agent is mixed with the water to be treated to generate a precipitate, and the precipitate is removed by filtration to obtain clean water.

In addition, disinfectants, algaecides, nutrient enrichers, and other necessary chemicals are added to irrigation water, fish ponds, zoological and botanical garden water, and other water sources. Note that coloring agents, neutralizing agents, disinfectants, biocides, and other necessary chemicals may be used alone or in combination with the above-mentioned chemicals, and there are some differences in the amount of treatment.

In any of these cases, it is important to add an appropriate amount of a predetermined treatment agent into the water to be treated at a predetermined rate to ensure uniform dispersion. Many proposals have been made as methods or devices for this purpose, but
Many use extremely sophisticated and complex mechanisms and are equipped with large fixed or portable measuring units. No one has been found that is small in size, suitable for a mechanism and method for simply adding a treatment agent, and that can be applied both when the amount of treated water is small and when it is considerably large.

Preferably, the system should be able to be reliably added to the normal routine water supply or circulation flow path in a consistent manner, without requiring the application of faulty parts, drives or electrical circuits. . In routine processing, the conditions are almost constant, so workability and efficiency can be reliably predicted.

Furthermore, the purposes of water treatment are diverse, as described above. Therefore, it is preferable to use one that can be applied to multiple processing purposes. However, not enough was provided yet.

As is clear from Japanese Patent Application Laid-Open No. 52-4638, the present inventor has broken through the above-mentioned current situation and developed a container with an appropriate shape that can supply a fixed amount of processing chemicals at a fixed time (hereinafter referred to as "container"). The water treatment agent charged in the container is placed in the water system, and the water treatment agent powder or its solution stored inside the container is continuously poured into the water to be treated through the small hole provided in the container. We have previously proposed a simple and rational water treatment chemical supply container that is suitable for dispensing or discharging water treatment chemicals.

However, in the above-mentioned Japanese Patent Application Laid-open No. 52-4638, it is possible to always reliably maintain the attitude of the container in the water to be treated at a substantially constant level, and to uniformly supply only a predetermined amount of the chemical, and the manufacturing method thereof is easy. However, it was not possible to provide a water treatment chemical supply container.

The present invention further improves the water treatment chemical supply container disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 52-4638, and makes it possible to reliably control the attitude of the container in a water treatment system and to facilitate its manufacture. The purpose of the present invention is to provide a container for easily supplying water treatment chemicals.

Next, some embodiments of the present invention will be illustrated and explained. 1 and 2 are system explanatory diagrams showing two types of application examples of the water treatment chemical container 1 of the present invention in a rather large water circulation system, and FIG. 3 is a system explanatory diagram showing another example of application in a small water system. 4A and 4B are perspective views, and FIGS. 5A and 4B are side and top sectional views showing an example of the container of the present invention, which can be applied to the systems of FIGS. 1 to 3, applied to another small water system. Fig. 5B is a perspective view and a side view showing a partially enlarged cross section of an example applied to a small-sized water sprinkler, Fig. 6A is a side sectional view showing the relative position for attaching a weight to the container of the present invention; FIGS. 6B and 6C are partially enlarged side sectional views of two embodiments with a weight attached, and FIGS. 7A and 8A are two other embodiments before molding with a weight and a cap attached. FIGS. 7B and 8B are partially enlarged side sectional views of the example after installation in the case of FIGS. 7A and 8A.

In the water circulation system shown in FIG. 1, the container 1 of the present invention contains an appropriate chemical, and the water to be treated W in the water tank 2 is supplied through piping 14, a simple filtration tank 4, a pump 3, and a cooler (or heater) 5. It passes in the direction of the arrow, passes through the piping 15 and the water tank 6, flows through the piping 11, and is circulated to the water tank 2 described above.

For example, when fish are being cultivated in the water to be treated W in the aquarium 2, a first water purifier solution that does not generate sediment is built into the container 1 in the aquarium 2, and a simple filter tank 4 in the canal system is installed. A second water purifier solution that instantaneously forms precipitated flocs on the filtration layer is contained in the inner container 1. A container 1 containing an algaecide solution for fish cultivation can be used in the water tank 6 of the supplied water from which precipitated aggregates have been removed and maintained at a predetermined temperature.

In the water circulation system shown in FIG. 2, water W from the bottom of the water tank 2 and water falling from the overflow reservoir 12 are guided to a first treatment water tank 16, and a container containing an appropriate first water treatment agent is introduced. 1 performs the first process. This water is guided by a pump 13 to a second treatment water tank 8 through a pipe 20, a filter water tank 4, and a pipe 14, and is subjected to a second treatment in a container 1 containing a second water treatment agent. This water is returned to the water tank 6 via the pipe 18, and is supplied to the water tank 2 through the pipe 11 by the pump 3.

In addition, the water falling from the overflow reservoir 12 is not passed through the tank 16, but is subjected to a third treatment in the third treated water tank 7 via the water pipe 9, and then passed through the second treated water tank 8 to the water supply tank 6. Return to. The water in the filtered water tank 4 or the water tank 8 can also be treated using the container 1 containing an appropriate chemical.

The container 1 of the present invention used in the water circulation system of FIGS. 1 and 2 is a normally hollow plastic sphere equipped with a weight and having a suitably shaped flange attached to the side surface of its outer shell. It comprises at least one, at most ten, and usually from one to four small holes of suitably small area. If necessary, the spherical shape can be changed into other polygonal shapes.

The medicine in the container 1 is contained as a concentrated solution, powder, or a mixture thereof. The small holes provided in the outer shell are not perforated, but the perforated locations are marked and closed before use to ensure sufficient durability during packing, transportation, and storage.
The drug is stored in the container 1, the storage hole is closed, a weight is secured with a plastic cap, and then the shell and the cap are completely fused and sealed.

The weight is used to help maintain the posture and position of the container underwater, and can be of various shapes and made of various materials. Usually, lead balls for shotguns or crushed into discs are used because they are easily available and convenient.

However, the material and shape are not limited to these. Whatever you need,
Can be used as a weight. Examples include balls of pachinko, glass balls of ramune players, balls or rollers of bearings, sintered bodies of ferrite magnets, ceramic disks, cut pieces of metal wires or metal rods, and the like. This is shown in FIG. 5B, which will be explained later.

Suitable plastic materials for the shell and cap include vinyl chloride, lexan, polycarbonate, polyethylene, polypropylene, polystyrene, polyurethane, other polymeric compounds and blow molding resins.

The chemicals in container 1 include neutralizing agents, flocculants, bactericides, clarifying agents, foaming agents, antifoaming agents, algaecides, acaricides (for fish), herbicides, growth promoters, and fertilizers. , ionic agents, demetalized ionic agents, disinfectants, and other agents are used.

From these chemicals, an appropriate amount is arbitrarily selected and used based on theoretical and empirical values, depending on the purpose of water treatment. Further, depending on the use, the shape of the container, the weight of the weight, the number and diameter of elution holes, the shape of the flange, etc. are arbitrarily selected and used.

The container 1 has a hole that penetrates the outer shell from inside to outside.
Puncture with a cutter or needle of a specified cross-sectional shape. The weight of the weight of the drug-containing container is selected so that it can maintain its posture and position and float on the surface or bottom of the water to be treated. Alternatively, the drug may be initially placed in a deep part and not remain there, but float to the top below the water surface as the drug is eluted and replaced with water. It can also be configured to stay in a certain location.

During a certain period of time when the container 1 floats in the water, the drug in the container 1 is eluted at an elution rate suitable for the water to be treated. The drug in the container 1 becomes a saturated solution in still water, elutes and diffuses into the water to be treated outside through the small holes in the outer shell, and is gradually distributed in the tank. In the container 1, as the drug elutes, if the drug is a solution, it is diluted to maintain an equilibrium, and if the drug is a powder and a solution, the powder dissolves so as to achieve saturated dissolution, and the powder gradually dissolves. Concentration in treated water increases.

In running water, in addition to the above-mentioned case in still water, the flange attached to a predetermined area around the center of the outer shell receives the water flow on one side, and on the other hand, is restored like a daruma by a weight. The drug tries to move, floats around, and promotes drug elution from the small pores.

The small holes provided in the outer shell can be dispersed around the entire outer periphery if necessary, but they are usually provided at a position suitable for the purpose of use, such as at the diagonal lower part. Further, in order to keep the elution rate of the drug constant, the shape of the holes, such as a circle, and the number of holes are determined.

In other words, if the chemical solution in the container 1 is heavier than water, a small hole is provided at the top of the container 1 to prevent the chemical from flowing out too much from the container 1 when the water to be treated is still. If the drug solution in the container 1 is lighter than water, a small hole is provided at the bottom of the container 1.

In this way, if the water to be treated is stationary,
Gravity does not affect the outflow of the drug, and the drug flows out only by diffusion, but the outflow due to this diffusion is extremely small. For this purpose, the attitude of the container 1 is maintained by the weight as described above.

Furthermore, in order to uniformly supply the drug into the water to be treated, if the drug solution in the container 1 is heavier than water, the container 1 is placed on the water surface, and conversely, if the drug solution in the container 1 is lighter than the water. In this case, it is necessary to position the container 1 at the bottom of the water. For this purpose, the position of the container 1 is maintained by the weight as described above.

Since the container of the present invention can be arbitrarily and extremely easily selected in its shape and location, it can be applied to water treatment systems ranging from relatively small to large water treatment systems.

In addition, a predetermined amount of water treatment chemicals of a predetermined quality is stored in the container 1 in advance, and the container is completely and firmly sealed.
A predetermined number of small holes are drilled at predetermined locations and placed in water immediately before use, so there is no risk of chemical leakage and is completely safe before use, and there is no risk of deterioration of the chemical. There is no need to worry, and the manageability and safety guarantee are extremely high.

Furthermore, when necessary, the state of dissolution of the drug can be easily determined by coloring the drug to make it easier to recognize the dissolution, or by making the shell of the container made of transparent plastic.

Furthermore, litmus, phenolphthalein, and other indicators may be added to the container of the present invention together with or separately from the treatment agent, for example, when placing detergents in the container, or when treating with neutralizing agents, oxidizing agents, or reducing agents. It can be stored to measure neutrality or alkalinity. In this way, it is simple, easy and extremely convenient.

Next, an example will be described in which the container 1 of the present invention is applied to a small, small-capacity water system. Third
The figure is a perspective view of one embodiment applied as a sprinkler. Tap water W is made to flow through the hose 21 in the direction of the arrow and introduced into the mixing chamber 22 through the fixed port 25 of the hose 21.

The flow rate of water introduced from the water supply port 25 decreases within the mixing chamber 22. As shown in FIG. 4A as a side cross section and as shown in FIG. 4B as a plane cross section of the AA cross section, the powdered drug 43 filled in the container 1 is
It dissolves in the solution to form a solution 43A. The container 1 is operated by a weight 49 fixed to the outer shell 45.
It oscillates as the water supply W flows past, while trying to maintain a constant posture with the body facing down. For this reason, the outer shell 45
From the small holes 41, the drug solution 43A oozes into the water W and diffuses. A screw lid 29 is screwed together as a canopy of the mixing chamber 22 to make the inside of the mixing chamber 22 airtight.

A bactericide, a disinfectant, a soil conditioner, a fertilizer, or the like is used as the above-mentioned agent, and the agent is dissolved in water and mixed and diffused, and then the hose 24 attached to the water supply port 26 is used.
Through the sprinkler 23, it is sprayed onto trees, agricultural and forestry crops, lawns, etc. Although the example shown in FIG. 4A does not include a flange, the dissolution rate will be faster if the flange is attached.

FIGS. 5A and 5B show an embodiment in which the present invention is applied to a type of water bottle or water difference.

FIG. 5A is a partially enlarged perspective cross-sectional view. The shell 45 of the container 1 for the drug solution 43A is made of plastic and is provided with a predetermined number of small holes 41. shell 4
The cap 48 fused to the lower part of the shell 5 and the molded recess 47 formed in a predetermined part of the shell surround and fix the lead ball 49, and when the container 1 is inserted into the water to be treated, the lead ball 49 closes the fixed part. Allow it to sink downward. When it is necessary to sink the container 1 near the bottom 30 of the bathtub, a lead ball 49 of an appropriate weight is attached, and the inner cavity 44 is filled with drug powder or concentrated solution.

A specially shaped flange 46 is installed at a predetermined location approximately at the center of the spherical outer circumference of an outer shell 45 of a predetermined thickness with an appropriate thickness and length, usually forming a symmetrical pair with respect to the center of the sphere, so that the container 1 is submerged underwater. It has a shape that makes it easy to swing and float.

In addition, although not shown, the outer shell 45 may be shaped like a rugby ball and may be provided with a flange at a position forming a predetermined angle with respect to the longest center line or the shortest center line to facilitate rocking. In addition to the regular sphere, a polyhedron or a half thereof can also be used, but for convenience of explanation, the shape shown in the drawing will be described.

A recess 47 and a small hole 41 are formed in advance in the spherical shell 45, and after filling the drug through the hole 42 (FIG. 7A), a lead ball 49 that closes the hole 42 is inserted into the cap 4.
8 and press it to fix it to the shell 45. Hole 42
is a cap 4 using ultrasonic waves as shown in Fig. 6A etc.
The seal is securely sealed by pressure welding in step 8. Use shapes that suit the conditions of use.

The drug solution (same as powder) 43 is charged through the drug charging hole 42 and the lead ball 4 is inserted into the drug charging hole 42.
When the container 1 with the cap 48 fixed in the recess 47 is sunk into the bottom part 50 of the container, the hole 41 is closed.
The water to be treated W and the drug solution 43A in the shell 45 are
The processing chemicals 43 are eluted and diffused. Move the handle 33 of the water bottle to feed water in the direction of the arrow from the outlet 27 to the flow path 32. The type and amount of the drug to be added are determined in advance. For example, this is the same as the case shown in FIG. 3 above.

The container 1 of this example is extremely small in size, with a diameter of 5 to 30 mm, a diameter of the small holes of 0.1 to 0.2 mm, and a number of small holes of 1 to 4. It is attached.

If one small hole with a diameter of 0.1 mm or less is attached to the shell 45, the elution of the drug will be extremely poor, and the diameter will be
In the case of one small hole of 0.125 mm or more, good elution was shown. In the case of six small holes with a diameter of 0.2 mm, the elution amount was large and was more than necessary. Usually, at least one small hole is provided in the lower part of the spherical container 1 with a diameter larger than 0.1 mm. These numbers are adjusted to suit the conditions of the application.
Select and attach arbitrarily.

The container 1 is manufactured by blow molding or the like. After this blow molding or the like, the bottom plate of the recess 47 may be removed using an ultrasonic oscillator or the like, and the removed portion may be used as the hole 42 for drug insertion, as shown in FIG. 8B.

Next, a method for fixing the weight body to the recess 47 of the half-finished shell 45 of the molded container 1 will be described with reference to FIGS. 6A to 8B. In these examples, a lead ball, which is a shotgun bullet, is used as an example of the weight, but the weight is not limited to a lead ball. For example, it may be made of metal, glass, ceramics, or other materials, and may have various shapes such as a sphere, a disk, a cone, or a polyhedron. for example,
There are pachinko balls, glass balls, ceramic balls, etc. For example, if ceramic disks containing permanent magnets are used, the number of magnetized ceramic disks stacked in two or more layers can be easily changed, so the weight of the weight can be easily changed.

As shown in FIG. 6A, the semi-finished plastic shell 45 of the container 1 of the present invention is placed on a suitable support 59 with the flange 46 with the molded recess 47 facing upward.
It will be distributed by. Ultrasonic oscillator horn 71
A processing tool 72 is provided at the end of the plastic cap 48, and the plastic cap 48 is pressed by the end surface 73 of the processing tool 72, and the cap 48 is fused by ultrasonic vibration (FIG. 6B etc.). Therefore, fixing the lead ball 49 and opening the hole 42
Since the closing and closing of the cap 48 are performed at the same time by fusing the cap 48, manufacturing is easy.

FIG. 6B shows plastic shell 45 from hole 42.
After pre-filling the inside with a drug, a lead sphere 49 is fitted into the recess 47, and a plastic cap 48 is fitted and sealed. FIG. 6C shows a case in which a lead disc 49 is used in place of the lead sphere 49, and a cap 48 is fitted and sealed in the same manner as in FIG. 6B.

In these cases, the cap 48 and the recess 47 may be fixed together with an adhesive. However, in many cases, chemicals used in water treatment must be treated harshly in order to have their proper chemical effects.

For example, selecting the appropriate drug, concentration, and amount for the application, obtaining, measuring, and loading it into containers, storing and transporting it in containers, maintaining quality, and taking precautions for safety and hygiene. , must be carefully considered.

To do this, a given supplier must store and manage the amount of medicine in a given container with optimal conditions in order to properly store the given drug in the given container and apply it correctly to the point of use. It is desirable that the product be supplied to the consumer in such a way that they can properly instruct its use, and that it be completely sealed.

For this purpose, it is preferable to seal the plastic container 1 by fusing the fitting and fixing portions of the plastic container 1 using ultrasonic vibrations, as shown in FIG. 6A.

In FIG. 7A, the end surface 73 (see FIG. 6A) of the processing element 72 attached to the end of the horn 71 is provided with numerous irregularities to form an end surface 74, and a recess 47 formed in the shell 45 is shown.
A lead ball 49 is inserted into the hole and a plastic cap 48 is fitted therein.

In FIG. 7B, the end surface 74 of the processing element 72 is pressed against the cap 48, and the part 40 shown in thick lines is fused by ultrasonic vibration, and the plastic cap 48 and the recess 47 are fixed by the fusion layer. It is integrated.

The embodiment shown in FIGS. 8A and 8B belongs to the embodiment set forth in claim 2, and in this embodiment, as shown in FIG. 8A, an upper opening type cap 48 is provided. The fitting portion 40 is fused and fixed as shown in FIG. 8B.

A small hole 41 (5th A) provided at a predetermined location of the shell 45
) is provided as a recess on the outer surface of the shell 45 when the shell 45 is molded. If possible, mark it with a color to make it easier to find, and immediately before use, puncture it with a drill or needle.

As described above, according to the present invention, the water treatment agent stored in the container 1 can be continuously eluted and dispersed into the water to be treated, and can be used in a sanitary manner. Moreover, it can be easily and quickly applied to both large and large volumes of water to be treated as well as small and small volumes of water, and the maintenance and management of the treatments is also easy.

In particular, according to the present invention, since the attitude of the container in the water to be treated can be reliably controlled, it is possible to control the vertical position of each through-hole for chemical outflow to be almost constant. In addition, the position of the container can be reliably controlled according to the weight of the weight, and therefore the medicine can be uniformly supplied in a predetermined amount. Further, since the fixation of the weight and the closing of the drug charging hole are performed at the same time by attaching the cap, manufacturing is easy.
