Abstract

PURPOSE:To improve the cleaning efficiency of a liquid by simplifying a cleaning system for the liquid to be cleaned. CONSTITUTION:Metal cotton 2 consisting of a magnetic body arranged around a bar magnet 1 magnetized in helical form generates a magnetic path around the magnetized bar magnet 1 in helical form in the same manner. A liquid to be cleaned W is passed through the magnetic field generated by the metal cotton in the longitudinal direction of the bar magnet 1. While the liquid to be cleaned W passes through the distance several times the length of the bar magnet 1, materials in the liquid to be cleaned W are magnetically attracted by the metal cotton 2 and their movement is prevented. Then, since a magnetic path is not generated in the form of a flat plate at a feeding part for the liquid to be cleaned W, the materials in the liquid to be cleaned W is not concentrated there, and not magnetically attracted by the metal cotton 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in polishing, grinding, electric discharge machining, hydraulic compression system, and other processes to remove unnecessary substances in liquids such as dirty water and dirty oil to obtain a liquid to be purified. The present invention relates to a liquid purification device for purifying liquid, and more particularly to a liquid purification device for removing unnecessary substances in liquid by purifying waste liquid. It is also possible to collect the silver that flows out during photographic development.

2. Description of the Related Art As a conventional technique relating to a purification device for purifying a liquid to be purified, there is a technique shown in FIG. 6, for example.

FIG. 6 is a block diagram showing the structure of a conventional liquid purifying apparatus in use.

In the figure, a waste liquid container 100 contains a liquid W to be purified, which flows from the outside (not shown). The pump 101 supplies the liquid W to be purified in the upper layer portion to the floating substance storage container 102. The pump 101 and the floating substance storage container 102 vacuum-remove substances mainly composed of relatively light components such as oil. It constitutes the upper layer purification system A.

The valve 103 is for adjusting the suction amount of the liquid W to be purified, and the pump 105 is for the filter accommodating and purifying means 1.
The liquid W to be purified is passed through 04 to purify the liquid W to be purified in the middle layer. Filter housing purification means 104
A polypropylene filter 104a is built in the filter cylinder 104b. The valve 103, the filter accommodating and purifying means 104, and the pump 105 constitute the intermediate layer purifying system B.

Further, the switching valve 106 switches between the discharging position C1 and the discharging position C2 when discharging the sludge or the like in the lower layer from the bottom of the waste liquid container 100. The lower layer liquid to be purified W that has passed through the switching valve 106 passes through the magnet filter means 107, where the bar magnet 107a built in the filter cylinder 107b magnetically removes the fine particles by the activated carbon 107c. Switching valve 106 and magnet filter means 1
After passing through 07, the liquid W to be purified in the lower layer is re-supplied to the upper portion of the waste liquid storage container 100 via the pump 108 and circulated. The switching valve 106, the magnet filter means 107, and the pump 108 form a lower layer purification system C that removes substances mainly composed of relatively heavy components such as sludge and abrasion powder.

The upper layer purification system A thus constructed purifies the floating component floating as the liquid W to be purified in the floating substance storage container 102, and collects it in the floating substance storage container 102. Further, the middle layer purification system B purifies a main liquid component as the liquid W to be purified in the waste liquid storage container 100, returns it to the waste liquid storage container 100 again, and repeats recirculation. Then, the lower layer purification system C purifies the precipitated component as the liquid W to be purified in the waste liquid storage container 100, returns it to the waste liquid storage container 100 again, and repeats recirculation.

In this way, the liquid W to be purified stored in the waste liquid container 100 is purified into three layers of the upper layer portion, the middle layer portion and the bottom portion. Purification systems are independently provided in the three layers of the liquid W to be purified, and the liquid W to be purified is circulated through these purification systems for purification.

[0009]

However, in the liquid purifying apparatus constructed as described above, the liquid W to be purified has three layers, that is, the upper layer portion, the middle layer portion and the lower layer portion, and is treated in the purifying step suitable for each. And each requires an independent purification system. Therefore, pumps essential for these purification systems are required for each system, and equipment costs and installation space are required.

Further, the magnet filter means 107 is
In the vicinity of the intake of the liquid to be purified W, the magnetic substance component in the liquid to be purified W has a high density in a ring shape, clogging occurs, and it becomes difficult for the liquid to be purified W to flow. As a result, the purification efficiency becomes poor.

A filter accommodating and purifying means 1 for the intermediate layer purifying system B
In No. 04, the polypropylene filters 104a that allow the liquid W to be purified to pass are set in multiple stages from coarse to fine, and as a result, unless the filter accommodating and purifying means 104 are arranged in multiple stages, it is practical. I won't. Simply using the filter 104a having a specific coarseness may cause a case where it cannot be captured, or conversely, a case where clogging occurs.
This leads to a reduction in purification efficiency.

Therefore, an object of the present invention is to provide a liquid purification apparatus that simplifies the purification system for the liquid to be purified, improves the efficiency of the liquid to be purified, and is inexpensive.

EXAMPLES Examples of the liquid purifying apparatus of the present invention will be described below.

<Embodiment 1> FIG. 1 is a structural view of a liquid purifying apparatus showing a first embodiment of the present invention in a use state.

In the figure, a waste liquid container 100 is used by polishing, grinding, electric discharge machining, hydraulic compression system, and other processes that flow from the outside (not shown) to contain a liquid W to be purified such as dirty water or dirty oil. To do. The liquid W to be purified, which is the target of the present embodiment, may be any liquid, and for example, any liquid W to be purified such as an aqueous system, an oil system, or an organic solvent can be used. The spirally magnetized rod-shaped magnet 1 is a spirally magnetized magnet, and its surface is rod-shaped. Of course, the rod-shaped magnet 1 magnetized in a spiral shape
May be in the state of a spiral rod-shaped magnet, and it is not always necessary that the circumference has the same diameter, and may be a direct spiral. The metal cotton 2 made of a magnetic material and arranged around the rod-shaped magnet 1 has its end portion restrained by the flange portion 3 and the lid portion 4, and is wound around the rod-shaped magnet 1 at a predetermined density. As the metallic cotton 2, cutting scraps of stainless steel are chemically stable and suitable. The flange portion 3 is the liquid W to be purified.
Through holes are formed to allow the passage of

The rod-shaped magnet 1 and the metallic cotton 2 are stored in a storage tank 5, and a supply part 5a is formed in the upper part so that the liquid W to be purified can pass in the lengthwise direction of the rod-shaped magnet 1 and the lower part. The discharge part 5b is formed in the. Further, the Teflon packing 6 is used to secure the adhesion between the storage tank 5 and the lid 4.

The supply part 5a at the upper part of the storage tank 5 guides the liquid W to be purified from the waste liquid storage container 100 through the pipe line 7 and the check valve 8. Further, the discharge part 5b at the lower part of the storage tank 5 guides the liquid W to be purified to the waste liquid storage container 100 via the pipe line 9, the check valve 12 and the pump 11. Further, a pressure gauge 13 with an electric contact, which operates at a display and a predetermined pressure, is arranged in the conduit 9 between the discharge portion 5b of the storage tank 5 and the pump 11.

As described above, the liquid purification apparatus 10 of the present embodiment.
Is a rod-shaped magnet 1 magnetized in a spiral shape, a metal cotton 2 made of a magnetic material arranged around the rod-shaped magnet 1, and a rod-shaped magnet 1.
And a storage tank 5 in which the metallic cotton 2 is built in and which allows the liquid W to be purified to pass therethrough in the lengthwise direction of the rod-shaped magnet 1.

Next, the operation of the liquid purification apparatus 10 of this embodiment will be described.

When the pump 11 operates, first, the check valve 1
2 is opened, and the inside of the storage tank 5 is depressurized by the pump 11. When the depressurized state exceeds a predetermined value, the check valve 8
Is opened, and the liquid W to be purified in the waste liquid storage container 100 is fed into the storage tank 5 via the supply unit 5a. The liquid W to be purified fed into the storage tank 5 flows from the upper part to the lower part in the metallic cotton 2 wound around the rod-shaped magnet 1,
It reaches the discharge part 5b through the flange part 3. Then, the purified liquid W after purification is discharged from the discharge portion 5b and returned to the waste liquid storage container 100.

During this time, when the pressure gauge 13 detects that the inside of the storage tank 5 is depressurized to a predetermined pressure state or more,
As an abnormal condition, the operation of the pump 11 is stopped. At this time, the check valves 8 and 12 are closed, and the liquid W to be purified does not flow back.

During this period, the liquid purification apparatus 10 of this embodiment is
It works as follows.

FIG. 2 is an explanatory view for explaining the operation of the liquid purification apparatus showing the first embodiment of the present invention.

In the figure, due to the magnetic field of the rod-shaped magnet 1 arranged in the center of the storage tank 5, the metallic cotton 2 is moved to the rod-shaped magnet 1.
Is magnetized in a spiral shape. Liquid purification apparatus 1 of this embodiment
In the initial use of 0, the liquid W to be purified is contained in the storage tank 5
Inside the rod-shaped magnet 1 in the longitudinal direction from the supply unit 5a to the discharge unit 5b
However, since the direction of the magnetic field is spiral, the particles of the substance desired to be removed induce other particles to adhere to the cotton wool 2. Therefore, the liquid W to be purified cannot flow in the longitudinal direction of the bar-shaped magnet 1 due to the adhered state, and the liquid W to be purified becomes a spiral flow W1. Therefore, the flow path of the liquid W to be purified is a multiple of the length of the rod-shaped magnet 1,
Meanwhile, the liquid W to be purified flows as indicated by an arrow in the figure, and W1 is guided in the metallic cotton 2 in a spiral shape. While the liquid to be purified W passes through the storage tank 5, the substance to be removed in the liquid to be purified W is magnetically removed by the rod-shaped magnet 1 and the metal cotton 2 to the metal cotton 2 by magnetic induction. Particles are induced, and the magnetic particles of the substance to be removed are attached to the metallic cotton 2 together with other particles. The particles to be removed in the liquid W to be purified have the adhering direction determined by the magnetic field, are efficiently filtered without clogging, and become purified liquid W2 to be purified.

In this embodiment, the case where the storage tank 5 is used alone has been described, but a plurality of the storage tanks 5 may be arranged in series according to the degree of purification, and a filtration function is provided. The rod-shaped magnet 1 and the metal cotton 2 wound around the rod-shaped magnet 1 can be made longer.

Further, the metal cotton 2 contained in the storage tank 5 has a narrower flow passage as the usage progresses longer, and needs to be replaced. Therefore, it is also effective to connect two liquid purification devices 10 of the present embodiment in parallel and provide a switching means for switching the two liquid purification devices 10. In other words, the liquid purification device 10 whose purification capacity has decreased during use can be switched to another liquid purification device 10 having the clean metallic cotton 2 by operating the switching means, without stopping the purification operation. Can be operated continuously.

In this embodiment, the magnetic cotton is used as the metallic cotton 2, but an optimum material may be selected depending on the type of the liquid W to be purified.

Its feature is that when the outside is dried, it absorbs water gradually, but it does not release water even if some pressure is applied.Acrylic acid polymer, corn starch, polyvinyl alcohol, etc. are the raw materials. . As its use, various water absorption such as paper diapers,
It is widely used as a water retention agent. The yarn used in this example is a yarn formed by using it together with a fiber such as acrylic resin, and also has a function as a fiber. Therefore, the fiber filter 31 of this embodiment is a filter having both the water absorption performance of the highly water-absorbent resin and the filtration performance of the fiber such as acrylic.

Inside the storage tank 33, there is stored a cylindrical body 35 having a flange 34 formed at its lower end and having a hole through which the liquid W to be purified is formed. Further, the inner lid 3 having a flow passage 36a whose central portion projects downward at the upper end of the cylindrical body 35.
6 is covered.

A supply portion 33a is provided above the storage tank 33, and the liquid to be purified W is guided from the waste liquid storage container 100 through the pipe line 7 and the check valve 8. Further, the discharge part 33b at the upper part of the storage tank 33 guides the liquid W to be purified to the waste liquid storage container 100 via the conduit 9, the check valve 12 and the pump 11. Further, a pressure gauge 13 with an electric contact, which operates at a display and a predetermined pressure, is provided in the conduit 9 between the discharge portion 33b of the storage tank 33 and the pump 11. A valve 38 for discharging deposits is arranged at the bottom 33c of the storage tank 33.
Is opened, the deposit accumulated in the lower portion of the storage tank 33 can be discharged to the storage container 39.

At the top opening of the storage tank 33, a lid 40 is provided.
Are connected to each other via Teflon packing 42 so as to closely contact each other. A cylindrical portion 41 is formed on the lower surface of the lid 40 so that the floating component of the liquid W to be purified can be contained. In particular, in this embodiment, the lid 40
A discharge portion 40a is formed at the center of the valve 43
When is opened, the floating component of the liquid W to be purified can be stored in the storage container 45 via the pump 44.

The end of the fiber filter 31 and the inner lid 36 are
A cushioning material 37 is disposed between the lower surface of the sheet and the lower surface of the sheet to prevent a gap from being formed therebetween. Further, a spiral spring 51 is arranged in contact with the inner diameter of the fiber filter 31, and the space between the pitches of the springs 51 holds the fiber filter 31 and at least one of activated carbon, pumice, zeolite, etc. accommodated therein.

The liquid W to be purified supplied from 3a passes through the particulate filter 32 between the storage tank 33 and the tubular body 35, and moves downward, and further causes a gap between the tubular body 35 and the fiber filter 31. Through the fiber filter 31 and the spring 5
From the gap between the pitches of 1 to pass through the particulate filter 52 made of a porous material made of one or more selected from activated carbon, pumice, zeolite, etc., which are accommodated therein, and from the flow passage 36a of the inner lid 36 to the storage tank. It flows into the discharge part 33b above 33.

Liquid to be purified W supplied from the supply unit 33a
While adsorbing the particulate filter 32 between the storage tank 33 and the tubular body 35, the particulate filter 32 is agitated to adsorb the substance to be purified contained in the liquid W to be purified, and the fiber filter 31. Absorb water with the water absorbent resin of
Chemically stable synthetic fibers are used to remove substances above a certain size. Further, the substance desired to be purified in the liquid W to be purified is adsorbed while stirring the particulate filter 52 housed inside the gap between the pitches of the springs 51. The floating component in the liquid to be purified W is discharged by the pump 44, collected by the storage container 45, and stored in the storage container 45 by opening the valve 43.

Large particles that could not be adsorbed by the particulate filter 32, after passing through the holes formed in the flange 34, are suddenly introduced into a large volume, and the flow velocity sharply decreases.
It stops at the bottom of the storage tank 33, aggregates, settles, and accumulates at the bottom. Therefore, by opening the valve 38, the deposit accumulated in the lower portion of the storage tank 33 can be discharged to the storage container 39. At this time, when the liquid W to be purified is oil or the like and has a specific gravity smaller than that of water, the water content is also reduced.
It settles to the bottom of 3, which can be discharged via valve 38.

By discharging the deposit in the storage tank 33 by the valve 38, the load on the fiber filter 31, the particulate filter 32, and the particulate filter 52 is lightened, and the effective period thereof is extended.

The liquid W to be purified is contained in the particulate filter 3
2, through the flange 34 and the fiber filter 31, flows to the central portion of the fiber filter 31, passes through the gap between the pitches of the springs 51 in the fiber filter 31, and is discharged from the particulate filter 52 to the discharge portion 33b. At this time, when the liquid W to be purified is oily, in addition to sludge, abrasion powder, and the like, moisture that has not completely settled at the bottom of the storage tank 33 is absorbed by the fiber filter 31 made of fibers made of superabsorbent resin. Is
Will be removed.

The storage tank 33 is provided with a flow path formed to pass both of the filters 52.

Therefore, in the present embodiment, the fiber filter 31 made of super absorbent resin fibers and the particulate filter 32 made of one or more adsorbents such as activated carbon, pumice and zeolite.
Further, it is used in combination with the particulate filter 52 and is provided with the storage tank 33 incorporating them, and even when used alone, the substance can be selectively removed, and the apparatus can be configured relatively easily.

Although the spring 51 of this embodiment corrects the position of the fiber filter 31, another small-diameter spring may be inserted in the central axis of the fiber filter 31 to facilitate passage of the liquid W to be purified. it can. The particulate filter 52 is filled between the spring 51 and the small diameter spring.
Of course, the spring 51 may be omitted, and the particulate filter 52 may be filled between the fiber filter 31 and the small diameter spring.

As described above, in the liquid purifying apparatus according to the first aspect of the present invention, the metallic cotton made of a magnetic material arranged around the spirally magnetized rod-shaped magnet is magnetized. Similarly, since a spiral magnetic path is formed around the rod-shaped magnet, the substance to be purified is magnetically adsorbed by the metal cotton while the liquid to be purified moves a distance several times the length of the rod-shaped magnet. Or the movement is blocked. Therefore, since the magnetic path is not formed in a flat plate shape in the vicinity of the supply portion of the liquid to be purified,
Therefore, the substance in the liquid to be purified is not magnetically adsorbed on the metal cotton and is not clogged.

Further, by magnetizing the rod-shaped magnet in a spiral shape, the liquid to be purified can be purified extremely efficiently. Further, since the distance required for purification can be easily secured, the device can be downsized and the cost is relatively low. Even in the maintenance, the effective period of the only consumable component, that is, the metal cotton, is longer than that of the conventional consumable component such as a polypropylene filter, which is economical. In addition, the clogged used metal cotton can be reused if it is dried to remove the attached substances, and the metal cotton is flammable and can be incinerated. Moreover, since the metallic cotton is inexpensive, the equipment and management cost can be kept low.

In the liquid purifying apparatus of the second aspect of the present invention, there is provided a fiber filter which is formed by winding a water absorbent resin and a synthetic fiber into a cylindrical shape, and which permeates the liquid to be purified in a radial direction thereof.
By incorporating a particulate filter made of a porous material arranged around the fiber filter and passing through both the fiber filter and the particulate filter, a substance having a predetermined particle size can be removed, and a substance to be purified can also be removed. When the liquid is oil, the water component contained in the oil is absorbed by the water absorbent resin. Then, the particulate filter made of the porous material can adsorb the fine particles in the liquid to be purified.

Therefore, the substance desired to be removed in the liquid to be purified should be circulated in a storage tank having a fiber filter made of highly absorbent fiber and a particulate filter made of a porous material such as activated carbon, pumice, or zeolite. As a result, in addition to substances such as sludge and abrasion powder, even a small amount of water present in the liquid to be purified can be absorbed and removed. In particular, the effect is remarkable when the liquid to be purified is oil, and of course, it can be normally used even when the liquid to be purified is water.

In the liquid purifying apparatus of the third aspect of the present invention, since the electrode is disposed at the bottom of the storage tank of the second aspect, the fiber to be purified and the particulate matter are ionized by ionizing the liquid to be purified. Facilitates adsorption to the filter. Therefore, when the liquid to be purified is water,
In particular, due to the effect of ionization, the force of ionic bonding promotes the aggregating action of the particulate matter, and the liquid to be purified can be efficiently purified.
