Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a gas-liquid mixing injection cleaning device, more specifically, a device used in a filtration device for solid-liquid separation, for example, by washing sludge such as sludge adhering to a filter medium, so that the filter medium can be repeatedly used endlessly. This invention relates to a gas-liquid mixing jet cleaning device that can be used for cleaning.

(Background Art) Conventionally, there are two methods of using filter media such as filter cloth and metal steel used in filtration devices for solid-liquid separation: a disposable method and an endless method of repeated use (in the former case, Since the filter media is disposable, even if sludge, etc. adheres to it, it will not affect the filter media as it will be discarded at the same time. However, the biggest drawback is the high cost, which poses a serious problem that makes it difficult to use in practical terms. Ta.

On the other hand, in the latter case, since it is used repeatedly, it is very economical, but there are problems in cleaning or removing sludge and the like that adhere to the filter medium. That is, a water jet cleaning method has conventionally been commonly used as a method for cleaning filter media. However, this water jet cleaning method requires the use of a large amount of cleaning water, which is very uneconomical, and there are also problems in how to post-process the cleaning water.

In order to solve the problems of the water jet cleaning method, some Vc air cleaning methods have been used, but in this air cleaning method, the cleaning ψ removal agent for the deposits such as sludge adhering to the filter media is In particular, if the viscosity of the deposits is high, the removal efficiency is even worse, making it unsuitable as the cleaning method 9 in practice.

(Problems to be Solved/Technical Objectives) In order to solve the above-mentioned problems, the present invention provides a cleaning device for filter media, etc., which uses an extremely small amount of cleaning liquid and has very high cleaning efficiency.

(Disclosure of the present invention) In order to achieve the above-mentioned object, the present invention comprises a rotatable cylinder (1) having a plurality of through holes in the peripheral wall, and an inner cylinder (1) with 'R-pores fitted onto the outside of the inner cylinder (1). and a fixed outer cylinder (3) having
Said inner cylinder (1) K high-pressure gas is pumped into the outer cylinder (8)
A configuration in which a mixture of high-pressure gas and cleaning liquid is intermittently injected onto the object to be cleaned by intermittently injecting the mixture from the exhaust hole of the cleaning liquid and jetting the cleaning liquid before or after the high-pressure gas injection from the exhaust hole. I made it.

With such a configuration, the mixture can be intermittently sprayed onto the object to be cleaned, such as a filter medium, thereby generating vibrations in the object to be cleaned. etc. can be removed with high precision, enabling efficient winter cleaning. Furthermore, since it is only necessary to inject a small amount of cleaning liquid into high-pressure gas, the amount of cleaning liquid used is extremely small and high-precision cleaning is possible, achieving the above objectives. It became possible.

(Effect) Since the present invention intermittently injects a mixture of high-pressure gas and a small amount of cleaning liquid onto the object to be cleaned, vibrations are generated by the intermittent spraying on the object to be cleaned, and the vibrations cause sludge to adhere to the object to be cleaned. At the same time as the phenomenon of peeling occurs, the cleaning solution further increases the peeling, and even firmly adhered substances can be removed extremely smoothly, resulting in an exceptional effect of greatly increasing cleaning efficiency. .

Furthermore, compared to conventional cleaning methods that use only cleaning liquid, the amount of cleaning liquid used is extremely small, so there is no problem with post-treatment of the cleaning liquid (as a cleaning device, it has a particularly unique effect compared to conventional devices).

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the inner cylinder (1), in which circular through holes (2) of four ICs are arranged at regular intervals in the circumferential direction of the inner cylinder (1).
is drilled. Figure 2 is a perspective view of the outer cylinder (8) that is fitted onto the inner cylinder (1), and shows one exhaust hole (there are nine exhaust holes) in the same circumferential direction as the through hole (2). It will be done.

Next, FIG. 8 is a usage state diagram of the cleaning device as an example, in which the inner cylinder (1) is configured to be rotatable by a shaft cylinder (5) K fixed to one end, and the outer cylinder (8) is configured to be rotatable. is the inner cylinder (1)
The exhaust hole (located with an upward slope and fixed between the support plate (6) and the bearing (7). (8)
is a pulley externally fixed to the shaft cylinder (6), and a bell (QOI) is hung between it and the motor shaft (9).

The circle is a rotary socket into which one end of the shaft cylinder (5) is fitted via the sealing member α2, and the sum is the rotary socket.
The compressor, α9, is connected to the Kerato circle via a hose circle, and the connecting pipe, α, has one end connected to the exhaust hole (4) of the outer cylinder (8), and the other end connected to the socket (161). The decoy is a cleaning brush body energized via a spring α mark at the tip of the injection pipe αη, and the company is a 0 second brush of the cleaning brush body (
Ring-shaped Fretan sealing material inserted in 211,
(The above socket) (1G + internal pressure injection nozzle @ shows the liquid delivery pipe that sprays the cleaning liquid.

Since the above embodiment has the above configuration, it is possible to avoid deposits such as sludge (
When cleaning an endless filter medium that filters water, as shown in Figure 8, with the cleaning brush body 0 seconds installed on the back side of the filter medium (VC), turn on the compressor αJ and motor (a). Compressor (13) when driven
The high-pressure air blown out from the rotary socket (111) is forced into the rotary socket (111) through the hose α4, and from the socket circle into the inner cylinder (111) through the shaft cylinder (5).

At this time, the inner cylinder (1) is rotated by the pulley (8) which rotates via the belt αO by the drive of the motor (A).
) rotates, so the cylinder (1) is also in a rotating state at the same time.

Since the outer cylinder (Ilk) is in a fixed state with respect to the rotation of the inner cylinder (1), the pressurized air flows through the through hole of the inner cylinder (1) (no...℃outer cylinder (8) Since the exhaust will be exhausted from the exhaust hole (4) of the outer cylinder (8) only when the exhaust hole (4) of the outer cylinder (8) and the exhaust hole (4) of becomes.

Therefore, the air exhausted from the exhaust hole (4) is intermittently injected from the injection tube aη via the connecting pipe α8.

Moreover, since the cleaning liquid is injected at the socket part αG in response to the air intermittently injected from the connecting pipe αS, the air and the cleaning liquid are mixed to form a mixture, and the air is injected from the filter medium (8 ) is intermittently ejected onto the back side of the body.

The intermittent injection causes intermittent vibrations on the back side of the filter medium (5), and as a result, a peeling phenomenon occurs in the deposits such as sludge attached to the filter medium (25), and cleaning liquid is mixed into the intermittent air injection. Therefore, the peeling becomes even better, and the cleaning efficiency of the filter medium device becomes significantly better. Therefore, the filter medium can be used repeatedly, making the filter medium very economical.

Furthermore, in this embodiment, the cleaning brush body α mark is attached to the tip of the injection tube aη, and a ring-shaped sealing material is inserted into the brush (211) to surround the injection port, so that the injection This has the advantage that there is no pressure leakage and the injection efficiency is significantly improved.

In this embodiment, air is intermittently injected at high pressure, but when the air is compressed and injected at high pressure, air vibration generates ultrasonic waves and an ultrasonic phenomenon occurs.
The vibration effect exerted on the wafer is further enhanced, and the peeling and cleaning efficiency is superior to that of the above embodiments, but the generation of ultrasonic waves is not necessarily a condition of the present invention.

In addition to water, the cleaning liquid may be of any type, such as steam, foamy liquid, or chemical liquid, as well as the inner cylinder (1) and outer cylinder (8).
In other words, the relationship between the through hole (2) for intermittent injection and the exhaust hole (4, l) is not limited to the above embodiment;
The shapes of 2) and (4) are not limited in any way. The point is that by rotating the inner cylinder (1), the fixed outer cylinder (
Any structure is sufficient as long as the exhaust hole (4) of 8) and the through hole of the inner cylinder (1) are intermittently aligned with each other so that air is intermittently injected from the exhaust hole (4).

In addition, in the above embodiment, air is intermittently injected from the exhaust hole (4), and then the cleaning liquid is squirted at the socket mark to generate a mixture; however, the present invention is not limited to this. The structure may be such that the mixture is mixed with the cleaning liquid and then intermittently injected as a mixture from the exhaust hole (4).For example, there is an embodiment shown in FIG.

In the case of this embodiment, the rotary socket part [11] is provided with a cleaning liquid injection nozzle (2) connected to the K liquid feed pipe (2), and the cleaning liquid is injected into the socket part 11υ at the nozzle (23+). Therefore, in this embodiment, the cleaning liquid is injected into the high-pressure air pumped from the compressor αJ to form a mixture, which is intermittently injected from the exhaust hole of the outer cylinder (3).

In this embodiment, a plurality of through holes (inner cylinder (1) K
5 points are thrown at regular intervals in a spiral pattern,
In addition, the outer cylinder (8) has a downward slit-shaped exhaust hole (4).
is formed. Therefore, in this embodiment, the inner cylinder (
1), the mixture is intermittently injected from the downward exhaust hole (4) of the outer cylinder (8).

In this embodiment as well, the shape of the through hole (powder and exhaust hole (4) does not matter at all. Also, in the above embodiment, the shape of the outer cylinder (3) does not matter.
) may have a structure in which the mixture is injected into the inner cylinder (1) from both sides of the cylinder (1).

As an example of the use of the cleaning device of the present invention, the object to be cleaned is by no means limited to filter media, and the range of use thereof is extremely wide, as long as the mixture is sprayed to remove and clean deposits.
