Description

DETAILED DESCRIPTION OF THE INVENTION (Objective of the Invention) (Industrial Application Field) The present invention relates to a management system for, for example, drainage pipes for household gray water, filth, etc.

<Background of the Invention> In general households, commercial facilities, public facilities, and even factories, it is necessary to manage particularly heavily polluted drain pipes, but this has not always been done adequately in the past. In other words, conventional methods for cleaning such pipes include methods of chemically dissolving and removing dirt, and methods of physically inserting a cleaning hose, etc., but in the latter case, for example, the pipes are complicated Of course, this cannot always be done satisfactorily in cases where pipes branch, merge, or bend.Of course, for such pipes, it is recommended to install traps, manholes, rakes, etc. in the middle of the pipe for the purpose of cleaning etc. from the beginning. However, this kind of contamination of drain pipes is often found in all areas of the pipe, especially in areas that are placed almost horizontally.
Cleaning these at regular intervals will only remove the dirt that has accumulated there, and once removed, the dirt that has accumulated on the inner surface of the pipe will simply move again. However, this method is far from perfect.

(Technical matters attempted to be developed) The present invention was made in view of this background.
Equipment that can inject cleaning liquid at high pressure is installed in the middle of a pipe for household inv# water, etc., so that the inner surface of the pipe can be easily cleaned from the outside.

(Structure of the Invention) Means for Achieving the Object> That is, the management system for pipelines, etc. of the present invention has a structure in which a nozzle for injecting a management fluid toward the inner surface of the pipeline is formed in one or multiple stages in the middle of the pipeline for transferring fluid. The invention is characterized in that all or part of them are operated constantly or intermittently, thereby achieving the above object.

(Example) Examples of the present invention will be specifically described below with reference to the drawings. First, reference numeral 1 is a building to which the present invention is applied, and a pipe line 2 inside the building 1 is to be treated. This pipe line 2 includes a drainage branch pipe 3 directly connected to a sink, a wash basin, etc., and a drainage main pipe 4 in which several branch pipes are concentrated. Of course, this drainage main pipe 4 is also grouped together for each house in the building 1 and further led to an external drainage pipe or the like. A jet injection section 6 is provided at each predetermined location in such a pipe line 2, and a management fluid is fed under pressure to this jet injection section 6, and a high-pressure pump 8 is connected to this via a liquid supply hose 7. Control fluid is sent from In addition, the high pressure pump 8 has a driving force of tJs1M.
At the same time, the management fluid is stored in the tank T. Of course, the management fluid may be simply water, or an appropriate chemical solution or the like may be added thereto for cleaning and disinfection of the pipe line 2.

It should be noted that the pressure of this pressure-fed management fluid is preferably about several 10 kg/cs to several 100 kg/e11, as an example, but furthermore, regarding the zero-order jet injection part 6, which can select an appropriate pressure in the range before and after this. Specifically, the reference numeral 10 is a guide ring wound around the side body of the pipe line 2 in the jet injection part 6, and in consideration of the case where it is retrofitted, the guide ring 10 is divided in half in the diametrical direction. is,
These are connected in an annular manner by bolts 11.

Of course, if the guide ring 10 is provided from the construction stage of the conduit 2, the annular guide ring 10 may already be used.

This guide ring 10 is formed with several guide ring side injection holes 12, and the guide ring 10 is connected to the pipe line 2.
When attached to a pipe, a pipe-side injection hole 13 is further bored in the side trunk of the drainage branch pipe 3 at the same location as the injection hole. For example, if the drainage branch pipe 3 is made of a vibrator such as vinyl chloride or a metal pipe, it is formed by the rolling action of an electric drill. It also acts as a hole. This guide ring IO is further provided with an outer ring 15 so as to cover it from the outside, and this ring is also divided into two in the diametrical direction.
The configuration is such that both are tightened with bolts 16. Inside this outer ring 15 is a guide ring 10.
A liquid feeding section 17 is formed with a space formed at a constant interval between the two, and a connecting hose 18 is provided on the outside
Form an extension. Of course, this connection hose 18 can be pulled out to an appropriate location, and for example, if various machines for supplying controlled fluids, such as high-pressure pumps, etc. are installed in the building 1, it may be directly connected to them. Alternatively, it may be connected to the liquid feed hose 7 from there.

In addition, when these facilities are not installed in the building 1 and are driven by a high-pressure control fluid pumping device mounted on an external vehicle, for example, the connection hose 18 is a liquid feeding hose from the high-pressure pump 8. 7 and is pulled out to a position where it can be easily connected.

The specific configuration of this jet injection section 6 can be various. For example, the simplest method is to install an injection nozzle 20 in the middle of the pipe line 2 and connect it directly thereto, as shown in FIG. 4(a). The control fluid may be supplied from the hose from day 1, and the jet injection unit 6 mentioned above is attached to the outer circumference of the pipe 2, for example, as shown in FIG. 4(b). As shown in FIG. 2, the residual light 24 formed at the bottom of the sink 23 in the sink 22 may be provided inside the residual light 24, that is, the annular main body 25 may be provided inside the residual light 24, and An appropriate number of injection nozzles 20 are provided. The above-mentioned embodiments have been explained mainly for general households, etc., but they can also be applied to commercial cooking facilities, various public buildings, factories, etc.
Alternatively, it can also be applied to pipelines for production and manufacturing in factories and the like.

The present invention includes the specific members described above,
With this, the management of the pipe line 2 is carried out as follows. First, the high-pressure pump 8 is activated, and the management fluid is guided from the liquid supply hose 7 to the jet injection part 6 via the connection hose 18. In the embodiment shown in the figure, the fluid is guided from the liquid feeding section 17 to each pipe-side injection hole 13, from which the management fluid is injected under high pressure into, for example, the drainage branch pipe 3.

Of course, this injection may be performed at regular intervals using a timer or the like, or it may be activated as appropriate when the contamination of the pipe 2 has progressed. The fluid stream comes into contact with the inner circumferential surface of the drainage branch pipe 3 and flows downstream along the inner circumferential surface of the drain branch pipe 3, so that the waste is sent downstream while cleaning the inner surface. Of course, at this time, the injection direction of the management fluid is to be directed in an appropriately preferable direction, and it is desirable that the injection direction be substantially downstream. Abnormal odors tend to occur when filth is agitated, but in the present invention, by injecting the odors downstream through the management fluid stream, the upstream area is accordingly reduced to a negative pressure state. Thus, the odor is sucked into the pipe 2. The dirt and the like separated from the inner surface of the pipe line 2 in this manner are collected on the downstream side under the injection pressure of the management fluid. In addition, in accordance with the present invention, when the jet injection part 6 is provided to the pipe line 2, as described above, it can be provided in one stage or in multiple stages, and the jet injection part 6 can be provided in a single stage or in multiple stages, and the jet injection part 6 is particularly concentrated in areas where filth and the like are likely to be concentrated. It is also possible to select a reliable management method depending on the situation of the pipe line 2.

(Effects of the Invention) As described above, the present invention is provided with a jet injection section 6 that performs a cleaning action on the pipe line 2, and can be easily cleaned by simply supplying a high-pressure control fluid to this jet injection section 6. This can be done by cleaning the inside of the pipe. In addition, during this cleaning, since the filth and the like are collected on the downstream side, the management fluid is moved to the downstream side, and no abnormal odor is generated during the work.
