Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a device for clarifying and reusing industrial wastewater (hereinafter referred to as raw water), underground water wall construction, on-site hammering and other civil engineering treatment water, sludge water (raw water). For the purpose of clarification, reuse, or dumping into rivers, the sea, etc., and further to filtration equipment for various contaminated wastewater such as wastewater from household waste, domestic wastewater, or sewage drainage. In the place where, the solid-liquid separation device was separated into the internal component equipment and the outer component equipment separately, and after manufacturing and transporting each separately, it was possible to assemble with one touch and accurately at the installation site. The present invention relates to an assembly type solid-liquid separation device for raw water such as sludge water.

2. Description of the Related Art Conventionally, this type of solid-liquid separation device is mainly composed of an integrated structure, and normally, a container body forming an outer shell of the solid-liquid separation device, an aggregating chamber of the solid-liquid separation device, and a separation unit. The internal structure that constitutes the body adopts an integrated assembly structure. As a part of the improvement of the above-mentioned prior art, the applicant of the present invention detachably mounts a flocculation chamber on a cylindrical container body having a plurality of settling / separating chambers (separation plates). We have already acquired three rights regarding inventions and inventions of the system. That is, it is a precipitation separator of JP-B-63-44402 or a separator of JP-B-2-15525.

Further, although the prior art and the document thereof are not mentioned, for example, in addition, in the oil separation device, a structure in which the oil absorption filter device is detachably attached is partially implemented, or a technique similar thereto. The literature is also scattered.

[0004]

The method for making the flocculation chamber and the like detachable has certain advantages. For example, it is useful in terms of maintenance management such as cleaning when the container body and filter become dirty, repair at the time of failure, replacement of parts, etc.
Device compatibility, etc. However, since detachable components are still limited to some components, some problems can be considered in terms of actual transportation, production, or cost. Specifically, during transportation, especially during long distances or during export, the distance between the inner wall surface of the container body and the separation plate (the slight downstream area) becomes inaccurate or uneven, and the flow is rectified. Is often not secured. example
For example, when the container bodies are stacked horizontally, such a tendency often occurs, which is a problem faced by the present inventor when actually transporting or exporting.

In particular, the above repair or correction is difficult,
It is possible to say that the above-mentioned integral structure is impossible. Of course, it seems possible if a skilled person makes full use of his time and experience, but this is a difficult task, and in reality it can be said that it is impossible. Further , many problems remain because the rectified flow-down situation is not secured, and the correction, maintenance, and the like, including the function, are complicated and troublesome. Of course, if it is an integral structure,
It is bulky, and this point seems to be one of the challenges.

On the other hand, in terms of manufacturing, on the contrary to the outer shell component equipment of the solid-liquid separation device (hereinafter, in principle, outer shell component equipment) which can be manufactured by a relatively shallow experience or by an ordinary factory or a falling operation. Producing highly-experienced persons or specialized factories, and internal component equipment of solid-liquid separation equipment (hereinafter, in principle, internal component equipment) mainly for single product work at one factory or at one place There are issues such as poor performance and increased costs.

[0007]

In view of the above, the present invention provides
The outer component and the inner component are completely separated.
However, an assembly method that allows easy assembly on site
It should be configured so that the flow condition is not rectified and bulk is eliminated. In addition, in order to improve workability and reduce costs,
The following configuration is adopted.

That is, according to the present invention, an annular flocculation chamber composed of a supernatant water pipe provided in the center and a cylindrical body surrounding the supernatant water pipe, and a tangential direction of the flocculation chamber A raw water inlet pipe that opens, a supernatant water discharge pipe that is connected to the supernatant water pipe and opens outside the aggregation chamber, and a skirt-shaped separator that expands downward from the lower end of the supernatant water pipe body. Between the internal component equipment of the solid-liquid separation device consisting of, and the pipe to which the internal component equipment is inserted and the raw water introduction pipe and the supernatant water discharge pipe are respectively connected, and the skirt of the separator. the inner wall surface slightly falling basin is formed, and the outer configuration equipment of solid-liquid separator having a cylindrical shape made of a lower cylindrical portion separating chamber is formed below the separator, the outer

[0009]

Next, the operation of the present invention (transportation or assembly condition) will be described. As described above, the outer component equipment and the inner component equipment are manufactured separately (in some cases, they are manufactured in different factories or companies), and since each of these equipment is individual, it is lightweight and easy to handle. Be simple. In the case of export, etc., it is possible to manufacture only the internal component equipment domestically or at a specialized factory and to easily export the external component equipment at the export or installation location according to its technical level. There is a functional effect that the technical level such as the above can be utilized and a rectified flow-down situation can be secured. In addition, it is possible to transport them individually,
Therefore, there is an advantage that the bulkiness during transportation can be eliminated. When the sludge scratching device is provided in the solid-liquid separation device (usually, it is provided), it is desirable that the sludge scraping device is also manufactured individually.

As described above, the separately manufactured outer shell component, the inner component and the sludge attracting device are assembled. First, install the outer shell components (of course, after assembly,
(In some cases, it may be installed), after that, first place the sludge scraping device equipped with the scraping plate on the inner bottom surface of the outer component equipment,
Further, a rotary shaft that constitutes a part of the sludge proximity device is provided upright toward the upper opening of the outer component device. Next, the internal component equipment is assembled.First, the internal component equipment is inserted into the large space between the rotation shaft that is erected and the inner wall surface of the outer component material, and the rotary shaft is placed exactly on the separation body and the upper part. The clear water pipe is arranged so as to surround it. At this time, the locked device of the internal component device is hooked on the locking device of the external component device, the aggregation chamber and the separator of the internal component device are arranged in the external component device, and The pipe is connected to the raw water introduction pipe and the supernatant water discharge pipe of the internal components via flexible pipes. Through the above operations and procedures
The internal components to the outer components.
A separation settling chamber is formed in the lower part of the outer shell constituting device, and between the inner wall surface of the outer shell forming device and the skirt of the separator provided above the separation settling chamber. ,
It is important to assemble a small flow downstream area formed of an annular shape so that this flow downstream area can be used for treated water to flow down (the outer component equipment and inner component equipment are assembled by bolts). It is integrated by fixing means such as.).

As described above, the drive device for the sludge attracting device is installed on the base on the assembled internal component equipment, and is linked to the rotating shaft which has been already erected. By this
The assembly of the solid-liquid separation device is completed.
Explain the separation.

That is, in this solid-liquid separation device, the raw water (raw liquid) introduced into the coagulation chamber from the raw water supply pipe is slowly fed from the connecting direction of the coagulation chamber. While being refluxed, the coagulation aid and the raw water are mainly mixed here to be converted into flocs having a better sedimentation property. The raw water containing flocs having a good sedimentation property is guided to the separator and flows down on the surface of the separator with a slow speed. In the sinking process, the raw water comes into contact with the separator, and the frictional resistance of the raw water makes the water slower, and the physical contact shock causes the flocs to grow even larger and is separated by the frictional resistance of the separator. Before
As described above, solid-liquid separation is performed smoothly and rapidly. Then, the treated water containing flocs is guided to a separation and settling chamber having a large area, where it is gravity separated.
The flocs that are gravity-separated further increase in size, and gradually settle toward the bottom of the sedimentation separation chamber, and are pushed onto the bottom having a gentle slope. After that, the flocs are discharged to the outside of the device through the sludge discharge pipe. Further, the treated water that is gravity-separated becomes a supernatant liquid, rises in the separation-sedimentation chamber, and is temporarily retained in the convergence of the separator, and during this retention, the fine sludge contained therein is further separated,
Only truly clarified supernatant water rises at a slow speed. The supernatant water is discharged to the outside of the apparatus or reused through the supernatant water pipe, the supernatant water discharge pipe and the pipe. By repeating the above-mentioned operation, the raw water introduced into the solid-liquid separation device is sequentially and accurately subjected to sedimentation separation treatment.
