Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a line mixer having no mechanical driving part.

[0002]

2. Description of the Related Art A line mixer encloses a turbulence generating member (element) having a special structure for generating a turbulent flow in a fluid in a cylindrical tube, and aims to agitate and mix two or three fluids flowing through. Equipment to shorten the stirring and mixing process,
It has many features, such as reduced equipment costs, improved on-site work environment (easy odor control), and reduced power costs.

[Problem to be solved by the invention]
In the field of sewage treatment such as sewage, when a conventional line mixer is applied for the purpose of stirring and mixing, it is often difficult to achieve the purpose for the following reasons. In human waste, sewage sludge, etc., foreign substances such as human hair, animal and plant fibers, chemical fibers, vinyl pieces, metal pieces, etc. are mixed and adhere to and accumulate on elements in the line mixer, obstructing the flow of fluid, and in the worst case Blockage and the flow stops. When the flow of the fluid is hindered or stopped due to the above reasons, it is necessary to stop the operation of the entire plant, remove the line mixer unit from the line, and remove foreign matter. The present invention solves the drawbacks of the conventional type, and even if a clogging phenomenon occurs, without removing the line mixer unit from the line, while continuing operation,
An object of the present invention is to provide a line mixer that can easily remove a clogging substance and return to the current state.

[0004]

According to the present invention, a plurality of turbulence generating rods are inserted and removed from the outer peripheral side of a cylindrical tube at right angles to the flow direction of the fluid and the insertion direction is changed along the flow direction of the fluid. This is a line mixer that is freely inserted.

[0005]

In the line mixer of the present invention, the flowing fluid is disturbed and mixed by a plurality of turbulent flow generating rods which are inserted in the cylindrical tube at a right angle to the flow direction of the fluid. Gradually, foreign matter in the fluid becomes entangled with the turbulence generating rod, and the flow of the fluid is hindered or stopped. At that time, by pulling out the turbulence generating rod on the uppermost stream side, the entangled foreign matter is scraped off by the cylindrical pipe and is moved downstream, so that the turbulent flow generating rod is inserted into the original position. Next, the foreign matter entangled with the next turbulence generating rod on the downstream side is removed by the same operation as described above, flows downstream, and is inserted into the original position. In this way, the foreign matter entangled with the turbulent flow generation rod in the downstream direction is removed, and it is not necessary to remove the line mixer or stop the operation of the entire plant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a cylindrical tube incorporated in a piping line, and flanges 2 are provided at both ends of the cylindrical tube 1. From the outer peripheral side of the cylindrical pipe 1, solid or hollow turbulent flow generating rods 3 are inserted so as to pass through the axis inside the cylindrical pipe 1, and these turbulent flow generating rods 3 are inserted in the fluid flow direction (FIG. At right angles to the flow direction of the fluid (see FIG. 1) at a pitch l (see FIG. 1) and at an angle θ between the turbulence generating rods 3 (see FIG. 2), a plurality of pieces are inserted while changing the insertion direction. ing. The thickness, the number, the pitch l, and the angle θ of these turbulence generating rods 3 may be set to appropriate conditions by experiments and the like. Further, the turbulence generating rods 3 are inserted into the cylindrical tube 1 so as to be freely inserted and removed. For example, as shown in FIG. The flow generating rod 3 is inserted and penetrated into the cylindrical short pipe 4 via the elastic sealing material 5, and a cap nut 6 penetrating the turbulent flow generating rod 3 is screwed and held on the cylindrical short pipe 4. , Loosen the cap nut 6 and pull out the turbulence generating rod 3,
Insertion is free, tighten cap nut 6 and turbulence generating rod 3
Can be fixed

[0007]

As described above, the line mixer of the present invention generates a plurality of turbulent flows by changing the insertion direction at right angles to the flow direction of the fluid from the outer peripheral side of the cylindrical tube along the flow direction of the fluid. It has a simple structure in which a rod can be freely inserted and removed, and has all the features of conventional line mixers.
Without removing the line mixer, it is possible to easily remove foreign substances while continuing the operation, and it is possible to greatly increase the efficiency of the whole plant, which is a very advantageous effect.
