Description

DETAILED DESCRIPTION OF THE INVENTION In the treatment of industrial waste and general waste, treatment methods such as incineration or solidification are usually employed, but in either case, a kneading step is required in the treatment equipment.

The purpose of this kneading process is to supply, classify, and
These are kneading, dispersing and transporting.

However, a single device that is effective and simple for such applications has not yet been developed.

The present invention aims to provide a single sludge treatment device that can smoothly and easily process sludge and additives in accordance with the above objectives.

The present invention will be explained in detail below based on illustrated embodiments.
A is a crushing section that crushes the sludge, mixes additives, supplies quantitatively, and removes foreign matter, and continuously sends the sludge to the next kneading and pushing section B.

Reference numeral 1 denotes a greasing ring made of a wire mesh, a perforated plate, a lattice-like member, etc., provided at the center of a closed drum 3, which is the main body of the crushing section A, and has a cylindrical section b protruding from the center of the disk section α.

Incidentally, the disk portion α and the cylindrical portion b of the grizzly 1 can also be formed by disposing rods or ring-shaped rods with a required gap.

Reference numeral 2 denotes an elastic roller made of rubber or the like which is attached to the cylindrical portion b of the grizzly 1 in a circumferential manner.If necessary, the outer periphery of the roller 2 can be covered with an elastic material such as rubber having wear resistance.

3 is a closed drum attached to the machine frame C so as to cover the crushing section A, and a grizzly drive motor 10 is attached to the center of the upper part.
A sludge supply port 11 is opened in the vicinity thereof.

This grizzly drive motor 10 rotates the grizzly 1 via a speed reducer, a drive shaft 12 and an arm 13.

Reference numeral 4 denotes a rotating shaft disposed on the same axis as the drive shaft 12, and rotates via a motor 25 and a speed reducer.

5 is parallel to the rotating shaft 4 and the screw 7 of the rotating shaft 4
The two rotating shafts 4 and 5 are interlocked via a chain wheel 14 and a chain 15.

A scraper 6 is attached to the upper part of the rotating shaft 4 so as to be inscribed in the cylindrical portion b of the grizzly 1, and rotates in the opposite direction to that of the grizzly 1.

8, 8' are paddles provided between the screws T, 7' provided on the rotating shafts 4, 5, and 9 is a hopper attached to the kneading pushing part B, through which the rotating shafts 4, 5 run vertically.

16 is a discharge port opened at the bottom of the hopper 9; 17 is a rotating shaft of the roller 2; a roller drive motor 18; a pulley 19;
And the roller 2 is rotated in the opposite direction to the grizzly grip 1 via the belt 20.

Reference numeral 21 denotes an adjustment bolt of the rotating shaft 17, which adjusts the distance between the cylindrical portion b of the grizzly 1 and the roller 2 as appropriate depending on the physical properties of the sludge.

22 is a foreign matter discharge chute attached to one side of the drum 3;
3 is a guide plate attached to the disc part a of the grizzly 1, which prevents the input sludge from spreading outward due to the centrifugal force caused by the rotation of the grizzly 1, and guides it between the cylindrical part 2 of the grizzly 1 and the roller 2. do.

24 is attached close to the upper part of the disk part a, and the grizzly 1
A guide plate that guides the sludge that has passed between the disc part a of the grizzly 1 and the lower surface of the roller 2 to the lower side or the center side of the disc part α of the grizzly 1. is a fixed scraper 26 attached to the top of the hopper 9.
The rotating shaft 4 is scraped by the rotating shaft 4,
The screws 7 and 7' provided in the screw T are formed in a boat-shaped cross section as shown in FIG. are set 90° out of phase, rotating in the same direction in the gourd-shaped trough 9', so that the outer circumference of the paddles 8, 8' is constantly aligned with the other paddles 8', 8', and While rotating while maintaining a small gap with the inner surface of the trough 9', the volume inside the trough 9' changes continuously, and as the sludge is repeatedly compressed and sucked, sufficient kneading action is continuously performed in a short period of time. be.

A sludge supply chute 27 is attached to the sludge supply port 11 so as to be movable up and down, and is designed to primarily stabilize the supply amount by adjusting the gap between the chute and the disc portion α of the grizzly 1.

28 is an additive supply port.

The present invention has the above configuration, and has a sludge supply chute 2.
The sludge quantitatively supplied into the closed drum 3 through step 7 is
As the grizzly 1 rotates, the sludge is crushed and pushed by the grizzly 1 and the roller 2 rotating in the opposite direction, and most of the sludge passes through the cylindrical part b of the grizzly 1 and passes through the scraper rotating in the opposite direction to the grizzly 1. The sludge is scraped off by the scraper 6 and falls downward due to its own weight and the feeding action caused by the twisting of the scraper 6.

Further, the sludge that has passed between the disc part a of the grizzly 1 and the lower surface of the roller 2 is guided by the guide plate 24, passes through the disc part α or the cylindrical part b of the grizzly 1, and falls. .

At this time, foreign matter mixed into the sludge cannot pass through the grizzly 1 and is separated through the discharge chute 22.

The sludge that has passed through the grizzly 1 and fallen due to its own weight is deposited in the hopper 9, and the screws 7. The material is pushed in by the paddles 7', kneaded and dispersed by the paddles 8 and 8', and then extruded from the discharge port 16.

The screws 7, 7' and the paddles 8, 8' have a boat-shaped cross section and rotate in the same direction within a trough 9' having a gourd-shaped cross section, and the outer periphery of the paddles 8, 8' is constantly While rotating while maintaining a small gap between the paddles 8', 8 and the inner surface of the trough 9', the volume inside the trough 9' changes continuously and compresses and suctions the sludge repeatedly, resulting in sufficient mixing in a short time. While the action is continuous, the self-cleaning action prevents sludge from sticking and short passes.

The required degree of kneading can be maintained by combining paddles with different helix angles, and the extrusion effect can be produced by the helix angles of the screws and paddles, so that high viscosity sludge can be continuously and smoothly discharged.

As described above, a grizzly made of a wire mesh or the like having a cylindrical part formed in the center of a disc part is rotatably mounted in a closed drum having a sludge supply port and a discharge chute, and a roller is attached to the cylindrical part of the grizzly. A hopper is connected to the lower part of the crushing part which is circumscribed by the grizzly and a guide plate for separating foreign matter is provided on the grizzly, and the upper part has a scraper which is inscribed in the cylindrical part of the grizzly so as to pass vertically through the hopper, and the lower part A kneading pushing section is provided in which a rotating shaft equipped with a screw and paddles and a rotating shaft equipped with screws and paddles that mesh with each other are arranged side by side, so that the input sludge is discontinuous and does not clump. Even if these substances are mixed in, it is possible to average them out, impart smooth fluidity, and continuously knead them, as well as to separate foreign substances and impart extrusion force to the kneaded material.

In addition, by closing the entire system, it is possible to suppress the remaining of processed materials and the emission of odors to the outside, which has industrially beneficial effects.
