Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to a mixer for mixing liquid or solid waste with a pulverizing agent and converting the waste into a non-polluting powder.

For example, if you put a finely powdered powder containing silica lime and a deodorizing agent into a conventional mixer, then add waste oil and rotate the conventional mixer, the waste oil will spread the powder around it. It absorbs into many beads.

However, since waste oil that has not absorbed the powdering agent exists in the center of the ball, if it is disposed of as is, the waste oil may seep out and cause a pollution problem.

This is because the beads of waste oil produced by conventional mixers are relatively large.

Furthermore, the conventional mixer required a long time to mix the waste oil and the powdering agent, resulting in an inefficient process.

Therefore, the present invention provides a mixer that eliminates the drawbacks of the conventional type as described above, and the present invention will be explained in detail below with reference to the drawings.

As shown in FIGS. 1 to 8, the mixer 1 of the present invention consists of a rotating drum 2, a rotating frame 3, and an agitation shaft 4. The rotating drum 2 holds waste oil and powdering agent on its inner peripheral surface. A partition plate 5 is erected on the inner peripheral surface, and the outer periphery is connected to a guide roller R.
At the same time, the gear 7 is held by the driving force of the drive motor 6.
, 8.9, the rotary drum 2 is rotated.

The rotating frame 3 is located inside the rotating drum and rotates around the central axis of the drum by a drive motor 10,
A large number of first stirring rods 12 are installed along the inner peripheral surface of the drum in a plurality of main ribs 11 parallel to the central axis and radially toward the central axis.

The stirring shaft 4 is supported by bearings 13, 14, and 15 on the central axis of the drum, and is supported by the inner frame 3.
A large number of second stirring rods 16 are installed radially in an intricate manner between each of the first stirring rods 12 of the drive motor 1.
Rotated by 7.

A spiral barrier 18 is provided on the inner circumferential surface of the rotating drum 2 in a spiral shape extending across the partition plate 5 and extending along the inner circumferential surface of the rotary drum 2. A spiral barrier 19 similar to that described above is provided slantingly as shown by diagonal lines in FIG.

Next, the operating order of the mixer 1 of the present invention will be explained. First, the powdering agent is introduced through an inlet with a lid (not shown) opened in the rotating drum 2, and the inlet is sealed, and the rotating drum 2 is driven by the drive motor. Rotate for a while at step 6 to distribute the powdering agent evenly within the mixer.

Next, the operation of the rotating drum is stopped, waste oil is poured into the inlet with a lid, the inlet is sealed again, and the drive motors 6, 10,
17 to rotate the rotating drum 2, rotating frame 3, and stirring shaft 4, respectively.

Then, the rotating drum 2 and stirring shaft 4 rotate in the same direction, and the rotating frame rotates in the opposite direction.

The powdering agent and waste liquid are rotated upward along the inner peripheral surface of the drum 2 by the partition plate 5 of the drum 2, and then descended from above the stirring rods 12, 16.

Then, the first stirring rod 12 installed in the rotating frame 3 and the second stirring rod 16 installed in the stirring shaft 4 rotate in opposite directions, so that the descending waste oil is absorbed by the respective stirring rods. The waste oil is cut at high speed and quickly mixed with the dusting agent, and the waste oil absorbs the dusting agent around it and forms beads.

The bead-shaped waste oil is carried upward again by the partition plate 5 and descends both ways, and during the descent, it is shredded again by the stirring rods 12 and 16 and becomes finer, and then it descends to the lower part of the rotating drum 2. Waste oil and powdering agent are stored in spiral barrier 1 of drum 2.
8 to the right in FIG. 1, and the spiral barrier 19 of the rotating frame 3 to the left.

At this time, the waste oil and the powdering agent are mixed, and the beaded waste oil is divided into finer particles.

In this way, the waste oil absorbs the powdering agent and turns into a powdered non-polluting substance.

To discharge such powdered waste oil from the mixer,
The rotating drum is stopped with its discharge port (not shown) facing downward, the cover of the discharge port is opened, and the rotating frame and stirring shaft are driven.

The powdered waste oil discharged in this way is used as a landfill or as a soil conditioner.

At the beginning of the waste oil powdering work, the viscosity of the waste oil has a large effect, so by changing the rotation direction and rotation speed of the rotating drum 2, rotating frame 3, and stirring shaft 4, it will start smoothly and continue for a while. By setting the rotation speed and direction to a predetermined value after that, safe and efficient powdering work can be performed.

In addition, in order to powder a substance with a high viscosity such as a resin, it is sufficient to operate at a low speed for a relatively long period of time and then increase the rotation speed to a specified value.

Alternatively, the rotational speed may be gradually increased in them.

As is clear from the above description, the mixer of the present invention consists of a rotating drum 2, a rotating frame 3, and an agitating shaft 4, and by rotating each independently, the relative speed of each can be increased. It has the effect of increasing the mixing speed and shearing and pulverizing the object to be powdered, and making it possible to mix safely and quickly by changing the rotation direction and speed of the rotating drum etc. depending on the object. .

Moreover, the presence of the partition plate of the rotary drum 2 allows vertical mixing, and the presence of the spiral barriers 18 and 19 allows the mixture to flow left and right and is stirred uniformly.

Furthermore, since the drum 2, frame 3, and stirring shaft 4 each have the same center of rotation, the mixer can have a large sealing effect with fewer sealing points of moving parts.
