Description

Detailed Description of the Invention This invention cuts old tires and other combustible waste, mixes it with papermaking sludge that has a high calorific value, kneads it, compresses it, dehydrates it, shapes it, and incinerates it as solid fuel. This invention relates to an invention that achieves the two purposes of processing polluted waste and securing thermal energy by effectively utilizing the amount of heat obtained by doing so.

Conventionally, papermaking sludge containing a large amount of water has been incinerated using a large amount of expensive combustion oil.

Therefore, a large amount of money was required to incinerate it.

In addition, this papermaking sludge is disposed of in large quantities by each papermaking factory, so the current situation is that it cannot be burned in time and is piled up in the open.

When this sludge is piled up in the open, the chemical water contained in the sludge flows into the river and causes pollution, and it also has a negative impact on hygiene, and a large amount of used tires and other waste are disposed of. The only way to deal with it was to spend a lot of money and wastefully burn it.

This waste, which has become a social problem, is turned into solid fuel and burned, and the resulting heat is effectively used for power generation, agriculture, industry, or leisure. Most of the chemicals contained in the liquid are compressed and dehydrated together with moisture to form a solid body, and the solid form is formed in a state in which almost no moisture is present.

Therefore, it is easy to store and organize large quantities as fuel, and it is also meaningful from a sanitary standpoint.

Next, an embodiment of the device of the present invention will be explained with reference to the drawings.
The embodiment shown in the figure and the embodiment shown in FIG. 2 have the same purpose but differ in compression molding means, and their effects are exactly the same.

Therefore, common drawing symbols are used for the same parts of the device.

First, the embodiment shown in FIG. 1 will be explained.

The device shown in this example is of a type that performs dehydration molding by compression of a mold piston that is divided into left and right halves.
The vibration isolating rubber 3 is provided to prevent unnecessary vibrations from being transmitted to each device, and the durability of the entire device can be maintained for a long time.

is the provision.

4/ is a vibration table with a molded cylinder attached.

10 is a motor for a vibrator, 11 is a vibrator, and 12 is a rubber plate for hopper vibration isolation, which is an isolation buffer that prevents the vibration of the molding cylinder from being transmitted to the hopper 13.

Reference numeral 13 denotes a hopper in which a mixture of combustible waste such as cut old tires and paper sludge is stored.

A material stirring blade 18 is housed in the lower part of the hopper and is linked to a motor.

Reference numeral 15 denotes a drop guide plate for the molded solid fuel, by which the molded product 17 is guided and falls onto the transport conveyor 16 below.

To explain the operating process of this device step by step, first, paper sludge and cut pieces of waste (used tires and combustible waste thereof) are kneaded in a mixer.

During molding, the lower opening of the hopper 13 is closed by the high-pressure piston 5 and the hopper gate plate 9 fixed thereto by the forward movement of the high-pressure cylinder 8.

At this time, the low pressure cylinder 8/ moves forward and the low pressure piston 5/
/ has also advanced to the edge of the opening below the hopper.

Here, the molding material kneaded by the mixer is dropped from the hopper 13, and the stirring blades 18 are rotated to prevent moisture separation of the mixed material and supply the material in a constant state to the molding cylinder 4.

As the high-pressure cylinder retreats, the mold piston also retreats to its regular position.
The lower gate plate of the hopper is also released, and the molding material is dropped and supplied to the openings of the high-pressure piston 5 and low-pressure piston 51 in the molding cylinder 4.

Next, as the high-pressure cylinder 8 moves forward, the vibrator 11 also activates the motor 10, which vibrates the molding cylinder 4 via the diaphragm 4', and the molding material is vibrated and compressed between the high-pressure piston 5 and the low-pressure piston 51. Due to this squeezing pressure, water is squeezed out through the dehydration hole 7 of the mold piston and the dehydration hole 14 of the forming cylinder, and the pressure in the low pressure cylinder 8' moves while pressing the material by pressing with the high pressure cylinder 8, and the water is transferred to the high pressure cylinder. When the pressure of 8 becomes superior, the pressure of the low pressure cylinder 8/ is switched to the backward pressure by the switching valve, and the low pressure piston retreats to the fixed position, while the high pressure cylinder 8 continues to move forward, pushing the molded product forward. The high-pressure cylinder 8 is dropped onto the conveyor 16, and the high-pressure piston returns to its original position.

At the same time as this piston retreats, the low-pressure cylinder advances to advance the low-pressure piston to the hopper opening end, while the high-pressure piston 8 retreats, opening the hopper gate plate 9 and allowing the next molding material to fall and be supplied to the molding cylinder. .

The above-mentioned processes are sequentially and automatically controlled and operated repeatedly, and the waste is efficiently molded unattended to form solid fuel with almost no moisture remaining. There is no need for drying equipment.

Next, another embodiment shown in FIG. 2 will be described.
