Description

Detailed Description of the Invention (Industrial Application Field) The present invention is applicable to a method for treating industrial waste such as sludge from factory wastewater, ore sand from the foundry manufacturing process, and general waste such as cinders from local governments. Pause.

(Prior Art) Regarding the above-mentioned industrial and general waste treatment methods, certain treatment standards have been established by the "Waste Disposal Law," and efforts are being made to preserve the living environment and maintain public health.

However, given the current situation where a huge amount of diverse waste is being generated and the construction of a new treatment plant is strongly opposed by local residents, the treatment system has not been able to keep up with this, and the lack of treatment capacity has become chronic. I am in a situation where I am.

For this reason, there are countless examples of illegal dumping in mountains, gravel pits, etc. However, when illegal dumping occurs in this way, toxic substances permeate deep into the ground along with rainwater and enter the groundwater. This poses a serious problem in that it causes harm to the health and living environment of the general population.

(The invention attempts to solve the problem! The main aim is to eliminate the above-mentioned problems by applying appropriate solidification treatment to waste by utilizing its properties, and successfully obtaining useful materials for gateposts, paving blocks, etc.

(Means for Solving the Problems) In this method of manufacturing gateposts, etc. using waste, first, wastes such as powdered slag, sludge, cinders, etc. are collected and mixed in a mixer or the like. Then, 10% or more of hot-melt synthetic resin waste is added to the mixture, melted and kneaded under heating, and then put into a mold of a certain shape and allowed to cool and harden to form a core part.

Next, powdered or granular marble,
A kneaded mixture of decorative stones such as granite and bricks mixed with polyester resin is molded into surface members to form molded products such as gateposts and paving stone blocks that are made of marble, granite, bricks, etc. It is structured with the characteristic of obtaining.

(Function) Heat-melting synthetic resin waste melts powdered slag, sludge, cinders, etc. by heating and exhibits caking properties, bonding the wastes together and eliminating the need for other hardening agents. The waste itself acts to form a core of a certain shape.

In addition, the powdered or granular marble and the surface material in the polyester resin not only cover up this core material but also reveal the processing of the marble, forming beautifully decorated gateposts, paving stone blocks, etc. work.

Additionally, this polyester resin is resistant to ultraviolet rays and improves weather resistance.

(Results) The present invention based on the above configuration can assimilate waste materials such as mine slag, sludge, and cinders that were conventionally disposed of, so a hugely large treatment plant for disposal is not required. This will be an important means of solving the problem of waste disposal, which has been suffering from a chronic lack of capacity. And huge i! a* *
The economic benefits are extremely large compared to conventional treatment methods for controlled waste that requires use.

At this time, since the heat-melting property of the waste synthetic resin such as polyethylene was used for caking, the waste itself can be solidified, which is economical since no curing agent or the like is required.

Furthermore, since waste is actively used to make useful materials such as gateposts, the recycling process becomes flexible, leading to the effective use of natural resources, and it also has a decorative effect by processing marble, granite, etc. Because it is a product, it is possible to obtain products with high added value.

(Example) 400 kg of dehydrated sludge from a cannery and I! 200 kg of slag from a steel factory and 10 husk of construction waste from local government
Then, 100 kg of polyethylene, 100 kg of nylon, and 100 kg of polystyrene were crushed into 5 x 5 x 5 mm pellets using a crusher, and mixed in a mixer for about 5 minutes.Next, this mixture was extruded using a heating device. The mixture was put into a machine and kneaded while being heated to about 200°C. Then, while the resin content melts, sludge,
It mixed with the waste from the slag and became homogenized. Then, this was filled into a 30 x 30 x 140 cm prismatic molding frame, pressed from above with a hydraulic press to increase density, and then left in a dry chamber for 24 hours. As a result, as the resin was cooled, the uniformly mixed resin bonded the waste materials and solidified, yielding a core material portion with considerable strength.

Next, a board of pre-hardened powdered marble was laid under this core material, and a molded frame shaped like a gatepost was placed around it.
A kneaded mixture of powdered marble and polyester in a ratio of 9:1 was filled into the container while removing air using a vibrader, and the mixture was left to stand for 30 minutes to cure and harden to obtain a surface member.

After the assimilation was completed, the surface was polished with sound vapor, and the marble treatment was revealed, resulting in a beautifully decorated gatepost.

(Example 2) 350 kg of slag from an aluminum field and 50 kg of polyethylene
kg, 50 kg of nylon, and 50 kg of polystyrene were crushed into pellets of 5 x 5 x 5 nm using a crusher, and mixed in a mixer for about 5 minutes.Next, this mixture was put into an extruder with a heating H setting, and the pellets were crushed into pellets of about 5 x 5 x 5 nm. 200
When kneaded while heating to ℃, the resin content melted and mixed with the slag waste to homogenize it. And this is 30x
It was filled into a 30 x 5 cm square road paving stone block molding frame, pressed from above with a hydraulic press to increase the density, left in a dry room for 24 hours, and allowed to cool until the uniformly mixed resin content was mixed. The wastes were combined and solidified.

Next, the surface of this paving stone block was filled with a kneaded mixture of powdered granite and polyester in a ratio of 9:1 while removing air with a vibrator, and cured and solidified to a thickness of 5 mm.
The surface layer had a thickness of .

As a result, the geometric patterns engraved on the molding frame appeared and a beautiful paving stone block was obtained.
