Description

[Detailed Description of the Invention] The present invention relates to gas pipeline construction, L sewerage] [1), electricity 1:
This is intended to be used as a recycling processing device for road waste materials generated as a result of the construction of elementary schools, etc. Abandoned roads are waste materials generated from the replacement of asphalt and concrete pavements, etc., and mainly consist of pavement waste materials, but may also include roadbed materials to some extent (hereinafter referred to as Ask 21 waste materials), and gas pipe waste materials. Waste materials generated from construction work involved in burying road-occupying objects such as
Most of the waste is roughly divided into 1 unit of roadbed, 1111 pavement waste, and waste including roadbed material (hereinafter referred to as excavation waste).

'4AJ is designed to recycle the ascon main body waste material and the excavated body waste material in one device, and the detailed description of the figure is as follows.

In No. 11.4, A indicates the excavated soil system, B indicates the ascon system, and C indicates the excavated ascon common system. The present invention basically consists of this lineage. First, the excavation system A starts from the excavation main body introduction part 1 to the first grizzly 2.
It consists of a system that passes through the bottom to the crushing and mixing device 3, and a system that runs from above the first grizzly 2 to the ascon main body introduction section 4. 2'1-, the common system C for excavation ascon consists of a system connected to the crushing mixer 3 described in FxIJ via It consists of a configuration in which a classification device 6 is connected to the crushing and mixing device 3 via a crushing device 7. Excavation L Ascon common system C is Excavation F
In order to process raw materials with widely different properties and processing methods, such as 1-piece waste material and 7-ascon material waste materials, it is desirable that the equipment used in the system be as follows.

First, the crushing mixer 3 is required to have both functions of mixing on excavation and crushing ascon. Regarding excavation, the primary purpose is to mix the 6J1 stabilizing material and the recovery aid, and there is no problem such as adhesion and growth even with high quality or viscous water, and at the same time, it is possible to crush ascon. The roll crusher is terrible. Further, the mixing device 5 is mainly used for crushing (tokigoshi) and secondary mixing of two lumps when processing excavated areas, and mainly uses E lumps of viscosity 1- that do not break even after passing through the crushing and mixing device 3. The ability to crush the materials and sufficiently disperse the stabilizer is required. An impact-type crushing mixer is desirable because this process can be carried out without trouble on sticky ILs and can also be used for crushing ascon.

Shichirokuda, crushing equipment'l 7 is required to have the function of crushing sieve-L materials when processing excavated areas, and has a large stone content, so suitable crushing equipment such as a crusher with a grinding plate is required. All you have to do is select. Furthermore, the classification system 6 connected to the common system C is composed of, for example, a photographic sieve, and there are various combinations depending on the improvement of the product and the particle size (particle size distribution) of the recycled aggregate. Improved particle size of...0 to 13 mn, recycled aggregate I...0 to 5 mn, t'-5 to 13 mn,
An example of the combination when the bar is 13 to 20 wm is shown in FIG. Note that when producing recycled aggregate, it may be better not to pass it through the mixing device 5 depending on the particle size, but in this case, it may be better to pass it through the bypass 8 and introduce it directly from the crushing mixer 3 into the classification system 6. Bye.

In the above-L configuration, when processing the excavation-based waste material, use the excavation system A and the excavated soil ascon common system C to obtain an improved surface, and when processing the ascon-based waste material, Recycled aggregate and recycled roadbed material are obtained using Ascon System B and Excavation L Ascon Common System C. First, regarding the treatment of excavated soil, the excavated raw material L -fE
71; Most of the waste material is roadbed material, and pavement waste material and roadbed material are being destroyed.

When this excavation f-m waste material is introduced into the first grizzly 2 through the excavation ■-introduction part 1, the ascon large lump 9 is sorted into the system to the ascon introduction part 4, and at the same time, the first grizzly 2
The excavated material and roadbed material will be collected in the raw material hopper 10 located in the F section of the site. This is cut out in a stationary manner by a stationary feeder 11, a certain amount of stabilizer is added from a stabilizing ladle supply section 12 along the way, and is supplied to the crushing and mixing device 3 together with a recovery aid described later. In the crushing and mixing system [13, stabilizers and recovery aids are first classified. As mentioned above, the classification system 6 is composed of a vibrating sieve, and the sieved material becomes product improvement 1-. .Sieve F consists of stones such as roadbed material as 13,
This is crushed into small pieces by a crushing device 7 and sent to a crushing and mixing device 3 as a recovery aid. L! :! Since it is made by finely crushing recovered auxiliary stone and has a low moisture content and is in the form of aggregated granules, it is possible to reduce the moisture content of the raw material supplied to the crushing and mixing device 3, which increases the bearing capacity of the product improved soil. In addition to increasing this, it also has the effect of reducing the adhesion of the raw material in the crushing and mixing device 3 and facilitating handling in the device 3 and beyond. Furthermore, since the same supporting force can be obtained with a smaller amount of stabilizer than when no recovery aid is used, there is an excellent effect of reducing the cost of improvement.

Next, Ascon 1: Explaining the treatment of body waste materials.
The Ascon L-body waste material used as a raw material is mainly composed of asphalt concrete pavement material and contains a certain amount of roadbed material. When such ascon-based waste material (of course, this ascon-based waste material also includes large ascon blocks 9 that have been sorted during excavation processing) is supplied to the second grizzly 2' through the ascon introduction section 4. As shown in the figure, a recycled roadbed material was obtained as a Grino II 7 layer. Grizzly 2'I- consists of asphalt concrete pavement material, which is sent to the crushing mixer @ 3 and subjected to primary crushing.
Next, the particles are sent to a mixing device 5 where they are subjected to secondary crushing and have a particle size range of
For example, recycled aggregate is classified into areas A, C and A in the figure. In classification system 6, sieved materials (-1 class frame '+ti,
1, which is finely crushed in step 7 and introduced into a crushing mixing device 3;
In this case, depending on the particle size in step 9), there are cases where the particles are passed through the mixing device 5, and cases where the particles are passed through the bypass 8 without passing through the mixing device 5. In either case, the particles are sent to the classifier 6 and classified into A, C, and C to obtain a product with the desired particle size (1).

The sieved material from the classifier 6 is finely crushed by the crusher 7 and sent to the crusher/mixer/ffi 3.

This project specifies the drilling system, ascon thread f, as follows.
A configuration is adopted in which friends are organically combined with the common system consisting of dr, excavation L ascon, and the common system is excavation f,
It is constructed so that it can be used in exactly the same way for both waste wood and Ascon 1 body waste, and moreover, it is designed to make the most of the monthly characteristics of the products and the treatment of both waste materials.
