Many structures, such as bridges, roads, and various buildings, which have arisen in the process of industrialization, have become obsolete over time. As a result, dismantling, reconstruction and redevelopment of aged buildings are actively being carried out.

In the process of demolition, reconstruction or redevelopment of old structures, many construction wastes are generated. If such landfills are to be landfilled, landfill sites are difficult to obtain and landfill costs are high, which can seriously affect the environment. Accordingly, a variety of architectural waste disposal measures have been developed in terms of protection of the natural environment and recycling of resources.

If the amount of the raw material is greater than the reference amount, the feeding angle is lower than the reference angle. If the amount of the raw material is less than the reference amount, the feeding angle is increased to be higher than the reference angle.

In the step (d), if the amount of the input raw material is larger than the reference amount, the conveying speed is lower than the reference speed, and if the amount of the input raw material is less than the reference amount, the conveying speed is increased higher than the reference speed to increase the productivity.

The apparatus and method for separating recycled aggregate foreign materials from construction waste according to the present invention will be described in detail as follows.

First, when the construction waste is received in the hopper 101, the first crusher 102 impacts and crushes the construction waste aggregate contained in the hopper 101. In this case, when the construction waste aggregate is coarse aggregate for concrete, it is also possible to separate the sand attached to the coarse aggregate. Here, the first crusher 102 can be implemented with various crushers. For example, a crusher 102 such as a cone crusher or a jaw crusher may be used (S1, S2).

The aggregate crushed by the first crusher 102 becomes an aggregate material and is stored in the aggregate material repository 103 (S10).

Thereafter, the aggregate stored in the aggregate material reservoir 103 is crushed by the second crusher 104 (S20). Here, it is preferable that the second crusher 104 also use a crusher such as the impact crusher or the cone crusher.

The aggregates crushed by the crusher are screened by the first screen 114 and separated by the granularity (S30). The first screen 114 may utilize a vibrating screen device such as a saclping screen equipment.

Here, the first screen 114 selects the crushed aggregate from the first to fourth particle sizes. Here, it is preferable that the first particle size is less than 5 mm, the second particle size is less than 5 mm to 9 mm, the third particle size is less than 9 mm to 25 mm, and the fourth particle size is 25 mm or more.

The aggregate having the smallest grain size among the aggregates selected by the first screen 114, that is, the aggregate having the first grain size of less than 5 mm in size, is selected as the fine aggregate and accommodated in the fine aggregate storage. The residual aggregate contained in the residual aggregate storage is finally separated into waste and residual aggregate (sand) through the sand flux treatment to produce the aggregate aggregate (S40). Here, the sand flux device is a combination of the cyclone device 108 and the flux tank 116, and utilizes the specific gravity and buoyancy difference, and automatically discharges sand (aggregate aggregate) under the flux tank 116 by the pinch valve It is a technology to remove foreign substances contained in construction waste or dredged soil.

For example, with respect to the aggregate aggregate contained in the aggregate aggregate reservoir, the aggregate aggregate and the foreign matter are primarily separated through the cyclone equipment 108 (S41). Here, the cyclone device is a well-known device well known in the field of construction waste. A mixture of building waste and washing water is firstly separated from a light foreign matter having a specific gravity of 1.0 or less, which is mixed with construction waste by centrifugal force generated by swirling flow .

The foreign matter separated by the cyclone device is finally separated into sand and waste through the sand-flux tank 116 (S44). The separated garbage is discharged to the garbage dewatering screen 109 (S42). Here, the sand flux separates the waste from the residual aggregate using the buoyancy difference. That is, a mixture of water and washed sand (fine aggregate) is floated by a difference in specific gravity between the washed sand and foreign matter such as a piece of vinyl, wood or the like mixed with the washing sand by the buoyancy means by the water injection device in the tank 116, To remove foreign substances such as vinyl and wood chips.

In addition, the residual aggregate separated by the cyclone device 108 and the sand flux tank 116 is removed through the residual aggregate dewatering screen 110 to produce sand as a residual aggregate (S43, S44).

Next, the aggregate having the second granularity selected by the first screen 114 is again crushed through the second crusher 104, and then sorted again by the granularity through the first screen 114. The aggregate having the selected first particle size is treated through the sand flux treatment process and separated into garbage and sand.

The coarse aggregate having the third granularity and the fourth granularity selected by the first screen 114 is crushed by the third crusher 105 (S50). Here, the third crusher 105 preferably uses a crusher such as the impact crusher and the cone crusher.

The aggregate crushed by the third crusher 105 is screened through the second screen 115 and separated by the granularity (S60). The second screen 115 may utilize a vibrating screen device such as a saclping screen equipment.

Here, the second screen 115 also scrapes the crushed aggregate from the first size to the fourth size in the same manner as the first screen 114. Here, the first particle size is less than 5 mm, the second particle size is less than 5 mm to 9 mm, the third particle size is less than 9 mm to 25 mm, and the fourth particle size is set to 25 mm or more.

Aggregates having the smallest particle size among the aggregates selected by the second screen 115, that is, aggregates having the first particle size of less than 5 mm in size, are selected as the remaining aggregate and transferred to the sand flux processing apparatus to be accommodated in the aggregate aggregate storage. The residual aggregate contained in the aggregate reservoir is finally separated into waste and residual aggregate (sand) through sand flux treatment, resulting in the production of fine aggregate.

Next, the aggregate having the second granularity selected by the second screen 115 is again crushed through the first crusher 104, and then sorted again by the granularity through the first screen 114. The aggregate having the selected first particle size is treated through the sand flux treatment process and separated into garbage and sand.

The coarse aggregate having the fourth particle size selected by the second screen 115 is conveyed to the second crusher 105 to be crushed again and screening is performed through the second screen 115 And are sorted again by the first to fourth grain sizes. Thereafter, the coarse aggregate having the fourth grain size is repeatedly subjected to the crushing and screen screening process again.

Meanwhile, the coarse aggregate having the third particle size selected by the second screen 115 is separated into a foreign matter and a coarse aggregate through the circulating aggregate foreign material separator 117 (S70).

That is, the coarse aggregate having the third particle size is accommodated in the coarse aggregate reservoir, and then separated into the foreign matter and coarse aggregate by the circulating aggregate foreign matter separator 117, and the foreign matter is dehydrated by the dehydrating screen 106 , And the garbage is separated (S72, S73).

The recycled aggregate foreign matter separator 117 separates waste from the coarse aggregate using the specific gravity difference. That is, when a mixture of water and coarse aggregate is injected in the tangential direction in the apparatus, foreign substances (for example, vinyl, wood chips, etc.) mixed with the coarse aggregate float due to the difference in specific gravity, The trash is removed. The coarse aggregate from which the trash is removed is used as the coarse aggregate material.

The coarse aggregate separated and processed by the recycled aggregate foreign matter separating device 117 is subjected to dehydration screening by the aggregate dehydrating screen 107 and finally produced in coarse aggregate (S72).

At this time, as a feature of the present invention, it is possible to automatically adjust the flow rate of the washing water, the aggregate conveying angle and the aggregate conveying speed according to the state (input amount and shape) of the raw material (coarse aggregate) .

For example, as shown in Fig. 2, the raw material state detecting means 201 detects the state of the input raw material. Here, it is preferable to detect the amount of the charged raw material and the shape of the raw material. Preferably, the amount of the charged raw material is detected by using the raw material supply amount information or by measuring the weight, and the shape of the raw material is preferably photographed and the shape of the raw material is detected through image analysis. The shape of the raw material means a shape such as a quadrangle, a circle, an ellipse, or a triangle. It is preferable that the shape of the raw material is detected by photographing the raw material, separating the object from the photographed image, and extracting the outline of the separated object.

The state values of the detected raw materials (input raw material amount and raw material shape information) are transmitted to the control means 202. The control means 202 generates a wash water speed control signal and an aggregate transfer angle control signal based on the state of the input raw material detected by the raw material state detection means 201.

That is, if the amount of the input raw material is less than the reference amount, the control means 202 lowers the flow rate of the wash water to a level lower than the reference level, and if the amount of the raw material is greater than the reference amount, Increase cleaning power.

When the amount of the raw material is greater than the reference amount, the control means 202 lowers the conveying angle lower than the reference angle. If the amount of the raw material is less than the reference amount, the controlling means 202 generates an aggregate conveying angle control signal, .

If the amount of the input raw material is larger than the reference amount, the control means 202 lowers the conveying speed lower than the reference speed. If the amount of the input raw material is less than the reference amount, the conveying speed is increased to be higher than the reference speed.

On the other hand, according to the washing water speed control signal, the washing water speed adjusting unit 203 adjusts the speed of the washing water flowing in the aggregate dewatering screen 107. The flow rate of the washing water can be controlled by using a pump for supplying wash water or by using any known apparatus capable of controlling the flow rate.

The aggregate conveyance angle adjusting unit 204 adjusts the angle of the aggregate conveyance conveyor belt 301 provided on the aggregate dewatering screen 107 in accordance with the aggregate conveyance angle control signal generated by the control unit 202, . The aggregate conveying angle is preferably adjusted by adjusting the height of the conveyor belt to adjust the conveying angle. Particularly, by controlling the feeding angle of the aggregate according to the shape of the raw material, the aggregate conveyance angle is inclined so that the conveyed aggregate can be prevented from flowing down when the aggregate has a circular shape or the like.

For example, as shown in FIG. 3, the circulating aggregate foreign matter separating apparatus 117 adjusts the angle of the conveyor belt 301 for conveying the aggregate through the cylinder 302. Here, a plurality of cylinders 302 for adjusting the height of the conveyor belt 301 are provided below the conveyor belt 301, and the plurality of cylinders are individually controlled to adjust the angle.

The recycled aggregate foreign matter separator 117 receives washing water for washing the foreign matter adhered to the aggregate, and the foreign matter floats on the water surface. At this time, if the entire conveyor belt is adjusted, the conveyor belt may float on the water surface, which may adversely affect the filtering of the foreign matter. Therefore, in the present invention, the conveyor belt flotation prevention part 303 is provided at the middle part of the conveyor belt among the whole conveyor belts so that the conveyor belt is pressed downward or the left and right sides of the conveyor belt are guided downward, Avoid injury.

The aggregate conveying speed adjusting unit 205 adjusts the conveying speed of the aggregate conveying belt 301 by using the motor 304 provided in the circulating aggregate foreign matter separator 117 in accordance with the aggregate conveying speed control signal generated by the control unit 202, To control the moving speed of the aggregate. If the amount of the input raw material is larger than the reference value, it is preferable to lower the aggregate conveying speed. If the amount of the input raw material is less than the reference value, it is preferable to increase the aggregate conveying speed.

Here, the present invention automatically adjusts the flow rate of the washing water, the conveyor feeding angle and the conveyer feeding speed individually according to the amount and shape of the charged raw material (coarse aggregate). Here, the control of the flow of the washing water and the adjustment of the aggregate conveying angle control the washing force, and the conveying speed of the conveyor belt controls the productivity.

The screen device 300 interlocks with the washing water speed adjusting unit and the aggregate conveying angle adjusting unit to remove foreign matter adhered to the aggregate. Such a circulating aggregate foreign matter separating apparatus means the circulating aggregate foreign matter separating apparatus 117 of FIG.

Meanwhile, in the construction waste disposal system of the present invention, the sludge having passed through the waste dewatering screen 109 is precipitated and concentrated through the sludge processor 112. The treated sludge is stored in the sludge tank 113.

The sludge processor 112 may be a sludge processor, a sludge processor, a sludge tank, a sludge tank, a sludge tank, a sludge tank, And a pump for selectively supplying the sludge to the filter press, depending on the concentration of the sludge, which is located below the storage tank and includes a pump for supplying the sludge to the filter press . Such a sludge processor is also a well-known technology well known in the field of construction waste disposal, and a detailed description thereof will be omitted.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.
