Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for simultaneously measuring unit mass and production of aggregate, and a method for producing recycled aggregate using the unit mass and method.

The present invention relates to a device for simultaneously measuring unit mass and production of aggregate, and a method for producing recycled aggregate using the same. More specifically, the present invention can simultaneously measure unit mass and production amount of aggregate, It can be applied to all production of rocky aggregate using gemstones, and it is possible to evaluate the unit volume mass of the final product produced by analyzing the unit volume mass and the production amount for each lot. As a result, It is possible to produce final aggregate with quality that meets specification standard by storing mass as separate batch and determining batch mass per unit volume by batch production and unit volume mass measurement, The quality of the construction waste can be greatly improved and the recycling rate of the construction waste The unit volume weight of the invention to increase aggregate production and simultaneous measuring apparatus and a method of production using the same recycled aggregate.

In this case, the unit volume mass is a value obtained by dividing the mass of the recycled aggregate by the volume of the filled container, and includes the water content of the natural state read from the measuring apparatus installed on the site. The dry mass unit volume is obtained by drying the recycled aggregate in an oven And the measured value is filled.

Where G: mass of recycled aggregate (Kg)

       V: Volume of the container (L)

The unit mass of recycled aggregate varies depending on quality characteristics such as absolute dry density, particle size and porosity of the aggregate, so that the recycled aggregate having a high unit volume is excellent in quality.

In addition, the production amount per lot is obtained by obtaining the production amount (w) per hour of the aggregate filling the unit volume mass measurement container by using the time (t) to fill the unit volume mass measurement container and the mass volume of the initial setting unit, (W = w / t × T) can be obtained by taking lot (T) into consideration. By applying the weighted average method using lot volume and lot volume per unit volume, Can be determined.

Construction of various construction and civil engineering works Industrial wastes have increased sharply, mainly due to aging of buildings and urban buildings, revitalization of reconstruction, dismantling of structures, and so on.

Generally, the term "construction waste" refers to soil, sand, gravel, earth or sand mixed with waste materials, waste materials, etc., concrete blocks, waste wood, asphalt concrete blocks and construction sludge, One of the main characteristics is that most of the construction wastes are made of inorganic materials and are harmless to the human body and that they are discharged in a mixed state of various wastes and are complicated and difficult to handle. It provides the cause of government and industry indifference about waste disposal.

The above indifference has been accompanied by a waste of valuable resources, which has led to deterioration of the quality of the recycled aggregate, and the utilization of such recycled aggregate has been mostly used as substitute for the soil, such as the embankment, the soil and the landfill.

Therefore, it is necessary to actively promote minimization of environmental pollution, replacement of scarce resources, and cost reduction in the whole construction industry by enabling practical recycling through management of such waste.

According to the statistics of the Ministry of Environment in 2006, the annual amount of construction waste in Korea is 61.8 million tons / year, and its recycling rate is 97%, which is relatively high. However, due to limitations in processing technology and recycling field, There is a low problem.

The construction industry, which accounts for the largest amount of construction waste, is construction waste, which accounts for about 79% of the construction waste. However, mixed waste of various types and characteristics is mixed in construction waste, and mixed waste The recycled aggregate is produced as a single continuous process without taking into consideration the characteristics of the imported waste, so that it is difficult to obtain homogeneous quality and efficient treatment can not be achieved.

However, the intermediate treatment of construction waste mainly consists of crushing by crusher, screening by wind force, magnetic force and manpower, and equipment for removing foreign matters such as cement paste has been developed and applied. However, There is a problem in that it is not possible to produce a uniform quality recycled aggregate because the quality control is not implemented.

Therefore, it is necessary to develop recycling aggregate production technology using screening technology of recycled aggregate considering the characteristics of construction waste materials and recycling aggregate production technology using this technology. That is, countermeasure technology is needed to enhance the processing technology of construction waste and recycle it for optimum use It is true.

The applicant of the present invention has developed a construction waste sorting apparatus using a unit volume mass and a recycling aggregate production method using the unit volume mass as a solution to solve the above problems and presented it as a domestic patent application 10-2017-0099681 have.

In the construction waste sorting apparatus using the unit volume mass and the recycle aggregate production method using the same, the construction waste is sequentially crushed through the jaw crusher, the double jaw crusher, the cone crusher and the impact crusher in a natural state, (Ie, a device capable of conveniently and accurately measuring the unit volume mass of recycled aggregate in the course of producing recycled aggregate by processing construction waste), and then comparing the unit volume mass with the reference value If the unit volume mass of the construction waste measured by each lot is equal to or greater than the reference value, it is directly applied to the recycled aggregate. If the unit volume mass is less than the reference value, it is sent again to the impact crusher, which is the lowermost crusher, and the unit volume mass is measured again .

That is, the unit volume mass of the recycled aggregate is measured, and the recycled aggregate material quality is improved through the method of producing the recycled aggregate as it is according to the specified value, and conveying the rejected aggregate to the recycled aggregate.

However, in the case of selecting the construction waste using only the unit mass of the aggregate and using the same as the recycled aggregate, the recycled aggregate having higher quality than that of the standard is produced when the succeeding products are continuously produced, resulting in lowering the economical efficiency .

On the contrary, if the rejected products are continuous, the amount of the lower crusher is increased and the capacity of the lower crusher becomes insufficient. As a result, the operation of the equipment is stopped and production becomes impossible.

In addition, the unit volume mass per measurement lot can be evaluated, but the unit volume mass of the final product can not be known, so that the quality of the final product may fail.

In the production of recycled aggregate, it is possible to apply the re-crushing method because of the severe quality fluctuation of the waste. However, when the crusher aggregate is applied to the production of the rocky aggregate, It is difficult to apply this method.

3, the control panel 18 includes a key input unit 181 that allows an operator to arbitrarily set an initial unit mass W and a unit mass mass measurement interval T in units of minutes according to the characteristics of the aggregate A driving circuit of various cylinders, and the like, and controls the above-mentioned components through the execution of a control program determined in a state in which they are installed on the upper surface of the support table 6, The unit volume mass is evaluated, and the unit volume mass of the batch is determined to perform the overall control function necessary for the production of the recycled aggregate.

As shown in FIG. 4, a recycling aggregate production method using an apparatus for simultaneously measuring a unit mass and an output of an aggregate to which the present invention is applied comprises the steps of: The initial unit mass W and the unit mass mass measurement interval T determined in accordance with the property of the aggregate are input to the control panel 18 and the volume value of the unit volume mass measurement container 9 .

The initial unit volume mass W is a value obtained when the aggregate filled in the unit volume mass measurement vessel 9 is sub-filled in the upper portion of the unit mass volume measurement vessel 9, For example, it is preferable to set the mass value to be 10 to 20% larger.

When the input of various masses and time is completed, the control panel 18 drives the aggregate supply conveyor 5 to sequentially move the jaw crusher 1 through the double jaw crusher 2 and the cone crusher 3 After the crushing, the aggregate containing the construction waste conveyed through the aggregate supply conveyor 5 is continuously supplied to the small hopper 7 side.

Thereafter, the container transporting cylinder 10 is operated so that the unit volume mass measurement container 9 is moved to the small hopper 7 as shown in Fig. 1 for every predetermined unit volume mass measurement time T set in the control panel 18, Supporting rail 64 so as to be placed on the upper surface of the first load cell 11 so that the total amount of the aggregate discharged from the small hopper 7 is smaller than the unit volume So as to be filled in the mass measurement container 9.

In the production time measuring device 16 in which the aggregate discharged from the small hopper 7 is filled in the unit volume mass measurement container 9 as described above, the aggregate charging start time t1 is detected and transmitted to the control panel 18, And the control panel 18 stores it in a storage device provided therein.

While the unit volume mass measuring container 9 is filled with the circulating aggregate for measuring the mass volume in this way, the control panel 18 controls the first load cell 11 (see FIG. 1) supporting the bottom surface of the unit volume mass measuring container 9, The total mass of the recycled aggregate change amount currently filled in the unit mass measurement container 9 is input in real time through the unit volume mass measurement container 9 and the total weight change value for the recycle aggregate 9, The unit volume mass (D = the mass of the recycled aggregate (G; Kg) / the volume of the vessel (V; L)) is continuously calculated and it is continuously judged whether the changed unit volume mass equals the predetermined initial unit mass volume.

In this way, the output signal of the first load cell 11 is received in real time while the circulating aggregate is filled in the unit volume mass measurement container 9, and the output of the first load cell 11 is calculated in real time with respect to the total weight change value for the unit volume mass measurement container 9 and the recycled aggregate The control unit 18 recognizes that a desired amount of the recycled aggregate is filled in the unit volume mass measurement container 9 and the production time measuring device 16 recognizes that the desired amount of the recycled aggregate is filled in the unit volume mass measurement container 9, (T2) from the moment the aggregate flows into the unit volume mass measurement container 9 to the moment the aggregate returns to the unit volume mass measurement container 9 is detected and transmitted to and stored in the control panel 18, So that the unit volume mass measurement container 9 is transported along the upper surface of the container movement support rail 64 to the outside of the small hopper 7 as shown in FIG.

At this time, when the unit volume mass measurement container 9 is transported to the outside of the small hopper 7 along the upper surface of the container movement support rail 64 in correspondence with the operation direction of the container transport cylinder 10, A part of the circulating aggregate accumulated up to the upper surface of the unit volume mass measurement container 9 is flattened by the action of the horizontal surface forming member 8 provided at one side of the bottom of the hopper 7, Is in a plane state coinciding with the upper surface of the unit volume mass measurement container 9 in the vertical direction.

When the unit volume mass measurement container 9 is moved outward by a predetermined distance from the small hopper 7 while the upper surface of the recycled aggregate is flattened as described above, And has a shape raised on the upper surface of the base plate 12.

When the unit volume mass measurement container 9 is mounted on the upper surface of the second load cell 12 as described above, the control unit 18 includes the unit volume mass measurement container 9 through the second load cell 12, The total weight of the recycled aggregate filled in the inner space is measured and the unit mass of the aggregate is determined and transmitted to the control panel 18 and stored.

Thereafter, an initial unit volume mass W and an aggregate inflow starting time t1 detected by the control unit 18 through the production time measurement unit 16 are measured by the small volume hopper (T2-t1) XT} by comparing the time t2 and the unit mass measurement interval T, which have elapsed from the time t1 to the time t1, And the yield (S1) of the supplied aggregate to one lot is calculated.

In addition, the control panel 18 calculates the unit volume mass W1 using the weight of the aggregate measured through the second load cell 12, and then calculates the unit volume mass W1 using the production amount S1 measured for each lot, The volume mass W1 is substituted into the predetermined formulas (Eq. 2 and Eq. 3), and the unit volume mass for one batch and the production amount per day and the daily production amount are calculated.

That is, in the control panel 18, the unit volume mass of the batch calculated with a predetermined unit volume mass measurement interval T is expressed as "{volume per 1 lot volume * (volume of one lot / volume of one batch) + (Production volume of 2 lots / volume of production per batch (%)} + ... ... ... "and the yield per batch is calculated as" 1 lot production + 2 lot production + ... ... ... ", and the daily production amount is calculated by adding the production amount per batch produced during the day.

On the other hand, after the unit volume weight W1 for one lot is calculated in the control panel 18, the number of the lots N stored in the self-contained storage device is increased by "1" When the predetermined unit volume mass measurement time is set, the container transfer cylinder 10 is operated so that the unit volume mass measurement container 9 is moved to the bottom of the small hopper 7 and the top of the first load cell 11 It is returned to the step of transporting along the upper surface of the support rail 64, and the subsequent steps are repeated.

In addition, when a day's work is completed, the control panel 18 stores the aggregates in a batch on the basis of the daily production amount, and analyzes the production volume and unit volume mass of each lot to determine the unit volume mass of the batch, To provide the operator with the ability to produce final aggregate of quality satisfying the specifications.

At this time, the setting of the initial unit volume mass and the unit volume mass measurement interval (unit: minute) is set so that the preset value is lowered or increased to a desired value when the characteristics of the building waste or the rocky aggregate are changed You can reset it.

As described above, in the present invention, the rocky aggregate materials including the construction waste are sequentially crushed through a jaw crusher, a double jaw crusher and a cone crusher in a natural state, and then the unit volume mass is measured for each lot by a unit volume mass measuring device, Can be applied to both the production of recycled aggregate using construction waste and the production of rocky aggregate using gemstones by simultaneously measuring the production amount by measuring the time of filling the unit volume mass measurement container.

Also, by analyzing the unit volume mass and the production volume for each lot, it is possible to evaluate the unit volume mass of the final product produced, and the aggregate is produced by each lot based on a certain amount as in the case of daily production, It is possible to produce final aggregate with quality that meets specification standards by determining unit mass of batch by measuring production volume and unit volume mass, and in particular, by improving the quality of recycled aggregate, The recycling rate can be greatly increased.
