Description

Recycled concrete product production device and production method that can be adjusted considering recycling rate and replacement rate {Recycled concrete production device and production method with recycling ratio}

The present invention relates to an apparatus and production method for producing recycled concrete products that can be adjusted by taking into account the recycling rate and replacement rate, which can supply new aggregate and recycled aggregate to match the recycling rate and replacement rate.

In the case of general concrete products, they are manufactured using aggregate collected from rocky mountains or rivers, but recycled concrete products are cement concrete manufactured by mixing recycled coarse aggregate and recycled fine aggregate with new coarse aggregate and fine aggregate, and then mixing them with water and cement. It means product. Recycled concrete products are produced by molding them into bricks, etc.

According to the Ministry of Land, Infrastructure and Transport’s “Recycled Aggregate Quality Regulations,” the amount of recycled aggregate used when manufacturing recycled concrete using recycled aggregate is calculated as a substitution ratio (%) based on volume [recycled aggregate volume / (new aggregate + recycled aggregate volume)]. As stipulated, if only coarse aggregate is used, recycled aggregate should be replaced by 60% or less of the total volume of coarse aggregate, and if only fine aggregate is used, recycled aggregate should be replaced by 30% or less of the total volume of fine aggregate. If coarse and fine aggregate are to be used simultaneously, the total amount used should be less than 60% of the total volume of fine aggregate. It is recommended to use less than 30% of the aggregate volume.

Meanwhile, concrete-related standard specifications manage concrete mixing by weight, and the recycling rate of recycled products (=weight of recycled aggregate/(weight of new aggregate + recycled aggregate)) is specified as a weight ratio.

Additionally, the water hopper 120 may have a hopper opening/closing portion 130 formed at its lower portion to accommodate a certain amount of water and then supply it to the mixed raw material. This material supply member 100 is configured to open and close the hopper opening and closing unit 130 by the aggregate dispensing control member 500 after a certain amount of new aggregate or recycled aggregate is received in the aggregate hopper 110 with the hopper opening and closing unit 130 sealed. When opened, the aggregates filled in the aggregate hopper 110 are discharged and supplied to the mixing member 300. Then, a certain amount of water is supplied to the mixing member 300 through the water hopper 120.

The height measuring member 200 measures the height of new aggregate and recycled aggregate accommodated inside the aggregate hopper 110. The height measuring member 200 may be one of an ultrasonic sensor, a laser sensor, and a radar sensor, or may be a scale formed on the inner surface of the aggregate hopper 110.

The stirring unit 320 includes a rotating shaft rotatably installed in the mixing tank 310 and stirring blades formed at regular intervals on the rotating shaft.

The rotating unit 330 may include a motor that rotates the rotating shaft of the mixing tank 310. Therefore, the stirring blade is rotated by the operation of the rotating part 330, making it possible to mix cement and aggregate with water to produce concrete.

The guide portion 340 is preferably located on the bottom of the mixing tank 310, but may also be formed on the side.

The weight measuring member 400 measures the weight of the new aggregate and recycled aggregate input from the mixing member 300 where the material is filled. The weight measuring member 400 is located at the bottom of the mixing tank 310, and it is preferable to use a load cell. In particular, when the blocking unit 350 is located below the mixing tank 310, the weight measuring member 400 is preferably formed at the rear of the blocking unit 350. When new aggregate or recycled aggregate is sequentially introduced into the mixing tank by this weight measuring member 400, each weight can be accurately confirmed using the weight difference.

As shown in FIG. 3, the aggregate dispensing control member 500 measures the height of the new aggregate and recycled aggregate received in the initial aggregate hopper 110 measured by the height measuring member 200 and the weight measured by the weight measuring member 400. Using the measured weight of the new aggregate and recycled aggregate, the height of the new aggregate and recycled aggregate to be additionally accommodated in the aggregate hopper 110 is calculated to match the recycling rate of the recycled aggregate. This aggregate administration control member 500 includes a recycling rate registration unit 502, a hopper opening/closing operation unit 504, an aggregate hopper volume confirmation unit 506, a standard height management unit 508, a standard aggregate weight confirmation unit 510, and an additional It includes an input aggregate weight confirmation unit 512, a hopper height confirmation unit for additional input aggregates 514, a replacement rate registration unit 516, and a replacement rate confirmation unit 518.

The recycling rate register 502 registers the recycling rate of the recycled aggregate mixed in the mixing tank. At this time, it is desirable for the recycling rate registration unit 502 to confirm that the recycling rate of the recycled aggregate being registered is within the replacement rate of the recycled aggregate.

The hopper opening/closing unit operating unit 504 controls the operation of the hopper opening/closing unit 130 that opens and closes the lower part of the aggregate hopper 110. When the hopper opening/closing unit 130 is sealed by the hopper opening/closing operation unit 504, new aggregate or recycled aggregate can be accommodated inside the aggregate hopper 110, and when the hopper opening/closing unit 130 is opened, new aggregate or recycled aggregate can be accommodated inside the aggregate hopper 110. Aggregates can be supplied to the mixing tank.

The aggregate hopper volume confirmation unit 506 stores or calculates volume information corresponding to the height of the aggregate hopper 110. When the height of the aggregate hopper 110 is confirmed by the aggregate hopper volume confirmation unit 506, the volume can be calculated, and when the volume is confirmed, the height of the aggregate hopper 110 can be calculated.

For example, the hopper height confirmation unit 514 for additionally input aggregate can check the volume of the aggregate hopper 110 for each height of the aggregate hopper 110, so it is possible to check the volume of the aggregate hopper 110 for new aggregate and recycled aggregate input at the standard height. Using the confirmed volume and weight, it is possible to calculate the volume of the aggregate hopper 110 corresponding to the confirmed weight of the additionally introduced new and recycled aggregate. In addition, the volume of the aggregate hopper 110 corresponding to the height of the aggregate hopper 110 is calculated in real time or stored in the hopper volume confirmation unit 506, so the volume corresponding to the volume of the aggregate hopper 110 is calculated in real time or stored in the hopper volume confirmation unit 506. Height can also be easily checked.

The replacement rate register 516 registers information about the replacement rate of the recycled aggregate mixed in the mixing tank. When only coarse aggregate is used, the replacement rate is registered as 60% or less of the volume of coarse aggregate, when only fine aggregate is used, it is registered as 30% or less of the volume of fine aggregate, and when coarse and fine aggregate are used simultaneously, the replacement rate is registered as total aggregate (new aggregate + It is desirable to register within 30% of the volume (recycled aggregate).

The replacement rate confirmation unit 518 checks whether the amounts of new aggregate and recycled aggregate confirmed in the additional input aggregate weight confirmation unit 512 and the amounts of standard new aggregate and recycled aggregate initially introduced are within the standard replacement rate. At this time, the replacement rate confirmation unit (518) If the replacement rate of recycled aggregate exceeds the standard replacement rate, the manager is notified.

Hereinafter, we will look at the work process of the recycled concrete product production device that can be adjusted in consideration of the recycling rate and replacement rate of the present invention.

First, with the hopper opening and closing portion 130 under the aggregate hopper 110 closed, new aggregate or recycled aggregate is accommodated to match the standard height, and the volume of the aggregate is checked. At this time, the height of the new aggregate or recycled aggregate accommodated in the aggregate hopper 110 is confirmed by measuring through the height measuring member 200, and the volume of the aggregate is calculated to correspond to the height of the aggregate hopper 110. use. The height measuring member 200 may use any one of an ultrasonic sensor, a laser sensor, and a radar sensor, or may use a scale formed on the inner surface of the aggregate hopper 110.

After the new aggregate or recycled aggregate is accommodated to match the standard height, the hopper opening/closing part 130 at the bottom of the aggregate hopper 110 is opened, and when the aggregate hopper 110 is dropped into the inside of the mixing container, the weight measuring member 400 located at the bottom of the mixing container is opened. Measure the weight of the mixing container. Accordingly, the weight measuring member 400 measures the weight of the mixing bucket containing the new aggregate when the new aggregate is first added, and when the recycled aggregate is additionally added, the weight of the mixing bucket containing the new aggregate and the recycled aggregate is measured. It will be measured.

The aggregate administration control member 500 uses the volume of the aggregate hopper 110 corresponding to the reference height as the volume of aggregate, and uses the cumulative weight of new aggregate or recycled aggregate measured by the weight measurement member 400 as the respective standard. Check with the input weight.

Additionally, the aggregate administration control member 500 checks the weight of the additionally added new aggregate and recycled aggregate to correspond to the previously registered recycling rate of the recycled aggregate. Since the aggregate administration control member 500 can check the weight of the initially introduced new aggregate and recycled aggregate, it is possible to simply check the weight of the new aggregate and recycled aggregate to match the recycling rate.

In addition, the aggregate administration control member 500 checks the volume of the additionally introduced new aggregate and recycled aggregate accommodated in the aggregate hopper 110 when the weight of the additionally added new aggregate and recycled aggregate is confirmed to match the recycling rate. do. For example, since the volume of the hopper 110 for the first input aggregate is used as the volume of new aggregate and recycled aggregate, the volume corresponding to the weight of the additional aggregate input compared to the volume and weight of the initially input aggregate is used. It becomes possible to calculate.

Additionally, when the volumes of new aggregate and recycled aggregate are confirmed, the aggregate dispensing control member 500 calculates the height of the aggregate hopper 110 corresponding to the volume.

When the heights of the new aggregate and recycled aggregate accommodated in the aggregate hopper 110 are calculated through this process, the new aggregate or recycled aggregate is placed at the corresponding height while the hopper opening and closing part 130 at the bottom of the aggregate hopper 110 is sealed. After receiving it to correspond to , the hopper opening/closing part 130 is opened and supplied into the mixing tank.
