Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a device and a detection method for realizing automatic detection of concrete test steel slag. Background Art

[0002] At present, there is no relevant automatic detection equipment for steel slag concrete on the market, and there is no perfect management method for concrete steel slag detection. At present, the magnetic attraction method is usually used. The technical principle of the magnetic attraction method is based on the presence of magnetic substances in steel slag. Magnetic separation equipment is used to magnetically separate aggregates. Once ferromagnetic substances are found on the magnetic separation equipment, it is considered that there is steel slag in the aggregate. This method has the advantages of being fast, non-destructive, and intuitive, but it requires manual operation, is not intelligent, and is time-consuming and labor-intensive. Therefore, there is an urgent need for a detection device and detection method that can automatically detect steel slag and push the detection data to relevant management personnel in a timely manner through the Internet of Things. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a device and a detection method for automatic detection of concrete slag, which can realize the automatic detection of concrete slag, and can realize the Internet of Things function through Modbus communication, and cooperate with an external server to realize remote control and real-time viewing of detection data.

[0004] The present invention achieves the above technical objectives through the following technical means.

[0005] A device for realizing automatic detection of concrete slag comprises a detection device and a PLC control system for comprehensively controlling the detection device. The detection device comprises a main frame and an upper hopper arranged on the main frame, a dilution and separation mechanism is arranged at a discharge port below the upper hopper, a baffle plate capable of moving up and down is installed on the dilution and separation mechanism, a liquid flow channel is arranged at the lower part of the dilution and separation mechanism in front of the baffle plate, and a vibrating hammer is installed at the lower part of the dilution and separation mechanism behind the baffle plate; the end of the dilution and separation mechanism is docked with an adsorption flow channel, and an electromagnet is installed above the docked adsorption flow channel; a waste collection box is installed below the end of the adsorption flow channel, and a slag collection channel with a weighing sensor is also installed at the end of the adsorption flow channel, and the weighing sensor is connected to the PLC control system signal; the slag collection channel is docked or separated with the adsorption flow channel through a cylinder.

[0006] Furthermore, a capacity detection system connected to the PLC control system signal is arranged in the loading hopper to determine whether the concrete loading is completed.

[0007] Furthermore, the bottom valve of the upper hopper is controlled by a PLC control system.

[0008] Furthermore, the PLC control system includes a human-computer interaction screen and a control button; the control button is used to input the human-computer interaction signal input through the human-computer interaction screen into the PLC, so as to realize manual control of the entire detection system when a failure occurs in the automatic operation of the detection system; the human-computer interaction screen is used to visually display the detection data.

[0009] A method for automatically detecting concrete slag using the above-mentioned device for automatically detecting concrete slag comprises the following process: Step 1: Press the start button of the PLC control system, the equipment starts, and concrete is poured into the upper hopper. After the capacity detection system in the upper hopper determines that the feeding is completed, it sends a signal to the PLC control system; Step 2: The PLC control system automatically controls the baffle plate to fall down and controls the valve at the bottom of the upper hopper to open; Step 3: Concrete falls from the upper hopper and enters the dilution and separation mechanism. At the same time, water is added above the upper hopper for dilution. Under the reciprocating motion of the dilution and separation mechanism, fine particles and water leak into the liquid flow channel below, and large-size particles are blocked by the baffle plate; Step 4: After the dilution and separation mechanism is completed, the PLC control system controls the material blocking plate to rise, and at the same time controls the vibration hammer to vibrate and energize the electromagnet, and the concrete enters the adsorption flow channel from the dilution and separation mechanism; Step 5: When the concrete passes through the adsorption flow channel, the steel slag is adsorbed and collected by the electromagnet; the concrete particles that are not adsorbed fall from the adsorption flow channel to the waste collection box below; Step 5: The PLC control system controls the cylinder to work and push the slag collection channel to connect with the adsorption channel; Step 6: After the docking is completed, the PLC control system cuts off the power to the electromagnet, and the slag falls down and enters the slag collection channel. The slag is weighed by the weighing sensor to obtain the slag quality data, which is then transmitted back to the PLC control system for data analysis and calculation. The slag content of the concrete is calculated based on the total amount of concrete, and the data is displayed on the human-computer interaction screen; Step 7: The PLC control system transmits all the equipment operation status information and detection data information to the industrial computer through Modbus communication according to the instructions issued by the host computer; Step 8: After the data is transmitted, the industrial computer divides the data according to the amount of concrete, time, and location, and adopts the authority management method to enable managers at all levels to remotely and accurately control the measurement data.

[0010] The present invention has the following beneficial effects: The present invention can be applied to the construction site to quickly and automatically detect whether there is steel slag mixed in the concrete. It can make up for the shortcomings of the traditional detection method that is complicated and slow, and can realize intelligent control of the equipment through PLC control logic, greatly improving the detection efficiency. At the same time, it has the function of Internet of Things, which can realize remote control and status monitoring of steel slag detection. The present invention uses an automatic magnetic suction device and an automatic weighing device to realize automatic detection of the steel slag content in concrete; at the same time, it uses modbus communication to realize data networking and remote data control. The automation of concrete steel slag detection is realized without manual participation, which solves the steel slag problem and quality control problem in the process of concrete entering the site.
