[0002] During the construction process, construction sites will inevitably produce a large amount of waste slag. Due to its low density and large porosity, this type of soil can no longer be directly used in engineering construction and can only be taken away for treatment as engineering waste. This process is not only costly but also has certain harm to the environment and is a huge waste. Fluidized solidified soil is a mixture of various discarded slag, soil solidifier and water in a certain proportion and meets certain performance indicators. It is a green and innovative material that can replace lime soil foundations, crushed stone concrete, etc. in some places, and has great social significance in energy conservation, emission reduction and solid waste utilization.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings of the present invention.

[0036] Example

[0037] like Figures 1 to 8 As shown: The embodiment provides a fluidized solidified soil production system based on automation technology, which mainly includes a delivery device 1, a screening device 5, a stirring device 12, a water storage device 14, a solidifying agent storage device 15, a mud extraction device 27 and a control device 4.

[0038] The delivery device 1 is used to receive the debris generated during the construction process and deliver the debris to the first crawler conveyor 2. The delivery device 1 can be a bin-type structure with a large upper portion and a small lower portion, and has a conical shape. A blocking fence for blocking large stones can be provided at its delivery port to remove large stones and achieve primary screening.

[0039] The screening device 5 is used to receive the debris transmitted from the first crawler conveyor 2 and screen it through the drum screen 6. A funnel storage 7 for receiving the screened debris is provided directly below the drum screen 6. An electric bin door 8 is provided at the bottom of the funnel storage 7 and a second crawler conveyor 10 is provided directly below it. After the electric bin door 8, the debris falls to the second crawler conveyor 10.

[0040] The drum screen 6 can be cylindrical and rotate about its central axis. The drum screen 6 is tilted at 20° to 40° (e.g., preferably 30°), with its inlet located at the top and connected to the outlet of the first crawler conveyor 2. Furthermore, a residual material storage 11 can be provided at the outlet of the drum screen 6. The residual material after screening by the drum screen 6 is received by the residual material storage 11 for subsequent reuse.

[0041] A pressure sensor 9 may be provided on the inner side of the electric door 8 of the funnel storage 7. The pressure sensor 9 detects the weight of the slag in the funnel storage 7 in real time and transmits the information to the control device 4. The control device 4 sends an opening and closing signal to the electric door 8 to control the opening and closing of the electric door 8. When the weight of the material reaches a preset value, the electric door 8 automatically opens. The electric door 8 can be electrically controlled by an electric push rod, for example.

[0042] The stirring device 12 is used to receive the slag transmitted from the second crawler conveyor 10 and send it into the stirring barrel 13 for stirring; the power output end of the stirring motor 17 in the stirring device 12 is connected to the stirring shaft 19 located in the stirring barrel 13, and a number of stirring blades 20 are fixed on the stirring shaft 19; the stirring blades 20 are a three-section structure and include a curved rod 21, a long plate-shaped blade 22 and a third-section plate-shaped blade 23 connected in sequence, the curved rod 21 is connected to the stirring shaft 19, the long plate-shaped blade 22 is installed at an angle of 20° to 40° (for example, preferably 30°) to the stirring shaft 19, and the third-section plate-shaped blade 23 is radially parallel to the stirring barrel 13 and fits with the bottom of the barrel. The blade structure can fully stir the fluidized solidified soil inside; in addition, the stirring barrel 13 may be provided with an air vent 18 to discharge the exhaust gas generated during the stirring process.

[0043] In some embodiments, the conveying motor 3 of the first crawler conveyor 2, the second crawler conveyor 10 and the stirring motor 17 of the stirring device 12 are connected with encoders, which detect the speed of the relevant motors in real time and transmit the information to the control device 4. The control device 4 sends a control signal to the relevant motor to monitor the power and speed of the motor in real time and can set the stirring time and stirring rate on the controller device.

[0044] An electronic liquid level gauge 24 may also be provided in the mixing barrel 13. The electronic liquid level gauge 24 detects the liquid level in the barrel in real time and transmits the information to the control device 4. When the liquid level in the barrel exceeds the calibrated liquid level height, the stirring motor 17 can transmit and receive the signal of the control device 4, quickly stop, and issue an alarm.

[0045] The water storage device 14 is used to store production water and deliver it to the mixing barrel 13 for mixing with the slag. The curing agent storage device 15 is used to store production curing agent and deliver it to the mixing barrel 13 for mixing with the slag. Both the water storage device 14 and the curing agent storage device 15 are equipped with electric valves 26, and their external motors 25 are equipped with magnetic flow valves 30. The magnetic flow valves 30 monitor the flow rate of liquid delivered to the detection barrel in real time and transmit this information to the control device 4. The control device 4 sends an opening and closing signal to the electric valves. When the liquid output reaches a predetermined amount, the electric valves 26 automatically close. The electric valves 26 can be, for example, existing electric ball valves or electric butterfly valves. When the conveyor device transports materials to the mixing barrel 13, the water storage device 14 and the curing agent storage device 15 simultaneously deliver water, curing agent, and other materials to the mixing barrel 13.

[0046] The slurry extraction device 27 is used to extract the solidified soil after processing in the mixing drum 13. The slurry extraction device mainly includes a slurry pump 28. Its extraction motor 29 is also regulated by the control device 4. The speed of the extraction motor 29 can be set to adjust the extraction and output rate of the slurry pump 28. If the control device 4 detects that the extraction motor 29 is rotating too fast or the power is too high, it can automatically reduce the material feeding speed of the crawler conveyor system or directly stop the equipment.

[0047] The control device 4 is connected to the screening device 5, the stirring device 12, the water storage device 14, the curing agent storage device 15 and the driver in the mud extraction device (wired connection or wireless connection) for production control of the production system.

[0048] In some embodiments, the control device 4 includes a proximal control module and a remote control module arranged in parallel; the proximal control module receives signals and sends instructions by a PLC programmable logic controller to realize on-site control of the production system; the remote control module receives signals and sends instructions by a compiled (for example, python programming) STM32 microcontroller to realize remote control of the production system.

[0049] The PLC programmable logic controller can be of stacked or integral structure, which is compact, low cost and occupies a small area. It can be installed on the side wall of the upper reactor 3. It also has basic functions such as logic operation, timing, counting, shifting, self-diagnosis, and monitoring. It can also have analog input / output, arithmetic operation, data transmission and communication functions to meet the needs of various components of the equipment; the switch output interface can be of thyristor output type or transistor output type to meet the requirements of fast response speed and high action frequency required by the operation of various components of the solidified soil mixing equipment.

[0050] The high-performance ARM Cortex-M core of the STM32 microcontroller can easily handle complex tasks. In addition, the STM32 integrates a variety of peripheral interfaces, such as ADC, DAC, UART, etc., and supports multiple communication protocols, such as SPI and I2C, to facilitate data interaction with other devices; the STM32 microcontroller is programmed in Python, making it easier for users to learn and use.

[0051] The control device 4 can pre-set the weight of the material screened by the screening device 5 and the speed of the crawler conveyor, and automatically adjust the amount and dosage according to the preset ratio of material, curing agent, water, etc. The control device 4 can control the transmission speed of the crawler conveyor system and adjust the power of the mixing motor 17 in real time based on the motor speed signal transmitted by the encoder. If the encoder indicates abnormal motor speed or the impeller hits a large stone, the control device 4 can automatically adjust the motor speed or control the entire equipment to immediately stop working and issue an alarm.

[0052] The above is only an embodiment of the present invention, and the common knowledge such as the specific structure and characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several variations and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
