[0002] Premixed liquid solidified soil is a mixture formed by mixing various discarded soil residues, soil solidifying agents, and water in a certain proportion and meeting certain performance indicators. This 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.

[0003] During the construction process at a construction site, a large amount of waste soil residues will inevitably be generated.

[0043] As shown in the figure, a fully automatic pre-mixed liquid solidified soil continuous screening, mixing and pumping integrated device includes a single-belt screen screening system 2, a PLC programmable logic controller 1, and a solidified soil mixing equipment. The single-belt screen screening system 2 includes a weighable belt conveyor 28 with an automatic weighing function, a feeding bin 29, and a primary screening bin 30. The weighable belt conveyor 28 is used to transmit signals to the PLC programmable logic controller 1, and at the same time receive instructions from the PLC programmable logic controller 1 to adjust the speed of the crawler conveyor of the single-belt screen screening system 2 for materials.

[0044] The feeding bin 29 of the single-belt screen screening system 2 is used to receive the waste soil generated in the construction project, and the primary screening bin 30 can be used to filter out the materials with particle sizes meeting the requirements from the waste soil and put them into the weighable belt conveyor 28. At the same time, the PLC programmable logic controller 1 can automatically adjust the feeding of water and curing agent according to the speed of the transported materials, so that the materials, water and curing agent are transported to the solidified soil mixing equipment through the single-belt screen screening system 2 according to a certain ratio.

[0045] The solidified soil mixing equipment includes an upper mixing kettle 3 and a lower storage bin 4. Two sets of mixing shafts are vertically inserted through the side wall of the upper mixing kettle 3 from top to bottom in sequence. The mixing shaft located above is a set of large-diameter ribbon agitators 5 symmetrically arranged on the left and right. The impeller of this mixing shaft is a ribbon impeller, which is used for preliminary rough mixing and mixing of materials, water, and solidifying agents. The mixing shaft located below the ribbon agitator 5 is a set of first spiral augers 6 symmetrically arranged on the left and right. A set of first spiral augers 6 symmetrically arranged on the left and right consists of two pairs of spiral shafts. The two pairs of spiral shafts are symmetrically distributed left and right. The blades of the two pairs of spiral shafts are all shafted spiral blades. The installation directions of the spiral blades of each pair of spiral shafts are left-handed on the left side and right-handed on the right side. The spiral shafts all rotate clockwise, which is used to convey the slurry after preliminary mixing of materials, water, and solidifying agents to the second spiral auger 13 located below one end of the upper mixing kettle 3.

[0046] Specifically, the impeller blades of the ribbon agitator 5 are made of flat steel, welded or bolted to the hub. The number of impeller blades is four. It has a large diameter and a low rotation speed. The power is mainly consumed in the overall flow, which is beneficial to macroscopic mixing. After the materials, water, and solidifying agents are preliminarily mixed by the ribbon agitator 5, a medium with a relatively high viscosity is formed, and due to the action of gravity, it enters the first spiral auger 6 in the upper mixing kettle 3.

[0047] The first spiral auger 6 includes two pairs of first spiral shafts. The blades of each pair of first spiral shafts are installed in a left-handed manner on the left side and a right-handed manner on the right side, which maximally ensures the transportation and conveyance of the slurry in the first spiral auger 6.

[0048] The ribbon agitator 5 in the upper mixing kettle 3 is connected with a first driven sprocket 7 and a second driven sprocket 8. The first driven sprocket 7 and the second driven sprocket 8 are used to drive the ribbon agitator 5 to rotate. The first driven sprocket 7 and the second driven sprocket 8 are connected with a driving sprocket 9. A driving sprocket motor 10 corresponding to the driving sprocket 9 is arranged on the side wall of the upper mixing kettle 3. A first driven sprocket motor 11 and a second driven sprocket motor 12 are arranged on the side wall of the upper mixing kettle 3. The first driven sprocket motor 11 and the second driven sprocket motor 12 are used to drive the first spiral auger 6 to rotate. The first driven sprocket motor 11 and the second driven sprocket motor 12 are located below the driving sprocket 9. And the first driven sprocket 7, the second driven sprocket 8, the first driven sprocket motor 11, and the second driven sprocket motor 12 are all symmetrically distributed.

[0049] A pair of double-layer paddle agitators 14, an electronic liquid level gauge 18, and a slurry pump group are arranged inside the lower storage bin 4. A set of second spiral augers 13 is arranged between the upper mixing kettle 3 and the lower storage bin 4.

[0050] After the mud is conveyed by the first spiral auger 6, it falls into the second spiral auger 13 located between the upper stirring kettle 3 and the lower storage bin 4 and on the side of the motor on the side wall of the upper stirring kettle 3. The second spiral auger 13 is vertically distributed with both the first spiral auger 6 and the ribbon mixer 5.

[0051] The second spiral auger 13 includes a pair of second spiral shafts distributed oppositely. The second spiral shafts are provided with shaft spiral blades, and one end of each second spiral shaft is provided with a second spiral auger motor 26. The second spiral auger 13 is installed with the left side rotating counterclockwise and the right side rotating clockwise; in the direction of the front view, the two oppositely installed second spiral shafts both rotate counterclockwise, which serves to convey the mud in the upper stirring kettle 3 into the top hole 22 of the lower storage bin 4.

[0052] After the mud is conveyed by the second spiral auger 13, it falls into the lower storage bin 4 through the hole 22. On the double-layer paddle mixer 14 in the lower storage bin 4, there are upper and lower paddle impellers with opposite directions inclined, which can better stir the mud. The mud pump group includes a first mud pump 15 and a second mud pump 16. Both the first mud pump 15 and the second mud pump 16 are arranged at the bottom of the lower storage bin 4. Among them, the first mud pump 15 is used to send the mud at the bottom of the lower storage bin 4 to the upper paddle impeller 17 of the double-layer paddle mixer 14 on the upper side of the lower storage bin 4 for re-stirring. The second mud pump 16 is electrically connected to the electronic liquid level gauge 18; when the electronic liquid level gauge 18 reaches the calibrated liquid level height, the second mud pump 16 starts to work and pumps the processed premixed liquid solidified soil outside the mixer.

[0053] A power supply motor 21 is arranged on the side wall of the lower storage bin 4. The output end of the power supply motor 21 is provided with a small pulley 20. When the power supply motor 21 starts, it drives the small pulley 20 to rotate. The small pulley 20 is rotationally connected to a large pulley 19 through a belt, and the large pulley 19 is rotationally connected to the double-layer paddle mixer 14, so as to realize the driving of the double-layer paddle mixer 14 by the large pulley 19.

[0054] At both ends of the ribbon mixer 5 of the upper stirring kettle 3, the connections between the first spiral auger 6, the double-layer paddle mixer 14 and the large pulley 19 are all provided with diamond-shaped support bearings 27 to achieve support.

[0055] The driving sprocket motor 10, the first driven sprocket motor 11, the second driven sprocket motor 12, the second spiral auger motor 26, the power supply motor 21 and the second mud pump 16 are all electrically connected to the PLC programmable logic controller 1 through the installation of encoders, and signals can be transmitted to the PLC programmable logic controller 1 and its instructions can be read.

[0056] Several pipes with different heights are arranged on the side wall of the lower storage bin 4. Specifically, a first pipe 23 is arranged in the middle of the side wall of the lower storage bin 4, and two second pipes 24 and a third pipe 25 are arranged at the upper position of the side wall. The first pipe 23, the second pipe 24 and the third pipe 25 are arranged to prevent the electronic liquid level gauge 18 from malfunctioning or the PLC programmable logic controller 1 from being damaged, resulting in excessive mud in the lower storage bin 4 and causing equipment damage.

[0057] The PLC programmable logic controller 1 is arranged on the side wall of the upper stirring kettle 3. Generally, a stacked or integral structure form is selected, which has a compact structure, low cost and small floor area. At the same time, it also has basic functions such as logical operation, timing, counting, shifting, self-diagnosis and monitoring, and can also have functions such as analog input / output, arithmetic operation, data transmission and communication to meet the requirements between the various components of the equipment. The switch quantity output interface can be selected as the thyristor output type or the transistor output type to meet the characteristics of fast response speed and high action frequency required during the operation of each component of the solidified soil mixing equipment.

[0058] In this embodiment, the PLC programmable logic controller 1 is used to control the feeding speed of the single-belt screening system 2 and automatically adjust the feeding amounts of water and curing agent according to the feeding amount; the PLC programmable logic controller 1 is used to control the speeds of the spiral ribbon agitator 5 and the second spiral auger motor 26 and adjust the stirring intensity; the PLC programmable logic controller 1 is also used to automatically control the output speeds of the spiral ribbon agitator 5, the lower storage bin 4 and the second mud pump 16.

[0059] Specifically, the interface of the PLC programmable logic controller 1 is connected to the single-belt screening system 2, the electronic liquid level gauge 18, the driving sprocket motor 10, the first driven sprocket motor 11, the second driven sprocket motor 12, the power supply motor 21, the second spiral auger motor 26 and the second mud pump 16. The construction site can set the program according to the needs. The PLC programmable logic controller 1 can adjust the powers of the driving sprocket motor 10, the first driven sprocket motor 11 and the second driven sprocket motor 12 according to the transmission speed and material weight of the weighable belt conveyor 28 of the single-belt screening system 2.

[0060] When the PLC (Programmable Logic Controller) 1 identifies that the rotational speeds of the driving sprocket motor 10, the first driven sprocket motor 11, and the second driven sprocket motor 12 are too high or the powers are too large, it transmits signals to the PLC 1; the PLC 1 sends signals to the single-belt screen screening system 2 to adjust the material input speed; the electronic liquid level gauge 18 transmits the liquid level signals to the PLC 1 in real time. When the liquid level is greater than the set value, the second slurry pump 16 starts to work to output the premixed liquid solidified soil outward. If the liquid level shows too high, the impeller hits larger stones, and the power is too large, the PLC 1 can automatically adjust the transmission speeds of the weighable belt conveyor 28 and the first screw auger 6 or control the entire set of equipment to stop working immediately and wait for maintenance.

[0061] Therefore, the present invention adopts the above-mentioned fully automatic integrated equipment for continuous screening, mixing, pumping of premixed liquid solidified soil. Using the PLC to control the automatic operation of the entire set of equipment and the safety monitoring equipment, the process is simple and the operation is convenient. The manual processing required for the implementation of all processes is very simple and easy. It effectively improves the construction efficiency of premixed liquid solidified soil, speeds up the construction progress, and shortens the construction period.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions of the present invention or make equivalent replacements, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
