Description

Technical Field

[0001] This invention patent relates to the technical field of fluidized solidified soil, and more specifically, to a mobile fluidized solidified soil production and transportation vehicle. Background Technology

[0002] With the development of urban construction, old city renovation, and underground transportation in Shenzhen, the disposal of construction waste such as excavated soil and mud has gradually become a problem for urban development. According to statistics, my country generated 3 billion tons of construction waste in 2020, and the amount of construction waste is increasing year by year. Among them, excavated soil accounts for more than 70%, making it the largest part of urban waste.

[0003] Currently, the main method for disposing of construction waste in my country is to transport it to construction waste dumps. This method increases transportation costs, occupies valuable land resources, and causes serious environmental pollution and safety problems due to the large-scale dumping of construction waste.

[0004] In existing technologies, 30-50% of the sand can be recovered from construction waste after screening and washing. The remaining tailings slurry is then dewatered using a filter press to form low-moisture sludge cakes. With the sand recovered and the moisture removed by filtration, the remaining sludge cakes have a volume only 30-40% of the original construction waste. However, due to the small particle size of the remaining sludge cakes, they are difficult to utilize as resources. Therefore, even with the sand recovery method, 30-40% of the sludge cakes still need to be transported and disposed of. Most of these sludge cakes are transported to docks or landfills for disposal, resulting in high transportation and disposal costs.

[0005] To address the aforementioned issues, a process for producing fluidized solidified soil involves directly adding a solidifying agent to the tailings sludge after screening and separating sand from engineering waste soil, and then mixing it to produce fluidized solidified soil. This eliminates the need for the sand washing tailings sludge to be filtered into cakes using a filter press, thus reducing the sludge filtration process and lowering production costs at the sand washing plant. Furthermore, the fluidized solidified soil can be transported to the construction site in sludge tanker trucks for use in underground spaces, such as underground utility tunnels and backfilling of foundation pits and trenches.

[0006] Although mixing tailings into fluidized bed soil solves the problem of transporting and disposing of slag cakes, the production area for fluidized bed soil is quite large, and most construction sites cannot provide enough space for it. A typical fluidized bed soil production site consists of a slurry pool, multiple solidifying agent silos, and multiple slurry tanks, thus requiring a large area, generally over 300 square meters.

[0007] Currently, most fluidized bed solidification production sites are located in sand washing plants in the suburbs. Although this solves the production site problem, the transportation cost of transporting fluidized bed solidification to the city is too high because sand washing plants are generally far from the city. Summary of the Invention

[0008] The purpose of this invention is to provide a mobile production and transportation vehicle for fluidized solidified soil, which aims to solve the problem that in the prior art, the production site area for fluidized solidified soil is large, and general construction sites cannot provide enough area for setting up a fluidized solidified soil production site.

During the rotation of the mixing shaft, the multiple mixing blades mix the solidifying agent and slurry in the mixing chamber to form the fluidized solidified soil. Before the vehicle body travels to the construction site, a curing agent is first placed in the storage chamber. After the vehicle body arrives at the construction site, mud is added to the mixing chamber, and then the curing agent in the storage chamber is added to the mixing chamber. During the process of the vehicle body traveling from the construction site to the backfill site, the mixing shaft rotates, and multiple mixing blades mix the curing agent and mud in the mixing chamber.

[0024] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0025] The present invention provides a mobile fluidized solidified soil production and transportation vehicle, including a vehicle body, a storage tank 200 and a horizontally arranged mixing tank 400 on the vehicle body. The storage tank 200 has a storage cavity for storing powdered solidifying agent, and the mixing tank 400 has a horizontally arranged mixing cavity for containing slurry and solidifying agent. The storage cavity and the mixing cavity are connected by a conveying pipe 300, and the solidifying agent in the storage tank 200 is conveyed to the mixing cavity through the conveying pipe 300. The mixing chamber is equipped with a rotating mixing shaft 500, which extends along the axial direction of the mixing chamber. The mixing shaft 500 is equipped with multiple mixing blades 510. During the rotation of the mixing shaft, the multiple mixing blades 510 mix the curing agent and slurry in the mixing chamber to form fluidized solidified soil. Before the vehicle body travels to the construction site, a curing agent is first installed in the storage chamber. After the vehicle body arrives at the construction site, mud is added to the mixing chamber, and then the curing agent in the storage chamber is added to the mixing chamber. During the process of the vehicle body traveling from the construction site to the backfill site, the mixing shaft 500 rotates, and multiple mixing blades 510 mix the curing agent and mud in the mixing chamber.

[0026] The aforementioned mobile fluidized solidified soil production and transportation vehicle adds slurry from the construction site to the mixing chamber and transports the solidifying agent from the storage tank 200 to the mixing chamber through the conveying pipe 300. During the process of traveling between the construction site and the backfill site, the mixing blades 510 mix the solidifying agent and slurry in the mixing chamber to form fluidized solidified soil. The fluidized solidified soil is used for backfilling underground pipe corridors and foundation pits, effectively solving the problem of no production site for fluidized solidified soil production in urban areas. It has a short stop time at the construction site, minimal impact on the construction site, and is low in cost and high in efficiency.

[0027] Specifically, the front of the vehicle body has a cab 100, in which a driver's cab is located. The mixing tank 400 is located at the rear of the vehicle body, and the storage tank 200 is located between the cab 100 and the mixing tank 400.

[0028] A weighbridge 210 is installed below the storage tank 200, and a support is installed on the weighbridge 210. The support forms a cavity, and the storage tank 200 is fixed in the cavity. There is a suspended area between the bottom of the storage tank 200 and the weighbridge 210. In this way, the support stands on the weighbridge 210, and the weighbridge 210 facilitates the measurement of powder materials.

[0029] The storage tank 200 has a discharge port 401 at its bottom that connects to the storage chamber, and the mixing tank 400 has an inlet at its top that connects to the mixing chamber. The conveying pipe 300 is arranged at an inclination, with its lower end connected to the discharge port 401 and its upper end connected to the inlet. The curing agent in the storage chamber falls from top to bottom into the conveying pipe 300 through the discharge port 401, and is conveyed upwards along the conveying pipe 300, entering the mixing chamber from top to bottom through the inlet. In this way, the conveying pipe 300 can be installed in the reserved suspended area, and the curing agent is transported upwards and falls into the mixing chamber under the action of gravity.

[0030] The conveying pipe 300 has a conveying chamber that extends axially along the conveying pipe 300. A screw rod is installed in the conveying chamber, extending coaxially with the conveying pipe 300. By rotating, the screw rod conveys the curing agent in the storage chamber upwards along the conveying pipe. Thus, the upward conveying of the curing agent is achieved through screw-feeding.

[0031] Specifically, the lower end of the conveying pipe 300 has an upwardly extending longitudinal section 310, which is aligned and connected to the discharge port 401 from bottom to top; the upper end of the conveying pipe 300 has a downwardly extending longitudinal section 320, which is aligned and connected to the inlet from top to bottom. The curing agent in the storage chamber falls from top to bottom into the upward section 310, and as the screw rotates, it is tilted upward and transferred to the downward section 320, entering the mixing chamber through the inlet. This forms a better feeding track.

[0032] The front end of the mixing tank 400 is connected to a hydraulic telescopic rod, and the bottom of the rear end of the mixing tank 400 is provided with a discharge port. By extending and retracting the hydraulic telescopic rod, the forward and backward tilt angle of the mixing tank 400 can be adjusted. In this way, the front end of the mixing tank 400 can be lifted at a small angle to facilitate material discharge.

[0033] The front and rear ends of the mixing tank 400 are respectively covered with steel plates 540. A supporting steel frame 530 is provided between the storage tank 200 and the front end of the mixing tank 400. The ends of the mixing shaft 500 are respectively inserted into the steel plates 540 and are rotatably arranged with the steel plates 540. The mixing shaft 500 extends outward to form a drive section, which is movably mounted on the supporting steel frame 530 and connected to a motor 520. The motor 520 drives the mixing shaft 500 to rotate. In this way, the supporting steel frame 530 is used to support the horizontally extending mixing shaft 500, and the design of the steel plates 540 ensures that the mixing tank 400 can withstand the weight of the mixing shaft 500.

[0034] In this embodiment, the plurality of stirring blades 510 include fixed blades fixedly connected to the stirring shaft 500 and a plurality of movable blades 551 arranged movably along the axial direction of the stirring shaft 500; the stirring shaft 500 has a reduced diameter section 501 in the middle, and a movable ring 550 arranged movably along the axial direction of the reduced diameter section 501 is sleeved on the reduced diameter section 501, and a plurality of movable blades 551 are disposed on the movable ring 550, and the length of the reduced diameter section 501 is greater than the width of the movable ring 550; A guide rail 502 protrudes from the reduced diameter section 501 and is movably embedded in the movable ring 550. The guide rail 502 restricts the movable ring 550 from rotating circumferentially relative to the reduced diameter section 501. During the rotation of the stirring shaft 500, the movable ring 550 rotates synchronously with the stirring shaft 500. During the rotation, the multiple movable blades 551 experience changes in force, driving the movable ring 550 to reciprocate along the axial direction of the reduced diameter section 501. On both sides of the movable ring 550, there are elastic rings 560. The elastic rings 560 are movably fitted around the outer periphery of the reduced diameter section 501. There is an annular gap between the inner wall of the movable ring 550 and the outer periphery of the reduced diameter section 501. Multiple rotatingly arranged rolling balls 552 are protruding from the inner wall of the movable ring 550. The multiple rolling balls 552 are arranged at intervals along the circumference of the reduced diameter section 501. The rolling balls 552 are placed in the annular gap and move against the outer periphery of the reduced diameter section 501. During the reciprocating movement of the movable ring 550 along the axial direction of the reduced diameter section 501, the elastic ring 560 contracts or stretches and deforms, and the rolling balls 552 roll as the movable ring 550 moves. In this way, the design of the guide rail 502 restricts the circumferential rotation of the movable ring 550, the design of the rolling ball 552 reduces the friction force that the movable ring 550 needs to overcome when moving along the narrowed section 501, and the design of the elastic ring 560 prevents the movable ring 550 from hitting the front and rear ends of the narrowed section. The design of the movable ring 550, the movable blade 551 and the elastic ring 560 can promote the axial movement of the mixture in the mixing chamber during the mixing process, so as to promote uniform mixing and thorough mixing.

[0035] In this embodiment, during the process of pouring the curing agent into the mixing chamber, the inlet is connected to the inlet pipe 610, which is arranged at the top of the mixing chamber and extends along the length of the mixing chamber. The bottom of the inlet pipe 610 is provided with multiple discharge holes. One end of the inlet pipe 610 is connected to the inlet, and the other end of the inlet pipe 610 extends to the outside of the mixing chamber and is connected to the exhaust fan 600. The exhaust fan 600 is connected to the return pipe 620, which is connected to the inlet. The inlet, the inlet pipe 610, the exhaust fan 600, and the return pipe 620 form a circulating flow channel. The curing agent enters the feed pipe 610 through the inlet. When the exhaust fan 600 is activated, the curing agent flows axially along the feed pipe 610. Part of the curing agent falls into the mixing chamber through the discharge port, while the rest enters the return pipe 620 and flows back to the inlet, re-entering the feed pipe 610. This design of the feed pipe 610 ensures that the curing agent is evenly distributed throughout the mixing chamber. The exhaust fan 600 and the return pipe 620 accelerate the movement of the curing agent within the feed pipe 610, ensuring that some curing agent falls into the mixing chamber through each discharge port.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
