Description

Technical Field

[0001] This invention belongs to the technical field of fluidized solidified soil preparation equipment, and specifically relates to a mobile fluidized solidified soil mixing equipment with an inclined grate feeding system. Background Technology

[0002] Solidified soil is a soil material with a certain strength obtained by solidifying soil particles with cement or other solidifying agents. Fluidized solidified soil refers to pre-mixed solidified soil with good flowability, strong self-compacting ability, high construction efficiency, and reduced consumption of natural sand and gravel resources. It can be poured, offering excellent construction convenience. It can be pumped and other methods of construction, suitable for road base courses, underground pipeline backfilling, backfilling and pouring of various foundation pits, trenches, and mine pits. It can also be widely used in the reinforcement of roadbeds and building foundations, as well as in the resource utilization of construction waste. The resulting solidified soil has high strength, controllable quality, and low cost.

[0003] Premixed fluidized bed backfill material is a new type of environmentally friendly material that reduces costs and increases efficiency. It uses reclaimed soil from construction waste and recycled fine aggregate as raw materials, adds a special curing agent and water, and after thorough mixing, forms a reinforcement material with strong fluidity and good self-sealing properties. It is used for backfilling and pouring of various trenches and foundation pits, and for reinforcing roadbeds, building foundations, and other similar applications. This recycled fluidized bed backfill material boasts superior quality and significant advantages. It can replace natural lime-soil for backfilling and is suitable for backfilling in small areas, narrow spaces, deep areas, or irregularly shaped structures. Features of the fluidized bed backfill material include: convenient pumping or chute construction; strong fluidity and good self-sealing properties; short curing time; good stability; no settlement; good impermeability; and environmental friendliness.

[0004] Current methods of producing fluidized solidified soil mainly employ stationary mixing plants or traditional concrete mixing equipment. However, with the development of urban infrastructure, the following technical shortcomings have gradually become apparent in the application of traditional equipment: (1) Existing mixing equipment usually does not perform screening and crushing. After screening, the earthwork has many transfer links, large material drop and serious dust. The integration of the whole set of equipment is low. Most of the equipment is fixed and the disassembly and assembly are complicated. It cannot meet the needs of rapid production in multiple construction areas, especially in complex environments and small spaces where it is difficult to assemble complete production equipment. (2) The soil sources at the construction site are complex, usually containing large hard soil blocks, bricks, stones, concrete fragments, plant roots and other impurities. The traditional feeding method directly puts the soil into the hopper with only a grate. When wet and sticky soil enters the screening mechanism, it is easy to stick to the screen surface, which reduces the screening efficiency and may even cause the equipment to stop. Various impurities can also easily cause blockage of the conveying mechanism. At the same time, it requires real-time manual monitoring and manual assistance to remove debris. The existing equipment lacks an adaptive structure for the complex soil source environment at the site and cannot achieve the true meaning of "soil extraction, on-site improvement and on-site use". (3) Existing equipment mainly relies on manual experience to control the ratio of soil, water and curing agent. Moreover, the materials are added to the equipment at the same time for mixing. This will result in insufficient mixing, the agent will not be able to play its full role, and the performance of different batches of fluidized solidified soil will be greatly different, and the mixing reaction will be insufficient. Traditional mixing chambers mix in one direction, and the soil and solidified slurry are not mixed evenly. This can easily lead to local insufficient solidification and segregation, resulting in poor stability of continuous production.

[0005] Therefore, a new fluidized solidified soil mixing device needs to be designed to address the shortcomings of existing technologies.

[0006] In view of this, we propose a mobile fluidized solidified soil mixing equipment with an inclined grate feeding system to solve the existing problems. Summary of the Invention

[0012] Preferably, the crushing and feeding device includes a receiving bin, a first drive mechanism fixedly disposed on the side of the support frame, a transmission shaft passing through and rotatably disposed between the two ends of the receiving bin, and a scraper fixedly disposed between the two ends of the transmission shaft. The scraper has at least two scraper blades distributed at equal angles. The gap between the outer surface of the scraper blade and the inner wall of the receiving bin is less than one centimeter. The drive end of the first drive mechanism is fixedly connected to the transmission shaft. Multiple stirring components are fixedly disposed on the circumference of the transmission shaft. Each of the multiple stirring components is rotatably disposed with a crushing blade. A feeding port is opened at the bottom of the receiving bin.

[0013] Preferably, the conveying device includes a conveying bracket, a plurality of bearing rollers, a conveyor belt, and a second driving mechanism.

[0016] Preferably, the driving ends of the first stirring drive mechanism and the second stirring drive mechanism rotate in opposite directions, and both have multiple connecting parts fixedly arranged on their outer periphery, with multiple spiral stirring blades fixedly arranged on the multiple connecting parts.

[0017] Preferably, the feeding pool is a rectangular trough, and a spray valve is fixedly installed at the end of the feeding pool.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention integrates an inclined cylindrical grate screening device, a crushing and feeding device, a conveying device, a mixing tank, a mixing reactor, and a feeding tank onto a single support frame. This eliminates the multi-stage transfer and separate frame structure of traditional equipment, significantly reducing material transfer drop and dust generation. Simultaneously, the entire screening operation is enclosed and protected by a dust cover, completely resolving material scattering and dust pollution issues. The entire unit is a modular, integrated device, requiring no complex on-site assembly. It can be directly moved and relocated, adapting to confined spaces and rapid multi-area construction, effectively solving the shortcomings of traditional fixed equipment such as cumbersome disassembly and assembly, poor mobility, and inability to quickly commence production.

[0019] This invention employs a rotary inclined cylindrical grate screening device with adjustable tilt angle. Combined with a hydraulic drive mechanism, the screening tilt angle can be adjusted as needed, and a belt drive mechanism allows for adjustment of the rotary screening speed. The grate rings feature a gradually increasing spacing structure with denser inlets and sparser outlets, effectively adapting to the screening of wet, sticky soil materials and preventing material accumulation and adhesion to the screen, thus avoiding screen blockage and machine downtime. The equipment can pre-screen various impurities such as bricks, stones, concrete fragments, and plant roots. Subsequent crushing and feeding devices further break down the materials, preventing blockages in the conveying mechanism at the source. No real-time manual monitoring or cleaning is required, truly enabling on-site soil sampling, on-site improvement, and direct on-site use, significantly improving adaptability to complex soil conditions and enhancing automation.

[0020] This invention employs a staged operation structure involving premixing of reagents, layered feeding, and bidirectional counter-current stirring. The mixing reactor independently premixes water and the solidifying agent, which is then precisely discharged into the mixing tank via gravity flow due to varying heights. This eliminates the traditional method of simultaneous feeding of all materials, ensuring full activation of the reagents and uniform, controllable proportions, thus avoiding errors caused by manual, experience-based feeding. Simultaneously, the mixing tank is equipped with two sets of opposing stirring drive mechanisms—a first and a second—that create a double-swirling, counter-current stirring effect through reverse spiral blades. This completely eliminates the uneven mixing, insufficient localized solidification, and segregation defects inherent in unidirectional stirring, resulting in a more complete reaction between the soil and the solidified slurry. This leads to highly uniform performance of the finished fluidized solidified soil in each batch, significantly improving the stability of continuous production and the quality of the final product.

[0029] This embodiment provides a mobile fluidized solidified soil mixing device with an inclined grate feeding system proposed in this invention, such as... Figures 1 to 4 As shown, the device includes a support frame 1. In use, the support frame 1 is irregularly shaped to support other related structural devices. Its bottom is a platform. An inclined cylindrical grate screening device 2 is movably installed on the upper part of the support frame 1. A crushing and feeding device 3 is fixedly installed in the middle of the support frame 1. The crushing and feeding device 3 is located vertically below the inclined cylindrical grate screening device 2. A conveying device 4 is horizontally installed at the lower part of the support frame 1. The conveying device 4 is located below the crushing and feeding device 3. In use, the inclined cylindrical grate screening device 2 is movably installed at the top of the support frame 1, so that the material fed in is fully rotated and screened. The larger material that is not suitable as raw material is screened out by its own lifting and tilting. The suitable material falls into the crushing and feeding device 3 by its own gravity. After being fully mixed and crushed in the crushing and feeding device 3, the material passes through the feed port 13 at its lower part to the conveying device 4 and is fed to the next processing station. A mixing tank 5 is provided between the bottom of the conveying device 4 away from the support frame 1 and the support frame 1. A mixing reactor 6 is connected to one side of the mixing tank 5, and a feeding tank 7 is connected to the other side. The bottom side of the mixing reactor 6 is higher than the top side of the mixing tank 5, and the bottom side of the mixing tank 5 is higher than the top side of the feeding tank 7. When in use, the material fed by the conveying device 4 is sprinkled into the mixing tank 5. At the same time, the medicine liquid and water in the mixing reactor 6 are fully mixed and discharged into the mixing tank 5 for further mixing, thereby achieving full mixing to form the finished fluidized solidified soil.

[0030] like Figures 1 to 3 , Figures 5 to 7 As shown, the inclined cylindrical grate screening device 2 further includes a feed end 201, a discharge end 202, a cylindrical grate 203, and a dust cover 204. The cylindrical grate 203 is rotatably disposed between the feed end 201 and the discharge end 202, and the dust cover 204 is fixedly disposed between the feed end 201 and the discharge end 202. In use, the dust cover 204 ensures that the inclined cylindrical grate screening device 2 will not cause dust pollution during the inclined screening process, and will not cause the material to scatter in all directions due to centrifugal force when the cylindrical grate 203 is at different inclination angles and different rotation screening speeds, so that the material gathers and falls into the next process. The support frame 1 and the feed end 201 are abutted against each other, and a hydraulic drive mechanism 205 is movably installed between them. In use, when the hydraulic drive mechanism 205 is not lifting, the feed end 201 normally rests against the upper side of the support frame 1. When the hydraulic drive mechanism 205 lifts, the feed end 201 separates from the support frame 1. At this time, the inclined cylindrical grate screening device 2 tilts and lifts, and the drive end of the hydraulic drive mechanism 205 drives the feed end 201 to lift, thereby driving the discharge end 202, the cylindrical grate 203, and the dustproof... The cover 204 moves accordingly. Since the outer periphery of the discharge end 202 is equipped with a bearing 206, and the bearing 206 is rotatably connected to the support frame 1 through the rotating component 207, the discharge end 202 can only rotate during use. This allows the inclined cylindrical grate screening device 2 to achieve an overall tilting and lifting effect, enabling the inclined cylindrical grate screening device 2 to screen materials at different angles. At the same time, due to the tilting effect, larger materials, such as bricks and cement blocks, are also screened out, resulting in higher material quality.

[0031] like Figures 1 to 3 , Figures 5 to 7As shown, the cylindrical grate 203 further includes several grate columns 2031 and several grate rings 2032. The grate rings 2032 are sleeved on the outer periphery of the grate columns 2031. In use, this sleeved assembly forms a cylindrical grate, enabling rotary screening to achieve the function of screening materials. The grate rings 2032 are arranged with gradually increasing spacing. In use, since the material is in a state of accumulation and compression when it is first fed into the inclined cylindrical grate screening device 2, the material falls relatively quickly. The grate rings 2032 at the inlet are arranged with increasing spacing, resulting in a denser grate rings and slower, less material discharge. Conversely, the grate rings 2032 at the outlet are relatively fewer, resulting in faster and more material discharge. This gradually increasing spacing design achieves a more uniform screening effect throughout the entire screening range, enabling the material fed into the inclined cylindrical grate screening device 2 to have a more uniform screening effect. At the same time, it also achieves the effect of uniform material discharge into the crushing and feeding device 3.

[0032] like Figures 1 to 3 , Figures 5 to 7 As shown, the feed end 201 further includes an outer support frame 2011 and an inner support frame 2012. The head end of the cylindrical grate 203 is rotatably assembled between the outer support frame 2011 and the inner support frame 2012. The outer support frame 2011 and the inner support frame 2012 are fixedly connected by a reinforcing guard 8. A feed inlet 9 extending into the inner support frame 2012 is fixedly provided on one side of the reinforcing guard 8. In use, the outer support frame 2011 and the inner support frame 2012 can restrict the cylindrical grate 203 and also provide support. The connection of the reinforcing guard 8 also achieves the effect of being fixed as one unit. A belt drive mechanism 10 is fixedly installed on the side of the outer support frame 2011. The drive end of the belt drive mechanism 10 is rotatably connected to the end of the cylindrical grate 203. In use, the cylindrical grate 203 is driven to rotate by the belt drive mechanism 10, so that the cylindrical grate 203 achieves the effect of rotary screening. By adjusting the rotation speed of the belt drive mechanism 10, the cylindrical grate 203 can achieve different screening efficiencies, thereby realizing the effect of adjustable feeding speed. The tail end of the hydraulic drive mechanism 205 is rotatably connected to the support frame 1, and the drive end of the hydraulic drive mechanism 205 is rotatably connected to the bottom of the outer support frame 2011. In use, by setting the hydraulic drive mechanism 205 and rotatably connecting its two ends, the hydraulic drive mechanism 205 can rotate at different small angles when it is extended to different lengths, thereby supporting the inclined cylindrical grate screening device 2 to achieve different inclination states.

[0033] like Figures 1 to 3 , Figure 8As shown, the crushing and feeding device 3 further includes a receiving bin 301, a first drive mechanism 302 fixedly mounted on the side of the support frame 1, a transmission shaft 303 passing through and rotatably mounted between the two ends of the receiving bin 301, and a scraper 11 fixedly mounted between the two ends of the transmission shaft 303. The scraper 11 has at least two scraper blades 12 distributed at equal angles. The gap between the outer surface of the scraper blades 12 and the inner wall of the receiving bin 301 is less than one centimeter. The drive end of the first drive mechanism 302 is fixedly connected to the transmission shaft 303. A plurality of agitators 30 are fixedly mounted on the circumference of the transmission shaft 303. 31. Each of the multiple mixing components 3031 is rotatably equipped with a crushing blade 3032. The bottom of the receiving bin 301 is provided with a feeding port 13. In use, the upper two sides of the receiving bin 301 have extended receiving sides. The first driving mechanism 302 drives the transmission shaft 303 to rotate. The transmission shaft 303 drives the mixing component 3031 fixedly connected to it, which in turn drives the crushing blade 3032 to rotate at high speed, achieving the effect of crushing, dispersing and evenly mixing the screened material. The crushed and evenly mixed material is scraped and pushed by the simultaneously rotating scraper 11 to the feeding port 13 for discharge.

[0034] like Figures 1 to 3 As shown, the conveying device 4 further includes a conveying support 401, a plurality of bearing rollers 402, a conveyor belt 403, and a second drive mechanism 404. The conveying support 401 is fixedly connected to the support frame 1 and serves to support the structural components of different parts of itself during use. The plurality of bearing rollers 402 are horizontally rotatably mounted on the inner side of the conveying support 401, and the conveyor belt 403 is wrapped around the outer periphery of the plurality of bearing rollers 402. During use, the second drive mechanism 404 drives the plurality of bearing rollers 402 to rotate, thereby driving the conveyor belt 403 to rotate, so as to achieve the effect of conveying materials. By adjusting the driving speed of the second drive mechanism 404, different transfer speeds of materials can be achieved. The second drive mechanism 404 is installed at the bottom of the conveyor support 401. The drive end of the second drive mechanism 404 is rotatably connected to a bearing roller 402 closest to the mixing tank 5. In use, the second drive mechanism 404 can drive the conveyor belt 403 to move. The conveying end of the conveying device 4 extends to the upper area of ​​the mixing tank 5. By extending this design, the material can be directly fed into the mixing tank 5 for mixing.

[0035] like Figures 1 to 2 , Figure 4 , Figures 9 to 10As shown, the mixing reactor 6 is further fixedly connected to the support frame 1. The mixing reactor 6 includes a reaction tank 601. A water supply device 602 and a stirring mechanism 603 are installed on the upper part of the reaction tank 601, and a dosing port 604 is opened on the upper part. The lower part of the mixing reactor 6 has a liquid discharge control gate 605 at the position above the stirring tank 5. In use, the water supply device 602 continuously and controllably supplies water to the reaction tank 601. At the same time, the stirring mechanism 603 starts stirring, and the operator adds the reagent to the reaction tank 601 through the dosing port 604, so that the reagent and water are fully stirred and mixed in advance. The fully mixed liquid is then discharged into the stirring tank 5 as needed through the liquid discharge control gate 605.

[0036] like Figures 1 to 2 , Figure 4 , Figure 11 As shown, the mixing tank 5 is further fixedly connected to the support frame 1. The mixing tank 5 is a long trough and a first stirring drive mechanism 501 and a second stirring drive mechanism 502 are installed at one end near the bottom of the mixing reactor 6. The driving ends of the first stirring drive mechanism 501 and the second stirring drive mechanism 502 both pass through both ends of the mixing tank 5. A discharge gate 504 is opened at the bottom of the end of the mixing tank 5 away from the mixing reactor 6. In use, the fully mixed fluidized solidified soil is discharged by controlling the discharge gate 504. A filter screen 503 is fixedly installed at an incline on the upper part of the mixing tank 5. In use, the previous process liquid is added to the mixing tank 5 to one-third, and then the material is added. When the material is added, the filter screen 503 disperses the material conveyed by the conveyor belt 403 and prevents the material from clumping and splashing when directly added to the mixing tank 5. By setting the first stirring drive mechanism 501 and the second stirring drive mechanism 502 to stir at the same time, the material and the liquid discharged from the previous process are more fully mixed.

[0037] like Figure 4 and Figure 11 As shown, the first stirring drive mechanism 501 and the second stirring drive mechanism 502 have opposite driving directions, and both have multiple connecting parts 14 fixedly arranged on their outer periphery. Multiple spiral stirring blades 15 are fixedly arranged on the multiple connecting parts 14. In use, the first stirring drive mechanism 501 drives the connecting parts 14 to drive the spiral stirring blades 15 to rotate inward in the direction of the material and the mixed medicine liquid, so as to fully dissolve and mix again. At the same time, the driving end of the second stirring drive mechanism 502 drives the connecting parts 14 thereon to drive the spiral stirring blades 15 to rotate inward as well. The two directions are opposite, so that the two swirling currents formed by the mixing of the material and the medicine liquid in the stirring tank 5 collide fully to achieve a further thorough mixing effect.

[0038] like Figure 4As shown, the feeding pool 7 is a rectangular trough, and a spray valve 701 is fixedly installed at the end of the feeding pool 7. In use, the prepared fluidized solidified soil can be stored for a short time and supplied as needed by controlling the spray valve 701.

[0039] The working principle of the mobile fluidized solidified soil mixing equipment with inclined grate feeding system based on Embodiment 1 is as follows: The equipment uses the support frame 1 as the overall load-bearing foundation. During operation, the tilt angle of the inclined cylindrical grate screening device 2 can be adjusted by the hydraulic drive mechanism 205 according to the soil conditions on site.

[0040] Material is fed in through inlet 9, and belt drive mechanism 10 drives cylindrical grate 203 to rotate. The grate column 2031 supports the grate and the grate ring 2032 has a gradually increasing spacing structure to achieve grading and screening, effectively removing large particles such as stones and hard soil. Dust cover 204 can suppress dust and material scattering throughout the process.

[0041] After screening, the qualified fine soil falls into the receiving bin 301 of the crushing and feeding device 3 below by gravity. The first driving mechanism 302 drives the transmission shaft 303 to rotate, driving the agitator 3031 and the crushing blade 3032 to break up the lumpy soil. At the same time, the scraper 11 and scraper 12 scrape off the accumulated material on the bin wall, and the homogenized material is transported from the feeding port 13 to the conveying device 4.

[0042] The second drive mechanism 404 drives the bearing roller 402 and the conveyor belt 403 to feed the material at a uniform speed, transporting the material to the top of the mixing tank 5. After being broken up twice by the filter screen 503, the material falls into the tank.

[0043] Meanwhile, the mixing reactor 6 is supplied with water by the water supply device 602 and dosing by the dosing port 604. After being premixed by the stirring mechanism 603, a uniform solidified slurry is formed. Taking advantage of the height difference of the equipment, the slurry flows into the mixing tank 5 by gravity after the liquid discharge control gate 605 is opened.

[0044] Subsequently, the first mixing drive mechanism 501 and the second mixing drive mechanism 502 operate in opposite directions, and through the connecting piece 14, they drive the spiral mixing blades 15 to form a counter-current, so that the soil and the solidified slurry are fully mixed and reacted.

[0045] During construction, the material can be discharged as needed through the spray valve 701 of the material supply pool 7, and the material properties can be precisely controlled. The fluidized solidified soil after mixing meets the standards is finally discharged through the discharge gate 504, completing the integrated continuous construction operation.

[0046] In summary, this equipment integrates screening and impurity removal, crushing and homogenizing, conveying and feeding, liquid premixing, bidirectional stirring, and auxiliary material replenishment. It improves the accuracy of material pretreatment by relying on the adjustable tilting screening structure, simplifies the equipment layout by gravity self-flow structure, and ensures the quality of finished products by reverse convection stirring. It has a high degree of integration and strong mobility, and can fully adapt to the continuous and mobile construction needs of the construction site.

[0047] The above specific embodiments are merely several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
