Description

Technical Field

[0001] This invention relates to the field of microbial brick-making technology, specifically to a brick-making device that utilizes microorganisms to solidify coral reef sand. Background Technology

[0002] For my country's large-scale island and reef construction projects, utilizing microbial technology to solidify locally available coral sand and prepare microbially solidified coral sand bricks for use in island and reef construction not only avoids the long-distance, large-scale transportation of building materials from the mainland but also meets the requirements of "green engineering and ecological island and reef construction." However, there are currently few research reports on the use of microbial technology for brick making, and the related preparation processes are still immature. By isolating or screening microbial strains and repeating the microbial domestication and cultivation process of liquid culture-solid culture-screening-liquid culture, urease-producing bacteria suitable for the marine environment of islands and reefs can be cultivated. The ability of urease-producing bacteria to decompose urea and precipitate inorganic minerals in the marine environment of islands and reefs can be studied. Further domestication and cultivation optimization of the screened bacteria can be achieved by adjusting parameters such as culture medium formula, culture time, and rotation speed. For example, in the preparation method and apparatus of microbial coral sand bricks with application number CN201510836453.2, in the above technical solution, natural coral reefs are not all concentrated in one place, and some beaches and cliffs are not suitable for transportation. It is necessary to transport legally exploitable coral reefs to the processing site. Only by adding equipment along the coral reef group and processing locally can coral bricks be easily made. However, locally sourced coral reefs are too large to be directly made into bricks, and the existing equipment has too low brick-making efficiency. Summary of the Invention

[0025] This invention provides a brick-making device that utilizes microorganisms to solidify coral reef sand. It has the following beneficial effects:

[0026] (1) In this invention, corals mined in shallow sea areas are directly sent to the crushing and grinding components via a coral conveyor belt. Then, the corals are connected to the sand-to-solidification box via a reef sand conveyor belt and connected to the power supply. The drive motor drives the material collection and conveying components and links the crushing and grinding components to process the coral raw materials. The coral reef sand is sent to the sand-to-solidification box to support the sand bricks via the reef sand conveyor belt, which is convenient and fast.

[0027] (2) When the nearby mined coral raw materials are processed, since the new raw materials have not yet been mined, the material is moved to another mining point by the moving track at the lower end of the track moving base, and then connected to the sand transfer solidification box again, and connected to the coral conveyor belt for rapid processing into bricks. The bricks are then stacked, transported and dried for storage, which is more convenient.

[0028] (3) In this invention, the drive motor is connected to the drive gearbox, and the motor drive bevel gear at the inner end is driven to rotate through the motor extension shaft, thereby meshing the main shaft bevel gear to drive the upper agitation drive shaft to rotate. When the agitation drive shaft rotates, the inner plate mounting shaft of the outer mesh drives the inner partition mesh of the material to rotate, and drives the outer partition mesh outer plate to rotate.

[0029] (4) The present invention, through the above-mentioned rotation, allows the reef sand falling from above the agitator drive shaft to temporarily accumulate in the inner mesh of the accumulation material, and through the agitation of the inner mesh plate on the shaft, the reef sand moves outward to prevent blockage of the upper discharge. When the material accumulates, it will overflow the inner mesh of the accumulation material, and then be pushed by the outer mesh plate to fall into the inner groove discharge hole, and then be transported out by the reef sand conveyor belt installed in the reef sand discharge tunnel, thus achieving the effect of preventing material accumulation. When the material processing is finished, the remaining material can also be processed by removing the mesh on the inner mesh of the accumulation material.

[0030] (5) The present invention drives the upper grinding drive shaft to rotate synchronously by stirring the drive shaft, so that the upper main shaft ratchet rotates. While rotating, it pushes the upper cone ratchet to bounce up and down. By crushing the weight of the cone itself, the coral reef entering the raw material feed trough is crushed and slid into the lower grinding shell through the crushing bottom liner. Then, it enters the grinding feed trough and is continuously ground by the lower end of the grinding table, making the coral reef finer and thus making the produced reef bricks more compact.

[0031] (6) Through the above processing, the raw coral reef can be made more refined. By rotating the main shaft ratchet, under the restriction of the limiting slide, the crushing cone is pushed up and down by the ratchet of the cone to smash and crush the raw coral reef. This makes the overall drive structure of the equipment simpler and easier to move between mining points. Attached Figure Description

[0047] like Figures 1 to 2As shown in the figure, this invention provides a brick-making device for solidifying coral reef sand using microorganisms, including a track-moving base 1, a material accumulation and conveying component 3, and a crushing and grinding component 5. A base mounting plate 2 is fixedly installed on the upper surface of the track-moving base 1.

Processing support columns 4 are fixedly installed at the four corners of the upper surface of the base mounting plate 2. The crushing and grinding component 5 is fixedly installed on the upper end of the processing support columns 4. A reef sand conveyor belt 8 is provided on one side of the material accumulation and conveying component 3 and located on the upper surface of the track-moving base 1. A sand-to-solidification box 9 is fitted to the outer end of the sand-to-solidification box 9. A material feeding bin 10 is provided at the outer end of the sand-to-solidification box 9. A moving track 6 is laid under the track-moving base 1. Several movable track sleepers 7 are laid at the lower end of the movable track 6. A raw material conveyor belt support column 14 is set on one side of the movable track 6. A coral conveyor belt 15 is set on the raw material conveyor belt support column 14. A motor mounting plate 11 is fixedly installed on the upper surface of the track movable base 1 and on the side of the material accumulation and conveying component 3. A drive motor 12 is fixedly installed on the upper end of the motor mounting plate 11. A drive reduction gearbox 13 is set on one side of the output end of the drive motor 12. When the nearby mined coral raw materials are processed, since the new raw materials have not yet been mined, they are moved to another mining point through the movable track 6 at the lower end of the track movable base 1, and reconnected to the sand transfer and solidification box 9, and connected to the coral conveyor belt 15 for rapid processing into bricks. The bricks are then stacked, transferred and dried for storage, which is more convenient.

[0048] In the above technical solution, corals mined in the shallow sea area are directly sent to the crushing and grinding component 5 via the coral conveyor belt 15. Then, they are connected to the sand-to-solidification box 9 via the reef sand conveyor belt 8 and connected to the power supply. The drive motor 12 drives the material collection and conveying component 3 and links it with the crushing and grinding component 5 to process the coral raw materials. The coral reef sand is then sent to the sand-to-solidification box 9 to support the sand bricks via the reef sand conveyor belt 8, which is convenient and fast.

[0049] like Figure 1 , Figures 3 to 5As shown, the material collection and conveying assembly 3 includes: a reef sand collection bin 301, an extension connecting groove 302, an inner collection groove 303, a stirring drive shaft 304, an inner mesh plate mounting shaft 305, an inner mesh plate 306, an inner collection mesh 307, an outer mesh plate 308, a reef sand discharge tunnel 309, and an inner groove discharge hole 311. The reef sand collection bin 301 is mounted on the upper surface of the base plate 2. The inner collection groove 303 is formed inside the reef sand collection bin 301. The stirring drive shaft 304 is rotatably mounted in the middle of the inner collection groove 303. The side is provided with several inner mesh plate mounting shafts 305, and inner mesh plates 306 are provided on the inner mesh plate mounting shafts 305; an inner mesh for material accumulation 307 is provided at the outer end of the inner mesh plate mounting shafts 305, and several outer mesh plates 308 are provided at the outer end of the inner mesh for material accumulation 307; expansion connection grooves 302 are opened on both sides of the reef sand accumulation bin 301; a reef sand discharge tunnel 309 is provided at the front end of the reef sand accumulation bin 301; an inner trough discharge hole 311 is opened at the bottom of the inner trough for material accumulation 303 and at the rear end of the reef sand discharge tunnel 309. An integrated transmission housing 312 is provided. A mesh-type material accumulation base plate 313 is fixedly installed on the upper end of the transmission housing 312 within the material accumulation trough 303. A main shaft bevel gear 314 is coaxially integrated on the lower end of the agitator drive shaft 304 within the transmission housing 312. A motor drive bevel gear 315 meshes with one side of the main shaft bevel gear 314. A motor extension shaft 316 is coaxially integrated to the rear end of the motor drive bevel gear 315. A motor connecting bushing 310 is sleeved on the motor extension shaft 316. Through the aforementioned rotation, the agitator drive shaft 304... 4. The reef sand falling from above can be temporarily accumulated in the inner partition 307 of the material accumulation area. It is stirred by the inner partition plate 306 on the inner partition plate mounting shaft 305, which moves the reef sand outward to prevent blockage of the upper discharge. When the material accumulates, it will overflow the inner partition 307 of the material accumulation area and be pushed by the outer partition plate 308 into the inner tank discharge hole 311. Then it will be transported out by the reef sand conveyor belt 8 installed in the reef sand discharge tunnel 309, thus achieving the effect of preventing material accumulation. When the material processing is finished, the remaining material can be processed by removing the partition on the inner partition 307 of the material accumulation area.

[0050] In the above technical solution, the drive motor 12 is connected to the drive reduction gearbox 13, and the inner end of the motor drive bevel gear 315 is driven to rotate through the motor extension shaft 316, thereby engaging the main shaft bevel gear 314 to drive the upper end of the stirring drive shaft 304 to rotate. When the stirring drive shaft 304 rotates, the outer inner plate mounting shaft 305 drives the inner partition mesh 307 of the material accumulation to rotate, and drives the outer outer partition mesh outer plate 308 to rotate.

[0051] like Figure 1 , Figures 7 to 8As shown, the crushing and grinding assembly 5 includes: a supporting side beam 501, a lifting frame 502, a limiting sliding liner 503, a crushing cone 504, a raw material feed chute 505, a crushing sound-absorbing shell 506, a sound-absorbing shell base plate 507, an outwardly expanding grinding table 509, and a crushing bottom liner 512; the supporting side beam 501 is fixedly installed inside the processing support column 4, and the supporting side beam 501 has an integrally formed lifting frame 502 in the middle, with a [missing information - likely a type of frame or material] on the inner wall of the lifting frame 502. A limiting slide liner 503 is provided, within which a crushing cone 504 is slidably disposed. The crushing cone 504 has several raw material feed troughs 505. A ratchet tooth 516 is integrally provided at the lower end of the crushing cone 504. A crushing sound-absorbing shell 506 is fixedly installed at the lower end of the lifting frame 502. A sound-absorbing shell base plate 507 is fixedly installed at the lower end of the crushing sound-absorbing shell 506. A crushing bottom liner 512 is fixedly installed within the sound-absorbing shell base plate 507. A grinding shell 508 is fixedly installed at the lower end of the sound-absorbing shell base plate 507. An extended grinding table 509 is fixedly installed at the lower end of the grinding shell 508. A reef sand hopper 510 is fixedly installed at the lower end of the extended grinding table 509. A grinding drive shaft 511 is rotatably arranged in the middle of the reef sand hopper 510. A grinding table 513 is coaxially arranged on the grinding drive shaft 511 and located inside the grinding shell 508. A grinding feed groove 514 is opened in the middle of the grinding table 513. The upper end of the grinding drive shaft 511 is integrally provided with a main shaft ratchet 515, which is configured to cooperate with the upper conical ratchet 516. Through the above processing, the raw coral reef can be made more refined. By rotating the main shaft ratchet 515, under the restriction of the limiting sliding bushing 503, the crushing cone 504 is pushed up and down by the cone ratchet 516 to smash and crush the raw coral reef, making the overall drive structure of the equipment simpler and facilitating movement between mining points.

[0052] In the above technical solution, the grinding drive shaft 511 at the upper end is synchronously driven to rotate by the stirring drive shaft 304, which causes the main spindle ratchet 515 at the upper end to rotate. At the same time, the ratchet 516 at the upper end is pushed to move up and down. By crushing the weight of the ratchet 504 itself, the coral reef entering the raw material feed trough 505 is crushed and slid into the grinding shell 508 at the lower end through the crushing bottom liner 512. Then, it enters the grinding feed trough 514 and is continuously ground by the lower end of the grinding table 513, making the coral reef finer and thus making the produced reef bricks more compact.

[0053] like Figure 1 , Figures 9 to 13As shown, the sand-to-solidification box 9 includes: a solidification box body 901, a reef sand feeding trough 902, a brick mold feeding trough 903, a discharge hole 904, a sand brick processing tunnel 905, a lifting cylinder 906, a transfer box 907, a stirring motor 908, a stirring rod 909, a microbial adhesive conveying pipe 915, and an adhesive spray nozzle 916. The solidification box body 901 is located at one end of the reef sand conveyor belt 8. The front end of the solidification box body 901 has a reef sand feeding trough 902. A brick mold feeding trough 903 is fixedly connected to one side of the solidification box body 901. A discharge hole 904 is opened on the other side of the solidification box body 901. The sand brick processing tunnel 905 is fixedly installed inside the solidification box body 901 and behind the reef sand feeding trough 902. Two lifting cylinders 906 are fixedly installed on the upper inner wall of the sand brick processing tunnel 905. A transfer box 906 is fixedly installed below the output end of the lifting cylinder 906. The moving box 907 has a stirring motor 908 fixedly installed on its upper surface and two stirring rods 909 rotatably installed on its lower end. A microbial adhesive conveying pipe 915 is also installed on the sand brick processing tunnel 905. Several adhesive nozzles 916 are installed on a section of the microbial adhesive conveying pipe 915 located inside the sand brick processing tunnel 905. A first brick mold conveyor belt 912 is installed inside the brick mold feeding trough 903. A second brick mold conveyor belt 913 is installed below the sand brick processing tunnel 905. A third brick mold conveyor belt 914 is installed between the discharge hole 904 and the sand brick processing tunnel 905. A transfer cylinder 910 is fixedly installed on the inner wall of the curing box 901 near the brick mold feeding trough 903 and at the end of the second brick mold conveyor belt 913. A transfer push plate 911 is fixedly installed on the output end of the transfer cylinder 910.

[0054] In the above technical solution, the reef sand transported by the reef sand conveyor belt 8 enters the reef sand feed trough 902 and falls into the brick mold that is transported in by the first brick mold conveyor belt 912 from the brick mold feed trough 903 on one side. The mixed microbial adhesive is sprayed into the brick mold through the adhesive nozzle 916 at the lower end of the microbial adhesive conveying pipe 915. Then, it is transported to the area directly below the stirring rod 909 by the second brick mold conveyor belt 913. The lifting cylinder 906 and the stirring motor 908 are started to make the stirring rod 909 stir the reef sand and microbial adhesive at a uniform speed in the brick mold. Then, the transfer cylinder 910 is started to push the brick mold to the third brick mold conveyor belt 914 through the transfer push plate 911 at the front end and transfer it to one side for static curing.

[0055] The microbial adhesive is prepared by adding water to Bacillus Pasteurella multocida, which has been domesticated and preserved, to form a bacterial solution with an activity greater than 1 mM·min⁻¹. The pH is adjusted to 7-8, and then mixed with calcium chloride and urea solutions with a concentration of 1 mol·L⁻¹. Finally, the mixture is passed into a mold and reacted for 3 hours in each of the two opposite current directions under a voltage of 3-4V. The mixed solution after the reaction is discharged, and this step is repeated 6-8 times. After demolding, the mixture is dried to obtain coral sand bricks.

[0056] Working principle:

[0057] This invention allows corals harvested from shallow sea areas to be directly fed into the crushing and grinding assembly 5 via a coral conveyor belt 15. Subsequently, the corals are connected to the sand-to-solidification box 9 via a reef sand conveyor belt 8 and connected to a power source. This enables the drive motor 12 to drive the material accumulation and conveying assembly 3 and, in conjunction with the crushing and grinding assembly 5, process the coral raw materials. The coral reef sand is then transported to the sand-to-solidification box 9 via the reef sand conveyor belt 8 to support the sand bricks, making the process convenient and fast.

[0058] After the nearby harvested coral raw materials are processed, since new raw materials have not yet been harvested, they are moved to another mining point via the moving track 6 at the lower end of the track moving base 1, and then connected to the sand-to-solidification box 9 again, and connected to the coral conveyor belt 15 for rapid processing into bricks. The bricks are then stacked, transported and dried for storage, which is more convenient.

[0059] The drive motor 12 is connected to the drive reduction gearbox 13, and the motor extension shaft 316 drives the inner end of the motor drive bevel gear 315 to rotate, thereby meshing the main shaft bevel gear 314 to drive the upper end of the agitation drive shaft 304 to rotate. When the agitation drive shaft 304 rotates, the outer mesh inner plate mounting shaft 305 drives the material accumulation inner partition mesh 307 to rotate, and drives the outer partition mesh outer plate 308 to rotate.

[0060] Through the aforementioned rotation, the reef sand falling from above the agitator drive shaft 304 can temporarily accumulate in the inner accumulator mesh 307. The inner accumulator mesh 306 on the inner accumulator mesh mounting shaft 305 agitates the reef sand, causing it to move outward and preventing blockage of the upper discharge. When the material accumulates, it will overflow from the inner accumulator mesh 307 and be pushed by the outer accumulator mesh 308, falling into the inner trough discharge hole 311. It will then be transported out by the reef sand conveyor belt 8 installed in the reef sand discharge tunnel 309, thus achieving the effect of preventing material accumulation. When the material processing is finished, the remaining material can be processed by removing the mesh on the inner accumulator mesh 307.

[0061] The agitation drive shaft 304 synchronously drives the upper grinding drive shaft 511 to rotate, causing the upper main shaft ratchet 515 to rotate. While rotating, the upper conical ratchet 516 is pushed to bounce up and down. By crushing the weight of the conical 504 itself, the coral reef entering the raw material feed trough 505 is crushed and slid into the lower grinding shell 508 through the crushing bottom liner plate 512. Then, it enters the grinding feed trough 514 and is continuously ground by the lower end of the grinding table 513, making the coral reef finer and thus making the produced reef bricks more compact.

[0062] Through the above processing, the raw coral reef can be made more refined. By rotating the main shaft ratchet 515, under the restriction of the limiting sliding liner 503, the crushing cone 504 is pushed up and down by the cone ratchet 516 to smash and crush the raw coral reef, making the overall drive structure of the equipment simpler and easier to move between mining points.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
