Abstract
Description
Technical Field
[0001] This utility model relates to a soybean urease purification device suitable for construction sites, and belongs to the field of civil engineering technology. Background Technology
[0002] Enzyme-induced calcium carbonate precipitation (EICP) technology can cement loose soil into a stone-like mass with a certain strength. Due to its environmental friendliness, simple reaction mechanism and reactants, and controllable process, it has broad application prospects in the reinforcement of poor soil. EICP soil solidification tests typically employ a circulating grouting method, in which urease solution and cementing fluid are circulated into the soil to induce calcium carbonate precipitation and continuous growth between soil particles. The generated calcium carbonate not only fills soil pores but also acts as a "bridge," connecting loose minerals together, provided that large-volume calcium carbonate crystals are cemented with two or more soil particles.
[0003] Urease solution provides a large amount of urease in the reaction, acting as a catalyst and increasing the hydrolysis rate of urea by tens of thousands of times. Therefore, the preparation of urease solution is a crucial step in EICP technology. However, one of the biggest problems currently facing the on-site preparation of soybean urease is that when using only water to extract urease, the supernatant often has high turbidity and contains a large amount of soybean flour suspension. Although these suspensions can also play a catalytic role in promoting the decomposition of urea, they often clog the pores between soil particles, preventing the subsequent formation of calcium carbonate in the pores and affecting the final reinforcement effect. Therefore, a soybean urease purification device suitable for construction sites is needed to solve the above-mentioned technical problems. Utility Model Content

[0028] like Figures 1-4 As shown, this embodiment provides a soybean urease purification device suitable for construction sites, including a fixed outer barrel 3 with a drain pipe 2 equipped with an electromagnetic valve 1 connected to the bottom of the barrel. The fixed outer barrel has a rotating inner barrel 5 driven by a motor 4 inside. The rotating inner barrel has several water-permeable holes 6 around its periphery and a filter bag 7 inside. The filter bag is driven by a driving mechanism to revolve and rotate within the rotating inner barrel.
[0029] In this embodiment of the utility model, the openings of both the fixed outer barrel and the rotating inner barrel face upwards, and the opening of the filter bag faces upwards and is provided with a zipper 8.
[0030] In this embodiment of the utility model, the bottom of the fixed outer barrel is fixed on the support frame 9.
[0031] In this embodiment of the utility model, the rotating inner tub and the fixed outer tub are coaxial. The motor is installed at the bottom of the fixed outer tub, and its motor output shaft 10 passes through the bottom of the fixed outer tub and is fixedly connected to the bottom of the outer tub of the rotating inner tub. A circular support ring plate 11 is coaxially fixed on the bottom of the inner tub of the fixed outer tub, and a circular annular groove 12 for embedding the top edge of the support ring plate is coaxially provided on the bottom of the outer tub of the rotating inner tub.
[0032] In this embodiment of the present invention, a circular plate 13 is coaxially fixed on the top inner wall of the rotating inner barrel. A circular through hole 14 is opened on the surface of the circular plate near the circumference. A hollow notch 15 is opened on the surface of the circular plate next to the circular through hole. The hollow notch design allows the liquid falling above the circular plate to fall back into the interior of the rotating inner barrel through the hollow notch under centrifugal force. The filter bag is located in the circular through hole.
[0033] In this embodiment of the invention, the driving mechanism includes a rotating ring 16 coaxially mounted in a circular through hole. Several vertical positioning pins 17 are evenly distributed around the upper surface of the rotating ring. A rigid connecting ring 18 is fixed to the upper outer periphery of the filter bag. Several positioning pin holes 19, corresponding one-to-one with the positioning pins, are evenly distributed around the connecting ring. After the filter bag body passes through the rotating ring from top to bottom, the connecting ring supports it on the top surface of the rotating ring, with the positioning pins correspondingly embedded in the positioning pin holes. This allows the filter bag opening to be fully opened, facilitating the pouring of the upper clear liquid.
[0034] In this embodiment of the utility model, an outer gear ring 20 is fixedly provided on the outer circumference of the rotating ring, and an inner gear ring 21 coaxial with the rotating inner barrel is provided above the circular plate. The outer gear ring and the inner gear ring mesh with each other, wherein the inner gear ring is fixedly connected to the fixed outer barrel.
[0035] In this embodiment of the utility model, several L-shaped adapter rods 22 are uniformly fixed on the circumference of the end side of the internal gear ring. The other end of each adapter rod extends from the top of the rotating inner barrel to the outside and is fixedly connected to the inner wall of the fixed outer barrel.
[0036] In this embodiment of the utility model, a cover 23 is provided on the top opening of the filter bag, and a zipper is provided between the cover and the opening of the bag.
[0037] In this embodiment of the utility model, the filter bag is made of gauze with a mesh size of 200 mesh, 250 mesh, 300 mesh, 350 mesh, 400 mesh, 450 mesh, or 500 mesh.
[0038] Filter bags can be selected with different mesh sizes depending on the working conditions. When the soil pores are large and the grouting pressure is high, the pores are not easily blocked by soybean powder suspensions. In this case, a lower mesh size filter bag can be selected to improve the purification efficiency by sacrificing some purity. When the soil pores are small, they are more easily blocked by soybean powder suspensions during grouting. In this case, a higher mesh size filter bag should be selected to ensure the purity of the urease solution.
[0039] In this embodiment of the invention, the working principle of the soybean urease purification device suitable for construction sites is as follows:
[0040] Before using the device, crude urease should be extracted first. The operator should first mix soybean flour (crushed soybeans that meet the requirements) and purified water in a sedimentation tank at a material-to-liquid ratio of 1:10 to 1:20, and then let the sedimentation tank containing the soybean flour solution stand for 24 hours.
[0041] When using the device, the filter bag is placed in the rotating inner barrel with the top of the filter bag open. After the soybean flour solution has settled for the required time, the clear liquid that has separated into layers in the sedimentation tank is removed and poured into the filter bag, which is then sealed with a zipper. The rotating inner barrel begins to rotate, and the circular plate rotates along with it. As the filter bag revolves, its outer toothed ring engages with the fixed inner toothed ring, achieving both revolution and rotation of the filter bag. This generates centrifugal force, and the purified liquid flows from the filter bag into the interior of the rotating inner barrel, and then out through the drain pipe. The liquid flowing out of the drain pipe is the purified crude soybean urease solution.
[0042] This device is simple in structure and operation, easy to transport, and convenient for on-site preparation of urease solution. It enables large-scale purification and preparation of urease solution on-site, facilitating the purification of urease solution with good and efficient centrifugal purification.
[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
