Description

Technical Field

[0001] The invention relates to the technical field of liquid solidified soil backfill preparation, and in particular to a liquid solidified soil backfill preparation device and a preparation method thereof. Background Art

[0002] In the field of civil engineering and foundation treatment, liquid solidified soil backfill agent is a new type of foundation reinforcement material, which is favored due to its high strength, good stability and fast curing speed. However, there are many technical difficulties in the preparation process of traditional liquid solidified soil backfill agent, which affects the quality and performance of the product.

[0003] Referring to the Chinese invention patent, the publication number is: CN221912597U, and the name is: A liquid backfill material preparation device, including a water storage tank, a material storage tank, a pulverizer and a mixer. The mixer includes a mixing tank and a mixing body, and the mixing tank is connected to the water storage tank, the material storage tank and the pulverizer. When in use, the pulverizer crushes the stones and the like in the slag into fine slag, and the crushed slag is transported to the mixing tank. At the same time, the water stored in the water storage tank enters the mixing tank, and the curing agent stored in the material storage tank enters the mixing tank. Then, the mixing body stirs the slag, water and curing agent in the mixing tank, so that the slag, water and curing agent in the mixing tank are fully mixed and evenly mixed to form liquid backfill material. By setting up the pulverizer, the pulverizer can crush the stones and the like in the slag, which is conducive to fully mixing the slag, curing agent and water, and at the same time can avoid clogging of the liquid backfill material preparation device and extend the service life.

[0004] However, there are still some problems in actual use:

[0005] 1. First, for example, the above-mentioned traditional liquid solidified soil backfill agent preparation device often directly mixes the slag, water and curing agent together for stirring. This mixing method is prone to cause problems of local uneven concentration or insufficient mixing, thereby affecting the strength and stability of the liquid solidified soil backfill agent. Specifically, due to the large differences in the physical and chemical properties of the slag, water and curing agent, it is difficult to form a uniform mixture when directly mixed, resulting in large fluctuations in the performance of the prepared liquid solidified soil backfill agent.

[0006] 2. Secondly, for example, the above-mentioned traditional liquid solidified soil backfill agent preparation device uses a single stirring method for mixing. The single stirring method often leads to a lack of sufficient disturbance and shear force during the stirring process. The fluid dynamics effect during the stirring process has an important influence on the mixing effect, and the traditional single stirring method often cannot produce sufficient disturbance and shear force to break the agglomeration of particles or molecules in the fluid, thereby limiting the improvement of mixing uniformity. At the same time, the lack of dynamic effects such as eddy currents also leads to a slow circulation and exchange speed of materials in the mixing barrel, further affecting the mixing efficiency.

[0007] In view of the above problems, the present invention document proposes a device and method for preparing a liquid solidified soil backfill agent. Summary of the invention

[0008] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a liquid solidified soil backfill preparation device and a preparation method thereof, which allow the mixture of water and solidifying agent to enter the mixing barrel more evenly, thereby quickly and comprehensively mixing with the slag, so that the prepared liquid solidified soil backfill has higher strength and stability.

[0009] In order to achieve the above object, the present invention adopts the following technical solutions:

[0012] The discharge structure includes a rotating gear fixedly connected to the bottom of the second stirring shaft, and a rotating ring rotatably connected to the inside of the stirring barrel, the rotating ring is provided with a plurality of teeth, and the rotating gear and the teeth on the rotating ring are meshed with each other, a feeding circular tube is fixedly connected to the bottom of the rotating ring, and a plurality of discharge pipes are provided at the bottom of the feeding circular tube.

[0013] Preferably, a grinding cover is fixedly connected to the top of the inner wall of the mixing barrel, and a feeding cylinder is connected to the top of the mixing barrel.

[0014] Preferably, the stirring structure includes a motor installed at the bottom of the stirring barrel, the output end of the motor is fixedly connected to a first stirring shaft, the first stirring shaft is rotatably connected to the inside of the stirring barrel, and the outer wall of the first stirring shaft is fixedly connected to a grinding roller and a plurality of first stirring blades, and the grinding roller is located inside the grinding cover.

[0015] Preferably, the auxiliary structure comprises a mounting plate fixedly connected to the bottom of the rotating ring, a plurality of vertical plates are fixedly connected to the bottom of the mounting plate, and a plurality of stirring blades are fixedly connected to the vertical plates.

[0016] Preferably, a plurality of balls are rotatably connected to the bottom of the rotating ring, and all of the balls are rollingly connected to the mixing barrel.

[0017] Preferably, the connecting structure includes two connecting steel pipes connected to the bottom of the mixing barrel, and the discharge port of the connecting steel pipe is connected to a connecting hose, and the connecting hose is connected to the supply circular pipe, so that the water and curing agent mixed inside the mixing barrel can enter the supply circular pipe through the connecting steel pipe and the connecting hose, and then be discharged into the mixing barrel through the discharge pipe.

[0018] Preferably, the driving structure includes a first driving block fixedly connected to the outer wall of the top of the first stirring shaft, and a second driving block fixedly connected to the outside of the top of the second stirring shaft, a push plate being rotatably connected to the first driving block, and an end of the push plate away from the first driving block is rotatably connected to the second driving block.

[0019] Preferably, the first driving block, the second driving block and the pushing plate are all located at the top of the stirring barrel, and when the motor drives the first driving block to rotate through the first stirring shaft, the pushing plate drives the second stirring shaft to perform alternating forward and reverse rotational motion through the second driving block.

[0020] Preferably, a shielding plate is fixedly connected to the bottom of the grinding cover, and the shielding plate is in contact with the inner wall of the mounting plate.

[0021] The method for preparing the liquid solidified soil backfilling agent preparation device comprises the following steps:

[0022] S1. When the operator needs to use the device to prepare liquid solidified soil backfill, first connect the two feed pipes to the external feed assembly respectively, so that the external feed assembly transfers water and solidifying agent to the mixing barrel through the two feed pipes, and at the same time guides the slag into the grinding cover through the feed cylinder;

[0023] S2. The operator turns on the motor, and the motor drives the grinding roller and the first stirring blade to rotate through the first stirring shaft. After the slag enters the grinding cover through the feeding tube, the grinding roller rotates inside the grinding cover, so that the grinding cover and the grinding roller cooperate with each other to crush the slag inside. The crushed slag is directly transferred downward and falls into the mixing barrel;

[0024] S3. When the motor drives the first stirring shaft to rotate, the push plate drives the second stirring shaft to rotate in a positive and negative alternating manner under the cooperation of the first driving block and the second driving block. When the second stirring shaft drives the second stirring blade to rotate, the water and curing agent entering the mixing barrel can be stirred and mixed. The water and curing agent after stirring and mixing enter the feeding circular tube through two connecting steel pipes and two connecting hoses. Since the rotating gear and the second stirring shaft rotate synchronously, the rotating gear drives the rotating ring, the feeding circular tube and the mounting plate to rotate in a positive and negative alternating manner at the same time. When the feeding circular tube rotates in a positive and negative alternating manner, the water and curing agent mixed in the feeding circular tube are discharged into the mixing barrel through the discharge pipe.

[0025] S4. When the mounting plate rotates alternately forward and reverse inside the mixing barrel, all the stirring blades are driven to move synchronously through the vertical plate. At this time, the motor drives the grinding roller to rotate rapidly through the first stirring shaft, so that the grinding roller and the stirring blades stir and mix the water, curing agent and slag inside the mixing barrel, thereby preparing liquid cured soil backfill agent. Finally, the liquid cured soil backfill agent can be discharged through the discharge port at the bottom of the mixing barrel.

[0026] Compared with the prior art, the present invention provides a device for preparing a liquid solidified soil backfill agent, which has the following beneficial effects:

[0027] 1. The liquid solidified soil backfill preparation device is provided with a mixing structure and a discharge structure. When an operator uses the device to prepare the liquid solidified soil backfill, the operator turns on the stirring structure, and with the cooperation of the driving structure, the second stirring shaft drives the second stirring blade to perform a positive and negative alternating rotational motion. After the external feeding component introduces water and the curing agent into the mixing barrel, the second stirring blade rotates inside the mixing barrel to stir and mix the water and the curing agent in the mixing barrel in advance. The pre-mixing of water and curing agent can ensure that the two have a preliminary interaction at the chemical level to form a more uniform mixture. In addition, due to the cooperation of the rotating gear and the rotating ring, the feeding tube and the discharge tube simultaneously perform a positive and negative alternating rotational motion, so that the mixture of water and curing agent enters the mixing barrel more evenly, thereby quickly and comprehensively mixing with the slag, avoiding the problem of local uneven concentration or insufficient mixing caused by direct mixing of the three raw materials, so that the prepared liquid solidified soil backfill has higher strength and stability.

[0028] 2. The liquid solidified soil backfill preparation device is provided with a stirring structure and an auxiliary structure. The motor drives the grinding roller and the first stirring blade to rotate through the first stirring shaft. After the slag enters the grinding cover through the feed barrel, the grinding roller rotates inside the grinding cover, so that the grinding cover and the grinding roller cooperate with each other to crush the slag inside. This process not only effectively reduces the particle size of the slag, but also increases its surface area, laying a solid foundation for the subsequent full reaction with the curing agent, thereby ensuring the excellent performance of the prepared liquid solidified soil backfill in terms of strength, stability and curing speed. At the same time, the first stirring shaft drives the first stirring blade to rotate while also driving the mounting plate to rotate through the driving structure. The vertical plate and the stirring blade on the mounting plate are cleverly designed to rotate in both positive and negative directions inside the mixing barrel. This unique motion mode not only enhances the fluid dynamics effect in the mixing barrel, but also the positive and negative alternating rotation of the stirring blade introduces strong disturbance, breaking the stable fluid flow pattern generated by the first stirring blade. This disturbance causes the fluid flow inside the mixing barrel to become more complicated and chaotic, which helps to break the agglomeration of particles or molecules in the fluid and significantly improves the uniformity of mixing. In addition, the positive and negative alternating rotation of the stirring blade also generates strong shear force and eddy current, which helps to cause mutual friction and collision between particles, further refines the particles and promotes their full contact and reaction with the curing agent. The eddy current helps to accelerate the circulation and exchange of materials in the mixing barrel, thereby improving the mixing efficiency. These dynamic effects work together to not only enhance the mixing effect, but also ensure the uniformity and density of the prepared liquid solidified soil backfill agent in microstructure.

[0029] 3. The liquid solidified soil backfill agent preparation device is provided with a mounting plate and a baffle plate. The mounting plate and the baffle plate cooperate with each other to play a certain shielding role, thereby preventing the water, curing agent and slag mixed inside the mixing barrel from splashing upward and affecting the rotational movement of the rotating gear and the rotating ring. Moreover, since the mounting plate is fixedly connected to the rotating ring and the baffle plate is fixedly connected to the bottom of the grinding cover, the mounting plate can rotate with the baffle plate, so that the mounting plate can normally drive the vertical plate to rotate, thereby ensuring the mixing effect of the stirring blade on the inside of the mixing barrel.

[0030] 4. The liquid solidified soil backfill preparation device is provided with balls, which can provide a certain support to the rotating ring and make the rotating ring rotate more smoothly inside the mixing barrel, thereby ensuring the preparation effect of the device on the liquid solidified soil backfill.

[0044] The mixing structure 3 includes a mixing barrel 301 fixedly connected to the top of the inner wall of the mixing barrel 1, a second stirring shaft 302 is rotatably connected inside the mixing barrel 301, a second stirring blade 303 is fixedly connected to the outer wall of the second stirring shaft 302, two feeding pipes 304 are connected to the side of the mixing barrel 301, and the two feeding pipes 304 are respectively connected to two external feeding components, so that the external feeding components transfer water and curing agent to the inside of the mixing barrel 301 through the two feeding pipes 304;

[0045] The discharge structure 4 includes a rotating gear 401 fixedly connected to the bottom of the second stirring shaft 302, and a rotating ring 402 rotatably connected to the inside of the stirring barrel 1, a plurality of teeth are arranged on the rotating ring 402, and the rotating gear 401 and the teeth on the rotating ring 402 are meshed with each other, a feeding circular tube 403 is fixedly connected to the bottom of the rotating ring 402, and a plurality of discharge pipes 404 are arranged at the bottom of the feeding circular tube 403.

[0046] In the present invention, a grinding cover 101 is fixedly connected to the top of the inner wall of the mixing barrel 1, and a feeding barrel 102 is connected to the top of the mixing barrel 1. The stirring structure 2 includes a motor 201 installed at the bottom of the mixing barrel 1, and the output end of the motor 201 is fixedly connected to a first stirring shaft 202, and the first stirring shaft 202 is rotatably connected to the inside of the mixing barrel 1. A grinding roller 203 and a plurality of first stirring blades 204 are fixedly connected to the outer wall of the first stirring shaft 202. The grinding roller 203 is located inside the grinding cover 101. By setting the grinding cover 1 01 and grinding roller 203, after the slag enters the grinding cover 101 through the feeding tube 102, the grinding roller 203 rotates inside the grinding cover 101, so that the grinding cover 101 and the grinding roller 203 cooperate with each other to crush the slag inside. This process not only effectively reduces the particle size of the slag, but also increases its surface area, laying a solid foundation for the subsequent full reaction with the curing agent, thereby ensuring the excellent performance of the prepared liquid solidified soil backfill agent in terms of strength, stability and curing speed.

[0047] In the present invention, the auxiliary structure 5 includes a mounting plate 501 fixedly connected to the bottom of the rotating ring 402, a plurality of vertical plates 502 are fixedly connected to the bottom of the mounting plate 501, and a plurality of stirring blades 503 are fixedly connected to the vertical plates 502. By providing the stirring blades 503, the first stirring shaft 202 drives the first stirring blade 204 to rotate, and also drives the mounting plate 501 to rotate through the driving structure 8. The vertical plates 502 and the stirring blades 503 on the mounting plate 501 are cleverly designed and can perform positive and negative alternating rotational motion inside the mixing barrel 1. This unique motion mode not only enhances the fluid dynamics effect in the mixing barrel, but also the positive and negative alternating rotation of the stirring blades 503 introduces strong disturbances. The stable fluid flow pattern generated by the first stirring blade 204 is disrupted. This disturbance causes the fluid flow inside the stirring barrel 1 to become more complex and chaotic, which helps to break the agglomeration of particles or molecules in the fluid and significantly improves the uniformity of mixing. In addition, the alternating forward and reverse rotation of the stirring blade 503 also generates strong shear force and eddy currents, which helps the mutual friction and collision between particles, further refines the particles and promotes their full contact and reaction with the curing agent. The eddy currents help to accelerate the circulation and exchange of materials in the stirring barrel, thereby improving the mixing efficiency. These kinetic effects work together to not only enhance the mixing effect, but also ensure the uniformity and density of the prepared liquid solidified soil backfill agent in terms of microstructure.

[0051] The discharge structure 4 includes a rotating gear 401 fixedly connected to the bottom of the second stirring shaft 302, and a rotating ring 402 rotatably connected to the inside of the stirring barrel 1, a plurality of teeth are arranged on the rotating ring 402, and the rotating gear 401 and the teeth on the rotating ring 402 are meshed with each other, a feeding circular tube 403 is fixedly connected to the bottom of the rotating ring 402, and a plurality of discharge pipes 404 are arranged at the bottom of the feeding circular tube 403.

[0052] In the present invention, a grinding cover 101 is fixedly connected to the top of the inner wall of the mixing barrel 1, and a feeding barrel 102 is connected to the top of the mixing barrel 1. The stirring structure 2 includes a motor 201 installed at the bottom of the mixing barrel 1, and the output end of the motor 201 is fixedly connected to a first stirring shaft 202, and the first stirring shaft 202 is rotatably connected to the inside of the mixing barrel 1. A grinding roller 203 and a plurality of first stirring blades 204 are fixedly connected to the outer wall of the first stirring shaft 202. The grinding roller 203 is located inside the grinding cover 101. By setting the grinding cover 1 01 and grinding roller 203, after the slag enters the grinding cover 101 through the feeding tube 102, the grinding roller 203 rotates inside the grinding cover 101, so that the grinding cover 101 and the grinding roller 203 cooperate with each other to crush the slag inside. This process not only effectively reduces the particle size of the slag, but also increases its surface area, laying a solid foundation for the subsequent full reaction with the curing agent, thereby ensuring the excellent performance of the prepared liquid solidified soil backfill agent in terms of strength, stability and curing speed.

[0053] In the present invention, the auxiliary structure 5 includes a mounting plate 501 fixedly connected to the bottom of the rotating ring 402, a plurality of vertical plates 502 are fixedly connected to the bottom of the mounting plate 501, and a plurality of stirring blades 503 are fixedly connected to the vertical plates 502. By providing the stirring blades 503, the first stirring shaft 202 drives the first stirring blade 204 to rotate, and also drives the mounting plate 501 to rotate through the driving structure 8. The vertical plates 502 and the stirring blades 503 on the mounting plate 501 are cleverly designed and can perform positive and negative alternating rotational motion inside the mixing barrel 1. This unique motion mode not only enhances the fluid dynamics effect in the mixing barrel, but also the positive and negative alternating rotation of the stirring blades 503 introduces strong disturbances. The stable fluid flow pattern generated by the first stirring blade 204 is disrupted. This disturbance causes the fluid flow inside the stirring barrel 1 to become more complex and chaotic, which helps to break the agglomeration of particles or molecules in the fluid and significantly improves the uniformity of mixing. In addition, the alternating forward and reverse rotation of the stirring blade 503 also generates strong shear force and eddy currents, which helps the mutual friction and collision between particles, further refines the particles and promotes their full contact and reaction with the curing agent. The eddy currents help to accelerate the circulation and exchange of materials in the stirring barrel, thereby improving the mixing efficiency. These kinetic effects work together to not only enhance the mixing effect, but also ensure the uniformity and density of the prepared liquid solidified soil backfill agent in terms of microstructure.

[0054] In the present invention, a plurality of balls 6 are rotatably connected to the bottom of the rotating ring 402, and all the balls 6 are rollingly connected to the mixing barrel 1. By setting the balls 6, the balls 6 can play a certain supporting role on the rotating ring 402, and make the rotating ring 402 rotate more smoothly inside the mixing barrel 1, thereby ensuring the preparation effect of the device on the liquid solidified soil backfill agent.

[0055] In the present invention, the driving structure 8 includes a first driving block 801 fixedly connected to the outer wall of the top of the first stirring shaft 202, and a second driving block 802 fixedly connected to the outside of the top of the second stirring shaft 302. The first driving block 801 is rotatably connected to a push plate 803, and one end of the push plate 803 away from the first driving block 801 is rotatably connected to the second driving block 802. The first driving block 801, the second driving block 802 and the pushing plate 803 are all located at the top of the stirring barrel 1. When the motor 201 drives the first driving block 801 to rotate through the first stirring shaft 202, the pushing plate 803 drives the second stirring shaft 302 to perform a positive and negative alternating rotational motion through the second driving block 802. By setting the driving structure 8, when the motor 201 drives the first stirring shaft 20 When the grinding roller 203 and the first stirring blade 204 are driven to rotate, the first driving block 801 can drive the push plate 803 and the second stirring shaft 302 to perform positive and negative alternating rotational motion through the second driving block 802. Under the action of the rotating gear 401, the rotating ring 402 drives the feeding tube 403 and the mounting plate 501 to perform positive and negative alternating rotational motion, so that the water and curing agent mixed in the feeding tube 403 can be evenly and comprehensively discharged into the mixing barrel 1, preliminarily ensuring the mixing effect of water, curing agent and slag, thereby ensuring the quality of the prepared liquid solidified soil backfill agent. In addition, since the mounting plate 501 drives the stirring blade 503 to perform positive and negative alternating rotational motion through the vertical plate 502, the linkage effect ensures the convenience of use of the device.

[0056] In the present invention, a baffle plate 9 is fixedly connected to the bottom of the grinding cover 101, and the baffle plate 9 is fitted with the inner wall of the mounting plate 501. By setting the mounting plate 501 and the baffle plate 9, the mounting plate 501 and the baffle plate 9 cooperate with each other to play a certain shielding role, thereby preventing the water, curing agent and slag mixed inside the mixing barrel 1 from splashing upward and affecting the rotational movement of the rotating gear 401 and the rotating ring 402. Moreover, since the mounting plate 501 is fixedly connected to the rotating ring 402, and the baffle plate 9 is fixedly connected to the bottom of the grinding cover 101, the mounting plate 501 can rotate with the baffle plate 9, so that the mounting plate 501 can normally drive the vertical plate 502 to rotate, thereby ensuring the mixing effect of the stirring blade 503 on the inside of the mixing barrel 1.

[0057] Working principle: When the operator needs to use the device to prepare liquid solidified soil backfill, first connect the two feed pipes 304 to the external feed assembly respectively, so that the external feed assembly transfers water and solidifying agent to the inside of the mixing barrel 301 through the two feed pipes 304, and at the same time, guides the slag into the grinding cover 101 through the feed cylinder 102;

[0058] The operator turns on the motor 201, and the motor 201 drives the grinding roller 203 and the first stirring blade 204 to rotate through the first stirring shaft 202. After the slag enters the grinding cover 101 through the feeding tube 102, the grinding roller 203 rotates inside the grinding cover 101, so that the grinding cover 101 and the grinding roller 203 cooperate with each other to crush the slag inside. The crushed slag is directly transferred downward and falls into the mixing barrel 1.

[0059] When the motor 201 drives the first stirring shaft 202 to rotate, under the cooperation of the first driving block 801 and the second driving block 802, the pushing plate 803 drives the second stirring shaft 302 to rotate alternately in forward and reverse directions. When the second stirring shaft 302 drives the second stirring blade 303 to rotate, the water and curing agent entering the mixing barrel 301 can be stirred and mixed. The water and curing agent after stirring and mixing enter the feeding circular tube 403 through the two connecting steel pipes 701 and the two connecting hoses 702. Since the rotating gear 401 and the second stirring shaft 302 perform synchronous rotational motion, the rotating gear 401 drives the rotating ring 402, the feeding circular tube 403 and the mounting plate 501 to also perform alternate rotational motion in forward and reverse directions at the same time. When the feeding circular tube 403 performs alternate rotational motion in forward and reverse directions, the water and curing agent mixed in the feeding circular tube 403 are discharged into the mixing barrel 1 through the discharge pipe 404.

[0060] When the mounting disc 501 performs alternating forward and reverse rotational motion inside the mixing barrel 1, all the stirring blades 503 are driven to perform synchronous motion via the vertical plate 502. At this time, since the motor 201 drives the grinding roller 203 to rotate rapidly via the first stirring shaft 202, the grinding roller 203 and the stirring blades 503 stir and mix the water, curing agent and slag inside the mixing barrel 1, thereby preparing liquid cured soil backfilling agent. Finally, the liquid cured soil backfilling agent can be discharged via the discharge port at the bottom of the mixing barrel 1.

[0061] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A method for preparing a liquid solidified soil backfill agent according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. When the operator needs to use the device to prepare liquid solidified soil backfilling agent, the two feed pipes (304) are first connected to the external feed assembly respectively, so that the external feed assembly transfers water and solidifying agent to the inside of the mixing barrel (301) through the two feed pipes (304), and at the same time, the slag is introduced into the inside of the grinding cover (101) through the feed cylinder (102); S2. The operator turns on the motor (201), and the motor (201) drives the grinding roller (203) and the first stirring blade (204) to rotate via the first stirring shaft (202). After the slag enters the grinding cover (101) through the feeding tube (102), the grinding roller (203) rotates inside the grinding cover (101), so that the grinding cover (101) and the grinding roller (203) cooperate with each other to crush the slag inside. The crushed slag is directly transferred downward and falls into the mixing barrel (1); S3, when the motor (201) drives the first stirring shaft (202) to rotate, under the cooperation of the first driving block (801) and the second driving block (802), the push plate (803) drives the second stirring shaft (302) to rotate in a positive and negative alternating manner, and when the second stirring shaft (302) drives the second stirring blade (303) to rotate, the water and curing agent entering the mixing barrel (301) can be stirred and mixed. The water and curing agent after the stirring and mixing process are passed through the two connecting steel pipes (701) and the two connecting steel pipes (702). The connecting hose (702) enters the interior of the feeding circular tube (403). Since the rotating gear (401) and the second stirring shaft (302) perform synchronous rotational motion, the rotating gear (401) drives the rotating ring (402), the feeding circular tube (403) and the mounting plate (501) to perform positive and negative rotational motions at the same time. When the feeding circular tube (403) performs positive and negative rotational motions, the water and curing agent mixed in the feeding circular tube (403) are discharged into the mixing barrel (1) through the discharge pipe (404). S4. When the mounting plate (501) performs a forward and reverse rotational motion inside the mixing barrel (1), all the stirring blades (503) are synchronously driven to perform a synchronous motion through the vertical plate (502). At this time, the motor (201) drives the grinding roller (203) to rotate rapidly through the first stirring shaft (202), so that the grinding roller (203) and the stirring blades (503) stir and mix the water, curing agent and slag inside the mixing barrel (1), thereby preparing a liquid curing soil backfill agent. Finally, the liquid curing soil backfill agent is discharged through the discharge port at the bottom of the mixing barrel (1).
