Description

Technical Field

[0001] This utility model belongs to the field of soil remediation technology, and in particular relates to a mixing and stirring device for lime remediation of soil. Background Technology

[0002] Currently, lime is widely used in the field of soil remediation as one of the methods of soil remediation. The common remediation method is to mix lime into the soil and eliminate acidic pollutants in the soil through acid-base neutralization. A mixing device is required when mixing.

[0003] The existing utility model with authorization announcement number CN216825734U discloses a mixing device for soil remediation, including a mixing tank, a support frame installed on the outside of the mixing tank, a drive motor installed on the support frame, a mixing shaft connected to the drive end of the drive motor, and the main body of the mixing shaft located inside the mixing tank.

[0004] The above technical solution involves arranging double-layered spiral blades on the mixing shaft. The inner spiral blades transport the soil mixture to the outside, while the outer spiral blades gather the soil mixture inward. Under the convective motion driven by the double spirals, the soil is agitated to the maximum extent within the box by the mixing blades, resulting in a more uniform mixture of soil and chemical agents and improved mixing efficiency. However, the above technical solution lacks the ability to automatically clean the mixing box and cannot remove residual material adhering to the inner wall of the mixing box. After the residual material dries, it will affect subsequent use and the accuracy of subsequent mixing, thus reducing the applicability of the mixing device for soil remediation.

[0005] Therefore, we propose a mixing and stirring device for lime remediation of soil to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem of the inability to automatically clean the inner wall of the mixing tank in the existing technology, and to propose a mixing and stirring device for lime remediation of soil.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mixing device for lime remediation of soil includes a mixing tank. Two electric telescopic rods are fixedly connected to the inner wall of the mixing tank. The telescopic ends of the two electric telescopic rods are fixedly connected to a scraper. A mixing shaft is rotatably connected inside the mixing tank. Pushing blades are fixedly connected to the bottom outer surface of the mixing shaft. A spray pipe is provided above the scraper. A water storage tank is fixedly connected to the outer surface of the mixing tank. A one-way valve is fixedly connected to the upper surface of the water storage tank. An auxiliary water pump is provided inside the water storage tank. A flexible water pipe is fixedly connected to the outlet of the auxiliary water pump. The flexible water pipe passes through the water storage tank and the mixing tank in sequence and is fixedly connected to the upper surface of the spray pipe.

[0009] Preferably, a support plate is fixedly connected to the outer surface of the mixing tank, and two sets of support legs are fixedly connected to the bottom surface of the support plate.

[0010] Preferably, an auxiliary bearing is fitted on the top outer surface of the stirring shaft, and the auxiliary bearing is embedded inside the stirring tank.

[0011] Preferably, a servo motor is fixedly connected to the top end of the stirring shaft, and stirring blades are fixedly connected to the outer surface of the stirring shaft.

[0012] Preferably, the outer surface of the mixing tank is fixedly connected to a feed pipe, and the inside of the feed pipe is movably hinged to a cover plate.

[0013] Preferably, the bottom surface of the nozzle is fixedly connected to four connecting posts, and the bottom end of each connecting post is fixedly connected to the upper surface of the scraper.

[0014] Preferably, a stabilizing block is fixedly connected to the outer surface of the auxiliary water pump, and the bottom surface of the stabilizing block is fixedly connected to the inner bottom wall of the water storage tank.

[0015] Preferably, a discharge pipe is fixedly connected to the bottom surface of the mixing tank, and a solenoid valve is fixedly connected to the outer surface of the discharge pipe.

[0016] In summary, the technical effects and advantages of this utility model are as follows:

[0017] Equipped with a mixing tank, electric telescopic rod, scraper, mixing shaft, pusher blades, spray pipe, water tank, one-way valve, auxiliary water pump, and flexible water pipe, the electric telescopic rod drives the scraper and spray pipe to move. The scraper, during movement, generates friction against the inner wall of the mixing tank, cleaning away any adhering residue. The mixing shaft and pusher blades also enhance the comprehensiveness of the scraping action. Simultaneously, the auxiliary water pump transmits water from the water tank to the spray pipe via the flexible water pipe, which then sprays it evenly onto the inner wall of the mixing tank, further cleaning the inner wall after scraping. This solves the problems of lacking automatic cleaning capabilities for the mixing tank, failing to remove adhering residue from the inner wall, and allowing the residue to dry and affect subsequent use and the accuracy of mixing. This improves the applicability of the mixing device for soil remediation. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4A mixing device for lime remediation of soil includes a mixing tank 1. Two electric telescopic rods 2 are fixedly connected to the inner wall of the mixing tank 1. A support plate 11 is fixedly connected to the outer surface of the mixing tank 1. Two sets of support legs 12 are fixedly connected to the bottom surface of the support plate 11. The support plate 11 and the support legs 12 work together to support the mixing tank 1 and increase the height of the mixing tank 1, thereby improving the convenience of use.

[0025] The two electric telescopic rods 2 are fixedly connected to scrapers 3 at their telescopic ends. The mixing tank 1 is rotatably connected to a mixing shaft 4. An auxiliary bearing 13 is fitted on the top outer surface of the mixing shaft 4. The auxiliary bearing 13 is embedded inside the mixing tank 1. The auxiliary bearing 13 can reduce the friction generated by the mixing shaft 4 when it rotates, making the mixing shaft 4 more sensitive when it rotates. At the same time, it can also reduce the wear rate of the mixing shaft 4 and increase the service life of the mixing shaft 4.

[0026] Pushing blades 5 are fixedly connected to the bottom outer surface of the mixing shaft 4, servo motor 14 is fixedly connected to the top of the mixing shaft 4, and mixing blades 15 are fixedly connected to the outer surface of the mixing shaft 4. The servo motor 14 provides power to the mixing shaft 4, thereby driving the mixing blades 15 to rotate, and then the mixing blades 15 are used to mix the soil and lime in the mixing box 1.

[0027] A spray pipe 6 is provided above the scraper 3. A feed pipe 16 is fixedly connected to the outer surface of the mixing tank 1. A cover plate 17 is movably hinged inside the feed pipe 16. The feed pipe 16 can provide a convenient feed port for the mixing tank 1, which increases the convenience when adding soil or lime into the mixing tank 1. The cover plate 17 can prevent materials from splashing out of the mixing tank 1.

[0028] A water storage tank 7 is fixedly connected to the outer surface of the mixing tank 1, and four connecting posts 18 are fixedly connected to the bottom surface of the spray pipe 6. The bottom end of each connecting post 18 is fixedly connected to the upper surface of the scraper 3. The connecting posts 18 can fix the spray pipe 6 and the scraper 3, so that the spray pipe 6 moves with the scraper 3, thereby improving the comprehensiveness of the spray pipe 6 when spraying water and improving the cleaning effect.

[0029] A one-way valve 8 is fixedly connected to the upper surface of the water storage tank 7. An auxiliary water pump 9 is installed inside the water storage tank 7. A stabilizing block 19 is fixedly connected to the outer surface of the auxiliary water pump 9. The bottom surface of the stabilizing block 19 is fixedly connected to the inner bottom wall of the water storage tank 7. The stabilizing block 19 can support the auxiliary water pump 9, effectively fix the position of the auxiliary water pump 9, prevent the auxiliary water pump 9 from moving in the mixing tank 1 during operation, and increase the stability of the device during operation.

[0030] The outlet of the auxiliary water pump 9 is fixedly connected to a soft water pipe 10. The soft water pipe 10 passes through the water storage tank 7 and the mixing tank 1 in sequence and is fixedly connected to the upper surface of the spray pipe 6. The bottom surface of the mixing tank 1 is fixedly connected to a discharge pipe 20. The outer surface of the discharge pipe 20 is fixedly connected to a solenoid valve 21. The discharge pipe 20 can discharge the soil and lime mixed in the mixing tank 1, and the connection status of the discharge pipe 20 can be controlled by the solenoid valve 21, which further improves the convenience of use.

[0031] The working principle of this utility model is as follows: When in use, first connect the electric telescopic rod 2, auxiliary water pump 9, servo motor 14 and solenoid valve 21 to the power supply, and open the cover plate 17. Add appropriate proportions of soil and lime into the mixing tank 1 through the feed pipe 16. Then start the servo motor 14, which drives the mixing shaft 4 to rotate, thereby causing the mixing blades 15 to rotate. The mixing blades 15 are used to mix the soil and lime in the mixing tank 1. When it is necessary to take out the mixed raw materials, open the solenoid valve 21, and then the raw materials in the mixing tank 1 can be discharged through the discharge pipe 20.

[0032] When cleaning is required inside the mixing tank 1, the servo motor 14, electric telescopic rod 2, and auxiliary water pump 9 are activated. The thrust generated by the electric telescopic rod 2 pushes the scraper 3 and spray pipe 6 downward. During the descent, the scraper 3 continuously rubs against the inner wall of the mixing tank 1, thereby cleaning the residual material adhering to the inner wall. At the same time, the mixing shaft 4 drives the pusher blade 5 to rotate. The rotation of the pusher blade 5 also rubs against the inner wall of the mixing tank 1, further increasing the thoroughness of the cleaning. In addition, the auxiliary water pump 9 can conduct water from the water storage tank 7 to the spray pipe 6 through the soft water pipe 10, and then spray it evenly onto the mixing tank 1 through the spray pipe 6, thereby cleaning the residual materials or additives. The cleaned impurities are discharged through the discharge pipe 20 and the solenoid valve 21, achieving the ability to automatically clean the inside of the mixing tank 1, avoiding residual impurities from affecting the accuracy of subsequent mixing, and effectively increasing the performance of the mixing device for soil remediation.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
