Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-3This embodiment provides a technical solution: a mixing device for modified clay buffer backfill material, including a mixing support 1, which provides support for the mixing components of the modified clay buffer backfill material raw materials. A mounting shell 2 is vertically slidably connected inside the vertical shell of the mixing support 1. A stirring rod 3 is rotatably connected to the left end of the mounting shell 2. A mixing cylinder 4 is placed on the upper surface of the platform of the mixing support 1, providing space for mixing the modified clay buffer backfill material raw materials. The modified clay buffer backfill material raw materials are mixed by rotating the stirring rod 3. The vertical position of the stirring rod 3 is adjusted by moving the mounting shell 2 up and down, causing the stirring rod 3 to move away from the interior of the mixing cylinder 4. The mixed raw materials can be fed by simply moving the mixing cylinder 4. The front surface of the mixing support 1 is equipped with a microcontroller 11. The input end of the microcontroller 11 is electrically connected to an external power source to control the start and stop of the entire device. The vertical shell of the mixing support 1 is equipped with a lead screw motor 12. The motor end of the lead screw motor 12 is fixedly connected to the bottom wall of the vertical shell of the mixing support 1. The lead screw end of the lead screw motor 12 is rotatably connected to the top wall of the vertical shell of the mixing support 1. The lead screw of the lead screw motor 12 is threadedly connected to the screw hole on the right end of the mounting shell 2. The input end of the lead screw motor 12 is electrically connected to the output end of the microcontroller 11 to provide power for the up and down movement of the mounting shell 2. It also includes a shaking mechanism 5.
[0020] The material shaking mechanism 5 includes an inner hexagonal tube 51, an outer hexagonal column 52, and a spring 53. The inner hexagonal tube 51 is rotatably connected to the rotating groove at the left end of the mounting shell 2. The outer hexagonal column 52 is vertically slidably connected inside the inner hexagonal tube 51. The lower end of the outer hexagonal column 52 is fixedly connected to the rod body of the stirring rod 3. A spring 53 is provided between the limiting plate at the upper end of the outer hexagonal column 52 and the inner hexagonal tube 51. The spring 53 is movably sleeved on the outer arc surface of the outer hexagonal column 52. During the rotation of the inner hexagonal tube 51, because the inner hexagonal tube 51 and the outer hexagonal column 52 slide vertically, the relative rotation of the outer hexagonal column 52 and the inner hexagonal tube 51 is restricted. Therefore, the outer hexagonal column 52 also rotates, driving the stirring rod 3 to rotate, and mixing the modified clay buffer backfill material raw materials in the mixing drum 4. The shaking mechanism 5 also includes a top column 54, an external gear 55, and a top plate 56. The top column 54 is located on the upper surface of the external hexagonal column 52. The external gear 55 is rotatably connected to the top wall of the mounting housing 2 via a rotating shaft. The lower surface of the external gear 55 is eccentrically provided with top plates 56. The annularly distributed top plates 56 are fitted with the semi-circular ends of the top column 54. All top plates 56 are arc-shaped plates, and the lower surface of all top plates 56 is inclined. The shaking mechanism 5 also includes a gear 57 and a motor 58. The motor 58 is located inside the upper part of the mounting housing 2. The upper end of the output shaft of the motor 58 is provided with a gear 57, which meshes with the external gear 55. The input end of the motor 58 is electrically connected to the output end of the microcontroller 11. When the motor 58 is started, the output shaft of the motor 58 drives the gear 57 to rotate. The meshing connection between gear 57 and external gear 55 causes external gear 55 to drive top plate 56 to rotate. When the inclined surface of top plate 56 contacts the semi-circular end of top column 54, as top plate 56 continues to rotate, the inclined surface of top plate 56 gradually pushes top column 54 downward. Spring 53 contracts to generate elastic force. When the semi-circular end of top column 54 disengages from the inclined surface of top plate 56, the upward movement of top column 54 is unrestricted. Under the elastic force of spring 53, external hexagonal column 52 quickly moves upward and resets. As top plate 56 rotates, the above operation is repeated, driving stirring rod 3 to perform vertical reciprocating vibration. The outer arc surface of internal hexagonal tube 51 is provided with worm gear 6. The middle of the interior of mounting shell 2 is provided with drive motor 8. The left end of the output shaft of drive motor 8 is provided with worm 7. The rod of worm 7 The left end of the body is rotatably connected to the inner wall of the left side of the mounting shell 2. The worm 7 is meshed with the worm wheel 6. The input end of the drive motor 8 is electrically connected to the output end of the microcontroller 11. When the drive motor 8 is started, the output shaft of the drive motor 8 drives the worm 7 to rotate. Through the meshing connection between the worm 7 and the worm wheel 6, the worm wheel 6 drives the internal hexagon tube 51 to rotate. The lower surface of the mounting shell 2 is provided with a rubber ring 9. The rubber ring 9 is movably sleeved on the outer arc surface of the stirring rod 3. The upper end of the outer arc surface of the stirring rod 3 is provided with a circular ring 10. The circular ring 10 and the rubber ring 9 are installed together. During the up and down shaking of the stirring rod 3, the contact between the circular ring 10 and the rubber ring 9 compresses the rubber ring 9 and causes it to deform. The deformation of the rubber ring 9 reduces the transmission of force to the mounting shell 2 and reduces the generation of noise.
[0021] The working principle of the mixing device for modified clay buffer backfill material provided by this utility model is as follows: When producing modified clay buffer backfill material for sealing and solidifying radioactive nuclide adsorption materials, the raw material of the modified clay buffer backfill material is poured into the mixing cylinder 4. The microcontroller 11 starts the drive motor 8, and the output shaft of the drive motor 8 drives the worm gear 7 to rotate. Through the meshing connection between the worm gear 7 and the worm wheel 6, the worm wheel 6 drives the inner hexagonal tube 51 to rotate. Because the inner hexagonal tube 51 and the outer hexagonal column 52 slide vertically, restricting the relative rotation between the outer hexagonal column 52 and the inner hexagonal tube 51, the outer hexagonal column 52 also rotates, driving the stirring rod 3 to rotate, thus mixing the raw material of the modified clay buffer backfill material in the mixing cylinder 4. After mixing is completed, the lead screw motor 12 is started. The lead screw of the lead screw motor 12 rotates, and through the threaded connection between the lead screw and the screw hole of the mounting shell 2, it drives the mounting shell 2 to rotate on the vertical shell of the mixing support 1. The mixing rod 3 moves upward, disengaging from the mixing drum 4 and providing space for its movement. Then, the motor 58 is started, and its output shaft drives the gear 57 to rotate. Through the meshing connection between the gear 57 and the external gear 55, the external gear 55 drives the top plate 56 to rotate. When the inclined surface of the top plate 56 contacts the semi-circular end of the top column 54, the top plate 56 continues to rotate, gradually pushing the top column 54 downward. The spring 53 contracts, generating elastic force. When the semi-circular end of the top column 54 disengages from the inclined surface of the top plate 56, the upward movement of the top column 54 is unrestricted. Under the elastic force of the spring 53, the external hexagonal column 52 quickly moves upward and resets. As the top plate 56 rotates, the above operation is repeated, causing the mixing rod 3 to reciprocate vertically. This causes the material on the surface of the mixing rod 3 to detach and fall accurately into the mixing drum 4, reducing the adhesion of raw materials to the surface of the mixing rod 3 after mixing and facilitating subsequent cleaning.
[0022] It is worth noting that the microcontroller 11 disclosed in the above embodiments can be an AT89C4051 microcontroller. The motor 58, drive motor 8 and lead screw motor 12 can be freely configured according to the actual application scenario. The motor 58 can be a D08LD40-48A-30S motor, the drive motor 8 can be a 5IK40RGU-CF motor, and the lead screw motor 12 can be a 28E245-6.35-115 lead screw motor. The microcontroller 11 controls the operation of the motor 58, drive motor 8 and lead screw motor 12 using methods commonly used in the prior art.
