It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Please refer to the following: Figures 1 to 4 The present invention provides a description of the downhole slurry mixing device. The downhole slurry mixing device includes a mixing frame 1, a mixing tank 2, a mounting frame 3, a lifting frame 4, and a drive shaft 6. The mixing frame 1 has a placement space in its middle for placing the mixing tank 2; the mounting frame 3 is located at the opening of the mixing tank 2, and a stirring paddle 5 is rotatably mounted on the mounting frame 3; the lifting frame 4 is mounted on the mixing frame 1 and has a degree of freedom for vertical adjustment on the mixing frame 1, and the lifting frame 4 is detachably connected to the mounting frame 3; the drive shaft 6 is rotatably mounted on the mixing frame 1, and the drive shaft 6 is detachably connected to the main shaft of the stirring paddle 5.

[0026] The downhole slurry mixing device provided in this embodiment, compared with the prior art, features a mixing frame 1, which includes two columns fixed to the ground and a crossbeam fixed to the top of the two columns. A mixing tank 2 is placed between the two columns, and a mixing paddle 5 is rotatably mounted inside the mixing tank 2. A mounting frame 3 is provided at the opening of the mixing tank 2. The mounting frame 3 is detachably connected to a lifting frame 4, and the main shaft of the mixing paddle 5 is rotatably mounted on the mounting frame 3. A lifting frame 4 is also provided above the mounting frame 3, and the lifting frame 4 can move vertically on the mixing frame 1, and the lifting frame 4 is detachably connected to the mounting frame 3. A drive shaft 6 for connecting the main shaft of the mixing paddle 5 is rotatably mounted on the mixing frame 1. A pneumatic motor for driving the drive shaft 6 is also fixedly mounted on the mixing frame 1. During slurry mixing, by connecting the mounting frame 3 to the lifting frame 4 and then driving the lifting frame 4 upward, the main shaft of the mixing paddle 5 is connected to the drive shaft 6, thereby driving the mixing paddle 5 to rotate through the drive shaft 6, achieving the mixing of the raw materials. When it is necessary to clean the mixing tank 2 or the mixing paddle 5, the lifting frame 4 can be driven to move downwards, so that the mounting frame 3 can be attached to the top of the mixing tank 2 and the main shaft of the mixing paddle 5 can be disengaged from the drive shaft 6. Then the lifting frame 4 can be separated from the mounting frame 3, so that the mixing tank 2 and the mixing paddle 5 can be removed from the mixing frame 1, and the mixing paddle 5 can be removed from the inside of the mixing tank 2, which makes it convenient for the operator to clean the mixing tank 2 and the mixing paddle 5.

[0027] Specifically, in this embodiment, a mounting sleeve for mounting the stirring paddle 5 is provided on the mounting frame 3, and a rotating part with an outer diameter larger than the main shaft of the stirring paddle 5 is provided in the middle of the main shaft. The rotating part is rotatably disposed inside the mounting sleeve, and a limiting platform for limiting the movement of the rotating part along its axial direction is provided at both ends of the mounting sleeve.

[0028] In some embodiments, the drive shaft 6 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 An anti-rotation sleeve 61 for mounting the main shaft of the agitator 5 is fixedly installed at the end of the drive shaft 6. Fasteners 62 for fixing the main shaft of the agitator 5 into the anti-rotation sleeve 61 are threaded onto the side wall of the anti-rotation sleeve 61. An anti-rotation hole is provided inside the anti-rotation sleeve 61, which is fixedly installed at the end of the drive shaft 6. An anti-rotation rod is provided at the top of the main shaft of the agitator 5, which slides into the anti-rotation hole. The anti-rotation rod is inserted into the anti-rotation hole. Therefore, when the drive shaft 6 rotates, it can drive the agitator 5 to rotate together.

[0029] Specifically, in this embodiment, a fastener 62 is threaded onto the side wall of the anti-rotation hole. The fastener 62 is a bolt, and it is installed through the side wall of the anti-rotation hole and can be pressed against the outer side wall of the anti-rotation rod, thereby enhancing the stability of the connection between the drive shaft 6 and the stirring paddle 5.

[0030] In some embodiments, the lifting frame 4 described above can be as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 The lifting frame 4 is hinged with multiple tie rods 41, and the mounting frame 3 has openings for accommodating the tie rods 41. Each tie rod 41 is threaded with a limiting member 42 for abutting against the bottom of the mounting frame 3. Two tie rods 41 are hinged at each end of the lifting frame 4, and in the free state, the axis of the tie rods 41 is vertical. When the mounting frame 3 needs to be connected to the lifting frame 4, the position of the mounting frame 3 can be adjusted so that the multiple tie rods 41 are located inside the corresponding openings on the mounting frame 3. The limiting member 42 is then installed onto the tie rod 41, so that the limiting member 42 abuts against the top of the mounting frame 3. Therefore, when the lifting frame 4 moves upward, it can drive the mounting frame 3 to move upward as well.

[0031] Preferably, in this embodiment, crossbars are provided at both ends of the mounting frame 3, the opening slots are located on the crossbars, and two limiting members 42 are threadedly connected to a single pull rod 41. The two limiting members 42 are located on the upper and lower sides of the crossbar respectively, thereby improving the stability of the connection between the pull rod 41 and the mounting frame 3.

[0032] Specifically, in this embodiment, there are four tie rods 41, which are located at the four corners of the lifting frame 4. By adjusting the position of the upper limit member 42 of the four tie rods 41, the tilt angle of the mounting frame 3 can be adjusted, thereby adjusting the angle of the mixing paddle main shaft. This allows the end of the main shaft to be stably inserted into the drive shaft 6.

[0033] Meanwhile, when the pull rod 41 is inside the opening slot, the pull rod 41 can limit the mounting bracket 3 to rotate together with the stirring paddle 5, so that only the stirring paddle 5 rotates together with the drive shaft 6.

[0034] In some embodiments, the lifting frame 4 described above can be as follows: Figure 1 , Figure 4 The structure shown. See also... Figure 1 , Figure 4A guide post 43, arranged vertically, is fixedly installed on the lifting frame 4, and a guide sleeve 11, which slides with the guide post 43, is fixedly installed on the mixing frame 1. The guide post 43 is fixedly installed on the top of the lifting frame 4, and the guide sleeve 11, which slides with the guide post 43, is fixedly installed on the mixing frame 1. When the lifting frame 4 moves up and down, the guide sleeve 11 guides the lifting frame 4, ensuring that the lifting frame 4 can move stably in the vertical direction. Simultaneously, the stability of the lifting frame 4's position, when the mounting frame 3 is fixed to the lifting frame 4, improves the stability of the mixing paddle 5 during rotation.

[0035] In some embodiments, the stirring rack 1 described above may be as follows: Figure 1 , Figure 4 The structure shown. See also... Figure 1 , Figure 4 A screw lifter 7 is also installed on the mixing frame 1, and the drive end of the screw lifter 7 is fixedly installed on the lifting frame 4. The screw lifter 7 enables the lifting operation of the lifting frame 4 between the mixing frame 1 and the lifting frame 4. The screw lifter 7 includes a housing fixed on the mixing frame 1, and a threaded sleeve is rotatably installed inside the housing. A screw is threadedly connected inside the threaded sleeve, and one end of the screw is fixedly installed on the lifting frame 4. Thus, when the threaded sleeve rotates, it can drive the screw to move up and down, thereby driving the lifting frame 4 to move up and down.

[0036] In some embodiments, the screw jack 7 described above can be as follows: Figure 1 , Figure 4 The structure shown. See also... Figure 1 , Figure 4 There are two screw jacks 7, and the drive sources of the two screw jacks 7 are connected. The two screw jacks 7 work synchronously, and the two screw jacks 7 are spaced apart along the length of the lifting frame 4, which can ensure the stability of the lifting frame 4 during the up and down movement.

[0037] Specifically, in this embodiment, the screw jack 7 further includes a worm gear fixedly installed on the outside of the threaded sleeve. A worm gear, meshing with the worm gear, is rotatably mounted on the housing, and a polygonal hole is provided in the middle of the worm gear. The worm gears and polygonal holes on both screw jacks 7 are coaxially arranged. A drive shaft is inserted inside the corresponding worm gears on the two screw jacks 7. The drive shaft enables the two worm gears to rotate synchronously, thereby driving the screws to move synchronously. Furthermore, an explosion-proof motor or pneumatic motor for driving the drive shaft rotation is also installed on the stirring frame 1.

[0038] In some embodiments, the stirring tank 2 described above can be as follows: Figure 1 The structure shown. See also Figure 1A gravity block 8 is installed below the mixing rack 1, and the bottom of the mixing tank 2 is detachably installed on the gravity block 8. The gravity block 8 is fixedly placed on the ground, and multiple screws are fixedly installed on the gravity block 8. The multiple screws form a placement position for placing the mixing tank 2, and a limit plate is fixedly installed on the side wall of the mixing tank 2. The limit plate is provided with limit holes for avoiding the screws, and the limit plate can be fixed by bolting to the screws.

[0039] Specifically, in this embodiment, by fixing the mixing tank 2 to the gravity block 8, the weight of the mixing tank 2 itself can be increased, thereby reducing the shaking of the mixing tank 2 during the mixing process and improving the stability of the position of the mixing tank 2.

[0040] In some embodiments, the gravity block 8 can be adopted as follows: Figure 1 The structure shown. See also Figure 1 There are multiple gravity blocks 8, and adjacent gravity blocks 8 are spaced apart. In this embodiment, there are two gravity blocks 8, which are spaced apart. A insertion device can be used to move the mixing tank 2 between the two gravity blocks 8, insert it, and move it to another location for cleaning. This facilitates the removal of the gravity tank from under the mixing frame 1.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
