[0002] In the process of mud dewatering, mud conditioning is the most critical, which plays a key role in modifying the mud, improving the mud-water separation effect and mud dewatering efficiency.

[0003] Conventional pipeline mixers mainly use the fluid passing through a spiral fixed in the pipeline to achieve fluid impact cutting and achieve the effect of rotating mixing with the pipeline spiral.

[0004] The patent number "CN202020847630.3" discloses a dosing, stirring and conveying integrated machine for mud treatment. The motor drives the spiral blade to rotate, thereby achieving the stirring and conveying of the mud mixture. However, for mud with higher concentrations, the rotating spiral blade still causes uneven stirring. In addition, one end of the spiral blade is connected to the motor, which will cause unstable transmission and damage the pipeline.

[0005] If the mud is mixed in this single spiral pipe, the mixing effect of the mud will be greatly reduced, and there is also the risk of clogging the pipe, which seriously affects the treatment effect and efficiency of the rear-end mud filter pressing and dehydration equipment.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Example 1

[0023] like Figure 1-Figure 2 As shown, this embodiment provides a pipeline mixing device for mud treatment, including a clamped pipe and a spiral capstan 2, wherein the clamped pipe is a cylindrical structure with two ends opened, and the spiral capstan 2 includes a transmission disc 10 and an eccentric spiral stirring body 11, wherein the eccentric spiral stirring body 11 is arranged in the clamped pipe, and the transmission disc 10 is arranged at one end of the clamped pipe, wherein the transmission disc 10 is connected to a driving member, and the driving member is used to drive the transmission disc 10 to rotate, thereby driving the eccentric spiral stirring body 11 to rotate; A positioning flange 12 is provided at one end of the clamping tube, and the transmission plate 10 is connected to the positioning flange 12 .

[0024] Specifically, a through hole for passing mud is provided in the center of the transmission disk 10. The mud enters the clamping tube through the rotation of the transmission disk 10. Since the shaft of the eccentric spiral stirring body 11 deviates from the position of the central axis, the passing mud is squeezed on one side of the clamping tube and transmitted on the other side during rotation. The mud is stirred, squeezed and transmitted by the rotating eccentric spiral stirring body 11, and the mud and the medicine are completely mixed. For some muds with higher concentrations, they can also be stirred evenly without being blocked in the clamping tube. Example 2

[0025] This embodiment provides a pipeline mixing device for mud treatment based on the embodiment 1, except that: like Figure 2 As shown, the clamping tubes include a first pair of clamping tubes 1 and a second pair of clamping tubes 5. One end of the first pair of clamping tubes 1 and the second pair of clamping tubes 5 is provided with a positioning flange 12, and the other end is provided with a conventional flange. The ends of the two clamping tubes provided with the positioning flange 12 are connected, and the transmission plate 10 is arranged between the two positioning flanges 12. The eccentric spiral stirring body 11 is arranged in the first pair of clamping tubes 1. The second pair of clamping tubes 5 are used to enter the mud. The other end of the second pair of clamping tubes 5 is connected to the mud inlet, and the other end of the first pair of clamping tubes 1 is connected to the reaction box. The mud mixture enters the second pair of clamping tubes 5 from the mud inlet. The first pair of clamping tubes 1 transports the mixed mud mixture to the reaction box, and the mud mixture is fully reacted in the reaction box.

[0026] like Figure 3 As shown, the eccentric spiral stirring body 11 includes a spiral blade and a shaft, and the shaft is a multi-stage staggered structure, wherein at least two ends of the shaft are distributed at positions deviating from the central axis of the spiral blade to achieve an eccentric setting, and the end of the shaft is connected to the center of the transmission disk 10. When the eccentric spiral stirring body 11 rotates, at the position where the shaft deviates from the spiral blade, when rotating, a larger gap will be formed with the wall of the first pair of clamping tubes 1, thereby squeezing the mud transmitted to this position. When the mud is transmitted to the next position, the gap between the spiral blade and the first pair of clamping tubes 1 increases, and the squeezed mud is transmitted. The muds are mixed with each other through the rotation of the spiral blade. After the eccentric spiral stirring body 11, the mud is mixed more evenly.

[0027] like Figure 2 As shown, a sleeve 4 for guiding the rotation of the transmission disc 10 and a packing 3 for lubrication are provided between the positioning flange 12 and the transmission disc 10. Two sleeves 4 and two packings 3 are provided. The two sleeves 4 are respectively installed on the two positioning flanges 12, and the two packings 3 are respectively installed on the two sides of the transmission disc 10.

[0028] like Figure 2 , such as 3, Figure 4As shown, a flange slot 16 for mounting the sleeve 4 is provided on the positioning flange 12. A positioning protrusion 17 for positioning and mounting the sleeve 4 is provided on the side of the flange slot 16, and the sleeve 4 is positioned and mounted in the flange slot 16 through the positioning protrusion 17. An annular groove 18 for mounting the packing 3 is provided on both sides of the transmission plate 10, and a convex ring 15 is provided on the outer annular surface of the annular groove 18.

[0029] like Figure 3 , Figure 6 , Figure 7 As shown, the sliding sleeve 4 is provided with a sliding groove 14, and the transmission disc 10 is installed by installing the convex ring 15 in the sliding groove 14, and the transmission disc 10 is guided to rotate in the sliding sleeve 4. The packing 3 can be made of graphite material, and the packing 3 made of graphite material is located on both sides of the transmission disc 10 to achieve lubrication when the transmission disc 10 rotates.

[0030] like Figure 2 , Figure 5 As shown, bolt holes 13 are provided on the positioning flange 12, and the diameter of the annular surface where the bolt holes 13 are located is larger than the diameter of the transmission disc 10. The two positioning flanges 12 are connected by the fastening bolt assembly 6, and the transmission disc 10 between the two flanges has a rotation gap, and the stable rotation of the transmission disc 10 is ensured by the fastening bolt assembly 6. The transmission disc 10 rotates with resistance between the two positioning flanges 12 to ensure the stability of the rotation.

[0031] like Figure 3 As shown, a cross-shaped baffle 19 is provided at the center of the driving disc 10, through which the mud is interrupted and cut to facilitate subsequent uniform mixing.

[0032] like Figure 2 As shown, the driving member includes a motor 7, a driving wheel 9 and a transmission belt 8. The motor 7 is connected to the driving wheel 9, and the driving wheel 9 is connected to the transmission disc 10 through the transmission belt 8. The transmission belt 8 is sleeved on the transmission disc 10. The driving wheel 9 rotates, thereby driving the transmission disc 10 to rotate. The rotating transmission disc 10 then drives the eccentric spiral stirring body 11 arranged in the first pair of clamping tubes 1 to rotate, so as to evenly mix the mud and transmit it to the next program.

[0033] When in use, mud and medicine are added into the second pair of clamp tubes 5, the mud is interrupted and cut by the cross-shaped baffle in the middle of the transmission disk 10, and is preliminarily mixed, and then enters the first pair of clamp tubes 1. During the rotation of the eccentric spiral stirring body 11, the gap between the spiral blades at each position inside the first pair of clamp tubes 1 and the inner wall of the first pair of clamp tubes 1 is different, and the mud and medicine entering the first pair of clamp tubes 1 are repeatedly squeezed and stirred, and the mud and medicine are completely mixed, and then output from the other end of the first pair of clamp tubes 1.
