Description

Technical Field

[0001] This invention relates to the field of mud treatment, and more particularly to a pipeline mixing device for mud treatment. Background Technology

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

[0003] Conventional pipe mixers mainly utilize the fact that fluid passes through a spiral fixed inside a pipe, achieving fluid impact and cutting, and the spiral body rotates and mixes the fluid.

[0004] Patent CN202020847630.3 discloses an integrated screw conveyor for mud treatment, which uses a motor to drive the screw blades to rotate, thereby achieving the mixing and conveying of the mud mixture. However, for high-concentration mud, the rotating screw blades still exhibit uneven mixing. Furthermore, since one end of the screw blade is connected to the motor, transmission instability occurs, and the screw blades may damage the pipeline.

[0005] Mixing within a single spiral pipe significantly reduces the effectiveness of mud mixing and carries the risk of clogging the pipe, severely impacting the processing efficiency and effectiveness of downstream mud dewatering equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a pipe mixing device for mud treatment, wherein an eccentric spiral agitator is installed inside the clamped pipe to squeeze and mix the mud mixture entering the pipe, thereby improving the mud mixing effect.

[0007] To solve the above technical problems, the following technical solution is adopted: This invention provides a pipeline mixing device for mud treatment, including a clamped pipe and a spiral winch. The clamped pipe is a cylindrical structure with open ends. The spiral winch includes a transmission disc and an eccentric spiral agitator. The eccentric spiral agitator is disposed inside the clamped pipe. The transmission disc is disposed at one end of the clamped pipe. The transmission disc is connected to a driving component. The driving component is used to drive the transmission disc to rotate, thereby driving the eccentric spiral agitator to rotate. The clamping tube is provided with a positioning flange at one end, and the transmission disc is connected to the positioning flange.

[0008] Optionally, two clamping pipes are provided, and one end of each clamping pipe is connected to the positioning flange. The transmission disc is provided between the two positioning flanges. The eccentric spiral agitator is disposed in one of the clamping pipes, and the slurry enters from the other end of the other clamping pipe.

[0009] Optionally, a sliding sleeve for guiding the rotation of the transmission disc and a packing for lubrication are provided between the positioning flange and the transmission disc.

[0010] Optionally, the sliding sleeve is provided with a sliding groove, and both sides of the transmission disc are provided with convex rings that cooperate with the sliding groove.

[0011] Optionally, the sliding sleeve is mounted on the positioning flange, the positioning flange is provided with a flange groove for cooperating with the sliding sleeve, and the side of the flange groove is provided with a positioning protrusion for positioning and mounting the sliding sleeve.

[0012] Optionally, the transmission disc has annular grooves on both sides for mounting the packing.

[0013] Optionally, the positioning flange is provided with bolt holes, and the two positioning flanges are connected by a fastening bolt assembly.

[0014] Optionally, the eccentric spiral mixer includes a spiral blade and a shaft. The shaft has a multi-segment staggered structure, with at least two segments arranged off-center from the central axis of the spiral blade. The end of the shaft is connected to the transmission disk.

[0015] Optionally, the transmission disc is provided with a cross-shaped baffle at its center for breaking and cutting the mud.

[0016] Optionally, the driving component includes a motor, a drive pulley, and a transmission belt. The motor is connected to the drive pulley, and the drive pulley is connected to the transmission disc via the transmission belt.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. This invention sets an eccentric spiral agitator inside a clamping tube. The shaft of the eccentric spiral agitator is off-axis, and the gap between it and the inside of the clamping tube changes continuously. By repeatedly squeezing the mud, the medicine in the mud is completely mixed. The drive unit drives the transmission disk to rotate, thereby driving the eccentric spiral agitator to rotate, thus realizing the squeezing, stirring and transmission of the mud.

[0018] 2. The present invention provides a sliding sleeve and a packing between the transmission disc and the positioning flange, which guides and lubricates the rotation of the transmission disc, so that it remains stable and efficient during rotation.

[0019] 3. The present invention has a cross-shaped baffle at the center of the transmission disc. The baffle cuts and breaks the incoming mud, allowing it to enter the clamping pipe for better stirring. The rotating transmission disc performs preliminary mixing of the mud, and better stirring of mud with high concentration. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Example 1

[0023] like Figures 1-2 As shown, this embodiment provides a pipeline mixing device for mud treatment, including a clamped pipe and a spiral winch 2. The clamped pipe is a cylindrical structure with open ends. The spiral winch 2 includes a transmission disc 10 and an eccentric spiral agitator 11. The eccentric spiral agitator 11 is disposed inside the clamped pipe. The transmission disc 10 is disposed at one end of the clamped pipe. The transmission disc 10 is connected to a driving member. The driving member is used to drive the transmission disc 10 to rotate, thereby driving the eccentric spiral agitator 11 to rotate. The clamping tube is provided with a positioning flange 12 at one end, and the transmission disc 10 is connected to the positioning flange 12.

[0024] Specifically, the transmission disc 10 has a through hole in the center for the mud to pass through. The mud enters the clamp tube through the rotation of the transmission disc 10. Because the shaft of the eccentric spiral agitator 11 is off the central axis, the mud passing through is squeezed on one side of the clamp tube and transported on the other side when it rotates. The rotating eccentric spiral agitator 11 stirs, squeezes and transports the mud, and the mud and medicine are completely mixed. For some mud with high concentration, it can also be stirred evenly and will not be blocked in the clamp tube. Example 2

[0025] This embodiment provides a pipeline mixing device for mud treatment based on Embodiment 1, with the following differences: like Figure 2 As shown, the clamping pipe includes a first clamping pipe 1 and a second clamping pipe 5. One end of the first clamping pipe 1 and the second clamping pipe 5 is equipped with a positioning flange 12, and the other end is equipped with a conventional flange. The ends of the two clamping pipes with positioning flanges 12 are connected. A transmission disc 10 is disposed between the two positioning flanges 12. An eccentric spiral agitator 11 is disposed inside the first clamping pipe 1. The second clamping pipe 5 is used to enter the mud mixture. The other end of the second clamping pipe 5 is connected to the mud inlet. The other end of the first clamping pipe 1 is connected to the reaction tank. The mud mixture enters the second clamping pipe 5 from the mud inlet. The first clamping pipe 1 transports the mixed mud mixture to the reaction tank, where the mud mixture reacts fully.

[0026] like Figure 3 As shown, the eccentric spiral mixer 11 includes spiral blades and a shaft. The shaft has a multi-segmented, staggered structure, with at least two ends positioned off-center from the central axis of the spiral blades to achieve an eccentric arrangement. The ends of the shaft are connected to the center of the transmission disk 10. When the eccentric spiral mixer 11 rotates, the shaft, positioned off-center from the spiral blades, forms a larger gap with the wall of the first pair of clamping tubes 1, thus compressing the slurry transported to that position. As the slurry is transported to the next position, the gap between the spiral blades and the first pair of clamping tubes 1 increases, further transporting the compressed slurry. Through the rotation of the spiral blades, the slurries mix with each other, resulting in a more uniform slurry mixture after the eccentric spiral mixer 11 is installed.

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

[0028] like Figure 2 , such as 3, Figure 4As shown, the positioning flange 12 is provided with a flange groove 16 for installing the sliding sleeve 4. A positioning protrusion 17 is provided on the side of the flange groove 16 for positioning and installing the sliding sleeve 4, thereby positioning and installing the sliding sleeve 4 within the flange groove 16. Both sides of the transmission disc 10 are provided with annular grooves 18 for installing the packing 3, and a raised 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 disk 10 is installed in the sliding groove 14 through the convex ring 15. The transmission disk 10 is guided to rotate within the sliding sleeve 4. The packing 3 can be made of graphite material. The graphite packing 3 is located on both sides of the transmission disk 10 to achieve the lubrication effect when the transmission disk 10 rotates.

[0030] like Figure 2 , Figure 5 As shown, the positioning flange 12 is provided with bolt holes 13. 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 a fastening bolt assembly 6. The transmission disc 10 between the two flanges has a rotational clearance. The fastening bolt assembly 6 ensures the stable rotation of the transmission disc 10. The transmission disc 10 rotates with resistance between the two positioning flanges 12, ensuring the stability of the rotation.

[0031] like Figure 3 As shown, a cross-shaped baffle 19 is provided in the center of the transmission disc 10. The baffle breaks and cuts the mud, which facilitates subsequent uniform mixing.

[0032] like Figure 2 As shown, the driving component includes a motor 7, a drive wheel 9, and a transmission belt 8. The motor 7 is connected to the drive wheel 9, and the drive 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 rotation of the drive wheel 9 drives the transmission disc 10 to rotate. The rotating transmission disc 10 then drives the eccentric spiral agitator 11 set in the first pair of clamping tubes 1 to rotate, so as to uniformly mix the mud and transfer it to the next process.

[0033] In use, the mud and medicine are added into the second pair of clamp tubes 5. The mud is broken and cut by the cross-shaped baffle in the middle of the transmission disc 10 and is initially mixed. Then it enters the first pair of clamp tubes 1. During the rotation of the eccentric spiral agitator 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. The mud and medicine entering the first pair of clamp tubes 1 are repeatedly squeezed and stirred. The mud and medicine are completely mixed and then output from the other end of the first pair of clamp tubes 1.
