Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing and production, in particular to a slurry conveying pipeline dredging device. Background Art

[0002] Currently, in the lithium-ion battery industry, after the electrode process is stirred and homogenized, a slurry conveying system is generally used to transport the slurry through a pipeline to the coating process. During the coating process, it is inevitable to encounter changes in model and abnormally long shutdowns. Long shutdowns will cause the slurry in the conveying pipeline to settle and aggregate at the bottom of the pipeline, especially at the bottom of right-angle pipelines and U-shaped pipelines.

[0003] In order to solve the above-mentioned situation where it is difficult to clean the slurry, a slurry conveying pipeline dredging device is proposed. For example, the prior art Chinese patent publication number "CN112443722A" discloses a conveying pipeline dredging device, which includes a driving component and a driven component; the driven component is placed in the pipeline to be dredged, and the driving component is slidably installed on the pipeline to be dredged along the axial direction of the pipeline to be dredged, and the driving component and the driven component are magnetically adsorbed and connected. When the conveying pipeline dredging device disclosed in the present invention is used, the driving component is placed on the outer wall of the pipeline to be dredged, the driven component is placed in the pipeline to be dredged, and the driving component and the driven component are magnetically adsorbed and connected; then, the driving component is dragged to slide quickly toward the position of the stuck ball in the pipeline to be dredged, and the driving component drives the driven component to move quickly to hit the ball, and the impulse of the driven component destroys the stuck bridge, thereby achieving dredging of the pipeline to be dredged.

[0004] In actual operation, for the fine gaps in right-angle pipes and pipe joints, the card ball cleaning method has dead corners that cannot be cleaned and the cleaning effect is poor. In addition, for dry materials deposited in the pipes, the card ball cleaning method is not thorough enough. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the ball cleaning method is not effective for the fine gaps in right-angle pipes and pipe connections, and to propose a slurry conveying pipe dredging device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A slurry conveying pipeline dredging device is designed, including a dredging device arranged in the pipeline, the pipeline forming a connecting portion and a straight-through portion through a connecting pipe, the dredging device including an ultrasonic vibrating rod, the ultrasonic vibrating rod being fixed to the outer wall of the pipeline through a connecting piece, and the output end of the ultrasonic vibrating rod being arranged inside the connecting portion;

[0008] Wherein, the input end of the ultrasonic vibration rod is connected to a connecting wire, and the input end is also provided with a winding component for winding the connecting wire.

[0009] Furthermore, the winding assembly includes an annular groove and a shell. The annular groove is provided on the periphery of the input end of the ultrasonic vibration rod. One side of the shell is recessed to form a cavity, and a clamping portion is extended toward the axis at the opening of the cavity to form a clamping portion. The clamping portion is rotatably connected to the annular groove.

[0010] Furthermore, the housing is a columnar structure, and a threading hole is provided on its side and a winding roller is fixed at the center point of the cavity, and an electric slip ring is provided at the free end of the winding roller;

[0011] The connecting wire is wound around the periphery of the winding roller, and the movable end thereof is passed through the wire hole, and the electric slip ring is respectively connected to the fixed end of the connecting wire and the ultrasonic vibration rod.

[0012] Furthermore, the shell is divided into two halves along the central axis, and the dividing line avoids the winding roller and the threading hole. The periphery of the shell on both sides is provided with ridges along the axis, and the ridges on both sides of the dividing line can be attached and fixed by fixing parts.

[0013] Furthermore, the fixing member includes a positioning hole and a positioning column, and the positioning hole and the positioning column are respectively provided between one side of the convex ridges on two adjacent sides, and the positioning hole is plugged into the positioning column.

[0014] Furthermore, it also includes bolts and nuts, wherein the bolts are passed through the other sides of the ridges on two adjacent sides, and the bolts are threadedly connected to the nuts.

[0015] The utility model proposes a slurry conveying pipeline clearing device, which has the following beneficial effects: the utility model adds an ultrasonic cleaning vibrator at equal distances (effective cleaning distance) in the pipeline, and utilizes high-frequency vibration and cavitation phenomena to effectively clean the fine gaps in right-angle pipelines and joints, solving the problem that the traditional ball-pushing method has poor cleaning effect at this position. In addition, the dry material deposited in the pipeline can be better cleaned by using the ultrasonic vibrator, and considering that the connecting line of the ultrasonic vibrator is too long and may cause wire mixing and winding, the connecting line can be wound by the winding component, which has strong practicality.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings 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.

[0022] Reference Figure 1-4 A slurry conveying pipeline dredging device includes a dredging device 2 arranged in a pipeline 1, wherein the pipeline 1 is connected to form a connecting portion 11 and a straight portion 12 through a connecting pipe. The dredging device 2 includes an ultrasonic vibrating rod 21, which is fixed to the outer wall of the pipeline 1 through a connecting piece, and its output end is arranged inside the connecting portion 11;

[0023] The input end of the ultrasonic vibration rod 21 is connected to a connecting wire 211 , and a winding component 3 for winding the connecting wire 211 is also provided at the input end.

[0024] It should be added that the connecting pipes include right-angle pipe joints and U-shaped pipe joints. Considering that the traditional ball-pushing method has a poor cleaning effect at this location, the ultrasonic vibrating rod 21 is used at this location to remove dirt. The connecting piece is a connecting flange, and the ultrasonic vibrating rod 21 and the connecting pipe are fixed by the connecting flange, and a sealing gasket is provided between the connecting flanges.

[0025] In addition, the dredging device 2 further includes a vibration motor, which is fixed in pairs on the outer wall of the straight-through portion 12 to assist the ultrasonic vibration rod 21 in accelerating the removal of dirt;

[0026] In addition, the ultrasonic vibration rod 21 is connected to an external ultrasonic generator and a transducer wire through the connecting line 211 .

[0027] Furthermore, the winding assembly 3 includes an annular groove 31 and a shell 32. The annular groove 31 is provided on the periphery of the input end of the ultrasonic vibration rod 21. One side of the shell 32 is recessed to form a cavity, and a clamping portion 33 is extended toward the axis at the opening of the cavity. The clamping portion 33 is rotatably connected to the annular groove 31.

[0028] Furthermore, the housing 32 is a columnar structure, and a threading hole 321 is provided on its side. A winding roller 34 is fixed at the center of the cavity, and an electric slip ring 35 is provided at the free end of the winding roller 34.

[0029] The connecting wire 211 is wound around the outer periphery of the winding roller 34 , and the movable end thereof passes through the threading hole 321 . The electric slip ring 35 is respectively connected to the fixed end of the connecting wire 211 and the ultrasonic vibration rod 21 .

[0030] It is worth mentioning that the electric slip ring 35 is a prior art device that can transmit current between a rotating body and a fixed body. The rotating body and the fixed body can be used to reel in the movable end of the connecting wire 211 and prevent the fixed end from being twisted during reeling.

[0031] In specific operation, the bolt 373 is rotated to create a certain gap between the pair of housings 32, but not to the extent that the pair of housings 32 are separated. After the housings 32 on both sides are loosened, the housings 32 are rotated using the clamping portion 33. The housings 32 drive the winding roller 34 to rotate and reel in the connecting wire 211, while the electric slip ring 35 is used to prevent the fixed end from being pulled.

[0032] After the bolts 373 are fixed, the pair of housings 32 are closed and the clamping portion 33 is used to bite the annular groove 31 to prevent the housing 32 from rotating freely. Of course, an anti-slip pad is provided on the periphery of the clamping portion 33 or the annular groove 31.

[0033] In more detail, the shell 32 is divided into two halves along the central axis, and the dividing line avoids the winding roller 34 and the threading hole 321. The outer periphery of the shell 32 on both sides is provided with ridges 36 along the axis, and the ridges 36 on both sides of the dividing line can be attached and fixed by fixing parts 37.

[0034] In general, the fixing member 37 includes a positioning hole 371 and a positioning column 372 . The positioning hole 371 and the positioning column 372 are respectively provided between one side of the ribs 36 on two adjacent sides, and the positioning hole 371 is plugged into the positioning column 372 .

[0035] Finally, it further includes bolts 373 and nuts. The bolts 373 are passed through the other sides of the ridges 36 on two adjacent sides, and the bolts 373 are threadedly connected to the nuts.

[0036] Working mode: When working, the ultrasonic vibrating rod 21 is fixed by the connecting flange. After the fixing is completed, the connecting line 211 needs to be properly reeled:

[0037] The bolts 373 are rotated to create a certain gap between the pair of housings 32. After the housings 32 on both sides are loosened, the housings 32 are rotated using the clamping portion 33. The housings 32 drive the winding roller 34 to rotate and reel in the connecting wire 211. Then, the bolts 373 are fixed, the pair of housings 32 are closed, and the clamping portion 33 is used to bite the annular groove 31 to prevent the housings 32 from rotating freely.

[0038] Finally, high-frequency vibration and cavitation are used for cleaning. The microbubbles in the pipe liquid vibrate at high frequencies. The formation, growth and implosion of the microbubbles will instantly generate shock waves, causing a pressure of 1012-1013 Pa and local temperature rise around the bubbles. This phenomenon can cause fatigue damage to the dirt and cause it to peel off. Once the dirt has a gap to drill through, the bubble vibration will continue to act to make the dirt fall off. In addition, combined with the ball pushing and vibration of the vibration motor, it can provide cleaning efficiency and effect.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
