Abstract
Description
Technical Field
[0001] The utility model relates to a pipeline cleaning tool, in particular to a pipeline cleaning ball for conveying pipelines. Background Art
[0002] In the field of industrial production, with the popularization of automated production lines, various powder, liquid, and slurry pipeline transportation has been widely used. During the material transportation process, adhesion and deposition will form on the inner wall of the pipeline. In order to ensure smooth transportation and avoid contamination when switching between different materials, the inner wall of the pipeline needs to be cleaned. This has led to the demand for pipeline cleaning.
[0003] The current pipeline cleaning methods are divided into two types: manual cleaning and automatic cleaning. Manual cleaning means removing the pipeline and then manually cleaning it. When the pipeline is long, manual cleaning is time-consuming and labor-intensive, and can no longer adapt to the rhythm of automated transportation. Automatic cleaning uses cleaning balls to clean the inner wall of the pipeline. This method does not require the removal of the pipeline, and cleaning is convenient and quick. It has become the standard for long-distance pipeline transportation lines. The pipeline cleaning balls commonly used in this type of automatic transportation pipeline are mostly long cylindrical and have a large bending radius (the bending radius refers to the radius of the curved pipe that the cleaning ball can pass smoothly). In addition, in order to determine the position of the cleaning ball in the pipeline, the ball usually needs to be equipped with a magnet device for positioning. The magnet is mostly designed to be built into the ball and cast as one piece. The manufacturing cost is high, and the magnet cannot be replaced separately. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a pipe cleaning ball for a conveying pipeline, wherein the main components of the pipe cleaning ball are independent parts, which are connected in a detachable manner, are convenient to assemble and replace, are simple to manufacture, and have lower cost.
[0005] The technical solution to solve the above technical problems is: a pipe cleaning ball for a conveying pipeline, comprising a main sphere, a liquid pusher, a pipe cleaning lip and a magnet, wherein at least one end of the main sphere is provided with a mounting boss, the mounting boss is provided with an external thread, a groove is provided on the top surface of the mounting boss, an annular groove is provided between the mounting boss and the main sphere, the magnet is placed in the groove of the mounting boss, the pipe cleaning lip is in the shape of a circular ring, the inner ring of the pipe cleaning lip is clamped in the groove, the liquid pusher is connected to the mounting boss by a thread, and the liquid pusher clamps the pipe cleaning lip between the liquid pusher and the main sphere.
[0006] Furthermore, the liquid ejecting head is in the shape of a truncated cone with rounded chamfers, and a mounting groove with an internal thread connected to the mounting boss of the main sphere is provided inside the small end of the liquid ejecting head.
[0007] Furthermore, the cone angle β of the truncated cone of the liquid-pushing head is 45-55°, and the maximum outer diameter of the liquid-pushing head is 5-8 mm smaller than the inner wall diameter of the pipeline to be cleaned.
[0008] Furthermore, the main sphere is a cylindrical structure with a concave waist in the middle, and the diameter of the end of the main sphere is the same as the diameter of the small end of the top liquid head.
[0009] Furthermore, the outer diameter of the cleaning lip is 2 to 4 mm larger than the diameter of the inner wall of the pipeline to be cleaned.
[0010] Furthermore, the cleaning lip is made of silicone or fluororubber.
[0011] Furthermore, the main sphere, the mounting boss and the liquid top head are made of polytetrafluoroethylene.
[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0013] 1. The main components of the utility model, the main sphere, the top liquid head and the cleaning lip, are all independent parts, which are connected in a detachable manner, are easy to assemble and replace, are simple to make, can be replaced separately, and have lower cost.
[0014] 2. The middle part of the main sphere is designed to be concave waist-shaped. When the cleaning ball passes through the pipe bend, it can pass through a smaller bend radius, which is suitable for cleaning small radius bends in narrow spaces.
[0015] 3. The cross section of the top liquid head at the end of the cleaning ball is a large end face of an inverted trapezoid. During the pushing process, the area that bears the system's pushing air pressure is larger, the movement is more stable, the movement speed can be faster and more stable, and the uneven wear caused by the deviation of the ball due to uneven force is reduced. Because the inverted trapezoidal top liquid head pushes most of the material first, the cleaning lip is subjected to less force and has a longer life.
[0016] 4. The utility model can be provided with liquid pushers and cleaning lips at both ends of the main sphere, and can be used in bidirectional ball pushing / cleaning situations. The two cleaning lips are equivalent to two cleanings, and the effect is better.

[0023] Embodiment 1: A pipeline cleaning ball, such as Figure 1 As shown, it includes a main sphere 4, two top liquid heads 1, two cleaning lips 3 and two magnets 2. Both ends of the main sphere 4 are provided with mounting bosses 5. The mounting bosses 5 are provided with external threads. The top surface of the mounting bosses 5 is provided with a groove. A ring-shaped groove is provided between the mounting bosses 5 and the main sphere 4. The magnet 2 is an annular structure and is placed in the groove of the mounting boss 5. The magnet 2 has a magnetic property of more than 3500GS. The cleaning lip 3 is in the shape of a circular ring. The inner ring of the cleaning lip 3 is clamped in the groove. The top liquid head 1 is connected to the mounting boss 5 by threads. The top liquid head 1 clamps the cleaning lip 3 between the top liquid head 1 and the main sphere 4 to form a whole. The magnet 2 is fully covered in the top liquid head and the main sphere and will not contact the material. The magnet can be used in conjunction with the induction device to assist in detecting the position of the cleaning ball in the pipeline.
[0024] In this embodiment, the top liquid head 1 is in the shape of a truncated cone with rounded chamfers, and the cross-sectional shape of the top liquid head is an inverted trapezoid with rounded chamfers, and the large end of the inverted trapezoid is the material-facing surface. A mounting groove with an internal thread connected to the mounting boss 5 on the main sphere is provided inside the small end of the top liquid head 1. The mounting groove of the top liquid head 1 is connected to the external thread on the mounting boss 5 by threads. The truncated cone angle β of the top liquid head 1 is 45 to 55°, preferably 50°. The maximum outer diameter of the top liquid head 1 is 5 to 8 mm smaller than the inner wall diameter of the pipeline to be cleaned. As a modification, the truncated cone angle and the maximum outer diameter of the top liquid head can be adjusted as needed.
[0025] In this embodiment, the main sphere 4 is a cylindrical structure with a concave waist in the middle and rounded chamfers. The diameter of the end of the main sphere 4 is the same as the diameter of the small end of the top liquid head 1.
[0026] In this embodiment, the outer diameter of the cleaning lip 3 is 2-4 mm larger than the inner diameter of the pipeline to be cleaned. When the cleaning ball moves in the pipeline, the lip can clean / push out the residual materials in the pipeline.
[0027] In this embodiment, the cleaning lip is made of silicone or fluororubber. The main sphere, mounting boss and top liquid head are made of polytetrafluoroethylene, which is suitable for most materials and will not be corroded. As a change, the main sphere, mounting boss, top liquid head and cleaning lip can also be made of other suitable materials.
[0028] The cleaning ball of Example 1 is symmetrical at both ends and can be used for bidirectional ball pushing (i.e., after the cleaning ball moves from end A to end B of the pipeline, it does not need to turn around and then move from end B back to end A).
[0029] Working process of Example 1: The cleaning ball moves at high speed inside the pipeline, pushing the material in the pipeline from one end to the other end (exit). During the movement, the top liquid head pushes most of the material in the pipeline forward with its large end surface, and a small amount of material flows in opposite directions in the small gap between the top liquid head and the inner wall of the pipe, forming a buffer in the inverted trapezoidal top liquid head. The cleaning lip is in close contact with the inner wall of the pipe, scraping off the part of the material adhering to the inner wall of the pipe. After two cleaning lips, the cleaning effect is better.
[0030] Embodiment 2: A pipe cleaning ball for a conveying pipeline, such as Figure 2 As shown, it includes a main sphere 4, a top liquid head 1, a cleaning lip 3 and a magnet 2. One end of the main sphere 4 is provided with a mounting boss 5. The mounting method of the components is the same as that of Example 1.
[0031] Embodiment 2 is suitable for cleaning places where the cleaning ball only needs to move in one direction. The cleaning ball can only move in one direction to clean the pipe. When the reverse cleaning is required, the cleaning ball needs to be turned around before use. At this time, the overall length of the ball can be shortened, which is suitable for cleaning small curved pipes in smaller spaces.
