Description

Technical Field

[0001] The utility model relates to the technical field of pipe cleaning systems, in particular to a variable diameter ball receiving pipe structure. Background Art

[0002] In the fields of chemical industry, lithium battery, etc., after the slurry is transported in the pipeline for a period of time, some of the slurry will remain in the pipeline, resulting in reduced transportation efficiency and waste. To solve this problem, a pipe cleaning system is often used to clean the residual slurry in the pipeline. Compressed air is used to push away the residual slurry in the pipeline with a pipe cleaning ball. Elastic diaphragms are set at both ends of the pipe cleaning ball. When it is squeezed in the pipeline, it deforms and flanging. The flanging direction is opposite to the movement direction of the pipe cleaning ball. After moving from the serving position to the receiving position, the pipe cleaning ball needs to be sent back to its original position to achieve two-way pipe cleaning. Due to the opposite movement direction, when the pipe cleaning ball moves in the opposite direction, the elastic diaphragm needs to change direction, but the elastic diaphragm is in close contact with the inner wall of the pipeline. If you want to make the two diaphragms change direction and flanging at the same time, you need to provide a huge thrust, that is, you need to configure a cylinder, use the push block deep in the pipeline to push the pipe cleaning ball to move in the opposite direction and let the diaphragm reversely flanging, resulting in a large space occupied by the receiving side, and there will be a problem of jamming during the reverse push process. Summary of the invention

[0003] In order to solve the problems that the existing cleaning balls are difficult to turn and the ball receiving area occupies a large space, the utility model provides a variable diameter ball receiving pipe structure, which has a small volume and can easily realize the turning of the cleaning balls, thereby improving the reverse cleaning efficiency.

[0004] The technical solution is as follows: a variable diameter ball collecting tube structure, which includes a ball collecting pipeline, characterized in that the end of the ball collecting pipeline is connected to one end of a variable diameter tube, the inner diameter of the middle section of the variable diameter tube is larger than the inner diameter of the two ends, the other end of the variable diameter tube is connected to a tail pipe, a block is provided in the tail pipe and an air inlet and a sewage outlet are opened on the side wall.

[0005] Its further feature is that a magnetic induction switch is arranged outside the reducer.

[0006] After the utility model is adopted, when the pipe cleaning ball reaches the ball receiving position and passes through the reducer, one of the elastic diaphragms is no longer squeezed and deformed by the pipeline and can be reset and expanded. When pushing in the reverse direction, it is only necessary to overcome the resistance caused by the single elastic diaphragm, and the compressed air introduced into the air inlet can be used to push the pipe cleaning ball in the reverse direction without the problem of getting stuck. The cylinder and other components at the tail are omitted, the structure is simplified, the volume is reduced, the turning of the pipe cleaning ball can be easily realized, and the efficiency of reverse pipe cleaning is improved.

[0011] See Figure 1 As shown, a variable diameter ball receiving pipe structure includes a ball receiving pipe 1, the end of the ball receiving pipe 1 is connected to one end of a variable diameter pipe 2, the inner diameter of the middle section of the variable diameter pipe 2 is larger than the inner diameter of the two ends, to ensure that the elastic diaphragm on the cleaning ball 3 can be unfolded in the middle section without being squeezed by the pipe wall, and the other end of the variable diameter pipe 2 is connected to the tail pipe 4, a block 5 is provided in the tail pipe 4, and an air inlet 6 and a sewage outlet 7 are provided on the side wall, the sewage outlet 7 discharges the residual slurry brought by the cleaning ball 3, and the air inlet 6 provides the power for the cleaning ball 3 to move in the opposite direction. A magnetic induction switch 8 is provided on the outside of the variable diameter pipe 2 to detect the position of the cleaning ball 3.

[0012] The working principle is as follows: When the cleaning ball 3 moves forward and enters the reducer 2, Figure 2 As shown, the cleaning ball 3 partially enters the reducer 2. At this time, the elastic diaphragm 4-1 is located in the middle section of the reducer 2 and is no longer squeezed and expanded. The elastic diaphragm 4-2 is located at the end of the ball receiving pipeline 1 or the reducer 2 and is still squeezed and deformed, and is turned toward the ball receiving pipeline 1. As the cleaning ball 3 continues to move forward and contacts the stopper 5, as shown in FIG. Figure 3 As shown, the elastic diaphragm 4-2 is located in the middle section of the reducer 2 and is no longer squeezed and thus expanded, while the elastic diaphragm 4-1 is located at the end of the reducer 2 and is squeezed and deformed, and is turned toward the tail pipe 4 and the ball receiving pipe 1, and the residual slurry brought by the cleaning ball 3 is discharged from the opened sewage outlet 7; the cleaning ball 3 is ready to move in the reverse direction, the sewage outlet 7 is closed, the air inlet 6 is opened, and compressed air is introduced to push the cleaning ball 3 to move in the reverse direction, and the elastic diaphragm 4-1 may maintain the status quo and enter the middle section of the reducer 2 to expand, or it may directly turn around and turn around, that is, turn over in the direction of the tail pipe 4, as shown in FIG. Figure 4 As shown, after entering the middle section of the reducer 2, the elastic diaphragm 4-2 enters the ball receiving pipe 1, and is squeezed and turned toward the tail pipe 4 until the entire cleaning ball 3 enters the ball receiving pipe 1 to complete the turn and move in the opposite direction. During the entire turn, only the resistance of a single elastic diaphragm and the pipe wall needs to be overcome, which reduces the difficulty of turning and improves efficiency.
