It is a basic industry that supports the operation of modern society and has both scientific and practical aspects.

[0003] The existing delivery pipes require workers to fix them with bolts, which is complicated and cannot be spliced ​​without tools. In addition, if the liquid contains impurities, it may cause blockages in subsequent devices. Utility Model Content

[0004] The purpose of this utility model is to provide a chemical conveying pipe to solve the problems mentioned in the background art.

[0005] This utility model provides a chemical conveying pipe, comprising two pipes, and further comprising:

[0006] Two fixing rings are respectively fixedly installed at one end of two pipes. Two first fixing posts are fixedly installed on one of the fixing rings. One end of each of the two first fixing posts passes through the other fixing ring. The two first fixing posts are inserted into the other fixing ring to connect the two fixing rings together.

[0007] Two sliding grooves are respectively opened in two first fixed columns. Two sliding blocks are slidably installed in each of the two sliding grooves. The two sliding blocks slide and move away from each other. Both sliding blocks are in contact with another fixed ring, which can fix the position of the two fixed rings. A fixed frame is inserted into one of the pipes. A filter screen is fixedly installed in the fixed frame. The filter screen can intercept impurities in the liquid and ensure that impurities do not enter the subsequent device.

[0008] Two sets of drive components, each set of drive components is located within one of the fixed rings and is used to drive the four sliding blocks to slide;

[0009] A fixing component, located inside one of the pipes, is used to fix the position of the fixing frame.

[0010] By adopting the above technical solution, the driving component can drive the two sliding blocks to slide and move closer to each other. When both sliding blocks are fully inserted into the sliding groove, the two fixed rings can be connected together. At the same time, the two first fixed posts are inserted into the other fixed ring. Through the above reverse operation, the two sliding blocks slide and move away from each other. Both sliding blocks are in contact with the other fixed ring, which can fix the position of the two fixed rings. This makes it convenient for workers to install the two fixed rings. The operation is simple and does not require the use of tools.

[0011] When the filter needs to be replaced, the fixing frame and filter can be removed using the fixed components. Then, a new fixing frame can be inserted into the fixing ring. The fixing components can fix the position of the fixing frame. The filter can intercept impurities in the liquid, ensuring that impurities do not enter the subsequent device and making it easy to replace the filter.

[0012] Preferably, the driving component includes:

[0013] A sliding bar is slidably installed in a sliding groove. Two connecting rods are rotatably installed at one end of the sliding bar, and the two connecting rods are rotatably connected to two sliding blocks respectively. A second fixing post is fixedly installed at the other end of the sliding bar. One end of the second fixing post passes through one of the fixing rings and extends to the outside. A first spring is sleeved on the second fixing post.

[0014] By adopting the above technical solution, firstly, the two second fixed columns are pulled to slide, while the first spring is compressed and contracted. The second fixed columns drive the sliding strip to slide, and the sliding strip pulls the two connecting rods to rotate. The two connecting rods respectively pull the two sliding blocks to slide and move closer to each other. When both sliding blocks are fully inserted into the sliding groove, the two fixed rings can be connected together. At the same time, both first fixed columns are inserted into the other fixed ring. Then, the handle is released. Through the above reverse operation, the two sliding blocks slide and move away from each other. Both sliding blocks are in contact with the other fixed ring, which can fix the position of the two fixed rings.

[0036] The following is in conjunction with the appendix Figure 1 and Figure 6 This application will be described in further detail.

[0037] This application discloses a chemical conveying pipe.

[0038] Reference Figure 1 and Figure 5 A chemical conveying pipe, comprising two pipes 1, and further comprising:

[0039] Two fixing rings 2 are fixedly installed at one end of two pipes 1 respectively. Two first fixing posts 3 are fixedly installed on one of the fixing rings 2. One end of each of the two first fixing posts 3 passes through the other fixing ring 2. Both first fixing posts 3 are inserted into the other fixing ring 2 to connect the two fixing rings 2 together.

[0040] Two sliding grooves 4 are respectively opened in two first fixed columns 3. Two sliding blocks 5 are slidably installed in each of the two sliding grooves 4. The two sliding blocks 5 slide and move away from each other. Both sliding blocks 5 are in contact with another fixed ring 2, which can fix the position of the two fixed rings 2. A fixed frame 6 is inserted into one of the pipes 1. A filter screen 7 is fixedly installed in the fixed frame 6. The filter screen 7 can intercept impurities in the liquid and ensure that impurities do not enter the subsequent device.

[0041] Two sets of drive components, each located within one of the fixed rings 2, are used to drive the four sliding blocks 5 to slide.

[0042] A fixing component is located inside one of the pipes 1 and is used to fix the position of the fixing frame 6.

[0043] The drive component allows two sliding blocks 5 to slide and move closer to each other. When both sliding blocks 5 are fully inside the sliding groove 4, the two fixing rings 2 can be joined together. At the same time, the two first fixing posts 3 are inserted into the other fixing ring 2. Through the above reverse operation, the two sliding blocks 5 slide and move away from each other. Both sliding blocks 5 are in contact with the other fixing ring 2, which can fix the position of the two fixing rings 2. This makes it convenient for workers to install the two fixing rings 2, and the operation is simple and does not require tools.

[0044] When the filter screen 7 needs to be replaced, the fixing frame 6 and the filter screen 7 can be removed by using the fixing components. Then, the new fixing frame 6 can be inserted into the fixing ring 2. The fixing components can fix the position of the fixing frame 6. The filter screen 7 can intercept impurities in the liquid, ensuring that impurities do not enter the subsequent device and making it convenient to replace the filter screen 7.

[0045] refer to Figure 4 The driving components include:

[0046] The sliding bar 8 is slidably installed in the sliding groove 4. Two connecting rods 9 are rotatably installed at one end of the sliding bar 8. The two connecting rods 9 are rotatably connected to two sliding blocks 5 respectively. A second fixing post 10 is fixedly installed at the other end of the sliding bar 8. One end of the second fixing post 10 passes through one of the fixing rings 2 and extends to the outside. A first spring 11 is sleeved on the second fixing post 10.

[0047] First, the two second fixed posts 10 are pulled to slide, while the first spring 11 is compressed and contracted. The second fixed posts 10 drive the sliding strip 8 to slide, and the sliding strip 8 pulls the two connecting rods 9 to rotate. The two connecting rods 9 respectively pull the two sliding blocks 5 to slide and move closer to each other. When the two sliding blocks 5 are fully inserted into the sliding groove 4, the two fixed rings 2 can be connected together. At the same time, the two first fixed posts 3 are inserted into the other fixed ring 2. Then, the handle 12 is released. Through the above reverse operation, the two sliding blocks 5 slide and move away from each other. The two sliding blocks 5 are in contact with the other fixed ring 2, which can fix the position of the two fixed rings 2. This makes it convenient for the staff to install the two fixed rings 2, and the operation is simple and does not require the use of tools.

[0048] refer to Figure 6 The fixed components include:

[0049] The limiting groove 13 is formed inside one of the fixed rings 2. Two guide rods 14 are fixedly installed inside the limiting groove 13. The same pull rod 15 is slidably installed on the two guide rods 14. A second spring 16 is sleeved on both guide rods 14.

[0050] When the filter screen 7 needs to be replaced, first pull the lever 15 to slide it outward. At the same time, both second springs 16 are compressed and contracted. After one end of the lever 15 is separated from the fixed frame 6, the fixed frame 6 and the filter screen 7 can be removed.

The handles 12 drive the second fixed column 10 to slide. At the same time, the first spring 11 is compressed and contracted. The second fixed column 10 drives the sliding strip 8 to slide. The sliding strip 8 pulls the two connecting rods 9 to rotate. The two connecting rods 9 respectively pull the two sliding blocks 5 to slide and move closer to each other. When the two sliding blocks 5 are completely inserted into the sliding groove 4, the two fixed rings 2 can be connected together. At the same time, the two first fixed columns 3 are inserted into the other fixed ring 2. Then, release the handles 12. Through the above reverse operation, the two sliding blocks 5 slide and move away from each other. The two sliding blocks 5 are in contact with the other fixed ring 2, which can fix the position of the two fixed rings 2. It is convenient for the staff to install the two fixed rings 2. The operation is simple and does not require the use of tools.

[0060] When the filter screen 7 needs to be replaced, first pull the lever 15 to slide it outward. At the same time, both second springs 16 are compressed and contracted. After one end of the lever 15 is separated from the fixed frame 6, the fixed frame 6 and the filter screen 7 can be removed.
