Description

Technical Field

[0001] The utility model relates to the technical field of pipe cleaning devices, in particular to an automatic launching station with an EPDM buffer device. Background Art

[0002] Pigging technology has been around in various forms since the early 20th century. Today, a wide variety of sectors, industries, and applications handling liquids and powders use pigging to recover liquids and powders from pipelines, reducing waste and improving the efficiency of manufacturing and production processes. The primary purpose of pigging is to remove or recover residual product that remains in a pipeline after being transported from one point to another in a production line. In its simplest form, a pigging system consists of an elastic projectile with a diameter slightly larger than the piggable line, or even the product being processed, propelled through the pipeline to remove or recover high-value product.

[0003] As a major component of the pigging system, the launch station is responsible for launching the balls in the pigging system and is the starting point for the pig to recover the products. In the automatic pigging system, the pig starts from the automatic launch station and pushes the products in the pipeline to the end point of the pigging, that is, the recycling station. After the pig pushes the product to the recycling station in the automatic pigging system, a pushing medium is introduced at the end of the recycling station to push the pig in the recycling station back to the launch station to prepare for the next pigging cycle, without the need for manual ball retrieval. However, the pig is pushed by the pushing medium in the recycling station. When the pig reaches the launch station at a certain speed and hits the launch station, the push rod stops. When the pig hits the launch station push rod at a certain speed, the impact force generated may cause irreversible damage to the pig ball cover made of PP material, resulting in a reduction in the service life of the pig ball cover.

[0004] To this end, the utility model provides an automatic launching station with an EPDM buffer device. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 and Figure 2The utility model provides a technical solution: an automatic launching station with an EPDM buffer device, comprising a main body tube 1, a push rod gas rod 4 is installed on the lower side of the main body tube 1, a push rod 6 is slidably fitted in the main body tube 1, the push rod 6 corresponds to the push rod gas rod 4, a screw 10 is installed at one end of the push rod 6, a buffer pad 8 is installed on the screw 10, the buffer pad 8 is made of EPDM rubber material, and the buffer pad 8 is in contact with the push rod 6.

[0021] In this embodiment, an air intake pipe 2 and a waste outlet 3 are provided on the main tube 1, a sealing chuck 5 is installed between the main tube 1 and the push rod gas rod 4, a sliding channel 9 is provided in the push rod gas rod 4, the sliding channel 9 corresponds to the push rod 6, one end of the push rod 6 is located in the sliding channel 9, and a push rod piston 7 is fixed to the end of the push rod 6 located in the sliding channel 9, and the push rod piston 7 corresponds to the sliding channel 9.

[0022] Specifically, the push rod 6 can be pushed to slide by the push rod gas rod 4, so that the push rod 6 pushes the pipe cleaning device, thereby performing pipe cleaning.

[0023] The screw 10 includes a nut 11 and a screw rod 12 , the nut 11 is fixedly connected to the screw rod 12 , the buffer pad 8 is located on the peripheral side of the nut 11 , the buffer pad 8 is fixedly connected to the nut 11 , and a nut 13 is fixed on the push rod 6 , and the nut 13 corresponds to the screw rod 12 .

[0024] Specifically, when the pipe cleaner collides instantaneously, the pipe cleaner contacts the buffer pad 8. The buffer pad 8 made of soft EPDM material has a good buffering effect, thereby preventing the pipe cleaner from being damaged. The buffer pad 8 is coated on the circumference of the nut 11 through the rubber coating process, and then fixed to one end of the push rod 6 through the nut 13 and the screw 12. While ensuring a relatively firm fixation, it is also convenient to replace the buffer pad 8.

[0025] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
