Adjustable sealing device for pipeline transportation connector

Abstract

The invention discloses an adjustable sealing device for a pipeline transportation connector. The adjustable sealing device comprises a water draining pipe and is characterized in that the interior of the water draining pipe is connected with a main shaft through a bearing, wherein the axis of the main shaft is parallel to the axis of the water draining pipe, a spiral fan is arranged at one end of the main shaft, the outer side of the other end of the main shaft is sleeved with a spiral rod, a spiral plate is arranged on the outer wall of the spiral rod, and a plurality of dredging mechanisms are connected to the spiral plate in a sliding manner; and a dynamic sealing mechanism is arranged outside the water draining pipe, each dredging mechanism comprises a fan-shaped sliding sleeve, the fan-shaped sliding sleeves are connected with the spiral plate in a sliding manner, a sliding sleeve is arranged on the outer side of each fan-shaped sliding sleeve, the sliding sleeves are made of conductive materials, and a first spring is arranged in each sliding sleeve. The adjustable sealing device has the beneficial effects that the adjustable sealing device can automatically adapt to the water using peak period and the water using valley period, dynamic and static sealing is achieved in the pipeline transportation process, and kitchen garbage blocking a pipeline is automatically removed.

Description

technical field [0001] The invention relates to the technical field of pipeline joint sealing, in particular to an adjustable sealing device for pipeline transportation joints. Background technique [0002] In the field of garbage disposal, the disposal of kitchen waste has always been a problem. Not only does it have a high water content, but it also has a high content of oil, salt, and organic matter, and it is easy to carry or breed germs, and it decays very quickly. The meal waste is transported to the fermentation treatment system downstairs through the sewer pipe, and the on-site treatment of the meal waste solves this problem very well. The negative pressure is maintained in the sewer pipe, so that the meal waste in the transportation pipeline can be kept under load. Transported under pressure to the fermentation tank downstairs. However, the length of the pipeline connecting the user's kitchen to the fermentation tank downstairs is often not enough, especially for h...

AI Technical Summary

Problems solved by technology

However, the length of the pipe connecting the user's kitchen to the fermentation tank downstairs is often not enough, especially for high-rise floors. During the installation process, multiple pipes need to be connected. The overall airtightness of the sewer pipe, especially the joint The air tightness affects the negative pressure performance of the entire pipeline. However, the existing sewer pipe joints have a single structure and size, which is difficult to adapt to the peak and trough periods of garbage discharge in the morning, evening and noon. During transportation, such as grease solidification or kitchen paper After absorbing water, it sticks to the inner wall of the pipe, especially when the kitchen waste in the sewer pipe contains hard bones, it is very easy to cause the pipe to be blocked. It takes a lot of manpower and time to disassemble and clear it, and the practicability is poor.
