Connection structure of suction disc pipeline

Abstract

The invention relates to a connection structure of a suction disc pipeline, which is used for a fiber filter cloth back-suction device in filter cloth and filter tank equipment of a sewage treatment plant. One end of a suction disc hose is connected with a filter disc suction pipe; the other end of the suction disc hose is connected with a backwashing water pipe; the backwashing water pipe is fixedly arranged on a filter tank wall through a bracket; a wall penetrating waterproof sleeve is arranged in the filter tank wall; a discharging pipe is arranged in the wall penetrating waterproof sleeve; an elbow is welded with one end of the discharging pipe; a connector is welded at the other end of the elbow; a barb structure end of the connector is inserted into one end of a connection hose; an inserting part of the connector and the connection hose is fastened by a hoop; the barb structure end of the backwashing water pipe is inserted into the other end of the connection hose; and the inserting part of the backwashing water pipe and the connection hose is fastened by a hoop. By improving the structure of one end of the backwashing water pipe, additionally arranging the connector and the hoops and utilizing the connection hose to realize soft connection, the connection structure is safe and reliable, the cost of equipment is reduced, the adaptability of the equipment is enhanced and field installation conditions needed by the equipment are sufficiently met.

Description

Technical field [0001] The invention relates to a pipe structure used in a fiber filter cloth anti-suction device in a filter cloth filter equipment of a sewage treatment plant. The invention particularly relates to a suction cup pipe connection structure. Background technique [0002] Suction cup pipes are currently widely used in filter cloth filter equipment in sewage treatment plants, used in fiber filter cloth anti-suction devices, to clean the fiber filter cloth and ensure the filtering capacity of the filter cloth. [0003] At present, the commonly used suction cup pipe connection method is such as figure 1 , figure 2 with image 3 As shown, the filter suction cup 1 is connected to the backwash water pipe 4 through the suction cup hose 2, and the backwash water pipe 4 is welded with the 90° welded elbow 5 and the outer drain pipe 6, and then passes through the wall waterproof sleeve 7 to the outside of the filter . The backwash water pipe 4 is fixed on the wall of the filt...

Problems solved by technology

In this way, not only all the connection methods are hard connections in the form of welding, but also because it involves the coordination of the equipment and the position of the wall-penetrating waterproof sleeve 7 of the civil foundation, when the position of the wall-penetrating waterproof sleeve 7 changes greatly, the entire set of suction cup pipes The hard connection method will not meet the installation requirements of the equipment. At this time, it is necessary to ask the civil engineering foundation to rework the 7 position of the through-wall waterproof casing, which will delay the construction period of the equipment and waste unnecessary costs.
