The connection structure between the center hanger and the center mud tank of the center drive suction dredge

Abstract

The invention relates to a connection structure between a central vertical frame and a central mud tank of a center-driven dredge suction machine, comprising a main beam angle steel fixed on the central vertical frame, an upper connecting flange fixed on the bottom end of the main beam angle steel, and a central A connecting rod is fixed on the mud pot, and a lower connecting flange is fixed on the top end of the connecting rod. One bolt connection. The invention greatly improves the stress of the connecting bolts, makes the connection more reliable, reduces the auxiliary tools used during installation, simplifies the installation strength and steps of the equipment, improves the installation efficiency of the equipment, and reduces the installation cost.

Description

technical field [0001] The invention relates to a connection structure of sewage treatment equipment, in particular to a connection structure between a central pendant frame and a central mud tank of a centrally driven dredge suction machine. Background technique [0002] The central drive suction dredger can remove the settled sludge and floating scum in the circular sedimentation tank. The sewage enters the pool through the water distribution pipe pre-buried at the bottom of the annular water inlet tank around the pool, and flows continuously to the center of the sedimentation tank after passing through the retaining skirt. During this process, the floating matter and sediment are separated from the water. [0003] The central pendant is rigidly connected with the rotating arm of the driving device and the central mud tank respectively. When the rotating arm of the driving device rotates, the central pendant also rotates accordingly, and then the central mud tank and other...

Problems solved by technology

Its disadvantage is: since the center mud tank is suspended and rotated when the equipment is running, the installation of the center hanger also requires the use of tools such as jacks or pulleys to make it suspended in the air, which will cause the through hole connected to the center mud tank to be damaged. It is difficult to align, and the shear force on the connecting bolts in the connecting standard parts is not good.

Its disadvantage is: since the center mud tank 5 is suspended and rotated when the equipment is running, the installation of the center pendant 3 also requires the use of tools such as jacks or pulleys to make it suspended in the air, which will cause the connection with the center mud tank 5 It is difficult to align the through holes, and at the same time, the shear force on the connecting bolts in the connecting standard part 9 is not good.
