The top end of the outer wall surface of the lower return pipe is provided with a circle of liquid receiving disc which is used for receiving condensed water which drips from the conical diffusion pipe, a circle of grooves are arranged in the liquid receiving disc, the outer wall of the lower return pipe is provided with a plurality of overflow holes, the inner ends of the overflow holes are communicated with the interior of the lower return pipe, and the outer ends of the overflow holes are communicated with the grooves.

The overflow hole is 1mm higher than the bottom surface of the liquid receiving plate.

The overflow holes are arranged obliquely downwards from outside to inside, and the inlets at the outer ends of the overflow holes are 1mm higher than the bottom surface of the liquid receiving plate.

The lower end of the lower return pipe is provided with a section of conical shrinkage pipe, and the bottom end of the conical shrinkage pipe is provided with a section of right-angle elbow pipe.

Compared with the prior art, the utility model has the following advantages: through the mode of separating upper bend and lower back flow, reduce pipeline vibration, in time get rid of the gas that blocks simultaneously, promote LAROX filter intake, promote equipment operating efficiency.

Detailed Description

Referring to fig. 1-4, the embodiment is a vibration reduction return pipe device for a LAROX filter, which comprises an inverted U-shaped bent pipe 1, one end of the U-shaped bent pipe 1 is connected to a liquid outlet pipeline of the filter, the bottom of the other end of the U-shaped bent pipe 1 is connected with a section of conical diffusion pipe 2, the diameter of the conical diffusion pipe 2 gradually increases from top to bottom, the lower end of the inner wall surface of the conical diffusion pipe 2 is fixedly connected with a section of straight pipe 8, a lower return pipe 5 is sleeved outside the straight pipe 8, an exhaust gap is arranged between the outer wall of the straight pipe 8 and the inner wall of the lower return pipe 5, at least one exhaust pipe 3 is arranged at the lower end of the outer wall surface of the conical diffusion pipe 2, and the lower end of the exhaust pipe 3 penetrates through the conical diffusion pipe 2 and is communicated with the exhaust gap. In this embodiment, the top end of the outer wall surface of the lower return pipe 5 is provided with a circle of liquid receiving disc 4, the liquid receiving disc 4 is used for receiving condensed water dropped from the conical diffusion pipe 2, a circle of groove 9 is arranged in the liquid receiving disc 4, the outer wall of the lower return pipe 5 is provided with a plurality of overflow holes 10, the inner ends of the overflow holes 10 are communicated with the interior of the lower return pipe 5, and the outer ends of the overflow holes 10 are communicated with the groove 9. The overflow hole 10 is 1mm higher than the bottom surface of the liquid receiving plate 4. In this embodiment, the overflow holes 10 are arranged obliquely downwards from outside to inside, and the inlets at the outer ends of the overflow holes 10 are 1mm higher than the bottom surface of the liquid receiving tray 4. In this embodiment, the lower end of the lower return pipe 5 is provided with a section of conical shrinkage pipe 6, and the bottom end of the conical shrinkage pipe 6 is provided with a section of right-angle elbow 7. The working principle of this embodiment is as follows: when the LAROX filter operates, filtered liquid enters the U-shaped bent pipe 1 from a liquid outlet pipeline and then enters a liquid tank after passing through the lower return pipe 5, the U-shaped bent pipe 1 is separated from the lower return pipe 5 in working engineering, surplus gas in the pipeline is discharged from an exhaust gap between the straight pipe 8 and the lower return pipe 5 and then is discharged through the exhaust pipe 3, steam water partially condensed on the conical diffusion pipe 2 flows into the liquid receiving disc 4 along the wall surface of the conical diffusion pipe 2, and water in the liquid receiving disc 4 flows into the lower return pipe 5 through the overflow hole 10 when reaching the height of the overflow hole 10. After the liquid at the lower return pipe 5 is gathered by the conical shrinkage pipe 6, the liquid forms a stable clockwise vortex shape to flow into the right-angle elbow pipe 7 under the action of gravity, and at the moment, the lower return pipe 5 has no vibration condition because the liquid in the section of pipeline has formed a stable flowing state, so that the filtering quantity of the LAROX filter can be stably and slowly increased to the maximum power which can be started by the equipment; compared with a backflow pipeline of the LAROX filter in the prior art, the function of the LAROX filter is greatly exerted.
