Detailed Description

The present application is described in further detail below with reference to figures 1-3.

Referring to fig. 1, in the production of lubricating oil, blending operation of base oil and additives needs to be performed in a blending tank 1, after meeting requirements, an oil product enters a filtering system 5 from the blending tank 1 to be filtered, impurities in the oil product are removed, and finally, the filtered clean oil product is filled into an oil bottle or an oil drum through a filling system 6 to complete filling. Because the outlet 11 position of the blending tank 1 is usually arranged at the height of 0-30 cm from the tank bottom, most of insoluble substances in the oil are pumped out from the outlet 11 at the tank bottom when entering the next filtering process, and only a small part of insoluble substances are precipitated at the tank bottom. Especially when the air-blast pulse is adopted for blending, the air flow strongly scours the pipe wall and metal parts in the tank, all precipitates in the tank are stirred and suspended in oil products, the settling velocity and distance of insoluble substances are prolonged, the content of the insoluble substances in the oil products entering the next process is increased, the load of a filtering system 5 is increased, incomplete filtering is easily caused, and the oil product quality cannot be guaranteed.

The embodiment of the application discloses liftable formula outlet pipeline. Referring to fig. 2, 3, the liftable outlet line comprises a flowline group 2 in a tempering tank 1 and a lift assembly 4 located at the upper portion of the flowline group 2.

The oil outlet pipe group 2 includes a fixed pipe 21 fixed at the bottom outlet 11 of the tempering tank 1 and communicating the inside and the outside of the tempering tank 1. The fixed pipe 21 is horizontally disposed. The end of the fixed pipe 21 located outside the tempering tank 1 is used for connection with the filtering system 5.

One end of the fixed pipe 21 inside the tempering tank 1 is disposed at a position near the middle of the tempering tank 1 and is connected with a vertically movable pipe 22 by a rotary joint 24. The rotary joint 24 is horizontally disposed. Both ends of the movable tube 22 in the length direction are bent by 90 °. The ends of the movable tubes 22 are bent in the same or opposite directions. In this embodiment, three movable tubes 22 are arranged from bottom to top, wherein the bending directions of the ends of the lowermost movable tube 22 and the uppermost movable tube 22 are the same, and the bending directions of the ends of the middle movable tube 22 are opposite. The ends of adjacent movable tubes 22 are connected by a rotary joint 24.

The end of the uppermost movable tube 22 is connected to a vertical outlet tube 23 by means of a swivel 24. The bottom end of the outlet pipe 23 is bent 90 degrees and connected with the rotary joint 24.

The density of the movable pipe 22 and the density of the outlet pipe 23 are both larger than that of the oil product, so that the movable pipe 22 and the outlet pipe 23 are positioned below the liquid level in the oil product discharging process.

A pipeline bracket 3 fixed inside the tempering tank 1 is arranged below the fixed pipe 21.

Since the fixed pipe 21 and the outlet pipe 23 are connected with the movable pipe 22 by the rotary joint 24 and the adjacent movable pipes 22 are connected by the rotary joint 24, the movable pipe 22 and the outlet pipe 23 can be lifted to be fully extended in the vertical direction, and the movable pipe 22 and the outlet pipe 23 can be folded and stored on the pipeline bracket 3. When the movable tube 22 and the outlet tube 23 are completely folded, a gap is left between the movable tube 22 and the outlet tube 23 and the tube wall of the blending tank 1.

The lifting assembly 4 comprises a buoy 41 connected to the side wall of the top end of the outlet pipe 23 by means of a connecting line, a wire rope 44 pulling the buoy 41 and out of the top of the tempering tank 1.

The weight of the weight 45 is less than the weight of the float 41.

The two sides of the inner wall of the blending tank 1, which are located at the two sides of the buoy 41 and are deviated from each other, are provided with positioning ropes 411 which are respectively connected with the top end and the bottom end of the blending tank 1 and tightened. A pull rope 412 extending towards the positioning rope 411 is fixed on the side wall of the float 41, and a sliding ring 423 sleeved on the pull rope 412 is fixed at one end of the pull rope 412 far away from the float 41. Under the action of the positioning rope 411, the buoy 41 can only move up and down in the blending tank 1, so that the swinging of the accessory at the liquid level line 12 is avoided, and the influence on the oil outlet pipe group 2 is reduced.

A take-up reel 42 is fixed on the outer wall of the top end of the blending tank 1, and a steel wire rope 44 is wound on the take-up reel 42 so as to complete the change of the direction. The take-up reel 42 simultaneously supports the steel wire rope 44, and friction between the steel wire rope 44 and the blending tank 1 is avoided.

The top corner of the tempering tank 1 is provided with pulleys 43 which are positioned at the two sides of the corner and fixed on the tempering tank 1. The pulley 43 has the same axial direction as the take-up reel 42. Under the support of the pulley 43 and the action of the balancing weight 45, a distance is reserved between the steel wire rope 44 and the outer wall of the blending tank 1, and no friction exists between the steel wire rope 44 and the blending tank 1. The weight block 45 is mainly used to keep the wire rope 44 in a tightened state and judge the degree of liquid level drop.

A winch 46 is fixed to the outer wall of the tempering tank 1 at a position below the weight 45. The bottom end of the counterweight block 45 is fixed with a hanging ring 451. After the hook of the rope on the winch 46 is hung on the hanging ring 451, the buoy 41 can be lifted and fixed above the liquid level line 12 by operating the winch 46, and oil products are prevented from entering the oil outlet pipe group 2 during blending.

The implementation principle of a liftable formula outlet line of the embodiment of this application does: after the blending process of the lubricating oil is completed, the hanging ring 451 on the balancing weight 45 is taken down from the winch 46, the buoy 41 falls and floats on the oil product, the oil inlet of the outlet pipe 23 completely enters the oil product, the oil product is conveyed outwards through the oil outlet pipe group 2, the oil outlet pipe group 2 starts to be folded along with the descending of the liquid level line 12, and the oil inlet of the outlet pipe 23 also descends.

The utility model provides an outlet line of liftable formula, outlet pipe 23's oil inlet and oil liquid level descend in step, it is the higher oil of the superiors ' cleanliness in blending tank 1 to keep out that oil pipe group 2 collects all the time, and the oil below outlet pipe 23's the oil inlet liquid level obtains more settling time at upper oil filtration filling in-process, the insoluble substance in the oil deposits at the tank bottoms gradually, thereby guarantee to extract filterable all oil through subsiding, improve the cleanliness of oil before filtering.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
