[0002] In the conveying process of solid-liquid mixed fluid, the problem of sediment accumulation in pipeline is often faced. With the passage of time, solid particles gradually deposit in the pipeline, which not only reduces the effective flow area of the pipeline, increases the resistance of fluid conveying, causes the conveying efficiency to decrease, but also can cause serious consequences such as pipeline blockage. The traditional system and method for preventing pipeline deposition often have many limitations, for example, regular manual cleaning of the pipeline is costly and inconvenient to operate, and needs to pause the conveying operation, which affects the production progress. Some simple flushing devices may not effectively remove stubborn sediments, or may greatly interfere with the ratio of the conveyed solid-liquid mixed medium during the flushing process, thereby affecting the product quality. Therefore, there is an urgent need for an efficient, automated and anti-deposition solid-liquid mixed fluid conveying pipeline system and method that can avoid adverse effects on the conveying medium.

[0024] The present application will be described in more detail by the following preferred embodiments with reference to the drawings so that its technological contents can be made clearer and more easily understood. The present application can be embodied in many different forms and the scope of the present application is not limited to the embodiments mentioned herein.

[0025] In the drawings, components of the same structure are denoted by the same reference numerals, and components having similar structures or functions are denoted by similar reference numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present application is not limited to the size and thickness of each component. In order to make the drawings clearer, the thickness of the components is appropriately exaggerated in some places in the drawings.

[0026] As Figures 1-2 shown, according to the deposition-preventing solid-liquid mixed fluid delivery pipe system of the present application, a flushing pipe 2 is provided beside the solid-liquid mixed fluid delivery pipe 1. The flushing pipe 2 is preferably provided in parallel with the solid-liquid mixed fluid delivery pipe 1, and is filled with fluid for flushing, generally water. A flushing branch pipe 3 is provided every certain distance between the solid-liquid mixed fluid delivery pipe 1 and the flushing pipe 2. A one-way stop valve 4 is provided between the solid-liquid mixed fluid delivery pipe 1 and the flushing pipe 2. The one-way stop valve 4 is maintained in a normally closed state by a torsion spring 6. A flushing valve is provided on the flushing branch pipe 3, and in the embodiment shown in the drawings, the flushing valve has a valve core 5, and the opening and closing of the valve can be realized by 90° rotation of the valve core 5.

[0027] As Figures 3-4As shown, in order to ensure the impact of the scouring water flow, the utility model discloses a kind of driving mechanism that can realize the instantaneous action of valve core 5 for the scouring valve.The driving mechanism includes motor 7.The output gear 8 of motor 7 and large gear 9 cooperate.The outer end of coil spring 10 is fixed on large gear 9.The inner end of coil spring 10 is fixedly connected with the shaft of worm 11.Worm 11 cooperates with pinion 12.Pinion 12 is connected to valve core 5 at one end, and is connected to swing lever 13 at the other end.In the embodiment, swing lever 13 has four rod heads 21 spaced 90 °.The driving mechanism further includes at least one limit block 14, but preferably two limit blocks 14 are arranged symmetrically at 180 ° as in the embodiment.Limit block 14 is provided with limit slot 22 for accommodating rod head 21.Limit slot 22 is flanked by front protrusion 15 and rear protrusion 16, and the height of rear protrusion 16 is greater than that of front protrusion 15.Limit block 14 is telescopically mounted on limit block seat 19 by spring 18 and screw knob 17.The degree of compression of spring 18 can be adjusted by screw knob 17, thereby adjusting the elastic force to be overcome for retracting limit block 14.

[0028] When flushing is required, motor 7 rotates, driving large gear 9 to rotate.When large gear 9 rotates, coil spring 9 is tightened to store energy, while applying torque to worm 11.Worm 11 then transmits torque to swing lever 13 through pinion 12.When the torque generated by the stored energy of coil spring 9 is sufficient to overcome the resistance of rear protrusion 16 of limit slot 22, rod head 21 comes out of limit slot 22, swing lever 13 rotates 90 °, rod head 14 overcomes the resistance of front protrusion 15, and enters the limit again, while pinion 12 drives valve core 5 to rotate 90 ° as well, causing valve core 5 to open rapidly, so that the scouring water flow of scouring pipe 2 rushes into solid-liquid mixed fluid conveying pipe 1 to form impact water flow, and flushes the solid deposits therein.

[0029] When worm 11 rotates, coil spring 9 is also released.When motor 7 continues to rotate, the above process occurs again, and rod head 14 rotates 90 ° again, causing valve core 5 to close.

[0030] Due to the self-locking of worm 11, the driving mechanism will not reverse.

[0031] The rotation of motor 7 is controlled by a controller for timed cleaning.The controller can be networked for centralized control from a remote control room.

[0032] Solar panels 20 can be used to power the driving mechanism.

[0033] The intermittent and staggered on-off valves of multiple scouring branch pipes 3 can flush the deposits in the conveying pipe without significantly affecting the medium ratio of the conveying.

[0034] The preferred embodiments of the present application are described in detail above. It should be understood that those skilled in the art can make many modifications and changes without creative work according to the concept of the present application. Therefore, any technical solutions obtained by logical analysis, reasoning or limited experiments on the basis of the prior art according to the concept of the present application shall be within the protection scope defined by the claims.
