Description

Technical Field

[0001] The utility model relates to the technical field of discharging control, in particular to a discharging anti-splashing mechanism for a sedimentation centrifuge. Background Art

[0002] A decanter centrifuge is a centrifuge that realizes the centrifugal sedimentation process. During operation, the suspension forms an annular liquid layer along the drum wall under the action of centrifugal force, in which the solid particles with higher density settle radially onto the drum wall to form sediment, and the clarified liquid is discharged through the overflow port of the drum.

[0003] When the clarified liquid is discharged from the overflow port of the drum, the clarified liquid itself has a certain pressure at this time. At the same time, there is a certain height difference between the outlet of the discharge pipe and the top feed port of the storage container. Therefore, when the discharge pipe valve is opened, the liquid is easy to splash out from the discharge pipe, and the splashed liquid will scatter all over the ground, resulting in liquid waste. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a sedimentation centrifuge discharge splash prevention mechanism, including a telescopic part, the telescopic part includes a telescopic pipe, the end of the telescopic pipe can move along the axial direction of the telescopic pipe, and the telescopic pipe can be connected to the discharge pipe mouth of the sedimentation centrifuge.

[0005] By pulling the end of the retractable pipe that is not connected to the discharge pipe so that the end is extended into the storage container, the liquid outlet is prevented from being above the storage container, which would cause liquid to splash out of the discharge pipe easily. The splashed liquid would scatter all over the ground, causing liquid waste.

[0006] Furthermore, the splash-proof mechanism also includes an adjusting component, which can drive one end of the telescopic pipe to move along its axial direction.

[0007] Furthermore, a first connection plate and a second connection plate are respectively fixed at both ends of the telescopic pipe;

[0008] The adjustment component includes

[0009] A fixing portion, the fixing portion being fixed on the first connecting plate;

[0010] A connecting part, wherein a screw part threadably connected to the fixing part is provided at one end of the connecting part, and the connecting part moves along the axial direction of the telescopic pipe by rotating the screw part; and

[0011] A scissor-type telescopic frame, wherein the two groups of connecting rods at the starting end of the scissor-type telescopic frame are pivotally connected to the fixed portion, the above-mentioned connecting portion is pivotally connected to the connecting node of the two groups of connecting rods cross-arranged with the scissor-type telescopic frame, and the ends of the two groups of connecting rods at the end of the scissor-type telescopic frame are provided with connecting blocks, which are pivotally connected to the ends of the two groups of connecting rods at the end of the scissor-type telescopic frame, and the connecting block is fixedly connected to the above-mentioned second connecting plate.

[0012] By rotating the screw part, the connecting part moves along the axial direction of the telescopic pipe, thereby driving the scissor-type telescopic frame to extend and retract, and then driving the end of the telescopic pipe to move along its axial direction, which is easy to adjust and can reduce the shaking amplitude of the telescopic pipe during the liquid discharge process.

[0013] Furthermore, the splash-proof mechanism also includes a docking assembly, which includes

[0014] A connecting pipe, one end of which is provided with a connecting ring, the connecting pipe is fixed to the first connecting plate so that the connecting pipe is connected to the telescopic pipe, and the other end of the connecting pipe is provided with a fixing ring;

[0015] a rotating part, which is sleeved on the outside of the connecting pipe and can rotate along the circumference of the connecting pipe; and

[0016] The pressing part is pivotally mounted on the above-mentioned fixed ring, and the pressing part has an array arranged at equal angles in the circumferential direction. The pressing part of the above-mentioned rotating part is rotated and rotated along the pivot axis between it and the fixed ring to press and fix the connecting pipe and the discharge pipe.

[0017] Furthermore, the docking assembly also includes

[0018] A threaded sleeve, which is sleeved on the connecting pipe and connected to the rotating part; and

[0019] A movable ring is sleeved outside the threaded sleeve and is threadedly connected to the threaded sleeve. The movable ring is connected to the end of the pressing portion through a connecting rod.

[0020] By rotating, the threaded sleeve is driven to rotate, thereby driving the movable ring to move linearly. The pressing part is driven by the transmission of the connecting rod to rotate along the pivot axis between it and the fixed ring, so as to press and fix the connecting pipe and the discharge pipe, thereby realizing quick connection between the splash-proof mechanism and the discharge pipe, which is simple and convenient to implement.

[0021] Furthermore, the docking assembly also includes positioning rods, which are provided in an array and are arranged at equal angles on the outside of the fixing ring along the circumference of the fixing ring.

[0023] Furthermore, the docking assembly also includes a sealing gasket, which is arranged on the surface of the fixing ring.

[0024] The connecting pipe of the splash-proof mechanism is pressed and fixed to the discharge pipe through the pressing part. At this time, the two pipes will squeeze the sealing gasket, and the elastic sealing gasket will be squeezed and deformed, and at the same time, it will react to the end of the pipe, thereby forming a seal between the two pipes and improving the sealing performance.

[0025] The utility model has the following advantages:

[0028] By rotating, the threaded sleeve is driven to rotate, thereby driving the movable ring to move linearly. The pressing part is driven by the transmission of the connecting rod to rotate along the pivot axis between it and the fixed ring, so as to press and fix the connecting pipe and the discharge pipe, thereby realizing quick connection between the splash-proof mechanism and the discharge pipe, which is simple and convenient to implement.

[0029] A limiting groove capable of accommodating the discharge pipe opening is formed by circumferentially arranging an array of positioning rods, thereby realizing rapid positioning of the discharge pipe and improving fixing efficiency.

[0030] The connecting pipe of the splash-proof mechanism is pressed and fixed to the discharge pipe through the pressing part. At this time, the two pipes will squeeze the sealing gasket, and the elastic sealing gasket will be squeezed and deformed, and at the same time, it will react to the end of the pipe, thereby forming a seal between the two pipes and improving the sealing performance.
