Description

Novel horizontal spiral filtering centrifuge for cow dung

Technical Field

The utility model relates to a centrifuge technical field specifically is a novel horizontal spiral filter centrifuge is used to cow dung.

Background

Centrifuges are machines that utilize centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. The working principle of the horizontal centrifuge is as follows: the rotary drum and the spiral pusher rotate in the same direction at a certain differential speed, materials are continuously introduced into the spiral pusher through the feed pipe, the materials are accelerated to enter the rotary drum, and heavy solid-phase substances are deposited on the rotary drum to form a slag layer under the action of a centrifugal force field. The spiral pusher continuously pushes the deposited solid-phase substances to the conical end of the rotary drum and discharges the solid-phase substances out of the machine through the slag discharge port. The lighter liquid phase forms an inner layer liquid ring, continuously overflows from the rotary drum through an overflow port at the large end of the rotary drum, and is discharged out of the machine through a liquid discharge port.

A small amount of solid phase particles still can be doped in a liquid phase separated by the horizontal spiral centrifuge in the prior art, and when the horizontal spiral centrifuge is applied to cow dung separation, the separated sewage is inconvenient to further treat. And the filter core can take place to block up after long-time the use for current filter equipment who is applied to screw centrifuge, and the staff then can cause the liquid outlet to block up and influence the liquid dung separation and cause the machine damage even if unable in time discover and change filter core. And in the process of replacing the filter element by a worker, the separated sewage cannot be filtered, and the worker needs to stop to wait for repair, so that the working efficiency is influenced.

Principle of operation

This novel horizontal spiral filter centrifuge is used to cow dung, during the use, starter motor one 6 and motor two 8 send the excrement material into auger delivery 4 inside backs through hollow shaft 5, under the centrifugal force effect that high-speed rotation produced, are thrown into 2 intracavity of rotary drum immediately. The rotary drum 2 rotating at a high speed generates strong centrifugal force to throw and paste solid-phase particles with density higher than that of a liquid phase on the inner wall of the rotary drum 2 to form a solid layer; since moisture has a low density and a low centrifugal force, only a liquid layer, called a liquid ring layer, can be formed inside the solid ring layer. Because the spiral conveyor 4 and the rotary drum 2 have different rotating speeds, namely a rotating speed difference exists between the spiral conveyor 4 and the rotary drum 2, the sludge of the solid ring layer is slowly pushed to the conical end of the rotary drum 2 by the rotating speed difference between the spiral conveyor 4 and the rotary drum 2 and is continuously discharged from outlets distributed on the circumference of the rotary drum 2; liquid in the liquid ring layer continuously overflows from the weir crest by means of gravity and is discharged through the liquid outlet 9 to form separation liquid, so that the liquid dung of the cow dung is separated; the liquid outlet 9 enters the main filter pipe 11 through the electric three-way valve 13, is filtered by the filter 14 in the main filter pipe 11 and then enters the next working procedure through the liquid discharge pipe 15; after filter 14's filter core takes place to block up in the main 11 intraductal filters of filtering, the play liquid end one side liquid flow of filter 14 in the main filter pipe 11 reduces, after the velocity of flow reduces to appointed threshold value, pipeline flow sensor 16 sends signal to controller 17, controller 17 starts 18 work of bee calling organ and reminds the staff to change the filter core, and drive electric three-way valve 13 intercommunication reserve filter pipe 12 and liquid outlet 9, filter 14 through reserve filter pipe 12 filters liquid, thereby avoided leading to liquid outlet 9 to block up because of the staff can't in time change filter 14 filter core and influence the problem emergence that the liquid dung separation even caused the machine to damage.
