Description

Technical Field

[0001] This utility model relates to the field of centrifuge equipment technology, specifically to an automated backflush centrifuge. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids with different densities in emulsions; they can also be used to remove liquid from wet solids, such as in a washing machine to spin-dry wet clothes; special high-speed tubular centrifuges can also separate gas mixtures of different densities; taking advantage of the different settling velocities of solid particles of different densities or sizes in liquids, some sedimentation centrifuges can also classify solid particles according to density or particle size.

[0003] In existing centrifuges, after centrifuging materials, the centrifuged materials are scraped off by a scraper and fall into the collection hopper before being discharged. During the discharge process, when the discharge volume is large, it can cause material congestion, thereby affecting the overall output of the centrifuge.

[0004] The applicant has been a professional centrifuge manufacturer for many years. After a long period of research, it was found that the above-mentioned technical problems can be solved by adding a backflushing system, thereby ensuring the reliability of the equipment. Utility Model Content

[0006] A backflushing centrifuge with anti-clogging features includes a centrifugal device, which is the core component of this invention. The centrifugal device comprises a housing, a drive motor, a spiral feeder, a rotating drum, a bearing chamber, a scraping device, a cover, a hydraulic cylinder, a transmission system, and a cover support plate. The drive motor is mounted on the housing and drives the rotating drum to rotate via the transmission system. The cover is movably mounted on the upper part of the housing via the cover support plate, which is connected to the upper part of the hydraulic cylinder. The lower part of the hydraulic cylinder is movably mounted on the housing via a rotating shaft. The spiral feeder and scraping device are mounted on the cover. The feeder is used to spirally distribute the material onto the rotating drum for centrifugal motion. The scraper is used to scrape the material after centrifugation. The machine cover is also equipped with a feed pipe and a water washing pipe. The feed pipe is used to feed the material, and the water washing pipe is used to clean the entire equipment. The lower part of the shell is equipped with a collection hopper for collecting centrifuged material. The lower part of the collection hopper is equipped with a discharge pipe. The shell is equipped with a drain pipe, the lower part of which is connected to the main drain pipe. The lower part of the main drain pipe is equipped with a manual valve and an electric valve. The lower part of the electric valve is equipped with a hose, which is connected to the mother liquor tank.

[0007] The core improvement of this utility model lies in the back-blowing pipeline provided between the drum and the hopper. The lower left and right sides of the back-blowing pipeline have symmetrical purging holes for purging the material. The back-blowing pipeline is connected to a blower, which provides purging force to the back-blowing pipeline. The back-blowing pipeline can also be connected to a nitrogen inlet pipe to provide nitrogen purging. The back-blowing pipeline is made of metal or engineering plastic. To ensure the service life of the equipment, the material of the back-blowing pipeline is preferably metal.

[0008] Preferably, in order to achieve a better purging effect, the backflush pipeline has an arc-shaped structure in the middle and a horizontal structure on both sides.

[0009] Preferably, in order to achieve the shock absorption effect, a set of shock absorption devices is provided at the lower part of the centrifugal device, which is used to connect with the base to form a buffer.

[0010] Preferably, in order to prevent the equipment from suddenly stopping during use and causing leakage, the discharge pipe is provided with a drain port, and the discharge pipe is also provided with an inclined feeding port connected to the drain port. One side of the discharge pipe is movably connected to a baffle through a rotating shaft, and the baffle is connected to the front of the cylinder.

[0011] The present invention has the following effects: Through the structural design of the present invention, it can ensure that the material does not get blocked during the feeding process, and ensure that the centrifuge works in an orderly manner. In practical application, the effect is significant and it is suitable for widespread promotion and application. Attached Figure Description
