The main motor drives the belt pulley to transfer the power to the drum through the triangle belt, making the drum rotate around its axis at high speed, generating centrifugal force field. At the charging speed, the material feed pipe enters the drum and distributes evenly in the drum. After the drum feed reaches the volume, the material level controller acts to stop the feed, and the solid material separated in the centrifugal force field moves to the drum wall at high speed and finally settles, until the liquid phase settles After the cleaning meets the requirements, the rotating drum speed is reduced to the skimming speed, the clarified liquid is skimmed out through the skimming device, and then discharged out of the machine through the liquid discharge pipeline, the solid phase is left inside the rotating drum, forming the filter cake and finally the drum is turned to the discharge speed (30=100rmi), the scraper starts to scrape, the filter cake is scraped down, the solid phase is discharged through the centrifuge discharge port, and the scraper rises back to the initial position The cycle process is complete.
The machine is designed and manufactured for the large amount of solids in the material liquid, fine particles, and difficult to filter, and the material is easy to oxidized, thermal, and photosensitive. It is mainly used for tympanic fluid separation in the hypertonic state, especially for materials with large viscosity and small particle size for biopharmaceutical, plant extraction, and other industries.

The above purpose is achieved in this way: it comprises a flat plate, the bottom of the plate is fixed with a shock absorber, the motor is installed on the plate, the drum is installed on the drum shaft, the drum shaft is installed on the plate through the bearing, the pulley on the motor power output shaft is connected with the pulley on the drum shaft through the belt, the bottom of the drum is provided with a material outlet; It is characterized by: the plate is also provided with an open-cover control motor, the output shaft of the open-cover control motor is fixed with a connecting plate, the shell outside the drum is connected with the other end of the connecting plate, the top of the shell is provided with a long hole, the open-cover control motor work, can drive the shell to rotate 90°, so that the shell is opened or closed, the shell is provided with a skimming device and a scraper device.
The skimming device comprises a skimming pipe and a skimming base, the skimming pipe front end through a long hole on the top of the shell into the drum, the skimming pipe from the back end of the skimming base, the skimming pipe is fixed on the shell, the skimming pipe is provided with threads on the outer wall between the skimming pipe and the skimming base, the first half of the outer wall is fixed with a ring boss, that is, the first half of the pipe is large in diameter. The second half is small in diameter, the silk master is installed in the skimmer holder, in which the ring boss on the silk master and the skimmer holder inner wall sliding contact, the lower half of the silk master protruding from the skimmer holder, also includes the ring gland, the ring gland is fixed in the back end of the skimmer holder, the ring gland inner wall and the lower half of the silk master sliding contact, located behind the ring gland is fixed on the hand wheel, The rear of the handwheel is provided with a nut, and the nut is fitted with the skimmer pipe thread.
The scraper device comprises a scraper seat, the scraper seat is fixed on the shell, the cylinder body of the scraper lifting cylinder is fixed on the scraper seat, the lower part of the cylinder rod of the scraper lifting cylinder is fixed with a transmission block, the scraper shaft is provided with a transmission block installation slot, the lower part of the scraper lifting cylinder rod transmission block is installed in the transmission block installation slot of the scraper shaft. The transmission block is in sliding contact with the wall of the installation groove of the transmission block, the lower end of the scraper shaft is extended into the rotating drum, the scraper is installed on the lower end of the scraper shaft, and the scraper lifting cylinder drives the scraper to move up and down; Also includes a scraper rotating cylinder, the cylinder body of the scraper rotating cylinder is fixed on the scraper seat, the cylinder rod of the scraper rotating cylinder is connected with a rack, the outer wall of the scraper shaft is opened with a long keyway, the scraper shaft is provided with a gear, the scraper shaft is in sliding contact with the inner wall of the gear, the gear is engaged with the rack, the gear is fixed with a key, and the fixed key on the gear is inserted into the long keyway on the scraper shaft, The scraper rotating cylinder works, driving the rack to extend or retract, the rack movement drives the gear to rotate, because the key on the gear is inserted into the keyway of the scraper shaft, so the gear rotation drives the scraper shaft to rotate.
A sliding sleeve can be arranged between the scraper shaft and the gear, the scraper shaft is in sliding contact with the sliding sleeve, and the sliding sleeve is fixed with the gear.
A gear seat can be arranged under the gear seat, the gear is placed on the gear seat, and the gear seat is fixed on the scraper seat.
The invention has the advantage that the shell is connected with the output shaft of the open-cover control motor through the connecting plate, so that the shell can be rotated 90° and the rotating drum is completely exposed, which is convenient for cleaning and maintenance of the rotating drum. Due to the skimming device, screw the hand wheel to drive the nut and the master screw to rotate, because the ring gland is fixed on the skimmer holder, the skimmer holder is fixed on the top cover, so the nut and the master screw can only rotate and not move axial-wards, the spinning of the master screw and the nut drive the skimmer pipe to move axial-wards, so that the skimmer pipe completes the process of gradually moving from the center to the rotating drum wall, simple structure and low production cost. Easy maintenance. Due to the scraper device, the scraper lifting cylinder is controlled by the scraper lifting cylinder, and the scraper swinging is controlled by the scraper rotating cylinder. The material pasted on the drum wall can be automatically scraped clean, the scraping speed is fast, and the working efficiency is high.
