What is a centrifuge machine?
Centrifuge is a machine that uses centrifugal force to separate the components of liquid and solid particles or a mixture of liquid and liquid. Centrifuge is mainly used to separate solid particles from liquid in suspension. Or to separate two different densities of non-soluble liquids in the emulsion. According to the characteristics of different density or particle size of solid particles in the liquid settlement rate, sedimentation centrifuge can classify solid particles according to the density or particle size, the particle size is very small from the liquid phase to separate the solid particles. Centrifuges are widely used in the chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding sectors.
Now the problem with the plate centrifuge?
The existing flat type sedimentation centrifuge after the completion of centrifugal operation, the material paste on the drum wall, need manual scraper, labor intensity, low efficiency, skimming device controlled by the cylinder, complex structure, high production cost. In addition, because the drum is located in the shell, it is not convenient to clean and maintain the drum.
To solve the above problems, we designed the Flat Plate Type Bottom Discharge Sedimentation Centrifuge.
Contents of the invention:
The technical problem to be solved by the invention is to provide a material which can be conveniently and quickly pasted on the wall of the rotary drum with scraper, which is convenient for cleaning and maintenance of the rotary drum and has simple structure of skimming device.
The above purpose is realized in this way: it includes a flat plate, the bottom of the plate is fixed with a shock absorber, the motor is mounted on the plate, the drum is mounted on the drum shaft, the drum shaft is mounted on the plate through the bearing, the motor power output shaft of the pulley and the pulley on the drum shaft is connected by the belt, the bottom of the drum is provided with a discharge port; Its characteristics are: the plate is also provided with a cover control motor, the output shaft of the cover control motor is fixed with a plate, cover outside the shell and the other end of the plate is connected, the top of the shell is provided with a long hole, open cover control motor work, can drive the shell rotation 90 degrees, the shell is opened or closed, the shell is provided with a skimming device and scraper device;
The skimming device comprises a skimming pipe and a skimming seat, the skimming pipe front end through the shell top long hole into the drum, the skimming pipe from the back end of the skimming seat extended, skimming seat fixed on the shell, the skimming pipe is provided with threads on the outer wall between the skimming pipe and the skimming seat is provided with a silk mother, the first half of the outer wall is fixed on the ring boss, that is, the first half of the diameter of the silk mother, The second half is small in diameter, the mother is installed in the skimming seat, which the ring boss on the mother and the skimming seat wall sliding contact, the lower half of the mother from the skimming seat extended, also includes the ring gland, the ring gland is fixed in the back end of the skimming seat, the ring gland wall and the lower half of the mother sliding contact, is located in the back of the ring gland on the mother is fixed on the hand wheel, The rear of the handwheel is provided with a nut, and the nut is installed 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 cylinder rod of the scraper is installed in the transmission block installation slot of the scraper shaft, The transmission block and the wall of the transmission block installation groove sliding contact, the lower end of the scraper shaft extends into the rotary drum, the scraper is installed on the lower end of the scraper shaft, the scraper lifting cylinder work drives the scraper lifting motion; Also includes the 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 the rack, the outer wall of the scraper shaft is provided with a long keyway, the scraper shaft is provided with a gear, the scraper shaft sliding contact with the inner wall of the gear and the rack, the gear is fixed on the key, the fixed key is inserted into the long keyway of the scraper shaft, The scraper rotates the cylinder and drives 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, the gear rotates the scraper shaft.
A sliding sleeve can be arranged between the scraper shaft and the gear, and 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, the gear seat is fixed on the scraper seat.
The invention has the advantages that the shell is connected with the output shaft of the open-cover control motor through the connecting plate, so that the shell can rotate 90° and the drum is completely exposed, which is convenient for cleaning and maintenance of the drum. As a result of the skimming device, screw wheel, drive the nut and screw rotation, because the ring gland is fixed on the skimming seat, the skimming seat is fixed on the top cover, so the nut and screw can only rotate can not carry out axial movement, screw and nut rotation drive skimming pipe for axial movement, so that the skimming pipe completed by the center gradually to the drum wall movement process, simple structure, low production cost, Easy maintenance. Thanks to the scraper device, the lifting of the scraper is controlled by the lifting cylinder of the scraper, and the swinging of the scraper is controlled by the rotating cylinder of the scraper. The material pasted on the drum wall can be automatically scraped clean, with fast scraping speed and high efficiency.
