Technical Field
The utility model relates to a spiral shell centrifuge technical field crouches, concretely relates to spiral shell centrifuge's for sleeping in conic section rotary drum part.
Background
The horizontal screw centrifuge is a settling equipment with horizontal screw discharging and continuous operation. The working principle of the centrifugal machine is as follows: the rotary drum and the screw rotate at a high speed in the same direction at a certain differential speed, the materials are continuously introduced into a feeding bin of the screw pusher through a feeding pipe, enter the rotary drum after being accelerated, and heavy solid matters are deposited on the wall of 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 section 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. The machine can continuously feed, separate, wash and discharge materials under full-speed operation.
The rotary drum is composed of a straight section rotary drum and a conical section rotary drum, the straight section rotary drum mainly completes separation, the conical section rotary drum is used as a discharge opening to discharge materials, and a large amount of slag materials are discharged from the discharge opening in the discharging process, so that the outer side of the conical section rotary drum continuously rubs with the slag materials, the outer wall of the conical section rotary drum is abraded, and the service life of the rotary drum is shortened.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art not enough, provide a spiral shell centrifuge's for sleeping in conic section rotary drum part, this scheme is through setting up one row of scraper in ejection of compact section for the slag charge that will get rid of scrapes away, makes it avoid direct and conic section rotary drum outer wall friction, thereby has reduced the wearing and tearing volume of rotary drum, has prolonged conic section rotary drum life.
The purpose of the utility model is realized through the following technical scheme:
the utility model provides a spiral shell centrifuge's for sleeping in conical section rotary drum part, includes conical section rotary drum body, conical section rotary drum body small-bore end extends and forms one section of unloading, a plurality of discharge openings are evenly seted up to the section of unloading, it is evenly fixed with a plurality of scrapers along the axial to unload section outer wall.
Because traditional conical section rotary drum discharge opening discharge is a large amount, causes conical section rotary drum and slag charge to form great friction, this scheme introduces the scraper, and scraper itself exceeds conical section rotary drum outer wall to scrape away the slag charge, avoided slag charge and conical section rotary drum outer wall friction, reduced the wearing and tearing volume of conical section rotary drum outer wall, improved life.
Furthermore, the surface of the scraper is sprayed with a layer of tungsten carbide, and the surface hardness of the scraper can be enhanced by adding a layer of tungsten carbide, so that the abrasion loss of the scraper is reduced.
Furthermore, the scraper is provided with a through hole and penetrates through the screw hole through a screw to be fixed on the discharging section.
Furthermore, the through-hole is the counter sink, makes the nut of screw hides in the screw, and the nut hides in the screw can avoid being worn and torn by the slag charge, causes the later stage to dismantle the problem of difficulty.
Furthermore, the scraper is positioned between two adjacent discharge openings, and the scraping effect of the scraper close to the discharge openings is more obvious.
Furthermore, one scraper is fixed at every two discharge openings, and the arrangement mode is that the speed of scraping materials can be improved.
Furthermore, a layer of ceramic patch is adhered to the inner wall of the conical section rotary drum body through an adhesive, and the ceramic patch is arranged to prevent the inner wall of the conical section rotary drum from being abraded.
Furthermore, the ceramic patches are divided into regular polygon ceramic patches and rectangular ceramic patches, the thickness of each rectangular ceramic patch is larger than that of each regular polygon ceramic patch, the rectangular ceramic patches are axially pasted along the inner wall of the conical section rotary drum body to form multiple boundaries, and the regular polygon ceramic patches are pasted in the areas among the rectangular ceramic patches.
Furthermore, the adhesive is Tianshan TS818 wear-resistant ceramic chip epoxy structural adhesive, and the material belongs to 100% cured material and is used for protecting the metal surface and preventing physical wear and chemical corrosion, so that the scheme uses the ceramic composite material not only for the adhesive, but also as a wear-resistant protective layer, and has double effects.
Furthermore, the regular polygon ceramic patches are regular hexagons, and the area of each regular polygon ceramic patch is 2cm2-5cm2The polygonal patch can increase the contact side length between adjacent patches, and can improve the stability of the patch to avoid falling.
The utility model has the advantages that: compare with traditional conic section rotary drum, the improvement point of this scheme lies in that to paste the wearing and tearing that one deck ceramic paster reduces the inner wall at the inner wall, goes out at the outer wall discharge opening and sets up vertical arrangement's scraper for scrape away accumulational slag charge, thereby reduced the wearing and tearing of conic section rotary drum inner and outer wall, prolonged the life of conic section rotary drum.
