Description

A kind of whizzer

Technical field:

The utility model relates to a kind of centrifuge, particularly a kind ofly integrates separation, drying, sterilizes, the pollution-free risk of separated material, without multi-functional a kind of whizzer of Particle Breakage.

Background technology:

At present, centrifuge is widely used in the Separation of Solid and Liquid field in the industries such as pharmacy, chemical industry, the centrifuge that uses at present only has the function of Separation of Solid and Liquid, material after general the separation still contains some moisture content, needing further it to be carried out drying processes, this is with regard to the transfer that has material and the problem such as deposit, and has the contaminated risk of material; Now widely used automatic scraper conveyer centrifugal is that the material scraper after will separating with scraper chips away, and has inevitably the problem of material crushing.

The utility model content:

The purpose of this utility model just provides a kind of whizzer, and it can well overcome the existing problem of above product.

The purpose of this utility model is to realize like this, a kind of whizzer, comprise cover, main shaft and bearing, it is characterized in that: be provided with casing between cover and the bearing housing, the top, outer ring of casing is provided with exhaust outlet, the below of its outer ring is provided with discharging opening, and the below correspondence of exhaust outlet is provided with delivery port; The inwall top of casing is provided with the blowback cavity, and the blowback cavity communicates with air inlet pipe A, and the inwall below of casing is provided with dry cavity, and dry cavity communicates with air inlet pipe B; Chassis cavity middle part is provided with conical rotary drum, and radial equipartition is provided with several through holes on the drum inner wall, and is provided with screen pack thereon, and the outer ring of rotary drum is uniform to be provided with some muscle; One end of rotary drum is provided with the rotary drum stifle, the up and down two ends of rotary drum stifle are passed by air inlet pipe A and air inlet pipe B respectively, hollow spindle in rotary drum stifle and the bearing housing links, and communicates with rotary drum stifle centre bore, and the other end of rotary drum passes rotary drum lid and cover successively by axle; Described bearing housing is by base support.

The utility model from charging, washing, separating and dehydrating, be dried to the whole process of discharging and in airtight space, finish, avoided material contaminated risk in transport process, adopt the blow-back discharging, there is not the problem of Particle Breakage in the machinery-free scraper.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

A kind of whizzer, comprise cover 1, main shaft 12 and bearing 13, it is characterized in that: be provided with casing 3 between cover 1 and the bearing housing 11, the top, outer ring of casing 3 is provided with exhaust outlet 5, the below of its outer ring is provided with discharging opening 15, and the below correspondence of exhaust outlet 5 is provided with delivery port 14; The inwall top of casing 3 is provided with blowback cavity 6, and blowback cavity 6 communicates with air inlet pipe A7, and the inwall below of casing 3 is provided with dry cavity 8, and dry cavity 8 communicates with air inlet pipe B9; Casing 3 inner chambers middle part is provided with conical rotary drum 4, and radial equipartition is provided with several through holes on rotary drum 4 inwalls, and is provided with screen pack 10 thereon, the uniform some muscle 18 that are provided with in the outer ring of rotary drum 4; One end of rotary drum 4 is provided with rotary drum stifle 17, the up and down two ends of rotary drum stifle 17 are passed by air inlet pipe A7 and air inlet pipe B9 respectively, hollow spindle 12 in rotary drum stifle 17 and the bearing housing 11 links, and communicate with rotary drum stifle 17 centre bores, the other end of rotary drum 4 passes rotary drum lid 2 and cover 1 successively by axle; Described bearing housing 11 is by base 16 supportings.

During implementation, the utility model rotary drum lid 2 is to rotary drum 4 motions, with the rotary drum 4 relative airtight spaces of formation and with rotary drum 4 rotations, by 12 rotations of the driving mechanism drive shaft such as motor, after reaching certain rotating speed, through hole in the middle of main shaft 12 injects material to be separated, material through hole of 17 at the bottom of the rotary drum flows into the inner chamber of rotary drum 4, behind reinforced the end, behind rotary drum 4 High Rotation Speeds, under the obstruction of screen pack 10, solid material is trapped on the inwall of rotary drum 4, liquid flows out from the delivery port 14 of casing 3 bottoms, injecting cleaning fluid from reinforced position washs filter cake, after the drying, inject high temperature nitrogen from air inlet pipe B9, diffuse in whole rotary drum 4 inner chambers by dry cavity 8, water evaporates in the material after separating is gone out, steam then drains into outside the machine by exhaust outlet 5, rotary drum 4 reductions of speed, rotary drum 4 forwards suitable position to and stops, two the adjacent muscle 18 that are about on rotary drum 4 outer rings forward blowback cavity 6 position of correspondence on every side to, this moment blowback cavity 6 with rotary drum 4 and adjacent relative airtight cavity of 18 formation of two muscle, at this moment the pulsed nitrogen that passes into high pressure from air inlet pipe A7 blows off the filter cake of rotary drum 4 interior two muscle 18, then rotary drum 4 continues to rotate to an angle and forms a relative airtight cavity with other 18 in two muscle, filter cake in 4 two muscle of rotary drum 18 is blown off, repeat such process until the filter cake in the rotary drum 4 is come off fully, rotary drum 4 slowly rotates, inject the pulsed nitrogen of HTHP from air inlet pipe B9, oppositely seeing through screen pack 10 by dry cavity 8 is blown in the rotary drum 4, the material that has come off is blown pine and dry further, after the end, 2 actions of rotary drum lid, move to cover 1 direction, away from rotary drum 4, continuation passes into high pressure nitrogen in dry cavity 8, rotary drum 4 slow circumvolves make solid material discharge from discharging opening 15 simultaneously, and so far, a work period finishes.
