Discharging and filtering (concentrating) centrifuge under the automatic continuous centrifugal
This machine is a kind of novel centrifugal separation equipment, can realize centrifugal automatically discharging down, both can be used as the centrifugal filtration thickener, also can be used as the centrifugal filtration dewaterer, is widely used among the operation of environmental protection water treatment and various production technology.
At present, this class centrifugal separation equipment in this field has batch (-type) and continous way, the structure of the two, especially running part is all comparatively complicated, the manufacturing cost height, and cause easily that charging is inhomogeneous to cause splashing and impacting of rotary drum vibrations or feed liquid, wherein, the step operating efficiency that obviously is unfavorable for improving equipment needs artificial discharging or adds mechanical drawing mechanism in addition; Continous way except utilizing complicated drawing mechanism, be to utilize rotary drum (cone-element) to make filter residue overcome the friction of asking by the centrifugal force of itself therein with the drum wall, move and draw off voluntarily to the big end of rotary drum, but, the existing equipment of this mode all adopts the rotary drum (cone-element) opening to make progress or side direction, promptly so-called vertical and horizontal (rather than centrifugal discharging down), its transmission system and feed system complexity, easily material folding, and a difficult problem such as running heating is given prominence to.
The design adopts unique axial admission mode, and make it to be uniformly distributed on the rotary drum (cone-element) wall after centrifugal, and Open Side Down for rotary drum (cone-element), to finish the centrifugal centrifugal separation processes of discharge way down, in structure and design, tangible technological break-through is arranged all, meet The Patent Law of the People's Republic of China and relevant law to defining of inventing, therefore with this project application patent of invention.
This design is to solve a prior art difficult problem and to realize that continuous high-efficient production is purpose, be optimized design in many-sides such as art designs, reasonable structure and manufacturing cost, energy consumptions, and make it seriation, realize non-maintaining work, develop into a new height thereby will have this class centrifugal separation equipment now.
This design compared with prior art has tangible advantage and good effect.Its course of work is continuous automatically, and the unique feeding manner and the kind of drive have realized having in the centrifugal technical breakthrough of discharging down
1. axial admission, mode is simple and direct, and feed liquid is evenly distributed rationally, both prevented that the feed liquid skewness from causing the rotary drum vibrations, has prevented feed liquid again to the lateral impact of rotatory drum wall with splash, and the crystal grain destructiveness is littler.
2. adopt direct transmission, do not have friction, need not lubricate, more do not have running heating phenomenon, can realize non-maintaining work.
3. project organization compact and reasonable more, parts are few, and power consumption is low, and manufacturing cost only is about 50% of a prior art equipment.
4. convenient and flexible operation can be changed the rotary drum of different size and tapering in respective range, the serviceability temperature wide ranges is strong to the adaptability of condition of work.
5. be easy to seriation and corrosion protection design.
Accompanying drawing one is the technology contents of discharging and filtering under the automatic continuous centrifugal (concentrating) centrifuge, it be by 1, cover, 2, centrifugal impeller, 3, rotary drum (cone-element), 4, the motor bearing, 5, motor, 6, recovering hopper and 7, support form.After the start, centrifugal impeller and rotary drum (cone-element) that motor-driven has splash guard rotate synchronously, feed liquid enters centrifugal impeller through the upper axial feed pipe, make it the centrifugal rotary drum that enters and begin centrifugal separation processes, and move down along drum inner wall, last residual fraction falls into recovering hopper so that collection and treatment.
The centrifugal distribution of the axial admission of this technology, feed liquid and the design of splash guard and unique drive mechanism design are the best modes of realizing discharging under the automatic continuous centrifugal, wherein topmost also is that necessary part is a centrifugal impeller, and it is double to prevent that the destruction of crystal grain and feed liquid from damaging filter cloth to the lateral impact of drum inner wall.Accompanying drawing two is centrifugal impeller structures, and it is by 1. upper end covers, 2. blade, 3. bottom end cover, the 4. rigid integral body formed of baffle plate and 5. power transmission shafts, it directly links with Motor Shaft, and and the rotary drum (cone-element) small end connect and rotate synchronously; Simultaneously, its central upper portion hole is the charging aperture of centrifugal impeller, and and feed pipe between rational gap is arranged, thereby realize direct transmission, the technical barrier of frictional heating when having solved running.In addition, the cone angle that designs on this part is that the baffle plate and the centrifugal impellers of 36 degree rotate synchronously, the feed liquid that may splash is blocked and once more with its centrifugal getting rid of at drum inner wall, makes it to participate in again centrifugal separation processes.
