Tail gas after reason is expelled to the discharge of 15m discharge drums by rotary-vane vaccum pump, and rotary-vane vaccum pump does not contact directly with waste gas, therefore
Pollution will not be received so that operating efficiency further improves, and rotary-vane vaccum pump.
By a process cycle, the diatomite oil content ＜ 900mk/kg after desorption and regeneration, after the completion of regeneration treatment, go out
Material mouth is controlled by control system carries out deslagging, and after regenerator vacuum breaker, diatomite is pushed into discharging opening by agitating device in regenerator,
Blow-off valve and air inducing induction system are opened simultaneously, then the raw-soil is discharged by discharging opening, is conveyed import into air inducing, is using air-introduced machine
Power, diatomite is stored after the separator separation at the top of pipeline to intermediate storage tank, and eventually through helix transporting device
Diatomite is delivered to electric calcination rotary kiln stove high-temperature roasting.
In the utility model, regenerator includes the laterally disposed and internal metal cylinder for confined space, so as to ensure that
The negative pressure state of internal regenerator, metal cylinder carries out electromagnetic eddy heating by electromagnetic heater, and is arranged in furnace shell,
Electromagnetic heater is in the bottom of metal cylinder, and insulation material is arranged at top, and the stirring structure set in metal cylinder is to diatomite
It is stirred, so as to ensure being normally carried out for desorption and regeneration, the agitating shaft of stirring structure can pass one end or two of metal cylinder
End, because the temperature heated to diatomite has 100~200 DEG C, therefore axle portion friction when being heated if axle portion sealing tension
It is larger, seal bad if axle portion sealing is more loose, vacuum effect is poor, therefore the sealing structure and gold of the utility model particular design
So as to which sealing be solved well with expanded by heating problem, metal cylinder is stirred the position that axle passes through to be had category barrel end structure
Extend mouth, extension is intraoral sealing structure, and sealing structure includes the first sealing ring, the first packing, the second packing, projection, second
The cooperation of sealing ring realize good axle portion sealing effectiveness under different temperatures, and agitating shaft will not be squeezed to obtain into tension,
The annular edge of triangle can limit projection direction into metal cylinder with male cooperation and move, the first sealing ring both sides
First packing and the second packing can realize double-layer seal, and double-layer seal is not common sealing, and both length are different, the
The position that two packings are shorter than the difference of the first packing and length is provided with the second sealing ring, and the second sealing ring compresses the second packing,
So that the second packing is limited in projection, in the space that the first sealing ring, the second sealing ring, agitating shaft surround, because the first sealing
Ring adds the thickness of the second sealing ring to add the thickness of the first sealing ring less than the second packing, therefore even if temperature is higher, also can
Ensure being normally carried out for work, while the first sealing ring is tightly leaned annular edge, the first sealing ring by the second sealing ring
Be step type with the second sealing ring, both sealing rings of ladder height first are lower slightly, therefore work when can be slightly stagger,
Particularly both of which is chosen a position and is fixed on shrouding, and both fixed positions are located above and below agitating shaft respectively,
Therefore in expanded by heating, just can be good at staggering, while sealing effectiveness is also good enough when temperature is lower, in addition, first
The contact surface at both sealing ring and annular edge is inclined-plane, and the contact surface of both the first sealing ring and second sealing ring is oblique
Face so that simple, the rotation of influence agitating shaft again while can tightly withstanding for change of staggering.
Observation visor and extension valve are additionally provided with the utility model, between dephlegmator of top of the tower and condenser, whole
When equipment works, it is necessary to daily artificial detection observation visor could judge whole equipment whether normal operation, but this practicality is newly
Type needs to fractionate out the oil product of different fractions, and the temperature of the temperature particularly dephlegmator of top of the tower of dephlegmator of top of the tower and condenser becomes
Change larger, expand with heat and contract with cold so that device security reduces, particularly observe visor and cause damage, be frequently necessary to more during actual tests
Observation visor is changed, so as to reduce the stability of equipment, prior art is without being fractionated directly condensation, therefore production by oil gas
Product degree of refinement is low, and product is coarse, and the present inventor will increase extension valve between dephlegmator of top of the tower and condenser, so as to well
Device security caused by when fractionating out different oil products when solving different regeneration temperatures is low, and observation visor holds damageable asks
