Abstract
The invention discloses a top seal structure for a separator of a grinding device. The top seal structure comprises a rotor of the separator and a fixed structural member. A gap is arranged between the rotor and the fixed structural member. The top of the rotor and fixed structural member is sequentially provided with a circular wool felt and a circular pressure plate; the end of the circular wool felt extends out to a length to cross and cover the gap. The top seal structure is reasonable in structural design; the covering pattern is adopted mainly, the influence of part machining precision and assembly precision upon sealing effect can be avoided, and the problem that the wool felt wears is solved; a sealing direction is fully perpendicular to a flow direction of material, any powder of unqualified particle size never escapes from the separator through a seal system, the powder of unqualified particle size is thoroughly prevented from escaping from the separator, and the highly strict requirement of material grinding for product particle size is fully met.
Description
technical field:
The present invention relates to grinding processing technique field, relate in particular to a kind of separator top seal structure of milling equipment.
background technique:
At present, the grinding of material is mainly the energy-efficient vertical pulverizing mill of application (including but not limited to vertical roll grinder, Raymond mill, column mill and similar vertical pulverizing mill tool or equipment), and vertical pulverizing mill depends on the separator of vertical pulverizing mill to the classification of material.
The working principle of separator, as shown in Figure 1.
Under the driving of variable-frequency motor 1, speed reducer 2, rotor 4 High Rotation Speeds of separator, risen with the air-flow rotating in separator by the material after grinding, attempt by rotor 4, the underproof granular material of granularity is stopped by the rotor 4 of High Rotation Speed, the inwall discharge of cone bucket 5 certainly, and the granular material that granularity is qualified passes through rotor 4, the exhaust outlet 3 of autogenous tumbling mill is discharged grinding machine with air-flow, thereby realizes the grading function of material.
In the project organization of separator, between the rotor of rotation and static structural member, there is gap A, can cause the underproof granular material effusion of granularity separator, enter in the finished product of grinding machine production, cause the granularity requirements of finished product defective, therefore, must seal gap A.
Traditional end part seal method is, offer the screw of annular distribution at the end face of ring-type static structures part, on this end face, lay the ring-type wool felt with same perforate, the inner-diameter end of ring-type wool felt props up the side of cylindrical body rotor, on wool felt, lay the ring-type pressing plate with same perforate, be finally fixed together by bolt, pad and static structures part.
Traditional only gap and the end part seal mode in gap, be subject to rotor part and the static machining accuracy of structural member and the impact of assembly precision, gap A is impossible uniformity completely at circumferencial direction, the inner-diameter end size of flexible blockage thing cannot be processed to such an extent that fit like a glove with the size of irregular gap A, the inner-diameter end of flexible blockage thing is the side that impossible prop up cylindrical body rotor completely, in other words, adopt after end part seal mode, gap A can not be sealed completely.In addition, the rotor of rigidity is dynamic in rotating, and flexible plug remains static, the inner-diameter end of plug inevitably there will be wearing and tearing, thereby again produce new gap, and the direction in this gap is consistent with the moving direction of material flow again, the underproof granular material of small part granularity is still had an opportunity from this gap location effusion separator.
In a word, in the time that grinding requires extremely harsh material to product granularity, traditional end part seal method of separator, can not seal gap A completely, still can not meet the requirement of product granularity.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide a kind of separator top seal structure of milling equipment, stop up hill and dale the probability of the underproof granular material effusion of granularity separator, meet the requirement that product granularity is required to the grinding of extremely harsh material completely.
Technological scheme of the present invention is as follows:
The separator top seal structure of milling equipment, comprise the rotor of separator and static structural member, between rotor and static structural member, be provided with gap, it is characterized in that: described rotor and static structural member end face are provided with wool felt, the ring-type pressing plate of ring-type successively, the end extrusion of ring-type wool felt across and coverage gap.
The separator top seal structure of milling equipment, is characterized in that: the described end face of static structural member and the end face of rotor maintain an equal level, and the direction of the wool felt sealing of ring-type is vertical with the moving direction of material flow.
Advantage of the present invention is:
Reasonable in design of the present invention, the main coverage mode that adopts, can avoid the impact on sealing effect of component processing precision and assembly precision, solve the wear problem of wool felt, and the direction of sealing is completely perpendicular to the moving direction of material flow, the underproof granular material of any granularity all can not be had an opportunity from sealing system effusion separator, stop up hill and dale the probability of the underproof granular material effusion of granularity separator, meet the requirement that product granularity is required to the grinding of extremely harsh material completely.
brief description of the drawings:
Fig. 1 is the structural representation of separator.
Fig. 2 is structural representation of the present invention.
embodiment:
Referring to accompanying drawing:
The separator top seal structure of milling equipment, comprise the rotor 4 of separator and static structural member 6, between rotor 4 and static structural member 6, be provided with gap A, rotor 4 and static structural member 6 end faces are provided with wool felt 7, the ring-type pressing plate 8 of ring-type successively, the end extrusion of the wool felt 7 of ring-type across and coverage gap A, finally be fixed together with static structural member 6 by bolt 9, pad 10, form new sealing system.
The end face of static structural member 6 and the end face of rotor 4 maintain an equal level, and the direction that the wool felt 7 of ring-type seals is vertical with the moving direction of material flow.
