Abstract
The utility model relates to a kind of outer shroud disc separator dreg discharge device, primarily of at the bottom of vertical shaft, rotary drum body, piston, annular seal space and threaded ring composition, have at the bottom of annular seal space extend outward centered by vertical shaft the first round platform portion, the second round platform portion, the first concave part and the second concave part, first round platform portion and the second round platform portion are supported on the bottom of rotary drum body, second round platform is fixed together by bolt and rotary drum body, the pressure of double thread trim ring at the bottom of annular seal space can well be reduced like this, thus effectively avoid the locking of double thread trim ring at the bottom of annular seal space; The cross sectional shape of the first concave part and the second concave part and the cross sectional shape of piston corresponding position match, and the first concave part and leave free gap between the second concave part and piston, this is to ensure that piston can be freely up and down, the utility model uniform force pressure, longer service life.
Description
Technical field
The utility model relates to a kind of seperator, is specifically a kind of slag-draining device of outer shroud disk centrifuge.
Background technology
The slagging device of outer shroud deslagging disk centrifuge is by rotary drum body, and piston, at the bottom of annular seal space, the parts such as threaded ring form (see figure 1).Piston assembling, in rotary drum body, is assemblied at the bottom of annular seal space on piston, finally with threaded ring by tight for annular seal space base pressure; The general principle of the slagging device deslagging of outer shroud deslagging disk centrifuge is: carry out moving up and down of control piston by the water yield controlling to enter seperator operation water, thus controls the deslagging sealing action of seperator.When seperator deslagging and sealing action, be full of water on the upside of at the bottom of annular seal space, under high speed centrifugation power under effect, be subject to powerful hydraulic coupling at the bottom of annular seal space, part upper inner fillet place stress is concentrated serious.After frequent deslagging action, at the bottom of annular seal space, distortion is serious, and by threaded ring locking, directly cause threaded ring to be difficult to dismounting, the equipment that affects normally uses.
Utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides the slag-draining device of the outer shroud butterfly seperator of a kind of uniform force pressure, longer service life.
In order to solve above technical problem, the utility model provides a kind of outer shroud disc separator dreg discharge device, primarily of vertical shaft, rotary drum body, piston, at the bottom of annular seal space and threaded ring composition, rotary drum body is socketed on vertical shaft, piston bush is connected at the bottom of annular seal space, under the cooperation of threaded ring, the bottom of rotary drum body is assemblied at the bottom of annular seal space, there is at the bottom of annular seal space the first round platform portion extended outward centered by vertical shaft, second round platform portion, first concave part and the second concave part, first round platform portion and the second round platform portion are supported on the bottom of rotary drum body, second round platform is fixed together by bolt and rotary drum body, the pressure of double thread trim ring at the bottom of annular seal space can well be reduced like this, thus effectively avoid the locking of double thread trim ring at the bottom of annular seal space, the cross sectional shape of the first concave part and the second concave part and the cross sectional shape of piston corresponding position match, and the first concave part and leave free gap between the second concave part and piston, this is to ensure that piston can be freely up and down.
The technical scheme that the utility model limits further is:
Further, be provided with drainage hole at the bottom land of the first concave part, unnecessary water can drain by drainage hole, and the hydraulic coupling that part is subject to reduces greatly, the design of this place improves the force-bearing situation of part greatly, well solves the problem of distortion at the bottom of annular seal space.
Further, be provided with reinforcement in the junction in the first concave part and the second round platform portion, this is because find that this place's stress is concentrated serious in actual use, set up reinforcement can well improve the bulk strength at this place.
The beneficial effects of the utility model are: the utility model is out of shape a serious difficult problem in actual use by can well solve the local improving of existing product at the bottom of annular seal space, greatly can improve the service life of whole equipment.

Detailed description of the invention
embodiment 1
A kind of outer shroud disc separator dreg discharge device that the present embodiment provides, as shown in Figure 3-4, primarily of vertical shaft f, rotary drum body a, piston b, c at the bottom of annular seal space and threaded ring d forms, rotary drum body a is socketed on vertical shaft f, piston b is socketed on c at the bottom of annular seal space, c at the bottom of annular seal space is assemblied in the bottom of rotary drum body a under the cooperation of threaded ring d, c at the bottom of annular seal space has the first round platform portion c1 extended outward centered by vertical shaft f, second round platform portion c2, first concave part c3 and the second concave part c4, first round platform portion c1 and the second round platform portion c2 is supported on the bottom of rotary drum body a, second round platform portion c2 is fixed together by bolt e and rotary drum body a, the pressure of c double thread trim ring d at the bottom of annular seal space can well be reduced like this, thus effectively avoid the locking of c double thread trim ring d at the bottom of annular seal space, the cross sectional shape of the first concave part c3 and the second concave part c4 and the cross sectional shape of piston b corresponding position match, and leave free gap between the first concave part c3 and the second concave part c4 and piston b, and this is to ensure that piston can be freely up and down, drainage hole M is provided with at the bottom land of the first concave part, unnecessary water can drain by drainage hole M, the hydraulic coupling that part is subject to is by hydraulic coupling P(Fig. 2 of original L length) be reduced to the hydraulic coupling (Fig. 4) being subject to L1 length, the design of this place improves the force-bearing situation of part greatly, well solves the problem of distortion at the bottom of annular seal space, be provided with reinforcement in the junction in the first concave part and the second round platform portion, this is the stress concentration status in order to improve this place N point, improves the bulk strength of equipment.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
