Abstract
The utility model discloses a two-way sealing device of a tea rotary barrel. The two-way sealing device comprises a fixed labyrinth ring, a movable sealing ring and a fixed ring. The fixed labyrinth ring is provided with an upper labyrinth channel, a middle labyrinth channel and a lower labyrinth channel and is attached to the inner surface of the rotary barrel. The movable sealing ring is connected with the fixed ring through a first bolt, and the lower end of the movable sealing ring and the lower end of the fixed ring are connected to the surface of the rotary barrel. The movable sealing ring is in tongue-and-groove connection with the middle labyrinth channel of the fixed labyrinth ring. The two-way sealing device has the advantages that axial labyrinth sealing and radial contact sealing are combined, so that the effect of dual sealing is four times that of common sealing.
Description
Technical field
The utility model relates to a kind of tea machinery device, particularly a kind of tealeaves revolving drum bilateral sealing device of good seal performance.
Background technique
In large enterprise's production process, typical tea leaves is that a production line is produced to making finished product from plucking complete later, revolving drum is steps necessary and the flow process for drying, and revolving drum is generally to operate under negative pressure, joint between the device of rotating cylindrical shell and parts and other association need to connect well seamless, therefore, must set seal arrangement in joint.
Basic demand to seal arrangement is:
(1) good seal performance;
(2) can adapt to reciprocal play vertically in the form error (ovality bias etc.) of cylindrical shell and running;
(3) light abrasion, maintenance and maintenance are convenient;
(4) structure is as far as possible simple.
Summary of the invention
The purpose of this utility model is to provide a kind of tealeaves revolving drum bilateral sealing device, combines the dual mode of axial labyrinth seal and radial contact seal, and sealing effect is better, to overcome currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A tealeaves revolving drum bilateral sealing device, comprises
The fixedly labyrinth ring with upper labyrinth channel, middle labyrinth channel and lower labyrinth channel, described fixedly labyrinth ring fits in rotating cylinder surface;
By the first bolted movable sealing circle and retaining ring, described movable sealing circle and retaining ring lower end be connected in rotating cylinder surface;
Described movable sealing circle is that tongue and groove is connected with the middle part labyrinth channel of described fixedly labyrinth ring.
Above-mentioned tealeaves revolving drum bilateral sealing device, the top of described fixedly labyrinth ring is fixed with heat resistant rubber circle by the second bolt, and described heat resistant rubber circle is also connected with the another side of rotating cylinder.
Above-mentioned tealeaves revolving drum bilateral sealing device, is provided with the support ring that supports described heat resistant rubber circle between described heat resistant rubber circle and rotating cylinder surface.
The beneficial effects of the utility model are:
(1) axial labyrinth seal has a plurality of labyrinth channels, and air agitation is few, so sealability is better than general labyrinth sealing;
(2) axial labyrinth seal is combined with radial contact seal, double seal, and effect has reached four times of conventional seals;
(3) movable sealing circle is tongue and groove with middle labyrinth channel and is connected, and therefore labyrinth channel is divided into two, and does not connect each other, more stable than traditional labyrinth channel.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the overall structure schematic diagram of the tealeaves revolving drum bilateral sealing device described in the utility model embodiment.
Embodiment
As shown in Figure 1, a kind of tealeaves revolving drum bilateral sealing device described in the utility model embodiment, comprise fixedly labyrinth ring 1, the cylindrical shell of described fixedly labyrinth ring 1 revolving drum directly contacts and plays the effect of sealing, described fixedly labyrinth ring 1 has upper labyrinth channel 101, middle labyrinth channel 102 and lower labyrinth channel 103, between described upper labyrinth channel 101, middle labyrinth channel 102 and lower labyrinth channel 103, evenly keeps at a certain distance away.
Also comprise movable sealing circle 2 and retaining ring 3, described movable sealing circle 2 is connected by the first bolt 4 with retaining ring 3, described movable sealing circle 2 and described retaining ring 3 lower end be connected in rotating cylinder surface.
The middle part labyrinth channel 102 of described movable sealing circle 2 and described fixedly labyrinth ring 1 is connected for tongue and groove.
Further, the upper labyrinth channel 101 of described fixedly labyrinth ring 1 is fixed with heat resistant rubber circle 6 by the second bolt 5, and described heat resistant rubber circle 6 is also connected with the another side of rotating cylinder.
Further, between described heat resistant rubber circle 6 and rotating cylinder surface, be provided with the support ring 7 that supports described heat resistant rubber circle.
During concrete use, by the first bolt 4, the second bolt 5 and support ring 7, all parts is assembled in to the relevant position on rotating cylinder surface, can realize two-way multi-sealed to the axial mazy type of its position and radial contact, its effect is the more than four times of general sealing.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
