Background technique
Reaction kettle is widely used in the production fields such as petroleum, chemical industry, rubber, pesticide, dyestuff, medicine, food, is to be used for
At the container of the technical process such as various chemical reactions or physical mixed.Reaction mass can be made uniformly to contact by agitating device,
Exposure rate is reacted to strengthen, improves reaction efficiency.Equipment currently used in the market because seal it is poor, when often result in equipment operation
Abnormal or powdered substance is easy to block on bearing, and the powder of nigrescence is even more to be scattered in the feed, brings very to production
Therefore big quality problems, especially medical production equipment, drug can be contaminated, not can guarantee the quality of product.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of reaction kettle axis sealing device, easy to process, sealing
The good, long service life of property.
In order to solve the above-mentioned technical problem, this application discloses a kind of reaction kettle axis sealing device, including it is axle sleeve, described
Gripping sleeve on the outside of axle sleeve, the gripping sleeve are in two halves formula, sealing ring are equipped between the axle sleeve and agitating shaft, in the axle sleeve
It is equipped with end cap with gripping sleeve top, gasket is equipped between the end cap and the axle sleeve and gripping sleeve, outside the gripping sleeve
Side upper end is equipped with thread segment, and the end cap and the clamping set upper side screw fixation；In the case where the gripping sleeve outer lower portion is equipped with
Thread screws tightening nut at the lower thread.
Further, the length of the thread segment of the gripping sleeve outer upper end is greater than matching on the inside of the end cap
Screw thread length.
Further, on the end cap inner sidewall thread segment length be less than the end cap inner sidewall length, institute
It is smooth to state thread segment upper inside wall, length is equal to the sealing mat thickness.
Further, the lower thread bottom end is flushed with the gripping sleeve bottom end.
Further, the tightening nut be internal diameter it is identical, the different boss type nut of outer diameter, the tightening nut it is interior
Wall reach is equal to the length of the lower thread.
Compared with prior art, the application has the advantage that is with beneficial effect: the sealing device of the utility model is from water
It square is sealed simultaneously to on vertical direction, wherein the setting of end cap improves the horizontal direction of entire sealing device
Leakproofness, gripping sleeve upper and lower side respectively have nut to screw fixation, conducive to the leakproofness of vertical direction, powder are effectively prevent to leak, and prevent
Only bearing block, extend the service life of equipment, fixed between end cap and gripping sleeve by threaded engagement, gripping sleeve lower end with
Tightening nut screws fixation, good airproof performance, and tightening nut is flexibly connected with gripping sleeve, facilitates adjusting elasticity and replacement part,
Structure is simple simultaneously, easy to process, is suitable for large sealing device and small-sized sealing device.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please are not constituted an undue limitation on the present application for explaining the application.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1. axle sleeves；2. sealing ring；3. gripping sleeve；4. end cap；5. gasket；6. lower thread；7. tightening nut；
8. thread segment.
Specific embodiment
Presently filed embodiment is described in detail below in conjunction with accompanying drawings and embodiments.
As shown in Figure 1, the utility model provides a kind of reaction kettle axis sealing device, including axle sleeve 1, the axle sleeve 1
The gripping sleeve 3 in outside is equipped with sealing ring 2 between the axle sleeve 1 and agitating shaft, the gripping sleeve 3 is in two halves formula, in the axle sleeve
1 and gripping sleeve 3 at the top of be equipped with end cap 4, between the end cap 4 and the axle sleeve 1 and gripping sleeve 3 be equipped with gasket 5, described
3 outer upper end of gripping sleeve is equipped with thread segment 8, and the end cap 4 and 3 upper end of the gripping sleeve screw fixation；Outside the gripping sleeve 3
Side lower part is equipped with lower thread 6, screws tightening nut 7 at the lower thread 6.
Wherein, the setting of end cap 4 improves the leakproofness of the horizontal direction of entire sealing device, and 3 upper and lower side of gripping sleeve is each
There is nut to screw fixation, conducive to the leakproofness of vertical direction, wherein the tightening nut 7 of 3 bottom of gripping sleeve and the gripping sleeve 3 are living
Dynamic connection, the sealing ring 2 being convenient for changing inside the axle sleeve 1 and the axle sleeve 1 of 3 inside of gripping sleeve.
Further, the length of the thread segment 8 of 3 outer upper end of gripping sleeve is greater than the phase of 4 inside of end cap
The length of the screw thread of cooperation certainly will be become smaller using 2 thickness of sealing ring of 4 lower end of rear end cap for a long time, end cap 4 and gripping sleeve 3 it
Between fastness decline, the connection between thread segment 8 by continuing to screw 3 upper end of end cap 4 and gripping sleeve guarantee fastness and
Leakproofness.
Further, on 4 inner sidewall of end cap the thread segment 8 length be less than 4 inner sidewall of end cap length
Degree, 8 upper inside wall of thread segment is smooth, and length is equal to 5 thickness of gasket.
Further, 6 bottom end of lower thread is flushed with 3 bottom end of gripping sleeve.
Further, the tightening nut 7 is that internal diameter is identical, the different boss type nut of outer diameter, the tightening nut 7
Inner thread length is equal to lower 6 length of thread.
One embodiment of the utility model is described in detail above, but the content is only the utility model
Preferred embodiment should not be considered as limiting the scope of the present invention.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should still belong within the patent covering scope of the utility model.
