Abstract
The utility model discloses a hygiene level packing seal for a stirring tank. The hygiene level packing seal comprises a packing tank body installed on a stirring shaft. A gap between the packing tank body and the stirring shaft is filled up with packing, the packing is pressed by a press cover, a shaft sleeve is fixedly arranged between the stirring shaft and the packing, an accumulated liquid cavity communicated with the packing is arranged at the bottom of the packing tank body, a partition dam is arranged on one side, close to the stirring shaft, of the accumulated liquid cavity, the partition dam is higher than the accumulated liquid cavity and extends into the shaft sleeve, a draining hole communicated with the accumulated liquid cavity is arranged on the other side of the accumulated liquid cavity, and the draining hole penetrates through the bottom of the packing tank body, and a sealing screw plug is detachably arranged at the draining end of the draining hole. When the hygiene level packing seal is used, the sealing screw plug can be screwed open to clean dirt from the draining hole. Thus, abraded waste dirt is prevented from directly entering the tank, the defect that a packing seal cannot be applied to work conditions with hygiene level requirements is overcome, the hygiene level packing seal can substitute a hygiene level mechanical seal, and equipment manufacturing cost is saved.
Description
Technical field
The utility model relates to a kind of stirred tank accessory, is specifically related to the sanitation-grade packing seal of a kind of stirred tank.
Background technique
The stirred tank top comprises with conventional fillers sealing (referring to Fig. 1) the filler casing 4 that is arranged on stirring shaft 1, is filled with filler 3 between the gap that filler casing 4 and stirring shaft 1 consist of, and compresses by gland 2.The deficiency of this kind structure is: one, in order to reduce friction between filler 3 and stirring shaft 1, can add oiling agent in filler 3, the powder that can cause greasy dirt and stirring shaft or filler to wear and tear to get off directly enters in still, thereby material in the pollution still causes packing seal can not be used in the operation operating mode of sanitation-grade requirement.Two, to reveal in order preventing, must to press filler, so just aggravate and the wearing and tearing of the stirring shaft that filler directly contacts, reduced the normal service life of stirring shaft.Although the heat treatment after can completing by fine finishing improves the surface hardness at stirring shaft sealing position and increases the service life, and is due to the very difficult assurance of the straightness accuracy of long stirring shaft after heat treatment, difficult technically.In fact for save cost also seldom manufacturer surperficial cure process is carried out at stirring shaft sealing position, often can cause unavoidably the wearing and tearing of sealing place stirring shaft, thereby reduce the normal service life of stirring shaft.
The stirred tank top determined in the operating mode that has sanitation-grade to require with the shortcoming of conventional fillers sealing, even the not high requirement of pressure is arranged, often also will use the mechanical seal of the sanitation-grade of high price, this has increased cost undoubtedly.
The model utility content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, long service life is provided, and the stirred tank sanitation-grade packing seal that can use in the sanitation-grade operating mode.
The sanitation-grade packing seal of a kind of stirred tank comprises the filler casing that is arranged on stirring shaft, is filled with filler between the gap that filler casing and stirring shaft consist of, and compresses by gland; Be installed with axle sleeve between described stirring shaft and filler, described filler bottom half is provided with the hydrops cavity that communicates with filler, described hydrops cavity closes on the stirring shaft side and is provided with every the dam, described every height of dam in the hydrops cavity and be deep in axle sleeve, the opposite side of described hydrops cavity is provided with the tap hole that communicates, penetrates the filler bottom half with it, and the exhaust end of described tap hole detachably is equipped with the sealing plug.
Be equipped with seal ring between described axle sleeve and stirring shaft.
The utility model is simple in structure, easy for installation, low cost of manufacture, the powder of lubricated greasy dirt and wearing and tearing can directly fall in the hydrops cavity along axle sleeve, the sealing plug of can regularly outwarding winding is cleared up dirt from drain boles, thereby the useless dirt of having avoided wearing and tearing directly enters in still, the axle sleeve of setting up in addition replaces stirring shaft and filler direct friction, wear and tear to substitute the wearing and tearing of stirring shaft with axle sleeve, and the cost of changing the axle sleeve of wearing and tearing will be far smaller than the cost of the stirring shaft of changing whole wearing and tearing, remarkable in economical benefits.
Description of drawings
Fig. 1 is the structural representation that in prior art, stirred tank seals with conventional fillers.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for explanation the utility model but not for limiting scope of the present utility model.
Referring to Fig. 2, a kind of stirred tank sanitation-grade packing seal that the utility model provides comprises the filler casing 4 that is arranged on stirring shaft 1, is filled with filler 3 between the gap that filler casing 4 and stirring shaft 1 consist of, and compresses by gland 2; Be installed with axle sleeve 5 between described stirring shaft 1 and filler 3, be equipped with seal ring 6 between this axle sleeve 5 and stirring shaft 1, can prevent that the air pressure that seals from revealing from the gap between axle sleeve and stirring shaft; Described filler casing 4 bottoms are provided with the hydrops cavity 7 that communicates with filler 3, described hydrops cavity 7 close on stirring shaft 1 side be provided with filler 3 one every dam 8, described every dam 8 higher than hydrops cavity 7 and be deep in axle sleeve 5, the opposite side of described hydrops cavity 7 is provided with the tap hole 9 that communicates, penetrates filler casing 4 bottoms with it, and the exhaust end of described tap hole 9 detachably is equipped with sealing plug 10.The lubricated greasy dirt that filler 3 is revealed and the powder of wearing and tearing directly fall in hydrops cavity 7 along axle sleeve 5, and the sealing plug 10 of can regularly outwarding winding is from tap hole 9 cleaning dirts, thereby the useless dirt of having avoided wearing and tearing directly enters in still.
Claims (2)
1. stirred tank sanitation-grade packing seal, comprise the filler casing that is arranged on stirring shaft, be filled with filler between the gap that filler casing and stirring shaft consist of, and compress by gland, it is characterized in that: be installed with axle sleeve between described stirring shaft and filler, described filler bottom half is provided with the hydrops cavity that communicates with filler, described hydrops cavity closes on the stirring shaft side and is provided with every the dam, described every height of dam in the hydrops cavity and be deep in axle sleeve, the opposite side of described hydrops cavity is provided with it and communicates, penetrate the tap hole of filler bottom half, the exhaust end of described tap hole detachably is equipped with the sealing plug.
