Abstract
The utility model relates to a novel shaft sealing device and a horizontal concrete mixer thereof, for overcoming the defects of the prior shaft sealing devices such as high lubricant consumption and pollution on internal materials. The shaft sealing device comprises a rotation shaft and a shell, wherein the rotation shaft is provided with a dynamic sealing ring and a static sealing ring, the dynamic sealing ring is fixed on the rotation shaft to rotate together, the static sealing ring and the shell are provided with a spring therebetween, the opposite end faces of the dynamic and static sealing rings are tightly contacted and sealed by liquid. The horizontal concrete mixer adopts the novel shaft sealing device. The shaft sealing device has simple structure and is suitable for various mechanical devices needing shaft sealing device. Adopting the shaft sealing device, the horizontal concrete mixer can attain long service life, eliminate lubricant consumption, prevent oil dirt in concrete and attain high quality.
Description
Technical field
The utility model relates to the horizontal concrete mixer of a kind of novel shaft sealer and application thereof.
Background technique
Rotary shaft mechanism comprises fixed pedestal and rotating shaft at least, and the two is one moving one quiet, inevitable gapped, friction is arranged, generally all carry out necessary lubricated.Some shell of tank (hereinafter to be referred as shell) is exactly a fixed pedestal, and rotating shaft is arranged on the shell, and the material in shell leaks along the gap between rotating shaft and the shell, also will reach the requirement of hermetic seal or liquid sealing between shell and the rotating shaft.
Lubricated by butter between the rotating shaft of existing horizontal concrete mixer and the shell, oil consumption is big, the cost height, and butter can infiltrate concrete, and concrete is polluted.
The model utility content
The technical problems to be solved in the utility model is the defective that the lubrication oil consumption that how to overcome existing shaft sealer pollutes materials inside greatly, easily, and a kind of not oil consumption, pollution-free, novel shaft sealer that the life-span is long and the horizontal concrete mixer of application thereof are provided.
For solving the problems of the technologies described above, this novel shaft sealer comprises rotating shaft and shell, and it is characterized in that: described rotating shaft is provided with rotary packing ring and stationary seal ring, and wherein rotary packing ring is fixed in the rotating shaft, rotates with rotating shaft; Be provided with spring between stationary seal ring and the shell, and can be along the moving axially of rotating shaft, under the effect of spring, the opposing end surface of rotary packing ring, stationary seal ring closely contacts, and liquid sealing.So design, dynamic and static seal ring is selected high abrasion resisting material for use, and the seal face gap control is between 1-2 μ m, and the life-span can reach 30000h (standard working day 10 years) and not consume lubricant oil, and cost of production is low, good product quality.
Concerning the shaft sealer of horizontal concrete mixer, dynamic and static seal ring is as selecting the contour wear-resistant metal material of wolfram steel for use, during work, water can infiltrate between the dynamic and static seal ring, and the vaporization of being heated can be taken away the heat that produces because of friction, can play effect lubricated, cooling, better effects if.
As optimization, be provided with axial guide between described stationary seal ring and the shell.So design, dynamic and static seal ring fiting effect is good.
As optimization, described axial guide is a plurality of equally distributed guide fingers.So design is simple in structure.
As optimization, described shell is provided with protecting jacket, and this protecting jacket is enclosed within the rotating shaft, and the gap structure between itself and the rotating shaft is a labyrinth seal structure.So design can prevent that the large particle solid material from entering between the dynamic and static seal ring, causes unnecessary wearing and tearing on the one hand; Can reduce the osmotic pressure of liquid material on the other hand, strengthen sealing effect to external penetration.
The utility model horizontal concrete mixer comprises shaft sealer, and this shaft sealer is aforementioned novel shaft sealer.
This novel shaft sealer has reduced the grease pump system with respect to original yellow glue seal arrangement, and structure is simpler, is applicable to the various machinery that need shaft sealer.This novel shaft sealer is applied to horizontal concrete mixer, and the life-span is long, does not consume lubricant oil during work, and can not sneak into lubricant oil in the concrete, and quality is good.
Description of drawings
Below in conjunction with accompanying drawing this novel shaft sealer is described further:
Fig. 1 is the part section structural representation (dissecing along shaft axis) of this novel shaft sealer.Among the figure: 1 is that rotating shaft, 2 is that shell, 3 is that rotary packing ring, 4 is that stationary seal ring, 5 is that spring, 6 is that guide finger, 7 is a protecting jacket.
Embodiment
Mode of execution one: as shown in Figure 1, this novel shaft sealer comprises rotating shaft 1 and shell 2, and it is characterized in that: described rotating shaft 1 is provided with rotary packing ring 3 and stationary seal ring 4, and wherein rotary packing ring 3 is fixed in the rotating shaft 1, rotates with rotating shaft 1; Be provided with 9 between stationary seal ring 4 and the shell 2 along the equally distributed spring 5 of circumference, stationary seal ring 4 can be along the moving axially of rotating shaft 1, and under the effect of spring 5, the opposing end surface of rotary packing ring 3, stationary seal ring 4 closely contacts, and liquid sealing.Be provided with axial guide between described stationary seal ring 4 and the shell 2.This axial guide is 3 equally distributed guide fingers 6 of circumference.
Described shell 2 is provided with protecting jacket 7, and this protecting jacket 7 is enclosed within the rotating shaft 1, and the gap structure between itself and the rotating shaft 1 is a labyrinth seal structure.
The utility model horizontal concrete mixer comprises shaft sealer, and this shaft sealer is aforementioned novel shaft sealer (figure slightly).
