Abstract
The invention discloses a high-temperature-resistant embedded roller shaft sealing device. The device comprises an air chamber, an embedded sealing box, a sealing filler and a sealing pressing plate, wherein shaft holes matched with a roller shaft are formed on the inner end face and outer end face of the embedded sealing box; a plurality of air holes are uniformly distributed on the side face of the embedded sealing box; a sealing convex ring matched with the sealing pressing plate is arranged around the shaft holes on the outer end face of the embedded sealing box; the sealing filler is arranged in the sealing convex ring; a pressing plate shaft hole matched with the roller shaft is formed in the center of the sealing pressing plate; the sealing pressing plate is sleeved in the sealing convex ring and presses the sealing filler; the embedded sealing box is arranged in the air chamber in an embedded mode and passes through the air chamber; the air holes on the embedded sealing box are positioned in the air chamber; a cooling air pipe is arranged on the outer end face of the air chamber; and after high-speed air flow which enters the air chamber is mixed in the air chamber, a high-speed air flow isolating layer is formed under the guidance of the embedded sealing box, so that the sealing filler is isolated from high temperature, the working environment of the sealing filler is improved, and the sealing effect is improved.
Description
Technical field
The present invention relates to a kind of high-temperature-resistant embedded roller shaft sealing device, relate in particular to a kind of embedded high-temperature sealing device that is applicable to the grog kibbler roll.
Background technology
For the equipment that is operated under hot environment, grog kibbler roll for example especially is positioned at the kibbler roll in grate-cooler stage casing, and its target is hot high temperature chamotte, and temperature even can reach more than 900 ℃, and working environment is very abominable.The Seal Design of the disintegrating machine roll shaft being passed the housing place is serious test.Traditional contact seal is not suitable for herein because of the airtight and watertight padding that can bear high temperature like this that is not fit to; And its too tortuous trickle structural design of non-contacting seal (as labyrinth seal) easily produces distortion at so high temperature and can't guarantee to realize the sealing effectiveness of its expection.For the sealing that realizes that under this kind operating mode, equipment is association of activity and inertia and is located, certainly can realize by seeking the airtight and watertight padding that to bear high temperature, but this often requires a great deal of time and energy, if can be by structural reasonable Arrangement, reduce the temperature of sealing place, improve sealed environment, herein a sealing difficult problem just is readily solved.
Summary of the invention
For above-mentioned situation, the present invention proposes a kind of high-temperature-resistant embedded roller shaft sealing device, by introducing high speed cooling blast isolating seal filler and hot environment, improved the working environment of airtight and watertight padding, greatly improve the life-span of airtight and watertight padding, improved sealing property.
For achieving the above object, the present invention has adopted following technical scheme: a kind of high-temperature-resistant embedded roller shaft sealing device comprises the air compartment, embedded seal box, airtight and watertight padding, the sealing clamp that are arranged on the apparatus casing that roll shaft passes.
The cavity structure of described embedded seal box for being consisted of by inner face (end face that is installed on apparatus casing inside is inner face), outer face and side, the inner face of embedded seal box and outer face are equipped with the axis hole adaptive with roll shaft, the side of embedded seal box evenly is distributed with some pores, be provided with the sealing bulge loop adaptive with sealing clamp around axis hole on the outer face of embedded seal box, airtight and watertight padding is placed in the sealing bulge loop.The sealing clamp center is provided with the pressing plate axis hole adaptive with roll shaft, and sealing clamp is set in the sealing bulge loop, and airtight and watertight padding is compressed.
Described air compartment is the double-layer seal structure, and embedded seal box is embedded to be installed in air compartment and to connect air compartment, and the some pores on the side of embedded seal box are arranged in air compartment, and the outer face of air compartment is provided with cooling tracheae.
Its groundwork principle is: utilize relatively airtight air compartment, enter the high velocity air of air compartment by cooling tracheae after the air compartment internal mix, form under the guiding of embedded seal box one have certain pressure and stationary flow to high velocity air isolated airtight and watertight padding and high temperature, improved the working environment of airtight and watertight padding, improved the effect of sealing, also be very helpful for the range of choice of expanding airtight and watertight padding.
This high-temperature-resistant embedded roller shaft sealing device, simple in structure, be bolted between each building block, easy for installation, can effectively improve the working environment of airtight and watertight padding, improved sealing effectiveness, improved the service life of airtight and watertight padding.
Description of drawings
Fig. 1 is the cross-sectional view of high-temperature-resistant embedded roller shaft sealing device of the present invention.
Fig. 2 is the schematic perspective view of embedded seal box.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, 2, embedded high-temperature sealing device of the present invention comprises air compartment 1, embedded seal box 2, airtight and watertight padding 3, sealing clamp 4.Air compartment is arranged on apparatus casing and (just is bilayer, the structure of self-assembling formation air compartment as apparatus casing at that face itself that roll shaft passes), is positioned at the position that roll shaft passes.Air compartment is the double-layer seal structure, and the outer face of air compartment is provided with cooling tracheae 9.Embedded seal box 2 embeds in air compartment 1, and embedded seal box runs through air compartment, becomes the part of housing.The cavity structure of embedded seal box for being consisted of by inner face 5, outer face 6 and side 7, the inner face of embedded seal box and outer face are equipped with the axis hole adaptive with roll shaft, the side of embedded seal box evenly is distributed with some pores 8, and the some pores 8 on the side of embedded seal box are arranged in air compartment.Be provided with the sealing bulge loop 10 adaptive with sealing clamp around axis hole on the outer face 6 of embedded seal box, airtight and watertight padding is placed in the sealing bulge loop.The sealing clamp center is provided with the pressing plate axis hole adaptive with roll shaft, and sealing clamp is set in the sealing bulge loop, and airtight and watertight padding is compressed.Roll shaft passes the axis hole on pressing plate axis hole and sealed letter end face, and airtight and watertight padding is with the sealing of the axis hole on roll shaft and sealed letter outer face.
The cavity of embedded seal box 2 is between airtight and watertight padding and hot environment, enter the high speed cooling blast of air compartment 1 after air compartment 1 crosses, form under the guiding of embedded seal box 2 again one have certain pressure and stationary flow to the isolated airtight and watertight padding of high velocity air and hot environment.Embedded seal box 2 can be set up deflector as required, to regulate the flow direction and the time of staying in the cavity of embedded seal box 2 of air-flow, improve isolated effect, create a good working environment to airtight and watertight padding, greatly improve the life-span of airtight and watertight padding, improved sealing property.
