Abstract
A rubber initial refining machine mixing chamber shaft sealing device comprises a rotor which is located the mixing chamber, and a shaft on two ends threads through the mixing chamber, a sealing sleeve which is connected with a shell of the mixing chamber, and is sleeved on the outside of a rotor shaft, wherein the outer side of the sealing sleeve is provided with a seal ring which is sleeved on the outside the shaft, the outer side of the seal ring is sleeved with a slide sleeve, the rotor shaft is fixedly connected with a retainer, and a compression spring is arranged between the slide sleeve and the retainer. Reliable sealing is formed by applying pressure of the compression spring to press the gap between the seal ring and the seal shaft and the sealing sleeve, although the seal ring and the sealing sleeve abrade when relatively rotating, compact seal can be guaranteed by the pressure of the compression spring after abrasion, guaranteeing sealing effect, and the seal ring does not need to be exchanged when abrading, which improves the working efficiency, and reduces the trouble of frequent changing the seal ring.
Description
Technical field:
Shaft sealing device of kneading chamber of rubber kneading machine is the hermetically-sealed construction between the housing axle sleeve of a kind of armature spindle of kneading chamber of rubber kneading machine and mixing chamber, mainly is by tight contact of dynamic extruding sealing ring and cover and axle, realizes sealing.
Background technology:
Existing shaft sealing device of kneading chamber of rubber kneading machine, it all is the sealing that has between the housing axle sleeve of armature spindle and mixing chamber, so all have the axle that is positioned at mixing chamber and two ends to pass the rotor of mixing chamber, be connected with mixing chamber housing and be enclosed within armature spindle sealing shroud outward.In order to guarantee the sealing of sealing shroud and armature spindle, at the sealing shroud inner ring surface annular groove of scrounging, be inlaid with sealing ring in the annular groove, sealing ring is squeezed in the armature spindle cylindrical, realizes sealing.Yet sealing ring is wanted to rotate relative to armature spindle, must cause wearing and tearing, reduces sealing effectiveness, causes leaking; And it is very frequent to change sealing ring, changes very bothersome.
Summary of the invention:
The present invention is exactly the sealing of solution kneading chamber of rubber kneading machine to sealing shroud and armature spindle, uses the problem of back wearing and tearing reduction sealing effectiveness and leakage, and the shaft sealing device of kneading chamber of rubber kneading machine of a kind of compensate for wear in time, assurance sealing effectiveness is provided.
In order to address the above problem, shaft sealing device of kneading chamber of rubber kneading machine of the present invention, there is the axle that is positioned at mixing chamber and two ends to pass the rotor of mixing chamber, be connected with mixing chamber housing and be enclosed within the outer sealing shroud of armature spindle, it is characterized in that: the sealing shroud outside is enclosed within the outer sealing ring of axle in addition, the sealing ring outside is with sliding sleeve, and armature spindle also has fixedly connected back-up ring, between sliding sleeve and the back-up ring compression spring is arranged.The pressure extrusion seal ring seal axle of depended on pressure spring and the gap between the sealing shroud like this, form sealing reliably, though sealing ring will rotate wearing and tearing relative to sealing shroud simultaneously, but the pressure of energy depended on pressure spring keeps sealing closely after the wearing and tearing, guarantee sealing effectiveness, and need not improve operating efficiency once there being wearing and tearing to change sealing ring, reduced the trouble of frequent replacing sealing ring.
In order to reduce the wearing and tearing of sealing ring, prevent the wearing and tearing of sealing shroud simultaneously, the place, angle of ring has breach in the sealing shroud outside, forms ring and lacks; Just have ring lacks in the sealing shroud position corresponding with sealing ring.Ring is scarce to be provided with alloy hoop, and the alloy hoop side contacts sealing with sealing ring.Sealing ring is in the course of work like this, and alloy hoop and the axle higher with hardness form wiper seal, more can guarantee sealing, and main is to relatively rotate friction with the higher alloy hoop of hardness, can reduce the sealing ring friction loss.In order to guarantee the functional reliability of compression spring, guarantee pressure equally, be provided with spring capping between compression spring and the back-up ring, back-up ring is equipped with the adjustment bolt corresponding with spring capping, can adjust the pressure of spring at any time.For the reliability that guarantees to adjust and stable working, the reliability of spring, spring capping is a ring-type, and the position corresponding with compression spring, ring-type side has recessed, recessed and the socket of compression spring end; The alignment pin socket of compression spring and sliding sleeve.In order to guarantee that alloy hoop contacts with the tight of sealing shroud, the alloy hoop outside has gland, and gland is fixedlyed connected with sealing shroud and housing by screw.
Description of drawings:
Accompanying drawing has been represented a kind of structural representation of the present invention, further specifies below in conjunction with the example of accompanying drawing.
Specific embodiment:
This shaft sealing device of kneading chamber of rubber kneading machine of the present invention, have and be positioned at the rotor 34 that mixing chamber and two end axles are passed mixing chamber, be connected with mixing chamber housing and be enclosed within the outer sealing shroud 35 of armature spindle 46, the sealing shroud outside is enclosed within the outer sealing ring 38 of axle in addition, sealing ring is the sealing ring 38 of square-section, the sealing ring outside is with sliding sleeve 40, and armature spindle 46 also has fixedly connected back-up ring 45, between sliding sleeve 41 and the back-up ring 45 compression spring 43 is arranged.The place, angle of ring has breach in the sealing shroud outside, forms ring and lacks; Have ring like this in sealing shroud 35 position corresponding with sealing ring and lack, ring is scarce to be provided with alloy hoop 36, and the alloy hoop side contacts sealing with sealing ring.The alloy hoop outside has gland 37, and gland is fixedlyed connected with sealing shroud and housing by screw.The pressure extrusion seal ring seal of depended on pressure spring the gap between axle and the alloy hoop of sealing shroud like this, forms very reliably to seal.Sealing ring will rotate wearing and tearing relative to the alloy hoop of sealing shroud, but wearing and tearing are very little, and the pressure of energy depended on pressure spring keeps sealing closely after the wearing and tearing, guarantees sealing effectiveness.Sealing ring is the square-section, wear and tear just to change sealing ring for a long time, and the cycle of changing sealing ring is existing more than 100 times of hermetically-sealed construction, has improved operating efficiency, has reduced the trouble of frequent replacing sealing ring.Be provided with spring capping 44 between compression spring and the back-up ring.Spring capping is a ring-type, and the position corresponding with compression spring, ring-type side has recessed, recessed and compression spring end socket; Alignment pin 42 sockets of compression spring and sliding sleeve.Back-up ring is equipped with the adjustment bolt corresponding with spring capping, can adjust the pressure of spring at any time, guarantees the functional reliability of compression spring, guarantees pressure.For the ease of the assembling and the adjustment of sliding sleeve, sliding sleeve is the flap of butt joint, and each lobe 39 connects into ring-type by bolt.Sliding sleeve has the key of distribution, and key has bayonet socket, and bayonet socket is stuck on the becket, and the becket and the sealing ring outside are enclosed within outside the axle side by side, and parallel crush seal ring closely contacts sealing with alloy hoop and axle, has formed more reliable hermetically-sealed construction.
