Background technology
Banbury is a kind ofly provided with a pair given shape and relatively pivotal rotor, plasticates to polymeric material and mixing machinery, primarily of the part composition such as banburying chamber, rotor, hermetically-sealed construction, reinforced material pressing device, device for discharging, transmission device to intermittence under the air-tight state of adjustable temperature and pressure.
Existing hermetically-sealed construction forms primarily of copper sheathing, and as shown in Figure 4, when material is stirred in axle rotation, copper sheathing 2 plays the effect of body-sealing, prevents liquid material in whipping process from flowing out from internal body.There is following shortcoming in this single copper sheathing hermetically-sealed construction: first: because copper sheathing and main shaft are metal rigidity material, being necessary for matched in clearance, preventing locking when connecting; And because of the limitation of assembly space, copper sheathing is installed must adopt semi-circular partial installation, and the connection contact surface of two semicircle copper sheathings is planes, and after installing, contact surface certainly will exist gap, exacerbates the outflow of liquid material.Second, there is vibration during equipment runs, the gap of axle and copper sheathing is less, and axle is kept away unavoidably in rotation and copper sheathing rubs, thus copper sheathing serious wear, cause gap to strengthen, liquid material runs off serious, contaminated environment and equipment, and significant loss, the hydraulic performance decline of product, according to experience, copper sheathing must be changed when making equipment continuous operation 1 month; Also there is certain wear phenomenon to axle in friction for a long time simultaneously, and the mechanical performance of main shaft is reduced, and repairs difficulty, cause the larger waste of man power and material.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of compound sealing structure closed circuit for the movable sealing of banbury contact, improves sealing property, prevents the outflow of liquid material, reduce the friction of seal and axle, improve service life.
The compound sealing structure closed circuit for the movable sealing of banbury contact described in the utility model, comprise banbury body, banbury body is provided with axle, one end of axle connects the stirrer paddle being positioned at banbury internal body, the other end connects the motor gearbox being positioned at banbury engine body exterior, the junction of axle and banbury body is by being sleeved on the copper sheathing sealing on axle, copper sheathing side is provided with the briquetting for compressing copper sheathing, briquetting is provided with adjustment bolt, on adjustment bolt, cover has spring, briquetting and adjustment bolt are positioned at banbury engine body exterior, copper sheathing opposite side is provided with withstand voltage, heatproof, anti abrasive elastic seal ring, sealing ring is docked by two semicircle sealing rings and forms, the two ends of two semicircle sealing rings are provided with groove and projection, two semicircle sealing rings complete docking by the projection at two ends and groove corresponding matching.
Sealing ring and copper sheathing form compound sealing structure, and sealing ring heatproof is withstand voltage, wear-resistant, there are certain elasticity and ductility, during Relative friction, wearing and tearing can not be caused to axle, when sealing ring causes certain wearing and tearing, can adjusting nut Compress Spring be passed through, extend sealing life; Copper sheathing serves the effect of press seal circle in a device, serves the effect of auxiliary seal simultaneously; This compound sealing structure cost performance is high, convenient maintenance and replacement.Sealing ring adopts lenticular Butt sealing, joint gapless, and sealing effectiveness is better than plane docking mode.
Preferably, withstand voltage, heatproof, anti abrasive elastic seal ring are made up of polytetrafluoroethylene (PTFE), and polytetrafluoroethylene (PTFE) has the advantages such as heatproof, anti-corrosion wear, high lubrication, is the existing most optimum materials meeting this compound sealing structure.
Preferably, the groove of semicircle sealing ring is U-type groove, can form seamless docking, improves sealing, and can add a small amount of lubricating oil in U-type groove, reduces the friction of contact surface.
Preferably, the thickness of sealing ring is 30mm, meets the technical requirement of assembling, sealing.
The beneficial effect that the utility model is compared with prior art had is:
The compound sealing structure closed circuit for the movable sealing of banbury contact is reasonable in design, the compound sealing structure of copper sheathing and elastic seal ring greatly improves sealing property, prevents the outflow of liquid material, reduces the friction of seal and axle, improve service life, use manpower and material resources sparingly.
