Therefore, PVC (Polyvinyl Chloride) materials in a boiler body of the mixer are prevented from leaking out of the boiler body.
Description
Technical field
The present invention relates to a kind of main shaft sealing device of high-speed mixer.
Background technique
Mixing machine is mainly used to mix the PVC materials such as PVC＝polyvinyl chloride, polyethylene and polypropylene, and mainshaft sealing device of mixing machine then is used for the sealing between mixing machine main shaft and the mixing machine pot body.Mixing machine is thrown in the PVC material of granular in the mixing machine pot body first when mixing the PVC material, rotates by the mixing machine main shaft, drive the blade that is fixed on the mixing machine main shaft and rotate, by blade PVC material stirring, mixing.Axle sleeve and seal ring are adopted in sealing between mixing machine main shaft and the pot body usually, adopt this seal arrangement because sealability is relatively poor, and it is external that the PVC material of part granular can leak into pot by the sealing device.
Therefore, be necessary to provide preferably main shaft sealing device of a kind of sealability.
Summary of the invention
A technical problem to be solved by this invention is: provide a kind of PVC of preventing material to leak into the external main shaft sealing device of pot when mixing.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of main shaft sealing device of high-speed mixer, comprise: main shaft, axle sleeve, skeleton-type oil seal, sealing seat, the sealing seat gland, seal ring, air flue bracing ring and lower oar, described axle sleeve is installed on the main shaft, described skeleton-type oil seal is sheathed on the axle sleeve, described sealing seat gland is installed on an end of sealing seat, fix by the first screw between described sealing seat gland and the sealing seat, fix by the second screw between described air flue bracing ring and the sealing seat, described seal ring is installed between sealing seat and the axle sleeve, offer vent on the described sealing seat, the outside of described sealing seat is provided with the gas-tpe fitting that communicates with vent, be provided with the air cavity that communicates with vent between described air flue bracing ring and the sealing seat, described air flue bracing ring is provided with the passage that communicates with air cavity, be formed with the first gap that communicates with the passage of air flue bracing ring between described air flue bracing ring and the axle sleeve, be provided with spacer between described lower oar and the air flue bracing ring, form the second gap that communicates with the first gap between described spacer and the air flue bracing ring.
Beneficial effect of the present invention: the main shaft sealing device among the present invention is simple in structure, and is easy for installation, owing to be provided with vent and spacer, after passing into source of the gas, can prevent effectively that the PVC material from leakage in the mixing machine pot body from arriving external of pot.
