Abstract
The utility model discloses a main shaft sealing structure of a plastic high-speed mixing machine. The main shaft sealing structure of the plastic high-speed mixing machine comprises a main shaft, a shaft sleeve and a sealing seat, wherein the shaft sleeve is arranged on the main shaft in a sleeved mode and rotates along with the main shaft, and the sealing seat is fixed to a boiler body of the mixing machine. The main shaft sealing structure of the plastic high-speed mixing machine is characterized in that three framework seals are arranged between the shaft sleeve and the sealing seat in the vertical direction, a separation ring is arranged between the two frameworks seals below, the upper end of the framework seal on the uppermost portion is connected with a sealing plate, the upper end of the sealing plate is connected with a sealing cover, and the interval between the sealing plate and the sealing cover forms a labyrinth seal. The main shaft sealing structure of the plastic high-speed mixing machine can effectively prevent powdery materials from entering the mains shaft, is long in service life and is high reliability.
Description
Technical field
The utility model belongs to technical field of plastic, has especially related to a kind of sealing configuration of plastic high-speed mixer main shaft.
Background technique
High-speed mixer is the plastics mixing apparatus generally using at present, and the reliability of main shaft seal wherein has directly affected the reliability that mixing machine uses.If it is unreliable to seal, the powder in mixing machine will enter bearing, thereby makes main shaft and the too early wearing and tearing of bearing.The main shaft seal of existing high-speed mixer has following two kinds of modes:
(1) teflin ring+outside framework oil seal
(2) packing seal+air-purge seal
Above-mentioned these two kinds of sealing means all cannot prevent that the powder of mixing machine from entering in sealing configuration, thereby cause the wearing and tearing of main shaft and bearing.First kind of way outside framework oil seal can damage very soon, and second way gland sealed lubricating grease is easy to enter in mixing machine, contaminated material.Thus, be badly in need of a kind of good main shaft sealing construction, to solve the bad problem of mixing machine main shaft reliability.
Model utility content
The purpose of this utility model is to provide a kind of for generally using at present the improvement at the high-speed mixer main shaft sealing construction of plastic processing industry, be used for solving current mixing machine main shaft seal reliable sealing for a long time, leak and expect and cause bearing wear, bearing grease to enter to cause in mixing machine the problems such as material is contaminated.
For realizing above-mentioned model utility object, the utility model has adopted following technological scheme:
A kind of plastic high-speed mixer main shaft sealing construction, comprise main shaft, axle sleeve and sealing seat, described axle sleeve is enclosed within on main shaft and rotates with main shaft, described sealing seat is fixed on the pot body of mixing machine, it is characterized in that, between described axle sleeve and sealing seat, arrange and be provided with three reinforced seals by Vertical direction, wherein between two reinforced seals in below, be provided with spacer ring, a reinforced seal upper end of the top is connected with seal disc, described seal disc upper end is connected with sealing cover, and the space between described seal disc and sealing cover forms labyrinth sealing.
Described labyrinth sealing refers to that the space of seal disc and sealing cover moves towards more complicated, as sawtooth, to increase dielectric leakage path and dielectric leakage frictional force, thereby reduces relative permitivity.
As one of preferred version, below described main shaft both sides, sealing seat, be provided with two compressed air inlets, in sealing seat, arrange porosely as air passageways, described air passageways two ends connect respectively described compressed air inlet and described labyrinth sealing.Pressurized air from enter opening's edge air passageways by sealing seat and seal disc, enter labyrinth sealing and be evenly distributed on space, can stop that thus in pot body, dust enters main shaft from space.
As one of preferred version, below described main shaft both sides, sealing seat, be provided with a lubricating oil inlet and lubricating oil outlet, this lubricating oil inlet is connected with lubricating oil outlet by the asphalt channel being arranged in sealing configuration, and described asphalt channel is by described sealing seat, spacer ring and reinforced seal.Lubricant oil enters reinforced seal along asphalt channel it is lubricated, and makes outside framework oil seal be not easy wearing and tearing, increases the service life.
The main purpose of outside framework oil seal is to prevent pressurized air refluence instead of the sealing for main shaft.Only have pressurized air to enter uniformly in mixing machine along air passageways, could stop powder to enter main shaft.
Model utility advantage:
Plastic high-speed mixer main shaft sealing construction described in the utility model is compared with traditional main shaft sealing construction, and tool has the following advantages:
1. compressed-air actuatedly continue to pass into effective prevention powder and enter main shaft from space.
2. arranging of reinforced seal further prevented pressurized air refluence, makes to stop that the effect of powder is better
3. passing into of lubricant oil extends reinforced seal working life, makes the reliability of whole sealing configuration better.
Brief description of the drawings
Fig. 1 is the cross-sectional view that sealing configuration described in the utility model has compressed air channel;
Fig. 2 is the cross-sectional view that sealing configuration described in the utility model has grease channel.
Wherein, 1, main shaft, 2, axle sleeve, 3, sealing seat, 4, reinforced seal, 5, spacer ring, 6, seal disc, 7, sealing cover, 8, labyrinth sealing, 9, compressed air inlet, 10, air passageways, 11, lubricating oil inlet, 12, lubricating oil outlet, 13, asphalt channel.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the technical solution of the utility model is further described.
A kind of plastic high-speed mixer main shaft sealing construction, comprise main shaft 1, axle sleeve 2 and sealing seat 3, described axle sleeve 2 is enclosed within on main shaft 1 with main shaft 1 rotation, described sealing seat 3 is fixed on the pot body of mixing machine, between described axle sleeve 2 and sealing seat 3, arrange and be provided with three reinforced seals 4 by Vertical direction, wherein between two reinforced seals 4 in below, be provided with spacer ring 5, reinforced seal 4 upper ends of the top are connected with seal disc 6, described seal disc 6 upper ends are connected with sealing cover 7, and the space between described seal disc 6 and sealing cover 7 forms labyrinth sealing 8.
