Problems solved by technology

A lot of waste rubber is regenerated after being plasticized by the plasticizing device. The temperature of the plasticizing device is high during operation, which makes the sealing effect of the output shaft of the plasticizing device's drive shaft poor, which leads to the leakage of dust in the plasticizing device and pollution. surroundings

Embodiment Construction

[0011] The present invention will now be further described with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0012] like figure 1 The shown shaft end gas sealing device includes a sealing seat 2 fixed on the plasticizing device 1, and a transmission shaft 3 is passed through the sealing seat 2, and the driving shaft 3 rotates through the bearing seat fixed on the plasticizing device 1. Support, the sealing seat 2 is provided with a stepped hole through which the transmission shaft 3 is inserted. The stepped hole includes a small hole, a middle hole and a large hole arranged from the inside to the outside in sequence, and two annular grooves 4 are arranged on the inner wall of the small hole. A skeleton oil seal assembly is arranged between the large hole and the transmissio...

Abstract

The invention discloses a shaft end gas sealing device. The shaft end gas sealing device comprises a sealing base fixed on a plastifying device, wherein a transmission shaft is inserted in the sealing base, and is rotationally supported through a bearing base fixed on the plastifying device; step holes for inserting through the transmission shaft are formed in the sealing base, and consist of a small hole, a middle hole and a large hole arranged from inside to outside in sequence; two annular grooves are formed in the inner wall of the small hole; a skeleton oil seal component consisting of at least one skeleton oil seal is arranged between the large hole and the transmission shaft; and an annular space between the middle hole and the transmission shaft is communicated with the external through an air inlet way and an air outlet way arranged in the sealing base. The two annular grooves formed in the inner wall of the small hole have an effect of dust accumulation; along with the increment of the dust accumulation, larger dust particles in the plastifying device can be stopped from entering the middle hole from the small hole; and the dust entering the middle hole can be brought outside the sealing base for separate treatment through gas sealing, so that the problem of environment pollution caused by the dust leakage of the plastifying device is effectively solved.

Description

technical field [0001] The invention relates to a shaft end gas sealing device. Background technique [0002] my country is the world's largest rubber consuming country, but domestic rubber resources are very scarce. More than 70% of natural rubber is imported. The recycling of waste rubber is of great significance to fill the lack of rubber resources. Many waste rubbers are regenerated after being plasticized by the plasticizing device. The temperature of the plasticizing device is high during operation, which makes the sealing effect of the drive shaft of the plasticizing device poor, resulting in the leakage of dust in the plasticizing device and pollution. surroundings. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, and to provide a shaft end gas sealing device that prevents the dust in the plasticizing device from leaking out and polluting the environment. [0004] The t...
