The technical solutions in the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the application discloses novel combined type powder concentrator vertical shaft sealing device. Referring to fig. 1, a novel vertical shaft sealing device of a combined powder concentrator comprises a sealing seat body 1 and a transmission vertical shaft 2 rotatably arranged on the sealing seat body 1. Wherein, the both sides of sealed pedestal 1 are seted up the via hole that supplies the bolt to pass for sealed pedestal 1 can be through bolt fixed connection on the selection powder machine. The sealing seat body 1 is provided with a through hole for the transmission vertical shaft 2 to pass through, so that the transmission vertical shaft 2 and the sealing seat body 1 can rotate relatively. A lower containing groove 13 communicated with the through hole is arranged on the sealing seat body 1, and a lower sealing ring 31 is embedded in the lower containing groove 13. Meanwhile, the lower sealing ring 31 is sleeved on the transmission vertical shaft 2 and tightly attached to the surface of the transmission vertical shaft 2, so that the sealing effect is achieved, and external material particles are prevented from entering the sealing seat body 1.
Referring to fig. 1, a sealing ring 4 is fixedly arranged on a transmission vertical shaft 2 below a sealing seat body 1. It should be noted that, in this embodiment, the transmission vertical shaft 2 and the sealing ring 4 are in interference fit, and the assembly is in a hot-pack manner, that is, the sealing ring 4 is heated properly to expand the sealing ring 4, and then the transmission vertical shaft 2 is installed therein, and when the temperature is reduced to the normal temperature, the transmission vertical shaft 2 and the sealing ring 4 are tightly attached to each other.
Referring to fig. 1, a sealing groove 11 is formed on one side of the sealing seat body 1 close to the sealing ring 4, and the sealing groove 11 is formed along the circumferential direction of the sealing seat body 1. A sealing block 41 matched with the sealing groove 11 is integrally formed on one side of the sealing ring 4 close to the sealing seat body 1, so that the sealing block 41 can be inserted into the sealing groove 11. At this moment, a bent gap is formed between the sealing block 41 and the sealing groove 11, when external material particles enter the gap, the material particles can settle on the sealing ring 4 under the action of self gravity, and the material particles are not easy to pass through the gap to enter the sealing seat body 1, so that the sealing effect is greatly improved. Under the effect of promoting sealed effect, the material granule is difficult for entering into in the sealed pedestal 1 and causes wearing and tearing to transmission vertical scroll 2, has reduced the maintenance cost, has effectively improved the operating rate of equipment.
Further, referring to fig. 1, in order to improve the sealing effect, an upper receiving groove 14 communicated with the through hole is formed above the lower receiving groove 13 on the sealing seat body 1, and an upper sealing ring 32 is embedded in the upper receiving groove 14. Meanwhile, the upper sealing ring 32 is sleeved on the transmission vertical shaft 2 and tightly attached to the surface of the transmission vertical shaft 2, so that the sealing effect is achieved, and external material particles are prevented from entering the sealing seat body 1.
Further, referring to fig. 1, the lower seal ring 31, the upper seal ring 32 and the vertical transmission shaft 2 together define an annular oil chamber 5, and the oil chamber 5 is filled with lubricating oil.
