Abstract
The utility model relates to a sealing structure on the end part of a shaft for powder equipment, which comprises a main body (6) of the equipment, a rotary shaft (8), a pressing cover (2), a bearing (11) which is used for supporting the rotary shaft (8), and a bearing seat (1), wherein the press cover pressing cover (2) is sheathed on the rotary shaft (8) and is fixedly connected with the main body (6) of the equipment, a filler (4) is arranged on a gap point between the main body (6) of the equipment and the rotary shaft (8), and the right end surface of the pressing cover (2) is contacted with the filler (4). The utility model is characterized in that an air distributing ring (7) is arranged on the middle of the filler (4), and a through hole (9) is arranged on the main body (6) of the equipment corresponding to the air distributing ring (7); an air inlet connector (5) which is connected with an air source is installed in the through hole (9), and the air inlet connector (5) is communicated with the air distributing ring (7). Because the function of the air flow, the powder can not enter the gap between the filler and the rotary shaft by using the utility model; the utility model also has the advantages of good sealing performance, no material leakage and less abrasion of the surface of the rotary shaft; the serviceability rate of the equipment is improved, and the maintenance cost of the equipment is reduced.
Description
Technical field
The utility model relates to a kind of axle sealing structure, specifically, relates to a kind of powder equipment axis end seal structure.
Background technique
Powder conveying equipment of the prior art and powder flow through the shaft end of equipment, generally bearing and bearing support are arranged in the outside of equipment body, the gap location of the equipment that also has between rotatingshaft and equipment body is provided with filler, and gland and hold down gag etc. do not leak material with the gap location that guarantees the equipment rotatingshaft, but sealability is bad, the material of leakage phenomenon is still arranged, cause dust pollution, influence surrounding enviroment, and cause the rotatingshaft surface abrasion, cause the maintenance expenses of equipment to increase.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good seal performance is provided, the powder equipment axis end seal structure that the rotatingshaft surface abrasion is few.
The technological scheme that realizes above-mentioned purpose is: a kind of powder equipment axis end seal structure, the bearing and the bearing support that comprise equipment body, rotatingshaft, gland and supporting rotatingshaft, gland is enclosed within on the rotatingshaft and is fixedly connected in equipment body, gap location between equipment body and the rotatingshaft is provided with filler, the right side of gland is against on the filler, be provided with the cloth compression ring in the middle of the filler, and the position of corresponding cloth compression ring has through hole on equipment body, the air input joint that is connected with source of the gas is installed in the through hole, and air input joint communicates with the cloth compression ring.
After adopting technique scheme, be provided with the cloth compression ring in the middle of the filler, and the position of corresponding cloth compression ring has through hole on equipment body, and the air input joint that is connected with source of the gas is installed in the through hole, and air input joint communicates with the cloth compression ring.Thereby can from air input joint, feed the pressurized air of suitable pressure; the pressure of powder is slightly high in the pressure ratio equipment; by the cloth compression ring; the gas of certain pressure is arranged all the time around filler at the stuffing box place of rotatingshaft; gap between filler and the rotatingshaft is because the effect of air-flow; make powder can not creep into gap between filler and the rotatingshaft; guarantee the sealability of powder equipment; and prevented to leak the material phenomenon; avoided dust pollution to reduce the wearing and tearing on rotatingshaft surface simultaneously; improved the serviceability rate of equipment, reduced the maintenance expenses of equipment, to the environmental protection and the important meaning that economizes in raw materials.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, a kind of powder equipment axis end seal structure, the bearing 11 and the bearing support 1 that comprise equipment body 6, rotatingshaft 8, gland 2 and supporting rotatingshaft 8, gland 2 is enclosed within on the rotatingshaft 8 and is fixedly connected in equipment body 6, gap location between equipment body 6 and the rotatingshaft 8 is provided with filler 4, the right side of gland 2 is against on the filler 4, be provided with cloth compression ring 7 in the middle of the filler 4, and the position of corresponding cloth compression ring 7 has through hole 9 on equipment body 6, the air input joint 5 that is connected with source of the gas is installed in the through hole 9, and air input joint 5 communicates with cloth compression ring 7.
As shown in Figure 1, gland 2 is fixedlyed connected with equipment body 6 with nut 3 by compressing double-screw bolt 10, screws nut 3 and just can make gland 2 compress filler 4, further improves the sealability of shaft end.
Working principle of the present utility model is as follows:
During work, feed the pressurized air of suitable pressure from air input joint 5, the pressure of powder is slightly high in the pressure ratio equipment, and by cloth compression ring 7, the gas that certain pressure is arranged at the stuffing box place of rotatingshaft 8 is all the time around filler 4.
When rotatingshaft 8 transfixions, have a spot of air from stuffing box diffluence in equipment, because amount seldom, blow the powder in the motionless equipment, big influence can not arranged to the powder in the equipment, but the gap between filler 4 and the rotatingshaft 8 is because the effect of air-flow, makes powder can not creep into gap between filler 4 and the rotatingshaft 8.
When rotatingshaft 8 rotates, having air in certain amount equally flows to the equipment the inside from stuffing box, because amount is few, be not enough to blow the powder in the equipment and refluence or other action occur, can not influence the equipment proper functioning, but the gap between filler 4 and the rotatingshaft 8 is because the effect of air-flow, makes powder can not creep into gap between filler 4 and the rotatingshaft 8.
Certainly no matter rotatingshaft 8 static or rotations have the gap of air between filler 4 and rotatingshaft 8 and flow to gland 2 directions from stuffing box, and finally enter atmosphere,, can not influence the proper functioning of entire equipment because tolerance is few.
In a word, need only when in the equipment body 6 powder being arranged, the air of suitable pressure just can be provided from air input joint 5, can not enter the gap between filler and the axle, reach the purpose that prevents the powder leakage, prevents the rotatingshaft surface abrasion to guarantee powder.
Claims (2)
1, a kind of powder equipment axis end seal structure, comprise equipment body (6), rotatingshaft (8), the bearing (11) and the bearing support (1) of gland (2) and supporting rotatingshaft (8), it is last and fixedly connected in equipment body (6) that gland (2) is enclosed within rotatingshaft (8), gap location between equipment body (6) and the rotatingshaft (8) is provided with filler (4), the right side of gland (2) is against on the filler (4), it is characterized in that: be provided with cloth compression ring (7) in the middle of the filler (4), and the position of corresponding cloth compression ring (7) has through hole (9) on equipment body (6), the air input joint (5) that is connected with source of the gas is installed in the through hole (9), and air input joint (5) communicates with cloth compression ring (7).
