Description
Technical Field
The utility model belongs to the technical field of sealed fastening, especially, relate to a rotation axis structure that can fasten the packing automatically and seal.
Background
The device used for producing potassium carbonate at present adopts a Swiss Borter fluidized bed process to produce a potassium carbonate product, and a 48 percent potassium hydroxide solution and carbon dioxide gas are adopted to carry out endothermic reaction, so that the produced potassium carbonate material is white granular. In the production process of potassium carbonate, the rotating shaft is an important powder conveying device, and the device is required to convey materials efficiently and continuously. Because the internal pressure is greater than the external air pressure when the rotating shaft is in operation, when the rotating packing seal is worn, the material inside the rotating shaft leaks. When the material temperature is as high as 260 ℃, potential safety hazards and environmental pollution are brought. Therefore, the rotating shaft sealing condition of the rotating shaft plays an important role in safe and efficient operation of the rotating shaft.
The mode fastening of gland is screwed up in advance to the main nut of conventional equipment is sealed, can produce the gap when the packing wearing and tearing, leads to the material to leak, needs the manual work of stopping to twist to sticiss to cover the bolt and prevent to rotate sealed hourglass material. The material leaks not only can cause environmental pollution, still can be because of leaking the material frequently, the fastening space is narrow and small aggravates artifical intensity of labour, and the material temperature is high and equipment fastening has safety risks such as high temperature scald and mechanical injury under running state. Therefore, in order to ensure long-term, stable and safe operation of the rotating shaft, the rotary seal automatic fastening device is necessary.
SUMMERY OF THE UTILITY MODEL
For solving the problem that exists among the prior art, the utility model provides a but automatic fastening packing seal's rotation axis structure, the device realize the effect of automatic fastening through setting up the spring that cup joints in the gland outside and compression bolt, after the packing wearing and tearing, reach and prevent to appear leaking the material pollution, reduce hand labor's effect.
For realizing the purpose of the utility model, the utility model adopts the following technical scheme: a rotating shaft structure capable of automatically fastening a packing seal, comprising: the rotary shaft is arranged in the machine body; the middle position between the inner side of the opening end of the machine body and the outer side of the rotating shaft is provided with a filler; the two sides of the outer side of the opening end of the machine body are respectively provided with a pressing bolt; one end of each compression bolt is sleeved with a packing gland; the longitudinal section of the packing gland is L-shaped, and the horizontal end of the L-shaped gland is inserted into the opening end of the machine body; one end of each compression bolt penetrates through the L-shaped vertical end of the packing gland and is sleeved with the spring; each spring is fixed at the L-shaped vertical end of the packing gland through a cap-shaped nut.
Furthermore, the number of the compression bolts is two or four.
Furthermore, a gasket is arranged between each spring and the cover-type nut.
Further, the filler material is an oil-immersed asbestos rope.
Compared with the prior art, the utility model, following beneficial effect has:
the utility model provides a rotation axis packing seals fastener compresses tightly the rotary seal packing through gland, and along with the change of packing degree of wear, spring length on the spring bolt tends to lengthen, constantly compresses tightly the gland, and rotary seal realizes automatic fastening, and whole equipment is simple, and is with low costs, can show extension maintenance cycle. The device can realize the automatic fastening effect of most rotary seals, avoids causing the polluted environment because of material leakage, reduces the potential safety hazard when the material leaks, has guaranteed rotary seal's safe handling and life.
