Abstract
The utility model discloses a seal compensating type air seal machine which comprises an air seal machine body. A feeding opening is formed in the upper end of the air seal machine body, meanwhile, a discharging opening is formed in the lower end of the air seal machine body, a rotating shaft is arranged in the middle of the air seal machine body, the rotating shaft is fixedly arranged on the air seal machine body through bearings, and seal compensating structures are arranged between the rotating shaft and the air seal machine body. Two sets of seal compensating structures are arranged, and are arranged at the positions of the bearings at the two ends of the rotating shaft respectively, and each seal compensating structure is composed of a jackscrew ring, a compression spring, a fixed ring and a sealing ring. According to the seal compensating type air seal machine, the service life of the sealing rings is prolonged, the maintenance frequency of the air seal machine is reduced, use efficiency of the machine is improved, meanwhile, the clean, tidy and healthful production environment can be better maintained, and unnecessary losses of the materials are avoided.
Description
Technical field
The utility model relates to a kind of air sealer, relates to specifically the sealing compensation type air sealer using in a kind of powdery material unloading.
Background technology
Air sealer is the visual plant in strength conveying and dust removal by ventilation network, and its radical function is that the material in discharger or dust exhaustor is continuously discharged in time, stops outer air to enter in discharger or dust exhaustor simultaneously.Air sealer is widely used in the strength transportation of the industry equipment such as husk rice, powder process, feed, machinery and chemical industry, medicine, tobacco, metallurgy, cement and dedusting and the discharging of ductwork pressure state.For in malleation, the powdery under negative pressure state, graininess, sheet and fibre material play a part continuous disposing and close gas.
Existing air sealer can be altered the phenomenon of powder in use for some time, this is because the seal ring between air sealer main body and rotating shaft is worn, cause poorly sealed close, make the gap between rotating shaft and air sealer main body become large, thereby cause powder to be scurried out by gap from air sealer body interior, not only caused the unnecessary waste of material, also destroyed the clean and tidy of production environment, and air sealer integral body need to be removed to change when seal ring is changed, replacing difficulty is lower and efficiency is too low, also greatly reduces the service efficiency of air sealer.
Summary of the invention
In view of this, the utility model provides a kind of sealing compensation type air sealer, the service life of having improved seal ring, reduced the frequency of maintenance of air sealer, improve its service efficiency, also can better safeguard the clean and tidy health of production environment simultaneously, avoided the unnecessary loss of material.
For solving above technical matters, the technical solution of the utility model is:
Sealing compensation type air sealer, comprise air sealer main body, upper end in air sealer main body offers feeding mouth, in the lower end of this air sealer main body, also offer discharging opening simultaneously, the middle part of described air sealer main body is provided with rotating shaft, this rotating shaft is fixed in air sealer main body by bearing, between this rotating shaft and air sealer main body, is also provided with sealing compensation structure.
Further, the quantity of above-mentioned sealing compensation structure is two groups, is separately positioned on the position of bearings place at rotating shaft two ends, and every group of sealing compensation structure is comprised of jackscrew circle, Compress Spring, set collar and seal ring again.
As preferably, described jackscrew circle is arranged on the outside of bearing, and by draw-in groove, is fixed on the inwall of air sealer main body.
As preferably, described Compress Spring is arranged on the inner side of bearing, and the two ends of this Compress Spring are respectively arranged with a set collar.
As preferably, in described every group of sealing compensation structure, be provided with two set collars, one of them set collar contacts with bearing medial surface, and another set collar contacts with the end of seal ring.
In addition, described seal ring is arranged between set collar and rotating shaft, and the section camber of sealing circle.
Compared with prior art, the utility model has following beneficial effect:
The utility model has been used sealing compensation structure, has improved the service life of seal ring, has reduced the frequency of maintenance of air sealer, has improved its service efficiency, also can better safeguard the clean and tidy health of production environment simultaneously, has avoided the unnecessary loss of material; The utility model is provided with jackscrew circle at the lateral surface of bearing, can be good at avoiding bearing to be subjected to displacement after being under pressure, and has better ensured the normal use of equipment; Seal ring of the present utility model is close in rotating shaft under the effect of set collar of receiving Compress Spring extruding always, thereby produce gap in the process of having avoided using at equipment between rotating shaft and air sealer main body, and then time of the normal operation of equipment, service life of having improved equipment have better been ensured; The utility model is simple in structure, easy to use, produces and follows the cost of processing lower, can be good at carrying out large-scale production and use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is part sectional view of the present utility model.
On figure, Reference numeral is: 1-rotating shaft; 2-sealing compensation structure; 3-seal ring; 4-set collar; 5-Compress Spring; 6-bearing; 7-jackscrew circle.
The specific embodiment
Core thinking of the present utility model is to provide a kind of sealing compensation type air sealer, the service life of having improved seal ring, reduced the frequency of maintenance of air sealer, improve its service efficiency, also can better safeguard the clean and tidy health of production environment simultaneously, avoided the unnecessary loss of material.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment
As shown in Figure 1, 2, sealing compensation type air sealer, comprise air sealer main body, upper end in air sealer main body offers feeding mouth, in the lower end of this air sealer main body, also offer discharging opening simultaneously, the middle part of described air sealer main body is provided with rotating shaft 1, and this rotating shaft 1 is fixed in air sealer main body by bearing 6, between this rotating shaft 1 and air sealer main body, is also provided with sealing compensation structure 2.
The quantity of above-mentioned sealing compensation structure 2 is two groups, is separately positioned on bearing 6 positions at rotating shaft 1 two ends, and every group of sealing compensation structure 2 is comprised of jackscrew circle 7, Compress Spring 5, set collar 4 and seal ring 3 again.
