Description
Technical field
Bulking machine technical field is the utility model is related to, more particularly to one kind is applied in aquatic products expanded pellet feed density control
Impeller axle sealing structure on control equipment.
Background technology
Development and the domestic raising to cultivation water environment standard with aquaculture, country are arranged cultivation from legal perspective
The supervision of water is strengthened, and raiser switchs to feed expanded heavy property material from the heavy property material of granulation before.Expanded sinking feed curing degree is good,
Water stability is good, puts into water and is not easy to scatter, and pulverization rate is low, the good absorbing of fish, and excretion is clean, and the pollution to water is lacked, but
The light unit weight of puffing material density is low, easily swims, inconvenient for operation.In this case, it is badly in need of research and development and coordinates the close of bulking machine
Degree control device solves the problems, such as to do jetsam with bulking machine difficulty.And existing impeller spindle sealing effectiveness is poor, is needed after spindle abrasion
Want integral replacing impeller, cost height.
Utility model content
The purpose of this utility model is to solve existing aquatic products expanded pellet feed density control equipment impeller sealing
The problems such as structure, sealing effectiveness is poor, and main shaft is easy to wear, and replacement cost is high, and spindle abrasion can effectively be prevented by providing one kind, it is close
It is good to seal effect, it is convenient to change, the low impeller axle sealing structure of cost.
Technical scheme is used by the utility model realizes its technical purpose：A kind of impeller axle sealing structure, including：
Impeller and impeller spindle, shaft seal assembly are provided with the impeller spindle at described impeller both ends, described axle is close
Sealing assembly includes oil sealing anti-wearing liner, O-ring seals and oil sealing；Described O-ring seals are arranged on impeller spindle, described
Oil sealing anti-wearing liner is arranged on impeller spindle and is pressed on O-ring seals, and described oil sealing is arranged on oil sealing wear-resisting lining
Cover on excircle.
The impeller axle sealing structure, by carrying out brand-new design to axle sealing structure, O-ring seals are set on main shaft,
An oil sealing anti-wearing liner is arranged on O-ring seals, then oil sealing, in use, leaf are set on oil sealing anti-wearing liner
Main shaft is taken turns in operation process, due to being provided with oil sealing anti-wearing liner, Neng Goubao on impeller spindle when the oil sealing of outer layer is worn
Main shaft will not be hurt during card oil sealing abrasion, meanwhile, O-ring seals are set between oil sealing anti-wearing liner and impeller spindle, it is inside and outside
Two layers of sealing structure, it ensure that the sealing gland of equipment.The impeller axle sealing structure, it can effectively prevent spindle abrasion, sealing effect
Fruit is good, and it is convenient to change, and cost is low.
Preferably, fluted, described O-ring seals are set to be arranged on inside grooves on described impeller spindle.If
The setting that groove facilitates O-ring seals is put, while sealing effectiveness can be ensured.
Preferably, described oil sealing anti-wearing liner abuts close to one end of impeller with impeller end face.Oil sealing anti-wearing liner
Abutted close to one end of impeller with impeller end face, can so ensure sealing effectiveness.
Preferably, described oil sealing is at least provided with two layers.The quantity of oil sealing can be configured as needed, as long as
Sealing effectiveness can be ensured.
Preferably, described impeller and impeller spindle split settings；Described impeller is socketed on impeller spindle.By leaf
Take turns main shaft to design with impeller split, such design structure overcomes the defects of existing impeller is with impeller spindle Integral design, makes
Obtain impeller body and made with main shaft and more facilitated, and such structure can be individually replaced impeller when impeller spindle need to be changed
Main shaft, and without changing whole impeller, both facilitated operation, while also reduce maintenance cost.
The beneficial effects of the utility model are：The impeller axle sealing structure, is disposed with O shapes from inside to outside on main shaft
Sealing ring, oil sealing anti-wearing liner, oil sealing, impeller spindle in operation process, can ensure oil sealing abrasion when will not hurt main shaft,
The sealing gland of equipment is ensure that simultaneously.The impeller axle sealing structure, spindle abrasion can be effectively prevented, good sealing effect, is changed
Convenient, cost is low.
