Technical field
The utility model relates to a kind of mixing machine, particularly a kind of new hybrid arbor end sealing mechanism.The utility model belongs to mixing machinery device fabrication processing technique field.
Background technique
Mixing machine is to use a kind of common mixing apparatus that very widely material is mixed at present, is mainly used in fields such as feed, grain, medicine, chemical industry.Mixing machine generally rotates through the main shaft that power drives mixing machine, and the rotation of main shaft drives the blade with stirring action that is arranged on the main shaft or stirring rod etc. and synchronously rotates, thereby makes blade or stirring rod etc. play the effect that mixes to material.Main-axis end is arranged on the mixing machine wallboard in mixing machine; Mechanism seals main-axis end through the mixing machine shaft end seal; Can not scurry out with material in the assurance mixing machine mixed process, so the main-axis end sealing mechanism is the important component part of mixing machine from main-axis end.Existing mixing machine shaft end seal mechanism, referring to Fig. 2, its structure generally comprises sealing seat and the sealing cover that is sleeved on the main shaft, and sealing cover is connected on the side end face of sealing seat, is provided with packing between sealing cover and the sealing seat.Existing mixing machine shaft end seal mechanism also exists following defective: adopt mechanical seal; The weak effect of sealing; The material or the phenomenon of dusting appear leaking in main-axis end, and particularly the leakage material or the phenomenon of dusting are more serious in premix mixed process, and this not only influences mixed effect; But also the pollution working environment, even bring certain potential safety hazard.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of simple in structure, good sealing effect, the reliable new hybrid arbor of sealingly secure end sealing mechanism are provided.
For realizing above-mentioned purpose, the utility model adopts following technological scheme: a kind of new hybrid arbor end sealing mechanism, include the sealing seat and the sealing cover that are sleeved on the main shaft, and sealing cover is connected on the side end face of sealing seat.The utility model also includes wear-resistant sleeve, oil sealing, spacer ring and No. two oil sealings; Have through hole on the described sealing seat; The through hole is provided with intake interface; Sealing cover, an oil sealing and No. two oil-sealing sleeves are contained on the external diameter of wear-resistant sleeve, and the external diameter of an oil sealing and No. two oil sealings is installed in the anterior cavity of sealing seat, between an oil sealing and No. two oil sealings spacer ring are housed.
Further, also include sealing gasket, sealing gasket is arranged on the opposite side end face of sealing seat.
Further, also include lubricating cup, also have the lubricated through hole relative with spacer ring on the described sealing seat, lubricating cup is arranged on lubricated through hole.
Further, the rear portion internal diameter of said sealing seat is provided with internal thread.
Further, described sealing cover is connected on the side end face of sealing seat through screw.
Owing to adopt technique scheme, the utlity model has following beneficial effect:
(1) the utility model is owing to have through hole on the sealing seat, and the through hole is provided with intake interface.This structure makes uses the mixing machine axle head of the utility model to increase the hermetic seal structure, good sealing effect, and sealingly secure is reliable.
(2) the utility model improves the packing seal in original sealing mechanism; Be provided with wear-resistant sleeve, oil sealing, spacer and No. two oil sealings; This structure makes that the mechanical seal that the utlity model has is more reliable, good sealing effect, and sealingly secure is reliable.
(3) increase of sealing gasket makes the utility model sealability strengthen good sealing effect.
The utility model is simple in structure, and the utility model not only has powerful reliable multiple mechanical seal ability, has also increased the hermetic seal ability, has multiple multiple sealing, and the mixing machine axle head can not occur and leak the material or the phenomenon of dusting, good sealing effect, sealingly secure is reliable.Can not influence mixed effect, the working environment cleaning has been eliminated potential safety hazard.Solved this technical barrier of mixing machine shaft end seal difference.
