Abstract
The utility model relates to a mixer, in particular to a sealing mechanism for the shaft end of a mixer. The sealing mechanism comprises a sealing seat (4) and a sealing cover (1) which are all sleeved on a main shaft (5), wherein the sealing cover (1) is connected with the end surface of one side of the sealing seat (4); and a packing (2) is arranged between the sealing cover (1) and the sealing seat (4). The sealing seat (4) is provided with a through hole (4-1); and the through hole (4-1) is provided with an air inlet (3). With the adoption of the structure, the sealing mechanism has the beneficial effects that on the basis of an original seal, a gas sealing structure is further additionally formed on the shaft end of the mixer, so that the structure is simple; a double seal is adopted, so that the shaft end of the main shaft of the mixer is prevented from powder spraying, the sealing effect is good, the shaft end of the mixing equipment is prevented from powder spraying, and the sealing is safe and reliable; and the mixing effect can not be affected, the working environment is clean, and the potential safety hazards are eliminated.
Description
Technical field
The utility model relates to a kind of mixer, particularly a kind of mixer shaft end seal mechanism.The utility model belongs to mixing machinery device fabrication processing technique field.
Background technology
Mixer 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.Mixer generally rotates through the main shaft that power drives mixer, 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 mixer wallboard in mixer; Mechanism seals main-axis end through the mixer shaft end seal; Can not scurry out with material in the assurance mixer mixed process, so the main-axis end sealing mechanism is the important component part of mixer from main-axis end.Existing mixer shaft end seal mechanism, referring to Fig. 2, its structure generally comprises seal receptacle and the seal cover that is sleeved on the main shaft, and seal cover is connected on the side end face of seal receptacle, is provided with packing between seal cover and the seal receptacle.Existing mixer shaft end seal mechanism also exists following defective: adopt mechanical seal, and the weak effect of sealing, main-axis end exists the phenomenon of dusting, and influence mixed effect, 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 prior art, a kind of simple in structure, good sealing effect is provided, prevents that the mixing apparatus axle head from dusting, the reliable mixer shaft end seal of sealingly secure mechanism.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of mixer shaft end seal mechanism; Include the seal receptacle and the seal cover that are sleeved on the main shaft, seal cover is connected on the side end face of seal receptacle, is provided with packing between seal cover and the seal receptacle.Have through hole on the described seal receptacle, the through hole is provided with intake interface.
Further, also include sealing gasket, sealing gasket is arranged on the opposite side end face of seal receptacle.
Further, described packing material is rubber or wool felt.
Further, described seal cover is fixedly connected on the side end face of seal receptacle through screw.
Owing to adopt technique scheme, the utlity model has following beneficial effect: the utility model is owing to have through hole on the seal receptacle, and the through hole is provided with intake interface.This structure makes the mixer axle head that uses the utility model on the basis of original sealing; Further increased the hermetic seal structure again, simple in structure, the utility model adopts dual-seal; Prevent that the mixing apparatus main-axis end from dusting; Good sealing effect prevents that the mixing apparatus axle head from dusting, and sealingly secure is reliable.Can not influence mixed effect, the working environment cleaning has been eliminated potential safety hazard.
