Description
Technical field
The utility model relates to a kind of wet mixing pelletizer, relates in particular to the paddle hermetically-sealed construction of wet mixing pelletizer.
Background technology
Wet mixing pelletizer is the special equipment that in the life of medical industry tablet, medicinal powder, starch, adhesive is carried out to wet-mixing granulation.Also the granular material that is applicable to food, chemical industry mixes and granulates.For granulator, because the mixture of the material entering and water may be acid, may be alkalescence, the cleaning of granulator is necessary, once not wash clean clearly meeting contaminated material, serious words may cause scrapping of material, the noresidue therefore granulator cleaning is totally necessary, as on fruit structure with dead angle, material in production process, if water etc. enter in dead angle, cannot clean up, wet mixing pelletizer generally comprises pedestal, cylinder body, stirring system, and granulating system, stirring system is by stirring transmission device, paddle and sealing device composition, because the sealing device structure of traditional stirring system is comparatively complicated, easily there is cleaning dead angle, and sealing effectiveness is also bad, raw material in the time of stirring system rotation work in cylinder body still easily enters sealing device, along with raw material impurity is piled up in sealing device, faster to the sealing device wearing and tearing between the stirring system rotating, and to clean whole wet mixing pelletizer before the different material of each processing, the sealing mechanism that comprises stirring system in cylinder body and stirring system also needs to clean, traditional stirring system is in the time cleaning, paddle need to be pulled down from stirring transmission device, just can expose sealing device, and sealing device is cleaned, for relatively large wet mixing pelletizer, the paddle of its equipment is also larger and heavier, pull down cleaning again load onto again use all need to be by lifting appliance, comparatively inconvenient, affect cleaning efficiency.
Summary of the invention
The purpose of this utility model is the defect existing for prior art, and the wet mixing pelletizer of a kind of good seal performance, easy to clean, the cleaning in place of paddle hermetically-sealed construction energy is provided.
For achieving the above object, the utility model adopts following technical proposals: a kind of wet mixing pelletizer with the cleaning in place of paddle hermetically-sealed construction energy, comprise cylinder body, stirring system and granulating system, stirring system comprises shaft, paddle and sealing device, shaft one end is stretched in cylinder body, the shaft other end is driven by stirring motor, one end that shaft stretches in cylinder body is connected with paddle and drives paddle to rotate, sealing device is located between paddle and shaft, described sealing device comprises sealing shroud, upper sealing ring, lower sealing ring, described sealing shroud is fixed on cylinder body, sealing shroud is the bowl structure of upper end open, sealing shroud is provided with axis hole, shaft is connected with paddle through axis hole, between sealing shroud upper end and paddle lower end, be provided with upper sealing ring, between the axis hole position of sealing shroud and shaft, be provided with lower sealing ring, sealing shroud, shaft and paddle form annular seal space, sealing shroud is provided with import and outlet, described import is communicated with water source and annular seal space, described outlet communication seals chamber and the external world.
The beneficial effects of the utility model are, sealing shroud in sealing device adopts the bowl structure of opening upwards, sealing shroud upper end open and paddle lower end are realized and being sealed and matched by upper sealing ring, shaft drives paddle to rotate through the axis hole of sealing shroud lower end, the sealing at axis hole place relies on lower sealing ring to realize, thereby form with sealing shroud, shaft and paddle are the annular seal space on border, and on sealing shroud, offer import and outlet, realizing annular seal space is in communication with the outside, in the time of wet mixing pelletizer machining state, can close outlet, simultaneously connect air pump toward gas injection pressurization in annular seal space at opening part, and keep barotropic state in annular seal space, making gas in air pump enter annular seal space enters in cylinder body from upper sealing ring again, and rotate in paddle and the upper sealing ring between sealing shroud play most sealing function, but owing to being two sealings between mutual tumbler, there are unavoidably fine particle or liquid to permeate toward annular seal space from upper sealing ring, now the barotropic state in annular seal space just can well play the effect of hermetic seal, be that upper sealing ring place has gas to blow out toward cylinder body from annular seal space always, stop fine particle or liquid to permeate toward annular seal space from upper sealing ring, reach good sealing effectiveness, and while needing sealing device to clean in cleaning process, only need to flow into cleaning fluid in opening, making cleaning fluid enter annular seal space cleans, and a part of cleaning fluid enters cylinder body by upper sealing ring place, realize the cleaning to upper sealing ring place, after cleaning, cleaning fluid unnecessary in annular seal space is discharged extraneous by exit, complete the cleaning of whole sealing device, in this cleaning process without paddle is just pulled down and can sealing device be cleaned, clean very convenient.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
