Abstract
The invention provides a vacuum kneader. The vacuum kneader comprises a vacuum system, and the vacuum pipeline of the vacuum system is connected with an emptying valve on a cylinder cover. A seal measure in various forms, which is adopted by the vacuum kneader, is characterized in that: silicon rubber seal strips fixed on the cylinder cover are used to seal a space between a cylinder body and the cylinder cover of a kneading part; a mechanical shaft seal containing a polytetrafluoroethylene seal ring is sealed between the shaft and the bearing of a transmission system; and there is a sealed connection between the emptying valve and the vacuum pipeline of the vacuum system through polytetrafluoroethylene seal pads and a stainless steel ripple soft joint, wherein above seal parts are coated with a silicone seal ointment. The vacuum kneader of the invention has the advantages of good seal effect in the cylinder body, vacuum degree of 0.03-0.09Mpa, strong corrosion resistance, suitableness of the use of various component materials, low cost, and convenient operation.
Description
Technical field
The present invention relates to kneader, refer in particular to a kind of kneader that contains vacuum system that adopts multiple seal means.
Background technology
Usually, kneader partly is made up of kneading portion, support part, hydraulic system, transmission system and electric-control system etc.Common kneader, the cylinder body of kneading portion are to be connected with the open of atmosphere UNICOM with cylinder cap, and this mediates for the demanding material of air-tightness is infeasible, needs vacuum kneader.But general vacuum kneader is because the seal approach of a plurality of mechanical parts is not in place, the vacuum >=0.09Mpa of system, and effect is not very good.
The number of applying for a patent discloses a kind of vacuum kneader for the specification of 200620057740.X, and it only is equipped with seal box on shaft, vacuum extractor is not arranged, and the gas that produces in the material will cause can not reaching vacuum preferably in the cylinder body.And its encapsulant is not selected the material of corrosion resistance especially for use, and is inapplicable to the kneading of severe corrosive material.
Summary of the invention
Goal of the invention: overcome the lower defective of vacuum of traditional kneader, a kind of good sealing effect, high, the corrosion resistant vacuum kneader of vacuum are provided.
Technical scheme: for realizing the object of the invention, kneader contains parts such as kneading portion, body part, hydraulic system, transmission system and electric-control system, and body partly contains cylinder cap and cylinder body.Kneader also contains the vacuum system that vacuumizes, and the vacuum pipe of vacuum system is connected with emptying valve on the cylinder cap.Following manner is adopted in the sealing of kneader: one, adopt the silastic sealing strip sealing that is fixedly connected on the cylinder cap between the cylinder body of body part and the cylinder cap; Two, adopt the mechanical shaft seal sealing that contains teflon seal ring between the axle of transmission system and the bearing; Three, the emptying valve adopts stainless steel ripple connecting hose to be connected with vacuum pipe, respectively contains a slice polytetrafluoroethylene sealing gasket sheet between the flange plate of the flange plate at stainless steel ripple connecting hose two ends and the flange plate of emptying valve and vacuum pipe;
Among the present invention, when vacuum system vacuumized, vacuum was between 0.03Mpa～0.09Mpa;
On aforesaid sealing strip, sealing ring or the gasket seal; Scribble the silicone seal ointment; The silicone seal ointment is to be the synthetic sealing cement of main component with the silicone resin; Have good hear resistance, oxidative resistance and chemical reaction stability, the use of fitted seal parts can further improve sealing and vacuum.
Described silastic sealing strip fixed method on cylinder cap is: embedding groove is reserved in the cylinder cap side, contains jut on the silastic sealing strip, can be embedded in the embedding groove.
Beneficial effect: the good sealing effect in the cylinder body of kneader of the present invention, vacuum is high, and corrosion resistance is strong, is fit to the use of multiple composition material.Teflon seal ring and polytetrafluoroethylene sealing gasket sheet have corrosion resistance, wearability preferably, and self lubricity is good, coefficient of friction is little, has plasticity and elasticity preferably in addition, when mechanical shock is big, still keep good sealing property.Cost of the present invention is lower, and kneading and vacuum pumping are convenient.
Description of drawings
Accompanying drawing is a partial structurtes sketch map of the present invention;
Among the figure, 1, cylinder cap; 2, silastic sealing strip; 3, jut; 4, embedding groove; 5, emptying valve; 6, polytetrafluoroethylene sealing gasket sheet; 7, flange plate; 8, stainless steel ripple connecting hose; 9, vacuum pipe.
The specific embodiment
