Description

A kind of autoclave mixer

Technical field

The utility model is related to a kind of mixing plant, is stirred especially for a kind of autoclave of pigment printing binding agent preparation Mix machine.

Background technology

The quality of pigment printing product quality is directly influenceed by pigment printing binding agent performance, and pigment printing binding agent It is prepared from by pigment, adhesive, thickener, emulsifying agent and other additives etc..In order that each group in preparation process It is uniformly dispersed, generally requires to be stirred using mixing plant.A kind of existing conventional autoclave mixer, it includes stirring Kettle, kettle cover, it is inserted into the agitating device inside stirred tank through kettle cover, agitating device includes rotating shaft and scraped in the middle part of stirred tank The housing agitator of bottom scraping and two auxiliary agitators for being arranged on housing rotating shaft of stirrer both sides, two auxiliary The disperse blue of agitator and the height of bottom are inconsistent.Although this mixer can effectively prevent raw material prepare stamp glue Kettle wall and the bottom of stirred tank are sticked to during mixture, but it is difficult to accomplish stirred tank materials inside comprehensively balanced Ground is stirred, so its material stirring lack of homogeneity, and therefore badly influenced the quality of coating；And this kind of stirred tank is stirred Mixing device needs while using 3 motor drivings, therefore its structure is also complex, purchase cost is also higher.

The content of the invention

In order to overcome the deficiencies in the prior art, the utility model provides that a kind of mixing uniformity is good, simple in construction, cost Low autoclave mixer.

The utility model solves the technical scheme that its technical problem used：

A kind of autoclave mixer, include bottom be provided with the stirred tank of drain hole, be connected to the stirred tank above and Offer the kettle cover of dog-house, the agitating device inside the stirred tank, the agitating device bag are inserted into through the kettle cover The stirring for including the rotating shaft in the middle part of the stirred tank, being connected in the rotating shaft and being radially extended to the stirred tank kettle wall Oar, the base plate of scraping for being connected to the rotating shaft lower end, the agitating paddle have multi-disc and are staggeredly respectively in the rotating shaft both sides, up and down Distance between two pieces of adjacent agitating paddles in height is zero or partly overlaps, it is described scrape base plate lower end profile with it is described The bottom shape of stirred tank matches, the distance scraped between base plate and the agitating paddle of bottom in height be zero or Partly overlap；Motor is provided with above the kettle cover, the rotating shaft upper end is connected on the output shaft of the motor.

As the improvement of above-mentioned technical proposal, the horizontal groove of straight-through rear end face is provided with the agitating paddle front end face.

Further, the cross section of the horizontal groove is trapezoidal.

Further, the agitating device, which also includes, is connected to the agitating paddle end and the edge of a knife and the stirred tank kettle wall The scraping arm knife of contact, be connected to it is described scrape base plate lower end and the edge of a knife with the stirred tank bottom is contacted scrapes bed plate.

Further, circumferential uniform liquid distribution, the liquid distribution and water pump are provided with above the stirred tank kettle wall Connection.

The beneficial effects of the utility model are：Agitating device described in the utility model only needs a motor driving, thus Its structure is simpler, production and purchase cost are lower；Interlock to be respectively in described in the rotating shaft both sides by multi-disc simultaneously and stir Upper lower leaf stirring can be carried out to the material inside the stirred tank by mixing oar, and due to two pieces of neighbouring stirrings Distance between oar in height is zero or partly overlapped, therefore the revolution space of the agitating paddle can cover tight comprehensively The all materials covered inside the stirred tank, so that material obtains comprehensively balancedly stirring, the stirring for improving material is equal Even property, improve coating quality.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the sectional view of the agitating paddle shown in A directions in Fig. 1.

Embodiment

Reference picture 1, a kind of autoclave mixer of the present utility model, include bottom be provided with drain hole 11 stirred tank 1, It is connected to the top of stirred tank 1 and offers the kettle cover 2 of dog-house 21, is inserted into through the kettle cover 2 in the stirred tank 1 The agitating device 3 in portion, it is characterised in that：The agitating device 3 includes rotating shaft 31 positioned at the middle part of the stirred tank 1, connection The agitating paddle 32 that is radially extended in the rotating shaft 31 and to the kettle wall of stirred tank 1, it is connected to scraping for the lower end of rotating shaft 31 Base plate 33, the agitating paddle 32 has multi-disc and is staggeredly respectively in the both sides of rotating shaft 31, two pieces of neighbouring stirrings Distance between oar 32 in height is zero or partly overlaps, the bottom for scraping the lower end profile of base plate 33 and the stirred tank 1 Shape matches, and the distance scraped between base plate 33 and the agitating paddle 32 of bottom in height is zero or part weight It is folded；The top of kettle cover 2 is provided with motor 4, and the upper end of rotating shaft 31 is connected on the output shaft of the motor 4.This practicality is new Agitating device 3 described in type only needs a motor（Motor 4）Driving, thus its structure it is simpler, production and purchase cost more It is low；Simultaneously interlocked by multi-disc be respectively in the agitating paddle 32 of the both sides of rotating shaft 31 can be to the stirred tank 1 inside Material carries out upper lower leaf stirring, and because the distance between two pieces of neighbouring agitating paddles 32 in height is zero Or partly overlap, therefore the revolution space of the agitating paddle 32 can cover the institute inside the stirred tank 1 tight comprehensively There is material, so that material obtains comprehensively balancedly stirring, improve the mixing uniformity of material, improve coating quality.

Set to further strengthen mixing effect and mitigate on the weight of the agitating paddle 32, the front end face of agitating paddle 32 It is equipped with the horizontal groove 321 of straight-through rear end face.

Reference picture 2, the cross section of the horizontal groove 321 is trapezoidal.The horizontal groove 321 is set to it is trapezoidal, can To change by the flow velocity of the relatively described agitating paddle 32 of material of the horizontal groove 321 during stirring, improve stirring Effect；For example when mixing direction is direction shown in Fig. 1 dotted arrows, due to flowing of the material in the horizontal groove 321 Area is gradually decreased, therefore material will be also stepped up by the flow velocity of relatively described agitating paddle 32 during the horizontal groove 321.

Bottom scraping effect is scraped in order to strengthen the agitating device 3, and the agitating device 3, which also includes, is connected to described stir Mix the end of oar 32 and scraping arm knife 322 that the edge of a knife is contacted with the kettle wall of stirred tank 1, be connected to and described scrape the lower end of base plate 33 and the edge of a knife With the bottom of stirred tank 1 is contacted scrapes bed plate 331.

Circumferential uniform liquid distribution 5 is provided with above the kettle wall of stirred tank 1, the liquid distribution 5 connects with water pump 6 It is logical.Said structure can facilitate to be cleaned after stirring operation to the stirred tank 1 and agitating device 3, it is to avoid coating prints Flower adhesive is condensed on the stirred tank 1 and agitating device 3 after drying.

The above is better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, As long as it reaches technique effect of the present utility model with any same or similar means, protection model of the present utility model should be all fallen into Within enclosing.
