Description
Technical field
The utility model belongs to production of resins technical field, particularly relates to a kind of condensation kettle producing polyvinyl butyral resin.
Background technology
Because China's manufacturing is fast-developing, domestic demand constantly expands, the naval stores that the products such as polyvinyl butyral resin (PVB) resin and Related product extensive market are antifouling paints, copper-clad plate (circuit board), enamel-covered wire, coating, safety interlayer glass must use.The current main production process of polyvinyl butyral resin utilizes inorganic acids to work as catalyst, makes polyvinyl alcohol and hutanal carry out dehydration condensation and make in condensation kettle.In the condensation process due to the difference of feed way, the difference of whipped form and cause the resin shape size formed to have very large difference.
Existing feed way directly adds from still top feeding mouth, and whipped form is generally push type or paddle.Still top directly reinforced can cause adding butyraldehyde or hydrochloric acid local concentration too high, can not disperse rapidly in the short time just to start reaction, form the caking of material, unequigranular, affects the quality of final products.Pusher stirring belongs to axial flow type, although internal circulating load is large, turbulent extent is not high, partial cut scarce capacity, although paddle stirs shear effect, internal circulating load is little well.Due to the problems referred to above, and cause produced resin particle uneven, easily wrap up hydrochloric acid or butyraldehyde in particle, cause later process processing difficulties.
Utility model content
The resin particle that the technical problems to be solved in the utility model is to provide a kind of mixing effect good, obtained produces the condensation kettle of polyvinyl butyral resin uniformly.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of condensation kettle producing polyvinyl butyral resin, comprise kettle, agitator, the top of described kettle arranges polyvinyl alcohol and hydrochloric acid charging aperture, the sidewall of kettle arranges the first butyraldehyde charging aperture, the second butyraldehyde charging aperture and the 3rd butyraldehyde charging aperture, the bottom of kettle arranges discharging opening, described agitator comprises power set, shaft, paddle impeller, pusher impeller, power set are arranged on kettle, power set and shaft are in transmission connection, shaft stretches in kettle, shaft is installed paddle impeller and pusher impeller.
The utility model produces the condensation kettle of polyvinyl butyral resin, and wherein said first, second, third butyraldehyde charging aperture is set in qually spaced on the sidewall of kettle from top to bottom.
The utility model produces the condensation kettle of polyvinyl butyral resin, and the top mounting flange formula thermometer of wherein said kettle, thermometer stretches in kettle.
The utility model produces the condensation kettle of polyvinyl butyral resin, and wherein said paddle impeller and pusher impeller are respectively equipped with two, and two paddle impellers and two pusher wheel space are arranged on shaft.
The utility model produces the condensation kettle of polyvinyl butyral resin, the outer setting shell body of wherein said kettle, shell body is fixedly connected with kettle, between shell body and kettle, there is cavity, the top of the sidewall of shell body arranges cooling water inlet, the bottom of shell body sets out the mouth of a river, and cooling water inlet, delivery port communicate with cavity respectively.
The utility model produces the condensation kettle of polyvinyl butyral resin, the sidewall of kettle is arranged first, second, third butyraldehyde charging aperture, adopt side charging mode, and three charging apertures are set, substantially reduce jitter time, improve dispersion effect, agitator comprises paddle impeller and pusher impeller, employing combined type stirs, namely ensure that internal circulating load, in turn ensure that shear effect, adopt above-mentioned feed way and combination agitating mode, obtained naval stores density is large, uniform particles, acid number is low, easily washes, good dissolving, facilitates the use of downstream client.
Be described further below in conjunction with the condensation kettle of accompanying drawing to production polyvinyl butyral resin of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model produces the condensation kettle of polyvinyl butyral resin.
