Abstract
The utility model relates to a mixer with a rotary stirring device in a fixing container, particularly to a mixer with a stirrer rotating around a vertical shaft. A new apparatus for chitosan production and solid-liquid reaction has a reaction kettle provided with an interlayer, a mesh-shaped reaction filter is arranged in the reaction kettle, and the stirrer is arranged in the reaction filter. In the utility model, reaction and separation are combined into a whole, and the utility model has the advantages of simple and safe operation, easy control of reaction conditions, sufficient recovery and utilization of solution, high productive efficiency, low labor intensity, etc. The utility model can be used in various solid-liquid reactions and can also be used for the construction of a flow production line of chitin.
Description
The utility model relates to the mixer that has gyratory agitation device in fixed container, especially has the mixer around the agitator of a vertical axis rotation.
Current, shitosan production adopt 60～170 ℃ greater than 40% caustic soda medium in carry out the deacetylation reaction, carry out Separation of Solid and Liquid, washing then.Existing equipment and technology usually behind the reactor internal reaction, are carried out centrifugal or other filter separates again, exist that equipment complexity, quality are wayward, operating personnel are easily reclaimed disadvantages such as difficulty by burn, solution.
The purpose of the utility model is to provide a kind of novel chitosan production and the solid-liquid reaction device that can fully recycle with that separate, easy to operate and safe, easy control of reaction conditions, solution that can be used to simultaneously react.
Shitosan production and solid-liquid reaction new clothes are equipped with the reactor of a strap clamp layer, and the filter response of a mesh is housed in the reactor, and agitator is housed in the filter response.
Below in conjunction with embodiment shown in the drawings, the utility model is explained in detail.
Accompanying drawing 1 is the utility model front view, and accompanying drawing 2 is the utility model vertical views, and accompanying drawing 3 is the utility model filter response bottom front views.
Shown in accompanying drawing 1 to 3, shitosan production and solid-liquid reaction new clothes are equipped with the anti-of a sandwich Answer still 1, the filter response 5 of a mesh shape is housed in the reactor 1, be equipped with in the filter response 5 and stir Mix device 3. Reactor 1 is common stainless steel interlayer reactor, can lead to Steam Heating or water flowing cooling. Drain hole is arranged at the bottom of reactor 1, connects baiting valve. Alignment pin 7 is arranged at the top of reactor 1. Reaction The netted stainless steel material of filter 5 usefulness or hole shape stainless steel material are made, the aperture 0.5～8mm of mesh About. The height of filter response 5 and diameter are more smaller than reactor 1. The top of filter response 5 Be fixed on the suspension bracket 6, the hole that cooperates with alignment pin 7 is arranged on the suspension bracket 6. Stirring in the filter response 5 Device 3 is driven by the motor 4 that is installed on the suspension bracket 6.
As shown in Figure 3, the bottom of filter response 5 is movable. The bottom of filter response 5 Formed by the semicircle stainless steel filtering net 8 of two slit bamboo or chopped woods and support 9. Semicircle stainless steel filtering net 8 can be independently around Support 9 rotations. During charging, fixing with hasp 10, unclamp embarkation 10 during discharging and get final product.
As shown in Figure 1, agitator 3 is around a vertical axis revolving. Can be anchor agitator, can To be spiral agitator, also can be that anchor agitator adds spiral agitator, can also be other stir Mix device. The rotating speed of agitator 3 is advisable with 40～70r/min.
Shown in attached Fig. 1 and 2, thermowell 2 is equipped with on the top of filter response 5 and reactor 1.During chemical reaction, thermometer is inserted in the thermowell 2 of filter response 5.When chemical reaction finishes, before the filter response 5 of slinging, thermometer is inserted in the thermowell 2 of reactor 1.
Application example: the soda lye that in reactor 1, drops into 40～60% concentration, filter response 5 is contained in the reactor 1, again steam is fed reactor 1 interlayer, make the temperature that soda lye is warming up to be needed, start agitator 3, slowly drop into chitin, control certain temperature, behind the reaction certain hour, stop to stir, with crane lifting filter response 5, make its bottom hang liquid level 100～200mm, alkali lye is drained substantially.Filter response 5 is winched in the reaction pot or other liquid bath of another dress water again, start agitator 3, stirred 5～10 minutes, cyclic washing is to neutral, dry.Through the reaction of deacetylation, can the output deacetylation reach the product more than 80%, viscosity can be controlled at 20～500 or more than the 500pas as required.
This device can be used for other reaction.In different medium, use, adopt different materials to make, as stainless steel, RPP plastics, enamel, metal spraying plastics or other corrosion resistant coatings etc.
Obviously, the utility model collection reacts, is separated into one, has easy to operate and safe, easy control of reaction conditions, solution can fully be recycled, the production efficiency height, advantages such as labour intensity is low can be widely used in all kinds of solid-liquid reactions, also can be used for the streamline production of chitin.
In the embodiment shown in the figures, the appearance and size of reactor 1 is φ 1450 * 2100, and the appearance and size of filter response 5 is φ 1240 * 1450, adopts stainless steel filtering net to make, and screen distance is 3mm.The top of agitator 3 is spiral agitators, and the bottom is an anchor agitator.The appearance and size of suspension bracket 7 is 2100 * 300.
