Description
Technical field
The utility model relates to the equipment that is used for hydrolysis reaction, specifically a kind of equipment that is used for the hydrolysis of polyacrylamide reaction.
Background technology
The equipment that is used for the hydrolysis of polyacrylamide reaction at present is large-scale hydrolysis machine for one type, and another kind of is single screw rod blender.The volume and the power of hydrolysis machine are bigger, and in use are the intermittent hydrolysis of a still one still.The shortcoming that existing large-scale hydrolysis machine exists is: 1, equipment has high input, and energy consumption is high, and efficient is low; 2, batch production, the quality product fluctuation is big; 3, because the volume of equipment is big, stirring system is big, and viscosity is big during the hydrolysis of polyacrylamide reaction, so the stir shaft of equipment twists off easily.
Single screw rod blender is compared with large-scale hydrolysis machine, invests lessly, and energy consumption is lower; But because polyacrylamide gel particles has viscosity, the SEPIGEL 305 that hydrolysis goes out is sticked together, and single screw rod can only be pushing away before its integral body; Do not had the blended effect, or blended effect extreme difference, in addition; Because polyreaction generally can only make the temperature of blob of viscose rise to below 75 ℃, the thermosteresis when adding granulation, the temperature that micelle gets into single screw rod blender will drop to below 65 ℃; Such temperature can not satisfy the requirement of hydrolysis reaction, though the storage tank of single screw rod blender can satisfy the HYDROLYSIS OF POLYACRYLAMIDE AND ITS COPOLYMERS residence time, SEPIGEL 305 is the poor conductor of heat; Even also be difficult to reach the hydrolysis temperature requirement for storage tank heat, visible, adopt single screw rod blender; The product molecular weight distribution that obtains is inhomogeneous, product is poorly soluble, is difficult to obtain the quality high product.
The utility model content
The purpose of the utility model is to provide a kind of SEPIGEL 305 continuous-hydrolysis reactor, and less investment, the energy consumption of this hydrolysis reactor are low, and can guarantee to have the ideal hydrolysis temperature, realizes the continuous hydrolysis reaction.
For realizing above-mentioned purpose, the utility model adopts following scheme: the SEPIGEL 305 continuous-hydrolysis reactor, and the leading section upside of a cylindrical shell has opening for feed, the rearward end downside has discharge port; One stir shaft stretches in the cylindrical shell; Stir shaft is positioned at the outer end of cylindrical shell and connects with PWR PLT, is furnished with some groups of blades on the stir shaft vertically, is attached with spiral pusher blade more than two sections on the stir shaft; Each section pusher blade and two groups of above blades are separation; Outside at cylindrical shell is with chuck, is formed with cavity between chuck and cylindrical shell, and the downside that the upside of chuck one end has water-in, the other end has water outlet.
Visible by such scheme, drive the stir shaft running by PWR PLT, the polyacrylamide gel particles after the granulation and liquid or solid-state caustic soda are got into cylindrical shell from opening for feed; In chuck, inject hot water by the water-in on the chuck; Discharge hot water by the water outlet on the chuck, to the cylindrical shell heating, reaction mass is advanced, is stirred down by blade and react by pusher blade in cylindrical shell; Blade has guaranteed mixing of reactant; Pusher blade has guaranteed the reaction times and the pusher speed of material, guarantees that material is not detained in equipment, and the material after reaction is accomplished is discharged from the discharge port on the cylindrical shell; Simultaneously the hot water in the chuck can replenish the required heat of hydrolysis reaction, make reaction can be fully, complete.
The utility model is rational in infrastructure, use is reliable, the constant product quality of acquisition, and its less investment, energy consumption is low, production efficiency is high, and maintenance rate is low.
