Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

As shown in fig. 1-3, the utility model discloses be provided with in the reactor and add hopper 1, it is linked together with reducer pipe 2 to add hopper 1 below, one side that adds hopper 1 is provided with liquid inlet 14, water conservancy diversion piece B15 has been arranged in liquid inlet 14 department, water conservancy diversion piece a13 has been arranged at the periphery of reducer pipe 2 import department, fixedly connected with goes out air cavity 11 on water conservancy diversion piece a13, it is provided with flange connector 111 to go out air cavity 11 top, be linked together with spiral blender 3 at the lower extreme of reducer pipe 2, the lower extreme of spiral blender 3 is linked together with blender 3, the below of blender 3 is provided with base 5, be provided with material inlet 41 in blender 3, spiral blender 3 lower extreme is connected with material inlet 41, material inlet 41 is linked together with mixing chamber 42, be provided with multistage stator 421 and cutting impeller 422 in mixing chamber 42, cutting impeller 422 is connected with transmission shaft 61, transmission shaft 61 is connected with motor 6, the end and the material outlet 43 of mixing chamber 42 are linked together and are provided with one-level seal 45 at the end of mixing chamber 42, and be provided with cooling chamber 442 at one-level seal 45, be provided with cooling chamber 44 at cooling chamber on cooling water outlet 46 simultaneously, be provided with cooling water inlet 46.

The utility model discloses the principle does: powder material adds to adding hopper 1 from adding hopper 1 top, because the setting of water conservancy diversion piece A13 and going out the arrangement of air cavity 11, powder material is cyclic annular and adds to adding hopper 1, liquid material adds to adding hopper 1 from liquid inlet 14, because water conservancy diversion piece B15's setting, make liquid material be the tangential outflow, and drive powder material and flow in reducing pipe 2, whole in-process has realized premixing to solid-liquid material, go out air cavity 11's setting, to in can producing gaseous reaction, the gaseous play air cavity 11 that rises of in-process formation, and it is outer through the flange connector 111 connection outlet duct that goes out air cavity 11 top.

The feeding hopper 1 is an initial stage of solid-liquid mixing, materials are easily bonded in the process, so that blockage occurs, the solid-liquid ratio needs to be controlled, the adding amount of powder materials and the flow rate of liquid materials are controlled, reasonable selection is carried out according to the actual material conditions in the process, only the fact that powder can be rapidly and completely taken away and flows into the reducer pipe 2 needs to be guaranteed, at the moment, mixed fluid is in a trickle state, gaps can exist in the fluid and are not beneficial to subsequent further mixing, therefore, the materials flowing into the reducer pipe 2 need to be further enriched in the reducer pipe 2, in order to guarantee the enrichment effect, certain requirements are placed on the size of the reducer pipe 2, the ratio of the upper end to the lower end of the reducer pipe 2 is preferably 2-3:1 in actual use, the ratio of the length of the reducer pipe to the diameter is preferably 1.5-2:1, and at the moment, the materials continuously flow into the spiral mixer 3.

The materials flowing into the mixing materials 3 are further mixed in the spiral mixer 3, and in the process of adding the materials into the spiral mixer 3, the materials descend and flow by the gravity of the materials, so that the flow continuity is ensured, meanwhile, more energy is saved, the flow state of the fluid can be broken through by the rotation of the mixing materials in the spiral mixer 3, the mixing degree is increased, and the primary mixing process is realized, certain requirements are met on the screw pitch of the spiral mixer 3 in the primary mixing process, when the screw pitch is too small, the back mixing phenomenon is easy to occur, when the screw pitch is too large, the mixing effect is influenced, the screw pitch corresponds to the flow rate of the mixing materials, namely the processing amount of the materials, for one reactor, the processing amount is certain, so that the corresponding screw pitch can also be determined, when the reactor is actually used, the screw pitch-diameter ratio of the screw mixer is 0.8-1.5, when the reactor is in different specifications, the size of the spiral mixer is changed, but the integral amplification is only, and the ratio of the screw pitch-diameter cannot be changed.

The material that flows through spiral blender 3 flows to in blender 4, and the flow state in the mixing material is broken under the effect of cutting impeller 422 in mixing chamber 42, the further turbulence degree of material has been increased, thereby make the material mix more even, the final mixing has been realized, in order to guarantee the effect of mixing, cutting impeller 422's quantity is the key, when cutting impeller 422 quantity is tertiary in practice, it is respond well, although the further increase mixes the effect and promotes, but not obvious, the corresponding volume that still can increase the reactor, and then the cost is increased, simultaneously to motor 6, the energy consumption has also been increased, use in not benefiting production.

Because cutting impeller 422 passes through motor 6 and drives, then be provided with one-level seal 45 between mixing chamber 42 and the motor drive shaft 61, at motor 6 pivoted in-process, one-level seal 45 department can produce the heat, in order to guarantee sealed effect, need cool down to sealed department, the setting of cooling chamber 44 can be realized to and the cooling of sealed 45 department, thereby guarantee the stable operation of reactor, because the setting of cooling chamber 44, cooling chamber 44 right side also need set up sealedly, second grade is sealed 46, also the cooling chamber 44 has realized the cooling of one-level seal 45 and second grade sealed 46 department promptly.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products with various forms can be obtained by anyone under the teaching of the present invention, but any changes in the shape or structure thereof, all having the same or similar technical solutions as the present application, fall within the protection scope of the present invention.
