Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further.
As shown in Fig. 1 to Fig. 3, a kind of polyurethane reaction still, it includes kettle 1 and the agitating device 2 stretching in kettle, also include chuck 3, forming airtight mezzanine space 4 between described chuck 3 and kettle 1, described mezzanine space 4 inner bottom part is provided with heater 5, is provided with heat transfer plate 6 between described heater 5 and kettle 1, being provided with reverse blower fan 7 between described heater 5 and heat transfer plate 6,6 mezzanine spaces 4 of described heat transfer plate are divided into circulating current chamber 8 and one-way gas flow chamber 9；Being provided with air inlet area 61 and district 62 of giving vent to anger relative to one-way gas flow chamber 9 on described heat transfer plate 6, bottom, described air inlet area 61 is provided with reverse blower fan 7, and described chuck 3 is externally provided with the drive mechanism 71 driving reverse blower fan 7；In such scheme, heater 5 discharges heat, reversely the air-flow in circulating current chamber 8 is sucked by blower fan 7, the air flow direction in one-way gas flow chamber 9 is made to give vent to anger district 62 enter in circulating current chamber 8 from district 62 of giving vent to anger, the air-flow making mezzanine space is formed and circulates, be equivalent to thermal current circulate along kettle, make kettle be heated evenly, reduce the temperature difference greatly.
In such scheme, described heater 5 is electrical heating coil pipe, by heater 5, the air in mezzanine space 4 is heated, so that the material in kettle 1 is heated, thus there is environmental protection, the uniform effect of heat conduction, the air inlet area 61 of heat transfer plate 6 and the design in district 62 of giving vent to anger make the steam in mezzanine space 4 form the circulating current surrounding kettle, thus improve the efficiency of heating surface, when kettle 1 needs to reduce temperature, kettle control system has only to close heater 5, reversely blower fan 7 is opened, the gas of flowing is continuously formed in making mezzanine space 4, flowing gas accelerates the reduction of temperature, in making still, temperature of charge is also minimized.
In this utility model embodiment, described heat transfer plate 6 is circular heat transfer plates, and branch is at heat transfer plate 6 two ends respectively for described air inlet area 61 and district 62 of giving vent to anger, and described air inlet area 61 is that some uniform and transversely arranged apertures 63 form；Described district 62 of giving vent to anger also forms for some apertures 63 uniformly and the most laterally arranged；A corresponding reverse blower fan 7 below described air inlet area 62, in such scheme, aperture 63 quantity in described district 62 of giving vent to anger is more than aperture 63 quantity of air inlet area 61, gas is flowed by aperture 63, because more than aperture 63 quantity of air inlet area 61, aperture 63 quantity in district 62 of giving vent to anger adds that reverse blower fan 7 is below air inlet area 62, because the quantity of air inlet area 61 aperture less than give vent to anger district 62 aperture quantity, so can guarantee that the thermal current in one-way gas flow chamber 9 is constantly being directed towards circulation in circulating current chamber 8, the temperature of retaining clip sheaf space 4.
In this utility model embodiment, described chuck 3 includes sealing coat 31, heat-insulation layer 32 and overcoat 33 from inside to outside；In such scheme, chuck 3 arranges multiple structure, not only increases its intensity, adds again the heat-insulating property of chuck 3.
In this utility model embodiment, described sealing coat 31 is stainless steel inner container, and described heat-insulation layer 32 is polyurethane insulation coating, and described overcoat 33 is stainless shell；In such scheme, described sealing coat 31 and overcoat 33 all use stainless steel, make chuck 3 have excellent intensity, and polyurethane insulation coating has good heat-insulating property and bonds the most firm with metal material.
In this utility model embodiment, described agitating device 2 includes shaft 21, be arranged on shaft 21 stirrer paddle 22 and drive the power set 23 that shaft 21 rotates, described stirrer paddle 22 includes H type stirrer paddle 221, paddle blade 222, pusher blade 223 from top to bottom, and described paddle blade 222 is provided with two-layer；nullIn such scheme，Pusher blade 223 is three blade push-paddle leaves，Enter material in kettle 1 through pusher blade 223 propelling with break up，Stirring by paddle blade 222，Finally stirred instead to rise to play by H type stirrer paddle 221 and material is carried out well-beaten effect，H type stirrer paddle 221 plays the effect of anchor formula stirring，Be conducive to material mixing in the axial direction，But owing to being shaped as H type，Less than common anchor formula stirring required drive，Two-layer paddle blade enhances the mixed effect of single paddle blade stirring，The setting from top to bottom of three types blade，Play the effect of compound stirring，Collection anchor impeller、The advantage of paddle blade and pusher blade is，Improve the effect of stirring mixing，Improve the uniformity of reaction，Shorten mixing time，Reduce stirring energy consumption，Improve productivity effect.
In this utility model embodiment, described pusher blade 223 is provided above filter screen 11；In such scheme, material is played the effect tentatively isolating separation by filter screen 11, facilitates follow-up stirring.
In this utility model embodiment, described kettle 1 top is provided with the manhole 12 of band visor；In such scheme, the visor on manhole 12 can facilitate operator to observe the response situation in reactor intuitively.
Every technical staff's notice: although this utility model describes according to above-mentioned detailed description of the invention; but invention thought of the present utility model is not limited to that utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
