Reaction unit
Technical field
The present invention relates to a kind of reaction unit.
Background technology
Great majority are not provided with agitating device for the reaction unit preparing printing and dyeing assistant on the market now, the material stirring making reaction is insufficient and uneven, it is slow that this just directly results in response speed, and reaction is not exclusively, waste resource, improve production cost, and after reaction, in tank, some reaction mediums under residual easily corrode, have impact on consersion unit, it is impossible to increase economic efficiency.
In order to solve the problems referred to above, Chinese utility model patent CN203123964U, disclose a kind of reaction unit for preparing printing and dyeing assistant, it is provided with the shaft being inserted in can body on cover, shaft bottom is provided with anchor blade, it is achieved the stirring to material, accelerates response speed.
But some printing and dyeing assistant has harmful substance to volatilize in preparation process, it is therefore desirable to be stirred in closed environment.Conventional belt stirring reaction device adopts the loss big, easy of packing seal or mechanical seal, gland sealed poor sealing performance and resistance mostly;Mechanical seal then price is high, and after using a period of time, sealing property declines, and safeguards that replacement cost is high.
Additionally, the heating environment that reaction needed is certain sometimes, tradition realizes the heating to material only by tank body heating, firing rate is slow and in tank temperature of charge uneven, be unfavorable for being smoothed out of reaction.
Summary of the invention
It is an object of the invention to: overcome the defect of above-mentioned prior art, it is proposed to a kind of reaction unit.
In order to achieve the above object, the reaction unit that the present invention proposes, composition includes can body, cover, stirring motor, shaft, stirring paddle, described can body is provided with dog-house, discharging opening, it is characterized in that: described cover central authorities offer circular hole, circular hole is fixedly arranged above support, it is provided with sealed spherical bearing in described support, the spheroid of described sealed spherical bearing connects shaft, the bearing housing of sealed spherical bearing and support are fixed, it is fixed with soft sealing film between described circular hole and spheroid, annular seal space is formed between described soft sealing film and support, pure water is filled in this annular seal space;Main electric heating tube is installed bottom described can body, can body inwall above described main electric heating tube is fixed with the nozzle towards obliquely downward to injection, it is fixed with pump mouth bottom can body below described main electric heating tube, described can body is outside equipped with the pipeline being connected by pump mouth with nozzle, pipeline is provided with water pump, in pipeline, is provided with auxiliary electrical heater pipe;Reaction unit also includes gas-heating apparatus and inserts several air inlet pipe of can body from bottom, described air inlet pipe is connected with the outlet side of gas-heating apparatus, the inlet end of described gas-heating apparatus connects noble gas source by pipeline, the air inlet pipe end inserting can body is provided with air dipelling disk, described air dipelling disk is positioned at below main electric heating tube, described cover is provided with exhaustor, equipped with relief valve on described exhaustor.
Reaction unit of the present invention, is further improved by:
1, described can body outer wall is provided with cooling chamber, and the top of cooling chamber has cooling water inlet, and the bottom of cooling chamber has coolant outlet.
2, described cover is provided with observation panel and the thermometer inserted in can body.
3, described soft sealing film is ringwise, and interior outside is tightly connected respectively through flange and spheroid, cover circular hole.
4, described cover is bonded with the seam of can body.
5, the injection direction of described nozzle is contrary with shaft rotation direction.
Reaction unit of the present invention uses ball bearing to realize the omnibearing stirring of stirring paddle, does not stay dead angle;Select flexible sealing film phonograph seal so that in inner pot, gas is not revealed, effectively protection operator and will not to environment;Owing to being marked with water in the annular seal space above diaphragm seal, therefore when pressure inside the tank changes, when particularly pressure is significantly increased or during pressure dramatic drop-off, diaphragm seal can be played good supporting role by annular seal space, this is because the volume of liquid is with changing hardly when ambient pressure changes, therefore diaphragm seal will not be heaved or subside, and also would not be subject to extra tension force, therefore not cracky, longer service life.
Therefore, the sealing infrastructure cost used by the present invention is cheap, and can bear pressure changes different in tank, has higher adaptability.
It is provided with main electric heating tube in the can body of present device, and auxiliary electrical heater pipe is set in the pipeline of water circulation, it is possible to material is heated.Water circulation has promoted the mixing of material, improves mixing effect, can material be heated by electric heating tube, it is achieved the purpose to heating material.Electrical heating be arranged in circulating line can to make heating object material evenly with mixing of materials in tank, make material evenly heated, improve response speed and the stationarity of material, improve production efficiency further.And pass into air inlet pipe bottom can body, utilize this air inlet pipe to pass through the noble gas of heating to can body delivered inside, it is possible to transfer heat to rapidly the material in can body;Due to the characteristic of gas fast upward motion of air inlet pipe input, contribute to material is produced convection current, make the heat of electric heating tube faster evenly pass to material.Air-flow and current combined effect, promote mutually, enable material to be sufficiently mixed, it is possible to the raising temperature of charge of even, improves reflection efficiency.
