Description

A kind of mechanical seal agitating device
Technical field
The present invention relates to a kind of mechanical seal agitating devices.
Background technology
The present mechanical seal agitating devices for being used to prepare printing and dyeing assistant most of on the market are not provided with agitating device, make The material stirring that must be reacted is insufficient and uneven, and it is slow that this just directly results in reaction speed, and reacts incomplete, wastes money Source improves production cost, and some reaction mediums after reaction in tank under residual easily corrode, and affect consersion unit, no It can increase economic efficiency.
To solve the above-mentioned problems, 203123964 U of Chinese utility model patent CN disclose one kind and being used to prepare print The mechanical seal agitating device of dye auxiliary agent is equipped with the agitating shaft being inserted into can body, the installation of agitating shaft bottom end on cover There is anchor blade, realize the stirring to material, accelerates reaction speed.
However certain printing and dyeing assistants have harmful substance to volatilize in preparation process, it is therefore desirable to be carried out in closed environment Stirring.Conventional belt Mixing Machine sealed stirring device mostly uses greatly packing seal or mechanical seal, the sealing performance of packing seal Poor and resistance is big, is easily lost；And then price is high for mechanical seal, sealing performance declines after a period of use, safeguards replacement cost It is high.
In addition, reaction sometimes needs certain heating environment, tradition that can only be realized to material by being heated to tank body Heating, heating speed is slow and tank in temperature of charge it is uneven, be unfavorable for being smoothed out for reaction.
Invention content
It is an object of the invention to：The defect for overcoming the above-mentioned prior art proposes a kind of mechanical seal agitating device.
In order to achieve the above object, mechanical seal agitating device proposed by the present invention, composition includes can body, cover, stirring Motor, agitating shaft, agitating paddle, the can body are equipped with feeding port, discharge port, it is characterised in that：The cover center opens up circle Hole, circular hole are fixedly arranged above holder, and sealed spherical bearing, the sphere connection of the sealed spherical bearing are provided in the holder Agitating shaft, bearing housing and the holder of sealed spherical bearing are fixed, and soft sealing film is fixed between the circular hole and sphere, described Seal chamber is formed between soft sealing film and holder, and pure water is filled in the seal chamber；The can body bottom is equipped with main electrical heating It manages, the can body inner wall above the main electric heating tube is fixed with the nozzle towards the injection of direction obliquely downward, the main electric heating tube lower section Can body bottom be fixed with pump mouth, be provided with the pipeline for connecting pump mouth with nozzle outside the can body, be equipped on pipeline Water pump is provided with auxiliary electrical heater pipe in pipeline；Mechanical seal agitating device further includes gas-heating apparatus and is inserted into from bottom Several air inlet pipe of can body, the air inlet pipe are connected with the outlet side of gas-heating apparatus, the air inlet of the gas-heating apparatus End connects noble gas source by pipeline, and the air inlet tube end for being inserted into can body is equipped with air dipelling disk, and the air dipelling disk is located at master Below electric heating tube, exhaust pipe is installed on the cover, relief valve is housed on the exhaust pipe.
Mechanical seal agitating device of the present invention, further improve are：
