Description
Technical field
The invention belongs to the mixing plant technical field, more particularly, belong to a kind of equipment for stirring mud in the sludge fermentation tank.
Background technology
In last century, producer generally adopts diving mixer and vertical mixer that large-scale sludge fermentation tank is carried out uniform stirring both at home and abroad; There are the problems such as installation, maintenance, waterproof and anticorrosion in diving mixer.When adopting vertical mixer, need motor to provide very high power for shaft; Require simultaneously material and the intensity of the shaft of vertical mixer also to propose higher requirement.
In order to solve machine mixer operation high-speed smooth, to be convenient to the problems such as installation capability and maintenance, taken the lead in researching and developing the through-the-wall mixer abroad and be applied to carry out in the sludge fermentation tank uniform stirring of mud feed liquid to the beginning of this century, the through-the-wall mixer comprises power section, mixing part, support section, power section is motor, the mixing part is agitator arm and shaft, and support section is played a supporting role to the mixing part; Power section can link to each other by decelerator or belt pulley with the mixing part; The power section of through-the-wall mixer is in the outside of fermentation tank.The through-the-wall mixer uses when the sludge fermentation tank, because the agitator arm of mixing part is in the inside of fermentation tank, the weight of himself is very large; In case when power section, shaft or the central siphon of mixer break down in some cases, how in the situation that do not emit mud feed liquid in the fermentation tank, do not change the agitator tank internal impeller, get rid of the fault of mixer, it is the difficult problem of restriction the art.
Summary of the invention
The present invention has provided a kind of sealing device of through-the-wall mixer in order to solve above technical problem.
The sealing device of a kind of through-the-wall mixer of the present invention is characterized in that: comprise end cap, blade cover, seal cartridge, gland, the first rubber seal, bearing holder (housing, cover), sleeve pipe, the first screw, bearing, the second screw, the second rubber seal, metal o-ring, inboard shaft, inboard central siphon; Wherein:
Bearing holder (housing, cover) is sleeved on the inside of inboard central siphon; Inboard shaft is fixed on the bearing holder (housing, cover) by bearing; Gland is fixed on the inboard central siphon by the second screw; The first rubber seal is arranged between bearing holder (housing, cover) and the gland; Seal cartridge is sleeved on the inboard shaft, and the second rubber seal is arranged between seal cartridge and the bearing.
One end of end cap and inboard shaft links together by key, and the blade cover is installed on the end cap by the first screw.
Blade is sleeved on blade and puts, and the integral body that blade, blade cover, end cap, inboard shaft form is rotated around central siphon.Having between seal cartridge and the bearing has the first rubber seal can guarantee to have preferably sealing between gland and the bearing holder (housing, cover) between the second rubber seal, bearing holder (housing, cover) and the gland, and then reaches bearing is sealed.
Mixer of the present invention can be opened central siphon rear end, the outside when needs keep in repair, and so just can easily outboard shafts be unloaded from shaft, and then intermediate connecting shaft is also unloaded down.
The present invention is compared with prior art: have simple in structure, safety and stability, maintenance activity efficient advantages of higher.
