Description

The through-the-wall mixer

Technical field

The invention belongs to the mixing plant technical field, more particularly, belong to a kind of equipment that is used to stir mud in the sludge fermentation jar.

Background technology

In last century, producer generally adopts diving mixer and vertical mixer that large-scale sludge fermentation jar is evenly stirred both at home and abroad; There are problems such as installation, maintenance, waterproof and anticorrosion in diving mixer.When adopting vertical mixer, needing motor is that shaft provides very high power; Require the material and the intensity of vertical mixer shaft also to propose higher requirement simultaneously.

In order to solve machine mixer operation high-speed smooth property, to be convenient to 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 jar the even 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 a motor, and 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 through decelerator or belt pulley with the mixing part; The power section of through-the-wall mixer, mixing part are all in the outside of fermentation tank.

The through-the-wall mixer uses when high solids (8%-12%) sludge fermentation jar, because the agitator arm of mixer is in the inside of fermentation tank, the weight of himself is big; Shaft axis body length is longer, and there is the big shaft problem such as big of wearing and tearing that contacts with mud of poor stability, vibrations in the through-the-wall mixer when high-speed cruising; And when in case the power section of mixer in some cases or shaft break down, particularly when shaft breaks down, how under the situation that does not emit mud feed liquid in the fermentation tank, to get rid of the fault of mixer, be the difficult problem in restriction present technique field.

Summary of the invention

The present invention has provided a kind of through-the-wall mixer in order to solve above technical problem.

Through-the-wall mixer of the present invention comprises power section, mixing part, support section, and power section links to each other with the mixing part, and the mixing part is installed on the support section; It is characterized in that: the shaft of said mixing part is sleeved in the central siphon of support section, and shaft is split type multistage axle.

Through-the-wall mixer of the present invention comprises power section, mixing part, support section, and power section links to each other with the mixing part, and the mixing part is installed on the support section; It is characterized in that: said shaft comprises inboard shaft, intermediate connecting shaft, outside shaft; Inboard shaft, intermediate connecting shaft, outside shaft are sleeved in the central siphon of support section; Wherein: inboard shaft and intermediate connecting shaft link together through first shaft coupling, and outside shaft and intermediate connecting shaft link together through second shaft coupling.

Central siphon near power section the rear axle cover is installed, the middle part is equipped with lubricating cup.Inboard shaft, intermediate connecting shaft and outside shaft all are sleeved in the central siphon through bearing and hermetically-sealed construction.

Through-the-wall mixer of the present invention uses inboard shaft and outside shaft together support intermediate connecting shaft; Let inboard shaft, outside shaft, intermediate connecting shaft be sleeved in the central siphon simultaneously through shaft coupling and hermetically-sealed construction; Can improve the rigidity and the linearity of the whole shaft of forming by inboard shaft, outside shaft, intermediate connecting shaft greatly; Whole shaft rigidity is high, linearity is good, vibrations are little, transmission efficiency is high, has effectively improved stability, mixing effect that shaft exists when high-speed cruising.

After using mixer of the present invention; The agitator arm of mixer can be installed in the inside of fermentation tank; Even the weight of the agitator arm of mixer self is big, shaft axis body length is longer, through-the-wall mixer of the present invention stability when high-speed cruising is very good, vibrations obviously reduce, the wearing and tearing of mud contact shaft obviously reduce.

In some special situation; When breaking down like the power section of mixer or shaft; Particularly when shaft breaks down; The fault that can under the situation that does not emit mud feed liquid in the fermentation tank, get rid of mixer directly solves the corresponding techniques problem through removing intermediate connecting shaft and outside shaft.Mixer of the present invention can be opened the axle cover of central siphon back when needs keep in repair, and just can easily intermediate connecting shaft and outside shaft be unloaded down from central siphon, so just can realize the maintenance to middle connecting axle and outside shaft.

The present invention is compared with prior art: have simple in structure, safety and stability, maintenance activity efficient advantages of higher.
