The a mixing bowl that the steady mixing building of a kind of water is equipped with

Technical field

The present invention relates to the part of the mix equipment of road building machine, be specially a mixing bowl that the steady mixing building of a kind of water is equipped with.

Technical background

Mostly a mixing bowl of the steady mixing building outfit of 700 tons/hour water in the market is trapezoidal linerless board-like, and length is between 3.6-3.9 rice, and between the width 1.4-1.6 rice, type of belt drive is that motor passes through the type of belt drive that belt drives reductor.This kind mix cylinder in use since length short, do not have liner plate again, cause the compound of mix inhomogeneous, power output is on the low side, belt needs often to change, and changes difficulty, simultaneously problems such as mill colander body easily.

Summary of the invention

Of the present invention PurposeJust be to provide a kind of water a mixing bowl that steady mixing building is equipped with, it mixes cylinder transformation to existing on the basis that as far as possible utilizes members such as original motor of mixing cylinder, reductor, blade; Make it power output raising, the reinforcement of mix ability; The mix effect is even, and the pot body is wear-resisting, and production capacity can reach the requirement of design output; The solution power output is low, mix is inhomogeneous, improve wearability, increases the purpose in service life.

The present invention realizes what the foregoing invention purpose was adopted Technical schemeFor:

The a mixing bowl that the steady mixing building of a kind of water of the present invention is equipped with; Comprise a mixing bowl support, a mixing bowl pot body and the MIXING SYSTEM CONTROLLED BY that is provided in a mixing bowl pot body is installed and installation is provided in and is positioned at the external dynamical system of pot on a mixing bowl support, dynamical system is to MIXING SYSTEM CONTROLLED BY output mix power; Said dynamical system comprises two motors, connects reductor, the synchronous transmission gear that is connected with reductor with two motors are connected respectively; Said MIXING SYSTEM CONTROLLED BY comprises a mixing bowl pot body, sets to be installed in two agitators that are made up of shaft, mixing arm, paddle arranged side by side in pot body; It is characterized in that: said a mixing bowl pot body is set to W type structure; A mixing bowl pot body length is made as between the 4.1-4.5 rice; Width is made as between the 1.6-1.8 rice; The place that on internal wall pot body, is in the stirring area position is provided with the thick wear resistant cast iron liner plate of one deck 180mm-220mm, according to the physical dimension of a mixing bowl pot body, the corresponding supporting agitator that shaft, mixing arm, blade constituted is installed in it; Shaft adopts the solid 45# steel of diameter 190-230mm to make; Mixing arm adopts the solid 45# steel of diameter 55-70mm to make; Pass shaft welding, the setting angle of mixing arm is respectively six kinds of 0 degree, 60 degree, 120 degree and 30 degree, 90 degree, 150 degree on the diaxon; The mixing arm two ends are welded with the protector of mounting blades, leave the rectangle screw of mounting blades on the protector, and blade pass is crossed bolt and is connected with the protector of mixing arm, forms agitator jointly; Motor is connected through shaft coupling with reductor in the said dynamical system, and reductor connects synchronous transmission gear through shaft coupling, and the step travelling gear is located in the synchronous gear box.

Of the present invention Beneficial effectFor:

The present invention adjusts the drive mechanism of motive power system, with the belt transmission between motor and the reductor, changes the shaft coupling transmission into.It is easy to maintenance to change the back, needs only to change to connect with bolt, and the elephant hide band does not connect requirement mobile motor when changing, and original position is being installed back.Simultaneously durable in use, more the situation of throwing switch can not appear, improved power output.

The present invention has carried out big change to MIXING SYSTEM CONTROLLED BY: 1, with the pot shape by the trapezoidal W type that changes into; 2 increase the wear resistant cast iron liner plate in the pot body; 3 are adjusted into the pot body length between the 4.1-4.5 rice, between the width 1.6-1.8 rice, make shaft length according to new adjusted length simultaneously, and number of fitting parts such as corresponding mixing arm, blade.The present invention can prolong by the duration of mixing of Forced Mixing material in mixing cylinder through the change to the pot body; Change shape simultaneously; Increase liner plate and reduced the gap between blade and liner plate, fines adhesion pot body can not occur, the situation that causes material proportion to change; Can guarantee that more mix is even, simultaneously because the use of liner plate has increased the wearability of mixing pot.

It is following that the present invention improves the back summary of benefits:

1, former mix cylinder and change the shaft coupling transmission into by belt transmission after, solved the problem of throwing switch, power obviously strengthens, and through using six months damaged condition not occur, changes the situation of 1-2 belt when comparing former belt transmission every half a year, the minimizing maintenance frequency;

2, mix behind the cylinder alteration of form with the track of the blade of rotation approachingly, better drive the compound motion, moreover lengthening mixes cylinder, increased stirring vane, the mixing time of compound in mixing pot prolonged, the mix effect is better evenly;

3, can reach the highest design output through check mix ability in the use, and mechanical movement is respond well.Process is produced the wearing and tearing of 300,000 tons of rear lining plates between 2.0-5.0mm, satisfies durable, wear-resisting requirement.
