Description
Technical field
The invention belongs to industrial waste water treatments, more particularly, to a kind of industrial wastes processing unit.
Background technique
A large amount of waste water will be generated in industrial processes, these waste water can not be directly discharged in external environment, be needed
It after treatment, just being capable of normal discharge.It when containing acid in waste water, is needing to make by neutralizing the acid ion in removal waste water
It obtains waste water and reaches discharge standard.In and when, usual way is to be neutralized using lime to waste water, due to lime be easy it is heavy
Bottom, when neutralization, need to be stirred using agitating device.But the mixing effect of existing agitating device is poor, lime remains unchanged
It is easy to appear phenomenon is sunk to the bottom, so that reacting between lime and waste water is not enough, neutralization is influenced.And driving stirring dress
It generallys use cylinder when setting mobile directly to be driven, cylinder is easy to happen damage, and service life is short.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides one kind and stirs evenly, at industrial wastes with long service life
Manage device.
To achieve the goals above, the invention adopts the following technical scheme: a kind of industrial wastes processing unit, including pond
Body the waste liquid inlet being connected with pond body, neutralizes feed inlet, waste residue outlet, stirs set on the intracorporal agitating device in pond and with this
Mix the driving device that device matches；The driving device includes the first driving portion for driving the agitating device to move up and down
Part and for drive the mixing component or so act the second driving part；The agitating device includes master arm, is spaced apart
In the mixing arm on the master arm and the agitating paddle component being rotatably arranged on the mixing arm；The agitating paddle component and stirring
The power-assist structure for reducing frictional force between the two is equipped between arm；Second driving part include the second actuator,
The drive rod that reduction, turntable and the one end being connected with second actuator are connected with the turntable, the drive rod other end and institute
It is hinged to state master arm.Mixing arm is respectively driven in upper and lower, left and right by the first driving part and the second driving part in the present invention
Movement on two different directions guarantees that the waste liquid in neutralization pond is sufficiently stirred in mixing arm, when liquid in neutralization pond
It carves and is in disturbance state, be not in the case where lime is sunk to the bottom, guarantee that lime comes into full contact with and reacts with waste water, neutralization
It is good and high-efficient；Since agitating paddle component can be rotated relative to mixing arm, thus during mixing arm moves left and right, stirring
Paddle component can rotate, to reduce the resistance of motion that mixing arm is subject to, so that the second driving part is easier to driving master arm
It acts, lower-powered model can be used in the second driving part, saves electric power resource；The setting of power-assist structure can reduce
Agitating paddle component rotation when mixing arm between frictional force, thus further reduce mixing arm when moving left and right by
Resistance, further save energy consumption；Meanwhile power-assist structure can also reduce the abrasion between agitating paddle component and mixing arm, extend
The service life of equipment；The drive rod is connected at the eccentric position of the turntable, by the connection of eccentric manner, realizes the
Two actuators are in rotation, the movement being able to drive on the master arm generation left and right directions, without flinging shape by cylinder
Formula drives master arm mobile, and equipment is more simple, and motor is hardly damaged, and the service life is longer.
Further, the agitating paddle component includes the external member of C-shaped configuration, is spaced apart in the agitating paddle in external member and sets
In the removable component in external member, the external member inner surface is equipped with Connection protrusion, and the mixing arm is equipped with and the Connection protrusion phase
The open channel of cooperation, the power-assist structure are set in the Connection protrusion；By the cooperation of Connection protrusion and open channel, realize
Positioning to agitating paddle effectively prevent agitating paddle appearance position on mixing arm mobile；Effectively external member is locked by removable component
It is scheduled on mixing arm, prevents external member appearance position mobile；And by the setting of removable component, also enable agitating paddle component phase
Mixing arm is dismantled, is conveniently replaceable, the service life of equipment entirety is extended.
Further, the power-assist component includes the annular receiving groove being set on the Connection protrusion outer surface, is placed in this
Rolling member in annular receiving groove covers at the Anti-slip cover outside the Connection protrusion and the fixing piece for positioning the Anti-slip cover；Rolling
Moving part can the rolling when agitating paddle rolls, effectively reduce the frictional force between Connection protrusion and open channel；Anti-slip cover is logical
It crosses fixing piece to be fixed in Connection protrusion, so that rolling member be effectively prevent to deviate from from holding tank.
Further, the circle for being pierced by the Anti-slip cover outer surface for the rolling member that is equipped with being spaced on the Anti-slip cover is opened
Mouthful, the diameter of the circular open is less than the diameter of the rolling member；The limit played the role of by circular open to rolling member,
It effectively prevent rolling member to be rolled to be bonded to each other together, rolling member is more uniformly spread, and the effect for reducing frictional force is more preferable；And
Also rolling member is effectively prevent mutually to collide and generate sound, reduces noise when equipment work.
Further, the Anti-slip cover is made of aluminium, the fixing piece be two circlips, the Connection protrusion be equipped with
Two card slots that the fixing piece matches；Aluminium has certain ductility, so that Anti-slip cover is by circlip clamping when circlip clamping
Position can deformation occurs so that circlip is caught in into card slot, effectively prevent circlip by deviating from Connection protrusion.
Further, the agitating paddle is to be obliquely installed, and multiple leakage through slots are intervally distributed on the agitating paddle；Inclination is set
It sets so that agitating paddle can drive more liquid to move up when moving up and down, enhances stirring efficiency；Leakage through slot can reduce stirring
The resistance being subject to when paddle moves up and down, the first driving part energy consumption is lower, and is hardly damaged.
Further, first driving part includes bracket on the neutralization pond, the on the bracket
One actuator, the connection frame matched with the master arm, the driving section for connecting the connection frame and first actuator
Part.
Further, the connection frame side wall is equipped with the idler wheel matched with the bracket, and the master arm end is arranged in
In the connection frame, the roller matched with the master arm is equipped in connection frame.
In conclusion the invention has the following advantages that mixing arm can be in upper and lower, the two enterprising action of different directions in left and right
Make, sufficiently, neutralization is good, and high-efficient for stirring；Agitating paddle component can rotate during mixing arm moves left and right,
Reduce the resistance of motion that mixing arm is subject to, reduces the energy consumption of the second driving part；Power-assist structure can reduce agitating paddle component and turn
Frictional force when dynamic between mixing arm, further resistance, and the abrasion between agitating paddle component and mixing arm can be reduced, extend
The service life of equipment；The rotation of second actuator can drive the master arm that the movement on left and right directions occurs, without passing through
The form that flings of cylinder drives master arm mobile, and equipment is more simple, and motor is hardly damaged, and the service life is longer.
