Description
Technical field
The present invention relates to technical field of environment protection equipment, particularly to the processing means of mud.
Background technology
Before sludge dewatering, sludge conditioning to be carried out, so-called sludge conditioning is also referred to as the chemical conditioning of mud.Sludge condensation is general only
Its moisture content can be made to drop to about 85%, moisture content will be reduced further, reduce volume it is necessary to separate out mud combines moisture
Come, namely make this part water that the adhesive force of solid particle is weakened, make granule unstability grow up.Way generally used now is at mud
Mud quenched pond is set before filter pressing, is used for mud is carried out chemical conditioning, adds the organic-inorganic flocculant such as ferric chloride, Calx,
The flocculant effect sludge flocculation time is typically at 5-10min.And mud quenched pond floor space and output investment ratio are relatively big, flocculant with
The mixing of mud typically uses slow-speed of revolution dasher or Double-curved-surface stirring device, and mixed effect is undesirable.
Summary of the invention
The applicant, for the disadvantages mentioned above of prior art, studies and improves, it is provided that a kind of based on discharge pressure monitoring regulation
Sludge mixer, it greatly improves the mixed effect of flocculant and mud.
In order to solve the problems referred to above, the present invention uses following scheme:
A kind of sludge mixer based on discharge pressure monitoring regulation, including mixing kettle, the bottom side of mixing kettle is entered with muddy water
Material pipe, the top of its opposite side is provided with muddy water discharge nozzle, and muddy water feed pipe is connected with feeding engine；Mixing kettle is provided with agitating device,
Described agitating device includes the shaft being obliquely installed in mixing kettle, and shaft is with hollow structure, and its sidewall spacers is provided with
Blade and pod apertures, described pod apertures is between adjacent blade；The upper end of shaft is with flocculant feed pipe and by cone
Gear assembly is connected with motor, and motor is installed on the end face of mixing kettle by support；
Being provided with pressure monitor in described muddy water discharge nozzle, pressure monitor is connected with the input of electric machine controller, motor control
The outfan of device processed is connected with motor, and electric machine controller controls the rotating speed of motor according to the pressure signal of pressure monitor；Described pressure
Power monitor is also connected with the feeding controller of feeding engine, and feeding controller controls feeding engine according to the pressure signal of pressure monitor
Feeding pressure.
The method have technical effect that:
In the present invention, flocculant uses the importing of the shaft being obliquely installed, and quickly throws away, itself and mud while importing
The good mixing effect of water, speed are fast；Use Real-time Monitor Technique, it is achieved Intelligent adjustment speed of agitator and feeding pressure, it is not necessary to people
Industry control system, its mixing effect is more preferably.

Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As it is shown in figure 1, the sludge mixer based on discharge pressure monitoring regulation of the present embodiment, including mixing kettle 1, mixing kettle 1
Bottom side with muddy water feed pipe 2, the top of its opposite side is provided with muddy water discharge nozzle 3, muddy water feed pipe 2 and feeding engine
12 connect；Being provided with agitating device in mixing kettle 1, agitating device includes the shaft 5 being obliquely installed in mixing kettle 1, stirring
Axle 5 is with hollow structure, and its sidewall spacers is provided with blade 4 and pod apertures, and pod apertures is between adjacent blade 4；Stir
Mixing the upper end of axle 5 and be connected with motor 8 with flocculant feed pipe 6 and by bevel gear assembly 7, motor 8 passes through support 9 and pacifies
It is loaded on the end face of mixing kettle 1；
Being provided with pressure monitor 10 in muddy water discharge nozzle 3, pressure monitor 10 is connected with the input of electric machine controller 11,
The outfan of electric machine controller 11 is connected with motor 8, and electric machine controller 11 controls electricity according to the pressure signal of pressure monitor 10
The rotating speed of machine 8；Pressure monitor 10 is also connected with the feeding controller 13 of feeding engine 12, and feeding controller 13 is according to pressure
The pressure signal of monitor 10 controls the feeding pressure of feeding engine 12.
When the present invention uses, sludge water enters in mixing kettle 1 from muddy water feed pipe 2, and flocculant is from flocculant feed pipe 6
Enter mixing kettle 1, mix under the stirring action of agitating device；Flocculant adds from flocculant feed pipe 6, is stirring
Mix under the centrifugal action under the guide effect of axle 5 and when shaft 5 rotates, infiltrate into equably in sludge water, with muddy water
Uniformly mix；Pressure monitor 10 monitors the discharge pressure in muddy water discharge nozzle 3 in real time, and sends pressure signal to control
Device 11 processed, controller 11 regulates the rotating speed of motor 8 in real time.
In the present invention, flocculant uses the importing of the shaft being obliquely installed, and quickly throws away, itself and mud while importing
