Multifunctional dispersing reaction kettle appearance standa

Each a multifunctional dispersing reaction kettle after all safety monitoring of the state, each reaction kettle has the security test, below is the high-pressure reaction kettle to factory standard is as follows:
1, multifunctional reactor operating normally, good effectiveness: 1) mechanical drive without a murmur, mixer and equipment within the heating coil, pressure pipe components should be collisionless and gaps in accordance with provisions; 2) multifunctional reactor operating normally, no abnormal vibration; 3) multifunctional dispersed reaction kettle stirring motor temperature is normal, bearing temperature should comply with the provisions; 4) high pressure reaction kettle magnetic seal and pipes, pipe fittings, valves and so on without any leakage.
2, multi-function dispersed inside the reaction kettle parts without damage, quality requirements: 1) mixer, both inside and outside the main parts of the coil and so on material selection in accordance with the drawings requirements; 2) multifunctional dispersing the reaction kettle body, shaft seal, mixer, both inside and outside the main parts of the coil and so on installation, wear and corrosion limit should comply with the regulations of maintenance and repair procedures; 3) scattered multifunctional reactor lining in leakage, not bulge, coil unit within the fastening and reliable.
3, multi-function dispersed reaction kettle body clean, zero accessories complete works: 1) the multi-functional scattering reaction kettle relief valve, control valve, control instrument, ventilation, explosion-proof, security protection facilities such as sensitive to use, and shall regularly check check; 2) multifunctional scattering reaction kettle pipe fittings, pipe, valves, installation, such as stents is reasonable, the horizontal flat vertical, color is obvious; 3) multifunctional dispersing reaction kettle all bolts shall be filled with buckles, neat, tighten.
4, how to improve the multifunctional dispersing reaction kettle agitator power
How to improve the multi-function dispersed reaction kettle agitator power?
Multifunctional dispersed reaction kettle agitator flow state of the power and groove, so the factors influencing the flow state of the inevitable reaction kettle agitator power is also affected. Reaction kettle geometric parameters and operating parameters of mixer, slurry, pulp, wide blade Angle, speed, number of blades, the blade from the bottom of the channel installation height and so on. Reaction kettle stirring tank geometric parameters: tank diameter, depth of liquid, baffle width, number of baffle, diversion tube size, etc. The physical parameters of mixing medium: the density of liquid liquid phase viscosity and gravity acceleration, etc.
Because the multi-function to spread the power from the reaction kettle mixer blender itself geometric parameters of the operation condition to study its power consumption, so in the influence factors can not see the effects of different mixing purpose. In other words, as long as these parameters are the same, don't ask what is mixing process, the resulting reaction kettle agitator power are the same. These factors can be classified into the known as plasma, groove geometry, plasma operating variables and physical variables which influence power. Try to find these variables and power relations, also is the problem of agitator power calculation.
A scattered, multi-functional reaction kettle numeral relations in blender power calculation:
Multifunctional dispersing the influence of the reaction kettle agitator power variable is so large that make it very difficult for research work. Power is not the same, the influence of these variables should be found which is the main influence factors, and also some variables should be defined the scope of the study.
To figure out the relationship between influencing factors and power, are currently using the similarity theory and the method of dimensional analysis, it can be related to a large number of variable geometry, operation and physical variables into a few meaningful can be used as design basis of dimensionless number. Similarity theory of a kind of practice is to first establish a mathematical relation type mixing flow state, and then the relation type rewritten into a dimensionless form.
As we know, mixing the flow of the medium, shall comply with the quality and the law of conservation of momentum. In certain type Newton fluid density, said local stress and local velocity relationship is nai nai d a stokes equations can be d a dimensionless form of stokes equations. For that we can paste diameter as a characteristic length measurement, the agitator rotational speed as a feature of time from bottom, and the liquid density plasma diameter of cubic product features as a quality, will product as the characteristic of blade diameter and stirring speed measurement, and then export the dimensionless pressure and dimensionless velocity, substitution nai d a stokes that its dimensionless form. Can be seen from the dimensionless equation and dimensionless pressure, substitution nai d a stokes equation for a quick its dimensionless form. Can be seen from the dimensionless equation and dimensionless velocity and dimensionless pressure are two dimensionless number group - ray between numeral and functions. One said the ratio of the fluid inertia force and viscous force, said the ratio of the fluid inertia force and gravity.
Power is agitator rotational speed and the distance of the product, and the torque can be from the local stress distribution of blade surface, so that you can find out the relationship between the dimensionless.
Second, the whole baffle conditions:
By the above known, baffle is to change the slot flow state in a stirred tank accessories. The wall is vertical baffle more research. Experiments show that the width of the baffle, number and installation France can affect flow, also can affect the size of the power.
Most powerful agitator, the baffle condition called the baffle. Also can say so, when baffles are eligible for the whole baffle, even add attachments, agitator power is no longer increasing. It is generally believed that take 4 piece of damper and its width can be close to the baffle conditions.
Groove set other can hinder the level rotary flow artifacts such as coil can baffle the role. In the absence of baffle device, when other stationary components meet can also be credited with the role of the damper. Coefficient is called baffle conditions. All internals type in the direction perpendicular to the liquid circulation projection area combined. Some agitator in the groove of eccentric installation or tilt insertion, borrow the tank wall effect also can have the effect of the damper.
