Industrial agitator Wikipedia

An agitator is composed of a drive device ( motor, gear reducer, belts), a guiding system of the shaft (lantern fitted with bearings), a shaft and impellers . If the operating conditions are under high pressure or high temperature, the agitator must be equipped with a sealing system to keep tightened the inside of the tank when the shaft is

Problems in Stock Agitation James Brinkley

Baffling of Tanks to Produce Top to Bottom Agitation. Tank baffles are necessary in some vertical agitator applications. Stock at consistencies above 3-3.5% is self baffling. Stock will swirl when consistency is less than 2.5-3%. If swirling starts, mixing will be ineffective, and top to bottom motion that produces complete mixing will cease.

Agitation an overview ScienceDirect Topics

Agitation plays an essential role in the success of many chemical processes, and there is a wide range of commercially available impellers that give optimum agitation for any process (see Figures 7-6, 7-9, and 7-10). The problem arises in selecting the best impeller for the required process.

CHAPTER 9. AGITATION AND MIXING

• Agitation: It refers to the induced motion of a “homogenous” material in a specified way • Mixing: It is the random distribution, into and through one another, of two or more initially separate phases PURPOSES OF AGITATION • Suspending solid particles • Blending miscible liquids

Oct 25, 2017 IMPELLERS Impellers in agitated tanks are used to mix fluids or slurry in the tank. This can be used to combine materials in the form of solids, liquids and gas. Mixing the fluids in a tank is very important if there are gradients in conditions such as temperature or concentration. 16.

The hydraulic jet type is operated by a pressure line hooked into the spray system directly behind the pump. The hydraulic jet agitator should be positioned in the tank to provide agitation throughout the tank. A flow of 5 to 6 GPM for each 100 gallons tank capacity is usually adequate for an orifice jet agitator.

May 04, 2014 However, at the end of the batch, CO 2 evolution almost stops, so the pump or agitator must blend the tank and keep solids in suspension to the extent possible. The tank size is 198” (5.03m) diameter, shallow bottom, with a working volume of 40,800 gallons (154 m 3). Tank contents have an average specific gravity of 1.0. Pump Description

Mar 13, 2009 March 17, 2009. A. Assuming typical hardcoat bath operating conditions of 32 °F, Ted is correct. Air agitation would be a heat load due to the higher ambient temperature and the heat of compression. If you use a water cooled condenser with a cooling tower, the compressor discharge condensing temperature will be lower than outside air due to the evaporative cooling described by Ted.

Feb 18, 2011 A typical sparger will produce a 6- to 9-inch zone of effective agitation. Agitation can also be provided by pumping the solution. Pumps should be sized to provide 4 to 6 tank turnovers/hr. Eductors can be used to enhance solution flow at the workpiece. Exhaust ventilation is required to capture fumes generated at the tank.
