The manufacturer supplies wx-1000 stainless steel mixing drum and stainless steel mixer reaction kettle
Stainless steel agitators are widely used in coating, medicine, building materials, chemical industry, pigment, resin, food, scientific research and other industries. The equipment can be made of carbon steel, stainless steel and other materials according to the process requirements of users\' products, and heating and cooling devices can be set to meet different process and production needs. The heating forms include jacketed electric heating and coil heating. The equipment has the characteristics of reasonable structure design, process, durability, simple operation and convenient use. It is an ideal chemical equipment with low investment, fast production and high income.
Type of agitator
① The propeller agitator is composed of 2 ~ 3 propelling propeller blades (Fig. 2). The working speed is high, and the peripheral speed of the outer edge of the blade is generally 5 ~ 15m/s. The propeller agitator mainly causes axial liquid flow and generates large circulation volume. It is suitable for mixing low viscosity (< 2PA · s) liquids, emulsions and suspensions with solid particle content less than 10%. The rotating shaft of the agitator can also be inserted into the tank horizontally or obliquely. At this time, the circulating circuit of the liquid flow is asymmetric, which can increase turbulence and prevent the liquid level depression.
② The stainless steel mixing drum agitator is composed of 2 ~ 4 flat or curved blades installed on the horizontal disc (Fig. 3). The ratio of the outer diameter, width and height of the blade is generally 20:5:4, and the circumferential speed of the stainless steel mixing drum is generally 3 ~ 8m/s. The highly turbulent radial flow caused by the rotation of the turbine is suitable for the dispersion of gas and immiscible liquid and the liquid-liquid phase reaction process. The viscosity of the stirred liquid generally does not exceed 25Pa · s.
③ There are two types of paddle agitators: flat paddle and inclined paddle. The flat paddle agitator is composed of two flat paddles. The ratio of blade diameter to height is 4 ~ 10, the circumferential velocity is 1.5 ~ 3m/s, and the radial flow velocity is small. The two blades of the inclined paddle agitator (Fig. 4) turn 45 ° or 60 ° opposite to each other, resulting in axial liquid flow. Paddle agitators are simple in structure and are often used for mixing low viscosity liquids and dissolving and suspending solid particles.
④ The shape of the outer edge of the anchor agitator blade and the inner wall of the mixing tank shall be * (Fig. 5), and there is only a small gap between them, which can remove the viscous reaction products attached to the tank wall or the solids accumulated at the bottom of the tank, so as to maintain a good heat transfer effect. The peripheral speed of the outer edge of the blade is 0.5 ~ 1.5m/s, which can be used to stir Newtonian and pseudoplastic fluids with viscosity up to 200Pa · s (see viscous fluid flow. Only when stirring high viscosity liquids, there is a large stagnant zone in the liquid layer.
⑤ The outer diameter and pitch of the ribbon of the ribbon agitator are equal (Fig. 6). It is specially used to stir high viscosity liquids (200 ~ 500pa · s) and pseudoplastic fluids. It is usually operated in laminar flow.
⑥ The magnetic stirrer Corning digital heater is equipped with a closed-circuit knob to monitor and adjust the mixing speed. The microprocessor automatically adjusts the motor power to adapt to water quality, viscous solution and semi-solid solution.
⑦ The magnetic heating stirrer Corning digital heating stirrer has an optional external temperature controller (cat. No. 6795pr), which can also monitor and control the temperature in the container.
Heating or cooling device
Generally, the user unit depends on whether the material is heated, dried or cooled. Within the customized range, the temperature shall be below 200 ℃ and the service pressure shall be lower than 0.1MPa. The heating method can be determined according to the production conditions of the user. There are two heating methods: hot oil and other media circulation and direct electric heating. The circulation of hot oil and other media is that the heat transfer oil is heated to a certain temperature in another configured heating tank, and then transported and circulated through the hot oil pump; Direct heating means that an electric heating pipe is directly installed on the jacket to heat the heat transfer oil to the required temperature (the temperature can be adjusted according to the actual situation). Cooling circulation is to use water to circulate inside and outside the jacket, so that the material will not produce caking or viscosity at a certain temperature. Coil can also be added for heating or cooling according to user requirements.
