QJB submersible mixer Product Description: Blue River diving submersible mixer is the introduction of the German motor sealing technology successfully developed. After years of practice and exploration, for its innovative in form, structure and test methods, making the overall performance submersible mixer reached the level of similar foreign products. Lanjiang QJB submersible mixer and mixing can be divided into two series of low-speed plug flow. Mixed Series mixer is suitable for sewage treatment plants and industrial processes stirred liquid containing suspended solids; low-speed plug-flow series mixer suitable for industrial and municipal wastewater treatment plant aeration tank, which produces low water flow tangential force can be used for circulation and nitrification, denitrification and phosphorus removal stage to create water and so on. Scope: Mixers under the following conditions should be normal continuous operation: a maximum medium temperature does not exceed 40 ° C; 2 PH value of the medium in the 5 to 9; 3 liquid density not exceeding 1150kg / m3; 4 long run diving, scuba diving depth of not more than 20m. Focus Note: Blue River diving fully submersible mixer necessary work; do not work in the environment flammable or corrosive liquids; steel bolts shall require fixed, after installation, you must tighten the cable fixed When diving push current selection, blade diameter of more than 2M, recommend the use of Gearbox machine Features: a compact structure, operation and maintenance is simple, easy installation and maintenance, long life; 2 impeller has the best hydraulic design structure. high efficiency, swept-back blade with self-cleaning function, can prevent wound debris clogging; 3 mixed with aeration system can significantly reduce energy consumption, significantly improve oxygenation effectively prevent precipitation; 4 motor windings class F insulation, protection class IP68, high quality bearings and motor anti-condensation device, so that the motor work safer; 5 two mechanical seals; Selection Note: submersible mixer selection is a more complex task , selection of correct or not directly affect the normal use of the device, as the principle of selection is to get fit to play in the volume mixer in full mixing function, generally available to determine the flow rate. According to the sewage treatment plant different process requirements, blenders should ensure optimal flow rate between 0.15 ~ 0.3m / s, the flow rate is less than 0.15m / s are not up to stirring effect plug flow, the flow rate of more than 0.3m / s of it will affect the results and wasteful process. So before the selection is first determined using submersible mixer places, such as: sewage, sludge pond, biochemical pool; followed by medium parameters, such as: suspended solids content, viscosity, temperature, PH value; there are pools of shape, water depth. Mixer required supporting power is based on the volume size, the density of the liquid and stir mixing depth determined, according to the specific circumstances of the use of one or more mixers. Mixing and stirring type 1 or FIG B1 Table B1 sludge correction coefficient determined in accordance with the medium to be stirred. 2 Determine the mixing tank pool type correction factor according to the table in Figure B2 or B2. 3 per cubic meter of water consumption required to power 5 w, multiplied by the correction factor sludge, multiplied by the pool-type correction factor, to be drawn per cubic meter mixing power consumption required for the actual value of the medium, and stir until then multiplied medium volume, draw the entire pool to be mixing medium power required. Low-speed plug-flow type 1 or Table B1 Figure B1 determine stirred tank-type correction factor based on a pool. 2 Determine the correction factor to be stirred sludge medium according to the table in Figure B2 or B2. 3 According to a stirred media initial velocity y, determined by the unit flow chart B3 power consumption. 4 with stirring medium is formed by multiplying the initial flow rate y of rotation of the impeller when the calculated cross-sectional area of ??the flow mixer. 5 multiplied by the power unit with mixer traffic flow, and then multiplied by the correction factor and sludge tank type correction factor required to obtain the entire pool of media power.
