Submersible jet mixer QJB4/4-1800/2-42/P

QJB4/4-1800/2-42/PSubmersible jet mixerSuitable for stirring liquids containing suspended solids in sewage treatment plants and industrial processes, suitable for aeration tanks in industrial and urban sewage treatment plants, it produces strong water flow with low tangential flow, which can be used for circulation, nitrification, denitrification, and phosphorus removal stages to create water flow, etc.

The submersible thruster has a compact structure, small volume, and light weight. The operation and maintenance are simple, the installation is convenient and fast, and the service life is long. The blades have self-cleaning function, which can prevent debris from winding and blocking. When used in conjunction with the aeration system, it can greatly reduce energy consumption, significantly increase oxygen filling, and effectively prevent sedimentation. The motor winding is F-class insulation with a protection level of IP68. It uses maintenance free imported bearings with oil chamber leakage detection and motor winding overheating protection function, making the motor work safer and more reliable. The friction material of the mechanical seal is corrosion-resistant tungsten carbide, and all fasteners are made of stainless steel, suitable for various water treatment processes and industrial processes that require maintaining a uniform mixing reaction of solid and liquid phases or solid, liquid, and gas three-phase media.

QJB4/4-1800/2-42/PThe submersible jet mixer can operate continuously under the following conditions: 1. The maximum medium temperature does not exceed 40 ° C; The pH value of the two media is between 5-9; 3. The density of the medium does not exceed 115KG/M ^ 3; Long term diving operation of low-speed thrusters, with a diving depth generally not exceeding 20 meters. The selection of submersible thrusters is a complex task, and the correctness of the selection directly affects the normal use of the equipment. As a principle of selection, it is necessary to ensure that the mixer can fully perform its mixing function in the appropriate volume, which can generally be determined by the flow rate. According to the different process requirements of sewage treatment plants,Submersible thrusterThe flow rate should be ensured to be withinBetween 0.15~0.3m/s, if the flow velocity is lower than 0.15m/s, the push flow mixing effect cannot be achieved. If the flow velocity exceeds 0.3m/s, it will affect the process effect and cause waste. So before selecting, first determine the location where the low-speed thruster will be used, such as sewage tanks, sludge tanks, and biochemical tanks; Next are the parameters of the medium, such as suspended solids content, viscosity, temperature, and pH value; Also, the shape and depth of the pool.

The required matching power for the submersible mixing thruster is determined by the volume, density of the mixed liquid, and mixing depth, and one or more mixers are used according to the specific situation. As the quality of treated water approaches that of uncontaminated water, the practical benefits of water regeneration and reuse become very apparent.Submersible thrusterThe level of treatment and the quality of treated water make it economically valuable and a part of water resources. With the increasing application of advanced technologies such as activated carbon adsorption, advanced oxidation, and membrane technology in recycled water, the quality of recycled water has been able to meet or exceed traditional drinking water standards in all measurable indicators. Today, water regeneration or purification processes can technically provide almost all ideal water quality, including high-purity water for precision industry and medical use.

QJB4/4-1800/2-42/PLow-speed thrusterSuitable for stirring liquids containing suspended solids in sewage treatment plants and industrial processes, as well as aeration tanks in industrial and urban sewage treatment plants, which generate strong water flow with low tangential flow and can be used Create water flow during the cycling, nitrification, denitrification, and phosphorus removal stages.

The structure of low-speed thrusters is compact, small in size, and lightweight. The operation and maintenance are simple, the installation is convenient and fast, and the service life is long. The blades have self-cleaning function, which can prevent debris from entangling and blocking. When used in conjunction with the aeration system, it can greatly reduce energy consumption, significantly increase oxygen filling, and effectively prevent sedimentation. The motor winding of the low-speed thruster is insulated with Class F insulation and has a protection level of IP68. It uses imported bearings with one-time lubrication and maintenance free, and has oil chamber leakage detection and motor winding overheating protection functions, making the operation of the motor safer and more reliable.

The friction material of the low-speed propulsion equipment seal is corrosion-resistant tungsten carbide, and all fasteners are made of stainless steel. The diving depth can be adjusted vertically as needed, and the maximum angle that can rotate around the guide rod in the horizontal plane is ± 60 °. The lifting system base, support frame, and lower bracket are fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes. When the pool depth H is greater than 4 meters, it is recommended to use installation system II, which requires a concrete foundation to be built at the bottom of the pool.

The low-speed thruster lifting system base, steel rope fixing frame, and guide base are all fixed with expansion bolts at the associated interface with the pool, without the need for reserved holes.Low-speed thrusterInstallation systemReplacing guide rods with guide steel ropes has the advantages of convenient transportation and simple on-site installation. The low-speed thruster fundamentally avoids the situation of guide rod bending and deformation caused by transportation, which affects normal use, and effectively improves the phenomenon of inability to lift due to installation errors of guide rods when the pool is too deep.

The material of the low-speed thruster installation system is made of stainless steel (or carbon steel). In addition to the guide rod or guide wire, and the lifting base, multiple QJB submersible thrusters can share a set of lifting devices in the installation system. It can be widely used for anaerobic and facultative treatment of industrial wastewater and urban domestic sewage in industries such as petroleum, chemical, printing and dyeing, leather making, medicine, food, papermaking, textile, pesticide, etc.Low-speed thrusterUsing special materials for molding, the maximum impeller diameter reachesΦ2500， After optimization design, the blades have a swept back shape, high hydraulic efficiency, and self-cleaning function.
