Vertical circulating mixer, gentle and uniform mixing equipment

Vertical circulating mixer, gentle and uniform mixing equipmentProduct Overview:

P/LHJA vertical circulating mixer, also known as a float type submersible mixer, is a mixing equipment designed for deep circular or square tanks that require gentle and uniform mixing without damaging the flocculent structure and bacterial flocs of activated sludge. On the basis of summarizing the existing sewage mixing equipment, the product structure and performance have been improved, especially on the basis of the push type mixer. The horizontal structure has been changed to a vertical circulation structure, which improves its overall structural technical performance, mixing efficiency, service area, applicability, etc. It has the advantages of long service life, low noise, easy installation and maintenance, low investment, and low operating costs.

Vertical circulating mixer, gentle and uniform mixing equipmentworking mechanism:

LHJThe vertical circulating mixer adopts a large displacement, propeller type propulsion impeller and blade as the main hydraulic components. During operation, the submersible motor drives the propulsion impeller and blade to work, generating a certain flow velocity and field of fluid, forming a circular main flow belt towards the bottom and surroundings of the pool. Due to the high flow velocity of the main stream, a turbulent area centered around it is formed, which promotes the formation of a large circulation of up and down flipping in the entire water body, thereby achieving large-scale three-dimensional circulation agitation, keeping the sludge in the tank in a constantly flipping and suspended state, achieving the goal of uniform and gentle agitation, and improving the treatment effect.

PHJThe float type submersible mixer is divided into three mixing series: high, medium, and low, depending on the usage scenario:

The medium to high speed mixing series has a relatively high rotational speed and a relatively small service range, but the mixing is relatively gentle. Suitable for anaerobic or facultative treatment of wastewater.

The low-speed push mixing series has low rotational speed, wide service range, high hydraulic efficiency, and uniform mixing. It can be used in regulating tanks of various sewage treatment projects, as well as for anaerobic or facultative treatment.

Product Features:

1. The turbulent flow area is large, the action area is wide, the stirring is gentle and uniform, and it will not have a destructive effect on the flocculent structure and microbial flocs of activated sludge.

2. The water flow adopts a vertical large circulation flow scheme, suitable for deeper circular or square water tanks, with sufficient mixing of sludge and a radiation area of up to100~800square meter.

The power of the mixer is a submersible motor, which works underwater during application. It not only has good cooling conditions and a wide range of applicable depths, but also does not produce secondary pollution such as noise.

The main seal of the submersible motor is two mechanical seals, and the friction material is corrosion-resistant and wear-resistant alloy and silicon carbide. All fasteners are made of stainless steel material.

5. The motor winding isFGrade insulation, protection level isIP68，Configure leak detection, winding overheating and other protection functions to make product use more stable

⒍ Multiple installation styles can be adopted. When using floating installation, the working position can be moved at any time, which is convenient and flexible; It can be controlled centrally and automatically, or run independently, making management convenient.

Scope and conditions of application:

It can be widely used for the treatment of wastewater and urban domestic sewage in industries such as petroleum, chemical, printing and dyeing, leather making, medicine, food, papermaking, textile, pesticide, etc.

medium temperature~0℃-40℃

mediumPHvalue~5-9

The medium density does not exceed1150Kg/m3；

The equipment is limited by fiber materials, so it is necessary to avoid debris such as plastic woven fabrics, metal wires, and wooden sticks from entering the pool.

Submersible motors mustWork underwater and avoid working in environments that are flammable, explosive, or highly corrosive.

Installation and debugging:

Installation of medium and high-speed mixers

⑴. Tighten the four float hoops to the middle positions of the four sides of the float box, and then connect one end of the fixed steel wire rope to the earring on the hoops with a shackle. During installation, four sufficiently long and sturdy ropes should be prepared according to the site conditions, and the other end of the steel wire rope should be securely fastened.

⑵. The cable of the submersible mixer should be fixed on a steel wire rope and extended to the shore to connect to the electrical control cabinet.

⑶. Check the rotation direction of the motor. Before the initial installation and start-up of the submersible mixer, or after each reinstallation, the rotation direction should be checked. The inspection method is to instantly start the submersible mixer and observe that the rotation direction of the impeller is consistent with the direction indicated on the label. If the rotation direction is not consistent, simply exchange the positions of any two phase lines in the three phases. If multiple submersible mixers are connected to the same control box or terminal, each submersible mixer must be inspected separately.

⑷. Secure the float with a lifting device and pay attention to balance. Do not hang it directly on the hoop earrings. Use a lifting device to slowly lift the entire machine and slowly place it into the pool water. Unscrew the lifting device and gently pull it to the position in the pool with a fly rope. Place the float in a diamond shape with four corners facing the edges of the pool. Then slightly tighten the steel wire rope and visually observe that the two steel wire ropes on the opposite side are in a straight line. The two straight lines formed by the four steel wire ropes intersect vertically and are perpendicular to the four sides of the float. Drill a hole in a sturdy position at the upper end of the pool wall along the direction of the steel wire rope, fix the ground pile with expansion bolts, adjust the length of the four steel wire ropes, pay attention to the possible drop in water level, release enough allowance, clamp the clamp, and fix it to the ground pile with a shackle. During the entire lifting process, always pay attention to protecting the cables and never allow the use of submersible mixer cables to lift or suspend the mixer.

Installation of low-speed mixer

When installing the blade slurry, install it according to the matching surface between the hub and the blade slurry, and the sharp angle of the blade slurry must exceed the main engine hub. the restInstallation stepsandThe installation steps for medium and high-speed mixers are consistent.

Attention! The impeller cannot be reversed underwater, otherwise it will cause serious damage to the main engine and blades!
