Fully automatic cleaning microfiltration machine, factory aquaculture equipment, drum microfiltration machine

.r The second-generation automatic backwash drum microfiltration machine is the latest microfiltration machine upgraded on the basis of the first-generation drum microfiltration machine of Lanling Aquarium. It is also called a drum filter. It not only improves all the advantages of the first-generation drum microfiltration machine but also makes targeted improvements based on feedback from a large number of customers. Making its various performance indicators almost perfect.
. Equipment structure and basic principles
.r The microfilter uses a rotatable stainless steel drum to filter. The outside of the drum has a dense stainless steel screen. The drum can be driven by an electric motor via gears. There is a pressurized water pump composed of a plastic pump shell outside the microfiltration machine box. A pressurized water pump is connected to an array of plastic nozzles. There are two water level controllers inside the box that can transmit signals to the control electrical box according to water level changes. The control center in the electrical box will effectively control related equipment. There is a larger-diameter water inlet, a smaller-diameter drain outlet, and a sewage pipe on the box. Drainage adopts the method of rear-mounted water pump. All automatic devices of the microfiltration machine are controlled by the control electric box outside the microfiltration machine box.
.Usage
The microfilter should be placed at the same level as the water surface to be treated. The sewage flows into the drum of the microfiltration machine by itself. After the drainage pump is started, the water level outside the drum will drop and water will flow from the inside of the drum to the outside. Dirt in the water is intercepted by the stainless steel screen. After running for a period of time, more and more dirt is intercepted by the stainless steel screen, which creates an increasing resistance to the water flow. However, the drainage flow rate has not decreased due to the stable operation of the water pump, so the water level outside the drum continues to decrease. When the water level drops to the location of the water level controller, the water level controller will transmit an electrical signal to the control center. The control center will start the drum motor and pressurized water pump. The drum starts to rotate slowly and at the same time, the high-pressure water pump pumps high-pressure water from the nozzle to flush away the dirt adhered to the screen. The dirt is collected in the sewage collection tank inside the drum and then discharged from the sewage pipe. Complete the process of solid-liquid separation.

When the dirt inside the drum is flushed, the water level inside and outside the drum remains level with the rotation of the drum. The microfiltration machine enters the next cycle.
.Instructions for use
.The filtration process is still maintained while the microfilter is backwashed. And the drum does not rotate when not backwashing. Therefore, the actual power consumption of the microfiltration machine is very small.
.In addition, the upper edge of the microfilter box is higher than the water surface of the water to be treated, so there is no need to worry about the water overflowing the microfilter
.When the water level is lower than the warning water level, the control center of the microfilter It will sound an alarm and shut down the drain pump to prevent the drain pump from being damaged due to idling.
.When a short circuit or other fault occurs in the circuit of the microfiltration machine, the leakage switch in the control center will automatically stop power supply.

. -d <-r . The second-generation microfiltration machine uses a truly custom-made stainless steel screen that can withstand excessive liquid environments for a long time without rusting. And a special weaving method is used to greatly increase the strength of the screen to prevent the screen from being easily broken. The cross-section of the screen is as shown below:
. The drum driving method is changed from the central shaft drive to the drum external gear driving torque, which greatly reduces the power consumption and is almost negligible. Moreover, the small torque can also greatly reduce the probability of failure of the drum central axis. At the same time, the drum rotates slower during backwashing and the screen is washed cleaner.
.Both the drum and the screen adopt a very convenient detachable design. The drum adopts the form of external flange to make the drum easier to repair, replace or clean.
.The roller adopts a double-bearing design, so that the rotational torque of the roller is extremely small when it rotates, and the force is very uniform everywhere, which will not cause uneven wear of the sealing rubber skin.
.The latest internal and external sealing design of the drum perfectly isolates sewage and clean water without causing rapid wear of the rubber seals. At the same time, Lanling Aquarium will provide customers with an extra set of rubber skins as spare parts.
.Parts in contact with water are made of corrosion-resistant materials. The box body is made of food-grade plastic. The main body of the roller is made of food-grade material. The screen is made of real stainless steel. The sealing rubber is made of wear-resistant high-grade sulfur rubber. The screws are all made of pure titanium screws.
.The water outlet pipe is connected to the water pump, that is, the rear-mounted design of the water pump allows the microfilter to have a larger effective filtration area during filtration, thereby reducing the frequency of backwashing. At the same time, the post-positioning of the water pump allows subsequent equipment to directly use the outlet water pump of the microfiltration machine as the power source, reducing the number of water pumps in the entire system.
.Backwash control includes water level control, timing control, time interval control, manual control and many other methods to choose from.
.The water level controller is a non-contact electromagnetic water level controller, which can effectively prevent the contact water level controller from malfunctioning due to seawater corrosion or foreign matter entry.
.The control electrical box is composed of imported electrical components. The control circuit voltage is no higher than multi-level weak current control to ensure the reliability of the control system. The bottom water level controller can cause the control center to alarm and the outlet water pump to cut off power in time to prevent idling.
