When the solution needs to be filtered, put a water-based filter membrane on the filter head to fix the stainless steel filter cup and the filter head through a clamp. The air nozzle is connected with the vacuum power, and the disc valves of the stainless steel solution filter are opened to inject the solution into the filter. Cup, turn on the vacuum power, the solution passes through the filter membrane on the filter head. Under the dynamic action, the solution quickly flows into the collection chamber through the filter holder. After all the solution in the filter cup flows into the collection chamber, you only need to remove the filter membrane to be analyzed. . The filter hole will become smaller and smaller, which creates a pressure difference between the inlet and the outlet. When the large difference reaches the set value, the control system of the stainless steel solution filter starts the drive motor to drive the shaft to rotate through the transmission assembly, and at the same time the sewage outlet Open and discharge from the drain. When the filter screen is cleaned, the pressure difference drops to a small value, the system returns to the initial filtering state, and the system runs normally. The filter consists of a housing, a multi-element filter element, a backwash mechanism, and a differential pressure controller. And other parts of the composition.
The horizontal partition in the housing of the stainless steel solution filter divides its inner cavity into upper and lower cavities, and the upper cavity is equipped with multiple filter elements, which sufficient filtration space and significantly reduces the volume of the filter. A backwash suction cup is installed. At the same time, the glass material is fragile and not easy to be sterilized by high temperature. The purpose of the stainless steel solution filter is to filter multiple samples at the same time to improve the efficiency of the experiment. The large-caliber, large-capacity liquid storage bottle is very easy to clean; equipped with a bottle stopper with a sealing ring, it has good sealing and opening Convenience. The responsive and reliable overflow protection device can prevent liquid from entering the intermediate pipe. The stainless steel solution filter adopts a transparent PVC suction hose to facilitate the observation of the liquid in the pipe during suction; the unique pipe joint design makes the pipe connection more convenient. The negative pressure regulating valve can control the negative pressure required for suction, and the negative pressure value is displayed by the vacuum gauge.
