Introduction to the internal structure of stainless steel vacuum filtrations
When solution filtration is required, a water filter is placed on the filter head to fix the stainless steel filter bowl and the filter head through the clamp, the gas nozzle is connected with the vacuum power, the various disc valves of the stainless steel vacuum filtrations are opened, and the solution is injected into the filter. The cup, open the vacuum power, the solution passes through the filter on the filter head under the action of power, the solution quickly flows into the liquid collection chamber through the filter holder, and the solution in the filter bowl flows into the liquid collection chamber, and only the filter to be analyzed can be removed. The filter hole will become smaller and smaller, thereby creating a pressure difference between the inlet and the outlet. When the degree difference reaches the set value, the control system of the stainless steel vacuum filtrations starts the drive motor to drive the shaft to rotate through the transmission assembly, and the sewage outlet open, discharged from the sewage outlet. When the filter is cleaned, the pressure difference is reduced to a minimum value, the system returns to the initial filtration state, the system operates normally, and the filter consists of a casing, a multi-filter, a backwashing mechanism, and a differential pressure controller. Part of the composition.
The diaphragm in the stainless steel vacuum filtrations housing divides the inner cavity into upper and lower chambers, and the upper chamber is provided with a plurality of filter cores, so that the filtering space is fully reduced, the volume of the filter is significantly reduced, and the inner cavity is narrowed. A backwash suction cup is installed. At the same time, the glass material is fragile and difficult to be disinfected at high temperature The purpose of the stainless steel vacuum filtrations is to filter multiple samples at the same time, improve the experimental work efficiency, large diameter, large capacity liquid storage bottle, easy to clean; with a stopper with a sealing ring, good sealing and opening Convenience. The reaction-sensitive and reliable overflow protection device prevents liquid from entering the intermediate pipe. The stainless steel vacuum filtrations use a transparent PVC suction hose to facilitate the observation of the liquid in the pipe when it is attracted. The unique pipe joint design makes the pipe connection more convenient. The negative pressure regulating valve controls the negative pressure required for suction, and the negative pressure value is displayed by a vacuum gauge.
