Novel filter capable of measuring liquid flow rate and continuously working

Abstract

The invention relates to a novel filter capable of measuring liquid flow rate and continuously working, which comprises a surface body, a bottom plate, an inner core and an electromagnetic sensing annunciator. The inner core is a main structure part and consists of an impeller, a rotating shaft, a filtering screen and a scrapper. The surface body and the inner core form two channels to separate fluid from impurities. The fluid flows into the filtering screen from the bottom plate, flows out from the surrounding part, and flows by the impeller, and finally flows out from the top end of the surface body. The impeller is driven to rotate when the fluid flows by the impeller, and the rotation speed of the impeller and the fluid quantity have fixed quantity relation, the change of the flow rate can be displayed and the stability of the system can also be detected. Meanwhile, because the impeller is coaxial to the scrapper, the scrapper is driven to rotate to automatically clean impurities on the inner wall of the filtering screen; the impurities can also be cleared when the system runs so as to ensure the continuity of filtering operation. The invention also has functions of a flowmeter and a filter; and therefore, the filter has strong practicability.

Description

technical field [0001] The invention relates to a fluid filter, in particular to a novel filter capable of measuring liquid flow and working continuously. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, fixed water level valve or other equipment to eliminate impurities in the medium to protect the normal operation of the valve or equipment. use. At present, there are many types of filters on the market, but after working for a period of time, as the amount of impurities increases, these filters have to stop running to remove them for cleaning, or remove a certain part for cleaning, which affects the system. continuously working. Moreover, the existing filter usually adopts the method of installing a pressure gauge before and after the filter to detect the stability and resistance of the fluid before and after the filter, whic...

At present, there are many types of filters on the market, but after working for a period of time, as the amount of impurities increases, these filters have to stop running to remove them for cleaning, or remove a certain part for cleaning, which affects the system. continuously working

Moreover, the existing filters usually install a pressure gauge before and after the filter to detect the stability and resistance of the fluid before and after the filter, which leads to the structure of the filter being not simple enough.
