Fluid heat insulation filtering apparatus

Abstract

The invention relates to a fluid filtering apparatus, in particular to a filter which can be simultaneously applied to gas and liquid and adopts a vacuum tank structure. The product only consists of nine parts, i.e. an outer tightening screw ring, a tightening gasket, an anti-leakage gasket, an inner tightening screw ring, a supporting tray, a rear sponge support, an activated carbon section, a front sponge cap and a suction filtering head, comprises twenty composition parts, i.e. an antiskid rhombus groove, a tightening ring wall, a tightening top surface, an internal screw thread, a straight line screw groove, an external screw thread, a tightening top surface, a support ring, a supporting surface, a filtering through hole, a bottom surface, an outer ring wall, an outer ring bottom surface, a filtering casing, a suction hole, a filtering casing inner cavity, an inner ring wall, a vacuum tank and the like, has the characteristics of vacuum heat insulation, reliability for using, simpleness and convenience for maintenance, wide adaptability and the like and can be widely suitable for the requirements for filtering, adsorption, purification and impurity removal of domestic water and industrial water. Moreover, the product disclosed by the invention is simple to implement, is easy to manufacture, has wide market space and has a certain social application value and economic added value.

Description

technical field [0001] The invention relates to a fluid filtering device, in particular to a filter which can be applied to both gas and liquid and adopts a vacuum groove structure. Background technique [0002] Fluid filter refers to a physical device that can selectively filter particles of a certain size in a flowing object (such as gas, fluid), and is usually installed on a pressure reducing valve, pressure relief valve, fixed water level valve or other equipment. The inlet end is used to eliminate impurities in the medium to protect the normal use of valves and equipment. When the fluid enters the filter cartridge with a filter screen of a certain specification, its impurities are blocked, and the clean filtrate is discharged from the filter outlet. [0003] Fluid filter is an indispensable device on the conveying medium pipeline. Currently known fluid filtering devices include screens, gauzes, screens, fishing nets, masks, protective covers, etc. Although these fluid...

Problems solved by technology

Currently known fluid filtering devices include screens, gauzes, screens, fishing nets, masks, protective covers, etc. Although these fluid filtering devices have been developed to the present, they have made great progress in function, can go deep into the ocean, can filter To remove tiny particles as small as a few millimeters, but there is still a common defect, namely: the fluid filtered by these devices still maintains a cold and heat exchange mechanism with the outside world, and its temperature still changes with the rise and fall of the outside temperature And corresponding changes take place, thereby affecting the scope of application, social use value and economic added value of these known fluid filtering devices
