Abstract

The utility model discloses a fluid filter, which comprises a body with a filter cavity. A filter element is arranged in the filter cavity, and divides the filter cavity into an inner cavity and an outer cavity. An inlet pipe and an outlet pipe are arranged on the body, and are opposite to each other. The inlet pipe is communicated with the inner cavity, and the outlet pipe is communicated with the outer cavity. A pressure gauge is connected between the inlet pipe and the outlet pipe through an oil-pressure pipe. An upper cover is detachably connected to the top of the filter cavity. A sewage draining outlet is formed in the bottom of the filter cavity, and is communicated with the inner cavity of the filter cavity. The pressure gauge is arranged between the inlet pipe and the outlet pipe, and the clogging condition of the filter element can be visually judged by observing a digital value of the pressure gauge, so that the filter is not required to be regularly disassembled to clean the filter element. In addition, the upper cover is detachably connected to the top of the filter cavity, so that the filter element can be cleaned only by opening the upper cover without disassembling the whole filter. Moreover, part of impurities in the filter cavity can be drained from the sewage draining outlet, so that the filter element cleaning cycle can be prolonged.

Description

A kind of fluid filter

Technical field

The utility model relates to a kind of filter, is used for the fluid filter that liquid or gas are filtered specifically.

Background technology

Fields such as chemical industry, medical medicine, oil, natural gas, metallurgy, weaving and food extensively adopt filter that liquid or gas medium are filtered in the fluid of its use, guarantee the security that terminal device uses.As the obstruction that can avoid the nozzle of burner behind the filter is set in fuel passage; The basic structure of existing fluid filter comprises a body with import and outlet; In body, be provided with filter core, fluid gets in the filter body from import, behind filter element filtering, flows out from outlet; The impurity that contains in the fluid is adsorbed on the filter core; Existing fluid filter be owing to can't directly know the stopping state of filter core, so after using the regular hour, need remove just that filter cleans filter core or direct renew cartridge more.Because the impurity content in the fluid changes; Be generally the set time and filter core cleaned or change, the impurity content in certain section time fluid more for a long time, before the filter core to filter cleans or changes; The filter core of filter has stopped up seriously, and influence is normally used.Simultaneously, when the impurity content of certain section time fluid more after a little while, in the time needn't removing filter filter core is cleaned or changes, operating personnel also can regularly remove filter, cause unnecessary waste.Simultaneously, existing fluid filter needs to remove filter from pipeline when filter core is cleaned or changes, and operation is inconvenience very.

The utility model content

For overcoming above-mentioned defective, the utility model aims to provide a kind of can the monitoring the stopping state of filter core in real time, simultaneously, can easily remove filter core so that the fluid filter that filter core is cleaned or changes from filter body again.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of fluid filter comprises a body with filter chamber; Said filter chamber is built-in with filter core; Said filter core is divided into inner chamber and exocoel to filter chamber, has relative inlet pipe of position and one on the said body and goes out pipe, said inlet pipe and intracavity inter-connection; Saidly go out pipe and be connected with exocoel, said inlet pipe and go out to manage between be connected with a Pressure gauge through oil pressure pipe.

The top of said filter chamber is removably connected with a loam cake.

The bottom of said filter chamber is provided with sewage draining exit, the intracavity inter-connection of said sewage draining exit and filter chamber.

Adopted the fluid filter of the utility model and since inlet pipe with go out between the pipe to be provided with Pressure gauge, can real-time monitored to inlet pipe and the pressure differential between going out to manage; Thereby can judge the stopping state of filter core intuitively; Clear up filter core and needn't regularly remove filter, simultaneously, detachable loam cake is set through top at filter chamber; When need cleaning filter core, only loam cake need be opened, and whole filter needn't be removed; In addition, a part of impurity in the filter chamber also can be discharged through sewage draining exit, can prolong the cycle of cleaning filter core.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure: the 1-body, the 2-filter chamber, the 3-filter core, the 4-inlet pipe, 5-goes out pipe, 6-inner chamber, 7-exocoel, 8-oil pressure pipe, 9-Pressure gauge, 10-loam cake, 11-sewage draining exit.

The specific embodiment

As shown in Figure 1, the utility model discloses a kind of fluid filter, comprise a body 1 with filter chamber 2; Said filter chamber 2 is built-in with filter core 3, and said filter core 3 is divided into inner chamber 6 and exocoel 7 to filter chamber 2, and promptly the inwall of filter core 3 surrounds an inner chamber 6; The inwall of the outer wall of filter core 3 and filter chamber 2 surrounds an exocoel 7, has relative inlet pipe 4 of position and one on the said body 1 and goes out pipe 5, and said inlet pipe 4 is connected with inner chamber 6; Saidly go out pipe 5 and be connected with exocoel 7, fluid gets into the inner chamber 6 of filters, entering exocoel 7 after the filtration of filter core 3 through inlet pipe 4; After being filtered by filter core 3, the impurity that contains in the fluid stayed inner chamber 6 or attached on the filter core 3; Thereby realized the filter cleaning process of convection cell, in sum, with the version basically identical of existing fluid filter.

The innovative point of the fluid filter of the utility model mainly is said inlet pipe 4 and goes out between the pipe 5 to be connected with a Pressure gauge 9 through oil pressure pipe 8.Two ends of oil pressure pipe 8 respectively with inlet pipe 4 with go out pipe 5 and be connected; Pressure gauge 9 can be read the fluid and the pressure differential that goes out the fluid in the pipe 5 in the inlet pipe 4; Because inlet pipe 4 is connected with inner chamber 6; Go out pipe 5 and be connected, so the numerical value that Pressure gauge 9 reads is exactly the pressure differential of inner chamber 6 and exocoel 7 in fact with exocoel 7.

When the filtering flow initial stage; Less relatively attached to the impurity on the filter core 3, the inner chamber 6 of filter is less with the pressure differential of exocoel 7, when filtering flow arrives the long time; Or the impurity that fluid contains more for a long time; Impurity can stop up filter core 3, makes fluid pass through the ability drop of filter core 3, thereby causes the inner chamber 6 and the pressure differential of exocoel 7 to become big.Therefore, operating personnel only need be through the numerical value of monitoring pressure table 9, and just can judge whether needs filter core 3 is cleared up or changed.

For the cleaning that makes filter core 3 or change conveniently, the top of said filter chamber 2 is removably connected with a loam cake 10.When filter core 3 need be cleared up or change, only need open loam cake 10, can conveniently take out filter core 3 and clear up or change.

For cleaning in time is deposited on the impurity in the inner chamber 6, the bottom of the said filter chamber 2 of the fluid filter of the utility model is provided with sewage draining exit 11, and said sewage draining exit 11 is connected with the inner chamber 6 of filter chamber 2.Operating personnel can discharge the impurity that is deposited in the inner chamber 6 through time opening sewage draining exit 11, thereby prolong the cycle that filter core 3 is cleared up or changed.
