Description
Technical field
The present patent application belongs to fluid filtering device technical field, specifically discloses a kind of filter.
Background technique
Filter (filter) is indispensable a kind of device on pumped (conveying) medium pipeline, is typically mounted on pressure reducing valve, pressure release
Valve, Valve for keeping constant water level, the import end equipment of the square other equipment of work filter.Filter is by shell (cylinder), stainless steel filtering net, blowdown
Partially, transmission device and electrical control division are grouped as.Water or liquid to be processed is miscellaneous after the filter cylinder of strainer screen
Matter is blocked, and when needing to clean, as long as dismountable filter cylinder is taken out, is reloaded after processing, therefore, using extremely
It is convenient, at present filter have been widely used for petrochemical industry, petroleum gas, steel, metallurgy, papermaking, high-rise building,
The industries such as water conservancy.
But current filter, there are the following problems:
1. the excessively high particle of filtering accuracy is easy to reveal from the junction of filter core and shell.
2. can not determine a need for cleaning or replacing filter core.When periodic operation, it is found that it is serious stifled the filter core removed exists
Plug has influenced equipment normal operation.Or only slight blocking, normal use is not influenced, but lost labor dismounts cost and parking is set
Economic loss caused by standby.
3. under harsh conditions, the unapproachable operating condition scene of operator.
4. remote area, and the use site not enough concentrated using product, lead to that manual inspection cost is excessively high and there are one
Fix the number of workers's security risk.
It is used 5. the sheet oxide layer that the Anticorrosion of outdoor installation and filter core rear end fall off influences upstream device
Summary of the invention
The purpose of the present invention is to provide a kind of filters, to solve the above problems.
In order to achieve the above object, base case of the invention are as follows:
A kind of filter, including shell, the shell be equipped with inlet and liquid outlet, the shell include admission chamber and
Sap cavity out, the admission chamber are connected to inlet, and the sap cavity out is connected to liquid outlet, are set between the admission chamber and out sap cavity
There are the strainer for being installed on inner walls, the admission chamber and sap cavity to be out connected to by the filter mouth on strainer, is also set on the shell
There is the sewage draining exit for clearing up dirt, the bottom end of the strainer is connect with sewage draining exit；It is detachably connected on the sewage draining exit useful
In the lid of sealing；The admission chamber be equipped with preceding connecting pipe, it is described go out sap cavity be equipped with rear connecting pipe, the preceding connecting pipe and
Differential pressure information can be wirelessly transmitted to external differential pressure indicator by being connected between connecting pipe afterwards.
The working principle of this base case is:
Shell includes admission chamber and sap cavity, the admission chamber are connected to inlet out, and the sap cavity out is connected to liquid outlet,
Shell includes admission chamber and sap cavity, the admission chamber are connected to inlet out, and the sap cavity out is connected to liquid outlet.When need by
After the liquid of filtering enters admission chamber from inlet, these liquid can enter strainer, miscellaneous into the particle in the liquid of strainer
Matter etc. can be realized the purpose of filtering by strainer barrier；And the liquid after filtering enters sap cavity simultaneously by the filter mouth on strainer
And it is left from liquid outlet, and then complete complete filtering process.The sewage draining exit for clearing up dirt is additionally provided on shell, it is described
The bottom end of strainer is connect with sewage draining exit；The lid for sealing is removably connected on the sewage draining exit；The present apparatus works one section
After time, sundries can be accumulated in strainer, the particulate matter retained in strainer or impurity etc. can be taken out by opening lid at this time, can
To realize the purpose of cleaning and blowdown to strainer.The admission chamber is equipped with preceding connecting pipe, it is described go out after sap cavity is equipped with
Connecting pipe, differential pressure information can be wirelessly transmitted to external differential pressure indicator by being connected between the preceding connecting pipe and rear connecting pipe；It is logical
The inlet and outlet pressure that both ends connecting pipe is conveyed is crossed, the pressure difference numerical value is shown on differential pressure indicator, analyses whether to need to clean；Pressure
Difference is then represented greater than amount numerical value to need to clean.Installation can be with the differential pressure indicator of wireless remote function, the numerical value on this filter
Wirelessly the number can intuitively be monitored by being transported to cloud or user (or supplier) computer control room, external controlling unit
Value, to judge whether need to clean, avoids under harsh conditions, operating condition that operator can not be periodically into scene or
The use site that remote area is not enough concentrated using product, causes manual inspection cost excessively high and there are certain personnel safety wind
Danger.
Further, preceding connecting pipe is equipped with leading pressure ball valve, and the rear connecting pipe is equipped with rear pilot ball valve, convenient for control
When making, and simultaneously closing off leading pressure ball valve and rear pilot ball valve, differential pressure indicator can be replaced.
Further, the position that strainer is contacted with shell is equipped with the O-ring for preventing particulate matter to be lost, and can reduce and directly rub
It wipes, postpones service life, and can guarantee the leakproofness between filter core and shell, little particle was prevented to be lost from the gap.
Further, the lid is connect with casing bolts.
Further, it is equipped with gasket between the strainer and lid, increases leakproofness, prevents from revealing.
Further, the surface of shell Shot Blasting, the shell entirely through electrophoresis and phosphorating treatment, the shell
Surface be also coated with epoxy powder, improve the anti-corrosive properties of outdoor installation, avoid the sheet oxide layer that strainer falls off
Upstream device is influenced to use.
This programme beneficial effect includes:
1, it reduces and blindly tears filter number open, reduce machine stop times and economic loss；
2, manual inspection is reduced, business administration cost is reduced；
3, current behaviour in service also can be clearly received under harsh conditions；
4, the design disadvantage because of original filter is prevented, the damage of downstream product is caused.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention；
