Abstract
The utility model discloses a line internal backwashing filtering system, comprising a raw material inlet pipe and a raw material outlet pipe. A differential pressure detection instrument and a plurality of filters arranged in parallel are arranged between the raw material inlet pipe and the raw material outlet pipe; a raw material inlet is arranged at one end of the raw material inlet pipe; a raw material outlet is arranged at one end of the raw material outlet pipe; a normally-open control valve is arranged at the joint segment of each filter and the raw material inlet pipe; the raw material inlet pipe is provided with a backwashing drain outlet; a normally-closed control valve is arranged at the joint of the raw material inlet pipe and the backwashing drainage outlet; and a normally-open control valve is arranged at the joint of the raw material inlet pipe and the raw material inlet. The utility model has the advantages of compact structure, reasonable design, and the like.
Description
Technical field
The utility model relates to a kind of filtration system, specifically is meant backwash filter system in a kind of in-line arrangement.
Background technology
Automatic backwashing filter is a kind of advanced person, efficient and easy-operating automatic filtering apparatus, is widely used in metallurgy, chemical industry, oil, papermaking, medicine, food, mining, electric power, city water field.Such as the filtration of feedstock oil, industrial wastewater, recirculated water in the petroleum refining, the regeneration of emulsion, the waste oil waste water filtering is handled, the continuous casting water system of metallurgy industry, blast furnace water system, hot rolling high-pressure water descaling system.With the medium is that water is example, and its operation principle is that water is intake into filter by import, and after the process filter cartridge assembly filtered mechanical admixture, clear water was discharged by delivery port.In filter process, the impurity on the filter core is piled up gradually, and its inside and outside both sides have just formed a pressure reduction.When this pressure reduction reaches preset value, undertaken filter is cleaned one by one automatically by the program of setting, the waste liquid after the cleaning is discharged by blowoff valve, and filter continues to filter then, and begins to prepare next flushing cycle.In cleaning process, it is uninterrupted that filter filters work normally.
Its shortcoming of backwash filter system is in the in-line arrangement that the automatic backwashing filter that a plurality of arrays of existing application are arranged is formed: independently be provided with the sewage backwash pipe, and all need to be provided with by-pass valve control between each automatic backwashing filter and the sewage backwash pipeline, cause whole system valve quantity many, volume is bigger, and structure is compact inadequately.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provides a kind of compact conformation, backwash filter system in the in-line arrangement reasonable in design.
For achieving the above object, technical scheme of the present invention is to include raw material inlet pipe and raw material to go out pipe, described raw material inlet pipe and raw material go out to be provided with between the pipe pressure differential detection instrument and a plurality of filter that is arranged side by side, one end of described raw material inlet pipe is provided with the feed(raw material)inlet, the end that described raw material goes out pipe is provided with material outlet, it is characterized in that: the junction of described each filter and raw material inlet pipe is provided with the open type control valve, described raw material inlet pipe is provided with the sewage backwash mouth with respect to the other end of feed(raw material)inlet, this raw material inlet pipe is provided with the closed type control valve with respect to the inboard of sewage backwash mouth, and this raw material inlet pipe is provided with the open type control valve with respect to the inboard of feed(raw material)inlet.By this setting, only need the raw material inlet pipe be provided with a closed type control valve and can realize sewage backwash, compared to background technology, not only need not the sewage backwash pipe is set in addition, and valve quantity also greatly reduces, compact overall structure is reasonable.
Further be provided with is that described raw material inlet pipe and raw material go out Guan Jun many covers are arranged, and every cover raw material inlet pipe and raw material go out to be provided with a plurality of filters that are arranged side by side between the pipe, described feed(raw material)inlet is communicated with an end of the raw material inlet pipe of many covers respectively, described sewage backwash mouth is communicated with the other end of the raw material inlet pipe of many covers respectively, and described material outlet is communicated with the end that many covers raw material goes out pipe respectively.By this setting, can realize that many cover systems work simultaneously, increase work efficiency.
This be provided with specifically can described raw material inlet pipe and raw material go out Guan Jun two covers arranged.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model specific embodiment principle schematic;
Fig. 2 the utility model specific embodiment is overlapped filtration system operation principle schematic diagram simultaneously more.
The specific embodiment
The specific embodiment of the present utility model as shown in Figure 1, include raw material inlet pipe 1 and raw material and go out pipe 2, described raw material inlet pipe and raw material go out to be provided with between the pipe pressure differential detection instrument 3 and a plurality of filter that is arranged side by side 4, one end of described raw material inlet pipe 1 is provided with feed(raw material)inlet 11, the end that described raw material goes out pipe 2 is provided with material outlet 21, linkage section 41 places of described each filter 4 and raw material inlet pipe 1 are provided with open type control valve 411, this open type control valve 411 is at native system and is open mode under the normal filtration state, and switch to closure state during backwash, its completion status is switched can carry out programming Control according to programme-control or PLC module, described raw material inlet pipe 1 is provided with sewage backwash mouth 12, this raw material inlet pipe 1 is provided with closed type control valve 121 with sewage backwash mouth 12 junctions, this closed type control valve 121 is under the normal filtration duty for closed at native system, and when pressure differential detection instrument 3 surpasses setting value, automatically switch to open mode, this raw material inlet pipe 1 is provided with open type control valve 111 with respect to the inboard of feed(raw material)inlet 11, native system is under the normal filtration duty for opening, and when pressure differential detection instrument 3 surpasses setting value, automatically switch to closed condition.The utility model, only need be provided with closed type control valve 121 and can realize sewage backwash,, not only need not to be provided with in addition the sewage backwash pipe compared to background technology in raw material inlet pipe 1 and sewage backwash mouth 12 junctions, and the also greatly minimizing of valve quantity, compact overall structure is reasonable.
In addition, in order to increase work efficiency, realize how the cover filtration systems are worked (as shown in Figure 2) simultaneously, described raw material inlet pipe 1 and raw material go out pipe 2 all many covers, and every cover raw material inlet pipe 1 and raw material go out between the pipe 2 to be provided with a plurality of filters that are arranged side by side 4, described feed(raw material)inlet 11 is communicated with an end of the raw material inlet pipe 1 of many covers respectively, described sewage backwash mouth 12 is communicated with the other end of the raw material inlet pipe 1 of many covers respectively, and described material outlet 21 is communicated with the end that two cover raw materials go out pipe 2 respectively.
