The structural representation of the back-flushing filtering system that Fig. 2 provides for the embodiment of the present invention two.
Detailed description of the invention
As shown in Figure 1, the embodiment of the present invention provides a kind of back-flushing filtering system, comprises filter and is arranged on the back purge system on filter; Filter comprises primary flow pipe 1, is arranged on the first valve 10, filter 2 and the second valve 20 on primary flow pipe 1 in turn; Filter has water inlet 1a and delivery port 1b, and the first valve 10 is near water inlet 1a, and the second valve 20 is near delivery port 1b; Back purge system comprises tube connector 3, is connected to the 3rd valve 30 on tube connector 3 and is connected to filter 2 blowoff valve 4 between the first valve 10; Tube connector 3 one end are connected on primary flow pipe 1 and between water inlet 1a and the first valve 10, and tube connector 3 other ends are connected between filter 2 and the second valve 20.
Back-flushing filtering system provided by the invention, while filtering clear water, open filter, the first valve 10 and the second valve 20 are all opened, close back purge system, the 3rd valve 30 and blowoff valve 4 are all closed simultaneously, and water enters primary flow pipe 1 through water inlet 1a, successively through the first valve 10, filter 2 and the second valve 20, supply clean water finally by delivery port 1b to each water pipe again, in the time that filter core obstruction need to be cleared up, opening back purge system is that the 3rd valve 30 and blowoff valve 4 are all opened, close filter is that the first valve 10 and the second valve 20 are all closed simultaneously, water enters primary flow pipe 1 through water inlet 1a, again successively through tube connector 3 and the 3rd valve 30, oppositely enter filter 2, the impurity back flush being blocked on filter core is fallen, discharge impurity finally by blowoff valve 4, do not need more renew cartridge, therefore also needn't cut off equipment and dismantle primary flow pipe and filter, without because of frequently renew cartridge more of obstruction, reduce cost, and greatly reduce the dismounting of equipment pipe, use manpower and material resources sparingly, and greatly improve the operation ratio of equipment.Need a large amount of clean waters filtering by essence for fully-mechanized mining working support apparatus, emulsification pumping plant, cooling system and spray dust-reducing system in prior art, and in filter process, how to accomplish the problem that the impurity filtering out is recoiled away, the present invention proposes a kind of brand-new back-flushing filtering system, realized the filtration and the backwash that complete simply, easily clear water.
In above-described embodiment, filter 2 comprises housing 21 and is arranged on the filter core 22 in housing 21; Housing 21 one end are connected with the first valve 10, and housing 21 other ends are connected with the second valve 20; Tube connector 3 and blowoff valve 4 are all connected on housing 21, and tube connector 3 and blowoff valve 4 lay respectively at filter core 22 two ends.While filtering clear water, current filter backward each water pipe through the filter core 22 of housing 21 inside clean clear water are provided; When backwashing filter core, current oppositely can rinse out the impurity being blocked on filter core 22 through the filter core 22 of enclosure interior; Between the first valve 10 and filter 2, be all directly connected between filter and the second valve 20, in the time adopting above-mentioned syndeton, tube connector 3 and blowoff valve 4 are all connected on housing 21, reduce the volume of filter and back purge system and taken up room, be conducive to the centralized arrangement of back-flushing filtering system, and saving takes up room.
As the optimal way of above-described embodiment, for convenience of operation, the first valve 10 is gate valve.The second valve 20, the 3rd valve 30 and/or blowoff valve 4 are stop valve.In the present embodiment, the second valve 20, the 3rd valve 30 and blowoff valve 4 are stop valve.
As shown in Figure 2, in order to simplify filter apparatus configuration, reducing it takes up room, by be connected to the primary flow pipe 1 between the first valve 10 and filter 2 and be connected to filter 2 and the second valve 20 between primary flow pipe 1 all save, filter 2 one end are directly connected with the first valve 10, filter 2 other ends are directly connected with the second valve, further, for convenience of the installation of tube connector 3 and the 3rd valve 30, the delivery port that the 3rd valve 30 one end is connected to tube connector 3, the 3rd valve 30 other ends are connected with housing 21.
When use, after working face clear water pipe is disconnected, be connected on the flange of primary flow pipe of the present invention 1 water inlet, then be that the second valve 20 is connected on working face equipment by the stop valve of water outlet of the present invention.When normal work, backwash stop valve and the 3rd valve 30 are that blowoff valve 4 cuts out respectively with sewage globe valve, then opening gate valve is the stop valve of the first valve 10 and water outlet, and clear water is just by filter core 22, and the clean water after filter element filtering is supplied with working face equipment.
Supply water after a period of time, the impurity filtering out on filter core 22 will stop up filter core 22.Now, gate valve and delivery port stop valve are closed, open backwash stop valve and sewage globe valve simultaneously.Water in fresh water pipeline will be by tube connector 3 to the interior water supply of housing 21, utilize the pressure of clear water self, impurity in filter core 22 is gone out by the sewage draining exit backwash of sewage globe valve bottom, and all pipe joints, flange and stop valve must meet pressure requirement.Backwash end-of-job, recovers above step, continues to supply water to working face.
The present invention is simple and reasonable for structure, compact, easy to operate; Filtration is simple with the process of backwash, only needs a few minutes can complete the backwash of filter core 22, has greatly reduced workload, has reduced cost; Also avoid because filter core frequently stops up, the normal operation of equipment being affected greatly simultaneously, reduced equipment failure rate, improved mine production efficiency; Simultaneously simple in structure, easy access and replacing.
Finally it should be noted that: above each embodiment, only in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
