Description

Middle water inlet back purge system
Technical field
The utility model relates to purified treatment field, especially relates to a kind of middle water inlet back purge system.
Background technology
Along with the fast development of national economy, the quick growth of population and the raising of living standards of the people, domestic water and industrial water consumption are all in continuous increasing, and tellurian water resource is limited after all, in order to relax the contradiction between limited water source and the water consumption that continues to increase, in recent years, the exploitation of rainwater resource is more and more subject to people's attention.The exploitation of rainwater resource are using water wisely, reduce Urban Flood Waterlogging, alleviate drainage pipeline burden, improve the effective measures of water environment state, but rainwater directly can not use, after having to pass through dmp filter purification, industry or agricultural could be used for, rainwater is stayed in rain water filtering device through rain water filtering device filtered impurities, be difficult to discharge, manually impurity must could be removed, waste time and energy.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of middle water inlet back purge system, and can purify by auto-flushing, developing result is good.
The utility model solves the technical scheme that its technical problem adopts: water inlet back purge system in the middle of a kind of, comprise lid, body and chassis, lid top is provided with the first water inlet, and sidewall is provided with the second water inlet, tray bottom is provided with sewage draining exit, be provided with some filter cores in body, be provided with gap between filter core and body housing, filter core comprises inner filter core and outer filter core, inner filter core is fixed inner sleeve by inner filter core and is fixed, and outer filter core is fixed by retainer plate.
In a preferred embodiment of the present utility model, body is cylindrical, and lid and chassis are all the circles with this mates.
In a preferred embodiment of the present utility model, bottom outer filter core and inner filter core, be provided with filter core firm banking.
In a preferred embodiment of the present utility model, outer filter core is supported by screen support rod.
The beneficial effects of the utility model are: after adopting said structure, structure is simple, round and smooth circular body design makes impurity easily rinse, not easily remain, ensure that the quality of flushing, the external filter core of screen support rod realizes reinforcing and supports simultaneously, makes outer filter core stand larger water impact, extends the service life of filter core.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, lid; 2, body; 3, chassis; 4, the first water inlet; 5, the second water inlet; 6, sewage draining exit; 7, gap; 8, inner filter core; 9, outer filter core; 10, inner filter core fixed cover; 11, body housing; 12, retainer plate; 13, firm banking; 14, screen support rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
A kind of middle water inlet back purge system as shown in Figure 1, comprise lid 1, body 2 and chassis 3, lid 1 top is provided with the first water inlet 4, and sidewall is provided with the second water inlet 5, sewage draining exit 6 is provided with bottom chassis 3, be provided with some filter cores in body 2, be provided with gap 7 between filter core and body housing 11, filter core comprises inner filter core 8 and outer filter core 9, inner filter core 8 is fixed inner sleeve 10 by inner filter core and is fixed, and outer filter core 9 is fixed by retainer plate 12.
Body 2 is cylindrical, and lid 1 and chassis 3 are all the circles matched with body 2, and circular round and smooth compared with other shapes, impurity easily rinses, and not easily remains.
Be provided with filter core firm banking 13 bottom outer filter core 9 and inner filter core 8, external filter core and inner filter core are reinforced, and can resist the current of greater impact power.
Outer filter core 9 is supported by screen support rod 14, realizes external filter core and reinforces, and extends filter screen service life.
Rainwater enters from the second water inlet, after outer filter element filtering falls larger particles, again after inner filter core filters, rainwater is discharged from outlet pipe after the first water inlet again, after filtration after a period of time, intrinsic impurity buildups, now high speed clean water enters in body from the first water inlet, first inner filter core is impacted, rotary current carry the particulate contamination on most inner filter core surface and enter sewage draining exit, then high speed water jet impact second layer filter screen, take away the impurity of second layer screen surface, impurity is discharged by final realization, realize quick backwash, realize impurity and clean automation.
It is emphasized that: the foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
