Technical field

The utility model is used for back-flushing filtering device field, combines recoil filter wash more particularly to a kind of automatic air-water Pond.

Background technique

In order to realize the recycling of water resource, need to be filtered surface water, underground water and production waste water etc.；Usually Using common pump type filter device, although which is widely used, but power consumption is high, filter efficiency is low；And due to being flowed by pump Amount and lift limit, and in flow plane productive set, can not be suitable for large area and filter, versatility is poor；Become simultaneously in filtering layer resistance After big, backwash pump and the artificial backwash water source valve of control manually need to be increased to realize backwash process；In this process In, flushing dose and backwash rate all need artificially to manually control, and are easy to appear and rinse insufficient or rinse excessive drawback, and it is strong to work It spends larger；Backwashing period also not in time, is easy to produce the case where water treatment can not be up to standard or exceeds claimed range, stability Difference.To solve the above-mentioned problems, occurs dynamic hydrocone type back-flushing filtering device in the prior art, but this filter device is only There is water body backwash mode, without gas back-flushing, still remains that working efficiency is low, recoil is not thorough, washing water quantity is big, restores Performance is bad, rinses the problems such as water impurity is more.

Utility model content

The purpose of this utility model is to provide a kind of automatic air-waters to combine backwash filter tank, in conjunction with gas punching, water punching etc. Mode is backwashed, and work efficiency is high, recoil is more thorough, restorability is good.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of automatic air-water joint recoil filter wash Pond, including filter tank, bell jar and recoil tracheae, are equipped with filter layer in filter tank, and bell jar covers on the filter layer top, bell jar connect into Water pipe and siphon pipe, filter tank the lower section of filter layer be equipped with clear water zone, filter tank the top of bell jar be equipped with gathering ground, gathering ground with Clear water zone communicates, and the recoil tracheae is equipped with check-valves, and recoil tracheae has the air inlet communicated with the outside world, and recoil tracheae exists Clear water zone is equipped with gas outlet.

It is further used as the improvement of technical solutions of the utility model, siphon pipe is equipped with auxiliary siphon tube, auxiliary siphon tube End protrude under the liquid level of gathering ground.

It is further used as the improvement of technical solutions of the utility model, further includes the whirl spraying device of air being located in clear water zone, is revolved Air-jet device and recoil tracheae are connected, and whirl spraying device of air has the fumarole being obliquely installed, and whirl spraying device of air can be in fumarole It is rotated under the action of middle recoil air-flow.

It is further used as the improvement of technical solutions of the utility model, is equipped with bell jar interface tube, the water inlet pipe at the top of bell jar It is docked after being connected with siphon pipe by threeway with bell jar interface tube.

It is further used as the improvement of technical solutions of the utility model, further includes high water tank, the water inlet end and height of water inlet pipe Position water tank connection.

It is further used as the improvement of technical solutions of the utility model, filter tank is equipped with effluent weir in gathering ground.

It is further used as the improvement of technical solutions of the utility model, the filter layer includes sand filter blanket.

The utility model has the beneficial effects that after filter layer blocking is serious, leading to siphon pipe water after operating normally a period of time Position rises, and ultimately forms siphon, at this time can be by the siphon outward energetically of the water body in clear water zone, and the air inlet for the tracheae that recoils this moment is inhaled Enter air, air enters clear water zone by recoil tracheae, to produce combined water and air backwash effect.The utility model combines Gas punching, water rush isotype and are backwashed, and work efficiency is high, recoil is more thorough, restorability is good.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawing:

Fig. 1 is the utility model embodiment structural schematic diagram.

Specific embodiment

Referring to Fig.1, that show the specific structures of the preferred embodiment of the utility model.It will be detailed below this reality With the design feature of novel each component.

The utility model provides a kind of automatic air-water joint backwash filter tank, including filter tank 1, bell jar 2 and recoil tracheae 3, filter tank 1 is interior to be equipped with filter layer 4, any one filter structure in the prior art, such as strainer, grid can be used in filter layer 4 Deng preferably, the filter layer 4 includes sand filter blanket.Bell jar 2 covers on 4 top of filter layer, and bell jar 2 connects 5 He of water inlet pipe Siphon pipe 6, filter tank 1 are equipped with clear water zone 7 in the lower section of filter layer 4, and filter tank 1 is equipped with gathering ground 8, gathering ground 8 in the top of bell jar 2 It is communicated with clear water zone 7, the recoil tracheae 3 is equipped with check-valves 9, and recoil tracheae 3 has the air inlet communicated with the outside world, recoil Tracheae 3 is equipped with gas outlet in clear water zone 7.

Normal workflow: when normal operation, sewage is intake from water inlet pipe 5, and by bell jar 2, passageway filter layer 4 is filtered, Clear water rises to gathering ground 8 from clear water zone 7 and is discharged.

After operating normally a period of time, after filter layer 4 blocks seriously, causes 6 water level of siphon pipe to rise, ultimately form rainbow It inhales, at this time can be by the siphon outward energetically of the water body in clear water zone 7, the air inlet for the tracheae 3 that recoils this moment sucks air, and air passes through The tracheae 3 that recoils enters clear water zone 7, to produce combined water and air backwash effect.The moulds such as the punching of the utility model combination gas, water punching Formula is backwashed, and work efficiency is high, recoil is more thorough, restorability is good.

In order to assist the gas in discharge siphon pipe 6 in siphon formation stages, siphon pipe 6 is equipped with auxiliary siphon tube 10, In order to avoid after siphon is established, auxiliary siphon tube 10 introduces gas, and the liquid level of gathering ground 8 is protruded into the end of auxiliary siphon tube 10 Under.

Recoil tracheae 3 can be directly protruding into clear water zone 7, further include the rotation being located in clear water zone 7 alternatively Air-jet device, whirl spraying device of air and recoil tracheae 3 are connected, and whirl spraying device of air has the fumarole being obliquely installed, whirl spraying device of air Can recoil in fumarole air-flow under the action of rotate.A kind of propulsive thrust can be formed when air projects, rotated automatically Come, 360 degree of realization is without the comprehensive flushing in dead angle.

Water inlet pipe 5 and siphon pipe 6 can be connect with bell jar 2 respectively, preferably, being equipped with bell jar interface tube at the top of bell jar 2 11, the water inlet pipe 5 and siphon pipe 6 after the connection of threeway 14 with bell jar interface tube 11 by docking.

It further include high water tank 12, high water tank 12 can be integrated or separately arranged with filter tank 1, and height is higher than bell jar 2, high For storing water to be filtered, the water inlet end of water inlet pipe 5 is connect position water tank 12 with high water tank 12.

It is drawn in order to facilitate the drainage of crossing of gathering ground 8, filter tank 1 is equipped with effluent weir 13 in gathering ground 8.

Certainly, the invention is not limited to above embodiment, and those skilled in the art are without prejudice to originally Equivalent deformation or replacement can be also made under the premise of utility model spirit, these equivalent variation or replacement are all contained in the application In claim limited range.
