Connection, the suction chamber connect gas-guide tube, and the straight tube bottom is equipped with support base, and the support base and the tank base connect
It connects；The top of the tank is equipped with bulge-structure, and the bulge-structure is equipped with backwash interface, and the backwash interface is arranged described
Above gas-guide tube.
The top of the gas-guide tube is arranged in the bulge-structure.The bend pipe is U-tube.
The beneficial effects of the utility model are: the utility model structure is simple, manufacturing cost is low, molten gas effect is good, can be with
Air guide pipe choking is prevented, by adding down-set bend pipe in ejector exit, the air water after the molten gas of level-one is mixed
It closes liquid and introduces the water surface hereinafter, forming the molten gas of second level, considerably increase gas-water ratio, improve mixing wastewater with air degree, to increase molten
Gas effect.The utility model will be arranged in the bulge-structure of top of the tank at the top of gas-guide tube, greatly reduce gas-guide tube
The probability of obstruction can be rinsed gas-guide tube by the way that the backwash interface above gas-guide tube is arranged in once blocking, only
It needs one minute or so that obstruction can be removed, has ensured the continuous and steady operation of system, reduced Maintenance and Repair cost, very
It is suitably applied in large-scale sewage disposal system.The support base of the utility model prevents in dissolving for consolidating ejector
Portion's turbulent flow impacts ejector, guarantees molten gas effect.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
With reference to the accompanying drawings 1, the utility model is that a kind of anti-blocking is separated by solid-liquid separation dissolving, including tank body 1 and ejector 2, institute
It states 1 two sides of tank body and is respectively equipped with water inlet 3 and access hole 4, air inlet 5, pressure gauge connection 6 are respectively equipped at the top of the tank body 1
With relief valve connection 7,1 bottom of tank body is equipped with water outlet 8, and 1 top of tank body is equipped with liquidometer 9；The ejector 2 wraps
Sequentially connected nozzle 10, suction chamber 11, diffuser pipe 12, straight tube 13 and bend pipe 14 are included, the bend pipe 14 is down-set, the spray
Mouth 10 is connect with the water inlet 3, and the suction chamber 11 connects gas-guide tube 15, and 13 bottom of straight tube is equipped with support base 16, institute
Support base 16 is stated to connect with 1 bottom of tank body；It is equipped with bulge-structure 17 at the top of the tank body 1, is set on the bulge-structure 17
There is backwash interface 18, the backwash interface 18 is arranged above the gas-guide tube 15.
The top of the gas-guide tube 15 is arranged in the bulge-structure 17.The bend pipe 14 is U-tube.
The course of work of the utility model is as follows: liquid by high-pressure pump from water inlet 3 enter ejector 2 in, liquid with
High speed is sprayed from nozzle 10, can form vacuum in suction chamber 11 when swiftly flowing liquid passes through suction chamber 11, suction chamber 11 is logical
The air that gas-guide tube 15 sucks 1 top of tank body is crossed, mixing wastewater with air liquid is introduced by liquid level or less by bend pipe 14 after mixing wastewater with air
Secondary mixing is carried out, the molten gas of second level is formed, considerably increases gas-water ratio, improve mixing wastewater with air degree, increase molten gas effect, so
Flotation tank is flowed by water outlet 8 by the mixing wastewater with air liquid after the molten gas of second level.
The top of the gas-guide tube 15 is arranged in the bulge-structure 17 at 1 top of tank body, greatly reduces the hair of gas-guide tube 15
The probability of raw obstruction can open backwash interface 18 and be rinsed to gas-guide tube 15 once blocking, it is only necessary to one minute left side
The right side can remove obstruction, ensure the continuous and steady operation of system, reduce Maintenance and Repair cost, be highly suitable to be applied for big
In the sewage disposal system of type.The support base 16 prevents dissolving internal turbulence from making to ejector 2 for consolidating ejector 2
At influence, guarantee molten gas effect.
As the air in tank body 1 is constantly soluble in water and is discharged, the air in tank body 1 is reduced, and liquid level rises, and works as tank
When liquid level in body 1 is higher than the liquid level that liquidometer 9 is set, liquidometer 9 issues signal, carries out tonifying Qi, and compressed air passes through air inlet
Mouth 5 enters tank body 1, makes pressure increase in tank body 1, causes to reduce into water, water outlet increases, reduces liquid level, be down to and set when liquid level
When determining liquid level, liquidometer 9 issues signal, stops tonifying Qi.
The utility model is equipped with safety valve and pressure gauge by relief valve connection 7 and pressure gauge connection 6, when in tank body 1
Pressure be more than pressure gauge setting rated pressure when, safety valve, which automatically opens, to be released stress, and the utility model can be with time control
The size of pressure in tank body 1 processed, it is ensured that the safety of equipment operation and the safety of staff.
Above-described embodiment is merely to illustrate the utility model rather than limitation the scope of the utility model, it should be appreciated that
After the content for having read the utility model elaboration, those skilled in the art can make different form but effect to the utility model
Identical various changes or modification, these equivalent forms modify the range for equally falling within the limited protection of the claim of this application book
Within.
