Abstract
The utility model discloses an air-pressure type under-ice aerator comprising a supporting frame (5), a rack (3), a motor (1), an external protective supporting sleeve (9), a hollow air-pressure shaft (7), boosting blades (6), a negative-pressure aerating wheel (11) and the like, wherein the supporting frame (5) and the rack (3) support a main machine together; the motor (1) and the hollow air-pressure shaft (7) are directly connected by a flexible disc-type coupling (4); the front end of the external protective supporting sleeve (9) is connected with a rack flange (2), and the tail end thereof is connected together with the hollow air-pressure shaft (7) by a polyurethane flexible sleeve (10); and the negative-pressure aerating wheel (11) is arranged at the tail end of the hollow air-pressure shaft (7). The front end of the hollow air-pressure shaft (7) is provided with a plurality of spiral boosting air inlets (12); the boosting blades (6) are arranged at the outer diameter positions of the spiral boosting air inlets (12); and when in rotation, the air is brought in forcibly, the air inflow quantity is increased, the negative-pressure aerating wheel (11) at the tail end stirs the water flow to form a negative pressure space, and larger pressure difference brings a large amount of air into the water body, thus greatly increasing oxygen-dissolving quantity. The air-pressure type under-ice aerator has simple structure, and reliable performance, and is convenient for use and easy for operation.
Description
Affiliated technical field
The utility model relates to a kind of subglacial vapour-pressure type aerator, is suitable for the oxygenation of north of china in winter fish pond, belongs to fishery cultivating machinery.
Background technology
Aerator is the equipment that in the aquaculture fishes and shrimps is had lifesaving and facilitating effects.The prior mechanical aerator mainly contains Waterwheel-type, vane type, several major types such as water jet, and its principle all is the rotations by impeller, stirs water body and produces the spray, increases the water body dissolved oxygen amount, prevents that fish Uu from raising the nose above water to breathe because of anoxic.But use because the restriction of its structural principle is difficult in north subglacial cold season, and the power requirement is high, running noise is big, easily fishes and shrimps is damaged.A kind of jet aerator is also arranged, only depend on impeller to make the water flow at high speed form negative pressure, air is brought into increases the water body dissolved oxygen amount in the water, and acting surface is little, and dissolved oxygen amount is low, and efficient is low, poor reliability.
Summary of the invention
This is suitable for the novel technical problem that will solve is the defective that overcomes prior art, and a kind of novel subglacial vapour-pressure type aerator is provided, and forces plenum on ice, and subglacial stirs water oxygenation, and is simple in structure, and dissolved oxygen amount is big, the efficient height.
The technical scheme that its technical problem that solves the utility model adopts is: motor (1) with protect support set (9) outward and link together by frame flange (2), hollow airpressure axle (7) is connected by flexible disc type shaft joint (4) with motor (1) axle, hollow airpressure axle (7) is terminal to be positioned outer support set (9) end that protects by polyurethane flexible cover (10), supercharging blade (6) is positioned at hollow airpressure axle boost port (12) to be located, and negative pressure oxygenation wheel (11) is positioned at hollow airpressure axle (7) end.
Second major technique feature of the present utility model is: hollow airpressure axle (7) front end has a plurality of spiral boosting air inlets (12), and spiral boosting air inlet (12) side is with tilting screw supercharging blade (6).
The 3rd major technique feature of the present utility model is: upward uniform air inlet (8) position is corresponding with protecting support set (9) outward for the spiral boosting air inlet (12) on the hollow airpressure axle (7).
The 4th major technique feature of the present utility model is: the supercharging blade (6) on the hollow airpressure axle (7) is tilted parabola shape, with spiral boosting air inlet (12) sidewall II (14) smooth excessiveness.
The 5th major technique feature of the present utility model is: spiral boosting air inlet (12) the sidewall II (14) on the hollow airpressure axle (7) becomes the α angle with the normal direction axis, and sidewall I (13) becomes the β angle with the normal direction axis.
The beneficial effects of the utility model are: solved the north of china in winter subglacial oxygen weary problem of bursting, it is big to have an admission pressure, and air inflow is big, water body dissolved oxygen amount height, and operation is wide, and characteristics such as operating efficiency height reduce the fishes and shrimps loss, improve output, increase fisherman's income.Complete machine structure is simple, and is easy to operate, and stable performance is economical and practical.
