Abstract

The utility model provides a microporous aeration device. The microporous aeration device comprises a blower, an air delivery pipe and an aerating disc, wherein the air delivery pipe is connected with an air outlet of the blower; the aerating disc is formed by a spirally winding aeration pipe and is gradually lifted from the center to the periphery; the two ends of the aeration pipe are connected with each other by a connecting pipe; a joint pipe is arranged in the center of the aerating disc around a winding axis of the aeration pipe; the two ends of the joint pipe are respectively connected with the connecting pipe and the air delivery pipe; an impeller is arranged on the joint pipe and is arranged on the outer wall of the joint pipe in a sleeving manner via a bearing; the axial direction of the impeller and the joint pipe form an included angle of 10-30 degrees; the aeration pipe is formed by an inner pipe and a breathable spongy layer wrapping the outer surface of the inner pipe; air holes running through the pipe walls are distributed on the pipe walls of the inner pipe. The microporous aeration device avoids the problem that the lower air holes are not smooth in venting because the aerating disc sinks to the water bottom, also endows the aerating disc with driving force for prompting the aerating disc to move, enlarges the activity range of the aerating disc in water, and further improves the aeration effects.

Description

A kind of micro-pore aeration oxygen increasing device

Technical field

The utility model relates to a kind of oxygen-increasing device of water body, specifically a kind of micro-pore aeration oxygen increasing device.

Background technology

The method that improves at present water body dissolved oxygen amount mainly contains two kinds: aeration oxygen replenishing and oxygenation agent oxygenation, and wherein take aeration oxygen replenishing as main method.Aeration oxygen replenishing is divided into again two kinds of blast aeration and mechanical aerations.Mechanical aeration is exactly impeller, waterwheel, jetting type etc., by agitate water, causes water to contact with the interface of gas, can only solve the oxygenation of upper strata water body, and gas-to-liquid contact interface is interrupted, and contact area is little, and duration of contact is short.From noise aspect, mechanical aeration is placed directly in waterborne, and the sound of patting water is very large, affects the normal growth of aquatic organism.Blast aeration is that the air of blower fan being carried by pipeline passes into the bottom, carries out aeration from the bottom, can allow dissolved oxygen be distributed in whole water body.And it is best with microporous pipeline oxygenation effect in blast aeration, produce small bubble by the micropore on the pipeline of underwater, and the very small gas so of bubble and liquid contact surface are long-pending also just large, it is slow that bubble rises speed, duration of contact is just long, oxygen in gas is just more abundant like this, in more dissolving easily in water.But microporous aeration device design is at present perfect not, bubble distribution inequality, oxygenation effect needs further to improve.

Utility model content

Technical problem to be solved in the utility model is to provide the micro-pore aeration oxygen increasing device that a kind of bubble is tiny and be evenly distributed.

The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of micro-pore aeration oxygen increasing device, comprise gas blower, air delivery pipe and oxygen increasing disc, air delivery pipe is connected with the air outlet of gas blower, oxygen increasing disc forms the therefrom mind-set surrounding plate-like of lifting gradually by the oxygen increasing tube of volution coiling, the two ends of oxygen increasing tube interconnect by pipe connecting, be provided with a junction block at oxygen increasing disc center along the coiling axis of oxygen increasing tube, the two ends of junction block are connected with pipe connecting and air delivery pipe respectively, on junction block, be provided with an impeller, impeller by bearing housing on the outer wall of junction block, between the axial and junction block of impeller, there is angle.

On described oxygen increasing disc, be provided with the fixing muscle distributing radially.

The angle axially and between junction block of described impeller is 10 °-30 °.

The beneficial effects of the utility model are: the impeller of setting can be pushed rotation in the bubble uphill process of emerging, the local generation of water body rotatablely moved, and then make bubble rotation increase, and have promoted contacting of gas and water, improve increase effect.Tilt vane rotary time can also produce impellent, make oxygen increasing disc produce a buoyancy obliquely upward, the below breather hole of not only having avoided oxygen increasing disc to sink under water and to cause the not smooth problem of giving vent to anger, also make oxygen increasing disc there is a short impellent moving it, increase the scope of activity of oxygen increasing disc in water, further improved oxygenation effect.Be provided with ventilative spongy layer in the outside of oxygen increasing tube, can make the gas distribution that appears more even, and the bubble producing is more small, has improved oxygenation effect.Air delivery pipe is connected to the center of oxygen increasing disc, and when air blast gas transmission, oxygen increasing disc is more steady, and the bubble that the each position of oxygen increasing disc is produced rises uniformly, reduces the mutual collision between bubble, avoids bubble incorporation to increase volume.

Embodiment

Illustrate by reference to the accompanying drawings embodiment of the present utility model.

A kind of micro-pore aeration oxygen increasing device, comprise gas blower 1, air delivery pipe 2 and oxygen increasing disc 3, air delivery pipe 2 is connected with the air outlet of gas blower 1, oxygen increasing disc 3 forms the therefrom mind-set surrounding plate-like of lifting gradually by the oxygen increasing tube 301 of volution coiling, the tube wall circumference of oxygen increasing tube 301 is distributed with breather hole 302, the two ends of oxygen increasing tube 301 interconnect by pipe connecting 303, be provided with a junction block 4 at oxygen increasing disc 3 centers along the coiling axis of oxygen increasing tube 301, the two ends of junction block 4 are connected with pipe connecting 303 and air delivery pipe 2 respectively, on junction block 4, be provided with an impeller 5, impeller 5 by bearing housing on the outer wall of junction block 4, between the axial and junction block 4 of impeller 5, there is the angle of 10 °-30 °.Because the top and bottom of oxygen increasing disc 3 all have breather hole 302, and the air pressure of giving vent to anger is equal, and oxygen increasing disc 3 top and bottom are because the thrust producing of giving vent to anger is cancelled out each other, and therefore oxygen increasing disc can fall due to self gravitation.Arrange after impeller 5 according to the technical program, the gas of emerging in oxygen increasing disc 3 top and bottom all can move upward, thereby promote impeller 5, produce thrust upwards, select suitable impeller area can make oxygen increasing disc 3 float in water according to weight of equipment, thus the not smooth problem of having avoided oxygen increasing disc to sink under water and the below breather hole that causes is given vent to anger.Also make oxygen increasing disc there is a short impellent moving it simultaneously, increased the scope of activity of oxygen increasing disc in water, further improved oxygenation effect.

Described oxygen increasing tube 301 is made up of inner tube 304 and the ventilative spongy layer 305 that is wrapped in inner tube 304 outside surfaces, is distributed with the breather hole 302 that connects tube wall on the tube wall of inner tube 304.On described oxygen increasing disc 3, be provided with the fixing muscle 306 distributing radially.
