Abstract

The utility model provides a centrifugal oxygenation machine. When the rotor of the centrifugal oxygenation machine rotates, air can be automatically sucked. The sucked air is thoroughly mixed with the liquid added from a liquid inlet pipe in the filler layer of the rotor. Oxygen in the air is dissolved in the liquid. The centrifugal oxygenation machine can improve the oxygen dissolving efficiency and can be used for a liquid oxygenation process in the pisciculture and biochemistry industries.

Description

Centrifugal oxygenation machine

The utility model proposes a kind of centrifugal aeration device, be applicable to liquid dissolved oxygen process.

Traditional aeration device mostly is gas bubbling jar, groove or tower, and promptly by liquid in the jar, the efficient that this device gas phase oxygen dissolves in liquid is low in the bubbling mode for gas, and gas must be by several meters thick liquid layers, and energy consumption is very big.

Utilizing the effect reinforcement air of mechanical stirrer and the aeration device of liquid mixing effect, also is to produce to go up device commonly used.As stirring-type oxygenating machine used in the fish pond, lean on the effect of agitator that water is splash, with air mixed, efficient of this device oxygenation is lower, and energy consumption is bigger.And for example aeration device such as used turbine type in the breeding of aerobic organism or the aerobic fermentation process in the liquid, self-priming and outer circulation air lift type utilizes bubbling mode oxygenation basically, and therefore, the efficient of dissolved oxygen and speed aspect all do not have breakthrough raising.

The purpose of this utility model: utilize the effect of centrifuge field, suck air automatically, strong dispersion liquid makes air and liquid thorough mixing in the packing layer under the centrifuge field, thereby a kind of dissolved oxygen efficiency height, novel centrifugal oxygenating machine that energy consumption is low are provided.

In view of above-mentioned purpose, essential implementation of the present utility model is:

Power set (as motor) connects a rotor, and the filler anchor is arranged on the rotor, and one deck ring packing is housed between anchor at least.The gas passage that fluid passage is arranged on the anchor and packing layer is directly communicated with atmosphere makes air automatic inspiration packing layer when rotor rotates.Liquid-inlet pipe stretches in the space that packing layer encloses, and liquid sprays to packing layer by the spray hole on the pipe.In packing layer, air and liquid is thorough mixing under the effect of centrifuge field.

Above-mentioned filler anchor can be the plank frame that the surface has through hole, also can be closed-in construction.

Above-mentioned liquid-inlet pipe can be an immobilized, and liquid is by the pump input.

Liquid-inlet pipe can also be connected to become tumbler with rotor, and (bolting or welding) axially drain impeller or blade is housed in the pipe, and when impeller or blade were immersed in the liquid, liquid directly was imported into the mouth spray place of liquid-inlet pipe, gets rid of to packing layer.

For making rotor suck air better, on the filler anchor at rotor gas inlet place axial air guide impeller or blade can be housed.

The utility model rotor is outer can to cover casing, has fluid hole and inlet mouth on the casing.

Rotor can be, and place in vertical, horizontal or any orientation.

The filler of rotor can be metal or nonmetallic foam stuffing, also can be metal or nonmetallic silk screen, or the packing layer with certain specific surface and voidage of other weighting material composition.

Effect of the present utility model:

Owing to utilized the effect of centrifuge field, rotor can suck air automatically, and strong dispersion liquid makes air and liquid thorough mixing in the packing layer under the centrifuge field, greatly strengthened the dissolved oxygen process in the liquid, made the approaching and air balance of oxygen level in the liquid after the rotor ejection.This device dissolved oxygen efficiency height, energy consumption are low, can be widely used in liquid oxygenation process in pisciculture and the biochemical industry, improve throughput significantly.

Embodiment 1:

As shown in Figure 1: rotor 1 is supported on fixed support or the base, rotates under the driving of motor, and board-like filler anchor is arranged on the rotor, and the filler anchor is made up of filler basket 2 cover plates 3, and the surface of filler basket has through hole 4.Ring packing 5 is housed between the filler anchor.The cover plate center of anchor has ventilating pit, and the rotor center space 6 that filler is enclosed directly communicates with atmosphere, makes the automatic inspiration packing layer of air energy when rotor rotates.Axial air guide blade 7 is equipped with at the ventage place of cover plate, makes air suck the centre of rotor space better.Liquid is squeezed into liquid-inlet pipe 8 and is entered rotor by pump, sprays to packing layer by spray hole 9, mixes in packing layer with the rotor inhaled air, and airborne oxygen dissolves in the liquid.Then, around air and liquid were thrown toward together, liquid continued to exchange with the air mass transfer in atmosphere, falls into liquid cell at last.

Embodiment 2:

As shown in Figure 4, be used horizontal centrifugal oxygenating machine in the yeast production.Concentrate for ease of liquid, rotor 1 is covered with casing 10, has fluid hole 11 and inlet mouth 12 on the casing.In time discharge housing for ease of air, also have venting port 13 on the housing.

Embodiment 3:

As shown in Figure 5, liquid-inlet pipe 8 is connected with rotor, and spiral axial drain blade 14 is equipped with in the inside, lower end of liquid-inlet pipe, when blade is immersed in the liquid, and inspiration liquid automatically, liquid sprays to packing layer by the spray hole on the liquid-inlet pipe 9.
