Description

Draft tube

The present invention relates to a draft tube, and more particularly to a draft tube for use in water treatment applications.

Conventional wastewater treatment industry usually uses pipe fittings to separate pollutants and impurities when treating wastewater. Therefore, it is easy to cause pores of the filter (net), and the relevant equipment must be cleaned regularly to maintain normal operation.

Furthermore, for aquaculture producers, in order to maintain a high dissolved oxygen rate to avoid damage to farmed fish stocks, it is best known to use water trucks to draw water to promote water flow and increase dissolved oxygen in water. However, for the aquaculture industry, the increased dissolved oxygen is limited to the surface of the pool, and the water depth is more than one meter and five, and has no significant effect.

At the same time, the pool used for breeding will be deposited for a long time, and the various gases generated at the bottom of the pool will also affect the dissolved oxygen rate on the surface of the pool. The traditional waterwheel obviously cannot improve the sedimentation of the pool. Another potential risk of waterwheels is leakage and electricity. Because the motor is placed in the pool, there is a risk of leakage if the wires are damaged.

As described above, in view of the problems in the prior art, the novel creator has developed a method for effectively removing pool deposits by using the Venturi Principle, and high operating efficiency can increase the dissolved oxygen on the surface of the pool. Energy efficient Diversion tube.

The present invention proposes a draft tube comprising: a main body and an air introduction hole. Wherein, the main body is a hollow pipe body having an upper opening and a lower opening, and an annular rib is formed inside; a plurality of slots are opened at a pipe edge near the lower opening of the main body; and a pipe side of the main body is opened The side holes allow the draft tube to form a three-way tube body, and air is introduced into the main body from the side holes by a power unit.

The inner part of the upper open end of the main body is provided with a plurality of protruding ribs to enhance the agitation efficiency of the discharge. Due to the Venturi Principle, when the power unit introduces air into the main body, the main body generates a strong airflow and creates suction. The sewage, sludge or other stolen goods to be treated under the main body, ie It can be sucked up by the lower opening of the main body and discharged through the upper opening of the main body.

The draft tube of the present invention further comprises: an air introduction tube, the air introduction tube is connected to a power unit and a side hole of the main body, and the joint with the side hole is screwed, welded or integrally formed.

The draft tube of the present invention further comprises a sleeve, which is a hollow tube body having an upper opening and a lower opening, and is movably inserted into the main body from the lower opening of the main body, and one end of the sleeve is formed by an inclined end surface. a plurality of blocks and spiral ribs, the plurality of blocks are offset from the annular inclined ribs inside the main body, and the sleeve is combined with the main body; the end of the sleeve is provided with a plurality of guide grooves, which are close to the main body The plurality of slots in the opening at the opening correspond to the set of sewage, sludge or other stolen goods, etc. It is directly sucked up by the lower opening of the main body, and can be discharged from the upper opening of the main body through the guide groove of the sleeve through the guide groove of the sleeve and along the spiral rib.

Therefore, the draft tube of the present invention can be applied to wastewater treatment, aquaculture pools and the like. When used, the diversion tube is directly disposed vertically adjacent to the bottom of the wastewater pond or the aquaculture pond, and the upper opening of the main body is upward and downward. The opening is downward, when the air is supplied to the main body through the air introduction pipe, a strong suction force is generated, and the water flow, the sludge, the sediment, and the like are sucked from the lower opening of the main body, and then discharged from the opening of the main body to make oxygen It can be directly supplied to the bottom of the water, and increase the surface dissolved oxygen of the pool, which has high operation efficiency and at the same time achieves energy-saving effect.

The main body, the air introduction tube and the sleeve of the novel draft tube can be made of a plastic material such as polyvinyl chloride (PVC), polypropylene (PP) or rustproof metal.

With the above structure, the present invention can be used in combination with various water resources to achieve energy saving.

Another object of the present invention is that the structure is simple and does not require daily maintenance, and the product has a long service life, which can reduce the cost of consumables and reduce the cost. If it needs to be replaced, it can be replaced individually according to the components, which is simple and not technical. The only thing that needs to be maintained in this creation is the blower used. The blower can be installed in the shore, factory, and container house. It is quite easy to maintain. It does not require people to enter the water body and scare the aquatic creatures.

When the creation is used in winter, the heater can increase the room temperature in the work chamber, and the heat exchanger is brought into the water body through the creation by the blower, thereby increasing the temperature of the local area in the water pool to increase the aquaculture in the winter. The survival rate of the culture.
