Abstract
The utility model aims to solve the technical problem and provides a self sucking type jet device, which comprises a nozzle, air inlet pipes, an air-sucking pipe, a mixing pipe and a diffusing pipe, wherein a straight pipe is placed at a water outlet of the nozzle of the jet device; and the two sides of the nozzle are both provided with the air inlet pipes. The structure is reasonable, the energy consumption is reduced, and the oxygenation capacity is effectively improved.
Description
Technical field
The utility model relates to a kind of ejector, relates to a kind of self-priming ejector specifically.
Background technology
Jet-flow aeration in the sewage treatment process, be to utilize ejector that air-flow or solution-air mixed flow are imported the aeration tank, to increase the system of oxygen level in the liquid, water inlet by water pump lifting to nozzle, nozzle diameter reduces gradually, form high velocity flow, enter trunnion, the high speed current form parital vacuum in trunnion portion, a large amount of air are inhaled into trunnion, acutely mix with sewage, form air-water mixture and enter diffuser tube, flow velocity slows down, pressure increases, form powerful injection stream, a large amount of bubbles discharge, and reach the effect to sewage while aeration and stirring.Present ejector adopts one-sided air inlet, easily causes the air-flow shakiness, and the spray nozzle front end reducing is too fast, forms the stream that looses easily, and consumed energy causes its oxygenation capacity and dynamic efficiency low.Therefore, design a kind of rational in infrastructurely, cut down the consumption of energy, the ejector that improves oxygenation capacity is the technical problem that needs to be resolved hurrily.
The utility model content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of self-priming ejector is provided, and is rational in infrastructure, cuts down the consumption of energy, and effectively improves oxygenation capacity.
For solving the problems of the technologies described above, technical solution adopted in the utility model is, a kind of self-priming ejector comprises nozzle, inlet pipe, air suction pipe, mixing tube and diffuser tube, and straight tube is placed in its nozzle water outlet place, and the nozzle both sides all are provided with inlet pipe.
Above-mentioned self-priming ejector, its inlet pipe are curve bend, and inlet pipe oral area axis is parallel with nozzle axis.
Above-mentioned self-priming ejector, its straight tube are 10mm.
Self-priming ejector of the present utility model by improving the form of ejector inlet pipe and nozzle, two symmetric inlet pipe are set in the nozzle both sides, and the position of inlet pipe is parallel with nozzle.Adopt bilateral air inlet simultaneously, improve air imbibed quantity, and, guarantee the trunnion that enters of current quick and stable, improve coefficient of oxygen utilization at the straight tube of one section 10mm of nozzle water outlet place design.Effectively prevent the diffusing stream of water inlet, cut down the consumption of energy, improved oxygenation capacity, reduced working cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in the figure, self-priming ejector of the present utility model comprises nozzle 1, inlet pipe 2, air suction pipe 3, mixing tube 4 and diffuser tube 5, and straight tube 6 is placed in nozzle 1 water outlet place, and nozzle 1 both sides all are provided with inlet pipe 2.Inlet pipe 2 is a curve bend, and inlet pipe 2 oral area axis are parallel with nozzle 1 axis.Straight tube 6 is 10mm.
The above, only be to preferred embodiment of the present utility model, be not to be that the utility model is done other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
