Abstract

The utility model provides an ultrasonic impulse nozzle. The ultrasonic impulse nozzle comprises a shell, seals and a core body. One end of an inner cavity of the cylindrical shell is open, the other end of the inner cavity of the cylindrical shell is closed in a cone shape, and only a small hole is formed in the center of the other end of the inner cavity of the cylindrical shell. One end of the cylindrical core body is cylindrical, and the other end of the cylindrical core body is in a cone shape. An extremely thin hollow channel is arranged in the center of the core body. The hollow channel is closed at the cylindrical end and is open at the cone-shaped end so that the hollow channel can be connected with the external air. The core body is inserted into the inner cavity of the cylindrical shell from the opening end. The outer diameter of the core body is slightly smaller than the inner diameter of the shell. The cone portion of the core body is slightly smaller than the small hole in the cone-shaped closed end of the shell. The position, close to the cone-shaped closed end, of the shell is provided with a water connector. The position, close to the opening end, of the shell is provided with an air connector. Sealing grooves are formed in the position, between the water connector and the air connector, of the core body and the position, between the air connector and the opening end of the shell, of the core body respectively. The seals are arranged in the sealing grooves. Airtight space is formed between the shell, the seals and the core body. An air guide hole is formed in the wall of the core body in the airtight space so that the space can be communicated with the hollow channel of the core body.

Description

Ultrasonic impulse nozzle

Technical field

The application relates to cleaner field, mine

Background technology

Nozzle is that current are changed into water smoke, and water smoke is the needed resource of yard, and great majority are as falling chalk dust removing.The problems such as most nozzle is common low-pressure nozzle, no matter is single head or the nozzle of bull, no matter includes which type of water guide core, all exists condensation rate low, and water smoke kinetic energy is also very low, and atomization cone angle is less, and required resource energy consumption is higher.

Water fog particle size has direct relation with efficiency of dust collection, and the less efficiency of dust collection of water fog particle is higher.Condensation rate is low is exactly that water fog particle is larger, so common low-pressure nozzle, as dust removal installation, is the poorest facility of effect.

The with serious pollution place of many dust from flying, as colliery mining face under mine, return aircourse, coal washery, cement plant, power plant etc., are used common low-pressure nozzle as dust removal installation, in order to reach dust-laying effect, increase nozzle quantity, strengthened water consumption, dust can only be reduced to a certain degree and pollute still and exist, and excessive use water source causes production passive, current cause disaster, conversely, close common low-pressure nozzle or the common low-pressure nozzle of discontinuity switch, for the improvement of dust, do not reach dreamboat.

The nozzle using is at present single fluid (liquid) nozzle mostly, because pressure of supply water low (being generally less than 10MPa) causes atomizing particle diameter large, for respirable dust, can not play effective depositing dust effect.

This invention is to have applied ultrasonic vibration principle to be made.Its working mechanism is: source of the gas and water source provide certain air pressure and hydraulic pressure, and source of the gas is pressure gas from the input of gas interface, and water source is inputted press water from water interface.Pressure gas through the input of gas interface enters the space that housing and core body and sealing form, and the centre bore that the pore fabrication hole at Zai Cong center enters core body flows to the right, arrives the conical surface place of core body and housing right-hand member.Press water through the input of water interface enters the space that right side housing and core body and sealing form, press water is inevitable to flow to the right, through water guide core, produce rotary water current, again along the gap of the conical surface of core body and housing right-hand member, the center that flows to of the cone angle High Rotation Speed forming with the conical surface runs into the air-flow penetrating at a high speed to the right, the air-flow of streamlined flow meets with there being the current of certain angle rotation, there is fierce collision, the influence of hydraulic pressure that on air-flow, certain is a bit arrived simultaneously and compressing, but because of the continuous instantaneous expansion of air pressure, current are spread by anti-cone angle direction.At the confined space current of housing and core body right-hand member and the collision repeatedly of air-flow, compress and expansion, just produced ultrasonic resonance phenomenon, current are excited into trickle particle by outwards ejection at a high speed of the angle after resonating.The adjusting nut that regulates core body rear portion, makes resonant frequency in ultrasonic range, and spout just produces the jet that atomization is good, cone angle is large, impact kinetic energy is high.

Beneficial effect:

1, the water guide core that adopts the core body right-hand member of special design, making, has reduced water consumption greatly.

2, the core body central guiding pore that adopts special design, making, reduces air consumption greatly.

3, the cone match between core body right-hand member and housing, the water yield that realizes press water regulates.

4, rotation adjusting nut changes resonance parameter, makes resonant frequency in ultrasonic range, produces splendid atomization and spray angle.

5, the conventional fittings body of the gentle interface kit of water interface, facilitates scene to install and use.

The specific embodiment

This invention is to have applied ultrasonic vibration principle to be made.Its working mechanism is: source of the gas and water source provide certain air pressure and hydraulic pressure, and source of the gas is pressure gas from gas interface (6) input, and water source is inputted press water from water interface (2).Pressure gas through gas interface (6) input enters the space that housing (1) and core body (5) and sealing (3) form, and the centre bore that the pore fabrication hole at Zai Cong center enters core body (5) flows to the right, arrives the conical surface place of core body (5) and housing (1) right-hand member.Press water through water interface (2) input enters the space that right side housing (1) and core body (5) and sealing (3) form, press water is inevitable to flow to the right, through water guide core, produce rotary water current, again along the gap of the conical surface of core body (5) and housing (1) right-hand member, the center that flows to of the cone angle High Rotation Speed forming with the conical surface runs into the air-flow penetrating at a high speed to the right, the air-flow of streamlined flow meets with there being the current of certain angle rotation, there is fierce collision, the influence of hydraulic pressure that on air-flow, certain is a bit arrived simultaneously and compressing, but because of the continuous instantaneous expansion of air pressure, current are spread by anti-cone angle direction.At housing (1) and the confined space current of core body (5) right-hand member and the collision repeatedly of air-flow, compress and expansion, just produced ultrasonic resonance phenomenon, current are excited into the angle outwards at a high speed ejection of trickle particle after by resonance.The adjusting nut (4) that regulates core body (5) rear portion, makes resonant frequency in ultrasonic range, and spout just produces the jet that atomization is good, cone angle is large, impact kinetic energy is high.
