The electric motor performs air sound conversion when driving the turntable to rotate so that the strength of output air is greatly increased, the sound power is greatly improved, the generated wave length is longer with slow attenuation, a uniform energy field can be formed in a work area, the frequency of sound wave can reach 140-1000 Hz, and the sound power level is more than 152 dB, thereby the utility model can effectively prevent and break the combination of dust particles, can cause dust deposition layers fall off from equipment such as boilers, heat exchangers, dust removers, blades of fans, flues, and the like, and has favorable dust cleaning effect. The utility model can substitute and improve the traditional dust cleaning method, lowers the maintenance cost of the equipment, greatly lightens the working intensity, improves the work efficiency of the equipment, prolongs the service life of the equipment, saves energy sources and human resources, and has remarkable social and economic benefits.
Description
Technical field
The utility model relates to cleaning equipment, relates in particular to the deashing device of equipment such as being used for power plant, the various sack cleaners of steel plant, electrostatic precipitator, Industrial Boiler, fan blade, flue.
Background technology
At present because the use of sound wave ash cleaner on equipment such as Industrial Boiler, sack cleaner, electrostatic precipitator, make that the dust stratification of its equipment inwall and flue internal face is in time cleared up, labor strength and maintenance condition have not only been improved greatly, improved operating efficiency, prolonged the service life of equipment, greatly reduced simultaneously the personal safety hidden danger of deashing operation under the hazardous environment condition, but because the acoustic energy that is produced is little, its ash-removal effect is not good enough, makes equipment inner surface dust stratification can not get effective cleaning.
Summary of the invention
The utility model provides a kind of low-frequency sound wave deashing device with siren pressurized generator, the acoustic power level of its generation〉152dB (A) and have bigger acting ability, act on vibration force on dust stratification layer and the dust particle with raising, equipment inner surface dust stratification is effectively cleared up.
The utility model purpose realizes in the following manner, this low-frequency sound wave deashing device comprises the sonic generator that is installed on the supporting seat, the sonic generator two ends are connected with air inlet pipe and acoustic waveguide tube respectively, it is characterized in that described sonic generator comprises blade that is fixed on successively on the axis body and the rotating disk that mates with sonic generator housing internal diameter, offer the air-flow through hole on the rotating disk, axis body is in transmission connection by shaft joint and the motor that is assemblied on the sonic generator housing.
The air-flow through hole of offering on the described rotating disk is 1～6, and the air-flow through hole evenly distributes on the same circumference of rotating disk.
Described blade is at least 2, and each blade far-end forms crooked in the same way.
The distance that described bending blade is put between the rotating disk center of circle is identical with air-flow through hole place radius of a circle.
Described blade is more than 3 or 3.
The technological progress that the utility model is obtained:
Because blade and the rotating disk that offers the air-flow through hole are set on the axis body in sonic generator, when driving the rotating disk rotation by shaft coupling, motor rotating at high speed carries out the conversion of gas sound, cause the gas intensity of output greatly to strengthen, acoustical power improves greatly and strengthens, energy gets conversion to the limit, the wavelength that is produced is longer, decay is slow, formed propagation, transmission, the characteristics that refracting power is strong, can form balanced energy field in the working region, after testing, frequency of sound wave can reach 140HZ～1000HZ, the acoustic power level of generation〉152dB (A), not only can effectively stop and destroy the combination of dust particle, the boiler of the dust stratification layer that can effectively make simultaneously deposition under the running status, heat exchanger, deduster, fan blade, come off on the equipment inwalls such as flue, produced good ash-removal effect.Can be widely used in the dust stratification equipment of industries such as power plant, metallurgy, iron and steel, the purge mode (water, vapour and mechanical vibrator) alternative and improvement is traditional, alleviate labor strength greatly, reduce the maintenance of equipment expense, can effectively improve the equipment operating efficiency, prolong its service life, energy savings and human resources have remarkable economic efficiency and social benefit.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the sonic generator structural representation of Fig. 1.
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Embodiment 1: as Fig. 1～shown in Figure 3, this low-frequency sound wave deashing device that the utility model relates to is the improvement of carrying out on existing sound wave ash cleaner basis, its improvement project part is, assembling sonic generator 5 on supporting seat 2, the upper end of sonic generator 5 connects air inlet pipe 2, following termination acoustic waveguide tube 1, the acoustic waveguide tube 1 terminal horn mouth that forms, be a cylindrical cavity in sonic generator 5 housings, assembling axis body 11 in the cavity, 3 blades 9 and rotating disk 8 successively are connected on the axis body 11, offer 3 air-flow through holes 10 on the rotating disk 8, rotating disk 8 diameters and sonic generator 5 housing internal diameters coupling, each blade 9 far-end forms crooked in the same way, and its cross section forms the shape of a saddle, blade 9 bending points are identical with air-flow through hole 10 place radiuss of a circle to the distance between rotating disk 8 centers of circle, air-flow through hole 10 evenly distributes on rotating disk 8 same circumference, and blade 9 axially fully stretches along cylindrical cavity in sonic generator 5, and axis body 11 is in transmission connection with 7 companies of motor that are assemblied on sonic generator 5 housings by shaft joint 6.
Embodiment 2: the present embodiment difference from Example 1 is that blade 9 is more than 2 or 3.
Those skilled in the art or those skilled in the art are except that foundation the various embodiments described above disclosed in the utility model, the quantity of rotating disk 8 overdraught through holes 10 and the quantity of blade 9 one-tenth numerous embodiments also capable of being combined, these modes all should be understood in scope of the present utility model, are subjected to the restriction of the utility model claim.
The utility model operation principle and the course of work are: when the blade 9 on the 0.25KW motor 7 drive axis bodies 11 rotates at a high speed, 0.4 the air of～0.7Mpa or nitrogen gases at high pressure 4 enter in the cylindrical die cavity of sonic generator 5 from the body porch when magnetic valve 3 instruction unpacks by the road, promoting shape of a saddle blade 9 rotates, because motor 7 high speed rotating, gas is squeezed into the high pressure draught of High Voltage in die cavity, make gases at high pressure supercharging once more in sonic generator 5 chambeies, then by equally distributed air-flow through hole 10 cutting high pressure draughts on the rotating disk 8 and through 10 outputs of air-flow through hole, the high pressure draught of output forms the high strong sound wave of different frequency, high strong sound wave enters acoustic waveguide tube 1 and sends acoustic power level until horn mouth by air-flow through hole 10〉the ring sound of 152dB (A), air consumption is 40～55L/S during the ring sound, acoustic energy passes to the energy field of the working region formation high sound intensity of equipment, this energy field makes grey particle form concussion, stop between grey particle and the combining of grey particle and equipment room, to forming the grey particle of dust stratification layer, because macroseism is swung it is come off from the dust stratification surface, reaches effective deashing purpose.
