Abstract

The utility model provides a beneficiated-type low noise multi-functional acoustic dedusting machine, which is composed of an acoustic vibration cavity 1 provided with a muffler, a sound reinforcement section 2, a horn 3, etc. A front muffler 8 and a back muffler 7 totally encloses the part out of a furnace or a container of the acoustic dedusting machine; the connection of the acoustic vibration cavity 1 and the sound reinforcement section 2 is a welded structure; the outline of the inner wall of the sound reinforcement section 2 and the horn 3 is designed into a hyperbolic curve, the cross section of the sound reinforcement section 2 is circular, the cross section of the horn 3 is rectangular or circular. The adoption of the structural acoustic dedusting machine can generate the optimum dedusting effect to various equipments and the ash with different materials and ensure no sound leakage and air leakage, free maintenance and no noise pollution to the internal environment of a factory building.

Description

Synergistic type low noise multipurpose acoustic wave soot blower

The utility model provides a kind of vibration flake type acoustic wave ash remover, is meant a kind of Synergistic type low noise multipurpose vibration flake type acoustic wave ash remover especially.

The utility model product belongs to the electrical category product, is mainly used in the electrostatic precipitator in cement plant, various sack cleaner, hopper, material storehouse; The boiler in thermal power plant and high voltage electrostatic dust precipitator; Also be applicable to big-and-middle-sized powder container, feed bin and the conveying pipe etc. of feed factory, ceramics factory, charcoal ink factory, washing powder factory and dry milk factory.It can remove the dust stratification and the incrustation of high-voltage electrostatic dust separator polar curve, pole plate, ash bucket and wall; Remove the dust of sack cleaner; Peel off the black dirt on boiler heat-exchanger surface; Improve feed bin Flow of Goods and Materials etc.

Existing vibration flake type acoustic wave ash remover is when sending powerful sound wave and entering boiler or other container deashing scale removal, and the noise that acoustic wave soot blower produces stove outside or container outside causes certain influence to the health of operating the operations staff, makes the decline of people's hearing, mood agitation.General employing that be connected between the acoustic vibration chamber of vibration flake type acoustic wave ash remover and the public address section is threaded and seals, its shortcoming is under the vibration of powerful sound wave and under the effect of the positive and negative moment of air inlet steel pipe rising-heat contracting-cold, the normal appearance of this connection is loosening, cause acoustic wave soot blower gas leakage leakage sound, even lost efficacy, must on-call maintenance.In addition, existing acoustic wave soot blower far can not adapt to the structural requirement of different industries various kinds of equipment such as cement plant, thermal power plant, feed factory, ceramics factory, charcoal ink factory, washing powder factory and dry milk factory, and necessary otherwise designed satisfies conglomerate, multiduty demand.

The purpose of this utility model is the shortcoming that exists at above-mentioned prior art, and a kind of air tight, noise is low, applicability is wide Synergistic type low noise multipurpose vibration flake type acoustic wave ash remover is provided.

For achieving the above object, it is rectangle or circular loudspeaker for the hyperbola cross section that acoustic wave soot blower of the present utility model adopts acoustic vibration chamber that muffler is housed and public address section, contour curve, acoustic vibration chamber and public address section be connected the employing welded seal.

After adopting such structure,, thereby can absorb the noise that the dust remover body produces because acoustic vibration chamber and public address section are equipped with muffler; Because welded seal is adopted with being connected of public address section in the acoustic vibration chamber, connect loosening and gas leakage leakage sound thereby can eliminate, freedom from repairs; Because the contour curve of public address section and loudspeaker adopts hyperbola, its cross section employing rectangle or circle and black dirt material and device structure are complementary again, thereby have increased the operating efficiency and the adaptive surface of dust remover.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a drawing in side sectional elevation of the present utility model.Characteristics of the present utility model are:

As shown in Figure 1, main body of the present utility model is made up of acoustic vibration chamber 1, public address section 2 and the loudspeaker 3 made with stainless steel.Welding is adopted with being connected of public address section 2 in acoustic vibration chamber 1, the flange that is connected to of public address section 2 and loudspeaker 3 adds securing member and is connected, compressed air enters acoustic vibration chamber 1 by air inlet pipe 6 and cool air hose 5, drive 4 vibrations of titanium alloy diaphragm, produce low frequency high strength sound wave, process section of amplifying 2 and loudspeaker 3 are amplified into the ash deposit and slag buildup zone of boiler or other containers 13, under the concussion of powerful acoustic energy, remove black dirt.

Preceding muffler 8 is cylindrical or square, and interior filling sucting sound material 12 is installed on the public address section 2; After silencer 7 is cylindrical shape or square, and liner sound-absorbing material 11 and stainless steel cloth 10 cover on the acoustic vibration chamber 1.

During use, above-mentioned Synergistic type low noise multipurpose vibration flake type acoustic wave ash remover is installed on boiler or other chamber walls 13 by flange 9, compressed air enters acoustic vibration chamber 1 by air inlet pipe 6 and cool air hose 5, drive 4 vibrations of titanium alloy diaphragm, produce low frequency high strength sound wave, process section of amplifying 2 and loudspeaker 3 are amplified into the ash deposit and slag buildup zone of boiler or other containers, under the concussion of powerful acoustic energy, remove black dirt.

Claims

1, a kind of Synergistic type low noise multipurpose acoustic wave soot blower, form by acoustic vibration chamber 1, public address section 2, loudspeaker 3, alloy diaphragm 4, air inlet pipe 6 and cool air hose 5, preceding muffler 8, after silencer 7 etc., it is characterized in that: the Welding Structure that is connected to of described acoustic vibration chamber 1 and public address section 2; After silencer 7 is housed on the acoustic vibration chamber 1, and muffler 8 before being equipped with on the public address section 2 all seals the part of acoustic wave soot blower outside stove or outside the container.The inner surface contour line of public address section 2 is a hyperbola, and its cross section is circular; The inner surface contour line of loudspeaker 3 is a hyperbola, and its cross section is designed to rectangle, and another kind of cross section is designed to circle; Before muffler 8 be cylindrical or square, interior filling sucting sound material 12 is as rock wool; After silencer 7 is cylindrical shape or square, inner liner stainless steel silk screen 10, and filling sucting sound material 11 is as industrial felt or rock wool therebetween.
