Detailed Description

Referring to fig. 1-3, the present invention includes a box body 1, which is plate-shaped and has a chamber therein. The top of the box body is provided with two sets of mounting connecting pieces 9 for mounting the box body. The box comprises a first large-face side wall 2 and a second large-face side wall 3. The chambers include a showerhead chamber 5, a gap chamber 7, and a slit chamber 8. The nozzle cavity is communicated with the gap cavity, the gap cavity is communicated with the slit cavity, the width of the gap cavity is greatly smaller than that of the nozzle cavity, the width of the slit cavity is smaller than that of the gap cavity, the bottom surface of the slit cavity is a spraying narrow opening, and the width of the spraying narrow opening is 0.1-0.3 mm. The water mist is sprayed out from the spraying narrow opening to form a curtain shape. A plurality of water jet nozzles 4 are arranged on the side wall of the first large surface of the box body side by side and are connected with a water channel, the outlets of the water jet nozzles are cylindrical holes 4-1 and are connected with bell mouths 4-2, and the bell mouths are communicated with the spray head chamber. And a plurality of jet firing pins 6 are arranged on the second large side wall of the box body corresponding to the first large side wall, and each jet firing pin corresponds to one water jet nozzle. The jet firing pin is provided with a needle body 6-1, the needle body extends into a bell mouth of the water jet nozzle, and the diameter of the needle body is smaller than that of the cylindrical hole. The spray head chamber corresponds between the water jet spray head and the jet firing pin. The outer side surfaces of the lower parts of the first large-surface side wall and the second large-surface side wall are symmetrically inclined surfaces so as to reduce the appearance space of the box body. In the atomization dust-settling device structure, the water jet nozzle is introduced with high-pressure water, and the high-speed flowing water flow is strongly collided with the needle body when being sprayed out from the bell mouth to form tiny water drops; and then the water mist is broken into tiny particles through secondary collision of the gap chamber and tertiary collision of the slit-shaped chamber to form a water mist curtain which is sprayed out from the spraying narrow opening, so that the dust is efficiently suppressed in a dust control area. The water flow atomization process does not use an atomization nozzle, so that the faults caused by the blockage of the atomization nozzle are greatly reduced. The jet firing pin is in threaded connection with the second large-surface side wall, and the water jet nozzle is in threaded connection with the first large-surface side wall. The distance between the jet firing pin and the water jet nozzle can be adjusted according to the dust suppression requirement of the hydraulic press, and the size of the sprayed water mist granularity and the range of the water mist curtain can be changed by adjusting.

Fig. 3-7 show a second embodiment of the present invention, in which a separating plate 10 is disposed between a first large-side wall and a corresponding second large-side wall, the separating plate divides the gap chamber and the slit-shaped chamber into two parts with different widths, and the separating plate has through holes corresponding to the nozzle chamber and the gap chamber, so that water molecule particles can flow through the nozzle chamber and the gap chamber. The second embodiment divides the water mist entering the slit-shaped chamber into two parts by providing a dividing plate, and then discharges a double-layer water mist curtain from the double-mist-spraying narrow opening. Because the width of the two parts of the slit-shaped chamber and the width of the two outlets of the spraying narrow opening are different, the water mist curtains on each layer have different densities, larger particle dust and smaller particle dust can be respectively inhibited, and a better dust suppression effect is achieved.

Referring to fig. 6, an adjusting plate 11 is disposed between the first large-side wall and the second large-side wall, and the size and width of the nozzle chamber, the gap chamber, and the slit chamber can be adjusted by replacing the adjusting plates with different thicknesses, so as to meet different dust suppression requirements. The adjusting plate is provided with a sealing gasket for sealing.
