Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail with reference to fig. 1 to 6.

As shown in fig. 1 and 2, a foam nozzle for dust fall includes: the device comprises a base 1, a rotator 2, a spray body 3 and a cover body 4; a fixing hole 1-1, an external thread joint 1-2 and a channel 1-3 are arranged on a disc-shaped base 1.

As shown in fig. 5 and 6, the upper part of the rotator 2 is a cylindrical rotating body 2-1, and two columns 2-2 opposite to each other are arranged on the outer wall of the rotating body 2-1; the inner wall of the rotating main body 2-1 is uniformly provided with rotating plates 2-3 with horizontal included angles.

As shown in fig. 3 and 4, the upper part of the spray body 3 is a hollow hemispheroidal nozzle 3-1, and the top of the nozzle 3-1 is provided with a long spray seam 3-2; the lower part of the spray body 3 is a cylindrical bearing body 3-3, and the outer diameter of the bearing body 3-3 is smaller than the outer spherical diameter of the spray nozzle 3-1; the inner wall of the bearing body 3-3 is provided with two long grooves 3-4 which are arranged along the axial direction of the bearing body 3-3 and are opposite in position; 3 or 4 supporting blocks 3-5 are uniformly arranged on the outer wall of the lower end of the bearing body 3-3 in the circumferential direction; the wall of the bearing body 3-3 is provided with a plurality of through holes 3-6.

As shown in fig. 1, the cover body 4 is cylindrical, an internal thread joint 4-1 is arranged at the lower part of the cover body, and the internal thread joint 4-1 is matched with an external thread joint 1-2; an accommodating cavity 4-2 is formed in the middle and upper inner parts of the cover body 4, and the diameter of the accommodating cavity 4-2 is smaller than the minimum thread diameter of the internal thread joint 4-1; the diameter of the inner wall of the upper part of the cover body 4 is gradually reduced along with approaching to the upper end of the cover body 4 to form an arc curved surface 4-3; the upper end edge of the containing cavity 4-2 is a ring opening 4-4.

The outer side surface of the supporting block 3-5 and the outer spherical surface of the nozzle 3-1 are respectively matched with corresponding parts of the inner wall of the cover body 4, so that the spray body 3 can smoothly and stably rotate along the central shaft in the accommodating cavity 4-2.

The use principle is as follows: inserting a stand column 2-2 of a rotator 2 into a spraying body 3 along an elongated slot 3-4, then inserting the spraying body 3 into a cover body 4, and screwing the cover body 4 on a base 1 to form a dust settling foam nozzle; the spray head is connected with the foam conveying pipeline through the fixing hole 1-1 by a bolt. When the valve is opened, the foam impacts along the channel 1-3 under the action of pressure and passes through the rotator 2 to enter the accommodating cavity 4-2, and is ejected out of the long spray seam 3-2 in a sector shape. Meanwhile, the foam enters a gap between the bearing body 3-3 and the cover body 4 through the through hole 3-6, and pushes the nozzle 3-1 to be tightly attached to the arc curved surface 4-3 of the cover body 4 under the action of foam pressure to form a sealing curved surface so as to prevent the foam from leaking. The foam impact rotating plate 2-3 drives the rotator 2 and the spraying body 3 to rotate, so that the sector-shaped foam sprayed from the spraying seam 3-2 is sprayed in a rotating manner, and the dust removal effect is better.

The supporting block 3-5 can stabilize the lower end (the other end opposite to the spray seam 3-2) of the spray body 3 without deviation, so that the spray body 3 rotates around the axis stably, the failure rate can be reduced, and the dust settling effect is improved.
