Detailed Description

The embodiments of the present application will be described in detail in conjunction with the drawings in the embodiments of the present application, and it is obvious that the embodiments described are only a part of the embodiments of the present application, and not all of the embodiments.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "rear," and the like as used herein are for illustrative purposes only.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 to 3, the present invention provides a blower with humidification and flushing functions, which includes a blower main body and a spray pipe 6. The fan main body is used for supplying air. The spray pipe 6 is used for connecting an external water pipe to spray water columns on the fan main body.

The fan main body comprises a base 1, a transmission mechanism 2, a shell 3, an impeller 5 and a motor 8.

The motor 8 is arranged on the base 1. The motor 8 is connected with the impeller 5 through the transmission mechanism 2 to drive the impeller 5 to rotate.

The transmission mechanism 2 comprises a mounting seat and a transmission shaft which is rotatably arranged on the mounting seat. The mount pad is located base 1. The transmission shaft is connected with the impeller 5. The motor 8 is connected with the transmission shaft through a transmission belt to drive the impeller 5 to rotate.

It will be appreciated that in other embodiments the transmission 2 may be omitted and the motor 8 may be directly connected to the impeller 5.

The housing 3 includes a cylindrical main structure and a drain port connected to the main structure. The casing 3 covers the impeller 5. The housing 3 is larger in diameter than the impeller 5 so as not to interfere with the air supply of the impeller 5.

The dust and water adhered to the impeller 5 are thrown to the inner wall of the casing 3 by the centrifugal force along with the high-speed rotation of the impeller 5, and flow to the bottom of the casing along the inner wall of the casing 3.

The water outlet is arranged at the bottom of the shell 3 to flow out sewage.

Further, the water outlet is provided with a bottom valve 10 to control the opening and closing of the water outlet.

In one embodiment, the fan with humidification and flushing functions further comprises a filtering element for filtering the effluent sewage for recycling.

The shower pipe 6 is L-shaped. One end of the spray pipe 6 is used for connecting with the water inlet pipe, and the other end faces the impeller 5. The shower pipe 6 sprays water to the impeller 5 to perform washing, and the impeller 5 scatters and atomizes the water sprayed from the shower pipe 6 to perform humidification.

The peripheral wall of one end of the spray pipe 6 close to the impeller 5 is provided with a plurality of groups of small holes, each group of small holes are arranged at intervals along the axial direction of the spray pipe 6, and two adjacent groups of small holes are staggered along the circumferential direction of the spray pipe 6.

Preferably, the diameter of the small hole is 8mm, and the small hole is in a 360-degree radiation state. The 360-degree radiation state means that the small holes are densely distributed along the circumferential direction of the spray pipe 6 and completely cover all angles.

The arrangement of the positions of the small holes enables the water spraying coverage to be more uniform without dead angles.

The fine water columns sprayed from the spray pipe 6 in all directions contact and collide with the impeller 5 rotating at high speed, and then are scattered and atomized. In the process, firstly, dust attached to the impeller 5 can be contacted with the water column, and the whole impeller 5 can be washed clean under the double compound motion state of the linear motion of the water column and the high-speed rotation of the impeller 5.

The sprayed water column is scattered and atomized, and the dust-containing gas is subjected to primary pre-dedusting treatment, so that the load of a subsequent deduster is reduced, and the dedusting efficiency can be improved to a greater extent. Meanwhile, the dust-containing gas can be humidified, and the requirement of humidifying the dust-containing gas in certain process requirements is met.

In the illustrated embodiment, the blower with humidification and flushing functions further comprises an inlet horn 9 and an inlet straight section 4.

The smaller diameter end of the inlet horn 9 is fixed on the fan main body, and the inlet horn 9 and the impeller 5 are arranged oppositely.

Specifically, the inlet horn 9 is fixed to a fixing frame outside the impeller 5.

The inlet straight section 4 is fixed at the end with larger diameter of the inlet horn 9, and one end of the spray pipe 6 is arranged in the inlet straight section 4 in a penetrating way.

One end of the spray pipe 6 close to the impeller 5 is coaxial with the impeller 5 and is arranged at intervals with the impeller 5. And the other end of the impeller 5 is provided with a flange connector to be connected with an external water pipe.

The spray pipe 6 is made of a thick-wall steel pipe made of stainless steel, the spray pipe 6 which is cantilevered is guaranteed to have enough strength and rigidity, the spray pipe 6 cannot be warped downwards even after being used for a long time, the spray pipe 6 cannot be in contact with the impeller, and safety can be guaranteed.

In addition, those skilled in the art should recognize that the above embodiments are illustrative only, and should not be taken as limiting, and that suitable changes and modifications can be made within the spirit and scope of the present disclosure.
