Detailed description of the invention

In order to make those skilled in the art be better understood from this utility model scheme, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clear, complete description.

As Figure 1-3, a kind of can the warm-air drier of catch blowing sand, including casing 1, Power Component 2, draught fan impeller 3, rotating shaft 4 and for preventing dust storm from entering the sand assembly 5 in blower fan.Described sand assembly 5 can prevent sand and dust from entering in blower fan.Concrete, described casing 1 is provided with air inlet 11 and air outlet 12, and described sand assembly 5 includes that windshield 51 and inlet air orifice, described windshield 51 cover at described shell air inlet 11, stop the dust storm at fan inlet.This inlet air orifice is opened on windshield 51；Concrete, described inlet air orifice includes the annular hole slot 52 that at least four groups are offered along windshield 51 circumference, and with the present embodiment, described annular hole slot 52 is set to 4.The diameter of this annular hole slot 52 is arranged in being gradually incremented by；I.e. the closer to the center of circle of windshield, the diameter of this annular hole slot 52 is the least.Described annular hole slot 52 all includes some circular hole grooves 521, and these circular hole grooves 521 are incline structure from top to bottom and arrange, by casing internal be connected externally to lead to.And owing to circular hole groove 521 is for being obliquely installed so that dust storm is more not easily accessible blower fan.As preferably, the angle of inclination of described circular hole groove 521 is set to 45 °.

In order to more preferable catch blowing sand enters, we are externally connected with sandboard 8 at described annular hole slot 52.Concrete, the top of described each annular hole slot 52 is provided with link slot, is then fixedly connected with a contiguous block in the end of sandboard.When contiguous block coordinates clamping with described link slot, sandboard has just been connected on windshield.

Described heating member 9 is then arranged on to be located on rear side of described motor 22, i.e. position at air outlet.Concrete, heating member 9 includes the first vertical-shaped heat pipes the 91, first helical heating pipe 92 and the second helical heating pipe 93, described first helical heating pipe 92 is arranged on front side of the first vertical-shaped heat pipes 91, and described second helical heating pipe 93 is arranged on rear side of the first vertical-shaped heat pipes 91.When wind passes in and out from the air outlet of blower fan, first pass through the first helical heating pipe 92 and heat, heated by the first vertical-shaped heat pipes 91 afterwards, after eventually passing the second helical heating pipe 93 heating, reach blowout.Add with each and contact between heat pipe fully, being brought rapidly up in the short time can be realized.

In order to make the more preferable driven described draught fan impeller of motor, we are provided with the first connection protuberance 6 in described motor 22 side, correspondence, are provided with the second connection protuberance 7 at described draught fan impeller 3 sidepiece.Described first connection protuberance 6 is provided with and is available for the first connecting groove 61 that rotating shaft 4 snaps in；This second connection protuberance 7 described is provided with and is available for the second connecting groove 71 that rotating shaft 3 snaps in；It is spline between described rotating shaft 3 with described first connecting groove 61 and the second connecting groove 71 to coordinate, thus when motor-driven rotatable shaft rotates, draught fan impeller together can rotate with rotating shaft, and both are connected firmly.

Described draught fan impeller 3 is placed in casing 1, and described Power Component 2 includes that casing 21 and motor 22, described motor 22 are placed in described casing 21；Windshield 51 it is covered with at described air inlet, the connection limit 511 that this windshield 51 sidepiece is formed with a inwardly extending, described casing is provided with snap flange 111 by 1 nearly air inlet 11 side sidewall, and this snap flange 111 is provided with and can be connected the engaging annular groove 112 that limit 511 coordinates with this.

Further, being additionally provided with four lower margins 10 in the bottom of casing, described ground sole 10 is set to crash roll.The setting of four lower margins 10 so that landing of blower fan is more stable, and the bottom of lower margin 10 is provided with crash roll, can alleviate noise during blower fan work.

Obviously, described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.
