Problems solved by technology
This technical solution uses a louver-type adjustment mechanism to adjust and adjust the wind direction of the fan. The adjustment range of this technical solution is not enough, the change of the wind direction rotation direction is not large enough, and the cooling effect is not good, so further improvement is needed

Embodiment Construction
[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other; the present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0020] refer to figure 1 , 2 :
[0021] A negative pressure blower for cooling and dust removal proposed by the present invention includes a driving mechanism 1, a fan blade 2, a casing 3, and an atomizing mechanism. The driving mechanism 1 drives the fan blade 2 to rotate through a transmission shaft 4;
[0022] The atomizing mechanism includes a rotating part 5 and a water pump 6. The rotating part 5 is installed on the transmission shaft 4. The rotating part 5 is connected to the transmission shaft 4 in rotation. The rotating part 5 is provided with a first medium storage space 8. The rotating part 5 The member 5 is provided with a number of first spray holes 7 c...

The invention discloses a negative-pressure draught fan for cooling and dust removing. The negative-pressure draught fan comprises a drive mechanism, fan blades, a shell and an atomization mechanism. The drive mechanism drives the fan blades to rotate through a transmission shaft. The atomization mechanism comprises a rotation piece and a water pump. The rotation piece is arranged on the transmission shaft and is rotationally connected with the transmission shaft. The rotation piece is provided with a first medium storage space. The rotation piece is provided with a plurality of first atomizing holes communicating with the first medium storage space. The hole diameter of the first atomizing holes is 0.1mm-1mm. The first medium storage space communicates with the water pump through a pipeline. According to the negative-pressure draught fan, water mist is generated through the atomizing mechanism, the water mist and water are sufficiently combined, and therefore the dust removing and cooling effects are obvious. Ventilation within a certain range can be achieved according to needs, long-distance ventilation is achieved, the wind direction can be flexibly adjusted, the adjusting amplitude is large, the using effect is better, the structure is simple, and using is convenient.
Description
technical field [0001] The invention relates to the technical field of fans, in particular to a negative pressure fan used for cooling and dust removal. Background technique [0002] The negative pressure fan uses the cooling principle of air convection and negative pressure ventilation. It is a kind of natural inhalation of fresh air from the opposite side of the installation site --- the door or window, and the indoor sultry gas is quickly forced out of the room. Any poor ventilation problems will be eliminated. It can be improved, and the effect of cooling and ventilating can reach 90%-97%. [0003] The existing negative pressure fans are basically installed on the wall, which is far away from the workers in the workshop, and the wind direction of the existing negative pressure fans cannot be adjusted, and the position cannot be moved; large equipment in the workshop It is easy to block the wind. In some special workshops, it is only necessary to cool down the workers an...
