Automatic rotating nozzle and adjustment method of nozzle rotating speed

Abstract

The invention discloses an automatic rotating nozzle and an adjustment method of a nozzle rotating speed. The automatic rotating nozzle comprises an outer cover and a blowing mouth; the blowing mouth is in a bowl-shaped structure with the bottom opened; an opening is formed in the top of the outer cover; and the blowing mouth is placed in the top opening of the outer cover. The automatic rotating nozzle further comprises a main rotating body, a slave rotating body, a blade adjustment device and a rear seat; the slave rotating body is placed between the top opening of the outer cover and the blowing mouth; a top opening of the slave rotating body and the outer side of the main rotating body are fixed by a fastener; a bearing rod is arranged at the axis center of the main rotating body; a bearing support is arranged at the center of the top of the rear seat; at least one bearing is placed in the bearing support; the bearing rod penetrates through the bearings; and the blade adjustment device is fixed below the main rotating body. The extension and contraction of blades are controlled through the blade adjustment device, so that the purpose of controlling a rotating speed to be best during blowing spraying of the automatic rotating nozzle is achieved.

Description

technical field [0001] The invention relates to the field of air purification and dust removal devices, in particular to an automatic rotating nozzle and a method for adjusting the rotational speed of the nozzle. Background technique [0002] Nozzles are mainly used in air shower rooms, air shower transfer windows and other air purification equipment terminals. The nozzles in the prior art generally achieve the shower effect by manually adjusting the angle of the nozzle, which cannot be automatically rotated. The blowing surface is fixed and difficult to adjust. The dust particles on the surface of objects from all angles are not completely removed, and the dust particles are easily brought into the clean room with people or goods, thus affecting the cleanliness of the clean room.

[0002] Nozzles are mainly used in air shower rooms, air shower transfer windows and other air purification equipment terminals. The nozzles in the prior art generally achieve the shower effect by manually adjusting the angle of the nozzle, which cannot be automatically rotated. The blowing surface is fixed and difficult to adjust. The dust particles on the surface of objects from all angles are not completely removed, and the dust particles are easily brought into the clean room with people or goods, thus affecting the cleanliness of the clean room

[0003] Chinese patent No. 2013100678231 discloses a 360 o The automatic rotating nozzle, the patent is by deflecting the angle of the blade, increasing or reducing the force area of ​​the air circulation to adapt to the working speed under different air volume environments; If it does not rotate, the blowing will not be complete. When the blade angle is adjusted too large, the speed will be too fast, which will cause the blown wind to disperse easily, and the blowing distance will not meet the requirements, resulting in unsatisfactory dust removal effect; because the rotating nozzle is often installed in the blowing In the channel of the shower room, when the worker's finger touches the blade, the angle of the blade will change, and the air volume and speed of the nozzle may not meet the spraying requirements.
