The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. 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. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in figure 1, the utility model provides a spray dryer, which comprises a dryer body 1, a rotating shaft 2 is rotatably connected at the lower end inside the dryer body 1, a motor 9 is arranged below the dryer body 1, the output end of the motor 9 is coaxially fixedly connected with the rotating shaft 2, a plurality of support arms 3 are fixedly connected at the peripheral side of the upper end of the rotating shaft 2, in the embodiment, the support arms 3 are arranged in two and are distributed in a circumferential array at equal intervals by the axis of the rotating shaft 2, a scraper 4 is vertically fixedly connected at the upper end surface of one end of the support arm 3 far away from the rotating shaft 2, the scraper 4 is abutted against the inner wall of the dryer, all set up the water guide way of mutual intercommunication in support arm 3 and the scraper blade 4, 1 lower extreme of desiccator body is provided with the rotary joint 5 that the rigid coupling just communicates with the water guide way on pivot 2, and rotary joint 5 intercommunication has wash pipe 6, sets up a plurality of directional adjacent through-holes 7 that 1 inner wall of desiccator body just communicate with the water guide way on the scraper blade 4.
