Example two
As shown in fig. 8, in a first comparative example, as another embodiment of the present invention, the cross-sectional shape of the second winding wheel 13 is a gourd shape, and the second winding wheel 13 is eccentrically arranged with respect to the central axis thereof; set up to calabash shape through the cross sectional shape with No. two take-up pulley 13, can make No. two take-up pulley 13 can drive No. two and connect the shake of rope 14 at the pivoted in-process, and the cooperation water drenches from No. two connection rope 14 surfaces down to improve the clearance effect of connecting rope 14 No. two.
A sliding groove 28 is formed in the second winding wheel 13; a counterweight ball 29 is connected in the sliding groove 28 in a sliding manner; through setting up spout 28 and counter weight ball 29, counter weight ball 29 can freely slide in spout 28, make No. two coiling wheels 13 at the pivoted in-process, counter weight ball 29 can be under the effect of self gravity, slide to other one end from the one end of spout 28, and then strike the 28 inner walls of spout, drive No. two coiling wheels 13 and produce the vibration, thereby make No. two connecting rope 14 further shake, shake off its surface adhesion's dyestuff, further avoid No. two dyestuff on connecting rope 14 to mix together with the dyestuff of newly adding, cause composition and the impure problem of colour.
The working principle is as follows: after the spray dryer is used, part of dye is easily adhered to the inner wall of the shell 1 of the spray dryer and needs to be cleaned manually at regular intervals, if the spray dryer is not cleaned in time, the dye on the inner wall of the shell 1 is mixed with newly added dye to cause impurities of components and colors, at the moment, the first connecting rope 10 can be loosened by controlling the motor 7 to rotate forwards, the first winding wheel 9 further rotates under the action of the torsion spring and winds the second connecting rope 14, the cleaning ring 11 is pulled to move downwards, then the motor 7 is controlled to rotate backwards, the first connecting rope 10 is wound by the first winding wheel 9, the cleaning ring 11 is pulled to move upwards, in the process that the cleaning ring 11 moves upwards and downwards, the steel wire layer 12 rubs and wipes the inner wall of the shell 1 in a rubbing mode so as to clean the dye remained on the inner wall of the shell 1 in the last working, and the self-cleaning function of the spray dryer is completed, the problem that the components and the color are not pure caused by mixing the dye on the inner wall of the shell 1 with the newly added dye is avoided; water flow is injected into the cleaning ring 11 through the water through port 15 and the hose 16 and finally sprayed out of the spray pipe 17, so that the cleaning ring 11 uniformly sprays water to the outside while moving up and down, residual dye on the inner wall of the shell 1 is softened, and the scraped dye flows out through the discharge port 5 along with the water flow by matching with the scraping action of the steel wire layer 12, so that the cleaning effect on the inner wall of the shell 1 is improved, and the problem that the dye is hard to clean due to drying on the inner wall of the shell 1 is avoided; the water flow enters the cleaning ring 11 from the hose 16, the floating blocks 18 and the floating rings 20 block the spray pipes 17, so that the water cannot flow out temporarily, when the water flow reaches the positions of the floating blocks 18, a pair of floating blocks 18 are pushed to compress the compression springs 19, at the moment, the floating blocks 18 drive all the floating rings 20 to slide in the cleaning ring 11 together through the connecting rods 21, all the spray pipes 17 are opened simultaneously, the water can flow out through the spray pipes 17, the operation can enable all the spray pipes 17 to spray water simultaneously, the water flow out of each spray pipe 17 is the same, and the problem that the partial cleaning of the inner wall of the shell 1 cannot be achieved due to the fact that the water flow of part of the spray pipes 17 is low is avoided; when water flows through the spray pipe 17, the spiral impeller 23 is pushed to rotate, the short shaft 22 drives the water wheel blades 24 to rotate together, the rotating water wheel blades 24 are in contact with the inner wall of the shell 1, a certain friction scraping effect is achieved, the cleaning degree of the inner wall of the shell 1 can be improved, meanwhile, when the water wheel blades 24 rotate, the water flows can be thrown to the periphery, and then the water flows penetrate into the steel wire layer 12 on the periphery, so that the water is distributed in the steel wire layer 12 more uniformly, and the uniform degree of cleaning of the inner wall of the shell 1 is improved; due to attraction between the first magnet 25 and the second magnet 26, when the water wheel blade 24 rotates, when the first magnet 25 and the second magnet 26 are close to each other, the second magnet 26 drives the surrounding steel wire layer 12 to approach towards the water wheel blade 24, so that the gap of the surrounding steel wire layer 12 is increased, and water flow can enter more conveniently, meanwhile, the water wheel blade 24 drives the surrounding steel wire layer 12 to shake through the second magnet 26, so that dyes entering the steel wire layer 12 can shake off, water flow can be rapidly diffused in the steel wire layer 12, water is further distributed in the steel wire layer 12 more uniformly, and the uniformity of cleaning the inner wall of the shell 1 is improved; when the spray dryer works, dye is possibly adhered to the second connecting rope 14, at the moment, the second connecting rope 14 is set to be a hollow structure, so that water in the cleaning ring 11 can flow into the second connecting rope 14 and flow outwards through the surrounding self-flowing holes 27, and then the water is sprayed to the lower end from the upper end of the second connecting rope 14 to clean the second connecting rope 14 per se, and the problem that the component and the color are not pure due to the fact that the dye on the second connecting rope 14 is mixed with the newly added dye is avoided; the section of the second winding wheel 13 is designed into a gourd shape, so that the second winding wheel 13 can drive the second connecting rope 14 to shake in the rotating process, and water is sprayed from the surface of the second connecting rope 14 in a matching manner, so that the cleaning effect of the second connecting rope 14 is improved; through setting up spout 28 and counter weight ball 29, counter weight ball 29 can freely slide in spout 28, make No. two coiling wheels 13 at the pivoted in-process, counter weight ball 29 can be under the effect of self gravity, slide to other one end from the one end of spout 28, and then strike the 28 inner walls of spout, drive No. two coiling wheels 13 and produce the vibration, thereby make No. two connecting rope 14 further shake, shake off its surface adhesion's dyestuff, further avoid No. two dyestuff on connecting rope 14 to mix together with the dyestuff of newly adding, cause composition and the impure problem of colour.
