DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] like Figure 1 and Figure 2The liquid sprayer shown in the figure comprises a feed barrel 1, a quantitative liquid separation mechanism 2 and a spray head 3. A feed pipe 11 is connected to the side wall of the feed barrel 1, and the feed pipe 11 is connected to an infusion pump 4. The infusion pump 4 can continuously input dye liquid into the feed pipe 11. Excessive dye liquid input will affect the thermal drying effect (excessive input of dye liquid will make the spraying amount too large, resulting in too many droplets, and the hot air drying will not be in time, which will cause the drying effect to deteriorate and cause the problem of high water content in the product). Therefore, in order to ensure the drying quality, the utility model is designed with a quantitative liquid separation mechanism 2. The liquid mechanism 2 is used to cooperate with the controlled amount of liquid feeding. The quantitative liquid dispensing mechanism 2 includes a rotating shaft 21 and a dispensing seat 22. The rotating shaft 21 is upright and rotatably installed in the feeding barrel 1. The dispensing seat 22 is fixedly connected to the rotating shaft 21. The dispensing seat 22 can rotate with the rotating shaft 21. A first notch 221 is provided on the dispensing seat 22. During the rotation of the dispensing seat 22, the liquid input by the feeding pipe 11 can be intermittently and quantitatively received (only when the first notch 221 is rotated to be opposite to the feeding pipe 11, the dye liquid in the feeding pipe 11 can enter the first notch 221. The first notch 221 determines the amount of liquid input each time. The input amount of the feed), the spray head 3 is rotatably installed under the feed barrel 1, the spray head 3 is connected to the feed barrel 1, the spray head 3 is provided with an inner cavity, the material liquid received by the material distribution seat 22 can fall into the spray head 3, the rotating shaft 21 is fixedly connected to the spray head 3, and the spray head 3 can be driven by the rotating shaft 21 to rotate at a high speed. A plurality of liquid outlet holes 31 are provided on the outer wall of the spray head 3. The dye liquid falling into the inner cavity of the spray head 3 will be centrifugally thrown out from the liquid outlet hole 31 position when the spray head 3 rotates at a high speed, forming a spraying effect. The outer wall of the feed barrel 1 of the utility model is fixedly connected A flange 12 is connected, and the present invention can be fixedly installed on the spray drying equipment through the flange 12. The present invention is installed on the top of the spray drying equipment, spraying droplets from top to bottom, and forming drying hot air from bottom to top in the spray drying equipment. The spraying effect of the present invention can make the dye liquid dispersed into droplets very well, and the diffusion area of the droplets is wide, which can fully contact with the upwelling drying hot air. Drying and dehydration can be completed in a few seconds, and finally a dry dye powder product is obtained. The present invention can cooperate well to complete the drying operation of the dye product.
[0021] like Figure 2 As shown, the outer diameter of the material distribution seat 22 matches the inner cavity size of the feed barrel 1. During the rotation of the material distribution seat 22, only when the first notch 221 rotates to be opposite to the feed pipe 11, the dye liquid in the feed pipe 11 can enter the first notch 221. In other cases, the outer wall of the material distribution seat 22 forms a blocking effect on the feed pipe 11, and the feed pipe 11 cannot input liquid into the feed barrel 1. Therefore, the rotation of the material distribution seat 22 can form a positioning liquid feeding effect, and the size of the first notch 221 determines the input amount of each feed.
[0022] like Figure 2As shown, the quantitative liquid dispensing mechanism 2 also includes a partition plate 23, which is fixedly connected to the feeding barrel 1, and the lower end surface of the material dispensing seat 22 contacts the partition plate 23, and a second notch 231 is provided on the partition plate 23. Since the partition plate 23 is fixed, the position of the second notch 231 is also fixed, and the plate surface of the partition plate 23 can form a bottom sealing effect on the first notch 221 of the material dispensing seat 22. As the material dispensing seat 22 rotates, the first notch 221 will rotate to the position of the second notch 231. At this time, the first notch 221 and the second notch 231 coincide with each other and are connected, and the bottom of the first notch 221 will form an open state, and the material liquid in the first notch 221 can fall and pour through the second notch 231. The upper end of the spray head 3 is rotatably connected to the outer wall of the feeding barrel 1, and the bottom of the feeding barrel 1 is open. The bottom part of the feeding barrel 1 is inserted into the spray head 3, and the material is dispensed from the first notch 221 to the second notch 231. The liquid falling from the two notches 231 will enter the inner cavity of the spray head 3, and the bottom end of the rotating shaft 21 extends and is inserted into the spray head 3, and is fixedly connected to the bottom of the inner cavity of the spray head 3. As the rotating shaft 21 rotates, a synchronous rotation effect of the spray head 3 can be formed. After the spray head 3 rotates, the liquid inside it can be centrifugally thrown out to form a spraying effect. Due to the existence of the quantitative liquid separation mechanism 2, the amount of liquid entering the spray head 3 each time is controlled, and the spray head 3 can form an effect of intermittent spraying of droplets. Under this effect, the load of hot air drying can be reduced to ensure the drying quality of the product. The quantitative liquid separation mechanism 2 also includes a motor 24. The motor 24 is installed on the top of the feed barrel 1, and the output end of the motor 24 is connected to the rotating shaft 21. After the motor 24 is started, it can continuously drive the rotating shaft 21 to rotate, so as to form the effect of quantitative liquid separation in the feed barrel 1 and continuous centrifugal sprinkling of liquid by the spray head 3.
[0023] like Figure 2 As shown, a tapered portion 32 is formed at the lower end of the spray head 3. The tapered portion 32 can automatically concentrate the liquid falling into the spray head 3 into the inner cavity of the tapered portion 32. The liquid outlet holes 31 are all opened on the side wall of the tapered portion 32. The liquid outlet holes 31 are opened in two circles, upper and lower, along the side wall of the tapered portion 32. The liquid outlet holes 31 are connected to the inner cavity of the tapered portion 32. When the spray head 3 rotates, droplets are sprinkled out from the liquid outlet holes 31. The upper circle of liquid outlet holes 31 takes effect when the liquid volume is large, and the lower circle of liquid outlet holes 31 can always take effect to sprinkle droplets. Since the droplets are sprinkled centrifugally, the spray coverage area of the droplets will be relatively wide, and the droplets are relatively dispersed, which facilitates the droplets to fully contact with the drying hot air. In actual production, it is found that the droplets can be dried within a few seconds of falling.
[0024] like Figure 2As shown, the spraying head 3 is provided with a wall scraping plate 25, the wall scraping plate 25 contacts the inner wall of the conical part 32, the wall scraping plate 25 is connected with a plate handle 251, the upper end of the plate handle 251 is fixedly connected to the lower end surface of the partition plate 23, the wall scraping plate 25 is two in number and is symmetrically installed, the wall scraping plate 25 is fixedly installed, but the spraying head 3 can rotate, in the rotating process of the spraying head 3, the wall scraping plate 25 forms a wall scraping effect on the inner wall of the conical part 32, so as to reduce the plugging condition at the position of the liquid outlet small hole 31, the wall scraping plate 25 can also push the material liquid to move, so that the material liquid is smoothly thrown out from each liquid outlet small hole 31, the above design can effectively reduce the failure rate of the spraying head 3 and reduce the maintenance burden.
[0025] The preferred embodiments of the present application have been described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical scheme falling within the idea of the present application belongs to the protection scope of the present application.
