[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] refer to Figure 1-4 This utility model provides the following two technical solutions:

[0026] First embodiment: A crystal dehydration centrifugation device for nano-fluorescent whitening agents includes a housing 1, and a dehydration component for dehydrating nano-fluorescent whitening agent crystals connected to the housing 1. The dehydration component includes: a barrier 2, installed on the left side of the housing 1 for preventing crystals from detaching; and a centrifugation component 3, installed on the housing 1 for centrifugal dehydration of the crystals. The centrifugation component 3 includes a centrifuge cylinder 31 rotatably connected inside the housing 1. A drive component 32 for driving the centrifuge cylinder 31 to rotate is installed on the right side of the housing 1. A cylinder 33 is fixedly connected to the right side of the housing 1. A spray plate 34 that fits against the inner wall of the centrifuge cylinder 31 is fixedly connected to the extended end on the left side of the cylinder 33. A corrugated pipe 35 that is fixedly connected to the housing 1 is fixedly connected to the middle right side of the spray plate 34. A branch pipe 36 is fixedly connected to the right side of the corrugated pipe 35 near the outer end of the housing 1. A spray strip 37 is fixedly connected to the upper side of the housing 1 near the top of the centrifuge cylinder 31. A three-way valve 38 that is fixedly connected to the upper end of the spray strip 37 and the branch pipe 36 is fixedly connected to the upper side of the three-way valve 38. A conduit 39 is fixedly connected to the upper side of the three-way valve 38.

[0027] Air compressor 4 is fixedly connected to the top of housing 1 and its outlet end is fixedly connected to conduit 39; solenoid valve 5 is fixedly connected to the bottom of housing 1 for dewatering and discharge; recovery box 6 is slidably connected to the left side of housing 1 and located at the lower end of barrier 2; drive unit 32 includes a second motor 321 fixedly connected to the right side of housing 1, a gear 322 is coaxially fixedly connected to the left side of the second motor 321, and a gear ring 323 that meshes with the gear 322 is coaxially fixedly connected to the right side of centrifuge cylinder 31; centrifuge cylinder 31 is provided with several filter holes for centrifuged water discharge near the left side of spray plate 34, and several spray holes are provided on the left side of spray plate 34. The inside of spray plate 34 is hollow and communicates with corrugated pipe 35 and spray holes respectively;

[0028] The edge of the spray plate 34 is attached to the inner wall of the centrifuge cylinder 31. The left side of the housing 1 near the centrifuge cylinder 31 has a feed inlet. The upper side of the housing 1 near the centrifuge cylinder 31 has a slot that communicates with the spray bar 37. The spray bar 37 is hollow inside and has several air jet holes at the bottom. The lower side of the housing 1 near the centrifuge cylinder 31 has a storage slot that communicates with the solenoid valve 5. The bottom of the solenoid valve 5 is fixedly connected to a drain pipe. When the second motor 321, gear 322, and gear ring 323 cooperate to rotate the centrifuge cylinder 31, the air compressor 4, conduit 39, three-way valve 38, and spray bar 37 cooperate to clear the filter holes inside the centrifuge cylinder 31. The cylinder 33 and spray plate 34 cooperate to have the function of exporting crystals from the centrifuge cylinder 31. The three-way valve 38 is reversed. At this time, compressed air is sprayed out through the branch pipe 36, bellows 35, and spray plate 34 to promote the removal of residual material attached to the spray plate 34.

[0029] The main difference between the second implementation method and the first implementation method is that:

[0030] The barrier 2 includes two sets of baffles 24 slidably connected to the left side of the housing 1. Two sets of connecting frames 23 are fixedly connected to the two sets of baffles 24 away from the middle of the housing 1. A first motor 21 is fixedly connected to the rear top of the housing 1. A bidirectional screw 22 that is rotatably connected to the output end of the first motor 21 is coaxially fixedly connected to the housing 1. The bidirectional screw 22 is threadedly connected to the two sets of connecting frames 23 respectively. By cooperating with the first motor 21 and the bidirectional screw 22, the horizontal position of the two sets of connecting frames 23 and the baffles 24 is adjusted to control the opening state of the left feed port of the centrifuge cylinder 31.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user introduces the desired dehydrated nano-fluorescent brightening agent crystals into the centrifuge drum 31 through the feed inlet on the left side of the housing 1. The first motor 21 is then started. The first motor 21 adjusts the horizontal positions of the two sets of connecting frames 23 and baffles 24 via a bidirectional screw 22, causing the two sets of baffles 24 to close the feed inlet on the left side of the housing 1. The second motor 321 is then started, driving the gear 322 to rotate. The rotating gear 322 drives the centrifuge drum 31 to rotate via a gear ring 323. The rotating centrifuge drum 31 centrifuges and dehydrates the nano-fluorescent brightening agent crystals. The dehydrated water is then introduced into a temporary storage tank on the lower side of the housing 1 through the filter holes on the centrifuge drum 31. During this process, the air compressor 4 is started, drawing in outside air and... The compressed air is then sprayed out onto the outside of the rotating centrifuge drum 31 through the three-way valve 38 and the spray bar 37. The compressed air clears the filter holes inside the centrifuge drum 31. After the centrifugation operation is completed, the second motor 321 is turned off, and the three-way valve 38 is reversed. At this time, the compressed air is sprayed out through the branch pipe 36, the bellows 35, and several spray holes on the left side of the spray plate 34. The compressed air sprayed out of the spray holes promotes the removal of residual material adhering to the surface of the spray plate 34. Then the air compressor 4 is turned off, and the barrier 2 is opened. The horizontal position of the spray plate 34 is adjusted by the cylinder 33. The spray plate 34 pushes the nano fluorescent whitening agent crystals retained in the centrifuge drum 31 to the left, pushing the nano fluorescent whitening agent crystals out of the centrifuge drum 31 and into the recovery box 6.
