Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] Please refer to the attached Figures 1-5 , a white granulated sugar grading and screening device in an embodiment of the present utility model includes a housing 1, a feeding port 2 is connected to the top of the housing 1, and a screening mechanism 3 is arranged on one side of the feeding port 2;

[0031] The screening mechanism 3 includes a first screening mesh 31, a second screening mesh 32 and a third screening mesh 33. The aperture gradually becomes smaller from the first screening mesh 31, the second screening mesh 32 to the third screening mesh 33. Thus, the particles of the screened white granulated sugar gradually become smaller from top to bottom. Anti - slip rubber sleeves 37 are fixedly sleeved on the outer sides of the first screening mesh 31, the second screening mesh 32 and the third screening mesh 33. A plurality of anti - slip rubber wheels 34 are synchronously rotatably connected in the housing 1. The anti - slip rubber sleeves 37 cooperate with the anti - slip rubber wheels 34. Anti - slip patterns are arranged on the outer sides of the anti - slip rubber wheels 34 and the anti - slip rubber sleeves 37. When the anti - slip rubber wheels 34 rotate, they drive the anti - slip rubber sleeves 37 in contact with them to rotate synchronously through friction;

[0032] A plurality of limiting members 10 are fixedly connected inside the housing 1. Limiting rings 38 are fixedly connected to the outer sides of the first screening mesh 31, the second screening mesh 32, and the third screening mesh 33. The limiting rings 38 cooperate with the limiting members 10. A switch door 4 is rotatably connected to the outer side of the housing 1. A plurality of positioning members 12 are fixedly connected to the inner side of the switch door 4. The plurality of limiting members 10 and the positioning members 12 are both used to limit the limiting rings 38 and are respectively fixed at multiple positions of the plurality of limiting rings 38, and the angle between each position is 90 degrees. Thus, the anti-slip rubber sleeves 37 connected to the plurality of screening meshes can all be in mutual contact with the anti-slip rubber wheels 34, and the plurality of limiting members 10 and the positioning members 12 can support and guide the first screening mesh 31, the second screening mesh 32, and the third screening mesh 33, facilitating the improvement of the stability during their rotational screening;

[0033] A plurality of support plates 7 are fixedly connected inside the housing 1. A guiding groove 8 communicates with the middle of the support plate 7. The diameter of the guiding groove 8 gradually becomes smaller from top to bottom. Thus, the material can fall along the guiding groove 8 into the interior of the screening mesh below it for re-screening or be discharged through the discharge opening 9.

[0034] A discharge opening 9 is connected to the lower part of the housing 1. The discharge opening 9 is used for discharging fine impurities and powdered sugar, facilitating the ensuring of the purity of white granulated sugar, improving the screening quality, and the discharged fine impurities and powdered sugar can be processed and reused, reducing resource waste.

[0035] The plurality of support plates 7 and the guiding grooves 8 are respectively used to support and guide the first screening mesh 31, the second screening mesh 32, and the third screening mesh 33.

[0036] The switch door 4 is provided with a dust-proof net 5, facilitating the ventilation and air permeability of the interior of the housing 1. At the same time, the dust-proof net 5 can block external dust from entering. The positioning member 12 cooperates with the limiting ring 38, and the positioning member 12 has the same shape as the limiting member 10 and is both used to limit the limiting ring 38.

[0037] A controller 11 is fixed on one side of the housing 1. The controller 11 can control the operation of the screening mechanism 3. An observation window 6 is provided on the side of the housing 1 where the controller 11 is located, facilitating the real-time observation of the internal screening situation.

[0038] A motor 36 is fixedly connected to the top of the housing 1. The output end of the motor 36 is fixedly connected to a rotating shaft 35. The rotating shaft 35 extends into the housing 1 and is fixedly connected to a plurality of anti-slip rubber wheels 34.

[0039] Working principle: When in use, feeding is carried out into the interior of the housing 1 through the feeding port 2, and the feeding port 2 is located directly above the first screening mesh 31. Then, the motor 36 drives the rotating shaft 35 to drive a plurality of anti-slip rubber wheels 34 to rotate synchronously. As a result, the first screening mesh 31, the second screening mesh 32, and the third screening mesh 33 can perform screening synchronously. During screening, fine impurities and powdered sugar can be discharged from the housing 1 through the discharge port 9 for convenient centralized collection. After screening, when the switch door 4 is opened, the first screening mesh 31, the second screening mesh 32, and the third screening mesh 33 are only limited by the limiting members 10 on both sides. At this time, the first screening mesh 31, the second screening mesh 32, and the third screening mesh 33 can be sequentially extracted from between the limiting members 10 on both sides, which is convenient for timely cleaning and maintenance. At the same time, different aperture or specification sieves can be quickly replaced according to the changes in production requirements to achieve flexible grading and screening.

[0040] The above has described a specific embodiment of the present invention in detail, but the content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. Any equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
