[0024] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0025] See also Figure 1-6 The utility model provides a technical solution of an alumina screening device that can reduce water absorption:

[0026] Embodiment 1

[0027] An alumina screening device capable of reducing moisture absorption comprises a screening body 1 and a ton bag 2, wherein two discharge pipes 3 are fixedly connected to the surface of the screening body 1, a buffer bin 4 for feeding is arranged on the top of the screening body 1, the ton bag 2 corresponds to the discharge pipe 3, and an inner membrane 5 is fixedly connected to the interior of the ton bag 2, a sealing member is arranged on the surface of the discharge pipe 3, and the inner membrane 5 and the discharge pipe 3 are sealed by the sealing member.

[0028] A screen is arranged in the screening machine body 1, and two discharge pipes 3 are respectively located at the upper and lower sides of the screen.

[0029] The sealing member is a fixed disk 6 disposed at the bottom of the discharge pipe 3 . The diameter of the fixed disk 6 is larger than the diameter of the discharge pipe 3 . The inner film 5 is sleeved on the outside of the fixed disk 6 . The fixed disk 6 prevents the inner film 5 from being separated from the discharge pipe 3 .

[0030] Specifically, by eliminating the material silo and directly feeding into the buffer silo body 4, the process is reduced, the contact time between the material and the air is reduced, and by providing the inner membrane 5, the sealing of the ton bag 2 is improved, and the contact between the material in the ton bag 2 and the air is reduced. At the same time, the opening of the inner membrane 5 is connected to the discharge pipe 3 to reduce the contact between the material and the air during loading. When in use, the inner membrane 5 is put on the outside of the fixed plate 6 and the discharge pipe 3, and the inner membrane 5 and the discharge pipe 3 are tied with a rope to reduce the contact between the material and the air. Since the diameter of the fixed plate 6 is larger than the diameter of the discharge pipe 3, the fixed plate 6 is used here to prevent the inner membrane 5 from being separated from the discharge pipe 3 due to loosening of the rope.

[0031] Embodiment 2

[0032] In order to avoid the inconvenience of tying ropes, further, the upper surface of the fixed disk 6 is fixedly connected with an inner tube 7, the surface of the inner tube 7 is slidably connected to the inner wall of the discharge pipe 3, and the surface of the discharge pipe 3 is fixedly connected with a pressure plate 8, and the pressure plate 8 cooperates with the fixed disk 6 to clamp the inner film 5. By setting the pressure plate 8, when the fixed disk 6 and the pressure plate are close to each other, the two will clamp the inner film 5 located between them, and there is no need for tying ropes.

[0033] A locking piece 9 is fixedly connected to the surface of the pressing plate 8. The locking piece 9 is hook-shaped and made of elastic material. The locking piece 9 has a locking surface 10, and the locking surface 10 is in contact with the lower surface of the fixed disk 6. By setting the locking piece 9, the fixing disk 6 and the pressing plate 8 are locked after clamping the inner membrane 5.

[0034] A slider 11 is fixedly connected to the surface of the inner tube 7, a slide groove is provided on the inner wall of the discharge tube 3, and the slider 11 is slidably connected to the inner wall of the slide groove. The slide groove and the slider 11 are provided to prevent the inner tube 7 from being separated from the discharge tube 3.

[0035] A groove 12 is provided on the upper surface of the fixed disk 6, and a pressure strip 13 is fixedly connected to the lower surface of the pressure plate 8. The pressure strip 13 is adapted to the groove 12. By setting the pressure strip 13 and the groove 12, the degree of compression on the inner membrane 5 is increased to prevent it from detaching from the fixed disk 6. The pressure strip 13 can be a strip-shaped body with a triangular, trapezoidal or arc-shaped cross-section. In other embodiments, the pressure strip 13 can also be a plurality of annular bodies with different diameters, which can further prevent air from entering the inner membrane 5.

[0036] Working principle: When the alumina screening device that can reduce moisture absorption is used, the user first places the ton bag 2 at the position corresponding to the discharge pipe 3, and then puts the inner film 5 on the fixed plate 6, and makes the part of the inner film 5 higher than the fixed plate 6 fit on the upper surface of the fixed plate 6, and then pushes the fixed plate 6 upward, the fixed plate 6 squeezes the locking piece 9 and fits with the pressing plate 8. At this time, the fixed plate 6 and the pressing plate 8 are clamped by the inner film 5 when the pressure strip 13 and the groove 12 are matched, and the locking surface 10 fits with the lower surface of the fixed plate 6. The locking piece 9 locks the fixed plate 6 and the pressing plate 8. Then, the material is fed directly into the buffer bin body 4 and the screening body 1 is started to screen the material. The screened material falls into the ton bag 2 through the discharge pipe 3. By eliminating the silo and directly feeding into the buffer bin body 4, the process is reduced and the contact time between the material and the air is reduced. By setting the inner membrane 5, the sealing performance of the ton bag 2 is improved and the contact between the material in the ton bag 2 and the air is reduced. At the same time, the opening of the inner membrane 5 is connected to the discharge pipe 3 to reduce the contact between the material and the air during loading, so that the alumina screening device that can reduce moisture absorption can reduce the contact between the material and the air and reduce its absorption of moisture.

In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.
