Example Embodiment

[0016] Example 1:

[0017] like figure 1 As shown, the drying and dispersing equipment for wet powder includes a drying cylinder 1, a plurality of sieve plates 2 and an anti-settling rotating assembly 3. The drying cylinder 1 includes a cylinder body 11 with both upper and lower ends open, and is fixed to the cylinder. The top cover 12 on the upper end face of the body 11, the cylinder bottom 13 fixed on the lower end face of the cylinder body 11, the lower part of the side wall of the cylinder body 11 is provided with a feed port 14 which penetrates the inner and outer walls of the side wall, and the top cover 12 is provided with a feed port 14 which penetrates the upper and lower sides of the cylinder body 11. The discharge port 16 on the end face, the anti-sinking rotating assembly 3 includes a rotating rod 31 that can rotate along the axis, a connecting plate 32 fixedly connected to the circumferential surface of the rotating rod 31, a scraper 33 fixedly connected to the l...

Example Embodiment

[0019] Example 2

[0020] This embodiment makes the following further limitation on the basis of Embodiment 1: the sieve plate 2 includes an upper sieve plate 22, a middle sieve plate 23, and a lower sieve plate 24 longitudinally distributed from top to bottom, and the lower sieve plate 24 Located above the feed port 14 . In this embodiment, the lower sieve plate 24 is located above the feeding port 14, so that the agglomerated wet material deposited on the bottom of the cylinder 13 is dried by the hot air at the feeding port 14 through the anti-settling rotating component 3 and moves upward with the air flow.

Example Embodiment

[0021] Example 3

[0022] This embodiment makes the following further limitation on the basis of Embodiment 1: in the plurality of sieve plates 2, the distance between every two adjacent sieve plates 2 from the top to the bottom gradually decreases. In this example, because the aperture of the sieve hole 21 on the middle sieve plate 23 is relatively larger than the hole diameter of the sieve hole 21 on the upper sieve plate 22, the material is easy to pass through the middle sieve plate 23 under the action of the hot air flow and the air flow of the induced draft fan, but is not easy to pass through the upper sieve plate 22. Sieve plate 22. At this time, the material is likely to stay in the area between the middle sieve plate 23 and the upper sieve plate 22. In order to avoid clogging, the distance between the lower sieve plate 24 and the middle sieve plate 23 is smaller than the distance between the middle sieve plate 22 and the upper sieve plate 22. .

Abstract

The invention discloses a drying and dispersing device for wet powder materials. The device comprises a drying cylinder, multiple screening plates and an anti-settling rotary assembly. The drying cylinder comprises a cylinder body, a top cover and a cylinder bottom, a feed inlet is formed in the lower portion of the side wall of the cylinder body, and a discharging opening is formed in the top cover. The anti-settling rotary assembly comprises a rotary rod, a connecting plate, a scraper and a rotation driving element, the rotary rod penetrates through the cylinder body or the two side walls of the cylinder bottom and is arranged below the feed inlet, the rotation driving element is fixedly connected with the end of the rotary rod and arranged on the outer side of the cylinder body or the outer side of the cylinder bottom, the lower end face of the connecting plate are matched with the upper end face of the cylinder bottom, the screening plates are transversely arranged in the cylinder body and are longitudinally distributed along the axis of the cylinder body, the screening plates are provided with a plurality of screening holes penetrating through the upper end faces and the lower end faces of the screening plates, and according to every two adjacent screening plates, the aperture of the screening holes in the lower screening plate is larger than that of the screening holes in the upper screening plate. The drying and dispersing device overcomes the defects of an existing flash dryer, and has the advantages of being good in drying performance, high in reliability and low in cost.

Description

technical field [0001] The invention relates to the field of airflow dryers, in particular to drying and dispersing equipment for wet powder materials. Background technique [0002] The airflow dryer has the advantages of high drying strength, large processing capacity, and simple equipment, and has been widely used in the pharmaceutical, food, and chemical industries. However, when the airflow dryer is used to dry wet powder, because the wet powder is easy to agglomerate, it is not conducive to being completely dried during the working process, which not only affects the dryness of the powder, but also is not conducive to being airflow It is carried away and enriched in the drying cylinder, which eventually leads to tower blockage and even fire accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of the above-mentioned existing air dryer, and to provide drying and dispersing equipment for wet powder. [0004] T...
