Embodiment Construction
[0009] In the following, the specific implementation manners of the present invention will be further described in detail in conjunction with the accompanying drawings of the embodiments, so as to make the technical solution of the present invention easier to understand and grasp.
[0010] Such as figure 1 As shown, the drying device for DHPPA particularly includes a double-cone rotary drying unit and a heat supply unit 7 , and the double-cone rotary drying unit includes a support 1 , a motor 11 and a rotary drying cabin 2 . The two sides of the rotary drying cabin 2 are airtight containers with double cones. The double-cone shaft of the rotary drying cabin is connected to the support 1, and the motor 11 is fixed on the support 1 and drives the rotary drying cabin 2 to rotate axially. The rotary drying cabin 2 is provided with a heat supply circulation pipeline 3, a material inlet 4, a discharge opening 5 and a through opening 6, wherein the heat supply circulation pipeline 3...

The invention discloses a drying device used for DHPPA. The drying device comprises a two-cone rotation drying unit and a heat supply unit, wherein the two-cone rotation drying unit comprises a support, a motor and a rotation drying cabin provided with two cones, the two cones of the rotation drying cabin are coupled with the support, the rotation drying cabin is provided with a heat supply circulating pipeline, a feed port, a discharge port and a through hole, the heat supply circulating pipeline is positioned on the inner wall of the rotation drying cabin, the pipeline port of the heat supply circulating pipeline is arranged at one cone, the feed port and the discharge port are oppositely arranged in the rotation drying cabin, the heat supply unit is communicated with the pipeline port of the heat supply circulating pipeline, the through hole is connected with a vacuum pipeline, the vacuum pipeline extends into the rotation drying cabin along the through hole, and a cloth bag is arranged at the pipeline port. After the drying device disclosed by the invention is applied, since the two-cone rotation drying unit is adopted, oxidation of products by air is blocked, the loss of the products is reduced due to the sealed environment, the moisture content and the appearance color of the products are effectively controlled, the yield of the products is improved, the consumption is reduced, and the pollution to the atmosphere is reduced.
Description
technical field [0001] The invention relates to a drying device, in particular to a drying device for DHPPA, which mainly belongs to the technical field of chemical equipment. Background technique [0002] R-(+)-2-(4-hydroxyphenoxy)propionic acid ([chemical name] DHPPA) is finally crystallized in water, and the general product quality requires that the moisture content should not exceed 0.3%, so the product must be dried Only when the room is dry can it meet the quality standards. [0003] The drying equipment in the prior art is a tray-type drying oven. Although the moisture of the dried products can meet the requirements, the product loss is large, and some materials are blown into the air by a dehumidifying fan, causing air pollution; the appearance color is yellow (that is, some products deteriorate) , The appearance of the product is poor. Contents of the invention [0004] The object of the present invention is to propose a drying device for DHPPA. [0005] The pu...
