Description
Technical Field
[0001] The utility model belongs to the field of chemical drying, and more specifically, it relates to a drying device for chemical industry. Background Art
[0002] Sodium stearyl fumarate is a widely used and important pharmaceutical and food auxiliary material. The synthesis of sodium stearyl fumarate is divided into three steps. The second step is isomerization, which converts the product from the cis configuration to the more stable trans configuration under the action of a catalyst. For the sodium stearyl fumarate isomerization process, after operations such as mixing, heating, heat preservation, and then cooling and crystallization of the auxiliary materials through a reaction vessel, the reaction solution is centrifugally separated and then dried to obtain sodium stearyl fumarate monoester.
[0003] Based on the above, the inventor of the present utility model found that the existing drying devices for chemical industry mainly have the following deficiencies, such as:
[0004] The materials placed in the drying box are the materials after solid-liquid centrifugal separation. Centrifugation removes most of the mother liquor but cannot completely dry it. The drying method of traditional drying devices is relatively fixed, and the water vapor evaporated during the drying process is easy to form lumps. For the rotating drum type drying device, the materials can only be placed at the bottom for rolling and stacking, which does not play a great role.
[0005] Therefore, a drying device for chemical industry needs to be proposed. Summary of the Utility Model
[0006] In order to solve the problems that the drying method of the above-mentioned traditional drying device is relatively fixed, the water vapor evaporated during the drying process is easy to form lumps, and for the rotating drum type drying device, the materials can only be placed at the bottom for rolling and stacking, which does not play a great role.
[0007] The purpose and effect of a drying device for chemical industry of the present utility model are achieved by the following specific technical means:
[0008] Its structure includes a moving box, a drying cylinder, a heat-insulating door, and a drying box. The drying cylinder is installed inside the moving box and can rotate. The moving box is placed inside the drying box and can move. The heat-insulating door is hinged to the drying box;
[0009] The drying cylinder includes a fixed cover, a limiting groove, an extension layer, a movable cylinder, and a movable cover. The limiting groove is embedded inside the fixed cover. The left and right sides of the extension layer are embedded inside the movable cylinder. The upper and lower ends of the movable cylinder are clamped between the fixed cover and the movable cover. The movable cylinder is clamped inside the limiting groove to play a role in restricting movement. The extension layer can play a role in stretching and connecting when the movable cylinder moves at the connection part.
[0010] As a further improvement of the present utility model, four movable cylinders are provided and evenly distributed in a circular shape. Four extension layers are provided and all are installed between two movable cylinders. The movable cylinders and the extension layers are connected in an arc structure. The fixed cover and the movable cover are driven to rotate as a whole by equipment control to drive the movable cylinders to rotate uniformly.
[0011] As a further improvement of the present utility model, the fixed cover includes a ventilation hole, a rotation port, and an outer cylinder. The ventilation hole and the outer cylinder are of an integrated structure. The rotation port is fixed on the outer surface of the fixed cover to drive the rotation. The outer cylinder is located outside the movable cylinder, and the outer cylinder limits the installation range of the internal parts.
[0012] As a further improvement of the present utility model, the movable cylinder includes a baffle, a limit block, a through hole, an inner groove, a main board, and a sliding groove. Two baffles are provided and fixed to the upper and lower ends of the main board. The limit blocks are installed in the middle of the upper and lower sides of the main board. The through hole and the main board are of an integrated structure. The inner groove is embedded in the main board. The limit block at the upper end of the main board is snapped into the limit groove, and the limit block at the lower end of the main board is snapped into the sliding groove for movement.
[0013] As a further improvement of the present utility model, two inner grooves are provided in a group and embedded in the left and right sides of the main board. The extension layer is fixed to the main board through the inner groove. The through hole connects the air inside and outside. The limit block assists the main board to be snapped into the sliding groove.
[0014] As a further improvement of the present utility model, the main board includes a clamping block, an extension body, and a convex block. The clamping block and the extension body are of an integrated structure. The clamping block drives the extension body to be snapped into the inner groove. The convex block is of a V-shaped structure, and two convex blocks are provided in a group and a total of four groups are provided.
[0015] As a further improvement of the present utility model, the protruding part of the convex block itself can drive the material to rotate to a higher point and fall to achieve the effect of active loosening. The baffles are in contact with the inner surfaces of the fixed cover and the movable cover in a static state. The extension body divides the main board into four sections to play a role in sectional movement.
[0016] Compared with the prior art, the present utility model has the following beneficial effects:
[0017] 1. When the drum is rotating at a uniform speed, when the movable drum turns to the top, it will slide down along the limit groove and the slide groove by its own gravity, and the extension layer connected to the inner groove will bend and deform. The drum rotates at a uniform speed. When the material adheres to the surface of the main board due to water evaporation during the drying process, it will be separated and fall due to the falling force of the main board. Its vents and ports play a role in sealing the limit groove and the slide groove to prevent the material from running in. The ports and vents connect the air on both sides of the inside and outside, and assist in evenly distributing the drying direction, so that the material can be dried better. The material can be dried after centrifugal separation. The evaporation of water vapor in the drying chamber affects the drying agglomeration and adhesion of the material, making it rotate and loosen, preventing it from adhering to the drying cylinder.
[0018] 2. During the overall rotation, the convex block can assist the material to continue to rotate to a higher point, and assist the material to rotate as far as possible to the upper end before falling down, playing a role of activity. During the sliding process of the main board, it is assisted and fixed by the card block and the extension body, which plays a sealing role on the connection between the two main boards to prevent the material from running out, and can smoothly rotate and dry the material. When the material is drying, it can assist in its rotation, so that the material can rotate to the highest point as far as possible before falling, so as to achieve the effect of loosening and turning over, and assist the drying effect.

The movable cylinder a4 is stuck inside the limiting groove a2 to play a role in restricting movement. The extension layer a3 can play a role in stretching and connecting when the movable cylinder a4 moves at the connection part. The movable cover a5 is connected to the drying cylinder 2.
[0030] Among them, four movable cylinders a4 are provided and are evenly distributed in a circular shape. Four extension layers a3 are provided and are all installed between two movable cylinders a4. The movable cylinders a4 and the extension layers a3 are all connected in an arc structure. The fixed cover a1 and the movable cover a5 drive the whole movable cylinder a4 to rotate uniformly through equipment control.
