Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to pressure difference flash drying equipment. Background Art

[0002] Flash dryer is a new type of continuous drying equipment integrating drying, crushing and screening. Its working principle is that hot air enters the bottom of the dryer and forms a strong rotating wind field driven by the agitator. Paste materials enter the dryer from the spiral feeder. Under the strong action of the high-speed rotating stirring paddle, the materials are dispersed by impact, friction and shear stress. The block materials are quickly crushed, fully contacted with the hot air, heated and dried.

[0003] The existing dryer uses a stirring rod to rotate around the conical bottom surface. Under the action of gravity, the undried material will slide down and accumulate along the conical bottom surface. The material will be hit up by the rotation of the stirring rod. The stirring rod is subjected to a large impact force, which can easily cause damage to the stirring rod. It is also inconvenient to quickly disassemble and replace the stirring rod after it is damaged, and it is also inconvenient to clean the dust adhered to the inner wall of the dryer by the material hitting it. The dust is likely to adhere to the inner wall of the dryer after drying. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 5 In an embodiment of the utility model, a differential pressure flash drying device comprises a drying device body 1, a rotating shaft 2 is rotatably connected inside the drying device body 1, a support frame 201 is fixedly installed on the outer surface of the rotating shaft 2, a conical cover 5 is movably sleeved on the outer side of the support frame 201, a plurality of inverted conical material plates 501 are equidistantly fixedly installed on the outer surface of the conical cover 5, a spiral rod 506 is fixedly installed on the upper surface of the inverted conical material plate 501, a connecting rod 504 is fixedly installed on the upper surface of the conical cover 5, a square groove 202 is opened on the upper end surface of the rotating shaft 2, a receiving groove 204 is opened on the lower end surface of the square groove 202, a limiting assembly 3 is fixedly provided inside the receiving groove 204, the limiting assembly 3 comprises a fixed plate 301 and a rotating plate 302, a plurality of No. 2 slide grooves 303 are equidistantly opened on the upper surface of the fixed plate 301, a slider 305 is slidably connected inside the No. 2 slide groove 303, and a limiting plate 306 is fixedly installed on the upper surface of the slider 305.

[0025] Specifically, the inverted cone material plate 501 allows the material to fall on the surface of the cone cover 5 in layers, preventing the undried material from sliding down the cone surface and accumulating under the action of gravity. As the cone cover 5 rotates, the material is thrown out, allowing the air to drive the material to move upward for drying. The spiral rod 506 rotates with the rotation of the cone cover 5, sweeping the inner wall of the drying equipment body 1 to sweep away the dust adhered to the inner wall, thereby facilitating the cleaning of the dust adhered to the inner wall of the drying equipment body 1 caused by the material hitting the inner wall, so as to prevent the dust from adhering to the inner wall of the drying equipment body 1 after drying.

[0026] like Figure 3 As shown, in this embodiment, a motor 101 is fixedly installed on the lower surface of the drying equipment body 1 through a bracket, the rotating shaft 2 passes through the drying equipment body 1 and is rotatably connected to the drying equipment body 1, and the output end of the motor 101 is fixedly connected to the lower end surface of the rotating shaft 2.

[0027] In this embodiment, for the sake of clarity of description, the output end of the motor 101 is fixedly connected to the lower end surface of the rotating shaft 2 as an example. When the motor 101 runs, it drives the rotating shaft 2 to rotate, so that the conical cover 5 rotates, and the material above the inverted conical material plate 501 is thrown out, so that the conical cover 5 can rotate to throw the material outward, and the material is layered and falls on different positions of the conical cover 5. At the same time, by replacing the stirring component to stir the material, the impact on the stirring component is reduced, and the service life of the stirring component is increased.

[0028] like Figure 2-3 As shown, in this embodiment, a plurality of retaining rings 503 are fixedly installed on the inner surface of the conical cover 5, and the retaining rings 503 are movably engaged with the adjacent support frame 201, and a plurality of inclined plates 502 are fixedly installed at equal intervals between the inverted conical material plate 501 and the conical cover 5.

[0029] In specific implementation, the clamping ring 503 increases the firmness of the connection between the conical cover 5 and the rotating shaft 2, and at the same time, through the blocking of the inclined plate 502, the material is temporarily retained in the inverted conical material plate 501, thereby increasing the force of throwing the material out.

[0030] In order to solve the problem that the cone cover 5 is inconvenient to disassemble.

[0031] like Figure 2-4As shown, in this embodiment, the connecting rod 504 is movably engaged with the square groove 202, the upper end surface of the rotating shaft 2 is located on the outer surface of the square groove 202 and has a plurality of No. 1 slide grooves 203 equidistantly opened, the limiting plate 306 is slidably connected to the No. 1 slide groove 203, the outer surface of the connecting rod 504 is equidistantly opened with a plurality of limiting grooves 505, and the limiting plate 306 is movably connected to the limiting groove 505; the fixing plate 301 is fixedly installed with the inner surface of the storage groove 204, and the upper surface of the rotating plate 302 is equidistantly opened with a plurality of arc-shaped Slot 304, the slider 305 passes through the No. 2 slide slot 303 and is slidably connected with the arc slot 304, and a rotating rod 307 is fixedly installed on the lower surface of the rotating plate 302; the rotating rod 307 passes through the storage slot 204, and a gear 308 is fixedly installed on the lower end surface of the rotating rod 307, and the outer surface of the gear 308 is movably meshed with a tooth plate 309, and the tooth plate 309 passes through the rotating shaft 2; the outer surface of the rotating shaft 2 is located outside the tooth plate 309 and is movably sleeved with a limit frame 4, and a bolt 401 is screwed on the surface of one side of the limit frame 4.

[0032] During specific implementation, the tooth plate 309 is pushed to rotate the gear 308, and the rotating plate 302 is rotated through the transmission of the rotating rod 307. The arc groove 304 pushes the slider 305 to rotate, and the limit plate 306 is stuck inside the limit groove 505, and the connecting rod 504 is fixed to the inside of the square groove 202. Conversely, the tooth plate 309 is pulled to move the limit plate 306 out of the limit groove 505, so that the connecting rod 504 can be easily moved out from the inside of the square groove 202, thereby facilitating the rapid disassembly and replacement of the stirring assembly after it is damaged.
