Description

Technical Field

[0001] The utility model belongs to the technical field of drying equipment, and in particular relates to a device for preventing powder and granular materials from agglomerating. Background Art

[0002] For some powder and granular materials, they usually carry a large amount of moisture during the manufacturing process, so the finished product is very easy to clump, which means the quality of the product itself is not high. Although the moisture carried by the powder and granular can be removed by drying in some equipment, there is still a defect of low dehumidification efficiency in the actual production process, which makes the product still have a lot of lumps. Utility Model Content

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1 to Figure 3 As shown, a powder and granular material anti-caking equipment comprises a cylinder 1 and a cylinder 2 which are detachably connected in the vertical direction; the ends of the cylinder 1 and the cylinder 2 which are far away from each other are respectively provided with a gas outlet 3 and a gas inlet 4, the middle part of the cylinder 1 is provided with a material inlet 5, and the end of the cylinder 1 close to the cylinder 2 is provided with a material outlet 6, and the material inlet 5 and the material outlet 6 are both located on the cylinder wall of the cylinder 1; a drying component 7 is provided in the cylinder 2, and the air entering from the gas inlet 4 acts on the material in the radial direction of the cylinder 2 through the drying component 7 to make the material boil.

[0023] In this embodiment, the drying component 7 is provided with a plurality of hoods 8, and the hood 8 is provided with at least one air outlet 9 in its radial direction. A gas dispersion space 10 is provided between the drying component 7 and the gas inlet 4 so that the air speed blown out of each hood 8 is consistent. In different stages, the air velocity entering the cylinder 2 from the gas inlet 4 is different in this embodiment. In the initial stage, the powder and granular material enters the anti-caking device from the material inlet 5 and falls on the drying component 7, and then air with a velocity greater than 8m / s is introduced to fully boil the powder and granular material for a certain period of time, so that the moisture carried on the surface of the powder and granular material is fully removed. In this embodiment, the cylinder 1 has a drying space 11, which is located between the gas outlet 3 and the material inlet 5. After the moisture on the surface of the powder material is fully removed, the moisture rises to the drying space 11 with the air, so that the moisture can reduce the temperature of the powder material while vaporizing and evaporating. Since the drying space 11 has a certain relative height, the air velocity there will be reduced to no more than 3m / s, and the powder material originally covered by moisture will fall back onto the drying component 7. After a period of time, the velocity of the air entering the cylinder 2 is reduced to no more than 3m / s, and the powder material on the drying component 7 can flow out from the material outlet 6. In other words, when the wind speed is high, the air penetrates the powder material, so that the moisture between the powder materials can be separated, and the powder material carried by the moisture vaporizes and evaporates in the drying space 11, and the powder material falls back, and the vaporized moisture is discharged from the gas outlet 3 with the air, and then the powder material on the drying component 7 is ensured to be discharged from the material outlet 6 through vibration through the low wind speed.

[0024] In this embodiment, the drying space 11 has a gathering structure and is located at one end of the cylinder 1 where the gas outlet 3 is arranged. The gathering structure can better discharge air and vaporized moisture, thereby better maintaining the dryness of the drying device itself.

[0025] Furthermore, the drying component 7 is provided with multiple layers of wind hood 8 at intervals with its center as the center of the circle, and multiple wind hoods 8 are provided on each layer of wind hood 8 in a circular array. In this embodiment, there are multiple wind hoods 8, which are arranged in a certain rule so that the powder and granular materials on the drying component 7 can be fully blown. Furthermore, the distance between any two adjacent layers of wind hood 8 is equal, so as to provide a suitable resting position for the powder and granular materials and ensure that they are blown by air at any position. In this embodiment, the wind hood 8 is provided with multiple air outlets 9 along the circular array. It can be seen that in this embodiment, the air velocity passing through each air outlet 9 in each wind hood 8 at the same time is consistent, so that the dehydration effect of the powder and granular materials at any position on the drying component 7 is consistent, thereby well ensuring the quality consistency of the product.

[0026] Therefore, through this embodiment, the temperature of the powder and granular material dried in the previous stage can be reduced by more than 10°C, and in the application process of this embodiment, the amount of cooling and dehumidification air consumption is small, less than 200m 3 / ton; in addition, this embodiment does not require manual operation or control system; after drying by this embodiment, the heat exchange area of ​​subsequent cooling equipment can be reduced by 40%, effectively saving energy consumption.

[0027] In order to better use the present embodiment, the cylinder 1 and the cylinder 2 2 are detachably connected via a flange, so that it is convenient for the staff to disassemble and overhaul.

[0028] In the specific application of this embodiment, in the feed-grade monocalcium phosphate product production line, the product agglomeration problem is effectively solved. The temperature of the product treated by drum drying is 80-85°C after screening. After passing through the drying equipment provided by this embodiment, the temperature is reduced by more than 10°C, and the cooling and dehumidifying air volume consumed is less than 200m 3 / ton, reducing the heat exchange area of ​​the subsequent cooling equipment dust-free cooler by 40%.

[0029] In the production line of ammonium dihydrogen phosphate for batteries, the moisture content is effectively reduced from more than 0.5% to less than 0.08%, and the product temperature is reduced from 75°C to 55°C, effectively solving the problem of intercrystalline bridging in the product.

[0030] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
