Description

Technical Field

[0001] The utility model belongs to the technical field of fertilizer production, and in particular relates to a potassium sulfate finished product drying device. Background Art

[0002] Potassium sulfate is a water-soluble white crystalline salt. It is the most popular low-chlorine fertilizer in the world. The main resource of potassium sulfate is found in combination with other mineral sulfates (such as magnesium, sodium and calcium). About 95% of the total potassium sulfate product is used as fertilizer and 5% is used in other chemical industries. During the production process of potassium sulfate, a layer of material is placed on a linear conveying screen plate to vibrate the conveying plate. When the vibration acceleration is greater than the gravity acceleration, the material layer begins to expand and a vibrating fluidized state appears. At this time, the material placed on the conveying plate is strongly mixed and can easily move horizontally and tilted. Under this condition, the purpose of drying can be achieved by supplying heat to the material layer through convection, conduction and radiation.

[0003] The potassium sulfate finished product drying device of the prior art has certain requirements on the material particle size during operation, and the linear feed screen plate used therein will be directly blown away by the rising airflow when the material particle size is small, and this single-stage continuous screen plate will cause intense material backmixing and uneven material residence time, and it is possible that undried material will be discharged from the bed together with the product. Although a manhole for easy cleaning is generally provided on the outside of the device, it is always troublesome to enter the inside of the device through the manhole, and the internal space of the device is limited, which will result in cleaning dead corners, and the feed screen plate may be damaged when stepped on. Utility Model Content

[0004] The utility model aims to provide a potassium sulfate finished product drying device. The sieve plate one and the sieve plate two together constitute an S-shaped screening channel. The multi-level layered sieve plate can prevent the dried material from being mixed with the undried material, prolong the drying time of the material in the sieve plate channel, avoid the misdischarge of the undried material, and reduce the lift of the rising airflow on small particles to a certain extent. The sieve plate one and the sieve plate two can be slidably disassembled for easy cleaning, without the need for people to enter the interior of the drying device, thereby avoiding damage to the sieve plate due to trampling, and reducing sanitary dead corners.

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0025] According to the above structure, potassium sulfate material is injected from the top of the drying device 1, and the drying device 1 starts to vibrate. The material moves in an S shape from top to bottom in the screening channel formed between the sieve plate 1 2 and the sieve plate 202 and the U-shaped bend 203. This top-to-bottom movement process effectively prevents the material from mixing back, and the S-shaped sieve plate extends the channel length, so that the material is dried more fully, and an isolation layer is formed between the upper and lower sieve plates, which can block the flying small particles when the airflow rises.

The sieve plate 1 2 and the sieve plate 202 can be slid and disassembled for easy cleaning, and no one needs to enter the interior of the drying device 1, thereby avoiding damage to the sieve plate due to trampling, and reducing sanitary dead corners.

[0026] The working principle of the utility model is as follows: potassium sulfate material is injected from the top of the drying device 1, the drying device 1 starts to vibrate, and the material moves from top to bottom in an S-shaped sieve channel formed between the sieve plate 1 2 and the sieve plate 202 and the U-shaped bend 203. This top-to-bottom movement process effectively prevents the material from mixing back, and the S-shaped sieve plate extends the channel length, so that the material is dried more fully, and an isolation layer is formed between the upper and lower sieve plates, which can block the small particles that fly up when the airflow rises. In the shutdown state, the nut 102 is removed from the slotted bolt 105 by rotating it, and the nut 102 is removed from the outside of the drying device 1. The screw 107 is rotated by the wall, so that the screw 107 drives the screw tube 108 to move. While the screw tube 108 slides on the inner wall of the sleeve 106 through the sliding plate 110, it also drives the U-shaped bend 203, the sieve plate 202, and the sieve plate 2 to move through the connecting plate 109. The sieve plates 12 and 202 slide on the outer wall of the sliding strip 104 at the same time, and the embedded groove 205 leaves the embedded plate 101. The sieve plates 12 and 202 slide out from the interior of the drying device 1 through the slot 103. When the sieve plates 12 and 202 are embedded in the interior of the drying device 1, the edge sealing strip 201 seals the slot 103.
