Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical product treatment, and particularly relates to a screening device for cyanuric chloride. Background Art
[0002] In the production process of cyanuric chloride, its raw material cyanogen chloride is prepared by reacting sodium cyanide with chlorine gas. The traditional cyanogen chloride chlorination reaction system includes a batcher, a reactor, an analysis kettle, a dehydration tank, a cooler, and a trap. A 30% aqueous sodium cyanide solution and water are prepared in the batcher to obtain a 15% aqueous sodium cyanide solution, which further reacts with chlorine gas in the reactor to obtain cyanogen chloride and an aqueous sodium chloride solution. The aqueous sodium chloride solution enters the analysis kettle from the bottom of the tower, and cyanogen chloride enters the dehydration tank from the top of the tower for dehydration. The aqueous phase enters the analysis kettle, and the gaseous cyanogen chloride enters the cooler to condense water. The aqueous phase enters the analysis kettle, and the gaseous cyanogen chloride enters the trap for further water removal. The aqueous phase enters the analysis kettle, and the gaseous cyanogen chloride enters the drying tower for the next synthesis. After cyanogen chloride enters the crystallizer, it enters the material storage bin. During the production process, crystallization and caking occur in the crystallizer, and the product forms plate caking after storage and transportation. Hard lumps that are difficult to break and are not screened by a sieve during the crystallization process in the crystallizer. Due to the relatively high humidity in the material, the product forms plate caking after storage and transportation, which is generally easy to break. Especially, the material in barrels without silicon is prone to caking. Due to the differences in the control of various process indicators during production, the particle size and fineness of the product cannot meet the requirements. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-5 , the present utility model provides a screening device for cyanuric chloride, including a main body frame 1. Above the interior of the main body frame 1, there is a hopper 2. Inside the main body frame 1 and below the hopper 2, there is a sieve cylinder 3. At the outer edge of the lower surface of the sieve cylinder 3, there is a connecting beam 4. At the four corners of the lower surface of the connecting beam 4, there are vibration springs 5 between the connecting beam 4 and the main body frame 1. At the upper end inside the sieve cylinder 3, there is a sieve plate 6. The lower wall of the hopper 2 is provided with through holes 7. On the lower surface of the hopper 2 and between the through holes 7, there is a leveling rod 8. At the lower end inside the sieve cylinder 3, there is an inclined plate 9. At a position corresponding to the inclined plate 9 on one side of the sieve cylinder 3, there is a discharge channel 10. On the other side of the sieve cylinder 3 and at the upper end of the sieve plate 6, there is a discharge port 11. At the middle position of the lower surface of the sieve cylinder 3, there is a vibration motor 12.
[0018] During use, the material to be screened is poured into the interior of the hopper 2. The hopper 2 is fixedly arranged at the upper end of the main body frame 1. Inside the main body frame 1 and below the hopper 2, the sieve cylinder 3 is flexibly connected through the vibration springs 5. At the lower end of the sieve cylinder 3, there is a connecting beam 4 to enhance the connection firmness between the vibration springs 5 and the connecting beam 4. The vibration motor 12 drives the sieve cylinder 3 to vibrate under the support of the vibration springs 5. The material inside the hopper 2 falls onto the sieve plate 6 inside the sieve cylinder 3 through the through holes 7. The material is screened by the sieve plate 6. The non-caked material falls onto the upper end of the inclined plate 9 inside the sieve cylinder 3. The inclined plate 9 guides the material and outputs it through the discharge channel 10. The caked material vibrates on the upper end of the sieve plate 6, and a leveling rod 8 is arranged at the lower end of the hopper 2. Due to the vibration of the sieve cylinder 3, the leveling rod 8 displaces relative to the sieve cylinder 3, thereby leveling and colliding with the caked material to break the caked material and make it fall to the lower end of the sieve plate 6. The tightly caked material is output externally through the discharge port 11.
[0019] A bottom beam 13 is provided at the lower end of the main body frame 1. The lower end of the vibration spring 5 is fixedly connected to the bottom beam 13. Below the main body frame 1 and at the lower end of the bottom beam 13, there is a base 14. The bottom beam 13 is arranged at the lower end of the main body frame 1 to support the lower end of the vibration spring 5. The base 14 is arranged at the lower end of the main body frame 1 to increase the overall height of the device and leave space for the installation of the vibration motor 12.
[0020] Inside the main body frame 1 and at a position corresponding to the lower end of the hopper 2, a fixing plate 15 is provided. The hopper 2 is fixedly connected to the main body frame 1 through the fixing plate 15. The hopper 2 is fixedly arranged at the upper end inside the main body frame 1 through the fixing plate 15, and the overall frame strength is enhanced.
[0021] At a position on the inner wall of the sieve cylinder 3 corresponding to the sieve plate 6, a limiting ring 16 is provided. The sieve plate 6 is fixedly connected to the limiting ring 16. The limiting ring 16 is arranged inside the sieve cylinder 3, and the sieve plate 6 is fixedly arranged inside the sieve cylinder 3 through the limiting ring 16, so that the sieve plate 6 can be disassembled.
[0022] Both the hopper 2 and the sieve cylinder 3 are of cylindrical structures, and the main body frame 1 is of a cuboid frame structure. The cuboid frame of the main body frame 1 leaves a moving space for the hopper 2 and the sieve cylinder 3 of the cylindrical structures.
