[0002] Sodium cyanate production refers to the inorganic chemical preparation process that uses cyanide as the core raw material, reacts it with an oxidant under specific temperature and pressure conditions, and then undergoes post-processing purification to finally obtain industrial-grade or reagent-grade sodium cyanate (NaOCN) products. In the sodium cyanate industrial preparation process, raw materials that meet the process purity requirements need to be fed into the standardized process steps of the reaction device through specific equipment.

[0003] During storage, raw materials are prone to moisture absorption and clumping. If they are not completely crushed and put into production, they will usually affect the subsequent preparation process of sodium cyanide and the quality of the finished product. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6As shown, a raw material feeding device for sodium cyanate production includes a housing 1, which is inclined to the horizontal direction. A crushing chamber 10 and a discharge chamber 11 are located inside the housing 1, below the crushing chamber 10. A drive mechanism is mounted on the housing 1, including a main shaft 202 rotatably connected to the inside of the crushing chamber 10. A crushing mechanism is located inside the housing 1, and the main shaft 202 drives the crushing mechanism to rotate. A transmission mechanism is located on the lower side of the housing 1, and the main shaft 202 drives the transmission mechanism to rotate. A discharge mechanism is located inside the discharge chamber 11. A planetary mechanism is located inside the crushing chamber 10, including a main gear 601 fixedly connected to the main shaft 202. A planetary gear 602 meshes with the top of the main gear 601 and is rotatably connected to the inner wall of the crushing chamber 10. At the top, a gear ring 603 meshes with the top of the planetary gear 602. The gear ring 603 is rotatably connected to the inner wall of the crushing chamber 10. Several spiral scrapers 604 are fixedly connected to the side of the gear ring 603 near the center of the housing 1. The rotation of the main shaft 202 also drives the main gear 601 to rotate. The rotation of the main gear 601 drives the planetary gear 602 and the gear ring 603 to rotate. The rotation of the gear ring 603 drives the spiral scrapers 604 to rotate, stirring the raw material at the bottom of the crushing chamber 10. The completely crushed raw material will fall down into the discharge chamber 11 through the filter screen 8. Larger particles that are not completely crushed will be lifted upward by the spiral scrapers 604 for further crushing to improve the crushing effect of the device. A splash-proof mechanism is provided at the top of the housing 1. The filter screen 8 is fixedly connected inside the housing 1, and the filter screen 8 connects the interior of the crushing chamber 10 and the discharge chamber 11. Several support legs 9 are fixedly connected to the housing 1.

[0018] The drive mechanism includes a motor 201, which is fixedly connected to the side of the housing 1 away from the filter screen 8, and a main shaft 202 is fixedly connected to the output end of the motor 201.

[0019] The crushing mechanism includes several crushing discs 301, several limiting shafts 302 are fixedly connected to the crushing discs 301, and several crushing teeth 303 are rotatably connected to the limiting shafts 302. When the motor 201 is started, the motor 201 drives the main shaft 202 and several crushing discs 301 to rotate. The rotation of the crushing discs 301 drives the limiting shafts 302 to rotate. During the rotation of the limiting shafts 302, the crushing teeth 303 will continuously rotate under the action of centrifugal force to crush the raw material. The crushed raw material will slide down to the bottom of the crushing chamber 10 under the action of gravity.

[0020] The transmission mechanism includes a drive wheel 401, which is fixedly connected to the side of the main shaft 202 away from the motor 201. A timing belt 402 is connected to the drive wheel 401, and a driven wheel 403 is connected to the bottom of the timing belt 402. When the main shaft 202 rotates, it drives the drive wheel 401 to rotate. The rotation of the drive wheel 401 drives the driven wheel 403 to rotate through the timing belt 402.

[0021] The discharge mechanism includes a secondary shaft 501, which is fixedly connected to the driven wheel 403. The secondary shaft 501 is rotatably connected to the inner surface of the discharge chamber 11. A spiral blade 502 is fixedly connected to the secondary shaft 501. A discharge pipe 503 is fixedly connected to the bottom of the housing 1 on the side near the motor 201. When the driven wheel 403 rotates, it will drive the secondary shaft 501 and the spiral blade 502 to rotate, lifting the raw material that falls into the discharge chamber 11 upwards, and finally discharging it from the discharge chamber 11 through the discharge pipe 503, thus completing the feeding of the raw material.

[0022] The splash-proof mechanism includes a hopper 701, which is fixedly connected to the top of the housing 1 near the motor 201. Two baffle plates 702 are hinged inside the hopper 701. Coil springs are built into both ends of the baffle plates 702. The raw materials required for preparing sodium cyanate are poured into the housing 1 through the hopper 701, and the external sodium cyanate preparation equipment is connected to one end of the discharge pipe 503. When the raw materials fall, the baffle plates 702 will be pressed down due to gravity, and the raw materials will fall into the crushing chamber 10. After the raw materials are added, the two baffle plates 702 will reset under the action of the coil springs to close the hopper 701, preventing the raw materials from splashing out of the hopper 701 during the crushing process, thus avoiding unnecessary impact.

[0023] Working principle: When using this device, the operator first pours the raw materials required for preparing sodium cyanide into the shell 1 through the hopper 701, and connects the external sodium cyanide preparation equipment to one end of the discharge pipe 503. As the raw materials fall, they will press the baffle plate 702 due to gravity, and the raw materials will fall into the crushing chamber 10. After the raw materials are added, the two baffle plates 702 will reset under the action of the coil spring to close the hopper 701, so as to prevent the raw materials from splashing out through the hopper 701 during the crushing process, thus causing unnecessary impact.

[0024] Then the motor 201 is started, which drives the main shaft 202 and several crushing discs 301 to rotate. The rotation of the crushing discs 301 drives the limit shaft 302 to rotate. During the rotation of the limit shaft 302, the crushing teeth 303 will continuously rotate under the action of centrifugal force to crush the raw material. After crushing, the raw material will slide down to the bottom of the crushing chamber 10 under the action of gravity.

[0025] The rotation of the main shaft 202 also drives the main gear 601 to rotate. The rotation of the main gear 601 drives the planetary gear 602 and the gear ring 603 to rotate. The rotation of the gear ring 603 drives the spiral scraper 604 to rotate, stirring the raw material at the bottom of the crushing chamber 10. The completely crushed raw material will fall down into the discharge chamber 11 through the filter screen 8. Larger particles that are not completely crushed will be lifted upward by the spiral scraper 604 for further crushing, thereby improving the crushing effect of the device.

[0026] When the main shaft 202 rotates, it drives the drive wheel 401 to rotate. The rotation of the drive wheel 401 drives the driven wheel 403 to rotate through the synchronous belt 402. The rotation of the driven wheel 403 drives the secondary shaft 501 and the spiral blade 502 to rotate, lifting the raw material that falls into the discharge chamber 11 upwards, and finally discharging it from the discharge chamber 11 through the discharge pipe 503, thus completing the feeding of the raw material.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
