Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a drying equipment for preparing sodium chloride. Background Technology

[0002] Sodium chloride is an inorganic ionic compound, a colorless cubic crystal or fine crystalline powder, appearing as white crystals. Its main source is seawater, and it is the main component of table salt. It is easily soluble in water and glycerol, and slightly soluble in ethanol and liquid ammonia. Currently, sodium chloride is basically dried using a fluidized bed, thus requiring a drying device for sodium chloride preparation.

[0003] According to the patent application CN 221630276U, a disc drying device for sodium chloride is disclosed, which includes a shell, a feeding drying unit, a rotating shaft, and a drive unit. The feeding drying unit comprises several discs and several feeding groups. The discs are arranged at intervals from top to bottom, and each feeding group corresponds to a disc above it and is connected to the outer surface of the rotating shaft. The distance between two adjacent discs is at least 400mm. The uppermost feeding group inside the shell includes five rakes radially connected to the rotating shaft. This disc drying device for sodium chloride improves the feeding effect by setting five rakes at the top, preventing material from sticking to the discs and avoiding rake deformation and bending. The increased distance between the discs provides operating space for maintenance, increasing subsequent maintenance cycles, reducing the cost of vulnerable parts, increasing the overall stability of the device, and reducing operating costs.

[0004] Regarding the above description, the applicant believes the following problems exist: During operation, the first and second discs are arranged alternately, allowing material to flow continuously through the entire feed drying unit. The dried material falls from the last disc (the first disc) to the bottom of the outer casing and is then moved to the discharge port by the rake arm and its blades. However, this device can only perform simple drying of sodium chloride and cannot perform coarse or fine sieving. This may result in the dried sodium chloride requiring additional screening or processing steps to meet product quality requirements, which not only increases production costs but may also reduce production efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5This utility model provides an embodiment of a drying device for sodium chloride preparation, including a base plate 1; it also includes a screening box 21 and a feeding assembly. A support column 4 is fixedly connected to the bottom of the base plate 1, and a discharge hopper 5 is fixedly connected to the top of the base plate 1. The screening box 21 is fixedly connected to the top of the screening box 21, and the feeding assembly is located on the right side of the screening box 21. A crushing box 22 is fixedly connected to the top of the screening box 21, and a drying box 23 is fixedly connected to the top of the crushing box 22. A motor 24 is fixedly connected to the outside of the crushing box 22, and a gear crushing roller 25 is fixedly connected to the output end of the motor 24. A gear crushing roller 26 is located outside the gear crushing roller 25, and a rotating belt 27 is connected to the outside of the gear crushing roller 26. 27. A rotating disk 28 is driven to the end of the crushing roller 26 away from the gear. A rotating cam rod 29 is fixedly connected to the outside of the rotating disk 28. A rotating gear 210 is fixedly connected to the outside of the rotating cam rod 29. A rotating gear 211 meshes with the outside of the rotating gear 210. A rotating cam rod 214 is fixedly connected to the outside of the rotating gear 211. A screen plate 212 is slidably connected inside the screening box 21. A screen plate 213 is slidably connected to the end of the screening box 21 away from the screen plate 212. A motor 215 is fixedly connected to the bottom of the drying box 23. A rotating scraper 216 is fixedly connected to the output end of the motor 215. The rotating scraper 216 is driven by the motor 215 to move within the drying box 23. The internal rotation of unit 3 rapidly dries the sodium chloride inside the drying chamber 23. The dried sodium chloride then falls into the crushing chamber 22, where motor 24 drives gear crushing roller 25 and gear crushing roller 26 outside the gear crushing roller 25 to simultaneously crush the dried, agglomerated sodium chloride. The crushed sodium chloride then falls into the screening chamber 21. Gear crushing roller 26 drives rotating disc 28 outside the rotating belt 27, causing rotating disc 28 to drive rotating gear 210 outside the rotating cam rod 29. Rotating gear 210 drives rotating cam rod 214, which in turn rotates simultaneously with rotating cam rod 29. This causes rotating cam rod 29 and rotating cam rod 214 to continuously drive screen plates 212 and 213 within the screening chamber 21. The internal structure of the screening box 21 continuously vibrates, thereby screening the pulverized sodium chloride. Through holes are provided at corresponding positions of the motor 24 and the gear crushing rollers 25 and 26. Both gear crushing rollers 25 and 26 are rotatably connected inside the crushing box 22. The presence of the motor 24 facilitates the power supply for the rotation of the gear crushing rollers 25. Through holes are provided at corresponding positions of the screening box 21 and the rotating cam rods 29 and 214. The rotating cam rods 29 and 214 are rotatably connected inside the screening box 21. The presence of the rotating cam rods 29 and 214 facilitates the vibration of the sieve plates 212 and 213.Gear crushing roller 25 meshes with gear crushing roller 26. The presence of gear crushing roller 25 facilitates the crushing of sodium chloride in conjunction with gear crushing roller 26. The left and right sides of the screening box 21 have discharge ports opposite to sieve plates 212 and 213, which facilitate the screening of sodium chloride.

[0022] Please see Figure 5 In this embodiment, the feeding assembly includes a feeding pipe 31, which is fixedly connected to the outside of the drying chamber 23. A motor 32 is fixedly connected to the top of the feeding pipe 31, and a spiral blade 33 is fixedly connected to the output end of the motor 32. A discharge box 34 is fixedly connected to the outside of the feeding pipe 31. The presence of the drying chamber 23 facilitates the provision of an installation base for other components. Through holes are provided at corresponding positions of the feeding pipe 31 and the spiral blade 33. The spiral blade 33 is rotatably connected to the inside of the feeding pipe 31. The presence of the spiral blade 33 facilitates the movement of the raw materials inside the discharge box 34 into the interior of the drying chamber 23.

[0023] During operation, motor 32 drives the spiral blade 33 to rotate, causing the spiral blade 33 to carry the raw material from the feeding box 34 into the drying box 23. Motor 215 drives the rotating scraper 216 to rotate inside the drying box 23, rapidly drying the sodium chloride inside the drying box 23. The dried sodium chloride then falls into the crushing box 22. Motor 1 24 drives the gear crushing roller 26 outside the gear crushing roller 25 to rotate simultaneously, crushing the dried and agglomerated sodium chloride. The crushed sodium chloride falls into the screening box 21. The gear crushing roller 26 drives the rotating disk 28 outside the rotating belt 27 to rotate, causing the rotating disk 28 to drive the rotating gear 210 outside the rotating cam rod 29 to rotate. The rotating gear 210 drives the rotating cam rod 214 to rotate simultaneously with the rotating cam rod 29. The rotating cam rod 29 and the rotating cam rod 214 continuously drive the screen plate 212 and the screen plate 213 to vibrate continuously inside the screening box 21, thereby screening the crushed sodium chloride.

[0024] Through the above steps, motor 24 drives gear crushing roller 25 to rotate synchronously with external gear crushing roller 26 to crush dry, agglomerated sodium chloride. The crushed material then falls into screening box 21. Simultaneously, gear crushing roller 26 drives rotating disk 28 on rotating belt 27 to rotate. Rotating disk 28 further drives rotating cam rod 29 and its external rotating gear 210 to rotate. Rotating gear 210 interacts with rotating cam rod 214, causing both to rotate synchronously with rotating cam rod 29. This linkage mechanism causes rotating cam rod 29 and rotating cam rod 214 to continuously drive screen plates 212 and 213 to vibrate inside screening box 21, which is beneficial for screening the crushed sodium chloride. This allows for direct subsequent processing or screening to meet product quality requirements, reducing production costs and improving production efficiency.
