Description

Technical Field

[0001] This utility model relates to a drying device for potassium sulfate production, belonging to the field of potassium sulfate technology. Background Technology

[0002] Potassium sulfate is an inorganic sulfate that is usually a colorless crystal with a bitter and salty taste. It is readily soluble in water, and its solubility increases with increasing temperature. It is insoluble in ethanol, acetone, and carbon disulfide. It can undergo a metathesis reaction with soluble barium salt solutions to form barium sulfate precipitate. Under different conditions, it can react with carbon to form different carbon oxides and potassium sulfite or potassium sulfide. When it reacts with acids, it can form potassium bisulfate.

[0003] Chinese Patent Publication No. (CN 222143563 U) discloses a potassium sulfate granular fertilizer drying device, including a drying chamber. A lid is hinged to the front of the drying chamber, and a lock is installed between the lid and the drying chamber. A sealing rubber strip is provided between the lid and the drying chamber. Guide rails are fixedly mounted side-by-side on the side of the lid facing the drying chamber. A mounting bracket is slidably mounted on the upper part of the guide rails, and a support is fixedly mounted side-by-side on the front of the mounting bracket. The design of the main pipe, valves, side branch pipes, distribution pipes, exhaust fan, and hot air fan in this invention facilitates the extraction of hot air from the drying chamber, preventing users from being burned by hot air when opening the drying chamber. The above-mentioned device simply piles potassium sulfate granules on top of the tray for drying. However, in actual use, because the potassium sulfate granules are piled up, the potassium sulfate granules near the inside cannot be directly baked by the hot air. This may occur after drying is completed, resulting in lower uniformity and effectiveness of drying the potassium sulfate granules, making it inconvenient for operators to use.

[0004] Therefore, a drying device for potassium sulfate production is proposed. Utility Model Content

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 like Figure 1-6 As shown, this utility model embodiment provides a drying device for potassium sulfate production, comprising: Drying assembly 1 includes a drying tank 101, a high-density filter cartridge 102 fixedly installed in the inner cavity of the drying tank 101, a feed inlet 103 fixedly installed on the top of the drying tank 101, a discharge valve 104 fixedly installed on the bottom of the drying tank 101, and a hot air pipe 105 connected to the front side of the drying tank 101, the other end of the hot air pipe 105 being connected to an external industrial hot air blower. The stirring assembly 2 includes a frame 201, which is fixedly mounted on the surface of the drying assembly 1. A drive motor 202 is fixedly mounted on the top of the frame 201. A lead screw 203 is fixedly connected to the output end of the drive motor 202. A screw block 204 is threaded onto the surface of the lead screw 203. An installation rod 205 is fixedly mounted on the front side of the screw block 204. An installation ring 206 is fixedly mounted on the front side of the installation rod 205. A tube body 207 is fixedly mounted on the inner side of the installation ring 206. A rotary motor 208 is fixedly mounted in the inner cavity of the tube body 207. A transmission rod 209 is fixedly connected to the output end of the rotary motor 208. A drive bevel gear 210 is fixedly mounted on the other end of the transmission rod 209. A fixing rod 211 is fixedly mounted on the bottom of the drive bevel gear 210. A drive motor 202 is fixedly installed in the tube body 207. A hollow tube 214 is movably connected to the bottom of the inner cavity of the tube body 207. A driven bevel gear 213 is fixedly installed at the top of the hollow tube 214. A fixing rod 211 passes through the inner surface of the driven bevel gear 213 and the inner cavity of the hollow tube 214 and extends to the outside of the tube body 207. A second stirring rack 215 is fixedly installed at the bottom of the hollow tube 214. A transmission bevel gear 216 is movably connected to the rear side of the inner cavity of the tube body 207. The surfaces of the transmission bevel gear 216 mesh with the surfaces of the driving bevel gear 210 and the hollow tube 214. The second stirring rack 215 and the first stirring rack 212 are both in the same vertical direction. The dimensions of the second stirring rack 215 and the first stirring rack 212 are the same. The rotation directions of the second stirring rack 215 and the first stirring rack 212 are opposite.

[0023] By setting up the stirring assembly 2, and through the output of the drive motor 202 and the rotary motor 208, the first stirring frame 212 and the second stirring frame 215 can rotate in opposite directions and move up and down to perform stirring. By stirring the potassium sulfate particles in the inner cavity of the high-density filter cartridge 102 in multiple directions and at different heights, the contact area between the potassium sulfate particles and the hot air entering the inner cavity of the drying tank 101 is increased, thereby improving the uniformity and effect of drying the potassium sulfate particles and making it convenient for operators to use.

[0024] Example 2 like Figure 1 , such as 3 and Figure 5As shown, in one embodiment, a guide groove 217 is provided on the top of the drying tank 101, and the tube body 207 passes through the inner cavity of the guide groove 217 and extends into the inner cavity of the high-density filter cartridge 102. Limiting grooves 218 are provided on both the left and right sides of the surface of the frame 201. The left and right sides of the screw block 204 are slidably connected to the inner cavities of the two limiting grooves 218. A temperature sensor 108 is fixedly installed on the left side of the top of the drying tank 101, and the detection end of the temperature sensor 108 extends into the inner cavity of the high-density filter cartridge 102. A humidity sensor 109 is fixedly installed on the right side of the top of the drying tank 101, and the detection end of the humidity sensor 109 extends into the inner cavity of the high-density filter cartridge 102. A base plate 106 is fixedly installed on the bottom of the drying tank 101, and anchor bolts 107 are threaded around the top of the base plate 106.

[0025] By setting the guide groove 217, the movement of the tube 207 can be limited to prevent it from deviating during movement, which would affect the stirring of potassium sulfate particles inside the high-density filter cartridge 102. By setting the limiting groove 218, the movement of the screw block 204 can be limited to prevent it from rotating synchronously with the lead screw 203. By setting the temperature sensor 108, the temperature inside the drying tank 101 and the high-density filter cartridge 102 can be detected, making it convenient for operators to understand the internal temperature. By setting the humidity sensor 109, the humidity inside the drying tank 101 and the high-density filter cartridge 102 can be detected, making it convenient for operators to understand the internal humidity. By setting the base plate 106 and the anchor bolts 107, the overall equipment can be stabilized to prevent accidental collisions that could cause the equipment to shake.

[0026] In operation, potassium sulfate granules are injected into the inner cavity of the high-density filter cartridge 102 through the feed inlet 103. Hot air from an external industrial hot air blower is then delivered to the inner cavity of the drying tank 101 via the hot air pipe 105, initiating the drying process. Simultaneously, the output of the rotary motor 208 drives the transmission rod 209, the driving bevel gear 210, the fixed rod 211, and the driven bevel gear 213 to rotate. When the driving bevel gear 210 rotates, it engages with the transmission bevel gear 216, causing the transmission bevel gear 216 to drive the driven bevel gear 213 to rotate. The driven bevel gear 213 drives the hollow tube 214 and the second stirring frame 215 to rotate, while the drive motor 202 outputs power, causing the lead screw 203 to drive the screw block 204 to move up and down reciprocally. The screw block 204 synchronously drives the mounting rod 205 and the mounting ring 206 to move. The mounting ring 206 drives the tube body 207 and its connected components to move up and down reciprocally with the first stirring frame 212 and the second stirring frame 215, so that the second stirring frame 215 and the first stirring frame 212 can stir potassium sulfate particles of different heights. After drying is completed, the potassium sulfate particles can be discharged through the discharge valve 104 to achieve the overall drying process.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
