Description

Technical Field

[0001] This utility model relates to the field of potassium sulfate purification and refining technology, and more specifically, to a potassium sulfate purification system. Background Technology

[0002] Potassium sulfate purification equipment is a specialized system for removing impurities (such as organic matter, heavy metals, chlorides, etc.) during the potassium sulfate production process. Its core processes include high-temperature calcination to decompose organic matter, evaporation and crystallization purification, and solid-liquid separation.12 A typical equipment configuration includes a rotary kiln (800-1000℃ high-temperature decomposition), an MVR forced circulation evaporator (energy-saving concentration and crystallization), and a plate and frame filter press (solid-liquid separation), achieving precise temperature control and material proportioning through an automated control system.12 This equipment can improve the purity of potassium sulfate to industrial-grade standards (such as the requirements of the Guotou Luo Potassium Green Plant), while simultaneously achieving tail gas purification and waste heat recovery.

[0003] In the solid-liquid separation stage, the equipment typically injects the reaction solution and mixes it with potassium sulfate to achieve reaction purification, causing the potassium sulfate to dissolve and impurities to condense into solids. The solution is then purified by solid-liquid separation, discharged, and dried for further purification.

[0004] Current equipment struggles to control the feed rate when adding potassium sulfate containing impurities to the solution during the mixing stage. This can easily lead to excessive feed at once, slowing down the dissolution reaction, causing precipitation, and reducing reaction efficiency. Furthermore, the poor matching between the separately designed stirring mechanism and the feed rate results in ineffective mixing. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a potassium sulfate purification system to solve the problems that existing processing methods have difficulty controlling the feeding rate, which can easily lead to excessive one-time input, slow dissolution reaction rate, easy precipitation, and ultimately poor mixing effect.

[0006] To solve the above problems, the present invention adopts the following technical solution; A potassium sulfate purification system includes a mixing tank, a feeding tank, and a stirring mechanism. The feeding tank is fixedly installed on the mixing tank, and the bottom of the feeding tank has two discharge holes that communicate with the mixing tank. The stirring mechanism is installed inside the mixing tank and the feeding tank. The stirring mechanism includes a drive motor, a transmission rod, a discharge device, and a stirring section. The drive motor is fixedly installed inside the feeding box. The output end of the drive motor is fixedly connected to the transmission rod via a coupling. The transmission rod extends downwards sequentially into the mixing box and the feeding box. The discharge device is fixedly installed on the outside of the transmission rod and located inside the feeding box. The stirring section is fixedly installed on the outside of the transmission rod and located inside the mixing box. A filter element is fixedly installed inside the mixing chamber, and the bottom end of the transmission rod is rotatably connected to the filter element.

[0007] As a further description of the above technical solution: the discharge device includes a rotating disk and four through holes distributed in a ring on the rotating disk. The inner side of the rotating disk is fixedly connected to the outer side of the transmission rod, and the bottom of the rotating disk is rotatably connected to the inner side of the feeding box. The through holes intermittently cooperate with the discharge hole at the bottom as the rotating disk rotates.

[0008] As a further description of the above technical solution: a tapered sleeve is fixedly installed on the outer side of the transmission rod to guide the material into the through hole.

[0009] As a further description of the above technical solution: two T-shaped stirring rods are fixedly connected to the outer side of the transmission rod, and the vertical end of the T-shaped stirring rod is matched with the through hole at the bottom.

[0011] As a further description of the above technical solution: a discharge pipe 8 is provided on the left side of the bottom of the mixing box 1.

[0012] Compared with existing technologies, the advantages of this utility model are: (1) This scheme utilizes a stirring mechanism in conjunction with a discharge hole to achieve intermittent quantitative addition of potassium sulfate, controls the addition rate, and makes it mix more thoroughly and efficiently with the bottom reaction liquid, reducing precipitation and increasing the reaction rate.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] To address the problem that current equipment struggles to control the feed rate, easily leading to excessive initial input, slow dissolution reaction, precipitation, and reduced reaction efficiency, Example 1 is proposed: Please see Figure 1-4 In this utility model, the potassium sulfate purification system includes a mixing tank 1, a feeding tank 2, and a stirring mechanism 3. The feeding tank 2 is fixedly installed on the mixing tank 1. The bottom of the feeding tank 2 is provided with two discharge holes 4 that communicate with the mixing tank 1. The stirring mechanism 3 is installed inside the mixing tank 1 and the feeding tank 2.

[0018] The mixing mechanism 3 includes a drive motor 31, a transmission rod 32, a discharge device 33, and a mixing section 34. The drive motor 31 is fixedly installed inside the feeding box 2. The output end of the drive motor 31 is fixedly connected to the transmission rod 32 through a coupling. The transmission rod 32 extends downwards sequentially into the mixing box 1 and the feeding box 2. The discharge device 33 is fixedly installed on the outside of the transmission rod 32 and located inside the feeding box 2. The mixing section 34 is fixedly installed on the outside of the transmission rod 32 and located inside the mixing box 1.

[0019] A filter element 5 is fixedly installed inside the mixing box 1. The bottom end of the transmission rod 32 is rotatably connected to the filter element 5. A liquid inlet 6 is provided on the left side of the mixing box 1, an exhaust port 7 is provided on the right side of the mixing box 1, and a discharge pipe 8 is provided on the left side of the bottom of the mixing box 1.

[0020] In this embodiment, the reaction liquid is injected through the inlet hole 6 of the mixing tank 1, and then potassium sulfate containing impurities is placed inside the feeding tank 2. Then, the stirring mechanism 3 is started to rotate, which drives the discharge device 33 to rotate, so that the material falling hole intermittently connects with the bottom discharge hole 4, so that the potassium sulfate inside the feeding tank 2 falls intermittently and mixes with the reaction liquid at the bottom. This controls the falling rate of potassium sulfate, making the mixing with the reaction liquid more thorough. At the same time, the rotation of the transmission rod 32 also drives the bottom stirring section 34 to rotate, which stirs the mixture and makes the reaction thorough. Thus, the device has the advantages of controlling the falling rate of potassium sulfate and making the mixing with the reaction liquid more thorough and efficient.

[0021] Furthermore, considering the problem of poor mixing effect due to the low matching degree between the separately set stirring mechanism and the input rate, Example 2 is proposed: Please see Figure 2 and Figure 4 The discharge device 33 includes a rotating disk 331 and four through holes 332 distributed in a ring on the rotating disk 331. The inner side of the rotating disk 331 is fixedly connected to the outer side of the transmission rod 32. The bottom of the rotating disk 331 is rotatably connected to the inner side of the feeding box 2. The through holes 332 intermittently cooperate with the discharge hole 4 at the bottom as the rotating disk 331 rotates.

[0022] A tapered sleeve 321 is fixedly installed on the outside of the transmission rod 32 to guide the material to the through hole 332. Two T-shaped stirring rods 322 are fixedly connected to the outside of the transmission rod 32, and the vertical ends of the T-shaped stirring rods 322 are correspondingly engaged with the through hole 332 at the bottom.

[0023] In this embodiment, the rotating disk 331 rotates synchronously with the transmission rod 32, and the bottom stirring section 34 also rotates synchronously. When the top through hole 332 is intermittently connected with the discharge hole 4, potassium sulfate falls down, the bottom is stirred synchronously, and the potassium sulfate in the feeding box 2 is stirred by the T-shaped stirring rod 322 to avoid blockage and make the discharge smoother. Thus, the device has the advantages of synchronous discharge rate and bottom stirring, which improves the mixing efficiency.

[0024] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
