Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and in particular to a sodium thiocyanate solid-liquid separation device. Background Technology

[0002] Sodium thiocyanate, as an important chemical raw material, is widely used in industries such as printing and dyeing, pharmaceuticals, and metallurgy. In the production process of sodium thiocyanate, it is often necessary to separate the solid-liquid mixture after crystallization to obtain a high-purity solid sodium thiocyanate product. Currently, the commonly used sodium thiocyanate solid-liquid separation equipment in the industry mostly adopts a process of filtration and drying in separate steps. That is, the solid particles are first separated by a filtration device, and then the separated solid is transferred to a drying device for dehydration.

[0003] Traditional equipment separates filtration and drying processes, requiring manual transfer or additional conveying devices to move the filtered solid material to the drying equipment. This not only increases operational steps and time costs but may also lead to production losses due to residues during material transfer. While some integrated equipment attempts to combine filtration and drying functions, the drying devices are mostly fixed structures, resulting in insufficient contact between hot air and solid material, which can easily lead to uneven drying in certain areas. This results in large fluctuations in the moisture content of the solid material, affecting product quality. To address these issues, this application proposes a sodium thiocyanate solid-liquid separation device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sodium thiocyanate solid-liquid separation device. This device integrates solid-liquid filtration and separation with solid drying functions within the same main frame, eliminating the need for additional material transfer devices or step-by-step operation processes. Through the synergistic design of hot air conveying and rotary stirring, hot air can be uniformly conveyed to the solid material area through the hollow structure. Simultaneously, the stirring component continuously agitates the material during rotation, ensuring full contact between the hot air and the material, effectively solving the problem of uneven local drying that is prone to occur in traditional fixed drying structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sodium thiocyanate solid-liquid separation device includes a processing box, a feed hopper that is fixedly connected to and extends through the top of the processing box, a separation frame that is fixedly connected to the inner wall of the processing box, a through-hole that extends through the bottom of the feed hopper and is fixedly connected to the top of the separation frame, a screening screen that is fixedly connected to the inner wall of the through-hole, a discharge port that extends through the right side of the separation frame, a motor that is fixedly connected to the side wall of the processing box, a transmission rod that is fixedly connected to the output end of the motor, the transmission rod that extends through the left end of the processing box and the separation frame and is rotatably connected to them, a spiral conveying blade that is fixedly connected to the outer wall of the transmission rod and is located inside the separation frame, a drying mechanism that is located below the separation frame, an interception frame that is fixedly connected to the inner wall of the processing box, and a water outlet hopper that is fixedly connected to the side wall of the processing box.

[0006] Preferably, the drying mechanism includes a hollow rod that passes through and is rotatably connected to the processing box. A plurality of hollow stirring rods are fixedly connected to the outer wall of the hollow rod. An electric hot air blower is fixedly connected to the side wall of the processing box. An air supply pipe is fixedly connected to the air outlet of the electric hot air blower. A rotary joint is sealed together with the hollow rod and the air supply pipe.

[0007] Preferably, a first pulley is fixedly connected to the outer wall of the transmission rod, and a second pulley is fixedly connected to the outer wall of the hollow rod. The outer walls of the first pulley and the second pulley are together fitted with a synchronous belt.

[0008] Preferably, the hollow stirring rods are distributed at equal intervals, and each hollow stirring rod has multiple vent holes through it.

[0009] Preferably, the bottom of the processing box is fixedly connected to a discharge hopper, the outer wall of the discharge hopper is fixedly connected to a first electromagnetic valve, and the outer wall of the water discharge hopper is fixedly connected to a second electromagnetic valve.

[0010] Preferably, the inner bottom of the water outlet hopper is flush with the bottom of the interception frame, the outer wall of the spiral conveying blade is attached to the inner wall of the separation frame, and the interception frame is located below the separation frame.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. This equipment integrates solid-liquid filtration and separation with solid drying functions into the same main frame, eliminating the need for additional material transfer devices or step-by-step operation processes. The process from the material entering the equipment to the completion of separation, drying and discharge is continuous, which not only reduces manual intervention steps and time costs, but also avoids production loss during material transfer, significantly improving overall processing efficiency.

[0012] 2. Through the synergistic design of hot air conveying and rotary stirring, hot air can be evenly conveyed to the solid material area through the hollow structure. At the same time, the stirring component continuously turns the material during rotation, so that the hot air and the material can fully contact each other, which effectively solves the problem of uneven local drying that is prone to occur in traditional fixed drying structures. Ultimately, it can ensure the stability of the moisture content of solid materials and reduce the risk of product quality fluctuations caused by poor drying effect.

[0013] In summary, this equipment integrates solid-liquid filtration and separation with solid drying functions into the same main frame, eliminating the need for additional material transfer devices or step-by-step operation processes. Through the synergistic design of hot air conveying and rotary stirring, hot air can be evenly conveyed to the solid material area through the hollow structure. At the same time, the stirring component continuously agitates the material during rotation, ensuring full contact between the hot air and the material, effectively solving the problem of uneven local drying that is prone to occur in traditional fixed drying structures.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-3A sodium thiocyanate solid-liquid separation device includes a processing box 1, which serves as the main mounting frame of the device. A feed hopper 2 is fixedly connected to the top of the processing box 1 to receive the solid-liquid mixture to be processed and guide the material into a separation frame 3. The separation frame 3 is fixedly connected to the inner wall of the processing box 1 as the place for the initial separation of the material, bearing and constraining the material to carry out solid-liquid separation operations inside. The bottom of the feed hopper 2 is fixedly connected to the top of the separation frame 3. An opening is provided through the bottom of the separation frame 3, and a screening screen 4 is fixedly connected to the inner wall of the opening to allow liquid to pass through and intercept solid particles, thereby realizing the initial separation of the solid-liquid mixture. A discharge port 6 is provided through the right side of the separation frame 3 to discharge the separated solid material from the separation frame 3.

[0018] A motor 7 is fixedly connected to the side wall of the processing box 1 to provide power output for the transmission system of the equipment. A transmission rod 8 is fixedly connected to the output end of the motor 7 to transmit the power of the motor 7 to the spiral conveyor blades 9 and drive them to rotate. The transmission rod 8 passes through the left end of the processing box 1 and the separation frame 3 and is rotatably connected to them. The outer wall of the transmission rod 8 is fixedly connected to the spiral conveyor blades 9 located inside the separation frame 3. By rotating, the solid material inside the separation frame 3 is pushed to move towards the discharge port 6. The outer wall of the spiral conveyor blades 9 is in contact with the inner wall of the separation frame 3, which can reduce material residue and clean the screening screen 4 to prevent it from clogging, ensuring that the solid material can be fully conveyed. A drying mechanism is provided below the separation frame 3 for drying the separated solid material.

[0019] The drying mechanism includes a hollow rod 11 that passes through and is rotatably connected to the processing box 1, serving as a channel for hot air conveying and driving the hollow stirring rods 12 to rotate. A first pulley is fixedly connected to the outer wall of the transmission rod 8, and a second pulley is fixedly connected to the outer wall of the hollow rod 11. The outer walls of the first and second pulleys are fitted with a synchronous belt 10. The rotation of the transmission rod 8 drives the hollow rod 11 to rotate synchronously. Multiple hollow stirring rods 12 are fixedly connected to the outer wall of the hollow rod 11, which guides the hot air inside the hollow rod 11 into the material and agitates the solid material during rotation. The multiple hollow stirring rods 12 are distributed at equal intervals. This ensures that the hot air and stirring action can be evenly applied to the material. Each hollow stirring rod 12 has multiple exhaust holes through which hot air is discharged and comes into contact with the solid material. An electric hot air blower 15 is fixedly connected to the side wall of the processing box 1 to generate hot air and provide a heat source for the drying process. The air outlet of the electric hot air blower 15 is fixedly connected to an air supply pipe 14 to deliver the hot air generated by the electric hot air blower 15 to the hollow rod 11. The hollow rod 11 and the air supply pipe 14 are jointly sealed with a rotary joint 13 to ensure that the hot air in the air supply pipe 14 can be stably passed in when the hollow rod 11 rotates, while ensuring the sealing of the connection.

[0020] The bottom of the processing box 1 is fixedly connected to a discharge hopper 5 for discharging the dried solid material from the equipment. A first solenoid valve is fixedly connected to the outer wall of the discharge hopper 5 to control the opening and closing of the discharge hopper 5 and adjust the timing of the solid material discharge. An interception frame 16 is fixedly connected to the inner wall of the processing box 1 to collect the liquid leaking from the screening screen 4 and guide it to the water outlet hopper 17. The interception frame 16 is located below the separation frame 3. The side wall of the processing box 1 is fixedly connected to the water outlet hopper 17 to discharge the liquid collected by the interception frame 16 from the equipment. A second solenoid valve is fixedly connected to the outer wall of the water outlet hopper 17 to control the opening and closing of the water outlet hopper 17 and adjust the timing of the liquid discharge. The inner bottom of the water outlet hopper 17 is flush with the bottom of the interception frame 16 to ensure that the liquid in the interception frame 16 can completely flow into the water outlet hopper 17 and avoid liquid residue.

[0021] In this invention, the operator starts the motor 7 and the electric hot air blower 15, injecting the material (the crystallized solid-liquid mixture) into the processing box 1 through the feed hopper 2. Under the action of gravity, the material first enters the separation frame 3. The screening screen 4 at the bottom of the separation frame 3 can filter the liquid in the material. The filtered liquid is collected on the interception frame 16 through the screening screen 4, and then discharged and collected through the water outlet hopper 17. At the same time, the output end of the motor 7 drives the transmission rod 8 and the spiral conveying blade 9 to rotate. When the spiral conveying blade 9 rotates, it can transport the solid in the material. The solid material is discharged through the discharge hopper. After being discharged from outlet 6, the material eventually falls to the bottom of processing box 1. The hot air blown out by electric hot air blower 15 passes through air supply pipe 14, hollow rod 11, and multiple hollow stirring rods 12 in sequence, and is discharged from exhaust port. After the hot air comes into contact with the solid material, it can evaporate the moisture on the surface of the solid material. In addition, when the transmission rod 8 rotates, it will drive the synchronous belt 10, hollow rod 11 and multiple hollow stirring rods 12 to rotate, thereby agitating the solid material and making the hot air fully contact the solid material to improve the drying effect. Finally, by opening the first electromagnetic valve, the dried solid material can be discharged and collected through discharge hopper 5.
