Abstract
Description
Technical Field
[0001] This utility model relates to the field of sodium sulfate drying technology, and in particular to a sodium sulfate drying device. Background Technology
[0002] Sodium sulfate, also known as anhydrous sodium sulfate, is an important basic chemical raw material used in various fields such as detergents, papermaking, glass, and textile printing and dyeing. In industrial production, the drying of sodium sulfate is a key step in ensuring its product quality and performance. Dried sodium sulfate can not only effectively reduce the risk of clumping during transportation and storage, but also improve its dispersibility and stability in downstream applications. At the same time, it also puts forward higher requirements for the drying efficiency, energy consumption control and product quality stability of equipment. Traditional drying equipment is gradually becoming unable to meet the refined and efficient drying needs of modern chemical production.
[0003] In sodium sulfate drying equipment, heat conduction is used to form a thin film of sodium sulfate on the heated surface of a rotating drum. The drying process utilizes a heat transfer medium to transfer heat, avoiding direct contact between the material and hot air, reducing dust emissions, and improving drying safety and environmental friendliness to some extent. However, in actual operation, because the drum dryer primarily relies on the contact heat transfer between the sodium sulfate and the inner wall of the drum, the movement of the material within the drum is driven by gravity and the drum's rotation. This results in significant differences in the material's residence time and heated area within the drum. Material near the inner wall of the drum receives more heat, potentially leading to over-drying or even localized scorching. Conversely, material in the central area of the drum experiences less contact with the heated surface and insufficient heating, failing to achieve the desired drying effect. This uneven drying not only affects the consistency of sodium sulfate quality but also reduces the product qualification rate. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 4 An embodiment of this utility model is provided: a drying device for sodium sulfate, including a raw material silo 1, a drying mechanism 2 is provided on the right side of the raw material silo 1, the drying mechanism 2 is used to dry the pulverized raw material, a vibration mechanism 3 is provided on the right side of the drying mechanism 2, a placement rack 4 is provided on the right side of the vibration mechanism 3, a packaging mechanism 5 is provided inside the placement rack 4, the packaging mechanism 5 is used to package the finished product, and a dust removal mechanism 6 is provided on the front side of the drying mechanism 2.
[0033] The drying mechanism 2 includes a base plate 21. The left side of the base plate 21 is located on the right side of the raw material silo 1. Multiple dryers 22 are fixedly connected to the top of the base plate 21. The top of each of the multiple dryers 22 is fixedly connected to the same drying chamber 23. A discharge chamber 24 is fixedly connected to the right side of the drying chamber 23. A discharge assembly 25 is located at the bottom of the discharge chamber 24. A feeding assembly 26 is located on the left side of the drying chamber 23. A conveying assembly 27 is located on the left side of the feeding assembly 26.
[0034] Specifically, the drying mechanism 2 is based on the base plate 21 as the supporting component. Its left side is fixed to the right side of the raw material silo 1, and multiple dryers 22 are evenly distributed and fixed on the top. Each dryer 22 uses a combustion chamber to burn natural gas or biomass pellets to generate high-temperature flue gas. This high-temperature flue gas enters the drying chamber 23 and undergoes thorough mixing and heat exchange with the air, forming a uniform and stable hot airflow. The top of the dryer 22 is fixedly connected to the drying chamber 23 via a flange, forming a sealed drying space. A discharge hopper 24 is welded and fixed to the right side of the drying chamber 23. The bottom of the discharge hopper 24 is equipped with a discharge assembly 25 consisting of an electric push rod and a discharge valve. A feeding assembly 26 is installed on the left side of the drying chamber 23, which includes a feed hopper and a flow control valve. A conveying assembly 27 transports the sodium sulfate raw material from the raw material silo 1 to the feed hopper of the feeding assembly 26. The flow control valve of the feeding assembly 26 adjusts its opening according to drying requirements, controlling the speed at which the raw material enters the drying chamber 23. After the raw material enters the drying chamber 23, multiple dryers 22 start simultaneously. High-temperature hot air is supplied into the drying chamber 23, forming a circulating airflow that fully contacts the sodium sulfate raw material, removing moisture. A guide plate inside the drying chamber 23 guides the hot air to distribute evenly, ensuring uniform drying. The dried sodium sulfate is collected in the discharge chamber 24 on the right side of the drying chamber 23. When the raw material in the discharge chamber 24 reaches a preset height, the electric push rod of the discharge component 25 opens the discharge valve, allowing the raw material to be discharged through the discharge valve to the subsequent vibration mechanism 3. When the discharge valve is closed, its sealing ring tightly adheres to the inner wall of the discharge chamber 24 to prevent hot air leakage. A stable supply of raw material is achieved through continuous conveying by the conveying component 27 and flow control by the feeding component 26. The hot air circulation drying between the dryer 22 and the drying chamber 23 ensures thorough dehydration of the sodium sulfate. Automatic discharge control by the discharge component 25 maintains the continuity of the drying process, meeting the requirements of industrial production for drying efficiency and quality, while reducing manual intervention and improving automation.
[0035] Reference Figure 3 and Figure 5 The packaging mechanism 5 includes two finished product bins 51. The exterior of the two finished product bins 51 is fixedly connected to the top of the inner side of the placement rack 4. The bottom of the inner side of the placement rack 4 is fixedly connected to a placement plate 52. The rear end of the inner side of the placement rack 4 is fixedly connected to two packaging machines 53. The bottom of the inner side of the placement rack 4 is fixedly connected to a conveyor belt 54. A palletizer 55 is set on the right side of the conveyor belt 54. Pallets 56 are fixedly connected to the front and rear sides of the palletizer 55.
[0036] Specifically, the packaging mechanism 5 uses the placement frame 4 as a support frame. Two finished product bins 51 are symmetrically fixed to the top inner side of the placement frame 4, and a pneumatic gate is installed at the bottom opening. The placement plate 52 fixed to the bottom inner side of the placement frame 4 is used to temporarily receive the fallen finished products. Two packaging machines 53 are fixed to the rear inner side of the placement frame 4. The feed inlet 262 of the packaging machine 53 is aligned with the bottom opening of the finished product bin 51. It is equipped with an automatic weighing sensor and a sealing device. The conveyor belt 54 is installed at the bottom inner side of the placement frame 4. The palletizer 55 is located to the right of the conveyor belt 54. Its robotic arm can achieve three-dimensional movement and is equipped with a vacuum suction cup at the end. A pallet 56 is fixed to the front and rear sides of the palletizer 55. The surface of the pallet 56 is provided with positioning grooves. After the dried sodium sulfate is processed by the vibration mechanism 3, it is transported to the finished product bin 51 by the conveying pipe. The material level sensor in the finished product bin 51 monitors the material height. When the preset capacity is reached, the valve of the upstream conveying pipe is closed.
[0037] When packaging is required, the pneumatic gate opens, and the sodium sulfate falls into the feed inlet of the packaging machine 53. The weighing sensor of the packaging machine 53 monitors the weight of the material in real time. The feed inlet gate 262 closes, the sealing device starts, and the heat sealing process of the packaging bag is completed. The packaged finished sodium sulfate bag falls onto the placement plate 52 and is then conveyed to the right by the conveyor belt 54. When the packaging bag is conveyed to the end of the conveyor belt 54, the robotic arm of the palletizer 55 uses a vacuum suction cup to pick up the packaging bag and places it in the positioning groove of the tray 56 according to the preset program. The vision recognition system of the palletizer 55 monitors the process in real time. The system monitors the number and arrangement of pallet layers on pallet 56. Once one layer is completed, the robotic arm automatically adjusts its height to place the next layer until the set number of layers is reached. Through the temporary storage and quantitative feeding of finished product warehouse 51 and the precise weighing and sealing of packaging machine 53, standardized packaging of finished products is achieved. The stable transmission of conveyor belt 54 and the automated gripping and stacking of palletizer 55 improve the efficiency of the packaging process. In conjunction with the positioning design of pallet 56, it ensures that the palletizing is neat and stable, reduces manual intervention, lowers labor intensity, and meets the needs of industrial production for packaging efficiency and standardization.
[0038] Reference Figure 1 The discharge assembly 25 includes a discharge pipe 251, the top of which is connected to the bottom of the discharge bin 24, and the bottom of the discharge pipe 251 is connected to a discharge hopper 252. A conveyor belt 253 is fixedly connected to the bottom inner side of the discharge bin 24. The feeding assembly 26 includes a feeding bin 261, the right side of which is connected to the left side of the drying bin 23. A feed inlet 262 is fixedly connected to the top of the feeding bin 261, and a swaying device 263 is fixedly connected to the left side of the feeding bin 261. The conveying assembly 27 includes a fixed frame 271, the right side of which is located on the left side of the feeding bin 261. A burner 272 is fixedly connected to the left side inside the fixed frame 271, an auger 273 is fixedly connected to the inside of the fixed frame 271, and a conveyor belt 274 is fixedly connected to the right side inside the fixed frame 271.
[0039] Specifically, the discharge assembly 25 uses the discharge pipe 251 as the transmission channel. Its top is connected to the bottom flange of the discharge bin 24, and its bottom is connected to the discharge hopper 252. The conveyor belt 253 fixed to the bottom of the inner side of the discharge bin 24 is made of non-slip rubber. When the dried sodium sulfate in the drying bin 23 enters the discharge bin 24 and accumulates to the trigger height of the material level sensor, the conveyor belt 253 starts and transports the sodium sulfate to the discharge pipe 251. It is then discharged through the discharge hopper 252 to the subsequent vibration mechanism 3. The conveying direction of the conveyor belt 253 is consistent with the axial direction of the discharge pipe 251 to ensure smooth material transmission.
[0040] The right side of the feed bin 261 of the feeding assembly 26 is welded to the left side of the drying chamber 23. The top-fixed feed inlet 262 is connected to the discharge end of the conveying assembly 27. The oscillating device 263 installed on the left side consists of a motor and a crank-connecting rod mechanism. The motor speed is adjustable. The right side of the fixing frame 271 of the conveying assembly 27 is bolted to the left side of the feed bin 261. The burner 272 fixed on the left side inside is used to heat the air. The auger 273 inside the fixing frame 271 is driven by a motor and used to push the raw materials. The conveyor belt 274 on the right side is made of high-temperature resistant material and... The discharge end of the auger 273 is connected to transport the raw material to the inlet 262. When the equipment is running, the burner 272 of the conveying component 27 is started to preheat. At the same time, the auger 273 rotates to push the sodium sulfate raw material in the raw material bin 1 to the second conveyor belt 274. The second conveyor belt 274 transports the raw material to the inlet 262 and falls into the feeding bin 261. The motor of the oscillating device 263 drives the crank connecting rod mechanism to make the feeding bin 261 swing left and right, so that the raw material is evenly distributed in the drying bin 23 to avoid local accumulation. The dried sodium sulfate falls into the discharge bin 24.
[0041] When the material level sensor is triggered, conveyor belt 253 starts, transporting sodium sulfate to discharge pipe 251. Through the continuous conveying of conveyor belt 253, the stable discharge of dried sodium sulfate is achieved. The cooperation between auger 273 and conveyor belt 274 ensures a continuous supply of raw materials. The oscillating distribution of the material by the oscillating device 263 ensures that the raw materials are evenly distributed in the drying chamber 23, guaranteeing the uniformity of drying and improving the drying quality and production efficiency of sodium sulfate.
[0042] Reference Figure 2 , Figure 3 and Figure 4The vibration mechanism 3 includes a support frame 31. The left side of the support frame 31 is located at the bottom right side of the conveyor belt 253. A vibration motor 32 is fixedly connected to the top of the support frame 31. A screen 33 is fixedly connected to the top of the vibration motor 32. A discharge port 34 is opened on the right side of the screen 33. A conveyor belt 35 is fixedly connected to the bottom right side of the screen 33. The dust removal mechanism 6 includes a pulse dust collector 61. The rear side of the pulse dust collector 61 is located at the front side of the drying chamber 23. An induced draft fan 62 is fixedly connected to the right side of the pulse dust collector 61. A conveying pipe 7 is connected to the right side of the raw material silo 1. A suction machine 8 is connected to the left side of the conveying pipe 7.
[0043] Specifically, the vibration mechanism 3 is supported by a support frame 31. Its left side is fixed to the bottom right side of the conveyor belt 253, and the top is fixed with a vibration motor 32 by bolts. The output shaft of the vibration motor 32 is fixedly connected to the center of the screen 33. The screen 33 is made of stainless steel and has a discharge port 34 on its right side. The bottom right side of the screen is fixed with a conveyor belt 35. When the dried sodium sulfate is conveyed by the conveyor belt 253 to the left side of the screen 33, the vibration motor 32 starts and drives the screen 33 to vibrate synchronously. Under the action of vibration, the sodium sulfate moves to the right along the surface of the screen 33. Smaller particles fall through the screen 33 into the bottom conveyor belt 35 and are conveyed by the conveyor belt 35 to the finished product bin 51 of the packaging mechanism 5. Larger particles are discharged from the discharge port 34 and returned to the raw material bin 1 for re-crushing and drying to avoid blockage.
[0044] The rear of the pulse dust collector 61 of the dust removal mechanism 6 is connected to the front flange of the drying chamber 23, and the right side is connected to the induced draft fan 62 through a pipe. Filter bags are installed inside the pulse dust collector 61. When the equipment is running, the induced draft fan 62 starts, creating a negative pressure in the drying chamber 23, which drives the dust-laden hot airflow generated during the drying process into the pulse dust collector 61. When the airflow passes through the filter bags, the dust is trapped, and the purified gas is discharged by the induced draft fan 62. The control system of the pulse dust collector 61 blows the filter bags in reverse through the blowpipe, causing the attached dust to fall off. The raw materials in the raw material silo 1 are transported through the conveying pipe 7. The left side of the conveying pipe 7... The installed material extractor 8 provides the conveying power, drawing the raw materials into the fixed frame 271 of the conveying assembly 27 to ensure that it matches the processing capacity of the drying mechanism 2. The particle size classification of sodium sulfate is achieved through the vibration screening of the vibrating motor 32 and the screen 33, ensuring that the finished product has a uniform particle size. The dust-laden airflow in the production process is purified by the coordinated work of the pulse dust collector 61 and the induced draft fan 62, reducing dust emissions. The material conveying by the material extractor 8 and the conveying pipe 7 maintains the continuity of the production process, meets the requirements of industrial production for the accuracy of raw material classification and environmental protection standards, and improves the practicality and safety of the equipment.
[0045] Working principle: Production begins with the extraction and conveying of sodium sulfate raw material in raw material silo 1. After the feeder 8 starts, it generates suction through the conveying pipe 7 to draw sodium sulfate from raw material silo 1 into the fixed frame 271 of the conveying component 27. In the conveying component 27, the burner 272 preheats first, while the auger 273 rotates under the drive of the motor, pushing the raw material along the inside of the fixed frame 271 to the second conveyor belt 274. The second conveyor belt 274 is made of high temperature resistant material. After receiving the raw material, it conveys it to the feed port 262 of the feeding component 26, and then it falls into the feeding silo 261. At this time, the oscillating device 263 on the left side of the feeding silo 261, driven by the motor, makes the raw material evenly dispersed before entering the drying silo 23, avoiding local accumulation that affects the drying effect.
[0046] After the raw materials enter the drying chamber 23, the drying process officially starts. The bottom plate 21 of the drying mechanism 2 serves as the supporting foundation, and multiple dryers 22, evenly distributed and fixed on its top, operate synchronously. The dryers 22 use combustion chambers to burn natural gas or biomass pellets to generate high-temperature flue gas. After the high-temperature flue gas enters the drying chamber 23, it is fully mixed and heat-exchanged with the air to form a uniform and stable hot air. This hot air is continuously delivered into the drying chamber 23. The guide plates inside the drying chamber 23 guide the hot air to be evenly distributed. The hot air circulates within the chamber, making full contact with the sodium sulfate raw materials and removing moisture from the raw materials. The flow of the feed assembly 26... The quantity control valve adjusts the opening degree in real time according to the drying requirements to control the speed at which the raw materials enter the drying chamber 23, ensuring a stable drying process. After the raw materials are dried, they are collected in the discharge chamber 24 on the right side of the drying chamber 23. The material level sensor in the discharge chamber 24 monitors the material accumulation height in real time. When the preset height is reached, the electric push rod of the discharge assembly 25 pushes the discharge valve to open. The conveyor belt 253 at the bottom of the inner side of the discharge chamber 24 starts simultaneously, conveying the dried sodium sulfate along the discharge pipe 251 to the discharge hopper 252, and then discharging it to the subsequent vibration mechanism 3. When the discharge valve is closed, the sealing ring tightly fits the inner wall of the discharge chamber 24 to prevent hot air from leaking out.
[0047] The sodium sulfate discharged from the discharge component 25 enters the vibration mechanism 3 for screening. The support frame 31 of the vibration mechanism 3 is fixed to the bottom right side of the conveyor belt 253. After the vibration motor 32 is started, it drives the screen 33 to vibrate. The sodium sulfate moves from left to right on the screen 33. The qualified particles with smaller particle size fall through the screen 33 into the bottom of the conveyor belt 35 and are transported by the conveyor belt 35 to the finished product bin 51 of the packaging mechanism 5. The particles with larger particle size are discharged from the discharge port 34 on the right side of the screen 33 and returned to the raw material bin 1 for re-crushing and drying. The dust removal mechanism 6 operates synchronously to ensure a clean production environment. After the induced draft fan 62 is started, a negative pressure is formed in the drying bin 23, which introduces the dust-laden hot airflow generated during the drying process into the pulse dust collector 61. The purified gas is discharged through the induced draft fan 62, causing the attached dust to fall off and be collected in the dust collection box.
[0048] Qualified sodium sulfate, conveyed by conveyor belt 35, enters the finished product hopper 51 of the packaging mechanism 5 for temporary storage. A level sensor in the finished product hopper 51 monitors the material height. When the preset capacity is reached, the upstream conveying pipe valve closes. When packaging is required, the pneumatic gate at the bottom of the finished product hopper 51 opens, and the sodium sulfate falls into the feed inlet 262 of the packaging machine 53 below. The weighing sensor of the packaging machine 53 monitors the material weight in real time. After the set packaging weight is reached, the feed inlet 262 gate closes, the sealing device starts to complete the heat sealing process, and the sealed finished bag falls onto the placement plate 52. It is then conveyed to the right by conveyor belt 54, where the robotic arm of the palletizer 55 uses a vacuum suction cup to pick up the packaging bag. Its visual recognition system monitors the number of palletizing layers and their arrangement on the pallet 56 in real time. According to the preset program, it accurately places the packaging bags into the positioning grooves of the pallet 56. After one layer is completed, the robotic arm automatically adjusts its height to place the next layer until the set number of layers is reached, thus completing the palletizing process of the finished product. Through the coordination of the material extractor 8 and the conveying component 27, a stable supply of raw materials is achieved. The drying quality is ensured by the hot air circulation and precise material control of the drying mechanism 2. The raw material screening and environmental purification are completed by the vibration mechanism 3 and the dust removal mechanism 6. The packaging mechanism 5 realizes the automated packaging and palletizing of finished products, fully meeting the multiple requirements of industrial production for efficiency, quality and environmental protection.
