Description

Technical Field

[0001] This utility model relates to the field of sulfuric acid delinting technology for cotton seeds, and in particular to a fully automatic sulfuric acid delinting and acid preparation device for cotton seeds. Background Technology

[0002] In cotton seed processing, it is necessary to remove the residual lint from the cotton seeds to avoid affecting the germination rate after sowing. Currently, the main delinting method in the industry is dilute sulfuric acid delinting. Dilute sulfuric acid is mixed with cotton seeds to corrode and soften the lint on the cotton seeds. After dehydration, drying, and friction processes, the lint on the surface of the cotton seeds is removed.

[0003] Due to the variety of cottonseed varieties and the differences in pre-processing, the amount of down on the surface of cottonseeds varies after they enter the cotton seed processing plant. When mixing with dilute sulfuric acid, the required concentration of dilute sulfuric acid needs to be adjusted in real time according to the amount of down remaining on the surface of the cottonseeds.

[0004] Currently, the cotton seed processing industry commonly uses manual methods to prepare sulfuric acid. Concentrated sulfuric acid and water are mixed and stirred, then poured into a storage container for production use. When the concentration of dilute sulfuric acid needs to be adjusted, acid or water is added manually. This entire process requires manual intervention and frequent testing, sometimes relying on worker experience to determine the sulfuric acid concentration. On the one hand, manual handling of concentrated sulfuric acid poses significant safety hazards; on the other hand, the accuracy of dilute sulfuric acid concentration is low, affecting subsequent processing. Therefore, it is necessary to provide a fully automated sulfuric acid delinting and acid preparation device for cotton seeds to solve the above technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment Please refer to the following: Figure 1 ,in, Figure 1 A schematic diagram of the first embodiment of a fully automatic cotton seed sulfuric acid delinting and acid mixing device provided by this utility model.

[0018] A fully automated cotton seed sulfuric acid delinting and acid preparation device includes: a raw material storage unit, a mixing and dilution unit, a finished product standby unit, and a waste acid treatment unit; The raw material storage unit includes a concentrated sulfuric acid temporary storage tank 1, a water tank 2, and an activator tank 3. The mixing and dilution unit includes a dilution tank 4. The raw material storage unit is connected to the mixing and dilution unit through pipelines. The mixing and dilution unit is connected to the finished product waiting unit and the waste acid treatment unit through pipelines. The finished product waiting unit includes a No. 1 dilute acid tank 8 and a No. 2 dilute acid tank 9. The finished product waiting unit is connected to the pickling workshop 7 through an auger pipe. The waste acid treatment unit includes a waste acid tank 5 and a waste acid sedimentation tank 6. The waste acid treatment unit is connected to the pickling workshop 7 and the mixing and dilution unit through pipelines.

[0019] The surfactant tank 3 is used for manual addition of surfactants. The surfactant tank 3 adds the surfactant into the interior of the dilution tank 4 through pipes and a centrifugal dosing pump.

[0020] The water tank 2 adds water into the dilution tank 4 through pipes and a water supply pipe and an electromagnetic pump.

[0021] A stirring device is provided in the middle of the interior of the dilution tank 4, a sampling port is provided on one side of the bottom of the dilution tank 4, and a spray filter interface is provided on the top of one side of the dilution tank 4.

[0022] Concentrated sulfuric acid storage tank 1, water tank 2 and surfactant tank 1 are respectively transported to dilution tank 4 through pipelines and metering pumps.

[0023] The dilution water is usually demineralized water to avoid impurities affecting subsequent processes. Surfactant tank 3 stores surfactants to improve the properties of the diluted solution, such as wettability and stability.

[0024] The bottom of the surface of the dilution tank 4 is equipped with a sampling port for manual testing of parameters such as concentration and temperature of the mixture (e.g., acid concentration and density) to calibrate and correct the detection data of the detection instruments in the control system. It is also equipped with a stirrer and acid mist treatment to ensure uniform mixing of materials and heat dissipation (the dilution of concentrated sulfuric acid is highly exothermic, so the temperature rise needs to be controlled).

[0025] The dilution tank 4 is used to receive materials from the concentrated sulfuric acid storage tank, water tank, and surfactant tank. The system software controls the pipeline valves, thereby controlling the feeding sequence and flow rate.

[0026] • Waste acid sedimentation tank 6 removes solid impurities (such as cottonseed hulls, cotton lint, suspended solids, etc.) from waste acid through static sedimentation. After the supernatant meets the standards, it is discharged or reused. The sediment residue is treated as solid waste and is pumped to waste acid tank 5. Waste acid tank 5 collects waste acid generated during the production process (including unqualified products or solutions with excessive concentration deviations) and pumps it to dilution tank 4 to adjust the concentration for recycling.

[0027] The dilution process generates heat, which needs to be dissipated by stirring with a circulating pump. At the same time, a temperature sensor is installed on the surface of the dilution tank 4 to prevent overheating.

[0028] All pipes, valves, and tanks must be corrosion-resistant (e.g., lined with rubber or made of stainless steel), and the pump area must be equipped with a dike or leak-proof tray.

[0029] The working principle of the fully automatic cotton seed sulfuric acid delinting and acid mixing device provided by this utility model is as follows: During operation, concentrated sulfuric acid is first temporarily stored in concentrated sulfuric acid storage tank 1, while water tank 2 and surfactant tank 3 store dilution water and surfactant respectively. The flow rate is controlled by their respective metering pumps and the water and surfactant are delivered to dilution tank 4 in proportion. Dilution water and surfactant are first injected into dilution tank 4, and then concentrated sulfuric acid is injected.

[0030] The dilution tank 4 mixes and dilutes concentrated sulfuric acid, dilution water, and surfactant according to the process ratio. It receives materials from concentrated sulfuric acid storage tank 1, water tank 2, and surfactant tank 3. The system software controls the pipeline valves, thereby controlling the feeding sequence and flow rate.

[0031] The diluted finished acid solution is temporarily stored inside the No. 1 dilute acid tank 8 and the No. 2 dilute acid tank 9 to balance the production capacity of the upstream and downstream processes. It is then transported to the pickling workshop 7 through the auger pipeline to realize the cottonseed mixed acid process, which serves as the raw material for delinting.

[0032] After pickling in pickling workshop 7, the solution is transported to waste acid sedimentation tank 6 through pipelines. Solid impurities (such as cottonseed hulls, cotton lint, suspended solids, etc.) in the waste acid are removed by static sedimentation. After the supernatant meets the standards, it is discharged to waste acid tank 5 for recycling. The sediment residue is treated as solid waste.

[0033] Compared with related technologies, the fully automatic cotton seed sulfuric acid delinting and acid mixing device provided by this utility model has the following beneficial effects: This utility model provides a fully automatic sulfuric acid delinting and acid mixing device for cotton seeds. It coordinates five key stages: raw material storage, metering and conveying, mixing and dilution, finished product preparation, and waste acid treatment. The core of this system is the precise control of material ratios and the mixing process to achieve safe and efficient concentrated sulfuric acid dilution. Waste acid is also recycled and reused. The entire process is automated, with no human contact with the sulfuric acid. Overflow ditches, neutralization tanks, and safety dikes are installed around the system to ensure safe operation. This system presents a closed-loop process for concentrated sulfuric acid from storage, metering, dilution to finished product conveying and waste acid treatment. Its core features are precise proportioning, safe mixing, and environmentally friendly treatment. The system uses a PLC or DCS control system to link pumps, valves, and instruments, enabling automated operation and ensuring both production efficiency and safety / environmental protection. During actual operation, key monitoring focuses on dilution temperature, material flow rate, and waste acid indicators to prevent safety accidents and environmental risks.

[0034] Second Embodiment Please refer to the following: Figure 2 , Figure 3 and Figure 4 Based on the fully automatic cotton seed sulfuric acid delinting and acid mixing device provided in the first embodiment of this application, the second embodiment of this application proposes another fully automatic cotton seed sulfuric acid delinting and acid mixing device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0035] Specifically, the difference in the fully automatic cotton seed sulfuric acid delinting and acid mixing device provided in the second embodiment of this application is that the dilution tank 4 has a dilution chamber 10 inside, a feeding device 12 is fixedly installed on the top of the dilution chamber 10, and a guide device 11 is provided in the middle of the top of the feeding device 12.

[0036] The feeding device 12 includes a fixed ring block 121, feeding holes 122, guide blocks 123, and inclined grooves 124. The fixed ring block 121 is fixedly installed on one side inside the dilution chamber 10. A plurality of feeding holes 122 are equidistantly arranged around the outer surface of the top of the fixed ring block 121. A plurality of guide blocks 123 are equidistantly arranged around the outer surface of the bottom of the fixed ring block 121. The inclined grooves 124 are located in the middle of the top of the guide blocks 123.

[0037] The guiding device 11 includes a mounting ring block 111, a guiding block 112, and a guiding groove 113. The mounting ring block 111 is fixedly installed at the top center of the fixed ring block 121, the guiding block 112 is fixedly installed on the outer surface of the mounting ring block 111, and multiple guiding grooves 113 are equidistantly arranged around the outer surface of the guiding block 112.

[0038] The inner diameter of the mounting ring 111 and the fixing ring 121 facilitates the rotation of the stirring device.

[0039] The feed hole 122 and the inclined groove 124 are connected to facilitate the downward flow of concentrated sulfuric acid.

[0040] The guide block 112 is truncated cone-shaped with its surface tilted downwards to facilitate the flow of concentrated sulfuric acid, allowing the concentrated sulfuric acid to flow downwards towards the feed hole 22.

[0041] The working principle of the fully automatic cotton seed sulfuric acid delinting and acid mixing device provided by this utility model is as follows: During operation, the water and surfactant in water tank 2 and surfactant tank 3 are first injected into the dilution tank 4, and the concentrated sulfuric acid temporary storage tank 1 controls the entry of concentrated sulfuric acid into the dilution tank 4 through pipes and pumps.

[0042] Concentrated sulfuric acid flows along the guide block 112 into the surface of the fixed ring block 121, and falls down into the guide block 123 through the discharge hole 122. The concentrated sulfuric acid flows along the inclined groove 124 in the guide block 123 onto the inner wall surface of the dilution tank 4, so that the concentrated sulfuric acid flows down from the inner wall of the dilution tank 4 and mixes with the water.

[0043] Compared with related technologies, the fully automatic cotton seed sulfuric acid delinting and acid mixing device provided by this utility model has the following beneficial effects: This utility model provides a fully automatic sulfuric acid delinting and acid preparation device for cotton seeds. Through the cooperation of a guiding device 11 and a feeding device 12, concentrated sulfuric acid is guided into the dilution tank 4, flowing along the guiding block 112 into the surface of the fixed ring block 121, and then flowing through the feeding hole 122 from the inclined groove 124, steadily flowing down the inner wall surface of the dilution tank 4. This device has a simple structure and strong practicality. It slowly adds concentrated sulfuric acid to the water in the dilution tank 4, avoiding violent exothermic reactions that could cause liquid splashing, thus improving the safety of the concentrated sulfuric acid addition step. The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
