Description

Technical Field

[0001] This utility model relates to the field of ammonium sulfate processing technology, and more specifically, to an automated discharge and shutdown device for an ammonium sulfate post-processing system. Background Technology

[0002] Ammonium sulfate is a widely used chemical fertilizer and raw material for the preparation of other chemicals. It is most commonly used as a nitrogen fertilizer, containing approximately 21% nitrogen and 24% sulfur, making it suitable for sulfur-deficient soils and crops. Ammonium sulfate can lower soil pH, making it suitable for alkaline soils, and is commonly used in the fertilization of crops such as rice, wheat, and corn. Simultaneously, ammonium sulfate can be used as a nitrogen source in fermentation media in the pharmaceutical and food industries.

[0003] After ammonium sulfate is produced in the reaction, the post-processing system includes crystallization, separation, and drying to obtain the finished ammonium sulfate product for packaging. Existing ammonium sulfate post-processing equipment, such as the ammonium sulfate mother liquor separation device disclosed in publication number CN209752236 U, connects the outlet of the crystallization tank to the inlet of a hydrocyclone via a conveying device, and the bottom outlet of the hydrocyclone is connected to the inlet of a centrifuge. Utilizing a hydrocyclone accelerates the concentration rate of ammonium sulfate crystals, avoids material blockage, improves separation efficiency, and saves equipment space.

[0004] However, in actual production, the following problems still exist in the downstream systems using hydrocyclones and centrifuges and urgently need to be solved:

[0005] When transporting ammonium sulfate from the centrifuge to the dryer, it is usually transported by a screw conveyor. However, since ammonium sulfate still contains some moisture after crystallization and separation but before drying, the screw conveyor will squeeze the ammonium sulfate during transport, causing blockages at the centrifuge outlet, screw conveyor, and dryer inlet. This requires manual cleaning after the machine is stopped, which is inefficient and requires specialized operators. Utility Model Content

[0006] This invention provides an automated discharge and shutdown device for ammonium sulfate post-systems to solve the problem of easy clogging of finished ammonium sulfate products in the prior art.

[0007] To address the aforementioned problems, this utility model provides an automated discharge and shutdown device for an ammonium sulfate post-system, comprising an inlet pipe, a hydrocyclone, a centrifuge, a screw conveyor, a dryer, and a silo. The ammonium sulfate solution enters the hydrocyclone through the inlet pipe. The hydrocyclone, centrifuge, screw conveyor, dryer, and silo are connected sequentially. The hydrocyclone has a conical structure. The ammonium sulfate solution undergoes a first-stage ammonium sulfate crystal separation within the hydrocyclone. The material containing ammonium sulfate crystals is then conveyed to the centrifuge for a second-stage ammonium sulfate crystal separation. The ammonium sulfate crystals separated by the centrifuge are conveyed to the dryer via the screw conveyor. After drying, the ammonium sulfate crystals are conveyed to the silo. The automated discharge and shutdown device for the ammonium sulfate post-system also includes a vibrating motor, which is at least installed on the side wall of the screw conveyor. The vibrating motor is used to shake off material adhering to the side wall of the screw conveyor.

[0008] Furthermore, there are at least four vibratory motors, which are respectively installed at the centrifuge outlet, the side wall of the front section of the screw conveyor in the conveying direction, the side wall of the rear section of the screw conveyor in the conveying direction, and the dryer inlet.

[0009] Furthermore, a camera is installed above the hydrocyclone to monitor its operating status.

[0010] Furthermore, radar level gauges and tuning fork level gauges are installed inside the silo to monitor the level of ammonium sulfate inside the silo.

[0011] Furthermore, the outlet of the hydrocyclone is provided with a first branch pipe and a second branch pipe. The first branch pipe is connected to the centrifuge, and the second branch pipe is connected to the diversion pipe. A first control valve is installed on the first branch pipe, and a second control valve is installed on the second branch pipe. The liquid outlet of the centrifuge is connected to the diversion pipe, and the outlet of the diversion pipe is connected to the feed tank.

[0012] Furthermore, the first control valve and the second control valve are electric valves. The automated discharge and shutdown device of the ammonium sulfate downstream system also includes an automatic control module. The radar level gauge, the tuning fork level gauge, the first control valve, and the second control valve are all electrically connected to the automatic control module. The automatic control module controls the opening and closing of the first control valve and the second control valve.

[0013] Furthermore, the liquid tank is equipped with a stirrer and is also connected to a pit, a self-priming tank, and a reaction tank.

[0014] Furthermore, the automated discharge and shutdown device for the ammonium sulfate post-system also includes an induced draft pipe. The upper part of the dryer is connected to the induced draft fan via the induced draft pipe to treat the gas evaporated inside the dryer.

[0015] Furthermore, the vibratory motor operates intermittently, with each operation lasting 3-10 seconds.

[0016] Furthermore, the inlet pipe is connected to the external absorption tower via a discharge pump and pipeline; the automated discharge and shutdown device of the ammonium sulfate post-system also includes a packaging machine, which transports the ammonium sulfate crystals from the silo to the packaging machine for packaging.

[0017] This invention provides an automated discharge and shutdown device for an ammonium sulfate post-system, comprising an inlet pipe, a hydrocyclone, a centrifuge, a screw conveyor, a dryer, and a silo. The ammonium sulfate solution enters the hydrocyclone through the inlet pipe. The hydrocyclone, centrifuge, screw conveyor, dryer, and silo are connected sequentially. The hydrocyclone has a conical structure. The ammonium sulfate solution undergoes a first separation of ammonium sulfate crystals within the hydrocyclone. The material containing ammonium sulfate crystals is then conveyed to the centrifuge for a second separation. The ammonium sulfate crystals separated by the centrifuge are conveyed to the dryer via the screw conveyor. After drying, the ammonium sulfate crystals are conveyed to the silo. The automated discharge and shutdown device also includes a vibrating motor, which is installed at least on the side wall of the screw conveyor. The vibrating motor is used to shake off material adhering to the side wall of the screw conveyor.

[0018] In this scheme, the conical structure of the hydrocyclone facilitates the initial separation of ammonium sulfate slurry. The hydrocyclone uses centrifugal force to separate the heavier ammonium sulfate crystals from the lighter liquid in the tangentially flowing ammonium sulfate slurry. Due to the conical structure of the hydrocyclone, the centrifugal force generated by the rotation of the ammonium sulfate slurry pushes the solid crystals against the outer wall. The solids are discharged along the conical outlet at the bottom of the hydrocyclone, while the mother liquor is discharged from the overflow port at the top, effectively separating the ammonium sulfate crystals from the solution. The centrifuge can further separate the ammonium sulfate crystals. Through high-speed rotation, a strong centrifugal force is generated. Due to the higher density of the solid particles, they are thrown against the outer wall of the centrifuge, while the liquid is discharged through the filter medium. This separates the liquid adhering to the ammonium sulfate crystals, improving purity and reducing the difficulty of subsequent processing. This two-stage separation ensures the purity of the ammonium sulfate crystals, separating most of the liquid, which reduces clogging at the centrifuge outlet, screw conveyor, and dryer inlet, improving work efficiency. Screw conveyors can continuously transport large quantities of materials. The enclosed screw casing prevents material leakage, reducing environmental pollution and ammonium sulfate loss. They also have a simple structure and small footprint. By incorporating a vibrating motor, material adhesion to the screw conveyor's sidewalls is reduced, helping to maintain cleanliness and efficient operation, minimizing material loss and further reducing blockages. The dryer ensures the dryness of the ammonium sulfate crystals entering the silo, facilitating long-term storage and transportation. The automated ammonium sulfate discharge and shutdown device in this solution reduces material spillage and blockages during production, improving work efficiency and reducing environmental pollution.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0040] like Figures 1 to 2 As shown, an embodiment of this utility model provides an automated discharge and shutdown device for an ammonium sulfate post-system, including an inlet pipe 1, a hydrocyclone 2, a centrifuge 6, a screw conveyor 8, a dryer 10, and a silo 11. The ammonium sulfate solution enters the hydrocyclone 2 through the inlet pipe 1. The hydrocyclone 2, centrifuge 6, screw conveyor 8, dryer 10, and silo 11 are connected in sequence. The hydrocyclone 2 has a conical structure. The ammonium sulfate solution undergoes a first separation of ammonium sulfate crystals in the hydrocyclone 2. The material containing ammonium sulfate crystals is conveyed to the centrifuge 6 for a second separation of ammonium sulfate crystals. The ammonium sulfate crystals separated by the centrifuge 6 are conveyed to the dryer 10 through the screw conveyor 8. After drying in the dryer 10, the ammonium sulfate crystals are conveyed to the silo 11. The automated discharge and shutdown device for the ammonium sulfate post-system also includes a vibrating motor 7, which is installed at least on the side wall of the screw conveyor 8. The vibrating motor 7 is used to shake off the material adhering to the side wall of the screw conveyor 8.

[0041] In this embodiment, the conical structure of the hydrocyclone 2 facilitates the initial separation of the ammonium sulfate slurry. The hydrocyclone 2 separates the heavier ammonium sulfate crystals from the lighter liquid by centrifugal force from the tangentially flowing ammonium sulfate slurry. Due to the conical structure of the hydrocyclone 2, the centrifugal force generated by the rotation of the ammonium sulfate slurry pushes the solid crystals against the outer wall. The solids are discharged along the conical outlet at the lower end of the hydrocyclone, while the mother liquor is discharged from the overflow port at the top, effectively separating the ammonium sulfate crystals from the solution. The centrifuge 6 can further separate the ammonium sulfate crystals. Through high-speed rotation, a strong centrifugal force is generated. Due to the higher density of the solid particles, they are thrown against the outer wall of the centrifuge 6, while the liquid is discharged through the filter medium. This separates the liquid adhering to the ammonium sulfate crystals from the ammonium sulfate crystals, improving purity and reducing the difficulty of subsequent processing. The purity of the ammonium sulfate crystals is ensured through two separations, separating most of the liquid. This reduces clogging at the outlet of the centrifuge 6, the screw conveyor 8, and the inlet of the dryer 10, improving work efficiency. The screw conveyor 8 can continuously transport large quantities of materials. Its enclosed screw casing prevents material leakage, reducing environmental pollution and ammonium sulfate loss. It also features a simple structure and small footprint. Furthermore, the installation of the vibrating motor 7 reduces material adhesion to the sidewalls of the screw conveyor 8, helping to maintain its cleanliness and efficient operation, minimizing material loss and further reducing blockages. The dryer 10 ensures the dryness of the ammonium sulfate crystals entering the silo 11, facilitating long-term storage and transportation. The automated ammonium sulfate discharge and shutdown device in this solution reduces blockages, improves work efficiency, and minimizes environmental pollution.

[0042] Furthermore, there are at least four vibrating motors 7, which are respectively installed at the outlet of the centrifuge 6, the side wall of the front section of the screw conveyor 8 in the conveying direction, the side wall of the rear section of the screw conveyor 8 in the conveying direction, and the inlet of the dryer 10.

[0043] In this embodiment, the vibration motor 7 can generate vibration. Vibration can prevent the adhesion and accumulation of ammonium sulfate crystals during the conveying process, reduce material blockage and accumulation at the outlet of centrifuge 6, the front and rear sections of screw conveyor 8, and the inlet of dryer 10. By reducing the blockage and accumulation of ammonium sulfate crystals, the continuity of production can be guaranteed, the downtime caused by clearing blockages can be reduced, and thus the efficiency can be improved.

[0044] like Figure 1 As shown, a camera 3 is installed above the hydrocyclone 2, and the camera 3 is used to monitor the working status of the hydrocyclone 2.

[0045] In this embodiment, camera 3 can monitor the operating status of the hydrocyclone 2 in real time, including the flow of ammonium sulfate slurry and whether there are any abnormalities inside the hydrocyclone 2. When the ammonium sulfate slurry overflows or fails to crystallize inside the hydrocyclone 2, the operator can promptly adjust the opening and closing of the first control valve 4 and the second control valve 5 to control the flow rate of the ammonium sulfate slurry and avoid overflow and waste. Using camera 3 to detect the working status of hydrocyclone 2 can promptly identify and handle problems, reduce downtime caused by malfunctions, and improve production efficiency. Furthermore, video recording and image analysis can quickly diagnose the cause of malfunctions in hydrocyclone 2, allowing for timely repair measures. Analyzing the data collected by camera 3 can also predict potential malfunctions and wear, enabling preventative maintenance and reducing unexpected downtime. Moreover, monitoring with camera 3 reduces the need for regular manual inspections of hydrocyclone 2, saving manpower.

[0046] The silo 11 is equipped with radar level gauges and tuning fork level gauges to monitor the level of ammonium sulfate inside the silo 11.

[0047] In this embodiment, by installing radar level gauges and tuning fork level gauges, the ammonium sulfate level in silo 11 can be continuously and accurately monitored, providing real-time level data. Once the preset height is reached, feedback will be immediately provided to prevent ammonium sulfate overflow and waste. The dual monitoring using radar and tuning fork level gauges is to prevent false alarms from a single level gauge under certain conditions, ensuring accurate and effective height monitoring to prevent ammonium sulfate from exceeding the capacity of silo 11, thus avoiding overflow and waste.

[0048] like Figure 1 As shown, the outlet of the hydrocyclone 2 is provided with a first branch pipe 15 and a second branch pipe 16. The first branch pipe 15 is connected to the centrifuge 6, and the second branch pipe 16 is connected to the diversion pipe 13. A first control valve 4 is provided on the first branch pipe 15, and a second control valve 5 is provided on the second branch pipe 16. The liquid outlet of the centrifuge 6 is connected to the diversion pipe 13, and the outlet of the diversion pipe 13 is connected to the feed tank 14.

[0049] In this embodiment, the first control valve 4 and the second control valve 5 can precisely control the flow rate from the hydrocyclone 2 outlet to the centrifuge 6 and the diversion pipe 13. When there is a large amount of ammonium sulfate in the hydrocyclone 2, it can flow from the overflow port at the top of the hydrocyclone 2 through the second branch pipe 16 to the diversion pipe 13, and finally to the material tank 14, reducing waste of ammonium sulfate during transportation and improving utilization. Furthermore, the ammonium sulfate at the hydrocyclone 2 outlet can be sent to the centrifuge 6 for further separation as needed, or undergo other treatments through the diversion pipe 13, improving overall separation efficiency. Moreover, the control valves can quickly cut off material flow in emergencies, reducing the risk of accidents.

[0050] Among them, the first control valve 4 and the second control valve 5 are electric valves. The automated discharge and shutdown device of the ammonium sulfate system also includes an automatic control module. The radar level gauge, the tuning fork level gauge, the first control valve 4, and the second control valve 5 are all electrically connected to the automatic control module. The automatic control module controls the opening and closing of the first control valve 4 and the second control valve 5.

[0051] In this embodiment, the first control valve 4 and the second control valve 5 are electric valves, which can precisely control the flow rate and reduce errors caused by human operation. Moreover, the solenoid valves are fast and can be quickly adjusted according to changes in the material level, thereby improving the accuracy of control. The automatic control module can automatically control the opening and closing of the valves based on the data provided by the radar level gauge and the tuning fork level gauge. When the information fed back by the radar level gauge and the tuning fork level gauge shows that the material level has reached the preset height, the automatic control module closes the first control valve 4 to prevent ammonium sulfate from entering the centrifuge 6, and opens the second control valve 5 to allow the ammonium sulfate in the hydrocyclone 2 to enter the diversion pipe 13 through the second branch pipe 16, and finally flow to the material tank 14, realizing a fully automated operation process.

[0052] like Figure 1 As shown, a stirrer is installed in the liquid tank 14, and the liquid tank 14 is also connected to a pit, a self-priming tank, and a reaction tank.

[0053] In this embodiment, a stirrer is installed inside the feed tank 14 to ensure that the ammonium sulfate in the tank maintains a certain degree of fluidity and prevents the precipitation of ammonium sulfate crystals. The feed tank 14 is connected to a pit, a self-priming tank, and a reaction vessel, allowing ammonium sulfate to be flexibly transferred between different equipment and also to other processes, improving production flexibility. The design of the feed tank 14 allows for rapid transfer of materials to the pit or self-priming tank for emergency handling in case of abnormal situations.

[0054] like Figure 2 As shown, the automated discharge and shutdown device of the ammonium sulfate post-system also includes an exhaust pipe 9. The upper part of the dryer 10 is connected to the exhaust fan through the exhaust pipe 9 to treat the gas evaporated inside the dryer 10.

[0055] In this embodiment, the induced draft fan can regulate the humidity inside the dryer through the induced draft duct 9, which helps maintain optimal drying conditions inside the dryer. By expelling the evaporated moisture, the drying speed of the material can be accelerated, improving drying efficiency. Furthermore, the induced draft duct 9 and the induced draft fan can prevent harmful substances or gases generated during the drying process from being directly emitted into the environment, reducing environmental pollution. The induced draft duct 9 can adjust the airflow and speed according to different types of materials to adapt to different drying requirements.

[0056] Furthermore, the vibration motor 7 operates intermittently, with each operation lasting 3-10 seconds.

[0057] In this embodiment, the multiple vibrating motors 7 are activated sequentially from back to front: first the vibrating motor on the dryer 10, then the vibrating motor on the rear side wall of the screw conveyor 8, followed by the vibrating motor 7 on the front side wall of the screw conveyor 8, and finally the vibrating motor 7 at the discharge port of the centrifuge 6. This intermittent operation mode reduces the energy consumption of the vibrating motors, providing vibration only when needed, thus saving energy. Furthermore, the "back-to-foreign" cleaning sequence is more efficient than other cleaning methods or simultaneous operation of multiple vibrating motors 7, and also reduces damage to the equipment. The working time of the vibrating motor 7 is 3-10 seconds, which reduces wear and extends its service life. It also helps the ammonium sulfate flow, preventing blockages, and avoids excessive vibration that could cause material dispersion or damage.

[0058] The inlet pipe 1 is connected to the external absorption tower via a discharge pump and pipeline; the automated discharge and shutdown device of the ammonium sulfate post-system also includes a packaging machine 12, which transports the ammonium sulfate crystals from the silo 11 to the packaging machine 12 for packaging.

[0059] In this embodiment, the packaging machine 12 includes a metering component, a packaging material conveying component, a filling component, a sealing component, a conveying component, and a control module. The metering module accurately measures and distributes ammonium sulfate according to a specific weight. The packaging material conveying component provides packaging materials such as bags and boxes. The filling component fills the metered ammonium sulfate into the packaging materials, with the filling method depending on the product type. The sealing component seals the filled packaging materials to ensure the airtightness of the packaging. The conveying component transports the packaged product to the next production stage or storage area. The control component controls the entire packaging process, including start-up, stop-up, and fault diagnosis. Automated conveying and packaging reduce the need for manual operation and improve packaging efficiency. Moreover, packaging by the packaging machine 12 ensures the consistency of the weight and quality of ammonium sulfate crystals in each package. Finally, connecting the liquid inlet pipe 1 to the absorption tower helps with waste gas treatment and reduces environmental pollution.

[0060] The automated discharge and shutdown device for ammonium sulfate post-processing provided in this application improves the separation efficiency and purity of ammonium sulfate crystals through dual separation using a hydrocyclone 2 and a centrifuge 6. The application of a vibrating motor 7 effectively avoids material adhesion problems during transportation, ensuring stable system operation. The introduction of an automatic control module automates the operation of the device, significantly reducing the need for manual intervention, improving production efficiency, and enhancing operational safety. The optimized overall structural design and component configuration of the device make the ammonium sulfate production process more environmentally friendly, reducing negative environmental impacts. This application's solution solves the problems of waste and blockage caused by overflowing ammonium sulfate product.
