Description

Technical Field

[0001] This application relates to the field of edible salt production equipment technology, and in particular to an edible salt iodine solution addition system. Background Technology

[0002] In the production of edible salt, iodization is a crucial step to ensure that the salt meets national standards and satisfies the human body's need for iodine. Currently, many salt mining companies, such as Kunming Salt Mine, generally use a method of adding iodine solution to the salt sand in solution form during the iodization process. After the iodine solution and salt sand are evenly mixed and the iodine content is tested and found to be qualified, the mixed material is then distributed to subsequent processes for packaging salt of various specifications.

[0003] In the aforementioned iodine solution addition process, existing technologies typically employ solenoid valves to directly control the flow of the iodine solution. However, because the valve core of the solenoid valve needs to be in direct contact with the iodine solution, and the entire addition equipment is located in a production environment with a high concentration of salt powder, the solenoid valve is prone to a series of malfunctions as the equipment's service life increases. On the one hand, the iodine solution is corrosive, causing corrosion damage to the solenoid valve core and related internal components; on the other hand, salt powder can easily enter the solenoid valve, causing the valve core to become stuck. These factors combined result in frequent malfunctions of the solenoid valve, such as leakage, improper opening and closing, and distorted operation.

[0004] More importantly, these malfunctions in solenoid valves often go undetected. This can lead to uncontrolled iodine solution addition, resulting in edible salt products with substandard iodine content, severely impacting product quality. Furthermore, the need for shutdown for repair or replacement of the faulty solenoid valve disrupts normal production processes and affects production continuity. In addition, frequent solenoid valve replacements significantly increase production costs, placing a substantial economic burden on companies.

[0005] Therefore, improving the operating environment of solenoid valves and reducing their failure rate has become an urgent problem to be solved in the current process of adding iodine solution to edible salt. Utility Model Content

[0006] To solve or partially solve the problems existing in related technologies, this application provides an edible salt iodine solution addition system, which can fundamentally eliminate the problem of solenoid valve corrosion caused by direct contact with iodine solution, and also avoid the failure of valve core jamming caused by salt powder directly entering the solenoid valve, thereby greatly reducing the failure rate of solenoid valve and extending the service life of solenoid valve.

[0007] This application provides a system for adding iodine solution to edible salt, comprising: Iodine solution storage tank 1; Delivery pipeline 2: One end is connected to the outlet of iodine solution storage tank 1, and the other end is connected to salt and sand mixing equipment 3; Ball valve 4: Installed on delivery pipeline 2; Control cylinder 5: Its output end is connected to the valve core of ball valve 4; Solenoid valve 6: electrically connected to the drive unit of regulating cylinder 5; Flow sensor 7: Installed on the delivery pipeline 2, located between ball valve 4 and salt-sand mixing equipment 3; Controller 8: Electrically connected to solenoid valve 6 and flow sensor 7 respectively.

[0008] Optionally, in some embodiments, the regulating cylinder 5 is equipped with a stroke sensor 9, which is electrically connected to the controller 8.

[0009] Optionally, in some embodiments, a filter 10 is provided at the connection between the delivery pipeline 2 and the iodine solution storage tank 1.

[0010] Optionally, in some embodiments, the solenoid valve 6 is provided with a protective shell, and the protective shell has heat dissipation holes.

[0011] The technical solution provided in this application may include the following beneficial effects: (1) Improve the operating environment of the solenoid valve and reduce the occurrence of failures: This application isolates the solenoid valve from the iodine solution by adding a cylinder and a ball valve. The solenoid valve no longer comes into direct contact with the iodine solution, but instead controls the cylinder's movement by sending commands to the cylinder, thereby driving the ball valve to open or close to add the iodine solution. This structural design fundamentally eliminates the problem of corrosion caused by direct contact with the iodine solution, and also avoids the problem of salt powder directly entering the solenoid valve and causing valve core jamming and other failures, which greatly reduces the failure rate of the solenoid valve and extends its service life.

[0012] (2) Ensure production continuity and improve product qualification rate: Since the failure rate of solenoid valves is significantly reduced, and even if ball valves or cylinders fail, their failure manifestations are more intuitive, making it easier for staff to discover and repair them in time. This effectively avoids the production of unqualified products due to failure of solenoid valves to be discovered in time, ensuring the continuity of the production process and improving the qualification rate of edible salt products.

[0013] (3) Reduce production costs: On the one hand, the service life of solenoid valves is extended, reducing the frequency of solenoid valve replacement and reducing equipment procurement costs; on the other hand, production continuity is improved, reducing production losses caused by downtime maintenance, and the reduction of defective products also reduces raw material waste, thus reducing the company's production costs in many ways.

[0014] (4) Precise control can be achieved: By setting up flow sensors, stroke sensors and controllers, the amount of iodine solution added can be precisely controlled, further ensuring the stability of iodine content in edible salt and improving product quality; the filter can ensure that system components are not affected by impurities, and the protective shell and corrosion-resistant conveying pipeline further extend the overall service life of the system and improve the reliability and stability of the system.

[0019] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0020] It should be understood that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] To address the aforementioned issues, this application provides an edible salt iodine solution addition system that fundamentally eliminates the corrosion problem of solenoid valves caused by direct contact with iodine solution. It also prevents salt powder from directly entering the solenoid valve and causing valve core jamming and other malfunctions, thereby significantly reducing the failure rate of the solenoid valve and extending its service life.

[0022] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0023] Example 1 See Figure 1 The edible salt iodine solution addition system includes: Iodine solution storage tank 1; Delivery pipeline 2: One end is connected to the outlet of iodine solution storage tank 1, and the other end is connected to salt and sand mixing equipment 3; Ball valve 4: Installed on delivery pipeline 2; Control cylinder 5: Its output end is connected to the valve core of ball valve 4; Solenoid valve 6: electrically connected to the drive unit of regulating cylinder 5; Flow sensor 7: Installed on the delivery pipeline 2, located between ball valve 4 and salt-sand mixing equipment 3; Controller 8: Electrically connected to solenoid valve 6 and flow sensor 7 respectively.

[0024] During operation, ball valve 4 is used to control the opening and closing of delivery pipeline 2, and regulating cylinder 5 is used to drive the valve core of ball valve 4 to rotate to realize the opening or closing of ball valve 4. Solenoid valve 6 sends an action command to regulating cylinder 5 to control the extension and retraction of regulating cylinder 5. Flow sensor 7 can detect the flow rate of iodine solution in delivery pipeline 2 in real time and transmit the flow signal to controller 8. Controller 8 issues adjustment command to solenoid valve 6 according to the preset flow range, and then adjusts the opening of ball valve 4 through regulating cylinder 5 to achieve precise control of the amount of iodine solution added, and further ensure the stability of iodine content in edible salt.

[0025] In actual operation, when iodine solution needs to be added to the salt and sand, the solenoid valve 6 receives a control signal and sends an action command to the regulating cylinder 5. Upon receiving the command, the regulating cylinder 5 extends or retracts, and its output terminal drives the valve core of the ball valve 4 to rotate, opening the ball valve 4. The iodine solution in the iodine solution storage tank 1 enters the salt and sand mixing equipment 3 through the delivery pipeline 2 and the open ball valve 4, completing the iodine solution addition. When no iodine solution needs to be added, the solenoid valve 6 sends a reverse command to the regulating cylinder 5, causing the regulating cylinder 5 to drive the valve core of the ball valve 4 to rotate in the opposite direction, closing the ball valve 4 and blocking the flow of iodine. Iodine solution delivery: Flow sensor 7 can detect the flow rate of iodine solution in delivery pipeline 2 in real time and convert the detected flow signal into an electrical signal and transmit it to controller 8. Controller 8 has a pre-stored flow range of iodine solution required for edible salt production. When the flow signal received by controller 8 exceeds or falls below the preset range, controller 8 will send an adjustment command to solenoid valve 6. Solenoid valve 6 controls the extension and retraction of regulating cylinder 5 according to the adjustment command, thereby adjusting the opening of ball valve 4, so that the flow rate of iodine solution is restored to the preset range, and the precise control of the amount of iodine solution added is achieved.

[0026] Example 2 See Figure 2 Based on Example 1, the regulating cylinder 5 is equipped with a stroke sensor 9, which is electrically connected to the controller 8.

[0027] The stroke sensor 9 can monitor the extension and retraction stroke of the control cylinder 5 in real time, thereby determining the opening degree of the ball valve 4 and feeding the signal back to the controller 8. The controller 8, combined with the signal from the flow sensor 7, can more accurately control the action of the control cylinder 5, ensuring that the opening and closing state of the ball valve 4 meets the production requirements and avoiding the problem of the ball valve 4 not opening and closing tightly due to the incomplete action of the control cylinder 5.

[0028] A filter 10 is installed at the connection between the delivery pipeline 2 and the iodine solution storage tank 1.

[0029] The filter 10 can filter the iodine solution entering the delivery pipeline 2 from the iodine solution storage tank 1, remove any impurities that may be present, prevent impurities from clogging the ball valve 4 or affecting the purity of the iodine solution, and ensure the stable operation of the system.

[0030] The solenoid valve 6 is provided with a protective shell, and the protective shell has heat dissipation holes.

[0031] The protective shell protects the solenoid valve 6, preventing salt powder from adhering directly to its surface or entering its interior, thus reducing damage. The heat dissipation holes help dissipate the heat generated during operation, preventing overheating and extending the valve's lifespan.

[0032] The delivery pipeline 2 is made of corrosion-resistant material. Since iodine solution is corrosive, the delivery pipeline 2, made of corrosion-resistant material (such as 304 stainless steel, polytetrafluoroethylene, etc.), can effectively resist the corrosion of iodine solution, extend the service life of the delivery pipeline 2, and reduce the occurrence of pipeline leaks and other failures.
