[0002] Solid sodium hypochlorite, a commonly used disinfectant, is widely used in water treatment, food processing, and environmental sanitation. In practical applications, it requires precise addition to the target system via an automated feeding device to ensure disinfection effectiveness and avoid material waste. Current solid sodium hypochlorite feeding devices suffer from two main problems: First, solid sodium hypochlorite is prone to absorbing moisture and clumping. Existing devices often lack effective mixing and dispersing structures, leading to clumped material clogging the feeding channel. Furthermore, the lack of a screening mechanism means that clumping or impurities added with the material can affect disinfection efficiency. Second, existing devices struggle to precisely control the feeding rate and rely heavily on manual feeding, resulting in cumbersome and inefficient operation, inability to guarantee stable feeding amounts, and difficulty in meeting the precise feeding requirements of different scenarios. Therefore, we propose an automated solid sodium hypochlorite feeding device. Utility Model Content

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] like Figure 1-3 As shown, this utility model is an automatic feeding device for solid sodium hypochlorite, including a cylinder 1. A conical feeding bin 11 is provided at the bottom of the cylinder 1. A stirring mechanism is provided at the upper part of the inner cavity of the cylinder 1. A frame 19 is provided below the stirring mechanism. A screen 2 is installed inside the frame 19. The lower end of the frame 19 is connected to a fixed block by a spring 21. A vibration motor 22 is installed on the frame 19. An inclined guide plate 23 is provided below the screen 2. A speed adjustment mechanism is provided below the guide plate 23. The speed adjustment mechanism includes a roller 24. Multiple flip plates 25 are provided on the side of the roller 24. One end of the roller 24 passes through the side wall of the feeding bin 11 and is connected to a feeding motor 26. A discharge pipe 27 is installed at the side opening of the feeding bin 11. A guiding mechanism is provided inside the discharge pipe 27. A feeding pipe 31 is provided at the bottom opening of the discharge pipe 27.

[0019] The cylinder 1 is the main supporting frame of the device, providing installation and working space for all internal functional mechanisms; the conical feeding hopper 11 uses gravity to guide the material to gather at the bottom, reducing the residual accumulation of material in the hopper; the stirring mechanism is used to pre-treat the material in the upper part of the cylinder; the frame 19 provides a stable mounting carrier for the screen 2; when the vibrating motor 22 works, it drives the frame 19 and the screen 2 to vibrate under the elastic support of the spring 21, thereby screening the material; the guide plate 23, through its inclined design, smoothly guides the screened material to the speed adjustment mechanism, preventing the material from falling directly and causing accumulation; in the speed adjustment mechanism, the feeding motor 26 drives the roller shaft 24 and the tilting plate 25 to rotate, and the material falling amount is adjusted by controlling the speed; the discharge pipe 27 receives the adjusted material, the internal guiding mechanism realizes automatic material conveying, and the discharge pipe 31 is the final output channel for material delivery. By coordinating the cylinder 1, feeding hopper 11, stirring mechanism, frame 19, screen 2, spring 21, vibrating motor 22, guide plate 23, speed adjustment mechanism (roller 24, tilting plate 25, feeding motor 26), discharge pipe 27, guiding mechanism and feeding pipe 31, the system achieves stirring and mixing, vibration screening, speed control and automatic feeding of solid sodium hypochlorite material. It solves the problems of easy material agglomeration leading to feeding blockage, lack of screening mechanism introducing impurities, uncontrollable feeding rate and need for manual feeding in the existing device, and improves feeding efficiency and material feeding accuracy.

[0020] In the above scheme, the bottom of the cylinder 1 is provided with multiple support columns 12. The multiple support columns 12 are evenly distributed at the bottom of the cylinder 1, which can provide stable support for the entire device, balance the forces generated by the device during stirring, vibration and other working processes, prevent the device from tilting or shaking violently, and ensure that each mechanism operates in a stable environment.

[0021] In the above scheme, the top of the cylinder 1 is detachably connected to a top cover 13, and a feed inlet 14 is provided in the middle of the top cover 13. At the same time, an openable sealing plate is provided inside the feed inlet 14. The top cover 13 adopts a detachable design, which makes it convenient for operators to open the cylinder 1 to inspect, clean or replace internal components such as the stirring mechanism and the screen 2. The feed inlet 14 is the channel for adding materials. The sealing plate is closed after the materials are added, which can prevent moisture in the outside air from entering the cylinder and causing the materials to absorb moisture and clump together. It can also prevent material dust from overflowing and polluting the environment, and at the same time prevent external impurities from falling into the cylinder and contaminating the materials.

[0022] In the above scheme, the stirring mechanism includes a rotating shaft 15, with multiple stirring paddles 16 disposed on the outer side of the rotating shaft 15. The end of the rotating shaft 15 extends through to the outside of the cylinder 1 and is connected to the stirring motor 17 for transmission. The stirring motor 17 provides the power source for the stirring action. When it operates, it drives the rotating shaft 15 to rotate synchronously. The multiple stirring paddles 16 on the outer side of the rotating shaft 15 rotate with the rotating shaft 15, which can perform all-round stirring of the solid sodium hypochlorite material in the upper part of the inner cavity of the cylinder 1, breaking up large clumps formed by moisture absorption in the material, keeping the material in a loose and uniform state, and providing qualified material for subsequent screening steps.

[0023] In the above scheme, an observation window 18 is provided on the side of the cylinder 1. The observation window 18 is made of a transparent and wear-resistant material (such as tempered glass). The operator can use the observation window 18 to view the remaining amount of material in the cylinder, the working status of the stirring mechanism, and the screening status of the screen 2 in real time, so as to keep abreast of the internal operating dynamics of the device and make it easy to replenish the material in time when it is insufficient, or to quickly detect and deal with problems such as abnormal stirring or screen blockage.

[0024] In the above scheme, the material guiding mechanism includes a discharge shaft 28, on which multiple feeding plates 29 are equally spaced. One end of the discharge shaft 28 is connected to a feeding motor 3. The feeding motor 3 provides power for the material guiding action. When it operates, it drives the discharge shaft 28 to rotate. The multiple feeding plates 29 on the discharge shaft 28 rotate synchronously with the discharge shaft 28, forming a spiral feeding structure. This structure can smoothly and evenly push and convey the material in the discharge pipe 27 along the pipe direction, avoiding material accumulation and blockage in the discharge pipe 27 and ensuring continuous material conveying to the lower material pipe 31.

[0025] In the above scheme, a solenoid valve is installed on the feeding pipe 31. The solenoid valve is connected to an external control system. The operator can control the opening or closing of the solenoid valve through the control system according to the actual feeding needs, thereby controlling the on / off of the feeding pipe 31, realizing precise control of the timing of feeding start and stop, and avoiding waste caused by the accidental discharge of materials when feeding is not required.

[0026] Working principle:

[0027] In this type of automatic solid sodium hypochlorite feeding device, the operator first opens the sealing plate inside the feed inlet 14 on the top cover 13 and feeds the solid sodium hypochlorite material into the cylinder 1 through the feed inlet 14. The material falls into the upper area of ​​the inner cavity of the cylinder 1 under the action of gravity. After the material is added to the preset amount, the sealing plate inside the feed inlet 14 is closed to prevent external moisture and impurities from entering the cylinder, and at the same time to prevent material dust from overflowing.

[0028] Material mixing stage: Start the stirring motor 17. The stirring motor 17 drives the rotating shaft 15 to rotate through the transmission structure. Multiple stirring paddles 16 on the outside of the rotating shaft 15 rotate synchronously with the rotating shaft 15. During the rotation, the stirring paddles 16 come into full contact with the solid sodium hypochlorite material in the cylinder, breaking up the clumps formed by moisture absorption in the material, so that the material as a whole remains loose and uniform, laying the foundation for subsequent screening steps.

[0029] Material screening stage: The loose material after stirring falls naturally onto the screen 2 inside the frame 19 below the stirring mechanism under the action of gravity; the vibration motor 22 is started, and the vibration force generated by the vibration motor 22 is transmitted to the frame 19. The frame 19 reciprocates under the elastic support of the bottom spring 21, which in turn drives the screen 2 to vibrate synchronously; the screen 2 intercepts the lumps and impurities in the material that have not been completely broken up on the surface of the screen 2 through vibration (which can be cleaned later by opening the top cover 13), and qualified materials that meet the particle size requirements fall through the mesh of the screen 2, thus completing the material screening and purification.

[0030] Material guiding stage: Qualified materials after being screened by screen 2 fall onto the inclined guide plate 23 below screen 2; with the help of the inclined angle of guide plate 23, the material slides smoothly along the surface of guide plate 23 under the action of gravity, slides out from the lower end of guide plate 23, and is accurately guided to the speed adjustment mechanism below guide plate 23, avoiding the material from falling directly onto the speed adjustment mechanism and causing accumulation.

[0031] Feeding rate adjustment stage: Start the feeding motor 26. The feeding motor 26 drives the roller shaft 24 to rotate at the corresponding speed according to the preset feeding rate requirement. Multiple flip plates 25 on the side of the roller shaft 24 rotate synchronously with the roller shaft 24. The material sliding down from the guide plate 23 enters the gap formed between the roller shaft 24 and the flip plates 25. The flip plates 25 gradually convey the material downward during the rotation process. By adjusting the speed of the feeding motor 26 (the faster the speed, the more material is conveyed per unit time, and vice versa), the feeding rate of the material can be precisely controlled. The adjusted material falls into the feeding hopper 11 and gathers at the opening of the discharge pipe 27 on the side of the feeding hopper 11.

[0032] Material discharge and conveying stage: After the material in the discharge hopper 11 enters the discharge pipe 27 through the opening, the feeding motor 3 is started. The feeding motor 3 drives the discharge shaft 28 to rotate, and the multiple feeding plates 29 on the discharge shaft 28 rotate synchronously with the discharge shaft 28. During the rotation, the feeding plates 29 push the material in the discharge pipe 27 to move along the pipe body direction, and smoothly and evenly convey the material to the bottom opening of the discharge pipe 27, so as to avoid the material from staying and accumulating in the discharge pipe 27 and causing blockage.

[0033] Final feeding stage: According to the feeding requirements of the target system, the external control system sends an opening signal to the solenoid valve on the feed pipe 31. The solenoid valve opens, and the material at the bottom opening of the discharge pipe 27 enters the feed pipe 31 and is transported to the target location (such as a water treatment reaction tank, disinfection equipment, etc.) through the feed pipe 31, completing the automatic feeding. When the feeding amount reaches the preset value or no further feeding is needed, the control system sends a closing signal, the solenoid valve closes, the feed pipe 31 stops discharging, and the feeding process ends. The operator can check the remaining amount of material in the cylinder through the observation window 18 on the side of the cylinder 1. If the material is insufficient, the above steps can be repeated for the next round of feeding.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
