Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically a safe storage tank for polyaluminum chloride. Background Technology

[0002] Polyaluminum chloride (PAC) is a water treatment coagulant, also known as polyaluminum chloride, aluminum chloride, xanthate, etc. PAC has a high degree of charge neutralization and bridging effect on colloids and particulate matter in water, and can powerfully remove trace toxic substances and heavy metal ions. It is stable in nature and is usually in powder form, which is stored in large storage tanks.

[0003] An investigation revealed a utility model patent (publication number: CN215045548U) disclosing a safe storage tank for polyaluminum chloride. The tank includes a main body, with a filter plate fixedly connected to its inner wall. A motor is fixedly connected to the upper surface of the main body, and the motor's output shaft extends into the body and is fixedly connected to a rotating shaft. The end of the rotating shaft away from the motor extends below the filter plate. A fixing rod is fixedly connected to the side surface of the rotating shaft, and a push block is fixedly connected to the end of the fixing rod away from the rotating shaft. The push block has a cavity inside, and an extrusion groove is formed on the inner wall of the cavity. This utility model uses a motor to control the rotating shaft, which drives the push block to rotate, evenly spreading the polyaluminum chloride from the feed pipe onto the filter plate. Powdered polyaluminum chloride falls automatically, while flocculated polyaluminum chloride remains on the filter plate and is ground by a grinding wheel, preventing the flocculated polyaluminum chloride from clogging the feed pipe.

[0004] Although the aforementioned patent uses a grinding wheel to grind the material entering the tank, thus preventing flocculated material from clogging the discharge pipe, it can only grind and crush the material added to the tank. During the storage of materials in the tank, secondary flocculation and adhesion may occur inside the tank due to operations such as discharging, resulting in flocculated material still appearing during the discharging process and affecting the smoothness of the discharging.

[0005] Therefore, this utility model provides a safe storage tank for polyaluminum chloride to solve the above problems. Utility Model Content

[0028] 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. 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.

[0029] like Figure 1-5 As shown, this utility model provides a safe storage tank for polyaluminum chloride, including a storage component 1, which includes an outer tank 11, an inner tank 14 fixedly connected to the inner wall of the outer tank 11, a sealing cap 12 fixedly connected to the top of the outer tank 11, and a discharge pipe 15 fixedly connected to the bottom of the outer tank 11; a discharge component 2, which is circumferentially distributed between the outer tank 11 and the inner tank 14, and includes a feeding pipe 21, the inlet end of which is connected to the outlet end of the inner tank 14; and a transmission component 3, which is used for power transmission between the servo motor 13 and the discharge component 2. By storing materials inside the inner tank 14, and cooperating with the discharge component 2, the device first grinds and crushes the materials through the discharge component 2 during discharge, reducing the residue of flocculated materials. The double-layer sealing protection of the outer tank 11 and the inner tank 14 reduces the probability of moisture absorption of the materials inside the inner tank 14.

[0030] Furthermore, a servo motor 13 is fixedly connected to the upper surface of the sealing cover 12, and a first auger 16 is fixedly connected to the outer wall of the output shaft of the servo motor 13. The first auger 16 is rotatably disposed inside the inner tank 14. A feed pipe 17 is fixedly connected to the top of the inner tank 14, and the feed pipe 17 extends through to the top of the sealing cover 12. The bottom connecting plates of the outer tank 11 and the inner tank 14 are provided with a discharge hole, so that the grinding material of the feeding assembly 2 is collected through the discharge hole and discharged to the discharge pipe 15. The first auger 16 is driven by the servo motor 13 to rotate. The rotation of the first auger 16 can disperse the material inside the inner tank 14 and press the material down, so that the material enters the inside of the feeding pipe 21.

[0031] Furthermore, a driven shaft 23 is rotatably connected to the inside of the feeding pipe 21 via bearings, and a second auger 22 is fixedly connected to the outer wall of the driven shaft 23. A grinding wheel 24 is fixedly connected to the outer wall of the top end of the feeding pipe 21, and a grinding disc 25 is rotatably connected to the outer wall of the driven shaft 23. A gear ring 26 is fixedly connected to the upper surface of the grinding disc 25, and a first gear 27 meshes inside the gear ring 26. The first gear 27 is fixedly connected to the outer wall of the driven shaft 23. The feeding pipe 21 is fixedly connected to the bottom horizontal end of the outer tank 11 and the inner tank 14. The second auger 22 is used to lift materials inside the feeding pipe 21. The grinding wheel 24 and the grinding disc 25 are used for grinding powder. The outer wall of the driven shaft 23 is rotatably connected to the grinding disc 25 through ball bearings. The rotation of the driven shaft 23 drives the second auger 22 to rotate. At the same time, the rotation of the driven shaft 23 drives the grinding disc 25 to rotate through the meshing of the first gear 27 and the gear ring 26. This allows the material inside the feeding pipe 21 to rise and be guided when it comes into contact with the grinding disc 25. The material is then discharged through the grinding between the grinding wheel 24 and the grinding disc 25.

[0032] Furthermore, the transmission assembly 3 includes a drive shaft 31, which is fixedly connected to the top of the driven shaft 23. The outer wall of the drive shaft 31 is connected to the outer wall of the inner tank 14 through a bearing seat. A synchronous belt transmission mechanism 32 is connected to the top of the drive shaft 31. The other end of the synchronous belt transmission mechanism 32 is connected to a transmission shaft 33, which is rotatably connected to the top of the inner tank 14. A second gear 34 is fixedly connected to the outer wall of the transmission shaft 33, and a third gear 35 meshes with the outside of the second gear 34. The third gear 35 is fixedly connected to the outer wall of the output shaft of the servo motor 13. The servo motor 13 drives the third gear 35 to rotate, which in turn drives the second gear 34 to rotate. The synchronous belt transmission mechanism 32 drives the drive shaft 31 to rotate, thereby driving the feeding assembly 2 to perform grinding.

[0033] Working principle: When materials are needed, the valve of the feed pipe 15 is opened, and the servo motor 13 is started. The servo motor 13 further drives the first auger 16 to rotate, and at the same time, the driven shaft 23 is driven to rotate through the transmission component 3. While the first auger 16 is rotating, it presses the material down and conveys it into the feed pipe 21. At this time, the driven shaft 23 rotates and drives the second auger 22 to rotate, which drives the material to rise. When the material comes into contact with the grinding disc 25, it is guided and dispersed, and then ground with the grinding wheel 24. The ground material falls to the feed pipe 15 for discharge, ensuring that the discharged material is powdery and that the discharge is smooth, avoiding flocculated material that may cause blockage.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
