[0024] To further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail with reference to the accompanying drawings as follows.

[0025] As Figures 1 to 4 shown, a novel leak - proof fluidizer provided by an embodiment of the utility model includes a pipe joint 1 welded to the side wall of a bin pump. A claw platform 11 is provided at the upper end of the pipe joint 1, and an annular groove 12 is provided at the lower end of the pipe joint 1. A pipe clamp 13 is arranged in the annular groove 12. A fluidization pipe 14 is arranged on the pipe joint 1. A sealing assembly 15 is arranged between the pipe joint 1 and the fluidization pipe 14. A nut 26 is connected to the fluidization pipe 14 by a thread, and the nut 26 is used to fix the fluidization pipe 14. A silica gel air disc 4 is sleeved outside the fluidization pipe 14, and the silica gel air disc 4 is used to assist air flow.

[0026] Further, as one of the core components of the fluidizer, the pipe joint 1 is welded to the side wall of the bin pump where the fluidizer needs to be installed. This welding method not only enhances the structural strength but also reduces the leakage risk caused by loose connections. Then, the fluidizer is passed through the pipe joint 1, and then the fluidizer is fixed to the pipe joint 1 by tightening the nut 26. And then the fluidization inlet pipe is connected to the pipe joint 1 through the pipe clamp 13. The welded pipe joint 1 and the pipe clamp 13 at the end of the pipe joint 1 can strengthen the stability of the connection with the bin pump, thereby preventing leakage and loosening problems.

[0027] Further, a claw platform 11 is provided at the upper end of the pipe joint 1. The outer diameter of the claw platform 11 is larger than the aperture on the bin pump. After being fixed by welding, the claw platform 11 can penetrate into the bin pump wall to form a more firm mechanical lock, effectively preventing the joint from loosening due to vibration or pressure changes.

[0028] Further, the function of the pipe clamp 13 is to further reinforce the connection between the fluidization connection pipe 2 and the pipe joint 1, preventing it from falling off due to external forces during use. At the same time, the pipe clamp 13 can enhance the overall sealing performance.

[0029] Specifically, the fluidization pipe 14 includes a connection pipe 2. The connection pipe 2 is a straight pipe with a smooth outer wall. A porous pipe 21 is provided at the upper end of the connection pipe 2, a stud 23 is provided at the upper end of the porous pipe 21, and a threaded pipe 22 is provided at the lower end of the connection pipe 2. The interiors of the connection pipe 2, the porous pipe 21, and the threaded pipe 22 are all hollow and ventilated.

[0030] Specifically, the connection pipe 2 is slidably connected to the pipe joint 1.

[0031] Furthermore, a plurality of holes are provided on the porous tube 21. These holes allow air to pass through and disperse into fine airflows, thereby forming a uniform airflow distribution in the material. The design of the porous tube 21 effectively improves the fluidization effect, enabling air to penetrate more uniformly into the material, promoting the dispersion and flow of the material. In addition, the fine airflows also help to break the adhesion force between the material particles, further improving the flow efficiency.

[0032] Furthermore, the outer wall of the threaded tube 22 is machined with threads for threaded connection with the nut 26. According to the trapezoid of the threaded connection, this connection method is both firm and reliable, and is convenient for disassembly and maintenance.

[0033] Furthermore, the design of the threaded tube 22 makes the connection between the fluidization tube 14 and the pipe joint 1 tighter and more stable, effectively preventing leakage problems caused by loose connections. At the same time, the threaded connection also facilitates users to disassemble and replace components as needed, improving the maintainability of the equipment.

[0034] Specifically, the sealing assembly 15 includes a snap ring 3 and a rubber ring 31. The number of snap rings 3 is two. The two snap rings 3 are spliced and fastened. At both ends of one snap ring 3, there are provided snap blocks 32. At both ends of the other snap ring 3, there are provided limiting grooves 33. The limiting grooves 33 are correspondingly arranged with the snap blocks 32. The snap blocks 32 are inserted into the limiting grooves 33. The snap ring 3 is located in the sealing groove 24. The snap ring 3 is correspondingly arranged with the sealing groove 24. The rubber ring 31 is sleeved in the sealing groove 24. One side of the rubber ring 31 contacts the pipe joint 1, and the other side of the rubber ring 31 contacts the snap ring 3.

[0035] Furthermore, the sealing groove 24 provided on the connecting pipe 2 is a special groove for installing the sealing assembly 15. The sealing assembly 15 is composed of a snap ring 3 and a rubber ring 31. The snap ring 3 is used to fix the rubber ring 31 and provide additional support. The rubber ring 31 directly contacts the pipe joint 1 to form a sealing interface. The two snap rings 3 are installed by splicing and fastening. The snap blocks 32 are inserted into the limiting grooves 33 to ensure the stable connection of the snap ring 3 and improve the sealing performance of the fluidizer.

[0036] Furthermore, the rubber ring 31, as the main sealing element, has good elasticity and sealing performance, and can effectively prevent air or material leakage. The splicing and fastening design of the snap ring 3 ensures the stable installation of the rubber ring 31 and prevents it from falling off or shifting during use.

[0037] Specifically, the silicone air disc 4 is set as a frustum. A connecting sleeve 41 is provided at the upper end of the silicone air disc 4. An air cavity 42 is formed on the silicone air disc 4. A central control area is formed in the air cavity 42. An annular sleeve 43 is arranged inside the air cavity 42.

The lower end of the silicone air disc 4 contacts the inner wall of the bin pump, and the lower end of the annular sleeve 43 contacts the pipe joint 1.

[0038] Further, the silicone air disc 4 is in the shape of a frustum, enabling a more uniform air flow distribution when air passes through. The diameter of the upper end of the frustum is smaller, and the diameter of the lower end is larger, allowing the air flow to gradually spread when passing through the silicone air disc 4, forming a broader air flow coverage area.

[0039] Further, the frustum shape helps to optimize the air flow distribution, enabling air to penetrate the material more evenly and improving the fluidization effect. At the same time, it enhances the structural stability of the silicone air disc 4, enabling it to maintain its shape under vibration or air flow impact.

[0040] Further, the swaying motion of the annular sleeve 43 can generate tiny air flow fluctuations, which help to break the adhesion force between material particles and promote the flow and dispersion of the material.

[0041] Working principle: Weld the pipe joint 1 on the side wall of the bin pump where the fluidizer needs to be installed. Then penetrate the fluidizer through the pipe joint 1. Set a thread at the end of the fluidizer. Then, through the compression nut 26, install the sealing ring 25 and the snap ring 3 in the sealing groove 24 in sequence, thereby fixing the fluidizer on the pipe joint 1. Then connect the fluidization inlet pipe to the pipe joint 1 through the pipe clamp 13. The welded pipe joint 1 and the pipe clamp 13 at the end of the pipe joint 1 can enhance the connection stability with the bin pump, thus preventing leakage and loosening problems.
