[0002] Fluidized bed is a technology that uses gas or liquid to fluidize solid particles. It is widely used in the chemical, energy and materials fields. In order to obtain the sample raw material conditions, it is necessary to use sampling devices or fixed-point sampling to analyze particle characteristics, reaction progress and product quality, provide data support for process optimization and control, and ensure stable system operation and product consistency.

[0003] Although the existing sampling structure can meet the requirements of quantitative sampling, it is still easy to fill the sampling slot after the sampling piece enters the cylinder body.

For this reason, an anti-overflow online sampling structure is proposed. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0024] Example 1 See also Figure 1-Figure 5 As shown, in this embodiment, an overflow-proof online sampling structure is provided, comprising: a sampling tube 2 fixed to one side of the cylinder body 1, a sampling port connected to the cylinder body 1 is opened at one end of the sampling tube 2, a sampling head 5 is slidably connected in the sampling port, the sampling head 5 is adapted to the inner circumference of the sampling port and forms a sealed fit, a storage groove 6 is opened on the circumference of the sampling head 5, and a first air bag 7 for adjusting the space in the storage groove 6 is fixedly connected to the inner wall of the storage groove 6 away from the open end. When sampling, the first air bag 7 expands to reduce the volume in the storage groove 6, and then the first air bag 7 is deflated, thereby enabling the height of the sample in the storage groove 6 to be lowered to avoid falling into the sampling port and causing wear on the sampling head 5 and the sampling port. A discharge pipe 11 is fixedly connected to the bottom of the sampling port, and a collecting bottle 12 is threadedly connected to the bottom of the discharge pipe 11. After sampling, the sampling head 5 is pulled out and the storage groove 6 is facing downward, thereby allowing the sample to slide into the collecting bottle 12 through the discharge pipe 11, and the collecting bottle 12 can be taken out by rotating the collecting bottle 12; A slideway 34 is provided at one end of the sampling tube 2 away from the sampling head 5, and a movable sleeve 3 is slidably connected in the slideway 34. A mounting hole is provided at one end of the movable sleeve 3, and a movable tube 8 is fixedly connected to one end of the mounting hole. The movable tube 8 slides through the sampling tube 2 and is fixed to the sampling head 5. The movable sleeve 3 drives the sampling head 5 to move axially along the sampling tube 2 and rotate around its own center through the movable tube 8. The movable sleeve 3 is moved, and the movable sleeve 3 drives the sampling head 5 to rotate through the movable tube 8, thereby causing the storage groove 6 to face upward, and then the movable sleeve 3 is pushed forward, so that the sampling head 5 extends into the cylinder body 1 for sampling; It also includes an inflation and deflation assembly, which is arranged at one end of the movable sleeve 3 to expand or contract the first airbag 7; The device further comprises a vibration mechanism 13 , which is arranged at the bottom of the sampling tube 2 and is used to discharge the material from the discharge tube 11 .

[0025] In the present invention, one end of the movable sleeve 3 is fixedly connected to a handle 4 , and the handle 4 and the notch orientation of the storage slot 6 are mapped to the same position in the radial direction, thereby facilitating the staff to understand the notch orientation of the storage slot 6 .

[0026] In particular, the inflation and deflation assembly includes a second airbag 15, which is fixed on one side of the handle 4. A connecting pipe 9 is fixedly connected between the second airbag 15 and the first airbag 7, and the connecting pipe 9 passes through the movable tube 8. A pressure plate 16 is bonded to one side of the second airbag 15, and two slide rods 17 are fixedly connected to one side of the pressure plate 16. Two avoidance holes 19 are provided in the middle of the second airbag 15, and the slide rods 17 pass through the avoidance holes 19 and slide through the handle 4 respectively. The circumference of the slide rod 17 is sleeved with a second spring 18, and the two ends of the second spring 18 are respectively in contact with the pressure plate 16 and the handle 4 through the spring seat. Pressing the pressure plate 16 squeezes the second airbag 15, and then squeezes the air in the second airbag 15 into the first airbag 7. Release the pressure plate 16, and the pressure plate 16 is reset under the action of the second spring 18, so that the second airbag 15 can expand and the first airbag 7 can shrink, thereby preventing the sample stack from overflowing.

[0027] It should be noted that the circumferential sleeve of the movable tube 8 is provided with a first spring 10, and the two ends of the first spring 10 are respectively in contact with the slide 34 and the mounting holes on the movable sleeve 3 through the spring seat, so that the first spring 10 facilitates the resetting of the movable sleeve 3.

[0028] Example 2 Improvements based on Example 1: Refer to the attached Figure 1-Figure 5 .

[0029] In the present invention, an annular blowing ring 31 is fixedly connected to the inner wall of the cylinder body 1. The blowing ring 31 is located at the connection point between the sampling tube 2 and the cylinder body 1. The inner wall of the blowing ring 31 is provided with an annular blowing port 32 for guiding air to blow toward the sampling head 5. After passing through the blowing ring 31, the air is blown toward the sampling head 5 through the blowing port 32, thereby reducing dust adhering to the surface of the sampling head 5 and improving the service life of the sampling head 5 and the sealing of the product.

[0030] In particular, an air passage 29 connected to the sampling port is opened on one side of the sampling tube 2, and a one-way air inlet valve 30 is fixedly installed at one end of the air passage 29. A penetrating air pipe 14 is fixedly connected to one side of the cylinder body 1, and one end of the air pipe 14 is fixedly connected to the blowing ring 31. The other end of the air pipe 14 is fixedly connected to the air passage 29 and a one-way air outlet valve 33 is installed on one side of the air pipe 14. When the sampling head 5 is pulled out, the sampling head 5 slides in the sampling port, and then blows the air in the sampling port to the blowing ring 31 through the air pipe 14.

[0031] It should be noted that the vibration mechanism 13 includes a guide block 24, which is fixed at the bottom of the sampling tube 2, and a driving rod 25 is slidably connected to one side of the guide block 24. One end of the driving rod 25 is fixedly connected to a fixing ring 27, which is sleeved on the circumference of the discharge tube 11, and one side of the fixing ring 27 is fixedly connected to a knocking block 28 that contacts the discharge tube 11. A tension spring 26 is installed between the driving rod 25 and the guide block 24 through a hook, and the knocking block 28 is moved away from the discharge tube 11. Then the driving rod 25 is released, and the driving rod 25 is quickly reset under the action of the tension spring 26, so that the knocking block 28 knocks the discharge tube 11, thereby avoiding the adhesion of raw material powder to the discharge tube 11, reducing waste, and reducing the possibility of cross contamination.

[0032] In the present invention, the vibration mechanism 13 also includes a rotating shaft 20, which is rotatably connected to the bottom of the sampling tube 2. The circumference of the rotating shaft 20 is fixedly connected to a push plate 22, and the circumference of the push plate 22 is provided with a plurality of triangular drive openings 23. One end of the drive rod 25 is rotatably connected to a roller, and the roller is used in conjunction with the push plate 22. The circumference of the rotating shaft 20 is fixedly connected to two knobs 21, and the two knobs 21 are respectively located above and below the push plate 22. When the knob 21 is manually turned, the knob 21 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the push plate 22 to rotate, thereby pushing the drive rod 25 to move through the drive opening 23.

[0033] The use process and working principle of the technical solution of the present invention are as follows: when sampling, the movable sleeve 3 is rotated by the handle 4, and the movable sleeve 3 drives the sampling head 5 to rotate through the movable tube 8, thereby making the storage groove 6 face upward, and then the movable sleeve 3 is pushed forward, thereby making the sampling head 5 extend into the cylinder body 1 for sampling. After sampling, the sampling head 5 is reset, and the storage groove 6 is facing downward, thereby making the sample slide into the collection bottle 12 through the discharge pipe 11, and the collection bottle 12 is rotated to take out the sample; When sampling, the pressing plate 16 is pressed, and the pressing plate 16 squeezes the second airbag 15, and then squeezes the air in the second airbag 15 into the first airbag 7, reducing the space in the storage tank 6. After sampling, the pressing plate 16 is released, which can shrink the first airbag 7, thereby reducing the sample in the storage tank 6, avoiding the pile-up entering the sampling port during sampling and causing wear and tear on the sampling head 5 and the sampling port, thereby improving the service life of the sampling structure; When the sampling head 5 is pulled out, the sampling head 5 slides in the sampling port, and then blows the air in the sampling port to the blowing ring 31 through the air pipe 14. The blowing ring 31 blows to the sampling head 5 through the blowing port 32, reducing the dust adhering to the surface of the sampling head 5, thereby improving the service life of the sampling head 5 and the sealing performance of the product; Before removing the collecting bottle 12, manually turn the knob 21, the knob 21 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the pushing plate 22 to rotate, and then pushes the driving rod 25 to move through the driving port 23. The driving rod 25 drives the knocking block 28 away from the discharge pipe 11 through the fixing ring 27, and then the driving rod 25 is quickly reset under the action of the tension spring 26, so that the knocking block 28 knocks the discharge pipe 11, avoiding the raw material powder from adhering to the discharge pipe 11, reducing waste, and reducing the possibility of cross contamination.
