Description

Technical Field

[0001] The present invention relates to the technical field of drying devices, and more particularly, to a molecular sieve activation tower. Background Art

[0002] A molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite with a molecular sieving effect. It has many uniformly sized pores and neatly arranged cavities in its structure. Molecular sieves with different pore diameters separate molecules of different sizes and shapes, so it is called a molecular sieve, but its morphology is mostly spherical.

[0003] Most of the molecular sieves are spherical in shape. After being prepared by a granulator or a spheroidizer, they need to be activated, that is, the moisture inside is evaporated in a high-temperature environment. Usually, a drying oven or a drying tower is used to remove the moisture inside the molecular sieve by high temperature. However, since the particle size of the molecular sieve is very small (millimeter level), the molecular sieves are densely packed. When the moisture inside the molecular sieve is removed, it cannot be quickly discharged, resulting in the accumulation of moisture inside the molecular sieve. The accumulation of a large amount of moisture will affect the morphology of the molecular sieve, affecting the shape and pores of the molecules. Therefore, a more efficient molecular sieve activation device can be designed. Summary of the Invention

In this way, multiple molecular sieves with different parameters can be efficiently processed simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment

[0030] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 6As shown in the figure, the molecular sieve activation tower of this embodiment includes an outer tube 11 arranged obliquely, an inner tube 21 fixedly arranged inside the outer tube 11, a bracket for supporting the outer tube 11, a first driving device for driving the outer tube 11 to rotate, a plurality of partitions 22 arranged inside the inner tube 21 along the length direction of the inner tube 21, a plurality of first heating boxes 25 arranged outside the inner tube 21, and a plurality of second heating boxes 26 arranged outside the inner tube 21; the partitions 22 divide the interior of the inner tube 21 into a plurality of chambers, and along the length direction, the plurality of chambers are divided into alternately arranged first chambers 23 and second chambers 24; the first heating boxes 25 are used to connect adjacent first chambers 23; the second heating boxes 26 are used to connect adjacent second chambers 24; a driving rod 31 is arranged inside the inner tube 21, the driving rod 31 is fixedly connected to the partition 22, a gas guide cavity 32 is arranged at the part where the driving rod 31 is connected to the partition 22, a plurality of air permeable holes 33 are opened on the side wall of the gas guide cavity 32, and a gas supply device is connected to one end of the driving rod 31; air permeable holes 33 are arranged on both sides of the partition 22. Specifically, when in use, the molecular sieves are respectively put into the uppermost first chamber 23 and second chamber 24, the molecular sieves are preheated in the first chamber 23 and the second chamber 24, and after a period of time, the molecular sieves in the first chamber 23 and the second chamber 24 are respectively sent into the first heating box 25 and the second heating box 26 to quickly heat the molecular sieves. After a period of time, the molecular sieves in the first heating box 25 and the second heating box 26 are respectively sent into the lower first chamber 23 and second chamber 24, and high-temperature and high-pressure air is sent into the gas guide cavity 32 of the driving rod 31 through the gas supply device. The high-temperature air enters the chamber through the air permeable holes 33 above the partition 22, passes through the molecular sieves and takes away the moisture on the surface of the molecular sieves, and then enters the air permeable cavity through the air permeable holes 33 below the partition 22 (the first driving device drives the inner tube 21 and the outer tube 11 to rotate as a whole, which can make the molecular sieves rotate and mix evenly in the chamber, the first heating box 25 and the second heating box 26), and then enters the upper chamber through the air permeable holes 33 above again. In this way, the high-temperature air takes away the moisture on the surface of the molecular sieves in the chamber after passing through a plurality of chambers in turn. And the molecular sieves in the first chamber 23 and the first heating box 25 are independently circulated with the molecular sieves in the second chamber 24 and the second heating box 26. Therefore, molecular sieves with different parameters can be placed in the same activation tower for activation treatment. In addition, when the molecular sieves are activated, they will pass through the first chamber 23 (or the second chamber 24) in turn to take away the moisture on their surfaces, and then pass through the first heating box 25 (or the second heating box 26) to heat the molecular sieves to a high temperature to disperse the moisture inside. In this way, molecular sieves with multiple parameters can be processed efficiently at the same time. It should be noted that the gas supply device is mainly an air compressor and a gas heating device. The air compressor sends high-temperature air into the gas guide cavity 32 of the driving rod 31 through the gas supply pipe 17, and the end of the gas supply pipe 17 is rotatably connected to the driving rod 31.

[0031] In the present embodiment, heating wires are provided in both the first heating box 25 and the second heating box 26. A first feed pipe 27 is provided at the upper end of the first heating box 25, and a first discharge pipe 28 is provided at the lower end of the first heating box 25. The first feed pipe 27 communicates with the side wall at the lower end of the first chamber 23, and the first discharge pipe 28 communicates with the side wall at the upper end of the adjacent lower first chamber 23. A second feed pipe 29 is provided at the upper end of the second heating box 26, and a second discharge pipe 210 is provided at the lower end of the second heating box 26. The second feed pipe 29 communicates with the side wall at the lower end of the second chamber 24, and the second discharge pipe 210 communicates with the side wall at the upper end of the adjacent lower second chamber 24. Specifically, the first heating box 25 and the second heating box 26 are used to heat the molecular sieve to a high temperature, which can use electricity or open fire for heating. Among them, the outer tube 11 can play a heat preservation role. The material in the first chamber 23 enters the first heating box 25 through the first feed pipe 27, and the material in the first heating box 25 is discharged into the lower first chamber 23 through the first discharge pipe 28. The same applies to the second chamber 24 and the second heating box 26.

[0032] In the present embodiment, the first heating box 25 and the second heating box 26 are respectively located on opposite sides of the inner tube 21. Specifically, this can better install the first heating box 25, the second heating box 26, and connect pipelines such as the first feed pipe 27, the second feed pipe 29, the first discharge pipe 28, and the second discharge pipe 210.

[0033] In the present embodiment, the first chamber 23 at the uppermost end is connected to a first main feed pipe 214, and the second chamber 24 at the uppermost end is connected to a second main feed pipe 213; the first chamber 23 at the lowermost end is connected to a first main discharge pipe 216, and the second chamber 24 at the lowermost end is connected to a second main discharge pipe 215. A first blocking pipe 218 is threadedly connected inside the first main discharge pipe 216; one end of the first blocking pipe 218 is provided inside the first chamber 23; a second blocking pipe 217 is threadedly connected inside the second main discharge pipe 215; one end of the second blocking pipe 217 is provided inside the second chamber 24. Multiple scraping plates 34 are provided on the side wall of the driving rod 31; scraping plates 34 are provided in each chamber. Specifically, setting the first blocking pipe 218 in the first main discharge pipe 216 can not only block the first main discharge pipe 216, but also prevent the material from entering the first main discharge pipe 216 in advance. The same applies to the second main discharge pipe 215. Setting the scraping plates 34 on the side wall of the driving rod 31 can better stir the material, making it more evenly contact with the hot air.

[0034] The first driving device in this embodiment includes a first motor 15 and a first transmission belt 16 for connecting the output shaft of the first motor 15 to the outer wall of the outer tube 11. Specifically, the first motor 15 drives the outer tube 11 to rotate through the first transmission belt 16, thereby driving all components inside the outer tube 11 to rotate synchronously. The outer tube 11 and the inner tube 21 can be connected by a connecting rod. The first transmission belt 16 can also be replaced with a sprocket structure.

[0035] A ring-shaped baffle 211 is provided below the partition 22 in this embodiment, and a feed hole 212 is formed in the side wall of the baffle 211; the driving rod 31 is connected to a second driving device for driving the driving rod 31 to rotate; the feed hole 212 corresponding to the first discharge pipe 28 is the first feed hole, and the feed hole 212 corresponding to the second discharge pipe 210 is the second feed hole; multiple first feed holes are not connected to the first discharge pipe 28 at the same time, and multiple second feed holes are not connected to the second discharge pipe 210 at the same time; adjacent first feed holes and second feed holes are respectively connected to the first discharge pipe 28 and the second discharge pipe 210 at the same time. Specifically, when the feed hole 212 on the baffle 211 is not connected to the first discharge pipe 28 (or the second discharge pipe 210), the material in the first heating box 25 (or the second heating box 26) cannot be discharged, and since the first heating box 25 (or the second heating box 26) is full of material, the material in the first chamber 23 (or the second chamber 24) cannot enter the first heating box 25 (or the second heating box 26) through the first feed pipe 27 (or the second feed pipe 29) either. When the material needs to move, the driving rod 31 can be rotated, thereby rotating the partition 22 and the baffle 211, so that the feed hole 212 on the baffle 211 is connected to the first discharge pipe 28 (or the second discharge pipe 210). At this time, the material can enter the first chamber 23 (or the second chamber 24) through the feed hole 212. At the same time, since the material in the first heating box 25 (or the second heating box 26) is discharged, the material in the upper first chamber 23 (or the second chamber 24) can enter the first heating box 25 (or the second heating box 26) through the first feed pipe 27 (or the second feed pipe 29). By adjusting the positions of the feed holes 212 on each baffle 211, the orderly flow of the material can be adjusted by rotating the driving rod 31.

[0036] The second driving device in this embodiment includes a second transmission belt 36 connected to the end of the driving rod 31 away from the air supply device and a second motor 35 connected to the second transmission belt 36. Specifically, the second motor 35 drives the driving rod 31 to rotate through the second transmission belt 36. A sprocket or gear transmission can also be used.

[0037] The bracket in this embodiment includes a bottom plate 14, a plurality of fixing rings 12 sleeved on the outer wall of the outer tube 11, and support columns 13 for connecting the fixing rings 12 and the bottom plate 14; the outer tube 11 is rotatably connected to the fixing rings 12.

[0038] In summary, in the molecular sieve activation tower of this embodiment, when in use, the molecular sieves are respectively put into the uppermost first chamber 23 and second chamber 24, and the molecular sieves are preheated in the first chamber 23 and the second chamber 24. After a period of time, the molecular sieves in the first chamber 23 and the second chamber 24 are respectively sent into the first heating box 25 and the second heating box 26 to quickly heat the molecular sieves. After a period of time, the molecular sieves in the first heating box 25 and the second heating box 26 are respectively sent into the lower first chamber 23 and second chamber 24, and high-temperature and high-pressure air is sent into the air guide chamber 32 of the driving rod 31 through the air supply device. The high-temperature air enters the chamber through the air permeable holes 33 above the partition plate 22, passes through the molecular sieves and takes away the moisture on the surface of the molecular sieves, and then enters the air permeable chamber through the air permeable holes 33 below the partition plate 22 (the first driving device drives the overall rotation of the inner tube 21 and the outer tube 11, which can make the molecular sieves rotate and mix evenly in the chamber, the first heating box 25 and the second heating box 26), and then enters the upper chamber through the air permeable holes 33 above again. In this way, the high-temperature air takes away the moisture on the surface of the molecular sieves in the chamber after passing through multiple chambers in sequence. And the molecular sieves in the first chamber 23 and the first heating box 25 are independently circulated from the molecular sieves in the second chamber 24 and the second heating box 26. Therefore, molecular sieves with different parameters can be placed in the same activation tower for activation treatment. In addition, when the molecular sieves are activated, they will pass through the first chamber 23 (or the second chamber 24) in sequence to take away the moisture on their surfaces, and then pass through the first heating box 25 (or the second heating box 26) to heat the molecular sieves to a high temperature to disperse the moisture inside. In this way, multiple molecular sieves with different parameters can be processed efficiently at the same time.

[0039] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
