Description

Technical Field

[0001] The invention relates to the technical field of molecular sieves, in particular to a molecular sieve activation device. Background Art

[0002] Molecular sieve is a synthetic hydrated aluminosilicate zeolite with the function of screening molecules. After the molecular sieve is activated at high temperature and loses water, many micropores with uniform pore size are formed inside the crystal. It has the advantages of high adsorption capacity, strong selectivity, and high temperature resistance. Molecular sieve needs to be dried at high temperature and reactivated before it can be used repeatedly.

[0003] In this regard, the Chinese utility model patent with publication number CN212069431U proposes a heating device for activating molecular sieves, which is applied in the technical field of molecular sieve processing and solves the technical problems of uneven drying efficiency and low drying efficiency of molecular sieves. The key points of its technical solution include: a bracket, an insulation box installed on the bracket, and a drum rotatably arranged in the insulation box, the two ends of the drum respectively extend out of the two side end walls of the insulation box, the two side end walls of the drum are respectively provided with a feed port and a discharge port, the inner wall of the insulation box and the outer wall of the drum enclose an insulation space, the inner wall of the drum is provided with an evacuation piece for facilitating the output of the molecular sieve to the discharge port, the outer wall of the insulation box is installed with a constant temperature heating component for heating the insulation space, and the bracket is provided with a driving component for driving the drum to rotate.

[0004] However, the existing activation devices including the above patents have the following problems: when working, the evacuation parts are driven by the rotation of the drum to stir the molecular sieve. During this process, the evacuation parts will bring the molecular sieve to a certain height and then lift it up to stir the molecular sieve. However, during this process, the molecular sieve will fall from a high place and hit the bottom of the drum. After multiple collisions, the molecular sieve is easily damaged, affecting the yield rate of the molecular sieve after drying. On the other hand, the traditional drum-type molecular sieve drying equipment can only transport the molecular sieve in one direction, resulting in a long drum length and a large overall equipment footprint.

This arrangement can effectively protect the molecular sieve. When the drum rotates and turns over the molecular sieve in the first activation space, the molecular sieve will only move in the narrow first activation space and will not be driven to a high place by the stirring blades and then lifted up and dropped from a high place, which is not easy to cause damage to the molecular sieve and avoids damage to the molecular sieve due to falling from a high place. On the other hand, the narrow first activation space can also turn over the molecular sieve. Better spread it out to avoid the accumulation of molecular sieves that affects the quality and efficiency of drying and activation. A secondary activation space with the opposite direction of travel is set outside the first activation space, which can perform secondary activation of the molecular sieve, make full use of thermal energy, improve the drying effect, and effectively reduce the length of the drum and reduce the volume occupied by the equipment. After the molecular sieve is fed into the first activation space from the feeding port, it is transported in the first activation space in the direction away from the feeding port. When it is transported to the end of the first activation space, it enters the secondary activation space outside the first activation space. The secondary activation space transports the molecular sieve to the other end until the molecular sieve is output through the discharge port. The secondary drying and activation effect is better.

In this embodiment, the drum 2 is arranged as a sandwich structure, and the first activation space 23 for conveying the molecular sieve and drying and activating is arranged between the first cylinder 21 and the second cylinder 22. This arrangement can effectively protect the molecular sieve. When the drum 2 rotates and turns the molecular sieve in the first activation space 23, the molecular sieve will only move in the narrow first activation space 23 and will not be driven to a high place by the stirring equipment and then lifted up and dropped from a high position. In this embodiment, even if the molecular sieve is brought to a high place by the stirring blades and falls, it will only fall on the outer wall of the first cylinder 21, and will not cause damage to the molecular sieve, thereby avoiding damage to the molecular sieve due to falling from a high place. On the other hand, the narrow first activation space 23 can also spread the molecular sieve better, thereby avoiding the accumulation of molecular sieves that affects the quality and efficiency of drying and activation.

[0034] See also Figure 3 , Figure 4 , Figure 5 and Figure 6On the basis of Example 1, in order to solve the problem that the traditional drum-type molecular sieve drying equipment can only transport molecular sieves in one direction, resulting in a long drum length and a large footprint, the drum 2 of this embodiment also includes a third cylinder 25 arranged outside the second cylinder 22, and a secondary activation space 26 is provided between the third cylinder 25 and the second cylinder 22, and the secondary activation space 26 is connected to the first activation space 23 at one end away from the feeding port 11, and a first baffle plate 27 is provided at one end of the first cylinder 21 and the third cylinder 25 away from the feeding port 11, and a discharge port 12 connected to the secondary activation space 26 is provided on the chassis 1 near the lower side of the feeding port 11. In this embodiment, a secondary activation space 26 is set outside the first activation space 23, which can perform secondary activation on the molecular sieve, make full use of thermal energy, improve the drying effect, and effectively reduce the length of the drum and reduce the volume occupied by the equipment. After the molecular sieve is fed into the first activation space 23 from the feeding port 11, it is transported in the first activation space 23 in a direction away from the feeding port 11. When it is transported to the end of the first activation space 23, it enters the secondary activation space 26 outside the first activation space 23. The secondary activation space 26 transports the molecular sieve to the other end until the molecular sieve is output through the discharge port 12. The secondary drying and activation effect is better.

[0035] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 The outer wall of the first cylinder 21 is provided with a first conveying blade 28 for pushing the material in the first activation space 23 away from the feeding port 11, and the inner wall of the third cylinder 25 is provided with a second conveying blade 29 for conveying the material in the secondary activation space 26 toward the discharge port 12. The first conveying blade 28 and the second conveying blade 29 control the traveling direction of the molecular sieve so that it can travel along a predetermined route.

[0036] See also Figure 4 and Figure 5 The first conveying blade 28 is fixed on the first cylinder 21, and the second conveying blade 29 is fixed on the third cylinder 25. The first cylinder 21 and the third cylinder 25 are fixedly connected and driven by a driving mechanism to keep synchronous rotation. A set of driving mechanisms can drive the first cylinder 21 and the third cylinder 25 to rotate synchronously, and drive the first conveying blade 28 and the second conveying blade 29 to convey synchronously, thereby reducing costs and improving synchronization.

[0038] See also Figure 3 The end of the third cylinder 25 close to the discharge port 12 is retracted relative to the second cylinder 22 to form an activation output port 212 for discharging the material in the secondary activation space 26. The upper end of the discharge port 12 is provided with a collecting hopper for cooperating with the activation output port 212. This arrangement is convenient for discharging. When the material in the secondary activation space 26 is transported toward the discharge port 12, it can fall into the collecting hopper below through the activation output port 212 and then be discharged through the discharge port 12, making discharging more convenient.

[0039] See also Figure 4 The driving mechanism includes a driving motor 4, an annular gear ring 5, a plurality of annular support rails, a plurality of track wheels matched with the annular support rails, and a mounting bracket arranged in the chassis 1. The outer wall of the third cylinder 25 is provided with an annular gear ring 5 coaxially arranged therewith. The chassis 1 is provided with a driving motor 4 for driving the annular gear ring 5 to rotate. The first cylinder 21 is fixedly connected with the third cylinder 25 and keeps synchronous rotation, and the second cylinder 22 remains stationary. The driving motor 4 cooperates with the annular gear ring 5 to drive the third cylinder 25 and the first cylinder 21 to rotate synchronously, and the first conveying blade 28 is arranged on the first cylinder 21, and the second conveying blade 29 is arranged on the inner wall of the third cylinder 25. When the first cylinder 21 and the third cylinder 25 rotate, they can be conveyed simultaneously through the conveying blades. A set of driving motors can simultaneously drive the first cylinder 21 and the third cylinder 25 to rotate synchronously to flip the internal molecular sieve, and at the same time drive the conveying blades to convey, so as to reasonably use the driving structure and save costs.

[0041] See also Figure 4 The inner wall of one end of the second cylinder 22 near the feeding port 11 is provided with a plurality of second support rollers 214 for cooperating with the outer wall of the first cylinder 21. The second support rollers 214 are used to support the end of the first cylinder 21 to prevent the first cylinder 21 from bending and deforming under the action of gravity.

[0042] Preferably, the first support roller 213 and the second support roller 214 are both covered with a protective cover, and the gap between the protective cover and the cylinder is smaller than the particle size of the molecular sieve to be activated. The protective cover can prevent the molecular sieve from entering between the roller and the cylinder, prevent the molecular sieve from being crushed during operation, and can also protect the roller.

The molecular sieve is dried and activated by hot air, which is efficient and uniformly heated. The hot air pipe 31 is inserted into the first cylinder 21, and hot air is emitted from the inside of the first cylinder 21 to the outside, which can heat the first activation space 23 and the secondary activation space 26 uniformly in the circumferential direction, with high heating efficiency and full use of heat energy.

[0044] See also Figure 3 , Figure 5 The side wall of the hot air pipe 31 is provided with a plurality of hot air output holes 311 communicating with the inside thereof, wherein the density of the hot air output holes 311 at the lower side of the hot air pipe 31 is greater than the density of the hot air output holes 311 at the upper side of the hot air pipe 31. The hot air pipe 31 is provided with hot air output holes 311 in the circumferential direction, and the drum 2 can be heated in the circumferential direction. The molecular sieves at the lower side of the drum 2 will accumulate due to gravity, so more hot air output holes 311 are provided at the lower side of the hot air pipe 31 to increase the air volume at the lower side, and the hot air distribution is more reasonable.

[0048] Specifically, a number of stirring blades (not shown in the figure) are also provided in the first activation space 23 and the secondary activation space 26. The stirring blades are arranged on the barrel walls of the first barrel 21, the second barrel 22, and the third barrel 25, and are used to assist in stirring and turning the molecular sieve in the activation space when the barrel rotates.

[0050] Preferably, on the basis of Embodiment Two, an exhaust duct communicating with the exhaust port 14 is provided on the chassis 1. The output end of the exhaust duct separates the water in the air after passing through a gas-liquid separation device, and then conveys the hot air to the air input end of the hot air blower 3 to preheat the inlet air of the hot air blower 3 (not shown in the figure). An induced draft fan for introducing the air in the chassis 1 into the exhaust duct is provided on the exhaust duct. The discharged hot air can be reused, saving energy and making full use of the heat energy.

[0051] Refer to Figure 3 , a screw conveyor is provided between the feeding port 11 and the first activation space 23. The feeding through the screw conveyor has stronger controllability, which is convenient for controlling the feeding speed and the feeding amount.

[0052] Working process of the present invention:

[0053] During the working process of a molecular sieve activation device of the present invention, the molecular sieve is put into the first activation space 23 through the feeding port 11. When the first barrel 21 and the third barrel 25 rotate, the first conveying blade 28 is driven to rotate at the same time. The first conveying blade 28 conveys the molecular sieve in the first activation space 23 in a direction away from the feeding port 11 until the molecular sieve is sent into the secondary activation space 26 communicating therewith. The second conveying blade 29 in the secondary activation space 26 conveys the molecular sieve in the direction of the discharge port 12 until the molecular sieve falls into the discharge port 12 through the activation outlet 212 and is discharged from the discharge port 12. When the molecular sieve is in the drum 2, the drying mechanism continuously diverges the hot air from the center of the first barrel 21 to the outside, so as to dry and activate the molecular sieve in the circumferential direction of the first activation space 23 and the secondary activation space 26.
