Description

Technical Field

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

[0002] A 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 sizes are formed inside the crystal, which has the advantages of high adsorption capacity, strong selectivity, and high temperature resistance. The molecular sieve needs to be dried at high temperature and reactivated for repeated use.

[0003] In this regard, the Chinese utility model patent with the publication number CN212069431U proposes a heating device for molecular sieve activation, 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 the molecular sieve. The key points of its technical solution include: a bracket, a heat preservation box installed on the bracket, a drum rotatably arranged in the heat preservation box, both ends of the drum extend out of the two side end walls of the heat preservation box respectively, a feed port and a discharge port are respectively arranged on the two side end walls of the drum, a heat preservation space is enclosed between the inner wall of the heat preservation box and the outer wall of the drum, a dispersing member for facilitating the output of the molecular sieve to the discharge port is arranged on the inner wall of the drum, a constant temperature heating component for heating the heat preservation space is installed on the outer wall of the heat preservation box, and a driving component for driving the drum to rotate is arranged on the bracket.

[0004] However, the problem of the existing activation devices including the above patent is that during operation, the dispersing member drives the molecular sieve to rotate by rotating the drum. During this process, the dispersing member will bring the molecular sieve to a certain height and then lift it 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 impacts, the molecular sieve is easily damaged, affecting the yield of the dried molecular sieve; on the other hand, the traditional drum-type molecular sieve drying equipment can only convey the molecular sieve unidirectionally, resulting in a relatively long length of the drum and a large overall floor area of the equipment.

[0017] Advantages of a molecular sieve activation device of the present invention: By setting the drum as a sandwich structure, the first activation space for transporting and drying / activating the molecular sieve and the secondary activation space are respectively arranged between the first cylinder body and the second cylinder body, and between the second cylinder body and the third cylinder body. This setting method can effectively protect the molecular sieve. When the drum rotates to turn the molecular sieve in the first activation space, the molecular sieve will only move within the narrow first activation space and will not be driven by the stirring blades to a high place and then fall from a high position, which is not easy to cause damage to the molecular sieve and avoid damage to the molecular sieve due to falling from a high place. On the other hand, the narrow first activation space can also better spread out the molecular sieve to avoid the accumulation of the molecular sieve affecting the drying / activation quality and efficiency. A secondary activation space with an opposite traveling direction is arranged outside the first activation space, which can perform secondary activation on the molecular sieve, make full use of heat energy, improve the drying effect, and can effectively reduce the length of the drum and the floor area occupied by the equipment. When the molecular sieve is fed into the first activation space from the feeding port, it is transported in the first activation space in a 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, and the secondary activation space transports the molecular sieve to the other end until the molecular sieve is output through the discharge port, achieving better secondary drying / activation effect.

The drum 2 includes a first cylinder body 21 and a second cylinder body 22 sleeved outside the first cylinder body 21. The first cylinder body 21 and the second cylinder body 22 are coaxially arranged, and a first activation space 23 for the molecular sieve to pass through is provided between the first cylinder body 21 and the second cylinder body 22. A plurality of meshes for air to pass through are provided on the side walls of the first cylinder body 21 and the second cylinder body 22.

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 it is arranged between the first cylinder body 21 and the second cylinder body 22. This setting method 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 device and then fall from a high position. In this embodiment, even if the molecular sieve is brought to a high place and falls by the stirring blade, it will only fall on the outer wall of the first cylinder body 21, which will not cause damage to the molecular sieve and avoid 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, avoiding the accumulation of the molecular sieve and affecting the drying and activation quality and efficiency.

[0033] Embodiment 2:

[0034] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6, on the basis of the first embodiment, in order to solve the problem that traditional drum - type molecular sieve drying equipment can only convey molecular sieve unidirectionally, resulting in relatively long drum lengths and large floor areas, the drum 2 in this embodiment further includes a third cylinder body 25 arranged outside the second cylinder body 22. A secondary activation space 26 is provided between the third cylinder body 25 and the second cylinder body 22. One end of the secondary activation space 26 far from the feeding port 11 is communicated with the first activation space 23. And a first shielding plate 27 is provided at one end, far from the feeding port 11, between the first cylinder body 21 and the third cylinder body 25. An outlet 12 communicated with the secondary activation space 26 is provided on the chassis 1 near the lower side of the feeding port 11. In this embodiment, by arranging the secondary activation space 26 outside the first activation space 23, the molecular sieve can be secondarily activated, the heat energy can be fully utilized, the drying effect can be improved, and the length of the drum can be effectively reduced, and the floor area of the equipment can be reduced. When the molecular sieve is fed into the first activation space 23 from the feeding port 11, it is conveyed in the first activation space 23 in a direction away from the feeding port 11. When it is conveyed 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 conveys the molecular sieve to the other end until the molecular sieve is output through the outlet 12, and the secondary drying and activation have a better effect.

[0035] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , a first conveying blade 28 for pushing the material in the first activation space 23 in a direction away from the feeding port 11 is provided on the outer wall of the first cylinder body 21, and a second conveying blade 29 for conveying the material in the secondary activation space 26 in the direction of the outlet 12 is provided on the inner wall of the third cylinder body 25. By controlling the traveling direction of the molecular sieve through the first conveying blade 28 and the second conveying blade 29, it can travel along a predetermined route.

[0036] Refer to Figure 4 and Figure 5 , the first conveying blade 28 is fixed on the first cylinder body 21, the second conveying blade 29 is fixed on the third cylinder body 25, and the first cylinder body 21 and the third cylinder body 25 are fixedly connected and driven by a driving mechanism to rotate synchronously. Through a set of driving mechanisms, the first cylinder body 21 and the third cylinder body 25 can be driven to rotate synchronously, and the first conveying blade 28 and the second conveying blade 29 can be driven to convey synchronously, reducing costs and improving synchronism.

[0037] Refer to Figure 3, one end of the first cylinder 21 and the third cylinder 25 away from the feeding port 11 is fixedly connected through the first shielding disc 27. One end of the first cylinder 21 close to the feeding port 11 is provided with a third shielding disc 210. One end of the second cylinder 22 close to the feeding port 11 is provided with a second shielding disc 211. The second shielding disc 211 is fixedly connected to the inner wall of the chassis 1. One end of the first cylinder 21 close to the feeding port 11 is indented relative to the second cylinder 22. The center of the second shielding disc 211 is provided with a hollow opening 2111 for cooperating with the feeding port 11. The lower end of the feeding port 11 extends into the second cylinder 22 through the hollow opening 2111 and feeds materials into the first activation space 23.

[0038] Refer to Figure 3 , one end of the third cylinder 25 close to the discharge port 12 is indented relative to the second cylinder 22 to form an activation output port 212 for discharging the materials in the secondary activation space 26. The upper end of the discharge port 12 is provided with an aggregate hopper for cooperating with the activation output port 212. This setting method is convenient for discharging. When the materials in the secondary activation space 26 are conveyed towards the discharge port 12, they can fall into the lower aggregate hopper through the activation output port 212 and then be discharged through the discharge port 12, making the discharge more convenient.

[0039] Refer to 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 cooperating 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 with it. A driving motor 4 for driving the annular gear ring 5 to rotate is arranged in the chassis 1. The first cylinder 21 is fixedly connected to the third cylinder 25 and rotates synchronously. The second cylinder 22 remains stationary. The cooperation between the driving motor 4 and the annular gear ring 5 can drive the third cylinder 25 and the first cylinder 21 to rotate synchronously. 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 convey simultaneously through the conveying blades. One set of driving motor can drive the first cylinder 21 and the third cylinder 25 to rotate synchronously at the same time to turn the internal molecular sieve and drive the conveying blades to convey at the same time, making reasonable use of the driving structure and saving costs.

[0040] Refer to Figure 4, one end of the second cylinder body 22 close to the feeding port 11 is fixedly connected to the chassis 1, and the other end is provided with a plurality of first support rollers 213 arranged in a circular array on the outer wall of the second cylinder body 22. The other end of the first support roller 213 is in contact and cooperation with the inner wall of the third cylinder body 25. The first support roller 213 can be used to support the second cylinder body 22 to prevent the end of the second cylinder body 22 from bending and deforming under the action of gravity.

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

[0042] Preferably, a protective cover is sleeved outside both the first support roller 213 and the second support roller 214, and the gap between the protective cover and the cylinder body 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 body, prevent the molecular sieve from being crushed during operation, and can also protect the roller.

[0043] Refer to Figure 1 , Figure 3 and Figure 5 , the drying mechanism includes a hot air blower 3 arranged at the end of the chassis 1 away from the chassis 1 end, and a hot air pipe 31 arranged at the output end of the hot air blower 3. A through hole 271 for cooperating with the hot air pipe 31 is provided at the center of the first shielding disc 27, and the hot air pipe 31 extends into the first cylinder body 21 through the through hole 271. Using hot air to dry and activate the molecular sieve has high efficiency and uniform heating. Passing the hot air pipe 31 into the first cylinder body 21 and emitting hot air from the inside of the first cylinder body 21 can uniformly heat the first activation space 23 and the secondary activation space 26 in the circumferential direction, with high heating efficiency and full utilization of heat energy.

[0044] Refer to Figure 3 , Figure 5 , a plurality of hot air output holes 311 communicating with the inside thereof are provided on the side wall of the hot air pipe 31, and the density of the hot air output holes 311 on the lower side of the hot air pipe 31 is greater than the density of the hot air output holes 311 on the upper side of the hot air pipe 31. The hot air output holes 311 are provided circumferentially on the hot air pipe 31, and the drum 2 can be heated circumferentially. Since the molecular sieve accumulates on the lower side inside the drum 2 due to gravity, more hot air output holes 311 are provided on the lower side of the hot air pipe 31 to increase the air output on the lower side, and the hot air is more reasonably allocated.

[0045] Refer to Figure 1 , a plurality of exhaust ports 14 are provided on the chassis 1 for discharging waste gas.

[0046] Refer toFigure 1 , Figure 2 , Figure 7 The chassis 1 includes a lower box body 16 and an upper box body 17 arranged opposite to the lower box body 16, and one side of the upper box body 17 is hingedly connected to the lower box body 16. The upper box body 17 can be flipped open around the hinge position to facilitate maintenance of the internal drum 2 and other components.

[0047] Preferably, in order to facilitate opening of the upper box body 17 , the drum 2 , the driving mechanism, the drying mechanism and other components are detachably connected to the upper box body 17 .

[0048] Specifically, a plurality of stirring blades (not shown) are provided in the first activation space 23 and the secondary activation space 26. The stirring blades are provided on the walls of the first cylinder 21, the second cylinder 22 and the third cylinder 25 to assist in stirring and turning the molecular sieve in the activation space when the cylinders rotate.

[0049] Embodiment three:

[0050] Preferably, on the basis of the second embodiment, the chassis 1 is provided with an exhaust pipe connected to the exhaust port 14, the output end of the exhaust pipe separates the water in the air after passing through the gas-liquid separation device, and then the hot air is transported 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), and the exhaust pipe is provided with an induced draft fan for introducing the air in the chassis 1 into the exhaust pipe. The exhausted hot air can be reused for a second time, saving energy and making full use of heat energy.

[0051] See also Figure 3 A screw conveyor is provided between the feeding port 11 and the first activation space 23. The feeding through the screw conveyor is more controllable and convenient for controlling the feeding speed and feeding amount.

[0052] Working process of the present invention:

[0053] In the working process of the 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 cylinder 21 and the third cylinder 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 the direction away from the feeding port 11 until the molecular sieve is sent to the secondary activation space 26 connected thereto. The second conveying blade 29 in the secondary activation space 26 conveys the molecular sieve toward the discharge port 12 until the molecular sieve falls into the discharge port 12 through the activation output port 212 and is discharged from the discharge port 12. When the molecular sieve is in the drum 2, the drying mechanism continuously radiates hot air from the center of the first cylinder 21 to the outside, thereby drying and activating the molecular sieves in the circumferential direction of the first activation space 23 and the secondary activation space 26.
