Description

Technical Field

[0001] This utility model relates to the field of gas-solid phase reactor technology, specifically a gas-solid phase reactor. Background Technology

[0002] Gas-solid phase contact catalytic reaction is a reaction in which a gaseous mixture of reactants is passed through a solid catalyst at a certain temperature and pressure. A gas-solid phase reactor is the container in which this reaction takes place.

[0003] Existing examples include Chinese invention patent application number CN201922447280.1, which discloses a gas-solid phase reactor consisting of a cylinder, a rotating shaft, a cover plate, a catalytic structure, and a power unit. A solid catalyst is placed inside the catalytic structure, and gas enters from the inlet on the cover plate and exits from the outlet on the cover plate. As the usage time increases, the solid catalyst inside the catalytic structure becomes ineffective, causing the gas-solid phase reaction rate to slow down. At this time, the cover plate is opened, the catalytic structure is removed, and a spare catalytic structure filled with solid catalyst is directly replaced, thereby achieving the effect of improving the catalytic rate.

[0004] The existing reactors are driven by a motor to rotate the shaft directly. During use, there is a gap between the shaft and the cylinder, which makes it easy for gas to leak through the gap. Utility Model Content

[0005] To address the problems mentioned in the background art, the present invention aims to provide a gas-solid phase reactor that has the advantage of avoiding gas leakage. It solves the problem that existing reactors, which are driven by a motor to rotate the shaft, have gaps between the shaft and the cylinder, causing gas to easily leak through the gaps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: it includes a cylinder, a cover plate, an air inlet, an air outlet, and a bearing. The cover plate is located on the left side of the cylinder, the air inlet is located on the right side of the cylinder, the air outlet is located on the left side of the cover plate, the bearing is installed on the right side of the cover plate and the right side of the inner wall of the cylinder, a rotating shaft is provided on the inner wall of the cylinder, a catalytic device is installed on the surface of the rotating shaft, and a transmission mechanism is provided on the right side of the cylinder.

[0007] As a preferred embodiment of the present invention, the transmission mechanism includes a support ring, a motor is mounted on the right side of the support ring, a cylinder is mounted on the output end of the motor, and a permanent magnet is mounted on one side of the cylinder.

[0008] As a preferred embodiment of this invention, a second cylinder is mounted on the right side of the rotating shaft, and a second permanent magnet is mounted on one side of the second cylinder.

[0009] As a preferred embodiment of this utility model, a shielding cover is installed on the right side of the inner wall of the cylinder, and a fixing groove is provided on both sides of the rotating shaft, with a sealing ring installed on the inner wall of the fixing groove.

[0010] As a preferred embodiment of this invention, a flow guide shroud is provided inside the cylinder, and a sealing gasket is installed on the right side of the cover plate.

[0011] As a preferred embodiment of this invention, a fixing ring is provided on the left side of the cover plate.

[0012] As a preferred embodiment of this invention, the inner wall of the fixing ring is provided with screws.

[0013] As a preferred embodiment of this invention, a protrusion is installed on the left side of the cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a cover plate, can seal the left side of the cylinder to prevent gas leakage. At the same time, it can be opened when the catalytic device needs to be replaced, so that the rotating shaft can be taken out to replace the catalytic device. The bearing can support and limit the rotating shaft, and at the same time reduce the resistance when the rotating shaft rotates, making the rotating shaft rotate more smoothly. This solves the problem that existing reactors directly drive the rotating shaft to rotate through a motor, and there is a gap between the rotating shaft and the cylinder during use, which makes it easy for gas to leak through the gap. This invention has the advantage of preventing gas leakage.

[0016] 2. By setting up a transmission mechanism, the support ring can fix the motor and provide space for the cylinder to move, so as to avoid the cylinder being affected by external interference. The motor drives the cylinder to rotate, and the cylinder drives the permanent magnet to rotate. The permanent magnet and the permanent magnet attract each other, so that the permanent magnet drives the permanent magnet to rotate.

[0017] 3. By setting up a cylinder and a permanent magnet, the permanent magnet drives the cylinder to rotate, which in turn drives the shaft to rotate. This eliminates gaps during transmission, prevents gas leakage, and makes the transmission more stable. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, the present invention includes a cylinder 1, a cover plate 2, an air inlet 3, an air outlet 4, and a bearing 5. The cover plate 2 is located on the left side of the cylinder 1, the air inlet 3 is located on the right side of the cylinder, the air outlet 4 is located on the left side of the cover plate 2, the bearing 5 is installed on the right side of the cover plate 2 and the right side of the inner wall of the cylinder 1, a rotating shaft 6 is provided on the inner wall of the cylinder 1, a catalytic device 7 is installed on the surface of the rotating shaft 6, and a transmission mechanism 8 is provided on the right side of the cylinder 1.

[0024] refer to Figure 2 The transmission mechanism 8 includes a support ring 81, a motor 82 is mounted on the right side of the support ring 81, a cylinder 83 is mounted on the output end of the motor 82, and a permanent magnet 84 is mounted on one side of the cylinder 83.

[0025] As a technical optimization of this utility model, by setting a transmission mechanism 8, the support ring 81 can fix the motor 82 and at the same time provide space for the cylinder 83 to move, so as to avoid the cylinder 83 being affected by external interference. The motor 82 drives the cylinder 83 to rotate, and the cylinder 83 drives the permanent magnet 84 to rotate. The permanent magnet 84 and the permanent magnet 10 attract each other, so that the permanent magnet 84 can drive the permanent magnet 10 to rotate.

[0026] refer to Figure 2 A cylinder 2 9 is installed on the right side of the rotating shaft 6, and a permanent magnet 2 10 is installed on one side of the cylinder 2 9.

[0027] As a technical optimization of this utility model, by setting a cylinder 2 9 and a permanent magnet 2 10, the permanent magnet 2 10 drives the cylinder 2 9 to rotate, and the cylinder 2 9 drives the rotating shaft 6 to rotate, which can eliminate gaps during transmission, avoid gas leakage, and make the transmission more stable.

[0028] refer to Figure 2 A shielding cover 11 is installed on the right side of the inner wall of the cylinder 1, and a fixing groove 12 is provided on both sides of the rotating shaft 6. A sealing ring 13 is installed on the inner wall of the fixing groove 12.

[0029] As a technical optimization of this utility model, by setting a shielding cover 11, a fixing groove 12 and a sealing ring 13, the shielding cover 11 can shield the external magnetic force to avoid affecting the inside of the cylinder 1, and at the same time avoid affecting the magnetic force, making the transmission more stable. The fixing groove 12 can fix the sealing ring 13, and the sealing ring 13 can eliminate the gap between the rotating shaft 6 and the inner ring of the bearing 5, while increasing the friction with the inner ring of the bearing 5, making it easier to pull out and install when replacing the catalytic device 7.

[0030] refer to Figure 3 A flow guide shroud 14 is installed inside the cylinder 1, and a sealing gasket 15 is installed on the right side of the cover plate 2.

[0031] As a technical optimization of this utility model, by setting a flow guide shroud 14 and a sealing gasket 15, the flow guide shroud 14 can guide the gas when the catalytic device 7 rotates, preventing the gas from passing through the gap between the catalytic device 7 and the cylinder 1. The sealing gasket 15 can fill the gap between the cover plate 2 and the cylinder 1, improving the sealing effect and preventing the gas from escaping.

[0032] refer to Figure 3 A retaining ring 16 is provided on the left side of the cover plate 2.

[0033] As a technical optimization of this utility model, by setting a fixing ring 16, which is sleeved on the surface of the cover plate 2, the fixing ring 16 distributes the pressure evenly on the cover plate 2, avoiding the situation where the cover plate 2 is unevenly stressed and one end lifts up, which would affect the sealing effect.

[0034] refer to Figure 3 The inner wall of the retaining ring 16 is provided with screws 17.

[0035] As a technical optimization of this utility model, by setting screw 17, the fixing ring 16 is moved to the right to squeeze the cover plate 2, which makes it more convenient to fix the cover plate 2.

[0036] refer to Figure 3 A protrusion 18 is installed on the left side of the cylinder 1.

[0037] As a technical optimization of this utility model, by setting a protrusion 18, by rotating the screw 17, the screw 17 moves to the right side of the inner wall of the protrusion 18 under the push of the thread, and at the same time drives the fixing ring 16 to press the cover plate 2 to fix the cover plate 2.

[0038] The working principle and usage process of this utility model are as follows: During use, the cover plate 2 seals the left side of the cylinder 1 to prevent gas leakage. It can also be opened when the catalytic converter 7 needs to be replaced, allowing the rotating shaft 6 to be removed for replacement. The bearing 5 supports and limits the rotating shaft 6, reducing resistance during rotation and making it smoother. The support ring 81 fixes the motor 82 and provides space for the cylinder 83 to move, preventing external interference from affecting its transmission. The motor 82 drives the cylinder 83 to rotate, which in turn drives the permanent magnet 84 to rotate. The permanent magnet 84 and the permanent magnet 10 attract each other, causing the permanent magnet 84 to drive the permanent magnet 10 to rotate. The permanent magnet 10 then drives the cylinder 9 to rotate, which in turn drives the rotating shaft 6 to rotate. This process eliminates gaps during transmission, preventing gas leakage and ensuring greater stability. The shielding cover 11 shields the external magnetic force, preventing it from affecting the interior of the cylinder 1. To avoid affecting the magnetic force and make the transmission more stable, the fixing groove 12 can fix the sealing ring 13. The sealing ring 13 can eliminate the gap between the rotating shaft 6 and the inner ring of the bearing 5, and increase the friction with the inner ring of the bearing 5. It is easier to pull out and install when replacing the catalytic device 7. The guide shroud 14 can guide the gas when the catalytic device 7 rotates, preventing the gas from passing through the gap between the catalytic device 7 and the cylinder 1. The sealing gasket 15 can fill the gap between the cover plate 2 and the cylinder 1, improve the sealing effect, and prevent the gas from escaping. The fixing ring 16 is fitted on the surface of the cover plate 2, so that the fixing ring 16 distributes the pressure evenly on the cover plate 2, and prevents the cover plate 2 from being unevenly stressed and one end from tilting up, which affects the sealing effect. The fixing ring 16 is driven to move to the right by the screw 17 to squeeze the cover plate 2, which makes it easier to fix the cover plate 2. By rotating the screw 17, the screw 17 moves to the right side of the inner wall of the protrusion 18 under the push of the thread, and at the same time, the fixing ring 16 squeezes the cover plate 2 to fix the cover plate 2.

[0039] In summary, this gas-solid phase reactor, by setting a cover plate 2, can seal the left side of the cylinder 1 to prevent gas leakage. At the same time, it can be opened when the catalyst device 7 needs to be replaced, so that the rotating shaft 6 can be taken out to replace the catalyst device 7. The bearing 5 can support and limit the rotating shaft 6, and at the same time reduce the resistance when the rotating shaft 6 rotates, making the rotating shaft 6 rotate more smoothly. This solves the problem of existing reactors that directly drive the rotating shaft to rotate with a motor, resulting in gaps between the rotating shaft and the cylinder, which makes it easy for gas to leak through the gaps.
