Description

Technical Field

[0001] The utility model relates to the technical field of rotary valves, in particular to an activated carbon desulfurization conveying rotary valve. Background Art

[0002] Activated carbon desulfurization conveying rotary valve is usually used in activated carbon desulfurization equipment to control the conveying and flow of activated carbon. This valve usually adopts a rotary structure to control the on-off or flow rate of the fluid by rotating the valve core or valve plate. It is usually used in pipeline systems for conveying particles, powders, granules or particles, which can effectively control the flow direction and speed of materials and ensure the stability and efficiency of the production process.

[0003] For example, the patent number of "CN110155630A" is an activated carbon desulfurization and denitrification conveying rotary valve, which is provided with a valve body, a cylindrical inner cavity is provided in the valve body, a feed port is provided on the valve body, a right end cover and a left end cover are provided on both sides of the valve body, the valve body is sealed and connected with the right end cover and the left end cover, the right end cover and the left end cover are penetrated and rotated with a rotor, the rotor includes a main shaft and a valve disc, the main shaft penetrates the right end cover and the left end cover, the main shaft is rotatably connected with the right end cover and the left end cover, the valve disc is fixed on the main shaft, the valve disc is located in the cylindrical inner cavity, the valve disc fixed on the main shaft is a curved surface shape, and the curved surface shape of the valve disc can form a coated state of the conveyed activated carbon when rotating, which solves the technical problem that the activated carbon particles in the existing activated carbon dry desulfurization and denitrification device will be damaged during the transfer process of the circulating transportation system due to falling, wear and shearing of the rotating equipment. The present invention can be widely used in the field of activated carbon desulfurization and denitrification transportation.

[0004] However, in the prior art, long-term transportation of activated carbon may have some impact on the interior of the rotary valve. Since activated carbon has certain granularity and adsorption capacity, long-term transportation may cause activated carbon particles to accumulate inside the rotary valve. This accumulation may cause a layer of activated carbon deposits to form on the inner wall of the valve body, which will affect the normal operation of the valve to a certain extent. Therefore, it is necessary to clean the inside of the rotary valve regularly. The use of the rotary valve requires good sealing to avoid leakage of activated carbon. At the same time, the rotating connection parts inside the rotary valve also require good sealing functions. Otherwise, more activated carbon will enter the gap in the rotating position, which will greatly increase the resistance of the motor drive, thereby reducing the service life of the equipment. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that long-term transportation may cause activated carbon particles to accumulate inside the rotary valve, and such accumulation may cause a layer of activated carbon deposits to form on the inner wall of the valve body, thus affecting the normal operation of the valve to a certain extent.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an activated carbon desulfurization conveying rotary valve, comprising a valve body, a rotating core and a motor, the rotating core is sealingly and rotatably arranged in the valve body, the motor is arranged outside one end of the valve body, the rotating core is driven to rotate by the motor, a feed port and a discharge port are respectively provided at the center positions above and below the valve body, a first sealing plate and a second sealing plate are respectively provided inside the valve body at both ends of the rotating core, the two ends of the rotating core are respectively connected to the first sealing plate and the second sealing plate in a sealing and rotatable manner, the output end of the motor passes through one end of the valve body and the first sealing plate and is linked to the center position of the end face of the rotating core, the end of the valve body away from the motor is detachably provided with an end cover with a thread, and the inner side of the end cover is assembled and connected with the center position of the second sealing plate through a resist.

As the rotating blades rotate, the activated carbon can be driven to the discharge port below and the conveying effect can be achieved.

[0008] As a preferred embodiment, the two ends of the rotating blade are fixedly assembled with the two end plates, the rotating blade is an arc-shaped plate structure, and the side of the rotating blade away from the central axis is flush with the edge of the end plate. By fixedly assembling the edge and end face of the rotating blade with the central axis and the end plate respectively, leakage of material during the rotating blade rotation and conveying process can be avoided, which makes it difficult to stop the flow when stopping transportation.

[0009] As a preferred embodiment, the edge positions of the first sealing plate and the second sealing plate have the same structure and are symmetrically arranged. A groove is provided at the center position of the side of the first sealing plate in contact with the rotating core, and a convex plate that fits the groove is provided on the side of the end plate away from the central axis. The convex plate and the groove are inclined at the edge position where they are connected, and a first sealing ring is provided at the edge position of the groove. The convex plate is sealed and engaged with the first sealing ring at the edge position for rotation. The rotation stability between the first sealing plate and the end plate is achieved through the engagement and installation of the groove and the convex plate. Even if powder enters the gap, the powder will overflow from the inclined slope when the convex plate rotates to the bottom, and it is difficult for the powder to stay between the groove and the convex plate for a long time, thereby providing a guarantee for the sealing during rotation. The first sealing ring that is provided can effectively ensure the sealing of the first sealing plate and the end plate during rotation, and prevent powder from entering from the gap connecting the groove and the convex plate, thereby ensuring the sealing.

[0010] As a preferred embodiment, a snap ring is provided at the edge of the convex plate located on the inner side of the first sealing ring, and a groove which is snap-fitted with the snap ring is provided at the edge of the first sealing plate. Through the snap-fitting between the snap ring and the groove, even if some activated carbon powder passes through the first sealing ring, it will be blocked by the snap ring and will not enter the output end of the motor.

[0011] As a preferred embodiment, a slide groove is provided above the inner wall of the valve body near the end cover, and the first sealing plate is rotatably engaged with the central axis and is slidably engaged with the slide groove through a slider above.

[0012] As a preferred embodiment, a sealing plug is provided on the inner side of the end cover, one end of the resist is assembled and connected to the center position of the sealing plug, the other end of the resist is rotatably assembled and connected to the first sealing plate, the sealing plug is threadedly rotatably connected to the inner wall of the valve body, the valve body is provided with a flange on the outer side of one end of the sealing plug, the end cover and the flange are assembled and connected by bolts. When installing the end cover, the first sealing plate and the resist are first inserted into the valve body, and then the end cover is rotated to drive the sealing plug to rotate, thereby realizing a threaded connection. When rotated to the bottom, the holes on the end cover and the flange are connected, and then they can be fixed by bolts, which effectively prevents thread slippage when the thread rotates.

[0013] As a preferred embodiment, the abutment includes a telescopic shaft and a spring, and the spring is sleeved on the outside of the telescopic shaft. The two ends of the telescopic shaft and the spring are respectively assembled and connected with the sealing plug and the first sealing plate. By setting the abutment, the thrust between the first sealing plate and the rotating core can be increased to a certain extent, thereby increasing the sealing performance.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. The utility model is disassembled by threading the end cover and the end face of the valve body. Since the end cover is assembled and connected with the second sealing plate through a stopper, the second sealing plate can be taken out in conjunction with the end cover when it is taken out, and then the rotating core can be directly taken out. During the removal process, the rotating core is separated from the motor output end. At this time, only the first sealing plate and the motor set outside are left on the valve body. The staff can directly clean the inside of the valve body and the first sealing plate, and clean the disassembled rotating core, the second sealing plate and the end cover. After cleaning, they can be reinstalled. The operation is simple and convenient to use.

[0016] 2. The utility model can effectively ensure the end face sealing of the rotating core during the rotation of the rotating core by the sealing rotation cooperation between the first sealing plate and the second sealing plate. At the same time, after the end cover is installed, the resistance member pushes the second sealing plate to move toward the rotating core, so that the connection between the first sealing plate, the rotating core and the first sealing plate is more secure, and the possibility of a large gap at the rotating position after long-term use is reduced, thereby ensuring the sealing of the connection position and avoiding leakage.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-7The utility model provides a technical solution: an activated carbon desulfurization conveying rotary valve, comprising a valve body 1, a rotary core 2 and a motor 3. The rotary core 2 is sealed and rotatably arranged in the valve body 1, and the motor 3 is arranged outside one end of the valve body 1. The rotary core 2 is driven to rotate by the motor 3. A feed port 4 and a discharge port 5 are respectively arranged at the center positions above and below the valve body 1. A first sealing plate 6 and a second sealing plate 7 are respectively arranged inside the valve body 1 at both ends of the rotary core 2. Both ends of the rotary core 2 are sealed and rotatably connected with the first sealing plate 6 and the second sealing plate 7 respectively. The output end of the motor 3 passes through one end of the valve body 1 and the first sealing plate 6 and is linked to the center position of the end face of the rotary core 2. A threaded end cover 8 is detachably provided at one end of the valve body 1 away from the motor 3. The inner side of the end cover 8 is assembled and connected with the center position of the second sealing plate 7 by a resisting member 9. When disassembling, the staff can disassemble by threading the end cover 8 and the end face of the valve body 1. Since the end cover 8 is assembled and connected with the second sealing plate 7 by a resisting member 9, When the end cover 8 is taken out, the second sealing plate 7 can be taken out in conjunction, and then the rotating core 2 can be directly taken out. During the removal process, the rotating core 2 is separated from the output end of the motor 3. At this time, only the first sealing plate 6 and the motor 3 set outside are left on the valve body 1. The staff can directly clean the inside of the valve body 1 and the first sealing plate 6, and clean the disassembled rotating core 2, the second sealing plate 7 and the end cover 8. After the cleaning is completed, they can be reinstalled. The operation is simple and convenient to use. At the same time, the sealing rotation between the first sealing plate 6 and the second sealing plate 7 on the rotating core 2 can effectively ensure the end face sealing of the rotating core 2 during the rotation of the rotating core 2. At the same time, after the end cover 8 is installed, the push piece 9 pushes the second sealing plate 7 to move toward the rotating core 2, so that the connection between the first sealing plate 6, the rotating core 2 and the first sealing plate 6 is more firmly connected, and the possibility of a large gap at the rotating position after long-term use is reduced, thereby ensuring the sealing of the connection position and avoiding leakage.

[0028] like Figure 1-7 As shown, the rotating core 2 includes an end plate 10, a central axis 11 and rotating blades 12. Two end plates 10 are provided and are symmetrically arranged at both ends of the central axis 11. A plurality of rotating blades 12 are provided and are assembled and connected with the central axis 11. A sleeve 13 is provided at the center position of one side of the end plate 10 close to the motor 3. The sleeve 13 is clamped and sleeved on the outside of the output shaft of the motor 3. The outside of the sleeve 13 penetrates and is rotatably arranged at the center position of the first sealing plate 6, wherein the motor 3 is electrically connected to an external power supply, and then the sleeve 13 is driven to rotate by driving the motor 3, thereby driving the end plate 10 to drive the central axis 11 and the rotating blades 12 to rotate synchronously, and the activated carbon discharged from the feed port 4 falls between the rotating blades 12. As the rotating blades 12 rotate, the activated carbon can be driven to the discharge port 5 below and the conveying effect can be achieved.

[0029] like Figure 1-7As shown, both ends of the rotating blade 12 are fixedly assembled and connected to the two end plates 10. The rotating blade 12 is an arc-shaped plate structure. The side of the rotating blade 12 away from the central axis 11 is flush with the edge of the end plate 10. By fixedly assembling and connecting the edge and end face of the rotating blade 12 to the central axis 11 and the end plate 10 respectively, leakage of material during the rotation and transportation of the rotating blade 12 can be avoided, which would make it difficult to stop the flow when stopping the transportation.

[0030] like Figure 1-7 As shown, the edge positions of the first sealing plate 6 and the second sealing plate 7 have the same structure and are symmetrically arranged. A groove 14 is provided at the center position of the side of the first sealing plate 6 that contacts the rotating core 2. A convex plate 15 that fits the groove 14 is provided on the side of the end plate 10 away from the central axis 11. The convex plate 15 is inclined at the edge position where the groove 14 is connected. A first sealing ring 16 is provided at the edge position of the groove 14. The edge position of the convex plate 15 is sealed and engaged with the first sealing ring 16 for rotation. The rotation stability between the first sealing plate 6 and the end plate 10 is achieved through the engagement and installation of the groove 14 and the convex plate 15. At the same time, even if powder enters the gap, the powder will overflow from the inclined slope position when the convex plate 15 rotates to the bottom, and it is difficult for the powder to stay between the groove 14 and the convex plate 15 for a long time, thereby providing a guarantee for the sealing during rotation. The first sealing ring 16 is provided to effectively ensure the sealing of the first sealing plate 6 and the end plate 10 during rotation, and prevent the powder from entering from the gap connecting the groove 14 and the convex plate 15, thereby ensuring the sealing.

[0031] like Figure 1-7 As shown, a snap ring 17 is provided at the edge of the convex plate 15 located on the inner side of the first sealing ring 16, and a groove 18 that fits with the snap ring 17 is provided at the edge of the first sealing plate 6. Through the fit between the snap ring 17 and the groove 18, even if some activated carbon powder passes through the first sealing ring 16, it will be blocked by the snap ring 17 and will not enter the output end of the motor 3.

[0032] like Figure 1-7 As shown, a slide groove 19 is provided on the upper part of the inner wall of the valve body 1 near the end cover 8, the first sealing plate 6 is rotatably engaged with the central axis 11 and the upper part is slidably engaged with the slide groove 19 through a slider 20. The sliding engagement of the slider 20 and the slide groove 19 effectively ensures the stability of the installation of the first sealing plate 6 relative to the valve body 1, avoiding the first sealing plate 6 from rotating when the rotating core 2 rotates.

[0033] like Figure 1-7As shown, a sealing plug 21 is provided on the inner side of the end cover 8, one end of the resisting member 9 is assembled and connected with the center position of the sealing plug 21, and the other end of the resisting member 9 is rotatably assembled and connected with the first sealing plate 6, and the sealing plug 21 is threadedly rotatably connected with the inner wall of the valve body 1. The valve body 1 is provided with a flange 22 on the outer side of one end of the sealing plug 21, and the end cover 8 and the flange 22 are assembled and connected by bolts 23. When installing the end cover 8, the first sealing plate 6 and the resisting member 9 can be inserted into the valve body 1 first, and then the end cover 8 can be rotated to drive the sealing plug 21 to rotate, so as to realize the threaded connection. When it is rotated to the bottom, the holes on the end cover 8 and the flange 22 are connected, and then it can be fixed by bolts 23, which effectively prevents the thread from slipping when rotating.

[0034] like Figure 1-7 As shown, the resist 9 includes a telescopic shaft 24 and a spring 25. The spring is sleeved on the outside of the telescopic shaft 24. The two ends of the telescopic shaft 24 and the spring 25 are respectively assembled and connected with the sealing plug 21 and the first sealing plate 6. By setting the resist 9, the thrust between the first sealing plate 6 and the rotating core 2 can be increased to a certain extent, thereby increasing the sealing performance.

[0035] Working principle: When disassembling, the staff can disassemble by threading the end cover 8 and the end face of the valve body 1. Since the end cover 8 is assembled and connected with the second sealing plate 7 through the stopper 9, the second sealing plate 7 can be taken out after the end cover 8 is taken out, and then the rotating core 2 can be directly taken out. During the removal process, the rotating core 2 is separated from the output end of the motor 3. At this time, only the first sealing plate 6 and the motor 3 set outside are left on the valve body 1. The staff can directly clean the inside of the valve body 1 and the first sealing plate 6, and clean the disassembled rotating core 2, the second sealing plate 7 and the end cover 8. After cleaning, it can be reinstalled. The operation is simple and easy to use. At the same time, the sealing rotation between the first sealing plate 6 and the second sealing plate 7 on the rotating core 2 can effectively ensure the end face sealing of the rotating core 2 during rotation. At the same time, after the end cover 8 is installed, the resistance member 9 pushes the second sealing plate 7 to move toward the rotating core 2, so that the connection between the first sealing plate 6, the rotating core 2 and the first sealing plate 6 is more secure, and the possibility of a large gap at the rotating position after long-term use is reduced, thereby ensuring the sealing of the connection position and avoiding leakage.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
