Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a drying device for catalyst production. Background Art

[0002] In the catalyst production process, drying is a crucial link. The main purpose of drying is to remove moisture and other volatile substances in the catalyst to meet the specified water content requirements and ensure the performance, stability and service life of the catalyst. The drying process not only affects the physical properties of the catalyst, such as specific surface area, pore structure, etc., but also has an important impact on its chemical properties.

[0003] Common catalyst drying methods generally use hot air drying. Hot air drying uses hot air as a drying medium to transfer heat to the catalyst through convection heat exchange, so that the moisture evaporates and is taken away by the air. However, during the drying process, catalyst powder particles may agglomerate. The moisture on the outer surface of the agglomerate evaporates, but the moisture inside the agglomerated catalyst is not easy to evaporate, resulting in poor catalyst drying effect.

[0004] Therefore, the hot air drying method causes the catalyst to agglomerate. Therefore, a ball mill is used to break up the agglomerated catalyst. However, the hot air in the ball mill generally rises automatically, causing too much high temperature to accumulate in the air, resulting in the hot air being unable to increase the contact time with the catalyst. To address this type of problem, the only way to achieve the drying effect is to increase more energy and improve the problems inside the ball mill. For this reason, the present invention provides a drying device for catalyst production. Summary of the invention

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] Example: Refer to Figure 1 , Figure 2 and Figure 7 The present invention provides a technical solution: a drying device for catalyst production, comprising: a grinding mechanism, the grinding mechanism comprising two grinding cylinders 1, used to cooperate with an annular plate 11 to accommodate multiple grinding balls, the inner wall of the grinding cylinder 1 is conical, the annular plate 11 can splice the ends with the largest radius of the two grinding cylinders 1 to collect materials on the inner walls of the two grinding cylinders 1 or support the grinding mechanism, and the two grinding cylinders 1 and the annular plate 11 form an airtight constant temperature gas environment;

[0038] The exhaust mechanism includes two rotating shafts 40 and fan blades 46 that are self-rotating in the annular plate 11. The fan blades 46 are arranged at the bottom of the rotating shaft 40, and the rotating shaft 40 and the fan blades 46 are located at the highest point of the annular plate 11. The annular plate 11 has two exhaust cavities. The rotating shaft 40 is used to drive the fan blades 46 to rotate to control the discharge of moisture from the exhaust cavity.

[0039] like Figures 2 to 6As shown, an arc plate 14 is fixedly installed on the inner wall of the annular plate 11, and a feed pipe 10 is connected to the highest point of the annular plate 11. The bottom end of the feed pipe 10 passes through and is fixedly installed with a heating shell 23. A conical base 20 is fixedly installed on the bottom end of the feed pipe 10, and the conical base 20 is located on the inner wall of the heating shell 23. The outer wall of the lowest point of the conical base 20 is connected to two delivery pipes 21, and the delivery pipes 21 pass through and are fixedly installed at the lowest point of the heating shell 23.

[0040] When the staff needs to dry the catalyst, first the catalyst is passed from the inner wall of the feed pipe 10 through the conical base 20 and the feed pipe 21 into the grinding cylinder 1, and then Figure 2 As shown, the support tube 22 on the right side is connected to an external motor, and the motor drives the support tube 22 to drive the two grinding cylinders 1 to rotate. During the rotation of the two grinding cylinders 1 at both ends of the annular plate 11, as shown in the attached Figure 2 As shown, the grinding mechanism is formed by a space composed of a heating shell 23, two grinding cylinders 1 and an annular plate 11, and the adjacent limiting plates 5 contain the same number of grinding balls, and the horizontal height of the grinding balls does not exceed the horizontal height of the support tube 22. During the rotation of the grinding cylinder 1, multiple grinding balls rotate on the inner wall of the grinding cylinder 1 and the annular plate 11, and the grinding balls are driven by the limiting plates 5 to the highest point of the grinding cylinder 1 and fall to the lowest point of the grinding cylinder 1, so that the catalyst can be crushed to avoid agglomeration. The material transported by the feeding pipe 21 will be fed from the end of the two grinding cylinders 1 that is farthest away, thereby increasing the contact coverage area between the material and the grinding balls.

[0041] When dehumidification is required, hot air is discharged from the heating housing 23 through the air outlet 31, and the hot air fills the inner walls of the two grinding cylinders 1 and the annular plate 11, and evaporates the moisture contained in the catalyst particles. Then, the two grinding cylinders 1 rotate to drive the exhaust mechanism to discharge the water vapor on the inner wall of the grinding mechanism to the outside, so as to avoid the occurrence of water vapor residue on the inner wall of the grinding mechanism. At the same time, during the drying process, the inner wall of the feed pipe 10 needs to be blocked in advance with a plug;

[0042] When it is necessary to take out the material, the staff only needs to take out the dried catalyst from the discharging piece 18 .

[0043] like Figure 2 and Figure 4As shown, a support rod 12 is fixedly installed on the outer wall of the annular plate 11, a base 13 is fixedly installed on the bottom of the support rod 12, a limiting rod 17 is fixedly installed on the top of the base 13, a rotatable threaded rod 15 is arranged on the top of the base 13, the threaded rod 15 and the limiting rod 17 are in the same plane, a blocking piece 16 is threadedly connected to the threaded rod 15, the blocking piece 16 is composed of a transverse rod and a blocking rod, and the top of the blocking rod is inclined, the outer wall of the limiting rod 17 passes through and is slidably connected to one side of the transverse rod, and a discharge piece 18 is connected to the lowest point of the annular plate 11, the discharge piece 18 is composed of an inclined tube and a discharge pipe, and the inner wall of the discharge pipe is airtightly slidably connected to the outer wall of the blocking rod.

[0044] When the drying work is completed, the staff first manually rotates the threaded rod 15. Due to the restriction of the limit rod 17, the blocking rod in the blocking piece 16 moves downward in the discharge pipe in the discharge piece 18 until the transverse rod touches the top of the base 13. At the same time, the inclination of the top of the blocking rod is in the same plane as the inclined tube, avoiding residual catalyst from remaining on the inner wall of the discharge piece 18. The inclined tube can make the material removal work more convenient and enable the use of storage devices of different volumes for material collection.

[0045] like Figure 1 , Figure 3 and Figure 5 As shown, an annular groove 28 is provided on the opposite side of the two grinding cylinders 1, and the inner wall of the annular groove 28 is airtightly slidably connected to the outer wall of the annular plate 11, and a support tube 22 is fixedly installed on the inner wall of one end of the grinding cylinder 1, and the inner walls of the two support tubes 22 are respectively solid and hollow, and the opposite ends of the two support tubes 22 are rotatably connected to one end of the heating shell 23, and the two ends of the heating shell 23 are provided with air outlet holes 31, and a fixing ring 24 is fixedly installed on the inner wall of the heating shell 23, and the fixing ring 24 and the annular plate 11 are in the same plane, and an asbestos rod 25 is fixedly installed on the inner wall of the fixing ring 24, and the other end of the asbestos rod 25 is located at the center of the fixing ring 24, and the other end of the asbestos rod 25 is fixedly installed There is a heating tube 26, and power supply components 27 are fixedly installed at both ends of the heating tube 26. One end of the power cord of the power supply component 27 can pass through the inner wall of the hollow support tube 22. The separated ends of the two support tubes 22 are rotatably connected with a support frame 3. A base 2 30 is fixedly installed at the bottom of the support frame 3. The support frame 3 can slide linearly on the outer wall of the support tube 22 and can contact one end of the grinding cylinder 1. A plurality of limit plates 5 are installed in a circular array on the inner wall of the grinding cylinder 1. A filter ring 50 is fixedly installed on the inner wall of the grinding cylinder 1. The inclination angles of the two ends of the heating shell 23 are the same as the inclination angles of the inner walls of the two grinding cylinders 1. The outer wall of the heating shell 23 and the number of grinding balls at different levels between the two grinding cylinders 1 are the same.

[0046] When it is necessary to disassemble the grinding mechanism, the staff can first move the two support frames 3 apart to allow the support tube 22 to detach from the inner wall of the support frame 3, and then move the two grinding cylinders 1 apart to detach from the outer wall of the annular plate 11. Finally, the internal part of the device can be maintained or cleaned. When it is necessary to dry the catalyst, in order to prevent the two grinding cylinders 1 from detaching from the outer wall of the annular plate 11, the two support frames 3 can be moved linearly toward each other and then tightly contacted with one end of the grinding cylinder 1 to prevent the two grinding cylinders 1 from detaching from the outer wall of the annular plate 11. At the same time, in order to prevent the grinding balls from entering the inner wall of the annular plate 11 and not rotating with the rotation of the grinding cylinder 1, the material can enter the inner wall of the annular plate 11 through the filter ring 50, and the grinding balls cannot reach the inner wall of the annular plate 11.

[0047] When it is necessary to provide a heat source to the heating housing 23, there are two ways;

[0048] 1. As attached Figure 2 As shown, the staff can connect the power source through the power supply unit 27, and the line is connected to the power supply unit 27 through the support tube 22 running through the left side, and then the other end of the line is connected to the external power supply, so that the heating tube 26 starts to heat up, and the hot air in the heating shell 23 is discharged from the air outlet 31. At the same time, in addition to the line, other fillers can be placed in the inner wall of the left support tube 22 to prevent the hot air in the heating shell 23 from leaking out;

[0049] 2. As attached Figure 3 As shown, the staff passes hot water into the inner wall of the heating shell 23 through the left support tube 22, and the level of the hot water is not higher than the level of the left support tube 22. Then, the inner wall of the left support tube 22 is blocked by a filler, and then the left support tube 22 and the right support tube 22 are driven to rotate by two external motors respectively. Then, the hot air generated by the hot water fills the inner wall of the grinding cylinder 1 from the inner wall of the air outlet 31 to dry the catalyst. At the same time, the catalyst drying effect can be improved by increasing the temperature of the heating shell 23.

[0050] like Figure 1 and Figures 5 to 12As shown, a gear groove 29 is provided on the opposite side of the two grinding cylinders 1, and a gear 4 is meshed in the gear groove 29. The bottom of the gear 4 is fixedly mounted on the top of the rotating shaft 40. The rotating shaft 40 is rotatably mounted on the inner wall of the exhaust cavity. The rotating shaft 40 is located on the inner wall of the annular plate 11 and has an annular groove. A vent plate 41 is fixedly mounted on the inner wall of the exhaust cavity. The inner wall of the vent plate 41 is rotatably connected to the outer wall of the rotating shaft 40. A cleaning brush 51 is fixedly mounted on the outer wall of the rotating shaft 40. A rotatable wind-expelling member 42 is provided on the outer wall of the annular groove. A crescent-shaped telescopic rod 44 is fixedly mounted on the inner wall of the annular groove. The inner wall of the crescent-shaped telescopic rod 44 has hydrogen. A clamping piece 45 is fixedly mounted on the other end of the crescent-shaped telescopic rod 44. A circular base 47 is fixedly installed at the bottom of the groove, a limiting ring 48 is fixedly installed on the top of the circular base 47, and the bottom of the circular base 47 is fixedly installed on the top of the fan blade 46. The wind-repelling member 42 consists of a circular ring and four fan plates. An annular limiting groove 49 is provided at the bottom of the circular ring. The inner wall of the annular limiting groove 49 is slidably connected to the outer wall of the limiting ring 48. A limiting groove 43 is provided on the inner wall of the circular ring. The snap-in piece 45 can be snapped onto the inner wall of the limiting groove 43. Four fixed rods 32 are fixedly installed on the inner wall of the annular plate 11. The inner walls of the two fixed rods 32 are rotatably connected with the optical axis 33. The optical axis 33 is located between the two fixed rods 32. A blocking piece 34 is fixedly installed on the outer wall of the rod body. The blocking piece 34 has a right-angle groove.

[0051] When exhaust is required, as shown in the attached Figure 2 and attached Figure 7 As shown, during the rotation of the grinding cylinder 1, the gear groove 29 drives the two gears 4 to rotate, that is, the gear 4 drives the shaft 40 and the fan blade 46 to rotate. When the fan blade 46 rotates clockwise, the wind direction is toward the feed pipe 21, which prevents the hot air from rising naturally and reduces the contact time with the catalyst. At the same time, during the clockwise rotation of the shaft 40, as shown in the attached figure Fig.10 As shown, the inner wall of the crescent-shaped telescopic rod 44 has hydrogen, so the crescent-shaped telescopic rod 44 will naturally extend in length, and the rotating shaft 40 provides centrifugal force to the crescent-shaped telescopic rod 44 during rotation, so that the clamping piece 45 can be better clamped on the inner wall of the limiting groove 43, that is, the wind driving member 42 is driven to rotate clockwise, and the exhaust mechanism can provide downward and surrounding wind force in the annular plate 11, thereby driving more hot air downward to increase the contact time with the catalyst;

[0052] When exhaust is needed, the staff only needs to operate two external motors to drive the two support tubes 22 to start reverse rotation, that is, the rotating shaft 40 rotates counterclockwise, and the fan blades 46 rotate counterclockwise to produce downward suction work. At the same time, in order to avoid the rotation of the wind driving member 42 to hinder the exhaust work of the fan blades 46, as shown in the attached Figure 8As shown, the wind-repelling member 42 can overturn the barrier sheet 34 by rotating clockwise. If the wind-repelling member 42 rotates counterclockwise, the barrier sheet 34 has a right-angle groove, so the wind-repelling member 42 cannot overturn the barrier sheet 34. Finally, the hot air carrying water vapor is discharged to the outside from the ventilation plate 41.

[0053] It is explained that the ventilation plate 41 can be penetrated by air but catalyst dust cannot penetrate it. At the same time, when the shaft 40 rotates, in order to prevent dust from blocking the air holes of the ventilation plate 41 during the exhaust process, it can be cleaned by a cleaning brush 51. In order to prevent the inside of the device from being in a negative pressure state during the exhaust process, the staff can open the inner wall of the feed pipe 10. During the exhaust process, when the inside of the device needs to be filled with air pressure, the inner wall of the feed pipe 10 automatically absorbs external air, and when passing through the high-temperature environment of the inner wall of the heating shell 23, it is converted into high-temperature air, and finally enters the inner wall of the grinding cylinder 1 through the air outlet 31, so that the internal air pressure of the device is stable.

[0054] Working principle: When the staff needs to dry the catalyst, first put the catalyst from the inner wall of the feed pipe 10 through the conical base 20 and the feed pipe 21 into the grinding cylinder 1, and then Figure 2 As shown, the support tube 22 on the right side is connected to an external motor, and the motor drives the support tube 22 to drive the two grinding cylinders 1 to rotate. During the rotation of the two grinding cylinders 1 at both ends of the annular plate 11, as shown in the attached Figure 2 As shown, the grinding mechanism is formed by a space composed of a heating shell 23, two grinding cylinders 1 and an annular plate 11, and contains a plurality of grinding balls, and the level of the accumulation of the grinding balls does not exceed the level of the support tube 22. During the rotation of the grinding cylinder 1, the plurality of grinding balls rotate on the inner wall of the grinding cylinder 1 and the annular plate 11, and the catalyst is crushed to avoid agglomeration.

[0055] When it is necessary to provide a heat source in the heating housing 23, as shown in the attached Figure 2 As shown, the staff can connect the power source through the power supply unit 27, and the line is connected to the power supply unit 27 through the support tube 22 running through the left side, and then the other end of the line is connected to the external power supply, so that the heating tube 26 starts to heat up, and the hot air in the heating shell 23 is discharged from the air outlet 31. At the same time, in addition to the line, other fillers can be placed in the inner wall of the left support tube 22 to prevent the hot air in the heating shell 23 from leaking out;

[0056] When exhaust is required, as shown in the attached Figure 2 and attached Figure 7As shown, during the rotation of the grinding cylinder 1, the gear groove 29 drives the two gears 4 to rotate, that is, the gear 4 drives the shaft 40 and the fan blade 46 to rotate. When the fan blade 46 rotates clockwise, the wind direction is toward the feed pipe 21, which prevents the hot air from rising naturally and reduces the contact time with the catalyst. At the same time, during the clockwise rotation of the shaft 40, as shown in the attached figure Fig.10 As shown, the inner wall of the crescent-shaped telescopic rod 44 has hydrogen, so the crescent-shaped telescopic rod 44 will naturally extend in length, and the rotating shaft 40 provides centrifugal force to the crescent-shaped telescopic rod 44 during rotation, so that the clamping piece 45 can be better clamped on the inner wall of the limiting groove 43, that is, the wind driving member 42 is driven to rotate clockwise, and the exhaust mechanism can provide downward and surrounding wind force in the annular plate 11, thereby driving more hot air downward to increase the contact time with the catalyst;

[0057] When exhaust is needed, the staff only needs to operate two external motors to drive the two support tubes 22 to start reverse rotation, that is, the rotating shaft 40 rotates counterclockwise, and the fan blades 46 rotate counterclockwise to produce downward suction work. At the same time, in order to avoid the rotation of the wind driving member 42 to hinder the exhaust work of the fan blades 46, as shown in the attached Figure 8 As shown, the wind-repelling member 42 can overturn the barrier sheet 34 by rotating clockwise. If the wind-repelling member 42 rotates counterclockwise, the barrier sheet 34 has a right-angle groove, so the wind-repelling member 42 cannot overturn the barrier sheet 34. Finally, the hot air carrying water vapor is discharged to the outside from the ventilation plate 41.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
