[0024] The features and exemplary embodiments of various aspects of the utility model will be described in detail below. In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the utility model, rather than to limit the utility model. For those skilled in the art, the utility model can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the utility model by showing examples of the utility model.
[0025] like Figure 1 As shown, the utility model provides a catalyst dense phase filling device, which includes a barrel 1, a flow regulating mechanism 2 and a distribution mechanism 3. The barrel 1 is provided with a accommodating chamber inside, and the top and bottom of the barrel 1 are respectively provided with a feed port 11 and a discharge port connected to the accommodating chamber. The flow regulating mechanism 2 is installed at the discharge port and can adjust the outflow rate of catalyst particles per unit time at the discharge port. The distribution mechanism 3 includes a distribution trough 31 and a first driver 32. The distribution trough 31 can be circumferentially rotatably installed below the discharge port. The distribution trough 31 is connected to the discharge port so as to receive catalyst particles from the barrel 1. The distribution trough 31 is provided with a plurality of distribution holes 33 for allowing catalyst particles to fall. The first driver 32 can drive the distribution trough 31 to rotate around the axis of the barrel 1.
[0026] Specifically, catalyst particles are added to the feed port 11, and then the catalyst particles enter the containing chamber through the feed port 11, and then the catalyst particles enter the distribution trough 31 of the distribution mechanism 3 through the discharge port, so the outflow rate of catalyst particles per unit time at the discharge port is equal to the inflow rate of catalyst particles per unit time at the distribution trough 31. The first driver 32 can drive the distribution trough 31 to rotate around the axis of the barrel 1, so that the catalyst particles in the distribution trough 31 are evenly added (to be precise, added in a scattering manner) to the reactor from the distribution hole 33. Therefore, the amount of catalyst particles added per unit time in the distribution trough 31 is the amount of catalyst particles added per unit time in the catalyst dense phase filling device. Since the flow regulating mechanism 2 is installed at the discharge port, the flow regulating mechanism 2 can adjust the outflow rate of catalyst particles per unit time at the discharge port and the inflow rate of catalyst particles per unit time in the distribution trough 31, thereby adjusting the amount of catalyst particles added per unit time in the distribution trough 31, that is, adjusting the amount of catalyst particles added per unit time in the catalyst dense phase filling device. Therefore, the catalyst dense phase filling device of the utility model can adjust the dosage of catalyst particles per unit time, so as to accurately adapt to actual production needs.
[0027] For example, by adjusting the flow regulating mechanism 2, the outflow rate of catalyst particles per unit time at the discharge port increases, and the number of catalyst particles entering the distribution trough 31 per unit time increases. Accordingly, the amount of catalyst particles added per unit time in the distribution trough 31 will increase, that is, the amount of catalyst particles added per unit time in the catalyst dense phase filling device increases. For another example, by adjusting the flow regulating mechanism 2, the outflow rate of catalyst particles per unit time at the discharge port decreases, and the number of catalyst particles entering the distribution trough 31 per unit time decreases. Accordingly, the amount of catalyst particles added per unit time in the distribution trough 31 will decrease, that is, the amount of catalyst particles added per unit time in the catalyst dense phase filling device decreases. Of course, the number of distribution holes 33 is sufficient to ensure that the adjustment is achieved.
[0028] In some embodiments, the first driver 32 may include a control unit, which may be a control panel with various function keys or a control panel with various function options, etc. On-site personnel may control the operation of the first driver 32 through the control unit of the first driver 32, thereby controlling the operation of the fabric distributing mechanism 3.
[0029] In some embodiments, the flow regulating mechanism 2 can be configured in a form similar to a butterfly valve, for example, the flow regulating mechanism 2 includes a handle and a circular plate, the circular plate is located at the discharge port of the barrel 1, and a rotating shaft is provided on opposite sides of the circular plate, the two rotating shafts are rotatably connected to the barrel 1, and the handle is located outside the barrel 1 and is fixedly connected to one of the rotating shafts; when the on-site personnel rotate the handle, the handle drives the circular plate to rotate vertically, thereby changing the angle between the circular plate and the plane where the discharge port is located, that is, changing the opening of the discharge port, so as to adjust the outflow of catalyst particles per unit time from the discharge port. Of course, the flow regulating mechanism 2 can also be other structural forms, which are no longer listed in the utility model. In some embodiments, the first driver 32 can be a drive motor.
[0030] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, the flow regulating mechanism 2 includes a bottom plate 21, an adjusting plate 22 and a second driver 23. The bottom plate 21 is located at the discharge port and is sealed with the inner wall of the barrel 1. A discharge hole 211 is provided on the bottom plate 21. The discharge hole 211 is arranged between the center of the bottom plate 21 and the outer edge of the bottom plate 21; the adjusting plate 22 is arranged to be able to rotate circumferentially relative to the bottom plate 21; the second driver 23 can drive the adjusting plate 22 to rotate circumferentially so that the adjusting plate 22 can adjust the opening of the discharge port.
[0031] Specifically, the adjustment plate 22 can be a circular plate or a fan-shaped plate, etc., which is not limited by the utility model. The adjustment plate 22 and the bottom plate 21 are arranged parallel to each other, and an appropriate distance is reserved between the adjustment plate 22 and the bottom plate 21 to avoid friction between the two. The adjustment plate 22 can be rotatably connected to the center of the bottom plate 21 so that the second driver 23 can drive the adjustment plate 22 to rotate circumferentially relative to the bottom plate 21 around the center of the bottom plate 21. When the adjustment plate 22 rotates to a position away from the discharge hole 211, the discharge port remains fully open. When the adjustment plate 22 rotates to a position that shields part of the discharge hole 211, part of the discharge hole 211 is opened, and the larger the shielded part, the smaller the unit time outflow of the catalyst particles. When the adjustment plate 22 rotates to a position that shields all the discharge holes 211, the discharge hole 211 is closed. Therefore, the opening of the discharge hole 211 can be changed by driving the adjustment plate 22 to rotate, thereby adjusting the unit time flow of the catalyst particles.
[0032] In some embodiments, the second driver 23 and the adjustment plate 22 can be matched in any manner that can achieve the above-mentioned effect, and the present invention does not limit it. For example, the second driver 23 can be a cylinder or a hydraulic cylinder, and the second driver 23 can drive the adjustment plate 22 to rotate through a common connecting rod mechanism.
[0033] In some embodiments, the second driver 23 may also include a control unit, which may also be a control panel with various function buttons or a control panel with various function options, etc. On-site personnel may control the operation of the second driver 23 through the control unit of the second driver 23, thereby driving the adjustment plate 22 to adjust the opening of the discharge port.
[0034] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, the flow regulating mechanism 2 further includes an annular connecting platform 24 located at the discharge port and arranged in an annular shape, the outer periphery of the annular connecting platform 24 is sealedly connected to the inner wall of the barrel 1, and the outer periphery of the bottom plate 21 is sealedly connected to the inner periphery of the annular connecting platform 24. The inner periphery of the annular connecting platform 24 is provided with an annular slot 241, the slot 241 is recessed from the inner periphery of the annular connecting platform 24 to its outer periphery, and the slot 241 is arranged above the bottom plate 21. The slot 241 surrounds the adjustment plate 22, and the outer periphery of the adjustment plate 22 is fully movably inserted into the slot 241, and the second driver 23 drives the adjustment plate 22 to rotate through the gear transmission mechanism.
[0035] Specifically, the thickness of the annular connecting platform 24 is greater than the thickness of the bottom plate 21. The barrel 1 can be a cylinder, the annular connecting platform 24 can be a circular ring, the bottom plate 21 and the adjustment plate 22 can be circular plates, the diameter of the adjustment plate 22 is greater than the diameter of the bottom plate 21, and the axis of the bottom plate 21 coincides with the axis of the adjustment plate 22. The adjustment plate 22 can be rotatably mounted at the center of the top of the bottom plate 21. And because the adjustment plate 22 is inserted into the slot 241, a certain sealing can be maintained between the adjustment plate 22 and the annular connecting platform 24 to prevent catalyst particles from entering between the adjustment plate 22 and the bottom plate 21. Of course, appropriate gaps are reserved between the top surface of the adjustment plate 22 and the top wall of the slot 241, between the bottom surface of the adjustment plate 22 and the bottom wall of the slot 241, and between the outer peripheral wall of the adjustment plate 22 and the side wall of the slot 241, so that the adjustment plate 22 can rotate smoothly.
[0036] In some other embodiments, the slot 241 may also be disposed below the bottom plate 21 , and the adjustment plate 22 may be rotatably mounted at the center of the bottom of the bottom plate 21 .
[0037] like Figure 2 As shown, in some embodiments of the utility model, the gear transmission mechanism includes an outer ring gear 25 and a transmission gear 26, the outer ring gear 25 is arranged on the outer periphery of the adjustment plate 22, the transmission gear 26 is rotatably installed in the annular connecting platform 24, the outer ring gear 25 is meshed with the transmission gear 26, the second driver 23 can drive the transmission gear 26 to rotate circumferentially, and the second driver 23 is fixedly installed on the annular connecting platform 24.
[0038] Specifically, the inner periphery of the outer gear ring 25 is fixedly connected to the outer periphery of the adjustment plate 22, and the axis of the outer gear ring 25 coincides with the axis of the adjustment plate 22. Of course, the outer gear ring 25 can be connected to the adjustment plate 22 by means of one-piece molding or welding, etc., which is not limited by the present utility model. The second driver 23 can be a driving motor, and the transmission gear 26 is installed on the output shaft of the second driver 23. The second driver 23 can drive the transmission gear 26 to rotate, and the transmission gear 26 further drives the outer gear ring 25 to rotate, and the outer gear ring 25 drives the adjustment plate 22 to rotate. During the rotation of the adjustment plate 22, the opening of the discharge hole 211 can change, thereby adjusting the unit time flow rate of the catalyst particles.
[0039] In some embodiments of the utility model, the catalyst dense phase filling device may further include a flow sensor 242 and a controller. The controller is arranged outside the barrel 1, and the flow sensor 242 is arranged at the bottom of the annular connecting platform 24, and the flow sensor 242 is connected to the controller signal. At the same time, the first driver 32 and the second driver 23 are respectively connected to the controller signal. When the catalyst particles move to the reactor through the discharge hole 211, the flow sensor 242 can detect the catalyst particles per unit time flow at the discharge hole 211, and the flow sensor 242 can send the catalyst particles per unit time flow to the controller, and the controller stores the adjustment standard, and then the controller can send instructions to the second driver 23 according to the adjustment standard, and then control the second driver 23 to drive the adjustment plate 22 to rotate, so as to adjust the opening of the discharge hole 211. Of course, the controller may also include a control unit, which may be a control panel with various function buttons or a control panel with various function options. The on-site personnel can control the operation of the second driver 23 through the control unit of the controller, and then adjust the catalyst particles per unit time flow. Of course, the controller can also control the operation of the first driver 32.
[0040] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the bottom plate 21 is a circular plate and is provided with two fan-shaped discharge holes 211, and the two discharge holes 211 are distributed on both sides of the center of the bottom plate 21 in an axisymmetric manner; the adjustment plate 22 is a circular plate and is provided with two fan-shaped adjustment holes 221, and the two adjustment holes 221 are distributed on both sides of the center of the bottom plate 21 in an axisymmetric manner. And when one of the adjustment holes 221 is completely aligned with one of the discharge holes 211, the other adjustment hole 221 is completely aligned with the other discharge hole 211.
[0041] Specifically, the center lines of the two discharge holes 211 overlap and pass through the center of the bottom plate 21; correspondingly, the center lines of the two adjustment holes 221 overlap and pass through the center of the adjustment hole 221. And the shape and size of the discharge hole 211 and the adjustment hole 221 are exactly the same. Therefore, when the adjustment hole 221 rotates to a position aligned with the discharge hole 211, the adjustment hole 221 and the discharge hole 211 are completely overlapped in the vertical direction. When the two adjustment holes 221 are aligned with the two discharge holes 211 respectively, the opening of the two discharge holes 211 is the largest, and the unit time flow of the discharge hole 211 is the largest at this time. When the two adjustment holes 221 are partially offset from the two discharge holes 211 respectively, part of the discharge hole 211 is blocked. When the two adjustment holes 221 are completely offset from the two discharge holes 211 respectively, the discharge hole 211 is completely blocked. Therefore, during the rotation of the regulating plate 22 , the overlap between the discharge hole 211 and the regulating hole 221 may change, thereby adjusting the flow rate per unit time of the catalyst particles.
[0042] like Figure 1 and Figure 4 As shown, in some embodiments of the utility model, the material distribution mechanism 3 includes a transmission rod 27, which is rotatably disposed in the barrel 1, and the transmission rod 27 is rotatably passed through the center of the bottom plate 21 and the center of the adjustment plate 22. The axis of the transmission rod 27 coincides with the axis of the barrel 1. The top end of the transmission rod 27 extends from the feed port 11 of the barrel 1 and is connected to the first driver 32, and the first driver 32 can drive the transmission rod 27 to rotate circumferentially. The bottom end of the transmission rod 27 extends from the discharge port of the barrel 1 and is fixedly connected to the material distribution groove 31.
[0043] Specifically, the length of the transmission rod 27 is greater than the length of the barrel 1, but the diameter of the transmission rod 27 is much smaller than the diameter of the barrel 1. The top of the transmission rod 27 extends upward from the top of the barrel 1, and the top of the transmission rod 27 is connected to the first driver 32. The bottom of the transmission rod 27 extends downward from the bottom of the barrel 1, the transmission rod 27 passes through the bottom plate 21 and the adjustment plate 22, and the bottom of the transmission rod 27 is fixedly connected to the material distribution groove 31. The first driver 32 can drive the transmission rod 27 to rotate circumferentially, and the transmission rod 27 can drive the material distribution groove 31 to rotate circumferentially, that is, the material distribution groove 31 rotates around the axis of the transmission rod 27. Of course, the transmission rod 27 is rotatably passed through the bottom plate 21 and the adjustment plate 22, so that the rotation of the transmission rod 27 and the rotation of the adjustment plate 22 are independent of each other. Preferably, rolling bearings can be set between the adjustment plate 22 and the transmission rod 27 and between the bottom plate 21 and the transmission rod 27 to reduce friction. Preferably, the first driver 32 may be a driving motor, and an output shaft of the first driver 32 is connected to the top end of the transmission rod 27 .
[0044] like Figure 1As shown, in some embodiments of the present invention, the first driver 32 is located above the feed port 11 , and the first driver 32 is fixedly connected to the barrel 1 through a plurality of first connecting rods 321 that are spaced apart.

[0046] like Figure 4 As shown, in some embodiments of the utility model, the cloth mechanism 3 also includes a fixed frame 28, the fixed frame 28 includes a fixed ring 281 and a plurality of second connecting rods 282, the transmission rod 27 passes through the fixed ring 281, and the transmission rod 27 is connected to the fixed ring 281 through a bearing, and the fixed ring 281 is connected to the inner wall of the barrel 1 through the second connecting rods 282.
[0047] Specifically, all the second connecting rods 282 are evenly distributed around the fixing ring 281, and the second connecting rods 282 can fix the fixing ring 281, and the fixing ring 281 can limit the radial movement of the transmission rod 27, so that the transmission rod 27 can rotate stably in the barrel 1. In addition, a rolling bearing is provided between the transmission rod 27 and the fixing ring 281, which can ensure that the transmission rod 27 rotates smoothly.
[0048] like Figure 5 As shown, in some embodiments of the present invention, the material distribution trough 31 includes a cylindrical trough side plate and a circular trough bottom plate, the transmission rod 27 is connected to the center of the trough bottom plate, the trough bottom plate is sealed and installed at the bottom of the trough side plate, and the trough side plate is provided with a material distribution hole 33.
[0049] Specifically, the opening of the distribution trough 31 faces the discharge port and the discharge hole 211, so the catalyst particles flowing out of the discharge hole 211 can directly enter the distribution trough 31, and the catalyst particles can leave the distribution trough 31 through the distribution hole 33. The first driver 32 can drive the distribution trough 31 to rotate circumferentially through the transmission rod 27, so that the catalyst particles leaving the distribution hole 33 can be evenly scattered.
[0050] like Figure 1 As shown, in some embodiments of the utility model, the catalyst dense phase filling device further includes a support mechanism 4, which includes a vertically extending support rod 42 and an annular annular base 41, the top of the support rod 42 is fixedly connected to the outer wall of the barrel 1, the bottom of the support rod 42 is fixedly connected to the inner side of the annular base 41, the axis of the annular base 41 is consistent with the axis of the barrel 1, and the inner diameter of the annular base 41 is greater than the outer diameter of the barrel 1. The support mechanism 4 can support the barrel 1 so that the catalyst particles can be stably scattered, and the annular base 41 will not interfere with the material distribution trough 31.
