Description

Technical Field

[0001] The present invention relates to the technical field of chemical engineering, and specifically to a multi-tube feeding structure for a chemical reactor. Background Art

[0002] A chemical reactor is the core equipment for carrying out various chemical reactions in the chemical industry. It usually involves the chemical reaction process of different materials, that is, various materials are added into it through the feed pipes of the reactor and physically stirred, and finally chemical reactions occur between various materials.

[0003] During the feeding process, especially for the feeding process of multiple granular materials, currently, usually multiple external feeding pipes are simultaneously docked with the feed pipe of the reactor, and the corresponding materials are transported to the reactor through the feeding pipes and the feed pipe by a feeding pump. The feeding process of all materials is completed by using the same feed pipe in a sequential feeding manner, and the feeding amount of the materials is controlled by controlling the feeding time of the feeding pump.

[0004] For the above-mentioned feeding process of multiple materials, there are the following problems: During the process of transporting and feeding materials of different particle diameters through a feed pipe of the same diameter, no targeted limitation is imposed on the granular materials of different particle diameters. Therefore, when feeding through a feed pipe of the same diameter, the actual feeding volumes of different materials vary greatly. Specifically, when feeding in the same cross-sectional area of the pipeline, the voids between small-particle materials are small, and the voids between large-particle materials are large. That is, in a unit volume of the pipeline, the actual occupied volume of small-particle materials is greater than that of large-particle materials. Therefore, based on the existing feeding method, by controlling the feeding time of the feeding pump to control the feeding amount, it is easy to cause the actual feeding volume of small-particle materials to be excessive, affecting the subsequent mixing uniformity of multiple materials and the overall chemical reaction process. Summary of the Invention

[0005] Based on this, it is necessary to provide a multi-tube feeding structure for a chemical reactor, aiming to solve the problems of the above-mentioned existing technology.

[0006] The present application provides a multi-tube feeding structure for a chemical reactor, which is arranged on the reactor and docked with the feed pipe of the reactor. It includes: a mounting plate, a docking part for locking the mounting plate is arranged between the mounting plate and the reactor. A rotating shaft with an axis extending from left to right is rotatably arranged on the mounting plate, and a docking plate is movably sleeved on the rotating shaft. A feeding mechanism is jointly arranged on the docking plate and the mounting plate.

[0007] The feeding mechanism includes a feeding port. A plurality of circumferentially distributed feeding ports are opened on the docking plate, and a plurality of circumferentially distributed through-holes are penetrated through the mounting plate. The uppermost through-hole is docked with the feed pipe, and a material control part for controlling the feeding uniformity of the materials is arranged in all the feeding ports.

[0008] The material control part includes a material control plate. A material control plate is arranged in the feed inlet. Feed holes are formed in the material control plate. The diameters of the feed holes on different material control plates are different, and the number of feed holes with a larger diameter is smaller.

[0009] A docking unit for guiding the docking of the feed inlet and the uppermost through hole is arranged on the docking plate. The docking unit includes a cleaning group. When one of the feed inlets is docked with the uppermost through hole, the cleaning group cleans the material control plates in the remaining feed inlets.

[0010] According to a preferred embodiment, the docking part includes a docking frame. A docking frame for locking the flange on the feed pipe and the mounting plate is installed on the right end face of the mounting plate. The docking process between the uppermost through hole on the mounting plate and the feed pipe is completed by installing the docking frame.

[0011] According to a preferred embodiment, an annular frame is fixedly arranged on the left end face of the mounting plate. The inner arc surface of the annular frame is in close contact with the docking plate. Guide sleeves corresponding to the material control plates one by one are arranged on the right end face of the docking plate. In order to guide the guide sleeves to be inserted into the through holes, the left inner wall of the through holes is chamfered. The docking plate is sleeved on the rotating shaft in a left-right sliding manner.

[0012] According to a preferred embodiment, a fitting plate is sleeved on the rotating shaft in a left-right sliding manner. The guide sleeve slides through the fitting plate. A compression spring sleeved on the rotating shaft is fixedly arranged between the fitting plate and the docking plate. A pressing sleeve is fixedly arranged on the right end face of the docking plate. The rotating shaft and the compression spring penetrate through the pressing sleeve.

[0013] According to a preferred embodiment, rubber rings corresponding to the guide sleeves one by one are fixedly arranged on the right end face of the fitting plate. When the fitting plate presses the mounting plate, the sealing effect is enhanced by tightly attaching to the chamfer of the through hole through the rubber rings.

[0014] According to a preferred embodiment, the material control part further includes L-shaped grooves. Groove groups corresponding to the feed inlets one by one are formed on the right end face of the docking plate. The groove groups include a plurality of L-shaped grooves evenly distributed in the circumferential direction. Mounting blocks are fixedly arranged on the circumferential surface of the material control plate. A material control ring for controlling the size of the feed inlet is fixedly arranged on the left end face of the material control plate. The guide sleeves are fixedly arranged on the right end face of the corresponding material control plates through a plurality of circumferentially distributed connecting frames.

[0015] According to a preferred embodiment, the annular area of the material control ring is in the shape of a frustum of a cone with a smaller left end and a larger right end, and the larger the diameter of the feed hole on the material control plate corresponding to the material control ring, the larger the left end diameter of the annular area of the material control ring.

[0016] According to an advantageous embodiment, sealing tube barrels fixedly arranged on the mounting plate are provided on the left sides of the remaining feed inlets except the uppermost feed inlet. The sealing tube barrels communicate with the corresponding feed inlets. When the guiding circular sleeves that are not in the feeding process are inserted into the corresponding feed inlets during feeding to avoid interference and perform subsequent cleaning operations.

[0017] According to an advantageous embodiment, the cleaning group includes a mounting plate. The mounting plate is fixedly installed on the lateral inner wall of the sealing tube barrel. A plurality of cleaning strips made of rubber are fixedly arranged on the mounting plate. The distribution of all the cleaning strips on the mounting plate is the same as the distribution of the feed inlets on the corresponding material control plate. When the guiding circular sleeve corresponding to the material control plate rotates to face the corresponding sealing tube barrel and is inserted into the sealing tube barrel, the cleaning strips are used to clean the material control plate to prevent blockage.

[0018] In summary, the present invention has at least one of the following beneficial effects: In the present invention, the corresponding adapted material control plates are selected for corresponding assembly according to the particle diameter of the fed materials. At the same time, during the feeding process, the corresponding material control plates are switched to face the corresponding materials. Through the material control process of the material control plates and the material control rings, the actual feeding amount of the overall materials is controlled, avoiding excessive actual feeding amount of small-particle materials from affecting the subsequent mixing process, improving the mixing uniformity among multiple subsequent materials. Secondly, the detachable assembly method not only adapts to the feeding processes of different materials but also improves the practicality of the feeding structure. Moreover, the sealing tube barrels can not only block the guiding circular sleeves and the corresponding pipelines, but also, when docking for feeding, the feeding holes on the corresponding material control plates of the remaining sealing tube barrels cooperate with the cleaning strips to clean the material control plates and avoid blockage.

Detailed implementation manners

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] As Figure 1 and Figure 2 shown, a multi-tube feeding structure of a chemical reactor is provided on the reactor and docked with the feeding pipe of the reactor, including: a mounting disc 1, a docking part 2 for locking the mounting disc 1 is provided between the mounting disc 1 and the reactor, a rotating shaft 3 with an axis extending from left to right is rotatably provided on the mounting disc 1, a docking disc 4 is movably sleeved on the rotating shaft 3, and a feeding mechanism 5 is jointly provided on the docking disc 4 and the mounting disc 1.

[0029] As Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the feeding mechanism 5 includes a feeding port 50. A plurality of circumferentially distributed feeding ports 50 are provided on the docking plate 4. All the feeding ports 50 are connected to an external existing feeding pump (not shown in the figure) through corresponding pipelines. The corresponding materials are sequentially transported into the reactor by the feeding pump for mixing. A plurality of circumferentially distributed through-holes 51 are penetrated through the mounting plate 1. The uppermost through-hole 51 is docked with the feeding pipe. A material control part 52 for controlling the uniformity of material feeding is arranged in all the feeding ports 50.

[0030] As Figure 4 , Figure 5 and Figure 6 shown, the material control part 52 includes a material control plate 520. The material control plate 520 is arranged in the feeding port 50. Feeding holes 521 are provided on the material control plate 520. The diameters of the feeding holes 521 on different material control plates 520 are different, and the number of the feeding holes 521 with larger diameters is smaller.

[0031] As Figure 2 , Figure 4 and Figure 6 shown, a docking unit 53 for guiding the docking of the feeding port 50 and the uppermost through-hole 51 is arranged on the docking plate 4. The docking unit 53 includes a cleaning group 530. When one of the feeding ports 50 is docked with the uppermost through-hole 51, the cleaning group 530 cleans the material control plate 520 in the remaining feeding ports 50.

[0032] During operation, the mounting plate 1 is installed on the feeding pipe of the reactor through the docking part 2. Then, according to the particle size of the material to be fed into the reactor, the corresponding pipeline of the material is connected to the corresponding feeding port 50 on the docking plate 4 (all are bolt connections). Thus, the assembly process of the feeding structure is completed. Then, during the feeding process, when the corresponding pipeline is opposite to the uppermost through-hole 51, the pipeline is in a state of waiting for feeding, and the remaining pipelines are in a rest state. The docking unit 53 is used to dock the pipeline with the uppermost through-hole 51. Therefore, the corresponding material control plate 520 is connected to the feeding flow path. At this time, the corresponding external feeding pump works to make the material enter the feeding pipe through the feeding holes 521 on the material control plate 520 and the uppermost through-hole 51, and finally enter the reactor to complete the feeding action. Then, according to the feeding sequence of the required materials, the corresponding pipeline is switched by rotating the rotating shaft 3 and the docking plate 4, so that the corresponding pipeline is communicated with the uppermost through-hole 51, and the feeding action is repeated. Thus, the multi-pipe sequential feeding process of a variety of different materials at the feeding pipe is carried out through the multi-pipe switching method.

[0033] It should be noted that in the above process, the feeding process of materials with different diameters is adapted through the material control plate 520, that is, the feeding process of materials with corresponding diameters is limited by the feeding holes 521 with corresponding aperture sizes, avoiding the problem that the excessive feeding amount of small-diameter materials affects the subsequent mixing uniformity of materials, and assisting the multi-pipe feeding process of different materials.

[0034] As Figure 1 , Figure 2 and Figure 3 shown, the docking part 2 includes bolts 20. A plurality of axially distributed bolts 20 are fixedly arranged on the right end face of the mounting plate 1. The bolts 20 penetrate through the mounting holes of the upper flange of the feeding pipe. A docking frame 21 is commonly penetrated through some of the bolts 20. The docking frame 21 is located on the right side of the upper flange of the feeding pipe. Nuts are threadedly installed on the bolts 20. The docking frame 21 is also connected to the reactor through bolts 20.

[0035] During the process of connecting the feeding mechanism 5 to the reactor, first, the bolts 20 on the mounting plate 1 are penetrated into the mounting holes of the upper flange of the feeding pipe, and then the docking frame 21 is placed on the right side of the upper flange of the feeding pipe. The docking frame 21 and the mounting plate 1 are tightened by tightening the nuts. Thus, the docking between the mounting plate 1 and the feeding pipe is completed. The uppermost through port 51 is communicated with the inside of the feeding pipe. Secondly, it should be noted that the docking strength between the mounting plate 1 and the feeding pipe is improved through the docking frame 21, ensuring the stability of the subsequent multi-pipe feeding process switching.

[0036] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a ring-shaped frame 54 is fixedly arranged on the left end face of the mounting plate 1. The inner arc surface of the ring-shaped frame 54 is in close contact with the docking plate 4. Guide circular sleeves 55 corresponding to the material control plates 520 are arranged on the right end face of the docking plate 4. In order to guide the guide circular sleeves 55 to be inserted into the through port 51, the left inner wall of the through port 51 is chamfered. The docking plate 4 is driven by an external hydraulic cylinder to move left and right (not shown in the figure). The docking plate 4 is slidably sleeved on the rotating shaft 3 left and right. The right end of the rotating shaft 3 is connected to an external motor (not shown in the figure).

[0037] As Figure 3 and Figure 4As shown, a fitting plate 56 is slidably sleeved on the left and right of the rotating shaft 3. The guiding circular sleeve 55 slidably penetrates through the fitting plate 56. Rubber rings 560 corresponding to the guiding circular sleeves 55 are fixedly arranged on the right end face of the fitting plate 56. When the fitting plate 56 presses the mounting disc 1, the sealing effect is enhanced by tightly attaching to the chamfer of the through port 51 through the rubber rings 560. A compression spring 57 sleeved on the rotating shaft 3 is fixedly arranged between the fitting plate 56 and the docking disc 4. A pressing circular sleeve 58 is fixedly arranged on the right end face of the docking disc 4. The rotating shaft 3 and the compression spring 57 penetrate through the pressing circular sleeve 58.

[0038] As Figure 4 and Figure 5 shown, the material control part 52 further includes L-shaped grooves 522. Groove groups corresponding to the feed ports 50 are formed on the right end face of the docking disc 4. The groove groups include a plurality of L-shaped grooves 522 evenly distributed in the circumferential direction. Mounting blocks 523 are fixedly arranged on the circumferential surface of the material control plate 520. A material control ring 524 for controlling the size of the feed port 50 is fixedly arranged on the left end face of the material control plate 520. The guiding circular sleeves 55 are fixedly arranged on the right end faces of the corresponding material control plates 520 through a plurality of circumferentially distributed connecting frames.

[0039] As Figure 4 and Figure 6 shown, the annular area of the material control ring 524 is in the shape of a frustum with a smaller left end and a larger right end. Moreover, the larger the diameter of the feed hole 521 on the material control plate 520 corresponding to the material control ring 524, the larger the left end diameter of the annular area of the material control ring 524, thereby controlling the size of the cross-section of the feed area.

[0040] Before installing the mounting disc 1 onto the feed pipe, the external hydraulic cylinder operates to move the docking disc 4 to the left, so that the docking disc 4 withdraws from the annular area of the annular frame 54. Then, the operator selects the corresponding material control plate 520 and material control ring 524 according to the material corresponding to the pipeline, and installs the material control plate 520, the material control ring 524, and the guiding circular sleeve 55 at the corresponding feed port 50. The specific installation method is as follows: The operator holds the guiding circular sleeve 55 and makes the material control plate 520 and the material control ring 524 enter the feed port 50. The mounting block 523 gradually enters the left bottom of the L-shaped groove 522 from right to left along the horizontal section of the L-shaped groove 522. Then, the guiding circular sleeve 55 is rotated so that the mounting block 523 is stuck into the circumferential section of the L-shaped groove 522. Thus, the rotation and installation process of the material control plate 520 is completed. After the installation is completed, the external hydraulic cylinder operates to move the docking disc 4 to the right to reset.

[0041] During the continuous rightward movement of the docking plate 4, the docking plate 4 drives the fitting plate 56 thereon into contact with the left end face of the mounting plate 1. As the docking plate 4 continues to move rightward, the compression spring 57 is compressed. The elastic force generated by the compression of the compression spring 57 causes the fitting plate 56 to tightly adhere to the right end face of the mounting plate 1. In this state, the right side of the guiding circular sleeve 55 is flush with the right side of the fitting plate 56. This state is the state to be operated. Then, the external motor works to drive the rotating shaft 3 to rotate, and the rotating shaft 3 drives the mounting plate 1 and the guiding circular sleeve 55 to rotate synchronously, thereby adjusting the circumferential positions of the guiding circular sleeve 55 and the material control plate 520. When the guiding circular sleeve 55 corresponding to the pipeline for feeding material is left-right opposite to the uppermost through hole 51, the external motor stops operating, and the external hydraulic cylinder works to make the docking plate 4 move rightward. The guiding circular sleeve 55 is inserted into the uppermost through hole 51. Thus, the pipeline corresponding to the material is connected to the feed pipe through the corresponding feed port 50 and the guiding circular sleeve 55. During the above process, the guiding circular sleeve 55 not only plays a connecting role but also can guide the docking process.

[0042] After that, as the external hydraulic cylinder continues to operate and makes the docking plate 4 continue to move rightward, finally the docking plate 4 drives the pressing circular sleeve 58 thereon to press the fitting plate 56 tightly. At this time, the fitting plate 56 is rigidly pressed onto the mounting plate 1. During the process of the fitting plate 56 adhering to the mounting plate 1 until it is rigidly pressed, the rubber ring 560 is pressed and deformed, improving the tightness of the docking between the fitting plate 56, the guiding circular sleeve 55, and the through hole 51, and avoiding the problem of leakage during the switching process.

[0043] Thus, the feeding process of the material begins. After completing the feeding operation of this kind of material, the external hydraulic cylinder works to reset, making the fitting plate 56 and the guiding circular sleeve 55 return to the state to be operated. The external motor works to make the guiding circular sleeve 55 corresponding to another kind of material be docked, repeating the above process to carry out the feeding process of this kind of material. In summary, repeating the above process multiple times to carry out the multi-pipe feeding operation of multiple materials.

[0044] In addition, it should be noted separately that during the feeding process, the feeding hole 521 on the material control plate 520 controls the size of the feeding material diameter, and the size of the annular area of the corresponding control ring 524 correspondingly controls the size of the cross-section of the feeding area. That is, before installation, select the material control plate 520 and the control ring 524 with appropriate sizes according to the size of the material diameter required for feeding, so as to adapt to the feeding process of different material diameters, making the feeding amounts of large-diameter materials and small-diameter materials more balanced per unit time, avoiding the excessive feeding amount of small-diameter materials from affecting the subsequent material mixing uniformity. Secondly, the above detachable assembly method improves the convenience and practicality of the feeding structure.

[0045] Such as Figure 3 and Figure 5As shown, on the left side of the remaining feed inlets 50 except for the uppermost feed inlet 50, there is a sealing tube barrel 531 fixedly arranged on the mounting plate 1. The sealing tube barrel 531 communicates with the corresponding feed inlet 50. When feeding is not in progress, the guiding circular sleeve 55 is inserted into the corresponding feed inlet 50 during feeding for avoidance and subsequent cleaning operations.

[0046] As Figure 4 and Figure 6 As shown, the cleaning group 530 includes a mounting plate 5300. The lateral inner wall of the sealing tube barrel 531 is fixedly installed with the mounting plate 5300. A plurality of cleaning strips 5301 made of rubber are fixedly arranged on the mounting plate 5300. The distribution of all the cleaning strips 5301 on the mounting plate 5300 is the same as the distribution of the feed holes 521 on the corresponding material control plate 520. When the guiding circular sleeve 55 corresponding to the material control plate 520 rotates to face the corresponding sealing tube barrel 531 and is inserted into the sealing tube barrel 531, the material control plate 520 is cleaned and blocked by the cleaning strips 5301. When the feed holes 521 on the material control plate 520 corresponding to the guiding circular sleeve 55 facing the sealing tube barrel 531 do not correspond to the cleaning strips 5301, the cleaning strips 5301 are deformed under the extrusion of the material control plate 520, and it will not affect the horizontal movement of the guiding circular sleeve 55.

[0047] During the process of the uppermost guiding circular sleeve 55 being inserted into the uppermost through hole 51, the remaining guiding circular sleeves 55 synchronously enter the remaining corresponding through holes 51, and this part of the guiding circular sleeves 55 enter the corresponding sealing tube barrels 531 through the corresponding through holes 51 to block the guiding circular sleeves 55 and the corresponding pipelines, avoiding the outflow of the materials remaining in the guiding circular sleeves 55 and the pipelines. Secondly, when this part of the guiding circular sleeves 55 move into the corresponding sealing tube barrels 531 (at this time, the feed holes 521 on the material control plate 520 corresponding to the guiding circular sleeves 55 cooperate with the cleaning strips 5301 in the sealing tube barrels 531), so during the butt joint feeding, the feed holes 521 on the remaining material control plates 520 cooperate with the cleaning strips 5301 to clean the material control plates 520, avoiding the problem of blockage.

[0048] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0049] In addition, the terms "first", "second", "No. 1", and "No. 2" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", "No. 1", or "No. 2" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0050] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "arranged", "connected", "installed", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
