Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of conveying, and particularly relates to introducing materials into a container, and especially relates to a feeding pipe device of a reaction kettle and a working method. BACKGROUND

[0002] The reaction kettle is a container for chemical reactions, and through structural design and parameter configuration of the container, functions of heating, evaporation, cooling and mixing required by a process are realized. In chemical production, a feeding system of the reaction kettle is a key link for ensuring continuity and safety of production.

[0003] At present, a special feeding device is usually provided for a large reaction kettle, and materials are conveyed from a storage hopper to the inside of the reaction kettle through a conveying pipeline. However, the prior art has obvious defects: after feeding is completed, some materials are left on the inner wall of the feeding pipe. Due to long-time residence, the residual materials gradually form a “bridge” phenomenon (i.e., an arch-shaped structure of the materials in the pipeline hinders the flow of subsequent materials), which seriously affects the speed and efficiency of the next feeding. In particular, for powder or easily adhering materials, this problem is more prominent, which not only increases energy consumption, but also may cause production proportion imbalance, affecting product quality.

[0004] Traditionally, the feeding pipe and the reaction kettle are directly connected, and only a simple valve is used to close the connection after feeding is completed. Since the feeding pipe is connected with the hopper at the same time, this design leads to low sealing requirement, and toxic and harmful gases generated by chemical reactions in the reaction kettle may escape and leak to the feeding pipe through the gap of the connection.

[0005] Therefore, how to avoid the escape of toxic and harmful gases through the feeding pipe is a technical problem to be solved in the field.

[0006] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background of the present application, and therefore, the above description is not considered as information of the related art. SUMMARY

[0007] The present application provides at least a feeding pipe device of a reaction kettle and a working method thereof.

[0008] In a first aspect, the present application provides a feeding pipe device of a reaction kettle, comprising: a base disc arranged at the top of the reaction kettle; a feeding pipe arranged at the upper end of the base disc, and an inner layer pipe is arranged in the feeding pipe, and a gas cavity is formed between the outer wall of the inner layer pipe and the inner wall of the feeding pipe; a gas inlet pipe arranged on the outer wall of the feeding pipe, used for conveying dry gas into the gas cavity; a sealing plate slidingly arranged in the base disc, and the two sealing plates slide along the radial direction of the base disc to open and close the inner layer pipe. an adjusting member rotatably arranged in the feeding pipe and linked with the sealing plates; When the two sealing plates move towards each other, the adjusting member is driven to rotate forward, and the first air holes on the partition pipe are opened to allow dry gas to flow into the partition pipe. When the two sealing plates move away from each other, the adjusting member is driven to rotate reversely, and the first air holes on the partition pipe are closed, and the pressure in the air cavity is increased to vibrate the adjusting member relative to the base disc.

[0009] In an alternative embodiment, the adjusting member comprises an adjusting ring rotatably arranged above the sealing plates. An adjusting pipe is vertically arranged on the adjusting ring, and the inner wall of the adjusting pipe is in close contact with the outer wall of the partition pipe. The adjusting pipe is circumferentially provided with a plurality of second air holes, and each second air hole corresponds to a first air hole. When the adjusting ring rotates forward, the adjusting pipe rotates relative to the partition pipe to completely overlap the first air holes and the second air holes. When the adjusting ring rotates reversely, the adjusting pipe rotates relative to the partition pipe to misalign the first air holes and the second air holes.

[0010] In an alternative embodiment, a linkage column is arranged on the sealing plate, and the height of the linkage column is greater than the thickness of the adjusting ring. The adjusting ring is circumferentially provided with two sliding grooves, and one linkage column is slidingly arranged in one sliding groove. When the two sealing plates move towards or away from each other, the linkage column moves in the sliding groove to push the adjusting ring to rotate forward or reversely.

[0011] In an alternative embodiment, the sliding grooves are in the shape of circular arcs, and the distance between one end of the sliding groove and the other end gradually increases from the center of the adjusting ring.

[0012] In an alternative embodiment, a sealing disc is arranged on the inner wall of the feeding pipe, and the sealing disc is located above the adjusting ring, and the inner ring of the sealing disc is in rotational sealing with the outer wall of the adjusting pipe.

[0013] In an alternative embodiment, the distance between the bottom wall of the sealing disc and the sealing plate is greater than the axial thickness of the adjusting ring. When the first air holes and the second air holes are misaligned, the pressure in the air cavity is increased to push the adjusting pipe to move downward to vibrate the adjusting ring.

[0014] In an alternative embodiment, the width of the sealing plate is greater than the inner diameter of the inner ring of the adjusting pipe, and when the two sealing plates move towards each other to abut, the partition pipe is closed.

[0015] In an alternative embodiment, the inner diameter of the adjusting ring is not greater than the inner diameter of the partition tube, wherein when the pressure in the air cavity increases and pushes the adjusting ring to vibrate, the adjusting ring is adapted to hit the bottom wall of the partition tube.

[0016] In an alternative embodiment, the feeding tube is vertically arranged at the upper end of the base disc and internally arranged with a partition tube, and an air cavity is formed between the outer wall of the partition tube and the inner wall of the feeding tube. The partition tube is circumferentially arranged with a plurality of first air holes. The sealing plates are slidingly arranged in the base disc, and the two sealing plates slide along the radial direction of the base disc to open and close the partition tube. The adjusting ring is rotationally arranged above the sealing plates and is linked with the sealing plates. The adjusting tube is vertically arranged on the adjusting ring and the inner wall of the adjusting tube is attached to the outer wall of the partition tube. The adjusting tube is circumferentially arranged with a plurality of second air holes, and one second air hole corresponds to one first air hole. When the adjusting ring rotates in the forward direction, the adjusting tube rotates relative to the partition tube to make the first air holes completely coincide with the second air holes. When the adjusting ring rotates in the reverse direction, the adjusting tube rotates relative to the partition tube to make the first air holes misaligned with the second air holes.

[0017] In an alternative embodiment, a linkage column is arranged on the sealing plate, and the height of the linkage column is greater than the thickness of the adjusting ring. The adjusting ring is circumferentially and symmetrically arranged with two sliding grooves, and one linkage column is slidingly arranged in one sliding groove. The sliding grooves are in the shape of a circular arc, and the distance between one end of the sliding groove and the other end gradually increases from the center of the adjusting ring. When the two sealing plates move towards or away from each other, the linkage column moves in the sliding groove to push the adjusting ring to rotate in the forward or reverse direction.

[0018] In a second aspect, the embodiments of the present disclosure further provide a working method of a reaction kettle feeding tube device, which comprises the following steps: When feeding, the two sealing plates move away from each other to open the partition tube, and when the two sealing plates move away from each other, the adjusting member is driven to rotate in the reverse direction, the adjusting member rotates in the reverse direction to close the first air holes arranged on the partition tube, and the pressure in the air cavity increases to make the adjusting member vibrate relative to the base disc. After the feeding is completed, the two sealing plates move towards each other to close the partition tube, and the adjusting member is driven to rotate in the forward direction, the adjusting member rotates in the forward direction to open the first air holes arranged on the partition tube, so that dry gas flows into the partition tube.

[0019] The beneficial effect of the present application is that the present application provides a reaction kettle feeding pipe device and a working method, through the cooperation of the two sealing plates and the adjusting piece, the technical problems of material residue and "bridge" of the feeding pipe are solved; when the feeding is finished and the two sealing plates move away to close the partition pipe, the sealing plate linkage drives the adjusting piece to rotate reversely, and the first air hole is closed. This makes the dry gas input from the air inlet pipe be closed in the air cavity, and the pressure rises rapidly. The accumulated gas pressure will push the adjusting piece to vibrate relative to the base disc. This vibration is transmitted to the inside of the feeding pipe through the partition pipe, and forms effective impact and shake-off on the residual material that may be attached to the pipe wall, especially the easily adhered powder, so as to destroy the "bridge" trend and ensure the smoothness of the next feeding.

[0020] Other features and advantages of the present application will be set forth in the following description, and in part will become apparent to those skilled in the art from the description, or can be learned by practice of the present application. The objects and other advantages of the present application will be realized and achieved by the structure particularly pointed out in the description and the drawings.

[0025] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the present application.

In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components can be exaggerated or reduced.

[0027] In this document, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0028] The terminology used herein is for the purpose of describing particular example configurations only and is not intended to be limiting. As used herein, the singular articles "a," "an," and "the" can be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises," "comprising," "including," and "having" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

Thus, features, structures, or characteristics can be included in more than one embodiment of the present disclosure, and the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” and the like are not necessarily referring to the same embodiment. As used herein, the terms “for example,” “e.g.,” and the like indicate that the named item is a non-exclusive example. Any embodiment, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” and the like is intended to present concepts in a concrete manner.

[0030] It is found through research that the reaction kettle is a container for chemical reactions, and through the structural design and parameter configuration of the container, the functions of heating, evaporation, cooling and mixing required by the process are realized. In chemical production, the feeding system of the reaction kettle is the key link to ensure the continuity and safety of production.

[0031] At present, large reaction kettles are usually equipped with special feeding devices, and the materials are transported from the storage hopper to the inside of the reaction kettle through the conveying pipeline. However, the existing technology has obvious defects: after the feeding is completed, there will be some residual materials on the inner wall of the feeding pipe. These residual materials will gradually form a “bridge” phenomenon (i.e. the material forms an arch structure in the pipeline, which hinders the flow of subsequent materials), which seriously affects the speed and efficiency of the next feeding. Especially for powders or materials prone to sticking, this problem is more prominent, not only increasing energy consumption, but also possibly leading to production proportion imbalance, affecting product quality.

[0032] Traditionally, the feeding pipe and the reaction kettle are directly connected, and after the feeding is completed, the connection is simply closed by a valve. Due to the fact that the feeding pipe is connected to the hopper at the same time, this design results in a low sealing requirement and structural defects. The toxic and harmful gases generated by the chemical reaction in the reaction kettle may escape through the gap of the connection to the feeding pipe, eventually leaking into the working environment.

[0033] Therefore, it is necessary to provide a reaction kettle feeding pipe device and a working method that can effectively prevent residual material bridging and have good sealing performance.

[0034] The defects of the above-mentioned solutions and the causes thereof are the results obtained by the inventors after practice and careful research, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to solve the above-mentioned problems should be the contributions made by the inventors to the present disclosure in the process of the present disclosure.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] like Figure 1 As shown, at least one embodiment provides a reactor feeding pipe device, including: a base plate 2, which is disposed on the top of the reactor 1; the base plate 2 is fixedly installed on the top feed inlet of the reactor 1 by means of a flange connection, serving as the basic support component for the entire feeding and loading process. A feeding pipe 3 is disposed on the upper end of the base plate 2, with the lower end of the feeding pipe 3 communicating with the interior of the base plate 2, and the upper end used to connect to a feeding pipe (not shown in the figure) from a silo. A partition pipe 31 is concentrically disposed inside the feeding pipe 3, and an air cavity 30 is formed between the outer wall of the partition pipe 31 and the inner wall of the feeding pipe 3; an air inlet pipe 4 is disposed on the outer wall of the feeding pipe 3 for supplying dry gas into the air cavity 30; the air inlet pipe 4 is welded or threaded to the outer wall of the feeding pipe 3 and communicates with the air cavity 30. The other end of the air inlet pipe 4 is connected to an external air source (such as a dry air generator) for continuously supplying dry gas into the air cavity 30.

[0038] Reference Appendix Figure 2 The sealing plates 20 are slidably disposed within the base plate 2. The two sealing plates 20 slide radially along the base plate 2 to open and close the partition tube 31. The base plate 2 also contains two driving mechanisms (not shown in the figure), which drive the sealing plates 20 to reciprocate radially along the base plate 2. Furthermore, the driving mechanisms can be linear drive mechanisms such as cylinders, hydraulic cylinders, or electric push rods, to achieve the movement of the two sealing plates 20 towards each other (closing the partition tube 31) or away from each other (opening the partition tube 31). To ensure a sealing effect, a sealing ring is provided between the sliding surface of the sealing plate 20 and the base plate 2. Preferably, the width of the sealing plate 20 is greater than the inner diameter of the partition tube 31. When the two sealing plates 20 move towards each other until they abut against each other, they can completely close the bottom opening of the partition tube 31, forming a reliable seal.

[0039] Reference Appendix Figure 3, the adjusting member 5 is rotationally arranged in the feeding pipe 3 and is linked with the sealing plates 20; when the two sealing plates 20 move towards each other, the adjusting member 5 is driven to rotate forward, and the first air holes 32 opened on the partition pipe 31 are opened by the forward rotation of the adjusting member 5, so that dry gas flows into the partition pipe 31; when the two sealing plates 20 move away from each other, the adjusting member 5 is driven to rotate reversely, and the first air holes 32 opened on the partition pipe 31 are closed by the reverse rotation of the adjusting member 5, and the pressure in the air cavity 30 increases to make the adjusting member 5 vibrate relative to the base disc 2. Through the cooperation of the two sealing plates 20 and the adjusting member 5, the technical problems of material residue and "bridge" in the feeding pipe 3 are solved; when the feeding is finished and the two sealing plates 20 move away from each other to close the partition pipe 31, the sealing plates 20 link to drive the adjusting member 5 to rotate reversely, and the first air holes 32 are closed. This makes the dry gas input from the air inlet pipe 4 be closed in the air cavity 30, and the pressure rapidly increases. The accumulated gas pressure will push the adjusting member 5 to vibrate relative to the base disc 2. This vibration is transmitted to the inside of the feeding pipe 3 through the partition pipe 31, and forms effective impact and shake-off on the residual material possibly attached to the pipe wall, especially the easily adhered powder, so as to destroy the "bridge" tendency and ensure the smoothness of the next feeding.

[0040] Reference is made to the accompanying drawings Figure 3 The adjusting member 5 comprises: an adjusting ring 51 rotationally arranged above the sealing plate 20; and an adjusting pipe 52 vertically arranged on the adjusting ring 51 and having an inner wall abutting against the outer wall of the partition pipe 31, and the inner wall of the adjusting pipe 52 and the outer wall of the partition pipe 31 are precisely abutted, which can slide relative to each other and maintain good air tightness. A plurality of first air holes 32 are uniformly opened on the wall of the partition pipe 31 in the circumferential direction. Correspondingly, a plurality of second air holes 53 are also uniformly distributed on the wall of the adjusting pipe 52 in the circumferential direction, and the number and position of the second air holes 53 correspond to the first air holes 32 one by one. When the adjusting ring 51 rotates forward, the adjusting pipe 52 rotates relative to the partition pipe 31, so that the first air holes 32 and the second air holes 53 completely coincide; when the adjusting ring 51 rotates reversely, the adjusting pipe 52 rotates relative to the partition pipe 31, so that the first air holes 32 and the second air holes 53 are misaligned.

[0041] Reference is made to the accompanying drawings Figure 3 In order to realize the linkage of the sealing plate 20 and the adjusting member 5, a linkage column 21 is fixedly arranged on the upper surface of each sealing plate 20. The height of the linkage column 21 is greater than the thickness of the adjusting ring 51. Two sliding grooves 54 are symmetrically opened on the adjusting ring 51 in the circumferential direction. The upper end of each linkage column 21 respectively extends into one sliding groove 54. The sliding groove 54 is not a straight groove, but a circular arc shape. The centers of the circular arcs do not coincide with the center of the adjusting ring 51, so that the distance from one end of the sliding groove 54 to the center of the adjusting ring 51 gradually increases to the other end (i.e. it is an eccentric circular arc groove).

[0042] Reference Appendix Figure 4 F1 indicates the direction in which the two sealing plates 20 move away from each other, at which time the partition tube 31 is in the open state; in this state, the adjusting ring 51 rotates in the opposite direction, that is, it rotates in the direction shown by F4. F2 indicates the direction in which the two sealing plates 20 move towards each other, at which time the partition tube 31 is in a closed state; in this state, the adjusting ring 51 rotates in the positive direction, that is, it rotates in the direction shown by F3.

[0043] Reference Appendix Figure 3 A sealing disc 33 is provided on the inner wall of the feeding pipe 3. The sealing disc 33 is located above the adjusting ring 51, and the inner ring of the sealing disc 33 rotates and seals with the outer wall of the adjusting pipe 52. The cooperation between the sealing disc 33, the feeding pipe 3, and the partition pipe 31 improves the sealing performance of the air chamber 30. The distance from the bottom wall of the sealing disc 33 to the sealing plate 20 is greater than the axial thickness of the adjusting ring. When the first air hole 32 and the second air hole 53 are misaligned, the pressure inside the air chamber 30 increases, pushing the adjusting pipe 52 downward to vibrate the adjusting ring 51. The inner diameter of the adjusting ring 51 is not greater than the inner diameter of the partition pipe 31. When the pressure inside the air chamber 30 increases and pushes the adjusting ring 51 to vibrate, the adjusting ring 51 is suitable for impacting the bottom wall of the partition pipe 31.

[0044] Reference Appendix Figure 2 At least one embodiment provides a reactor feeding pipe device, comprising: a feeding pipe 3, which is vertically disposed on the upper end of a base plate 2, and has a partition pipe 31 disposed inside it, wherein an air cavity 30 is formed between the outer wall of the partition pipe 31 and the inner wall of the feeding pipe 3; a plurality of first air holes 32 are evenly distributed around the partition pipe 31; a sealing plate 20, which is slidably disposed in the base plate 2, and the two sealing plates 20 slide radially along the base plate 2 to open and close the partition pipe 31; and an adjusting ring 51, which is rotatably disposed above the sealing plate 20 and is in contact with the sealing plate. 20 linkage; adjustment tube 52, which is vertically arranged on adjustment ring 51, and its inner wall is in contact with the outer wall of the partition tube 31; the adjustment tube 52 is evenly distributed with a plurality of second air holes 53, and one second air hole 53 corresponds to one first air hole 32; wherein, when the adjustment ring 51 rotates in the forward direction, the adjustment tube 52 rotates relative to the partition tube 31 so that the first air hole 32 and the second air hole 53 completely overlap; when the adjustment ring 51 rotates in the reverse direction, the adjustment tube 52 rotates relative to the partition tube 31 so that the first air hole 32 and the second air hole 53 are misaligned.

[0045] At least one embodiment provides a method for operating a reactor feed pipe device, the method comprising: During feeding, the two sealing plates 20 move apart to open the partition tube 31. When the two sealing plates 20 move apart, they drive the adjusting member 5 to rotate in the opposite direction. The adjusting member 5 rotates in the opposite direction to close the first air hole 32 opened on the partition tube 31. The pressure in the air chamber 30 increases, causing the adjusting member 5 to vibrate relative to the base plate 2. After the material is fed, the two sealing plates 20 move towards each other to close the partition tube 31, driving the adjusting member 5 to rotate in the forward direction. The adjusting member 5 rotates in the forward direction to open the first air hole 32 on the partition tube 31 so that the dry gas flows into the partition tube 31.

[0046] The working principle of the feed pipe 3 device in reactor 1 is as follows: During feeding, the external drive mechanism pushes the two sealing plates 20 to move apart, opening the bottom channel of the partition tube 31. As the sealing plates 20 move, the linkage column 21 on them slides within the sliding groove 54. Due to the eccentric arc design of the sliding groove 54, the linkage column 21 generates a tangential force on the groove wall, pushing the adjusting ring 51 to rotate in the opposite direction. The adjusting ring 51 drives the adjusting tube 52 to rotate in the opposite direction, causing the second air hole 53 to be completely misaligned and closed with the first air hole 32. The air inlet pipe 4 continuously supplies air, but because the air path is cut off, the pressure in the air chamber 30 begins to accumulate rapidly. The pressure in the air chamber 30 pushes the adjusting ring 51 and the adjusting tube 52 downward, thereby generating vibration. The vibration of the adjusting ring 51 relative to the partition tube 31 can prevent the material accumulated in the partition tube 31 from forming a "bridging" phenomenon, thus preventing the partition tube 31 from becoming blocked.

[0047] After feeding is completed, the external drive mechanism pushes the two sealing plates 20 to move towards each other until they abut against each other, thereby sealing the bottom of the partition tube 31. The movement of the sealing plates 20 towards each other causes the linkage column 21 to move forward in the sliding groove 54, driving the adjusting ring 51 to rotate forward. The adjusting ring 51 drives the adjusting tube 52 to rotate forward, so that the second air hole 53 on the adjusting tube 52 is completely aligned and overlapped with the first air hole 32 on the partition tube 31. At this time, the dry gas in the gas chamber 30 can flow smoothly into the partition tube 31 through the overlapping air holes to dry the material temporarily accumulated in the partition tube 31. Since the sealing plate 20 closes the channel for feeding into the reactor 1, the air inlet pipe 4 continuously delivers dry gas into the gas chamber 30, which increases the pressure in the gas chamber 30 and the partition tube 31. The increased pressure in the gas chamber 30 not only prevents the material from flowing into the gas chamber 30 through the first air hole 32 and the second air hole 53, but also allows the dry gas and the material accumulated in the partition tube 31 to work together to balance the pressure difference between the upper and lower parts of the sealing plate 20, preventing harmful gases generated by the chemical reaction in the reactor 1 from leaking out through the partition tube 31.

[0048] like Figure 3As shown, a sealing disc 33 is fixedly installed on the inner wall of the feeding pipe 3, and its inner ring forms a rotational seal with the outer wall of the regulating pipe 52 (allowing the regulating pipe 52 to rotate relative to each other while maintaining airtightness). When the two sealing plates 20 move apart to close the first air hole 32, the air inlet pipe 4 continuously inputs dry gas into the air chamber 30. Since the air outlet is cut off, the pressure inside the air chamber 30 increases. The gas pressure mainly acts on the annular horizontal cross-section of the regulating pipe 52 ( Figure 3 The annular area between the regulating pipe 52 and the partition pipe 31 generates an upward axial force F_up (F_up = pressure × annular area of ​​regulating pipe 52).

[0049] The adjusting component 5 sits above the sealing plate 20 via the adjusting ring 51, but an axial clearance δ (approximately 0.5-1 mm) is designed between the adjusting ring 51 and the sealing plate 20. Figure 3 As shown. When the pressure in the air chamber 30 rises to a threshold (e.g., 0.1-0.2 MPa), F_up overcomes the weight and friction of the adjusting component 5, pushing the entire adjusting component 5 (including the adjusting ring 51 and the adjusting tube 52) upward slightly. After moving upward, a momentary gap appears between the sealing surface of the adjusting tube 52 and the sealing plate 33, and some gas inside the air chamber 30 leaks through the gap, causing a brief pressure drop. After F_up decreases, the adjusting component 5 falls back to its initial position under the action of gravity and reseals. This process occurs cyclically, forming a high-frequency micro-motion of the adjusting component 5 relative to the base plate 2 (the vibration frequency depends on the air supply pressure and the gap size).

[0050] Vibration is transmitted to the partition tube 31 through the adjusting ring 51: the inner diameter of the adjusting ring 51 is slightly smaller than the inner diameter of the partition tube 31. Figure 3 The gap between the regulating ring 51 and the bottom wall of the partition tube 31 is relatively small. During its up-and-down movement, it impacts the bottom wall of the partition tube 31, generating a shock wave. Simultaneously, the vibration of the regulating tube 52 directly acts on the outer wall of the partition tube 31, shaking off any adhering material. For example... Figure 4 As shown, the sealing plate 20 is tightly closed to prevent gas leakage from the reactor 1.

[0051] Through the above methods, the present invention ingeniously integrates the sealing, opening and closing of the pipeline with the regulation of airflow and the cleaning of residues, realizing automated and efficient operation, and significantly improving the reliability and safety of the feeding process of reactor 1.

[0052] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.
