Reaction kettle feeding pipe device and working method

Abstract

This invention belongs to the field of conveying technology, and particularly relates to a reactor feeding pipe device and its working method. One reactor feeding pipe device includes: a feeding pipe disposed on the upper end of a base plate, with a partition pipe inside, forming a gas cavity between the outer wall of the partition pipe and the inner wall of the feeding pipe; an inlet pipe disposed on the outer wall of the feeding pipe for conveying dry gas into the gas cavity; two sealing plates slidably disposed within the base plate, sliding radially along the base plate to open and close the partition pipe; and an adjusting member rotatably disposed within 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, opening a first air hole on the partition pipe 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 in the opposite direction, closing the first air hole on the partition pipe, increasing the pressure within the gas cavity and causing the adjusting member to vibrate relative to the base plate.

Description

Technical Field

[0001] This invention belongs to the field of conveying technology, specifically relating to the introduction of materials into containers, and more particularly to a feed pipe device for a reaction vessel and its working method. Background Technology

[0002] As a container for chemical reactions, the reactor achieves the required functions of heating, evaporation, cooling, and mixing through structural design and parameter configuration. In chemical production, the reactor's feeding system is a crucial link in ensuring production continuity and safety.

[0003] Currently, large reactors are typically equipped with dedicated feeding devices that transport materials from storage hoppers to the reactor interior via conveying pipes. However, existing technology has a significant drawback: after feeding, some material remains on the inner wall of the feeding pipe. This residual material, due to prolonged retention, gradually forms a "bridging" phenomenon (i.e., material forms an arched structure in the pipe, hindering the flow of subsequent materials), severely impacting the speed and efficiency of subsequent feedings. This problem is particularly pronounced for powders or easily agglomerated materials, not only increasing energy consumption but also potentially leading to production imbalances and affecting product quality.

[0004] Traditionally, the feed pipe is directly connected to the reactor, and the connection is simply closed with a valve after feeding is completed. Since the feed pipe is also connected to the silo, this design results in low sealing requirements, making it easy for toxic and harmful gases produced by the chemical reaction inside the reactor to escape and leak upwards through gaps in the connection.

[0005] Therefore, how to prevent toxic and harmful gases from overflowing through the feeding pipe is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Summary of the Invention

[0007] This disclosure provides at least one reactor feeding pipe device and its operating method.

[0008] In a first aspect, embodiments of this disclosure provide a reactor feeding pipe device, comprising:

[0009] A base plate, which is located at the top of the reactor;

[0010] The feeding pipe is located at the upper end of the base plate and has a partition pipe inside. An air cavity is formed between the outer wall of the partition pipe and the inner wall of the feeding pipe.

[0011] An air inlet pipe, which is located on the outer wall of the feed pipe, is used to deliver dry gas into the air chamber;

[0012] The sealing plates are slidably disposed within the base plate, and the two sealing plates slide radially along the base plate to open and close the partition tube;

[0013] An adjusting component is rotatably disposed inside the feeding pipe and is linked with the sealing plate;

[0014] When the two sealing plates move toward each other, they drive the adjusting member to rotate in the forward direction. The forward rotation of the adjusting member opens the first air hole on the partition tube so that the dry gas flows into the partition tube.

[0015] When the two sealing plates move apart, they drive the adjusting member to rotate in the opposite direction. The reverse rotation of the adjusting member closes the first air hole opened on the partition tube, and the pressure in the air chamber increases, causing the adjusting member to vibrate relative to the base plate.

[0016] In one alternative embodiment, the adjusting member includes an adjusting ring rotatably disposed above the sealing plate;

[0017] An adjusting tube is vertically mounted on the adjusting ring, and its inner wall is in contact with the outer wall of the partition tube.

[0018] The regulating tube is evenly distributed with a number of second air holes in its circumference, and one second air hole corresponds to one first air hole.

[0019] When the adjusting ring rotates in the forward direction, the adjusting tube rotates relative to the partition tube so that the first air hole and the second air hole completely overlap.

[0020] When the regulating ring rotates in the reverse direction, the regulating tube rotates relative to the partition tube, so that the first air hole and the second air hole are misaligned.

[0021] In one optional embodiment, a linkage post is provided on the sealing plate, and the height of the linkage post is greater than the thickness of the adjusting ring;

[0022] The adjusting ring has two symmetrical sliding grooves along its circumference, and a linkage column is slidably disposed in one of the sliding grooves; wherein, when the two sealing plates move toward each other or away from each other, the linkage column moves in the sliding groove to drive the adjusting ring to rotate in the forward and reverse directions.

[0023] In one alternative embodiment, the sliding groove is arc-shaped, and the distance between one end of the sliding groove and the center of the adjusting ring gradually increases from the other end.

[0024] In one optional embodiment, a sealing disc is provided on the inner wall of the feeding pipe, the sealing disc is located above the adjusting ring, and the inner ring of the sealing disc rotates and seals with the outer wall of the adjusting pipe.

[0025] In one optional embodiment, the distance from the bottom wall of the sealing disc to the sealing plate is greater than the axial thickness of the adjusting ring;

[0026] When the first air hole and the second air hole are misaligned, the pressure inside the air chamber increases, which pushes the regulating tube downward to vibrate the regulating ring.

[0027] In one alternative embodiment, the width of the sealing plate is greater than the inner diameter of the inner ring of the regulating tube, and when the two sealing plates move toward each other to abut, they are suitable for closing the partition tube.

[0028] In one optional embodiment, the inner diameter of the adjusting ring is not greater than the inner diameter of the partition tube, wherein when the pressure inside the air chamber increases and drives the adjusting ring to vibrate, the adjusting ring is adapted to strike the bottom wall of the partition tube.

[0029] In one optional embodiment, the feeding pipe is vertically disposed on the upper end of the base plate and has a partition pipe inside, and an air cavity is formed between the outer wall of the partition pipe and the inner wall of the feeding pipe.

[0030] The partition tube has several first air holes evenly distributed around its circumference;

[0031] The sealing plates are slidably disposed within the base plate, and the two sealing plates slide radially along the base plate to open and close the partition tube;

[0032] An adjusting ring is rotatably positioned above the sealing plate and is linked to the sealing plate.

[0033] An adjusting tube is vertically mounted on the adjusting ring, and its inner wall is in contact with the outer wall of the partition tube.

[0034] The regulating tube is evenly distributed with a number of second air holes in its circumference, and one second air hole corresponds to one first air hole.

[0035] When the adjusting ring rotates in the forward direction, the adjusting tube rotates relative to the partition tube so that the first air hole and the second air hole completely overlap.

[0036] When the regulating ring rotates in the reverse direction, the regulating tube rotates relative to the partition tube, so that the first air hole and the second air hole are misaligned.

[0037] In one optional embodiment, a linkage post is provided on the sealing plate, and the height of the linkage post is greater than the thickness of the adjusting ring;

[0038] The adjusting ring has two symmetrical sliding grooves along the circumference, and a linkage column is slidably set in one of the sliding grooves.

[0039] The sliding groove is arc-shaped, and the distance from one end of the sliding groove to the center of the adjusting ring gradually increases from the other end.

[0040] When the two sealing plates move toward each other or away from each other, the linkage column moves in the sliding groove to drive the adjusting ring to rotate in both directions.

[0041] Secondly, this disclosure also provides a method for operating a reactor feeding pipe device, the method comprising:

[0042] During feeding, the two sealing plates move apart to open the partition tube. When the two sealing plates move apart, they drive the adjusting member to rotate in the opposite direction. The adjusting member rotates in the opposite direction to close the first air hole opened on the partition tube. The pressure in the air chamber increases, causing the adjusting member to vibrate relative to the base plate.

[0043] After the material is fed, the two sealing plates move towards each other to close the partition tube, driving the adjusting member to rotate in the forward direction. The forward rotation of the adjusting member opens the first air hole on the partition tube, so that the dry gas flows into the partition tube.

[0044] The beneficial effects of this invention are that it provides a reactor feeding pipe device and its working method. Through the cooperation of two sealing plates and an adjusting component, it solves the technical problems of material residue and "bridging" in the feeding pipe. When feeding is completed and the two sealing plates move apart to close the partition pipe, the sealing plates drive the adjusting component to rotate in the opposite direction, closing the first vent. This causes the dry gas input from the inlet pipe to be sealed within the gas chamber, resulting in a rapid increase in pressure. The accumulated gas pressure drives the adjusting component to vibrate relative to the base plate. This vibration is transmitted through the partition pipe to the inside of the feeding pipe, effectively impacting and shaking off any residual material that may adhere to the pipe wall, especially easily agglomerated powders, thereby disrupting their "bridging" tendency and ensuring smooth feeding in the next cycle.

[0063] Research has shown that reactors, as containers for chemical reactions, achieve the required functions of heating, evaporation, cooling, and mixing through structural design and parameter configuration. In chemical production, the reactor's feeding system is a crucial link in ensuring production continuity and safety.

[0064] Currently, large reactors are typically equipped with dedicated feeding devices that transport materials from storage hoppers to the reactor interior via conveying pipes. However, existing technology has a significant drawback: after feeding, some material remains on the inner wall of the feeding pipe. This residual material, due to prolonged retention, gradually forms a "bridging" phenomenon (i.e., material forms an arched structure in the pipe, hindering the flow of subsequent materials), severely impacting the speed and efficiency of subsequent feedings. This problem is particularly pronounced for powders or easily agglomerated materials, not only increasing energy consumption but also potentially leading to production imbalances and affecting product quality.

[0065] Traditionally, the feed pipe is directly connected to the reactor, and the connection is simply closed with a valve after feeding. Because the feed pipe is also connected to the silo, this design results in low sealing requirements and structural defects. There is a technical problem that toxic and harmful gases produced by the chemical reaction inside the reactor may escape through gaps in the connection towards the feed pipe, ultimately leaking into the working environment.

[0066] Therefore, it is necessary to provide a reactor feed pipe device and operating method that can effectively prevent residual material bridging and has good sealing performance.

[0067] The defects in the above solutions and the reasons for their occurrence are the results of the inventors' practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventors' contributions to this disclosure.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] Reference Appendix Figure 2The 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.

[0072] Reference Appendix Figure 3 An adjusting element 5 is rotatably mounted inside the feeding pipe 3 and is linked with the sealing plate 20. When the two sealing plates 20 move towards each other, the adjusting element 5 is driven to rotate forward, opening the first air hole 32 on the partition pipe 31 to allow dry gas to flow into the partition pipe 31. When the two sealing plates 20 move away from each other, the adjusting element 5 is driven to rotate in the opposite direction, closing the first air hole 32 on the partition pipe 31. The pressure inside the air chamber 30 increases, causing the adjusting element 5 to vibrate relative to the base plate 2. The cooperation between the two sealing plates 20 and the adjusting element 5 solves the technical problems of material residue and "bridging" in the feeding pipe 3. When feeding ends and the two sealing plates 20 move away from each other to close the partition pipe 31, the sealing plates 20 drive the adjusting element 5 to rotate in the opposite direction, closing the first air hole 32. This causes the dry gas input from the air inlet pipe 4 to be sealed within the air chamber 30, resulting in a rapid increase in pressure. The accumulated gas pressure will drive the regulating element 5 to vibrate relative to the base plate 2. This vibration is transmitted to the inside of the feeding pipe 3 through the partition pipe 31, which effectively impacts and shakes off residual materials that may adhere to the pipe wall, especially easily sticky powders, thereby disrupting their "bridging" tendency and ensuring the smoothness of the next feeding.

[0073] Reference Appendix Figure 3The adjusting component 5 includes: an adjusting ring 51, which is rotatably disposed above the sealing plate 20; and an adjusting tube 52, which is vertically disposed on the adjusting ring 51, with its inner wall fitting against the outer wall of the partition tube 31. The inner wall of the adjusting tube 52 and the outer wall of the partition tube 31 are precisely fitted together, allowing for relative sliding while maintaining good airtightness. Several first air holes 32 are evenly distributed circumferentially on the wall of the partition tube 31. Correspondingly, several second air holes 53 are also evenly distributed circumferentially on the wall of the adjusting tube 52, with the number and position of the second air holes 53 corresponding one-to-one with the first air holes 32. When the adjusting ring 51 rotates forward, the adjusting tube 52 rotates relative to the partition tube 31, causing the first air holes 32 and second air holes 53 to completely overlap; when the adjusting ring 51 rotates in the reverse direction, the adjusting tube 52 rotates relative to the partition tube 31, causing the first air holes 32 and second air holes 53 to be misaligned.

[0074] Continue to refer to the appendix Figure 3 To achieve linkage between the sealing plate 20 and the adjusting component 5, a linkage post 21 is fixedly installed on the upper surface of each sealing plate 20. The height of the linkage post 21 is greater than the thickness of the adjusting ring 51. Two sliding grooves 54 are symmetrically formed along the circumference of the adjusting ring 51. The upper end of each linkage post 21 extends into a sliding groove 54. The sliding groove 54 is not a straight groove, but rather an arc. The center of this arc does not coincide with the axis of the adjusting ring 51, so that the distance from one end of the sliding groove 54 to the axis of the adjusting ring 51 gradually increases towards the other end (i.e., it is an eccentric arc groove).

[0075] 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.

[0076] 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.

[0077] Reference Appendix Figure 3A 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.

[0078] 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.

[0079] At least one embodiment provides a method for operating a reactor feed pipe device, the method comprising:

[0080] 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.

[0081] 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.

[0082] The working principle of the feed pipe 3 device in reactor 1 is as follows:

[0083] 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.

[0084] 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.

[0085] like Figure 3 As 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).

[0086] 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).

[0087] 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.

[0088] 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.
