Description

Technical Field

[0001] This invention belongs to the field of powder material feeding technology, specifically relating to a reaction vessel feeding device to prevent powder materials from agglomerating. Background Technology

[0002] In the petrochemical industry, it is often necessary to add powdered materials into reaction vessels containing liquids. When powdered materials are added to the surface of the liquid in the reaction vessel, agglomeration is likely to occur, meaning that the powdered materials clump together and float to the surface of the liquid.

[0003] To ensure thorough mixing of powdered materials with liquid, a feeding tube is typically inserted into the liquid within the reactor. The powdered material moves along the feeding tube to the feeding port (located below the liquid surface) and mixes with the liquid there. However, upon contact with the liquid, some of the powdered material quickly clumps together and adheres to the feeding port of the feeding tube. Over time, this can even block the feeding port, preventing the fully metered powdered material from entering the reactor and mixing with the liquid. This negatively impacts the final product quality and may even lead to product spoilage. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a reactor feeding device to prevent powder material agglomeration. The feeding pipe extends below the liquid surface to feed powder into the liquid, ensuring thorough mixing between the powder and the liquid within the reactor. An air inlet pipe is installed on the side of the feeding pipe, through which high-pressure gas is intermittently supplied to blow away any agglomerated powder adhering to the feeding port. A spiked bar is installed in the lower pipe to stir and disperse any agglomerated powder, suppressing agglomeration and ensuring thorough mixing between the powder and liquid, thereby guaranteeing product quality.

[0005] This invention is achieved through the following technical solution:

[0006] A reactor feeding device for preventing powder material agglomeration includes a feeding pipe, a drive unit, an air inlet pipe, and a spiral blade. Two feeding pipes are arranged side-by-side and interconnected. Each feeding pipe includes an upper pipe and a lower pipe. A drive shaft and a spiral blade fixed to the drive shaft are installed in each upper pipe. The feeding port at the bottom of the lower pipe extends below the liquid surface in the reactor to feed the powder into the liquid. The drive unit includes a motor and a reducer. The motor drives the drive shaft to rotate via the reducer. The air inlet pipe is inclined downwards and connects to the bottom of the upper pipe. A high-pressure air pump is installed at the air inlet of the air inlet pipe. The high-pressure air pump can intermittently deliver high-pressure gas into the feeding pipe to blow away agglomerated powder in the lower pipe. The spiked bar is located in the lower tube and fixed to the bottom of the drive shaft. The spiked bar is coaxial with the drive shaft. Several stirring protrusions protrude from the outside of the spiked bar. Each stirring protrusion is arranged in a spiral shape and is in the same direction as the spiral blade. A mixing gap is formed between adjacent stirring protrusions to ensure that the powder and liquid are fully mixed and to facilitate the passage of high-pressure gas through the mixing gap to blow the agglomerated material into the liquid.

[0007] Furthermore, the spiked rods consist of a first rod and a second rod. A propeller is mounted at the bottom of the first rod, with its shaft fixed to the bottom and coaxial with the first rod. When the propeller rotates, it provides a driving force that propels the liquid vertically downwards. Alternatively, a propeller is mounted at the bottom of the second rod, with its shaft fixed to the bottom and coaxial with the second rod. When the propeller rotates, it provides a driving force that propels the liquid vertically downwards. By placing a propeller below the spiked rods, the rotation of the propeller causes the liquid above it to flow vertically downwards, reducing the pressure of the liquid on the powder at the feeding port and facilitating the feeding of the powder into the liquid along the feeding pipe.

[0008] Furthermore, the reactor feeding device also includes a support base, which is fixed to the bottom of the reactor. A support bearing is installed on the support base and attached to the bottom end of the rotating shaft. The support base supports the rotating shaft through the support bearing, thereby supporting the entire feeding pipe.

[0009] Furthermore, a conical baffle is provided at the bottom of the lower tube body. The conical baffle is fitted onto the outer wall of the lower tube body, and its opening gradually widens along the vertical downward direction. The conical baffle works in conjunction with the propeller, preventing the liquid above the baffle from flowing towards the propeller. This helps reduce the pressure of the liquid below the baffle on the feed inlet, facilitating the feeding of powder into the liquid at the feed inlet.

[0010] Furthermore, the inner wall of the feeding pipe, the drive shaft, the spiral blade, and the outer side of the spiked rod are all coated with Teflon, thereby reducing the coefficient of friction on the surfaces of the feeding pipe, the drive shaft, the spiral blade, and the spiked rod, and inhibiting the adhesion and agglomeration of powder.

[0011] Furthermore, the reactor feeding device also includes a support plate, which is fixed to the bottom of the lower tube by a fixing rod. The bottom ends of the two spiked rods are fixed to the support plate by bearings, which improves the rotational stability of the two spiked rods and the drive shaft.

[0012] Furthermore, a vibrating motor is also fitted at the bottom of the lower pipe body. The vibrating motor is ring-shaped and its bottom surface is flush with the bottom surface of the lower pipe body, so as to achieve vibration cleaning of the bottom of the lower pipe body and to separate the agglomerated powder.

[0013] Furthermore, the upper and lower pipe bodies are connected by flanges, and a sealing gasket is installed between them. The upper and lower pipe bodies are connected by detachable flanges, which facilitates regular comprehensive cleaning or maintenance of the lower pipe body.

[0014] Furthermore, the spiked rod protrudes downwards from the lower tube body. Let the length of the spiked rod be h, and the length of the lower tube body be H, then 1 / 5H < h < H. The downward protrusion of the spiked rod effectively prevents large-area clumping of powder at the feeding port.

[0015] Furthermore, a heating jacket is fixed at the lower part of the lower tube body. The heating jacket is fitted onto the outer wall of the lower tube body and is waterproof, connected to the outside of the reactor via a waterproof cable. Heating the powder and liquid at the feeding port accelerates the reaction rate of the powder dissolving into the liquid, thereby inhibiting agglomeration.

[0016] The beneficial effects of this invention are:

[0017] 1. The feeding pipe extends below the liquid surface to feed the powder into the liquid, so that the powder can be fully mixed with the liquid in the reactor;

[0018] 2. By setting an air inlet pipe on the side of the feeding pipe, high-pressure gas is intermittently transported through the air inlet pipe to blow away the powder adhering to the feeding port, so as to facilitate the powder being added to the liquid.

[0019] 3. A spiked bar is installed in the lower pipe to stir and break up clumps of powder material, suppressing the clumping phenomenon and ensuring thorough mixing of powder and liquid to guarantee product quality. Attached Figure Description

[0032] Finally, it should be noted that when a component is said to be "located on" or "set on" another component, it can be on the other component or may have an intervening component at the same time. When a component is said to be "connected to" another component, it can be directly connected to the other component or may have an intervening component at the same time.

[0033] like Figures 1 to 7 A reactor feeding device for preventing powder material agglomeration is shown, comprising a feeding pipe 1, a drive unit 2, an air inlet pipe 3, and a spiral blade 4. Two feeding pipes 1 are arranged side-by-side and interconnected. Each feeding pipe 1 includes an upper pipe body 11 and a lower pipe body 12. Each upper pipe body 11 is equipped with a drive shaft 13 and a spiral blade 14 fixed to the drive shaft 13. The feeding port 15 at the bottom of the lower pipe body 12 extends below the liquid surface in the reactor to feed powder into the liquid. The drive unit 2 includes a motor 21 and a reducer 22. The motor 21 drives the drive shaft 13 to rotate via the reducer 22. The air inlet pipe 3 is inclined downwards and connects to the bottom of the upper pipe body 11. A high-pressure air pump is installed at the air inlet of the air inlet pipe 3. The high-pressure air pump can intermittently deliver high-pressure gas into the feeding pipe 1 to blow away agglomerated powder in the lower pipe body 12. The spiked bar 4 is located on the lower tube 12 and fixed to the bottom end of the drive shaft 13. The spiked bar 4 is coaxially arranged with the drive shaft 13. Several stirring protrusions 41 protrude from the outside of the spiked bar 4. Each stirring protrusion 41 is arranged in a spiral shape and is consistent with the rotation direction of the spiral blade 14. A mixing gap 42 is formed between adjacent stirring protrusions 41 to ensure that the powder and liquid are fully mixed and to facilitate the passage of high-pressure gas through the mixing gap 42 to blow the agglomerated material into the liquid.

[0034] In one embodiment, before installing the reactor feeding device, the liquid inside the reactor needs to be drained, and then the reactor feeding device can be installed. For example... Figure 2 As shown, the reactor feeding device needs to be installed vertically inside the reactor, with the drive unit 2 of the feeding device fixed above the reactor. After installation, the liquid to be treated is injected into the reactor, ensuring that the liquid covers the feeding port 15 at the bottom of the feeding pipe 1. It should be noted that the reactor is a closed container with a small vent. The top of the feeding pipe 1 is equipped with a feed inlet to facilitate the feeding of powdered materials into the reactor.

[0035] In one embodiment, when using the reactor feeding device, firstly, the motor 21 is turned on. The motor 21 drives the drive shaft 13 to rotate through the reducer 22, which in turn drives the spiral blade 14 to rotate. Since the spiked rod 4 is fixed to the bottom of the drive shaft 13, the spiked rod 4 rotates synchronously with the drive shaft 13. Then, powder material is continuously fed into the upper feed port of the feeding pipe 1. The powder material gradually moves vertically downward in the upper pipe 11 under the drive of the spiral blade 14 until the powder material enters the lower pipe 12. Since the spiked rod 4 rotates synchronously with the drive shaft 13, and the stirring protrusions 41 on the spiked rod 4 are spirally distributed, the powder material continues to move downward under the force of gravity and the push of the spirally distributed stirring protrusions 41 until the powder material is discharged at the feeding port 15. Since the feeding port 15 is located below the liquid surface, the powder material reacts with the liquid immediately upon discharge from the feeding port 15, so that the powder material can be mixed evenly with the liquid, preventing the powder material from floating to the surface of the liquid and affecting the reaction with the liquid. The use of spiral blades 14 and spirally distributed stirring protrusions 41 promotes the downward movement of powder materials into the liquid in the reactor. Compared with direct feeding through pipes, the rotation of the spiral blades 14 and stirring protrusions 41 effectively inhibits large-area agglomeration of powder materials, effectively preventing powder materials from clogging the feed inlet 15. The use of two parallel and interconnected feed pipes 1 improves feeding efficiency, and it is difficult for powder materials to simultaneously agglomerate and clog within both feed pipes 1, effectively ensuring the reaction between the powder materials and the liquid.

[0036] In one embodiment, since the feed port 15 is located below the liquid surface, that is, part of the lower tube 12 extends below the liquid surface. The liquid in the reactor will immerse into the lower tube 12 through the feed port 15. When the powder and liquid are mixed in the lower tube 12 immersed in the liquid, agglomeration is likely to occur. In order to ensure that the powder and liquid are fully mixed, stirring protrusions 41 are provided on the spike rod 4. The stirring protrusions 41 can stir the powder in the lower tube 12 and prevent the powder from agglomerating and clogging the lower tube 12.

[0037] In one embodiment, when local agglomeration of the powder material occurs, i.e., when agglomeration occurs at the mixing gap 42 between adjacent stirring protrusions 41, a high-pressure air pump is started. The high-pressure air pump inputs high-pressure gas into the air inlet pipe 3. Since the air pipe is inclined towards the lower pipe 12, most of the high-pressure gas is filled into the lower pipe 12. The high-pressure gas impacts the mixing gap 42 between adjacent stirring protrusions 41 to blow away the powder material attached to the mixing gap 42 and promotes the vertical downward conveying of the powder material into the liquid.

[0038] In one embodiment, the high-pressure air pump is started intermittently. That is, when the high-pressure gas is input into the air inlet pipe 3, it vibrates. In layman's terms, when the high-pressure gas impacts the powder material, it will make a "boom, boom, boom" sound. The high-pressure gas input into the air inlet pipe 3 in a vibrating manner has a vibration effect on the powder material, which helps the powder material adhering to the spike rod 4 or the inner wall of the lower pipe 12 to continue to move vertically downward and be discharged to the feeding port 15.

[0039] Preferably, the spiked rods 4 are a first rod 43 and a second rod 44. A propeller 5 is installed at the bottom of the first rod 43, and the shaft 51 of the propeller 5 is fixed to the bottom end of the first rod 43 and coaxially arranged with the first rod 43. When the propeller 5 rotates, it has a driving force to drive the liquid to flow vertically downward. Alternatively, a propeller 5 is installed at the bottom of the second rod 44, and the shaft 51 of the propeller 5 is fixed to the bottom end of the second rod 44 and coaxially arranged with the second rod 44. When the propeller 5 rotates, it has a driving force to drive the liquid to flow vertically downward. By setting the propeller 5 below the spiked rods 4, the rotation of the propeller 5 causes the liquid above the propeller 5 to flow vertically downward, reducing the pressure of the liquid on the powder at the feeding port 15, and facilitating the feeding of the powder into the liquid along the feeding pipe 1.

[0040] In one embodiment, two spiked clubs 4 are provided, and a propeller 5 is installed at the bottom of one of the spiked clubs 4. Figure 6 and Figure 7 As shown, a propeller 5 is installed at the bottom of the first rod 43. It should be noted that the propeller 5's shaft 51, the spiked rod 4, and the drive shaft 13 are all coaxially arranged and fixed together. That is, the motor 21 synchronously drives the integrated drive shaft 13, spiked rod 4, and shaft 51 to rotate via the reducer 22. The shaft 51 drives the propeller 5 to rotate, causing the liquid above the propeller 5 to tend to flow downwards. The downward flow of the liquid above the propeller 5 reduces the liquid pressure above the propeller 5, that is, reduces the pressure of the liquid on the feed port 15, which helps the powder material to be discharged downwards at the feed port 15.

[0041] Preferably, the reactor feeding device further includes a support base 6, which is fixed to the bottom of the reactor. A support bearing 61 is installed on the support base 6 and is mounted to the bottom end of the rotating shaft 51. The support base 6 supports the rotating shaft 51 through the support bearing 61, thereby supporting the entire feeding pipe 1.

[0042] In one embodiment, a support base 6 is installed at the bottom of the reactor, and the bottom of the rotating shaft 51 is mounted to the support base 6 via a support bearing 61. That is, the support base 6 provides support for the rotating shaft 51, the spiked club 4, and the drive shaft 13, forming an upward support for the reactor feeding device, thereby improving the stability of the reactor feeding device.

[0043] Preferably, a conical baffle 7 is provided at the bottom of the lower pipe body 12. The conical baffle 7 is sleeved onto the outer wall of the lower pipe body 12, and the opening of the conical baffle 7 gradually increases in the vertical downward direction. The conical baffle 7 is used in conjunction with the propeller 5. The conical baffle 7 can prevent the liquid above the conical baffle 7 from flowing towards the propeller 5, which helps to reduce the pressure of the liquid below the conical baffle 7 on the feed port 15, making it easier for the powder to be fed into the liquid at the feed port 15.

[0044] In one embodiment, the conical baffle 7 is a downward-opening cone, which can prevent liquid above the conical baffle 7 from flowing into the space below the conical baffle 7, thus contributing to a drop in liquid pressure at the feed port 15. This, in turn, facilitates the outflow of powder material from the feed port 15. It should be noted that although the propeller 5 has a downward driving effect on the liquid, since the feed port 15 extends below the liquid surface, it will still be rapidly filled with liquid. The propeller 5 can reduce the pressure of the liquid on the feed port 15. It should also be noted that the lower tube 12 is partially wetted with liquid. When the propeller 5 is started, the liquid in the lower tube 12, mixed with powder material, tends to move downward, which helps the powder material flow downward out of the feed port 15.

[0045] Preferably, the inner wall of the feeding pipe 1, the drive shaft 13, the spiral blade 14, and the outer side of the spiked rod 4 are all coated with Teflon coating, thereby reducing the coefficient of friction of the surfaces of the feeding pipe 1, the drive shaft 13, the spiral blade 14, and the spiked rod 4, and inhibiting the adhesion and agglomeration of powder.

[0046] It should be noted that Teflon, also known as polytetrafluoroethylene, is generally referred to as a "non-stick coating" or "easy-clean wok material." It is a synthetic polymer material in which fluorine replaces all the hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE is heat-resistant and has an extremely low coefficient of friction, making it suitable for lubrication and as an ideal coating for easy-clean woks and the inner lining of water pipes. Therefore, spraying a Teflon coating on the inner wall of the feeding pipe 1, the drive shaft 13, the spiral blade 14, and the outer side of the spiked rod 4 effectively reduces the adhesion of powder materials.

[0047] Preferably, the reactor feeding device further includes a support plate 16, which is fixed to the bottom of the lower tube 12 by a fixing rod 17. The bottom ends of the two spikes 4 are fixed to the support plate 16 by bearings, which improves the rotational stability of the two spikes 4 and the drive shaft 13.

[0048] In one embodiment, the support plate 16 is fixed to the bottom of the feeding pipe 1 by the fixing rod 17, and the bottom of the two spikes 4 are both mounted to the support plate 16 by bearings. The spikes 4 and the drive shaft 13 are coaxially arranged and fixed to each other. The top of the drive shaft 13 is mounted to the reducer 22, and the bottom of the spikes 4 is mounted to the support plate 16, thereby limiting and fixing both ends of the shaft composed of the drive shaft 13 and the spikes 4, and improving the rotational stability of the drive shaft 13 and the spikes 4.

[0049] Preferably, a vibration motor 8 is also sleeved at the lower part of the lower pipe body 12. The vibration motor 8 is ring-shaped and the bottom surface of the vibration motor 8 is flush with the bottom surface of the lower pipe body 12, so as to realize the vibration cleaning of the bottom of the lower pipe body 12 and the separation of agglomerated powder.

[0050] In one embodiment, the section of the lower pipe 12 extending below the liquid surface is a significant area where powder agglomeration occurs. To prevent powder agglomeration in this area from clogging the lower pipe 12, a vibrating motor 8 is fitted below the lower pipe 12. The vibrating motor 8 vibrates to suppress powder agglomeration at the feed inlet 15 of the feed pipe, thus preventing clogging of the lower pipe 12. It should be noted that the power cord arrangement and vibration principle of the vibrating motor 8 are conventional technologies and will not be described in detail here.

[0051] Preferably, the upper pipe body 11 and the lower pipe body 12 are connected by a flange 18, and a sealing gasket is installed between the upper pipe body 11 and the lower pipe body 12. The upper pipe body 11 and the lower pipe body 12 are connected by a detachable flange 18, which facilitates regular comprehensive cleaning or maintenance of the lower pipe body 12.

[0052] In one embodiment, the lower tube 12 is prone to damage due to prolonged immersion in liquid, which is typically corrosive. Furthermore, the continuous transport of powder materials leads to the accumulation of difficult-to-clean powder within the lower tube 12. The lower tube 12 is designed to be detachable from the upper tube 11. The lower tube 12 can be removed by disassembling the flange 18, facilitating thorough cleaning or replacement / repair of the lower tube 12.

[0053] Preferably, the spiked rod 4 protrudes downwards from the lower tube 12. Let the length of the spiked rod 4 be h, and the length of the lower tube 12 be H, then 1 / 5H < h < H. The downward protrusion of the spiked rod 4 from the lower tube 12 effectively prevents large-area agglomeration of powder at the feeding port 15.

[0054] In one embodiment, the spiked rod 4 protrudes downwards and into the feed port 15 of the lower tube 12, meaning that the part of the spiked rod 4 protruding from the lower tube 12 is in direct contact with the liquid. This design, compared to designing the spiked rod 4 and the lower tube 12 to be of equal length, can more effectively prevent the powder material from caking and blocking the feed port 15.

[0055] Preferably, a heating sleeve 9 is also fixed below the lower tube 12. The heating sleeve 9 is fitted onto the outer wall of the lower tube 12, and is waterproof and connected to the outside of the reactor via a waterproof cable. The powder and liquid at the feeding port 15 are heated to accelerate the reaction rate of the powder dissolving into the liquid, thereby inhibiting the occurrence of agglomeration.

[0056] In one embodiment, under normal conditions, the higher the temperature, the faster the reaction rate between the powder and the liquid. To improve the reaction rate between the powder and the liquid, a heating jacket 9 is installed at the feeding port 15 of the lower pipe 12. The heating jacket 9 heats the liquid and powder at the feeding port 15, accelerating the dissolution rate of the powder in the liquid, thereby inhibiting the agglomeration of the powder to a certain extent.

[0057] When using the above-mentioned reactor feeding device for preventing powder agglomeration, the feeding pipe 1 extends below the liquid surface to feed the powder into the liquid, allowing the powder to mix thoroughly with the liquid in the reactor. An air inlet pipe 3 is installed on the side of the feeding pipe 1, through which high-pressure gas is intermittently delivered to blow away any agglomerated powder adhering to the feeding port 15. A spiked bar 4 is installed in the lower pipe body 12 to stir and disperse the agglomerated powder, suppressing agglomeration and ensuring thorough mixing between the powder and liquid, thus guaranteeing product quality.

[0058] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
