Description

Technical Field

[0001] The present application relates to the technical field of acetylene production, and in particular to an acetylene generator. Background Art

[0002] An acetylene generator is a device used to produce acetylene gas by chemically reacting water and calcium carbide (CaC2). The main acetylene production processes include hydrocarbon cracking and the calcium carbide process. The calcium carbide acetylene process can be categorized as either a wet process or a dry process, depending on the heat removal method and water addition method. The dry process involves spraying water into calcium carbide to produce acetylene, and is currently the primary method for producing acetylene gas.

[0003] The existing generator is provided with a stirring device and a multi-stage reaction plate. The reaction plate is provided with a feed port. The multi-stage reaction plates are horizontally arranged at equal intervals in the generator. The stirring device is provided with rake teeth. After the material enters the generator, it falls onto the reaction plate. Water is sprayed on the material through the spray valve on the upper part of the generator, and the material on the reaction plate is stirred by the rake teeth provided on the stirring device, so that the calcium carbide undergoes a hydrolysis reaction to produce acetylene gas.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the rake teeth on the stirring device stir the calcium carbide, so that the calcium carbide and water mix and react quickly, but a large amount of reacted calcium carbide slag on the reaction plate sticks together to form lumps after encountering water, causing the calcium carbide and calcium carbide slag to accumulate on the reaction plate, resulting in the unreacted calcium carbide being unable to react with water better, affecting the production of acetylene. Summary of the Invention

[0005] The purpose of this application is to provide an acetylene generator to improve the problem that a large amount of carbide slag after reaction on the reaction plate sticks together to form lumps when it comes into contact with water, causing the accumulation of carbide and carbide slag on the reaction plate, resulting in the unreacted carbide being unable to react with water better, thereby affecting the production of acetylene.

[0006] The acetylene generator provided in this application adopts the following technical solution: An acetylene generator comprises a cylinder body and a feed pipe and an air outlet pipe sealed with the top of the cylinder body, a slag discharge pipe is provided at the bottom of the cylinder body, a placement plate for receiving calcium carbide is provided in the cylinder body, a flipping assembly is rotatably provided in the cylinder body, a water supply pipeline facing the placement plate is provided in the cylinder body, the placement plate comprises a reaction plate 1 fixedly connected to the inner wall of the cylinder body and a reaction plate 2 fixedly connected to the rotating shaft, a rotating shaft corresponding to the flipping assembly is rotatably provided in the cylinder body, a grille plate is fixedly provided above the reaction plate 1, a plurality of reaction grids are provided in the grille plate, a flip plate that fits the upper surface of the reaction plate 1 is provided at the bottom of the grille plate facing the rotation direction of the rotating shaft, a driving motor for driving the rotating shaft is provided on the outside of the cylinder body, and a discharge port 1 is provided at the center axis position of the reaction plate 1.

[0007] By adopting the above technical solution, the water supply pipeline sprays water toward the placement plate, and the reaction grid of the grille plate divides the placed calcium carbide into zones to ensure a uniform reaction area between water and calcium carbide. The flip plate fits with the upper surface of the reaction plate as the grille plate rotates, and can continuously flip the calcium carbide material to avoid agglomeration of calcium carbide after reaction and promote the full hydrolysis reaction. The discharge port is located at the central axis position of the reaction plate, which facilitates the downward discharge of calcium carbide slag after the reaction, reduces the accumulation of residue on the reaction plate, and allows the unreacted calcium carbide to continue to react with water to reduce the impact on acetylene production. Optionally, a fixing rod is provided on the inner wall of the cylinder toward the grille plate, a partition plate is extended above the grille plate, the partition plate is inclined toward one side of the reaction grid, a rake plate is provided on the top of the fixing rod to fit the partition plate, a plurality of sieve holes are provided in the reaction plate, and a plurality of scrapers are provided on the flip surface of the flip plate.

[0008] By adopting the above technical solution, the fixed rod and the partition plate cooperate to form an inclined guide structure above the grille plate, and the calcium carbide gathers toward the reaction grid along the partition plate. When the grille plate rotates, the rake plate on the fixed rod will move the part of the calcium carbide above the partition plate to the adjacent reaction grid, preventing excessive accumulation of material in a certain reaction grid and affecting the hydrolysis reaction rate of calcium carbide; the scraper on the flipping plate shovels the calcium carbide material that is partially stuck to the surface of the reaction disk during rotation, removes the attached residue, and pushes the flipped and crushed calcium carbide slag to the sieve hole one and falls down, so that part of the calcium carbide material falls from the discharge port one to the reaction disk two to continue reacting.

[0009] Optionally, a bevel groove is provided on the upper surface of the reaction disk, the flip plate fits into the bevel groove, the flip plate is arranged in an arc shape along the radial direction of the reaction disk, one end of the flip plate faces the discharge port 1, and the rotating shaft is located at the discharge port 1 and is fixedly connected to a spiral blade.

[0010] By adopting the above-mentioned technical solution, the inclined groove on the reaction disk 1 fits with the flip plate, and the flip plate is arc-shaped along the radial direction, so that the flip plate can completely cover the surface of the reaction disk 1 when rotating, clean up the residue and push the material to move toward the center discharge port 1; the spiral blades arranged on the rotating shaft at the discharge port 1 can spirally transport some of the larger accumulated calcium carbide slag and some calcium carbide materials to the lower area to prevent the discharge port 1 from being blocked, and at the same time the spiral blades block the unreacted calcium carbide on the reaction disk 1.

[0011] Optionally, a flexible screen for filtering carbide slag is provided below the reaction disk, a fixed plate for fixing the edge position of the flexible screen is provided at the bottom of the reaction disk, and a rotating seat rotatably connected to the rotating shaft is provided at the center of the flexible screen.

[0012] By adopting the above technical solution, the flexible screen arranged under the reaction disk one is fixed at the edge by a fixed plate, and the center is connected to the rotating seat of the rotating shaft. The flexible screen can filter the fallen calcium carbide material, so that the calcium carbide slag after the reaction falls through the mesh holes of the flexible screen, and the calcium carbide material and the calcium carbide slag are separated, preventing the calcium carbide material and the calcium carbide slag from falling on the reaction disk two together and causing blockage.

[0013] Optionally, the water supply pipeline includes a water spray pipe 1 located above the reaction disk 1 and a water inlet pipe passing through the side wall of the cylinder, and the water inlet pipe is provided with a water spray pipe 2 extending toward the bottom of the flexible screen. The water spray pipe 1 and the water spray pipe 2 are both arranged in a ring shape, and a plurality of nozzles are provided on the water spray pipe 1 toward the direction of the reaction disk 1 and the water spray pipe 2 toward the flexible screen.

[0014] By adopting the above technical solution, water spray pipe one is located above reaction disk one, with the nozzle facing reaction disk one, which can evenly wet the calcium carbide material and control the hydrolysis reaction rate; water spray pipe two extends to the bottom of the flexible screen, with the nozzle facing the screen, and reversely flushes the screen during the filtration process to prevent fine particles from clogging the mesh holes. At the same time, part of the calcium carbide material in the flexible screen continues to undergo hydrolysis reaction to generate acetylene, thereby increasing the reaction rate.

[0015] Optionally, a reciprocating thread segment is provided at one end of the rotating shaft below the reaction disk, the rotating seat is threadedly connected to the reciprocating thread segment, and when the rotating seat moves to the top of the reciprocating thread segment, the flexible screen is located between the rotating seat and the fixed plate in a concave shape.

[0016] By adopting the above technical solution, the reciprocating thread section below the rotating shaft is threadedly connected to the rotating seat. When the rotating shaft rotates, the rotating seat moves up and down along the reciprocating thread section, driving the flexible screen to produce periodic concave deformation. When the rotating seat moves to the top of the thread section, the screen is concave, and the elastic deformation of the flexible material is used to stretch and vibrate the screen, effectively removing particulate impurities attached to the screen, and at the same time allowing the calcium carbide material and calcium carbide slag on the flexible screen to be fully screened and filtered.

[0017] Optionally, the water spray pipe 2 is provided with several branch pipes extending toward the direction of the rotating axis, and the nozzles are also arranged on the concave surface of the end of the branch pipe facing the flexible screen away from the water spray pipe 2. The nozzles of the water spray pipe 2 and the branch pipe 2 are both inclined toward the flexible screen.

[0018] By adopting the above technical solution, the branch pipe of the second water spray pipe extends toward the rotating shaft, and the nozzle is tilted toward the concave surface of the flexible screen, and high-pressure flushing is performed on the back of the screen when the screen is concave; the inclined nozzle can form a multi-angle impact force, and the branch pipe expands the flushing range of the screen, while further accelerating the hydrolysis reaction rate of the calcium carbide material in the flexible screen.

[0019] Optionally, the rotating shaft is located at the top of the reciprocating threaded section and is fixedly connected to an umbrella-shaped cover covering the rotating seat. A knocking rod is rotatably arranged inside the umbrella-shaped cover and is directed toward the flexible screen. Inclined plates corresponding to the knocking rod are arranged at intervals on the edge of the rotating seat. When the umbrella-shaped cover rotates, the knocking rod moves to a higher place along the inclined surface of the inclined plate and knocks on the flexible screen.

[0020] By adopting the above technical solution, the umbrella-shaped cover covers the rotating seat to prevent the material falling from the discharge port from falling to the threaded connection between the reciprocating thread section and the rotating seat and causing an impact. A knocking rod is arranged in the umbrella-shaped cover on the rotating shaft. During the rotation of the rotating shaft, the knocking rod rises along the inclined surface of the inclined plate on the rotating seat. After separating from the inclined plate, the knocking rod falls back under the action of gravity, generating a knocking force on the flexible screen, causing the flexible screen to vibrate, further removing particulate impurities attached to the screen, and preventing the mesh of the flexible screen from being clogged.

[0021] Optionally, a plurality of discharge openings 2 are opened in the rotating seat along its circumferential direction, and the larger calcium carbide slag slides toward the discharge opening 2 along the inclined flexible screen when the rotating seat moves to the bottom end of the reciprocating thread section.

[0022] By adopting the above technical solution, the second discharge port in the circumferential direction of the rotating seat cooperates with the flexible screen that becomes inclined after the rotating seat moves. When the rotating seat moves to the bottom end of the reciprocating thread section, the screen becomes inclined, and the larger calcium carbide slag slides along the inclined surface of the screen under the action of gravity to the second discharge port and is directly discharged from the flexible screen, preventing the larger material in the flexible screen from clogging the screen.

[0023] Optionally, the reaction disk 2 is tilted toward the edge, a sieve hole 2 is provided in the reaction disk 2, the diameter of the sieve hole 2 is smaller than the diameter of the sieve hole 1, part of the nozzles on the water spray pipe 2 are tilted toward the reaction disk 2, and a lever corresponding to the upper surface of the reaction disk 2 is provided on the inner wall of the cylinder above the reaction disk 2.

[0024] By adopting the above technical solution, the reaction disk 2 is designed to be inclined toward the edge, and the sieve hole 2 allows larger calcium carbide material particles to remain on the surface of the reaction disk 2 to continue reacting, and fine calcium carbide slag particles fall through the sieve hole 2, preventing incompletely reacted calcium carbide particles from entering the slag discharge system prematurely. The inclined disk surface allows the material to naturally move toward the edge and fall during the rotation of the reaction disk 2. The lever on the inner wall of the cylinder continuously moves the material on the surface of the reaction disk 2 to prevent the material from sticking or clumping; the nozzle of the second part of the water spray pipe sprays water at an angle toward the reaction disk 2, which can carry out directionally flushing of the surface of the reaction disk 2, promptly remove attached residues and replenish the water required for the reaction, thereby improving the material processing efficiency of the reaction disk 2 and ensuring the continuity and sufficiency of the acetylene generation process.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The water supply pipeline sprays water toward the placement tray, and the reaction grid of the grid tray divides the added calcium carbide into zones to ensure a uniform reaction area between water and calcium carbide. The flip plate fits with the upper surface of the reaction tray as the grid tray rotates, which can continuously flip the calcium carbide material, avoid calcium carbide agglomeration and promote the full hydrolysis reaction. The discharge port is located at the central axis of the reaction tray, which facilitates the downward discharge of calcium carbide slag after the reaction, reduces the accumulation of residue on the reaction tray, and allows the unreacted calcium carbide to continue to react with water, minimizing the impact on acetylene production. 2. The reciprocating thread section below the rotating shaft is threadedly connected to the rotating seat. When the rotating shaft rotates, the rotating seat moves up and down along the reciprocating thread section, driving the flexible screen to produce periodic concave deformation. When the rotating seat moves to the top of the thread section, the screen is concave. The elastic deformation of the flexible material is used to stretch and vibrate the screen, effectively removing particulate impurities attached to the screen, while fully screening and filtering the calcium carbide materials and calcium carbide slag on the Rosse flexible screen. 3. The umbrella-shaped cover covers the rotating seat to prevent the material falling from the discharge port from dripping and affecting the threaded connection between the reciprocating thread section and the rotating seat. A knocking rod is set in the umbrella-shaped cover on the rotating shaft. During the rotation of the rotating shaft, the knocking rod rises along the inclined surface of the inclined plate on the rotating seat. After leaving the inclined plate, the knocking rod falls back under the action of gravity, generating a knocking force on the flexible screen, causing the flexible screen to vibrate, further removing particulate impurities attached to the screen, and preventing the mesh of the flexible screen from being blocked.
