Technical Field

[0001] The invention relates to the technical field of acetylene production, in particular to a continuous feeding device for an acetylene production cracking furnace. Background Art

[0002] When cracking organic matter in the chemical industry, how to send the screened and crushed raw materials into the cracking furnace for cracking is a key technology related to efficiency and safety.

[0003] During the acetylene production process, in order to maintain the output, the acetylene raw material is generally continuously fed into the cracking furnace through a feed pipe during the reaction inside the cracking furnace. However, the temperature inside the cracking furnace is relatively high, and both acetylene and the raw material are flammable. Therefore, during the feeding process, the acetylene and high temperature inside the cracking furnace will be transmitted to the inside of the acetylene raw material box through the feed pipe. Therefore, it is easy for the high temperature to cause accidents such as fire, resulting in low safety of the device. Summary of the invention

[0018] The present invention has the following beneficial effects:

[0019] During feeding, the inlet is connected to the material storage mechanism through a hose, and the material enters the feed box through the connection between the interface mechanism and the injection port, so that the feed box is filled with the material, and the hydraulic cylinder is started to drive the connection frame to descend through the connection plate, thereby driving the limit frame to descend, so that the feed box slides inside the piston cylinder, and while the feed box slides, the injection port is kept away from the telescopic box, and the material outlet of the telescopic box is blocked through the outer wall of the feed box, so that the outlet is separated from the piston cylinder and enters the cracking furnace through the inlet, and the outlet is leaked inside the cracking furnace, so that the material inside the feed box can fall into the cracking furnace through the outlet, and the inside of the cracking furnace is fed back and forth, so that the acetylene and high temperature inside the cracking furnace are prevented from being transmitted to the inside of the material storage mechanism through the feed pipe during the feeding process, thereby reducing the occurrence of accidents such as fire caused by high temperature, thereby improving the safety of the device.

When the injection port corresponds to the feed port of the telescopic box, the telescopic tube enters the feed box through the elastic force of the spring, which is convenient for the raw materials to be injected into the feed box, and the length of the telescopic tube extending into the feed box is limited by the limiting piston, so that when the feed box descends, the arc-shaped opening of the telescopic tube is squeezed to retract the telescopic tube into the telescopic box, thereby increasing the practicality of the device.

[0021] When the hydraulic cylinder drives the feeding mechanism to descend, the connecting rod drives the lifting rod and the rotating rod to descend synchronously. When the rotating rod descends, the rotating rod slides backward inside the movable frame, thereby reducing the inclination angle of the placement plate, the movable plate and the cracking furnace, and making the angle between the movable plate and the cracking furnace vertical, thereby driving the storage box on the top of the placement plate to be horizontal, and through the inclined surface of the storage box, the material inside the storage box flows to the rear of the storage box, so that when the feed box feeds into the cracking furnace, the material inside the storage box stops being transmitted to the inside of the access port through the discharging rack, thereby reducing the pressure at the connection between the access port and the discharging rack, thereby avoiding continuous transmission of the material into the piston cylinder, and reducing the phenomenon of material leakage.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the feed box 602 slides, the injection port 603 is moved away from the telescopic box 206, and the material outlet of the telescopic box 206 is blocked by the outer wall of the feed box 602, so that the outlet 604 is separated from the piston cylinder 205. After the material is sent to the inside of the cracking furnace 201, the feed box 602 is driven to reset, so that the limit sealing plate at the bottom of the feed box 602 abuts against the sealing groove 204, thereby preventing the sealing groove 204 from being separated from the feed port 203, and at the same time, the injection port 603 corresponds to the feed port of the telescopic box 206.

When the hydraulic cylinder 301 drives the feeding mechanism 6 to descend, the connecting rod 304 drives the lifting rod 401 and the rotating rod 402 to descend synchronously. When the rotating rod 402 descends, the rotating rod 402 will be moved in the movable The movable frame 405 slides backward inside, thereby reducing the inclination angle of the placement plate 404, the movable plate 403 and the cracking furnace 201, and making the angle between the movable plate 403 and the cracking furnace 201 vertical, thereby driving the storage box 501 on the top of the placement plate 404 to be horizontal, and through the inclined surface of the storage box 501, the material inside the storage box 501 flows to the rear of the storage box 501, so that when the feed box 602 feeds into the cracking furnace 201, the material inside the storage box 501 stops being transmitted to the inside of the access port 207 through the discharge rack 504, thereby reducing the pressure at the connection between the access port 207 and the discharge rack 504.
