[0002] Automated manufacturing is an important milestone in the development of modern industry. It marks the transformation of manufacturing industry from relying on manual operation to highly automated and intelligent production mode. This transformation not only greatly improves production efficiency, but also significantly reduces costs and improves product consistency and quality. With the rapid development of electronic technology, computer technology, control technology and other fields, automated manufacturing technology has made breakthrough progress. In particular, the emergence of key components such as programmable logic controllers (PLCs), sensors, actuators, etc. has made automated control in the production process a reality. In order to maintain competitiveness, enterprises need to continuously improve production efficiency, reduce costs and shorten product time to market. Automated manufacturing technology is one of the important means to meet these needs.

[0003] In the carbon black production process, furnace carbon black production is the most commonly used. In the furnace carbon black production, the raw oil gun needs to be inserted into the oil hole of the carbon black reactor to spray oil and burn to produce carbon black. However, as the scale of carbon black production equipment becomes larger and larger, the length of the existing raw oil gun has increased to 1.5 meters to 2 meters, and the weight is 60 kilograms to 150 kilograms. In the traditional process, the entry and exit operation of the raw oil gun mainly depends on manual operation, but manual operation has problems such as low efficiency, difficulty in ensuring accuracy, and great safety hazards.

[0004] After searching, the patent announcement number CN216890749U discloses an automatic plug-in and pull-out mechanism for a raw material oil gun for a carbon black reactor, which is designed for the field of carbon black production. The utility model includes a base frame, a stabilizing seat and a fixed plate, two groups of hydraulic pumps are installed on both sides of the interior of the base frame, two groups of telescopic legs are movably installed on both sides of the interior of the base frame, a workbench is installed on the top of the base frame, two groups of maintenance boxes are installed on both sides of the front of the base frame, two groups of welding seats are installed on both sides of the exterior of the base frame, an auxiliary frame is installed on the top of the workbench, two groups of pipe openings are installed inside the auxiliary frame, and a camera is installed on one side of the exterior of the auxiliary frame, a stabilizing seat is installed on one side of the top of the workbench, an electric telescopic rod is installed on one side of the stabilizing seat, a fixed plate is installed on the output end of the electric telescopic rod, two groups of threaded sleeves are provided on both sides of the fixed plate, a threaded rod is movably installed inside the threaded sleeve, and a rubber clamping sheet is installed on one side of the threaded rod.

Therefore, designing an automatic precise in and out mechanism for a crude oil gun with a high degree of automation and its use method has become a technical problem that needs to be solved at present.

Through the movement of the AGV trolley 23, the staff only needs to complete the replacement and maintenance of the crude oil gun 25 in a safe area, and the staff does not need to work near the carbon black reactor 24, thereby greatly reducing the occurrence of safety accidents. Through the coordination of the walking structure, the position adjustment structure and the automatic entry and exit structure, the crude oil gun 25 can achieve position and direction adjustment of the front, rear, left, right, up, down and pitch angles, so that the automatic entry and exit mechanism has high versatility and good adaptation effect when coordinated with carbon black reactors 24 of different structures and types. An oil hole sealing structure is adopted. When the crude oil gun 25 needs maintenance, repair and replacement, after the crude oil gun 25 is pulled out of the oil hole of the carbon black reactor 24, the oil hole sealing structure is used to quickly seal the oil hole of the carbon black reactor 24 to prevent flames from spraying out of the carbon black reactor 24, thereby reducing the occurrence of safety accidents.

[0035] Through the cooperation of the walking structure, the position adjustment structure and the automatic in-and-out structure, the raw oil gun 25 can realize the position adjustment of the front, back, left, right, up, down and pitch angle. When the oil hole of the carbon black reaction furnace 24 is set horizontally, tilted upward or tilted downward, the raw oil gun 25 can be accurately aligned with the oil hole for automatic in-and-out operation. An oil hole covering structure is adopted. When the crude oil gun 25 needs to be repaired or replaced during operation, the plug 20 is plugged into the oil hole using the oil hole covering structure after the crude oil gun 25 is pulled out of the oil hole, so as to prevent the flame in the carbon black reactor 24 from spraying out through the oil hole and causing a safety accident. When the AGV trolley 23 replaces the crude oil gun 25 and returns to the workstation, the plug 20 is recovered using the oil hole covering structure, and the replaced crude oil gun 25 is reinserted into the oil hole for carbon black production operations.

[0036] The automatic in-and-out structure includes a mounting tube 7 and a sleeve. The sleeve can be easily in and out of the mounting tube 7. A plurality of sleeves can be prepared on a workbench in a safe area. The spare crude oil gun 25 can be placed in the spare sleeve. Different crude oil guns 25 can be quickly replaced on the mounting tube 7 according to the operation requirements. A workbench is provided in the safety area, and the safety area is far away from the carbon black reactor 24 to prevent workers from close contact with the high temperature and heat environment. The installation tube 7 is made flush with the workbench through the cooperation of the walking structure, the position adjustment structure and the automatic entry and exit structure. The installation tube 7 can push the casing onto the workbench through the first motor 11. When workers install and remove the casing, they do not need to move the crude oil gun 25 time-consuming and laboriously, and can easily install and remove the casing.

[0037] In summary, the automatic precise entry and exit mechanism for a crude oil gun 25 and a method of using the same provided by the present invention are compared with the existing automatic precise entry and exit mechanism for a crude oil gun 25; through the movement of the AGV trolley 23, the staff only needs to complete the replacement and maintenance of the crude oil gun 25 in a safe area, and the staff does not need to work near the carbon black reactor 24, which greatly reduces the occurrence of safety accidents; through the cooperation of the walking structure, the position adjustment structure and the automatic entry and exit structure, the crude oil gun 25 can achieve position and direction adjustment of the front, back, left, right, up, down and pitch angles, so that the automatic entry and exit mechanism has high versatility and good adaptation effect when cooperating with carbon black reactors 24 of different structures and types; an oil hole covering structure is adopted, and when the crude oil gun 25 needs maintenance, repair and replacement, after the crude oil gun 25 is pulled out of the oil hole of the carbon black reactor 24, the oil hole covering structure is used to quickly cover the oil hole of the carbon black reactor 24 to prevent flames from spraying out of the carbon black reactor 24, thereby reducing the occurrence of safety accidents.

[0038] The AGV trolley 23 used in the present invention is an existing conventional technology, and its structural features are not described in detail.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
