Description

Technical Field

[0002] Petroleum coke calcination refers to the process of heating petroleum coke at high temperature. Petroleum coke is a carbonaceous substance left over from the oil refining process, with high fixed carbon content and low volatile content. The calcination process is mainly to change the physical and chemical properties of petroleum coke, making it more suitable for use in industrial fields such as casting, steelmaking, and aluminum electrolysis. This forging method usually requires the use of a pot calcining furnace, which is often equipped with an automatic temperature control device.

[0003] In the automatic temperature control device of a traditional pot-type calcining furnace, the temperature sensor is usually installed at a key position inside the calcining furnace to monitor the temperature of the calcining furnace in real time. The controller is the core component of the automatic temperature control device, which is responsible for receiving the signal from the temperature sensor and performing comparison and control according to the preset temperature setting value. The actuator is the output component of the controller, which is responsible for adjusting the operating parameters inside the calcining furnace according to the instructions of the controller to achieve temperature regulation and control. Common actuators include electric valves, heating elements, etc., which adjust parameters such as the heating power inside the calcining furnace according to the control signal.

[0004] However, traditional tank calcining furnace automatic temperature control devices often only use valves to control heating power, including valves for adjusting fuel supply. This adjustment method cannot adjust the gas flow and wind speed inside the calcining furnace. The fuel supply adjustment method is relatively simple and cannot control the gas flow in the calcining furnace, which reduces the uniformity of temperature distribution. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an automatic temperature control device for a tank-type calcining furnace for calcining petroleum coke, aiming to improve the problem that the adjustment method of the traditional tank-type calcining furnace automatic temperature control device cannot adjust the gas flow and wind speed inside the calcining furnace, the fuel supply adjustment method is relatively single, and the gas flow in the calcining furnace cannot be controlled, which reduces the uniformity of the temperature distribution.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an automatic temperature control device of a pot-type calcining furnace for calcining petroleum coke, comprising a furnace body, a side wall of the furnace body is fixedly connected with an air duct, a connecting pipe is fixedly connected inside the air duct, a side wall of the connecting pipe is fixedly connected with a connecting plate, a side wall of the connecting plate is fixedly connected with a turntable, a side wall of the connecting plate is fixedly connected with a motor, an output end of the motor is fixedly connected with a rotating wheel, the rotating wheel is rotatably connected to the inside of the turntable, a second clamping shaft is fixedly connected to the side wall of the connecting plate, an eccentric shaft is fixedly connected to the side wall of the rotating wheel, a slide frame is rotatably connected to the outer wall of the eccentric shaft, a second clamping shaft is slidably connected to the inside of the slide frame, a plurality of first clamping shafts are fixedly connected to the side wall of the turntable, a slide frame is rotatably connected to one side wall of the slide frame, a slide frame is rotatably connected to the side wall of the slide frame, a slider is slidably connected to the inside of the connecting plate, a plurality of air guide ports are opened inside the turntable, and a control component is provided on the side wall of the furnace body.

[0008] Furthermore, a connecting piece is fixedly connected to the top of the electrical control cabinet, a fixing frame is fixedly connected to the side wall of the connecting piece, and a cabinet cover is slidably connected to the inside of the electrical control cabinet.

[0009] Furthermore, a cylinder is fixedly connected to the bottom of the fixing frame, and a push rod is fixedly connected to the output end of the cylinder.

[0010] Furthermore, one end of the push rod is fixedly connected to a connecting square tube, and both ends of the connecting square tube are rotatably connected to slide plates.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: an automatic temperature control device for a pot-type calcining furnace for calcining petroleum coke, comprising a furnace body 1, a duct 2 is fixedly connected to the side wall of the furnace body 1, a connecting pipe 3 is fixedly connected inside the duct 2, a connecting plate 4 is fixedly connected to the side wall of the connecting pipe 3, a turntable 5 is fixedly connected to the side wall of the connecting plate 4, a motor 6 is fixedly connected to the side wall of the connecting plate 4, a runner 7 is fixedly connected to the output end of the motor 6, the runner 7 is rotatably connected to the inside of the turntable 5, a clamping shaft 2 11 is fixedly connected to the side wall of the connecting plate 4, an eccentric shaft 8 is fixedly connected to the side wall of the runner 7, a slide 10 is rotatably connected to the outer wall of the eccentric shaft 8, the clamping shaft 2 11 is slidably connected to the inside of the slide 10, a plurality of clamping shafts 9 are fixedly connected to the side wall of the turntable 5, a slide 2 12 is rotatably connected to the side wall of the slide 2 12, a slider 13 is rotatably connected to the side wall of the slider 12, the slider 13 is slidably connected to the inside of the connecting plate 4, a plurality of air guide ports 14 are opened inside the turntable 5, and a control component is provided on the side wall of the furnace body 1.

[0025] Specifically, the motor 6 is started, and the motor 6 transmits power to the runner 7 through mechanical transmission, so that the runner 7 starts to rotate. The runner 7 is installed on the turntable 5 in the calcining furnace. While the runner 7 rotates, under the action of the eccentric shaft 8, the slide 10 starts to move and changes its inclination angle. The movement of the slide 10 also drives the clamping shaft 2 11 to slide inside it, and at the same time drives the rotation of the slide 2 12. The rotation of the slide 2 12 further pulls the slider 13, so that the slider 13 slides vertically inside the connecting plate 4. The vertical sliding of the connecting plate 4 is coordinated with the sliding of the bottom of the clamping shaft 2 11 inside the slide 10 outside the clamping shaft 9 through the setting of multiple clamping shafts 9. Finally, the turntable 5 rotates periodically on the side wall of the connecting plate 4. Through the air guide port 14, the gas flow and wind speed inside the calcining furnace can be adjusted according to the control signal, which can effectively control the gas flow in the calcining furnace, thereby achieving uniformity of temperature distribution, ensuring that the petroleum coke is uniformly processed at high temperature, and improving production efficiency and product quality.

[0026] Reference Figure 1 and 4 The control component includes an electrical control cabinet 15, which is fixedly connected to the side wall of the furnace body 1. A connecting piece 17 is fixedly connected to the top of the electrical control cabinet 15, and a fixing frame 18 is fixedly connected to the side wall of the connecting piece 17. A cabinet cover 16 is slidably connected inside the electrical control cabinet 15, and a cylinder 19 is fixedly connected to the bottom of the fixing frame 18. A push rod 20 is fixedly connected to the output end of the cylinder 19, and one end of the push rod 20 is fixedly connected to a connecting square tube 21, and both ends of the connecting square tube 21 are rotatably connected to a slide plate 23. Multiple slides 22 are fixedly connected to the two sides of the fixing frame 18, and multiple pulleys 25 are rotatably connected to the side wall of the slide plate 23. The pulley 25 is slidably connected inside the slide plate 22, and multiple connecting rods 24 are rotatably connected to the side wall of the slide plate 23, and one end of the connecting rod 24 is rotatably connected to the side wall of the cabinet cover 16.

[0027] Specifically, the cylinder 19 is started, and the cylinder 19 applies a push-pull force to the connecting square tube 21 through the push rod 20. The movement of the push rod 20 pulls the connecting square tube 21. This action causes the connecting square tube 21 to start moving and drives the slides 23 on both sides thereof to move vertically. The pulley 25 inside the slide 23 slides in the slide 22, thereby making the vertical movement of the slide 23 more stable. At the same time, the connecting member 17 plays a role in firmly fixing the fixing frame 18 to ensure the stability of the mechanical structure. When the slide 23 moves vertically, it pulls the side wall of the connecting rod 24, and the connecting rod 24 rotates and changes its inclination angle. This action allows the cabinet cover 16 to be pulled during the movement of the connecting rod 24, so that it slides out from the inside of the electrical control cabinet 15. This structure not only provides effective protection for the inside of the electrical control cabinet 15, but also ensures that the operator can conveniently perform maintenance. Through this mechanical design, the normal operation and safe operation of the device can be ensured, while improving the maintenance efficiency and the convenience of operation.

[0028] Working principle: when it is necessary to adjust the air flow rate inside the furnace body 1, first start the motor 6. The motor 6 outputs a rotating force to the wheel 7, which drives the wheel 7 to rotate inside the turntable 5. At this time, the eccentric shaft 8 drives the slide 10 to move and change the inclination angle. While the slide 10 moves, the card shaft 2 11 slides inside the slide 10, and at the same time drives the slide 2 12 on its side wall to rotate and then pull the slider 13, so that the slider 13 slides vertically inside the connecting plate 4. Through the arrangement of multiple card shafts 9, while the card shaft 2 11 moves, its bottom slides outside the card shaft 19, which can pull the turntable 5 to make it rotate periodically on the side wall of the connecting plate 4. In this process, the gas flow and wind speed inside the calcining furnace can be adjusted according to the control signal through the air guide port 14, so as to control the gas flow in the calcining furnace and achieve temperature control. The uniformity of the degree distribution is ensured. When the interior of the electrical control cabinet 15 needs to be inspected and maintained, the cylinder 19 is started. The cylinder 19 outputs a push-pull force to the push rod 20, so that the push rod 20 pulls the connecting square tube 21. The connecting square tube 21 moves while driving the slides 23 on both sides thereof to move vertically. At this time, the pulley 25 inside the slide 23 slides in the slide 22, and the connecting member 17 plays a role in fixing the fixed frame 18. The slide 23 slides while pulling the connecting rod 24 on its side wall, and the connecting rod 24 can rotate and change the inclination angle. During the movement of the connecting rod 24, the cabinet cover 16 is pulled to make it slide out of the electrical control cabinet 15. Due to this structure, the electrical control center inside the electrical control cabinet 15 can be protected and the convenient maintenance function can be achieved by opening and closing the control cabinet cover 16, which can ensure the normal operation and safe operation of the device.
