[0004] However, the existing oxygen-enriched combustion system for all-waste cement clinker also has certain defects. The existing oxygen-enriched combustion system for all-waste cement clinker mostly uses oxygen and pulverized coal in combination to complete the combustion in the rotary kiln. Due to the influence of factors such as the moisture content and particle size of pulverized coal, it is very easy to cause large and unstable temperature fluctuations in the rotary kiln. Summary of the Invention

[0005] The purpose of this invention is to provide an oxygen-enriched combustion system for all-waste cement clinker, which solves the problem that existing oxygen-enriched combustion systems for all-waste cement clinker often directly use oxygen and pulverized coal to complete the combustion in the rotary kiln. Due to the influence of factors such as the moisture content and particle size of the pulverized coal, the temperature in the rotary kiln is prone to large fluctuations and instability.

[0006] To achieve the above objectives, this utility model provides an oxygen-enriched combustion system for all-waste cement clinker, including a base. A rotary kiln is mounted on the upper end of the base via a driver. A feed box is fixedly connected to the upper end of the base and to the left side of the rotary kiln. A feed pipe is fixedly connected to the right end of the feed box and is rotatably connected to the rotary kiln. A feeding mechanism is provided on the feed box. An installation shell is slidably connected to the inner wall of the feed box. A hot air blower is installed inside the installation shell. A fixing lug is fixedly connected to the left end of the feed box and to the upper side of the installation shell. An insert plate is slidably connected to the inner wall of the fixing lug and is slidably connected to the installation shell.

[0007] The principle of this utility model is as follows: by pulling the end ear upward, the insert plate slides along the inner wall of the fixed ear, causing the spring to deform. Then, the mounting shell is pushed into the feed box, and the positioning rod is inserted into the feed box to quickly position the mounting shell. The end ear is then released to allow the spring to return to its original deformation, pushing the insert plate into the mounting shell to limit the insertion of the mounting shell and make the mounting shell stable. Under the action of the hot air blower, the coal powder can be dried and dehumidified to reduce the moisture content of the coal powder, improve the subsequent calorific value utilization rate, and reduce the problem of temperature fluctuation and instability in the kiln.

[0008] The output shaft is driven by a servo motor to rotate, which in turn drives the cam to rotate. The long end of the cam presses against the end ball, pushing the telescopic rod to slide along the inner wall of the feed box and moving the feeding box. This causes the second spring to deform. As the feeding box moves, it can also drive the guide rod to slide along the inner wall of the feed box, ensuring the stable movement of the feeding box. When the long end of the cam disengages from the end ball, the second spring returns to its original deformation, pulling the feeding box to reset. This cycle repeats, allowing the feeding box to move and vibrate the screen, screening and feeding coal powder. This not only ensures the consistency of coal powder fineness but also avoids screen clogging.

[0009] The beneficial effects of this utility model are as follows: This solution pushes the mounting shell into the feeding box, and under the action of the positioning rod, the mounting shell can be quickly positioned for use. Under the action of the insert plate, spring one and other structures, the mounting shell can be inserted and limited, so that the mounting shell is in a stable position. Under the action of the hot air fan, the coal powder can be dried to reduce the moisture content of the coal powder combustion, improve the subsequent calorific value utilization rate, and reduce the problem of temperature fluctuation and instability in the kiln. Through the setting of the feeding box and screen, the coal powder can be screened and fed to ensure the uniformity of coal powder fineness. Under the action of the servo motor, cam, spring two and other structures, the feeding box can drive the screen to move back and forth and vibrate, which not only ensures a good feeding effect, but also dynamically screens the coal powder and avoids the problem of screen clogging.

[0010] Furthermore, a positioning rod is fixedly connected to the lower end of the mounting shell, and the positioning rod is slidably connected to the feed box. The mounting shell can be inserted and positioned for use by setting the positioning rod.

[0011] Furthermore, a spring is welded to the lower end of the fixing ear, and the other end of the spring is welded to the horizontal block of the insert plate. The spring can be used to tighten the insert plate.

[0012] Furthermore, the upper end of the insert plate is fixedly connected with an end lug, which is slidably connected to the feed box. The end lug facilitates the movement of the insert plate by pulling it.

[0013] Furthermore, the feeding mechanism includes a telescopic rod, which is slidably connected to the inner wall of the feeding box. A feeding box is fixedly connected to the front of the telescopic rod, and the feeding box is located inside the feeding box. A screen is fixedly connected to the inner wall of the feeding box, and a guide rod is fixedly connected to the front of the feeding box. The guide rod is slidably connected to the feeding box. A second spring is welded to the back of the feeding box, and the other end of the second spring is welded to the feeding box. An end ball is fixedly connected to the back of the telescopic rod. A servo motor is mounted on the back of the feeding box, below the telescopic rod, via a support. A cam is fixedly sleeved on the outside of the output shaft of the servo motor, and the cam contacts the end ball. Through the coordinated use of the servo motor, cam, and second spring, the feeding box can drive the screen to move back and forth and vibrate, thereby screening and feeding the coal powder.

[0014] Furthermore, two guide rods are provided, which are symmetrically distributed on the feeding box. The guide rods ensure the stable movement of the feeding box.

[0015] Furthermore, two springs are provided, and the two springs are evenly distributed on the feeding box. The feeding box can be connected and used by means of the springs. Attached Figure Description

[0023] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this embodiment provides an oxygen-enriched combustion system for all-waste cement clinker, including a base 1. A rotary kiln 2 is mounted on the upper end of the base 1 via a driver. A feed box 3 is fixedly connected to the upper end of the base 1 and to the left side of the rotary kiln 2. A feed pipe 4 is fixedly connected to the right end of the feed box 3. The feed pipe 4 is rotatably connected to the rotary kiln 2. An installation shell 6 is slidably connected to the inner wall of the feed box 3. A hot air blower 7 is installed inside the installation shell 6. A fixing ear 9 is fixedly connected to the left end of the feed box 3 and to the upper side of the installation shell 6. An insert plate 10 is slidably connected to the inner wall of the fixing ear 9. The insert plate 10 is slidably connected to the installation shell 6.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a positioning rod 8 is fixedly connected to the lower end of the mounting shell 6. The positioning rod 8 is slidably connected to the feed box 3. The mounting shell 6 can be inserted and positioned by the positioning rod 8. A spring 12 is welded to the lower end of the fixing ear 9. The other end of the spring 12 is welded to the horizontal block of the insert plate 10. The insert plate 10 can be tightened by the spring 12. An end ear 11 is fixedly connected to the upper end of the insert plate 10. The end ear 11 is slidably connected to the feed box 3. The end ear 11 facilitates the movement of the insert plate 10 by pulling it.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a feeding mechanism 5 is provided on the feeding box 3. The feeding mechanism 5 includes a telescopic rod 50. The telescopic rod 50 is slidably connected to the inner wall of the feeding box 3. A feeding box 51 is fixedly connected to the front of the telescopic rod 50. The feeding box 51 is located inside the feeding box 3. A screen 52 is fixedly connected to the inner wall of the feeding box 51. A guide rod 53 is fixedly connected to the front of the feeding box 51. The guide rod 53 is slidably connected to the feeding box 3. A second spring 54 is welded to the back of the feeding box 51. The other end of the second spring 54... Welded to the feed box 3, the telescopic rod 50 has an end ball 55 fixedly connected to its back. The back of the feed box 3, located below the telescopic rod 50, is equipped with a servo motor 56 via a support. A cam 57 is fixedly sleeved on the outside of the output shaft of the servo motor 56. The cam 57 contacts the end ball 55. Through the combined use of the servo motor 56, cam 57, spring 54, and other structures, the feed box 51 can drive the screen 52 to move back and forth and vibrate, so as to screen and feed the coal powder.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, there are two guide rods 53, which are symmetrically distributed on the feed box 3. The guide rods 53 ensure the stable movement of the feed box 51. There are also two springs 54, which are evenly distributed on the feed box 51. The springs 54 can be used to connect the feed box 51.

[0027] The specific implementation process of this utility model is as follows: By pulling the end ear 11 upward, the insertion plate 10 is driven to slide along the inner wall of the fixed ear 9, causing the spring 12 to deform. Then, the mounting shell 6 is pushed into the feed box 3, so that the positioning rod 8 is inserted into the feed box 3, and the mounting shell 6 is quickly positioned. The end ear 11 is then released so that the spring 12 returns to its original deformation, so that the insertion plate 10 is pushed into the mounting shell 6, and the mounting shell 6 is inserted and limited, so that the mounting shell 6 is stable. Under the action of the hot air blower 7, the coal powder can be dried and dehumidified to reduce the moisture content of the coal powder, improve the subsequent calorific value utilization rate, and reduce the problem of temperature fluctuation and instability in the kiln.

[0028] The output shaft is driven by the servo motor 56 to rotate, which in turn drives the cam 57 to rotate. The long end of the cam 57 presses against the end ball 55, pushing the telescopic rod 50 to slide along the inner wall of the feed box 3 and moving the feeding box 51. This causes the second spring 54 to deform. When the feeding box 51 moves, it can drive the guide rod 53 to slide along the inner wall of the feed box 3 to ensure the stable movement of the feeding box 51. When the long end of the cam 57 disengages from the end ball 55, the second spring 54 returns to its original deformation, pulling the feeding box 51 to reset. This cycle repeats, allowing the feeding box 51 to move and vibrate the screen 52 to screen and feed coal powder. This not only ensures the consistency of coal powder fineness but also avoids the problem of screen 52 clogging.

[0029] This solution pushes the mounting shell 6 into the feed box 3. Under the action of the positioning rod 8, the mounting shell 6 can be quickly positioned. Under the action of the insert plate 10, spring 12 and other structures, the mounting shell 6 can be inserted and limited, so that the mounting shell 6 is in a stable position. Under the action of the hot air fan 7, the coal powder can be dried to reduce the moisture content of the coal powder combustion, improve the subsequent calorific value utilization rate, and reduce the problem of temperature fluctuation and instability in the kiln. Through the setting of the feeding box 51 and the screen 52, the coal powder can be screened and fed to ensure the uniformity of coal powder fineness. Under the action of the servo motor 56, cam 57, spring 54 and other structures, the feeding box 51 can drive the screen 52 to move back and forth and vibrate, which not only ensures a good feeding effect, but also dynamically screens the coal powder and avoids the problem of screen 52 clogging.
