DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1: This embodiment Figure 1-Figure 11 As shown, in order to solve the problem of fuel waste in existing sintering machines, the process of automatically adding coke powder to assist combustion is disclosed, and the effect of saving resources by the energy-saving system is achieved. The specific contents are as follows:

[0039] The sub-addition cylinder 1 and the feed port 2 opened at the upper end of the sub-addition cylinder 1; the lower end of the sub-addition cylinder 1 is provided with a discharge port 5, the outer side of the sub-addition cylinder 1 is fixedly installed with a support plate 3, and the lower end of the support plate 3 is fixedly installed with a support frame 4, and the interior of the support frame 4 is fixedly installed with two sets of directional plates 7, the lower end of the sub-addition cylinder 1 is provided with a switch door assembly 6, and the switch door assembly 6 is located outside the discharge port 5, and the interior of the support frame 4 is provided with an automatic uniform sowing structure, the sowing structure includes a moving frame 21 and a guide plate 27, and the moving frame 21 and the guide plate 27 are fixedly installed on the outer side of the moving plate 20, and the interior of the moving frame 21 is rotatably installed with a driving mechanism. A rotating member 23 is fixedly installed at one end of the driving gear 22 close to the dispensing cylinder 1, a fixed rack 26 is fixedly installed inside the support frame 4, and the fixed rack 26 is meshed and connected with the driving gear 22, and the moving frame 21 is located on the outside of the driving gear 22 and the fixed rack 26, a connecting member 24 is rotatably installed at one end of the rotating member 23 away from the driving gear 22, and the connecting member 24 is fixedly installed at one end away from the rotating member 23 and a fine-mesh screen frame 25 is rotatably installed at one end, and the lower ends of the fine-mesh screen frame 25 and the guide plate 27 are provided with metal rollers 28, and two groups of guide plates 27 and directional plates 7 are provided.

[0040] When the sintering machine fuel adding energy-saving system is in operation, the coke powder to be burned is first transported by a sealed tank truck, and after the sealed tank truck completes the transportation, it needs to be added to the interior of the bag dust collector on the top of the silo for primary treatment. After the coke powder completes the primary treatment, it needs to be transported to the interior of the fuel buffer silo, and then it can be transported to the interior of the adding cylinder 1 through the belt scale provided at the lower end of the fuel buffer silo. At this time, the coke powder can be evenly added to the upper end of the sintering machine through the adding cylinder 1, and the coke powder needs to be sprinkled on the upper end of the fuel;

[0041] During the operation of the system, coke powder needs to be added to the upper end of the sintering machine through the distribution cylinder 1, so as to increase and reduce the sintering solid consumption and ignition gas consumption. At this time, the belt scale needs to add the coke powder fuel inside the fuel buffer bin to the inside of the feed port 2. At this time, the coke powder inside the feed port 2 will enter the inside of the distribution cylinder 1, and the coke powder inside the distribution cylinder 1 will accumulate at its lower end and can be scattered on the upper end of the fine-pore screen frame 25 by opening the switch door assembly 6. At this time, the drive motor 8 will work and drive the output shaft 9 to The output shaft 9 rotates in the forward direction, and the rotating cylinder 10 drives the moving cylinder 16 to rotate. At this time, the ratchet 14 and the ratchet wheel 15 are in meshing state, and the torsion spring 13 is in an expanded state. The moving cylinder 16 rotates to drive the connecting rod 18 to rotate through the reciprocating screw 17, and the connecting rod 18 rotates to drive the moving plate 20 and the moving frame 21 to reciprocate. The moving cylinder 16 revolves around the center of the rotating cylinder 10, and the two sets of bevel gears inside the first bevel gear assembly 19 rotate relatively stationary.

[0042] The movement of the movable frame 21 will drive the driving gear 22 to move, and the movement of the driving gear 22 will rotate under the action of the fixed rack 26. At this time, the driving gear 22 will drive the rotating member 23 to rotate and make the connecting member 24 perform horizontal reciprocating motion. At this time, the connecting member 24 will drive the fine-mesh screen frame 25 to perform horizontal reciprocating motion, so that the coke powder inside the fine-mesh screen frame 25 can be sifted and fall on the upper end of the sintering machine. The coke powder is scattered by screening through the fine-mesh screen frame 25, which can ensure the uniformity of the coke powder scattering, and the movable plate 20 will drive the guide plate 27 to move, and the guide plate 27 will move on the upper end of the directional plate 7 through the metal roller 28, and the fine-mesh screen frame 25 will also move on the upper end of the guide plate 27 through the metal roller 28 during the reciprocating motion, thereby ensuring the balance of the reciprocating screening of the fine-mesh screen frame 25.

[0043] Embodiment 2: This embodiment is as follows Figure 1-Figure 7 As shown, in order to solve the problem of difficulty in controlling the coke powder scattering range for different sintering machines, the process of adjusting the coke powder scattering range of the divided addition energy-saving system is disclosed, and the effect of the divided addition energy-saving system being able to accurately scatter the coke powder is achieved. The specific contents are as follows:

[0044] The support frame 4 is provided with a control structure for adjusting the coke powder spreading range, and the control structure includes a drive motor 8 and an output shaft 9. The drive motor 8 is fixedly mounted on the outside of the distribution cylinder 1, and the output end of the drive motor 8 is fixedly mounted with the output shaft 9, and the output shaft 9 is rotatably mounted on the outside of the distribution cylinder 1, and at the same time, a rotating cylinder 10 is rotatably mounted on the outside of the lower end of the output shaft 9, and two groups of rotating disks 11 are fixedly mounted inside the rotating cylinder 10, and a fixed shaft 12 is fixedly mounted inside the rotating disk 11, and a ratchet 14 is rotatably mounted on the outside of the fixed shaft 12, and a torsion spring is arranged between the ratchet 14 and the fixed shaft 12. Spring 13, a ratchet 15 is fixedly installed on the outer side of the output shaft 9, and the ratchet 15 is located inside the rotating disk 11, and the ratchet 15 is meshed and connected with the ratchet 14, and the ratchet 15 and the ratchet 14 are correspondingly arranged inside the rotating disk 11, a moving cylinder 16 is rotatably installed inside the rotating cylinder 10, and a reciprocating screw 17 is installed on the internal thread of the moving cylinder 16, and a first bevel gear assembly 19 is arranged on the outer side of the moving cylinder 16 and the output shaft 9, a connecting rod 18 is rotatably installed on the lower end of the side of the reciprocating screw 17 away from the moving cylinder 16, and a moving plate 20 is rotatably installed on the end of the connecting rod 18 away from the reciprocating screw 17

[0045] When the sintering machine fuel addition energy-saving system is working, the reciprocating screening range of the fine-pore screen frame 25 can be controlled according to the size of the sintering machine to avoid the situation where the coke powder addition range does not match the sintering machine. At this time, it is necessary to control the length of the reciprocating screw 17 outside the moving cylinder 16 to change the movement distance of the fine-pore screen frame 25;

[0046] During this process, it is necessary to drive the output shaft 9 to rotate in the opposite direction through the driving motor 8. The reverse rotation of the output shaft 9 will cause the ratchet 14 and the ratchet wheel 15 to be in a separated state, and the torsion spring 13 will be in a contracted state. The reverse rotation of the output shaft 9 will drive the moving cylinder 16 to rotate through the first bevel gear assembly 19. At this time, the rotating cylinder 10 will be stationary, and the moving cylinder 16 will rotate inside the rotating cylinder 10. The movement of the moving cylinder 16 will cause the reciprocating screw 17 inside it to move inside the moving cylinder 16, thereby changing the position of the reciprocating screw 17 inside the moving cylinder 16, and then changing the length of the reciprocating screw 17 and the moving cylinder 16, so that the movement range of the fine-pore screen frame 25 is changed, avoiding the waste caused by inaccurate scattering of coke powder inside the fine-pore screen frame 25, so that the coke powder can be evenly added to the upper end of the sintering machine fuel, ensuring the working effect of the addition system.

[0047] Embodiment 3: This embodiment is as follows Figure 1-Figure 2 and Figure 8 As shown, in order to solve the problem of coke powder adhering to the inside of the adding cylinder 1, the process of automatically cleaning the coke powder inside the adding cylinder 1 is disclosed, so that the adding cylinder 1 can discharge materials normally. The specific contents are as follows:

[0048] A cleaning structure for preventing coke powder from adhering is provided inside the distribution cylinder 1, and the cleaning structure includes a moving rod 29, and the moving rod 29 is rotatably installed inside the distribution cylinder 1, and a third bevel gear assembly 33 is provided on the end of the moving rod 29 away from the distribution cylinder 1 and the outer side of the output shaft 9, the cleaning structure also includes a positioning rod 32, and the positioning rod 32 is fixedly installed inside the lower end of the distribution cylinder 1, and a center rod 30 is rotatably installed inside the positioning rod 32, and a second bevel gear assembly 31 is provided on the outer sides of the center rod 30 and the moving rod 29, two groups of cleaning rods 34 are fixedly installed on the lower end of the center rod 30, and the lower end of the cleaning rod 34 is inclined, and the cleaning rod 34 is tightly fitted with the inner surface of the lower end of the distribution cylinder 1, and two groups of cleaning rods 34 are provided inside the distribution cylinder 1.

[0049] When the sintering machine fuel adding energy-saving system is working, the addition and scattering of coke powder needs to be completed through the adding cylinder 1. In order to ensure that the coke powder inside the adding cylinder 1 can be accurately added to the inside of the fine-mesh screen frame 25, the discharge port 5 at the lower end of the adding cylinder 1 needs to be a funnel-shaped structure. However, the design of this method easily leads to the coke powder sticking inside the lower end of the adding cylinder 1. In order to avoid the coke powder sticking, the inclined position inside the lower end of the adding cylinder 1 needs to be cleaned by the cleaning rod 34.

[0050] During this process, the driving motor 8 will drive the output shaft 9 to rotate, and the rotation of the output shaft 9 will drive the moving rod 29 to rotate through the third bevel gear assembly 33, and the rotation of the moving rod 29 will drive the center rod 30 to rotate through the second bevel gear assembly 31. At this time, the two groups of cleaning rods 34 on the outside of the center rod 30 will rotate synchronously with the cleaning rod 34, so that the cleaning rod 34 can clean the coke powder adhered to the inside of the lower end of the dispensing cylinder 1, thereby avoiding the adhesion of coke powder at the lower end of the dispensing cylinder 1, increasing the overall practicality.

[0051] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
