[0002] As a key equipment, sintering machine plays a vital role in the steel industry. Its core function is to convert iron ore powder, coal powder and other related raw materials into solid blocks through high-temperature sintering. This process is an indispensable pre-step in the blast furnace ironmaking production process. During the operation of the sintering machine, the raw materials will experience high temperature, high pressure and a complex environment full of dust.

[0023] A method for optimizing the sealing of a sintering machine part is provided, using the above-mentioned sintering machine part sealing optimization device to complete the following steps:

[0024] Step 1: Initial preparation

[0025] Install the sintering machine part sealing optimization device at the designated position of the sintering machine, ensure that the supporting mechanism is firmly supported on the supporting frame of the sintering machine, and the gas injection assembly is reliably connected to the external gas source;

[0026] Check and adjust the movable plate assembly of the sealing mechanism to ensure that it can rotate freely and reset under the action of the No. 1 torsion spring;

[0027] Confirm that the contact between the driving wheel assembly of the driving mechanism and the trolley is good, and the push frame assembly can move smoothly driven by the driving wheel assembly;

[0028] Step 2: Sealing process

[0029] When the trolley enters the support frame area along the track, the movement of the trolley drives the drive wheel assembly to rotate on the mounting frame assembly;

[0030] The rotation of the driving wheel assembly drives the movable set in the push frame assembly to move upward along the guide rod through the gear transmission;

[0031] The upward movement of the movable kit drives the movable plate assembly to rotate through the push block, so that the rubber fits tightly to the edge of the trolley to achieve a sealing effect;

[0032] At the same time, as the movable kit moves, the spring is compressed, playing a buffering role and protecting the sealing mechanism from impact;

[0033] Step 3: Sintering

[0034] After the sealing is completed, the gas injection assembly is started to deliver gas to the gas injection rack through the gas transmission pipe;

[0035] The gas is sprayed out through the nozzle and ignited to sinter the materials in the trolley;

[0036] During the sintering process, the sealing mechanism ensures that the gas in the trolley does not leak, thus ensuring the sintering efficiency and product quality;

[0037] Step 4: Reset and wait

[0038] When the trolley completes sintering and leaves the support frame area, the No. 2 torsion spring in the drive mechanism is reset, driving the push frame assembly and the movable kit to move downward;

[0039] At the same time, the No. 1 torsion spring in the sealing mechanism is also reset, driving the movable plate assembly to rotate and reset, ready to welcome the arrival of the next car;

[0040] The device enters standby mode, waiting for the start of the next round of sintering operation;

[0041] Step 5: Maintenance and Inspection

[0042] Regularly inspect and maintain the sealing optimization device of the sintering machine, including cleaning, lubrication and tightening;

[0043] Check whether the rubber of the sealing mechanism is severely worn and replace it if necessary;

[0044] Check whether the gears and bearings of the drive mechanism are worn or damaged, and repair or replace them in time if necessary.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] The invention ensures that the movable plate assembly can fit the edge of the trolley in real time and accurately through a cleverly designed drive mechanism, including direct interaction between the drive wheel assembly and the trolley, and responsive movement of the push frame assembly. This innovative mechanism enables effective sealing in a dynamic process, significantly reducing gas leakage during the sintering process. In this way, the overall sealing performance of the sintering machine is greatly improved, thereby ensuring an efficient and stable production process.

[0047] In addition, the drive mechanism is installed on the outside of the support frame, which greatly facilitates the maintenance process of the staff. The maintenance staff can easily approach the drive mechanism for daily inspection, maintenance and necessary repairs, thus ensuring the continuous and stable operation of the equipment.

[0048] In the design of the movable plate assembly and the push frame assembly, the present invention also cleverly utilizes the elastic reset characteristics of the No. 1 torsion spring and the No. 2 torsion spring. When the trolley leaves, the movable plate assembly and the push frame assembly can automatically reset to the initial state, ready for the next arrival of the trolley. This automatic reset function not only simplifies the operation process and reduces the need for manual intervention, but also significantly improves the reliability and durability of the device. Through this design, the equipment can maintain high efficiency and stability during long-term operation, further improving production efficiency and the service life of the equipment.

DETAILED DESCRIPTION

[0060] 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.

[0061] like Figures 1 to 10 As shown:

[0062] Embodiment 1: The present invention provides a sintering machine part sealing optimization device, comprising:

[0063] The supporting mechanism 1 comprises a supporting frame 11 and a gas injection assembly 12 arranged on the supporting frame 11;

[0064] The sealing mechanism 2 comprises a mounting plate assembly 21 mounted on the gas injection assembly 12, a movable plate assembly 22 rotatably engaged with the mounting plate assembly 21, and a first torsion spring 23 disposed between the mounting plate assembly 21 and the movable plate assembly 22;

[0065] The driving mechanism 3 includes a mounting frame assembly 31 mounted on the support frame 11, a driving wheel assembly 32 rotatably engaged with the mounting frame assembly 31, and a pushing frame assembly 33 disposed on the mounting frame assembly 31;

[0066] The gas spraying assembly 12 comprises a gas spraying frame 121, a gas delivery pipe 122 is fixedly connected to the upper side of the gas spraying frame 121, and a spray head 123 is fixedly connected to the lower side of the gas spraying frame 121;

[0067] The mounting plate assembly 21 includes a mounting plate body 211, and a shaft frame 212 is fixedly connected to one side of the mounting plate body 211;

[0068] The movable plate assembly 22 includes a movable plate body 221, one end of which is fixedly connected to a shaft rod 222, and the outer side of the movable plate body 221 is also fixedly connected to a rubber 223;

[0069] The shaft rod 222 is rotatably embedded in the shaft frame 212, one end of the first torsion spring 23 is embedded in the shaft frame 212, and the other end of the first torsion spring 23 is embedded in the shaft rod 222;

[0070] The first torsion spring 23 drives the movable plate body 221 vertically downward.

[0071] As can be seen from the above, during operation, when the trolley enters the support frame 11 along the track, the movement of the trolley will push the driving wheel assembly 32 to rotate on the mounting frame assembly 31, and the rotation of the driving wheel assembly 32 will drive the pushing frame assembly 33 to move upward, and the upward movement of the pushing frame assembly 33 will cause the movable plate assembly 22 to rotate and abut against the edge of the trolley, thereby playing a sealing role. The gas supply pipe 122 is connected to the external gas, and controlling the gas blowing frame 121 to work can make the nozzle 123 spray gas and ignite it to sinter the material in the trolley.

[0072] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the mounting frame assembly 31 further includes a mounting frame body 311, a first bracket 312 and a second bracket 313 are fixedly connected to one side of the mounting frame body 311, and a guide rod 314 is also fixedly connected to the upper side of the second bracket 313;

[0073] The mounting frame body 311 is fixedly mounted on the supporting frame 11 by means of screws.

[0074] Specifically, the driving wheel assembly 32 includes a connecting frame 321 , the outer side of one end of the connecting frame 321 is fixedly connected to a limiting shaft 322 , the other end of the connecting frame 321 is rotatably connected to a movable wheel 323 , and the outer side of the limiting shaft 322 is also fixedly connected to a large gear 324 .

[0075] Specifically, the pushing frame assembly 33 includes a driven frame member 331 rotatably embedded in the No. 1 bracket 312, the upper end of the driven frame member 331 is rotatably connected to a movable kit 332, a No. 2 torsion spring 333 is also arranged between the driven frame member 331 and the No. 1 bracket 312, and a push block member 334 is also fixedly connected to the outer side of the movable kit 332.

[0076] Specifically, the driven frame 331 includes a driven rod 3311 , one end of which is fixedly connected to a pinion 3312 , the other end of which is fixedly connected to a threaded column 3313 , and the outer side of the driven rod 3311 is fixedly connected to a limiting ring 3314 .

[0077] Specifically, the movable kit 332 includes a movable kit body 3321 , one end of which is fixedly connected to a guide slider 3322 , the other end of which is fixedly connected to a connecting plate 3323 , and the end of the connecting plate 3323 is also fixedly connected to an external bracket 3324 .

[0078] Specifically, the push block 334 includes an oblique push block body 3341 , one end of which is fixedly connected to a guide bracket 3342 , and a spring 3343 is sleeved on the outer side of the guide bracket 3342 .

[0079] Specifically, the connecting frame 321 is rotatably embedded in the No. 1 bracket 312 through the limiting shaft 322, the large gear 324 and the small gear 3312 are meshed with each other, one end of the No. 2 torsion spring 333 is embedded in the limiting ring 3314, and the other end of the No. 2 torsion spring 333 is embedded in the No. 1 bracket 312.

[0080] Specifically, the internal thread of the movable sleeve body 3321 is connected to the outer side of the threaded column 3313, the guide slider 3322 is slidably embedded in the guide rod 314, the guide bracket 3342 is slidably embedded in the outer bracket 3324, and the spring 3343 drives the inclined push block body 3341 away from the outer bracket 3324.

[0081] As can be seen from the above, when the trolley moves, the movable wheel 323 will drive the connecting frame 321 to rotate around the No. 1 bracket 312 through the limiting shaft 322. When the limiting shaft 322 rotates, the large gear 324 will also rotate. The rotation of the large gear 324 will cause the small gear 3312 to rotate. The rotation of the small gear 3312 will cause the driven rod 3311 to drive the threaded column 3313 to rotate. The rotation of the threaded column 3313 will cause the movable sleeve body 3321 to move upward along the guide rod 314 through the guide slider 3322. The upward movement of the movable sleeve body 3321 will cause the inclined push block body 3341 to move upward with it, thereby causing the movable plate body 221 to rotate and the rubber 223 to abut against the edge of the trolley to play a sealing role.

[0082] When the driven rod 3311 rotates, the limiting ring 3314 will also rotate, and the limiting ring 3314 will also cause the second torsion spring 333 to twist; when the trolley leaves, the second torsion spring 333 is reset, which will cause the limiting ring 3314 to drive the driven rod 3311 to reset, and the reset of the driven rod 3311 will cause the threaded column 3313 to drive the movable sleeve body 3321 to move downward, so that the inclined push block body 3341 automatically moves downward and separates from the movable plate body 221;

[0083] When the oblique push block body 3341 moves upward and causes the movable plate body 221 to rotate and rest against the edge of the trolley, while the oblique push block body 3341 is still moving upward, the oblique push block body 3341 will move along the outer bracket 3324 through the guide bracket 3342 and cause the spring 3343 to be compressed on the outer bracket 3324, thereby playing a buffering role.

[0084] When the movable plate body 221 rotates, the shaft rod 222 rotates around the shaft frame 212 and the No. 1 torsion spring 23 is twisted; when the trolley leaves, the No. 1 torsion spring 23 is reset to reset the movable plate body 221 and vertically downward again, which is convenient for next use.

[0088] Step 2: Sealing process

[0089] When the trolley enters the support frame area along the track, the movement of the trolley will push the driving wheel assembly to rotate on the mounting frame assembly; the rotation of the driving wheel assembly drives the movable kit in the push frame assembly to move upward along the guide rod through the gear transmission; the upward movement of the movable kit pushes the movable plate assembly to rotate through the push block, so that the rubber fits tightly to the edge of the trolley to achieve a sealing effect; at the same time, as the movable kit moves, the spring is compressed, which plays a buffering role and protects the sealing mechanism from impact;

[0090] Step 3: Sintering

[0091] After the sealing is completed, the gas injection assembly is started to transport gas to the gas injection rack through the gas pipe; the gas is sprayed out through the nozzle and ignited to sinter the materials in the trolley; during the sintering process, the sealing mechanism ensures that the gas in the trolley does not leak, ensuring the sintering efficiency and product quality;

10. A method for optimizing sealing of sintering machine parts, characterized in that: The sintering machine part sealing optimization device according to any one of claims 1 to 9 is used to complete the following steps: Step 1: Initial preparation Install the sintering machine part sealing optimization device at the designated position of the sintering machine, ensure that the supporting mechanism is firmly supported on the supporting frame of the sintering machine, and the gas injection assembly is reliably connected to the external gas source; Check and adjust the movable plate assembly of the sealing mechanism to ensure that it can rotate freely and reset under the action of the No. 1 torsion spring; Confirm that the contact between the driving wheel assembly of the driving mechanism and the trolley is good, and the push frame assembly can move smoothly driven by the driving wheel assembly; Step 2: Sealing process When the trolley enters the support frame area along the track, the movement of the trolley drives the drive wheel assembly to rotate on the mounting frame assembly; The rotation of the driving wheel assembly drives the movable set in the push frame assembly to move upward along the guide rod through the gear transmission; The upward movement of the movable kit drives the movable plate assembly to rotate through the push block, so that the rubber fits tightly to the edge of the trolley to achieve a sealing effect; At the same time, as the movable kit moves, the spring is compressed, playing a buffering role and protecting the sealing mechanism from impact; Step 3: Sintering After the sealing is completed, the gas injection assembly is started to deliver gas to the gas injection rack through the gas transmission pipe; The gas is sprayed out through the nozzle and ignited to sinter the materials in the trolley; During the sintering process, the sealing mechanism ensures that the gas in the trolley does not leak, thus ensuring the sintering efficiency and product quality; Step 4: Reset and wait When the trolley completes sintering and leaves the support frame area, the No. 2 torsion spring in the drive mechanism is reset, driving the push frame assembly and the movable kit to move downward; At the same time, the No. 1 torsion spring in the sealing mechanism is also reset, driving the movable plate assembly to rotate and reset, ready to welcome the arrival of the next car; The device enters standby mode, waiting for the start of the next round of sintering operation; Step 5: Maintenance and Inspection Regularly inspect and maintain the sealing optimization device of the sintering machine, including cleaning, lubrication and tightening; Check whether the rubber of the sealing mechanism is severely worn and replace it if necessary; Check whether the gears and bearings of the drive mechanism are worn or damaged, and repair or replace them in time if necessary.
