Description

Technical Field

[0001] The present application relates to the technical field of quicklime processing equipment, and in particular to a sintered quicklime flow stabilizing device. Background Art

[0002] During sintering production, quicklime is transported into the batching bin by compressed air. Since compressed air also enters the batching bin, the air pressure in the batching bin will increase. When the particle size and fluidity of quicklime change, it is easy to suspend the material in the sintering batching bin. After the material is suspended, the material suddenly collapses, which will cause the bin to be sprayed due to the increased air pressure, resulting in production loss caused by stopping the feeding of sintering. The sudden increase in the amount of quicklime will also cause fluctuations in the quality of the sintered ore. In addition, quicklime is corrosive and can easily burn the eyes and skin of the human body. Spraying the bin will cause safety problems and cause dust on site. At the same time, it needs to be manually cleaned up when it is sprayed on the ground, which increases the workload of the staff.

[0003] The existing patent (Announcement No.: CN219765230U) discloses a sintering quicklime flow stabilizing device, including a batching bin, the outlet of which is connected to a lower ash chute, a belt conveyor is provided below the lower ash chute, and a gate valve is installed on the lower ash chute. However, this technical solution still has shortcomings, as follows:

[0004] When the device is used, the quicklime entering the air suction pipe is filtered through the filter cartridge. However, when the filter cartridge is used for a long time, the quicklime is easily blocked continuously. Moreover, the filter cartridge is arranged in the air suction pipe, so it is troublesome to clean. Therefore, we propose a sintered quicklime flow stabilizing device to solve the above-mentioned problems.

[0005] Application Contents

[0006] The purpose of this section is to summarize some aspects of the embodiments of the present application and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and application title of the present application to avoid blurring the purpose of this section, specification abstract and application title, and such simplifications or omissions cannot be used to limit the scope of the present application.

[0007] Therefore, the purpose of this application is to provide a sintered quicklime flow stabilization device, which can solve the problem that when the existing device is used, the quicklime entering the suction pipe is filtered through a filter cartridge, but when the filter cartridge is used for a long time, it is easy to continuously clog the quicklime, and the filter cartridge is set in the suction pipe, so it is more troublesome to clean.

[0008] In order to solve the above technical problems, the present application provides a sintering quicklime flow stabilizing device, which adopts the following technical solution: comprising a flow stabilizing mechanism, which comprises a batching bin, a first exhaust pipe is arranged on the top of the batching bin, a second exhaust pipe is arranged on the side wall of the batching bin, and fans are arranged in the first exhaust pipe and the second exhaust pipe;

[0009] The scraping mechanism comprises a filter plate, which is fixedly arranged at one end where the first exhaust pipe and the second exhaust pipe are inserted into the batching bin, and a scraping member is movably arranged at one end of the filter plate facing the batching bin, and a movable plate is movably inserted in the scraping member.

[0010] By adopting the above technical scheme, this scheme first discharges the airflow in the batching bin through the cooperation of the fan and the first exhaust pipe, thereby causing the air pressure in the batching bin to remain in a negative pressure state, and filters and blocks the quicklime through the filter plate. When the fan is running, the movable plate moves under the action of wind force, and as the movable plate moves, it is easy to drive the scraping and sweeping member to move, thereby scraping the quicklime on the filter plate through the scraping and sweeping member.

[0011] Optionally, a plug-in valve for controlling the switch of the batching bin is movably connected to the side wall of the batching bin.

[0013] Optionally, a level meter is provided on the side wall of the batching bin, and a vibration motor is symmetrically provided on the outer wall of the batching bin.

[0014] By adopting the above technical solution, this solution facilitates detection of the drop opening of the batching bin through a level meter, thereby detecting whether the quicklime is discharged normally. When the quicklime is not discharged normally, the vibration motor is started to cause the batching bin to vibrate, thereby causing the quicklime to vibrate and fall.

[0015] Optionally, a rotating rod is rotatably arranged in the batching bin, and a plurality of stirring rods are arranged on the outer wall of the rotating rod along the circumference.

[0016] By adopting the above technical solution, the present invention facilitates the rotation of the stirring rod by the rotating rod, thereby facilitating the breaking of the quicklime in the batching bin by the stirring rod.

[0017] Optionally, one end of the rotating rod extends out of the batching bin and is inserted into the second exhaust pipe and is provided with a plurality of blades along the circumference, wherein the blades are at the outlet end of the second exhaust pipe.

[0018] By adopting the above technical solution, in this solution, when the second exhaust pipe discharges the airflow, the airflow drives the blades and the rotating rod to rotate, and then the rotating rod drives the stirring rod to rotate to break up the quicklime in the batching bin.

[0019] Optionally, the scraping member includes a circular tube, which is rotatably inserted into the filter plate, and one end of the circular tube extending out of the filter plate is provided with a plurality of scrapers along the circumference, the scrapers are slidably engaged with the outer wall of the filter plate, and a semicircular block is fixedly provided inside the circular tube.

[0020] By adopting the above technical solution, when the fan is started, the movable plate moves due to the force of wind, thereby driving the scraping member to rotate through the movable plate.

[0021] Optionally, the movable plate includes a guide rod, the guide rod passes through the round tube and is inserted into the second air guide tube and is fixedly provided with a disc, and the disc is connected to the filter plate by means of a spring.

[0022] By adopting the above technical solution, when the fan is started, the resistance between the disc and the airflow causes the disc to drive the guide rod to move and causes the spring to stretch and deform.

[0023] Optionally, the outer wall of the guide rod is provided with a spiral groove matched with the semicircular block, and the semicircular block is slidably matched with the inner wall of the spiral groove.

[0024] By adopting the above technical solution, when the disc drives the guide rod to move, the semicircular block slides along the inner wall of the spiral groove, thereby prompting the circular tube to drive the scraper to rotate.

[0025] In summary, the present application includes at least one of the following beneficial effects:

[0026] When the fan stops running, the movable plate loses its force. When the movable plate is reset, it drives the scraper to rotate again, so that the quicklime on the filter plate is scraped by the scraper, thereby reducing the possibility of the filter plate being blocked by quicklime and making it easier to clean the filter plate.

[0027] When the second exhaust pipe discharges the airflow, the airflow drives the blades and the rotating rod to rotate, and then the rotating rod drives the stirring rod to rotate to break up the quicklime in the batching bin. At the same time, the fan cooperates with the second exhaust pipe to keep a negative pressure state at the discharge port of the batching bin, so that the quicklime is adsorbed and falls.

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] Embodiment 1, refer to Figure 1-3 In this embodiment, in order to solve the problem that the quicklime entering the air suction pipe is filtered by the filter cartridge when the existing device is used, but the quicklime is easily blocked when the filter cartridge is used for a long time, and the filter cartridge is arranged in the air suction pipe, so it is troublesome to clean it, the application discloses a sintered quicklime flow stabilizing device,

[0036] The utility model comprises a flow stabilizing mechanism 100, which comprises a batching bin 101. A first exhaust pipe 102 is arranged on the top of the batching bin 101. The airflow in the batching bin 101 is discharged through the first exhaust pipe 102, so that the air pressure in the batching bin 101 is kept in a negative pressure state. When the suspended material collapses in the batching bin 101, the quicklime will reduce the power under the action of the negative pressure, so as to avoid the possibility of the bin being sprayed.

[0037] A second exhaust pipe 103 is provided on the side wall of the batching bin 101, and fans 104 are provided in the first exhaust pipe 102 and the second exhaust pipe 103. When quicklime does not fall normally, the fan 104 cooperates with the second exhaust pipe 103 to keep a negative pressure at the discharge port of the batching bin 101, thereby causing the quicklime to be adsorbed and fall.

[0038] The scraping mechanism 200 includes a filter plate 201, which is fixedly arranged at one end of the first exhaust pipe 102 and the second exhaust pipe 103 inserted into the batching bin 101. The airflow in the batching bin 101 is discharged through the cooperation of the fan 104 and the first exhaust pipe 102, thereby causing the air pressure in the batching bin 101 to maintain a negative pressure state, and the quicklime is filtered and blocked by the filter plate 201.

[0039] A scraping piece 202 is movably provided at one end of the filter plate 201 facing the batching bin 101, and a movable plate 203 is movably inserted in the scraping piece 202. The scraping piece 202 includes a circular tube 202a, which is rotatably inserted on the filter plate 201. One end of the circular tube 202a extending out of the filter plate 201 is provided with a plurality of scrapers 202b along the circumference. The scrapers 202b are slidably matched with the outer wall of the filter plate 201. A semicircular block 202c is fixedly provided in the circular tube 202a. When the fan 104 is started, the movable plate 203 is moved by the force of wind, thereby driving the scraping piece 202 to rotate through the movable plate 203. When the circular tube 202a drives the scraper 202b to rotate, the quicklime on the filter plate 201 is easily scraped through the scraper 202b.

[0040] The movable plate 203 includes a guide rod 203a, which passes through the circular tube 202a and is inserted into the second air guide tube and is fixed with a disc 203b. The disc 203b is connected to the filter plate 201 by setting a spring 203c. When the fan 104 is started, the resistance between the disc 203b and the airflow causes the disc 203b to move the guide rod 203a and causes the spring 203c to stretch and deform. When the fan 104 stops, the spring 203c facilitates the pulling of the disc 203b and the guide rod 203a to reset.

[0041] The outer wall of the guide rod 203a is provided with a spiral groove 203d that is compatible with the semicircular block 202c. The semicircular block 202c slides with the inner wall of the spiral groove 203d. When the disc 203b drives the guide rod 203a to move, the semicircular block 202c slides along the inner wall of the spiral groove 203d, thereby prompting the circular tube 202a to drive the scraper 202b to rotate, and the scraper 202b is used to facilitate scraping the quicklime on the filter plate 201.

[0042] The specific working principle is: first, the airflow in the batching bin 101 is discharged through the cooperation of the fan 104 and the first exhaust pipe 102, so that the air pressure in the batching bin 101 is kept in a negative pressure state, and the quicklime is filtered and blocked by the filter plate 201;

[0043] When the fan 104 is running, the movable plate 203 moves under the action of wind force, and the movable plate 203 moves to drive the scraper 202 to move, so that the quicklime on the filter plate 201 is scraped by the scraper 202, thereby reducing the possibility of the filter plate 201 being blocked by the quicklime;

[0044] When the fan 104 stops running, the movable plate 203 loses its acting force. When the movable plate 203 is reset, it drives the scraping member 202 to rotate again, so that the quicklime on the filter plate 201 is scraped by the scraping member 202 .

[0045] Example 2, refer to Figure 1-2 Based on the same concept as the first embodiment, the sintered quicklime flow stabilizing device further includes:

[0046] A plug-in valve 101a for controlling the opening and closing of the batching bin 101 is movably connected to the side wall of the batching bin 101. The plug-in valve 101a facilitates the operator to control the opening and closing of the batching bin 101.

[0047] A level meter 101b is provided on the side wall of the batching bin 101, and a vibration motor 101c is symmetrically provided on the outer wall of the batching bin 101. The level meter 101b is used to detect the material drop opening of the batching bin 101, so as to detect whether the quicklime is discharged normally. When the quicklime is not discharged normally, the vibration motor 101c is started to vibrate the batching bin 101, so as to cause the quicklime to vibrate and fall. At this time, when the level meter 101b still does not detect the quicklime discharge after twenty seconds, it indicates that the quicklime material in the batching bin 101 has fallen out.

[0048] The specific working principle is: the material level meter 101b is used to detect the material discharge port of the batching bin 101, so as to detect whether the quicklime is discharged normally;

[0049] When quicklime is not discharged normally, the vibration motor 101c is started to make the batching bin 101 vibrate, thereby making the quicklime vibrate and fall down, and at the same time, the blower 104 cooperates with the second exhaust pipe 103 to make the discharge port of the batching bin 101 maintain a negative pressure state, thereby making the quicklime be adsorbed and fall down;

[0050] At this time, when the material level meter 101b still does not detect the quicklime discharge after 20 seconds, it means that the quicklime material in the batching bin 101 has been exhausted, and the operator needs to replenish the quicklime.

[0051] Example 3, refer to Figure 1-2 Based on the same concept as the first embodiment, the sintered quicklime flow stabilizing device further includes:

[0052] A rotating rod 101d is rotatably arranged in the batching bin 101, and a plurality of stirring rods 101e are arranged along the circumference of the outer wall of the rotating rod 101d. The rotating rod 101d can easily drive the stirring rod 101e to rotate, so that the stirring rod 101e can easily break up the quicklime in the batching bin 101, thereby causing the quicklime to fall.

[0053] One end of the rotating rod 101d extends out of the batching bin 101 and is inserted into the second exhaust pipe 103 and is provided with a plurality of blades 101f along the circumference. The blades 101f are at the air outlet end of the second exhaust pipe 103. When the second exhaust pipe 103 discharges the airflow, the blades 101f and the rotating rod 101d are driven to rotate by the airflow, and then the stirring rod 101e is driven to rotate by the rotating rod 101d to break up the quicklime in the batching bin 101.

[0054] The specific working principle is: when the second exhaust pipe 103 discharges the airflow, the airflow drives the blades 101f and the rotating rod 101d to rotate, and then the rotating rod 101d drives the stirring rod 101e to rotate to break up the quicklime in the batching bin 101.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
