Description

Technical Field

[0001] The present invention relates to the technical field of coal blending coking, and specifically to a coal blending coking device capable of improving the thermal strength performance of coke. Background Art

[0002] As the name implies, coal blending coking is used to mix, pulverize, form, and coke different types of coal. Different coals have different characteristics. For example, gas coal has a high volatile content and poor caking property, fat coal has strong caking property, and coking coal can produce high-quality coke but has relatively less reserves. When blending coal, according to the quality requirements of the required coke, such as strength, particle size, etc., appropriate coal types are selected and their proportions are determined. Generally, multiple coals are mixed to comprehensively utilize the advantages of various coals.

[0003] Coal is usually stored in a coal blending bin, and there is a feeding device at the bottom of the coal blending bin, such as a disc feeder or a belt scale feeder. The disc feeder controls the coal discharge amount by adjusting the rotation speed of the disc, and the belt scale feeder can accurately control the feeding amount of each coal according to the set weight ratio.

[0004] After various coals are discharged from the coal blending bin according to the predetermined ratio, they are fully mixed in a belt conveyor or a mixer. The prepared coal is loaded into the carbonization chamber of the coke oven. There are mainly two coal charging methods for the coke oven: the top charging method and the stamping method. The top charging method is to load the coal from the top of the carbonization chamber, and this method is suitable for coal blending with conventional particle sizes. The stamping method is to first stamp the prepared coal into a coal cake and then load it from the side of the carbonization chamber. This method can increase the bulk density of the coal and improve the coke quality, especially suitable for coal materials with high volatile content and weak caking property.

[0005] For example, as mentioned in the patent with the publication number it is to improve the coal blending efficiency by constructing the overall coal blending and pulverizing the coal material during the coal blending process. However, considering the overall coking process, the connection between equipment is less, which still leads to an increase in the overall material transfer time and affects the overall coking efficiency.

[0006] Therefore, we propose a coal blending coking device capable of improving the thermal strength performance of coke. Summary of the Invention

[0007] The purpose of the present invention is to provide a coal blending coking device capable of improving the thermal strength performance of coke, so as to solve the problem in the above background art that the lack of effective simplification of the process equipment for coal blending coking leads to an insignificant improvement in the subsequent coking efficiency.

[0008] To achieve the above object, the present invention provides the following technical solution: A coal blending coking device capable of improving the thermal strength performance of coke, including a coal discharging box and a mixing box. The mixing box is installed at the bottom of the coal discharging box. At the bottom of the inner wall partition of the coal discharging box, an isolation flow channel is correspondingly and fixedly connected. The bottom of the isolation flow channel is fixedly connected to a temporary storage box. A guiding cylinder is installed on the opposite surface of the temporary storage box and the mixing box, and the guiding cylinder is connected to the mixing box in communication;

[0009] A transfer table is installed in the channel on the side of the mixing box. The side wall of the temporary storage box is movably connected with a transmission gear set through a bearing. A rack is slidably connected to the side of the temporary storage box. The bottom of the rack is fixedly connected with a tamping hammer through a bolt. The side tooth pattern of the rack is meshed with the fixed semi-gear on the transmission gear set.

[0010] Further, a clamping column is sleeved and movably connected to the rack. A quantitative feeding mechanism is installed on the top of the mixing box. The quantitative feeding mechanism includes a sliding rod and a limiting sleeve. The sliding rod is slidably connected to the top of the mixing box. The limiting sleeve is sleeved and movably connected to the sliding rod. The straight rod side of the limiting sleeve abuts against the channel on the clamping column.

[0011] Further, the quantitative feeding mechanism further includes a slider and a steering rod. The slider is slidably connected to the channel on the top of the sliding rod. A threaded screw is movably connected to the top of the sliding rod. One end of the threaded screw penetrates through the slider and is movably connected to the inner wall of the sliding rod.

[0012] Further, one side of the slider is movably connected to the steering rod. The groove on the steering rod is clamped with the protrusion on the outer wall of the limiting sleeve. The inner side of the sliding rod is fixedly connected with a rack through a bolt.

[0013] Further, a ratchet assembly is movably connected in the guiding cylinder. A coiling fan blade is fixedly connected to the ratchet assembly in the guiding cylinder. The rack on the sliding rod is meshed with the tooth sleeve on the outer wall of the ratchet assembly.

[0014] Further, a control box is fixedly installed on the top of the mixing box through a bolt. A discharge port is arranged on the mixing box on the side of the tamping hammer.

[0015] Further, a mixing chamber one and a mixing chamber two are arranged in the mixing box. The mixing chamber two is communicated with the discharge port. A coiling device is movably connected to the inner wall of the bottom of the mixing chamber one.

[0016] The coal blending coking method capable of improving the thermal strength performance of coke is as follows:

[0017] Coal blending ratio adjustment: The coal is put into the temporary storage bin according to the coal type. The coal type enters the temporary storage bin through the coal outlet bin and the isolation flow channel. The operator adjusts the quantitative feeding mechanism according to the mixing ratio of a single coal type. Rotate the threaded stud on the sliding rod, and use the rotation of the steering rod to drive the entire limit sleeve to rotate. Along with the rotation of the limit sleeve, adjust the position of the entire sliding rod on the side of the guiding cylinder. The rack contacts the ratchet assembly on the guiding cylinder, driving the coiling fan blade to rotate. At the same time, start the power mechanism in the temporary storage bin, causing the transmission gear set to rotate, driving the movement of the toothed rod connected to the entire tamping hammer, realizing the movement of the entire sliding rod. Along with the movement of the sliding rod realized by the single movement of the tamping hammer, the mass of the coal type falling in the guiding cylinder is recorded and measured. Mark the position of the slider according to the measurement record, providing an identification standard for the quantitative discharging of the temporary storage bin in the follow-up;

[0018] Mixing and tamping: Along with the repeated movement of the tamping hammer fixed to the toothed rod, the continuously discharged coal type enters the first mixing chamber in the mixing bin. The control box drives the coiling device to rotate in the reverse direction, and the coal type is continuously stirred and mixed in the first mixing chamber. After reaching the set mixing time, the coiling device rotates forward, pushing the mixed coal type into the second mixing chamber, and discharging it from the front discharge port of the second mixing chamber onto the transfer table. At the same time, the movement of the tamping hammer hammers the coal type, forming a coal cake and loading it from the side of the carbonization chamber for coking operations.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In the present invention, by simplifying the entire coal blending and coking device and using the coal tamping operation during the coking process, automatic feeding and mixing in the coal outlet bin are realized, simplifying the coking process. The quantitative feeding mechanism is driven by the movement of the toothed rod, controlling the movement of the rack on the side of the sliding rod, driving the rotation of the entire ratchet assembly, realizing the rotation of the coiling fan blade by a fixed number of turns, completing the quantitative discharging of the temporary storage bin. The position is adjusted by the slider installed on the sliding rod, and the steering of the entire limit sleeve can also be controlled. When the toothed rod moves, the feeding amount of the temporary storage bin can be automatically adjusted once, realizing the adjustment of different coal type blending. Compared with using a disk feeder or a belt scale feeder for coal type mixing, it has a higher adaptability to the entire coking equipment, is more convenient to use, and speeds up the entire coking process at the same time;

[0021] 2. In the present invention, to improve the mixing effect of the coal type after discharging, the installed mixing bin is used for timed stirring of the stored materials. During the stirring process, the mixed materials are continuously pushed onto the transfer table, and the moving tamping hammer is used for pounding to complete the production of the coal cake, facilitating the mixing movement. The coiling device moves in a forward and reverse rotation manner, which can not only realize the stirring of the coal material but also complete the subsequent automatic discharging, and has a high adaptability to the entire coal blending and coking device.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-7 , the present invention provides a technical solution:

[0032] Generally, various coals such as gas coal, fat coal, and coking coal are selected and blended in a certain proportion. Gas coal has a high volatile content and relatively weak caking property, but it can increase the lump size and porosity of coke, making the coke reactivity good. Fat coal has a strong caking property and can improve the coke strength. Coking coal can produce high-strength and low-crack quality coke. Reasonably matching these coal types can not only ensure the coke quality but also make full use of different coal resources and reduce costs. Coal is usually stored in the coal blending bin;

[0033] Generally, there is a feeding device at the bottom of the coal blending bin, such as a disk feeder or a belt scale feeder. The disk feeder controls the coal discharge amount by adjusting the rotation speed of the disk, while the belt scale feeder can accurately control the feeding amount of each coal according to the set weight ratio. To simplify the entire coal blending process and improve the coke thermal strength performance, while using the tamping hammer 12 to hammer the mixed coal, automatic discharging is carried out to accelerate the coking process;

[0034] Such as Figure 1 and Figure 2 As shown, the isolation flow channels 2 are installed at the bottom of the coal discharge box 1 according to the number of coal types in the coal blending. In the present invention, three coal types are proportioned in a single coal discharge box 1, and the isolation flow channels 2 are installed at its bottom. At the same time, the inner wall of the coal discharge box 1 is divided by a partition to sort the falling products, and finally they are uniformly dropped into the temporary storage box 3;

[0035] Among them, the entire coal blending and subsequent tamping are carried out simultaneously. However, after the coal blending step, during the tamping step of the coal types, after mixing, it causes the equipment to perform air compression for a period of time after starting. As Figure 3 and Figure 4 shown, a transmission gear set 14 is movably connected to one side of the temporary storage box 3, and a rack 11 is slidably connected to the side of the transmission gear set 14. The tamping hammer 12 is installed at the bottom of the rack 11. The entire transmission gear set 14 is driven by a driving component to rotate, raising the height of the tamping hammer 12 at the end of the rack 11. At the same time, the entire transmission gear set 14 is divided into a full gear and a half gear, and the tooth pattern on the side of the rack 11 corresponds to the half gear;

[0036] When the half gear rotates to drive the entire rack 11 to rise, the half gear in the rotation process disengages from the abutment against the tamping hammer 12 connected to the rack 11, causing the overall tamping hammer 12 to descend and stamp the mixed coal stored on the transfer table 6, increasing the bulk density of the coal and improving the subsequent coke quality;

[0037] For the drive of the rack 11, a clamping column 13 is also movably connected to the rack 11. A quantitative feeding mechanism 15 is installed on the corresponding side of the guide cylinder 4 at the top of the mixing box 5. While using the driving mechanism to raise the tamping hammer 12, the movement of the quantitative feeding mechanism 15 is completed to control the quantitative feeding of the coal stored in the temporary storage box 3. Specifically, during operation, as Figure 4 shown, when the entire rack 11 moves upward, due to the limitation of the clamping column 13, the limit sleeve 155 installed on the side of the sliding rod 151 drives the overall sliding rod 151 to slide to the right. At this time, the rack 154 installed on the side of the sliding rod 151 starts to contact the ratchet assembly 17 in the guide cylinder 4;

[0038] Such as Figure 5As shown, the entire ratchet assembly 17 is composed of a tooth sleeve on the outer ring and a triangular support ring on the inner ring. When the entire tooth bar 11 moves upward, it drives the entire ratchet assembly 17 to rotate. At this time, the rotation of the outer ring tooth sleeve can cause the rotation of the inner ring triangular support ring, thereby driving the coiling fan blade 18 installed on the triangular support ring to rotate. The rotation of the entire coiling fan blade 18 realizes the falling of the coal types placed in the temporary storage box 3. The greater the rotation amplitude of the ratchet assembly 17, the greater the mass of the coal types that the coiling fan blade 18 can discharge. Thus, the quantitative discharging of the entire temporary storage box 3 is achieved by controlling the moving distance of the slide bar 151;

[0039] When the entire tooth bar 11 moves downward, the slide bar 151 moves in the reverse direction at this time. The outer ring tooth sleeve on the ratchet assembly 17 cannot drive the inner ring triangular support ring to rotate at this time. The coiling fan blade 18 remains stationary at this time. For the adjustment of the moving distance of the slide bar 151 each time, a slider 152 is slidably connected in the top channel of the entire slide bar 151. A threaded stud 153 movably connected to the slide bar 151 is threadedly connected to the slider 152;

[0040] By manually adjusting the rotation of the threaded rotation, the height of the entire slider 152 on the slide bar 151 is controlled. For the movement of the slider 152, the steering rod 156 installed on one side thereof will drive the entire limit sleeve 155 to rotate. Due to the angle change of the entire latch 13, along with the rotation of the limit sleeve 155, the distance of the entire slide bar 151 will also change. Taking the angle between the horizontal plane and the limit sleeve 155 as an example;

[0041] When the entire slider 152 moves downward, while the steering rod 156 moves, it pushes the entire limit sleeve 155 clamped at one end to rotate. At this time, the angle between the side of the limit sleeve 155 and the horizontal plane decreases. The sliding distance of the entire slide bar 151 caused by the up and down movement of the tooth bar 11 each time increases, which also leads to an increase in the rotation amplitude of the ratchet assembly 17 and an increase in the discharge amount each time. On the contrary, when the entire slider 152 moves upward, the angle between the entire limit sleeves 155 increases, and the moving distance of the slide bar 151 realized by the single movement of the tooth bar 11 decreases;

[0042] By controlling the height of the slider 152 on the slide bar 151, and at the same time using the steering rod 156 to drive the entire limit sleeve 155 to rotate, controlling the change in the displacement distance of the slide bar 151 caused by the movement of the latch 13 on the side of the tooth bar 11, and cooperating with the rotation of the ratchet assembly 17 to complete the quantitative discharging of the coal types in the temporary storage box 3. Compared with using a dedicated disk feeder or a belt scale feeder, the coal type batching process is simplified;

[0043] For the coal types during the blanking process, they are mixed to facilitate subsequent extrusion forming. A mixing box 5 is connected to the bottom of the guiding cylinder 4. A first mixing chamber 8 and a second mixing chamber 10 are provided inside the entire mixing box 5. All types of coal falling from the top uniformly fall into the first mixing chamber 8. A coiler 9 is installed on the mixing box 5. At the connection position between the first mixing chamber 8 and the second mixing chamber 10, the coiler 9 is controlled by a regulating box 16 to rotate.

[0044] When the coal blending coking device that can improve the coke thermal strength performance is in use, first, air pressure blanking is carried out. After the quantitative feeding mechanism 15 at the bottom of a single coal discharging box 1 is adjusted, the driving component is started to drive the transmission gear group 14 to rotate in one direction. The continuously moving transmission gear group 14 drives the rack 11 to move up and down, realizing the air pressure work of the tamping hammer 12. At the same time, coal types continuously enter the mixing box 5 along the guiding cylinder 4. At this time, the regulating box 16 drives the coiler 9 to rotate in the reverse direction to stir and mix the incoming coal material. Due to the opposite rotation directions, the coal material cannot be discharged into the second mixing chamber 10.

[0045] After reaching the set mixing time, at this time, the coiler 9 rotates forward, continuously pushing the mixed coal material into the second mixing chamber 10. Finally, it rolls down along the section of the second mixing chamber 10 to the side of the discharge port 7 and enters the top of the transfer table 6 along the discharge port 7. Along with the movement of the transfer table 6, the continuously incoming mixed material contacts the descending tamping hammer 12 and is tamped into a coal cake, and then is loaded from the side of the carbonization chamber to complete the subsequent coking operation.

[0046] The working principle of the present invention:

[0047] The coal types enter the temporary storage box 3 through the coal discharging box 1 and the isolation flow channel 2 for storage. The operator adjusts the quantitative feeding mechanism 15 according to the mixing ratio of a single coal type. Rotate the threaded stud 153 on the sliding rod 151, and use the rotation of the steering rod 156 to drive the entire limiting sleeve 155 to rotate. Along with the rotation of the limiting sleeve 155, the position of the entire sliding rod 151 on the side of the guiding cylinder 4 is adjusted. The rack 154 contacts the ratchet assembly 17 on the guiding cylinder 4, driving the coiling fan blade 18 to rotate. At the same time, the power mechanism in the temporary storage box 3 is started, enabling the transmission gear group 14 to rotate, driving the rack 11 connected to the entire tamping hammer 12 to move, realizing the movement of the entire sliding rod 151. Along with the movement of the sliding rod 151 realized by the single movement of the tamping hammer 12, the coal types falling in the guiding cylinder 4 enter the mixing box 5.

[0048] With the repeated movement of the tamping hammer 12 fixed to the toothed rod 11, the coal continuously discharged enters the first mixing chamber 8 in the mixing box 5. The control box 16 drives the coiler 9 to rotate in the reverse direction, and the coal is continuously stirred and mixed in the first mixing chamber 8. After reaching the set mixing time, the coiler 9 rotates forward, pushing the mixed coal into the second mixing chamber 10, and discharging it from the front discharge port 7 of the second mixing chamber 10 onto the transfer table 6. At the same time, the movement of the tamping hammer 12 hammers the coal to form a coal cake, which is then loaded from the side of the carbonization chamber for coking operation.
