Description

Technical Field

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

[0002] Coal blending for coking, as the name implies, is used to mix, crush, shape and coke different types of coal. Different types of coal have different characteristics. For example, gas coal has high volatility and poor cohesiveness, while fat coal has strong cohesiveness. Coking coal can produce high-quality coke, but its reserves are relatively small. When blending coal, according to the quality requirements of the required coke, such as strength, particle size, etc., the appropriate coal type is selected and its proportion is determined. Generally, multiple types of coal are mixed to comprehensively utilize the advantages of various coals.

[0003] Coal is usually stored in a coal bunker with a feeding device at the bottom, such as a disc feeder or a belt scale feeder. The disc feeder controls the amount of coal fed by adjusting the speed of the disc, while the belt scale feeder can accurately control the feeding amount of each type of 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 the belt conveyor or mixer, and the blended coal is loaded into the carbonization chamber of the coke oven. There are two main coal loading methods for the coke oven: top loading and tamping. The top loading method is to load the coal from the top of the carbonization chamber. This method is suitable for coal blending of conventional particle size, while the tamping method is to tamp the blended coal into coal cakes first, and then load it from the side of the carbonization chamber. This method can increase the bulk density of coal and improve the quality of coke, and is especially suitable for coal with high volatile matter and weak cohesion.

[0005] If the publication number is The patent mentions that the efficiency of coal blending is improved by constructing a whole coal blending system and crushing the coal during the coal blending process. However, considering the overall coking process, there is less connection between equipment, which will still increase the overall time of material transfer and affect the overall efficiency of coking.

[0006] Therefore, we propose a coal blending coking device which can improve the thermal strength performance of coke. Summary of the invention

[0015] Furthermore, a mixing chamber 1 and a mixing chamber 2 are provided in the mixing box, the mixing chamber 2 is communicated with the discharge port, and a coiler is movably connected to the inner wall of the bottom of the mixing chamber 1.

[0016] The coal blending coking method that can improve the thermal strength performance of coke is:

[0017] Coal blending ratio adjustment: The temporary storage box is placed according to the type of coal. The coal types flow out of the coal box and the isolation flow channel and enter the temporary storage box for storage. The operator adjusts the quantitative material feeding mechanism according to the mixing ratio of a single type of coal, rotates the threaded rotary column on the slide bar, and uses the rotation of the steering rod to drive the entire limit sleeve to rotate. The position of the entire slide bar on the guide cylinder side is adjusted along with the rotation of the limit sleeve. The rack contacts the ratchet assembly on the guide cylinder, driving the coiling fan blade to rotate, and at the same time, the power mechanism located in the temporary storage box is started, so that the transmission gear group rotates, driving the gear rod connected to the entire tamping hammer to move, realizing the movement of the entire slide bar.

At the same time, the tamping hammer hammers the coal to form coal cakes, which are then loaded from the side of the carbonization chamber for coking operations.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1.

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-7 , the present invention provides a technical solution:

[0032] Usually, gas coal, fat coal, coking coal and other types of coal are selected and blended in a certain proportion. Gas coal has high volatile matter and relatively weak bonding, but it can increase the size and porosity of coke, making the coke more reactive. Fat coal has strong bonding and can improve the strength of coke. Coking coal can produce high-strength, low-crack high-quality coke. Reasonable matching of these types of coal can not only ensure the quality of coke, but also make full use of different coal resources and reduce costs. Coal is usually stored in coal blending bunkers;

[0033] Usually, there is a feeding device at the bottom of the coal batching bin, such as a disc feeder or a belt scale feeder. The disc feeder controls the amount of coal fed by adjusting the rotation speed of the disc, and the belt scale feeder can accurately control the feeding amount of each type of coal according to the set weight ratio. In order to simplify the entire coal batching process and improve the thermal strength performance of coke, the tamping hammer 12 is used to hammer the mixed coal and automatically discharge the material at the same time, thereby accelerating the coking process;

[0034] like Figure 1 and Figure 2 As shown, the isolation flow channel 2 at the bottom of the coal outlet box 1 is installed according to the number of coal types to be blended. The present invention uses a single coal outlet box 1 to blend three types of coal, and an isolation flow channel 2 is installed at its bottom. At the same time, the inner wall of the coal outlet box 1 uses a partition as a dividing line to sort the falling products, and finally they fall uniformly into the temporary storage box 3;

[0035] Among them, the entire coal blending and subsequent tamping are carried out simultaneously, but the coal tamping step is after the mixing, resulting in a period of air compression after the equipment is turned on, such as Figure 3 and Figure 4 As shown, a transmission gear set 14 is movably connected to one side of the temporary storage box 3, and a gear rod 11 is slidably connected to the side of the transmission gear set 14. A tamping hammer 12 is installed at the bottom of the gear rod 11. The driving assembly drives the entire transmission gear set 14 to rotate, and the tamping hammer 12 at the end of the gear rod 11 is raised. At the same time, the entire transmission gear set 14 is divided into a full gear and a half gear, and the side tooth pattern of the gear rod 11 corresponds to the half gear.

[0036] When the half gear rotates and drives the entire gear rod 11 to rise, the half gear in the rotating process disengages from the tamping hammer 12 connected to the gear rod 11, causing the tamping hammer 12 to drop as a whole and press the mixed coal stored on the material transfer platform 6, thereby increasing the bulk density of the coal and improving the subsequent coke quality;

[0037] For the drive of the toothed rod 11, a clamping column 13 is movably connected to the toothed rod 11, and a quantitative material-dispensing mechanism 15 is installed on the corresponding side of the guide cylinder 4 at the top of the mixing box 5. The quantitative material-dispensing mechanism 15 is moved while the tamping hammer 12 is lifted by the driving mechanism to control the quantitative discharge of the coal stored in the temporary storage box 3. In specific operation, Figure 4 As shown, when the entire gear rod 11 moves upward, due to the limitation of the clamping column 13, the limiting sleeve 155 installed on the side of the slide rod 151 drives the entire slide rod 151 to slide to the right, and at this time, the rack 154 installed on the side of the slide rod 151 begins to contact the ratchet assembly 17 in the guide cylinder 4;

[0038] like Figure 5As shown, the entire ratchet assembly 17 is composed of an outer ring gear sleeve and an inner ring triangular support ring. When the entire gear rod 11 moves upward to drive the entire ratchet assembly 17 to rotate, the rotation of the outer ring gear sleeve can realize the rotation of the inner ring triangular support ring, thereby driving the coil fan blade 18 installed on the triangular support ring to rotate, and the rotation of the entire coil fan blade 18 realizes the fall of the coal placed in the temporary storage box 3. The greater the rotation amplitude of the ratchet assembly 17, the greater the mass of the coal that can be discharged by the coil fan blade 18, and the quantitative discharge of the entire temporary storage box 3 is realized by controlling the moving distance of the slide bar 151.

[0039] When the entire gear rod 11 moves downward, the slide bar 151 moves in the opposite direction, and the outer ring gear sleeve on the ratchet assembly 17 cannot drive the inner ring triangular support ring to rotate. The coil fan blade 18 remains stationary. For the adjustment of the single movement distance of the slide bar 151, a slide block 152 is slidably connected in the top groove of the entire slide bar 151, and a threaded rotating column 153 movably connected on the slide bar 151 is threadedly connected to the slide block 152;

[0040] The height of the entire slider 152 on the slide bar 151 is controlled by manually adjusting the rotation of the thread. When the slider 152 moves, the steering rod 156 installed on one side thereof will drive the entire limiting sleeve 155 to rotate. As the angle of the entire clamping column 13 changes, the distance of the entire slide bar 151 will also change with the rotation of the limiting sleeve 155. Take the angle between the horizontal plane and the limiting sleeve 155 as an example.

[0041] When the entire slider 152 moves downward, the steering rod 156 moves and pushes the entire limiting sleeve 155 clamped at one end to rotate. At this time, the angle between the limiting sleeve 155 and the horizontal plane decreases, and the sliding distance of the entire slide bar 151 caused by the single up and down movement of the gear rod 11 increases, which also causes the rotation amplitude of the ratchet assembly 17 to increase, and the single discharge amount increases. On the contrary, when the entire slider 152 moves upward, the angle between the entire limiting sleeve 155 increases, and the moving distance of the slide bar 151 achieved by the single movement of the gear rod 11 decreases.

[0042] By controlling the height of the slider 152 on the slide bar 151, and using the steering rod 156 to drive the entire limiting sleeve 155 to rotate, the displacement distance of the slide bar 151 caused by the movement of the side clamping column 13 of the control gear rod 11 is changed, and the quantitative discharge of the coal in the temporary storage box 3 is completed in coordination with the rotation of the upper ratchet assembly 17. Compared with the use of a dedicated disc feeder or a belt scale feeder, the coal batching process is simplified;

[0043] In order to mix the coal types in the feeding process and facilitate the subsequent extrusion forming, a mixing box 5 is connected to the bottom of the guide cylinder 4. A mixing chamber 1 8 and a mixing chamber 2 10 are provided in the entire mixing box 5. Various types of coal falling from the top fall into the mixing chamber 1 8 uniformly. A coiler 9 is installed in the mixing box 5, which is located at the connection position of the mixing chamber 1 8 and the mixing chamber 2 10. The coiler 9 is controlled to rotate by the control box 16.

[0044] When the coal blending coking device capable of improving the thermal strength performance of coke is used, air compression discharge is first performed. After the quantitative material-dispensing mechanism 15 at the bottom of the single-group coal outlet box 1 is adjusted, the driving assembly is started to drive the transmission gear set 14 to rotate in one direction. The continuously moving transmission gear set 14 drives the gear rod 11 to move up and down, so as to realize the air compression work of the tamping hammer 12. At the same time, coal types are continuously fed into the mixing box 5 along the guide cylinder 4. At this time, the regulating box 16 drives the coiler 9 to rotate in the opposite direction to stir and mix the coal materials that have entered. Since the rotation direction is opposite, the coal materials cannot be discharged into the mixing chamber 2 10.

[0045] After reaching the set mixing time, the coiler 9 now rotates forward, continuously pushing the mixed coal into the mixing chamber 2 10, and finally rolling down to the side of the discharge port 7 along the cross-section of the mixing chamber 2 10, and entering the top of the material transfer platform 6 along the discharge port 7. With the movement of the material transfer platform 6, the mixed material continuously contacts the descending tamping hammer 12 and is tamped into coal cakes, and then loaded into the side of the carbonization chamber to complete the subsequent coking operation.

[0046] Working principle of the present invention:

[0047] The coals are discharged from the coal box 1 and the isolation flow channel 2 and are stored in the temporary storage box 3. The operator adjusts the quantitative material-dispensing mechanism 15 according to the mixing ratio of the single coal type, rotates the threaded screw column 153 on the slide bar 151, and uses the rotation of the steering rod 156 to drive the entire limiting sleeve 155 to rotate. With the rotation of the limiting sleeve 155, the position of the entire slide bar 151 on the side of the guide cylinder 4 is adjusted. The rack 154 contacts the ratchet assembly 17 on the guide cylinder 4, driving the coiling fan blade 18 to rotate, and at the same time starting the power mechanism in the temporary storage box 3, so that the transmission gear group 14 rotates, driving the gear rod 11 connected to the entire tamping hammer 12 to move, so as to realize the movement of the entire slide bar 151. With the movement of the slide bar 151 realized by the single activity of the tamping hammer 12, the coal types falling in the guide cylinder 4 enter the mixing box 5;

[0048] The tamping hammer 12 fixed with the tooth rod 11 repeats the movement, and the continuously discharged coal enters the mixing chamber 8 in the mixing box 5. The regulating box 16 drives the coiler 9 to rotate in the opposite direction, and the coal is continuously stirred and mixed in the mixing chamber 8. After reaching the set mixing time, the coiler 9 rotates forward to push the mixed coal into the mixing chamber 2 10, and discharges it from the front end discharge port 7 of the mixing chamber 2 10 onto the material transfer platform 6. At the same time, the tamping hammer 12 hammers the coal to form coal cakes, which are then loaded from the side of the carbonization chamber for coking operations.
