Description

Technical Field

[0001] This utility model relates to the field of coke oven equipment technology, and in particular to a coal cake compaction device for coke ovens. Background Technology

[0002] Coke production utilizes coke oven equipment. During coke production, loose coal needs to be compacted to form coal cakes, typically using a coal cake compacting device. Commonly available coal cake compacting devices include a coal box and a compacting trolley with a compacting mechanism. The coal box consists of a coal support plate, a fixed baffle, a rear baffle, a left baffle, and a right baffle, forming an open-top rectangular box structure. The fixed baffle is fixed to a base, the coal support plate is mounted on the base via a back-and-forth moving structure, and the rear baffle is located at the rear end of the coal support plate. The compacting trolley with the compacting mechanism moves across the top of the coal box via a moving platform. During operation, the compacting mechanism compacts the loose coal within the coal box. During the tamping process, the tamping hammer is driven upward by a power device, and then automatically falls down using the weight of the tamping hammer to tamp the loose coal. Since the tamping hammer is relatively long in the vertical direction, there will be some swaying during the up-and-down movement of the tamping hammer. In order to avoid collisions between the tamping hammers, a certain distance must be left between each tamping hammer. However, the existing tamping hammer can only move in the vertical direction and cannot move in the horizontal direction. Therefore, the position of each tamping hammer hitting the coal cake remains unchanged. Furthermore, because a certain distance is left between each tamping hammer, the area between two tamping hammers cannot be tamped, resulting in poor uniformity of coal cake tamping. Utility Model Content

[0003] The purpose of this invention is to provide a coal cake compaction device for coke ovens in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A coal briquettes tamping device for coke ovens includes a coal box and a drive mechanism, as well as a mounting plate. Support plates are fixedly connected to both sides of the mounting plate, and the support plates are fixedly connected to the drive mechanism. Multiple tamping rods are arranged parallel to each other in the left-right direction inside the mounting plate. The drive mechanism is used to drive the tamping rods to move upward. Tamping blocks are slidably connected to the bottom of the tamping rods in the left-right direction. The tamping blocks are located inside the coal box. A telescopic rod is fixedly connected to the top of the tamping blocks. A slider is fixedly connected to the top of the telescopic rod. The slider is slidably connected to the mounting plate. An adjustment mechanism is provided on the mounting plate for simultaneously driving the movement of multiple sliders.

[0006] Preferably, the adjustment mechanism includes a bracket, which is fixedly connected to the drive mechanism. A motor is fixedly connected to the bracket, and a lead screw is fixedly connected to the output shaft of the motor. Multiple threaded blocks are threadedly connected to the lead screw, and the number of threaded blocks is the same as the number of sliders. Each threaded block is fixedly connected to each slider. Bearing seats are rotatably connected to both ends of the lead screw, and the bearing seats are fixedly connected to both sides of the mounting plate.

[0007] Preferably, the bottom of the tamping block is provided with a groove, and the bottom end of the tamping rod is slidably connected in the groove.

[0008] Preferably, the chute passes through the tamping block in the left-right direction, and the front and rear inner walls of the chute are fixedly connected with matching protrusions. The two sides of the matching protrusions are flush with the two sides of the tamping block. The front and rear sides of the bottom end of the tamping rod are provided with matching grooves, and the matching grooves slide with the matching protrusions.

[0009] Preferably, steel balls are movably embedded in the inner wall of the groove, and the steel balls are in contact with the groove.

[0010] Preferably, the mounting plate has multiple through holes through which the tamping rod passes. The through holes have through grooves extending in the left and right directions, and the slider slides in the through grooves.

[0011] The beneficial effects are as follows: the tamping rod and tamping block are designed separately. The tamping block can move left and right at the bottom of the tamping rod. Multiple sliders are moved simultaneously through the adjustment mechanism. The sliders drive the tamping block to move through the telescopic rod. The left and right positions of the tamping block are adjusted in a uniform manner, thereby changing the position of the tamping block when it strikes the coal cake. This allows the tamping block to strike various areas on the top surface of the coal cake, thereby improving the uniformity of tamping, improving the quality of the coal cake, and reducing the occurrence of coal cake collapse.

Therefore, they cannot be understood as limitations on the present invention.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] like Figures 1-6As shown, a coke oven coal briquettes tamping device includes a coal box 1 and a drive mechanism 2, as well as a mounting plate 3. Support plates 4 are welded to both sides of the mounting plate 3 and are fixedly connected to the drive mechanism 2. Multiple tamping rods 5 arranged parallel to each other in the left-right direction are disposed within the mounting plate 3. The drive mechanism 2 drives the tamping rods 5 upwards. Existing technology can be used for the drive mechanism 2, which will not be elaborated here. Tamping blocks 6 are slidably connected to the bottom of the tamping rods 5 in the left-right direction. The tamping blocks 6 are located inside the coal box 1. Loose coal is added to the coal box 1, and the drive mechanism 2 drives the tamping rods 5 and tamping blocks 6 upwards. Then, the tamping rods 5 and tamping blocks 6 automatically fall under their own weight, causing the tamping blocks 6 to hammer the loose coal in the coal box 1 into briquettes. The top of the coal cake and tamping block 6 is fixedly connected to a telescopic rod 7. The telescopic rod 7 is a telescopic structure composed of multiple sleeves. The telescopic rod 7 is used to extend and guide, ensuring that the tamping rod 5 and the tamping block 6 can move up and down while improving the stability of the tamping rod 5's up and down movement. The top of the telescopic rod 7 is fixedly connected to a slider 8, which is slidably connected to the mounting plate 3. The mounting plate 3 is equipped with an adjustment mechanism 9 for simultaneously driving the movement of multiple sliders 8. By adjusting the left and right positions of the sliders 8 through the adjustment mechanism 9, the sliders 8 drive the telescopic rod 7 to move left and right, and the telescopic rod 7 drives the tamping block 6 to move left and right, thereby adjusting the left and right positions of the tamping block 6 so that the tamping block 6 can fully tamp all positions on the top surface of the coal cake.

[0025] The adjustment mechanism 9 includes a bracket 901, which is connected to the drive mechanism 2 by screws. A motor 902 is bolted to the bracket 901. The output shaft of the motor 902 is connected to a lead screw 903 via a coupling. Multiple threaded blocks 904 are threadedly connected to the lead screw 903. The number of threaded blocks 904 is the same as that of the sliders 8. Each threaded block 904 is fixedly connected to each slider 8. Bearing seats 905 are rotatably connected to both ends of the lead screw 903. The bearing seats 905 are fixedly connected to both sides of the mounting plate 3. The motor 902 drives the lead screw 903 to rotate, and the lead screw 903 drives all the threaded blocks 904 to move synchronously, thereby making all the sliders 8 move synchronously.

[0026] The bottom of the tamping block 6 is provided with a groove 601. The bottom end of the tamping rod 5 is slidably connected in the groove 601. The groove 601 passes through the tamping block 6 in the left and right direction. The front and rear inner walls of the groove 601 are fixedly connected with mating protrusions 602. The two sides of the mating protrusions 602 are flush with the two sides of the tamping block 6. The front and rear sides of the bottom end of the tamping rod 5 are provided with mating grooves 501. The mating grooves 501 and the mating protrusions 602 are slidably engaged. With this configuration, when loose coal enters the groove 601, the relative movement of the tamping block 6 and the tamping rod 5 can push the loose coal out of the groove 601, avoiding the accumulation of loose coal in the groove 601 and affecting the movement of the tamping block 6.

[0027] Steel balls 502 are movably embedded in the inner wall of the groove 501. The steel balls 502 contact the slide groove 601. The steel balls 502 can reduce the friction between the tamping rod 5 and the tamping block 6, making the movement of the tamping block 6 more stable and smooth.

[0028] The mounting plate 3 has multiple through holes 301, through which the tamping rod 5 passes. The through holes 301 can guide the tamping rod 5 and improve the stability of the up and down movement of the tamping rod 5. The through holes 301 have through grooves 302 extending in the left and right direction, and the slider 8 slides in the through grooves 302.

[0029] Working principle: During use, loose coal is poured into coal box 1. The driving mechanism 2 drives the tamping rod 5 to move upward, which in turn drives the tamping block 6 to move upward. Then, the tamping rod 5 and the tamping block 6 fall automatically under their own weight. The tamping block 6 tamps the loose coal in coal box 1 to form a coal cake. During the tamping process, the motor 902 drives the lead screw 903 to rotate. The lead screw 903 drives the threaded block 904 to move left and right. The threaded block 904 drives the slider 8 to move. The slider 8 drives the telescopic rod 7 to move. The telescopic rod 7 drives the tamping block 6 to move, thereby adjusting the left and right position of the tamping block 6 so that the tamping block 6 can fully tamp all areas of the top surface of the coal cake, making the coal cake tamped more evenly.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
