Description

Technical Field

[0001] The utility model relates to a floating coal compaction device for the upper surface of a coal cake in a horizontal coke oven, belonging to the technical field of coke oven equipment. Background Art

[0002] At present, there is floating coal on the upper surface of the coal cake after being tamped by a tamping hammer. During the high-temperature dry distillation process in the carbonization chamber, the floating coal is easily completely burned, which is abbreviated as "coking", and finally results in a reduction in coke production. Content of the Utility Model

[0003] In order to solve the technical problems existing in the prior art, the utility model provides a floating coal compaction device for the upper surface of a coal cake in a horizontal coke oven, which can compact the floating coal.

[0004] To achieve the above object, the technical solution adopted by the utility model is a floating coal compaction device for the upper surface of a coal cake in a horizontal coke oven, including a coal pressing main beam installed on a coal cake groove. A guiding component is installed in the middle of the coal pressing main beam, and control oil cylinders are installed on both sides of the coal pressing main beam. The bottom of the guiding component and the bottom of the piston rod of the control oil cylinder are both installed on a coal pressing head. The coal pressing head is horizontally arranged and has the same width as the coal cake groove. The coal pressing head is a hollow structure, and a vibration component is installed inside. The vibration component includes a support seat installed in the coal pressing head and a rotating shaft installed on the support seat. An eccentric counterweight block and a semi-circular gear are installed on the rotating shaft. The semi-circular gear and the eccentric counterweight block are arranged vertically. A fixed rack is installed on the coal pressing main beam. The fixed rack extends to the inside through a through hole on the coal pressing head, and the fixed rack is used to mesh with the semi-circular gear.

[0005] Preferably, the guiding component includes a through hole provided on the coal pressing main beam, a guiding column installed in the through hole, and right-angle fixing seats installed at the four corners of the upper and lower parts of the through hole. Wear-resistant blocks are installed on the right-angle fixing seats, and the wear-resistant blocks are in contact with the guiding column.

[0006] Preferably, the maximum meshing length of the fixed rack and the semi-circular gear is not greater than 1 / 2 of the tooth length of the semi-circular gear.

[0007] Compared with the prior art, the utility model has the following technical effects: The utility model is used in cooperation with a tamping machine. After the tamping machine finishes tamping, the coal pressing head is controlled by a hydraulic oil cylinder to compact the floating coal for the second time, which can avoid coking of the floating coal in the carbonization chamber and increase coke production. At the same time, when the coal pressing head moves up and down, it can drive the eccentric counterweight block of the vibration component to swing left and right, thereby further improving the compaction quality of the floating coal and enhancing the compaction effect.

[0011] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0012] As Figures 1 to 3 shown, a floating coal compaction device for the upper surface of a coal cake in a horizontal coke oven includes a coal pressing main beam 1 installed on a coal cake trough. A guiding component 2 is installed in the middle of the coal pressing main beam 1. Control oil cylinders 3 are installed on both sides of the coal pressing main beam 1. The bottom of the guiding component 2 and the bottom of the piston rod of the control oil cylinder 3 are both installed on a coal pressing head 4. The coal pressing head 4 is horizontally arranged and has the same width as the coal cake trough. The coal pressing head 4 is a hollow structure, and a vibration component 5 is installed inside; the vibration component 5 includes a support seat 6 installed in the coal pressing head and a rotating shaft 7 installed on the support seat. An eccentric counterweight block 8 and a semi-circular gear 9 are installed on the rotating shaft 7. The semi-circular gear 9 and the eccentric counterweight block 8 are arranged vertically. A fixed rack 10 is installed on the coal pressing main beam 1. The fixed rack 10 extends to the inside through a through hole on the coal pressing head 4, and the fixed rack 10 is used to mesh with the semi-circular gear 9.

[0013] The floating coal compaction device for the upper surface of a coal cake in the present utility model is used in cooperation with a tamping machine. After the tamping machine finishes tamping, the present device is used to compact the floating coal for the second time to ensure that the floating coal can be completely compacted. When in use, after tamping, the hydraulic oil cylinder 3 controls the coal pressing head 4 to move downward to compact the floating coal in the coal cake trough in sequence. During this process, the vibration component 5 in the coal pressing head 4 can generate vibration to further extrude the floating coal. The vibration component 5 adopts an eccentric counterweight block 8 and a semi-circular gear 9. When the coal pressing head rises, after the coal pressing head 4 rises a certain distance, the fixed rack 10 meshes with the semi-circular gear 9. The fixed rack 10 controls the semi-circular gear 9 to rotate, and then controls the eccentric counterweight block 8 to rotate upward. The maximum meshing length of the fixed rack 10 and the semi-circular gear 9 is not greater than 1 / 2 of the tooth length of the semi-circular gear. Then the coal pressing head 4 enters the downward channel, and the fixed rack 10 controls the semi-circular gear 9 to rotate in the reverse direction until the fixed rack 10 is completely disengaged from the semi-circular gear 9. The coal pressing head 4 extrudes the floating coal, and the eccentric counterweight block 8 swings reciprocally to realize the extrusion of the floating coal by the coal pressing head 4.

[0014] Among them, the guiding component 2 includes a through hole provided on the main coal pressing beam 1, a guiding column 11 installed in the through hole, and right-angle fixing seats 12 installed at the upper and lower four corners of the through hole. Wear-resistant blocks 13 are installed on the right-angle fixing seats 12, and the wear-resistant blocks 13 are in contact with the guiding column 11. The contact between the guiding column 11 and the wear-resistant blocks 13 can reduce the wear of the guiding column. At the same time, by replacing the wear-resistant blocks, it can ensure that the up-and-down movement of the guiding column is smoother.

[0015] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of the present invention.
