Abstract

This utility model relates to the field of coke oven coal compaction technology, specifically an adjustable tamping force coke oven coal cake compaction device, including a machine body and a pressing mechanism. A material discharge trough is provided on the surface of the machine body, and the pressing mechanism is mounted on the surface of the machine body. This utility model uses a lifting cylinder to move a movable frame, allowing for initial pressing of the pressure ring. Then, through a drive assembly, the positions of different cams (cam one, cam two, cam three) can be flexibly switched.

This reduces problems of insufficient compaction or excessive compression caused by differences in coal materials, improving overall practicality.

Description

Technical Field

[0001] This utility model relates to the field of coke oven coal compaction technology, and in particular to a coke oven coal cake compaction device with adjustable tamping force. Background Technology

[0002] Coke oven briquettes are the raw material form for coking in coke ovens. They are made by compacting blended coal using a compaction device. The production process involves loading crushed coals (such as coking coal and fat coal in proportion) into a compaction device and compacting them using an adjustable mechanical structure to ensure uniform coal density and strength, thus preventing breakage when loaded into the coke oven.

[0003] Qualified coal cakes can be heated evenly in the high-temperature dry distillation of coke ovens, ensuring stable coke quality. They are a key intermediate product connecting coal preparation and coke production, and have a significant impact on coking efficiency and coke quality.

[0004] In daily operation, it has been found that existing coke oven briquette compaction devices typically have a fixed tamping force setting, which cannot be flexibly adjusted according to specific scenarios. When processing coal with different proportions (e.g., coal with a high proportion of lean coal requires greater force, while coal with a high proportion of coking coal requires less force), the fixed force is difficult to adapt. This single-force design results in poor applicability of the device in diverse production scenarios. Insufficient force may cause the briquette to be loose and easily broken, while excessive force may cause over-compression of the coal, affecting the dry distillation effect and causing inconvenience in use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the tamping force of existing technologies is usually fixed and cannot be flexibly adjusted according to specific scenarios, and to propose a coke oven coal cake compaction device with adjustable tamping force.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a coke oven briquette compaction device with adjustable tamping force, comprising a body and a pressing mechanism, wherein a material discharge trough is provided on the surface of the body, and the pressing mechanism is disposed on the surface of the body.

[0007] The pressing mechanism includes a movable frame slidably connected to the inner wall of the machine body. Two lifting cylinders are installed on the inner wall of the movable frame, and the output ends of the lifting cylinders are fixedly connected to the surface of the movable frame. A top rod is slidably connected to the inner wall of the movable frame, and a pressure ring is fixedly connected to the lower end of the top rod. A spring is sleeved on the surface of the top rod, and both ends of the spring are fixedly connected to the top rod and the surface of the movable frame, respectively. A fixed shaft is fixedly connected to the inner wall of the top rod, and the fixed shaft is inserted into the inner wall of the sliding hole. A fixed frame is fixedly connected to the upper surface of the movable frame, and a pressure rod is rotatably connected to the fixed frame. A sliding hole is opened on the surface of the pressure rod. A rotating shaft is rotatably connected to the inner wall of the movable frame, and a sliding sleeve is slidably connected to the rotating shaft. Cam 1, Cam 2, and Cam 3 are sequentially fixedly connected to the surface of the sliding sleeve. An adjustment component is provided on the movable frame to control the movement of the sliding sleeve and to press the pressure rod using different cams. A rotating component is also provided on the movable frame to control the rotation of the rotating shaft.

[0008] Preferably, the adjustment assembly includes a control rod slidably connected to the inner wall of the movable frame, and the control rod rotatably connected to the surface of the sliding sleeve; a threaded rod is rotatably connected to the inner wall of the movable frame, and the threaded rod is threadedly connected to the inner wall of the control rod; a drive motor is installed on the inner wall of the movable frame, and the output end of the drive motor is fixedly connected to one end of the threaded rod. By setting the adjustment assembly, turning on the drive motor causes the threaded rod to rotate, the threaded rod controls the movement of the control rod, and the control rod drives the sliding sleeve to move, thereby adjusting the positions of cam one, cam two, and cam three.

[0009] Preferably, a positioning ring is fixedly connected to the surface of the top rod. The positioning ring fits against the lower surface of the movable frame to achieve positioning.

[0010] Preferably, the rotating assembly includes a push cylinder mounted on the upper surface of the movable frame, with a rack fixedly connected to the output end of the push cylinder; two gears are fixedly connected to the surface of the rotating shaft, and the gears mesh with the rack. By setting the rotating assembly, the push cylinder drives the rack to move, and the rack, in conjunction with the gears, can drive the rotating shaft and the sliding sleeve to rotate. The sliding sleeve controls cam one, cam two, or cam three to press the pressure rod, thereby realizing downward adjustment.

[0011] Preferably, two guide rods are fixedly connected to the surface of the movable frame, and the guide rods are slidably connected to the inner wall of the rack. The two guide rods can improve the stability of the rack's movement.

[0012] Preferably, the rack is U-shaped and consists of two racks and a connecting rod for connecting the two racks.

[0013] Preferably, the inner wall of the machine body is provided with a pushing assembly, which includes a pushing cylinder installed in the inner wall of the machine body. The output end of the pushing cylinder extends into the discharge trough and is fixedly connected to a top ring. By setting the pushing assembly, the pushing cylinder can drive the top ring to move, thereby pushing out the pressed coke oven coal cake in the discharge trough.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, a lifting cylinder drives the moving frame to move, allowing the pressure ring to undergo initial compression. Then, through a drive assembly, the positions of different cams (cam one, cam two, cam three) can be flexibly switched. In conjunction with a flipping assembly, the rotating shaft and corresponding cams rotate and squeeze the pressure rod, thereby changing the compression amplitude of the pressure ring. This allows for rapid adjustment of the compaction force to meet different coal characteristics (such as particle size, moisture content, and proportion) or coke oven process requirements, ensuring that the coal cake density meets production standards. This reduces the problem of insufficient compaction or excessive compression caused by differences in coal materials, and improves the overall practicality.

[0016] In this invention, the pusher cylinder automatically pushes out the finished coal cake through the top ring, which facilitates subsequent handling and improves overall usability. Attached Figure Description

A sliding sleeve 311 is slidably connected to the rotating shaft 310. A cam 1 312, a cam 2 313, and a cam 314 are fixedly connected to the surface of the sliding sleeve 311 in sequence. An adjustment component 36 is provided on the movable frame 31 to control the movement of the sliding sleeve 311. Different cams are used to press the pressure rod 39. A rotating component 35 is also provided on the movable frame 31 to control the rotation of the rotating shaft 310.

[0027] Specifically, the adjustment assembly 36 includes a control rod 361 that is slidably connected to the inner wall of the movable frame 31, and the control rod 361 is rotatably connected to the surface of the sliding sleeve 311; a threaded rod 362 is rotatably connected to the inner wall of the movable frame 31, and the threaded rod 362 is threadedly connected to the inner wall of the control rod 361; a drive motor 363 is installed on the inner wall of the movable frame 31, and the output end of the drive motor 363 is fixedly connected to one end of the threaded rod 362.

[0028] The above-mentioned method involves turning on the drive motor 363, which drives the threaded rod 362 to rotate. The threaded rod 362 controls the control rod 361 to move, and the control rod 361 drives the sliding sleeve 311 to move, thereby adjusting the positions of cam 1 312, cam 2 313 and cam 314.

[0029] Specifically, a positioning ring 317 is fixedly connected to the surface of the top rod 32. The positioning ring 317 is in contact with the lower surface of the movable frame 31 to achieve positioning operation.

[0030] Specifically, the rotating assembly 35 includes a push cylinder 354 mounted on the upper surface of the movable frame 31, with a rack 352 fixedly connected to the output end of the push cylinder 354; two gears 351 are fixedly connected to the surface of the rotating shaft 310, and the gears 351 mesh with the rack 352.
