Description

Technical Field

[0001] The invention belongs to the technical field of coke oven vehicles, and in particular relates to a ramming coal-charging coke-blocking vehicle suitable for coke-side coal loading. Background Art

[0002] The tamping coke oven is a coking process that uses mechanical tamping to compact bulk coal into high-density briquettes before loading them into the carbonization chamber. A tack-charging coke truck pushes the compacted briquettes into the carbonization chamber. Once the coke matures, a pusher on the coke oven's machine side pushes the coke out of the carbonization chamber. Simultaneously, a coke interceptor on the coke side intercepts the coke, allowing it to fall into the coke drum. The carbonization chamber taper, defined as the difference in width between the coke side and the machine side, is designed to reduce resistance to pushing the coke, allowing the mature coke to be smoothly ejected from the carbonization chamber.

[0003] In current coke oven designs, the width of the coke-side carbonization chamber is larger than that of the engine-side carbonization chamber. Conventional coke oven coal loading vehicles operate on the engine side. To ensure smooth loading of rammed coal briquettes into the carbonization chamber, the briquettes must be narrower than the engine-side furnace opening. This restricts the amount of coal that can be loaded into the coke oven. Furthermore, once the briquettes enter the carbonization chamber, the distance between the engine-side briquettes and the furnace wall is inconsistent, resulting in uneven heating of the briquettes.

[0004] Therefore, the machine-side coal loading car has an adverse effect on the uniformity of coal cakes and the life of the furnace body. In order to adapt to the coke-side coal loading technology, it is necessary to develop a coal loading vehicle that works on the coke side of the coke oven. The coordinated operation of the vehicle system is crucial to the efficiency and stability of the coke oven. It is very necessary to develop a highly integrated coke-side operating vehicle. Summary of the Invention

[0005] The purpose of the present invention is to provide a tamping coal-loading and coke-blocking vehicle, which overcomes the shortcomings of the existing technology, highly integrates the three functions of tamping, coal loading and coke blocking into one, has a reasonable layout, and adopts coke-side coal loading technology to adapt to the characteristics of the taper of the coke oven body. At the same time, it has the functions of guiding coke, opening and closing furnace doors, cleaning the furnace frame and removing dust, reducing the footprint and being conducive to the synergistic effect of the vehicle system.

[0006] To achieve the above object, the present invention is implemented through the following technical solutions:

[0007] A tamping coal-loading and coke-blocking car comprises a steel structure car body, a running device, a coal material conveying device, a tamping device, a coal loading device, a coke guiding device, a furnace door opening and closing device, a furnace frame cleaning device and a dust removal device, which is used to match tamping coke ovens, top-loading tamping integrated coke ovens and top-loading modified tamping coke ovens. The steel structure car body is arranged on the coke side of the coke oven. During the coke oven production process, tamping, coal loading and coke blocking operations are completed on the coke side. Facing the coke oven carbonization chamber, from left to right are the furnace frame cleaning device, coke guiding device, furnace door opening and closing device and coal loading device. The tamping device is located directly above the coal box of the coal loading device, and the coal material conveying device is located on one side of the tamping device. The tamping coal cake operation is performed while the coal material conveying device adds coal to the coal box. The dust removal device is located above the coke guiding device and the coal loading device, and the running device is located at the bottom of the steel structure car body. The arrangement of the coal loading device and the coke guiding device is adapted to the coke pushing sequence of the coke oven.

The coal box includes a front baffle, a rear baffle, a left baffle and a right baffle, forming a trapezoidal coal box that is narrow in front and wide in the back. The front and rear tapers of the coal box are adapted to the taper of the coke oven carbonization chamber. The coal supporting base plate is moved forward and retracted through a moving plate mechanism. The moving plate mechanism includes a sprocket and a chain plate. The sprocket is connected to the moving plate reduction motor through a sprocket shaft.

[0009] Furthermore, the tamping device includes a steel structure frame, a lifting drive mechanism and a tamping hammer, the lifting drive mechanism is respectively connected to the steel structure frame and the tamping hammer, and the lifting drive mechanism is a cylinder or a lifting reducer.

[0010] Furthermore, the running device includes a bogie and wheels, the bogie is connected to the bottom of the steel structure car body, and the wheels are connected to the bottom of the bogie.

[0011] Furthermore, the dust removal device includes an induced draft fan and a dust collecting hood for collecting flue gas generated during the coal loading and coke intercepting process. The dust collecting hood is long and strip-shaped and is sealed above the coal loading device and the coke guiding device.

[0012] Furthermore, for a ramming coke oven with a coke pushing sequence of 5-2, the distance between the center of the coal charging device and the center of the coke guiding device is 5 times the center distance of the carbonization chamber.

[0013] Furthermore, the furnace frame cleaning device includes compressed air nozzles or steel brushes arranged in rows up and down; the coal conveying device includes a coal conveying trestle, a coal conveying car and a shaking feeder.

[0014] Furthermore, during the coke oven production process, the working process is as follows: 1) the ramming coal-loading coke-blocking car starts to move toward the target position. During the movement, the coal sent by the coal preparation is sent to the ramming coal-loading coke-blocking car through the coal conveying device, and the coal conveyor loads the coal into the coal box. The coal conveyor loads the coal into the coal box. During the discharge process, the ramming device works to tamp the coal put into the coal box to form coal cakes; 2) After the coal is received, the ramming coal-loading coke-blocking car moves to the designated position, the center line of the coal loading device is opposite to the center line of the n-th hole carbonization chamber, and the center line of the coke guide device is opposite to the center line of the n+5-th hole carbonization chamber; 3) the coal loading is opened. The front baffle and right baffle of the device, and the coal supporting bottom plate hold the coal and are driven by the shifting plate mechanism to deliver coal to the n-hole carbonization chamber. At the same time, the n+5-hole carbonization chamber performs the coke pushing operation, and the coke guiding device guides the coke so that the coke falls smoothly into the coke pot; 4) After the coal is delivered to the n-hole carbonization chamber, the coal supporting bottom plate is driven by the shifting plate mechanism to be retracted, and the front baffle and right baffle of the coal loading device are closed at the same time; the flue gas during the coal loading and coke intercepting process is collected and processed by the dust removal device, and the cleaning operation of the furnace door frame is completed by the furnace frame cleaning device; after the coal loading and coke pushing operations are completed, the tamping coal loading and coke intercepting car continues to move to the next target position, ready to enter the next working cycle.

[0015] Furthermore, a driver's cab is provided on the steel structure vehicle body, and the driver and crew members carry out the coal receiving, tamping, coal loading and coke guiding operations in each carbonization chamber according to the coke discharge sequence.

[0016] Furthermore, the working process can be completed by remote control or under intelligent unmanned control.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) The three functions of tamping, coal loading and coke interception are highly integrated into one, with a small footprint, reasonable layout, low investment, and multiple uses of one vehicle. This is conducive to the synergy of the vehicle system. The coke oven machinery is highly integrated, which optimizes space utilization and saves single-hole operation time.

[0019] 2) The vehicle-side coal loading technology adapts to the taper characteristics of the coke oven body. The taper of the trapezoidal structure of the coal box on the vehicle is adapted to the carbonization chamber of the coke oven. Compared with the traditional machine-side coal loading vehicle, the coal loading capacity is larger, the coal cake is more stable, and the stability of the furnace body is better;

[0020] 3) No need for a fixed coal tower, saving space. At the same time, the tamping of coal cakes is carried out on the vehicle, and there is no need to go back and forth to the coal tower to receive coal and tamping operations, saving time and effectively improving efficiency.

[0021] 4) The invention has a wide range of applications and is suitable for upgrading and renovating ramming coke ovens, top-loading ramming integrated coke ovens, and top-loading to ramming coke ovens. Compared with traditional top-loading coke ovens, the invention has the advantage of being able to use a high proportion of weakly caking coal, thereby reducing coal blending costs.
