Technical Field
The invention relates to the field of coke ovens for producing coal gas, coke, tar or the like by dry distillation, in particular to an automatic tar cleaning device in front of a coke oven.
Background
In the production process of the coke oven, after the coke guide and the coke quenching car are ready for coke receiving, the coke pusher starts coke pushing operation. When the oven door is removed by pushing coke each time, the tar and the oven head coke which fall from the oven door, the oven frame and the upper part of the oven head coke, and the tail coke brought out by the coke pushing sliding plate when retreating all fall onto the coke flowing plate. At this time, the furnace door worker needs to perform manual cleaning work by using a tool in front of the furnace.
The production environment of the coke oven is severe, the temperature in front of the coke oven reaches 1000 ℃, and the process requires that the time from opening to closing the oven door is very short, so that an oven door worker needs to clean graphite on the oven wall at the high temperature within a very short time, ensure that the cross iron of the oven door is in place, and also needs to shovel off tar on a coke plate, thereby not only having high labor intensity and great harm to the personal safety, but also having an unsatisfactory cleaning effect.

The invention aims to: aiming at the problems, the automatic cleaning device for the coke oven front tar is provided to improve the safety of the coke oven front tar cleaning work.
The technical scheme of the invention is as follows: an automatic cleaning device of stokehole tar, its characterized in that the device includes:
the guide rod is transversely arranged and can be axially movably connected on a door opening mechanism frame of the coke pusher or the coke guide in a penetrating way;
the stretching chain is connected between the door opening mechanism frame and the guide rod;
one end of the compression spring is abutted and connected to the door opening mechanism frame, and the other end of the compression spring is abutted and connected to the joint of the stretching chain and the guide rod;
the coke cleaning plate is hinged to one end of the guide rod;
one end of the extension spring is fixedly connected to the guide rod, and the other end of the extension spring is fixedly connected to the coke cleaning plate.
On the basis of the technical scheme, the invention also comprises the following preferable scheme:
the stretching chain and the guide rod are arranged in the same vertical plane, and an included angle between the stretching chain and the guide rod is smaller than 90 degrees.
The upper end of the stretching chain is connected to the door opening mechanism frame, and the lower end of the stretching chain is connected to the guide rod.
The vertical plane where the stretching chain and the guide rod are located is perpendicular to the coke cleaning plate.
The coke cleaning plate is hinged to the end part of the guide rod through a connecting plate.
One end of the extension spring is fixedly connected to the guide rod through a fixing support.
The invention has the advantages that: the automatic cleaning device for the coke tar in the front of the coke oven basically realizes unmanned operation of cleaning the coke dripping plate, greatly reduces the working strength of the coke oven discharging work, greatly improves the operation environment in the front of the coke oven and improves the production safety coefficient; the coke oven can effectively collect the tar and the furnace end coke which are difficult to collect and pollute the environment, changes waste into valuable, improves the economic benefit and the social benefit, and is beneficial to the clean, efficient and stable operation of the coke oven production.
Drawings
The invention will be further described with reference to the following drawings and specific embodiments:
FIG. 1 is a schematic structural diagram of an automatic cleaning device for stokehole tar according to an embodiment of the present invention;
wherein: 1 compression spring, 2 guide connecting rods, 3 coke cleaning plates, 4 connecting plates, 5 extension springs, 6 fixing supports and 7 extension chains.
Detailed Description
Fig. 1 shows a specific embodiment of the automatic cleaning device for coke oven front tar, which is installed below a door opening mechanism of a coke pusher or a coke guide, and in practical application, the device is arranged below the door opening mechanism of the coke pusher and the coke guide, and mainly comprises a guide rod 2, an extension chain 7, a compression spring 1, a coke cleaning plate 3, an extension spring 5 and the like. Wherein:
the guide rod 2 is transversely arranged and can be axially movably connected on a door opening mechanism frame 8 of the coke pusher or the coke guide in a penetrating way. The tension chain 7 is connected between the door opening mechanism frame 8 and the guide bar 2. The compression spring 1 is sleeved outside the guide rod 2, one end of the compression spring 1 is connected to the door opening mechanism frame 8 in an abutting mode, and the other end of the compression spring 1 is connected to the connecting position of the tension chain 7 and the guide rod 2 in an abutting mode. In this embodiment, the stretching chain 7 and the guide bar 2 are arranged in the same vertical plane, an included angle between the stretching chain 7 and the guide bar 2 is an acute angle (smaller than 90 °), the upper end of the stretching chain 7 is connected to the door opening mechanism frame 8, and the lower end of the stretching chain 7 is connected to the guide bar 2. The tension chain 7 is arranged such that it is possible on the one hand to exert a certain compression force on the compression spring 1 and on the other hand to prevent the guide bar 2 from moving to the right in fig. 1 out of connection with the door opening mechanism frame 8. The coke cleaning plate 3 is hinged to one end of the guide rod 2 through a connecting plate 4 and is responsible for cleaning tar on the surface of the coke dripping plate. One end of the extension spring 5 is fixedly connected to the guide rod 2 through a fixing bracket 6, and the other end is fixedly connected to the coke cleaning plate 3. And the decoking plate 3 is perpendicular to the vertical plane in which the drawing chain 7 and the guide bar 2 lie. I.e. the vertical plane in which the drawing chain 7 and the guide bar 2 are located, is arranged perpendicular to the decoking plate 3.
When the coke is mature, the coke pusher and the coke guide are aligned simultaneously to open the oven door, and the automatic tar cleaning device aligns the coke cleaning plate 3 to the surface of the coke dripping plate by the action of opening the oven door and is tightly attached to the coke dripping plate. When the furnace door is opened, the coke cleaning plate 3 approaches to the coke dripping plate, and under the combined action of the compression spring 1 and the extension spring 5, the angle of the coke cleaning plate 3 is automatically adjusted to ensure that the coke cleaning plate 3 is always in close contact with the coke dripping plate, so that residual tar on the coke dripping plate can be scraped completely, and meanwhile, tar flowing out of the furnace mouth can be collected completely. Practice proves that the coke cleaning effect can reach more than 90%.
The up-and-down telescopic action of the extension spring 5 controls the inclination angle of the coke cleaning plate 3, thereby realizing the close adhesion of the coke cleaning plate 3 and the coke dripping plate. The horizontal telescopic motion of the compression spring 1 ensures that when the coke cleaning plate 3 is contacted with the coke dripping plate, the horizontal position of the coke cleaning plate 3 relative to the door opening mechanism frame 8 can be automatically adjusted according to the change of the contact part, so that the coke cleaning plate 3 is prevented from being jammed with the coke dripping plate (the coke dripping plate is obliquely arranged) in the moving process, and the coke cleaning plate 3 is also ensured to be tightly attached to the coke dripping plate.
It should be understood that the above-mentioned embodiments are only illustrative of the technical concepts and features of the present invention, and the purpose of the present invention is to enable people to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical scheme of the invention are covered in the protection scope of the invention.
