The utility model is put into the cutter shell after the spring is sleeved on the rotary cutter bar, and the tail part of the rotary cutter bar is provided with a balancing weight; the head of the rotary cutter rod is an arc-shaped scraper, and the tail of the rotary cutter rod is provided with a fan-shaped groove; a fan-shaped key is arranged on the cutter shell corresponding to the fan-shaped groove at the tail part of the scraper; the angle of the fan-shaped groove at the tail part of the rotary cutter rod is larger than that of the fan-shaped key at the tail part of the cutter shell, and the rotary cutter rod and the fan-shaped groove can perform rotary displacement at a certain angle. The utility model has the advantages that: 1. the rotary scraper realizes rotary cleaning and resetting by utilizing gravity and friction force, does not need the cooperation of various scrapers, simplifies the equipment structure and reduces the maintenance rate. 2. The scraper adopts elastic flexible compensation, so that the adaptability of the device is enhanced, and the damage to the edge of the furnace door is reduced.
Description
Technical Field
The utility model belongs to the technical field of metallurgical industry, and relates to a coke oven furnace door cleaning device of a coke-oven plant.
Background
The knife edge of the coke oven door and the oven brick have a reverse inclined surface, the reverse inclined surface mainly has the function of conducting the raw coke oven gas generated in the coking process, but tar and cinder generated in the coking process can be adhered to the reverse inclined surface to block a channel of the reverse inclined surface, so that the conduction of the raw coke oven gas is influenced.
At present, no scraper has the function of cleaning both the edge of the scraper and the reverse slope. The current scrapers are all single-function, need several scrapers to have the cooperation to use, and its mode has many drawbacks, and its shortcoming is as follows:
1. the scraper has a single function, and needs to be matched with a plurality of scrapers, so that fault points can be increased, and the maintenance rate is increased;
2. the scraper structure is too rigid, and once the scraper structure fails, equipment damage or furnace door damage can be caused.
Disclosure of Invention
The utility model aims to provide a rotary scraper of a coke oven door cleaning device aiming at the problems so as to further improve the working efficiency.
The technical scheme of the utility model is that: a rotary scraper of a coke oven door cleaning device is sleeved with a spring by a rotary cutter bar and then is arranged in a cutter shell, and the tail part of the rotary cutter bar is provided with a balancing weight and is locked by a screw cap; the head of the rotary cutter rod is an arc-shaped scraper, and the tail of the rotary cutter rod is provided with a fan-shaped groove; a fan-shaped key is arranged on the cutter shell corresponding to the fan-shaped groove at the tail part of the scraper; the angle of the fan-shaped groove at the tail part of the rotary cutter rod is larger than that of the fan-shaped key at the tail part of the cutter shell, and the rotary cutter rod and the fan-shaped groove can perform rotary displacement at a certain angle.
The utility model has the advantages that: 1. the rotary scraper realizes rotary cleaning and resetting by utilizing gravity and friction force, does not need the cooperation of various scrapers, simplifies the equipment structure and reduces the maintenance rate. 2. The scraper adopts elastic flexible compensation, so that the adaptability of the device is enhanced, and the damage to the edge of the furnace door is reduced.

The reference numbers: the rotary knife comprises a rotary knife bar 1, a sector groove 1-1, a knife shell 2, a sector key 2-1, a spring 3, a balancing weight 4, a screw cap 5, a knife edge 6, a reverse inclined plane 7 and a furnace brick 8.
Detailed Description
The structure of the utility model is as shown in the attached figures 1 and 2, and the structure characteristics are further explained by combining the working process with the attached figures 3, 4, 5 and 6:
the rotary scraper is arranged in a cutter shell 2 after a spring 3 is sleeved on a rotary cutter bar 1, and a balancing weight 4 is arranged at the tail part of the rotary cutter bar 1 and then locked by a screw cap 5. As shown in figure 1.
The angle range of the fan-shaped groove 1-1 at the tail part of the rotating cutter rod is 70-80 degrees, the angle range of the fan-shaped key 2-1 at the tail part of the cutter shell is 35-45 degrees, and the two can rotate by 35 degrees.
The working principle is as follows: in the initial position, the rotating scraper enables the narrow head of the rotating cutter bar 1 to face upwards under the action of the gravity of the balancing weight 4, and the rotating cutter bar 1 of the rotating scraper can smoothly contact with the cutter edge 6 behind the furnace brick 8 when moving forwards, as shown in attached figures 3 and 4.
The during operation rotary scraper moves forward, and rotary cutter arbor 1 backward movement compression spring 3 when rotary cutter arbor 1 contact sword limit 6 of rotary scraper guarantees that rotary cutter arbor 1 and sword limit 6 have certain pressure, also can play the effect of elastic compensation, and protection sword limit 6 is not hindered by the collision.
When the rotary scraper moves upwards, the friction force generated by the relative motion of the rotary cutter bar 1 and the cutter edge 6 and the resistance of the tar and cinder foreign matters enable the rotary cutter bar 1 to rotate for a certain angle by overcoming the gravity of the balancing weight 4, so that the wider side of the head of the rotary cutter bar 1 faces upwards, and the tar, cinder and the like in the reverse inclined plane 7 are cleaned, as shown in the attached drawings 5 and 6.
Finally, after the clearance finishes, rotatory scraper backward motion, rotatory cutter arbor 1 and the separation of sword limit 6 are in the twinkling of an eye, and rotatory cutter arbor 1 resets under the action of gravity of balancing weight 4, and the narrower one side of rotatory cutter arbor 1 head is up, and rotatory cutter arbor 1 pops out forward under the effect of spring 3 simultaneously and resets, guarantees that rotatory scraper withdraws from smoothly, accomplishes and cleans, as shown in attached 3, attached 4.
