Abstract
The utility model relates to a scraper for cleaning graphite from the carbide chamber of a coke oven. The utility model is installed on the back face of pushing ram head and move forward with the pushing ram to scrape off graphite on the top and two wall surface of the carbide chamber; a spring connection is adopted between two scraper blades of the scraper; a rotation shaft with a sleeve is adopted to connect the scrapers and a bottom plate. The utility model has the advantages that the use is flexible and convenient, workers' labor intensity in cleaning graphite can be reduced, the quality and output of coke is improved, thereby, the recovery ratio of products is improved, and the service life of a coke oven is prolonged.
Description
The utility model relates to a kind of scraper plate machine that cleans coke furnace carbonization chamber graphite.
At present, the employing that the method for cleaning coke furnace carbonization chamber graphite has is opened the coal port lid in the coking chamber coking later stage, the upcast lid, the method of port door scoria China ink, the employing that has is manually beaten graphite with six-edged steel pricker (or pneumatic pick) after coke pushing method, these cleaning method labor strength are big, and the coking chamber temperature reduces, furnace wall is fragile, directly has influence on the work-ing life of the output and quality and the body of heater of coke.For addressing the above problem, the present utility model people discloses a kind of scraper plate machine (Fig. 1) that cleans coke furnace carbonization chamber graphite in " fuel and chemical industry " the 22nd the 5th phase of volume (total the 174th phase of phase) " cleaning of coking chamber graphite " literary composition that China publishes in September, 1991, the pattern of this scraper plate machine is the allocation formula, be installed in the back up pad position of pushing ram back, with wiping off before the pushing ram and then the graphite of top and two walls apart from bar head 300-400mm.The scraper plate machine is to be done by the thick steel plate of 10mm, and the scraper plate front is 45 ° knife-edge, and the back is welded on the scraper plate machine bottom board, on the base plate, in down three places be provided with lacing wire and be connected with coke pusher shoe, the scraper plate width highly is lower than the horizontal brick of pusher side fire door less than the coking chamber width.Though this scraper plate machine can alleviate working strength of workers and improve converter life, but still deposit when coke pusher shoe and scraper plate machine and coking chamber deflection slightly owing to support with steel plate between two knife-edge scraper plates, then cause the coking chamber wall impaired, the graphite at coking chamber top also is difficult for the defective of scraping.
The purpose of this utility model is to provide a kind of scraper plate machine of improved cleaning coke furnace carbonization chamber graphite, it can overcome effectively when coke pusher shoe and scraper plate machine and coking chamber slightly deflection just cause the impaired and coking chamber top graphite of coking chamber wall to be difficult for the defective of scraping.
The purpose of this utility model can realize by following measure:
The utility model (Fig. 2) is a kind of scraper plate machine that cleans coke furnace carbonization chamber graphite, and it is the knife-edge scraper plate (6) (7) of acute angle by the front, and knife-edge scraper plate web member (8) lacing wire (16) is formed.Knife-edge scraper plate (6) (7) and base plate (12) (95 °-175 °) in obtuse angle are connected, and base plate (12) and pushing ram are fixed on the back up pad position with lacing wire (16).The width of two knife-edge scraper plates highly is lower than the horizontal brick of pusher side fire door less than pusher side coking chamber width (between the 5-12mm); It is characterized in that the web member between knife-edge scraper plate (6) (7) is spring (8), spring (8) is fixed on the knife-edge scraper plate (6) (7) with fixed leg (9) (15), knife-edge scraper plate (6) (7) back is connected with rotating shaft (10) (11) respectively, the axle sleeve (13) (14) of rotating shaft (10) (11) outside is connected with base plate (12) respectively, the upper and lower ends of rotating shaft (10) (11) stretches out axle sleeve respectively and is connected with scraper plate, but height and scraper plate (6) (7) are contour or be lower than scraper plate.
Because the utility model is connected the mode of connection between the knife-edge scraper plate by the fixedly connected spring that changes into, set up two simultaneously and rotated rotating shaft flexibly, so coke pusher shoe and scraper plate machine to coking chamber slightly deflection can not cause the wall that scratches coking chamber yet, not only can wipe the graphite at coking chamber top off but also can make metope not impaired.Overcome effectively prior art coke pusher shoe and scraper plate machine to coking chamber slightly deflection make the impaired and top of coking chamber metope be difficult for the defective of scraping.
The drawing of the utility model accompanying drawing is described as follows:
Fig. 1 is the scraper plate machine of prior art cleaning coke furnace carbonization chamber graphite, among the figure 1, the 2-front is 45 ° knife-edge scraper plate, 3-knife-edge scraper plate web member (supporting steel plate), 4-scraper plate machine bottom board, 5-lacing wire.
Fig. 2 is the scraper plate machine of the utility model cleaning coke furnace carbonization chamber graphite.Among the figure; 6, the 7-front is the knife-edge scraper plate of acute angle (10 °-60 °), and 8-knife-edge scraper plate connects the spring (8) of strut member, and 9,15-knife-edge scraper plate connects the reference column of the spring (8) of strut member.10,11-rotating shaft, 12-is the scraper plate machine bottom board, 13, the overcoat of 14-rotating shaft, the 16-lacing wire
The utility model is described in further detail below in conjunction with drawings and Examples:
The utility model scraper plate machine is manufactured by the thick steel plate of 20mm, the front of knife-edge scraper plate (6) (7) be acute angle (between 10 °-60 °) back up and down respectively and rotating shaft (10) (11) weld together, the reinforcing bar of φ 12 * 160mm is adopted in rotating shaft, several centimetres up and down in overcoat is stretched out in rotating shaft, so that scraper plate and rotating shaft firmly weld together.The steel pipe of rotating shaft overcoat (13) (14) employing φ 25 * 120 and base plate (12) be (between 95 °-175 °) in obtuse angle.Use internal diameter φ 10mm external diameter φ 85mm between knife-edge scraper plate (6) (7), the 60Si of long 194mm
2MnA spring (load≤0.3kg/cm
2).The reinforcing bar that is welded with the long φ 12mm of 70mm on the knife-edge scraper plate is the spring reference column (9) (15) of steel spring position fixedly, the base plate upper, middle and lower are welded with the long lacing wire (16) of three couples of 400mm that welds together with coke pusher shoe, the width of knife-edge scraper plate (6) (7) is less than pusher side coking chamber width (between the 4-12mm), and is highly contour or be lower than the horizontal brick of pusher side fire door.
The utility model is used for " 70 " type coking furnace, and result of use is good. Through using proof the utility model compared with prior art to have the following advantages:
1, coke pusher shoe and scrapper conveyor to carbonization chamber slightly deflection can not scratch the carbonization chamber metope, the easy scraping of carbonization chamber top graphite yet.
2, flexible and convenient to use.
3, body of heater high life.
4, alleviate labor strength.
5, help improving coke output quality and change production yield rate.
6, not only economy but also less manpower.
