1). single or double acting door pin device (3) is by spring case (8), end cap (9), interior coiled spring (10), cycle spring (11), cardan shaft (12), pressure plate (13), latch screw (14), keeper (15), guide cylinder (16), set nut (17) is formed, interior coiled spring (10) and cycle spring (11) are arranged in the bottom of spring case (8) pressure plate (13), all be connected and fixed between spring case (8) and oven door body (1) and the end cap (9) with bolt, the thin circular shaft in thick two in the middle of cardan shaft (12) is processed into, and the lower surface and the pressure plate (13) of thick axle welds together in the middle of making, below thin axle outside be with guide cylinder (16), guide cylinder (16) and oven door body (1) are threaded fixing, latch screw (14) and keeper (15) are threaded for the T type, with set nut (17) the related keeper of latch screw (14) (15) are locked in the upper end of cardan shaft (12);
2). elasticity knife-edge device (4) adopts L type elasticity knife-edge device, it is by L type knife-edge (18), pressing plate (19), roof pressure plug (23), spring support (21), spring (22), sleeve (23), pressing plate (24), regulate bolt (25), adjusting bolt (26) is formed, L type knife-edge (18) is by pressing plate (19), spring support (21) is connected and fixed with bolt with oven door body (1), spring (22) is arranged in below the pressing plate (24) of sleeve (23), spring (22) and sleeve (23) are pressed on the L type knife-edge (18) by the roof pressure plug (20) that passes hole under the spring support (21), adjusting bolt (25) roof pressure that passes the last hole of spring support (21) is regulated bolt (26) and is passed the flank hole roof pressure of oven door body (1) on spring support (21) on pressing plate (24).
The advantage of the utility model L type elasticity knife-edge spring keeper suspension type coke oven door is: simple in structure, cost is low; Stressed even, not yielding and impaired, the life-span is long; Good sealing effect has alleviated environmental pollution; Knife-edge changes and keeper conveniently opening and closing, quick, is convenient to realize automated operation, greatly reduces labour intensity.
Introduce the detailed content of the utility model L type elasticity knife-edge spring keeper suspension type coke oven door below in conjunction with drawings and Examples.
Fig. 1 is the one-piece construction figure of L type elasticity knife-edge spring keeper suspension type coke oven door.
Fig. 2 is the structure iron (the A-A sectional drawing among Fig. 1) of single or double acting door pin device (3).
Fig. 3 is the structure iron (the B-B sectional drawing among Fig. 1) of L type elasticity knife-edge device (4).
As Fig. 1, Fig. 2, embodiment shown in Figure 3, among Fig. 1, oven door body of the utility model coke oven door (1) and furnace door brick groove (2) are ironcasting, and the furnace door brick groove is lined with refractory brick in (2), play heat-blocking action, furnace door brick groove (2) is connected with bolt with oven door body (1).Open type in little fire door (5) employing, no rocking bar problem on deformation, it is few to smolder, free from environmental pollution so the life-span is long, it is positioned at the top of oven door body (1).Single or double acting door pin device (3) is respectively established one up and down in oven door body (1), symmetric arrangement, and the upper springs bolt apparatus is positioned at the bottom of little fire door (5).Suspended idler (6) is respectively established one in the fire door both sides, be fastened on the oven door body (1) by roller carrier shaft (7), it is positioned at the middle and upper part of oven door body (1), when closing fire door, two carrying rollers are hung on the roller seat of firedoor frame, the contraposition of this suspension type fire door is accurate, and the position is difficult for change, can significantly reduce the cleaning works amount of fire door knife-edge and firedoor frame minute surface again.Bottom surface because of fire door bottom brick groove (2) contacts with the coking chamber bottom simultaneously, and a small amount of breeze cleaning in bottom does not influence the absolute altitude of fire door keeper only.The elasticity knife-edge device (4) of fire door adopts L type elasticity knife-edge device, its be evenly arranged in fire door around, the spacing of knife-edge spring roof pressure point is generally 200-240mm and is advisable, but about fire door four jiaos of places that easily smolder, can increase the roof pressure point, reduce the distance.
Among Fig. 2, interior coiled spring (10) and cycle spring (11) are arranged in the bottom of spring case (8) pressure plate (13), all are connected and fixed with bolt between spring case (8) and oven door body (1) and the end cap (9).The thin circular shaft in thick two in the middle of cardan shaft (12) is processed into, and lower surface and the pressure plate (13) of thick axle welds together in the middle of making, below thin outside be with guide cylinder (16), guide cylinder (16) is threaded fixing with oven door body (1).Latch screw (14) and keeper (15) are threaded for the T type, because of keeper (15) is heavier, adopt T type screw thread, and contact surface is big, connects reliably, with set nut (17) the related keeper of latch screw (14) (15) is locked in the upper end of cardan shaft (12).During installation, latch screw (14) be can regulate and cardan shaft (12) and pressure plate (13) depressed, make the gap of leaving 8-15mm between pressure plate (13) and the end cap (9), the elastic force that this gap produces can guarantee the sealing of fire door L type knife-edge (18) and keeper (15) and fix.When opening and closing fire door, by the travel direction of guide cylinder (16) control cardan shaft (12), in order to avoid cause inclination to cause the unfavorable factors such as inclination of keeper (15) because of cardan shaft (12).
Among Fig. 3, L type knife-edge (18) be welded by the cutter envelope body that L type web that is pressed into through cold punching with stainless-steel sheet and stainless-steel sheet are made or be rolled into whole knife-edge with stainless-steel sheet, L type web preferably adopts the thick stainless-steel sheet cold stamping of 2mm to form, cutter envelope body preferably adopts the stainless-steel sheet manufacturing of thick 6mm, long 34mm, wide 6mm, and the cutter front cover is wide to be good with 3.5mm.The web vertical edge of L type knife-edge (18) is close to the side all around that leans against oven door body (1), be connected and fixed with bolt with oven door body (1) by pressing plate (19), spring support (21), spring (22) is arranged in below the pressing plate (24) of sleeve (23), and spring (22) and sleeve (23) are pressed on the L type knife-edge (18) by the roof pressure plug (20) that passes hole under the spring support (21).Adjusting bolt (25) roof pressure that passes the last hole of spring support (21) is regulated bolt (26) and is passed the flank hole roof pressure of oven door body (1) on spring support (21) on pressing plate (24).The regulation range of L type knife-edge (18) is very big, can adjust pressure to knife-edge by regulating bolt (26), can also adjust the draught of spring (22) by adjusting bolt (25) simultaneously, thereby make knife-edge reach seal request well.
