Description
Technical Field
The utility model relates to a simple gun nozzle structure of a mud gun of an Ou-Meta furnace, which can be quickly disassembled.
Background
The mud gun of the European and metallurgical furnace belongs to important equipment in front of a metallurgical blast furnace and has the functions of sealing an iron notch after the iron notch of the European and metallurgical furnace is completely tapped and preventing the iron notch from splashing, so that the working environment of the mud gun of the European and metallurgical furnace is severe, particularly the gun nozzle of the mud gun is in contact with slag iron when the slag iron at the iron notch of the European and metallurgical furnace is completely tapped and blocked, and the mud gun is extremely easy to burn and lose. The gun nozzle and the gun body of the common clay gun are connected by bolts, and the gun nozzle is severe in working condition, severe in corrosion of the bolts and difficult to disassemble. If the accident that the iron notch can not be blocked occurs, the gun nozzle is burnt, and the blast furnace production is seriously restricted because the replacement time is long and the gun nozzle needs to be replaced when the blast furnace is stopped.
SUMMERY OF THE UTILITY MODEL
The problem of long replacing time of the gun nozzle of the mud gun is solved. The utility model provides a simple muzzle structure of a mud gun of an Ou-Meta furnace, which can be quickly replaced, and the structural device can be quickly replaced, and meanwhile, the replacement method is simple.
The utility model adopts the technical scheme that the simple gun nozzle structure of the mud gun of the Europe and metallurgy furnace mainly comprises a mud gun nozzle, a gun nozzle cap seat, a gun nozzle cap, a gun head, a bolt and a flange; the mud gun muzzle is arranged at the front end of a mud gun muzzle of an European smelting furnace, a mud outlet hole is formed in the center of the mud gun muzzle, the size of the mud outlet hole is the same as that of the mud gun muzzle, 4 internal thread holes are formed simultaneously and used for being connected with a muzzle cap base, the muzzle cap base is in a circular ring shape, and a bolt penetrates through the 4 boss holes and is fastened on the mud gun muzzle; the inside center of big gun muzzle cap base is established out the mud hole, and is the same with mud big gun muzzle play mud hole size, sets up 2 groups forked tail recesses on the big gun muzzle cap base, bilateral symmetry, the big gun muzzle cap be the ring form, the mud hole is established at inside center, is the same with big gun muzzle cap base play mud hole size, sets up 2 groups forked tail bosss on the big gun muzzle cap, bilateral symmetry, big gun muzzle cap base passes through with the big gun muzzle cap forked tail recess and forked tail boss cooperation installation together.
The utility model achieves its functionality through the following combined installation process. The gun nozzle of the clay gun is connected with the gun head through a flange by a bolt to serve as a non-replaceable permanent part. The gun nozzle cap base is connected with the clay gun nozzle through an internal thread bolt, and a dovetail groove is formed in the upper portion of the gun nozzle cap base. The gun nozzle cap is provided with a dovetail groove boss. During installation, a boss on the upper portion of the gun nozzle cap is placed in a groove on the upper portion of the gun nozzle cap base, the gun nozzle cap base and the gun nozzle cap base are mutually meshed and assembled, tight interference assembly is adopted, and the assembled type can be assembled by knocking of a heavy hammer, so that the fastening purpose is achieved. After the utility model is adopted, the field maintenance workload is obviously reduced, and the consumption quantity, weight and cost of the easily damaged parts are greatly reduced. The utility model has the advantages of low cost, simplicity, reliability, wide application range, easy quick replacement, no influence on the tapping time of the European smelting furnace and the like.
Drawings
The utility model will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic front view of the present invention.
Detailed Description
A simple gun nozzle structure of a mud gun of an Ou metallurgical furnace is shown in figure 1 and mainly comprises a mud gun nozzle 1, a nozzle cap base 2, a nozzle cap 3, a gun head 4, a bolt 5 and a flange 6; the mud gun nozzle 1 is connected with the gun head 4 through a flange 6 by a bolt, the mud gun nozzle 1 is arranged at the front end of the mud gun nozzle 4 of the Europe metallurgy furnace, a mud outlet hole is formed in the center of the interior of the mud gun nozzle 1, the size of the mud outlet hole is the same as that of the gun head 4, 4 internal thread holes are formed simultaneously and used for being connected with the gun nozzle cap base 2, the gun nozzle cap base 2 is in a circular ring shape, and the bolt 5 penetrates through the 4 boss holes and is fastened on the mud gun nozzle 1; the mud hole is established at the inside center of big gun nozzle cap base 2, and is the same with 1 mud hole size of mud gun nozzle of mud gun, sets up 2 groups forked tail recesses on the big gun nozzle cap base 2, bilateral symmetry, big gun nozzle cap 3 be the ring form, the mud hole is established at inside center, and is the same with 2 mud hole sizes of big gun nozzle cap base, sets up 2 groups forked tail bosss on the big gun nozzle cap 3, bilateral symmetry, big gun nozzle cap base 2 passes through with big gun nozzle cap 3 forked tail recess and forked tail boss cooperation install together. Because only the gun nozzle cap 3 is easy to burn out during operation of the mud gun, only the gun nozzle cap 3 needs to be replaced when the gun nozzle cap 3 is burnt out. The gun nozzle cap 3 is light in weight and easy to replace, the gun nozzle needs 2 hours to 3 hours and 2 professionals in the past, meanwhile, the gun nozzle is not easy to replace in quality, only 5-10min is needed for replacing the gun nozzle cap 3 after improvement, only 1 person is needed for general stokehole operators, and time, resources, material resources and manpower are saved.
