Abstract
The utility model discloses an Ou ye stove coal-injection gun peephole device, include the mounting flange who sets up in Ou ye stove coal-injection gun peephole department, be about the interval level on the mounting flange and setting up peephole sleeve pipe and coal-injection gun sleeve pipe, install the plug valve on two sleeve pipes respectively, the sealing cap is being installed through the sealing washer to coal-injection gun sheathed tube outside end, and peephole glass is being installed through the hole cap to peephole sheathed tube outside end. The utility model discloses can solve during the ou ye stove tuyere coal injection oxygen rifle and seal and peep the observation problem.
Description
Technical Field
The utility model relates to a peephole device of a coal injection gun of an Ou smelting furnace.
Background
The tuyere sight glass used in the Ou-Meta furnace at present is arranged on the outer end face of the tuyere for blowing oxygen into the Ou-Meta furnace, and the combustion state of the inner end face (in the furnace) of the tuyere can be observed through the tuyere sight glass. According to the requirements of the production process, the position of the original observation hole is changed into the inlet of the pulverized coal injection pipeline. In practical production, the coal injection gun is inserted from the position and directly extends into the inner end surface of the tuyere. This causes that the original function of the tuyere peep hole cannot be used, and the combustion state of the inner end face of the tuyere cannot be directly observed, thereby influencing the judgment of production operators.
Disclosure of Invention
An object of the utility model is to provide an Ou smelt stove coal injection gun peephole device can solve the sealed and peep the observation problem of oxygen rifle in the Ou smelt stove wind gap coal injection.
The technical scheme for realizing the aim is that the peephole device for the coal injection gun of the eustachian furnace comprises an assembly flange arranged at the peephole of the coal injection gun of the eustachian furnace, a peephole sleeve and a coal injection gun sleeve are horizontally arranged on the assembly flange at an upper interval and a lower interval, plug valves are respectively arranged on the two sleeves, a sealing cap is arranged at the outer side end of the coal injection gun sleeve through a sealing ring, and peephole glass is arranged at the outer side end of the peephole sleeve through a hole cap.
A compression screw tap sleeve is used for compressing and sealing on an intersecting surface of a joint part of an oxygen lance flange of an oxygen tuyere and a coal injection lance, and a peephole plug valve and a peephole are arranged at an intersecting point of the central axis of a tuyere small sleeve and the symmetrical axis of a sealing flange, so that the problems of coal injection and tuyere peeping can be solved.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
The utility model provides an Ou smelt stove coal-injection gun peephole device, as shown in figure 1, include the mounting flange that sets up in Ou smelt stove coal-injection gun peephole department, be about on the mounting flange that interval level is setting up peephole sleeve pipe 7 and coal-injection gun sleeve pipe 3, install plug valve 8, 4 on two sleeve pipes respectively, the seal cap 1 is being installed through sealing washer 2 to coal-injection gun sleeve pipe 3's outside end, peephole glass 6 is being installed through hole cap 5 to peephole sleeve pipe 7's outside end. After the tuyere coal injection gun is inserted, the combustion state in the furnace can still be clearly observed, and a reference basis is provided for the judgment of an operator.
