Abstract
The invention discloses a blast furnace cooling wall inner surface spraying device and relates to a blast furnace cooling wall restoring device. The device solves the problem that when the blast furnace cooling wall is damaged, the cooling wall can only be replaced but can not be restored. The device comprises a cavity body, wherein a spraying nozzle is arranged at the front end of the cavity body, an end cover is arranged at the rear end of the cavity body, an electric conduction spraying nozzle and a compressed air spraying nozzle are respectively arranged inside the cavity body, a handle is also arranged below the cavity body, the electric conduction spraying nozzle is connected with a conductive contact, the compressed air spraying nozzle is connected with a compressed air conveying pipe, and a splashing prevention shield is also arranged at the position of the spraying nozzle and in a horn shape. On the premise that the service life of the blast furnace cooling wall is prolonged, the blast furnace repairing time is shortened, the repairing cost is reduced, and the economic benefit is improved.
Description
Technical field
the present invention relates to a kind of blast furnace cooling stave prosthetic appliance, specifically a kind of spray equipment that is used for the blast furnace cooling stave inner surface.
Background technology
The blast furnace that
metallurgy industry is used to smelt iron, its body of heater need can the water flowing cooling cooling wall protect.Because wearing and tearing just can take place or corrode in continuity and continuation that blast furnace is produced, its cooling wall inner surface inevitably.After the cooling wall inner surface suffered erosion even is damaged, conventional method was to change, yet blast furnace is changed cooling wall, not only a large amount of occupied funds, and need the quite long off-time, therefore, can have a strong impact on the business economic benefit.
Summary of the invention
the object of the present invention is to provide a kind of spray equipment that is used for the blast furnace cooling stave inner surface, solve can only change the problem that can not repair after blast furnace cooling stave damages.
the technical solution adopted for the present invention to solve the technical problems is: a kind of spray equipment that is used for the blast furnace cooling stave inner surface, it is characterized in that, and comprise cavity; The cavity front end is provided with nozzle; The rear end is provided with end cap, is respectively equipped with conduction nozzle and compressed-air atomizer in the cavity, and the below of cavity also is provided with handle; Described conduction nozzle is connected with conductive contact, and compressed-air atomizer links to each other with blowpipe; Also be provided with splash guard at the nozzle place, it is horn-like that splash guard is.
the invention has the beneficial effects as follows: prolonging under the remaining cooling wall of the blast furnace prerequisite in service life, shorten the blast furnace repairing time, reduce repair cost, increase economic efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among
figure: 1 cavity, 2 nozzles, 3 bonnets, 4 conduction nozzles, 5 compressed-air atomizers, 6 handles, 7 conductive contacts, 8 blowpipes, 9 splash guards.
The specific embodiment
are as shown in Figure 1, and a kind of spray equipment that is used for the blast furnace cooling stave inner surface comprises cavity 1; Cavity 1 front end is provided with nozzle 2; The rear end is provided with end cap 3, is respectively equipped with conduction nozzle 4 and compressed-air atomizer 5 in the cavity 1, and the below of cavity 1 also is provided with handle 6; Described conduction nozzle 4 is connected with conductive contact 7, and compressed-air atomizer 5 links to each other with blowpipe 8; 2 places also are provided with splash guard 9 at nozzle, and splash guard 9 is horn-like.
in use; Through wire-feed motor the alloy silk is sent in the conduction nozzle 4; Conductive contact 7 links to each other with power supply, and energising back alloy silk is in the fusing of the end of conduction nozzle 4, and the high speed Compressed Gas passes through blowpipe 8 through compressed-air atomizer 5 ejections; Alloy silk after the fusing atomizes under compressed-air actuated effect and sprays to through nozzle 2 and forms coating on the working face, thereby realizes the reparation to blast furnace cooling stave.For the alloy silk that prevents in spraying process, to atomize splashes, 2 places also are provided with splash guard 9 at nozzle.The staff can hold handle 6 and operate, and very convenient easy row can be repaired fast, prolongs the service life of blast furnace cooling stave.
