Description
Technical field
The utility model belongs to blast furnace ironmaking equipment technical field, belongs to stokehold stifled iron notch equipment technical field further, and be specifically related to a kind of structure simply, easy and simple to handle, use safety, is convenient for changing the stokehold Hydraulic clay gun big gun mouth structure of tin hat.
Background technology
In blast furnace ironmaking is produced, current stokehold stifled iron notch generally uses Hydraulic clay gun, and is provided with tin hat in Hydraulic clay gun front end.Before the State of Blast Furnace of prior art, the tin hat of Hydraulic clay gun adopts the mode of Fixed latches to be fixed on big gun mouth; when tin hat damage needs to change; because tumbler pin expanded by heating is difficult to pull down, the difficulty of stokehold replacing tin hat, workload and labour intensity are increased.And Hydraulic clay gun tin hat very easily damages, make the replacing of tin hat very frequent, if change bad in the short period of time, will affect normal stifled iron notch, cause iron mouth to spray greatly, blast furnace will be forced to slow wind, damping down, have a strong impact on carrying out smoothly of blast fumance; Be unfavorable for that carrying out of effect work is created in energy-saving and cost-reducing and volume increase, add the production cost of enterprise, have impact on the economic benefit of enterprise.For this reason, research and develop a kind of structure simple, easy and simple to handle, use safety, the stokehold Hydraulic clay gun big gun mouth structure being convenient for changing tin hat is the key addressed this problem.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, and easy and simple to handle, use safety, is convenient for changing the stokehold Hydraulic clay gun big gun mouth structure of tin hat.
The purpose of this utility model is achieved in that and comprises Hydraulic clay gun body, big gun mouth, tin hat, and the front end of described Hydraulic clay gun body arranges big gun mouth; Outside described big gun mouth, tin hat is set on the surface; Described big gun mouth arranges tumbler pin; Described tin hat arranges bayonet socket; Described tumbler pin and the bayonet fittings of tin hat; Described tin hat arranges drive pin.
The utility model arranges tumbler pin on big gun mouth, and tin hat arranges " L " type bayonet socket, " L " type bayonet fittings on tumbler pin and tin hat; Meanwhile, tin hat arranges drive pin.The utility model is when changing big gun mouth tin hat, the drive pin on tin hat is struck with hammer, big gun mouth tin hat is exited from big gun mouth, whole Renewal process simple and fast, just can more finish changing in short period of time, normal stifled iron notch can not be affected, avoid that iron mouth sprays greatly, blast furnace will be forced to the phenomenon of slow wind, damping down, ensure that carrying out smoothly of blast fumance; Be conducive to energy-saving and cost-reducing and increase production carrying out of wound effect work, reducing the production cost of enterprise, improve the economic benefit of enterprise.The utility model structure is simple, easy and simple to handle, use safety, can the tin hat of Hydraulic clay gun mouth before rapid-assembling/disassembling State of Blast Furnace.
