Abstract
The utility model discloses a kind of New type coal rifle structures, including coal injection pipe, wherein one end of coal injection pipe is arranged with the sleeve-type connector to match with it, the port flush of the port of sleeve-type connector and the coal injection pipe, the utility model not only improves working efficiency, reduces production cost, and ensure that product quality significantly, structure is simple, easy to maintain.
Description
Technical field
The utility model relates to coal rifle technical field of structures, particularly relate to a kind of New type coal rifle structure.
Background technique
Coal rifle in the prior art is formed by two stainless-steel pipe welds, and weld has since there are variable diameters
The gradient of very little.During practical coal injection, " raceway zone " of a coal dust zonule formed here causes herein
It being easy to be led to by mill, and then coal rifle is scrapped, coal dust evolution increases the operating pressure of staff, reduces working efficiency, in order to
Improve this status, improve working efficiency, save the cost reduces working strength, and the utility model proposes a kind of New type coal rifles
Structure.
Utility model content
Technical problem to be solved in the utility model is, the shortcomings that for the above prior art, proposes a kind of New type coal
Rifle structure not only improves working efficiency, reduces production cost, and ensure that product quality significantly, structure is simple, maintenance side
Just.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is achieved in the following ways: Yi Zhongxin
Moulded coal rifle structure, including coal injection pipe, wherein one end of coal injection pipe are arranged with the sleeve-type connector to match with it, sleeve-type connector
Port and the coal injection pipe port flush.
The technical solution that the utility model further limits is:
New type coal rifle structure above-mentioned, the length of coal injection pipe are 2200mm, and internal orifice dimension is Φ=15mm, outer aperture be Φ=
25mm。
New type coal rifle structure above-mentioned, the length of sleeve-type connector are 400mm, and internal orifice dimension is Φ=25mm, and outer aperture is Φ
=33mm。
New type coal rifle structure above-mentioned, the joint place between coal injection pipe and sleeve-type connector far from flush one end is using weldering
It is mutually secured to connect connection type.
The beneficial effects of the utility model are: by the technical solution of the utility model, it is originally practical to change the mode of welding
Into the mode for sleeve-type connector, variable diameter can be eliminated in this way, improves the structure of original coal rifle, reduce coal dust to the mill of gun body
Damage is conducive to abridged edition consumption reduction and blast furnace stable smooth operation to increase coal rifle service life, reduces coal rifle mill and leads to, coal dust evolution
Risk, and the technical solution structure is simple, and easy to use, maintenance is simple.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein: 1- coal injection pipe, 2- sleeve-type connector.
Specific embodiment
The utility model is described in further detail below:
Embodiment 1
A kind of New type coal rifle structure provided in this embodiment, including coal injection pipe 1, wherein one end of coal injection pipe 1 be arranged with
Its sleeve-type connector 2 to match, the port of sleeve-type connector 2 and the port flush of coal injection pipe 1；Coal injection pipe 1 and bushing type
Joint place between connector 2 far from flush one end is mutually secured using welding connecting mode；The length of coal injection pipe 1 is 2200mm,
Internal orifice dimension is Φ=15mm, and outer aperture is Φ=25mm；The length of sleeve-type connector 2 is 400mm, and internal orifice dimension is Φ=25mm, exit orifice
Diameter is Φ=33mm.
In this way, by the technical solution of the utility model, this practical side that the mode of welding is improved to sleeve-type connector
Formula can eliminate variable diameter in this way, improve the structure of original coal rifle, reduce abrasion of the coal dust to gun body, so that increasing coal rifle makes
With the service life, be conducive to abridged edition consumption reduction and blast furnace stable smooth operation, reduce coal rifle mill and lead to, the risk of coal dust evolution, and the technology
Scenario-frame is simple, easy to use, and maintenance is simple.
Above embodiments are only to illustrate the technical idea of the utility model, and the protection model of the utility model cannot be limited with this
Enclose, it is all according to the utility model proposes technical idea, any changes made on the basis of the technical scheme each falls within this reality
Within the scope of novel protected.
