Detailed Description

For the related technical personnel to more clearly understand the technical scheme of the utility model, the utility model will now be described in further detail with reference to the attached drawings.

Example 1

In the embodiment, the upper air inlet aluminum alloy furnace end is mainly formed by assembling four main parts, namely a furnace end base, a furnace end upper cover, a large air inlet pipe inner plug large inverted cone and a small air inlet pipe inner plug small inverted cone, wherein the furnace end base is composed of an inner ring fire cavity 1 and an outer ring fire cavity 2 which are coaxial, a first injection channel 5 and a second injection channel 6 are arranged on the outer peripheral wall of the furnace end base, the first injection channel 5 is communicated with the inner ring fire cavity 1, the second injection channel 6 is communicated with the outer ring fire cavity 2 and a gas channel 14, the furnace end base is provided with a bottom plate 7, a boss 10 is formed by upward protruding inside the bottom plate 7, a positioning ring 12 is sleeved on the periphery of the boss 10, the positioning ring 12 is formed by downward extending of a circular seat plate 8 arranged at the bottom of the furnace end upper cover or upward extending of the bottom plate 7, the top end of the boss 10 is provided with an installation surface 11, by adopting the process design of integrally forming the inner ring fire cavity 1 and the mounting surface 11, the inner ring airflow can be prevented from diffusing outwards. The middle part of the circular base plate 8 is provided with an opening sleeve which is arranged on the inner ring fire cavity 1, the inner ring fire cavity 1 and the outer ring fire cavity 2 are arranged between the mounting surface 11 and the inner part of the circular base plate 8, a screw hole 9 is formed in the mounting surface 11, the circular base plate 8 is tightly attached, the attaching surface is smooth and flat, 3 or 5 the bolt passes through the screw hole 9, the mounting surface 11 and the circular base plate 8 are fastened up and down, the tightness is high, and the gas leakage risk is small. In the bolt fixing process, the positioning ring 12 sleeved on the boss 10 limits the lateral displacement of the circular seat plate 8 and the mounting surface 11, so that the positions are relatively fixed, the mounting operation is facilitated, and the external ring air flow is effectively limited from diffusing inwards.

The number of the bolts is three or five, and the bolts are uniformly distributed. The installation process that the bolt is more complicated and installation cost improves, and quantity is less to be unfavorable for the firm connection of circular bedplate 8 and installation face 11 again, leads to outer ring air current to get into between the interior outer fire chamber through the gap that circular bedplate 8 and bottom plate 7 cooperation formed, leads to the cross fire easily.

The bottom plate 7 upwards extends and forms

lower periphery wall

3, 3 upper end inboards of periphery wall have protruding edge 13 along radially being formed with down, protruding edge 13 and 3 medial surfaces of lower periphery wall laminate with terminal head upper cover's upper peripheral wall 4 lower terminal surface and lateral surface mutually respectively, support and fix a position upper peripheral wall 4 and carry out laser welding, and laser welding is fixed firm, and the leakproofness is strong, and the separation is gaseous outwards to be leaked, prevents to threaten user's safety production.

In another embodiment, the upper end surface of the lower peripheral wall 3 is matched with the lower end surface of the upper peripheral wall 4 of the furnace end upper cover, is in threaded connection and is fixed through laser welding, so that the assembly clearance of the internal thread and the external thread is effectively eliminated, and the gas leakage is prevented.

The furnace end base with the furnace end upper cover all adopts aluminum alloy material die-casting shaping. Has the advantages of low cost, light weight and the like.

Example 2

The second embodiment differs from the first embodiment only in the following ways:

the inner portion of the circular base plate 8 extends downwards to form a boss 10, positioning rings 12 are sleeved on the periphery of the boss 10, the positioning rings 12 are formed by downward extension of the circular base plate 8 or upward extension of the bottom plate 7, an installation face 11 is arranged at the top of the boss 10, the boss is located between the inner ring fire chamber 1 and the outer ring fire chamber 2, the installation face 11 and the bottom plate 7 are internally provided with screw holes 9, and the bolts pass through the screw holes 9 to fasten the installation face 11 and the bottom plate 7. This kind of embodiment can reach the fastening effect equally, and effective separation outer ring air current gets into between the interior outer fire chamber through the gap that circular bedplate 8 and bottom plate 7 cooperation formed, reduces the emergence of the phenomenon of mixing of flames of a fire.

The utility model aims at the problems of complex processing technology, higher cost and the like of the integrally formed furnace end, and ensures the sealing performance while adopting the design of the split furnace end, and the improvement of the sealing performance mainly comprises that firstly, an inner ring fire cavity 1 is integrally formed on a furnace end base to block the inner ring air flow from leaking; secondly, a furnace end base and a furnace end upper cover are fixed between the inner ring fire cavity 1 and the outer ring fire cavity 2 through bolts, so that outer ring airflow is independent relative to inner ring airflow, and the phenomenon that the outer ring airflow enters between the inner and outer fire cavities through a gap formed by matching the circular base plate 8 and the bottom plate 7 to cause fire crossing is reduced; and, periphery wall 3 and furnace end upper cover upper peripheral wall 4 cooperation laser welding under the furnace end base, it is fixed firm, the separation gas leaks to the atmosphere in.

What has been described above is merely a preferred embodiment of the present invention. It should be noted that, for a person skilled in the art, several modifications and variations can be made without departing from the principle of the invention, which is also considered as the protection scope of the invention.
