Abstract
The invention relates to a burner, in particular to a coal dust burner which is provided with a wearable lining plate at the coal dust entrance and applied to industrial and civil kilns. The burner comprises a coal dust central pipe and a coal dust circumference pipe; the external wall of the coal dust central pipe is provided with a U-shaped wearable lining plate which is fixed on the external surface of positions of the coal dust central pipe directly washed by screws; the wearable lining plate is an embedded prefabricated structure, with an external layer of cover-shaped steel structure and the internal layer of pouring wearable material; and the pouring wearable material is directly poured in the external layer of cover-shaped steel structure. The burner has the advantages that the service life of the coal dust burner is effectively prolonged; the wearable lining plate is easy to be replaced when being prepared as the prefabrication structure; and when the wearable lining plate is severely abraded, the wearable lining plate can be removed and replaced by the standby which is prepared in advance in an extremely short time.
Description
Technical field
The present invention relates to a kind of burner, the coal powder entrance place that uses on particularly a kind of industry and the civilian kiln has the coal burner of abrasion-proof backing block.
Background technology
The coal powder entrance place that on existing industry and the civilian kiln with the coal dust is the burner of fuel is made of the ordinary steel structure, it is the weak link of whole burner, owing to directly washing away of the high velocity air that contains coal dust, after making that burner comes into operation, this place on every side and the tube wall at center is very fast is pierced, cause shorten greatly the service life of burner, influence the normal use of burner.Though the tube wall that the burner that has will be located thickening or employing abrasion-proof backing block, make prolong to some extent service life, but effect is not very good, and because abrasion-proof backing block and tube wall are combined as a whole, need during maintenance whole burner dismounting back is repaired, need the plenty of time, have a strong impact on the ordinary production of kiln.
Summary of the invention
For overcoming the defective of prior art, the purpose of this invention is to provide a kind of coal burner that has abrasion-proof backing block, this abrasion-proof backing block can improve the service life of coal burner, and abrasion-proof backing block is wear-resisting precast construction, be easy to change, wearability is good, can shorten maintenance time, avoids influencing the ordinary production of kiln.
For achieving the above object, the present invention is achieved through the following technical solutions:
The coal burner that has abrasion-proof backing block, this burner comprise coal dust central tube and coal dust peripheral tube, and the outer wall of described coal dust central tube is provided with abrasion-proof backing block, and this abrasion-proof backing block is fixed on the outer surface that the coal dust central tube is subjected to directly to wash away the position by screw.
Described abrasion-proof backing block is a U type structure.
The both sides of described coal dust peripheral tube are subjected to directly to wash away the position respectively an installing hole, and abrasion-proof backing block is by being bolted on the installing hole; This abrasion-proof backing block is inserted precast construction, and skin is to cover formed steel construction, and internal layer casts directly in the outer cover formed steel construction for cast high-abrasive material, cast high-abrasive material.
The internal layer working face of described abrasion-proof backing block is curved, and is corresponding with the installing hole of coal dust peripheral tube both sides.
Be welded with the anchoring piece that is used for fixing internal layer cast high-abrasive material on the described lid formed steel construction equably.
Described anchoring piece adopts staggered mode to be welded on and covers on the formed steel construction.
Compared with prior art, the invention has the beneficial effects as follows:
1, rational in infrastructure, the material of abrasion-proof backing block suit, and have effectively prolonged the service life of coal burner.
2, abrasion-proof backing block is made precast construction, is easy to change, and after abrasion-proof backing block heavy wear, only needs it is pulled down, and the preprepared spare part is changed to get final product again, and required time is very short.

The specific embodiment
See Fig. 9, Figure 10; the coal burner that has abrasion-proof backing block; this burner comprises coal dust central tube 1 and coal dust peripheral tube 4; the outer wall of coal dust central tube 1 is provided with abrasion-proof backing block 2 (Fig. 1, Fig. 2, Fig. 3, Fig. 4); this abrasion-proof backing block is " U " type baffle that adopts suitable high-abrasive material to make, and this abrasion-proof backing block 2 is fixed on the outer surface that coal dust central tube 1 is subjected to directly to wash away the position by screw 3.
See Fig. 5, Fig. 6, coal dust peripheral tube abrasion-proof backing block is a precast construction, and the both sides that are embedded in the coal dust peripheral tube 4 of burner are subjected to directly to wash away on the installing hole 11 at position.Its skin is a blind flange 7 made from steel plate, and internal layer is the cast high-abrasive material, and the internal layer working face is curved.Evenly weld " V " shape anchoring piece 6 (Fig. 7, Fig. 8) by certain density on the blind flange 7, be used for fixing wear-resistant castable 5.
Be subjected to directly to wash away the position in the both sides of the coal dust peripheral tube 4 of burner and respectively do an installing hole 11, the end of installing hole 11 is provided with mounting flange 10 (Figure 10), and blind flange 7 is docked with mounting flange 10, and is fixing by bolt 8 and nut 9.During making, flange 10 and blind flange 7 are smooth, and the compact dimensions of wear-resistant castable 5 is wanted precisely, and want accurately the installation site of installing hole 11 and abrasion-proof backing block 2, and the abrasion-proof backing block after could guaranteeing like this to install has good wear-resisting effect.
Because abrasion-proof backing block has adopted rational structure and suitable wear-resistant material, has had good wearability, and all be installed in burner directly washed away the position, this position tightly protected, thereby prolonged the service life of burner effectively.In addition, because the abrasion-proof backing block of central tube and peripheral tube is all made preform structure, be easy to change, after abrasion-proof backing block heavy wear, only need be pulled down it, the preprepared spare part are changed to get final product again, required time is very short, influences the ordinary production of kiln hardly.
