Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Specific examples are given below.
Referring to fig. 1-5, the present invention provides a ceramic protective lining for a wind guide ring of a vertical mill, which comprises a positioning plate 1; a bottom plate 3 is fixedly connected to one side of the positioning plate 1; three sides of the bottom plate 3 are folded, and a dovetail strip 5 is fixedly connected to the surface of one side of the bottom plate 3; the dovetail strips 5 are connected with a plurality of groups of dovetail ceramics 4 in a sliding manner; the adjacent surfaces of a plurality of groups of dovetail ceramics 4 are attached and cover the surface of the base; the other side surface of the bottom plate 3 is fixedly connected with a connecting plate 2 and a reinforcing rib 8 respectively; the connecting plate 2 is welded at one side end part of the bottom plate 3; the reinforcing ribs 8 are welded to the middle of the surface of the bottom plate 3.
When the wear-resistant layer is in work, the traditional wear-resistant layer has poor wear resistance, namely after a period of time, a surfacing layer on the surface of the sheath is worn, and then the machine is stopped to perform surfacing on a new wear-resistant layer, so that the mode has long downtime, high labor intensity, small internal space of a vertical mill, poor light, extremely-high operation and more inconvenient potential safety hazards; if the device is detached for welding, the maintenance and installation period is long, the production progress is greatly influenced, and the device is also cast by high manganese steel and other materials, so that the whole device is heavy, the whole load on the device is large, and the anti-abrasion effect is poor; therefore wind-guiding ring ceramic bushing who proposes in the device, through using the traditional wearing layer of ceramic replacement, can improve the wear resistance of this wind-guiding ring bushing, and simultaneously, utilize the bottom plate 3 of three sides hem to carry out the bearing to multiunit forked tail porcelain 4, treat forked tail porcelain 4 installation back, at welding rod 6, make multiunit forked tail porcelain 4 can closely laminate on bottom plate 3, and receive bottom plate 3's bearing effect, forked tail porcelain 4 through the inseparable concatenation of multiunit, can make the material whole contact with forked tail porcelain 4 and unable wearing and tearing bottom plate 3, on full play forked tail porcelain 4's wear resistance basis, can also avoid bottom plate 3 to receive wearing and tearing and lead to ceramic fracture and drop, and forked tail porcelain 4's quality is for metal material such as high manganese steel, it has more light advantage, consequently can not lead to the whole influence that causes the overweight of load to equipment, wherein, forked tail porcelain 4 adopts the dual mode temperature resistant of mechanical high temperature glue to prevent that the pottery from droing.
Preferably, the positioning plates 1 are provided with two groups, and the through holes are formed in the two groups of positioning plates 1.
The during operation, 1 symmetrical arrangement of two sets of locating plates utilizes external bolt to run through the through-hole and can be connected it and found the mill barrel and form a whole circle, and with found the mill barrel and become a contained angle (back taper) at a certain orientation center to with the wind direction found mill barrel center, also will found mill central grinding roller grinding and the material that splashes rebound immediately at a glance center, the protection is mainly that the protection is found the mill barrel and is not worn and torn by the impact of the material that splashes.
Preferably, three groups of dovetail strips 5 are arranged, and welding grooves 51 are formed in the three groups of dovetail strips 5.
During operation, three groups of dovetail strips 5 are arranged, and the welding grooves 51 arranged in the three groups of dovetail strips 5 can be used for welding the dovetail strips 5 on the bottom plate 3.
Preferably, a dovetail groove 41 is formed in the bottom surface of the dovetail porcelain 4 corresponding to the dovetail strip 5, and an embedded groove 42 is formed in the bottom surface of the dovetail porcelain 4 corresponding to the folded edge of the bottom plate 3; the inner embedded groove 42 is matched with the folded edge of the bottom plate 3.
The during operation, forked tail porcelain 4 is connected through the joint mode with dovetail 5, and when installation forked tail porcelain 4, need with 4 sliding connection of forked tail porcelain on dovetail 5, and multiunit forked tail porcelain 4 is located same group dovetail 5, the laminating of its adjacent limit, and forked tail porcelain 4 is when the preparation, caulking groove 42 in its lateral wall setting needs, with this inseparable laminating on bottom plate 3, wherein forked tail porcelain 4 all adopts diamond sand line blank cutting technology preparation, the usable high temperature super glue of adjacent forked tail porcelain 4 is fixed when the installation.
Preferably, a welding strip 6 is welded on the bottom plate 3 at a position different from the three side folded edges, and the welding strip 6 is matched with the embedded groove 42 on the dovetail porcelain 4.
During operation, the welding strip 6 that the floor went upward to set up is used for carrying out final welding to the bottom plate 3 of three side hems, promptly after 4 whole installations of forked tail porcelains, utilizes welding strip 6 welding on bottom plate 3, realizes fixing forked tail porcelains 4.
The working principle is as follows: because the existing traditional wear-resistant layer has poor wear resistance, namely after a period of time, a surfacing layer on the surface of the sheath is worn, and then a new wear-resistant layer is subjected to surfacing operation after shutdown, the mode has long shutdown time, high labor intensity, small internal space of the vertical mill, poor light, extremely-high operation and inconvenience and many potential safety hazards; if the device is detached for welding, the maintenance and installation period is long, the production progress is greatly influenced, and the device is also cast by high manganese steel and other materials, so that the whole device is heavy, the whole load on the device is large, and the anti-abrasion effect is poor; therefore, the air guide ring ceramic lining provided by the device can improve the wear resistance of the air guide ring lining by replacing a traditional wear-resistant layer with ceramic, meanwhile, the bottom plate 3 with three folded edges supports a plurality of groups of dovetail ceramics 4, after the dovetail ceramics 4 are installed, welding strips 6 are welded to enable the plurality of groups of dovetail ceramics 4 to be tightly attached to the bottom plate 3 and to be subjected to the bearing effect of the bottom plate 3, all materials can be in contact with the dovetail ceramics 4 through the plurality of groups of closely spliced dovetail ceramics 4 to avoid abrasion of the bottom plate 3, and on the basis of fully exerting the wear resistance of the dovetail ceramics 4, the bottom plate 3 can be prevented from being abraded to cause ceramic cracking and falling off, and the quality of the dovetail ceramics 4 is lighter compared with metal materials such as high manganese steel, so that the influence of overload on the whole equipment can be avoided;
wherein, two sets of locating plates 1 symmetrical arrangement utilizes external bolt to run through the through-hole and can be connected it with the upright mill barrel and form a whole circle, and with the contained angle that becomes orientation center immediately, so that with the wind volume direction immediately mill barrel center, also will immediately grind the material that central grinding roller grinding of mill and splashes and rebound immediately no easy center, and the back lining mainly protects immediately that the mill barrel does not receive the impact of the material that splashes and wearing and tearing.
