[0002] At present, the main functions of the flow divider cover of the super micro pulverizer are to guide the flow of the pulverized material, to form a semi-closed pulverizing cavity with the pulverizing chamber shell, the hammer and the gear ring, to prevent the pulverized material with large mass from being dispersed to the invalid pulverizing area, to prevent the pulverized material not meeting the fineness requirement from moving away from the hammer and the gear ring to reduce the pulverizing efficiency, and to break the flow layer and increase the impact frequency of the material by the flow divider cover rib plate.

[0003] Since the current flow divider cover of the super micro pulverizer is of a welded integrated type, the main problem is that the flow divider cover and the flow divider cover rib plate are worn due to the long-time pulverization of the material and the high flow rate of the material, so that the strength of the flow divider cover is weakened, the flow dividing function of the flow divider cover is affected, the impact frequency of the material is reduced, the pulverizing efficiency is reduced, and the overall performance of the equipment is affected.

[0004] In addition, the flow divider cover is worn and the pulverizing chamber is perforated, so that the material leaks from the holes, the pulverizing chamber needs to be replaced, and the cost and workload are greatly increased. Since the inner and outer rings of the flow divider cover are greatly different in wear, in actual production, the wear parts are the outer ring assembly, and the inner ring assembly is almost not worn, so the cost of replacing the entire welded flow divider cover is high, and the replacement process is time-consuming and laborious.

[0030] Example 1

[0031] like Figures 1-7 As shown, the assembled fairing 100 includes an inner ring assembly 110, an outer ring assembly 120, and a stiffener assembly 130.

[0032] The inner ring assembly 110 is conical. The outer ring assembly 120 is cylindrical. The outer ring assembly 120 is assembled and connected to the inner ring assembly 110 via the stiffener assembly 130.

[0033] In one embodiment, the stiffener assembly 130 includes a first stiffener 131, a second stiffener 132, and a connector 133.

[0034] First stiffeners 131 are evenly distributed on the outer side wall of the inner ring assembly 110, and first connecting holes 1310 are provided on the first stiffeners 131. Preferably, there are two first connecting holes 1310, arranged from top to bottom. The first connecting holes 1310 are preferably oblong holes. In one embodiment, the first stiffeners 131 are trapezoidal; the oblique waist of the first stiffeners 131 faces the inner ring assembly 110.

[0035] Second stiffening plates 132 are evenly distributed on the inner sidewall of the outer ring assembly 120, and second connecting holes 1320 are provided on the second stiffening plates 132. Preferably, there are two second connecting holes 1320, arranged from top to bottom. The second connecting holes 1320 are preferably circular holes.

[0036] Connector 133 is installed in the mating first connecting hole 1310 and second connecting hole 1320 to achieve an assembly connection between the inner ring assembly 110 and the outer ring assembly 120. Preferably, connector 133 is a bolt, nut, and washer.

[0037] In one embodiment, the upper edge of the outer ring assembly 120 is higher than the upper edge of the inner ring assembly 110; the lower edge of the outer ring assembly 120 is lower than the lower edge of the inner ring assembly 110.

[0038] The utility model discloses a split flow cover and the cooperation installation part (split flow cover outer ring assembly) of pulverizer chamber casing are adjusted from the welding integral type of originally to the split assembly type (split flow cover outer ring assembly and split flow cover inner ring assembly assembly combination) of this technical scheme. Because the wear difference of split flow cover inner and outer rings is very big, in actual production, the wear position is all outer ring assembly, and inner ring assembly hardly wears, therefore the cost of replacing entire welding type split flow cover is higher, and the replacement process is time -consuming and laborious. Therefore, the split assembly type can replace only the outer ring assembly of wear.

[0039] The split flow cover includes a split flow cover outer ring assembly and a split flow cover inner ring assembly. The split flow cover outer ring assembly and the split flow cover inner ring assembly are fixedly installed through a ring of arranged rib plate assemblies and connecting pieces, to ensure that the split flow cover is in the correct position and meets the working requirements.

[0040] When the split flow cover outer ring assembly wears, the split flow cover is taken out, the connecting pieces are removed first, then the split flow cover outer ring assembly is replaced, wherein the split flow cover outer ring assembly rib plate is against the material impact direction, the inner and outer ring assemblies are connected using the connecting pieces, and finally the split flow cover is reset.
