Abstract
The utility model discloses a wear resistant elbow; a shell body is arranged on the outer surface of the elbow, a packing cavity is formed between the shell body and the elbow, a packing hole is arranged on the surface of the shell body, and wear resistant material is filled in the packing cavity. As the shell body filled with the wear resistant material is arranged on the elbow, compared with the common elbow, the service life of the wear resistant elbow is prolonged by multiple times, and the resistance to the smoke flowing is not increased, the production technology is simple and the application is wide.
Description
Technical field
The utility model relates to a kind of channel bend, is specifically related to be used in a kind of dusting apparatus the wear-resistant bend that flue gas is carried.
Background technique
The flue gas of enterprises such as power plant, steel mill, mine, building materials is handled multipurpose pipe and is carried; Contain abrasiveness exhaust gas dust or particle in the above-mentioned flue gas; When dust is carried in horizontal pipe and vertical pipe; The working angle of particle and tube wall is very little, so straight pipe wall can not cause serious wearing and tearing because of the use of short time.When particle got into elbow, because the change of moving direction receives the effect of centrifugal force and inertial force, the particle with certain mass can wash away tube wall with the mode of jet, and channel bend was worn through in very short time.
In the existing technology, the most frequently used method is to adopt high-abrasive material that the position that is hit is thickeied in advance, and high-abrasive material often adopts wear-resisting steel plate or wear-resistant ceramic, but can not effectively prolong elbow working life through the actual above method of proof of using.
The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, designs a kind of elbow structure, and this structure can guarantee that the elbow wear-resisting property is excellent, thereby prolongs the working life of elbow.
For realizing above-mentioned purpose; The technological scheme of the utility model has provided a kind of wear-resistant bend; The outer surface of said elbow is provided with housing, constitutes packing cavity between said housing and the elbow, and the surface of said housing is provided with feeding port; Be filled with high-abrasive material in the said packing cavity, said high-abrasive material is corundum castable, alumina cement or grouting lime solidification material.
Corresponding with the position of flue gas particle bump elbow tube wall in order to guarantee the elbow housing parts, on the cross section of said elbow, the scope that packing cavity coats elbow is not less than 2/3 of elbow tube wall girth.
In order to prolong the wearing-in period of elbow tube wall, the elbow tube wall relative with said packing cavity is the arc thickened wall.
The advantage and the beneficial effect of the utility model are: owing to be provided with the packing cavity that is filled with high-abrasive material on this elbow, comparing the life-span with common elbow can increase several times, and does not increase the resistance of flow of flue gas, and production technology is simple, is widely used.
Description of drawings
Fig. 1 is the utility model wear-resistant bend embodiment's a structural representation;
Fig. 2 is the structural representation in A-A ' cross section of Fig. 1.
Among the figure: 1, elbow; 2, housing; 3, packing cavity; 4, feeding port; 5, grouting lime solidification material; 6, arc thickened wall.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technological scheme of the utility model, and can not limit the protection domain of the utility model with this.
Embodiment
As shown in Figure 1; Wear-resistant bend comprises elbow 1; The outer surface of said elbow 1 is provided with housing 2, constitutes packing cavity 3 between said housing 2 and the elbow 1, and said housing 2 surfaces are provided with feeding port 4; Be filled with high-abrasive material grouting lime solidification material 5 in the said packing cavity 3, the tube wall of the elbow 1 relative with said packing cavity 3 is an arc thickened wall 6.
As shown in Figure 2, the packing cavity cross section on wear-resistant bend A-A ' cross section is open annular, and opening angle is 120 °.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
Claims (4)
1. a wear-resistant bend is characterized in that, the outer surface of said elbow is provided with housing, constitutes packing cavity between said housing and the elbow, and the surface of said housing is provided with feeding port, is filled with high-abrasive material in the said packing cavity.
2. wear-resistant bend as claimed in claim 1 is characterized in that, on the cross section of said elbow, the length of curve that said packing cavity and elbow tube wall join is not less than 2/3 of elbow tube wall girth.
3. wear-resistant bend as claimed in claim 1 is characterized in that, said high-abrasive material is corundum castable, alumina cement or grouting lime solidification material.
