Description
Technical field
The utility model relates to a kind of wear-resistant bend carrying coal slirne pipeline, belongs to by Pipeline transport coal slirne technical field.
Background technique
At present, in coal washery, mine, be a kind of common coal slirne transporting pattern by Pipeline transport coal slirne, because the flowing velocity of coal slirne is very fast, washes away tube wall, be easy to cause wearing and tearing, particularly the bend part of pipeline, it is particularly serious to wash away the wearing and tearing caused.For addressing this problem, people use high-abrasive material to make pipeline and elbow, but conventional wear-resistant bend mostly is and waits gauge structure, and need adopt expensive high-abrasive material, cost is higher, and generally, life cycle is shorter, equipment maintenance cost is higher for wear-resisting property.Somebody improves elbow structure, such as: Chinese utility model patent 200420150695.3,201220103480.0,201220629583.0 disclosed " wear-resistant bend ", adopt spherical structure, the diameter of spherical structure is 1.5-4 times of pipeline diameter; This kind of spherical elbow because the position of the centre of sphere is unreasonable, spherical diameter is excessive (think: spherical diameter is larger, wear-resisting property better by background technique, belong to technology prejudice), its wear-resisting property is general, because spherical diameter is excessive, not only waste material, raise the cost, and it is large to take up room, causes construction, difficult in maintenance; In addition, the two ends straight tube form right angle elbow of above-mentioned spherical elbow, the position of two straight tubes curved intersection in elbow is dealt with improperly, is easy to cause wearing and tearing, a considerable amount of spherical elbow in scene, is all that the position of two straight tubes curved intersection in elbow is damaged.
Model utility content
The utility model object is to provide a kind of wear-resistant bend carrying coal slirne pipeline, rationally determine sphere center position and the diameter of spherical elbow, the position of two straight tubes curved intersection in elbow is processed, improve wear-resisting property, reduce small product size, reduce costs, be convenient to installation and maintenance, solve the problems referred to above existed in background technique.
The technical solution of the utility model is:
A kind of wear-resistant bend carrying coal slirne pipeline, comprise straight tube one, straight tube two and spherical inner chamber body, straight tube one and straight tube two isometrical, central axis is arranged vertically mutually, spherical inner chamber body is arranged on straight tube one and straight tube two intersection, forms 90 degree of spherical elbows bent.
The centre of sphere of spherical inner chamber body is positioned at the point of intersection of straight tube one and straight tube two central axis; The inner chamber radius of spherical inner chamber body is: the centre of sphere is the distance in elbow between curved crosspoint to straight tube one and straight tube two inwall elongation line.
Straight tube one and straight tube two inwall elongation line curved crosspoint in elbow are provided with arc transition, and the center of circle of arc transition is positioned at: perpendicular to two spherical inner chamber body tangent line crosspoints of straight tube one and straight tube two central axis; The radius of arc transition is: straight tube one and straight tube two inwall elongation line curved crosspoint in elbow, be that diagonal forms square with the spacing in the center of circle of arc transition, the foursquare length of side is the radius of arc transition.
Described straight tube one, straight tube two and spherical inner chamber body, internal surface is provided with ceramic porcelain layer, improves wear-resisting property.
Coal slirne enters spherical inner chamber body by straight tube one, fraction coal slirne moves along spherical inner chamber body inwall, form reflux in spherical inner chamber body inside, the most of coal slirne entering spherical inner chamber body subsequently is directly flushed on the fraction coal slirne of reflux, reduces washing away wear-resistant bend inwall; Coal slirne turns in wear-resistant bend, discharges wear-resistant bend by straight tube two.
Innovative point of the present utility model is sphere center position and the diameter of rationally determining spherical elbow, processes the position of two straight tubes curved intersection in elbow, improves wear-resisting property, reduces small product size.There is technical prejudice in background technique, thinks that the diameter of spherical inner chamber body is larger, wear-resisting property better, but spherical inner chamber body diameter is excessive, and coal slirne knows from experience generation whirlpool at spherical inner chamber, carries out secondary and washes away, add wearing and tearing to spherical inner chamber body.Pass through field observation, the wear-resistant bend of background technique is through straight tube one and the curved crosspoint place damage in elbow of straight tube two inwall elongation line of being everlasting, the utility model determines rational arc transition radius by test, achieve beyond thought technique effect, substantially increase the working life of wear-resistant bend.
For improving the working life of wear-resistant bend, the inwall of wear-resistant bend is provided with porcelain layer.
The utility model is also applicable in cement concrete, particulate dust, liquid containing granule materials conveying.
Good effect of the present utility model is: sphere center position and the diameter of rationally determining spherical elbow, processes the position of two straight tubes curved intersection in elbow, improves wear-resisting property, reduces small product size, reduces costs, be convenient to installation and maintenance; Wear-resistant bend can use cheaper high-abrasive material just can reach good wear-resisting property, shown by site test: compared with the wear-resistant bend of background technique, at use same material, in identical operating conditions situation, the utility model extends more than five times friction durability, effectively solves background technique Problems existing.
