Abstract
The utility model belongs to the technical field of pulp pipeline spare parts of mineral separation factories and particularly relates to a wear-resisting elbow for a pulp pipeline. The wear-resisting elbow comprises an elbow body and is characterized in that an elbow ball body is arranged at the turning position between an elbow inlet and an elbow outlet of the elbow body, the pipe wall of the outer side of the elbow inlet is linearly connected with the pipe wall of one side of the elbow ball body, and the outer pipe wall of the other side of the elbow ball body is in corner connection of the pipe wall of the outer side of the elbow outlet. In the same using period, the wear resistance of the pipeline elbow is six to eight times of the wear resistance of a welded and punched elbow. Thus, the wear-resisting elbow can achieve obvious economical benefits, is suitable for bent positions of pulp pipelines in the mineral separation factories and is also suitable for the bent positions of pipelines for conveying other media in industries of metallurgy, chemical engineering, medicine and the like.
Description
Technical field
The utility model belongs to ore dressing plant ore slurry pipeline spare part technical field, particularly a kind of ore slurry pipeline wear-resistant bend.
Background technique
In the ore dressing plant, various ducts and pipes crisscross.Every at corner, pipeline will force medium to change direction, and MEDIA FLOW just produces stronger impact, friction and turbulent flow and causes wearing and tearing tube wall.The elbow that the ore slurry pipeline in present each ore dressing plant uses generally has two kinds, and a kind of is weld ell, and be 1 to 3 months working life, and another kind is punched bend, and be 3 to 6 months working life.What the past generally used is weld ell.Weld ell is to cut pipe to be welded.Welding is just carried out at outer surface, does not generally beat groove, and layer thickness is inequality also, and all less than pipe thickness, so weld joint and tube wall can not the same life-spans, the weld seam of especially outer crook grinds leakage at first.The present common punched bend that used.Although the punched bend no-welding-seam, its outer crook wall is thin, although extend to some extent than weld ell working life, generally also can only reach 5-6 month.This shows, the working life of the various channel bends in ore dressing plant is all very low.Solve the wear-resisting problem of elbow, key position is just in the outer crook of elbow.Because the outer crook of MEDIA FLOW elbow produces stronger impact, friction and turbulent flow and causes wearing and tearing.How reducing or eliminating these wearing and tearing is pendulum large problems in face of us.
Summary of the invention
The utility model proposes a kind of technological scheme, use the special-shaped cast steel wear-resistant bend with special construction, solve the wear-resisting problem of ore slurry pipeline corner, increase various channel bend working life
The ore slurry pipeline wear-resistant bend.
The purpose of this utility model realizes by following technical proposals:
Ore slurry pipeline wear-resistant bend of the present utility model, it is characterized in that: comprise the elbow body, it is characterized in that: be provided with the elbow spheroid at the elbow entrance of described elbow body and the corner between the elbow outlet, the outside tube wall of described elbow entrance and elbow spheroid one side pipe wall linearly shape are connected, and the opposite side outer tube wall of described elbow spheroid is bent angle with the outside tube wall of elbow outlet and is connected.
The utility model has the advantages that: according to hydromechanical character, long-pending in order to strengthen fluid cross-section, reduce flow velocity, can increase static pressure, reduce dynamic pressure and turbulent flow, we expand outwardly the tube wall of the outer crook of elbow, and be designed to spherical, reaching the sectional area that increases outer crook, to reduce the purpose of dynamic pressure and turbulent flow, thereby make MEDIA FLOW directly not impact bend wall, can reduce widely the wearing and tearing that cause because of impact, friction and turbulent flow.Because turbulent flow reduces greatly, thereby only need less power can keep required flow velocity, not only can not increase pipe resistance, and can also reduce the loss of pressure head of MEDIA FLOW, and obtain more stable flow velocity.
The elbow of this structure for delivery of granular material, there is certain granular material in the elbow spheroid that can arrange in the corner of elbow body, can reaches the purpose of material abrasive material, elbow is not is not almost worn and torn.
The utility model is in identical life cycle, the wear resistance of channel bend is welding and punched bend 6 to 8 times, can obtain significant economic benefit, be suitable for using in ore slurry pipeline bending part, ore dressing plant, also can carry in industries such as metallurgy, chemical industry, medicine pipe bending place's use of other media.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Fig. 1, further illustrate mode of execution of the present utility model:
As shown in Figure 1, ore slurry pipeline wear-resistant bend of the present utility model, it is characterized in that: comprise elbow body 2, it is characterized in that: be provided with elbow spheroid 5 at the elbow entrance 3 of described elbow body 2 and the corner between elbow outlet 1, one side pipe wall of described elbow entrance 3 and elbow spheroid 5 outside tube walls linearly shape 4 are connected, and the opposite side outer tube wall of described elbow spheroid 5 is bent angle shape 6 with the outside tube wall of elbow outlet 1 and is connected.
The utility model elbow spheroid 5 centers are on elbow entrance tube chamber center line, and elbow spheroid 5 is in the elbow outlet tube chamber center line outside.The utility model expansion is designed to spherical, is mainly in order to obtain larger volume, and the resistance of media flow is little, thereby wearing and tearing are also minimum.Center, spherical chamber is on elbow entrance tube chamber center line, and center, spherical chamber is in the elbow outlet tube chamber center line outside.Ore pulp flows to from the elbow entrance like this, and direct " punching " forms whirlpool to spheroid in spherical chamber, flowing out from the elbow outlet, the wearing and tearing of tube wall is dwindled greatly after formation circulation.
