The utility model discloses it is easy and simple to handle, long service life, economic benefits is high, is favorable to the serialization safety in production, is applicable to the serialization safety in production of trades such as metallurgy, electric power, mine, chemical industry, cement.
Description
Technical field
The utility model belongs to conveying pipe technical field, particularly the large-scale wear-resisting conveying pipe elbow of one.
Background technique
Through investigation, domestic and international large-scale conveying pipe, elbow, be widely used in the industries such as metallurgy, electric power, mine, chemical industry, cement, port and pier, annual consumption a large amount of band large-scale metal pipeline, elbow.And these band large-scale metal pipelines, elbow interior wall resistance to wear process substantially do not pass a test, substantially all belong to Passive design.Have at high-abrasive materials such as elbow interior wall position easy to wear coating silicon carbides, complex process, expensive.The ceramic plate pasted as the armor had, during power-plant operation, is engraved in during high temperature and high speed coal dust and impacts elbow bending part, this place's ceramic plate is often departed from, and therefore, usually there is damaged gap in channel bend, coal dust is erupted by these gaps, very easily blasts, very dangerous! And this technique is very complicated, only 1 year life-span.Only transporting coal dust elbow so that power station, Inner Mongol is large-scale: in order to ensure power station normal power generation safe operation, a same Large-scaled Elbow must be laid in each elbow.Under normal operating conditions; less than within 1 year, stopping production, to shut down; change new elbow and could continue pulverized coal conveying generating; old elbow must be transported to producer and process: that first the ceramic plate on its inwall is extremely required great effort by artificial means removes; paste new ceramic sheet again, and could apply after kiln roasting, cooling must be transported to.Considerably increase the expenses such as lifting cost, porterage, installation fee.If elbow occurs that ceramic plate departs from, there is damaged gap, find coal dust ejection, must to stop production the elbow more renewed by hard stop! Often bring great inconvenience, hidden danger and loss to production.
Model utility content
The purpose of this utility model is to overcome deficiency of the prior art, and provide a kind of easy and simple to handle, long service life, high financial profit, is conducive to the large-scale wear-resisting conveying pipe elbow of continization safety in production.
The purpose of this utility model is achieved through the following technical solutions.
Large-scale wear-resisting conveying pipe elbow of the present utility model, be made up of elbow body, outside described elbow body, crooked position is provided with air-flow path, a through hole from top to bottom, described through hole arranged outside has the dunnage be flexibly connected with described elbow body, and described dunnage internal surface is provided with wear-resisting projection.
Described wear-resisting convex shape is streamline or circular arc.
Described wear-resisting projection is made up of high-abrasive material, described high-abrasive material by Hard Alloy Steel, silicon carbide or pottery wherein one form.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
(1) the utility model is provided with streamlined wear-resisting projection at dunnage internal surface, and when elbow body through-holes is closed by dunnage, wear-resisting projection is placed in channel bend inside, is conducive to fluid particle and turns round in channel bend commutation.
(2) in the utility model, wear-resisting projection is arranged at dunnage internal surface, as long as open dunnage, just can clamp abrasion resistant convex fast and rise, need not stop production, shut down, very convenient, greatly saves time, substantially increases manufacturing efficiency and economic benefit.
(3) on the upside of the utility model through hole, crooked position is provided with an air-flow path; introduce a strong air-flow; formed in elbow body upper part region easy to wear with air cushion; fluid particle is forced to turn; make that entrained particle is more difficult impacts elbow body upper part region easy to wear; make it more effectively be protected, greatly to extend the working life of large-scale conveying pipe elbow, improve productivity effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is that in the utility model, entrained particle flows to schematic diagram.
Reference character: 1 wear-resisting protruding 4 air-flow path 5 regions easy to wear of through hole 2 dunnage 3
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1 to Figure 3, large-scale wear-resisting conveying pipe elbow of the present utility model, be made up of elbow body, ceramic plate can be covered with inside described elbow body, outside described elbow body, crooked position is provided with through hole 1 from top to bottom, described through hole 1 arranged outside has the dunnage 2 be flexibly connected with elbow body, and described dunnage 2 shape suits mutually with elbow body.Described dunnage 2 internal surface is provided with wear-resisting protruding 3, the described wear-resisting shape of protruding 3 can be set to streamline or circular arc etc., size can design according to pore size, described wear-resisting protruding 3 are made up of high-abrasive material, described high-abrasive material can by the materials such as Hard Alloy Steel, silicon carbide or pottery wherein one form, be forced to after fluid particle runs into wear-resisting protruding 3 turn commutation.Described wear-resisting protruding 3 can clamp fixing with dunnage 2, when changing wear-resisting protruding 3 in process of production, and only need open that dunnage 2 more renews wear-resisting protruding 3, need not stop production shutdown.According to hydrodynamic characteristic, on the upside of the through hole 1 of described elbow body, crooked position arranges one air-flow path 4, to introduce a powerful air-flow, forms an air cushion, to force fluid particle to be turned in region 5 easy to wear.
The utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; not restrictive; those of ordinary skill in the art are under the utility model enlightenment; do not departing under the ambit that the utility model aim and claim protect; also can make the concrete conversion of a lot of form, these all belong within protection domain of the present utility model.
