Abstract
The invention discloses a kind of ceramic-lined wear pump pipe bend, comprise elbow main body, described elbow main body inner wall covers and is pasted with some lined ceramics sheets, described lined ceramics sheet is in the arc corresponding with elbow main body inner wall cambered surface, lined ceramics sheet thickness on elbow main body inner wall outer arced surface is greater than the lined ceramics sheet thickness on intrados, and described each lined ceramics sheet thickness even transition on the inside cambered surface direction of outer arced surface.Ceramic-lined wear pump pipe bend long service life of the present invention; Make more convenient; The shape compatible degree of lined ceramics sheet and elbow main body inner wall is high, difficult drop-off; And because lined ceramics sheet is smaller, can not be all cracked because of greater impact easily, there is crack damage individually even if having, also can not affect the use of other lined ceramics sheets.
Description
Technical field
The present invention relates to concrete mixer equipment technical field, be specifically related to a kind of ceramic-lined wear pump pipe bend.
Background technique
Now, on market, pump truck manufacturer generally adopts high manganese steel to cast the elbow of pump line, this product generally uses three, four months, and i.e. breakage cannot use, reason is that concrete produces huge friction in pump truck pipeline high speed high-pressure flow, by the outer arc place heavy wear of pump line elbow interior wall, thus elbow is caused to use.
Now commercially there is a kind of abrasion-proof ceramic lining pump line elbow; its feature sticks wear-resistant ceramic uniformly at inwall; although wear-resistant ceramic serves certain protection to pump line elbow interior wall; but due to the wear-resistant ceramic of the same thickness that whole elbow adopts; like this; the time marquis of the outer arc place breakage of inwall, the wear-resistant ceramic at the inner arc place of the inwall of product is almost damaged little, causes the waste of material.
Summary of the invention
The object of the invention is to provide length of a kind of life-span, material saving, ceramic-lined wear pump pipe bend that inwall resistance is little for the problem of above-mentioned prior art.
The technical solution used in the present invention is: a kind of ceramic-lined wear pump pipe bend, comprise elbow main body, described elbow main body inner wall covers and is pasted with some lined ceramics sheets, described lined ceramics sheet is in the arc corresponding with elbow main body inner wall cambered surface, lined ceramics sheet thickness on elbow main body inner wall outer arced surface is greater than the lined ceramics sheet thickness on intrados, and described each lined ceramics sheet thickness even transition on the inside cambered surface direction of outer arced surface.By arranging lined ceramics sheet in elbow main body inner wall, avoiding concrete grout and directly to wear and tear tube wall; The lined ceramics sheet thickness on intrados is greater than due to the lined ceramics sheet thickness on elbow main body inner wall outer arced surface, the life-span of the lined ceramics sheet in the life-span of the lined ceramics sheet on the outer arced surface making wearing and tearing more serious and Inner cambered surface is suitable, avoids outer arced surface premature abrasion and scraps and the waste of material that causes.
Described elbow body interface place inwall is pasted with thickness and connects ceramic plate uniformly, connects ceramic plate in the arc corresponding with elbow main body, and the thickness connecting ceramic plate is less than the thickness of lined ceramics sheet.Adopt the technical program that the common pump line of elbow and other can be facilitated to be connected.
Between described connection ceramic plate and lined ceramics sheet elbow main body inwall on be pasted with transition ceramic plate, the inner end edge of transition ceramic plate flushes with the edge of adjacent lined ceramics sheet, the edge of the connection ceramic plate that the outer end edges of transition ceramic plate is adjacent flushes, and the thickness of transition ceramic plate is from even transition the inside extreme direction in outer end.Arranging transition ceramic plate, that concrete grout can be made to flow in pump line is more smooth and easy, can reduce the concentrated wear of transition position simultaneously.
The invention has the beneficial effects as follows: ceramic-lined wear pump pipe bend of the present invention, by arranging lined ceramics sheet in elbow main body inner wall, avoids concrete grout and directly to wear and tear tube wall; The lined ceramics sheet thickness on intrados is greater than due to the lined ceramics sheet thickness on elbow main body inner wall outer arced surface, the life-span of the lined ceramics sheet in the life-span of the lined ceramics sheet on the outer arced surface making wearing and tearing more serious and Inner cambered surface is suitable, long service life, and the waste of material that the lined ceramics sheet premature abrasion avoiding outer arced surface is scrapped and caused; The mode of pasting some ceramic plates is adopted to make ceramic plate liner more convenient when making, high with the shape compatible degree of elbow main body inner wall, and difficult drop-off, and because lined ceramics sheet is smaller, can not be all cracked because of greater impact easily, there is crack damage individually even if having, also can not affect the use of other lined ceramics sheets; Easily repair afterwards in the fragmentation of individual ceramic sheet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is elbow cross sectional representation;
Shown in figure: 1, elbow main body, 2, lined ceramics sheet, 3, connect ceramic plate, 4, transition ceramic plate.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
The ceramic-lined wear pump pipe bend of one as depicted in figs. 1 and 2, comprise elbow main body 1, described elbow main body 1 inwall covers and is pasted with some lined ceramics sheets 2, described lined ceramics sheet 2 is in the arc corresponding with elbow main body inner wall cambered surface, lined ceramics sheet 3 thickness on elbow main body 1 inwall outer arced surface is greater than lined ceramics sheet 3 thickness on intrados, and described each lined ceramics sheet 3 thickness even transition on the inside cambered surface direction of outer arced surface; Elbow main body 1 jointing inwall is pasted with thickness and connects ceramic plate 3 uniformly, connects ceramic plate 3 in the arc corresponding with elbow main body 1, and the thickness connecting ceramic plate 3 is less than the thickness of lined ceramics sheet 2; Between described connection ceramic plate 3 and lined ceramics sheet 2 elbow main body 1 inwall on be pasted with transition ceramic plate 4, the edge of the lined ceramics sheet 2 that the inner end edge of transition ceramic plate 4 is adjacent flushes, the outer end edges of transition ceramic plate 4 flushes with the edge of adjacent connection ceramic plate 3, and the thickness of transition ceramic plate 4 is from even transition the inside extreme direction in outer end.
Although be described the specific embodiment of the present invention by reference to the accompanying drawings above-mentioned, not limiting the scope of the invention, such as base plate 1 can also arrange two or more sets support plates and install to facilitate several contact base simultaneously.One of ordinary skill in the art should be understood that on the basis of technological scheme of the present invention, and those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
