Description
Technical field
The present invention relates to a kind of mine metallurgical equipment, particularly a kind of concentrator barrel unit manufacture craft.
Background technology
Concentrator is the solid-liquid separating equipment based on gravitational settling effect, is generally the cylindrical shape shallow slot being built up the band cone end by concrete, timber or metal welding fishplate bar as structural material.Its agent structure as shown in Figure 1, primarily of barrel unit a, cylinder bill kept on file unit b, underflow cone c and supporting construction d tetra-major part composition, supported by supporting construction bottom the tube structure that cylinder bill kept on file unit and barrel unit are formed, in barrel unit, upper barrel inwall is provided with the overflow launder of a ring shape, and unit center at the bottom of cylinder arranges underflow cone.
Concentrator can by containing solid be heavily 10% ~ 20% ore pulp by gravitational settling simmer down to solid content be 45% ~ 55% underflow ore pulp, by the effect of rake being installed on microrunning in concentrator (1/3 ~ 1/5r/min), the underflow ore pulp of thickening is drawn off by the underflow opening bottom concentrator, and concentrator top produces more peace and quiet clarified solution (overflow), discharged by the annular chute at top.
Above-mentioned barrel unit is divided into barrel and lower barrel, and upper and lower barrel is connected and composed by vertical adpting flange and bolt by some top cylinder wall flaps 1 or some doffing wall flaps 2 respectively, is is then connected and composed by level connection joint flange and bolt between upper and lower barrel.
The barrel unit of current concentrator is in manufacturing process, first make independently parts, i.e. top cylinder wall flaps, doffing wall flaps, carry out total group again, with form welding equipment bolt plate (adpting flange) in bulk when total group, to reach the assembly precision of latching mechanism form, cannot bolt smoothly when avoiding making in advance total group after adpting flange.But adopt such manufacture craft to there is a problem: because the size of concentrator is larger, height can reach tens even tens meters, and then can produce a large amount of work high above the ground, and location difficulty, greatly reduce workmanship and manufacture efficiency, and there is larger potential safety hazard.
Therefore, a kind of novel concentrator barrel unit preparation method is researched and developed imperative; And through retrieval pertinent literature, do not find the same or analogous technical scheme with the present invention.
Summary of the invention
The technical problem to be solved in the present invention is to provide all high and concentrator barrel unit manufacture craft of safety of a kind of workmanship, efficiency.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of concentrator barrel unit manufacture craft, this barrel unit is divided into circular upper barrel and lower barrel, upper and lower barrel is connected and composed by vertical adpting flange and bolt by some top cylinder wall flaps or some doffing wall flaps respectively, is is then connected and composed by level connection joint flange and bolt between upper and lower barrel; Its innovative point is that described concrete technology step is:
Step S0: the top cylinder wall flaps of barrel unit is set to n, doffing wall flaps is 2n, and n is the integer of >=10;
Step S1: top cylinder wall flaps makes, first makes arc top cylinder wall flaps, in the inner surface erecting and welding overflow groove segmentation of top cylinder wall flaps with barrel center line for benchmark is sleeping on tangent moulding bed;
Step S2: the setting of positioning datum, again the top cylinder wall flaps center line after welding is revised, and lower end is struck loading and is developed and printed to identify revised center line thereon, simultaneously the upwards positioning datum pre-installed as upper and lower barrel assembly zygonema of 500mm place sign level in top cylinder wall flaps lower edge, sends into the upright pre-splicing making district of upper and lower barrel;
Step S3: doffing wall flaps makes, and is pressed into arc after the blanking of doffing wall flaps by equipment, and center line draw the correction of upper and lower barrel sheet before being pressed into arc before, then send into the upright pre-splicing making district of upper and lower barrel;
Step S4: upright pre-splicing making district is equipped with pre-splicing frock at upper and lower barrel, this pre-splicing frock comprises some upper barrel bracing frames and lower barrel bracing frame, and described each upper barrel bracing frame and lower barrel bracing frame interval are arranged and the overall distribution in circular arc; One horizontally disposed upper barrel location-plate, on this, barrel location-plate is a circular arc plate body extended along concentrator barrel circumferencial direction, be welded and fixed outside the upper end of its arc shaped inside face and each upper barrel bracing frame, and then each upper barrel bracing frame is connected to form an entirety; One horizontally disposed lower barrel top positioning plate, this lower barrel top positioning plate is similarly a circular arc plate body extended along concentrator barrel circumferencial direction, its arc shaped inside face respectively with the middle-end of each upper barrel bracing frame outside and lower barrel bracing frame upper end outside be welded and fixed, and then each upper and lower barrel bracing frame is connected to form an entirety; Some clearance locating plates for controlling upper and lower barrel gap, described clearance locating plate arranges by a vertically disposed location-plate body front end convex tendon stretched out forward and forms, the upper surface of lower barrel is close in the lower surface of this convex tendon, location-plate body lower part is close to the back side of lower barrel, and location-plate body and the spot welding of lower barrel medial surface are fixed; Some horizontal location plates for controlling upper and lower barrel level connection joint flange position, described horizontal location plate is a L shaped plate body, and the lower extreme point solid welding of this L shaped plate body fixes on outside the upper end of lower barrel
