Detailed description of the invention
Embodiment 1
Below by way of detailed description of the invention and in conjunction with accompanying drawing, technical scheme is illustrated.
The cooling water recirculation system of a kind of oil extraction as shown in Figure 1, technical process is summarized as follows:
Oil extraction water circulation cooling, in order that realize solvent condensation to realize the circulating leaching of solvent, the cold water of circulating water pool 2 purifies conveying by circulating pump A conveying by eddy flow scummer 7 and is supplied to heat exchanger package 5, plate type heat exchanger 51 adopts two respectively to solvent evapo-separated machine, a large amount of solvent vapo(u)rs of the first long-tube evaporator condense, row are to heat exchanger 52 multiple stage parallel connection respectively infuser, second long-tube evaporator, strippers etc. realize steam condensation, liquefaction solvent concentrates inflow solvent diversion box 6 to carry out water separation, divide aqueous solvent to carry out reflux cycle again to realize leaching circulation；The hot water of centralized water return pipe 4 leaves condenser to be continued to deliver into cooling tower 1 and realizes radiating and cooling, and cold water falls into circulating water pool and constantly circulated the heat radiation of solvent condensation.Heat exchanger package as figure house steward 4,8 pipe-connecting mode favourable condenser flow distribution rationally uniform.
The reliable and stable work of circulating pump A is the key element of cooling system normal operation, in the design, mainly the shafting structure of pump is combined and carries out innovative design, it is simple to the quick demolition and maintenance of pump；Coordinate in motion thread assembling at actual axle with hole, in order to be able to realize big bearing function demand, thread spindle is all relatively big with the scantling of the similar nut member matched, and it is often all also very easily convenient to screw in when assembling, and in use can realize the constantly locking automatically of bearing capacity, thus very reliable, but when dismantling, assembling is very tight often, dismantle also very difficult, if simple easy removal can be realized under these conditions, it appears particularly important, also it is the main points of innovative design.
The axle system of circulating pump is taked conventional typical structure as shown in Figure 2:
Patent formula of the present invention is applied to shaft components screw-threaded coupling field, pump shaft 14 and impeller of pump 11, belt pulley 15 all adopts Screw assembly, thread rotary orientation is with work and is carried as energy auto lock direction, need to utilize during detachable maintaining the copper-lead composite pad 12 of innovative design, clip assembly 16, pass through operation readiness, can simply eliminate the similar nut member pressure to screw shaft shoulder end face, at this moment nut and screw part are in unloading vacant state, take apart and become equally simple and convenient with Screw assembly, largely effective for solving Screw assembly continuous not easily detachable situation of auto lock under load effect, particularly mammoth pump shaft components screw-threaded coupling field, such function is particularly important.Additionally, copper-lead composite pad, clip pad can play good Stress decomposition effect, effectively strengthen the bearing capacity of structure.
The structure of copper-lead composite pad 12 is as shown in Figure 3:
Make circular copper packing to carry out punch process and be shaped to copper packing 21 and fin, then at copper packing both sides compound fusible lead alloy packing ring 22, as shown in Figure 3, it is easy to copper packing is heated.
Copper-lead Composition spacer 12 is compressed by the similar nut of impeller of pump 11 by being connected with male thread, and impeller of pump 11 and axle form screw thread and be rigidly connected.When impeller of pump 11 needs dismounting but is very difficult, adopt oxy arc that the copper packing 21 in the middle of copper-lead Composition spacer 12 is carried out oxy arc heat treated, owing to the conductivity of heat of copper is fabulous, and the fusing point of metal is relatively low, after heating, metal is heated melting, the compression tensile force of impeller of pump 11 and shaft shoulder step is completely eliminated, and makes impeller of pump 11 be in vacant state completely and is especially susceptible to dismounting.
The structure chart of clip assembly 16 is as shown in Figure 4:
As shown in Figure 5, clip 31 cross section is wedge shape, formed opening structure by two semicircular ring card hoop bodies, the structure of flexible collar pad 33 is as shown in Figure 6, clip pad both sides are planar structure, it is easy to coordinate with shaft shoulder plane, clip uses bolt 35 through the hole on clip ear 32, it is assemblied on clip pad to be integrally forming, it is inserted in pump shaft 14 and screws in the pulley 15 of similar nut again, rationally all locking again, makes clip, the clip pad pulley 15 with similar nut constitute with pump shaft 14 and is rigidly connected, meet instructions for use.When the pulley 15 of similar nut needs dismounting but is very difficult, with spanner, bolt 35 is pulled down, because two semicircular ring card hoop bodies are quick it is that the inner surface of wedge shape and clip ear 32 end is provided with chamfering to opening structure, clip body section, can connect to close up from two clip ears 32 with the flat instrument in one end and easily pry open, clip easy removal is got off, clip pad returns to relaxed state, make the tensile force after the locking of pulley 15 and shaft shoulder end face be completely eliminated, make the pulley 15 similar nut of energy be in vacant state completely and be especially susceptible to dismounting.
Above are only the concrete guiding embodiment of the present invention, but the design concept of the present invention is not limited thereto, all changes utilizing this design that the present invention carries out unsubstantiality, the behavior invading protection scope of the present invention all should be belonged to.
