In the prior art, it is the liner line with rubber in pipe, but in a linear relationship between line with rubber wearability and the flow velocity of fluid is in Geometric linear relationship reduces.Original tapered pipeline inner liner rubber is by the eddy flow and slurry flow rate (7m/ generated in serum recycle pump operation S or so) be affected, abrasion spillage is frequently occurred in operation.After virgin pulp liquid pump inlet tapered pipeline puts into operation certainly, Longest run time 91 days, abrasion spillage occurred within the shortest time 25 days.Slurry circulating pump outlet conduit relative operation time compared with It is long, the longest run time 150 days or so.Occur abrasion spillage position all occurring at pipeline smallest end diameter at, so be badly in need of Circulating pump imports and exports reducing pipe to solve the above-mentioned problem.
Utility model content
In view of the deficienciess of the prior art, the utility model aim is to provide circulating pump inlet and outlet reducing pipe, with solution Certainly the problems mentioned above in the background art, the utility model is easy to use, long service life, alleviates labor intensity, improves Stability, convenient for protecting inner tube.
To achieve the goals above, the utility model is achieved through the following technical solutions: circulating pump inlet and outlet are different Diameter pipeline, including ring flange one, straight tube one, conical pipe, straight tube two, ring flange two, protective plate, mounting blocks, bolt, sliding block, subtract Shake spring and sliding groove, the ring flange one are mounted on one left side of straight tube, and the straight tube one is welded on conical pipe left end On face, the straight tube two is welded on conical pipe right side, and the ring flange two is assemblied on two right side of straight tube, the protection Plate is assemblied in conical pipe annular side upper end, and the protective plate is connected by sliding block with mounting blocks, and the mounting blocks are welded on On one right side of ring flange, the bolt is arranged in mounting blocks right side upper end, and the sliding block is assemblied in sliding groove, the cunning Block fits with damping spring upper end, and the damping spring is fixed in sliding groove on lower end surface, and the sliding groove is provided with peace It fills on block upper surface.
In one embodiment, the mounting blocks right side offers open slot, and the open slot is connected with sliding groove.
In one embodiment, the protective plate is equipped with two groups, and protective plate described in two groups is symmetrically assemblied in conical pipe annular side Face upper end and annular side lower end.
In one embodiment, the mounting blocks, bolt, sliding block, damping spring and sliding groove are equipped with four groups, four groups of institutes Mounting blocks, bolt, sliding block, damping spring and sliding groove is stated symmetrically to be assemblied on ring flange one and ring flange two.
In one embodiment, silicon carbide inner tube is lined on the straight tube one, conical pipe and straight tube two.
The utility model has the beneficial effects that the circulating pump of the utility model imports and exports reducing pipe, because the utility model adds Added ring flange one, straight tube one, conical pipe, straight tube two, ring flange two, protective plate, mounting blocks, bolt, sliding block, damping spring with And sliding groove, the design achieves long service life, alleviate the labor intensity of repair and maintenance personnel, improve slurry circulating pump Running stability solves existing pipeline and is prone to wear spillage convenient for the function of protecting inner tube, and service life is short, warp The problem of often operating personnel being needed to repair.
Because the utility model is added to open slot, which drives protective plate sliding convenient for sliding block, because the utility model adds Silicon carbide inner tube is added, which improves service life, the utility model is easy to use, makes convenient for improving pipeline corrosion resistance It is long with the service life, labor intensity is alleviated, stability is improved, convenient for protecting inner tube.
