Abstract
The utility model provides a condenser tube plate inner hole polishing and cleaning tool which comprises an electric drill with a drill chuck. A polishing handle is clamped through the drill chuck, a cylindrical polishing head is arranged at the end of the polishing handle, the polishing head is provided with an axial clamping slot which is formed in the top, the bottom and the outer circumferential surface of the polishing head, the outer circumferential surface of the polishing head is wound with abrasive paper, and the tail end of the abrasive paper is crammed into the clamping slot. The condenser tube plate inner hole polishing and cleaning tool has the advantages that he filling speed of the abrasive paper is high, tube holes are cleaned up identically, the polishing speed is several times that of a manual method, inner walls of the tube holes can be quickly polished to be smooth and clean, oil dirt, oxidation layers and dust are not generated, labor efficiency is improved, and the security coefficient is increased.
Description
Technical field
The utility model relates to a kind of condenser tube sheet endoporus polishing cleaning tool.
Background technology
At present, condenser cooling water pipe is normally swollen knot is on the tube sheet of end, pore cleanliness factor is larger to swollen mouthful of quality influence, the unclean meeting of pore causes expand tube insecure, cause recirculated cooling water to leak in condensate water, thereby cause that condensate water hardness exceeds standard, cause the reduction of steam turbine carbonated drink quality, and may cause boiler booster.
Condenser of power plant. the workload of pore cleaning is larger, with 300MW unit condenser, be installed as example, separate unit condenser need be installed more than 23000 cooling water pipe, and two ends tube sheet has more than 46000 pore, each pore need to be cleared up polishing to bright and clean, without grease, oxide layer, dust.Middle 7 dividing plates have more than 161000 pore and need to polish to bright and clean without burr; And 2 condensers of 600MW Steam Turbine are provided with more than 49000 cooling water pipe, need the workload of polishing cleaning larger.Adopted hairbrush to dip in solvent clean greasy dirt, carry out sand papering pore rusty stain again, the speed of the method cleaning pore is slower in the past, the clean level of pore because of artificial origin's difference larger.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of pore cleanliness factor high, the condenser tube sheet endoporus polishing cleaning tool that cleaning efficiency is high.
The utility model is realized by following measures:
A kind of condenser tube sheet endoporus polishing cleaning tool of the present utility model, comprise the electric drill with drill chuck, described drill chuck clamping has polishing handle, the end of described polishing handle is provided with columniform grinding head, on described grinding head, be provided with axial draw-in groove, described draw-in groove is opened on top, bottom and the outer circumference surface of grinding head, on the outer circumference surface of grinding head, is wound with sand paper, and the end of sand paper is filled in draw-in groove.
The length of above-mentioned polishing handle is 30mm, and diameter is 10mm; The width of described draw-in groove is 1.5～2mm, and the draw-in groove degree of depth is 5～6mm.
The cross section of above-mentioned polishing handle is regular hexagon.
The beneficial effects of the utility model are: sand paper filling speed is fast, and pore is cleaned out unanimously, and polishing speed is the several times of manual method, can be rapidly that the polishing of pore inwall is extremely bright and clean, without grease, oxide layer, dust, improved efficiency and safety coefficient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial structurtes schematic diagram.
Wherein: 1 electric drill, 2 drill chucks, 3 polishing handles, 4 grinding heads, 5 draw-in grooves.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to further detailed description:
As shown in Figure 1, 2, a kind of condenser tube sheet endoporus polishing cleaning tool of the present utility model, comprise the electric drill 1 with drill chuck 2, drill chuck 2 clampings have polishing handle 3, the end of polishing handle 3 is provided with columniform grinding head 4, is provided with axial draw-in groove 5 on grinding head 4, and draw-in groove 5 is opened on top, bottom and the outer circumference surface of grinding head 4, on the outer circumference surface of grinding head 4, be wound with sand paper, and the end of sand paper is filled in draw-in groove 5.
Grinding head 4 diameters can cut 2～3mm processing according to the size of pore diameter, so that be wound around sand paper, length should be equal in length with the pore being polished.Polishing handle 3 cross sections are regular hexagon, are convenient to drill chuck 2 clampings of electric drill 1 firmly, the long 30mm of polishing handle 3 handle, and diameter 10mm, is used to facilitate to be clamped on 13mm electric hand drill 1 or pneumatic brill.Wide 1.5～the 2mm of draw-in groove 5, the dark 5～6mm of draw-in groove 5.
During use, will polish handle 3 clampings on electric drill 1, sand paper is cut into sand paper draw-in groove 5 wide, and one, sand paper is stuck in draw-in groove 5, and additional part is wound around a circle along the outer circumference surface of grinding head 4, finally other end is also snapped in draw-in groove 5.Then grinding head 4 is penetrated to pore, start electric drill 1 grinding head 4 High Rotation Speeds, thus pore polishing is extremely bright and clean.Use by job site has improved efficiency effectively, and cleaning speed is the several times of other manual methods, and the pore polishing is all clean bright, can meet the technological requirement of expand tube completely.
The above is only the preferred embodiment of this patent; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the art of this patent principle; can also make some improvement and replacement, these improvement and replacement also should be considered as the protection domain of this patent.
