Abstract
The utility model relates to a rust removing and scale removing device for the inner wall of a large and medium-diameter metal pipe, which comprises a plastic pipe, sand grains, an explosion wire, a detonator, a bracket and the like. The detonating cord and the detonator form the power source of the device, and when the power is released, the detonating cord and the detonator can push sand grains in the plastic pipe to disperse at high speed and impact rust and scale on the metal pipe wall. The utility model is suitable for a rust cleaning, scale removal of the metal pipe inner wall of big, well pipe diameter, work efficiency is high, installation, convenient operation, low cost.
Description
The utility model relates to a kind of inner wall of metal tube rust cleaning, apparatus for eliminating sludge of big or middle caliber, a kind of inner wall of metal tube of self-powered source rust cleaning specifically, apparatus for eliminating sludge.
In each place of daily life and industrial production activity, the use of metallic conduit is very extensive.Most of pipelines in use, inwall can get rusty and adhere to dirt, metal tube is being deposited process, also can produce corrosion in the tube wall, these rust, dirt and inner wall of metal tube produce stronger adhesion.Usually the mode one of removing rust, dirt is by manually knocking or root out, and will become rusty, dirt separates with tube wall, and this mode labour intensity is big, efficient is low, and often not thorough to the rust of pipeline, dirty removing, also can injure the metal surface.The 2nd, adopt chemical method to remove rust, dirt, generally be chemical reaction to take place with rust, dirt in acid solution and the tube wall, make dirt loose.This mode is usually used in more small-bore metal tube, and for the metal tube of big or middle caliber, it is just very complicated to implement its technology of chemical method, execution conditions require high, in rust cleaning, dirty process, have " three wastes " and produce, cause environmental pollution, thereby do not used in large quantities.In practical work, often more visible pipelines owing to can not thoroughly clearing up inwall rust, dirty giving it up, cause very big waste.
Task of the present utility model provides a kind of inner-walls of duct rust cleaning, apparatus for eliminating sludge, and this device leans on the power source that self disposes, and can remove rust, the dirt of inner wall of metal tube easily and quickly, and easy to operate, with low cost.
In order to solve above-mentioned task, the technical scheme that the utility model is taked is, two ends are had the sand grains 4 of packing in the plastic tube 1 of end socket 5 shutoff, and penetrate power source 3 at the center, several bearing supports 2 are set on the external diameter of plastic tube 1, the two ends of primacord 3 are fixed by end socket 5, and an end wherein is connected with the outer detonator 6 of plastic tube.Primacord and detonator have constituted the power source of device, can release energy as quick as thought when needed.
The utility model is owing to disposed primacord and the power source of detonator composition in device, when power source is done the time spent, the sand grains that its energy promotes in plastic tube distributes at a high speed, rust, dirt on the bump metal pipe-wall, it is separated with tube wall fast, remove rust, dirt that inside pipe wall adheres to up hill and dale.High efficiency, and easy for installation, simple to operate, with low cost.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is inner wall of metal tube rust cleaning, the apparatus for eliminating sludge schematic diagram of large and medium-sized caliber of the present utility model.
With reference to Fig. 1.The caliber of the metal tube 7 of rust cleaning, scale removal is made plastic tube 1 as required, and its external diameter approximately is 1/4 of a metal tube caliber, cover one retable material bearing support 2 on the external diameter, and bearing support 2 contacts with inner wall of metal tube, and by equidistantly placing.Be full of sand grains 4 in the plastic tube 1 and penetrate a power source 3 in the centre, with Plastic cap 5 with shutoff of the plastics mouth of pipe and fixing primacord 3.End at primacord connects the electric cap 6 that protective sleeve is housed.
The above-mentioned device that assembles is pushed in the metal tube, lead on the electric cap is inserted initiator, connect main firing electric cap and primacord, the impact energy that produce this moment makes in the plastic tube sand grains break through plastic tube at a high speed and distributes everywhere, strong bump inner wall of metal tube is thoroughly removed the rust on the inside pipe wall, dirt.
In implementation process, also can use non-electrical engineering detonator, can satisfy the requirement of device equally.
Claims (1)
