Background

2021.08.31 the grant bulletins have the bulletin number: the Chinese patent of CN 214078035U discloses an automatic ash removing device for a steel wire rope. The cleaning device comprises a control system, a cleaning assembly and a blowing assembly, wherein the control system comprises a control host, a cleaning control valve and a blowing control valve, and the control host is electrically connected with the cleaning control valve and the blowing control valve respectively; the cleaning assembly comprises a water supply pipeline and a cleaning ring, wherein the cleaning ring is a hollow annular cavity, an inner cavity of the cleaning ring is communicated with the water supply pipeline, the blowing assembly comprises a compressed air pipeline and a blowing ring, the blowing ring is a hollow annular cavity, and an inner cavity of the blowing ring is communicated with the compressed air pipeline; the system constructs a cleaning system comprising two links of cleaning and drying.

It is known that lubricating grease is coated on the steel wire rope, when dust is removed by adopting the mode of cleaning before drying, ash-cleaning water inevitably drops to the ground below the steel wire rope to pollute the site, the steel wire rope is cleaned by water, and once the water attached to the steel wire rope cannot be dried sufficiently, the steel wire rope is inevitably corroded, so that the service life of the steel wire rope is reduced.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide the vacuum ash removal device for the elevator steel wire rope, wherein coal ash is not escaped and the steel wire rope is not affected with damp.

In order to solve the technical problem, this vacuum ash removal device for lifting machine wire rope includes combination vacuum cover, vacuum wash tank and vacuum pump, the combination vacuum cover includes left shell and right shell, both include upper semi-ring shrouding, lower semi-ring shrouding and semicircle curb plate, the semicircle curb plate is gone up, the lower edge is connected respectively on the outer edge of upper semi-ring shrouding and the outer edge of lower semi-ring shrouding, vertical otic placode outwards extends at two semicircle curb plate both ends, and open on the vertical otic placode has the through-hole, left and right shell lock is on the wire rope both sides of waiting the deashing, the through-hole on the vertical otic placode of its both sides is relative, and wear to have fastening bolt in the through-hole that is relative, and still communicate on left shell or the right shell has the dust absorption pipe, it has the washing liquid to annotate in the vacuum wash tank, the dust absorption pipe other end extends to the vacuum wash tank in, and stretches into below the washing liquid level, still be equipped with horizontal metal mesh in the vacuum wash tank, this horizontal metal mesh is located between washing liquid level and the lower port of vacuum pump, and the distance between horizontal metal mesh and the washing liquid level is 1 cm, and the top of washing liquid level is equipped with the drain pipe, the drain pipe is equipped with the drain pipe top, this drain pipe is equipped with the drain pipe, the drain pipe is still connected with the top of drain pipe.

The inner edges of the upper semi-ring sealing plates and the lower semi-ring sealing plates of the left shell and the right shell are mutually spliced to form a central hole, and the central hole and the circumferential seam of the steel wire rope to be ash removed in the central hole are air suction circumferential seams.

When the combined vacuum cover is used, the left shell and the right shell of the combined vacuum cover are fixed on two sides of the steel wire rope to be subjected to ash removal, so that the left shell and the right shell encircle the steel wire rope to be subjected to ash removal, but are not contacted with the steel wire rope to be subjected to ash removal. And then injecting the water washing liquid into the vacuum water washing tank to enable the liquid level of the water washing liquid to reach or exceed the horizontal metal net, and keeping a certain gas space at the top of the vacuum water washing tank. Then, the liquid supplementing valve is closed, the vacuum pump is started, and vacuum dust collection is performed.

When the vacuum pump operates, the air space at the upper part of the vacuum washing tank is sucked into a negative pressure area, the negative pressure area sucks air from the combined vacuum hood through the dust suction pipe, the outside air can only enter through the suction circular seam between the combined vacuum hood and the steel wire rope to be subjected to dust removal, the sucked air forms air flow to drive the floating dust on the steel wire rope to be subjected to dust removal, the floating dust is brought into the vacuum washing tank, the floating dust enters into the washing liquid from the bottom and is crushed into micro bubbles after encountering a horizontal metal net, the floating dust carried in the air enters into the washing liquid, and clean air is sucked out through the vacuum pump and then is emptied.

The design is that the coal ash is not escaped, the steel wire rope is not affected with damp, and the ash cleaning effect is good.

As optimization, a sealing gasket is arranged between the left shell and the right shell. So designed, there is no seam between the left shell and the right shell, and the vacuum ash absorbing effect is good.

As optimization, the side wall of the vacuum rinsing tank is also provided with a strip-shaped window, and transparent glass is sealed on the strip-shaped window. By the design, the water washing liquid amount in the vacuum water washing tank, the dust content in the water washing liquid and the sedimentation condition are convenient to observe, when the water washing liquid contains more dust, the vacuum pump can be stopped, the liquid supplementing valve is opened, and then the sewage discharging valve is opened to discharge sewage. When the dust at the bottom of the vacuum water washing tank is more settled, the water is injected into the vacuum water washing tank through the water supplementing valve for cleaning, and then the sewage is discharged again, so the process is repeated until the vacuum water washing tank is clean and has no settlement, and then the water washing liquid is injected again.

The vacuum ash removal device for the elevator steel wire rope is scientific in design, convenient to use, free from coal ash escaping and damp, and suitable for the elevator steel wire rope of the coal mine.
