Description
Technical field
The present invention relates to a kind of atomization mechanism, particularly relate to a kind of development machine wet type inner sprayer unit.
Background technology
The coal petrography because development machine declines continuously makes the work plane dust from flying, and this not only influences the healthy of workman, also is related to safety in production.Depend merely on ventilation and air-borne dust content can not be dropped in the critical field, therefore must adopt necessary dust suppression.
Usually the used atomizing dedusting method of development machine is to have the water high diffusion of certain pressure with the nozzle handle, makes its atomizing, makes dust be attached to vaporific water particle surface precipitation and gets off, to reach the dirt effect of going out.This dirt mode of going out is divided into external spraying and internal spraying.
External spraying is simple in structure, reliable operation, and long service life, because nozzle is far away from dust source, dust spreads apart easily, dust-laying effect is relatively poor.
Internal spraying is to install nozzle on cutterhead, sprays facing to dust source.The characteristics of internal spraying are that the nozzle distance pick is near, and the dirt that goes out is effective, water consumption is little, water down gas, cool off pick and put out the effect of spark better.Nozzle stops up easily and damages, supply channel complexity, movable connection place sealing difficulty.
Summary of the invention
It is simple that technical problem to be solved by this invention provides a kind of supply channel, movable connection place good sealing effect, seal durability height, the development machine wet type inner sprayer unit that spray effect is good.
In order to solve the problems of the technologies described above, development machine wet type inner sprayer unit provided by the invention, water inlet is sleeved on the cutter head shaft and communicates with water channel on the described cutter head shaft and be fixedly mounted on the outer cylinder body, described outer cylinder body is provided with the water inlet pipe that communicates with described water inlet cover, sealing shroud is fixedly mounted on the cutter head shaft and with described water inlet cover and seals, be provided with bearing and bearing (ball) cover between described cutter head shaft and the described water inlet cover, described water inlet is overlapped by being formed with left oil pocket between a side of the outer end of described cutter head shaft and the described outer cylinder body, be formed with right oil pocket between described water inlet cover and the described bearing, be drilled with first through hole that described left oil pocket and right oil pocket are communicated in described water inlet cover bottom.
Be drilled with second through hole at described water inlet cover and bearing cover top, described second through hole makes described left oil pocket and right oil pocket communicate with the right chamber of cantilever segment, and the below that communicates, the right chamber that described outer cylinder body is in described cantilever segment is provided with the plug that leaks.
Adopt lattice to enclose and seal with O ring between described water inlet cover and sealing shroud.
Adopt the development machine wet type inner sprayer unit of technique scheme, water is introduced by water inlet pipe, in water inlet cover, sealing shroud enter the annular seal space of the body of the cutting head and cutter head shaft composition.Press water through cavity by go out the atomized water dirt that goes out by the nozzle ejection on the cutterhead.In order to make movable connection place good sealing effect, inner sprayer unit is provided with two left oil pockets that communicate and right oil pocket, and purpose is that lubricated simultaneously lattice enclose and bearing, and the oil filling position is higher than lattice and encloses and get final product; Second through hole is bored on water inlet cover top, communicates with open-work that bearing cover bores, if seal damages, the water that is leaked can flow into the right chamber of cantilever segment, can learn that by the plug that leaks that the outer cylinder body lower end is set inner sprayer unit leaks, and simultaneously the water of being revealed is discharged.
In sum, the present invention is that a kind of supply channel is simple, movable connection place good sealing effect, seal durability height, the development machine wet type inner sprayer unit that spray effect is good.
Description of drawings
Fig. 1 is the structural representation front view of development machine wet type inner sprayer unit;
Fig. 2 is the structural representation vertical view of development machine wet type inner sprayer unit.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1 and Fig. 2, water inlet cover 4 is sleeved on the cutter head shaft 1 and communicates with water channel on the cutter head shaft 1 and be fixedly mounted on outer cylinder body 2 inwalls by stopping means 14, outer cylinder body 2 is provided with and cover 4 water inlet pipes that communicate 6 of intaking, sealing shroud 3 is fixedly mounted on the cutter head shaft 1 by stop screw 13 and adopts lattice to enclose 7 and 5 sealings of O shape circle with water inlet cover 4, be provided with bearing 9 and oil sealing 8 between cutter head shaft 1 and the water inlet cover 4, bearing (ball) cover 11 is connected with water inlet cover 4 by attachment bolt 10, water inlet cover 4 is by being formed with left oil pocket 19 between side of the outer end of cutter head shaft 1 and the outer cylinder body 2, be formed with right oil pocket 16 between water inlet cover 4 and the bearing 9, be drilled with first through hole 18 that left oil pocket 19 and right oil pocket 16 are communicated in water inlet cover 4 bottoms, be drilled with second through hole 15 at water inlet cover 4 and bearing cover 11 tops, second through hole 15 makes left oil pocket 19 and right oil pocket 16 communicate with the right chamber 17 of cantilever segment, the right chamber 17 of cantilever segment fills in 12 by being provided with to leak below described outer cylinder body 2, and then the water of revealing is got rid of.As depicted in figs. 1 and 2, water is introduced by joint and water inlet pipe 6, in water inlet cover 4, sealing shroud 3 enter the annular seal space of the body of the cutting head and cutter head shaft 1 composition.Press water goes out the atomized water dirt that goes out through cavity by the nozzle ejection on the cutterhead.
Bore first through hole 18 in water inlet cover 4 bottoms, left oil pocket 19 and right oil pocket 16 are communicated, finish lattice and enclose 7 and bearing 9 lubricated, the lubrication oil position is annotated and is enclosed 7 tops to lattice and get final product.Be drilled with second through hole 15 at water inlet cover 4 and bearing cover 11 tops, left oil pocket 19, right oil pocket 16 are communicated with the right chamber 17 of cantilever segment.When the seal damage is leaked, can flow into the right chamber 17 of cantilever segments by this second through hole 15, discharge via the plug 12 that leaks of outer cylinder body 2 belows.
3 of water inlet cover 4 and sealing shrouds enclose 7 sealings with lattice, are movable sealing, and water inlet cover 4 links with outer cylinder body 2, is circumferentially rotated by stopping means 14 restrictions, and by 9 supportings of a bearing, makes its alignment good, improve lattice and enclose 7 durability; Sealing shroud 3 links by stop screw 13 and cutter head shaft 1, rotates in a circumferential direction with cutterhead.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
