Abstract

The utility model provides a split type lubricating oil filling nozzle which comprises an emission head arranged in an oil spraying port. The emission head is provided with one or more channels. Lubricant and conveying airflow flow along the channels. Each channel is in a diminishing structure and provided with a wide entrance region and a narrow-sized exit. Each wide entrance region enables the lubricant and the conveying airflow to be high-efficiently gathered. Each narrow-sized exit enables the lubricant to be conveyed to a needle-shaped end portion at the position of the emission head so as to form liquid drops. Meanwhile, the conveyed airflow sprays the liquid drops to a target through a string of liquid drops with constant size from the needle-shaped end portion at the position of the emission head. The split type lubricating oil filling nozzle has the advantages of being capable of accurately controlling the size of lubricating oil drops, enabling the size of the oil drops to be uniform, capable of removing oil mist in the sprayed lubricating oil, and capable of reducing pollution to environment.

Description

A kind of split type oil filling nozzle

Technical field

The utility model relates to a kind of jet atomization device, specifically a kind of split type oil filling nozzle.

Background technique

In process industry, usually need to the particular elements of equipment be lubricated, such as the weaving machine in the textile industry or the pile hammer in the machinery industry etc.The lubricant oil pump housing and the nozzle of existing lubricating utensil often are connected as a single entity.Such integral structure has improved system reliability, but dismounting is inconvenient, and fuel feeding is distant, has reduced oil outlet pressure.In addition, existing nozzle generally is made of pipe, and it is the lubricant oil inlet opening that the one end connects oil pump, and the other end is the lubricant oil jetburner to the need regions of lubrication.Because the oil droplet in the lubricant oil aerosol that the inlet opening provides is suspended in the gas that transports, the very little and big or small inequality of the diameter of oil droplet, when it was directly injected into regions of lubrication, oil droplet was difficult to accurate control, and the distance of its injection is also shorter.The result usually causes that to need lubricated parts can not get sufficient lubricated, and simultaneously because lubricant oil is mist, easily being diffused into does not need the position of lubricating or remain in the ambient air, has polluted ambient air.

A kind of dismountable nozzle is provided in the patent " CN2711241 ", comprise nozzle body, be arranged on spool, stage clip, lock sheet, spring sheet, filler opening and jet etc. in the nozzle body, by lock sheet stage clip is locked in the inner chamber of spool, thereby realizes that the easy mounted-dismounted type that nozzle is connected with the lubricating pump pump housing connects.Although this patent has realized the summary of nozzle installation, maintenance, and has increased oil outlet pressure, can't drip size by Precise Control of Oil but still exist, avoid the technical problem of the unnecessary loss of Lubricants.

So, needing a kind of Lubricating oil nozzle, lubricant oil oil droplet size can be accurately controlled again in both for convenience detach, replacings, makes the oil droplet in the same size of generation, and can remove mist of oil in the lubricant oil that sprays, and reduces the pollution to environment.

Summary of the invention

The purpose of this utility model provides a kind of jet atomization device that can accurately control the split type charging-up lubricant oil of lubricant oil oil droplet size.

For solving the problems of the technologies described above purpose, the technical solution adopted in the utility model comprises nozzle body, the jet in the nozzle body; Described jet is provided with emitting head, and described emitting head comprises that screw section, cone and centrum are most advanced and sophisticated, and the screw section is fixedly connected with the centrum tip by cone, forms tapered channels, and Lubricants is guided to lubricated target.

Further, described screw section and jet form spirality pipe.

Further, on the outer peripheral surface of described cone root at least one groove is arranged.

Further, described centrum tip is aciculiform.

Further, described tapered channels is not less than one.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, can accurately control lubricant oil oil droplet size, can make again the oil droplet in the same size of generation, can remove mist of oil in the lubricant oil that sprays simultaneously, reduce the pollution to environment; Convenient during replacing; Have characteristics simple in structure, easy to maintenance.

Embodiment

The utility model installs an emitting head additional in the jet inside of split type nozzle, and described emitting head has one or more passages, described oiling agent and transport air-flow along described channel flow.Described passage is diminishing structure, have wide inlet region and the outlet of narrow dimension, wide inlet region is so that oiling agent and transport gas and assemble efficiently, the outlet of narrow dimension forms drop to the needle-shaped ends that oiling agent is sent to described emitting head place, and from then on the needle-shaped ends drop is transported gas and sprays to described target with the drop of a string constant magnitude.

As shown in Figure 1, the existing split type oil nozzle that is provided by patent " CN2711241 ", when lubricant oil enters oil injecting nozzle body 6 through filler opening 5, and the elastic force that lubricating oil pressure is enough to overcome stage clip 3 is, and spool 4 produces motion, and lubricant oil is from jet 7 ejections.Sealing gasket is positioned at the contacting point of oil injecting nozzle body 6 and the pump housing, particularly be positioned at filler opening 5 around, be provided with the screw supporting with described attachment screw in oil injecting nozzle body 6 and the pump housing.Is connected with spring sheet by sealing gasket, screw, stage clip 3, lock sheet 2 and realizes that easy mounted-dismounted type connects.And lubricant oil and gas suck inner chamber by filler opening 5, are injected in by jet 7 afterwards and treat the lubricating detail surface.Here jet 7 is one section elongated tubular product passage.Oil droplet by jet 7 ejections still is vaporific, is unsuitable for accurately lubricating the location.

As shown in Figure 2, the utility model installs emitting head 8 additional in original jet 7, and this emitting head is made by Cuprum alloy usually, and by screw section 9, cone 10 and centrum most advanced and sophisticated 11 forms.There are a series of screw threads that turn around bar screw section 9, itself and the inwall formation spirality pipe 12 of jet 7.Spirality pipe is provided from transport air-flow by the elaioleucite that provides, and condenses together, and forms droplet and assembles along inner walls, and flow to cone 10.The root of cone 10 is provided with groove.The lubricant oil oil droplet is by flowing out in the groove, and assembles along conical surface, at last from most advanced and sophisticated 11 ejections of conically shaped body.Conically shaped body tip 11 is generally aciculiform, because the aggtegation at aciculiform tip 11 makes the lubricated oil droplet size of ejection identical, flow velocity is steady.Circular cone 10 is connected with screw section 9, and the two external diameter size is identical and form with outer tube and to closely cooperate.

Above-mentioned only is an embodiment of the present utility model, but design concept of the present utility model is not limited to this, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
