Abstract

The utility model discloses an oil-returning type mechanical atomizing oil gun, and belongs to the technical field of devices for igniting coal-fired furnaces (such as a coal-fired boiler and a rotary kiln). The oil-returning type mechanical atomizing oil gun is simple in structure and small in resistance. According to the technical scheme, an oil return port and an oil inlet are formed at an oil inlet end of a gun body, one end face of an oil distributing plate is closes to an oil outlet end of the gun body tightly, an atomizing disk is mounted at the other end of the oil distributing plate, a spinning disk is mounted between the atomizing disk and the oil distributing plate, the spinning disk is located inside the atomizing disk, the oil distributing plate, the spinning disk and the atomizing disk are located inside a compression nut, the compression nut is connected to and sleeved on the gun body through threads, and an oil spraying port is mounted at the end, on which the atomizing disk is mounted, of the compression nut. According to the oil-returning type mechanical atomizing oil gun, the quantity of returned oil is adjusted so that the force of the oil gun can be adjusted. The oil-returning type mechanical atomizing oil gun has excellent force adjustment property, is simple in structure and system, and is small in resistance.

Description

A kind of oil return mechanical atomization oil gun

Technical field

A kind of oil return mechanical atomization of the utility model oil gun belongs to coal-fired furnace (coal-burning boiler, rotary kiln etc.) the device technique field that equipment is lighted a fire and ignited, and particularly relates to a kind of mechanical atomization oil gun.

Background technology

As everyone knows, the mechanical atomization oil gun is called torch oil gun again, is a kind of fuel oil (light oil, heavy oil, residual oil, upright wet goods difficult to understand) to be atomized, and makes fuel oil become the um grade particles, by air distribution and ignite, fuel oil is fully burnt; The igniting that is mainly used in coal-fired furnace (coal-burning boiler, rotary kiln etc.) equipment is ignited, and is widely used in the industrial production manufacture process; The existing mechanical atomized oil gun comprises oil barrel, oil inlet pipe, oil return pipe and centrifugal atomizing sheet, and oil inlet pipe all communicates with oil barrel with oil return pipe, and the centrifugal atomizing sheet is positioned at the port of export of oil barrel; In the use fuel oil is entered in the oil barrel by oil inlet pipe, after the rotation of oil barrel high speed produces centrifugal force, the port of export by oil barrel sprays through the centrifugal atomizing sheet, forms the course of work, can the fuel oil of not finishing using in the oil barrel be collected by oil return pipe after the use; Find in this process that it is relatively poor that this kind mechanical atomization oil gun is handled adjusting function, structure and system are comparatively complicated, and resistance is big.

The utility model content

The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of simple in structure, the oil return mechanical atomization oil gun that resistance is little.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of oil return mechanical atomization oil gun, comprise the rifle body, divide food tray, spinning disk, atomizing piece and clamp nut, the oil inlet end of rifle body is provided with oil return opening and oil-in, divide the oil outlet end of an end face of food tray near the rifle body, divide the other end of food tray that atomizing piece is installed, the inside that spinning disk and spinning disk are positioned at atomizing piece also is installed between described atomizing piece and the branch food tray, divide food tray, spinning disk and atomizing piece all are positioned at clamp nut inside and clamp nut is sleeved on by being threaded on the rifle body, and the end end that clamp nut is equipped with atomizing piece is provided with the fluid ejiction opening.

Between described rifle body and the branch food tray sealing gasket is installed.

The utility model is compared the beneficial effect that has with prior art: regulate Oil Gun by regulating recirculating oil quantity, the superior adjusting function of exerting oneself is arranged, structure and system are simple, and resistance is little.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is structural representation of the present utility model.

Among the figure: 1 is the rifle body, and 2 for dividing food tray, and 3 is spinning disk, and 4 is atomizing piece, and 5 is clamp nut, and 6 is oil return opening, and 7 is oil-in, and 8 is sealing gasket.

The specific embodiment

As shown in Figure 1, a kind of oil return mechanical atomization of the utility model oil gun, comprise rifle body 1, divide food tray 2, spinning disk 3, atomizing piece 4 and clamp nut 5, the oil inlet end of rifle body 1 is provided with oil return opening 6 and oil-in 7, divide the oil outlet end of an end face of food tray 2 near rifle body 1, divide the other end of food tray 2 that atomizing piece 4 is installed, the inside that spinning disk 3 and spinning disk 3 are positioned at atomizing piece 4 also is installed between described atomizing piece 4 and the branch food tray 2, divide food tray 2, spinning disk 3 and atomizing piece 4 all are positioned at clamp nut 5 inside and clamp nut 5 is sleeved on by being threaded on the rifle body 1, and the end end that clamp nut 5 is equipped with atomizing piece 4 is provided with the fluid ejiction opening.

Between described rifle body 1 and the branch food tray 2 sealing gasket 8 is installed.

The course of work

Before use, described oil return opening 6 is communicated with in-line and return line by metal hose respectively with oil-in 7, again the ball valve on the in-duct burner is opened, the utility model is slowly inserted from the oil gun stationary pipes, and supporting igniter, flame detector are in place;

Fluid sprays through rifle body 1 oil outlet end, fuel feed hole on minute food tray 2 converges in the corresponding cannelure, tangential slot on spinning disk 3 tangentially flows into the spin chamber and produces strong rotation again, enter atomizing piece 4 at last, through the fluid ejiction opening ejection of atomizing piece 4 center of orifices from clamp nut 5, form a hollow cone shape atomization air flow of being formed by drop, oil stream forms the oil film of turbulence state when just having gone out spout, because making taper oil film surface, the turbulent flow pulsation forms rugged ripple, big speed of related movement and contact surface are arranged between oil film and ambient atmos, make oil film overcome surface tension and be broken into thin oil droplet and form mist of oil;

The utility model is regulated Oil Gun by regulating the oil return flow, compares simple and mechanical atomized oil gun, and the more superior adjusting function of exerting oneself is arranged, and structure and system are simple relatively, and resistance is little.
