Abstract

The utility model relates to a bituminous concrete mixing equipment burning device, comprising a spray pistol (4) connected with an oil supply pipe (7) and an oil return pipe (8), entering a combustion chamber (3) through ducts and aligning to a combustion chamber (2) via an oil return metering-orifice (16), an atomising sheet (15) and alight flames, a controlling oil passage is provided with an adjusting valve (9), an oil pump (10) and an oil tank (11), a blower system is provided with a blower fan (5), an air funnel (17), an air door (19) and an adjusting mechanism (20), the combustion chamber (3) is provided with an outward guide blade (21) and an inward guide blade (13), causing the quadric atomisation of alight oil materials achieves the flame shortness, producing good effect with completely combusting and saving energy. The utility model has the advantages of reasonable structure and high heat efficiency and is an ideal bituminous concrete mixing equipment burning device.

Description

Bituminous concrete mixing equipment burning device

The utility model is a kind of flame burner, and particularly bituminous concrete mixing apparatus burner belongs to highway machinery equipment.

At present, the normal burner that adopts in the pitch prill concrete mixing plant, as revolve co-annular burner, the steam atomising burner, pressure-air atomising burners etc. are common, and to exist burning not thorough, excessive oil consumption, in addition because the long directly contact of flame aggregate, cause incomplete combustion, and the loss energy, the while also influences the quality of finished product material.

The purpose of this utility model is for overcoming the existing weak point of said burner, provide the good combustion efficiency of a kind of atomization quality good, flame weak point, thermal efficiency height, the pitch prill concrete mixing plant burner of energy conservation.

Task of the present utility model realizes as follows, in the incendiary oil process, employing is with the mechanism of twice atomizing of oil plant, primary atomization adopts " pressure type atomizing ", be about to hydraulic oil and enter spray gun, thread a pipe and to the aperture that is provided with a circle, enter the spin chamber, form at a high speed rotation oil stream and form vaporificly from the ejection of atomizing piece aperture, meet the impact of high velocity air again, further mist of oil is dripped and smash when the ejection mist of oil, realize secondary-atomizing, make oil plant reach abundant atomizing, in addition, also adopt curved surface rotary type blade guiding air distribution to make mist of oil torch rotation ejection, be that incendivity is complete, and can shorten axial flame distance.

Below with reference to drawings and Examples the utility model is described in further details.

Fig. 1 is the utility model and accessory system schematic diagram.

Fig. 2 is the utility model longitudinal plan.

Fig. 3 is the utility model guide vane sectional schematic diagram.

Among the figure 1, cylinder; 2, combustion chamber; 3, burner; 4, spray gun; 5, blower fan; 6, pressure meter; 7, oil return pipe; 8, fuel feed pump, 9, control valve; 10, oil pump; 11, fuel tank; 12, outer guide vane; 13, interior guide vane; 14, housing; 15, atomizing piece; 16, oil return metering-orifice; 17, air duct; 18, adjust pull bar; 19, air door; 20, air door adjusting lever.

As scheming: 1, the utility model shown in Figure 2 comprises that is connected to a fuel feed pump (7), the spray gun (4) of oil return pipe (8), thread a pipe and enter burner (3), and through oil return metering-orifice (16) atomizing piece (15), mist of oil is lighted formation flame and is axially aligned combustion chamber (2) to cylinder (1), control valve (9) is arranged in the control oil channel, oil pump (10), fuel tank (11), and the blower fan in the blower system (5) air duct (17), air door (19) and air door guiding mechanism (20), its special character is, has air duct (17) to enter outside logical live guide vane (12) and interior guide vane (13) in burner (3) and forms.

In the utility model technical solution, blowing out high velocity air by blower fan (5) enters in burner (3) housing (14), guide vane (13) and the outer guide vane (13) that is positioned at cylindrical are formed in its exit is respectively equipped with by the curved surface rotary type of central part, make the gas shock mist of oil, and formation secondary-atomizing eddy flow mist of oil torch, cause the length that shortens jet flames, and can adjust inside and outside guide vane (13) (12) by air door guiding mechanism (20) and move forward and backward.

Claims
