Definitions
- the invention relates to a blown-air and liquid-fuel burner Domestic fuel type, light fuel oil, heavy fuel oil or kerosene, comprising more particularly a pump driven by a motor engaged with a pump shaft to circulate a liquid fuel of the type previously indicated between a tubing connected to a socket inlet of the pump and a tubing connected to an outlet of the pump, the latter being provided with a stuffing box body extending parallel to the pump shaft to fit in a axial direction in a housing of a support piece disposed between pump and motor and to be maintained in the housing by clamping means extending in a plane perpendicular to the direction axial to lock the gland body into the housing of the support piece.
- liquid fuel contaminates the parts surrounding the pump when removing tubing.
- the object of the invention is to overcome this disadvantage.
- the subject of the invention is a burner of the recalled type previously, characterized in that it comprises a recuperator for recover the liquid fuel escaping from the pump when the tubing s are removed from the inlet or outlet ports, provided with a opening to be centered around the gland body and in support against the pump and the support piece when the stuffing box body is clamped in the housing by the clamping means and provided with clearances for passage or access to the clamping means.
- Figure 1 shows a forced air and domestic fuel burner according to the invention.
- FIG. 2 shows an exploded view of the pump, the drive trainer and the liquid fuel recuperator of the burner illustrated in FIG.
- Figure 3 shows the elements of Figure 2 but in the assembled position.
- Figures 4 and 5 show in section assembled elements according to the figure 3.
- FIG. 6 is a detailed view of the recuperator illustrated in FIG.
- a blast and fuel burner liquid comprises a pump 1, for example geared, driven by a motor 3 engaged with a pump shaft 5 to put into circulation a liquid fuel of the domestic fuel type, light fuel oil, heavy fuel oil or kerosene, between a tubing 7 connected to an input socket 9 of the pump and a pipe 11 connected to an outlet 12,13,14 of the pump.
- the liquid fuel flow rate is typically between 1 and 1500 liters per hour.
- Pump 1 is provided with a gland body 15 extending parallel to the pump shaft 5 to fit into a housing 17 a support piece 19 disposed between the pump 1 and the motor 3.
- the support piece 19 is a rear flange 19a engine.
- the invention applies also to a burner in which the support piece 19 and a housing of volute housing a turbine to circulate the air used for combustion of the liquid fuel.
- the invention still applies to a burner in which the support piece 19 is a cover 19b of such casing of volute or air circuit.
- FIGS. 4 and 5 A link member between the motor 3 and the pump shaft 5 is referenced 4.
- the pump 1 is held in the housing 17 of the support part 19 by clamping means 21, for example screws, extending in a plane P perpendicular to an axial direction D of the housing 17 receiving the gland body 15 for locking said body 15 in said housing 17 of the support piece 19.
- the clamping screws 21 are screwed into threaded bores 22 formed in a guide portion 16 of the housing 17.
- the burner comprises a recuperator 23 to recover the liquid fuel escaping from the pump 1 when the tubing s 7.11 are removed from the input jacks 9 or output 13.
- the recuperator is provided with an opening 25 to be centered around the part of guide 16 of the housing 17.
- the recuperator 23 bears against the pump 1 and the support piece 19, for example via a flange 27 surrounding a bottom 26 of the recuperator 23, when the body of gland 15 is clamped in the housing 17 by the means of tightening 21.
- the recuperator 23 is provided with clearances 29 extending in the plane perpendicular to the axial direction D of the housing 17 of the stuffing box body 15.
- the support of the flange 27 on the pump 1 and the support piece 19 allows block the recuperator 23 in translation parallel to the pump shaft 5 when the gland body 15 is locked in the housing 17 of the support piece 19 by the clamping screws 21.
- the recuperator 23 is locked in rotation relative to the support part 19 by two notches 33, 35 carried respectively by the support piece 19 and by the recuperator 23.
- notch 33 of the support piece 19 is pierced to form the threaded bore 22 of the housing 17 and the notch 35 of the recuperator 23 is formed by the clearance 29 for passage or access to the clamping screw 21.
- the recuperator 23 also includes an evacuation 31 to evacuate recovered liquid fuel to a tank via a tubing connected to the outlet 31.
- the evacuation 31 comprises a spout 30 which has a grip 32 to be connected to a liquid fuel evacuation pipe recovered.
- the flow of liquid fuel in the bottom 26 of the recuperator 23 towards the evacuation 31 is done by gravity.
- the rim 27 surrounding the bottom 26 of the recuperator or the nozzle 30 of the evacuation 31 is advantageously inclined relative to the plane defined by the bottom 26 to allow to use the recuperator 23 in a position of the pump shaft 5 inclined by ratio to the vertical of the place where the burner is installed.
- the recuperator 23 is preferably manufactured according to a method of plastic injection molding.
- the burner according to the invention is used more particularly when pump disassembly requiring removal of connected tubing at the inlet and outlet ports of the pump or when cleaning the filter pump.
