Description

For filtering liquid fuels, devices are known in which filters are used in the form of a cup with sipes and grids and caps with compressed air to regulate the pressure of the fuel fed to the nozzles, which is heated by a coil.

In the proposed apparatus for filtering and heating oil, related to the above devices, a compressed air reservoir for heating the latter and discharging the walls of the reservoir from pressure is placed inside the apparatus casing.

In FIG. 1 shows a vertical section of the apparatus; FIG. 2 - view1 on top of the filter washer and FIG. 3 is a horizontal section of FIG. one.

The apparatus consists of an iron cylinder 7, closed from below with bottom 5 on the flanges, and from above - with a cap 2, also fixed on the flanges; inside the cylinder / are placed: a reservoir 9 for compressed air, a filter 70 in the form of a cylinder with longitudinal slots 77 in its walls and a coil 72 surrounding as a reservoir 9, a hook and a filter JO (Fig. 1). The filter cylinder W at the top has a socket 75, in which the disk M with concentric cuts (Fig. 2) and the central hole for the bolt 75 passing through the bottom of the filter and carrying the J6 disk at its end is laid flush. The latter serves to clamp the ends of the coarse and fine meshes J7 surrounding the cylinder of the JO filter. A mesh 75 is also placed on the disk J4, on top of which is a slotted disk 75 pressed against the disk M with a bolt 75.

The cast iron bell 2 is provided at the top with an outlet pipe 20 for oil, a manometer and a thermometer. The compressed air tank 9 has a flange for fixing bolts to the bottom 8, equipped with five openings — two openings 5 and 7 for passing the ends of the coil J2, the central opening 5 for the pipe supplying oil to the reservoir 9, opening 3 for the air valve hole 4 for the passage of oil into the cylinder 7 (Fig. 3).

Oil coming from the pump under pressure of 5-7 atm. into cylinder J through the opening 4 of the bottom 8, washing the coil, passes through the fine mesh 77 into the cylinder of the filter JO and through the annular cuts of the disk M and the mesh / 9 into the cap 2 and through the pipe 20 to the place of consumption.

Cold oil from the pump enters the heater and passes through the hole 5 of the bottom 8 into the tank 9.

At the first moment when the tank 9 is empty, when pumping oil into it, the air is compressed, forming an air cushion in its upper part, which regulates the flow of oil in a steady stream (without reflections of interruptions when the pump is running). On the coil 72 passes waste from the pump steam

to heat the oil. An air valve is screwed into the hole 3 of the bottom 8 for periodic replenishment of air in the tank 9 and for the release of oil.
