Description

Oil phase filtering device

Technical Field

The utility model relates to the field of emulsion explosive raw materials, in particular to an oil phase filtering device.

Background

The emulsion explosive is characterized in that droplets of an oxidant salt aqueous solution are uniformly dispersed in an oil phase continuous medium containing porous substances such as dispersed bubbles or hollow glass beads by the action of an emulsifier to form a water-in-oil emulsion explosive. However, in the actual production process, iron substances are inevitably mixed, for example, when the oil phase is pumped into a packing box from the heat-insulating tank body, the iron substances in the tank body, the pipeline, the pump, the valve, the metal sealing element and other equipment easily flow into the oil phase product, so that the oil phase product is unqualified, and the explosive production is brought with great potential safety hazard.

FIG. 2 is a sectional view of the basket-type filtering net of the present invention;

in the figure: the filter comprises a filter shell 1, a basket type filter screen 2, a supporting flange 3, an annular clamping plate 4, an inlet pipe 5, an outlet pipe 6, a cover body 7, a impurity collecting hopper 8, a conical body 9, a pull handle 10, a sealing ring 11, filter holes 12 and a filter screen 13.

Detailed Description

The utility model is described in further detail below with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 and 2, an oil phase filtering device comprises a filter housing 1 and a basket type filter screen 2 arranged inside the filter housing 1, wherein the basket type filter screen 2 is clamped on an annular clamping plate 4 fixed on the inner wall of the filter housing 1 through a supporting flange 3 obliquely arranged at the top of the basket type filter screen 2, a cylindrical impurity collecting hopper 8 is arranged at the bottom end inside the basket type filter screen 2, a conical body 9 is arranged at the bottom of the impurity collecting hopper 8, a pull handle 10 is fixed at the top of the conical body 9, a sealing ring 11 in contact with the filter housing 1 is arranged on the outer side of the impurity collecting hopper 8, a filtering hole 12 communicated with the inside of the impurity collecting hopper 8 is annularly arranged at the root of the side end of the impurity collecting hopper 8, and a filter screen 13 is arranged on the filtering hole 12.
