Description

The inventive utility model relates to the field of filtering technical oily liquids and can be used in instrumentation and other industries where fine purification of liquids such as, for example, technical oils used in micromechanics is necessary.

A known filter for fine purification of liquid and / or gas (Patent RU No. 2242270 IPC ⁷ B01D 61/18 publ. December 20, 2004), comprising a housing, a filtrate outlet, a filter element made in the form of membranes from a microcapillary film; the filter is multi-block and operates under excessive pressure of a liquid or gas.

The disadvantage of the claimed technical solution is its multi-stage design, which is not suitable for small volumes of filtered fluids due to losses on each filter, in addition, the proposed technical solution involves the presence of electric pumps for supplying filtered fluids.

A device for filtering liquids (Aut. St. USSR No. 1711907 class. A61M 3/00 publ. 02/15/1992), containing a piston, a cylinder with a tip, a sleeve with a filter, and the sleeve with the filter is installed using a threaded connection inside the cylinder on the tip.

The main disadvantage of the prototype is the inability to filter technical oils due to their low fluidity (the approximate manual filtration time of 20 ml of oils is about 7-10 hours).

The objective of the utility model is to create such a device that would eliminate manual labor when filtering oils, reduce the filtering time, and it would be autonomous and non-volatile.

Thus, the proposed device for filtering oily liquid, containing a piston, a cylinder with a tip, a filter, contains a base with handles, to which is attached a housing with a recess for a container for collecting filtered fluid, installed between the spring gasket and the liner for free placement of the filter in it, made in the form of a syringe nozzle, mounted on the tip of the cylinder, and the cylinder of the syringe lies with its rim on a support in the recess, and the piston rod extended up to the stop abuts against the square, eplenny on a rack of variable height associated with the housing and configured as a ball guide, freely mounted in a stationary housing having a base and movable in height under the load placed on the suspension, placed in its turn on the rectangle on the axis of the strut.

In addition, the drain hole of the syringe nozzle is located opposite the inlet opening of the container for collecting the filtered fluid, and the spring gasket on which the container for collecting fluid is installed, compresses the latter to the protrusion of the filter insert.

As a spring pad, a foam polymer material is used - foam.

The volume of the container for collecting the filtered liquid exceeds the volume of the syringe.

In FIG. 1 shows a General view of the device with an angular section.

In FIG. 2 shows a section through the device AA of FIG. 3.

In FIG. 3 is a sectional view of the apparatus CC of FIG. 2.

A device for filtering oily liquid consists of a base 1 with handles 2, to which is attached a housing 3 with a recess 4 for a container 5 for collecting filtered fluid, installed between the spring pad 6 and the insert 7 to accommodate the filter, made in the form of a syringe nozzle 8, mounted on the tip 9 of the syringe 10, the cylinder 11 of which with its rim 12 lies on the support 13 in the recess 14, and the rod 15 extended up to the stop abuts the angle 16 mounted on a ball guide 17 located in the rack 18 and connected with the body ohm 3. rectangle 16 on an axis 19 disposed hanger 20 for holding goods 21.

Device operation

Before operating the device, suspensions 20 and weights 21 must be removed. In the recess 4 on the spring gasket 6 set the tank 5, moving first the neck, and then the base. In the insert 7, a filter nozzle 8 is placed, articulated through a tip 9 with a syringe 10 filled with filtered fluid, while the rim 12 of the syringe 10 is laid in the recess 14 on the support 13, while raising the angle 16, and insert the rod 15 of the syringe 10 into the recess of the axis 19 Then, suspension 20 is mounted on axis 19 and weights 21 are hung on it.

The installation begins to work under the action of weights 21 and the ball guide 17 together with the rod 15 of the syringe 10 will smoothly go down the rack 18, mounted on the base 1, until the syringe 10 is completely empty.

The spring gasket was made of PVCE MPTU 6-05-1269-69 foam, which has shock absorbing properties, and a Millipore nozzle with pore sizes of 0.45 μm was used as a filter nozzle.

Prior to the development of this device, manual filtering of 20 ml of liquid through a filter nozzle with a pore size of 0.45 μm took 6-7 hours, while on the proposed device the same operation can be performed in 1 hour without the use of any manual labor.

The optimal calculated weight of the cargo with this filtering was 8-10 kg.

Thus, the proposed device for cleaning an oily liquid due to the presence of a simple structure, consisting of a suspension with a load placed on it, eliminates the time-consuming manual filtering of such liquids and significantly reduces the filtering time. In addition, the proposed device is autonomous and does not require any energy costs.
