Technical Field

The present invention relates to the operation of air-oil separators and oil filters for use in systems requiring oil separation and filtration on a single block.

Background

The oil separation and filtration system is suitable for use in a pressurized air compressor.

The plurality of blocks may be respectively connected to the compressors. In addition, in most compressors, the oil filter and the air-oil separator are separately connected. This situation leads to an increased energy loss in the system. There is a need to develop a system that provides a solution to the problem of high energy losses due to the separate connection of the oil filter and the air-oil separator in the compressor.

Further, in the air-oil separator and the oil filter used in the prior art compressor, a sleeve sheet (also referred to as an outer sheet) is adhered to a bottom plate. This creates a risk of oil leakage and low pressure resistance in the system.

In addition, the oil filters and air-oil separators used in prior systems are discarded at the end of their life. This causes environmental pollution and increases costs.

Documents DE19939970a1 and CN208651170U are examples known in the prior art. CN208651170U describes an air compressor oil filter which can filter metal residues and dust particles in lubricating oil effectively and be replaced promptly and quickly without damaging the compressor. DE19939970a1 describes an oil filter/air separator device for a hydraulic system. The device comprises a housing with an oil filter element.

Disclosure of Invention

There is a need to develop a system for solving the problems associated with the known state of the art systems described above. It is clear that these problems are not solved in the documents describing the known state of the art.

With the invention of the present application, the applicant's objective is to solve these problems and to provide an oil separation and filtration system with thick housing and elements, which has high compressive strength and cycle time, low energy loss, less material handling.

Detailed Description

The present invention relates to the operation of air-oil separators and oil filters for use in systems requiring oil separation and filtration on a single block. In other words, the present invention discloses an oil separation and filtration system having an air-oil separator and an oil filter.

Thanks to the invention, energy losses are reduced and a more compact system is provided for use.

The system according to the invention essentially comprises an air-oil separator element (27), an oil filter element (10), a minimum pressure valve (5), a temperature valve (6) and a block (7) connected to these components.

In the drawings of the present invention, ports a-G are provided.

The general operating principle of the system according to the invention is as follows:

air enters the air-oil separator section through port a (fig. 1D). An air-oil separator element (27) in the first housing (2) separates air and oil from each other. Due to the minimum pressure valve (5) no air flow reaches the set value. Separated air flows out to the system from port B and separated oil flows out to the tank from port H. Oil leaving the tank enters the oil filter element (10) through port F (fig. 3). The heated oil is sent from port C to an external after-cooler according to a set value set by a temperature valve (6) therein. Here, the cooled oil enters through port D, is cleaned by an oil filter element (10) in the second housing (4) and exits from port E and is returned to the screw set of the compressor.

In an embodiment of the invention, the wall thickness of the first housing (2) in the air-oil separator section ranges from 2mm to 15 mm.

In an embodiment of the invention, the wall thickness of the second housing (4) in the oil filter section ranges from 2mm to 10 mm.

The air-oil separator element (27) is shown in fig. 2.

Fig. 2 shows the air-oil separator element (27), the housing upper cover (1), the first housing inner cover (17), a plurality of O-rings (16) providing a seal, the air-oil separator lower cover (37), the air-oil separator upper cover (36), the first housing (2), the tube (20), and the handle line (28).

In an embodiment of the invention, the air-oil separator section (fig. 2) comprises a housing upper cover (1), a first housing inner cover (17), a housing inner cover O-ring (16), and an O-ring (16) providing a seal where the first housing (2) is connected to the block (7). An air-oil separator element (27) in the tube (20) provides separation of air and oil. An O-ring (16) located in the first housing (2) and positioned between the block (7) and the first housing (2) provides a seal.

An air-oil separator element (27) capable of separating air and oil includes an air-oil separator upper cover (36) and an air-oil separator lower cover (37).

In an embodiment of the invention, the number of such shaped pieces ranges from 2 to 15.

In an embodiment of the invention, the air-oil separator element (27) mounted to the first housing (2) is rotated and locked by means of a second passage (33) located below the first housing (2) so as to be prevented from coming out of the first housing (2).

In an embodiment of the invention, the air-oil separator element (27) is fixed to the first housing (2) by means of a handle wire (28) located in an air-oil separator upper cover (36). After the air-oil mixture entering the air-oil separator element (27) is separated, the separated air is sent to the system through a pipe (20) located in the air-oil separator element (27). The tube (20) is mounted on and is an integral part of an air-oil separator upper cover (36). The separated oil is filtered to an air-oil separator upper cover (36) and discharged through an oil discharge hole (29) in the air-oil separator upper cover (36) and fed back to the screw group.

In an embodiment of the invention, the filter element comprises a plurality of oil drain holes (29) in the filter element upper cover (8), the plurality of oil drain holes (29) allowing accumulated oil to drain.

In an embodiment of the present invention, the number of the oil drain holes (29) ranges from 2 to 15.

The oil filter section is shown in fig. 3.

The oil filter section comprises an oil filter element (10) for filtering particles in the oil, a second housing upper cover (3), a second housing inner cover (18), a housing inner cover O-ring (16), and an O-ring (16) providing a seal where the second housing (4) is connected to the block (7).

An oil filter element (10) for retaining particles in oil comprises a filter element upper cover (8), a filter element lower cover (9), a handle line (28) and at least one O-ring (16) for sealing.

A filter element-specific large guide rail (34) formation and a filter element-specific small guide rail (35) formation on the filter element lower cover (9) enable the oil filter element (10) to enter the second housing (4) by means of a first passage (32) and a second passage (33) in the second housing (4).

In an embodiment of the invention, the number of such shaped pieces ranges from 2 to 15.

In an embodiment of the invention, the filter element lower cover (9) and the filter element upper cover (8) are aluminium, polyamide, stainless steel or sheet metal.

In an embodiment of the invention, the oil filter element (10) mounted to the second housing (4) is rotated and locked by means of a second channel (33) below the second housing (4) and prevented from coming out of the second housing (4). The oil filter element (10) is easily mounted and locked in the second housing (4) by means of a handle line (28) on the filter element upper cover (8). When oil entering the second housing (4) passes through the oil filter element (10), the particles contained therein are retained by the oil filter element (10).

In an embodiment of the invention, the oil filter element (10) is installed by locking it into the second housing (4) after assembly. In another embodiment of the invention, the air-oil separator element (27) is locked after insertion into the first housing (2).

Fig. 9 shows a view of the filter element lower cover (9) performing oil filtration in the system of the present invention, the filter element lower cover (9) comprising a safety ring (11), a lower gasket (12), an upper gasket (13), a nitrile gasket (14) and a spring (15). A lower gasket (12), an upper gasket (13) and a nitrile gasket (14) are provided in the filter element lower cover (9), and compression of a spring (15) is provided. These components are mounted to a channel on the filter element lower cover (9) and locked with a safety ring (11) and act as pressure valves. The adjusting spring (15) is therefore compressed at a certain pressure according to a set value and allows the passage of air.

In summary, the present invention is an oil separation and filtration system having an air-oil separator and an oil filter, characterized by:

an air-oil separator element (27), the air-oil separator element (27) separating oil droplets from air,

an oil filter element (10), the oil filter element (10) filtering particles contained in oil,

a block (7), the block (7) maintaining the air-oil separator element (27) and the oil filter element (10) working together,

a plurality of O-rings (16), the plurality of O-rings (16) acting as fasteners,

a first housing (2) in which an air-oil separator element (27) operates,

a second housing (4), in which second housing (4) an oil filter element (10) operates; a minimum pressure valve (5), the minimum pressure valve (5) not allowing air to pass according to a set value,

a temperature valve (6), which temperature valve (6) opens at a predetermined temperature according to a set value, allowing the heated oil to proceed to a final cooler,

for each of the air-oil separator element (27) and the oil filter element (10), a handle wire (28) engages and locks them to the first housing (2) and the second housing (4), respectively.

Due to the system according to the invention, the oil filter and the air-oil separator are connected together to provide a more compact structure and to reduce energy losses. Furthermore, the thick housing used in the block increases the compressive strength and cycle time, and saves space in the compressor, since the elements that have completed their life are in the housing and will be removed with the housing.

Furthermore, the component is only disposed in the housing when it reaches the end of its life. In this case, less material is discarded and environmental pollution is reduced.
