Description

A FILTER SYSTEM COMPRISING A SINGLE FILTER BLOCK AND DOUBLE
FILTER ELEMENT
Field of the Invention
The invention relates to a filter system comprising a single filter block and double filter element in order to increase the capacity of the line filters used for cleaning pressurized air and separating it from impurities contained therein.
Known State of the Art
Pressurized air systems include filters located on the line, which provide filtration of pressurized air.
The equipment located on the pressurized air systems should be selected in accordance with the system capacity. As the system capacity increases, the capacities of the used pressurized air filters increase and thereby both their dimensions and connection diameters increase. After a certain capacity increase, filter and internal element configuration cannot meet this increase in capacity. Thus, there is a need to use a pressurized tank comprising flange inlet-outlet and multiple elements. This pressurized tank is described as a flanged filter. The use of flanged filters is very expensive and is not volumetrically-massively efficient solution. When service is required, high service costs arise due to the volume-mass disadvantages.
An example of the known state of the art include the document no. US2019105592A. This document features a flange, filter placement, a device for separating oil aerosol from air, and the manufacturing method for filter insertion. It is noted that the flange has a solid structure. It is apparent from this document that the use of flanged filters is quite expensive and there is no current solution to the problem of not being volumetrically-massively efficient.
While the use of flanged filter, which is used to increase the capacity in the present technique, aims to solve the problem, it causes other problems as mentioned above. Other solutions are needed to increase the capacity of the line filters used to eliminate the need for the use of flanged filters and to clean the pressurized air and to separate foreign substances contained therein.

In one embodiment of the invention, each inlet slot in the filter connecting body (1) comprises a threaded and coupling connection body.
In an embodiment of the invention, there is an inlet port (7) that provides one pressurized air inlet and an outlet port (8) that provides one pressurized air outlet, on the filter connection body (1). In the system according to the invention, the filter connection body (1) transfers the entering pressurized air to the filter element in an equal amount.
In an embodiment of the invention, there is at least one drain port located the bottom of the filter housing pipe to drain liquids such as filtered oil and water in the air.
In an embodiment of the invention, the filter element comprises a bottom cover and a top cover.
In one embodiment of the invention, the filter element is of two different types, the primary filter element (3) and the secondary filter element (13).
In an embodiment of the invention, the primary filter element (3) comprises the primary upper cover (10), wherein it placed in the primary filter housing pipe (2) comprising secondary channel (12). Said primary filter element (3) is shown in figures 3 and 4.
An embodiment of the invention comprises more than one primary channels (11) located on a primary bottom cover (9) for placing the primary filter element (3) to the primary filter housing pipe (2). In an embodiment of the invention, the number of primary channels (11) ranges from 2 to 15.
In an embodiment of the invention, it comprises a secondary channel (12) located under the primary filter housing pipe (2) that is compatible with the primary channel (11), which provides that the primary filter element (3) mounted on the primary filter housing pipe (2) is rotary locked and prevented from leaving the primary filter casing pipe (2). In an embodiment of the invention, the secondary filter element (13) comprises the secondary upper cover (15) having a tertiary channel (16), wherein it is placed in the secondary filter housing pipe (14) comprising the quaternary channel (17). Said secondary filter element (13) and secondary filter housing pipe (14) are shown in figures 11 and 12.
An embodiment of the invention comprises more than one tertiary channels (16) located on a secondary top cover (15) in order to place the secondary filter element (13) to the secondary filter housing pipe (14).
In an embodiment of the invention, it comprises a quaternary channel (17) located under the secondary filter housing pipe (14) that is compatible with the tertiary channel (16), which ensures that the secondary filter element (13) mounted on the secondary filter housing pipe (14) is fitting and prevents it from leaving the primary filter casing pipe (14).
In an embodiment, there is a handle wire on the upper cover of filter element to lock the filter element on the filter housing pipe by mounting.
In an embodiment of the invention, the wall thickness of the filter housing pipe is in the range of 2 to 15 mm.
In an embodiment of the invention, the bottom cover and the top cover comprises aluminum, polyamide, stainless steel or sheet metal.
The filter elements in the pressurized air filter have different structures for different applications. Accordingly, for some filter elements, while pressurized air penetrates into the filter element first (working from inside to outside), in different applications, the pressurized air penetrates to the outer surface of the filter element (working from outside to inside).
Pressurized air entering through the inlet port (7) located on the filter connection body (1) is distributed equally to the two filter elements due to the two different filter housing pipes in the body. Equally distributed pressurized air reaches the filter element surface. Air is filtered on the filter element and collected on the other surface of the filter element and directed towards the outlet. The pressurized air filtered in both filter elements merges in the filter connection body (1) and leaves the system through the outlet port (8).
In the invention of the present application, while pressurized air is filtered, liquids such as oil and water in the air are collected on the surface of the filter element. These collected fluids flow into the filter housing pipe and accumulates at the bottom and the accumulated liquid is discharged through the drain port located at the bottom of the filter housing pipe.
Figure 8 shows the first air inlet surface (1-A) and the second air inlet surface (1-B), located in the filter connection body (1). By means of these surfaces, pressurized air entering from the inlet port (7) is distributed equally to both filters.
Figure 9 shows the first air outlet surface (1-C) and the second air outlet surface (1-D), located in the filter connection body (1). By means of these surfaces, the compressed air is directed to the outlet port (8) and then exits from the filter elements.
The improved filter system provides that the pressurized air is distributed equally across the filter elements. Since a single body and a single filter/filter element have been used in the prior art, there are no developments regarding the even distribution of air.
The invention, in brief, relates to a filter system, wherein the filter system comprises multiple filter elements, which has a bottom cover and a top cover that separates impurities such as oil, water and particles from the air from the pressurized air; a filter connection body (1) that provides connection of the filter elements to the compressed air line with a single body, directs the flow of compressed air, and includes an inlet socket for the inlet of each filter element; an inlet port (7) providing the pressurized air inlet and an outlet port (8) providing the pressurized air outlet located on the filter connection body (1); more than one filter housing pipe connected to the filter connection body (1), in which each filter element operates; multiple sealing elements for the connection of the filter element and the filter housing pipe to the filter connecting body (1).
