[0029] Example 1

[0030] like Figures 1-5 As shown, this utility model provides a technical solution:

[0031] An integrated structure filter for a wind power lubrication system includes, but is not limited to, a filter cylinder 1, a filter element 2, and a filter cylinder cover plate 3; the filter cylinder cover plate 3 is connected to the upper end flange of the filter cylinder 1, and a safety valve assembly mounting seat 4 and a temperature control valve assembly mounting seat 5 are provided on the end of the filter cylinder 1 away from the filter cylinder cover plate 3; the safety valve assembly mounting seat 4 and the temperature control valve assembly mounting seat 5 are integrally formed with the filter cylinder 1, and the filter element 2 is disposed in the filter cylinder 1.

[0032] Based on the above structure, the filter cartridge assembly's cylinder, base, and retaining ring structure are first integrated into a single design, reducing threaded connections and sealing structures. This solution eliminates the valve block structure of the safety valve 49 assembly, adjusting the valve's mounting position to the filter cartridge assembly. A valve mounting position is constructed on the filter cartridge housing, and the mounting position is simplified based on the valve's structural shape. Simultaneously, the temperature control valve 53 assembly's valve block is eliminated, and the temperature control valve 53 mounting position is integrated with the bottom structure of the filter cartridge, reducing the overall structural complexity, making the entire structure more compact, and requiring fewer assembly points, effectively improving installation efficiency. The filter cartridge top cover is changed from a threaded connection to a bolted fastening connection, improving overall sealing reliability.

[0033] As an example, a cylindrical mounting base 6 is also provided on the side wall of the filter cartridge 1, and the cylindrical mounting base 6 and the safety valve assembly mounting base 4 are symmetrically arranged along the center of the filter cartridge 1.

[0034] Based on the above structure, the cylindrical mounting base 6 can be set to facilitate the connection between the filter and the external installation interface. At the same time, the cylindrical mounting base 6 and the safety valve assembly mounting base 4 are symmetrically arranged along the center of the filter cylinder 1, which can avoid interference between the safety valve assembly mounting base 4 and the outside world after the filter cylinder 1 is installed.

[0035] As an example, the safety valve assembly mounting base 4 may specifically include a first pressure measuring chamber 41, a second pressure measuring chamber 42, a first valve seat 43, a second valve seat 44, and a third valve seat 45; the first pressure measuring chamber 41, the second pressure measuring chamber 42, the first valve seat 43, the second valve seat 44, and the third valve seat 45 are arranged sequentially along the side wall of the filter cartridge 1, and the first pressure measuring chamber 41, the second pressure measuring chamber 42, the first valve seat 43, the second valve seat 44, and the third valve seat 45 are on the same straight line;

[0036] A pressure transmitter 46 is installed in the first pressure measuring chamber 41, a pressure measuring connector 47 is installed in the second pressure measuring chamber 42, a first check valve 48 is installed in the first valve seat 43, a safety valve 49 is installed in the second valve seat 44, and a second check valve 410 is installed in the third valve seat 45.

[0037] Based on the above structure, by integrating the valve seats of each assembly component onto the side wall of the filter cartridge 1, on the one hand, the overall material usage can be reduced and the overall tightness can be improved; on the other hand, the assembly difficulty in the later stage can be reduced and the installation efficiency can be improved.

[0038] As an example, the temperature control valve assembly mounting base 5 may specifically include a first cavity 51 and a second cavity 52. ​​The first cavity 51 is coaxially arranged with the bottom of the filter cartridge 1, and the second cavity 52 is arranged on the side wall of the first cavity 51 and perpendicular to the first cavity 51. A temperature control valve 53 is arranged in the second cavity 52.

[0039] A first end plate 54 is provided at the end of the second cavity 52 away from the first cavity 51, and the first end plate 54 and the second cavity 52 are connected by bolts.

[0040] A second end plate 55 is provided at the end of the first cavity 51 away from the filter cartridge 1. The second end plate 55 is connected to the first cavity 51 by bolts. A sampling connector 57 is also provided on the second end plate 55. The sampling connector 57 is set on the second end plate 55 by springs.

[0041] Liquid outlets are provided on the side walls of the first cavity 51 and the second cavity 52.

[0042] The first cavity 51, the second cavity 52, and the filter cartridge 1 are integrally formed.

[0043] Based on the above structure, this solution integrates the originally dispersed multiple components to form a first cavity 51 and a second cavity 52. ​​Various functional components are set in the first cavity 51 and the second cavity 52, which reduces the installation difficulty of the entire structure and improves the overall sealing performance.

[0044] As an example, multiple first bolt holes are provided in the circumferential position of the filter cartridge cover plate 3, and multiple second bolt holes that mate with the first bolt holes are provided in the end plate of the filter cartridge 1. The filter cartridge cover plate 3 and the filter cartridge 1 are connected as a whole by passing the locking screw 31 through the first bolt holes and the second bolt holes; a rubber O-ring is provided between the filter cartridge cover plate and the filter cartridge 1.

[0045] Based on the above structure, this solution connects the filter cartridge cover plate 3 and the filter cartridge 1 with bolts. Compared with the traditional threaded connection between the filter cartridge cover plate 3 and the filter cartridge, this makes the structure more stable. At the same time, rubber O-rings are used for sealing, changing the original sealing method from axial sealing to radial sealing, which improves the sealing reliability.

[0046] As an example, the filter element 2 may include a filter element seat 21, a coarse filter 22, a fine filter 23, a bypass valve 24, and a filter element cover 25; the filter element seat 21 is provided with an annular groove that mates with the coarse filter 22 and the fine filter 23, the coarse filter 22 is fitted inside the fine filter 23, the filter element cover 25 is located on the end of the fine filter 23 away from the filter element seat 21, and the bypass valve 24 is located inside the filter element cover 25.

[0047] Based on the above structure, during filtration, the filtrate enters the filter cylinder 1 from the side wall of the filter cylinder 1, is filtered by the fine filter 23, and after passing through the coarse filter 22, enters the temperature control valve 53 from the bottom of the filter cylinder 1, and finally exits from the outlet. In this scheme, usually only the fine filter 23 is needed to complete the filtration operation. The coarse filter 22 is used for filtration in emergency situations. For example, when the fine filter 23 reaches its maximum dirt-holding capacity and cannot perform filtration, the filtrate will force the bypass valve 24 at the top to open and directly enter the inner cylinder of the fine filter 23, and then be discharged outward after passing through the coarse filter 22.

[0048] As an example, a first bushing 32 is provided at the center of the filter cartridge cover plate 3. The first bushing 32 extends a predetermined distance away from the filter cartridge cover plate 3. A first snap-fit ​​seat that mates with the first bushing 32 is provided on the bypass valve 24.

[0049] Based on the above structure, the upper end of the filter element 2 is fixed by the cooperation of the first snap-fit ​​seat and the first bushing 32, so that the filter element 2 can perform stable filtration in the filter cylinder 1.

[0050] As an example, a second bushing 33 is provided at the bottom of the filter cartridge 1, and the second bushing 33 extends a predetermined distance away from the first cavity 51; a second snap-fit ​​seat is provided on the filter element seat 21 to cooperate with the second bushing 33.

[0051] Based on the above structure, the lower end of the filter element 2 is fixed by the cooperation of the second bushing 33 and the second snap-fit ​​seat, so that the entire filter element 2 is firmly fixed.

[0052] As an example, a ball valve 7 and a differential pressure switch 8 can also be installed on the outside of the filter cartridge 1 to ensure the integrity of the overall function.

[0053] The main structural improvement in this design is the integration and merging of the installation structures of safety valve 49, filter cartridge, and temperature control valve 53 into a single, integrated structure. The filter housing serves as the main load-bearing component for the entire filter, and the installation of parts, fluid flow channels, pressure bearing of the container, and filter mounting are all achieved through this integrated housing. The integrated housing is constructed using gravity casting of aluminum alloy. The integrated structure mainly consists of three parts: the filter cover, the housing, and the bottom sealing plate. All other openings are used for the installation of functional components.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
