Title of the invention: A stainless steel double cylinder parallel filter Technical field

[0001] The utility model relates to the technical field of filters, in particular a parallel double-cylinder filter made of stainless steel. The background technique

[0002] The double-cylinder filter, also known as the double-cylinder oil return line filter, consists of two single-cylinder filters and a two-position, six-way reversing valve. The filter has a simple structure and is easy to use. It is equipped with a bypass valve and a filter element pollution and blockage transmitter to ensure the safe operation of the system.

[0003] Usually, the double-cylinder filter is installed on the oil return line of the hydraulic system. The double-cylinder filter can filter abrasive particles and other contaminants generated during the working process of various hydraulic components. After long-term use, a large amount of abrasive matter remains on the surface of the filter element, which needs to be cleaned or replaced. The existing treatment methods are generally direct replacement or cleaning after disassembly, which makes the use of the filter very inconvenient. The contents of the utility model

There is a cleaning mechanism inside the left and right filter cylinders, and the cleaning mechanism comprises two front and rear sliding rods. These two sliding rods are fixedly connected to the left and right sides of the inner wall of the filter cylinder and have a mounting plate slidably connected to the surface. Two sliding rods are symmetrically arranged under the inside of the filter cylinder, and the corresponding sliding rods are also slidably connected to a mounting plate.In addition, the surfaces of the two sliding rods located on the left and right sides of the mounting plate are equipped with vibrating springs. And a . A mounting slot is provided in the middle of the mounting plate. Thanks to the mounting mechanism, the filter element is installed between the upper and lower mounting plates.

[0006] Furthermore, a drive motor is fixedly connected to the left side of the inner wall of the filter cylinder via a motor frame. A cam is fixedly connected to the output end of the drive motor, and the side of the cam is in contact with the left side of the mounting plate.

[0007] Furthermore, the mounting mechanism comprises four threaded rods, which are fixedly connected to the inner wall of the mounting plate at equal distances. The surface of the threaded rod is threadedly connected to a threaded sleeve, and the threaded sleeve penetrates the mounting plate and extends toward the inside of the mounting slot. One end of the four threaded sleeves located inside the mounting slot is fixedly connected to an arc pressure plate.

[0008] Furthermore, the surfaces of the four threaded rods are all fixedly connected to the driven gears. The top of the inner wall of the mounting plate is slidably connected to the first annular gear via an annular chute. The top of the first annular gear is fixedly connected to the second annular gear. The second annular gear meshes with the four driven gears for transmission.

[0009] Furthermore, the bottom of the inner wall of the mounting plate located below is rotatably connected to a rotating rod. The rotating rod penetrates the lower mounting plate and the upper mounting plate, and extends above the upper mounting plate. The upper end of the threaded sleeve located above the rotating rod is fixedly connected to a rotating handle.

[0010] Furthermore, the surface of the rotating rod located inside the upper and lower mounting plates is fixedly connected to the driving gear.

Specific implementation methods

[0020] The technical solutions in the implementation examples of the utility model will be clearly and completely described below with reference to the illustrations in the implementation examples of the utility model. Obviously, the described implementation examples represent only some, and not all, of the implementation examples of the utility model. Based on the implementation examples of the utility model, all other implementation examples obtained by ordinary technicians in this field without creative efforts fall within the scope of protection of the utility model.

[0021] This parallel double cylinder stainless steel filter provides two technical solutions:

[0022] [Fig. l]-3 shows the first implementation method: the filter comprises two left and right filter cylinders (1), an oil inlet pipe (2), an oil discharge pipe (3), a three-way valve (4) and a filter element (7). The two left and right filter cylinders (1) share an oil inlet pipe (2), and a three-way valve (4) is provided on the oil inlet pipe (2). The oil discharge pipe (3) is arranged in the same way as the oil inlet pipe (2). There is a cleaning mechanism (5) inside the left and right filter cylinders (1), and the cleaning mechanism (5) comprises two front and rear sliding rods (51). These two sliding rods (51) are fixedly connected to the left and right sides of the inner wall of the filter cylinder (1) and have a mounting plate (52) slidably connected to the surface.Two sliding rods (51) are symmetrically arranged under the inside of the filter cylinder (1), and the corresponding sliding rods (51) are also slidably connected to a mounting plate (52). In addition, the surfaces of the two sliding rods (51) located on the left and right sides of the mounting plate (52) are equipped with vibrating springs (53). A mounting slot (54) is provided in the middle of the mounting plate (52). The filter element (7) is installed between the upper and lower mounting plates (52) via the mounting mechanism (6). A driving motor (55) is fixedly connected to the left side of the inner wall of the filter cylinder (1) via a motor frame. A cam (56) is fixedly connected to the output end of the driving motor (55), and the side of the cam (56) is in contact with the left side of the mounting plate (52). .

[0023] This stainless steel double-cylinder parallel filter starts the drive motor (55) to rotate the cam (56) after the filter element (7) has been used for a long time. The cam (56) is in contact with the side of the mounting plate (52), and through the cooperation of the vibrating spring (53), the filter element (7) vibrates left and right, thereby cleaning the abrasive particles adhering to the surface of the filter element (7) and improving the practicality of the device.

[0024] [Fig.3]-5 shows the second implementation method. The main difference from the first implementation method is that the mounting mechanism (6) comprises four threaded rods (61), which are fixedly connected to the inner wall of the mounting plate (52) at equal distances. The surface of the threaded rod (61) is threadedly connected to a threaded sleeve (62), and the threaded sleeve (62) penetrates the mounting plate (52) and extends toward the inside of the mounting slot (54). One end of the four threaded sleeves (62) located inside the mounting slot (54) is fixedly connected to an arc pressure plate (63). surfaces of the four threaded rods (61) are all fixedly connected to the driven gears (64). The top of the inner wall of the mounting plate (52) is slidably connected to the first annular gear (65) via an annular chute. The top of the first annular gear (65) is fixedly connected to the second annular gear (66). The second annular gear (66) meshes with the four driven gears (64) for transmission. The bottom of the inner wall of the mounting plate (52) located below is rotatably connected to a rotating rod (67). The rotating rod (67) penetrates the lower mounting plate (52) and the upper mounting plate (52), and extends above the upper mounting plate (52). The upper end of the threaded sleeve (62) located above the rotating rod (67) is fixedly connected to a rotating handle (69).The inner surface of the two mounting plates (52) located above and below the rotating rod (67) is fixedly connected to the driving gear (68). The upper driving gear (68) meshes with the first annular gear (65) located inside the upper mounting plate (52) for transmission. At the same time, the lower driving gear (68) meshes with the first annular gear (65) located inside the lower mounting plate (52) for transmission.

[0025] The filter element is installed inside the filter cylinder via a mounting mechanism, which makes the filter element stable and reliable after installation. In addition, the installation method is simple and quick, facilitating the removal and replacement of the filter element, thereby improving the convenience of using the device.

[0026] After the double-cylinder filter has been used for a certain period of time, the drive motor (55) is started, and the rotation of the drive motor 55 drives the cam (56) to rotate. The cam (56) rotates and contacts the mounting plate (52), thereby pushing the mounting plate (52) to move to the right. With the cooperation of the vibrating spring (53), the mounting plate (52) vibrates left and right, thereby driving the filter element (7) to vibrate left and right. Thus, the abrasive particles adhering to the surface of the filter element (7) are vibrated and cleaned. In addition, when it is necessary to replace the filter element (7), turn the rotating handle (69). The rotating handle (69) rotates and drives the upper and lower drive gears (68) to rotate through the rotating rod (67).The rotation of the driving gear (68) rotates the first annular gear (65), and the first annular gear (65) rotates the driven gear (64) through the second annular gear (66). The rotation of the driven gear (64) rotates the threaded rod (61). The threaded rod (61) rotates and moves the threaded sleeve (62), thereby causing the arc pressure plate (63) to move away from the filter element (7) side. Therefore, the filter element (7) can be disassembled. During installation, place the filter element (7) in the upper mounting slot (54) and ensure that the bottom of the filter element (7) . enters the lower mounting slot (54). Turn the rotary handle (69) to install and secure the filter element (7).

[0028] Although the examples of implementation of the utility model have been shown and described, it will be understood that ordinary technicians in this art can make various changes, modifications, substitutions and variations to these examples of implementation without departing from the principles and spirit of the utility model. The scope of the utility model is defined by the appended claims and their equivalents.
