Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology, and in particular to a Y-type filter. Background Technology
[0002] Y-type filters are an indispensable filtration device in pipeline systems that transport media. They are typically installed at the inlet of pressure reducing valves, pressure relief valves, level control valves, or other equipment to remove impurities from the media and protect the valves and equipment from damage.
[0003] A search revealed a Chinese patent publication number CN221889342U, which discloses a Y-type filter, including a valve body and a brush shaped to match the filter cartridge. The valve body has an inlet channel and an outlet channel, with a filter chamber between the outlet channel and the inlet channel. The filter cartridge is housed within the filter chamber, and the valve body is covered with a valve cover to seal the filter chamber. The brush is slidably disposed within the filter cartridge, and the valve body has a sliding device for driving the brush to slide. This patent utilizes the reciprocating sliding of the brush within the filter cartridge to clean the inner wall of the filter cartridge, preventing impurities from clogging it. However, the brush will wear down after sliding back and forth for a long time. After the brush wears down, it will be difficult for it to contact the inner wall of the filter cartridge, which will affect the cleaning effect. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a Y-type filter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A Y-type filter includes a valve body with an inlet channel and an outlet channel. A filter chamber is provided between the inlet and outlet channels. A filter cylinder is fixedly positioned on the inner wall of the filter chamber. A cleaning assembly is provided inside the filter chamber, which contacts the inner wall of the filter cylinder. The cleaning assembly includes a central block and multiple guide cylinders. The central block is coaxially arranged with the filter cylinder. The multiple guide cylinders are fixedly connected to the outer wall of the central block. A connecting rod is slidably connected to the inner wall of the guide cylinder. One end of the connecting rod is fixedly connected to a sliding block that slides with the inner wall of the guide cylinder. The other end of the connecting rod is detachably fixedly connected to a brush. A compensating spring is provided inside the guide cylinder, and both ends of the compensating spring are connected to the guide cylinder and the sliding block, respectively.
[0006] As a further embodiment of this utility model: the multiple guide cylinders are divided into two groups arranged in a straight line along the axis of the central block, and the guide cylinders in each group are arranged circumferentially around the axis of the central block, with the two groups of guide cylinders being staggered.
[0007] As a further improvement of this utility model, a valve cover is fixedly positioned on the inner wall of the filter chamber.
[0008] As a further improvement of this utility model: the brush is arc-shaped and partially overlaps with the brush connected to the internal connecting rods of the two sets of guide cylinders; a drive component for moving the cleaning assembly is provided on the outside of the valve body.
[0009] As a further embodiment of this utility model: the driving assembly includes a pulling rod and an electric telescopic rod, the pulling rod is coaxial with the filter cylinder, and the pulling rod is slidably engaged with the valve cover.
[0010] As a further embodiment of this utility model: one end of the pulling rod is fixedly connected to the center block, and the other end of the pulling rod is fixedly connected to a connecting plate.
[0011] As a further embodiment of this utility model: the electric telescopic rod is fixedly installed on the outer wall of the valve body, and the connecting plate is fixedly connected to the telescopic end of the electric telescopic rod.
[0012] Compared with the prior art, the present invention provides a Y-type filter, which has the following beneficial effects: 1. This utility model, by providing a cleaning component, can push the brush to move to compensate after the brush wears down, thus ensuring the cleaning effect.
[0013] 2. In this utility model, by setting the guide cylinder to two sets and having multiple brushes partially overlapping, the multiple brushes can still completely cover the filter cylinder after compensation, and no cleaning dead corners will be formed after compensation.
[0014] 3. This utility model, by providing a driving component that is rigidly connected to the central block, makes the movement of the central block more stable and reliable compared to existing structures, avoiding problems such as wear and jamming in the spring-rope structure.
[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0020] Example 1: A Y-type filter, such as Figures 1 to 4 As shown, the device includes a valve body 1, which has an inlet channel 2 and an outlet channel 3. A filter chamber 4 is provided between the inlet channel 2 and the outlet channel 3. A valve cover 6 is fixed to the inner wall of the filter chamber 4. A filter cylinder 5 for sealing the filter chamber 4 is threaded onto the valve body 1. A cleaning component 8 that contacts the inner wall of the filter cylinder 5 is provided inside the filter chamber 4.
[0021] The cleaning assembly 8 includes a central block 9 and multiple guide cylinders 10. The central block 9 is coaxially arranged with the filter cylinder 5. The multiple guide cylinders 10 are all fixedly connected to the outer wall of the central block 9. The multiple guide cylinders 10 are divided into two groups arranged in a straight line along the axis of the central block 9. The guide cylinders 10 in each group are arranged circumferentially around the axis of the central block 9. The two groups of guide cylinders 10 are staggered. A connecting rod 11 is slidably connected to the inner wall of the guide cylinder 10. One end of the connecting rod 11 is fixedly connected to a sliding block 14 that slides with the inner wall of the guide cylinder 10. The other end of the connecting rod 11 is detachably fixedly connected to a brush 12. A compensating spring 13 is provided inside the guide cylinder 10. The two ends of the compensating spring 13 are respectively connected to the guide cylinder 10 and the sliding block 14.
[0022] The brush 12 is arc-shaped and partially overlaps with the brush 12 connected to the internal connecting rod 11 of the two sets of guide cylinders 10. A drive component for moving the cleaning assembly 8 is provided on the outside of the valve body 1, and a controller electrically connected to the drive component is provided on the outside of the valve body 1.
[0023] During cleaning, the drive component drives the cleaning component 8 to move linearly along the axis of the filter cylinder 5, and cleans the filter cylinder 5 through the brush 12. When the brush 12 is worn, the compensation spring 13 pushes the sliding block 14 to move on the inner wall of the guide cylinder 10, pushing the brush 12 away from the axis of the center block 9 to compensate for the wear. Since the guide cylinder 10 consists of two sets of staggered arrangement and there is an overlap between the multiple brushes 12, the multiple brushes 12 can still completely cover the filter cylinder 5 after compensation, and no cleaning dead corner will be formed after compensation.
[0024] By incorporating a cleaning component 8, the brush 12 can be moved to compensate for wear and tear, ensuring effective cleaning.
[0025] By setting the guide cylinder 10 into two sets with multiple brushes 12 partially overlapping, the multiple brushes 12 can still completely cover the filter cylinder 5 after compensation, and no cleaning dead corners will be formed after compensation.
[0026] Example 2: A Y-type filter. This example is based on Example 1, with the following improvements: Figure 1 , Figure 2 As shown, the drive assembly includes a pull rod 7 and an electric telescopic rod 15. The pull rod 7 is coaxial with the filter cartridge 5 and slides with the valve cover 6. The valve cover 6 has a dynamic sealing structure for sealing inside. The dynamic sealing structure is a mature existing technology, and its basic structure and working principle are well known to those skilled in the art, so it will not be described in detail here. One end of the pull rod 7 is fixedly connected to the center block 9, and the other end of the pull rod 7 is fixedly connected to a connecting plate 16. The electric telescopic rod 15 is fixedly installed on the outer wall of the valve body 1, and the connecting plate 16 is fixedly connected to the telescopic end of the electric telescopic rod 15.
[0027] During cleaning, the electric telescopic rod 15 drives the connecting plate 16 to move back and forth, and the connecting plate 16 drives the center block 9 to move through the pull rod 7 for cleaning.
[0028] By incorporating a drive component that is rigidly connected to the center block 9, the movement of the center block 9 is more stable and reliable compared to existing structures, avoiding problems such as wear and jamming in the spring-rope structure.
[0029] Working principle: The electric telescopic rod 15 drives the connecting plate 16 to move back and forth. The connecting plate 16 drives the cleaning component 8 to move linearly along the axis of the filter cylinder 5 through the pull rod 7. The filter cylinder 5 is cleaned by the brush 12. When the brush 12 is worn, the compensation spring 13 pushes the sliding block 14 to move on the inner wall of the guide cylinder 10, pushing the brush 12 away from the axis of the center block 9 to compensate for the wear. Since the guide cylinder 10 is set in two sets with staggered arrangement and there is an overlap between the multiple brushes 12, the multiple brushes 12 can still completely cover the filter cylinder 5 after compensation, and no cleaning dead corner will be formed after compensation.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
