Abstract
Description
Technical Field
[0001] This utility model belongs to the field of filter technology, specifically relating to a fiber ball filter that is easy to replace. Background Technology
[0002] A fiber ball filter consists of a bed of fiber balls packed into a container. Because the individual fiber balls are relatively loosely spaced, their fibers can interweave within the bed, rendering the individual characteristics of the fiber balls insignificant and creating a unified filter bed. The pressure exerted on the fiber balls in the bed is the sum of the fluid resistance of the filtered water flow, the weight of the fiber balls themselves, and the weight of the trapped loose matter (if the water flows from top to bottom through the bed, this force increases sequentially along the flow direction within the filter layer).
[0003] Currently, most fiber ball filters have a single, integrated filtration structure, making it impossible to replace individual filter components. Furthermore, the filter structure cannot be lifted, making installation and replacement extremely inconvenient and difficult. Therefore, we propose a fiber ball filter that is easy to replace. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-2 This utility model provides a technical solution: an easy-to-replace fiber ball filter, including a housing 7, and a filter mechanism 1 is provided inside the housing 7; the filter mechanism 1 includes an upper filter section 11, a middle filter section 13 and a lower filter section 15, the upper filter section 11 is connected to the middle filter section 13 through an upper connecting rod 12, the middle filter section 13 is connected to the lower filter section 15 through a lower connecting rod 14, and the filter structures in the upper filter section 11, the middle filter section 13 and the lower filter section 15 can be replaced independently. Since there are gaps between the upper filter section 11, the middle filter section 13 and the lower filter section 15, the filter structures of the upper filter section 11, the middle filter section 13 and the lower filter section 15 can be replaced.
[0017] Furthermore, a lower flange 5 is provided at the end of the outer casing 7, which is connected to the upper flange 4. A top cover 3 is also provided on the upper flange 4 to facilitate the disassembly and assembly of the top cover 3.

The positioning plate 112 is provided with a positioning hole, and a positioning screw 114 is provided in the positioning hole. The positioning screw 114 is located at the bottom of the filter screen 111. A locking nut 113 is also provided on the positioning screw 114, which allows the filter screen 111 to be disassembled and installed, making it easy to replace the filter screen 111. When replacing the filter screen 111, loosen the locking nut 113 and pull the filter screen 111. The filter screen 111 separates the positioning screw 114 from the positioning plate 112. Then, insert the positioning screw 114 on the new filter screen 111 into the positioning hole and tighten the locking nut 113 to complete the replacement of the filter screen 111.
[0020] Furthermore, a flow guide shroud 115 is also provided inside the positioning disk 112. The central axis of the flow guide shroud 115 coincides with the central axis of the central filter section 13, which can concentrate and transport water to the central filter section 13 for further filtration.
[0021] Please see Figure 5 A detachable outer mounting sleeve 134 is provided inside the middle filter section 13. A fiber ball filter 131 is provided inside the outer mounting sleeve 134. A positioning block 133 is provided on the outer surface of the outer mounting sleeve 134. One end of the positioning block 133 is engaged in the positioning slot 132. The positioning slot 132 is located on both sides of the inner wall of the middle filter section 13, which allows the fiber ball filter 131 to be disassembled and replaced. Pushing the outer mounting sleeve 134 causes the positioning block 133 to move within the positioning slot 132. When the positioning block 133 moves out of the positioning slot 132, the fiber ball filter 131 is disassembled, and then a brand new fiber ball filter 131 is installed in the outer mounting sleeve 134. The positioning block 133 is then engaged in the positioning slot 132.
[0022] The lower mounting section of this application can be equipped with a filter element structure, and its overall replacement structure is the same as that of the middle filtration section 13.
[0023] Please see Figure 2 as well as Figure 3A lifting mechanism is also provided on one side of the outer casing 7 to control the synchronous lifting of the upper filter section 11, the middle filter section 13, and the lower filter section 15.

The ball screw pair 103 is connected to the lower filter section 15 and can synchronously lift the lower filter section 15, the middle filter section 13, and the upper filter section 11, which facilitates the replacement of the filter structure inside. A drive motor 106 is also provided on one side of the outer casing 7. A drive bevel gear 107 is provided at one end of the output shaft of the drive motor 106. The drive bevel gear 107 meshes with a driven bevel gear 108. The driven bevel gear 108 is located on one side of the longitudinal screw and can control the rotation direction of the ball screw, thereby controlling the lifting height of the lower filter section 15, the middle filter section 13, and the upper filter section 11.
[0024] When it is necessary to replace the filter structure in the upper filter section 11, the middle filter section 13, or the lower filter section, the top cover 3 is removed. The drive motor 106 drives the drive bevel gear 107 to rotate, the drive bevel gear 107 drives the driven bevel gear 108 to rotate, the driven bevel gear 108 drives the longitudinal lead screw 101 to rotate, the ball screw pair 103 drives the lower filter section 15 to move, the lower filter section 15 drives the middle filter section 13 to move through the lower connecting rod 14, the middle filter section 13 drives the upper filter section 11 to move through the upper connecting rod 12, and the upper filter section 11, the middle filter section 13, and the lower filter section 15 are moved out of the outer casing 7, making it convenient to replace the filter structure inside.
[0025] Furthermore, a limiting slider 104 is also provided on the lower filter section 15. One end of the limiting slider 104 is slidably disposed in the limiting groove 105. The limiting groove 105 is disposed on one side of the inner wall of the outer shell 7.
