Description

Technical Field

[0001] The utility model relates to the technical field of disc filters, in particular to a combined disc filter. Background Art

[0002] The disc filter is composed of a combination of filter units in parallel. The filter unit is mainly composed of a group of annular reinforced plastic filter discs with grooves or edges. The grooves between the upper and lower layers of discs play a role in filtering and intercepting. During filtration, sewage enters from the outside, and the discs are tightly compacted and stacked together in the unit. The rims formed by the groove edges on adjacent filter discs intercept solid matter in the water. During backwashing, water flows from the inside of the annular filter disc to the outside, flushing the dirt trapped on the filter disc and discharging it through the sewage outlet.

[0003] In the application document of a combined disc filter proposed with application number 202320099943.9, after the filter head body is inserted into the mounting seat, the screw is rotated to drive the rotating block to rotate inward through the threaded connection with the fixing frame. Under the connection limit of the connecting plate and the telescopic rod, the rotating block can push the connecting sleeve to translate inward, and through the connection of the connecting frame, drive the positioning sleeve to move inward, and press and fix it from the outside of the filter head body. At the same time, the plug-in block is inserted into it to further fix it. Similarly, when the filter head body needs to be removed from the water outlet main pipe, the above steps can be reversed. The combined disc filter has a reasonable structural design and is easy to use. The filter head is installed by a snap-on method. When it is damaged, it can be quickly removed, maintained or replaced. It has high practicality and also reduces the cost of use, which can fully meet the use needs.

[0004] Although the above application meets the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: after the water pipe is connected to the disc filter, the bolts are directly exposed to the outside, and the bolts are exposed to the outside for a long time, which is easy to come into contact with moisture in the air, which makes the bolts easy to rust, and then causes the bolts to rust later, making it difficult to disassemble the bolts.

[0032] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.

[0033] Embodiment: As Figures 1-5 shown, the present utility model provides a technical solution, a combined disc filter, including a water pipe 1. A plurality of filter head bodies 2 are evenly arranged on the top of the water pipe 1. A water inlet 5 is opened at the top of the filter head body 2. A closed protection assembly 3 is connected between the water pipe 1 and the filter head body 2. The closed protection assembly 3 includes a fixed cylinder 301, a movable cylinder 302, a fixed screw 303, a slider 304, a closing plate 305, a mounting screw 306 and a guide plate 307;

[0034] On the outer side of the water pipe 1, fixed cylinders 301 are evenly welded. Inside the fixed cylinder 301, a movable cylinder 302 is slidably connected. Inside the movable cylinder 302, a fixed screw 303 is connected by threads. The fixed screw 303 penetrates through the fixed cylinder 301 to facilitate the fixation of the movable cylinder 302. At both ends of the top of the movable cylinder 302, sliders 304 are welded. At the positions corresponding to the sliders 304 on the closing plate 305, chutes are provided. The longitudinal sections of the sliders 304 and the chutes are both T-shaped to avoid the problem of the closing plate 305 falling off. The outer side of the slider 304 is slidably connected with the closing plate 305. A rubber ring is adhered to the inner wall of the closing plate 305. The closing plate 305 is semi-circular, which is convenient for protecting the water pipe 1 and the filter head body 2 and makes the sealing performance between the closing plate 305 and the filter head body 2 better. The closing plate 305 and the slider 304 are connected by an installation screw 306. A guiding plate 307 is installed on the outer side of the closing plate 305 by screws. One end of the top of the guiding plate 307 is provided with an inclination angle to facilitate the guiding of water and prevent water from entering the inside of the fixed cylinder 301.

[0035] A connection sealing assembly 4 is installed on the top of the filter head body 2. The connection sealing assembly 4 includes a bidirectional threaded rod 401, clamping plates 402, limiting columns 403 and rubber plates 404.

[0036] One end of the top of the filter head body 2 is rotatably connected with a bidirectional threaded rod 401. The outer side of the bidirectional threaded rod 401 is connected with clamping plates 402 by threads. Inside one end of the clamping plate 402, a limiting column 403 is slidably connected. The limiting column 403 is fixedly installed on the top of the filter head body 2. The cross-section of the clamping plate 402 is arc-shaped to facilitate the limitation of the clamping plate 402 and ensure the stability of the movement of the clamping plate 402. A rubber plate 404 is adhered to one end of the clamping plate 402.

[0037] After the personnel install the filter head body 2 on the outer side of the water pipe 1, then the personnel pull the movable cylinder 302 to make the movable cylinder 302 move inside the fixed cylinder 301. After moving the movable cylinder 302 to a suitable position, then fix the movable cylinder 302 through the fixed screw 303. Then the personnel move the closing plate 305. After the closing plate 305 contacts the filter head body 2, fix the closing plate 305 through the installation screw 306. Thus, the connection position between the water pipe 1 and the filter head body 2 can be protected, preventing the bolts at the connection position from being directly exposed outside, causing the problem of bolt rusting and resulting in the problem that it is not convenient to disassemble the filter head body 2 later, and the connection position between the water pipe 1 and the filter head body 2 can be sealed.

[0038] Subsequently, after connecting the water inlet pipe to the water inlet 5 at the top of the filter head body 2, the operator rotates the bidirectional threaded rod 401 to drive the clamping plate 402 to move, so that the rubber plate 404 contacts the water inlet pipe and the filter head body 2, thereby performing secondary sealing on the connection part to prevent water leakage during the water inlet process.

[0039] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
