Description

Technical Field

[0001] This utility model relates to the field of sludge thickener technology, specifically to an anti-clogging filter module for a sludge thickener. Background Technology

[0002] Sludge thickeners are core equipment in wastewater treatment and industrial solid waste treatment. Their core function is to reduce the free water content in sludge through physical or mechanical means, thereby reducing sludge volume (typically by 50%-80%). This lays the foundation for subsequent sludge dewatering, transportation, or final disposal (such as landfill, incineration, or resource utilization). It significantly reduces energy consumption, reagent usage, and costs in subsequent treatment stages, making it a crucial link in the "volume reduction" process within sludge treatment systems.

[0003] The anti-clogging filter module of the sludge thickener is the "core functional unit" of the sludge thickener. Its core function is to eliminate the accumulation and clogging of solid particles, fibers, colloids and other substances on the filter element while realizing the solid-liquid separation of sludge. However, when filtering sludge, some sludge will accumulate on the screen plate, which can easily cause clogging. Utility Model Content

[0004] To solve the above technical problems, this utility model provides the following technical solution: an anti-clogging filter module for a sludge thickener, comprising:

[0005] A filter housing, wherein a mesh plate one is fixedly connected to the inner side of the filter housing, a bracket is fixedly connected to the inner side of the filter housing away from the mesh plate one, a mesh plate two is fixedly connected to the middle of the inner side of the filter housing, a guide vane is rotatably connected between the bracket and the mesh plate two, a cleaning component is rotatably connected to the side of the mesh plate one, and a contact component is rotatably connected between the mesh plate one and the mesh plate two.

[0006] The cleaning component includes a cleaning shaft, the side of which is rotatably connected to the inner side of the first mesh plate, and cleaning rods are fixedly connected to both sides of the cleaning shaft, with the sides of the cleaning rods contacting the sides of the first mesh plate.

[0007] The contact component includes a contact shaft, one end of which is fixedly connected to a cleaning shaft, and the other end of which is fixedly connected to the end of the guide vane away from the support. Slide rods are slidably connected to both sides of the contact shaft, and a scraper is fixedly connected to the other end of each slide rod. A first spring is sleeved on each slide rod, one end of which is fixedly connected to the scraper, and the other end of which is fixedly connected to the side of the contact shaft. A second slide rod is slidably connected to the side of the contact shaft away from slide rod one, and a dispersion plate is fixedly connected to the other end of each slide rod. A second spring is sleeved on each slide rod, one end of which is fixedly connected to the dispersion plate, and the other end of which is fixedly connected to the side of the contact shaft.

[0008] This utility model provides an anti-clogging filter module for a sludge thickener. It has the following beneficial effects:

[0009] 1. The anti-clogging filter module of this sludge thickener is equipped with a cleaning component to prevent sludge from accumulating on the screen plate and causing blockage. This ensures that the screen plate always maintains good filtration performance, ensures that the sewage filtration efficiency remains stable and does not decrease, avoids a sudden drop in processing capacity due to blockage, reduces the frequency of manual disassembly and cleaning of the screen plate, and reduces the workload and maintenance costs of operation and maintenance personnel.

[0010] 2. The anti-clogging filter module of this sludge thickener is equipped with contact components to prevent corrosion and scaling caused by long-term sludge adhesion to the inner side of the outer shell, and to reduce wear and tear on the outer shell caused by dirt erosion; and the elastic buffering effect of the first spring allows the scraper to adapt to slight differences in the flatness of the inner side of the outer shell, ensuring the cleaning effect while avoiding wear caused by hard friction between the scraper and the outer shell.

[0011] 3. The anti-clogging filter module of this sludge thickener is equipped with contact components. The elasticity of the second spring allows the slide bar to slide adaptively according to the magnitude of centrifugal force, i.e., changes in sewage flow. Regardless of fluctuations in sewage flow, the dispersion plate can maintain a reasonable range of movement, ensuring stable interception effect. Attached Figure Description

[0017] 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.

[0018] Example 1, please refer to Figures 1-2 This utility model provides a technical solution: an anti-clogging filter module for a sludge thickener, comprising:

[0019] A filter housing 1 has a mesh plate 2 fixedly connected to its inner side, a bracket 4 fixedly connected to the side of the inner side of the filter housing 1 away from the mesh plate 2, a mesh plate 5 fixedly connected to the middle of the inner side of the filter housing 1, a guide vane 3 rotatably connected between the bracket 4 and the mesh plate 5, a cleaning component 7 rotatably connected to the side of the mesh plate 2, and a contact component 6 rotatably connected between the mesh plate 2 and the mesh plate 5.

[0020] Please see Figure 3 The cleaning component 7 includes a cleaning shaft 71, the side of which is rotatably connected to the inner side of the screen plate 2, and cleaning rods 72 are fixedly connected to both sides of the cleaning shaft 71, with the side of the cleaning rods 72 in contact with the side of the screen plate 2.

[0021] When wastewater enters the filter housing 1, its impact force will cause the guide vanes 3 on the support 4 to rotate.

[0022] During this process, the guide vane 3 synchronously drives the cleaning shaft 71 to rotate in the area of ​​the screen plate 2 through the contact shaft 61, and the cleaning shaft 71 further drives the cleaning rods 72 on both sides. The cleaning rods 72 will continuously contact the side of the screen plate 2 to clean the sludge attached to the surface of the screen plate 2 in real time.

[0023] Please see Figure 4 The contact component 6 includes a contact shaft 61, one end of which is fixedly connected to the cleaning shaft 71, and the other end of which is fixedly connected to the end of the guide vane 3 away from the bracket 4. Both sides of the contact shaft 61 are slidably connected to a sliding rod 62, and the other end of the sliding rod 62 is fixedly connected to a scraper 63. A first spring 64 is sleeved on the sliding rod 62, one end of which is fixedly connected to the scraper 63, and the other end of which is fixedly connected to the side of the contact shaft 61. A second sliding rod 65 is slidably connected to the side of the contact shaft 61 away from the sliding rod 62, and the other end of the sliding rod 65 is fixedly connected to a dispersion plate 66. A second spring 67 is sleeved on the sliding rod 65, one end of which is fixedly connected to the dispersion plate 66, and the other end of which is fixedly connected to the side of the contact shaft 61.

[0024] When the sewage entering the filter housing 1 generates an impact force, it drives the guide vane 3 on the support 4 to rotate. During the rotation of the guide vane 3, centrifugal force is generated.

[0025] The centrifugal force will push the slide bar 62 to slide outward on the contact shaft 61, while stretching the first spring 64 sleeved on the slide bar 62. The slide bar 62 will then drive the scraper 63 to rotate synchronously with the inner side of the filter housing 1, thus avoiding the problem that a large amount of sludge will adhere to the inner side of the housing when the sewage flows through the filter housing 1 for a long time, thereby interfering with the sewage flow speed.

[0026] The scraper 63 cleans the sludge inside the outer shell in real time, preventing sludge from accumulating and forming an obstruction layer, ensuring that the wastewater can always pass through the filter shell 1 at a stable speed, and that the overall treatment capacity will not decrease due to the narrowing of the channel.

[0027] When the sewage entering the filter housing 1 generates an impact force, it drives the guide vane 3 on the support 4 to rotate. During the rotation of the guide vane 3, centrifugal force is generated.

[0028] The centrifugal force will push the second slide rod 65 to slide outward on the contact shaft 61, while stretching the second spring 67 sleeved on the second slide rod 65. The second slide rod 65 will then drive the dispersion plate 66 to move synchronously.

[0029] The evenly spaced horizontal grooves on the dispersion plate 66 can entangle and intercept filamentous impurities mixed in the sewage, such as fibers and hair.

[0030] By intercepting filamentous impurities in advance, it is possible to prevent them from tangling on core components such as mesh plates and pipes and forming blockages, thus avoiding narrowing of sewage flow channels, a sharp drop in filtration efficiency, and reducing the frequency of equipment downtime for cleaning due to impurity blockage.

[0031] The horizontal grooves on the dispersion plate 66 are evenly distributed, which can maximize the contact with filamentous impurities in the sewage and achieve higher entanglement and interception efficiency.

[0032] Specific workflow:

[0033] After the sewage pipe is connected to the filter housing 1, the sewage containing sludge enters the device. First, the sewage flows through the mesh plate 2, which intercepts and filters the sludge in the sewage. The filtered sewage then smoothly enters the filter housing 1.

[0034] As sewage continues to flow in, the resulting impact will drive the guide vane 3 to rotate between the support 4 and the mesh plate 5;

[0035] When the guide vane 3 rotates, it will simultaneously drive the contact component 6 to rotate inside the filter housing 1, intercepting and grabbing the filamentous impurities mixed in the sewage; on the other hand, it will drive the cleaning component 7 to rotate on the surface of the screen plate 2, so that the cleaning component 7 contacts the side of the screen plate 2, thereby completing the cleaning work of the screen plate 2 and preventing the screen plate 2 from being blocked by sludge accumulation.

[0036] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
