Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically an iron and manganese removal filter. Background Technology

[0002] Chinese Patent Publication No. CN208345878U discloses an iron and manganese removal filter, including a housing and supporting feet on both sides of the bottom of the housing. The housing has a top cover, and a motor is installed in the middle of the top cover. The output end of the motor is connected to a stirring device, which is connected to the top cover via a bearing and extends into the housing. A first water inlet and a second water inlet are distributed on the left and right sides of the top cover. An exhaust pipe is connected to one side of the upper part of the outer wall of the housing. This utility model of an iron and manganese removal filter has a novel structure and is easy to operate. Wastewater can be easily added into the housing through the first water inlet. Then, the stirring device is rotated by the motor. The stirring device has a semi-arc stirring branch, and the outer wall of the semi-arc stirring branch is adhered with an activated carbon filter layer. Therefore, the activated carbon filter layer can be used to perform preliminary filtration and deodorization of wastewater.

[0003] In actual use, the artificial manganese sand and quartz sand filter layers are fixed inside the housing by pressure bars. This makes it inconvenient to clean the artificial manganese sand and quartz sand filter layers daily. Moreover, the fixing of the pressure bars will cause leakage of the artificial manganese sand and quartz sand filter layers, resulting in the loss of the artificial manganese sand and quartz sand filter layers, reducing the filtration effect on sewage, and is not conducive to long-term sewage filtration. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: an iron and manganese sand filter, comprising a filter cylinder, a support, and a top cover. The support is fixedly connected to the bottom of the filter cylinder, and the top cover is threadedly connected to the top of the filter cylinder. A servo motor is fixedly connected to the top of the top cover. The output end of the servo motor passes through the inner wall of the top cover and is fixedly connected to a rotating shaft. A scraper is fixedly connected to the bottom of the rotating shaft. A groove is formed on the inner wall of the filter cylinder. An activated carbon filter layer is provided on the inner side of the filter cylinder. A filter assembly is provided on the inner side of the filter cylinder below the activated carbon filter layer.

[0005] As a further embodiment of this utility model, an air outlet is fixedly provided on the top of the top cover, a liquid inlet is fixedly provided on the top of the top cover, and a liquid outlet is fixedly provided on the bottom of the filter cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. During operation, the threaded connection between the filter frame and the filter screen facilitates daily cleaning of the artificial manganese sand and quartz sand filter layers. The filter frame is also fixed and stable, preventing leakage of the artificial manganese sand and quartz sand filter layers. This avoids the loss of the artificial manganese sand and quartz sand filter layers, improves the filtration effect of sewage, and is conducive to long-term sewage filtration operation.

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Implementation examples, by Figure 1-5 The present invention includes a filter cylinder 1, a support 2, and a top cover 3. The support 2 is fixedly connected to the bottom of the filter cylinder 1, and the top cover 3 is threadedly connected to the top of the filter cylinder 1. A servo motor 4 is fixedly connected to the top of the top cover 3. The output end of the servo motor 4 passes through the inner wall of the top cover 3 and is fixedly connected to a rotating shaft 8. A scraper 9 is fixedly connected to the bottom of the rotating shaft 8. A groove 10 is formed in the inner wall of the filter cylinder 1. An activated carbon filter layer 11 is provided on the inner side of the filter cylinder 1. A connecting block that matches the size of the groove 10 is fixedly connected to the outer side of the activated carbon filter layer 11. The connecting block is located inside the groove 10. A threaded rod 14 is inserted into the inner side of the groove 10. A rubber block 13 is fixedly connected to the top of the threaded rod 14.

[0022] A filter assembly 12 is provided on the inner side of the filter cylinder 1 below the activated carbon filter layer 11. The filter assembly 12 includes a filter frame 121, a slider 122, and a filter screen 123. The filter frame 121 is slidably connected to the inner side of the filter cylinder 1, and the slider 122 is fixedly connected to the outer side of the filter frame 121 inside the groove 10. The filter screen 123 is threadedly connected to the inner side of the filter frame 121. The threaded connection between the filter frame 121 and the filter screen 123 facilitates daily cleaning of the artificial manganese sand and quartz sand filter layers.

[0023] An air outlet 5 is fixedly provided on the top of the top cover 3, an inlet 6 is fixedly provided on the top of the top cover 3, an outlet 7 is fixedly provided on the bottom of the filter cylinder 1, a threaded rod 14 passes through the inner wall of the connecting block and is threadedly connected to the connecting block, a threaded rod 14 passes through the inner wall of the slider 122 and is threadedly connected to the slider 122, and the threaded rod 14 extends to the bottom of the groove 10.

[0024] Working principle: During operation, wastewater is injected into the inside of the filter cylinder 1 through the inlet 6. The wastewater is initially filtered and deodorized by the activated carbon filter layer 11, thereby blocking foreign objects above the activated carbon filter layer 11. At the same time, the odor generated by the wastewater can be discharged from the outlet 5. Meanwhile, the rotation of the rotating shaft 8 is driven by the servo motor 4, which enables the scraper 9 to clean the area above the activated carbon filter layer 11, preventing foreign objects from blocking the filter holes of the activated carbon filter layer 11 and ensuring that the wastewater can pass through the activated carbon filter layer 11 normally, thus preventing the activated carbon filter layer 11 from becoming clogged.

[0025] Subsequently, the wastewater will pass through the filter assembly 12. Quartz sand can be placed inside the upper filter frame 121 and connected through the filter screen 123. Artificial manganese sand can be placed inside the lower filter frame 121 for filtration, thereby achieving the removal of iron and manganese from the wastewater. The specific working principle has been disclosed in the document with publication number CN208345878U.

[0026] During routine maintenance, the top cover 3 can be removed, and the rubber block 13 can be pulled to move the threaded rod 14 upward, thereby pulling the connecting block outside the activated carbon filter layer 11 upward along the groove 10. The slider 122 will also move upward along the inner side of the groove 10, thus removing the activated carbon filter layer 11 and the filter assembly 12 for easy cleaning. At the same time, the threaded connection between the filter frame 121 and the filter screen 123 facilitates daily cleaning of the artificial manganese sand and quartz sand filter layers. The filter frame 121 is fixed and stable, preventing leakage of the artificial manganese sand and quartz sand filter layers, thus avoiding the loss of the artificial manganese sand and quartz sand filter layers, improving the filtration effect of sewage, and benefiting the long-term operation of sewage filtration.
