[0002] High-mineralized wastewater (such as wastewater generated by chemical, metallurgical, and mining industries) contains a large amount of dissolved solids and suspended matter. Direct discharge can lead to environmental problems such as water pollution and soil salinization. Therefore, it generally needs to be treated before being discharged.

[0003] Existing filtration devices are often used in the treatment of high-mineralized wastewater. However, these devices typically employ fixed filter screens, which allow impurities in the wastewater to accumulate on the screen surface, forming a filter cake. This leads to increased filtration resistance, decreased flow rate, and frequent clogging. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed.

Therefore, they should not be construed as limitations on this utility model.

[0020] This embodiment discloses a filtration device for treating high-mineralization wastewater that prevents clogging. Through the coordinated arrangement of the rotating shaft 3, the filter cylinder 6, and the drive mechanism 4, the filter cylinder 6 can rotate, thereby moving impurities and effectively avoiding the clogging problem of traditional static filtration devices. (Refer to...) Figures 1-6It mainly includes a support frame 1, a housing 2, and a water outlet pipe 201. The housing 2 is fixedly installed on the support frame 1, and the water outlet pipe 201 is installed at the lower end of the housing 2. The feature is that: a rotating shaft 3 is rotatably installed on one side of the housing 2, and a filter cylinder 6 for filtering wastewater is fixedly connected to the rotating shaft 3 located inside the housing 2. A drive mechanism 4 for driving the rotating shaft 3 is installed on the outer wall of the housing 2. A mounting frame 7 is fixedly connected to the inner side of the housing 2, and a cleaning brush 8 for cleaning the filter cylinder 6 is detachably installed on the mounting frame 7 through a snap-fit ​​component 9. Through the cooperative design of the cleaning brush 8, the filter cylinder 6 can be cleaned in real time, further effectively preventing impurities from clogging the filter cylinder 6 and affecting the filtration effect. Through the ingenious design of the snap-fit ​​component 9, it is easy to install and remove the cleaning brush 8, thereby facilitating the regular replacement and maintenance of the cleaning brush 8.

[0021] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3 The drive mechanism 4 includes a driven gear 401, a driving gear 402, and a motor 403. The motor 403 is fixedly mounted on the outer wall of the housing 2. The output shaft of the motor 403 is fixedly connected to the driving gear 402. The driven gear 401, which meshes with the driving gear 402, is fixedly mounted on the rotating shaft 3. In actual use, the motor 403 is started, and the motor 403 drives the driving gear 402 to rotate. The driving gear 402 meshes with the driven gear 401, causing the driven gear 401 to rotate. The driven gear 401 drives the rotating shaft 3 to rotate.

[0022] In this embodiment, refer to Figure 1 and Figure 3 The diameter of the driven gear 401 is larger than that of the driving gear 402; this can create a speed reduction and torque increase effect, ensuring that the filter cartridge 6 operates stably at low speeds, while reducing the load on the motor 403 and lowering energy consumption.

[0023] In this embodiment, refer to Figure 2 , Figure 4 , Figure 5 and Figure 6The snap-fit ​​assembly 9 includes a rectangular plate 901, a mounting hole 902, a sliding shaft 903, a sliding plate 904, a spring 905, and an opening 906. The mounting hole 902 is located on one side of the rectangular plate 901, and the interior of the mounting hole 902 is fixedly connected to one end of the spring 905. The other end of the spring 905 is fixedly connected to the sliding plate 904. The sliding shaft 903 is fixedly connected to the side of the sliding plate 904 away from the spring 905. The sliding shaft 903 is coaxially arranged with the mounting hole 902. The upper end of the rectangular plate 901 has an opening 906 that allows the sliding plate 904 to move left and right. Several cleaning brushes 8 are present, and each cleaning brush 8 has a snap-fit ​​assembly 9 installed in the middle of its upper end. The mounting bracket 7 has several rectangular openings that fit the rectangular plate 901 in the snap-fit ​​assembly 9. When it is necessary to move the cleaning brush 8... During installation, the sliding plate 904 is moved, causing the sliding shaft 903 to move until it enters the mounting hole 902. At this point, the rectangular plate 901 is positioned within the rectangular opening. Then, the sliding plate 904 is released, and the sliding shaft 903 is reset under the force of the spring 905, placing it at the upper end of the mounting bracket 7 to prevent the rectangular plate 901 from moving downwards. Through the limiting of the rectangular plate 901 and the rectangular opening, as well as the blocking effect of the sliding shaft 903, the cleaning brush 8 can be installed on the mounting bracket 7. When it is necessary to remove the cleaning brush 8, the sliding plate 904 is moved, causing the sliding shaft 903 to move until the rectangular plate 901 moves downwards without interference. At this point, the cleaning brush 8 can be easily and quickly removed from the mounting bracket 7.

[0024] In this embodiment, a first magnet 907 is fixedly sleeved at the end of the sliding shaft 903 away from the sliding plate 904, and a second magnet that can attract the first magnet 907 is fixedly connected to the upper end of the mounting frame 7; by setting the first magnet 907 and the second magnet, the firmness of the cleaning brush 8 installed on the mounting frame 7 can be further improved.

[0025] In this embodiment, refer to Figure 4 , Figure 5 and Figure 6 The lower end of the sliding shaft 903 abuts against the upper end of the mounting bracket 7; this effectively prevents the rectangular plate 901 from moving downwards, further improving the stability of the cleaning brush 8 installation.

[0026] In this embodiment, refer to Figure 2 The filter cartridge 6 has a sealing plate that is detachably installed at the end away from the rotating shaft 3 by bolts; the detachable design of the sealing plate makes it easy to clean the impurities inside the filter cartridge 6 regularly.

[0027] In this embodiment, refer to Figure 1 , Figure 2 and Figure 3The middle of the sealing plate is rotatably connected to the water inlet pipe 5 (a valve is installed on the water inlet pipe 5, not shown in the figure). The water inlet pipe 5, located outside the filter cylinder 6, passes through the housing 2 and extends to the outside of the housing 2. The water inlet pipe 5 facilitates the flow of wastewater into the filter cylinder 6.

[0028] The working principle of this anti-clogging high-mineralization wastewater treatment filtration device is as follows: When wastewater needs to be filtered, the wastewater is introduced into the filter cylinder 6 through the inlet pipe 5. After the inlet is complete, the motor 403 is started, which drives the drive gear 402 to rotate. The drive gear 402 meshes with the driven gear 401, causing the driven gear 401 to rotate. The driven gear 401 drives the rotating shaft 3 to rotate, thereby causing the filter cylinder 6 to rotate, thus filtering the wastewater. The filtered water flows to the lower end of the housing 2 and finally flows out from the outlet pipe 201. During the rotation of the filter cylinder 6, the cleaning brush 8 can clean the filter cylinder 6 in real time, further reducing the clogging of the filter cylinder 6.
