Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sewage treatment device. Background Art

[0002] Chinese patent application number 202320719304.8 discloses a multi-stage sewage treatment device. The solution mainly includes a filter box with a filter chamber, and a filter material arranged in the filter chamber. The left and right sides of the filter box are provided with an inlet overflow channel and an outlet overflow channel connected to the filter chamber, and the bottom of the filter box is provided with a slag discharge switch channel connected to the filter chamber. When in use, the sewage enters the upper end of the filter chamber through the inlet overflow channel, and then passes through the filter material from top to bottom, and then overflows from the outlet overflow channel. By using such an overflow superimposed filtration method, the filtering effect of sewage can be enhanced, but in actual use, it still has the following shortcomings:

[0003] First, due to the overflow superposition filtration method, the filtered impurities are accumulated on the filter material from top to bottom. If there are too many accumulated impurities, it will cause blockage, resulting in the sewage flow rate slowing down or even being unable to flow. At this time, workers are required to open the filter box and use tools to dig out the impurities on the upper layer of the filter material. Then, by stirring the filter material, the impurities accumulated in the middle and lower layers of the filter material are dispersed to play a role in unblocking. Such a cleaning and maintenance process is very cumbersome, inefficient, and the labor intensity of workers is also high.

[0004] Secondly, since the lower end of the filter is directly set at the bottom of the filter chamber, the impurities accumulated in the middle and lower layers of the filter will be blocked by the filter when flowing to the slag discharge switch channel, so that these impurities are not effectively removed, and soon it will cause blockage again.

[0005] Therefore, in view of the above-mentioned deficiencies of the above-mentioned sewage treatment device, it is very necessary to further improve its structure in order to better meet people's application needs. Utility Model Content

The sewage treatment device is provided with a stirring mechanism and a sedimentation space in the filter chamber, so that under the stirring of the stirring mechanism, impurities accumulated in the upper, middle and lower layers of the filter can be settled in the sedimentation space, and then by opening the slag discharge switch channel, these impurities can flow to the slag discharge switch channel quickly, effectively and unobstructed, and be discharged away, thereby playing the role of dredging and preventing blockage; moreover, there is no need for workers to manually stir the filter, which is more efficient and can also reduce the labor intensity of workers.

[0021] like Figure 1As shown, the sewage treatment device with filtering and dredging functions described in the present invention includes a filter box 1 with a filter chamber 11, and a filter 2 arranged in the filter chamber 11, wherein the filter 2 is a granular, lightweight, porous adsorption ball. The filter box 1 is provided with an inlet overflow channel 101, a slag discharge switch channel 102, and an outlet overflow channel 103 connected to the filter chamber 11. In order to achieve the purpose proposed by the present invention, the filter chamber 11 is further provided with a partitioning mesh plate 3 that separates its cavity bottom from the filter 2, so as to form a sedimentation space 111 between the partitioning mesh plate 3 and the cavity bottom of the filter chamber 11, and the sedimentation space 111 is connected to the slag discharge switch channel 102; the filter chamber 11 is also provided with a stirring mechanism 4 for stirring and dredging the filter 2. The utility model provides a stirring mechanism 4 and a sedimentation space 111 in the filter chamber 11. When the sedimentation space 111 is full of water, the stirring mechanism 4 is started to stir, so that impurities accumulated in the gaps between the filtered objects 2 are settled to the bottom of the sedimentation space. Then, by opening the slag discharge switch channel 102, these impurities can flow to the slag discharge switch channel 102 quickly, effectively and unimpeded and be discharged, thereby playing the role of unblocking and preventing blockage. In addition, there is no need for workers to manually stir the filtered objects 2, which is more efficient and can also reduce the labor intensity of workers.

[0022] In order to ensure that the separation mesh plate 3 can be stably installed in the filter chamber 11, Figure 1 As shown, a mounting step 112 is provided on the wall of the filter chamber 11, and the partition mesh plate 3 is mounted on the mounting step 112. In this way, the partition mesh plate 3 can be stably mounted in the filter chamber 11, is not easy to collapse, and is also very convenient to install and remove.

[0023] In order to further improve the structure of the separation mesh 3, make it simple, scientific and reasonable, and easy to produce, Figure 2 As shown, the partitioning mesh panel 3 is composed of a mesh panel portion 31 and a frame portion 32 arranged around the sides of the mesh panel portion 31. The arrangement of the mesh panel portion 31 ensures that sewage and accumulated impurities can pass through the mesh panel portion 31 before being deposited into the settling space 111. The arrangement of the frame portion 32 enhances the structural strength of the sides of the mesh panel portion 31 and the entire structure, making it less prone to deformation and thus allowing the partitioning mesh panel 3 to be stably mounted on the mounting step 112.

[0024] In order to further increase the structural strength of the mesh portion 31, as Figure 1 As shown, the middle portion of the mesh plate portion 31 is further provided with a support portion 33 extending downward to the bottom of the sedimentation space 111. This can support the middle portion of the mesh plate portion 31 to enhance the structural strength of the middle portion of the mesh plate portion 31, so that the mesh plate portion 31 will not deform or collapse when the filtered material 2 is stirred.

[0025] In order to further improve the structure of the stirring mechanism 4, as Figure 3 As shown, the stirring mechanism 4 includes a motor 41, a connecting rod 42, and a stirring paddle 43. The motor 41 is arranged on the filter box 1, and the stirring paddle 43 is arranged in the filter chamber 11, and the stirring paddle 43 is driven and connected to the motor 41 through the connecting rod 42. Specifically, the motor 41 is arranged on the top surface of the filter box 1, and the upper end of the connecting rod 42 passes through the outside of the filter box 1 and is connected to the power output end of the motor 41. This can prevent the motor 41 from being damaged by moisture and increase the service life of the motor 41. The motor 41 is connected to a reduction gear box, and the connecting rod 42 is directly connected to the output end of the reduction gear box to reduce the speed output to the connecting rod 42, increase the torque, and increase the stirring force, so that the filter 2 can roll over and shake off the dirt and debris accumulated on its surface.

[0026] In order to prevent the connecting rod 42 from swinging left and right during stirring of the stirring blade 43 and to prevent the connecting rod 42 from breaking, Figure 2 As shown, the partitioning mesh plate 3 is further provided with a positioning seat 34 with a positioning groove 341, and the lower end of the connecting rod 42 can be rotatably inserted into the positioning groove 341. This can not only limit the position of the lower end of the connecting rod 42 to prevent it from swinging freely and breaking, but also does not affect the rotation and stirring of the connecting rod 42 and the stirring paddle 43, ensuring the normal use of the stirring mechanism 4.

[0027] In order to facilitate the maintenance of the stirring mechanism 4, Figure 3 As shown, a detachable insertion protrusion 44 and an insertion slot 45 are provided between the upper end of the connecting rod 42 and the power output end of the motor 41. The insertion slot 45 is provided with an anti-rotation limit protrusion 451, and the insertion protrusion 44 is also provided with an anti-rotation limit slot 441 that cooperates with the anti-rotation limit protrusion 451. This detachable structure allows the motor 41 and connecting rod 42 to separate when the filter box 1 is opened, preventing the stirring paddle 43 from being removed and causing some of the filtered material 2 to fall to the ground. The provision of the anti-rotation limit protrusion 451 and the anti-rotation limit slot 441 prevents the insertion protrusion 44 and the insertion slot 45 from spinning or idling after they are inserted together, ensuring that the motor 41 can drive the connecting rod 42 and the stirring paddle 43 to rotate, ensuring reliable operation. Specifically, the insertion slot 45 is located at the power output end of the motor 41, and the insertion protrusion 44 is located at the upper end of the connecting rod 42. Of course, the positions of the insertion groove 45 and the insertion protrusion 44 can also be interchanged.

[0028] In order to deodorize and sterilize the sedimentation space 111, the filter chamber 11, the filter 2 and the sewage during the filtering and cleaning process, Figure 1As shown, the filter box 1 is also equipped with an ozone input pipe connector 5 that extends through the sedimentation space 111. Connected to an ozone generator via the ozone input pipe connector 5, ozone gas can be directly delivered to the sewage in the sedimentation space 111 to kill bacteria, viruses, and other microorganisms in the sewage. This prevents ozone gas from reacting with substances in the sewage and, consequently, from producing malodorous gases, achieving the purpose of sterilization and deodorization. As the ozone gas moves upward, it deodorizes and sterilizes the sedimentation space 111, the filter chamber 11, the filtered material 2, and the sewage. This direct deodorization and sterilization of the sewage is more direct and effective.

[0029] To prevent sewage backflow, Figure 1 As shown, the ozone input pipe joint 5 is also connected in series with a one-way valve to prevent water from flowing back into the ozone machine.

[0030] In order to achieve a better cleaning effect on the filter 2, Figure 1 As shown, the upper end of the filter box 1 is also provided with a clean water inlet pipe connection port 6 that extends through the filter chamber 11. Specifically, the clean water inlet pipe connection port 6 extends from the top of the filter box 1 into the filter chamber 11. During cleaning, clean water is introduced through the clean water inlet pipe connection port 6 to flush the filter chamber 11 and the filtered material 2, thereby more effectively rinsing and removing impurities accumulated in the filtered material 2, thereby achieving a better cleaning effect on the filtered material 2.

[0031] To prevent the upper portion of the filtered material 2 from falling out of the filter chamber 11 during agitation, a clearance space 113 is formed between the top surface of the filtered material 2 and the upper end of the filter chamber 11. This provides ample space for the upper portion of the filtered material 2 to move during cleaning and drainage, preventing it from falling out of the filter chamber 11.

[0032] In order to further improve the structure of the filter box 1, and also make the filter box 1 have a better filtering effect on sewage, Figure 1As shown, the filter box 1 is also provided with a stirring chamber 12, a high-temperature disinfection chamber 13, a silver ion filter sterilization chamber 14, an ultraviolet sterilization chamber 15, and several overflow water channels 16; the stirring chamber 12, the high-temperature disinfection chamber 13, the filter chamber 11, the silver ion filter sterilization chamber 14, and the ultraviolet sterilization chamber 15 are arranged in sequence from left to right, and each chamber (i.e., between the stirring chamber 12 and the high-temperature disinfection chamber 13, between the high-temperature disinfection chamber 13 and the filter chamber 11, between the filter chamber 11 and the silver ion filter sterilization chamber 14, and between the silver ion filter sterilization chamber 14 and the ultraviolet sterilization chamber 15) is connected together through the overflow water channel 16, the water inlet overflow channel 101 is connected to the input end of the stirring chamber 12, and the water outlet overflow channel 103 is connected to the output end of the ultraviolet sterilization chamber 15. By setting up the overflow water channel 16, when sewage passes through each chamber, impurities in the sewage can be filtered and settled to the bottom of each chamber, so that the sewage filtered out of each chamber is clearer, thereby achieving the effect of multi-stage sewage filtration and improving the treatment quality of sewage. In actual application, the bottom of each chamber is provided with a slag switch channel 102 that runs through the outside of the filter box 1 to facilitate the discharge of impurities accumulated in each chamber. In actual application, if Figure 1 As shown, there are two filter chambers 11, and the two filter chambers 11 are connected together through an overflow water channel 16. This can improve the sewage filtration quality.

[0033] Specifically, the stirring chamber 12 is also equipped with a stirring mechanism 4. The high-temperature disinfection chamber 13 is equipped with an electric heating tube 131. The silver ion filter sterilization chamber 14 is equipped with a metal filter 141 coated with silver ions. The ultraviolet disinfection chamber 15 is equipped with an ultraviolet disinfection lamp 151. The stirring process of the sewage in the stirring chamber 12 disperses impurities in the sewage, which facilitates the comprehensiveness of subsequent high-temperature treatment and improves the quality of subsequent high-temperature disinfection. The high-temperature heating of the electric heating tube 131 sterilizes the sewage, reducing harmful organic matter in the sewage and thus reducing the chance of harmful bacteria growing. The filtration process in the filter chamber 11 filters particulate impurities in the sewage, further reducing harmful substances and ensuring that the discharged water is relatively clean, which is more conducive to disinfection. The silver ion sterilization process in the silver ion filter sterilization chamber 14 further sterilizes the clean water exiting the filter chamber 11, improving the quality of the sewage filtration process. Finally, the ultraviolet irradiation sterilization treatment in the ultraviolet sterilization chamber 15 can further sterilize the clean water coming out of the silver ion filter sterilization chamber 14, thereby improving the quality of sewage filtration treatment. The distribution of each level of the multi-stage sewage treatment device and the treatment functions achieved are very reasonable.

[0034] In actual application, the mesh diameter of the mesh plate portion 31 is smaller than the outer diameter of the filter material, and the mesh diameter of the mesh plate portion 31 is larger than the outer diameter of the impurities, so that impurities such as sludge and particulate matter in the sewage can pass through the mesh plate portion 31 and flow into the sedimentation space 111, and also prevent the filter material from falling into the sedimentation space 111.
