[0018] 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.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] In traditional wastewater treatment equipment, the collection and treatment of flocs generated after flocculation is inconvenient. When collecting flocs, wastewater needs to be pumped into the separation equipment, which makes the overall operation cumbersome and time-consuming, increasing the workload of the staff and causing inconvenience to the staff.

[0021] In view of this, the present invention provides an industrial wastewater deep treatment device. Through the cooperation of a sewage tank, an extraction device, an aggregation device, and a collection device, flocculants can be aggregated. When cleaning flocculants, only a small amount of sewage needs to be extracted to complete the cleaning work, thus effectively reducing the amount of sewage to be filtered, thereby shortening the overall operation time and improving the operation efficiency. Moreover, it can quickly filter and separate flocculants in sewage to ensure the quality of subsequent sewage treatment.

[0022] Example 1: By Figure 1 , 2 As shown in sections 3 and 4, an industrial wastewater deep treatment device includes a wastewater tank 1. A mounting frame 11 is fixedly connected to one side of the top of the wastewater tank 1. An inlet pipe 2 is fixedly connected to the inner wall of the mounting frame 11. A first drain pipe 10 is connected above the side of the wastewater tank 1 away from the inlet pipe 2, and a second drain pipe 12 is connected below the side of the wastewater tank 1 away from the first drain pipe 10. A partition 6 is fixedly connected to one side of the inner wall of the wastewater tank 1. A collection device 5 is installed below one side of the wastewater tank 1. The collection device 5 includes: a first filter screen 51, fixedly connected to the inner wall of one side of the partition 6; and an electric push rod 52, located below one side of the wastewater tank 1. The output end extends to the lower side of the interior of the sewage tank 1; the first push plate 53 is attached to the inner wall of the sewage tank 1, and its outer wall is fixedly connected to the output end of the electric push rod 52; the first limiting rail 54 is fixedly connected to the bottom of the inner wall of the sewage tank 1 and the lower side of the outer wall of the partition 6, and is slidably engaged with the bottom of the first push plate 53; the first cover plate 56 is fixedly connected to the lower side of the sewage tank 1; the sewage pipe 55 is connected to the inner wall of the first cover plate 56; wherein, flocculated impurities are discharged into the interior of the sewage tank 1 through the sewage pipe 55 with the water flow, and the remaining impurities are cleaned by opening the first cover plate 56, and the electric push rod 52 changes the position of the first push plate 53;

[0023] In the specific implementation process, it is worth noting that the two electric push rods 52 should be equipped with synchronizers so that the two electric push rods 52 can be controlled to work together synchronously. This allows the electric push rods 52 to better drive the first push plate 53 to move along the outer wall of the first limit rail 54. The model of the electric push rods 52 is not limited, as long as it meets the usage requirements. The mesh size of the first filter screen 51 is not limited, as long as it meets the usage requirements. It should be noted that the first filter screen 51 and the second filter screen 34 should be disassembled and cleaned regularly. The specific cleaning cycle is not limited, and the staff can choose according to the actual operation requirements to meet the actual usage requirements. The sewage pipe 55 and the second drain pipe 12 are both equipped with valves, and the staff can control the opening and closing status of the sewage pipe 55 and the second drain pipe 12 according to the operation situation.

[0024] Furthermore, the output end of the electric push rod 52 is fitted with a sealing ring 521, and the outer wall of the sealing ring 521 is fixedly connected to the inner wall of the sewage tank 1. A support plate 522 is fixedly connected to the upper part of the outer wall of the electric push rod 52, and the outer wall of the support plate 522 is fixedly connected to the outer wall of the sewage tank 1.

[0025] In the specific implementation process, it is worth noting that the sealing ring 521 can improve the sealing performance between the output end of the electric push rod 52 and the sewage tank 1, thereby avoiding sewage leakage. In addition, the staff should replace the sealing ring 521 and activated carbon 9 regularly to avoid the phenomenon of reduced performance due to long-term use.

[0026] Furthermore, activated carbon 9 is filled above the first filter screen 51, a perforated plate 8 is fixedly connected to the upper side of one side of the outer wall of the partition 6, and a second cover plate 7 is fixedly connected to the side of the sewage tank 1 near the perforated plate 8.

[0027] In the specific implementation process, it is worth noting that activated carbon 9 can remove Cd from wastewater. 2+ and Pb 2+ It can adsorb heavy metals and remove odors from sewage to improve the quality of sewage treatment. At the same time, sealing gaskets are provided at the connection between the second cover plate 7 and the first cover plate 56 and the sewage tank 1 to ensure the sealing performance during use.

[0028] Specifically, when using this industrial wastewater deep treatment device, wastewater containing flocculants enters the lower side of the inside of the wastewater tank 1. Then, the flocculants in the wastewater are filtered and blocked by the first filter screen 51. The wastewater is then purified by adsorption by activated carbon 9, passes through the perforated plate 8, and finally is discharged into the inside of the wastewater tank 1 through the first drain pipe 10. When cleaning the flocculants, the drain pipe 55 is opened, and the flocculants can flow out of the inside of the wastewater tank 1 with the water flow. For flocculants that cannot flow out, the first cover plate 56 can be opened to clean the flocculants when the water flow stops.

[0029] Example 2: From Figure 1 and 2It is known that an agglomeration device 3 is provided on the side of the sewage tank 1 away from the collection device 5. The agglomeration device 3 includes: a first servo motor 31, which is fixedly connected to the upper part of the side of the sewage tank 1 away from the first drain pipe 10; a threaded rod 32, which is rotatably connected to the inner wall of the sewage tank 1 and the partition 6 through a sealed bearing, and the end away from the first drain pipe 10 is fixedly connected to the output end of the first servo motor 31; a second push plate 33, which is threadedly connected to the outer wall of the threaded rod 32 and fits against the bottom of the inner wall of the sewage tank 1; a second filter screen 34, which is fixedly connected to the inner wall of the second push plate 33; and a second limiting rail 35, which is fixedly connected to the bottom of the inner wall of the sewage tank 1 and the lower part of the outer wall of the partition 6, and slides and engages with the bottom of the second push plate 33; wherein, the first servo motor 31 drives the second push plate 33 to agglomerate the flocs through the threaded rod 32.

[0030] In the specific implementation process, it is worth noting that the model of the first servo motor 31 is not limited, as long as it meets the usage requirements. The two first servo motors 31 should be equipped with synchronizers so that the synchronizers can control the two first servo motors 31 to move synchronously. This allows the first servo motors 31 to better utilize the threaded rod 32 to drive the second push plate 33 to move along the outer wall of the second limit rail 35. The mesh size of the second filter screen 34 is not limited, as long as it meets the usage requirements. It should be noted that the water level inside the sewage tank 1 should be lower than the position height of the threaded rod 32 to avoid the impact of flocculants on the threaded rod 32. Furthermore, an activated carbon filter box needs to be installed at the end of the second drain pipe 12. The activated carbon filter box should at least include: a box body, activated carbon, and connecting pipes, etc., to adsorb and purify the sewage discharged from the second drain pipe 12. The replacement cycle of the activated carbon should also be determined according to the actual operation situation.

[0031] Specifically, based on the above embodiment one, when the flocculants are aggregated, the first servo motor 31 is turned on, the first servo motor 31 drives the threaded rod 32 to rotate, and the threaded rod 32 can drive the second push plate 33 to move along the outer wall of the second limit rail 35, thereby allowing the flocculants to aggregate towards the first drain pipe 10, and the sewage can pass smoothly through the second filter screen 34. Then the second drain pipe 12 can be turned on, and the sewage can be discharged into the sewage tank 1 through the second drain pipe 12.

[0032] Example 3: From Figure 1 and 2 It is known that an extraction device 4 is installed above the sewage tank 1. The extraction device 4 includes: a pump body 41, which is installed above the sewage tank 1; a first conduit 42, which is connected to the input end of the pump body 41; and a second conduit 43, which is connected to the output end of the pump body 41. The pump body 41 extracts the flocculent and sewage on one side of the partition 6 into the other side of the partition 6 through the first conduit 42 and the second conduit 43.

[0033] In the specific implementation process, it is worth noting that the model of the pump body 41 is not limited, as long as it meets the usage requirements. The pump body 41 can extract sewage with flocculents through the first conduit 42, and then transport it to the other side of the partition 6 through the second conduit 43.

[0034] Furthermore, the bottom of the pump body 41 is fixedly connected to a horizontal plate 412 that is fixedly connected to the upper part of the inner wall of the sewage tank 1, and the inner wall of the horizontal plate 412 is fixedly connected to the upper part of the outer wall of the second conduit 43. The side of the horizontal plate 412 away from the second conduit 43 is fixedly connected to the outer wall of the first conduit 42 through a bracket. The outer wall of the pump body 41 is fitted with an isolation box 411 that is fixedly connected to the top of the horizontal plate 412. The output end and input end of the pump body 41 pass through both sides of the isolation box 411 respectively.

[0035] In the specific implementation process, it is worth noting that the isolation box 411 can isolate and protect the pump body 41. It should be noted that in actual use, the heat dissipation performance of the pump body 41 should also be ensured. The specific heat dissipation method is not limited and can be reasonably designed according to the actual use requirements.

[0036] Specifically, based on the above embodiment 2, once the flocs have accumulated, the pump body 41 can be turned on. The pump body 41 can then use the first conduit 42 and the second conduit 43 to pump the wastewater containing the flocs into the other side of the baffle 6 for separation treatment.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
