Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an industrial wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. Among these, the treatment of industrial wastewater is even more important.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN217490012U) discloses a wastewater treatment device for dyeing and printing wastewater. This device solves the problems of long treatment times for sediment and suspended solids in dyeing and printing wastewater, inconvenient filter replacement, and easy clogging of the filter. The device includes a base with a support plate welded to its upper surface. A motor is mounted on the outer side of the support plate, and a shielding bucket is welded to the inner side of the support plate. A sliding seat is mounted on the upper surface of the base, with an mounting plate welded to one end. A screw is welded to the outer side of the mounting plate. A baffle is welded to the upper surface of the base, and a vertical plate is welded to the upper surface of the sliding seat. A water pipe connector is mounted on the outer side of the vertical plate, and a sleeve and a mounting ring are welded to the inner side of the vertical plate. Sediment and suspended solids in the dyeing and printing wastewater are filtered through a drum-type filter. The centrifugal force effectively accelerates the filtration process, and the filter is easy to disassemble and replace. The drum design reduces clogging under water flow, increasing the service life.

[0004] Although the aforementioned patent accelerates filtration and reduces filter clogging through centrifugal action using a drum-type structure during wastewater treatment, the filtered solid impurities still remain inside the drum. As the amount of solid impurities gradually increases, the filter screen will still experience partial clogging, thereby reducing its filtration effect and making it difficult to separate and process the filtered impurities in a timely manner, thus reducing the filtration efficiency of the device under long-term operation.

[0005] Therefore, this utility model provides an industrial wastewater treatment device to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides an industrial wastewater treatment device, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: an industrial wastewater treatment device, including a wastewater tank, wherein a drain pipe is integrally provided at the bottom of the wastewater tank, and supports are provided on both sides of the bottom of the wastewater tank.

[0031] 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.

[0032] like Figure 1-7 As shown, this utility model provides an industrial wastewater treatment device, including a wastewater tank 1, with a drain pipe 11 integrally installed at the bottom of the wastewater tank 1, and supports 12 installed on both sides of the bottom of the wastewater tank 1; a filter assembly 2, including an inlet pipe 21, with a drum filter screen 22 fixedly connected to one end of the inlet pipe 21, the drum filter screen 22 being rotatably installed inside the wastewater tank 1, and a first auger plate 23 and a baffle plate 24 fixedly connected to the inner wall of the drum filter screen 22; and a sewage discharge assembly 3, which extends into the interior of the drum filter screen 22 and is used for collecting and transferring solid impurities. The sewage discharge assembly 3 includes an auger pipe 31, with a second motor 32 fixedly connected to one end of the auger pipe 31, a main shaft 33 fixedly connected to the output end of the second motor 32, and a second auger plate 34 fixedly connected to the outer wall of the main shaft 33. The end of the inlet pipe 21 is connected to the water supply pipe through an external rotary joint. The device is connected, and driven by the rotation of the inlet pipe 21, the drum filter screen 22 rotates. When sewage enters the drum filter screen 22 through the inlet pipe 21, it is quickly discharged through the filter holes. At the same time, solid waste is spirally conveyed towards the second motor 32 with the cooperation of the first auger plate 23 and the baffle plate 24. At this time, the solid waste spirals upward under the obstruction of the baffle plate 24. When the baffle plate 24 tilts towards the axis of the auger pipe 31, the solid waste falls onto the surface of the collection plate 35 and further slides into the interior of the auger pipe 31. Then, under the rotation of the second auger plate 34, it is discharged through the end of the auger pipe 31. Thus, when the device is in use, it can achieve continuous solid-liquid separation of sewage and timely discharge of solid waste to avoid clogging of the drum filter screen 22, thereby improving the continuity and stability of the filtration operation of the device.

[0033] Furthermore, a sleeve is provided at the end of the drum filter screen 22 away from the water inlet pipe 21, and the inner and outer sides of the sleeve are respectively rotatably connected to the auger pipe 31 and the sewage tank 1. The sewage tank 1 is also rotatably connected to the outer wall of the water inlet pipe 21. A toothed ring 25 is fixedly connected to the outer wall of the water inlet pipe 21, and a gear 26 is meshed on the outside of the toothed ring 25. The output end of the first motor 27 is fixedly connected to the center of the gear 26, and the first motor 27 is fixedly connected to the outer wall of the sewage tank 1. The gear 26 is rotated by the drive of the first motor 27, and the toothed ring 25 is further rotated by the meshing of the gear 25, which in turn drives the water inlet pipe 21 and the drum filter screen 22 to rotate in a circular motion.

[0034] Furthermore, a feed trough is provided above the auger pipe 31, and collection plates 35 are fixedly connected to both sides of the feed trough. A partition plate 36 is fixedly connected to the end of the auger pipe 31 away from the second motor 32, and the end of the partition plate 36 near the water inlet pipe 21 has a conical structure. The partition plate 36 can guide and disperse the sewage entering the drum filter screen 22 from the water inlet pipe 21, and prevent the sewage from directly entering the interior of the auger pipe 31. The auger pipe 31, the drum filter screen 22 and the sewage tank 1 are coaxially distributed. A discharge port is provided at the bottom of the end of the auger pipe 31 near the second motor 32. The solid waste collected by the auger pipe 31 is discharged through the discharge port under the rotation and conveying of the second auger plate 34.

[0035] Furthermore, a flange ring 37 is fixedly connected to the outer wall of the auger pipe 31, and a positioning flange is integrally provided at the corresponding flange ring 37 of the sewage tank 1. A bolt passes through the flange ring 37 and is fixedly connected to the positioning flange of the sewage tank 1. This installation structure is mainly used for the installation and fixing of the auger pipe 31. At the same time, high-strength bolts are used to tighten the position to ensure the stability of the auger pipe 31 when inserted into the drum filter screen 22.

[0036] Furthermore, the middle section of the drum filter screen 22 is evenly provided with filter holes, and the length of the filter hole distribution is less than the length of the top guide groove of the drain pipe 11. The baffle 36 is located at the end of the filter hole distribution area close to the water inlet pipe 21.

[0037] Working principle: First, the end of the inlet pipe 21 is connected to the external sewage supply pipe through a rotary joint. Then, sewage enters the interior of the drum filter screen 22 through the inlet pipe 21. At this time, the rotation of the drum filter screen 22, through the setting of the first auger blade 23 and the baffle plate 24 on the inner wall, spirally lifts and transports the filtered solid waste until the baffle plate 24 tilts downward. The solid waste blocked by the baffle plate 24 falls above the collection plate 35 and further slides into the interior of the auger pipe 31. At this time, the main shaft 33 inside the auger pipe 31 drives the second auger blade 34 to rotate, realizing the guiding and transporting of solid waste, and timely discharge of the filtered solid waste, thereby improving the efficiency of solid-liquid separation of the device, ensuring the timeliness of solid waste separation, and thus improving the continuity of the filtration process of the device.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
