Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment device for industrial wastewater. 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 becoming a part of the daily lives of ordinary people.

[0003] In industrial wastewater treatment, chemicals are added to the stored wastewater for mixing. To improve the mixing efficiency of the chemicals and save on labor costs in wastewater treatment, a motor-driven stirring rod is used as a mixing device to stir the wastewater.

[0004] However, existing mixing devices suffer from centrifugal effects when the mixing blades agitate the wastewater, which can lead to insufficient mixing and reduced efficacy of the chemicals. This results in substandard or poorly treated wastewater. Furthermore, during wastewater filtration pretreatment, prolonged use can clog the filter screen, affecting the filtration effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wastewater treatment device for industrial wastewater.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows: a wastewater treatment device for industrial wastewater, including a mixing tank, wherein the mixing tank is provided with a mixing and stirring assembly that rotates synchronously on its own axis and revolves around the sun, a support plate is fixedly connected to the inner side wall of the mixing tank, a filter screen is fixedly connected to the upper surface of the support plate, an impurity cleaning assembly is provided above the filter screen to clean it, the impurity cleaning assembly is drivenly connected to the mixing and stirring assembly, an impurity collection assembly that cooperates with the impurity cleaning assembly is provided on the top outer side wall of the mixing tank, a number of support legs are fixedly connected to the outer side wall of the mixing tank, and a liquid outlet pipe is connected through the bottom of the mixing tank, wherein a solenoid valve is installed inside the liquid outlet pipe.

[0007] Furthermore, the mixing assembly includes a motor fixedly installed at the bottom of the mixing tank. The output end of the motor passes through the bottom of the mixing tank and is fixedly connected to a cross-shaped fixing frame. A rotating shaft is fixedly connected at the central axis of the cross-shaped fixing frame. The top end of the rotating shaft passes through the top of the filter screen. A stirring shaft is rotatably connected to each of the four ends of the upper surface of the cross-shaped fixing frame. A stirring frame is fixedly connected to the outer side wall of the stirring shaft. A gear is fixedly connected to the top end of the stirring shaft. A gear ring is meshed with the outer side wall of the gear. The outer side wall of the gear ring is fixedly connected to the inner side wall of the mixing tank.

[0008] With the above technical solution, when mixing wastewater and chemicals, the motor is started to drive the cross-shaped fixed frame, the rotating shaft, and the stirring shaft to rotate. While the stirring shaft revolves around the rotating shaft, it drives the gear to rotate along the gear ring, and the stirring shaft rotates on its own axis. This drives each stirring frame to revolve and rotate synchronously, forming multi-dimensional mixing, effectively preventing the sedimentation of suspended solids in wastewater, improving the uniformity of chemical mixing, and ensuring that wastewater and chemicals are fully mixed.

[0009] Furthermore, the four stirring racks do not contact each other, and the stirring racks do not contact the mixing tank.

[0010] The above technical solutions reduce friction, extend service life, and prevent clogging while maintaining mixing efficiency.

[0011] Furthermore, the impurity cleaning assembly includes a rotating frame fixedly mounted on the top of the rotating shaft, and the lower surface of the rotating frame is provided with bristles.

[0012] Through the above technical solution, the filter screen one filters particulate impurities in the sewage. When the stirring shaft rotates, it drives the rotating frame to rotate. As the frame rotates, the brush bristles can automatically clean the impurities on the filter screen one, preventing impurities from accumulating on the filter screen one and causing blockage, which would affect normal filtration. The system has a high degree of automation and shares a motor drive with the mixing and stirring components to drive the stirring and cleaning components, thus reducing energy consumption.

[0013] Furthermore, the impurity collection assembly includes a guide channel fixed to the outer wall of the mixing tank, the bottom of the guide channel being an inclined surface, a collection box being connected through the lower outer wall of the guide channel, a collection drawer being slidably connected to the inner wall of the collection box, a filter screen being provided at the bottom of the collection drawer, and a flow pipe being connected through the bottom of the collection box to the side wall of the mixing tank.

[0014] With the above technical solution, when the rotating impurity cleaning component cleans impurities, the cleaned impurities fall into the guide channel due to the inertia of rotation, and are guided by the inclined surface to the collection box and collected by the collection tray. At the same time, the filter screen filters the residual sewage in the impurities. The filtered sewage flows back to the mixing tank through the flow pipe, separating the liquid and impurities, realizing the recycling of water resources and reducing waste. When cleaning impurities, the collection tray can be pulled out, making cleaning convenient.

[0015] Furthermore, the bottom end of the bristles contacts the upper surface of the filter screen, the mixing tank, and the guide channel, and the upper surfaces of the filter screen, the mixing tank, and the guide channel are located on the same plane.

[0016] The above technical solution ensures that impurities are thoroughly swept into the guide channel, avoiding residue.

[0017] Furthermore, a cover is rotatably connected to the side wall of the guide channel, and an inlet pipe is connected through the top of the cover.

[0018] The above technical solution makes it easy to add medicine or rinse through the inlet pipe, improving operational flexibility. At the same time, the cap can seal the guide channel to prevent odors or leakage.

[0019] The beneficial effects of this utility model are as follows:

[0020] (1) By setting up a mixing and stirring component, the mixing shaft drives the mixing frame to revolve around the rotating shaft while rotating on its own axis through the meshing of the gear ring, forming multi-dimensional mixing, effectively preventing the sedimentation of suspended solids in sewage and improving the uniformity of reagent mixing;

[0021] (2) The impurity cleaning component can automatically clean the impurities on the filter screen by rotating the brush bristles, so as to avoid the impurities from accumulating on the filter screen and causing blockage, which would affect normal filtration. It also shares a motor drive with the mixing and stirring component to drive the stirring and cleaning components, thus reducing energy consumption.

[0022] (3) The impurities are collected by the collection tray through the impurity collection component. At the same time, the wastewater remaining in the impurities is filtered and the filtered wastewater is returned to the mixing tank to separate the liquid and impurities, realize the recycling of water resources and reduce waste.

When mixing wastewater and chemicals, motor 201 is started to drive cross-shaped fixing frame 202, rotating shaft 203, and stirring shaft 204 to rotate. While stirring shaft 204 revolves around rotating shaft 203, it drives gears 206 to rotate along gear rings 207. Stirring shaft 204 rotates on its own axis, thereby driving each stirring frame 205 to revolve and rotate synchronously, forming multi-dimensional stirring, effectively preventing the sedimentation of suspended solids in wastewater, improving the uniformity of chemical mixing, and ensuring that wastewater and chemicals are fully mixed.

[0032] The impurity cleaning component 4 includes a rotating frame 401 fixedly installed at the top of the rotating shaft 203. The lower surface of the rotating frame 401 is provided with bristles 402. The filter screen 3 filters particulate impurities in the sewage. When the stirring shaft 204 rotates, it drives the rotating frame 401 to rotate.

A collection box 502 is connected through the lower outer wall of the guide channel 501. A collection tray 503 is slidably connected to the inner wall of the collection box 502. A filter screen 5031 is provided at the bottom of the collection tray 503. A flow pipe 504 is connected through the bottom of the collection box 502 and the side wall of the mixing tank 1. When the rotating impurity cleaning component 4 cleans the impurities, the cleaned impurities fall into the guide channel 501 due to the inertia of rotation. They are guided by the inclined surface 5011 to the collection box 502 and collected by the collection tray 503. At the same time, the filter screen 5031 filters the residual sewage in the impurities. The filtered sewage flows back to the mixing tank 1 through the flow pipe 504, separating the liquid and impurities, realizing the recycling of water resources and reducing waste. When cleaning the impurities, the collection tray 503 can be pulled out, making cleaning convenient.

[0036] The working principle of this embodiment is as follows: During use, sewage and chemicals enter the mixing tank 1 through the inlet pipe 601. The filter screen 3 filters the impurities in the sewage. At this time, the motor 201 is started to drive the cross-shaped fixing frame 202, the rotating shaft 203, and the stirring shaft 204 to rotate. While the stirring shaft 204 revolves around the rotating shaft 203, it drives the gear 206 to rotate along the gear ring 207, thereby achieving rotation. This drives each stirring frame 205 to revolve and rotate synchronously, forming multi-dimensional stirring, effectively preventing the sedimentation of suspended solids in the sewage and ensuring that the sewage and chemicals are fully mixed.

[0037] When the stirring shaft 204 rotates, it drives the rotating frame 401 to rotate. As the rotating frame 401 rotates, the brush bristles 402 can automatically clean the impurities on the filter screen 3, preventing impurities from accumulating on the filter screen 3 and causing blockage.
