Description

Technical Field

[0001] This invention is an industrial wastewater circulating oxidation treatment device, belonging to the field of industrial wastewater treatment technology. Background Technology

[0002] Industrial wastewater is characterized by complex composition, high COD concentration, high toxicity, poor biodegradability, and easy deposition and scaling. Oxidation is the mainstream process for treating this type of wastewater. Currently, traditional oxidation treatment devices generally suffer from the following technical defects: 1. Simple stirring structure, mostly fixed-angle straight-plate paddles, resulting in a large water-facing area, high water flow resistance, and high energy consumption. Stirring can only form circumferential eddies, easily creating dead zones; 2. Uneven mixing of oxidant and wastewater, slow diffusion rate, local over-oxidation, and insufficient local reaction, leading to low treatment efficiency and poor effluent stability; 3. Lack of a longitudinal forced circulation mechanism, preventing rapid exchange between upper and lower wastewater layers, preventing bottom sediments from participating in the reaction, and easily causing clogging and scaling over long-term operation.

[0003] Although existing technologies have improved the mixing structure, they have not yet solved the core problems mentioned above, and therefore cannot meet the needs of modern industrial wastewater treatment for efficient and stable treatment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an industrial wastewater circulating oxidation treatment device.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: An industrial wastewater circulating oxidation treatment device includes a tank. A wastewater inlet pipe is provided on one side of the top of the tank, an oxidant addition port is provided on the other side of the top of the tank, and a liquid outlet pipe is provided at the bottom of the tank. A drive shaft is provided at the center of the tank body, and a motor is connected to the input end of the drive shaft. The motor is installed at the center of the top of the tank body. A rotary agitator is coaxially mounted on the drive shaft. A circulating jet mechanism is provided below the rotary agitator. An anti-deposition pushing mechanism is provided below the circulating jet mechanism at the bottom of the drive shaft. Multi-stage swirling guide ribs are provided on the inner wall of the tank body corresponding to the position of the rotary agitator.

[0006] Furthermore, the rotary cutting and stirring mechanism includes a main shaft sleeve, which is sleeved on the upper part of the drive main shaft. Rotary cutting arms are evenly arranged on the outer side of the main shaft sleeve, and a variable angle rotary cutting component is provided on the side of the rotary cutting arms away from the main shaft sleeve.

[0007] Furthermore, the variable angle rotary cutting assembly includes a second motor, which is fixedly mounted on the outer end of the rotary cutting arm. A fixing block is provided on the side of the second motor away from the rotary cutting arm, and a column is provided at the center of the side of the fixing block away from the second motor. An output shaft is connected to the output end of the second motor. The output shaft passes through the fixing block and the column and is connected to an L-shaped drive arm at the center of the side of the column. A cylinder is provided on the side of the L-shaped drive arm away from the output shaft. A connecting shaft is provided at the center of both sides of the outer side of the cylinder. The outer side of the connecting shaft is inserted into the center of the inner wall of the U-shaped frame. A third shaft is provided at the top and bottom of the U-shaped frame. A symmetrical L-shaped frame is provided on the side of the third shaft away from the U-shaped frame. The other end of the L-shaped frame is fixed to the top and bottom of the column. A first shaft is provided at the center of the side of the cylinder away from the L-shaped drive arm. A second shaft is provided on the side of the first shaft away from the cylinder. Side shafts are evenly provided on the outer side of the second shaft. Hyperboloid rotary cutting blades are provided on the side of the side shaft away from the second shaft. Several variable cross-section guide cone holes are provided at the center of the hyperboloid rotary cutting blades.

[0008] Furthermore, the front end of the variable cross-section guide cone hole faces outward, and the rear end faces inward. The front end is for liquid inlet, and the rear end is for jetting. The larger the swing angle, the greater the water flow resistance, automatically lowering the water-facing surface and increasing the rotary cutting cross-section.

[0009] Furthermore, the circulating jet circulation mechanism includes a circulating sleeve, an upper spiral guide vane, a lower spiral guide vane, a jet pressurization chamber, and a lateral jet orifice.

[0010] Furthermore, the annular sleeve is fitted onto the drive spindle, and several upper spiral guide vanes are fitted on the outer side of the annular sleeve. A disk is provided below the upper spiral guide vanes, and a through hole is provided in the middle of the disk. The drive spindle passes through the through hole, and a turntable is provided below the disk. The turntable is fitted onto the drive spindle, and several inclined guide grooves are evenly provided on the side of the turntable. A limiting rod is provided in the inclined guide groove, and the upper part of the limiting rod passes through the disk and is provided with an inclined guide plate. A conical guide cylinder is provided at the bottom of the turntable, and several lower spiral guide vanes are provided on the outer wall of the conical guide cylinder.

[0011] Furthermore, the bottom of the jet pressurization chamber is connected to the top of the anti-deposition pushing mechanism, and both the disc and the turntable are located inside the jet pressurization chamber. The jet pressurization chamber has an inverted conical structure, and several lateral jet holes are provided on the upper wall of the jet pressurization chamber.

[0012] Furthermore, the circulating sleeve cooperates with the swirling guide ribs on the inner wall of the tank to transform the circumferential flow into a spiral swirling flow, thus avoiding vortex dead zones.

[0013] Furthermore, the anti-deposition pushing mechanism includes a conical pushing disk, inclined pushing blades, and a suction port.

[0014] Furthermore, the conical pusher disk is fixed to the bottom of the drive spindle, the oblique pusher blades are fixed on the conical pusher disk, and several suction ports are evenly provided at the bottom of the conical pusher disk near the middle.

[0015] The beneficial effects of this invention are: The variable-angle rotary cutting component allows for variable-angle adjustment of the hyperboloid rotary cutting blades. The larger the blade swing angle, the greater the water flow resistance. The wastewater concentration, viscosity, and flow rate will automatically adjust the angle of attack. In high-viscosity conditions, the resistance will be automatically reduced, and in low-viscosity conditions, the stirring will be strengthened, thereby improving the stirring effect. The variable cross-section guide cone holes on the blades form a high-speed jet during rotation, which forms a bidirectional jet collision with the side jet holes, allowing the oxidant entering the interior to diffuse evenly throughout the entire area in a short time, thereby increasing the oxidation reaction rate.

[0016] The upper spiral guide vanes in the circulating jet mechanism rotate with the main shaft, pressing the upper wastewater downwards. This causes the water to enter the inverted conical jet pressurization chamber and be pressurized. The water is then sprayed horizontally through the lateral jet holes, where it merges with the jet from the rotary shearing blades to form a strong turbulent zone. Meanwhile, the lower spiral guide vanes work in conjunction with the conical guide tube to guide the bottom water upwards, forming a closed-loop forced circulation that ensures uniform diffusion of the oxidant throughout the entire area.

[0017] The anti-deposition pushing mechanism drives the conical pushing disk and the inclined pushing blades to rotate through the main shaft, which gathers the sediment at the bottom of the tank towards the center and generates an upward thrust. This lifts the sedimented wastewater and suspended solids through the suction port to the circulating jet mechanism, where they re-participate in the oxidation reaction, completely eliminating the dead zone and sediment caking at the bottom. In particular, the multi-stage swirling guide ribs on the inner wall of the tank convert the rotating water flow into a spiral upward flow, breaking the eddy short circuit, extending the actual residence time of the wastewater, increasing the contact area of ​​the gas, liquid and solid phases, and significantly improving the efficiency and completeness of the oxidation reaction.

[0025] See Figure 7 The anti-deposition pushing mechanism 9 includes a conical pushing disk 901, an inclined pushing blade 902, and a suction port 903. The conical pushing disk 901 is fixed to the bottom of the drive spindle 5, and the inclined pushing blade 902 is fixed on the conical pushing disk 901.

[0026] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0027] When in use, wastewater enters tank 1 through wastewater inlet pipe 2, oxidant is added through oxidant addition port 3, motor 6 is started to drive the drive shaft 5 to rotate, and the drive shaft 5 drives the rotary stirring mechanism 7, the circulating jet circulation mechanism 8 and the anti-deposition pushing mechanism 9 to operate synchronously. The drive spindle 5 drives the spindle sleeve 701 to rotate, which in turn drives several uniformly arranged rotary cutting arms 702 to rotate coaxially. Each rotary cutting arm 702 drives the variable-angle rotary cutting assembly 703 connected to its outer end to rotate. After the variable-angle rotary cutting assembly 703 rotates, the hyperboloid rotary cutting blade 7043 achieves adaptive oscillation during rotation. The motor 7031 drives the L-shaped drive arm 7034 to oscillate, thereby adjusting the angle between the cylinder 7035 and the hyperboloid rotary cutting blade 7043. The connecting shaft 7036 on the side of the cylinder 7035 drives the outer spiral frame 7037. The oscillating cylinder 7035 rotates, driving the outer second shaft 7041 to rotate as well. The hyperboloid rotary cutting blades 7043 on the side of the second shaft 7041 rotate along with it. The wastewater from the surrounding water flow jets out from the variable cross-section guide cone hole 7044, enabling the hyperboloid rotary cutting blades 7043 to achieve adaptive angle adjustment. The greater the water flow resistance, the greater the blade oscillation angle, which automatically reduces the water-facing surface, thereby reducing resistance and increasing the rotary cutting coverage. At the same time, the variable cross-section guide cone hole 7044 on the blade forms a high-speed jet, instantly breaking up the water flow, thus dispersing the oxidant and eliminating the stirring dead zone. Secondly, after the drive shaft 5 rotates, it drives the upper spiral guide vane 802 to rotate, which will push the upper wastewater downward. The water flow enters the inverted conical jet pressurization chamber 804 and is pressurized. The pressurized wastewater is driven by the rotation of the upper spiral guide vane 802 and is sprayed horizontally from the side jet hole 805. The horizontally sprayed water flow merges with the jet formed by the hyperboloid rotary shearing blade 7043 to form a high-intensity turbulent mixing zone. The lower spiral guide vane 803 cooperates with the conical guide tube 812 to guide the bottom water flow upward, forming an upper and lower closed-loop forced circulation, so that the oxidant is evenly diffused throughout the entire area. Finally, by driving the main shaft 5 to drive the conical pusher disk 901 and the inclined pusher blade 902 to rotate synchronously, the sediment at the bottom of the tank 1 is guided and gathered to the center, and an upward thrust is generated. The sedimented wastewater and suspended solids are lifted through the suction port 903 to the circulating jet circulation mechanism 8 to re-participate in the oxidation reaction, thus eliminating the bottom dead zone and sediment caking problem from the root. The multi-stage swirling guide ribs 10 on the inner wall of the tank body 1 convert the rotating water flow into a spiral upward flow, break the eddy short circuit, prolong the actual residence time of the wastewater, increase the contact area of ​​the gas-liquid-solid three phases, and significantly improve the efficiency and completeness of the oxidation reaction; after the wastewater is treated, it is stably discharged from the bottom outlet pipe 4.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
