Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, in particular to a high-efficiency self-cleaning micro-electrolysis device. BACKGROUND

[0002] In the field of wastewater treatment, micro-electrolysis technology is widely used in the treatment of various industrial wastewater due to its efficient pollutant removal capability and good biodegradability improvement effect. This technology is based on the principle of corrosion electrochemistry, using iron with low electrode potential as the anode and particulate carbon with high electrode potential as the cathode. By using wastewater as an electrolyte solution, a large number of macroscopic and microscopic primary cells are formed in the water phase, thereby effectively removing pollutants in wastewater. This technology not only can degrade various macromolecular and difficult-to-biodegrade organic compounds, but also can significantly improve the biodegradability of wastewater, which has important significance for environmental protection and resource recovery.

[0003] In practical applications, in order to deal with the passivation of fillers, various means are adopted in the prior art. Common methods include aeration cleaning, hydraulic shearing, etc. Aeration cleaning removes the passivation film on the surface of the filler by introducing air into the system and using the impact force of the bubbles to remove the passivation film, while enhancing the potential difference of the primary cell reaction and promoting the dissolution of iron ions. Hydraulic shearing removes the pollutants and passivation layer on the surface of the filler by adjusting the speed and direction of the water flow to generate shear force. In addition, some devices periodically replace the filler or add physical cleaning devices to maintain the normal operation of the system. These methods can solve the problem of filler passivation to some extent, but still have certain limitations.

[0004] For the related technologies in the above, although the existing aeration cleaning and hydraulic shearing methods can solve the problem of filler passivation to some extent, there are still some defects in actual operation. For example, although aeration cleaning can effectively remove the passivation film, long-term aeration will cause excessive corrosion of iron, increase the consumption of fillers, and also increase energy consumption. Hydraulic shearing requires precise control of water flow speed and direction, which is complex to operate and difficult to achieve comprehensive cleaning effect. Therefore, how to effectively solve the problem of filler passivation while ensuring efficient treatment of pollutants has become a technical problem to be solved. CONTENT OF THE INVENTION

[0009] By adopting the above technical scheme, when the high-efficiency self-cleaning micro electrolytic device is needed, first, the high-efficiency self-cleaning micro electrolytic device is installed in the sedimentation tank in advance, when the wastewater in the sedimentation tank needs to be treated, the pumping element in the power component is started, the pumping element pumps the wastewater in the sedimentation tank to the water outlet, and the wastewater is sprayed to the annular filler box through the water outlet of the water outlet, so that the water contacts the filler in the annular filler box; The design of the annular filler box increases the contact area with water, promotes the decomposition reaction of iron-carbon filler, and improves the treatment efficiency; At the same time, by adjusting the power of the pumping element, sufficient contact time can be ensured between water flow and filler in low-speed mode, the decomposition reaction of the filler is enhanced, and the treatment effect is improved; In high-speed mode, the pollutants on the surface of the filler and the passivation layer on the surface are cleaned by high-speed water flow, the filler does not need to be additionally equipped with an aeration device or cleaned by a special person, the hardening and passivation of the filler are avoided, the service life of the filler is prolonged, and when the rotating water outlet water touches the annular filler box, it is equivalent to intermittent water inlet, the organic load of the filler is reduced, and the water quality is improved. This design not only improves the treatment efficiency, but also effectively solves the problem of filler passivation.

[0010] In one specific implementation, the rotating assembly further comprises a reinforcing member, the reinforcing member comprises four reinforcing ribs and a plurality of balls, the reinforcing ribs correspond to the water outlet pipes one by one, the reinforcing ribs are hollow, the reinforcing ribs are inclined upward from the connecting pipe to one side of the water outlet pipes, the lower end of the reinforcing ribs is connected to the connecting pipe, and the higher end is connected to the end of the water outlet pipes away from the connecting pipe, the plurality of balls are uniformly distributed in the four reinforcing ribs, the balls can roll in the reinforcing ribs, when the water pumping device is in the low position mode, the balls are located at the end of the reinforcing ribs close to the connecting pipe, and when the water pumping device is in the high position mode, the balls are located at the end of the reinforcing ribs away from the connecting pipe.

[0011] By adopting the above technical solution, the design of the reinforcing member can effectively improve the stability and cleaning effect of the water outlet pipes. The balls inside the reinforcing ribs increase the rotational inertia of the water outlet, avoiding the conversion of energy into invalid rotational kinetic energy of the water outlet. Specifically, the combination of the reinforcing ribs and the balls makes the water outlet pipes exhibit different rotational inertia characteristics in different working modes.

When the water pumping device is in the high position mode, the balls move to the end of the reinforcing ribs away from the connecting pipe, the rotational inertia increases, and the angular velocity of the water outlet pipe remains constant, maximizing the impact force of the water flow, effectively removing the pollutants and passivation layer on the surface of the filler, preventing the filler from hardening and passivating, and prolonging the service life of the filler. This design not only ensures the treatment effect, but also improves the self-cleaning ability of the device and reduces the maintenance cost.

When the water pumping device is in the high position mode, the balls gradually move upward and outward. According to the parallel axis theorem, the rotational inertia of the water outlet gradually increases, so that the angular velocity of the water outlet remains constant, avoiding energy waste and improving the cleaning effect of the water outlet.

[0014] In one specific implementation, the rotating assembly further comprises a fixing member, the fixing member comprises a fixing sleeve and four fixing rods, the fixing sleeve is sleeved at the joint of the fixing pipe and the connecting pipe, the fixing sleeve is fixed to the fixing pipe, the connecting pipe is rotationally connected to the fixing sleeve, the four fixing rods are evenly distributed along the circumference of the fixing sleeve, the fixing rods are inclined downward from the fixing pipe to one side of the bottom of the sedimentation tank, one end of the fixing rods is integrally connected with the fixing sleeve, and the other end is connected with the bottom of the sedimentation tank.

[0017] By adopting the above technical scheme, the plurality of limiting rings of the connecting member and the connecting pipe cooperate to ensure stable rotation of the connecting pipe on the fixing pipe, and the setting of the limiting ring and the limiting groove prevents axial movement of the connecting pipe, ensuring the reliability and stability of the rotating assembly; this not only improves the mechanical strength of the entire device, but also ensures that the water outlet pipe can accurately and smoothly rotate in different working modes, thereby improving the cleaning effect and processing efficiency of the device.

[0018] In one specific implementation, the processing assembly further comprises a water outlet weir, the water outlet weir comprises a water outlet cylinder and a water outlet ring, the water outlet ring is coaxially fixed to the outer wall of the water outlet cylinder, the water outlet ring is connected to the inner wall of the sedimentation tank, and the water outlet cylinder, the water outlet ring and the inner wall of the sedimentation tank form a discharge area for discharging water overflowed after processing in the sedimentation tank is completed.

[0038] Referring to Figure 2 , the power assembly 2 includes a water pumping device 21 and a fixed pipe 22, in this embodiment, the water pumping device 21 is a submersible pump, the pump body of the submersible pump is fixedly connected to the bottom of the sedimentation tank 4 by screws, and the submersible pump is located at the middle side of the bottom of the sedimentation tank 4, the fixed pipe 22 is in communication with the water inlet of the submersible pump, the fixed pipe 22 is fixedly connected to the submersible pump by screws, the fixed pipe 22 is made of stainless steel, and the fixed pipe 22 is perpendicular to the plane of the bottom of the sedimentation tank 4.

[0039] Referring to Figure 2 , Figure 3 and Figure 4The rotating assembly 3 comprises a connecting piece 31, a fixing piece 32, a rotating piece 33 and a reinforcing piece 34. The connecting piece 31 comprises a plurality of limiting rings 311 and a connecting pipe 312. The fixed pipe 22 is provided with a ring groove 221 at an end away from the bottom of the sedimentation tank 4. The ring groove 221 is coaxially arranged on the fixed pipe 22. The plurality of limiting rings 311 are located in the ring groove 221 and are uniformly distributed along the length direction of the fixed pipe 22. The limiting rings 311 are integrally connected with the fixed pipe 22. A limiting gap is left between the adjacent two limiting rings 311. The connecting pipe 312 is coaxially arranged on the top of the fixed pipe 22. The inner wall of the connecting pipe 312 is provided with a limiting groove 3121 matched with the limiting ring 311. A rotating sealing ring 3122 is arranged in each limiting groove 3121 of the connecting pipe 312. The rotating sealing ring 3122 is fixedly bonded on the connecting pipe 312. The rotating sealing ring 3122 seals the connecting position of the connecting pipe 312 and the fixed pipe 22. The connecting pipe 312 rotates around the axis of the fixed pipe 22. An end of the connecting pipe 312 away from the fixed pipe 22 is closed.

[0040] With reference to Figure 2 and Figure 3The rotating member 33 comprises four water outlets 331, which are located at the end of the connecting pipe 312 away from the fixed pipe 22 and are uniformly distributed along the circumference of the connecting pipe 312. One end of the water outlet 331 is communicated with the connecting pipe 312, and the other end is closed. The water outlet 331 is welded to the connecting pipe 312. The water outlet 331 is a circular arc pipe. The four water outlets 331 are located in a plane perpendicular to the axis of the connecting pipe 312. The four water outlets 331 are in a geometric spiral distribution. In order to reduce the water head loss in the water outlet 331, a water outlet 3311 is formed in the middle of the water outlet 331. When the water outlet 3311 touches the annular filler box 11, it is equivalent to intermittent water inlet, which reduces the organic load of the filler and improves the water quality. The design of the water outlet 3311 can be spiral or linear. The power of the submersible pump is adjusted to a low mode. At this time, the flow rate of the water outlet 3311 is small. When the low-speed water flow passes through the annular filler box 11, the water flow has sufficient contact time with the filler, which enhances the decomposition reaction of the filler and improves the treatment effect. When the power of the submersible pump is set to a high mode, the flow rate and lift of the submersible pump are increased, and the rotational speed of the water outlet 3311 is limited to avoid converting energy into invalid rotational kinetic energy of the water outlet 3311. The water outlet speed is increased. The high-speed water flow can clean the pollutants on the surface of the filler and the passivation layer on the surface, which avoids the hardening and passivation of the filler and prolongs the service life of the filler. The state of low-speed water flow and the state of high-speed water flow can be realized by adjusting the power of the water pump.

[0041] With reference to Figure 2 , Figure 3 and Figure 4 , the reinforcing member 34 comprises four reinforcing ribs 341 and a plurality of balls 342. The reinforcing rib 341 corresponds to the water outlet 331 one by one. The reinforcing rib 341 is inclined upward from the connecting pipe 312 to one side of the water outlet 331. The lower end of the reinforcing rib 341 is fixedly connected to the connecting pipe 312 by a screw. The higher end of the reinforcing rib 341 is fixedly connected to the end of the water outlet 331 away from the connecting pipe 312 by a screw. The reinforcing rib 341 can be made of stainless steel or aluminum alloy. The reinforcing rib 341 is hollow, and a guide groove 3411 is formed in the reinforcing rib 341. The guide groove 3411 is arranged in the same direction as the reinforcing rib 341. The plurality of balls 342 are uniformly distributed in the four reinforcing ribs 341. The ball 342 can be a steel ball or a ceramic ball. The ball 342 is located in the reinforcing rib 341 and rolls along the guide groove 3411. When the water flow speed is low, the ball 342 is located at the end of the reinforcing rib 341 close to the connecting pipe 312, and the moment of inertia is smallest, which has little effect on the rotation of the water outlet 331. When the water flow speed is high, the ball 342 gradually moves upward and outward. According to the parallel axis theorem I=T C +Md 2 , it can be known that (I represents the moment of inertia of the water outlet 331, T CThe moment of inertia of the water outlet 3311 is gradually increased, so that the angular velocity of the water outlet 3311 remains constant, according to the relationship M=Iβ between the combined moment M, the moment of inertia I and the angular acceleration β, when the water resistance and the recoil force of the water outlet 3311 are balanced, the angular acceleration is 0, that is, the angular velocity of the water outlet 3311 will remain unchanged; At this time, the water flow velocity perpendicular to the rotation direction of the water outlet 3311 reaches the maximum, and the filling flushing effect is also the best. This design effectively avoids the waste of energy, and improves the cleaning effect of the water outlet 3311.

[0042] The implementation principle of the high-efficiency self-cleaning micro-electrolysis device is as follows: when the high-efficiency self-cleaning micro-electrolysis device needs to be used, first, the high-efficiency self-cleaning micro-electrolysis device is installed in the sedimentation tank 4 in advance, when the wastewater in the sedimentation tank 4 needs to be treated, the water pumping part 21 in the power assembly 2 is started, the water pumping part 21 pumps the wastewater through the fixed pipe 22 to the connecting pipe 312, then the wastewater in the connecting pipe 312 enters the four water outlets 331 respectively, and is sprayed to the annular filler box 11 through the water outlet 3311 of the water outlet 331, so that the water contacts the filler in the annular filler box 11, and when the treatment operation is performed, the water in the sedimentation tank 4 flows to the discharge area through the water outlet weir 13.

[0043] When the wastewater needs to be pumped to the water outlet 331, the power of the submersible pump is adjusted to the low position mode, at this time the flow rate of the water outlet 3311 is small, and the low-speed water flow has sufficient contact time with the filler when passing through the annular filler box 11; the power of the submersible pump is set to the high position mode, the flow rate and the lift of the submersible pump are increased, and the rotation speed of the recoil water outlet 3311 is limited, so as to avoid converting the energy into invalid rotation kinetic energy of the water outlet 3311, increase the water outlet speed, and clean the pollutants on the surface of the filler and the surface passivation layer through the high-speed water flow.

[0044] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered in the protection scope of the present application.
