Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge treatment technology, and in particular to an electrolytic sludge-water separation device. Background Technology
[0002] In the wastewater treatment industry, it is often necessary to separate sludge from wastewater. The sludge can then be dried and used for fertilizer production or construction, achieving efficient resource utilization. Common sludge-water separation methods include gravity sedimentation, filter press, flotation, and electrolysis. Gravity sedimentation relies on the density difference between sludge and water to achieve solid-liquid separation. Although it has a low cost, its processing efficiency is slow and it is difficult to separate fine particles. Filter press uses mechanical pressure to force dewatering, which consumes a lot of energy and the filter cloth is prone to clogging. Flotation uses the buoyancy of air bubbles to separate suspended solids, but it has problems such as small processing capacity and unstable bubble generation. Electrolysis stands out due to its high efficiency in solid-liquid separation. Electrolysis uses the electrolytic reaction of electrode plates to achieve sludge-water separation through electrocoagulation and electrodeposition. However, in actual use, the electrode plates are prone to forming a dense passivation layer due to anodizing and solution component deposition, which leads to a significant decrease in electrolysis efficiency. Therefore, the electrode plates often need to be cleaned. However, current cleaning methods mainly rely on physical scraping and spraying large amounts of chemical agents, which can easily damage the electrode plates and reduce their service life.

[0022] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.
[0023] See Figures 1 to 3This utility model provides an electrolytic mud-water separation device, including an electrolytic cell 1, an anode plate 2, a cathode plate 3, a female connector 4, and a cleaning mechanism. The top of the electrolytic cell 1 is open. The anode plate 2 and the cathode plate 3 are arranged opposite each other on the inner wall of the electrolytic cell 1. The female connector 4 is located on the outer wall of the electrolytic cell 1 and is electrically connected to the anode plate 2 and the cathode plate 3 through a wire 5. The cleaning mechanism includes an electric turntable 6, a rotating plate 7, a power supply box 8, a horizontal bar 9, a vertical bar 10, a first electric push rod 11, and a male connector 12. The electric turntable 6 is located below the electrolytic cell 1, and its rotating surface is connected to the bottom surface of the rotating plate 7. The power supply box 8 is located on the top surface of the rotating plate 7. One end of the crossbar 9 is connected to the side wall of the power supply box 8, and the other end is connected to the bottom end of the vertical rod 10. The first electric push rod 11 is located at the top of the vertical rod 10, and its output shaft is connected to the bottom end of the male terminal 12. The male terminal 12 is located below the female terminal 4. One end of the spring wire 13 is connected to the male terminal 12, and the other end is electrically connected to the power supply box 8 through the wire 5.
[0024] After the muddy wastewater is introduced into the electrolytic cell 1, the power supply box 8 is started. The electrical energy from the power supply box 8 is transmitted to the anode plate 2 through the positive electrode, wire 5, spring wire 13, male terminal 12, and female terminal 4. At the same time, it is transmitted to the cathode plate 3 through the negative electrode, wire 5, spring wire 13, male terminal 12, and female terminal 4. The anode plate 2 and cathode plate 3 realize the electrolysis of the muddy wastewater. During the electrolysis process, the metal cations generated by the anode plate 2 can neutralize the negative charge on the surface of colloids and fine suspended matter in the muddy wastewater, causing them to destabilize and aggregate to form larger flocs. The hydrogen gas generated by the cathode plate 3 can carry small-sized flocs to the water surface during the floating process, forming scum, thus achieving mud-water separation. After collecting the scum and flocs, they can be transferred to the next process for further dehydration and drying, so as to be used for fertilizer production or building material production, thereby improving resource utilization.
[0025] During long-term use, a passivation layer will form on the anode plate 2 and cathode plate 3. At this time, the first electric actuator 11 can be activated. The first electric actuator 11 drives the male terminal 12 to be pulled out from the female terminal 4. Then, the electric turntable 6 is activated, which drives the rotating plate 7 and the power supply box 8 to rotate. The power supply box 8 drives the first electric actuator 11 and the male terminal 12 to rotate through the horizontal bar 9 and the vertical bar 10, so that the positions of the male terminal 12 are interchanged, that is, the positive and negative positions of the power supply box 8 are reversed. Then the first electric actuator 11 can... The male terminal 12 is raised, and since the male terminal 12 is connected to the wire 5 by a spring, the male terminal 12 can be raised smoothly and inserted into the female terminal 4 to achieve power connection. At this time, the anode plate 2 and the cathode plate 3 are temporarily reversed, and the original anode plate 2 becomes the cathode. During the electrolysis process, the hydrogen gas generated by the cathode can peel off the passivation layer on the original anode plate 2, achieving non-destructive cleaning, avoiding damage to the anode plate 2 and the cathode plate 3, restoring the electrolysis function, and improving the mud-water separation efficiency.

The cleaning brush 19 is located on the side wall of the lifting box 18 away from the center of the electrolytic cell 1. The control panel 14 is electrically connected to the second electric push rod 17.
[0029] The second electric push rod 17 can drive the lifting box 18 to descend along the side wall of the anode plate 2. During the descent, the cleaning brush 19 can contact the surface of the anode plate 2 to clean the stripped passivation layer and improve the cleaning effect. The position of the cleaning brush 19 can be adjusted. When the electric turntable 6 drives the power box 8 to rotate, the horizontal bar 9 and the vertical bar 10 can drive the synchronous bar 15 to rotate together. Through the mounting rod 16, the lifting box 18 and the cleaning brush 19 are rotated to one side of the anode plate 2 or the cathode plate 3 to achieve the cleaning of the anode plate 2 or the cathode plate 3.
[0030] Preferably, the cleaning mechanism further includes a nozzle 20, which is disposed on the side wall of the lifting box 18 away from the center of the electrolytic cell 1 and communicates with the interior of the lifting box 18. The lifting box 18 stores cleaning agent, and the control panel 14 is electrically connected to the nozzle 20.
[0031] The nozzle 20 can spray the cleaning agent in the lifting box 18 onto the anode plate 2 or the cathode plate 3 to assist in cleaning. The amount of cleaning agent sprayed will not be excessive, so as to avoid secondary pollution to the muddy sewage.
[0032] Preferably, the cleaning mechanism further includes an electric slide 21 and an inclined plate 22. The top end of the synchronizing rod 15 is provided with a through groove 23. One end of the mounting rod 16 passes through the through groove 23.

[0033] The electric slide 21 can drive the mounting rod 16 to move along the through groove 23, thereby adjusting the position of the lifting box 18. An inclined plate 22 is provided on one side of the lifting box 18. The inclined plate 22 and the lifting box 18 form a collection chamber.

[0034] Preferably, the bottom surface of the passageway 23 is provided with a roller 24, and the bottom surface of the mounting rod 16 contacts the top surface of the roller 24.
[0035] When the mounting rod 16 moves along the through groove 23, its bottom can move under the drive of the roller 24 to ensure smooth movement.
[0036] Preferably, the cleaning mechanism further includes a replenishment pipe 25, which is disposed on the top surface of the lifting box 18, and an observation window 26 is provided on the side wall of the lifting box 18.
[0037] The cleaning agent level in the lifting tank 18 can be observed through the observation window 26. When the cleaning agent level in the lifting tank 18 is low, the cleaning agent can be replenished through the replenishment pipe 25.
[0038] Preferably, the system also includes a drain pipe 27 and a valve 28, wherein the drain pipe 27 is disposed on the bottom surface of the electrolytic cell 1 and the valve 28 is disposed on the drain pipe 27.
