[0027] Referring to Figures 1-5 An embodiment of the present application provides an automatic slag discharge device of a baffle traveling type BDD wastewater treatment equipment, which comprises a reaction tank 1 and a pump 6, a plurality of electrolysis modules 2 and a slag discharge frame 3 are arranged in the reaction tank 1, the slag discharge frame 3 is arranged above the electrolysis modules 2, the bottom of the slag discharge frame 3 is a closed panel, and the side edges are sawtooth-shaped, the slag discharge frame 3 is connected with a slag discharge pipe 10, the slag discharge opening of the slag discharge pipe 10 is located outside the reaction tank 1, the slag discharge pipe 10 is connected with the pump 6, the pump 6 is used for pumping wastewater containing floating slag in the reaction tank 1, and the two sides of the slag discharge frame 3 are connected with a buoyancy adjusting assembly 4, and the buoyancy adjusting assembly 4 is used for adjusting the position of the slag discharge frame 3.

[0028] The embodiment improves the slag discharge structure of the existing wastewater treatment equipment, and increases the slag discharge frame 3, the slag discharge pipe 10, the buoyancy adjusting assembly 4 and the circulating pump in the wastewater treatment equipment, wherein the slag discharge frame 3, in combination with the slag discharge pipe 10 and the circulating pump, can collect and discharge the floating slag floating on the water surface in the reaction tank 1, so that the accumulation of the floating slag in the reaction tank 1 is avoided, the buoyancy adjusting assembly 4 can adjust the position of the slag discharge frame 3, so that the device can adapt to the dynamic requirements of different water level changes and floating slag production amounts, and the treatment efficiency of the wastewater is improved.

[0029] In the embodiment, the slag discharge frame 3 floats on the water surface, the slag discharge opening of the slag discharge frame 3 is located below the water surface, the slag discharge frame 3 can be made of corrosion-resistant material, so that it can withstand the corrosion of chemical substances in the wastewater for a long time, and the service life of the equipment is prolonged. Figure 3 The bottom of the slag discharge frame 3 is a closed panel, and the side edges are sawtooth-shaped, so that the floating slag in the wastewater can be collected into the slag discharge frame 3 through the sawtooth-shaped edges.

[0030] Further, the buoyancy adjusting assembly 4 comprises a float box 41 and a guide component 42. The float box 41 is connected to both sides of the slagging frame 3, and the guide component 42 is arranged on one side of the float box 41 to provide a path and support for the lifting and lowering movement of the float box 41 and the slagging frame 3, ensuring the stability of the slagging frame 3 during lifting and lowering, and preventing damage to the equipment or low processing efficiency caused by deflection or jamming. In this embodiment, the float box 41 is used to provide buoyancy for the slagging frame 3, wherein the height of the float box 41 is higher than the water surface and the slagging frame 3, which can effectively prevent the slagging frame 3 from tilting or sinking due to insufficient buoyancy or water flow impact. Specifically, in this embodiment, the float box 41 can be fixedly connected to the slagging frame 3 by screws, welding or other fasteners, or can be movably connected to the slagging frame 3 by sliding or hinging, and the connection mode is not limited here.

[0031] Further, the guide component 42 comprises a guide rod 421 and a guide sleeve 422. The guide sleeve 422 is connected to both sides of the slagging frame 3, and the guide sleeve 422 is located on one side of the float box 41. The guide sleeve 422 is sleeved on the guide rod 421, and the guide sleeve 422 is used to move up and down along the guide rod 421. In this embodiment, the guide sleeve 422 is fixed on both sides of the slagging frame 3 and is sleeved on the guide rod 421. The inner diameter of the guide sleeve 422 is slightly larger than the outer diameter of the guide rod 421 to ensure smooth movement of the slagging frame 3 when moving up and down. Specifically, the guide sleeve 422 is made of anti-slip material, and when the guide sleeve 422 is sleeved on the guide rod 421, the guide sleeve 422 and the guide rod 421 have friction between them, which can prevent the slagging frame 3 from suddenly accelerating or decelerating during movement due to external forces, thereby maintaining the stability of its movement. When the float box 41 provides buoyancy for the slagging frame 3, the slagging frame 3 will move up and down along the guide rod 421. Due to the presence of the guide sleeve 422, the movement trajectory of the slagging frame 3 is limited within the range of the guide rod 421, thereby ensuring the accurate position of the slagging frame. In addition, the guide sleeve 422 can also absorb and buffer the impact force generated during the movement of the slagging frame 3 to a certain extent, protecting the guide rod 421 and the slagging frame 3 from damage.

[0032] Further, one end of the slag discharge pipe 10 is connected with a flexible joint 5, and the other end of the flexible joint 5 is connected with the slag discharge frame 3. In the embodiment, the flexible joint 5 is used to compensate the position change of the slag discharge frame 3 when the slag discharge frame 3 moves up and down. The slag discharge frame 3 needs to move up and down under the action of buoyancy under the water surface, and the slag discharge pipe 10 is usually fixed outside the reaction tank 1. When the slag discharge frame 3 moves up and down, the flexible joint 5 can flexibly stretch and bend to adapt to the constantly changing relative position between the slag discharge frame 3 and the slag discharge pipe 10, so that the slag discharge frame 3 can be effectively connected with the slag discharge pipe 10 regardless of the height of the slag discharge frame 3, thereby smoothly discharging the scum, reducing the labor intensity of the operator, and improving the treatment efficiency of the wastewater.

[0033] Further, the pump 6 is a circulating pump, and an inlet pipe 61 is arranged on the circulating pump, the inlet pipe 61 is communicated with the slag discharge pipe 10, and the circulating pump is used to suck the wastewater containing scum in the reaction tank 1. In the embodiment, the wastewater containing scum in the reaction tank 1 can be sucked and circulated by adding the circulating pump, so as to promote the removal of pollutants and the separation of scum in the wastewater.

[0034] Further, a filter 7 is further included, the circulating pump is communicated with the filter 7, and the filter 7 is used to filter the scum wastewater. Specifically, when the scum wastewater enters the filter 7 from the circulating pump, the wastewater first passes through the filter medium (such as a filter bag, a filter screen or a filter layer), which can intercept the suspended solids and particulate matters in the wastewater, so that these impurities are accumulated on the surface of the filter medium to form a filter layer, and at the same time, the dissolved pollutants in the wastewater can also be removed by the filter medium through adsorption, chemical reaction and the like. The wastewater after the filtration treatment flows out from the outlet of the filter 7 and enters the water inlet pipe 12 of the reaction tank 1 for recycling treatment. In order to ensure the continuous and efficient operation of the filter 7, the filter bag needs to be cleaned regularly.

[0035] In the embodiment, a pressure gauge 71 is further arranged on the filter 7, which is used to monitor the working pressure and filtration efficiency of the filter 7 in real time. When the pressure abnormally rises or falls, it means that there may be blockage, leakage or other faults in the filter 7, and the filter 7 needs to be repaired in time. By comparing the inlet pressure and the outlet pressure, the resistance loss of the filter 7 can be calculated, and then the filtration efficiency of the filter 7 can be evaluated. The greater the resistance loss is, the higher the blockage degree of the filter 7 is, and the filter medium needs to be cleaned or replaced. At the same time, when the pressure of the filter 7 reaches the upper limit pressure, the control system can send an alarm signal to remind the user to clean the filter medium in time.

[0036] Further, a slag discharge pipeline 8 is provided, one end of which is communicated with the slag discharge pipeline 10 and the other end of which is communicated with the inlet pipeline 61. In this embodiment, when the slag discharge frame 3 moves up and down under the action of buoyancy, the floating slag is collected into the slag discharge frame 3. Then, the floating slag in the slag discharge frame 3 is transported into the inlet pipeline 61 of the circulating pump through the slag discharge pipeline 8 by suction of the circulating pump. Under the action of the circulating pump 6, the floating slag is sucked and pressurized together with the wastewater to form a wastewater mixture containing floating slag and is transported into the filter 7.

[0037] Further, electric valves are provided, including a first electric valve 91 and a second electric valve 92, the first electric valve 91 is arranged on the slag discharge pipeline 8 and the second electric valve 92 is arranged on the inlet pipeline 61. In this embodiment, the first electric valve 91 is arranged on the slag discharge pipeline 8 and is used to control the opening and closing of the slag discharge pipeline 8. When the system needs to discharge slag, the first electric valve 91 is opened to allow the floating slag wastewater to be discharged out of the reaction tank 1, and when the system does not need to discharge slag or is under maintenance, the first electric valve 91 is closed to cut off the flow of the slag discharge pipeline 8 to prevent unnecessary loss and pollution of the wastewater. The first electric valve 91 is opened and closed by receiving signals from the control system. When the control system detects that the slag discharge condition is met (e.g., the floating slag accumulates to a certain amount), the first electric valve 91 is sent an opening signal, the first electric valve 91 is opened and slag discharge is performed, and when the slag discharge time is reached, the first electric valve 91 is sent a closing signal, the first electric valve 91 is closed. The second electric valve 92 is arranged on the inlet pipeline 61 and is used to control the entry of the floating slag wastewater into the circulating pump 6. When the system needs to treat wastewater, the second electric valve 92 is opened to allow the wastewater to enter the circulating pump 6 from the inlet pipeline 61, and when the system needs to be shut down or is under maintenance, the second electric valve 92 is closed to cut off the inflow of the wastewater to prevent the system from being contaminated or damaged. Similarly, the second electric valve 92 is also opened and closed by receiving signals from the control system.

[0038] Further, the reaction tank 1 is provided with a water inlet pipeline 13 and a water outlet pipeline 14 at two ends respectively, the water inlet pipeline 13 is connected with an external water source, and the water outlet pipeline 14 is communicated with the filter 7. In this embodiment, a flow regulating device can be installed on the water inlet pipeline 13 to control the flow of wastewater from the external water source into the reaction tank 1, so as to ensure that the wastewater flows into the reaction tank 1 at a stable and appropriate speed, avoiding problems such as low treatment efficiency or poor treatment caused by flow fluctuation. The materials of the water inlet pipeline 13 and the water outlet pipeline 14 are high-strength and corrosion-resistant materials to ensure that they can withstand high water pressure and corrosive substances in the wastewater during long-term operation, thereby prolonging the service life and reducing the maintenance cost.

[0039] Further, the reaction tank 1 is provided with a plurality of transverse partitions 12 and longitudinal partitions 11, the transverse partitions 12 and the longitudinal partitions 11 intersect to divide the reaction tank 1 into a plurality of reaction chambers, and the electrolysis module 2 is arranged in the reaction chambers to treat wastewater by electrochemical action. The longitudinal partitions 11 include a first longitudinal partition 111 and a second longitudinal partition 112, the upper end of the first longitudinal partition 111 is connected to the top end of the reaction tank 1, and the lower end extends to a position close to the bottom of the reaction tank 1, but is not connected to the bottom of the reaction tank 1, and has a certain space for free flow of wastewater; the lower end of the second longitudinal partition 112 is connected to the bottom of the reaction tank 1, and the upper end extends to a position close to the top end of the reaction tank 1, but is not connected to the top end of the reaction tank 1, and has a certain space for free flow of wastewater. Through such a design, the straight flow of water is changed, the wastewater forms multiple turns inside the equipment, the residence time of the water flow in the equipment is prolonged, which is helpful for the wastewater to be more fully contacted and reacted with the electrolysis module 2, and the treatment efficiency is improved. In this embodiment, the guide rod 421 is fixedly connected to the longitudinal partition 11.

[0040] The above is only an optional embodiment of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection range of the present application.
