Description

Technical Field

[0001] This utility model relates to the field of water recycling equipment technology, and in particular to a galvanizing wastewater recycling equipment. Background Technology

[0002] Electroplating wastewater refers to the wastewater generated during the electroplating production process, mainly originating from cleaning water for plated parts, waste electroplating solutions, and other wastewater. This wastewater contains various heavy metal ions, such as chromium, cadmium, nickel, copper, zinc, gold, and silver, as well as toxic substances such as cyanide, posing potential hazards to the environment and human health.

[0003] When recycling galvanizing wastewater, chemical additives are added to the wastewater to adsorb and precipitate floating metal impurities other than zinc. The liquid is then pumped out and filtered through a filter screen, blocking the deposited impurities on one side of the screen. However, this method has certain limitations. The long filtration time will cause the filter screen to become clogged, requiring timely disassembly and cleaning, which is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a galvanizing wastewater recycling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The enclosed decontamination mechanism includes multiple through holes on the upper surface of the isolation plate. Multiple sealing plates are slidably connected to the inner walls of the through holes. An adjusting shaft is rotatably connected to the inner wall of the sedimentation tank. A knob is fixedly connected to one end of the adjusting shaft. Multiple arc grooves are formed on the surface of the adjusting shaft. A linkage rod is fixedly connected to the surface of the sealing plate. One end of the linkage rod extends into the interior of the arc groove.

[0008] Preferably, a spring is fixedly connected to the inner wall of the transfer box, and an L-shaped plate is fixedly connected to one end of the spring. The surface of the L-shaped plate is in pressure contact with the surface of the multi-layer filter screen.

[0009] Preferably, a drain pipe is fixedly connected to the inner wall of the sedimentation tank, the surface of the drain pipe is in contact with the inner bottom wall of the sedimentation tank, and a sludge pump is installed on the surface of the drain pipe.

[0010] Preferably, a fixing plate is fixedly connected to the upper surface of the sedimentation tank, a motor is fixedly connected to the surface of the fixing plate, a lead screw is fixedly connected to the output end of the motor, and one end of the lead screw is rotatably connected to the inner wall of the fixing plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Add a chemical catalyst to the sedimentation tank. After settling, impurities slide down the inclined plane of the triangular plate and fall through the through hole into the spacer plate for collection.

[0015] 2. Under the action of the catalyst, the oil stains originally attached to the metal surface in the electroplating wastewater are separated and float on the surface of the wastewater. The second water pump drives the oil suction plate to pump water. The surface of the oil suction plate contacts the upper surface of the wastewater to perform the pumping operation, which can remove the oil stains floating on the wastewater.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 A galvanizing wastewater recycling device includes a sedimentation tank 1, an isolation plate 13 fixedly connected to the inner wall of the sedimentation tank 1, multiple transition pipes 3 fixedly connected to the inner wall of the sedimentation tank 1, a first water pump 4 fixedly connected to the surface of the transition pipes 3, a transfer tank 2 fixedly connected to one end of the transition pipes 3, a base 16 fixedly connected to the inner bottom wall of the transfer tank 2, multiple layers of filter screens 19 inserted into the inner wall of the base 16, and a closed decontamination mechanism opened on the upper surface of the isolation plate 13.

[0024] The enclosed decontamination mechanism includes multiple through holes 20 on the upper surface of the isolation plate 13. Multiple sealing plates 21 are slidably connected to the inner wall of the through holes 20. An adjusting shaft 15 is rotatably connected to the inner wall of the sedimentation tank 1. A knob 24 is fixedly connected to one end of the adjusting shaft 15. Multiple arc grooves 23 are opened on the surface of the adjusting shaft 15. A linkage rod 22 is fixedly connected to the surface of the sealing plate 21. One end of the linkage rod 22 extends into the interior of the arc groove 23.

[0025] In this invention, a first water pump 4 is installed to transport the wastewater deposited in the sedimentation tank 1 to the transfer tank 2. A base 16 is installed to ensure the stability of the multi-layer filter screen 19, allowing it to filter the wastewater discharged from the transfer pipe 3 multiple times. Multiple through holes 20 are installed to collect the metal or other impurities deposited and adsorbed in the sedimentation tank 1. Multiple sealing plates 21 are installed, and a seal is achieved when a pair of sealing plates 21 come close to each other. A knob 24 is installed, and the operator rotates the knob 24 to drive the adjustment shaft 15 to rotate for angle adjustment. A pair of arc grooves 23 are symmetrical about the center. The advantage of this is that when the adjustment shaft 15 rotates, the pair of arc grooves 23 drive the linkage rod 22 to move closer or further apart, thereby changing the distance between the pair of sealing plates 21. When the pair of sealing plates 21 come close together, a sealing effect is achieved.

[0026] A spring 18 is fixedly connected to the inner wall of the transfer box 2. One end of the spring 18 is fixedly connected to an L-shaped plate 17. The surface of the L-shaped plate 17 is in contact with the surface of the multi-layer filter screen 19.

[0027] In this invention, a spring 18 is provided to drive the L-shaped plate 17 to move and reset. The L-shaped plate 17 is provided to press the surface of the multi-layer filter screen 19, thereby maintaining the stability of the multi-layer filter screen 19 in use.

[0028] A drain pipe 11 is fixedly connected to the inner wall of the sedimentation tank 1. The surface of the drain pipe 11 is in contact with the inner bottom wall of the sedimentation tank 1. A sludge pump 12 is installed on the surface of the drain pipe 11.

[0029] In this invention, by setting up a drain pipe 11 and a sludge pump 12, the impurities deposited on the bottom wall of the sedimentation tank 1 are extracted so that they do not affect the galvanizing wastewater on the isolation plate 13. The advantage of doing so is that the impurities are centrally treated and discharged, preventing subsequent clogging of the multi-layer filter screen 19.

[0030] A fixing plate 5 is fixedly connected to the upper surface of the sedimentation tank 1. A motor 6 is fixedly connected to the surface of the fixing plate 5. A lead screw 7 is fixedly connected to the output end of the motor 6. One end of the lead screw 7 is rotatably connected to the inner wall of the fixing plate 5.

[0031] In this utility model, by setting up a motor 6, the operator starts the motor 6, and its output end drives the lead screw 7 to rotate. The rotation of the lead screw 7 changes the position of the conveying pipe 9 in the fixed plate 5, so that multiple oil suction plates 10 can pass over the surface of the wastewater in the sedimentation tank 1.

[0032] The screw 7 is threadedly connected to a conveying pipe 9, and multiple oil suction plates 10 are fixedly connected to the inner wall of the conveying pipe 9. A second water pump 8 is fixedly connected to the water outlet end of the conveying pipe 9.

[0033] In this invention, a second water pump 8 is installed, and multiple oil suction plates 10 are used to extract the floating oil located above the sedimentation tank 1, thereby removing the oil stains originally attached to the metal surface in the electroplating wastewater.

[0034] Multiple triangular plates 14 are fixedly connected to the upper surface of the isolation plate 13.

[0035] In this invention, by setting multiple triangular plates 14, after impurities settle, they are transported to the bottom of the isolation plate 13 through the inclined surfaces of the multiple triangular plates 14.

[0036] Working principle: During use, the galvanizing wastewater to be treated is transported to the sedimentation tank 1. A chemical catalyst is added to the sedimentation tank 1 to adsorb impurities in the wastewater. After settling, the impurities slide down the inclined surface of the triangular plate 14 and fall below the isolation plate 13 through the through hole 20. Then, the operator turns the knob 24, which drives the adjusting shaft 15 to rotate. The rotating adjusting shaft 15 passes through a pair of arc grooves 23, changing the linkage rods 22 located in the pair of arc grooves 23, so that the pair of linkage rods 22 move closer to each other. The movement of the pair of linkage rods 22 moves the pair of sealing plates 21 closer to each other, achieving a seal. Then, the motor 6 is started. The output end of the motor 6 drives the lead screw 7 to rotate. The rotation of the lead screw 7 drives the second water pump 8 and the conveying pipe 9 to move together, and the wastewater flows through the conveying pipe 9. Under the action of the catalyst, the oil stains originally attached to the metal surface in the electroplating wastewater are separated and floated on the surface of the wastewater. The second water pump 8 is started, and the surface of the oil suction plate 10 contacts the upper surface of the wastewater, causing multiple oil suction plates 10 to pump water. Then, the transfer pipe 3 is opened, and the first water pump 4 is started. The treated wastewater in the sedimentation tank 1 is filtered again through multiple layers of filter screen 19 and transported to the transfer tank 2. After the wastewater is transported, the adjusting shaft 15 is reversed, the through hole 20 is opened, and the sludge pump 12 is started. The impurities deposited below the isolation plate 13 are sucked out through the sludge pipe 11 to prevent impurities from clogging the multi-layer filter screen 19. With the above structure, the problem of frequent disassembly and cleaning of the filter screen due to wastewater clogging is prevented, and the oil stains floating on the wastewater can be removed.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
