Description

Technical Field

[0001] This utility model relates to the field of electroplating wastewater treatment technology, specifically to an electroplating wastewater treatment and greywater reuse device. Background Technology

[0002] Electroplating wastewater contains a large amount of metal ions, such as copper, chromium, nickel, and zinc. These metal ions are highly toxic to water bodies and the ecological environment. Based on the properties and composition of the electroplating wastewater, pretreatment is necessary. Pretreatment mainly includes two steps: sedimentation and filtration. By adding appropriate amounts of precipitating agents such as calcium hydroxide or sodium hydroxide, suspended solids and some heavy metal ions in the wastewater are precipitated, removing suspended solids. Then, the wastewater is filtered to remove the precipitated solid particles, thus purifying the wastewater.

[0003] Utility model patent CN220723674U discloses an electroplating wastewater treatment and greywater reuse device. It solves the problem that current scraper blades easily reduce the moisture content of scraped suspended solids, leading to poor flowability and blockage of the discharge pipe. The new device uses locking bolts to adjust the tilt angle of the chute, causing the scraper to reposition itself and embed deeper into the sliding sleeve during its movement. This increases the water content of the suspended solids during separation and scraping, improving flowability and facilitating recycling. However, in practical use, the operator cannot easily adjust the locking bolts, and this method only prevents blockage by increasing the amount of water removed from the suspended solids. This method has significant limitations; when there are many suspended solids on the liquid surface, a large amount of suspended solids entering the discharge pipe can still easily cause blockage.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model employs a first motor that the operator can start to rotate, driving the first threaded rod to rotate, which in turn moves the movable plate, the first rotating shaft, and the separating frame downwards, allowing the separating frame to be inserted into a deeper position in the water. As the separating frame rotates, it can transport dirt and some water together into the drain cylinder, thus improving the flowability of the dirt. Then, the operator starts the separation frame to rotate, discharging suspended solids and some liquid into the drain cylinder via a guide frame.

[0020] like Figures 1 to 4 As shown, an electroplating wastewater treatment and greywater reuse device includes a workbench 1. From left to right, a mixing tank 2, an air bubble tank 3, and a slag separating cylinder 4 are fixedly connected to the top of the workbench 1. A drain cylinder 17 is fixedly connected to the surface of the slag separating cylinder 4 via a bracket. A drive box 5 is fixedly connected to the top of the workbench 1.

The surfaces of the first rotating shaft 10 and the second rotating shaft 11 are both fitted with synchronous pulleys 12, and the two synchronous pulleys 12 are connected by synchronous belt drive. The bottom of the first rotating shaft 10 is fixedly connected to the separation frame 13, and the bottom of the second rotating shaft 11 is fixedly connected to the spiral conveying rod 14. The top of the movable plate 7 is fixedly connected to the second motor 15, and the output end of the second motor 15 is fixedly connected to the first rotating shaft 10. The bottom of the dredging cylinder 17 is connected to the sewage pipe 18. The surface of the slag separating cylinder 4 is fixedly connected to the guide frame 16, and the outlet of the guide frame 16 is located above the dredging cylinder 17.

[0021] refer to Figure 1 , Figure 2 and Figure 4 An air pump 21 is fixedly connected to the right side of the bubble box 3. A support ring 19 is fixedly connected to the bottom of the movable plate 7 via a bracket. A nozzle 20 is fixedly connected to the surface of the support ring 19. The air outlet of the air pump 21 and the nozzle 20 are connected by a pipe.

[0022] As a technical optimization of this utility model, by setting up the air pump 21, the support ring 19 and the nozzle 20, the operator can start the air pump 21, so that the nozzle 20 sprays gas. The air outlet of the nozzle 20 is directed to the side away from the first rotating shaft 10, thereby blowing the suspended matter floating on the liquid surface to the side away from the first rotating shaft 10.

[0023] refer to Figure 1 and Figure 4An air pump 21 has an air inlet pipe 22 connected to its surface. A filter plate 23 is movably connected to the right side of the air inlet pipe 22. A bolt 24 is movably connected to the surface of the filter plate 23. The bolt 24 is threadedly connected to the air inlet pipe 22.

[0024] As a technical optimization of this utility model, by setting up the air intake pipe 22, the filter plate 23 and the bolts 24, the filter plate 23 can filter and remove dust from the gas entering the air intake pipe 22, and the operator can use the bolts 24 to install and fix the filter plate 23.

[0025] refer to Figure 1 and Figure 3 The inner wall of the slag separating cylinder 4 is provided with a groove, and a water level detector 25 is fixedly connected inside the groove. A controller 26 is fixedly connected to the front of the bubble box 3.

[0026] As a technical optimization of this utility model, by setting up the groove, the controller 26 and the water level detector 25, the water level detector 25 can detect the water level in the slag separating cylinder 4 in real time, and then transmit the detected data to the controller 26.

[0027] refer to Figures 1 to 4 A water tank 27 is fixedly connected to the right side of the workbench 1. A water inlet pipe is connected to the top of the water tank 27. A water pump 28 is connected to the right side of the water tank 27. The outlet of the water pump 28 extends to the inside of the slag separating cylinder 4 through a pipe. The controller 26 is connected to the water pump 28, the water level detector 25, the air pump 21, the first motor 8, and the second motor 15 respectively.

[0028] As a technical optimization of this utility model, by setting up the water tank 27, the water inlet pipe and the water pump 28, for example, when the water level in the slag separating cylinder 4 is low, the floating matter on the liquid surface in the slag separating cylinder 4 will also decrease. At this time, it is inconvenient for the separation frame 13 to discharge the suspended matter from the slag separating cylinder 4. At this time, the water pump 28 is started to add water into the slag separating cylinder 4, so that the liquid level in the slag separating cylinder 4 is always at the preset water level. Then, when the separation frame 13 rotates, it can discharge the suspended matter from the slag separating cylinder 4.

[0029] refer to Figure 1 The bottom of the workbench 1 is fixedly connected to the four sides of the cylinder 29. The cylinder 29 is internally threaded with a second threaded rod 30. The bottom of the second threaded rod 30 is fixedly connected with a support pad 31.

[0030] As a technical optimization of this utility model, by setting up the cylinder 29, the second threaded rod 30 and the support pad 31, the operator can rotate the second threaded rod 30, thereby driving the support pad 31 to move up or down, and thus adjust the horizontal state of the device.

[0031] The working principle and usage process of this utility model are as follows: During use, the mixing tank 2 stirs the flocculant. When the sewage enters the bubble tank 3, the bubble tank 3 generates a large number of bubbles, causing the suspended solids in the sewage to combine with the bubbles. After the sludge enters the separating cylinder 4, the sludge floats on the liquid surface. The operator can start the first motor 8 to rotate, which drives the first threaded rod 6 to rotate, thereby causing the movable plate 7, support plate 9, first rotating shaft 10 and separating frame 13 to move downward, so that the separating frame 13 is inserted into a deeper position in the water. Thus, when the separating frame 13 rotates, it can separate the sludge and some water. A piece is conveyed into the sludge cylinder 17 to improve the flowability of the sludge. Then, the operator starts the second motor 15 to rotate, which drives the first rotating shaft 10 to rotate, which in turn drives the separator 13 to rotate. When the separator 13 rotates, it can push the suspended matter to the edge of the sludge separating cylinder 4. Then, the suspended matter and some liquid are discharged into the sludge cylinder 17 through the guide frame 16. When the first rotating shaft 10 rotates, it drives the second rotating shaft 11 to rotate synchronously through the synchronous pulley 12 and the synchronous belt, which in turn drives the spiral conveyor 14 to rotate, thereby applying a downward force to the sludge in the sludge cylinder 17, so that the sludge can be discharged from the drain pipe 18.

[0032] After some water in the slag separating cylinder 4 is transported to the unclogging cylinder 17, the liquid level in the slag separating cylinder 4 will drop. In order to avoid the sludge from being difficult to discharge from the slag separating cylinder 4 due to the drop in liquid level, this device automatically replenishes water to the slag separating cylinder 4 by setting up a water level detector 25, a water pump 28 and a controller 26, so that the slag separating cylinder 4 is always at the preset liquid level, which makes it easier for the sludge floating on the liquid surface to be discharged from the slag separating cylinder 4.
