Technical Field
[0001] The utility model relates to the technical field of wastewater treatment, and particularly relates to an iron removal and purification device for hot-dip galvanized acidic rinsing wastewater. Background Art
[0002] Hot-dip galvanized acidic rinsing wastewater refers to the wastewater generated during the pickling treatment of metal surfaces with acids such as sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid, and phosphoric acid to remove metal surface oxides in the hot-dip galvanizing process. This kind of wastewater mainly comes from steel mills and electroplating factories, contains various metal ions, and is strongly acidic.
[0003] However, when the existing iron removal and purification device for hot-dip galvanized acidic rinsing wastewater is in use, chemical agents are usually used to make the iron ions in the wastewater become solids and precipitate. However, there are some small solid iron blocks mixed in the hot-dip galvanized acidic rinsing wastewater, which will adsorb on the inner wall of the tank frame where the hot-dip galvanized acidic rinsing wastewater is placed. The chemical reagents put into the hot-dip galvanized acidic rinsing wastewater cannot remove them, which has a certain impact on the quality and production cost of hot-dip galvanizing. Therefore, an iron removal and purification device for hot-dip galvanized acidic rinsing wastewater is provided. Summary of the Utility Model
[0004] The main purpose of the utility model is to provide an iron removal and purification device for hot-dip galvanized acidic rinsing wastewater. By setting a vibration motor, a filter screen, a servo motor, a coupling, an electric telescopic rod, a lead screw, a driving block, and an electromagnetic suction plate, the utility model solves the problem that the iron removal of the existing iron removal and purification device for hot-dip galvanized acidic rinsing wastewater is insufficient when in use.
[0005] The technical solution adopted by the utility model to solve its technical problems is an iron removal and purification device for hot-dip galvanized acidic rinsing wastewater, including a tank frame and a box body. A frame is bolted to the top of the tank frame, and a purification component for removing iron from the hot-dip galvanized acidic rinsing wastewater inside the tank frame is arranged on one side of the frame. The purification component includes a servo motor, a coupling, an electric telescopic rod, a lead screw, a driving block, and an electromagnetic suction plate. A servo motor providing power is bolted to the outside of the frame. The power output end of the servo motor is key-connected with a coupling, and a lead screw is key-connected to the inside of the coupling. A driving block moving horizontally is threadedly connected to the outside of the lead screw. An electric telescopic rod providing power is screwed to one side of the driving block, and an electromagnetic suction plate moving vertically is bolted to one side of the electric telescopic rod. A vibration motor for vibrating the tank frame is bolted to the outside of the tank frame. A pipe for allowing the hot-dip galvanized acidic rinsing wastewater to enter the inside of the box body is inserted into the bottom of the tank frame. A fixing frame is screwed to the top of the box body, and a filter screen for filtering and treating the hot-dip galvanized acidic rinsing wastewater is screwed to the inside of the fixing frame.
[0006] By adopting the above technical solution, when the hot-dip galvanized acidic rinsing wastewater enters the inside of the box frame, the external controller causes the electric telescopic rod on the driving block to drive the electromagnetic suction plate into the inside of the box frame. Subsequently, the electromagnetic suction plate adsorbs the small solid iron blocks in the hot-dip galvanized acidic rinsing wastewater. Then, the external controller causes the vibration motor outside the box frame to generate a centrifugal force when rotating at high speed through the adjustable eccentric blocks installed at both ends of the rotor shaft, forming an exciting force to drive the box frame to vibrate, so that the solid small iron blocks adhered to the inner wall of the box frame vibrate down to the bottom of the box frame. At the same time, the external controller causes the servo motor outside the frame to convert the received electrical energy into mechanical energy. The servo motor drives the lead screw to rotate, and the driving block outside the lead screw drives the electromagnetic suction plate on the electric telescopic rod to move horizontally, so that the electromagnetic suction plate adsorbs the small solid iron blocks in the hot-dip galvanized acidic rinsing wastewater at different positions in the box frame, and at the same time, lime milk is added into the box frame. The lime milk reacts with the iron ions in the hot-dip galvanized acidic rinsing wastewater to generate iron hydroxide precipitation. Subsequently, the external controller causes the valve on the pipeline to open, and then the hot-dip galvanized acidic rinsing wastewater in the box frame flows through the pipeline and flows downward into the inside of the box body. Then, the filter screen in the fixed frame at the top of the box body removes the precipitates in the hot-dip galvanized acidic rinsing wastewater, so as to facilitate the full iron removal and purification treatment of the hot-dip galvanized acidic rinsing wastewater;
[0007] When the lime milk is put into the box frame, the electromagnetic suction plate moves horizontally in the box frame, so that the electromagnetic suction plate stirs the lime milk and the hot-dip galvanized acidic rinsing wastewater, improving the mixing efficiency of the lime milk and the hot-dip galvanized acidic rinsing wastewater.
[0008] Specifically, a valve for controlling the flow rate of the hot-dip galvanized acidic rinsing wastewater is arranged outside the pipeline.
[0009] By adopting the above technical solution, the valve outside the pipeline controls the opening and closing of the pipeline, facilitating the hot-dip galvanized acidic rinsing wastewater in the box frame to flow into the inside of the box body.
[0010] Specifically, a support frame for supporting the box frame is bolted outside the box frame.
[0011] By adopting the above technical solution, the support frame outside the box frame supports the box frame, and the bottom of the support frame is bolted to the ground, thereby improving the stability of the box frame.
[0012] Specifically, the inner size of the driving block is the same as the outer size of the lead screw.
[0013] By adopting the above technical solution, when the driving block moves outside the lead screw, the inner side of the driving block fits with the outside of the lead screw. At the same time, the external limiting structure of the driving block limits the driving block, so that the driving block moves horizontally outside the lead screw, improving the stability of the driving block moving outside the lead screw.
[0014] Specifically, the input ends of the vibration motor, the servo motor, the electromagnetic suction plate, and the electric telescopic rod are all electrically connected to the power supply end of an external power supply.
[0015] By adopting the above technical solution, by connecting to an external power supply, the electrical equipment can work properly.

Subsequently, the electromagnetic suction plate adsorbs the small solid iron blocks in the hot-dip galvanized acidic rinsing wastewater. Then, the external controller causes the vibration motor outside the box frame to generate a centrifugal force when the adjustable eccentric blocks are installed at both ends of the rotor shaft during high-speed rotation, forming an exciting force to drive the box frame to vibrate, so that the small solid iron blocks adhered to the inner wall of the box frame vibrate and fall to the bottom of the box frame. At the same time, the external controller causes the servo motor outside the frame to convert the received electrical energy into mechanical energy. The servo motor drives the lead screw to rotate, and the driving block outside the lead screw drives the electromagnetic suction plate on the electric telescopic rod to move horizontally, so that the electromagnetic suction plate adsorbs the small solid iron blocks in the hot-dip galvanized acidic rinsing wastewater at different positions in the box frame, and at the same time, lime milk is added into the box frame. The lime milk reacts with the iron ions in the hot-dip galvanized acidic rinsing wastewater to generate iron hydroxide precipitation. Subsequently, the external controller opens the valve on the pipeline. Then, the hot-dip galvanized acidic rinsing wastewater in the box frame flows downward through the pipeline into the inside of the box body, and then the filter screen in the fixed frame at the top of the box body removes the precipitates in the hot-dip galvanized acidic rinsing wastewater, thus facilitating the full iron removal and purification treatment of the hot-dip galvanized acidic rinsing wastewater;
[0018] (2) For the iron removal and purification device of hot-dip galvanized acidic rinsing wastewater of the present utility model, when the lime milk is put into the box frame, the electromagnetic suction plate moves horizontally in the box frame, so that the electromagnetic suction plate stirs the lime milk and the hot-dip galvanized acidic rinsing wastewater, improving the mixing efficiency of the lime milk and the hot-dip galvanized acidic rinsing wastewater.

A fixed frame 9 is screwed to the top of the box body 10, and a filter screen 11 for filtering and treating the hot-dip galvanized acidic rinsing wastewater is screwed to the inside of the fixed frame 9.
[0025] When in use, when hot-dip galvanizing acid rinsing wastewater enters the box frame 2, the external controller causes the electric telescopic rod 14 on the driving block 4 to drive the electromagnetic suction plate 16 to enter the box frame 2, and then the electromagnetic suction plate 16 absorbs the solid small iron blocks in the hot-dip galvanizing acid rinsing wastewater. Then the external controller causes the vibration motor 5 outside the box frame 2 to generate centrifugal force when rotating at high speed through the adjustable eccentric blocks installed at both ends of the rotor shaft, forming an exciting force to drive the box frame 2 to vibrate, so that the solid small iron blocks adhered to the inner wall of the box frame 2 vibrate and fall to the bottom of the box frame 2. At the same time, the external controller causes the servo motor 12 outside the frame 3 to convert the received electrical energy into mechanical energy, and the servo motor 12 drives the screw rod 15 to rotate, and the screw rod 15 The external driving block 4 drives the electromagnetic suction plate 16 on the electric telescopic rod 14 to move horizontally, so that the electromagnetic suction plate 16 adsorbs the solid small iron blocks on the hot-dip galvanizing acid rinsing wastewater at different positions in the box frame 2, and at the same time, lime milk is introduced into the box frame 2, and the lime milk reacts with the iron ions in the hot-dip galvanizing acid rinsing wastewater to form iron hydroxide precipitation, and then the external controller opens the valve 8 on the pipeline 7, and then the hot-dip galvanizing acid rinsing wastewater in the box frame 2 flows downward through the pipeline 7 into the box body 10, and then the filter screen 11 in the top fixed frame 9 of the box body 10 removes the precipitate in the hot-dip galvanizing acid rinsing wastewater, so as to facilitate the full iron removal and purification of the hot-dip galvanizing acid rinsing wastewater;
[0026] When the lime milk is put into the box frame 2, the electromagnetic suction plate 16 moves laterally in the box frame 2, so that the electromagnetic suction plate 16 stirs the lime milk and the hot-dip galvanizing acid rinsing wastewater, thereby improving the mixing efficiency of the lime milk and the hot-dip galvanizing acid rinsing wastewater.
