Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an adsorption-type wastewater treatment device. Background Technology

[0002] With the acceleration of industrialization and urbanization, the demand for wastewater treatment is increasing. Adsorption wastewater treatment technology has been widely used in industrial wastewater treatment and municipal sewage deep purification due to its high efficiency and flexibility. This technology uses electromagnetic adsorption, magnetic media adsorption or chemical adsorption to concentrate metal residues in wastewater on the surface of the adsorption carrier, thereby purifying the water.

[0003] In existing equipment, the adsorption net is usually fixed inside the equipment by bolts or rigid clips. Disassembly requires manual shutdown. For example, CN214299431U discloses a magnetic adsorption sewage treatment device, including a device body, a linkage mechanism, and a disassembly mechanism. The top of the device body is connected to a support rod, and a linkage mechanism is provided on one side of the support rod. The bottom of the linkage mechanism is connected to a rotating rod, and a bearing sleeve is provided at the bottom of the rotating rod. A rotating long rod is connected to the bottom of the bearing sleeve, and a magnetic rod is provided on one side of the rotating long rod. Sewage is introduced into the device body through the inlet, and then the motor is started by an external power source, so that the motor drives the first rotating rod to rotate the first rotating rod. When the drive gear rotates, the rotation of the first rotating gear will drive the rotation of the second rotating gear through the action of the internal toothed belt. This allows the rotating rod to drive the magnetic rods and removable adsorption nets on both sides to stir the sewage inside the equipment body. The magnetic rods have magnetic adsorption force, which can enhance the adsorption efficiency of impurities. However, when the magnetic rods adsorb, the removable adsorption net is used. One end of the removable adsorption net is fixed by a fixing hook. During the disassembly process, one end of the removable adsorption net needs to be peeled off, so that the magnetic attraction of the magnetic rods on the metal residues gradually decreases. At this time, the metal residues attached to the surface of the removable adsorption net, such as iron filings and iron oxide scale, are easily detached due to vibration or water flow impact, resulting in secondary pollution of the treated sewage.

[0004] Therefore, it is necessary to provide a new adsorption-type wastewater treatment device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an adsorption-type sewage treatment device.

[0006] The adsorption-type sewage treatment equipment provided by this utility model includes: an equipment body and a mounting frame. The mounting frame is located on one side of the equipment body. A mechanical arm is fixed to the top of the mounting frame. An installation plate is fixed to the output end of the mechanical arm. An electromagnet is fixed to the bottom of the installation plate.

One end of the removable adsorption net is engaged with the top of the fixing cylinder. The other end of the removable adsorption net is fixedly connected to one end of each of the multiple wire take-up assemblies by multiple steel wire ropes. The bottom of the removable adsorption net is also magnetically fixed to the top of the protective assembly by a magnet.

[0007] Preferably, a plurality of the take-up assemblies are arranged in a circumferential array on the top of the mounting plate. The plurality of take-up assemblies include two side plates and a take-up roller rotatably disposed between the two side plates. One end of the wire rope is wound around the surface of the take-up roller, and the other end of the wire rope passes through the surface of the mounting plate and is fixedly connected to the other end of the removable adsorption net. A motor for driving the take-up roller to rotate is also fixedly fixed to the outside of one of the side plates, and the output end of the motor passes through the surface of one of the side plates and is fixedly connected to one end of the take-up roller.

[0008] Preferably, the surface of the fixing cylinder has a plurality of grooves arranged in a circumferential array, the top of the fixing cylinder is fixedly connected to the bottom of the mounting plate, the top of the fixing cylinder is also fixed with a plurality of hooks arranged in a ring, the surface of the detachable adsorption net has a plurality of mesh holes, and the other end of the detachable adsorption net is fitted onto the surface of the plurality of hooks through the plurality of mesh holes.

[0009] Preferably, the magnet is ring-shaped, located inside the removable adsorption net, and the wire rope is located outside the removable adsorption net, and above the removable adsorption net.

[0010] The protective component includes a connecting column, the top of which is fixedly connected to the bottom of the fixed cylinder. An iron plate is fixed to the bottom of the connecting column, and a magnet is attracted to the top of the iron plate. A rubber pad for unloading protection is also provided at the bottom of the iron plate.

[0011] Preferably, the electromagnet includes a power supply body, an iron block, and a wire. The wire is made of copper. The power supply body is fixed to the top of the mounting plate. One end of the iron block is fixed to the center of the bottom of the mounting plate. The wire is wound around the surface of the iron block. Both ends of the wire pass through the surface of the mounting plate and extend into the power supply body. The two ends of the wire are respectively fixedly connected to the positive and negative terminals of the power supply body.

[0012] Preferably, the device body includes an operating table, the bottom of which is fixed with multiple casters, the top of which is fixed with a mounting box, and the two ends of which are respectively fixed with a sewage inlet and a sewage outlet.

[0013] Preferably, a control box body is also fixed to the top of the operating table. The control box body is located on one side of the mounting box, and a display screen is provided on the surface of the control box body.

[0014] Compared with related technologies, the adsorption-type wastewater treatment equipment provided by this utility model has the following beneficial effects:

[0015] 1. This utility model adopts a fixing system of top locking + steel wire rope traction + bottom magnetic attraction. One end of the detachable adsorption net is engaged with the top of the fixing cylinder using a dovetail groove structure to ensure that the net surface does not loosen under the impact of high-speed water flow. The other end of the detachable adsorption net is connected to the winding assembly through multiple steel wire ropes. In use, the winding assembly is first driven to wind up the steel wire ropes, causing the bottom of the detachable adsorption net to rise, which in turn lifts the metal residue on the surface of the detachable adsorption net. The detachable adsorption net then wraps around the surface of the metal residue. After wrapping, the power to the electromagnet is turned off, so that the metal residue is no longer attracted by the magnetic force of the electromagnet. Because the metal residue naturally settles to the bottom of the removable adsorption net due to gravity, it solves two problems. First, it solves the shortcomings of using a magnetic rod alone, where the metal residue is attracted by the magnetic rod and is not easy to remove. The mechanically driven winding assembly makes the storage of the removable adsorption net simple and time-saving, reducing the workload. Second, by first winding the wire rope with the winding assembly, the removable adsorption net wraps the surface of the metal residue, making it less likely to fall off due to vibration or water flow. Then, the power supply to the electromagnet is turned off, allowing the metal residue to fall to the bottom of the removable adsorption net, which facilitates the subsequent recycling of the metal residue.

[0016] 2. This utility model further enhances the connection stability between the removable adsorption net and the protective component by magnetically fixing the bottom of the removable adsorption net to the top of the protective component with a magnet. To a certain extent, even when the weight of the metal residue adsorbed by the removable adsorption net increases or the water flow rate changes suddenly, the surface of the removable adsorption net can be kept in a taut state, which facilitates sewage treatment operation.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figures 1 to 5 ,in, Figure 1 A schematic diagram of the overall structure of the adsorption-type wastewater treatment equipment provided by this utility model; Figure 2 This is a schematic diagram of the structure of a wastewater treatment facility; Figure 3 This is a cross-sectional structural diagram of a wastewater treatment facility; Figure 4 This is a schematic diagram of the fixed cylinder structure; Figure 5 This is a schematic diagram of the structure of an electromagnet.

[0025] In some embodiments, such as Figures 1 to 5 As shown, the device includes a main body and a mounting frame 3. The mounting frame 3 is located on one side of the main body. A robotic arm 31 is fixed to the top of the mounting frame 3. A mounting plate 32 is fixed to the output end of the robotic arm 31. An electromagnet is fixed to the bottom of the mounting plate 32. Multiple wire take-up assemblies are provided on the top of the mounting plate 32. A fixing cylinder 4 is sleeved on the outside of the electromagnet. A protective assembly is provided below the fixing cylinder 4. A removable adsorption net 6 is sleeved on the outside of the fixing cylinder 4. One end of the removable adsorption net 6 is engaged with the top of the fixing cylinder 4. The other end of the removable adsorption net 6 is fixedly connected to one end of multiple wire take-up assemblies by multiple steel wire ropes 52. The bottom of the removable adsorption net 6 is also magnetically fixed to the top of the protective assembly by a magnet 62.

[0026] Specifically, a fixing system is adopted, consisting of a top locking mechanism, steel wire rope 52 traction, and bottom magnetic attraction. One end of the detachable adsorption net 6 is engaged with the top of the fixing cylinder 4 using a dovetail groove structure to ensure that the net surface does not loosen under the impact of high-speed water flow. The other end of the detachable adsorption net 6 is connected to the take-up assembly via multiple steel wire ropes 52. In use, the take-up assembly is first driven to retract the steel wire ropes 52, causing the bottom of the detachable adsorption net 6 to rise, which in turn lifts the metal residue adsorbed on the surface of the detachable adsorption net 6. The detachable adsorption net 6 then wraps around the surface of the metal residue. After wrapping, the power to the electromagnet is turned off, so that the metal residue is no longer subject to the magnetic force of the electromagnet. The metal residue is naturally adsorbed and settles at the bottom of the removable adsorption net 6 due to gravity. On the one hand, this solves the disadvantage of using a magnetic rod alone, where the metal residue is not easy to remove due to the magnetic rod's attraction. The mechanically driven winding assembly makes the storage of the removable adsorption net 6 simple and time-saving, reducing the workload. On the other hand, by first winding the wire rope 52 with the winding assembly, the removable adsorption net 6 wraps the surface of the metal residue, making it less likely to fall off due to vibration or water flow. Then, the power supply to the electromagnet is turned off, allowing the metal residue to fall to the bottom of the removable adsorption net 6, which facilitates the subsequent recycling of the metal residue.

[0027] Furthermore, by magnetically fixing the bottom of the removable adsorption net 6 to the top of the protective component via magnet 62, the adsorption force of the electromagnet can be adjusted by changing the current in the electromagnet during use. This ensures that the use of the electromagnet and magnet 62 does not interfere with each other, further enhancing the connection stability between the removable adsorption net 6 and the protective component. To a certain extent, even when the weight of metal residue adsorbed by the removable adsorption net 6 increases or the water flow rate changes abruptly, the net surface of the removable adsorption net 6 can remain taut, facilitating wastewater treatment operations.

[0028] In some embodiments, reference is made to Figures 1 to 5 As shown, multiple take-up assemblies are arranged in a circumferential array on the top of the mounting plate 32. The multiple take-up assemblies include two side plates 5 and a take-up roller 51 rotatably disposed between the two side plates 5. One end of the wire rope 52 is wound around the surface of the take-up roller 51, and the other end of the wire rope 52 passes through the surface of the mounting plate 32 and is fixedly connected to the other end of the removable adsorption net 6. A motor 53 for driving the take-up roller 51 to rotate is also fixed on the outside of one of the side plates 5, and the output end of the motor 53 passes through the surface of one of the side plates 5 and is fixedly connected to one end of the take-up roller 51.

[0029] The surface of the fixed cylinder 4 is provided with a plurality of grooves 41 arranged in a circular array. The top of the fixed cylinder 4 is fixedly connected to the bottom of the mounting plate 32. The top of the fixed cylinder 4 is also fixed with a plurality of hooks 42 arranged in a ring. The surface of the removable adsorption net 6 has a plurality of mesh holes 61. The other end of the removable adsorption net 6 is fitted onto the surface of the plurality of hooks 42 through the plurality of mesh holes 61. The hooks 42 adopt a dovetail groove locking structure. One of the functions of the hooks 42 is to facilitate the replacement of the removable adsorption net 6.

[0030] Magnet 62 is ring-shaped and located inside the removable adsorption net 6. Steel wire rope 52 is located outside the removable adsorption net 6 and above the removable adsorption net 6.

[0031] The protective component includes a connecting post 43, which is made of plastic and is fixed by screws. The top of the connecting post 43 is fixedly connected to the bottom of the fixed cylinder 4. An iron plate 44 is fixed to the bottom of the connecting post 43. A magnet 62 is attracted to the top of the iron plate 44. The bottom of the iron plate 44 is also provided with a rubber pad 45 for unloading protection. The rubber pad 45 protects the bottom of the iron plate 44 and reduces damage caused by collision with other structures during use.

[0032] The electromagnet includes a power supply body 321, an iron block 322, and a wire 323. The wire 323 is made of copper. The power supply body 321 is fixed to the top of the mounting plate 32. One end of the iron block 322 is fixed to the center of the bottom of the mounting plate 32. The wire 323 is wound around the surface of the iron block 322. Both ends of the wire 323 pass through the surface of the mounting plate 32 and extend into the power supply body 321. The two ends of the wire 323 are fixedly connected to the positive and negative poles of the power supply body 321, respectively, to form an electromagnet structure. When energized, it generates a strong magnetic field and adsorbs magnetic pollutants in sewage, such as iron filings and iron oxide scale.

[0033] The main body of the equipment includes an operating table 1. Multiple casters 11 are fixed to the bottom of the operating table 1. The operating table 1 can be pushed when in use. A handle can be provided on one side of the operating table 1 for easy pushing or direct pushing of the surface of the operating table 1. An installation box 2 is fixed to the top of the operating table 1. A sewage inlet 21 and a sewage outlet 22 are fixed to the two ends of the operating table 1, respectively. A collection box 23 for collecting metal residues is also fixed to the top of the operating table 1. The collection box 23 is located on one side of the installation box 2.

[0034] The top of the control panel 1 is also fixed with a control box body 24, which is located on one side of the mounting box 2. The surface of the control box body 24 is also equipped with a display screen. The user inputs commands through the display screen interface, such as the movement trajectory of the robotic arm 31 and the gripping force. The signals are converted into digital signals by the internal circuit. The joint encoders and force sensors of the robotic arm 31 provide real-time feedback of position, speed, load and other data, forming the basis of closed-loop control. After the input signal is filtered, amplified and converted from analog to digital, it is logically calculated by a microprocessor, such as a PLC or industrial computer, to generate control commands. For example, after the user sets the target position of the robotic arm 31 through the display screen, the processor will combine the current joint angle data to calculate the angle and speed that each joint needs to rotate. The internal circuit or controller of the control box body 24 is used to control the movement of the robotic arm 31 and the motor 53. This is existing technology and will not be described in detail here.

[0035] For the electromagnet, its coil, i.e. the wire 323, is insulated by wrapping the coil with epoxy resin or silicone to prevent water from directly contacting the wire 323. In addition, its outer shell is sealed with a waterproof shell and IP68 protection for the internal circuit to ensure that water cannot penetrate. Epoxy resin or silicone has a sealing effect, but in actual use, epoxy resin or silicone will not affect the normal adsorption of the electromagnet and can still be used for sewage treatment.

[0036] Motor 53 is a waterproof motor, preferably a two-phase IP65 waterproof stepper motor.

[0037] Specifically, during use, wastewater enters the equipment body through inlet 21. The robotic arm drives the electromagnet, which generates a strong magnetic field to adsorb magnetic pollutants in the wastewater. Simultaneously, the removable adsorption net 6 intercepts non-magnetic suspended matter through mesh 61. One end of the removable adsorption net 6 is mechanically fixed by hook 42, and the other end is pulled by steel wire rope 52. The magnet 62 at the bottom of the removable adsorption net 6 is magnetically attached to the iron plate 44, ensuring that the removable adsorption net 6 does not loosen or fall off under the impact of high-speed water flow. When it is necessary to clean the metal residue on the surface of the removable adsorption net 6, the motor 53 first drives the take-up roller 51 to rotate, and the steel wire rope 52 retracts synchronously, thus removing the removable adsorption net 6. One end is raised to the top of the fixed cylinder 4, causing the bottom of the removable adsorption net 6 to rise, which in turn causes the metal residue adsorbed on the surface of the removable adsorption net 6 to rise. The removable adsorption net 6 is used to wrap the surface of the metal residue. After the wrapping is completed, the electromagnet is de-energized and the magnetic field disappears, so the metal residue is no longer attracted by the magnetic force of the electromagnet and naturally settles to the bottom of the removable adsorption net 6 due to gravity. The robotic arm 31 moves the electromagnet above the collection box 23 and moves the removable adsorption net 6 out of the sewage area. At this time, the reverse drive motor 53 lowers the other end of the removable adsorption net 6, and the metal residue falls into the collection box 23 below under the action of gravity for collection, which is convenient for subsequent recycling and processing.

[0038] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
