Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a device for removing heavy metals from wastewater. Background Art

[0002] Heavy metal pollution in wastewater is a serious environmental problem. For the removal of heavy metals in wastewater, precipitation, adsorption, membrane separation or electrochemical methods can be used to treat heavy metals in wastewater. Heavy metals in wastewater refer to metal elements in the water that exceed the environmental standard limit. Heavy metals are often produced in industrial production and waste treatment processes, and have potential hazards to the environment and human health. Wastewater heavy metal removal equipment is mainly used to treat wastewater containing high concentrations of heavy metals. These equipment use different technologies and processes to remove or reduce heavy metals in wastewater to meet emission standards or reuse requirements.

[0003] According to the publication number: CN213865718U, a heavy metal removal device for mine wastewater includes a centrifugal device, a pre-filtering level and a control device. A water inlet is installed on one side of the centrifugal device, and a water outlet is installed on the other side of the centrifugal device. The bottom of the water inlet is penetrated by a pre-filtering level, and a bottom plate is installed at the front end of the pre-filtering level. A rectangular trash basket is installed above the bottom plate. A motor is installed at the bottom of the centrifugal device, and a control device is installed on the inner wall of the centrifugal device. A storage box is installed inside the control device, and a high-concentration alkaline solution is installed inside the storage box, which can react with heavy metal ions in sewage to form solid particles and finally be filtered; however, the existing removal equipment still has the following defects in actual use:

[0004] 1. When the removal equipment uses the sedimentation method to treat heavy metals in wastewater, chemical agents are added to precipitate the heavy metals in the form of sediment, which will produce a large amount of sediment. The large amount of sediment will cause the isolation filter to become clogged, making the treatment of heavy metals in wastewater slow and inefficient, and the treatment efficiency is difficult to guarantee.

[0005] 2. Existing heavy metal removal equipment adds chemical agents inside, waits for the mixing of the agents and wastewater, and precipitates the heavy metals in the wastewater. However, this treatment method is not convenient for fully mixing the chemical agents and heavy metal wastewater, resulting in the need to add more chemical agents for precipitation operations, resulting in a waste of chemical agents, increasing the cost of treating heavy metals in wastewater, and is not convenient for mixing chemical agents and heavy metal wastewater. Utility Model Content

[0006] The purpose of the utility model is to provide a device for removing heavy metals from wastewater, so as to solve the problems of the existing removal devices in the use process proposed in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A device for removing heavy metal from wastewater, comprising:

[0009] A protective housing, which is the main body of the novel removal device;

[0010] A medicine pump, which is installed on one side of the protective shell;

[0040] A controller, which is arranged on a side of the protective shell;

[0042] The embodiment of the utility model provides a wastewater heavy metal removal device, which has the following beneficial effects: the sediment is isolated by a sediment filter, and then the sediment is moved and transported to the inside of a sediment cleaning sealing door for storage through the rotation of a spiral filter salvage net. The cleaned and isolated heavy metal sediment can improve the operating efficiency of the wastewater treatment equipment, reduce the blockage and obstruction of the sediment, and the chemical agents are fully mixed and precipitated through the rotation of the stirring blades, thereby avoiding the need to increase the chemical agents for precipitation operations and facilitating the mixing of the chemical agents and heavy metal wastewater.

Then the controller controls the medicine pump to extract the medicine inside the medicine storage tank, and transports the medicine to the connected nozzle to discharge the medicine to the bottom of the filter plate, so that the medicine is mixed with the wastewater passing through the filter plate. Then the controller drives the first motor to rotate the connected first rotating column to drive the connected stirring blade to rotate, and the internal mixture is stirred by the rotation of the stirring blade to be fully mixed, so that the chemical agent can be fully mixed and precipitated, avoiding the need to increase the chemical agent for precipitation operation, and facilitating the mixing of the chemical agent and the heavy metal wastewater.

[0051] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] Example: Figure 1 As shown, a wastewater heavy metal removal device comprises: a protective shell 1 is used for treating the main box structure of the heavy metal in the wastewater, and a treatment mechanism is installed and supported and connected; the wastewater that needs to remove the heavy metal is input through the wastewater input pipe 4 on the top, which is used to input the wastewater into the equipment for pretreatment; the controller 2 is used to monitor and control the operation status of the equipment to ensure the stable and efficient operation of the equipment and control the electrically connected power consumption mechanism; the output pipe 8 is used to output the discharge interface of the transmission medicine water pump; the sediment cleaning sealing door 3 and the filter cleaning sealing door 5 are provided with handles on the surface for more convenient opening; the interior of the sediment cleaning sealing door 3 is used to temporarily store the sediment transported by the spiral filtering salvage net 20; the sediment cleaning sealing door 3 is opened to clean the sediment accumulated inside; the filter cleaning sealing door 5 is opened to clean the debris filtered out by the filter plate 17.

[0054] like Figure 3As shown, it includes: a chemical pump 7 is used as a power source for extracting chemicals when the controller 2 is controlled, the chemicals are extracted through an interface connected to an input pipe 9, the extracted chemicals are discharged through an output pipe 8 on the top, and are transported to a connected nozzle 10 through a connecting pipe 6 and discharged to the inside for mixing operations, which are used for spraying chemicals, and the rotational force of the first motor 14 is used to rotate the connected stirring blades 16 through a first rotating column 15. The rotation of the stirring blades 16 allows the chemicals to be fully mixed and precipitated, thereby avoiding the need to add chemicals for precipitation operations and facilitating the mixing of chemicals and heavy metal wastewater. The treated wastewater output pipe 21 is used to discharge the treated wastewater.

[0055] like Figure 4 As shown, it includes: the second rotating column 19 is rotated by the rotation of the second motor 18, and the rotating force is transmitted to the connected spiral filtering salvaging net 20, and the sediment isolated by the sediment filter 22 is transported through the rotation of the spiral filtering salvaging net 20, and the sediment is transported to the inside of the sediment cleaning sealing door 3 for storage, and the sediment filter 22 is used to isolate the sediment to prevent the sediment from being discharged from the equipment by itself through the sediment filter 22, causing unnecessary trouble.
