Description

Technical Field

[0001] The present application relates to the technical field of electrophoresis wastewater treatment devices, and specifically discloses an electrophoresis wastewater treatment device. Background Art

[0002] Electrophoretic wastewater is wastewater containing various pollutants generated during the electrophoretic coating process. The following is a detailed introduction to electrophoretic wastewater:

[0003] First, you need to know about electrophoretic coating. Electrophoretic coating is a technology that uses electric field to deposit organic matter or inorganic ions on the surface of conductive materials. It is widely used in the automotive, electronics, building materials and other industries.

[0004] Electrophoretic wastewater is generated because of electrophoretic coating;

[0005] · Common pollutants in electrophoresis wastewater include: organic pollutants: including water-soluble resins, pigments, fillers, etc. Inorganic pollutants: such as ammonia nitrogen, total phosphorus, total zinc and other heavy metal ions Physical indicators: such as suspended solids (SS), chemical oxygen demand (CODCr), etc.

[0006] · The treatment process includes:

[0007] Wastewater regulation: By setting up a regulating tank to buffer the flow changes of the reaction device during the operation of the batch treatment device, the stable operation of the wastewater treatment system is ensured.

[0008] Fenton catalytic oxidation: Use the strong oxidizing property of Fenton reagent to treat high-concentration pollutants, especially difficult-to-degrade organic matter.

[0009] Coagulation and sedimentation: By adding flocculants, the tiny particles in the wastewater are aggregated into larger flocs, which facilitate subsequent sedimentation and separation.

[0010] Activated carbon adsorption: Use the strong adsorption capacity of activated carbon to remove organic pollutants in wastewater.

[0011] Deep filtration: Filter media with varying pore sizes are used to further remove fine particles and colloids from wastewater. Heavy metal precipitation: Heavy metal ions are converted into insoluble precipitates by adding complexing agents or precipitants. Purification: Adsorption, membrane filtration, activated oxidation, and other methods are used to further enhance wastewater purification.

[0012] Water quality monitoring: Use chemical analysis methods or online monitoring instruments to test the treated water quality to ensure that it meets national emission standards;

[0013] There are currently problems with coagulation and sedimentation. Flocculants are added to make the tiny particles in the wastewater aggregate into larger flocs. Since it is a chemical reaction, the reaction is subject to external restrictions and the reaction efficiency fluctuates greatly, which will lead to lower coagulation and sedimentation efficiency. In view of this, the inventor proposed an electrophoresis sewage treatment device. Utility Model Content

[0014] The purpose of the utility model is to solve the problem of low reaction efficiency in the traditional electrophoresis sewage treatment device due to the use of chemical precipitation in the coagulation and sedimentation.

[0015] In order to achieve the above objectives, the present invention provides the following basic solutions:

[0016] The electrophoresis wastewater treatment device comprises a treatment box, a plurality of outflow pipes arranged at the bottom of the treatment box for outflow of treated wastewater, a connecting pipe arranged at the top of the treatment box, a top inlet, a bottom inlet and a filter assembly arranged on the connecting pipe;

[0017] A connecting bracket is provided inside the processing box, and the connecting bracket includes an inner bracket and an outer bracket. The inner bracket is fixed in the connecting pipe for receiving the filter assembly. The outer bracket is provided with a vibration assembly.

Its purpose is to accelerate the rate of coagulation and sedimentation, improve the time of the entire process, and solve the problem of low reaction efficiency of traditional electrophoresis sewage treatment devices due to the use of chemical precipitation in coagulation and sedimentation.

[0020] 2. Compared with the existing technology, this device adopts the principle of stirring and vibration to speed up the coagulation and sedimentation. Regarding stirring, the driving source of the motor is used to realize the rotation of the stirring rod, thereby accelerating the reaction between the flocculant and the sewage, and thus accelerating the rate of coagulation and sedimentation. On this basis, the mechanical vibration generated by the start-up of the motor is utilized and reasonably utilized to realize the vibration of the vibration chain. The vibration of the vibration chain can be fed back to the above reaction, and the vibration effect can accelerate the rate of coagulation and sedimentation.

[0021] 3. Compared with the existing technology, this device not only uses the principle of stirring and vibration to speed up the coagulation and sedimentation, but also makes reasonable improvements on the sewage entry, specifically in the inclined plate and the connecting rod used in conjunction with the stirring rod, to achieve dispersion of sewage when it enters. The sewage is no longer in a convergent state like traditional sewage, but enters in a dispersed state. The dispersed state of the sewage is used to initially react with the flocculant, which can increase the reaction rate of the flocculant.

[0023] Furthermore, the vibration assembly includes a plurality of connection points and a vibration chain with redundant length connected to the connection points. The free end of the vibration chain is provided with a fixed point, the fixed point is connected to the inner bottom of the processing box, and the connection point is set on the external bracket to achieve a stirring function and improve the reaction rate.

[0024] Furthermore, the connection point is located at the outermost end of the outer bracket, and the maximum outer diameter of the stirring assembly is smaller than the distance from the connection point to the center of the processing box, thereby avoiding motion interference, such that the stirring of the stirring assembly affects the vibration chain, and the vibration chain also avoids affecting the stirring of the stirring assembly.

[0025] Furthermore, the outer periphery of the mounting sleeve is provided with an external thread, and the connection between the outer bracket and the mounting sleeve is provided with an internal thread, and the external thread and the internal thread are threadedly connected to each other, thereby realizing a detachable connection of the mounting sleeve and facilitating installation and replacement of the mounting sleeve.

[0026] Furthermore, the stirring assembly includes a motor connected to the mounting sleeve, a rotating shaft coaxially connected to the motor output shaft, and stirring rods evenly arranged around the rotating shaft. The free end of the rotating shaft is rotatably connected to the processing box, and a rotating bearing is provided at the connection between the free end of the rotating shaft and the processing box.

[0027] Furthermore, the rotating bearing is a deep groove ball bearing, which is a commonly used bearing in the market, with high cost performance and easy availability.

[0028] Furthermore, the connecting rod is arranged on the stirring rod closest to the mounting sleeve, and the connecting rod and the stirring rod are in the same plane, so that the connecting rod can be used in conjunction with the stirring rod, and further the connecting rod can act on the sewage below the inclined plate, facilitating more thorough dispersion of the sewage.

[0029] Furthermore, the inclined plate is inclined downward toward the inner wall of the treatment box, so as to facilitate the downward diversion of sewage.

[0030] Furthermore, the top inlet is set at the top of the treatment box, and the bottom inlet is set at the bottom of the treatment box. Both the top inlet and the bottom inlet use electromagnetic switches. The top inlet is opened when sewage is added, and the bottom inlet is opened when sewage accumulates in the treatment box.
