Description

Technical Field

[0001] This utility model relates to the field of coating wastewater treatment technology, and in particular to an integrated device for coating wastewater treatment. Background Technology

[0002] Coating wastewater refers to industrial wastewater generated during the coating process, mainly including wastewater from pretreatment, electrophoresis, and spray painting. Coating wastewater has a complex composition, often containing heavy metal ions (such as nickel and chromium), organic solvents, resin particles, suspended pigments, and magnetic metal impurities (such as iron filings). Existing integrated coating wastewater treatment devices suffer from the following drawbacks in the coagulation and mixing stage: insufficient separation of metal impurities; traditional processes require additional magnetic separation or filtration equipment to remove ferromagnetic impurities, increasing process complexity and floor space costs; and cleaning or replacing the mixing components requires shutdown and emptying of the water tank, resulting in low efficiency due to manual tank entry. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated device for treating coating wastewater.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An integrated device for treating coating wastewater includes a pretreatment tank. An installation platform is provided on the upper surface of the pretreatment tank. A sliding mechanism is horizontally arranged on the upper surface of the installation platform. An installation plate is vertically slidably fitted on the sliding mechanism. A stirring unit is provided on the installation plate. The stirring unit includes a motor, which is installed on the upper surface of the installation plate. The bottom output shaft of the motor extends to the bottom of the installation plate and is connected to the stirring mechanism. The stirring mechanism is used to stir the coating wastewater in the pretreatment tank. Multiple stirring plates are installed on the stirring mechanism.

[0006] In addition, a preferred structure is that a support frame is laterally arranged on the upper surface of the pretreatment pool on one side of the installation platform, and the support frame is used to support the installation plate.

[0007] Furthermore, in a preferred configuration, the sliding mechanism includes slide rails symmetrically arranged laterally on the upper surface of the mounting platform, sliders slidingly engaged on the slide rails on both sides, and slide rods vertically arranged at the four corners of the sliders, with the mounting plate vertically slidably engaged on the slide rods.

[0008] In addition, a preferred structure is that the mounting plate has handles symmetrically arranged on the surface above the slider, and mounting holes are opened on the upper surface of the mounting plate away from the handles.

[0009] In addition, a preferred structure is that the stirring mechanism includes a rotating shaft, a coupling is provided at the top of the rotating shaft for connecting to the output shaft at the bottom of the motor, connecting plates are symmetrically arranged on the upper and lower sides of the rotating shaft, and multiple through holes are evenly arranged on the connecting plates, with the stirring plate installed between the upper and lower connecting plates.

[0010] In addition, a preferred structure is that the stirring plate includes a magnetic plate body, and mounting heads are provided at the upper and lower ends of the magnetic plate body, the mounting heads being used for installation at the through holes.

[0011] The beneficial effects of this utility model are as follows: In this utility model, the stirring plate adopts a magnetic plate body, which directly adsorbs ferromagnetic metal particles such as iron filings and abrasive residues in the wastewater during the stirring process, eliminating the need for an independent magnetic separation process, reducing the load on the subsequent filtration system, and the stirring mechanism can be hoisted as a whole without stopping production by lifting the mounting plate with the handle. The magnetic plate body is fixed by the mounting head and the through hole, supporting modular disassembly, which facilitates offline cleaning of adsorbed impurities, avoids the risk of manual entry into the pool, and improves the cleaning efficiency.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-6 An integrated device for treating coating wastewater includes a pretreatment tank 01. An installation platform 1 is provided on the upper surface of the pretreatment tank 01. A sliding mechanism 5 is horizontally provided on the upper surface of the installation platform 1. An installation plate 2 is vertically slidably fitted on the sliding mechanism 5. A stirring unit 4 is provided on the installation plate 2. The stirring unit 4 includes a motor 41, which is installed on the upper surface of the installation plate 2. The bottom output shaft of the motor 41 extends to the bottom of the installation plate 2 and is connected to a stirring mechanism 42. The stirring mechanism 42 is used to stir the coating wastewater in the pretreatment tank 01. Multiple stirring plates 6 are installed on the stirring mechanism 42. The stirring plates 6 are used to adsorb metal impurities in the coating wastewater that can be magnetically adsorbed while stirring.

[0021] Furthermore, a deep treatment tank 02 is provided on one side of the pretreatment tank 01, and the deep treatment tank 02 is connected to the pretreatment tank 01 through a filtration system 03.

[0022] Among them, a support frame 3 is horizontally arranged on one side of the installation platform 1 on the upper surface of the pretreatment pool 01. The support frame 3 is used to support the installation plate 2. The support frame 3 plays a supporting role and, together with the installation hole 22, installs and fixes the components, which can fix the position of the installation plate 2.

[0023] In addition, the sliding mechanism 5 includes slide rails 51 that are symmetrically arranged on the upper surface of the mounting platform 1. Slider 52 is slidably fitted on the slide rails 51 on both sides. Slider rods 53 are vertically arranged at the four corners of the sliders 52. The mounting plate 2 is vertically slidably fitted on the slide rods 53, so as to realize the overall lateral movement of the stirring unit 4, which facilitates the quick switching of the position of the stirring unit 4, thereby facilitating the cleaning of the original stirring position in the pretreatment tank 01.

[0024] Furthermore, the mounting plate 2 is symmetrically provided with handles 21 on the surface above the slider 52, and the mounting plate 2 is provided with mounting holes 22 on the upper surface of the other end away from the handles 21. The handles 21 make it easy to lift the mounting plate 2, and the motor 41 is a small motor, with the overall weight of the stirring unit being less than 20kg.

[0025] Meanwhile, the stirring mechanism 42 includes a rotating shaft 422. The top of the rotating shaft 422 is provided with a coupling 421 for connecting to the bottom output shaft of the motor 41. The rotating shaft 422 is symmetrically provided with connecting plates 423 on its upper and lower sides. Multiple through holes 4231 are evenly arranged on the connecting plates 423. The stirring plate 6 is installed between the upper and lower connecting plates 423. The stirring plate 6 includes a magnetic plate body 61. The magnetic plate body 61 is provided with mounting heads 62 at its upper and lower ends. The mounting heads 62 are used to install at the through holes 4231.

[0026] In this embodiment, after the coating wastewater enters the pretreatment tank 01, it is stirred by the stirring unit 4, which mixes the coating wastewater with the coagulant and flocculant added to the pretreatment tank 01. This process removes colloids, fine suspended solids such as pigment particles, some heavy metals through co-precipitation, some emulsified oil, and some COD. At the same time, during the slow stirring process of the stirring plate 6, the stirring plate 6 can effectively magnetically attract most of the metal impurities that can be magnetically attracted. This also serves to filter small particulate impurities. Furthermore, when cleaning the impurities on the stirring plate 6 later, the fixing parts at the mounting hole 22 can be removed, and then the mounting plate 2 can be lifted directly to disassemble the stirring mechanism 42 for cleaning, without the need to enter the pretreatment tank 01 for replacement.

[0027] In this invention, the stirring plate 6 adopts a magnetic plate body 61, which directly adsorbs ferromagnetic metal particles such as iron filings and abrasive residues in the wastewater during the stirring process, eliminating the need for an independent magnetic separation process and reducing the load on the subsequent filtration system 03. The installation plate 2 can be lifted by the handle 21, allowing the stirring mechanism 42 to be hoisted as a whole without stopping production. The magnetic plate body 61 is fixed by the installation head 62 and the through hole 4231, supporting modular disassembly, facilitating offline cleaning of adsorbed impurities, avoiding the risk of manual entry into the pool, and improving cleaning efficiency.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
