[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1-4 An industrial wastewater purification and treatment device is provided, which includes a frame 1.

[0027] Feed homogenization and filtration unit 2 is installed on the frame 1. The feed homogenization and filtration unit 2 is equipped with alternating porous flow dividers 201 and buffer baffles 202. The feed homogenization and filtration unit 2 is also equipped with a stepped filter screen, which is located below the buffer baffles 202. In application, the alternating arrangement of the porous flow dividers 201 and the buffer baffles 202 achieves water flow homogenization and flow velocity buffering, reducing turbulent impact. At the same time, the stepped filter screen intercepts large particles of impurities in stages, reducing the load on subsequent treatment.

[0028] The vortex centrifugal separation mechanism includes a conical vortex cavity 401 mounted on a frame 1. The conical vortex cavity 401 is connected to the feed homogenization and filtration unit 2 via a connecting pipe 3. The conical vortex cavity 401 contains a centrifugal disc 402, which is driven by a drive component. In application, the conical vortex cavity 401 and the centrifugal disc 402 rotate to generate strong centrifugal force, which efficiently separates suspended solids (such as metal particles) with high density in wastewater. Physical separation reduces reliance on chemical agents.

[0029] Release pipe 5 is installed on the conical vortex cavity 401 and the conical vortex cavity 401 is connected to release pipe 5 so as to directly output the purified water and simplify the process.

[0030] Reference Figure 2 and Figure 4 The stepped filter screen includes an upper filter screen 203, a middle filter screen 204, and a lower filter screen 205. The upper filter screen 203, the middle filter screen 204, and the lower filter screen 205 are arranged sequentially along the water flow direction. The pore sizes of the upper filter screen 203, the middle filter screen 204, and the lower filter screen 205 are 100 mesh, 300 mesh, and 500 mesh, respectively. In application, through the stepped filter screen's graded design, the upper filter screen 203 (100 mesh) intercepts coarse particles (such as gravel), the middle filter screen 204 (300 mesh) captures medium suspended solids (such as fibers), and the lower filter screen 205 (500 mesh) filters out micron-sized fine particles (such as colloids). This achieves step-by-step filtration, avoids mesh clogging, extends equipment life, and improves the removal rate of micron-sized pollutants.

[0031] Reference Figure 3 and Figure 4 The conical vortex cavity 401 has a tangential inlet on its side wall. The tangential inlet is connected to the end of the connecting pipe 3 away from the feed homogenization filter unit 2. A heavy metal collection hopper 403 is installed at the bottom of the conical vortex cavity 401. In application, the tangential inlet allows wastewater to enter the conical vortex cavity 401 along the tangential direction, which enhances the vortex centrifugation effect and improves the separation efficiency. At the same time, the heavy metal collection hopper 403 can directly collect the settled high-density heavy metal sludge, which is convenient for centralized treatment and reduces secondary pollution.

[0032] Reference Figure 3 and Figure 4 The centrifuge disc 402 has an inverted umbrella-shaped structure. The surface of the centrifuge disc 402 is provided with several guide channels 4021, which are arranged in a circumferential array at equal intervals. The depth of the guide channels 4021 gradually decreases from the center to the edge, and the tilt angle of the guide channels 4021 is 15-30°. In application, the circumferential array design of the guide channels 4021 uniformly disperses the water flow. The channel depth decreases from the center to the edge (tilt angle 15-30°), forming a gradient centrifugal force field, which accelerates the sedimentation of particles. The inverted umbrella-shaped centrifuge disc 402 and the guide channels 4021 work together to optimize fluid dynamics, reduce energy consumption, and improve the separation accuracy of fine particles.

[0033] Reference Figure 1 , Figure 3 as well as Figure 4The driving component includes a drive shaft 405 that is vertically and rotatably mounted on the bottom of the conical vortex cavity 401. A drive motor 404 is mounted on the frame 1. The output shaft of the drive motor 404 is connected to one end of the drive shaft 405. The end of the drive shaft 405 away from the drive motor 404 is connected to the centrifugal disc 402. The heavy metal collection hopper 403 is rotatably mounted on the outer surface of the drive shaft 405. In application, the drive motor 404 directly drives the centrifugal disc 402 through the drive shaft 405, which is highly efficient in power transmission. The heavy metal collection hopper 403 is rotatably connected to the drive shaft 405, so that separation and collection are carried out simultaneously, reducing the frequency of downtime for cleaning.

[0034] The working principle of this utility model is as follows: Wastewater is injected into the feeding homogenization and filtration unit 2. At this time, the water flow is dispersed by the porous diversion plate 201, and the impact force is reduced by the buffer baffle plate 202 to form a stable laminar flow. At the same time, the upper filter screen 203 intercepts particles, the middle filter screen 204 captures suspended solids, and the lower filter screen 205 intercepts colloidal particles. Then, the pre-filtered wastewater is injected tangentially into the conical vortex cavity 401 through the connecting pipe 3, and the drive motor 404 is started. At this time, the output shaft of the drive motor 404 drives the drive shaft 405 to rotate, and the drive shaft 405 drives the centrifugal disk 402 to rotate. Under the action of the guide groove 4021 on the centrifugal disk 402, a high-speed vortex is formed. At the same time, the centrifugal force pushes the heavy metal particles (density > 2.5g / cm³) 3 The wastewater is thrown against the cavity wall and settles into the heavy metal collection hopper 403, while the light water rises and is discharged from the release pipe 5, thus completing the purification of industrial wastewater.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
