DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples.

[0027] In one embodiment, as shown in Figures 1-5 A chromium series wastewater treatment device convenient to clean, comprising a processing tank 100, a stirring assembly 200, a driving assembly 300, and an ultrasonic cleaning mechanism 400, wherein the processing tank 100 is a reaction tank body of the wastewater treatment device, the processing tank 100 is provided with a water adding hole 101 and a material adding hole 102 on the top surface, the processing tank 100 is provided with a water outlet 103 at the lower end of the side surface, and the processing tank 100 is fixedly provided with a supporting leg 104 on the bottom surface; during wastewater treatment, wastewater is added into the processing tank 100 through the water adding hole 101, then an additive is added through the material adding hole 102, so that the additive reacts with the wastewater, and finally the treated wastewater is discharged through the water outlet 103.

[0028] In the embodiment, the stirring assembly 200 and the driving assembly 300 are installed at the middle position of the top surface of the processing tank 100, and the ultrasonic cleaning mechanism 400 is installed at the middle position of the bottom surface of the processing tank 100; the stirring assembly 200 is driven to rotate by the driving assembly 300, so that the wastewater is stirred, and the reaction of the wastewater and the additive is more sufficient; after the wastewater treatment is completed, the processing tank 100 is cleaned by the ultrasonic cleaning mechanism 400.

[0029] In one embodiment, as shown in Figure 5As shown, the stirring assembly 200 includes a stirring rod 201. The upper end of the stirring rod 201 has two symmetrical protrusions 202. The body of the stirring rod 201 has a placement groove 203 for placing the stirring blade 204. The stirring blade 204 is rotatably connected to a fixed shaft 206 located at the upper end of the placement groove 203 via a connecting plate 205 at the upper end. The lower end of the stirring blade 204 is provided with a counterweight 207. The top end of the stirring rod 201 is provided with a handle 208. When the stirring rod 201 rotates, the stirring blade 204 leaves the placement groove 203 under the action of centrifugal force and rotates with the stirring rod 201, thereby achieving the effect of stirring the wastewater. After the stirring rod 201 stops rotating, the stirring blade 204 will return to the placement groove 203 under the action of gravity of the counterweight 207.

[0030] In one embodiment, such as Figure 3 As shown, the drive assembly 300 drives the stirring assembly 200 to rotate. The drive assembly 300 includes a motor 301, a first gear 303, and a second gear 304. The motor 301 is located on one side of the stirring assembly 200. The first gear 303 is fixed to the lower end of the motor 301. The second gear 304 meshes with the first gear 303. A connecting cylinder is fixed to the lower end of the second gear 304. The connecting cylinder is connected to the top plate of the processing tank 100 through a bearing. In use, the motor 301 drives the first gear 303 to rotate, and the first gear 303 drives the second gear 304.

[0031] In one embodiment, such as Figure 3 As shown, the motor 301 is fixed to the top surface of the processing tank 100 by a fixed bracket 302. The fixed bracket 302 includes a vertical pole and a T-shaped crossbeam, and the bottom end of the motor 301 is fixed on the T-shaped crossbeam.

[0032] In one embodiment, such as Figure 3 As shown, the second gear 304 has two symmetrical grooves, which correspond to the protrusions 202 on the upper end of the stirring rod 201. The second gear 304 has a protective cover 305 on the side near the water inlet 101. The protective cover 305 is composed of two semi-circular ring plates. When the stirring assembly 200 is installed, the stirring rod 201 is vertically inserted into the second gear 304 so that the protrusions 202 on the stirring rod 201 are aligned with the grooves on the second gear 304, so that the second gear 304 can drive the stirring rod 201 to rotate when it rotates.

[0033] In one embodiment, such as Figure 2 As shown, the ultrasonic cleaning mechanism 400 includes an ultrasonic generator, which is fixed to the bottom surface of the treatment tank 100. The ultrasonic generator emits ultrasonic waves, and the vibration of the ultrasonic waves breaks the adhesion between the dirt and the inner surface of the treatment tank 100, thereby achieving the cleaning effect.

[0034] In one embodiment, such as Figure 4As shown, the bottom surface of the inner cavity of the treatment tank 100 is in a slope structure, and the lowest point of the slope is at the same height as the water outlet, so that the cleaned dirt is more easily discharged and is not easily left in the treatment tank 100.

[0035] In one embodiment, as shown in the drawings, the side wall of the treatment tank 100 is provided with a controller 500, and the ultrasonic generator and the motor 301 are electrically connected to the controller 500. In use, the ultrasonic generator and the motor 301 are controlled by the controller 500. Figure 1

[0036] The above embodiment discloses a chromium wastewater treatment device which is convenient to clean. In wastewater treatment, wastewater is added into the treatment tank 100 through the water inlet 101, and then the additive is added through the feeding port 102 to make the additive react with the wastewater. At the same time, the motor 301 is started, the first gear 303 on the motor 301 drives the second gear 304 to rotate, thereby driving the stirring assembly 200 to rotate to stir the wastewater and accelerate the reaction rate of the additive and the wastewater. After the reaction is completed, the treated wastewater is discharged from the water outlet 103. In cleaning the treatment tank 100, water and a cleaning agent are added into the treatment tank, and then the ultrasonic generator is started to clean. After cleaning is completed, the wastewater is discharged from the water outlet 103.

[0037] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.​
