DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a technical solution: Figure 2 and Figure 3As shown, in this embodiment, a high-concentration COD wastewater treatment device that is easy to operate includes a wastewater tank 1, which is characterized in that: a main stirring frame 2 is rotatably connected to the top inner wall of the wastewater tank 1, and a medicine supply component 4 is installed on the outside of the main stirring frame 2. The medicine supply component 4 includes a temporary storage chamber 401 fixedly sleeved on the rotating shaft of the main stirring frame 2, and a plurality of groups of nozzles 402 distributed at equal distances are arranged on the bottom outer wall of the temporary storage chamber 401. A rotating disk 403 is slidably sleeved on the circumferential outer wall of the main stirring frame 2, and the rotating disk 403 is rotatably connected to the circumferential inner wall of the temporary storage chamber 401. A connecting pipe 404 is fixedly inserted into the top outer wall of the rotating disk 403, and one end of the connecting pipe 404 passes through the top of the wastewater tank 1 and extends outward.

[0026] A medicine barrel 3 is fixedly installed at the bottom of the circumferential outer wall of the wastewater tank 1, a pump body 405 is fixedly installed at the bottom of the circumferential outer wall of the medicine barrel 3, and one end of the connecting pipe 404 is fixedly inserted in the water outlet of the pump body 405.

[0027] Start the pump body 405 outside the medicine barrel 3, and the pump body 405 can guide the treatment agent inside it into the connecting pipe 404, and then into the temporary storage chamber 401, and then spray downward from the multiple nozzles 402 at the bottom thereof, and the main stirring frame 2 will also drive the temporary storage chamber 401 and the multiple nozzles 402 to rotate synchronously, so that the treatment agent is evenly sprinkled on the surface of the wastewater. Since the rotating disk 403 rotates in the temporary storage chamber 401 and is fixedly connected to one end of the connecting pipe 404, it is ensured that the temporary storage chamber 401 can rotate normally and will not affect the normal liquid discharge.

[0028] like Figure 2 and Figure 4 As shown, a reinforcement component 5 is installed inside the wastewater tank 1 , and the reinforcement component 5 surrounds the outside of the main stirring frame 2 .

[0029] The reinforcing component 5 includes a plurality of auxiliary stirring frames 501 rotatably connected to the inner wall of the bottom of the wastewater tank 1, and the plurality of auxiliary stirring frames 501 are equidistantly distributed around the main stirring frame 2. A plurality of pulleys 502 are rotatably connected to the outer wall of the bottom of the wastewater tank 1, and the plurality of pulleys 502 are coaxially fixed to the plurality of auxiliary stirring frames 501, respectively. The plurality of pulleys 502 are sleeved with the same belt 503. A second motor 504 is fixedly installed on the outer wall of the bottom of the wastewater tank 1, and the rotating shaft of the second motor 504 is coaxially fixed to one of the pulleys 502.

[0030] Start the motor 2 504 at the bottom of the wastewater tank 1. The shaft of the motor 2 504 drives a pulley 502 to rotate. The pulley 502 drives several other pulleys 502 to rotate simultaneously through the belt 503. Then, multiple auxiliary stirring frames 501 will be rotated synchronously by multiple pulleys 502, which can effectively improve the mixing efficiency by cooperating with the main stirring frame 2.

[0031] like Figure 2As shown, the belt 503 is a toothed belt, and the plurality of pulleys 502 are matched with the belt 503 so that the friction between the two is large enough to avoid the problem of slipping during the transmission process.

[0032] like Figure 1 As shown in FIG. 2 , the spiral blades of the main stirring frame 2 and the auxiliary stirring frame 501 have opposite rotation directions, so that the wastewater is driven to form convection, which is beneficial to increase the mixing efficiency of the wastewater and the treatment liquid.

[0033] like Figure 2 and Figure 3 As shown, the multiple groups of nozzles 402 at the bottom of the temporary storage chamber 401 are all inclined, and the inclination angles of each group of nozzles 402 are different, so that the treatment liquid sprayed by each group of nozzles 402 has a different landing point, further increasing the spraying area. There is no limit to the number of nozzles 402 in a group, which depends on the diameter of the wastewater tank 1.

[0034] like Figure 1 As shown, a motor 6 is fixedly installed on the outer wall of the top of the wastewater tank 1, and the rotating shaft of the motor 6 is coaxially fixed with the top of the main stirring frame 2. When the motor 6 on the top of the wastewater tank 1 is started, the rotating shaft of the motor 6 will drive the main stirring frame 2 to rotate, and the wastewater can be started to be stirred.

[0035] The utility model provides a high-concentration COD wastewater treatment device that is easy to operate, and the specific working principle is as follows:

[0036] When the device is working, the COD wastewater is introduced into the wastewater tank 1, and the motor 6 on the top of the wastewater tank 1 is started. The motor 6 shaft will drive the main stirring frame 2 to rotate, and the wastewater can be stirred. During this period, the pump body 405 outside the medicine barrel 3 is started at the same time. The pump body 405 can introduce the treatment agent inside into the connecting pipe 404, and then enter the temporary storage chamber 401, and then spray downward from the multiple nozzles 402 at the bottom thereof, and the main stirring frame 2 will also drive the temporary storage chamber 401 and the multiple nozzles 402 to rotate synchronously, so that the treatment agent is evenly sprinkled on the temporary storage chamber 401. On the surface of the wastewater, since the rotating disk 403 rotates in the temporary storage chamber 401 and is fixedly connected to one end of the connecting pipe 404, it is ensured that the temporary storage chamber 401 can rotate normally and will not affect the normal liquid discharge. Then, the motor 2 504 at the bottom of the wastewater tank 1 is started, and the shaft of the motor 2 504 drives a pulley 502 to rotate. This pulley 502 drives several other pulleys 502 to rotate at the same time through the belt 503, and then the multiple auxiliary stirring frames 501 will be rotated synchronously by the multiple pulleys 502, which can effectively improve the mixing efficiency by cooperating with the main stirring frame 2.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
