Specific embodiments

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0028] Refer to Figure 1 - Figure 6As shown in the figure, a wastewater treatment device of the present utility model includes a treatment tank 1. One side of the treatment tank 1 is connected and fixed to a flocculation tank 2 through a delivery pipe 4. A water pump 41 is provided on the delivery pipe 4. The top of the treatment tank 1 is fixedly connected with a tank cover 11. A water inlet pipe 12 is connected and fixed to the tank cover 11. A filter cylinder 3 is arranged in the treatment tank 1. Two slide rails 36 are fixedly connected to the bottom of the tank cover 11. The filter cylinder 3 is slidably connected to the slide rails 36. Two slide posts 381 are fixedly connected to the bottom of one of the slide rails 36. A limit block 38 is slidably connected to the two slide posts 381. Two limit posts 384 are fixedly connected to the top of the limit block 38. Two limit openings 37 are symmetrically formed on the filter cylinder 3. The limit posts 384 are inserted into the limit openings 37. Second springs 382 are sleeved on the outer sides of the slide posts 381. Two ends of each second spring 382 are respectively fixedly connected to the bottom of the limit block 38 and the inner side wall of the corresponding slide post 381. A pull block 383 is fixedly connected to the bottom of the limit block 38.

[0029] In the prior art, although the filter screen can filter wastewater, it cannot be disassembled and cleaned. After long-term use, floating substances, residues, etc. in the wastewater will accumulate and block the filter screen, affecting the filtering effect. During operation, wastewater is input into the treatment tank 1 through the water inlet pipe 12. The filter cylinder 3 in the treatment tank 1 preliminarily filters the wastewater. The filtered water enters the flocculation tank 2 through the delivery pipe 4 for flocculation treatment. After a period of time, the filter cylinder 3 accumulates more impurities and needs to be cleaned. Pull down the pull block 383. The pull block 383 drives the limit plate to move downward. The limit plate drives the limit posts 384 to move downward. The limit posts 384 leave the limit openings 37, releasing the fixation of the filter cylinder 3. Then, the filter cylinder 3 is removed from the slide rails 36 to achieve the function of quickly disassembling the filter cylinder 3, and then the filter cylinder 3 can be cleaned.

[0030] Furthermore, as Figure 3 shown, a rotating rod 31 is rotatably connected to the filter cylinder 3 through a bearing. Multiple thorn rods 35 are fixedly connected to the top end of the rotating rod 31. An impeller 32 is fixedly connected to the bottom of the rotating rod 31.

[0031] During operation, when the wastewater contains impurities such as hair, the hair is easily adsorbed on the inner wall of the pipeline, causing pipeline blockage. During wastewater treatment, after the wastewater is filtered by the filter cylinder 3 and flows out, when the water flow passes through the impeller 32, under the action of the water flow impact, the impeller 32 rotates. The impeller 32 drives the rotating rod 31 to rotate. The rotating rod 31 drives the thorn rods 35 to rotate. The thorn rods 35 rotate to wind and clean the hair-like impurities on the thorn rods 35.

[0032] Furthermore, as Figure 2 and Figure 3As shown, a lifting plate 34 is slidably connected to the rotating rod 31. The lifting plate 34 is slidably connected to the inner wall of the filter cylinder 3. A first spring 33 is fixedly connected to the bottom inner wall of the filter cylinder 3, and the top of the first spring 33 is fixedly connected to the bottom of the lifting plate 34.

[0033] During operation, after a period of time, impurities are adsorbed on the inner wall of the filter cylinder 3, and the filter cylinder 3 is blocked by the impurities, which will affect the filtration efficiency of the filter cylinder 3. The lifting plate 34 and the first spring 33 are provided. When wastewater flows into the filter cylinder 3, the lifting plate 34 is pressed, and the lifting plate 34 reciprocates up and down under the action of the first spring 33. During the movement of the lifting plate 34, the lifting plate 34 contacts the inner wall of the filter cylinder 3 and scrapes, cleaning the impurities on the inner wall of the filter cylinder 3.

[0034] Further, as Figure 2 and Figure 5 shown, a motor 23 is fixedly connected to the bottom of the flocculation tank 2. The output shaft of the motor 23 is rotatably connected to the bottom of the flocculation tank 2 through a bearing. A rotating rod 231 is fixedly connected to the output shaft of the motor 23, and a plurality of first stirring rods 232 are fixedly connected to the rotating rod 231; a feed hopper 21 is fixedly connected to the top of the flocculation tank 2 in a communicating manner, and a solenoid valve is installed on the feed hopper 21.

[0035] During operation, some impurities in the wastewater cannot be filtered and need to be treated with flocculants and neutralizing agents. The flocculants and neutralizing agents enter the flocculation tank 2 through the feed hopper 21, and then the motor 23 is started. The rotating rod 231 and the first stirring rods 232 are driven by the motor 23 to rotate, and the flocculants and neutralizing agents are quickly mixed into the wastewater by the first stirring rods 232 to perform flocculation treatment on the wastewater.

[0036] Further, as Figure 5 and Figure 6 shown, the bottom end of the rotating rod 231 is rotatably connected to a circular plate 244 through a bearing. The circular plate 244 is rotatably connected to the inner wall of the flocculation tank 2. A toothed ring 243 is fixedly connected to the bottom of the circular plate 244. A first gear 241 is fixedly connected to the outer side wall of the rotating rod 231. A second gear 242 is rotatably connected to the bottom inner wall of the flocculation tank 2 through a rotating shaft. One side of the second gear 242 meshes with the first gear 241, and the other side of the second gear 242 meshes with the toothed ring 243; two scraping rods 24 are symmetrically fixedly connected to both ends of the top of the circular plate 244. One side wall of each scraping rod 24 contacts the inner wall of the flocculation tank 2, and two second stirring rods 245 are fixedly connected to the other side wall of each scraping rod 24.

[0037] During operation, through the one-way stirring of the first stirring rod 232, the flocculant and the neutralizing agent are slowly fused, and it takes a long time to mix the flocculant and the neutralizing agent with the wastewater. By setting the first gear 241, the second gear 242 and the toothed ring 243, when the motor 23 is started, the motor 23 drives the rotating rod 231 to rotate. The rotating rod 231 drives the first stirring rod 232 and the first gear 241 to rotate. The first gear 241 drives the second gear 242 to rotate in the opposite direction. The second gear 242 drives the toothed ring 243 to rotate. The toothed ring 243 drives the round block to rotate. The round block drives the scraping rod 24 and the second stirring rod 245 to rotate. The rotating directions of the first stirring rod 232 and the second stirring rod 245 are opposite, quickly mixing the flocculant and the neutralizing agent with the wastewater for flocculation, and improving the efficiency of the flocculation treatment.

[0038] Furthermore, as Figure 5 shown, a drain pipe 22 is connected and fixedly installed on the side wall of the flocculation tank 2 away from the conveying pipe 4. A filter plate 221 is fixedly installed at one end of the drain pipe 22 close to the flocculation tank 2. A control valve is installed on the drain pipe 22.

[0039] During operation, the flocculated wastewater passes through the filter plate 221, filtering the flocs in the flocculation tank 2, and the flocculated water is discharged through the drain pipe 22 to the sedimentation tank for sedimentation.

[0040] Furthermore, as Figure 1 shown, a sewage discharge pipe 26 is connected and fixedly installed at the bottom end of the flocculation tank 2. The bottom of the sewage discharge pipe 26 is aligned with the round plate 244. A discharge valve is installed on the sewage discharge pipe 26.

[0041] During operation, the flocs filtered in the flocculation tank 2 are finally discharged through the sewage discharge pipe 26, and the opening and closing of the sewage discharge pipe 26 are controlled by the discharge valve.

[0042] Furthermore, as Figure 2 shown, a water level gauge 25 is fixedly installed on the inner wall of the top of the flocculation tank 2. The water level gauge 25 is electrically connected to the water pump 41.

[0043] During operation, by setting the water level gauge 25, it is convenient to control the opening and flow rate of the water pump 41, thereby controlling the water volume in the flocculation tank 2, and then adding an appropriate amount of flocculant and neutralizing agent.

[0044] Working principle: Wastewater is input into the treatment tank 1 through the water inlet pipe 12. The filter cartridge 3 in the treatment tank 1 preliminarily filters the wastewater. The filtered water enters the flocculation tank 2 through the delivery pipe 4 for flocculation treatment. After a period of time, the filter cartridge 3 accumulates more impurities and needs to be cleaned. Pull the pull block 383 downward. The pull block 383 drives the limit plate to move downward, and the limit plate drives the limit post 384 to move downward. The limit post 384 leaves the limit port 37, releasing the fixation of the filter cartridge 3. Then, the filter cartridge 3 is removed from the slide rail 36 to achieve the function of quickly disassembling the filter cartridge 3, and then the filter cartridge 3 can be cleaned.

[0045] When the wastewater contains impurities such as hair, the hair is easily adsorbed on the inner wall of the pipeline, resulting in pipeline blockage. During wastewater treatment, after the wastewater is filtered by the filter cartridge 3 and flows out, when the water flow passes through the impeller 32, the impeller 32 rotates under the action of the water flow impact. The impeller 32 drives the rotating rod 31 to rotate, and the rotating rod 31 drives the thorn rod 35 to rotate. The thorn rod 35 rotates to wind and clean the hair-like impurities on the thorn rod 35; after a period of time, impurities are adsorbed on the inner wall of the filter cartridge 3, and the impurities block the filter cartridge 3, which will affect the filtering efficiency of the filter cartridge 3. The lifting plate 34 and the first spring 33 are provided. When the wastewater flows into the filter cartridge 3, it presses the lifting plate 34, and the lifting plate 34 reciprocates up and down under the action of the first spring 33. During the movement of the lifting plate 34, the lifting plate 34 contacts the inner wall of the filter cartridge 3 and scrapes, cleaning the impurities on the inner wall of the filter cartridge 3.

[0046] By setting the first gear 241, the second gear 242 and the toothed ring 243, when the motor 23 is started, the motor 23 drives the rotating rod 231 to rotate. The rotating rod 231 drives the first stirring rod 232 and the first gear 241 to rotate. The first gear 241 drives the second gear 242 to rotate in the opposite direction. The second gear 242 drives the toothed ring 243 to rotate. The toothed ring 243 rotates to drive the round block to rotate. The round block drives the scraping rod 24 and the second stirring rod 245 to rotate. The first stirring rod 232 and the second stirring rod 245 rotate in opposite directions, quickly mixing the flocculant and the neutralizing agent with the wastewater for flocculation and improving the efficiency of the flocculation treatment.

[0047] Obviously, the above embodiments are merely examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
