[0024] Such as Figure 1 , Figure 2As shown in the figure, a sewage treatment device includes a sewage treatment tank 1. The upper surface of the sewage treatment tank 1 is fixedly connected with a water inlet 2, and the lower surface of the sewage treatment tank 1 is fixedly connected with a sewage outlet 6. Two crushing components 3 are fixedly installed in the upper part of the inner cavity of the sewage treatment tank 1. An auxiliary feeding component 4 is fixedly connected in the middle of the inner cavity of the sewage treatment tank 1, and the auxiliary feeding component 4 is located below the two crushing components 3. A filtering component 5 is fixedly connected in the lower part of the inner cavity of the sewage treatment tank 1, and the filtering component 5 is located below the auxiliary feeding component 4. Aggregate boxes 7 are clamped on the inner walls of the left and right parts of the sewage treatment tank 1, and the two aggregate boxes 7 are respectively located on the left and right sides of the filtering component 5;

[0025] Through the action of the water inlet 2, sewage enters the inner cavity of the sewage treatment tank 1. Then, under the action of the two crushing components 3, the garbage in the sewage is crushed. The crushed garbage and sewage move downward through the auxiliary feeding component 4. Then, under the action of the filtering component 5, the crushed garbage can be filtered and intercepted, and the filtered sewage is discharged through the sewage outlet 6. Among them, the intercepted garbage is concentrated into the inner cavities of the two aggregate boxes 7 under the action of the cleaning component inside the filtering component 5.

[0026] As Figure 3 shown in the figure, the crushing component 3 includes a motor 31. The front of the motor 31 is fixedly connected with the inner cavity of the front part of the sewage treatment tank 1, and the output end of the motor 31 is fixedly connected with a crushing roller 32. The outer walls of the front and rear parts of the crushing roller 32 are respectively rotationally connected with the inner cavity of the sewage treatment tank 1;

[0027] Through the action of the motor 31, the crushing roller 32 rotates, so as to be able to crush the garbage in the sewage.

[0028] The auxiliary feeding component 4 includes two first guide inclined plates 41. The opposite surfaces of the two first guide inclined plates 41 are respectively fixedly connected with the inner cavity of the sewage treatment tank 1. The opposite surfaces of the lower parts of the two first guide inclined plates 41 are both fixedly connected with a second guide inclined plate 43. A distribution plate 42 is fixedly connected in the inner cavity of the sewage treatment tank 1, and the distribution plate 42 is located between the two second guide inclined plates 43;

[0029] Through the action of the first guide inclined plate 41 and the second guide inclined plate 43, the sewage and garbage can be guided to the middle of the arc-shaped filter mesh plate 54. Then, through the action of the distribution plate 42, the sewage and garbage can be shunted, so as to reduce the impact force on the arc-shaped filter mesh plate 54 and facilitate the cleaning of the garbage at the same time.

[0030] As Figure 4As shown in the figure, gears 58 are fixedly connected to the front and rear sides of the fixed column 51. The upper surfaces of the outer walls of the two gears 58 are each engaged with a toothed plate 59. The outer walls of the two toothed plates 59 are respectively slidably connected to the inner cavity of the sewage treatment tank 1.

[0031] Through the action of the hydraulic rod 511, the connecting frame 510 can drive the toothed plate 59 to move, so that the gear 58 drives the fixed column 51 to rotate. Under the action of the fixed column 51, the connecting net plate 52 and the scraping plate 53 rotate, so as to push the garbage in the inner wall of the arc-shaped filter net plate 54 into the inner cavity of the aggregate box 7, which is convenient for cleaning.

[0032] As Figure 5 shown, the filtering assembly 5 includes a fixed column 51. The outer walls of the front and rear parts of the fixed column 51 are respectively rotatably connected to the inner cavity of the sewage treatment tank 1. The lower surface of the outer wall of the fixed column 51 is fixedly connected with a connecting net plate 52, and the fixed column 51 and the connecting net plate 52 are located directly below the material distribution plate 42.

[0033] Through the action of the scraping plate 53, the garbage intercepted on the inner wall of the arc-shaped filter net plate 54 can be pushed to one side. When the scraping plate 53 rotates above the support inclined plate 55, at this time, the scraping plate 53 and the support inclined plate 55 are on the same horizontal line. Under the action of the scraping plate 53 and the support inclined plate 55, the garbage can move into the inner cavity of the aggregate box 7. At this time, through the action of the fixed support plate 56 and the second guide inclined plate 43, the sewage above can flow downward through the arc-shaped limiting net plate 57 and the connecting net plate 52. Among them, through the action of the arc-shaped limiting net plate 57, the garbage in the sewage is intercepted on the inner wall of the arc-shaped limiting net plate 57. When the scraping plate 53 moves back to its original position, the garbage in the inner wall of the arc-shaped limiting net plate 57 falls into the inner wall of the arc-shaped filter net plate 54, which is convenient for cleaning the garbage without affecting the discharge of sewage.

[0034] The lower surface of the scraping plate 53 is lapped with an arc-shaped filter net plate 54. The lower surfaces of the left and right parts of the arc-shaped filter net plate 54 are respectively fixedly connected with support inclined plates 55. The lower surfaces of the two support inclined plates 55 are respectively fixedly connected to the inner cavity of the sewage treatment tank 1;

[0035] Through the action of the arc-shaped filter screen plate 54, the garbage in the sewage can be intercepted on the left and right sides of the scraper 53, and the two support inclined plates 55 can also play a role in guiding the material.

[0036] The working principle of the utility model: Through the action of the water inlet 2, the sewage enters the inner cavity of the sewage treatment tank 1, and then through the action of the motor 31, the crushing roller 32 rotates, so that the garbage in the sewage can be crushed. The crushed garbage and sewage move downward through the action of the first guide inclined plate 41 and the second guide inclined plate 43, and then under the action of the arc-shaped filter screen plate 54, the crushed garbage can be filtered and intercepted, and the filtered sewage is discharged through the sewage outlet 6. The intercepted garbage accumulates on the left and right sides of the scraper 53. At this time, through the action of the hydraulic rod 511, the connecting frame 510 can drive the toothed plate 59 to move, so that the gear 58 drives the fixed column 51 to rotate. Under the action of the fixed column 51, the connecting net plate 52 and the scraper 53 rotate, so as to push the garbage in the inner wall of the arc-shaped filter screen plate 54 into the inner cavity of the aggregate box 7. At this time, through the action of the fixed support plate 56 and the second guide inclined plate 43, the sewage above can flow downward through the arc-shaped limiting net plate 57 and the connecting net plate 52. Through the action of the arc-shaped limiting net plate 57, the garbage in the sewage is intercepted on the inner wall of the arc-shaped limiting net plate 57. When the scraper 53 moves back to its original position, the garbage in the inner wall of the arc-shaped limiting net plate 57 falls into the inner wall of the arc-shaped filter screen plate 54, which is convenient for cleaning the garbage without affecting the discharge of sewage.
