DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: a sludge cutter for sewage treatment that is easy to adjust, including a housing 1, a motor 2, a filter screen 3, a pressing plate 4, an air cylinder 5, a rotating rod 6, a spring 7, a limiting rod 8, a cutter 9, a feed inlet 10, a flow sensor 11, a solenoid valve 12, a feeding pipe 13, an additive tank 14, a sludge outlet pipe 15, and a water outlet pipe 16.

[0029] Embodiment 1

[0030] The sludge cutter for sewage treatment that is easy to adjust is provided with an automatic feeding structure, which can add additives while introducing sewage. Specifically:

[0031] The housing 1 is also connected with an automatic feeding structure. The automatic feeding structure can open the solenoid valve 12 to add additives for sewage treatment while discharging sewage. The automatic feeding structure includes a feeding port 10. The feeding port 10 penetrates through the side surface of the housing 1 and is connected to the filter screen 3 in a through manner. A flow sensor 11 is connected to the outer surface of the feeding port 10. A feeding pipe 13 is connected to the upper surface of the feeding port 10 in a through manner, and a solenoid valve 12 is arranged at the lower end of the feeding pipe 13. A sludge discharge pipe 15 penetrates through the side surface of the housing 1 and is connected to the filter screen 3 in a through manner. A water discharge pipe 16 is connected to the side surface of the housing 1 in a through manner;

[0032] When the sludge cutter for sewage treatment that is easy to adjust is in use, as Figure 3 shown, first, connect the sewage pipe to the feeding port 10, and then make the sewage directly enter the interior of the filter screen 3 through the feeding port 10. When the sewage flows through the feeding port 10, the flow sensor 11 will be induced, and then the flow sensor 11 will open the solenoid valve 12. Connect to the feeding pipe 13 through the solenoid valve 12. Since the upper end of the feeding pipe 13 is connected to the additive tank 14, when the solenoid valve 12 is opened, the additives in the additive tank 14 will enter the feeding port 10 through the feeding pipe 13. As the sewage enters the filter screen 3, the mud and water can be separated through the filter screen 3. The water will pass through the filter screen 3 and enter the interior of the housing 1, and then be discharged through the water discharge pipe 16 connected to the side surface of the housing 1.

[0033] Embodiment 2

[0034] The sludge cutter for sewage treatment that is easy to adjust is also provided with an adjustable distance cutting structure, which can change the distance between the cutting knives 9 driven by the pressing plate 4 to make the cutting effect better. Specifically:

[0035] A motor 2 is fixedly installed on the upper surface of the housing 1. It also includes a filter screen 3 which is fixedly installed on the bottom surface of the inner wall of the housing 1. An adjustable-distance cutting structure is arranged inside the housing 1. The adjustable-distance cutting structure can change the distance between the cutting blades 9 by controlling the downward movement of the pressing plate 4. The adjustable-distance cutting structure includes a pressing plate 4 which is slidably installed inside the filter screen 3. The upper surface of the pressing plate 4 is fixedly connected to the push rod of a cylinder 5, and the cylinder 5 is fixedly installed on the upper surface of the housing 1. The lower end of the motor 2 is fixedly connected to a rotating rod 6. The lower end of the rotating rod 6 is rotatably installed on the bottom surface of the inner wall of the housing 1. A plurality of cutting blades 9 are slidably installed on the outer surface of the rotating rod 6. Springs 7 are fixedly connected between the cutting blades 9. A limiting rod 8 is fixedly installed on the upper surface of the cutting blade 9. The upper end of the limiting rod 8 slidably penetrates through the corresponding cutting blade 9 above. The positions of the limiting rods 8 connected to the other cutting blades 9 corresponding to the cutting blades 9 up and down are staggered. The lower surface of the pressing plate 4 is rotatably connected to the uppermost cutting blade 9;

[0036] After the sewage enters the inside of the filter screen 3, the cylinder 5 is activated. As Figure 3 shown, the cylinder 5 will cause the pressing plate 4 to move downward. Since the pressing plate 4 is slidably connected to the rotating rod 6 and the lower surface of the pressing plate 4 is rotatably connected to the uppermost cutting blade 9, the pressing plate 4 will press the cutting blade 9 downward. At the same time, the sewage inside the filter screen 3 will be squeezed, causing the water flow to quickly drain out of the filter screen 3. Then when the cutting blade 9 is pressed, it will slide on the outer surface of the rotating rod 6. And since springs 7 are fixedly connected between the cutting blades 9, the springs 7 will be squeezed. Then the limiting rod 8 fixedly installed on the upper surface of the cutting blade 9 will slidably penetrate through the corresponding cutting blade 9 above. Since the positions of the limiting rods 8 connected to the other cutting blades 9 corresponding to the cutting blades 9 up and down are staggered, the sliding of the limiting rod 8 through the cutting blade 9 above will not affect the other cutting blades 9. And through the limiting rod 8, the cutting blades 9 can rotate simultaneously. After the pressing plate 4 moves downward to an appropriate distance, the motor 2 will be activated. The motor 2 will drive the cutting blades 9 to rotate, causing the cutting blades 9 to cut and break the fibers in the sludge in the filter screen 3. After cutting for a period of time, the pressing plate 4 can be made to press downward again according to the need, reducing the distance between the cutting blades 9 again and cutting again to make the cutting effect better. Finally, the sludge is discharged through the sludge discharge pipe 15 connected to the surface of the filter screen 3.

[0037] Working principle: When using this sludge cutter for sewage treatment that is easy to adjust, an automatic feeding structure is provided. Through the water inlet 10, additives can be added while the sewage enters for subsequent treatment. An adjustable-distance cutting structure is also provided, which can drive the cutting blades 9 to adjust the distance through the pressing plate 4, increasing the overall practicality.

[0038] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
