Detailed implementation manners

[0021] 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 efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a belt filter press for sludge sewage treatment in a sewage treatment plant, including a body 1. Inside the body 1, a first conveying mechanism 2 and a second conveying mechanism 3 are respectively arranged. The first conveying mechanism 2 is located directly above the second conveying mechanism 3. On both sides of the body 1, an adjusting mechanism 4 is fixedly connected; among them, the adjusting mechanism 4 includes an L-shaped fixing plate 41 fixed to the side wall of the body 1. The surface of the L-shaped fixing plate 41 is fixedly connected with a cylinder 42. The output end of the cylinder 42 is fixedly connected with a connecting sleeve 43. The connecting sleeve 43 is used to control the distance adjustment of the second conveying mechanism 3. It is fixed to the side wall of the body 1 through the L-shaped fixing plate 41, and then driven by the cylinder 42, so that the connecting sleeve 43 can be adjusted up and down. When the connecting sleeve 43 adjusts the end of the second conveying mechanism 3 of the synchronous belt up and down, the distance between the gaps between the second conveying mechanism 3 and the first conveying mechanism 2 can be changed. Through the gap adjustment, the pressure values received by the sludge during conveying are all different.

[0023] According to Figure 1It can be seen that a cross bar 5 is fixedly connected to the top of the machine body 1, and a number of dispersing rods 6 are fixedly connected to the surface of the cross bar 5. The dispersing rods 6 are located directly above the conveying mechanism 1-2. Through the arrangement of a number of dispersing rods 6 fixed on the surface of the cross bar 5, when the sludge is placed on the conveying mechanism 1-2, the agglomerated sludge can be dispersed, so that it can be evenly spread on the conveying mechanism 1-2, preventing the agglomerated sludge from affecting the filter pressing effect.

[0024] According to Figure 3 It can be seen that the conveying mechanism 1-2 includes a driving roller 1-21, an auxiliary roller 1-22 and an adjusting roller 23 that rotate on the inner wall of the machine body 1 through bearings. The surfaces of the driving roller 1-21, the auxiliary roller 1-22 and the adjusting roller 23 are all rotatably connected with a conveying filter cloth 1-24. The side wall of the machine body 1 is rotatably connected to the end of the driving roller 1-21 through a driving part. Driven by the driving roller 1-21, it can drive the guide rail 44 to rotate. Under the rotation of the guide rail 44, the sludge on the surface is driven for conveying, and thus falls on the conveying mechanism 2-3 for filter pressing work. The auxiliary roller 1-22 and the adjusting roller 23 can assist in the stability of the rotation of the conveying filter cloth 1-24, and the adjusting roller 23 can change the tension of the conveying filter cloth 1-24.

[0025] According to Figure 3 It can be seen that the conveying mechanism 2-3 includes a driving roller 2-31 rotatably connected to the side wall of the machine body 1 through a driving part. The conveying mechanism 2-3 also includes an auxiliary roller 2-32 that rotates in the connecting sleeve 43 through a bearing. The surfaces of the driving roller 2-31 and the auxiliary roller 2-32 are rotatably connected with a feeding filter cloth 2-33. Driven by the driving roller 2-31, it can drive the feeding filter cloth 2-33 on the surface to move. Under the movement of the feeding filter cloth 2-33, the sludge on the surface can be conveyed, and thus contact filter pressing work is carried out between the feeding filter cloth 2-33 and the conveying filter cloth 1-24.

[0026] According to Figure 3 It can be seen that a sludge discharge port 7 is opened at the top of the machine body 1, and a sewage discharge pipe 8 is connected to the bottom of the machine body 1. The sludge discharge port 7 is located in front of the sewage discharge pipe 8. Through the arrangement of the sludge discharge port 7 and the sewage discharge pipe 8, the filtered sludge and sewage can be centrally discharged. Since the sludge discharge port 7 is located in front of the sewage discharge pipe 8, there will be no interference problem when discharging the sludge.

[0027] According to Figure 2 It can be seen that a guide rail 44 is fixedly connected to the side wall of the L-shaped fixing plate 41, and a connecting sleeve 43 is slidably connected to the surface of the guide rail 44. By sliding the connecting sleeve 43 on the surface of the guide rail 44, it can play an auxiliary guiding and positioning role when the connecting sleeve 43 is displaced.

[0028] Working principle of the utility model: During use, first, the machine body 1 is used to support the conveying mechanism 1 and the conveying mechanism 2. Then, the sludge to be processed is placed above the conveying mechanism 1. The conveying mechanism 1 can convey the sludge to the leftmost side. At this time, the sludge will fall above the conveying mechanism 2. Through the conveying of the conveying mechanism 2, the sludge can be conveyed to the middle position between the conveying mechanism 1 and the conveying mechanism 2. At this time, under the pressure between the conveying mechanism 1 and the conveying mechanism 2, the sludge is subjected to a pressure filtration operation to achieve solid-liquid separation. The separated sewage directly falls to the bottom of the machine body 1, while the sludge remains on the conveying mechanism 2 for conveying. Driven by the adjusting mechanism 4, the distance between the ends of the conveying mechanism 2 can be adjusted, thereby adjusting the distance between the conveying mechanism 1 and the conveying mechanism 2. By adjusting the distance, the magnitude of the pressure can be changed.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model.
