Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge thickening equipment, specifically a sludge thickening equipment for ecological treatment of water conservancy and river channels. Background Technology
[0002] A belt sludge thickener is a commonly used, continuously operating sludge thickening machine. It pumps water-containing sludge to a sludge mixing tank, where flocculants are added to ensure thorough mixing and reaction. The flocculant is a high-molecular polymer. The sludge then flows into the sludge distributor of the belt sludge filter press, where it is evenly distributed onto the gravity dewatering zone. Under the bidirectional guidance of the sludge rake and the action of gravity, the sludge rapidly loses its free water as the dewatering filter belt moves.
[0003] Since river sludge often contains sand and gravel, which can damage the dewatering filter belt and seriously affect the dewatering effect, a device is needed to remove the sand and gravel before the sludge is concentrated. Utility Model Content
[0004] The sludge thickening equipment for ecological treatment of water conservancy and river channels includes a sand and gravel cleaning machine and a belt sludge thickener. The sand and gravel cleaning machine includes a housing and a rotating cage. The housing is equipped with an inlet pipe, a motor support, an outlet pipe, and a rotating cage fixing groove. The motor support is equipped with a motor and a gear. The outlet pipe is equipped with a water pump connected to the belt sludge thickener. The rotating cage fixing groove includes an inner ring and an outer ring. The rotating cage is cylindrical and has several through holes on its surface. Both ends of the rotating cage are equipped with baffles and positioning rings. The positioning rings are located inside the rotating cage fixing groove. One of the positioning rings is equipped with an internal gear that meshes with a gear. One end of the inlet pipe is located inside the rotating cage.
[0005] Furthermore, the rotating cage is provided with several partitions, which are evenly distributed with the rotating cage as the center.
[0006] Furthermore, the partition is not located in the radial direction of the rotating cage.
[0007] Furthermore, the box body is provided with a receiving plate, and the receiving plate is provided with protective plates on both sides. One end of the receiving plate is located inside the rotating cage, and the other end is located outside the box body. The end of the receiving plate inside the rotating cage is higher than the other end.
[0008] Compared with existing technologies, the advantages of this invention are: it can continuously separate sand and gravel from sewage and pour out the separated sand and gravel. Attached Figure Description

Detailed Implementation
[0014] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] The sludge thickening equipment for ecological treatment of water conservancy and river channels includes a sand and gravel cleaner and a belt sludge thickener. The belt sludge thickener is existing technology and will not be described here. The sand and gravel cleaner includes a housing 1 and a rotating drum 2. The housing 1 is equipped with an inlet pipe 3, a motor support 4, an outlet pipe 5, and a rotating drum fixing groove 6. The inlet pipe 3 is used to receive sewage. The motor support 4 houses a motor 7, which has a gear 8. The outlet pipe 5 is equipped with a water pump 9, which is connected to the belt sludge thickener. The rotating drum fixing groove 6 includes an inner ring 10 and an outer ring 10. 1. The rotating cage 2 is cylindrical, with several through holes 12 on its surface. These through holes 12 can filter sand and gravel from the wastewater. Both ends of the rotating cage 2 are equipped with baffles 13 and positioning rings 14. The baffles 13 can block the filtered sand and gravel, and the positioning rings 14 are located within the rotating cage fixing groove 6, allowing the rotating cage 2 to rotate within it. One of the positioning rings 14 has an internal gear 15, which meshes with gear 8. When the motor 7 rotates, it drives the rotating cage 2 to rotate. One end of the water inlet pipe 3 is located inside the rotating cage 2. Simultaneously, due to the internal… Gear 15 occupies part of the space of positioning ring 14, so the height of the corresponding inner ring 10 can be lowered to make room for inner gear 15. Water inlet pipe 3 can directly introduce sewage into the rotating cage 2. The rotating cage 2 has several baffles 16 inside, evenly distributed around the rotating cage 2. The baffles 16 are not located radially on the rotating cage 2; they are inclined relative to the radial direction of the rotating cage 2. When there is sand or gravel inside the baffles 16, as the rotating cage 2 rotates, the sand or gravel will be carried to a higher position by the baffles 16. When the baffles 16 are parallel to the ground... After the surfaces are parallel, the sand and gravel will roll outward and fall. Compared to setting the partition 16 radially on the rotating cage 2, setting the partition 16 at a slight inclination can bring the sand and gravel to a higher place before falling. The box body 1 is provided with a receiving plate 17, and the receiving plate 17 is provided with a guard plate 18. When the sand and gravel fall, they fall into the receiving plate 17. One end of the receiving plate 17 is located inside the rotating cage 2, and the other end is located outside the box body 1. The height of the end of the receiving plate 17 inside the rotating cage 2 is higher than that of the other end. At this time, the sand and gravel will fall from the high place downward and be discharged from the rotating cage 2.
[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
