Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a grille device for rural sewage treatment. Background Art

[0002] In order to protect the rural ecological environment, residents' health and rural sustainable development, it is necessary to treat rural sewage. Since the source of rural sewage is mostly agricultural production, and the sewage generated by agricultural production cannot be collected and treated through pipes like in cities, in rural areas, sewage is mainly collected and guided through collection tanks so that sewage can flow to sewage treatment sites. Since collection tanks are mostly open, there are many debris in rural sewage. In order to prevent the debris in these sewage from entering the subsequent equipment and increasing the load of the subsequent equipment, it is necessary to intercept the debris in the sewage by setting a grille in the collection tank. The debris in rural sewage is mostly leaves. When using more flat grilles, although there is a certain interception effect on the leaves, since the flat grilles are perpendicular to the direction of water flow, the impact force of the water flow on the grille is large, and the leaves are easily broken under the impact of the water flow. The broken leaves are reduced in size and will pass through the gaps in the grille, resulting in poor interception effect on the leaves. Therefore, a grille for intercepting leaves is needed. Utility Model Content

Detailed Embodiments

[0016] Please refer to Figures 1 - 4, the present utility model provides the following technical solutions: It includes a cylindrical grille 1 and a driving motor 13, characterized in that: an impurity cleaning component 2 is provided inside the cylindrical grille 1. The impurity cleaning component 2 includes a plurality of trapezoidal guide plates 21. The sides of the plurality of trapezoidal guide plates 21 are connected to each other. The upper bases of the plurality of trapezoidal guide plates 21 are located on the same side, and the lower bases of the plurality of trapezoidal guide plates 21 are located on the other side. The plurality of trapezoidal guide plates 21 are fixedly connected to the inner wall of the cylindrical grille 1 through a plurality of triangular connecting plates 211, and the trapezoidal guide plates 21 are not parallel to the central axis of the cylindrical grille 1. The driving motor 13 is located on one side of the cylindrical grille 1. A leaf collection groove 3 is provided at the rear of the cylindrical grille 1, and the leaf collection groove 3 is slidably connected to the outer wall of the cylindrical grille 1.

[0017] In this implementation: It includes a cylindrical grille 1 and a driving motor 13. Both sides of the cylindrical grille 1 are in an open state. When the cylindrical grille 1 is located inside the collecting trough, the open sides of the cylindrical grille 1 are in contact with the inner walls on both sides of the collecting trough. The lower part of the cylindrical grille 1 is located inside the collecting trough, and the bottom of the cylindrical grille 1 is in contact with the bottom of the collecting trough. When sewage passes through the inside of the collecting trough, it will pass through the meshes of the cylindrical grille 1. By means of the cylindrical grille 1, the leaves in the sewage can be intercepted. Since the part of the cylindrical grille 1 in contact with the sewage is an arc surface, the impact force of the sewage flow on the cylindrical grille 1 can be reduced when the sewage flows, thereby reducing the probability of the leaves being broken by the water flow impact, which is beneficial to ensuring the interception effect of the leaves. An impurity cleaning component 2 is provided inside the cylindrical grille 1, and the impurity cleaning component 2 is fixedly connected to the cylindrical grille 1. When the cylindrical grille 1 rotates in the collecting trough, the impurity cleaning component 2 will rotate accordingly. The impurity cleaning component 2 includes a number of trapezoidal guide plates 21. The sides of the number of trapezoidal guide plates 21 are connected to each other. The sides of the number of trapezoidal guide plates 21 are fixedly connected. Therefore, there are no gaps between the number of trapezoidal guide plates 21. The upper bases of the number of trapezoidal guide plates 21 are on the same side, and the lower bases of the number of trapezoidal guide plates 21 are on the other side. The number of trapezoidal guide plates 21 is fixedly connected to the inner wall of the cylindrical grille 1 through a number of triangular connecting plates 211. Since the trapezoidal guide plate 21 is trapezoidal, there is a gap between the side of the trapezoidal guide plate 21 and the inner side of the cylindrical grille 1. Through the connection of the triangular connecting plate 211 with the trapezoidal guide plate 21 and the cylindrical grille 1, the gap between the trapezoidal guide plate 21 and the cylindrical grille 1 can be filled, so that a number of non-communicating spaces are formed between the number of trapezoidal guide plates 21 and the cylindrical grille 1. Since the shapes of most impurities are relatively irregular, the angle at which the impurities contact the cylindrical grille 1 will affect the interception effect of the cylindrical grille 1 on the impurities. Through the cylindrical grille 1, the impurities will experience two filtrations when passing through the cylindrical grille 1, which is beneficial to improving the interception effect of the impurities. At the same time, due to the number of non-communicating spaces between the impurity cleaning component 2 and the cylindrical grille 1 and the synchronous rotation of the impurity cleaning component 2 and the cylindrical grille 1, the intercepted impurities will move to the upper half of the cylindrical grille 1 as the impurity cleaning component 2 rotates. And the trapezoidal guide plate 21 is not parallel to the central axis of the cylindrical grille 1. When the cylindrical grille 1 is in a horizontal state, the central axis of the cylindrical grille 1 is also in a horizontal state. Since the trapezoidal guide plate 21 is not parallel to the central axis of the cylindrical grille 1, the trapezoidal guide plate 21 is in an inclined state. When the trapezoidal guide plate 21 rotates until both the upper base and the lower base are parallel to the ground, the height of the upper base of the trapezoidal guide plate 21 is higher, and the height of the lower base of the trapezoidal guide plate 21 is lower, making the trapezoidal guide plate 21 keep an inclined state with the ground.Thus, the impurities between the trapezoidal guide plate 21 and the cylindrical grille 1 can slide down to the outside of the cylindrical grille 1 and fall outside the water collecting tank along with the inclination angle of the trapezoidal guide plate 21. The drive motor 13 is located on one side of the cylindrical grille 1. By installing the drive motor 13 on one side of the water collecting tank, the rotation of the cylindrical grille 1 can be controlled by the drive motor 13. A leaf collecting groove 3 is provided at the rear side of the cylindrical grille 1, and the leaf collecting groove 3 is slidably connected to the outer wall of the cylindrical grille 1. Since the leaves in the sewage will be in full contact with the sewage, after the leaves are wetted, the water molecules on their surfaces will increase the adhesion between the leaves and the metal surface. The water acts as a bridge, filling the tiny gaps between the leaves and the metal surface, thus generating a certain adhesion. Moreover, the wetted leaves will have increased flexibility, enabling them to better conform to the shape of the metal surface and further enhancing the possibility of adhesion. Therefore, when the leaves are intercepted by the cylindrical grille 1, the leaves will be adsorbed on the outer side of the cylindrical grille 1 and move upward as the cylindrical grille 1 rotates. When the leaves move to the position of the leaf collecting groove 3, since there is no gap between the leaf collecting groove 3 and the outer side of the cylindrical grille 1, the leaves will be scraped off and collected from the surface of the cylindrical grille 1 by the leaf collecting groove 3. Through the shape and rotation of the cylindrical grille 1, the impact force of the water flow on the leaves can be reduced while intercepting the leaves, thereby reducing the probability of the leaves being broken by the water flow impact, which is beneficial to improving the interception effect of the leaves. And as the cylindrical grille 1 rotates, the leaves can be quickly taken out of the sewage, further improving the efficiency of cleaning the leaves in the sewage. At the same time, the cylindrical grille 1 can filter the sewage in two layers, and the assistance of the impurity cleaning component 2 is beneficial to improving the cleaning effect of other impurities and leaf fragments in the sewage.

[0018] A plurality of connecting frames 11 are provided on both sides of the cylindrical grille 1, and the positions of the plurality of connecting frames 11 correspond to those of the triangular connecting plate 211; one end of the connecting frame 11 is fixedly connected to the cylindrical grille 1, and at the same time, the plurality of connecting frames 11 are fixedly connected to the triangular connecting plate 211.

[0019] One end of the plurality of connecting frames 11 away from the cylindrical grille 1 is provided with a fixing plate 12, and a connecting shaft 121 is provided on the side of the fixing plate 12 away from the cylindrical grille 1; the drive motor 13 is connected to one of the connecting shafts 121; the fixing plate 12 is fixedly connected to the ends of the plurality of connecting frames 11, one end of the connecting shaft 121 is fixedly connected to the side of the fixing plate 12 away from the cylindrical grille 1, and the connecting shaft 121 and the central axis of the cylindrical grille 1 are located on the same straight line.

[0020] A support seat 14 is provided on the side of the cylindrical grille 1 away from the drive motor 13, and the support seat 14 is rotatably connected to one of the connecting shafts 121; by installing the support seat 14 on the outside of the water collecting tank, the support seat 14 can support the cylindrical grille 1.

[0021] A support plate 131 is provided at the rear side of both the driving motor 13 and the support base 14, and the leaf collecting trough 3 is fixedly connected to the two support plates 131; the support plates 131 are in a horizontal state, and the two support plates 131 can support the leaf collecting trough 3, so that the leaf collecting trough 3 is fixed at the rear side of the cylindrical grille 1.

[0022] The working principle and usage process of the present utility model: When in use, the cylindrical grille 1 can intercept the leaves in the sewage. Since the part of the cylindrical grille 1 in contact with the sewage is an arc surface, the impact force of the sewage flow on the cylindrical grille 1 can be reduced. Since the leaves in the sewage will be in full contact with the sewage, after the leaves are wetted, the water molecules on their surfaces will increase the adhesion between the leaves and the metal surface. Water plays a role of a bridge, filling the tiny gaps between the leaves and the metal surface, thus generating a certain adhesion. Moreover, the flexibility of the wetted leaves will increase, enabling them to better conform to the shape of the metal surface, further enhancing the possibility of adhesion. Therefore, when the leaves are intercepted by the cylindrical grille 1, the leaves will be adsorbed on the outer side of the cylindrical grille 1 and move upward as the cylindrical grille 1 rotates. When the leaves move to the position of the leaf collecting trough 3, since there is no gap between the leaf collecting trough 3 and the outer side of the cylindrical grille 1, the leaves will be scraped off and collected from the surface of the cylindrical grille 1 by the leaf collecting trough 3. At the same time, since the trapezoidal guide plate 21 is not parallel to the central axis of the cylindrical grille 1, the trapezoidal guide plate 21 is in an inclined state. When the upper base and the lower base of the trapezoidal guide plate 21 are both parallel to the ground during rotation, the height of the upper base of the trapezoidal guide plate 21 is higher, while the height of the lower base of the trapezoidal guide plate 21 is lower, so that the trapezoidal guide plate 21 remains in an inclined state with the ground, thereby enabling the impurities between the trapezoidal guide plate 21 and the cylindrical grille 1 to slide down to the outside of the cylindrical grille 1 along the inclination angle of the trapezoidal guide plate 21 and fall outside the water collecting trough.
