Description

Technical Field

[0001] The utility model relates to the technical field of water inlet filtration, in particular to an artificial wetland water inlet filtration structure. Background Art

[0002] Artificial wetlands are artificially constructed and controlled swamp-like ground, generally composed of plants, microorganisms and filler matrices, and are used to treat sewage and purify the air. However, after the artificial wetlands are built, some places "just build and don't care", causing the artificial wetlands to have a reduced sewage treatment capacity or no longer be able to be recycled after a period of operation, making the artificial wetlands lose their original value. Poor artificial wetland cycles not only fail to achieve the expected purpose of purifying the environment, but also cause secondary pollution to the environment and cause a huge waste of resources. Among them, regular renewal and replenishment of water sources for artificial wetlands plays a vital role in maintaining the good ecology of artificial wetlands. For example, the patent subject "A method for water inlet to artificial wetlands" Filter structure", application number "202320038634.0", through the setting of upper slots, lower slots, nets, filter cotton and gauze layers, the cleaning structure is installed inside the mobile slot, the two sides of the external block are respectively aligned with the two sets of side plates, the threaded hole A is aligned with the threaded hole C, and the two are fixed with bolts. The two sets of filter blocks are respectively inserted into the upper slots and the lower slots. When water is introduced through the water inlet pipe, the nets, filter cotton and gauze layers will filter impurities in the water to prevent water from polluting the artificial wetland. However, the device can only filter impurities in sewage, and cannot reflux and collect impurities, resulting in impurities remaining in the water inlet pipe for secondary fermentation, which pollutes the water inlet pipe and affects the filtering effect of the water inlet pipe on sewage.

[0014] As a preferred technical solution of the utility model, one end of the water inlet pipe close to the U-shaped pipe is fixedly connected with a joint, and the joint is communicated with the water inlet pipe.

When the filter screen of the utility model is moving, the impurities accumulated on the surface of the filter screen are affected by the rebound of the filter screen, so that the impurities can float backwards, and the impurities and sewage can enter the interior of the impurity suction tube through the opening. Since the lower surface of the impurity suction tube is open, the impurities can be washed through the impurity suction tube by water and fall into the interior of the U-shaped tube. The filter cloth can be used to intercept the impurities in the U-shaped tube, so that the impurities in the sewage can be collected to prevent the impurities from being retained in the water inlet pipe and causing secondary fermentation.

[0034] When the water inlet pipe 1 is discharging sewage, the sewage can pass through the interior of the filter screen 12, so that the filter screen 12 can filter the impurities in the sewage, and the filter screen 12 is affected by the impact of the sewage discharge, so that the filter screen 12 can move left and right inside the water inlet pipe 1. When the filter screen 12 is moving, the impurities accumulated on the surface of the filter screen 12 are affected by the rebound of the filter screen 12, so that the impurities can float backward, and the impurities and sewage can enter the interior of the impurity suction tube 6 through the opening 13. Since the lower surface of the impurity suction tube 6 is open, the impurities can be washed by water through the impurity suction tube 6 and fall into the interior of the U-shaped tube 8. The filter cloth 15 can be used to intercept the impurities in the U-shaped tube 8, so that it can collect the impurities in the sewage and prevent the impurities from being retained in the water inlet pipe 1 and causing secondary fermentation.

[0035] See also Figure 2 A spring 3 is fixedly connected to the side surface of the filter screen 12 , and a flow plate 4 is fixedly connected to one end of the spring 3 away from the filter screen 12 .

[0036] When the filter screen 12 is filtering impurities in the sewage, the flow plate 4 is subjected to the impact force of sewage discharge, so that the flow plate 4 can drive the spring 3 and the filter screen 12 to move left and right inside the water inlet pipe 1. The elasticity of the spring 3 can generate a pulling force between the filter screen 12 and the flow plate 4, and the flow plate 4 and the filter screen 12 can bounce inside the water inlet pipe 1, so that impurities are not easily accumulated on the surface of the filter screen 12.

[0037] See also Figure 2 The side surface of the flow plate 4 is fixedly connected with a transverse plate 9, and the upper surface and the lower surface of the transverse plate 9 are movably connected with a movable plate 10 through bearings.

[0038] When the flow plate 4 and the filter screen 12 move left and right, the movable plate 10 can move according to the moving directions of the flow plate 4 and the filter screen 12 by utilizing the movement of the movable plate 10 .

[0039] See also Figure 2 and Figure 4The side surface of the movable plate 10 is fixedly connected with a connecting plate 11 , the side surface of the connecting plate 11 is fixedly connected with a mounting plate 18 , and the side surface of the mounting plate 18 is provided with a soft board 17 .

[0040] When the movable plate 10 swings left and right, the connecting plate 11, the mounting plate 18 and the soft plate 17 of the movable plate 10 move. Since the soft plate 17 fits the surface of the filter screen 12, the soft plate 17 can beat the filter screen 12, thereby facilitating the soft plate 17 to clean impurities on the surface of the filter screen 12 and prevent the accumulation of impurities and the filtration from affecting the blockage of the water inlet pipe 1.

[0041] See also Figure 2 The inner wall of the water inlet pipe 1 is fixedly connected with a limiting block 5, and the side surface of the limiting block 5 is fixedly connected with a stop block 2.

[0042] Since two groups of resistance blocks 2 are arranged inside the water inlet pipe 1, one group of resistance blocks 2 is located on the left side of the filter screen 12, and the other group of filter screen 12 is located on the right side of the flow plate 4, when the filter screen 12 and the flow plate 4 move, the resistance blocks 2 can limit the moving position of the filter screen 12 and the flow plate 4, and by utilizing the elasticity of the spring 3, the filter screen 12 and the flow plate 4 can bounce left and right on the surface of the resistance blocks 2, so as to push the impurities to the right conveniently.

[0043] See also Figure 1 One end of the water inlet pipe 1 close to the U-shaped pipe 8 is fixedly connected with a joint 7, and the joint 7 is communicated with the water inlet pipe 1.

[0044] The joint 7 is used to facilitate the connection of the water inlet pipe 1 with an external pipe body, so that external sewage can be discharged through the water inlet pipe 1 .

[0045] See also Figure 1 and Figure 6 The front surface and the rear surface of the joint 7 are both slidably connected with a push rod 22 , an end of the push rod 22 close to the joint 7 is fixedly connected with an extrusion plate 20 , and a clamping block 19 is fixedly connected with the front surface of the extrusion plate 20 .

[0046] When the push rod 22 moves, the push rod 22 can drive the extrusion plate 20 and the block 19 to move, so that the extrusion plate 20 and the block 19 can be connected to the external pipeline. Through the continuous movement of the pressure plate and the block 19, the external pipeline can be connected to the water inlet pipe 1, which is convenient for the use of the water inlet pipe 1.

[0047] See also Figure 1 and Figure 6 One end of the push rod 22 away from the extrusion plate 20 is fixedly connected to a hanging ring 21, and soft strips 23 are provided on the upper surface and the lower surface of the hanging ring 21.

The soft strip 23 can be used to increase the diameter of the push rod 22, so that the push rod 22 can be fixed inside the joint 7.

[0049] When in use, the joint 7 is connected to the external pipeline, and the push rod 22 can drive the extrusion plate 20 and the block 19 to move, so that the extrusion plate 20 and the block 19 can be connected to the external pipeline. Through the continuous movement of the pressure plate and the block 19, the external pipeline and the water inlet pipe 1 can be squeezed. When the push rod 22 is continuously engaged with the inside of the joint 7, the push rod 22 can drive the soft strip 23 to move and extend into the inside of the joint 7. The soft strip 23 can be used to increase the diameter of the push rod 22, so that the push rod 22 can be fixed inside the joint 7. The water inlet pipe 1 is connected to the pipeline. When the water inlet pipe 1 is connected to the pipeline, the external sewage can be discharged into the external sewage collection point through the water inlet pipe 1. The filter screen 12 can filter the impurities in the sewage. The flow plate 4 is subjected to the impact of the sewage discharge, so that the flow plate 4 can drive the spring 3 and the filter screen 12 to move left and right inside the water inlet pipe 1. The elasticity of the spring 3 is used to generate a pulling force between the filter screen 12 and the flow plate 4. The flow plate 4 and the filter screen 12 can bounce inside the water inlet pipe 1, and the filter screen 12 and the flow plate 4 can be connected. When the flow plate 4 moves, the block 2 can limit the moving position of the filter screen 12 and the flow plate 4. By utilizing the elasticity of the spring 3, the filter screen 12 and the flow plate 4 can bounce left and right on the surface of the block 2. When the flow plate 4 and the filter screen 12 move left and right, the movable plate 10 can be driven to swing left and right. When the movable plate 10 swings left and right, the connecting plate 11, the mounting plate 18 and the soft plate 17 of the movable plate 10 move. Since the soft plate 17 fits the surface of the filter screen 12, the soft plate 17 can beat the filter screen 12, thereby The soft plate 17 is convenient for cleaning impurities on the surface of the filter screen 12. When the filter screen 12 is moving, the impurities accumulated on the surface of the filter screen 12 are affected by the rebound of the filter screen 12, so that the impurities can float backwards, and the impurities and sewage can enter the interior of the impurity suction tube 6 through the opening 13. Since the lower surface of the impurity suction tube 6 is open, the impurities can be washed through the impurity suction tube 6 by water and fall into the interior of the U-shaped tube 8. The filter cloth 15 can be used to intercept the impurities in the U-shaped tube 8, so that the impurities can be sorted.
