Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage filtration, in particular to a filtering device for municipal water supply and drainage. Background Art

[0002] Municipal water supply and drainage engineering is the lifeline of a city. Water supply and drainage is the design or management of a city's tap water and sewage discharge system. Water supply and drainage engineering is divided into water supply engineering and drainage engineering. Water supply engineering is the engineering that supplies living and production water for residents and factories, mines, and transportation enterprises, as well as water for fire fighting and road greening. Drainage engineering is the engineering that removes human domestic sewage, various wastewater from production, and excess surface water. In the water supply and drainage pipes, there are often a lot of dirt that can cause pipe blockage. If these dirt are not filtered and treated, it is very easy to cause the water supply and drainage pipes to be blocked. In the existing technology, it is often done by adding a filter in the middle of the water supply and drainage pipe. A filter device for filtering dirt, but generally the filter device filters and intercepts the dirt through a single filter mesh. Since the staff needs to clean the dirt on the surface of the filter mesh regularly, if they go down into the filter device to clean the dirt, it is not only troublesome but also increases the physical exertion of the staff. If the filter mesh is removed from the filter device and the filtered dirt is cleaned, during the process of cleaning the dirt, the filter device cannot continue to intercept the dirt because the filter mesh is removed, thereby causing the filter device to be unable to effectively and continuously filter the dirt, reducing its own practicality.

The two connecting plates 52 are connected to the front and rear ends of the filter plate 51, while the receiving plate 54 is connected to the bottom of the filter plate 51 and the bottom of the connecting plates 52, respectively. The two connecting plates 52, the filter plate 51, and the receiving plate 54 form a storage chamber. The handle 58 is mounted on the top of the filter plate 51. Two slide bars 53 are mounted on the outside of the two connecting plates 52 and are slidably mounted in the chute 4 of the filter box 1. Both the receiving plate 54 and the filter plate 51 are provided with multiple strip-shaped filter holes 55. The strip-shaped filter holes 55 on the receiving plate 54 are perpendicular to and connected to the strip-shaped filter holes 55 on the filter plate 51. A wedge-shaped surface 14 is provided on one end of the receiving plate 54, near the water inlet of the filter box 1. Multiple cleaning rods 56 pass through the strip-shaped filter holes 55 of the filter plate 51 and are vertically connected to fixing rods 57. The ends of the fixing rods 57 are fixedly mounted on the upper ends of the front and rear inner walls of the filter box 1. The fixing rods 57 are located on the side of the filter plate 51 near the water outlet of the filter box 1.

[0026] The filter frame is used to filter wastewater. The cleaner hole is used to clean the strip filter holes 55 of the filter frame. The connecting plate 52 is used to install and fix the filter plate 51. The filter plate 51 is mainly used to filter wastewater. The handle 58 makes it easy for staff to lift the filter frame from the filter box 1. The receiving plate 54 is used to guide and carry wastewater. The slide bar 53 allows the filter frame to slide up and down in a vertical direction. The cleaning rod 56 is used to clean the strip filter holes 55 of the filter plate 51. The fixing rod 57 is used to fix the cleaning rod 56.

[0027] like Figure 4 and 5 As shown, two square through holes 9 are provided in the middle of the cover plate 6, a mounting cavity 10 is provided between the two square through holes 9, and guide holes 11 are provided at the left and right ends of the mounting cavity 10, both of which are connected to the mounting cavity 10. A row of strip-shaped holes 8 is provided on each side of the mounting cavity 10, with each row of strip-shaped holes 8 having eight holes.

[0028] like Figure 6As shown, the limiting assembly 12 includes two connecting blocks 121, two protruding blocks 122, four plug rods 123, two telescopic rods 124, and two springs 125. The two ends of the two telescopic rods 124 are respectively connected to the two connecting blocks 121. The two springs 125 are respectively sleeved on the two telescopic rods 124, and the two ends of the two springs 125 are respectively abutted against the two connecting blocks 121. The sides of the two connecting blocks 121 away from the springs 125 are respectively connected to the two protruding blocks 122, and the two protruding blocks 122 are located in the middle of the two connecting blocks 121. Each connecting block 121 is connected to a plug rod 123 at both ends, and the two plug rods 123 are perpendicularly connected to the two ends of the connecting block 121. Two springs 125, two telescopic rods 124 and two connecting blocks 121 are installed in the installation cavity 10 of the cover plate 6, the two protruding blocks 122 are slidably installed in the square through holes 9 of the cover plate 6, and the four insertion rods 123 pass through the four guide holes 11. Under the push of the springs 125, the four insertion rods 123 can be inserted into the four limiting holes 13 of the filter box 1.

[0029] Connecting block 121 connects spring 125, telescopic rod 124, and raised block 122, driving four rods 123 to slide within guide hole 11. Raised block 122 facilitates operator control of the sliding of rods 123. Rods 123 lock and unlock the connection between cover plate 6 and filter box 1. Telescopic rod 124 connects the two connecting blocks 121 and mounts spring 125. Spring 125 provides the force necessary for rods 123 to insert into retaining holes 13 of filter box 1.

[0030] Working process description: When wastewater containing contaminants enters the filter box 1 through the water inlet pipe 2, the wedge-shaped surface 14 on the receiving plate 54 guides the contaminants onto the receiving plate 54. The contaminants are then drawn into the filter frame by the wastewater. The wastewater then flows out through the strip-shaped filter holes 55 of the filter plate 51, where the contaminants are trapped. Road water containing trash or leaves is intercepted by the cover plate 6 as it flows into the filter box 1. The road water then passes through the strip-shaped holes 8 of the cover plate 6 and into the filter box 1. After being filtered, the wastewater and road water flow out of the drain pipe 3. To clean the contaminants from the filter box 1, the operator uses the raised block 122 to press the two connecting blocks 121 together. This simultaneously compresses the spring 125, causing the four rods 123 to slide out of the retaining holes 13 of the filter box 1. The cover plate 6 is unlocked from the filter box 1, and the operator removes the cover plate 6 from the filter box 1. The staff lifts a filter frame by the handle 58, and the filter frame slides relative to the cleaner. The cleaning rod 56 of the cleaner slides from top to bottom relative to the strip filter holes 55 of the filter plate 51, that is, the cleaning rod 56 cleans the strip filter holes 55. The staff takes out the dirt in the lifted filter frame. The other filter frame continues to filter the dirt in the wastewater in the filter box 1 to prevent the dirt from flowing out. After the dirt in one filter frame is cleaned, the filter frame is pushed back into the filter box 1 to continue intercepting the dirt. The staff continues to lift the other filter frame. At the same time, the cleaning rod 56 of the cleaner cleans the strip filter holes 55 of the other filter frame, takes out the dirt in the other filter frame, and then pushes the filter frame back into the filter box 1. The staff presses the raised block 122 of the limit assembly 12, the two connecting blocks 121 approach each other, and the four plug rods 123 retract into the cover plate 6. When the cover plate 6 is placed into the mounting groove 7 of the filter box 1 , the two protruding blocks 122 are loosened, and under the action of the spring 125 , the four insertion rods 123 are inserted into the limiting holes 13 of the filter box 1 , thereby achieving locking between the cover plate 6 and the filter box 1 .

[0031] The above specific implementation methods are preferred embodiments of the present invention and cannot limit the present invention. Any other changes or other equivalent replacement methods that do not deviate from the technical solution of the present invention are included in the scope of protection of the present invention.
