[0002] Anti-clogging connecting pipes for sewage treatment are pipe connection parts specially designed for use in sewage treatment systems. They have the characteristics of preventing clogging. Such pipe connection parts can ensure the smooth flow of sewage during transmission and avoid the occurrence of clogging problems, thereby improving the efficiency and reliability of the sewage treatment system. They usually adopt special materials and designs to meet the special requirements in the sewage treatment environment. By using anti-clogging connecting pipes, the service life of the sewage treatment system can be extended and the frequency of maintenance and repair can be reduced;

[0003] A Chinese patent with publication number CN213253271U discloses an anti-clogging connecting pipe for municipal sewage treatment, including a pipe body, a sewage inlet pipe connected to the pipe body, a sewage inlet cover detachably provided on the sewage inlet pipe, a filtering device for blocking sediments is provided at the connection between the sewage inlet pipe and the sewage inlet cover, and a filtering device is provided in the sewage inlet pipe. The sewage flowing into the sewage inlet cover can be filtered through the filtering device, and the sediment in the sewage is filtered into the filtering device, and then the water is discharged to prevent the pipe body from being blocked due to a large amount of sediment. When cleaning, the staff only needs to clean the filtering device, and there is no need to enter the pipe body from the sewage inlet pipe to clean the pipe body, which saves manpower.

[0004] During the filtering process of the anti-clogging connecting pipe of the above-mentioned patent, foreign matter will be retained inside the filter holes after a long period of filtration and cause blockage, and it is difficult to dredge the blocked filter holes. On the other hand, the connecting pipe cannot actively remove the blocked objects during use. After filtering the liquid with large foreign matter, frequent cleaning and unblocking are required. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-clogging connecting pipe for sewage treatment. The suspension force of the sewage can push the blocking block, and the blocking block moves longitudinally upward after being pushed, and the longitudinal upward movement further pulls the dredging rod. After being pulled, the dredging rod can pass through the clogged filter hole to actively dredge the hole, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a kind of anti-clogging connecting pipe for sewage treatment, comprising an inlet pipe, a sewage inlet cover is arranged at the upper end inside the sewage inlet pipe, a shielding block is arranged at the upper end inside the sewage inlet pipe, a hollow structure is arranged inside the shielding block, a hollow structure is arranged inside the shielding block, inclined guide plates are arranged on both sides of the lower end of the shielding block, a transmission plate is arranged at the lower end inside the sewage inlet pipe, and a dredging rod is arranged in an array on one side of the transmission plate facing the guide plate.

[0007] Preferably, upper sliding rails for guiding are provided at both the front and rear ends of the shielding block, and the interior of the upper sliding rails is connected to the external sliding slot of the shielding block.

[0008] Preferably, the shielding block is made of plastic, and the exterior of the shielding block is coated with anti-rust paint.

[0009] Preferably, the two guide plates are inclined toward the middle of the sewage inlet pipe and welded and fixed in the middle position of the sewage inlet pipe. Five connecting blocks are evenly distributed laterally between the two guide plates, and the connecting blocks and the guide plates are an integral structure. The guide plates pass through the connecting blocks and are fixedly connected to the shielding blocks by metal cables.

[0010] Preferably, lower sliding rails are provided at both the front and rear ends of the transmission plate, and the interior of the lower sliding rails is connected to the sliding slots at the front and rear ends of the transmission plate.

[0011] Preferably, installation cavities are provided on both sides of the guide plate facing the interior of the sewage inlet pipe, a storage frame for filtering is provided inside the installation cavity, and filter holes are arranged in an array inside the storage frame and the guide plate, and the diameter of the filter holes is larger than the diameter of the dredging rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model filters sewage through the guide plate and the filter holes inside the storage frame. In the process of the filter holes being blocked by foreign matter in the sewage, the sewage will continue to block the inside of the sewage inlet pipe. When the filling causes the water level to continue to move up, the upward movement of the water level will cause the blocking block to move up due to the suspension force. During the upward movement, the transmission plate will be pulled by the metal cable, so that the transmission plate will drive the dredging rod to be inserted into the filter holes for active dredging. During the dredging process, due to the insertion of the dredging rod which is smaller than the diameter of the filter hole, the blocked foreign matter can flow to the inside of the storage frame along with the inclination of the liquid and the guide plate, and with the insertion of the dredging rod, the liquid can pass through the filter holes and be discharged. After the liquid is discharged, the horizontal plane moves downward, and the suspension force will reset the blocking block and the transmission plate. The dredging can be carried out in response to the blockage through the suspension force of the liquid and the insertion of the dredging rod, thereby reducing the frequency of manual dredging.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that during the filtration process of the existing anti-clogging connecting pipe, after a long period of filtration, foreign matter will be retained inside the filter hole and cause blockage, and the dredging process after the filter hole is blocked is more difficult, and on the other hand, the connecting pipe cannot actively remove the blocked objects during use, and after filtering the liquid with large foreign matter, frequent cleaning and dredging are required, this embodiment provides the following technical solutions:

[0022] A clogging-proof connecting pipe for sewage treatment comprises a sewage inlet pipe 1, wherein a sewage inlet cover 2 is arranged at the upper end of the sewage inlet pipe 1, and the sewage inlet cover 2 is directly placed at the upper end of the sewage inlet pipe 1 by its own weight. The sewage inlet cover 2 can be used to preliminarily filter the liquid flowing into the sewage inlet pipe 1, and large particles and foreign matter are retained outside. At the same time, the sewage inlet cover 2 can be used to prevent outsiders from stepping on the inside of the sewage inlet pipe 1. Figure 1As shown, when cleaning the filtered and retained liquid in the sewage pipe 1, the sewage inlet cover 2 can be directly removed to expose the upper end of the sewage inlet pipe 1;

[0023] In this embodiment, a shielding block 5 is provided at the upper end of the sewage inlet pipe 1, and a hollow structure is provided inside the shielding block 5, such as Figure 2 and Figure 4 As shown, both ends of the shielding block 5 are provided with upper sliding rails 3 for guiding, and the interior of the upper sliding rails 3 is connected to the external sliding slot of the shielding block 5. Through the connection of the upper sliding rails 3 to the slot of the shielding block 5, the shielding block 5 can be adjusted in horizontal height after being suspended by the liquid;

[0024] In this embodiment, the shielding block 5 is made of plastic, and the outside of the shielding block 5 is coated with anti-rust paint, which reduces the weight of the shielding block 5 and prevents the shielding block 5 from contacting corrosive substances and rusting, thereby preventing damage caused by rust. A hollow structure 6 is provided inside the shielding block 5;

[0025] In this embodiment, inclined guide plates 7 are provided on both sides of the lower end of the shielding block 5. The two guide plates 7 are inclined toward the middle of the sewage inlet pipe 1 and are welded and fixed at the middle position of the sewage inlet pipe 1. Figure 4 and Figure 5 As shown, five connecting blocks 10 are evenly distributed laterally between the two guide plates 7, and the connecting blocks 10 and the guide plates 7 are an integral structure. The guide plates 7 penetrate the connecting blocks 10 and are fixedly connected to the shielding blocks 5 through metal cables 11. The water level of the liquid rises due to the blockage of the sewage inlet pipe 1, and the rising water level can push the shielding blocks 5 to move upward. The upward movement of the shielding blocks 5 can pull the metal cables 11. A transmission plate 14 is provided at the lower end of the sewage inlet pipe 1. The metal cables 11 are pulled to drive the transmission plate 14 to move longitudinally upward, so that the transmission plate 14 moves toward the guide plate 7.

[0026] In this embodiment, a dredging rod 15 is arranged on one side of the transmission plate 14 facing the guide plate 7, and the dredging rod 15 is welded and fixed to the transmission plate 14. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the front and rear ends of the transmission plate 14 are both provided with lower sliding rails 4, and the interior of the lower sliding rails 4 is connected to the sliding slots at the front and rear ends of the transmission plate 14. The transmission plate 14 can be adjusted in the horizontal and longitudinal position after being pulled by the restriction of the lower sliding rails 4, thereby improving the stability of the transmission plate 14 and the shielding block 5 during the longitudinal movement.

[0027] In this embodiment, both sides of the guide plate 7 are provided with mounting cavities 8 facing the interior of the sewage inlet pipe 1. Figure 2 and Figure 3As shown, a receiving frame 9 for filtering is provided inside the installation cavity 8, and the external sewage is guided by the inclined guide plate 7 after passing through the shielding block 5, so that the liquid is actively filtered in the receiving frame 9, and the filtered objects can also be retained in the receiving frame 9, and the retention is also convenient for subsequent removal;

[0028] In this embodiment, the interior of the storage frame 9 and the guide plate 7 are both provided with filter holes 16 in an array, and the diameter of the filter holes 16 is larger than the diameter of the dredging rod 15, so that after the filter holes 16 are blocked, the dredging rod 15 is inserted vertically upward into the filter holes 16 to dredge the filter holes 16, and at the same time as the filter holes 16 are transported, Figure 2 , Figure 3 and Figure 4 As shown, sewage can flow out from the gap between the filter hole 16 and the dredging rod 15, and the blockage is dredged by the suspension force, thereby reducing the efficiency of manual dredging;

[0029] In this embodiment, an upper hanging ring 13 is welded to the upper end of the storage frame 9, and the upper hanging ring 13 is welded and fixed to the storage frame 9. Metal hooks 12 are provided at both the front and rear ends of the upper end of the upper hanging ring 13, and the metal hooks 12 are welded and fixed to the upper hanging ring 13. Figure 2 and Figure 3 As shown, the upper hanging ring 13 can be slid out from both sides of the shielding block 5. After the user takes out the dirt inlet cover 2, the storage frame 9 can be taken out from both sides of the shielding block 5. After taking out the storage frame 9, the foreign matter filtered in the storage frame 9 can be cleaned.

[0030] Working principle: when the device is used and sewage is filtered, the sewage passes through the sewage inlet cover 2 and is initially filtered. After the initial filtration, the sewage is guided by the inclined guide plate 7. After the liquid is guided, the sewage is filtered by the filter holes 16 in the storage frame 9. After the filter holes 16 inside the storage frame 9 are blocked, the water level continues to rise. During the continuous rise, the sewage will contact the guide plate 7 and be filtered by the filter holes 16 inside the guide plate 7. After the filter holes 16 inside the guide plate 7 are blocked, the water level rises again. The rising liquid generates buoyancy, which pushes the shielding block 5. After being pushed, the shielding block 5 moves longitudinally upward along the upper sliding rail 3. The longitudinal upward movement of the shielding block 5 can be achieved by the metal cable 11 pulling the transmission plate 14 through the connecting block 10, pulling the transmission plate 14 and then driving the dredging rod 15 on the surface of the transmission plate 14 to move toward the guide plate 7. The dredging rod 15 penetrates into the filter hole 16 to achieve dredging and alleviate the rise in water level.
