[0001] This utility model belongs to the field of overflow pipe technology, specifically relating to an absorbent overflow pipe. Background Technology

[0002] An overflow pipe is a pipe or device used to control liquid overflow. It is usually designed to guide excess liquid to another location when the liquid reaches a certain height or pressure to prevent liquid from overflowing or causing damage. The design and function of overflow pipes may vary in different application scenarios. Impurities in the water or external dust and debris can enter the overflow pipe, which can cause it to become blocked.

[0003] Patent application number 202420941772.4 discloses an anti-clogging overflow pipe, including an overflow pipe with a limit ring fixed to the top of the overflow pipe by bolts. A connecting rod is sleeved through the limit ring. A floating component is provided at the bottom of the connecting rod inside the overflow pipe, and a cover plate is provided at the top of the connecting rod at the top of the limit ring. A liquid outlet pipe is welded to one end of the overflow pipe. A first filter screen is fixed inside the liquid outlet pipe by a slot. An external threaded connecting pipe is welded to the bottom of the overflow pipe. A second filter screen can filter the liquid entering the overflow pipe from the external threaded connecting pipe to prevent impurities in the liquid from entering the overflow pipe. The first filter screen can filter the liquid in the liquid outlet pipe to prevent impurities from entering the overflow pipe through the liquid outlet pipe.

[0004] The aforementioned anti-clogging overflow pipe uses an embedded filter to prevent pipe blockage. However, the filter can adsorb impurities of various sizes, causing blockage. The embedded filter is difficult to clean, and the clogging fluid can affect the normal use of the overflow pipe, leading to blockage. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an absorption overflow pipe, which aims to solve the technical problem that the filter screen will adsorb impurities of various sizes and cause blockage, and the blockage of the filter screen will affect the normal use of the overflow pipe, leading to blockage of the overflow pipe.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides an absorption overflow pipe, including an overflow pipe body and a storage pipe fixed at the bottom of the overflow pipe body. A telescopic pipe is slidably inserted into the top of the overflow pipe body, and an absorption part for blocking large particulate impurities is fixed at the top of the telescopic pipe. A water outlet pipe is fixed at the bottom of the storage pipe, and a filter plate is fixedly inclined in the storage pipe. A sewage pipe is fixedly installed on the outer wall of the storage pipe, and a backflushing pipe is fixedly installed at the top of the water outlet pipe.

[0009] When using this technical solution, a telescopic tube is slidably inserted into the top of the overflow pipe. The absorption section at the top of the telescopic tube floats on the water surface via a float plate. The weight of the telescopic tube aligns the horizontal plane with the absorption tank. The absorption tank on the absorption section blocks large particles of impurities, while small particles of impurities floating on the water surface flow into the telescopic tube, facilitating the blocking of large particles of impurities and preventing large particles of impurities from clogging the filter structure. A storage pipe is fixedly installed at the bottom of the overflow pipe body. The filter plate fixed at an incline in the storage pipe filters fine impurities, which slide down into the storage chamber with the flushing water flow, greatly reducing the impurities adsorbed on the filter plate surface and reducing the frequency of filter plate cleaning. A drain pipe is installed on the storage pipe. After opening the control valves on the drain pipe and backwash pipe, and closing the control valve on the outlet pipe, the water flow enters along the backwash pipe to flush the filter plate, and the impurities are discharged from the drain pipe, improving the convenience of filter plate cleaning.

[0010] Preferably, both ends of the overflow pipe body are fitted with fastening rings, and both ends of the fastening rings are embedded with bolts.

[0011] Furthermore, a groove is provided at the top of the inner wall of the overflow pipe body, and a protrusion embedded in the groove is fixed at the bottom of the outer wall of the telescopic pipe.

[0012] Furthermore, the bottom end of the absorption section is fixedly equipped with floating plates in a ring array, and the top end of the absorption section is provided with multiple absorption grooves in a ring array.

[0013] Furthermore, a connecting part is fixedly installed at the top of the sewage pipe, and the bottom end of the overflow pipe body is threaded into the connecting part.

[0014] Furthermore, a storage cavity is provided on the top of the filter plate, and the drain pipe is connected to the storage cavity.

[0015] Furthermore, control valves are installed on the water outlet pipe, backflush pipe, and sewage pipe, and the opening at the top of the backflush pipe is located below the main body of the overflow pipe.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model has a telescopic tube slidably inserted into the top of the overflow pipe. The absorption part at the top of the telescopic tube floats on the water surface through a float plate. The weight of the telescopic tube makes the horizontal plane correspond to the absorption tank. The absorption tank on the absorption part blocks large particles of impurities, and small particles of impurities floating on the water surface flow into the telescopic tube, which facilitates the blocking of large particles of impurities on the water surface and avoids the situation where large particles of impurities cause blockage of the filter structure.

[0019] By fixing a storage pipe at the bottom of the overflow pipe body, a filter plate fixed at an inclination in the storage pipe filters out fine impurities. As the water flows, the impurities slide down into the storage chamber, greatly reducing the impurities adsorbed on the surface of the filter plate and reducing the frequency of cleaning the filter plate.

[0020] By installing a drain pipe on the storage pipe, opening the control valves on the drain pipe and backwash pipe, and closing the control valve on the outlet pipe, water flows along the backwash pipe to rinse the filter plate and then discharges the impurities from the drain pipe, thus improving the convenience of cleaning the filter plate.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This specific embodiment is an absorption overflow pipe, the structural schematic diagram of which is shown below. Figure 1 and Figure 2 As shown, the absorption overflow pipe includes an overflow pipe body 1 and a storage pipe 6 fixed at the bottom of the overflow pipe body 1. A telescopic pipe 11 is slidably inserted into the top of the overflow pipe body 1. An absorption part 4 for blocking large particulate impurities is fixed at the top of the telescopic pipe 11. A water outlet pipe 7 is fixed at the bottom of the storage pipe 6, and a filter plate 13 is fixedly inclined in the storage pipe 6. A sewage pipe 9 is fixedly installed on the outer wall of the storage pipe 6, and a backwash pipe 5 is fixedly installed at the top of the water outlet pipe 7.

[0029] Both ends of the overflow pipe body 1 are fitted with fastening rings 2, and both ends of the fastening rings 2 are embedded with bolts. The bolts are threaded into the water storage equipment to keep the fastening rings 2 and the overflow pipe body 1 fixed. The top of the inner wall of the overflow pipe body 1 is provided with a sliding groove 10. The bottom of the outer wall of the telescopic pipe 11 is fixed with a protrusion 16 embedded in the sliding groove 10. The protrusion 16 on the telescopic pipe 11 slides in the sliding groove 10, causing the absorption part 4 to move synchronously with the rise and fall of the water level. When the water level is lower than the overflow water level, the bottom of the groove... The wall supports the protrusion 16, preventing the telescopic pipe 11 and the absorption section 4 from continuously moving downwards to discharge water. The bottom end of the absorption section 4 is fixedly equipped with a float plate 12 in a ring array, and the top end of the absorption section 4 is provided with multiple absorption grooves 3 in a ring array. The absorption section 4 at the top of the telescopic pipe 11 floats on the water surface through the float plate 12. The weight of the telescopic pipe 11 makes the horizontal plane correspond to the absorption groove 3. The absorption grooves 3 on the absorption section 4 block large particles of impurities, and small particles of impurities floating on the water surface flow into the telescopic pipe 11.

[0030] like Figure 3 and Figure 4As shown, a connecting part 14 is fixedly installed at the top of the drain pipe 9, and the bottom end of the overflow pipe body 1 is threaded into the connecting part 14. A storage chamber 15 is provided at the top of the filter plate 13, and the drain pipe 9 is connected to the storage chamber 15. Control valves 8 are installed on the water outlet pipe 7, the backwash pipe 5, and the drain pipe 9. The opening at the top of the backwash pipe 5 is located below the overflow pipe body 1. The filter plate 13, which is fixed at an inclination in the storage pipe 6, filters out fine impurities, and the impurities slide down into the storage chamber 15 with the flushing of the water flow, which greatly reduces the impurities adsorbed on the surface of the filter plate 13 and reduces the cleaning frequency of the filter plate 13. By installing the drain pipe 9 on the storage pipe 6, after opening the control valves 8 on the drain pipe 9 and the backwash pipe 5, and closing the control valve 8 on the water outlet pipe 7, the water flow enters along the backwash pipe 5 to flush the filter plate 13 and then discharges the impurities from the drain pipe 9.

[0031] Working principle: When using the device of this technical solution, when the water level is too high, the absorption part 4 at the top of the telescopic pipe 11 floats on the water surface through the float plate 12. The weight of the telescopic pipe 11 makes the horizontal plane correspond to the absorption tank 3. The absorption tank 3 on the absorption part 4 blocks large particles of impurities, and small particles of impurities floating on the water surface flow into the telescopic pipe 11. The absorption tank 3 blocks large particles of impurities on the water surface, avoiding the situation where large particles of impurities cause blockage of the filter structure. The filter plate 13, which is fixed at an inclination in the storage pipe 6, filters fine impurities, and the impurities slide down into the storage chamber 15 with the flushing of the water flow, which greatly reduces the impurities adsorbed on the surface of the filter plate 13. When cleaning the filter screen, after opening the control valve 8 on the drain pipe 9 and the backwash pipe 5, the control valve 8 on the outlet pipe 7 is closed. The water flow enters along the backwash pipe 5 to flush the filter plate 13 and then discharges the impurities from the drain pipe 9, which improves the convenience of cleaning the filter plate 13.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
