Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to an anti-blocking type drainage pipe structure. Background Art

[0002] Drainage pipes are usually used to discharge sewage, wastewater or rainwater, and are a vital part of building or urban infrastructure. The anti-blocking drainage pipe structure is a special drainage system designed to minimize or prevent blockage in the pipe system.

[0003] However, the existing anti-blocking drainage pipe structure usually adopts a filter screen installed in the middle of the drainage pipe to filter impurities to avoid clogging of the drainage pipe. However, the filtering capacity of the filter screen is limited. As time goes by, the filter screen will be blocked by impurities, resulting in a decrease in the flow of the drainage pipe or even complete blockage. Once the drainage pipe is blocked, it is difficult for the staff to know in time. Secondly, even if the staff learns of the situation after the pipe is blocked, they still need to close the drainage pipe and manually replace the filter screen. This process is not only time-consuming, but also requires a lot of manpower.

[0004] Therefore, we provide an anti-blocking drainage pipe structure. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-blocking drainage pipe structure to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, both ends of the anti-blocking box on one side close to the water inlet pipe are provided with box doors rotatably mounted through hinges, and the collecting screen cylinder is located on the inner side of the box door.

[0008] Preferably, a sealing groove is provided on one side of the connecting seat close to the adjustable screen seat, a sealing ring is fixedly installed inside the sealing groove, and the other side of the sealing ring is in contact with the adjustable screen seat.

[0009] Preferably, a slide groove is provided on one side of the connecting seat and on the upper and lower sides of the sealing groove, connecting blocks are welded at the upper and lower ends of the connecting seat, a guide rail is welded on one side of the connecting block, and a hydraulic rod is fixedly installed on the upper end of the guide rail.

[0010] Preferably, a placement groove is provided through the inside of the adjustable screen seat, and a clamping groove is provided on one side of the placement groove of one group of the adjustable screen seats, and a slide plate is welded on the side of the adjustable screen seat close to the connecting seat, and the slide plate is slidably installed inside the slide groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The anti-blocking drainage pipe structure is installed with electromagnetic valves and flow meters at the water inlet pipe and the water outlet pipe. When the flow meter value at the water inlet pipe differs greatly from the flow meter value at the water outlet pipe, it indicates that the screen is blocked. At this time, the controller can immediately control the electromagnetic valve of the water inlet pipe to close, and then slide and adjust the adjustable screen seat to automatically replace the new collecting screen. After the replacement is completed, the electromagnetic valve at the water inlet pipe is controlled to open. The entire replacement process will not cause the electromagnetic valve to be closed for a long time, and there is no need for real-time monitoring by the staff. Once blockage occurs, the collecting screen will be replaced automatically, providing sufficient time for the staff to clean the screen. At the same time, the drainage pipe will not be shut down for a long time, which greatly improves the automation and operation convenience of the equipment, effectively avoids the problem of long-term blockage of the drainage pipe and the screen, and ensures the continuous and stable operation of the production environment.

[0015] 2. Through the setting of the adjustable screen cylinder and the collecting screen cylinder, when the screen is blocked, the adjustable screen cylinder will automatically replace the collecting screen cylinder in the first time, avoiding the blockage of the drainage pipe and the screen. It not only improves the automation degree of the equipment, but also effectively reduces the operating burden of the maintenance personnel, ensuring the smooth operation of the equipment.

[0030] Working principle: First, a blocking-proof drainage pipe structure is moved to the working position. In the first step, the water inlet pipe 1 is connected to the drainage pipe through the connecting flange 11. In the second step, drainage begins. The water flows through the drainage pipe and flows into the water inlet pipe 1. Then, it passes through the collecting screen cylinder 9 inside the adjustable screen seat 8. After the impurities are screened out by the screen 92, the water flows out through the outlet pipe 4. In the third step, during the drainage process, the electromagnetic valve 5 and the flow meter 6 located on the outside of the water inlet pipe 1 and the outlet pipe 4 continuously detect the water flow. When the flow meter 6 at one end of the outlet pipe 4 and the flow meter 6 at one end of the water inlet pipe 1 have a large difference in value, it means that the screen 92 is blocked. In the fourth step, after the controller 3 receives this signal, it controls The electromagnetic valve 5 at the water inlet pipe 1 is closed, and the water flow stops at this time. The hydraulic rod 75 is controlled to extend again, and the hydraulic rod 75 drives the fixed plate 84 to slide to one side, and the fixed plate 84 drives the adjustable screen seat 8 to slide, thereby completing the replacement of the collecting screen cylinder 9. At this time, the clogged collecting screen cylinder 9 is in a non-working state. After the collection screen cylinder 9 is replaced, the electromagnetic valve 5 on the side of the water inlet pipe 1 is opened. In the fifth step, the staff opens the box door 21 of the anti-blocking box 2, takes the collecting screen cylinder 9 out of the placement slot 81, and cleans it. In the sixth step, the two groups of collecting screen cylinders 9 work in a cycle to ensure the normal discharge of water flow without being blocked by impurities. In this way, the use process of an anti-blocking drainage pipe structure is completed.

[0031] It should be noted that all the electrical devices mentioned above are electrically connected to the controller 3 .
