Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and in particular to a drainage structure and a papermaking anaerobic tower. Background Technology

[0002] Paper mill wastewater contains a large amount of calcium ions. Tests showed that the calcium ion concentration at the anaerobic inlet was around 2000 mg / L. After entering the anaerobic tower, a portion is retained, with the remainder discharged through the drainage pipe to the next process. During drainage, scale easily forms on the drainage pipes, eventually clogging the entire pipes with calcium deposits, preventing water flow and halting the anaerobic tower's operation. Previously, the DN200 effluent PE pipes were individually dismantled, cleaned, and reinstalled, posing significant safety risks and increasing the workload for employees. To address this issue, our technicians improved the drainage pipes, replacing the vertical drainage pipes of the anaerobic tower with 250mm diameter flexible rubber hoses. The slight vibration of the hoses as the water flows down prevents calcium ions from condensing on the pipes. For the aerobic tank section, a ditch is used for water flow, with a 15cm drop at both ends. A platform is installed simultaneously with the ditch, allowing for easy cleaning of calcium deposits within the ditch without affecting operation. However, the drawback is that, because the anaerobic tower's drainage pipe is located outdoors, the flexible rubber hose is suspended in the air, with its lower end placed in a ditch. When the wind blows, the hose swings, which can cause the lower end to fly out of the ditch, or even the upper end to detach or the hose to break, resulting in damage to the hose and the inability to collect wastewater. Therefore, I have proposed a drainage structure and a papermaking anaerobic tower using this drainage structure. Utility Model Content

[0003] The technical problem to be solved by this utility model is to solve the problems existing in the background art and provide a drainage structure and a papermaking anaerobic tower. By elastically tensioning the flexible inner tube body and installing it in the outer tube body through an elastic element, it can ensure that the inner tube body can shake when draining, and in windy conditions, it can also limit the inner tube body in the outer tube body, making it less likely to cause the upper end of the inner tube body to fall off or break.

[0004] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: a drainage structure includes an outer pipe body, an inner pipe body, and elastic elements. The inner pipe body is a flexible water hose, and multiple elastic elements are provided on the outer wall of the inner pipe body. The elastic elements are connected to the outer pipe body to elastically tension and install the inner pipe body into the outer pipe body.

[0005] The outer tube is a steel wire mesh structure.

[0006] The outer tube has a perforated plate structure.

[0007] The elastic element is an elastic band.

[0008] The elastic element is a tension spring.

[0009] Connectors are fixed to one or both sides of the bottom of the outer tube.

[0010] The outer wall of the inner tube is provided with multiple pull rings, and the elastic element is connected to the pull rings.

[0011] The pull ring is mounted on the connecting ring, and the flexible connecting ring is connected to the outer wall of the inner tube.

[0012] The outer wall of the connecting ring is connected to a traction ring, and multiple pull rings are arranged in a circular array on the traction ring.

[0013] A papermaking anaerobic tower employs the aforementioned drainage structure.

[0014] The features of this utility model using the above-mentioned technical solution are: 1. This utility model installs a flexible inner tube inside the outer tube by elastically tensioning it with an elastic element. This ensures that the inner tube can vibrate during drainage and, in windy conditions, it can also confine the inner tube inside the outer tube, preventing the upper end of the inner tube from falling off or breaking.

[0015] 2. The outer tube of this utility model is a steel wire mesh structure with a hollow structure, which not only makes it lighter, but also allows the inner tube to sway when the wind passes through the outer tube in a windy environment, which can also help to remove condensation inside the inner tube. In addition, it is also convenient to install elastic components. Attached Figure Description

[0023] 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.

[0024] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0025] Example 1: See Figure 1-5 A drainage structure includes an outer pipe 10, an inner pipe 20, and elastic elements 30. The inner pipe 20 is a flexible water hose. Multiple elastic elements 30 are provided on the outer wall of the inner pipe 20. The elastic elements 30 are connected to the outer pipe 10 to elastically tension the inner pipe 20 inside the outer pipe 10.

[0026] This invention installs a flexible inner tube 20 inside the outer tube 10 by elastic tensioning through an elastic member 30. During drainage, the water flow impacts the inner wall of the inner tube 20, causing the inner tube 20 to vibrate. In windy conditions, the inner tube 20 is also confined within the outer tube 10, making it less likely for the upper end of the inner tube 20 to detach or break.

[0027] In this embodiment, the inner tube 20 is made of high-molecular PVC water hose.

[0028] In one of the solutions, see Figure 3 The outer tube 10 is a wire mesh structure with a hollow structure, which not only makes it lighter, but also allows the inner tube 20 to shake when the wind passes through the outer tube 10 in windy conditions. This helps to remove condensation inside the inner tube 20 and also makes it easier to install the elastic element 30.

[0029] In another embodiment, the outer tube 10 is a perforated plate structure. In this embodiment, the outer tube 10 is formed by rolling and welding the perforated plate, which also serves to allow for ventilation and facilitates the installation of the elastic element 30.

[0030] In one embodiment, the elastic element 30 is an elastic band, which includes elastic bands such as rubber bands and elastic bands. In use, one end of the elastic band can be bonded to the outer wall of the inner tube 20, and the other end can be bonded to or fastened to the outer tube 10.

[0031] In another option, see Figure 2 , 5 The elastic element 30 is a tension spring, with one end hooked on the inner tube 20 and the other end hooked on the outer tube 10.

[0032] See Figure 1 , 3 A connector 11 is welded to one or both sides of the bottom of the outer tube 10. The outer tube 10 is supported and installed on the top of the lower water tank through the connector 11. In this embodiment, the connector 11 is made of angle iron, and the angle irons on both sides are respectively supported on the top of the side walls on both sides of the lower water tank. The connector 11 is then connected and fixed to the water tank by bolts.

[0033] See Figure 5 The outer wall of the inner tube 20 is provided with multiple pull rings 22, and the elastic element 30 is connected to the pull rings 22. This facilitates the connection between the elastic element 30 and the inner tube 20. During connection, the elastic element 30 can be fastened or hooked onto the pull ring 22. The pull ring 22 can be made of nylon tape, and the pull ring 22 can be installed on the outer wall of the inner tube 20 by adhesive or sewing.

[0034] Furthermore, a pull ring 22 is disposed on a connecting ring 21, and the flexible connecting ring 21 is connected to the outer wall of the inner tube 20. The connecting ring 21 can be a nylon strip, and the connecting ring 21 is sleeved on the outer wall of the inner tube 20. The connecting ring 21 can be installed on the outer wall of the inner tube 20 by adhesive or sewing.

[0035] Furthermore, a traction ring 23 is connected to the outer wall of the connecting ring 21, and multiple pull rings 22 are arranged in a circular array on the traction ring 23. During production, the traction ring 23 is sewn onto the outer wall of the connecting ring 21, and the circumference of the traction ring 23 is longer than the circumference of the connecting ring 21. During sewing, the connecting ring 21 is left unseen.

[0036] Example 2: An embodiment provides a papermaking anaerobic tower, the drainage pipe of which adopts a drainage structure from embodiment 1.

[0037] The working principle or process of this utility model: See Figure 3 Multiple connecting rings 21 are spaced apart along the length direction on the outer wall of the inner tube 20, and multiple pull rings 22 are arranged on the connecting rings 21 along the circumferential direction.

[0038] During installation, the inner tube 20 is first connected to the inside of the outer tube 10 using the elastic element 30. Both ends of the inner tube 20 extend beyond the outer tube 10 by a certain height. The upper end of the inner tube 20 is then connected and fixed to the drain outlet at the bottom of the upper water tank using a clamp. Next, the top of the outer tube 10 is fitted over the drain outlet at the bottom of the upper water tank. A connector 11 is welded to the bottom of the outer tube 10. The connectors 11 on both sides are supported on the top of the side walls on both sides of the lower water tank. The connectors 11 are then connected and fixed to the water tank using self-drilling bolts. The lower end of the inner tube 20 is placed inside the lower water tank.
