Description

Technical Field

[0001] The utility model relates to the technical field of oxidized cloth air ducts, and particularly relates to a novel oxidized cloth air duct. Background Technique

[0002] In a wet desulfurization system, the reaction between the desulfurizer and sulfur dioxide generates sulfites, which will cause the COD of the desulfurized water quality to increase and cannot be directly discharged. Generally, an oxidation blower is used to blow air into the circulation pool to oxidize the sulfites. After long-term blowing in the pool, most of the sulfites can be oxidized into sulfates, and then the desulfurized wastewater can be collected and discharged. Oxidation air supply enterprises need to use oxidized cloth air ducts.

[0003] For example, the patent with the authorization announcement number CN211644742U in the disclosed technology can be applied, including a circulation pool, an oxidation air main pipe and a cloth air duct. The cloth air duct is composed of two first oxidation air branch pipes and multiple second oxidation air branch pipes. The multiple second oxidation air branch pipes are located between the two first oxidation air branch pipes. Although it can facilitate the full contact between the oxidation air and the circulating liquid, improve the oxidation efficiency, and is beneficial to the safe, economic and stable operation of the entire desulfurization system.

[0004] However, in the actual use process, there are still small drawbacks. For example, the cloth pipe for air passage lacks a support structure inside. After the air supply operation is completed, the cloth pipe is affected by external pressure, and the inner walls of the cloth pipe are mutually adhered. When the air is supplied again later, the cloth pipe is blocked from fully bulging, which will seriously affect the normal air supply operation of the cloth pipe. In addition, its air outlet pipe structure is relatively simple, and its air outlet direction is relatively single, which is not convenient for evenly supplying gas to the medium inside the pool, and its practical performance needs to be strengthened. Content of the Utility Model

[0005] The purpose of the utility model is to provide a novel oxidized cloth air duct to solve the problems raised in the above background technique, that is, the cloth pipe for air passage lacks a support structure inside. After the air supply operation is completed, the cloth pipe is affected by external pressure, and the inner walls of the cloth pipe are mutually adhered. When the air is supplied again later, the cloth pipe is blocked from fully bulging, which will seriously affect the normal air supply operation of the cloth pipe. In addition, its air outlet pipe structure is relatively simple, and its air outlet direction is relatively single, which is not convenient for evenly supplying gas to the medium inside the pool, and its practical performance needs to be strengthened.

[0006] To achieve the above object, the present utility model provides the following technical solutions: a novel oxidation type cloth air duct, including a cloth pipe, an air outlet pipe is provided at the bottom end of the outer wall of the cloth pipe, a cylinder is rotatably connected to the bottom end of the air outlet pipe, a plurality of air outlet holes are uniformly arranged in a ring shape on the outer wall of the cylinder from top to bottom in sequence, a vertical rod is vertically arranged at the center of the interior of the air outlet pipe, a plurality of blade plates are fixedly connected in a ring shape on the outer wall of the vertical rod from top to bottom in sequence, a curved rod is arranged in the cloth pipe, a plurality of rubber cylinders are uniformly sleeved on the outer wall of the curved rod at equal intervals, a first abutting block is fixedly connected to the outer wall of the rubber cylinder, the other end of the first abutting block is fixedly connected to a first rubber strip, the contact surface of the first rubber strip abuts tightly against the cloth pipe, convex rods are inserted at both ends of the upper surface of the first rubber strip, a second abutting block is sleeved on the outer wall of the convex rod, a second rubber strip is fixedly connected to the lower surface of the second abutting block, the contact surface of the second rubber strip abuts tightly against the cloth pipe, and a nut is threadedly connected to the outer wall of the convex rod, and the contact surface of the nut abuts tightly against the second abutting block.

[0007] Preferably, a plurality of balls are uniformly and slidably clamped on the lower surface of the cylinder.

[0008] Preferably, convex rings are provided at the centers of the lower sides of both sides of the outer wall of the cloth pipe, and the contact surfaces of the convex rings are fixedly connected to the second abutting blocks.

[0009] Compared with the prior art, the beneficial effects of the present utility model are: this novel oxidation type cloth air duct has the following advantages compared with the traditional technology:

[0010] Through the cooperation among the cloth pipe, the air outlet pipe, the cylinder, the air outlet holes, the vertical rod, the blade plates, the curved rod, the rubber cylinders, the first abutting block, the first rubber strip, the convex rod, the second abutting block, the second rubber strip and the nut, due to the abutting relationship between the curved rod and the inner wall of the rubber cylinder, the curved rod can be relatively stably located inside the cloth pipe. During the period when the cloth pipe is not supplying air, through the supporting effect, when the cloth pipe is subjected to external pressure later, the cloth pipe will not collapse and the inner walls will not be mutually adhered. During the subsequent air supply operation, it can ensure that the cloth pipe bulges smoothly and will not affect the normal air supply operation of the cloth pipe.

[0011] Through the cooperation among the cloth pipe, the air outlet pipe, the cylinder, the air outlet holes, the vertical rod, the blade plates, the curved rod, the rubber cylinders, the first abutting block, the first rubber strip, the convex rod, the second abutting block, the second rubber strip and the nut, after the air flows inside the cloth pipe during air supply, part of the air flow can be discharged through the air outlet pipe, the cylinder and the air outlet holes to contact the medium to be oxidized in the outside world.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3, the present utility model provides a new technical solution: a new type of oxidation cloth air duct, including a cloth pipe 1. At the bottom end of the outer wall of the cloth pipe 1, there is an air outlet pipe 2, and the air outlet pipe 2 is in communication with the inside of the cloth pipe 1. There can be multiple air outlet pipes 2, and the specific number is determined according to the area of the oxidation pond. The bottom end of the air outlet pipe 2 is rotatably connected to a cylinder 3, and the cylinder 3 is rotatably connected to the air outlet pipe 2 through a sealed bearing. A plurality of air outlet holes 4 are evenly arranged in a ring shape on the outer wall of the cylinder 3 from top to bottom. A vertical rod 5 is vertically arranged at the center of the inside of the air outlet pipe 2. A plurality of blade plates 6 are fixedly connected in a ring shape on the outer wall of the vertical rod 5 from top to bottom in sequence. A curved rod 7 is arranged inside the cloth pipe 1. A plurality of rubber cylinders 8 are evenly sleeved on the outer wall of the curved rod 7 at equal intervals. The rubber cylinders 8 are made of rubber material and have a certain flexibility. The inner wall of the rubber cylinder 8 is in tight contact with the outer wall of the curved rod 7. A first abutting block 9 is fixedly connected to the outer wall of the rubber cylinder 8. The other end of the first abutting block 9 is fixedly connected to a first rubber strip 10. Both the first rubber strip 10 and the second rubber strip 13 are made of rubber material and have a certain flexible performance. The first rubber strip 10 is in tight contact with the contact surface of the cloth pipe 1. Convex rods 11 are inserted into both ends of the upper surface of the first rubber strip 10. A second abutting block 12 is sleeved on the outer wall of the convex rod 11. A second rubber strip 13 is fixedly connected to the lower surface of the second abutting block 12. The second rubber strip 13 is in tight contact with the contact surface of the cloth pipe 1. A nut 14 is threadedly connected to the outer wall of the convex rod 11, and the nut 14 is in tight contact with the contact surface of the second abutting block 12. A plurality of ball bearings 15 are evenly and slidably clamped on the lower surface of the cylinder 3. The ball bearings 15 can roll but cannot be separated from the cylinder 3, which can reduce the friction between the lower surface of the cylinder 3 and the bottom surface inside the oxidation pond during the rotation of the cylinder 3. Convex rings 16 are arranged below the centers of both sides of the outer wall of the cloth pipe 1. The contact surface of the convex ring 16 is fixedly connected to the second abutting block 12. The convex ring 16 can be used for docking with external connectors to facilitate ensuring the stability of the cloth pipe 1 inside the oxidation pond.

[0019] Before the air outlet pipe 2 is installed at the bottom end of the outer wall of the pipe layout 1, the processing personnel first evenly distribute a plurality of rubber cylinders 8 inside the pipe layout 1, so that the convex rod 11 partially penetrates the pipe layout 1 and the first rubber strip 10 fits against the inside of the pipe layout 1. Then, the second rubber strip 13 and the second abutting block 12 are both sleeved on the upper part of the outer wall of the convex rod 10, and the nut 14 is threadedly connected to the convex rod 11 and abuts tightly against the second abutting block 12. At this time, the curved rod 7 sequentially penetrates through a plurality of rubber cylinders 8. Due to the abutting relationship between the curved rod 7 and the inner wall of the rubber cylinder 8, the curved rod 7 can be relatively stably located inside the pipe layout 1. During the period when the pipe layout 1 is not supplying air, the curved rod 7 plays a supporting role. When the pipe layout 1 is subsequently subjected to external pressure, the pipe layout 1 will not collapse and the inner walls will not fit and adhere to each other. During the subsequent air supply operation, it can be ensured that the pipe layout 1 bulges smoothly, without affecting the normal air supply operation of the pipe layout 1. Then, the processing personnel can install and dock the air outlet pipe 2 and the pipe layout 1. After the installation operation is completed, the air outlet pipe 2 can be laid evenly on the pipe layout 1 towards the lower part of the pool body. After the laying is completed, the air supply operation can be carried out inside the pipe layout 1. After the air is supplied inside the pipe layout 1, the air flow can flow inside it. Part of the air flow can be discharged through the air outlet pipe 2, the cylinder 3 and the air outlet 4 to contact the medium to be oxidized outside. During the period when the air flow circulates inside the pipe layout 1, it can generate a blowing and impact force on the vane 6, enabling the vertical rod 5 and the cylinder 3 to rotate evenly. During this period, a plurality of air outlets 4 can revolve around the vertical rod 5 as the center, so as to supply air evenly to the medium inside the surrounding pool body, enhancing the practical performance and facilitating the promotion and sales use.
