Description

Technical Field

[0001] The present application relates to the field of bellows exhaust technology, and in particular to a cover plate structure of a bellows air hood. Background Art

[0002] In industrial production and various thermal systems, hood bellows, as key ventilation and heat exchange equipment, are widely used in heat exchange stations such as paper machine hoods, material evaporation, and material drying, as well as other applications requiring temperature control and air circulation. In traditional designs, hood bellows are often located on the upper part of the equipment, with the air inlet of the bellows often directly exposed to the environment. This can cause a large amount of condensation when drawing in hot air or steam from the outside due to the direct intersection of hot and cold air. This dripping condensation can affect product quality, cause discontinuity in production, and corrode the mechanical components within the bellows. It can also drip through the air inlet into the external environment or equipment, corroding the external equipment and affecting its operating efficiency and lifespan.

[0003] In the existing technology, the air inlets of the air hood bellows are set on both sides for air intake. The evaporated gas enters through the openings on both sides of the air hood bellows, and the condensed water accumulates on the bottom plate of the air hood. First, it is easy to cause corrosion to the bottom plate of the air hood. Secondly, when the condensed water accumulates to a certain level, the condensed water will also drip down from the openings on both sides of the air hood to the external equipment and paper sheets, which is easy to cause corrosion to the external equipment and paper sheets, and thus cause product quality problems of the paper sheets.

[0004] Based on this, there is an urgent need for a cover structure of a bellows hood to solve the above technical problems and realize the treatment of condensed water. Utility Model Content

A collecting component is provided on the side of the cover body, and the collecting component is arranged vertically to the first guide groove. The collecting component is used to drain the condensed water in the first guide groove.

[0009] Optionally, a second guide groove is further provided on the inclined baffle, and the second guide groove is used to collect condensed water on the back of the inclined baffle, and the second guide groove is connected to the collection component.

[0010] Optionally, the collecting assembly includes a third guide groove and a connecting piece, one end of the connecting piece is connected to the third guide groove, and the other end is used to connect to the cover plate body.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] The present application provides a bellows hood cover structure for collecting and treating condensed water, thereby reducing the corrosion of equipment or paper sheets caused by condensed water dripping. The specific implementation process of the present application is described as follows.

[0033] See also Figures 1 to 5 The present application provides a bellows hood cover structure comprising:

[0034] The cover plate body 01 is provided with a plurality of inclined baffles 02, and an air intake channel is provided between adjacent inclined baffles 02, and the air intake channel is connected with the air inlet 03 of the bellows, so that the gas enters the air inlet 03 from the air intake channel; a first guide groove 04 is provided at the bottom of the inclined baffle 02, and the first guide groove 04 is used to collect condensed water on the inclined baffle 02, and a collecting component is provided on the side of the cover plate body 01, and the collecting component is arranged perpendicular to the first guide groove 04, and the collecting component is used to drain the condensed water in the first guide groove 04.

[0035] The shape and size of the cover body 01 match the bottom of the bellows hood 09 to ensure a secure connection and tight seal. The cover body 01 is made of corrosion-resistant and high-temperature resistant materials to adapt to various industrial environments such as steel smelting and chemical production.

[0036] Several inclined baffles 02 are arranged on the cover body 01. These baffles 02 serve as air guides. Tilts 02 are set at a certain angle, effectively dispersing and guiding incoming air as it passes through the cover, reducing the likelihood of it directly impacting the bellows inlet 03. This reduces noise and airflow turbulence, improving intake efficiency. The baffles are equidistantly spaced, forming an air intake channel between adjacent baffles 02. This channel ensures precise alignment with the bellows inlet 03, creating a smooth air passage.

[0037] In the actual working process, such as in the papermaking environment, the gas in the environment is hot air. When the hot air enters the air inlet 03 of the bellows, condensation water is generated due to the alternation of hot and cold. The condensation water condenses on several inclined baffles 02. Since the inclined baffles 02 are inclined at a certain angle, the condensed condensation water will flow into the first guide groove 04 and be collected and discharged through the first guide groove 04.

[0038] The first guide groove 04 is located at the bottom edge of the inclined baffle 02 (the first guide groove 04 is located on the side facing the air inlet of the wind box). The shape and position of the first guide groove 04 ensure that it can effectively collect condensed water formed on the surface of the inclined baffle 02. The first guide groove 04 has a certain depth and width to accommodate a certain amount of condensed water and guide it to a designated location through gravity.

[0039] The collecting component is arranged on the side of the cover body 01 and is arranged perpendicular to the first guide groove 04. The collecting component is used to receive the condensed water flowing down from the first guide groove 04 and discharge it to the outside safely and efficiently, ensuring the reliability and long-term effectiveness of the condensed water management, thereby collecting and processing the condensed water at the fan air inlet 03.

[0040] In an optional embodiment, the inclined baffle 02 is further provided with a second guide groove 05, which is used to collect condensed water from the back of the inclined baffle 02. The second guide groove 05 is connected to a collection assembly. Specifically, the second guide groove 05 is located on the back of each inclined baffle 02 (i.e., the side facing away from the air inlet of the wind box), ensuring that condensed water can be effectively collected from both the front and back of the inclined baffle 02. The shape and depth of the second guide groove 05 are similar to those of the first guide groove 04. The second guide groove 05 is connected to the collection assembly, so that condensed water from both the front and back of the inclined baffle 02 can ultimately be collected in the collection assembly, thereby achieving comprehensive collection of condensed water and reducing the omission or accumulation of condensed water.

[0041] In an optional embodiment, the collection component includes a third guide groove 06 and a connector 07, one end of the connector 07 is connected to the third guide groove 06, and the other end is used to connect to the cover plate body 01, and the third guide groove 06 is used to collect the condensed water in the first guide groove 04. Specifically, the third guide groove 06 is long and narrow, and the width and depth of the third guide groove 06 must be sufficient to accommodate the condensed water flowing down from the first guide groove 04, and should also be sufficient to accommodate the condensed water flowing down from the second guide groove 05. In order to ensure corrosion resistance and durability, the third guide groove 06 is made of materials such as stainless steel, aluminum alloy or high-strength plastic. The connection between the third guide groove 06 and the cover plate body 01 is as follows Figure 3 As shown, the direction of the arrow represents the flow direction of the condensed water in the third guide groove 06.

[0042] One end of connector 07 is securely connected to third guide channel 06 via screws, clips, or other fasteners, while the other end is connected to cover plate body 01. In one embodiment, connector 07 is a retractable structure, allowing for fine-tuning of the position or angle of third guide channel 06 during installation to ensure smooth flow and discharge of condensate, enhancing the flexibility and adaptability of third guide channel 06.

[0043] In this optional embodiment, the bottom of the third guide trough 06 is sloped toward its ends. Slope refers to the angle of inclination of the trough bottom relative to the horizontal plane, with the slope gradually decreasing from one end to the other. The primary purpose of providing this slope in the third guide trough 06 is to utilize gravity to allow condensed water to flow naturally along the bottom, reducing water resistance and accelerating drainage.

[0044] In an optional embodiment, the cover body 01 is made of aluminum or stainless steel, or more specifically, aluminum alloy or high-strength heat-resistant plastic.

[0045] In an optional embodiment, the bottom of the first diversion trough 04 is tilted toward the collection assembly. This tilted design leverages gravity to allow condensed water to flow naturally and smoothly along the bottom of the trough toward the designated collection assembly. By reducing resistance to water flow in the diversion trough, drainage efficiency is improved, ensuring that the fluid is quickly and effectively collected and processed.

[0046] In an optional embodiment, collection assemblies are provided on both sides of the cover body 01, and the ends of the first guide groove 04 are inclined downward and connected to the collection assemblies. Specifically, the middle of the bottom of the first guide groove 04 is higher than the ends, so that condensed water can flow along the ends of the first guide groove 04 to the collection assemblies on both sides. This improves drainage efficiency and allows condensed water to flow quickly and smoothly to the collection assemblies, reducing the risk of stagnation and overflow.

[0047] In another optional embodiment, the first guide groove 04 is recessed inward from the surface of the inclined baffle 02, and the bottom of the first guide groove 04 extends toward the back of the inclined baffle 02. In this embodiment, the first guide groove 04 is a portion of the inclined baffle 02, that is, the two are integrally formed. The first guide groove 04 is recessed inward from the surface of the inclined baffle 02, and the bottom of the first guide groove 04 extends toward the back of the inclined baffle 02 (the second guide groove 05).

[0048] In an optional embodiment, the cover body 01 is connected to the bellows hood 09 by bolts. The bolt connection first ensures a stable connection between the cover body 01 and the bellows hood 09, and secondly, realizes a detachable function, which facilitates cleaning of the several inclined baffles 02 on the cover body 01.

[0049] In an optional embodiment, the inclined baffle 02 is connected to the cover body 01 via a rotation axis 08, allowing the inclined baffle 02 to rotate around the rotation axis 08. The rotation axis 08 is the core component connecting the inclined baffle 02 and the cover body 01, capable of withstanding the various forces and moments generated by the rotation of the inclined baffle 02. The rotation axis 08 is typically designed from a durable material, such as stainless steel or alloy steel, to ensure long-term stability and reliability.

[0050] It should be noted that the above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
