Description

Technical Field

[0001] This utility model relates to an auxiliary accessory for an aluminum plate rolling mill, specifically, to a special gas collection hood for an aluminum plate rolling mill. Background Technology

[0002] The aluminum plate production process generates a large amount of dust-laden flue gas, which needs to be collected and treated. For example, Chinese Patent CN208960622U discloses an aluminum plate casting and rolling mill lubricated by waste oil combustion, in which a gas collection hood is installed above the aluminum plate casting and rolling mill, and the gas collection hood is connected to dust removal equipment for treating combustion waste gas. Chinese Patent CN216460845U discloses an aluminum plate rolling mill exhaust pipe, which can prevent dust from adhering to the inner wall of the exhaust pipe during the flue gas transportation process, thereby improving exhaust efficiency. However, since the gas collection hood is located above the equipment, after the dust enters the gas collection hood with the airflow, the dust collides with the inner wall of the gas collection hood and may accumulate on the inner wall of the gas collection hood, moving downwards along the inner wall of the gas collection hood and falling back onto the aluminum plate rolling mill equipment or aluminum plate.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a special gas collection hood for aluminum plate rolling mills.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A special gas collection hood for aluminum plate rolling mill includes a hood body with an open bottom. The hood body includes a conical section on the upper side and a straight section on the lower side. The conical section is narrower at the top and wider at the bottom. A sealing plate is provided on the top surface of the conical section. An exhaust port is provided in the center of the sealing plate. The exhaust port is connected to an exhaust pipe. An installation ring plate is provided on the exhaust pipe. Several installation holes are evenly provided on the installation ring plate. A dust collection trough is installed on the inner side of the hood body. The bottom of the dust collection trough is flush with the bottom of the hood body.

[0007] The interior of the enclosure is equipped with several partitions, which divide the interior of the enclosure into several air ducts. Each air duct has an exhaust port at its top, and each exhaust port is connected to an exhaust pipe. Each exhaust pipe is equipped with a mounting ring plate.

[0008] The straight section is a rectangular tube formed by four rectangular side plates, and the conical section is a conical tube formed by four trapezoidal side plates.

[0009] The dust collection trough includes a rectangular frame that is adapted to the rectangular cylinder. The inner side of the rectangular frame is provided with a tapered frame that is narrower at the top and wider at the bottom. The bottom surfaces of the tapered frame and the rectangular frame are aligned and connected to form a trough shape.

[0010] The height of the top surface of the tapered frame is greater than the height of the top surface of the rectangular frame.

[0011] Several ribs are evenly arranged on the upper side of the rectangular frame, and the ribs fit against the inner wall of the cover.

[0012] Several connecting plates are provided on the outer side of the rectangular frame. The connecting plates and the cover are provided with several connecting holes and can be detachably connected by bolts.

[0013] Compared to existing technologies, this utility model offers several advantages. It provides a specialized gas collection hood for aluminum plate rolling mills, featuring a scientific design and ease of use. Specifically, a dust collection trough is installed inside the hood. Dust-laden fumes, after colliding with the inner wall of the hood, fall downwards into the dust collection trough, preventing them from directly falling onto the aluminum plate rolling mill or the aluminum plate. Furthermore, multiple partitions inside the hood form several air guide tubes. Each air guide tube has a corresponding exhaust port at its top, and each exhaust port is connected to an exhaust pipe. An annular connecting plate is installed on the exhaust pipe. During installation, the mounting ring plate can be fixedly connected to the ceiling of the plant to secure the hood and ensure its stability. Simultaneously, the exhaust pipe can be connected to the exhaust port of an exhaust fan, and the exhaust port of the exhaust fan can be connected to a dust-laden gas treatment device for further processing.

[0018] like Figure 1 As shown, a special gas collection hood for aluminum plate rolling mill includes a hood body 1 with an open bottom surface. The hood body 1 includes a conical section 101 on the upper side and a straight section 102 on the lower side. The conical section 101 is narrower at the top and wider at the bottom. A sealing plate 103 is provided on the top surface of the conical section 101. An exhaust port is provided at the center of the sealing plate 103. The exhaust port is connected to an exhaust pipe 2. An installation ring plate 3 is provided on the exhaust pipe 2. Several installation holes are evenly provided on the installation ring plate 3. A dust collection trough 4 is installed on the inner side of the hood body 1. The bottom of the dust collection trough 4 is flush with the bottom of the hood body 1.

[0019] This special gas collection hood for aluminum plate rolling mills has the advantages of scientific design and ease of use. Specifically, a dust collection trough is set inside the hood. After colliding with the inner wall of the hood, the dust-laden gas falls downwards into the dust collection trough, preventing it from falling directly onto the aluminum plate rolling mill or the aluminum plate. At the same time, the exhaust pipe can be connected to the exhaust port of an exhaust fan, and the exhaust port of the exhaust fan can be connected to a dust-laden gas treatment device for processing.

[0020] In one embodiment, the interior of the hood 1 is provided with several partitions, which divide the interior of the hood 1 into several air guide tubes.

During installation, the mounting ring plate can be fixedly connected to the top surface of the factory building to secure the hood and ensure its stability. Specifically, the mounting ring plate can be bolted to the top surface of the factory building; preferably, the cross-section of the air guide tube is square, and the cross-sectional area of ​​the exhaust port is greater than 1 / 2 of the top surface of the air guide tube to avoid the exhaust port being too small and to ensure the ventilation effect.

[0021] In one embodiment, the straight section 102 is a rectangular cylinder formed by four rectangular side plates, and the conical section 101 is a conical cylinder formed by four trapezoidal side plates. Referring to the attached drawings, the straight section is relatively short, mainly to facilitate the installation of the dust collection trough, while the conical cylinder is relatively long, resulting in a larger opening at the lower end of the conical cylinder and increasing the air collection area.

[0022] In one embodiment, the dust collection trough 4 includes a rectangular frame 401 adapted to the rectangular cylinder. A tapered frame 402 with a narrow top and wide bottom is provided on the inner side of the rectangular frame 401. The bottom surfaces of the tapered frame 402 and the rectangular frame are aligned and connected to form a trough shape. The top surface of the trough shape is open, and the opening area is larger than the bottom surface area of ​​the trough shape.

[0023] In one embodiment, the height of the top surface of the tapered frame 402 is greater than the height of the top surface of the rectangular frame.

[0024] In one embodiment, a plurality of ribs 403 are evenly provided on the upper side of the rectangular frame. The ribs 403 are attached to the inner wall of the cover 1, which serves as a guide and enhances the stability of the structure.

[0025] In one embodiment, a plurality of connecting plates 5 are provided on the outer side of the rectangular frame. The connecting plates 5 and the cover 1 are respectively provided with a plurality of connecting holes and are detachably connected by bolts, so as to facilitate the disassembly of the dust collection trough for cleaning.

[0026] The above embodiments can be combined with each other.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
