Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum smelting equipment, and specifically provides a flexible sealing fume hood. Background Technology

[0002] During electrode replacement in the aluminum electrolysis workshop, the replaced electrodes are placed on trays to cool. The temperature of these electrodes reaches nearly 700°C. The hot flue gas released during cooling contains large amounts of NaF, ALF3, HF, and SO2, severely polluting the working environment and threatening the health of employees. Therefore, it is necessary to use fume hoods to cover the electrodes and recover the flue gas released during cooling.

[0003] Currently, the specifications of residual electrode cooling fume hoods on the market are relatively fixed, mainly in two forms:

[0004] One type is an integrated continuous-fire fume hood, controlled by a single main drive unit, which raises and lowers synchronously. In this solution, the drive unit occupies little space and is easy to control, but it requires a certain level of precision in the placement of the residual electrode cooling plate, and it is difficult to flexibly add or remove equipment after it is installed.

[0005] Another option is multiple independent fume hoods, each controlled by a separate drive unit. This offers greater flexibility, but the multiple drive units require more space, and the separate control logic and energy consumption are also higher.

[0006] In summary, there is a lack of a more flexible device to adapt to the needs of different working conditions. Utility Model Content

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a flexible sealing smoke hood, including a hood body, a pull plate, a long brush and a pipe. The pull plate is assembled on the rear side of the hood body. The pipe runs through the wall panel of the hood body from the outside to the inside and is inserted into the interior of the hood body. The front and upper sides of the hood body are provided with continuous notches. The long brush is evenly arranged at the notches and the long brush completely covers the notches.

[0008] The enclosure is divided into a main enclosure and a secondary enclosure. The side wall of the main enclosure is provided with a lower bracket and an upper bracket. The secondary enclosure is spliced ​​to the main enclosure through the lower bracket and the upper bracket.

[0009] Furthermore, the lower bracket is an L-shaped plate with a U-shaped longitudinal section, and is fixedly installed from bottom to top at the corner of the bottom of the front side wall of the main cover.

[0010] Furthermore, the upper bracket is formed by bending a rectangular plate, and its longitudinal section is shaped like a "Z".

[0011] Furthermore, the upper bracket includes an upper horizontal plate, a vertical plate, and a lower horizontal plate. The upper and lower horizontal plates are integrally formed on the upper and lower ends of the vertical plate, respectively. The upper bracket is located at the corner of the upper end of the side wall of the main cover. The upper horizontal plate is attached to the outer surface of the upper wall panel of the main cover, the vertical plate is attached to the outer surface of the side wall panel of the main cover, and the lower horizontal plate is attached to the inner surface of the upper wall panel of the secondary cover.

[0012] Furthermore, a pull plate connector is assembled between two adjacent pull plates.

[0013] Furthermore, the pull plate is provided with weight reduction holes;

[0014] The pull plate connector includes spokes, clamping buckles, washers, and nuts. The clamping buckles are L-shaped and consist of a main clamping buckle and a secondary clamping buckle that engage. After engaging, the main clamping buckle and the secondary clamping buckle form a clamping groove that matches the shape of the pull plate. Both the main clamping buckle and the secondary clamping buckle have slots on their sidewalls near the clamping groove. The sidewalls of the main clamping buckle and the secondary clamping buckle, together with the sidewall of the pull plate, form a strip groove. The two spokes are respectively embedded in the strip groove and the slot. Multiple washers are fitted onto the spokes, and multiple nuts are screwed onto the spokes. The nuts, in conjunction with the washers, press against the main clamping buckle and the secondary clamping buckle.

[0015] Furthermore, the cover is assembled from wall panels and a steel frame, and the wall panels consist of a panel and an insulation layer;

[0016] The inner and outer sides of the steel frame are fitted with panels, and the cavity formed by the steel frame and the panels on the inner and outer sides is filled with thermal insulation material to form a thermal insulation interlayer.

[0017] Furthermore, the side of the lower horizontal plate is integrally formed with a guide wing, which is curved upward and has an angle of 160 degrees to 175 degrees with the lower horizontal plate. A deformation groove is provided at the connection between the guide wing and the lower horizontal plate.

[0018] Furthermore, short brushes are provided at the seam between the main cover and the secondary cover.

[0019] The beneficial effects of using this utility model are:

[0020] By freely combining multiple main hoods and multiple auxiliary hoods, different schemes such as one-to-one and one-to-two can be realized according to different torque conditions of the power mechanism, which greatly improves the flexibility of the arrangement of the smoke hood and residual electrode tray, while reducing the space occupied by the power mechanism.

[0021] The use of pull plate connectors strengthens the connection between the pull plates, distributes the load at the connection between the main cover and the secondary cover during the lifting process, and offers a flexible assembly method, facilitating the free combination of multiple main covers and multiple secondary covers.

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] Reference Figures 1-7 A flexible sealing smoke hood includes a hood body, a pull plate 3, a long brush 4 and a pipe 8. The pull plate 3 is assembled on the rear side of the hood body. The pipe 8 passes through the wall panel of the hood body from the outside to the inside and is inserted into the interior of the hood body. The front and upper sides of the hood body have continuous notches. The long brush 4 is evenly arranged at the notches and the long brush 4 completely covers the notches.

[0039] The enclosure is divided into a main enclosure 1 and a secondary enclosure 2. The side wall of the main enclosure 1 is provided with a lower bracket 6 and an upper bracket 7. The secondary enclosure 2 is spliced ​​to the main enclosure 1 through the lower bracket 6 and the upper bracket 7.

[0040] The left and right sides of the secondary cover 2 are a closed surface and an open surface, respectively. The open surface is not equipped with a wall panel. When the main cover 1 and the secondary cover 2 are spliced ​​together, the open surface of the secondary cover 2 is attached to the main cover 1, and the secondary cover 2 shares the side wall of the main cover 1 to form a closed cover.

[0041] In actual construction, multiple main hoods 1 and multiple auxiliary hoods 2 are freely combined. Depending on the torque conditions of the power mechanism, different schemes such as one-to-one and one-to-two can be realized, which greatly improves the flexibility of the arrangement of the fume hood and the residual electrode tray, while reducing the space occupied by the power mechanism.

[0042] Specifically, the lower bracket 6 is an L-shaped plate with a U-shaped longitudinal section. The lower bracket 6 is fixedly installed from bottom to top at the corner of the bottom of the front side wall of the main cover 1. When the main cover 1 and the secondary cover 2 are spliced, the corner of the bottom of the front side wall of the secondary cover 2 is engaged with the lower bracket 6.

[0043] The upper bracket 7 is formed by bending a rectangular plate, and its longitudinal section is shaped like the letter "Z".

[0044] Specifically, the upper bracket 7 includes an upper horizontal plate 701, a vertical plate 702, and a lower horizontal plate 703. The upper horizontal plate 701 and the lower horizontal plate 703 are integrally formed on the upper and lower ends of the vertical plate 702, respectively. The upper bracket 7 is located at the corner of the upper end of the side wall of the main cover 1. The upper horizontal plate 701 is attached to the outer surface of the upper wall panel of the main cover 1, the vertical plate 702 is attached to the outer surface of the side wall panel of the main cover 1, and the lower horizontal plate 703 is attached to the inner surface of the upper wall panel of the secondary cover 2.

[0045] A connecting piece 5 is assembled between two adjacent pull plates 3.

[0046] The pull plate 3 has a weight reduction hole 301;

[0047] The pull plate connector 5 includes spokes 501, clamping buckles, washers 504, and nuts 505. The clamping buckles are L-shaped and consist of a main clamping buckle 502 and a secondary clamping buckle 503 that engage. After engaging, the main clamping buckle 502 and the secondary clamping buckle 503 form a clamping groove 507, which matches the shape of the pull plate 3. Both the main clamping buckle 502 and the secondary clamping buckle 503 have [features] on their sidewalls adjacent to the clamping groove 507. The device has a slot 506, a main clamping buckle 502 and a secondary clamping buckle 503. The side wall of the clamping buckle and the side wall of the pull plate 3 form a strip groove. Two spokes 501 are respectively embedded in the strip groove and the slot 506. Multiple washers 504 are sleeved on the spokes 501 and multiple nuts 505 are screwed on the spokes 501. The nuts 505 cooperate with the washers 504 to press the main clamping buckle 502 and the secondary clamping buckle 503, so that they hold the pull plate 3 tightly.

[0048] The connection strength between the pull plates 3 is reinforced by the pull plate connector 5, which distributes the burden at the connection between the main cover 1 and the secondary cover 2 during the lifting process. The assembly method is flexible and facilitates the free combination of multiple main covers 1 and multiple secondary covers 2.

[0049] The enclosure is composed of wall panels and a steel frame 9. The wall panels consist of a panel 10 and an insulation layer 11.

[0050] Specifically, the inner and outer sides of the steel frame 9 are fitted with panels 10, and the cavity formed by the steel frame 9 and the panels 10 on both the inner and outer sides is filled with insulation material to form an insulation interlayer 11.

[0051] The side of the lower horizontal plate 703 is integrally formed with a guide wing 704. The guide wing 704 is curved upward and the angle between it and the lower horizontal plate 703 is 160 degrees to 175 degrees. A deformation groove 705 is provided at the connection between the guide wing 704 and the lower horizontal plate 703.

[0052] During the docking process of the main cover 1 and the secondary cover 2, the guide wing 704 can guide the two to come together, reducing the difficulty of hoisting. After the main cover 1 and the secondary cover 2 are docked, the guide wing 704 unfolds under the pressure of the secondary cover 2 and tends to be horizontal.

[0053] Preferably, a short brush 12 is provided at the seam between the main cover 1 and the secondary cover 2.

[0054] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
