[0040] The smoke hood body 20 includes a first side wall and a second side wall arranged on the two sides of the anode furnace 200 respectively, the first side wall and the second side wall are parallel to the axis of the anode furnace 200, and the first side wall and the second side wall are arranged at intervals from the outer wall of the anode furnace 200, so that a collection channel 201 is formed on each side of the anode furnace 200, and two downwardly arranged collection ports 202 are formed; correspondingly, the smoke collecting device 10 is also provided with two smoke collecting devices 10, and the two smoke collecting devices 10 are arranged on the two sides of the anode furnace 200 respectively, and are used for collecting the dust falling from the two collection ports 202.

[0041] In some embodiments, as shown in Figure 2 and Figure 3As shown, the mounting frame 1 comprises a first frame 11 and a second frame 12 connected with each other, the first frame 11 encloses a first mounting slot 111, the second frame 12 encloses a second mounting slot 121, the first mounting slot 111 is arranged at the lower side of the collecting port 202, and the second mounting slot 121 is arranged at the outer side of the chimney body 20; in the closed state, the dust collecting part 21 is arranged in the first mounting slot 111, and in the open state, the dust collecting part 21 is arranged in the second mounting slot 121.

[0042] Through the above arrangement, the first frame 11 and the second frame 12 can provide support for the dust collecting plate 2, maintain the stability of the dust collecting plate 2 in the closed state and the open state; at the same time, in the closed state, the dust collecting part 21 is arranged in the first mounting slot 111, and the smoke dust can fall on the dust collecting part 21 through the first mounting slot 111 to achieve smoke dust collection, and in the open state, the dust collecting part 21 is arranged in the second mounting slot 121, and the staff can clean the accumulated smoke dust on the dust collecting part 21 through the second mounting slot 121.

[0043] As an example, as shown in Figures 2-4 The first frame 11 and the second frame 12 are both welded by a plurality of shaped steels, one part of the shaped steels is a first shaped steel 131, and the other part of the shaped steels is a second shaped steel 132, the first shaped steel 131 is a channel steel, and the second shaped steel 132 is an angle steel; the number of the first shaped steels 131 is two, the number of the second shaped steels 132 is multiple, the first shaped steels 131 extend along the radial direction of the anode furnace 200, the second shaped steels 132 extend along the axial direction of the anode furnace 200, that is, the first shaped steels 131 and the second shaped steels 132 are perpendicular to each other, and the two first shaped steels 131 are respectively arranged at two ends of the multiple second shaped steels 132; the multiple second shaped steels 132 are divided into three groups, the three groups of second shaped steels 132 are arranged outward along the radial direction of the anode furnace 200 in sequence, and are sequentially a first group 133, a second group 134, and a third group 135, thereby forming the first frame 11 and the second frame 12, and both ends of the multiple second shaped steels 132 are welded and fixed with the two first shaped steels 131 to ensure the stability of the mounting frame 1.

[0044] As shown in Figure 2 and Figure 4 The number of the second shaped steels 132 in the first group 133 and the second group 134 is two, and the two second shaped steels 132 in the same group are arranged in an upper and lower interval to form a sliding channel for the sliding of the dust collecting plate 2.

[0045] The number of the second shaped steels 132 in the third group 135 is one, and the height of the second shaped steel 132 in the third group 135 matches the height of the second shaped steel 132 on the lower side of the second group 134, thereby being more conducive to pulling the dust collecting plate 2 outward and improving the operation convenience of switching the dust collecting plate 2 from the closed state to the open state.

[0046] In some embodiments, as shown in Figure 4 andFigure 5 As shown, the mounting frame 1 further comprises a slide rail 14, the slide rail 14 comprises a first sliding part, the dust collecting plate 2 comprises a second sliding part, and the first sliding part and the second sliding part are in sliding cooperation.

[0047] By arranging the slide rail 14, the slide rail 14 can provide support for the dust collecting plate 2 during the sliding process, thereby improving the stability of the smoke dust collecting system during use.

[0048] As an example, as shown in Figure 4 and Figure 5 , the slide rail 14 comprises a first plate 141 and a second plate 142, the first plate 141 is horizontally arranged, and the second plate 142 is arranged on the upper side of the first plate 141 and is vertically arranged, the upper side of the first plate 141 and the vertical side of the second plate 142 form a right angle groove, which is the first sliding part mentioned above, and the edge part of the dust collecting plate 2 is the second sliding part mentioned above, and the second sliding part is in sliding cooperation with the first sliding part.

[0049] The upper side of the first plate 141 provides support for the dust collecting plate 2, and the vertical side of the second plate 142 provides limiting for the dust collecting plate 2, thereby improving the stability of the sliding of the dust collecting plate 2.

[0050] Optionally, as shown in Figure 5 , the mounting frame 1 further comprises a plurality of rib plates 15, and the rib plates 15 are arranged on the lower side of the slide rail 14.

[0051] In this way, the strength of the slide rail 14 can be increased, thereby ensuring the overall strength of the mounting frame 1.

[0052] In other embodiments, auxiliary components such as rollers can be installed on the dust collecting plate 2 or the mounting frame 1, so that the sliding of the dust collecting plate 2 is smoother.

[0053] In some embodiments, as shown in Figure 4 and Figure 5 , the number of slide rails 14 is multiple, at least one slide rail 14 is a first slide rail, at least one slide rail 14 is a second slide rail, and the first slide rail and the second slide rail are oppositely arranged on both sides of the dust collecting plate 2 along the axial direction of the anode furnace 200.

[0054] The two sides of the dust collecting plate 2 are respectively in sliding cooperation with the first slide rail and the second slide rail, which can further improve the stability of the sliding of the dust collecting plate 2.

[0055] In some embodiments, the number of dust collecting plates 2 is multiple, and the multiple dust collecting plates 2 are arranged in sequence along the axial direction of the anode furnace 200.

[0056] Due to different specifications of the smoke hood body 20, if the length of the smoke hood body 20 extending along the anode furnace 200 in the axial direction is relatively long, the number of the dust collecting plates 2 can be adjusted according to the actual size of the smoke hood body 20; by arranging a plurality of dust collecting plates 2, the phenomenon that the dust collecting plate 2 is too large in size and the smoke dust accumulated on the dust collecting plate 2 is too heavy, thereby causing the dust collecting plate 2 to be difficult to slide or to be deformed, can be prevented.

[0057] As an example, as shown in Figure 4 and Figure 5 , the number of the dust collecting plates 2 is two, and correspondingly, the middle position of the second section steel 132 is welded with a slide rail 14, which is a middle slide rail 143, the middle slide rail 143 can increase the stability of the mounting frame 1, at the same time, the middle slide rail 143 uniformly divides the first mounting groove 111 and the second mounting groove 121 into two parts for the sliding of the two dust collecting plates 2.

[0058] The number of the slide rails 14 is three, one of which is the above-mentioned middle slide rail 143, and the other two are end slide rails 144, and the two end slide rails 144 are arranged close to the two first section steels 131 respectively; the two sides of the middle slide rail 143 are respectively in sliding cooperation with the two dust collecting plates 2; thus, the two sides of the dust collecting plate 2 are respectively in sliding cooperation with the end slide rail 144 and the middle slide rail 143, so as to ensure the stability of the dust collecting plate 2, thereby improving the stability of the dust collecting plate 2 in the process of collecting smoke dust and cleaning.

[0059] In some embodiments, as shown in Figure 2 , the mounting frame 1 is provided with a first limiting part 31, and the dust collecting plate 2 is provided with a second limiting part 32, the second limiting part 32 is arranged on the side of the first limiting part 31 away from the anode furnace 200, in the closed state, the first limiting part 31 is attached to the second limiting part 32, and the dust collecting plate 2 has a gap with the outer wall of the anode furnace 200.

[0060] Through the above arrangement, when the first limiting part 31 is attached to the second limiting part 32, it indicates that the dust collecting plate 2 has been switched to the closed state, and the smoke dust in the flue gas of the anode furnace 200 can be collected, thereby limiting the sliding position of the dust collecting plate 2, preventing the dust collecting plate 2 from sliding too far towards the anode furnace 200 and touching the outer wall of the anode furnace 200, thereby ensuring the normal rotation of the anode furnace 200.

[0061] As an example, as shown in Figure 2 , the first limiting part 31 is the upper second section steel 132 of the second group 134, and the second limiting part 32 is a limiting plate, and the first limiting part 31 and the second limiting part 32 are limited by face attachment, thereby further improving the stability of the dust collecting plate 2 in the closed state.

[0062] In some embodiments, as shown in Figure 2As shown, the smoke dust collecting device 10 further comprises a mounting seat 4 connected with the smoke hood body 20, and the mounting frame 1 is detachably connected with the mounting seat 4.

[0063] Through the above arrangement, the mounting seat 4 provides a mounting base for the smoke dust collecting device 10, and the mounting frame 1 is convenient to disassemble and assemble with the mounting seat 4, which is more conducive to the installation, maintenance and other operations of the smoke dust collecting device 10.

[0064] For example, the mounting seat 4 is in the form of a plate, and the number of the mounting seat 4 is two. The two mounting seats 4 are arranged on the two sides of the smoke hood body 20 along the axial direction of the anode furnace 200, and are both welded with the smoke hood body 20. The lower side of the mounting seat 4 is basically flush with the lower side of the smoke hood body 20. The two first type steels 131 of the mounting frame 1 are respectively fixed with the two mounting seats 4 through a plurality of bolts. After the mounting frame 1 is assembled with the mounting seat 4, the upper side of the mounting frame 1 (i.e. the upper side of the second type steel 132 located on the upper side) is attached with the lower side of the smoke hood body 20, so as to ensure the sealing performance of the connection between the smoke dust collecting device 10 and the smoke hood body 20.

[0065] In some embodiments, as shown in the drawings, Figure 2 The mounting seat 4 has a first stop surface arranged downwardly, and the mounting frame 1 has a second stop surface arranged upwardly. A sealing element 5 is arranged between the first stop surface and the second stop surface, and the first stop surface and the second stop surface are both stopped on the sealing element 5.

[0066] The sealing element 5 is filled between the mounting seat 4 and the mounting frame 1, which can prevent the smoke gas from leaking from the gap between the mounting seat 4 and the mounting frame 1, so as to improve the sealing performance of the smoke dust collecting device 10.

[0067] Optionally, the sealing element 5 is made of refractory fiber cloth.

[0068] The refractory fiber cloth has the advantages of high temperature resistance, corrosion resistance, plasticity and the like, and can maintain stable physical and chemical properties in a high temperature environment and is not easy to deform or fail.

[0069] In addition, the sealing element 5 can also be arranged at other positions of the connection between the smoke dust collecting device 10 and the smoke hood body 20, as long as it can improve the sealing performance of the smoke dust collecting device 10 and the smoke hood body 20.

[0071] By setting the handle 221, the staff can manually control the dust collecting plate 2 to slide, so that the dust collecting plate 2 is switched between the closed state and the open state, so as to collect smoke dust and clean smoke dust.

[0072] By setting the lifting ring 222, the dust collecting plate 2 can be hoisted using a tool such as an electric guide chain to control the dust collecting plate 2 to slide, thereby improving the convenience of operation.

[0073] By setting the driving part, the automatic sliding of the dust collecting plate 2 can be realized without the help of external tools, thereby further improving the convenience of operation.

[0074] Optionally, the driving part is an electric push rod, a gas cylinder or a hydraulic cylinder.

[0075] As shown in the figure, Figure 3 When the dust collecting plate 2 is in the closed state, the dust collecting part 21 is arranged in the first mounting groove 111, and the operation part 22 is arranged in the second mounting groove 121; the two sides of the operation part 22 are provided with the handle 221 and the two lifting rings 222, and the two lifting rings 222 are arranged on the two sides of the handle 221 along the axial direction of the anode furnace 200; the dust collecting plate 2 is hoisted through the two lifting rings 222, so that the dust collecting plate 2 is hoisted more stably.

[0076] As shown in the figure, Figure 1 The smoke cover 100 of the embodiment of the utility model comprises a smoke cover body 20 and the smoke dust collecting device 10 of any one of the above-mentioned embodiments, and the smoke dust collecting device 10 is connected with the smoke cover body 20.

[0077] The smoke cover 100 of the embodiment of the utility model, by setting the smoke dust collecting device 10, can collect the solid particulate matters such as smoke dust in the flue gas discharged by the anode furnace 200; when the anode furnace 200 is in normal production, the dust collecting plate 2 is in the closed state, the flue gas is conveyed upwards to the heat exchanger 300 through the smoke cover body 20, the smoke dust in the flue gas falls and drops on the dust collecting part 21 through the collecting opening 202, and the dust collecting part 21 can temporarily store the smoke dust, so that the collection of the smoke dust is realized; when the smoke dust on the dust collecting plate 2 is accumulated to a certain amount, the dust collecting plate 2 can be pulled outwards along the radial direction of the anode furnace 200 so that the dust collecting part 21 moves to the outside of the smoke cover body 20, and the smoke dust on the dust collecting part 21 is cleaned manually, so that the smoke dust in the flue gas is prevented from being discharged to the external environment, and the workshop environment is protected.
