Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a smoke and dust collecting hood for a mobile belt conveyor. Background Art

[0002] With the continuous increase in domestic electric arc furnace steelmaking capacity, electric arc furnace steelmaking technology has made significant progress. The capacity of high-efficiency electric arc furnaces has continued to increase, from 80 tons to 150 tons. Currently, electric arc furnaces in operation or under construction are generally 100 tons or above. The maximum transformer capacity used for electric arc furnace smelting has reached 16MVA, the maximum secondary current has reached over 85,000A, the maximum oxygen supply is 3500NM³ / h, the carbon injection rate is 20kg / t steel, and the carbon addition rate reaches 7kg / t steel. The smelting time has been shortened to 33 minutes / furnace. High-strength smelting has led to a surge in the demand for lime and alloys in electric arc furnaces. The traditional method of adding lime and alloys through a hopper via a crane is no longer sufficient for electric arc furnace smelting. A more advanced and intelligent auxiliary material loading system has been developed. The materials are unloaded by trucks into underground silos, then transported by a steep-angle belt to a mobile conveyor. The mobile conveyor then delivers the different types of materials to the corresponding silos.

[0003] As the smelting intensity of electric arc furnaces increases, the amount of auxiliary materials such as lime increases significantly. The mobile belt conveyor in the auxiliary material feeding system takes longer to receive and unload materials, generating a large amount of dust, which is dispersed in the steelmaking workshop and seriously affects the health of workers in the steelmaking workshop and the workshop environment. Related technologies use the method of increasing the capture air volume of the dust removal system to reduce dust, which not only increases the investment in dust removal system equipment and the energy consumption of the dust removal system, but also causes a large amount of dust.

[0004] Therefore, it is necessary to provide a mobile belt conveyor smoke and dust collecting cover. Utility Model Content

[0005] The utility model provides a smoke and dust collecting cover for a mobile belt conveyor to solve the above technical problems.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the present utility model provides a mobile belt conveyor smoke and dust collection hood, including: a cage smoke hood and side baffles fixed on both sides of the bottom edge of the cage smoke hood, a hanging platform is installed on the inner wall of the side baffle close to the bottom surface, the bottom surfaces of the two hanging platforms are both against the top surface of the belt conveyor frame, and grooves are provided at both ends of the hanging platform, and a roller is rotatably connected in the groove, and part of the roller extends to the outside of the groove.

[0007] Furthermore, a plurality of limiting pits are provided on the top surface of the belt conveyor frame, and the roller is suitable for moving into the limiting pits along the belt conveyor frame.

[0008] Furthermore, the cage smoke hood includes two inclined plates and vertical plates fixed at both ends of the two inclined plates, and the side baffles are arranged on the bottom edges of the inclined plates.

[0009] Furthermore, a dust collecting pipe is provided at the connection position of the two inclined plates.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0027] See also Figure 1 , Figure 1 This is a three-dimensional diagram of the best embodiment of a mobile belt conveyor smoke collection cover of the utility model. Figure 1 As shown, at least one embodiment provides a mobile belt conveyor smoke collection hood, comprising: a cage smoke hood 2 and side baffles 1 fixed on both sides of the bottom edge of the cage smoke hood 2, the two side baffles 1 are just used to abut the two sides of the belt conveyor frame 6, and materials can move in the front and rear directions of the cage smoke hood 2. In order to facilitate the installation and movement between the smoke collection hood and the belt conveyor, a hanging platform 5 is installed on the inner wall of the side baffle 1 near the bottom surface. The hanging platform 5 and the side baffle 1 near the bottom part form a right-angle platform, which is used to directly clip into the top corner position of the belt conveyor frame 6, eliminating the bracket installation step. In addition, since the feeding belt conveyor in general steelmaking technology is long, one belt conveyor may need to be equipped with multiple sets of smoke collection hoods, or smoke collection hoods may be needed at different sections. In order to facilitate the movement of the smoke collection hood, grooves 9 are opened at both ends of the hanging platform 5, and rollers 8 are rotatably connected in the grooves 9. The bottom surfaces of the two hanging platforms 5 are both against the top surface of the belt conveyor frame 6 , and the width of the hanging platforms 5 is smaller than the width of the belt conveyor frame 6 .

[0028] Side baffle 1 and cage smoke hood 2

[0029] Please continue reading Figure 1 Combined with Figure 2 , Figure 2 This is a structural diagram of the optimal embodiment of the utility model hanging platform. Figures 1 to 2 As shown, the smoke cage hood 2 includes two inclined plates and vertical plates fixed at both ends of the two inclined plates. The junction of the inclined plates is the highest point. The upward arched design allows the smoke to be concentrated in the center. The side baffle 1 is set at the bottom edge of the inclined plate. A dust collecting pipe 3 is set at the connection position of the two inclined plates. The dust collecting pipe 3 is provided with multiple dust exhaust ports 4. The top of the collection hood adopts a large-capacity design to ensure that the top of the collection hood has sufficient smoke storage volume when dust erupts to avoid dust overflow; the collection hood is arranged in sections to make the collection port closer to the dust source point, thereby improving the dust capture rate. The dust exhaust port 4 is connected to the exhaust device. The inner diameter of the dust exhaust port 4 is 0.3 times the inner diameter of the dust collecting pipe 3.

[0031] Please continue reading Figure 1 and combined Figures 2 to 4 , Figure 3 For this utility model Figure 2 A in the middle is an enlarged structural diagram; Figure 4 This is a three-dimensional diagram of the optimal embodiment of the rubber strip and roller of the utility model. Figures 1 to 4 As shown, grooves 9 are provided at both ends of the hanging platform 5, and rollers 8 are rotatably connected in the grooves 9, with part of the rollers 8 extending outside the grooves 9. The top surface of the conveyor frame 6 is provided with a plurality of limiting pits, and the rollers 8 are suitable for moving along the conveyor frame 6 into the limiting pits. Specifically, when the rollers 8 move into the pits, the rubber strips 7 and the top surface of the conveyor frame 6 are against each other. When the rollers 8 move on the top surface of the conveyor frame 6, there is a certain gap between the rubber strips 7 and the top surface of the conveyor frame 6. The purpose of this design is to facilitate the movement of the collection hood when not in use, and to provide a strong soft contact seal when in use. Multiple rubber strips 7 are provided on the bottom surface of the hanging platform 5. The rubber strips 7 are provided on the bottom of the collection hood for a soft connection, which has a better sealing effect and does not affect the operation of the mobile conveyor. Specifically, the thickness of the rubber strips 7 decreases one by one from the side baffle 1 to the center of the cage smoke hood 2, achieving multiple seals to improve the sealing strength.

[0032] In summary, by providing a hanging platform 5, the installation and disassembly steps of the collection hood are simplified, and the convenience of moving the collection hood is improved; by providing multiple dust exhaust ports 4 on the arched smoke cage hood 2, it is ensured that there is sufficient smoke storage capacity on the top of the collection hood when dust explodes, thereby avoiding dust overflow; the collection hood is arranged in sections so that the collection ports are closer to the dust source point, thereby improving the dust capture rate; by providing multiple rubber strips 7, multiple seals are achieved and the sealing strength is improved.
