Description

Technical Field

[0001] This utility model relates to the field of sintering and conveying technology, and in particular to a dust sealing cover for the tail of a gas-fired belt conveyor. Background Technology

[0002] A sintering plant is a facility in the metallurgical industry where sintering processes are carried out, primarily providing refined raw materials for blast furnace smelting. It involves batching, mixing, and granulating raw materials such as iron concentrate powder, flux, and fuel to form sinter, which is then ignited and burned. High temperatures promote mineral oxidation and the formation of a liquid phase, ultimately cooling and agglomerating the sinter into blocky sinter. Sintering plants process lean iron ore beneficiation products, rich iron ore powder, and iron-containing waste, sintering them into blocks using belt sintering machines with ignition and ventilation. The resulting products are characterized by uniform particle size, high porosity, and moderate strength. During sintering, belt conveyors are used for rapid material transfer.

[0003] However, the existing equipment has the following shortcomings: When the existing equipment is in use, dust can easily overflow through the gaps in the protective cover connected to the channel. Over time, the dust can easily adhere to the outer surface of the equipment, causing environmental pollution around the equipment.

[0004] Therefore, we propose a dust sealing cover for the tail gas of a 7-belt conveyor to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, which is that material falling during equipment transfer easily generates dust and pollutes the surrounding environment. Therefore, a dust sealing cover for the tail of a gas-fired belt conveyor is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust sealing cover for the tail gas of a seven-phase conveyor belt, comprising a channel, a protective cover, a conveyor belt, a power unit, and a dust collection device. The protective cover is fixedly connected to one end of the channel, the conveyor belt is installed inside the channel, the power unit is fixedly connected to the outer surface of the channel, and the dust collection device is installed at the upper end of the protective cover. The dust collection device includes a connecting plate and a dust collection hopper. The connecting plate is installed inside the upper end of the protective cover, the dust collection hopper is fixedly connected to the upper end of the connecting plate, and a connecting pipe is fixedly connected to the upper end of the dust collection hopper. A housing is fixedly connected to the end of the connecting pipe away from the dust collection hopper, and a discharge pipe is fixedly connected to the end of the housing away from the connecting pipe.

[0007] Furthermore, a rotating sleeve is fixedly connected inside the outer shell, and a connecting shaft is rotatably connected inside the rotating sleeve. By setting the rotating sleeve, the rotating sleeve reduces the rotational friction of the connecting shaft, ensuring that the impeller outputs negative pressure stably.

[0008] Furthermore, a wind turbine is fixedly connected to the surface of the connecting shaft, and a motor is fixedly connected to one end of the connecting shaft.

[0009] Furthermore, the motor is fixedly connected to the surface of the housing. The motor is a servo motor, which can control the speed. The negative pressure intensity can be adjusted by changing the speed of the impeller. When the material moisture is low and the amount of dust is large, the speed is increased to enhance the suction. When the amount of dust is small, the speed is reduced to save energy, thus balancing the dust removal effect and economy.

[0010] Furthermore, a moving device is fixedly installed on the surface of the connecting plate. The moving device includes a mounting arm and a telescopic rod. The mounting arm is fixedly connected to the upper surface of the connecting plate, and the telescopic rod is fixedly connected to the lower end of the mounting arm. A cylinder is fixedly connected to the lower end of the telescopic rod, and a mounting head is fixedly connected to the lower surface of the cylinder. A limit block is fixedly connected to the surface of the cylinder. The cylinder is a synchronous cylinder, which can perform synchronous and precise movement. The extension and retraction of the cylinder can be automatically controlled by a program, and the response is rapid.

[0011] Furthermore, the limiting block is fixedly connected to the outer surface of the protective cover, and a contact ring is fixedly connected to the lower end of the connecting plate. The contact ring slides synchronously with the connecting plate. Its material is wear-resistant rubber, which fits tightly against the inner wall of the protective cover, enhancing the sealing performance and reducing the leakage of smoke and dust from the gap between the connecting plate and the protective cover.

[0012] Furthermore, the contact ring is slidably connected inside the protective cover.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a dust collection device is installed to effectively absorb dust generated by materials, thereby reducing the problem of dust easily overflowing through gaps in the protective cover connected to the channel during the use of existing equipment, which causes environmental pollution around the equipment. This dust collection device achieves dust absorption and improves the environmental protection of the equipment.

[0014] In this invention, by setting up a moving device, when the position of the dust collection device is adjusted, the cylinder extension end is activated to drive the extension rod and the mounting arm to move up and down, thereby causing the connecting plate and the dust collection hopper to rise and fall within the protective cover. Adjusting the height of the dust collection hopper can adapt to material layers of different thicknesses or conveyor belt movement, ensuring the optimal distance between the dust collection hopper and the dust source, and improving collection efficiency.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-5 This utility model provides a technical solution: a dust sealing cover for the tail of a gas conveyor belt, including a channel 1, a protective cover 2, a conveyor belt 3, a power unit 4, and a dust collection device 5. The protective cover 2 is fixedly connected to one end of the channel 1, the conveyor belt 3 is installed inside the channel 1, and the power unit 4 is fixedly connected to the outer surface of the channel 1.

[0020] Channel 1 is a steel frame structure, which provides stable support and is wear-resistant; the protective cover 2 is a metal cover with excellent sealing performance, which can effectively block the spread of smoke and dust; the conveyor belt 3 is a high-strength wear-resistant rubber belt, which can stably transport materials; the power unit 4 is a high-efficiency drive device that provides continuous power to the conveyor belt 3.

[0021] The following section will describe in detail the specific setup and function of its vacuuming device 5 and moving device 6.

[0022] In this embodiment: the dust collection device 5 is installed on the upper end of the protective cover 2. The dust collection device 5 includes a connecting plate 51 and a dust collection hopper 52. The connecting plate 51 is installed inside the upper end of the protective cover 2. The dust collection hopper 52 is fixedly connected to the upper end of the connecting plate 51. A connecting pipe 53 is fixedly connected to the upper end of the dust collection hopper 52. A housing 54 is fixedly connected to the end of the connecting pipe 53 away from the dust collection hopper 52. A discharge pipe 56 is fixedly connected to the end of the housing 54 away from the connecting pipe 53.

[0023] Specifically, a rotating sleeve 57 is fixedly connected inside the outer casing 54, and a connecting shaft 58 is rotatably connected inside the rotating sleeve 57.

[0024] In this embodiment: by setting a rotating sleeve 57, the rotating sleeve 57 reduces the rotational friction of the connecting shaft 58, ensuring that the impeller 59 outputs negative pressure stably.

[0025] Specifically, a fan wheel 59 is fixedly connected to the surface of the connecting shaft 58, and a motor 55 is fixedly connected to one end of the connecting shaft 58.

[0026] Specifically, the motor 55 is fixedly connected to the surface of the housing 54. The motor 55 is a servo motor, which can control the speed. The negative pressure intensity can be adjusted by changing the speed of the impeller 59. When the material moisture is low and the amount of dust is large, the speed is increased to enhance the suction. When the amount of dust is small, the speed is reduced to save energy, thus balancing the dust removal effect and economy.

[0027] In this embodiment: a moving device 6 is fixedly provided on the surface of the connecting plate 51. The moving device 6 includes a mounting arm 61 and a telescopic rod 62. The mounting arm 61 is fixedly connected to the upper surface of the connecting plate 51, and the telescopic rod 62 is fixedly connected to the lower end of the mounting arm 61. A cylinder 63 is fixedly connected to the lower end of the telescopic rod 62. A mounting head 64 is fixedly connected to the lower end surface of the cylinder 63, and a limit block 65 is fixedly connected to the surface of the cylinder 63.

[0028] In this embodiment, cylinder 63 is a synchronous cylinder, which can move synchronously and precisely. The extension and retraction of cylinder 63 can be automatically controlled by a program, and the response is rapid.

[0029] Specifically, the limiting block 65 is fixedly connected to the outer surface of the protective cover 2, and the lower end of the connecting plate 51 is fixedly connected to the contact ring 66. The contact ring 66 slides synchronously with the connecting plate 51. Its material is wear-resistant rubber, which fits tightly with the inner wall of the protective cover 2 to enhance the sealing and reduce the leakage of smoke and dust from the gap between the connecting plate 51 and the protective cover 2.

[0030] Specifically, the contact ring 66 is slidably connected inside the protective cover 2.

[0031] Working Principle: During operation, the conveyor belt 3, driven by the power unit 4, transports materials such as coal and ore. Material falling or rubbing at the tail end generates a large amount of smoke and dust. The protective cover 2 covers the end of the channel 1, forming a relatively enclosed space to prevent the direct spread of smoke and dust. Then, the motor 55 is started, driving the connecting shaft 58 to rotate at high speed within the rotating sleeve 57. This drives the impeller 59 to rotate, creating negative pressure in the connecting pipe 53. Under this negative pressure, the dust collection hopper 52 draws the smoke and dust from the protective cover 2, which is then transported to the outer shell 54 via the connecting pipe 53. The smoke and dust are further guided by the impeller 59 within the outer shell 54 and finally discharged outside the equipment through the discharge pipe 56. By installing the dust collection device 5, the dust generated by the materials is effectively absorbed, reducing the problem of dust easily overflowing through gaps in the protective cover 2 connected to the channel 1 during operation, thus preventing environmental pollution around the equipment. This dust collection device 5 effectively absorbs dust and improves the equipment's environmental protection.

[0032] When the equipment adjusts the position of the dust collection device 5, the cylinder 63 is activated to drive the telescopic rod 62 and the mounting arm 61 to move up and down, which in turn drives the connecting plate 51 and the dust collection hopper 52 to rise and fall within the protective cover 2. Adjusting the height of the dust collection hopper 52 can accommodate material layers of different thicknesses or the movement of the conveyor belt 3, ensuring that the distance between the dust collection hopper 52 and the dust source is optimal and improving collection efficiency.

[0033] The above description discloses only one or more preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present utility model still fall within the scope of the present utility model.
