Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical environmental protection dust removal equipment, and in particular to a bottom ash unloading device for a silicon manganese dust removal and ash storage tank. Background Technology

[0002] In the production of ferrosilicon manganese, dust collection silos are used to collect dust generated during the production process, and bottom unloading is a critical and challenging workflow. Traditional unloading methods have many drawbacks: operators need to stand on the bottom platform of the dust collection silo for extended periods, frequently manually opening and closing the slide gate valve. Due to the narrow space and complex environment at the bottom of the silo, this frequent manual operation is not only labor-intensive but also prone to causing safety accidents due to operational errors. Since dust collection silos are typically huge, such as 80-ton silos, if personnel are working underneath them and the silo malfunctions, such as structural damage or material leakage, it poses a serious threat to their lives. If operators monitor the silo for extended periods, they will be in a high-concentration dust environment, and long-term inhalation of dust can easily lead to occupational diseases such as pneumoconiosis, which does not meet occupational health requirements and harms the health of employees. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a bottom unloading device for a silicon-manganese dust collector and ash storage tank, which solves the problem of high personnel safety risks and significant occupational health hazards caused by the need for personnel to frequently manually open and close the gate valve in the narrow and complex space at the bottom of the dust collector and ash storage tank during the existing manual unloading process.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A bottom unloading device for a silicon-manganese dust removal and ash storage tank includes a support column, a support platform installed on the support column, a dust removal and ash storage tank installed on the support platform, an unloading pipe and a support frame installed at the bottom of the dust removal and ash storage tank, and an electric hydraulic gate valve installed on the unloading pipe.

[0005] As a further improvement of this utility model, the ash discharge pipe is a two-section pipe structure. The first section of the ash discharge pipe is installed perpendicular to the ground, and the second section of the ash discharge pipe is installed inclined to the ground. An electric hydraulic sector valve is installed on the second section of the ash discharge pipe.

[0006] As a further improvement of this utility model, the electro-hydraulic gate valve includes a first hydraulic cylinder and a gate valve housing. A gate is movably inserted into the gate valve housing. A first hydraulic push rod is hinged to one side of the gate. The first hydraulic push rod is fitted into the first hydraulic cylinder. The first hydraulic cylinder is movably hinged to a support frame.

[0007] As a further improvement of this utility model, the electric hydraulic sector valve includes a sector valve housing, which is installed on the ash discharge pipe. A fixed seat is installed on the outer side of the sector valve housing, and a sector plate is installed on the fixed seat. A baffle is installed perpendicular to the sector plate and is vertically inserted into the ash discharge pipe. A second hydraulic push rod is movably hinged to the outer side of the sector plate. The second hydraulic push rod is installed in a second hydraulic cylinder, which is movably hinged to a support frame.

[0008] As a further improvement of this utility model, stiffening plates are welded to the fan-shaped plate, and the second hydraulic push rod is movably hinged to the stiffening plates. As a further improvement of this utility model, a ladder is provided on one side of the support column. As a further improvement of this utility model, a guardrail is provided at the edge of the support platform.

[0009] As a further improvement of this utility model, the signal control terminal of the electrical control cabinet is connected to the signal receiving terminal of the electro-hydraulic gate valve; the signal control terminal of the electrical control cabinet is connected to the signal receiving terminal of the electro-hydraulic sector valve.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This device uses support columns and support platforms to stably raise the dust collection and ash storage tank. An electric hydraulic gate valve is installed on the bottom ash discharge pipe. The support frame enhances the structural stability. Compared with the existing manual ash discharge method, it eliminates the need for personnel to frequently manually open and close the gate valve in the narrow and complex space at the bottom of the dust collection and ash storage tank. Ash discharge can be achieved by mainly controlling the opening and closing of the electric hydraulic gate valve, which greatly reduces the exposure time in dust, significantly improves the working environment, and reduces occupational health hazards.

[0011] 2. The ash discharge pipe is designed with a two-section structure. The first section is installed perpendicular to the ground, allowing the ash to fall quickly and be transported in a concentrated manner using gravity, preventing ash from accumulating inside the pipe. The second section is installed at an angle to the ground, ensuring a smooth connection to subsequent conveying stages and reducing the possibility of ash accumulation and blockage. An electric hydraulic sector valve is installed on the second section of the ash discharge pipe, which not only achieves reliable shut-off and leak-proof sealing, but also allows for flexible adjustment of the ash discharge speed, reducing secondary dust generation, further improving the automation and continuity of ash discharge, and reducing the difficulty of operation and maintenance.

[0012] 3. The electro-hydraulic sector valve stably mounts the sector valve housing onto the ash discharge pipe, and the fixed base effectively supports the sector plate. The baffle, which is perpendicular to the sector plate, is vertically inserted into the ash discharge pipe, which can control the opening and closing of the ash discharge pipe and the amount of ash discharged. At the same time, one end of the second hydraulic push rod is movably hinged to the stiffening plate welded to the sector plate, and the other end is installed in the second hydraulic cylinder movably hinged to the support frame. This not only enables the flexible rotation of the sector plate by hydraulic drive, but also enhances the structural strength of the sector plate when it is subjected to continuous pushing and pulling through the stiffening plate.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figs. 1-3 As shown, a bottom unloading device for a silicon-manganese dust collector ash storage tank includes a support column 3, a support platform 2 mounted on the support column 3, and a dust collector ash storage tank mounted on the support platform 2. An unloading pipe 4 and a support frame 50 are installed at the bottom of the dust collector ash storage tank 1. An electric hydraulic gate valve 5 is installed on the unloading pipe 4. This device securely raises the dust collector ash storage tank 1 through the support column 3 and support platform 2. The electric hydraulic gate valve 5, installed on the bottom unloading pipe 4, enhances structural stability in conjunction with the support frame 50. Compared to existing manual unloading methods, it eliminates the need for personnel to frequently manually open and close the gate valve in the narrow and complex space at the bottom of the dust collector ash storage tank 1. Unloading operations can be achieved by controlling the opening and closing of the electric hydraulic gate valve 5, significantly reducing exposure time in dust, significantly improving the working environment, and reducing occupational health hazards.

[0017] The ash discharge pipe 4 is a two-section pipe structure. The first section of the ash discharge pipe 4 is installed perpendicular to the ground, while the second section is installed at an angle to the ground. An electro-hydraulic sector valve 6 is installed on the second section of the ash discharge pipe 4. The two-section structure of the ash discharge pipe 4, with the first section installed perpendicular to the ground, allows the ash to fall quickly and be transported in a concentrated manner using gravity, avoiding ash stagnation in the pipe. The second section installed at an angle to the ground can smoothly connect to subsequent conveying links, reducing the possibility of ash accumulation and blockage. The electro-hydraulic sector valve installed on the second section of the ash discharge pipe 4 not only achieves reliable shut-off and leak-proof sealing, but also allows for flexible adjustment of the ash discharge speed, reducing secondary dust generation, further improving the automation and continuity of ash discharge, and reducing the difficulty of operation and maintenance.

[0018] The electro-hydraulic sector valve 6 includes a sector valve housing 68, which is mounted on the ash discharge pipe 4. A fixing seat 67 is mounted on the outer surface of the sector valve housing 68, and a sector plate 60 is mounted on the fixing seat 67. A baffle 601 is mounted perpendicular to the sector plate 60 and is vertically inserted into the ash discharge pipe 4. A second hydraulic push rod 63 is movably hinged to the outer surface of the sector plate 60. The second hydraulic push rod 63 is fitted into a second hydraulic cylinder 62, which is movably hinged to a support frame 50. A stiffening plate 65 is welded to the sector plate 60, and the second hydraulic push rod 63 is movably hinged to the stiffening plate 65. The fan-shaped valve 6 is stably installed on the ash discharge pipe 4 by the fan-shaped valve housing 6, and the fixed seat 67 effectively supports the installation of the fan-shaped plate 60. The baffle 601, which is set perpendicular to the fan-shaped plate 60, is vertically inserted into the ash discharge pipe 4, which can accurately control the opening and closing of the ash discharge pipe 4 and the amount of ash discharged. At the same time, one end of the second hydraulic push rod 63 is movably hinged to the stiffening plate 65 welded to the fan-shaped plate 60, and the other end is installed in the second hydraulic cylinder 62, which is movably hinged to the support frame 50. This not only realizes the flexible rotation of the fan-shaped plate 60 to drive the baffle 601 to open and close by hydraulic drive, but also enhances the structural strength of the fan-shaped plate 60 when it is subjected to continuous pushing and pulling by the stiffening plate 65.

[0019] In use: The ash material in the silicon-manganese dust collector ash storage tank first enters the ash discharge pipe 4 at the bottom of the dust collector ash storage tank 1. At this time, the electric hydraulic gate valve 5 installed on the ash discharge pipe 4 is first controlled to open, providing a channel for ash material transportation. Since the ash discharge pipe 4 has a two-section structure, the first section of the pipe is perpendicular to the ground. The ash material falls quickly in the first section of the ash discharge pipe 4 by its own gravity and is concentratedly transported, effectively avoiding ash material retention in the pipe. Then, the ash material smoothly enters the second section of the ash discharge pipe 4, which is inclined to the ground. This inclined design can smoothly connect the subsequent transportation links and reduce the accumulation and blockage of ash material. Then, the electric hydraulic sector valve 6 installed on the second section of the ash discharge pipe 4 is operated to drive the first section of the ash discharge pipe 4, which is movably hinged to the support frame 50. Two hydraulic cylinders 62 cause the second hydraulic push rod 63, which is installed inside the second hydraulic cylinder 62, to extend and retract. Since the second hydraulic push rod 63 is movably hinged to the stiffening plate 65 welded to the sector plate 60, and the sector plate 60 is installed on the outer side of the sector valve housing 68 of the electric hydraulic sector valve 6 through the fixed seat 67, the extension and retraction of the second hydraulic push rod 63 will drive the sector plate 60 to rotate flexibly around the fixed seat 67, thereby driving the baffle 601 to open, and the ash material will be discharged along the second section of the ash discharge pipe 4. During the ash discharge process, the rotation angle of the sector plate 60 can be controlled by adjusting the extension and retraction of the second hydraulic push rod 63, thereby adjusting the opening and closing degree of the baffle 601 in the ash discharge pipe 4, and realizing flexible adjustment of the ash discharge speed.
