Description

Technical Field

[0001] The utility model belongs to the technical field of smelting equipment, and particularly relates to a plugging machine. Background Art

[0002] During the smelting process of an industrial silicon ore-blast furnace, when the smelted silicon liquid fills the outlet bag or the silicon water discharge reaches the required process rhythm time point, the furnace eye needs to be promptly blocked, either manually or using related plugging equipment. This operation is called eye blocking. Currently, the main methods for plugging the eyes of industrial silicon ore-blast furnaces are manual plugging and arc-track plugging machines. Manual plugging generally involves two teams of 4-6 people: feeding the plugging material and pushing the plugging material. The feeding team is responsible for feeding the plugging material into the chute using a long-pole shovel, while the pushing team is responsible for pushing the plugging material into the furnace outlet channel using a long-pole plug. The arc-track plugging machine travels along a pre-set curved track on the furnace outlet platform. Before plugging, the plugging material is manually installed, and then the operating equipment delivers the plugging material into the furnace outlet channel, completing the plugging.

[0003] Due to the spatial layout of industrial silicon submerged arc furnaces when they were first built, most submerged arc furnace platforms currently lack space for installing curved track-type eye-blocking machines. Even if space were available to add a new curved track-type eye-blocking machine, it would directly affect production rhythm and increase fixed asset investment. As a result, the current eye-blocking operation of the furnace still relies mainly on manual coordination. Manual coordination of eye-blocking has the disadvantages of requiring a relatively large number of personnel, high labor intensity, and high risk factors. Utility Model Content

[0004] In response to the current technical problems, the utility model aims to provide a plugging machine, which can solve the problem that there is no space for a new arc-track plugging machine on the discharge platform of an industrial silicon ore-fired furnace.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The crawler chassis is a commercial product. By providing a slewing support on the crawler chassis, the slewing operation of the plugging device is achieved, which facilitates the adjustment of the plugging device to the appropriate angle for the plugging operation. By providing a crawler chassis at the bottom of the plugging device, the free movement and movement of the entire machine are achieved. When the plugging machine is working, the output end of the plugging material conveying part and the outer end of the first working rod are both facing the ore furnace. The plugging material is delivered to the furnace eye chute of the ore furnace through the plugging material conveying part.

The plugging machine of the utility model does not need to be provided with an arc track on the outer furnace discharge operation platform of the industrial silicon ore furnace.

DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0027] like Figure 1As shown, a plugging machine according to this embodiment includes a plugging device 1, a crawler chassis 2, a mounting platform 3 mounted on top of the crawler chassis 2, and a control system 8. The control system 8 is electrically connected to the power units of the plugging device 1 and the crawler chassis 2. The mounting platform 3 is fixedly connected to the crawler chassis 2 via a slewing support 4. The mounting platform 3 has a circle of tapped holes on its bottom and is connected to the slewing support 4 via assembly bolts. The plugging device 1 is mounted on the mounting platform 3, and the slewing support 4 is provided to enable the plugging device 1 to rotate.

[0028] The crawler chassis 2 is an existing commercial product, such as Figure 2 and Figure 3 As shown, the crawler chassis 2 includes an intermediate frame 201 and left and right crawler tracks 202 and 203 mounted on either side of the intermediate frame 201. A slewing support 4 is mounted on top of the intermediate frame 201, providing the crawler chassis 2 with free-range travel. Four pivotally connected support devices 5 are symmetrically mounted on the front and rear sides of the intermediate frame 201, enabling the machine to be raised and lowered. The support devices 5 comprise a cylinder 501, a support base 502, and a support housing 503. The cylinder 501 is located within the space enclosed by the support housing 503. One end of the cylinder 501 and the support housing 503 are hingedly connected to the intermediate frame 201 at different locations. The output end of the cylinder 501 and the other end of the support housing 503 are hingedly connected to the support base 502 at the same location. When the output end of the cylinder 501 extends outward, the support housing 503 pivots downward, supporting the support base 502 on the ground, thereby maintaining a certain distance between the intermediate frame 201 and the ground. When the output end of the oil cylinder 501 contracts inward, the support shell 503 rotates upward to separate the support base plate 502 from the ground, thereby reducing the distance between the intermediate frame 201 and the ground.

[0029] like Figure 4As shown, the eye plugging device 1 includes a mounting base 101, a slide rod 102 slidably connected to the mounting base 101, a first working rod 103 arranged at the outer end of the slide rod 102, a first feed trough 104 arranged above the mounting base 101, a second working rod 105 slidably connected to the first feed trough 104, a second feed trough 106 arranged above the first feed trough 104, a third working rod 107 slidably connected to the second feed trough 106, a first power unit, a second power unit and a third power unit, and the first power unit, the second power unit and the third power unit all adopt cylinders. The first working rod 103, the first feed trough 104 and the second feed trough 106 are parallel to each other along the longitudinal axis, the first feed trough 104 is located directly above the first working rod 103, the second feed trough 106 is located directly above the first feed trough 104, and one end of the first feed trough 104 is located below the end of the second feed trough 106. The output end of the first power unit is connected to the slide rod 102, which moves back and forth along the length of the mounting base 101 under the drive of the first power unit. The output end of the second power unit is connected to the second working rod 105, which moves back and forth along the length of the first feeding trough 104 under the drive of the second power unit. The output end of the third power unit is connected to the third working rod 107, which moves back and forth along the length of the second feeding trough 106 under the drive of the third power unit. Figure 1 As shown, a lifting screw 6 and a pitching cylinder 7 are provided on the mounting platform 3. The output end of the lifting screw 6 is hinged to the bottom of the mounting base 101, and the output end of the pitching cylinder 7 is hinged to the bottom of the mounting base 101. The provision of the lifting screw 6 facilitates adjustment of the lifting height of the eye-blocking device 1, and the provision of the pitching cylinder 7 facilitates adjustment of the pitch angle of the eye-blocking device 1, thereby facilitating adjustment of the eye-blocking position of the first working rod 103.

[0030] When the eye plugging machine of this embodiment is used, the entire machine is moved to the side of the ore furnace via the crawler chassis. The height of the entire machine is adjusted via the support device 5. The rotation angle of the eye plugging device 1 is adjusted via the slewing support 4. The height of the eye plugging device 1 is adjusted via the lifting screw 6. The pitch angle of the eye plugging device 1 is adjusted via the pitching cylinder 7, so that the center line of the first working rod 103 points to the furnace eye and the furnace core. The plugging material is placed in the second feed trough 106. The third power unit is activated to drive the third working rod 107 to push the plugging material in the second feed trough 106 into the first feed trough 104. The second power unit is activated to drive the second working rod 105 to push the plugging material in the first feed trough 104 into the furnace eye chute. The plugging material slides down the furnace eye chute. Finally, the first power unit drives the slide bar 102 to slide along the mounting seat 101. The slide bar 102 drives the first working rod 103 to move toward the furnace eye and pokes the plugging material sliding down the furnace eye chute into the furnace eye, thereby completing the eye plugging operation. After the plugging operation is completed, the first working rod 103 is retracted and the entire machine is moved to another site via the crawler chassis 2 .

[0031] The eye-plugging machine of this embodiment, with its crawler chassis, enables free movement and relocation of the entire machine, resolving the issues of lack of space on the discharge platform of an industrial silicon ore-fired arc furnace to add a new curved track-type eye-plugging machine and the high time and financial costs of adding an additional eye-plugging machine. This embodiment of the eye-plugging machine mechanizes the eye-plugging work of an industrial silicon ore-fired arc furnace, effectively resolving the issue of the high number of operators involved in the eye-plugging process. It also significantly reduces the labor intensity and operational risks of the eye-plugging personnel at the furnace, thereby improving the efficiency of the eye-plugging operation.
