Description

Technical Field

[0001] This application relates to the field of submerged arc furnace technology, and in particular to a submerged arc furnace baffle mechanism and an industrial silicon tapping machine. Background Technology

[0002] Submerged arc furnaces are mainly used for reducing and smelting raw materials such as ores. Currently, submerged arc furnaces, especially rotary submerged arc furnaces, often use shield trolleys during the tapping process. This shield trolleys protect the personal safety of operators when manually opening, pulling, and plugging the furnace openings, preventing them from being burned by the splashed hot liquid. In addition, during the tapping process when no one is operating the furnace, the shield can be used to block the furnace opening and the operating platform, preventing sudden flames or material collapses from causing injury to personnel and equipment on the operating platform.

[0003] Existing shielding trolleys are often non-powered, with a shielding door attached to the bottom. When needed, the operator must manually push it to the furnace opening. This operation firstly increases the probability of the operator being exposed to a high-temperature and high-dust environment, and also increases the operator's labor intensity. In addition, because the shielding trolley needs to be moved frequently, the operator may become complacent, resulting in the shielding door not being moved to the designated position as required, thus causing unpredictable accidents. Summary of the Invention

[0004] This application proposes a baffle mechanism for a submerged arc furnace and an industrial silicon tapping machine, which has the advantages of reducing the labor intensity of operators and improving safety, and is used to solve the problem of unnecessary injury and loss to personnel and equipment caused by the baffle trolley not being in the furnace mouth area in time.

[0005] To achieve the above objectives, this application adopts the following technical solution: a baffle mechanism for a submerged arc furnace, comprising a frame and a track: the frame is disposed below the track;

[0006] The speed reducer is fixed to the middle position on the side of the frame;

[0007] The drive wheel is located on the left side of the reducer, and the drive wheel is fixedly connected to the output end of the reducer;

[0008] A drive motor is fixed to the upper side of the frame and located behind the reducer. The output end of the drive motor is fixedly connected to the input end of the reducer.

[0009] The mounting base is fixed on the upper side of the frame and located on the side of the reducer facing away from the drive wheel. There are two mounting bases, and the sides of the two mounting bases facing away from the reducer are fixedly connected to the support wheel through connecting rods.

[0010] The vehicle frame is suspended from the track via a drive wheel and a support wheel;

[0011] The encoder positioning device is fixed on one side of the frame corresponding to the drive wheel and is used to sense the specific position of the frame on the track.

[0012] A screen door is suspended from the middle of the lower side of the vehicle frame via a pin, which is used to isolate the furnace hole of the submerged arc furnace from the working platform.

[0013] Furthermore, guide wheels are fixedly installed on one side of the frame corresponding to the two mounting seats. There are four guide wheels in total. The four guide wheels are grouped in pairs and the grouped guide wheels are locked on both sides of the track on one side to guide the frame.

[0014] Furthermore, a level sensor is fixedly installed on the upper side of the reducer.

[0015] Furthermore, a rotating motor is fixedly installed on the upper side of the frame, located between the two mounting seats, and the level sensor is electrically connected to the rotating motor.

[0022] Furthermore, the lifting rod is made of an elastic material and is located on the side facing the transmission gear and below the tooth groove.

[0023] An industrial silicon tapping machine includes a traveling mechanism, an opening mechanism, and a baffle mechanism for a submerged arc furnace as described above. The traveling mechanism is located on the lower side of the track, and the opening mechanism is installed on the upper side of the traveling mechanism.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] Example 1

[0035] Please see Figure 1 and Figure 2 A shielding mechanism for a submerged arc furnace includes a frame 1 positioned below a track 2. A reducer 3 is fixedly mounted on the middle of the upper side of the frame 1. A drive wheel 4 is located on the left side of the reducer 3 and is fixedly connected to the output end of the reducer 3. A drive motor 5 is fixedly mounted on the upper side of the frame 1, located behind the reducer 3, and its output end is fixedly connected to the input end of the reducer 3. Two mounting seats 6 are fixedly mounted on the upper side of the frame 1, located on the side of the reducer 3 facing away from the drive wheel 4. Both mounting seats 6 are fixedly connected to support wheels 7 via connecting rods on their sides facing away from the reducer 3. The frame 1 is suspended on the track 2 via the drive wheel 4 and support wheels 7. An encoder positioning device 8 is fixedly mounted on the side of the frame 1 corresponding to the drive wheel 4 to sense the specific position of the frame 1 on the track 2. A shielding door 9 is suspended from the middle of the lower side of the frame 1 via a pin to isolate the furnace eye of the submerged arc furnace from the working platform.

[0036] In use, the drive motor 5 is controlled by the remote operation platform, which, in conjunction with the reducer 3, drives the drive wheel 4 to rotate. This causes the drive wheel 4 to generate friction with the track 2, thus moving the frame 1. Simultaneously, the encoder positioning device 8 detects the movement distance of the frame 1, thereby determining the position information of the frame 1 and the barrier door 9. This information is then transmitted to the remote operation platform, which can then control the start and stop of the drive motor 5 based on the transmitted position information. Through these actions, the automated movement and positioning of the barrier door 9 are achieved, solving the problem of unnecessary injury and loss to personnel and equipment caused by the barrier door 9 failing to isolate the furnace hole of the submerged arc furnace from the working platform in a timely manner.

[0037] Please see Figure 1 and Figure 2 The frame 1 is fixedly installed with guide wheels 10 on one side of each of the two mounting seats 6. There are four guide wheels 10 in total. The four guide wheels 10 are grouped in pairs and the grouped guide wheels 10 are locked on both sides of the track 2 on one side to guide the frame 1.

[0038] During the movement of the frame 1, the guide wheel 10 guides the frame 1 to prevent it from deviating from the track 2 and avoid unnecessary damage and loss.

[0039] An industrial silicon tapping machine includes a baffle mechanism for a submerged arc furnace as provided in this application embodiment. A traveling mechanism is provided on the lower side of the track 2, and an opening mechanism is fixedly installed on the upper side of the traveling mechanism. The baffle mechanism and the industrial silicon tapping machine are on the same moving path. In use, the industrial silicon tapping machine first opens the furnace eye of the submerged arc furnace (by burning through the furnace eye with a burner or by knocking open the furnace eye with a metal rod). Then, the traveling mechanism drives the opening mechanism away from the furnace eye and moves the baffle mechanism toward the furnace eye. The baffle mechanism and the traveling mechanism are linked and controlled to realize the automated control of this application embodiment.

[0040] Example 2

[0041] Please see Figures 1-4 This embodiment is a further improvement on Embodiment 1. The improvement is as follows: a horizontal sensor 11 is fixedly installed on the upper side of the reducer 3; a rotary motor 12 is fixedly installed on the upper side of the frame 1, located between the two mounting seats 6; the horizontal sensor 11 and the rotary motor 12 are electrically connected; a drive gear 13 is fixedly installed on the shaft of the rotary motor 12; a driven gear 14 is meshed above the drive gear 13; a fixing rod 15 is fixedly installed at the center of the driven gear 14; both ends of the fixing rod 15 extend into the corresponding mounting seats 6; a transmission gear 16 is rotatably installed inside the mounting seat 6; and the transmission gear 16 and the fixing rod 15 are connected. The ends are fixedly connected, the connecting rod is located below the transmission gear 16, the connecting rod is slidably engaged with the inside of the mounting base 6, and a lifting rod 17 is provided inside the mounting base 6 and above the connecting rod. The lower end of the lifting rod 17 is welded to the connecting rod. The side of the lifting rod 17 facing the transmission gear 16 has longitudinally equidistant toothed grooves, and the transmission gear 16 is meshed with the toothed grooves (the horizontal sensor 11 has a predetermined value. When the frame 1 tilts towards the drive wheel 4, the horizontal sensor 11 outputs a rotation signal to the rotating motor 12; when the frame 1 is balanced, the horizontal sensor 11 outputs a stop rotation signal to the rotating motor 12).

[0042] Since the frame 1 is driven by the friction between the rotating drive wheel 4 and the track 2, the wear of the drive wheel 4 is greater than that of the support wheel 7. As a result, during long-term use of this device, the frame 1 will tilt towards the drive wheel 4. At this time, the horizontal sensor 11 outputs a rotation signal to the rotating motor 12, causing the rotating motor 12 to drive the driven gear 14, the fixed rod 15 and the transmission gear 16 to rotate slowly through the power gear 13. Since the transmission gear 16 engages with the groove of the lifting rod 17, the lifting rod 17 moves upward and drives the connecting rod and the support wheel 7 to move upward synchronously, causing the side of the frame 1 corresponding to the support wheel 7 to tilt downward. Through this action, the frame 1 is leveled back. At this time, the horizontal sensor 11 outputs a stop rotation signal to the rotating motor 12, causing the above structure to stop operating. Through the above action, the probability of increased wear between the guide wheel 10 and the track 2 when the frame 1 tilts towards the drive wheel 4 is reduced, making it less likely for the distance between the guide wheel 10 and the track 2 to increase, and thus making the guiding function of the guide wheel 10 less affected.

[0043] Please see Figures 1-4 An alarm 18 is fixedly installed on the upper side of the reducer 3. The alarm 18 is electrically connected to the level sensor 11. (When the frame 1 tilts towards the drive wheel 4 for a long time (the time can be set), the level sensor 11 outputs a stop rotation signal to the rotating motor 12 and outputs a running signal to the alarm 18).

[0044] When the frame 1 tilts towards the drive wheel 4 for an extended period of time (when the lifting rod 17 moves to its limit position and the drive wheel 4 continues to wear, the transmission gear 16 driven by the rotating motor 12 cannot drive the lifting rod 17 to continue moving upward, thus causing the frame 1 to tilt towards the drive wheel 4 continuously), the level sensor 11 outputs a stop signal to the rotating motor 12 and an operation signal to the alarm 18, causing the alarm 18 to sound an alarm, thereby prompting the operator to react, stop the above mechanism, and replace the drive wheel 4.

[0045] The lifting rod 17 faces the side of the transmission gear 16 and is located below the tooth groove, and is made of elastic material (not shown in the figure).

[0046] When the transmission gear 16 driven by the rotating motor 12 is unable to drive the lifting rod 17 to continue moving upward, the transmission gear 16 will contact the elastic material at the bottom of the lifting rod 17, and thus continuously slip at that position. Through the above action, the rotation motor 12, the drive gear 13, the driven gear 14, the fixed rod 15 and the transmission gear 16 will not be subjected to hard force due to the lifting rod 17 being unable to continue moving upward, thereby avoiding damage to the above structure.
