[0002] Industrial silicon is produced by generating high temperatures through electrodes being charged. The main equipment, the electric furnace, is generally at a voltage level of 35KV, while the auxiliary circulating water system and dust removal system use a voltage level of 10KV.

[0003] During the production process, the dust removal system and the circulating water system play a crucial role in ensuring normal production. If the dust removal system or the circulating water system fails and shuts down, the main equipment, the electric furnace, must also be shut down and production suspended. In existing industrial silicon production, if the dust removal system or the circulating water system suddenly shuts down due to equipment failure, it is necessary to manually notify the electric furnace to cut off the power, start the diesel generator to generate electricity to power low-voltage equipment such as lighting, and start the diesel circulating water pump to supply water to the furnace platform to protect the auxiliary equipment of the furnace platform from damage and prevent the accident from escalating.

[0004] The entire process of handling such equipment malfunctions is human-driven, which is characterized by delays and uncertainties. In cases where personnel are absent from their posts, the inability to respond quickly can further lead to equipment accidents. In addition, generators tend to generate excessive noise during operation, affecting the quietness of the surrounding environment.

[0005] Therefore, an interlocking device for the electrical system of an industrial silicon furnace is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figure 1 - Figure 4 An industrial silicon furnace electrical system interlocking device in this embodiment includes a 10KV control cabinet 1, a generator 2, a circulating water pump 3, and a furnace platform 4. The 10KV control cabinet 1 is equipped with a self-cutting protection circuit breaker 101 and a circulating water pump controller 102 for control support. The generator 2 is equipped with a generator controller 103 for control support. The self-cutting protection circuit breaker 101, the circulating water pump controller 102, and the generator controller 103 are electrically connected.

[0031] The generator 2 is provided with a fastening mechanism 5 for fastening and support on the outside. The generator 2 is provided with an isolation cover 6 for protection and sound insulation support on the outside. The isolation cover 6 is provided with a sound insulation cover 601, a sound absorption cover 602, and a buffer pad 603 inside.

[0032] The combination of 10KV control cabinet 1, self-cutting protection switch circuit breaker 101, circulating water pump controller 102, and generator controller 103 forms an automatic protection control system, which provides automatic control for generator 2, circulating water pump 3, and furnace 4. This enables automatic monitoring and alarm in 10KV control cabinet 1, automatic activation of self-cutting protection switch circuit breaker 101, and sending a start signal to generator controller 103. Generator 2 then automatically starts and supplies power to lighting, and sends a start signal to circulating water pump controller 102, which then starts circulating water pump 3 to supply water to furnace 4.

[0033] Furthermore, the 10KV control cabinet 1 is equipped with a voltage detection module and a signal processing module. The voltage monitoring module is electrically connected to the signal processing module. The voltage monitoring module is located in the 10KV control cabinet 1 and is used to acquire regional voltage information and convert it into an electrical signal for transmission to the processor module. The processor module is used to identify the electrical signal and acquire instantaneous voltage information. The control system is a PC-based DCS control system. Since this control start-up method is existing technology, it is not described in detail in this example.

[0034] The generator 2 is positioned by using a fastening mechanism 5 to prevent it from shaking and vibrating. The noise generated by the generator 2 during operation is isolated and absorbed by the combination of the soundproof cover 601, the sound-absorbing cover 602, and the buffer pad 603, preventing it from generating excessive noise and ensuring the stable operation of the generator 2.

[0035] The fastening mechanism 5 consists of a fastening arm 501 and an auxiliary arm 502 that are symmetrically arranged. One end of the fastening arm 501 is fixedly connected to a connector strip 503, which is inserted into the horizontal part of the auxiliary arm 502.

[0036] Both the plug-in strip 503 and the auxiliary arm 502 have through-hole fastening screw holes 504, and the spacing between two adjacent fastening screw holes 504 on the plug-in strip 503 and the auxiliary arm 502 is the same.

[0037] A rotating column 505 is installed on the side of the auxiliary arm 502. The upper half of the rotating column 505 is rotatably equipped with a rotating arm 506 and a telescopic arm 507. A fastening bolt 509 is inserted through the outer half of the rotating arm 506, and a positioning bolt 508 is inserted through the outer half of the telescopic arm 507. Both the fastening bolt 509 and the positioning bolt 508 are inserted into the fastening screw hole 504.

[0038] By rotating the fastening arm 501 and the auxiliary arm 502 inside the isolation cover 6, after the generator 2 is secured, the fastening arm 501 is rotated so that the connector strip 503 is inserted into the auxiliary arm 502. By pulling the telescopic arm 507, the positioning bolt 508 is first inserted into the fastening screw hole 504 on the connector strip 503. Then, the positioning bolt 508 is rotated so that the connector strip 503 moves into the auxiliary arm 502. After the fastening screw holes 504 on both sides are aligned and connected, the fastening bolt 509 is rotated so that it is threadedly connected to the inner wall of the fastening screw hole 504, so that the connector strip 503 and the auxiliary arm 502 are in a fastened connection state, providing a fastening effect for the generator 2 located in the middle.

[0039] Based on the sliding extension and retraction of the telescopic arm 507 itself, the telescopic arm 507 has the effect of length adjustment, ensuring reliable and convenient angle connection when rotating.

[0040] The soundproof cover 601 is installed on the inner wall of the isolation cover 6, the sound-absorbing cover 602 is installed on the inner wall of the soundproof cover 601, the buffer pad 603 is installed on the lower end face of the inner wall of the isolation cover 6, and the fastening mechanism 5 is located between the sound-absorbing cover 602 and the buffer pad 603.

[0041] The combination of buffer pad 603, sound-absorbing cover 602, sound insulation cover 601 and isolation cover 6 forms a sound insulation space, which absorbs and cancels the sound generated outside the generator 2, reducing the noise impact generated during its operation.

[0042] Example 1:

[0043] The sound-absorbing cover 602 has a number of flow holes 6021, and the flow holes 6021 are evenly distributed.

[0044] The flow hole 6021 is a tapered through hole that gradually increases in size from the inside to the outside;

[0045] By using a combination of multiple flow holes 6021 inside the sound-absorbing cover 602, the noise generated by the generator 2 flows in through the small holes and out through the large holes, increasing the contact area between the noise and the sound-absorbing cover 602. Furthermore, the sound is reflected and canceled out multiple times during transmission due to the rebound of the arc-shaped inclined surface inside the flow hole 6021, thus reducing the noise intensity.

[0046] Example 2:

[0047] The sound-absorbing cover 602 has a number of flow holes 6021, and the flow holes 6021 are evenly distributed.

[0048] The flow hole 6021 is a tapered through hole that gradually decreases in size from the inside to the outside;

[0049] By using a combination of multiple flow holes 6021 inside the sound-absorbing cover 602, the noise generated by the generator 2 flows in through the large holes and out through the small holes, increasing the contact area between the noise and the sound-absorbing cover 602. Furthermore, the sound is reflected off the curved slope inside the flow holes 6021, causing the sound to be canceled out by multiple reflections during transmission, thus reducing the noise intensity. Also, since the two sides of the isolation cover 6 are not sealed, it is convenient to adjust and repair the generator 2.

[0050] Example 3:

[0051] The sound-absorbing cover 602 has a number of flow holes 6021, and the flow holes 6021 are evenly distributed.

[0052] The flow hole 6021 is a uniform cylindrical through hole;

[0053] By using a combination of multiple flow holes 6021 inside the sound-absorbing cover 602, the noise generated by the generator 2 enters its interior at different angles, and under the reflection support of its internal arc-shaped surface, it produces a canceling effect during sound transmission, reducing the noise intensity.

[0054] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0055] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
