Description

Technical Field

[0001] This utility model relates to the field of silica mud smelting, specifically a silica mud smelting apparatus. Background Technology

[0002] A silicon mud smelting device is an industrial equipment used to process silicon-containing waste or by-products generated during the processing of silicon materials. It recovers or purifies silicon through a high-temperature smelting process. The development of silicon mud smelting devices originated from the waste recycling needs of the silicon material industry. It has gone through a development process from simple smelting to high efficiency, environmental protection and intelligence. In the future, with the increasing requirements of green manufacturing and resource recycling, silicon mud smelting technology will continue to develop towards low energy consumption, high purity and intelligence.

[0003] While significant progress has been made in the development of silica mud smelting equipment, some shortcomings still exist in industrial applications. During the high-temperature processing of silica mud smelting equipment, harmful waste gases such as silica dust and volatile organic compounds are inevitably generated. However, some silica mud smelting equipment has poor sealing performance, especially at joint connections, which are prone to air leakage, leading to gas leakage during the smelting process and affecting environmental protection and safety. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, silica sludge smelting devices inevitably generate harmful waste gases such as silica dust and volatile organic compounds during high-temperature processing. However, some silica sludge smelting devices have poor sealing performance, especially at joint connections where air leakage is easy to occur, leading to gas leakage during the smelting process and affecting environmental protection and safety. This utility model proposes a silica sludge smelting device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a silicon mud smelting device, including a smelting furnace, a stirring shaft rotatably connected to the inner cavity of the smelting furnace, a feed pipe fixedly connected to one side of the smelting furnace, and a leak-proof mechanism provided on one side of the stirring shaft. The leak-proof mechanism includes a housing, the inner cavity of which is fitted onto the surface of the stirring shaft. One end of the housing is fixedly connected to one side of the smelting furnace. A sliding disc is slidably connected to the surface of the stirring shaft. An exhaust pipe is fixedly connected to one side of the smelting furnace. A waste gas treatment device is installed at one end of the exhaust pipe. A connecting pipe is fixedly connected to the surface of the housing, and one end of the connecting pipe is fixedly connected to one side of the waste gas treatment device.

[0006] Preferably, a limiting strip is fixedly connected to the inner wall of the outer shell, a limiting groove is formed on the surface of the sliding disk, and one side of the limiting strip is slidably connected to the inner wall of the limiting groove.

[0007] Preferably, a top cover is fixedly connected to one end of the outer shell, and a vent hole is provided on one side of the top cover.

[0008] Preferably, a fixing cylinder is fixedly connected to one side of the top cover, and an airbag is provided in the inner cavity of the fixing cylinder. The input end of the airbag is fixedly connected to one end of the vent.

[0009] Preferably, a pressure plate is slidably connected to the inner cavity of the fixed cylinder, a pressure sensor is provided at one end of the fixed cylinder, and a buzzer is provided on the surface of the outer shell.

[0010] Preferably, an elastic ring is fixedly connected to the surface of the sliding disk, and the surface of the elastic ring is in contact with the inner wall of the outer shell.

[0011] Preferably, a sealing ring is fixedly connected to one side of the top cover, and the sealing ring is sleeved on the surface of the stirring shaft.

[0012] The advantages of this utility model are: This invention, by setting up an anti-leakage mechanism, divides the inner cavity of the outer shell into a lower space and an upper space by a sliding disc. Under normal conditions, harmful gases can enter the waste gas treatment equipment for treatment through the exhaust pipe. When a leak occurs at the junction of the stirring shaft and the melting furnace, the gas in the melting furnace will enter the lower space inside the outer shell from below. The sliding disc is relatively light, and the air pressure in the lower space increases. In order to balance the air pressure, the lower space needs to be expanded, thereby pushing the sliding disc upward. When the sliding disc moves upward to the connecting pipe, the harmful gases in the lower space can enter the waste gas treatment equipment for treatment through the connecting pipe, thus achieving the effect of preventing leakage. This solves the problem that harmful waste gases such as silica dust and volatile organic compounds are inevitably generated during the high-temperature treatment of silica mud melting devices. However, some silica mud melting devices have poor sealing performance, especially at the joints, which are prone to leakage, leading to gas leakage during the melting process and affecting environmental protection and safety.

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a silica mud smelting apparatus. (Refer to...) Figures 1 to 3 A silica mud smelting device includes a smelting furnace 1, an agitator 2 rotatably connected to the inner cavity of the smelting furnace 1, a feed pipe 3 fixedly connected to one side of the smelting furnace 1, and an anti-leakage mechanism 4 provided on one side of the agitator 2. The leak-proof mechanism 4 includes a housing 401, the inner cavity of which is fitted onto the surface of the stirring shaft 2. One end of the housing 401 is fixedly connected to one side of the smelting furnace 1. A sliding disc 402 is slidably connected to the surface of the stirring shaft 2. An exhaust pipe 403 is fixedly connected to one side of the smelting furnace 1. A waste gas treatment device 405 is installed at one end of the exhaust pipe 403. A connecting pipe 404 is fixedly connected to the surface of the housing 401. One end of the connecting pipe 404 is fixedly connected to one side of the waste gas treatment device 405. By setting the leak-proof mechanism 4, the sliding disc 402 divides the inner cavity of the housing 401 into a lower space and an upper space. Under normal conditions, harmful gases can enter the waste gas treatment device 405 through the exhaust pipe 403 for treatment. When gas leakage occurs at the junction of the stirring shaft 2 and the smelting furnace 1, the gas inside the smelting furnace 1 will enter the lower space inside the outer shell 401 from below. Since the sliding plate 402 is relatively light, the gas pressure in the lower space increases. In order to balance the gas pressure, the lower space needs to be expanded, thereby pushing the sliding plate 402 to move upward. When the sliding plate 402 moves upward to the connecting pipe 404, the harmful gas in the lower space can enter the waste gas treatment equipment 405 for treatment through the connecting pipe 404. The waste gas treatment equipment 405 is an existing device, model DMC-300, and its structure includes a cyclone dust collector, a spray tower, a catalytic combustion device, and an online monitoring system. The waste gas treatment equipment 405 can collect and harmlessly treat harmful gases.

[0018] Reference Figure 4 A limiting strip 5 is fixedly connected to the inner wall of the outer shell 401, and a limiting groove 6 is opened on the surface of the sliding disk 402. One side of the limiting strip 5 is slidably connected to the inner wall of the limiting groove 6. By setting the limiting strip 5 and the limiting groove 6, since one side of the limiting strip 5 is slidably connected to the inner wall of the limiting groove 6, the limiting strip 5 can limit the sliding disk 402 with the limiting groove 6, and prevent the sliding disk 402 from flipping without affecting the vertical movement of the sliding disk 402.

[0019] Reference Figure 4 One end of the outer shell 401 is fixedly connected to the top cover 7. A vent hole 8 is provided on one side of the top cover 7. By providing the vent hole 8, when leakage occurs, the sliding plate 402 moves upward, reducing the space above, and the gas in the upper space is squeezed out through the vent hole 8.

[0020] Reference Figure 5 A fixed cylinder 9 is fixedly connected to one side of the top cover 7. An airbag 10 is provided in the inner cavity of the fixed cylinder 9. The input end of the airbag 10 is fixedly connected to one end of the vent hole 8. By setting the airbag 10, the gas in the upper space enters the airbag 10 through the vent hole 8, causing the volume of the airbag 10 to expand.

[0021] Reference Figure 1 and Figure 5A pressure plate 11 is slidably connected to the inner cavity of the fixed cylinder 9. A pressure sensor 12 is provided at one end of the fixed cylinder 9. A buzzer 13 is provided on the surface of the outer shell 401. By setting the pressure plate 11, when the airbag 10 inflates to a certain volume, the airbag 10 can lift the pressure plate 11 and press the pressure plate 11 onto the sensing end of the pressure sensor 12. The pressure sensor 12 senses the pressure, which can be processed by the PLC and transmitted to make the buzzer 13 sound an alarm. The pressure sensor 12 is an existing structure, model Honeywell, and its structure includes a sensitive element, a signal processing circuit, a ceramic diaphragm, and a capacitor plate. The buzzer 13 is an existing structure and will not be described further.

[0022] Reference Figure 4 An elastic ring 14 is fixedly connected to the surface of the sliding disk 402. The surface of the elastic ring 14 is in contact with the inner wall of the outer shell 401. By setting the elastic ring 14, mechanical wear between the sliding disk 402 and the inner wall of the outer shell 401 can be prevented when the sliding disk 402 moves, thus avoiding damage and improving the life of the device.

[0023] Reference Figure 1 A sealing ring 15 is fixedly connected to one side of the top cover 7. The sealing ring 15 is sleeved on the surface of the stirring shaft 2. By setting the sealing ring 15, air leakage is prevented from occurring due to wear between the stirring shaft 2 and the top cover 7 during long-term operation.

[0024] Working principle: The sliding disc 402 divides the inner cavity of the outer shell 401 into a lower space and an upper space. Under normal conditions, harmful gases can enter the waste gas treatment equipment 405 for treatment through the exhaust pipe 403. When a leak occurs at the junction of the stirring shaft 2 and the smelting furnace 1, the gas in the smelting furnace 1 will enter the lower space inside the outer shell 401 from below. The sliding disc 402 is relatively light, and the air pressure in the lower space increases. In order to balance the air pressure, the lower space needs to be expanded, thereby pushing the sliding disc 402 upward, reducing the space of the upper space. The gas in the upper space enters the air bag 10 through the vent 8, causing the air bag 10 to expand. When the air bag 10 expands to a certain volume, the air bag 10... The pressure plate 11 can be lifted and pressed against the sensing end of the pressure sensor 12. The pressure sensor 12 senses the pressure, and the signal can be processed and transmitted through the PLC to make the buzzer 13 sound an alarm to notify the staff to deal with it as soon as possible. When the gas leakage is serious, the sliding plate 402 moves up to the connecting pipe 404. The harmful gas in the space below can enter the waste gas treatment equipment 405 for treatment through the connecting pipe 404. The waste gas treatment equipment 405 is an existing device, model DMC-300. Its structure includes a cyclone dust collector, a spray tower, a catalytic combustion device and an online monitoring system. The waste gas treatment equipment 405 can collect and harmlessly treat harmful gases.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
