It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0035] The following combination Figure 1-3 The specific embodiment of the utility model is described, which is a new type of boosting mechanism for a copper reduction furnace, comprising:

[0036] The base frame 1 is provided with a first pipeline 11 and a second pipeline 12. One end of the first pipeline 11 serves as a gas input end, connected to natural gas, so that the natural gas is used as a copper reduction medium. The second pipeline 12 serves as an output pipeline for compressed and pressurized natural gas.

[0037] The buffer assembly 2 includes an air inlet buffer 21 and an air outlet buffer 22. The air inlet buffer 21 is connected to the first pipeline 11, and the second pipeline 12 is connected to the air outlet buffer 22. The air inlet buffer 21 and the air outlet buffer 22 are used to buffer the natural gas before it enters the machine for compression and supercharging and after it is compressed and supercharged, respectively, to prevent excessive gas pressure from causing damage to the interior of the compression equipment, the second pipeline 12, and various components connected to the rear end of the output pipeline;

[0038] The compression assembly 3 includes a compression main unit 31. The two ends of the compression main unit 31 are respectively connected to the air inlet buffer 21 and the air outlet buffer 22. The compression assembly 3 compresses the gas input from the air inlet buffer 21 to change the gas pressure, actively pressurizing the natural gas, and increasing its pressure from 2 kg to about 4 kg. The pressurized gas is injected into the copper liquid through a reduction valve group (controlling safety and flow), so that the natural gas is fully in contact with the copper liquid, and the oxygen element in the copper liquid can be quickly reduced;

[0039] The cooling assembly 4 is fixedly mounted on the base frame 1 and is used to cool the gas flowing out of the output end of the second pipe 12. The cooling assembly 4 is used to reduce the temperature value of the compressed gas when it is output from the mechanism.

[0040] Please refer to Figure 1-Figure 2 As shown, the first pipe 11 is provided with:

[0041] An air intake filter (not shown) is installed at the air intake end of the first pipe 11. When the gas enters the mechanism, it filters the particulate matter mixed in the gas to prevent it from entering the mechanism and affecting the service life of the structure;

[0042] A first check valve 111 is connected to the first pipe 11 and is located between the air intake filter and the air intake buffer 21. The first check valve 111 is used to prevent backflow of gas after entering the first pipe 11. The first check valve 111 is located at the front end of the first pipe 11. The first check valve 111 is used to prevent backflow of gas after entering the first pipe 11;

[0043] A second check valve 117 is connected to the first pipe 11 and is close to the output end of the first pipe 11. The second check valve 117 is used to prevent backflow of fluid at the output end of the first pipe 11. The second check valve 117 is used to prevent backflow of gas output from the first pipe 11;

[0044] The three-way valve 112 is connected to the first pipeline 11, and its top end is connected to the input end of the air intake buffer 21. The two lateral ends of the three-way valve 112 are connected to the first pipeline 11, and its top end is connected to the air intake buffer 21. When the compression component 3 fails to work, the gas can be directly output through the first pipeline 11 to ensure the supply to the smelting.

[0045] Please refer to Figure 2 As shown, the first pipe 11 is further provided with:

[0046] The pressure regulating valve 113 is connected to the first pipeline 11 and is used to adjust the pressure of the gas in the first pipeline 11. The pressure regulating valve 113 is used to adjust the pressure value retained in the first pipeline 11. When the gas pressure value of the compressed and pressurized gas is too high due to damage to the outlet buffer 22, the high-pressure gas cannot be output through the first pipeline 11. At this time, the high-pressure gas flows back to the intake buffer 21 and the compression component 3 through the first pipeline 11, participating in secondary compression to adjust the output gas pressure value, and the pressure regulating valve 113 can adjust the pressure value of the output end of the first check valve 111.

[0047] A bypass pipe 115 is disposed around the pressure regulating valve 113 and connected to the first pipeline 11 at both ends. A bypass valve 114 is provided on the bypass pipe 115 to prevent damage to the pressure regulating valve 113 that would result in a loss of pressure regulation. The bypass valve 114 can manually adjust the air pressure output from the first pipeline 11.

[0048] The low-leakage and high-sealing valve 116 is connected to the output end of the first pipeline 11. The low-leakage and high-sealing valve 116 can control the pressure of the output gas so that the gas below the set pressure value can be output through the first pipeline 11, while the gas above the set output pressure value can flow back through the first pipeline 11 to adjust the pressure.

[0049] Please refer to Figure 2 As shown,

[0050] The pressure regulating valve 113 is an automatic regulating valve, and the pressure regulating valve 113 can be controlled by a program;

[0051] The bypass valve 114 is a manual regulating valve. The bypass valve 114 is manually regulated and serves as a backup regulating method when the pressure regulating valve 113 is damaged.

[0052] Please refer to Figure 1-Figure 3 As shown, the compression assembly 3 further includes a variable frequency motor 32, the variable frequency motor 32 is fixedly mounted on the base frame 1, and the output end of the variable frequency motor 32 is transmission-connected to the compression main unit 31;

[0053] The output end of the air intake buffer 21 is connected to the compression main unit 31, the input end of the air outlet buffer 22 is connected to the compression main unit 31, and the output end of the air outlet buffer 22 is connected to the second pipeline 12. The air intake buffer 21 is used to reduce the pressure value of the gas input into the compression main unit 31, and the air outlet buffer 22 is used to reduce the pressure value of the gas output from the compression main unit 31.

[0054] Please refer to Figure 1-Figure 2As shown, the cooling component 4 includes a cooler 41, and the input end of the cooler 41 is connected to the end of the second pipe 12 away from the air outlet buffer 22 through a pipeline, and the output end of the cooler 41 is connected to the second pipe 12 through a pipeline. The temperature of the gas increases when it participates in compression and supercharging, and its temperature is higher than the required temperature of the gas output. After the compressed gas is output, it is transported to the cooler 41 through the second pipe 12 for cooling, and the cooled fluid is then output to achieve the required output gas temperature. A temperature control module (not shown) is provided in the cooler 41, and the temperature control module is used to detect the temperature in the cooler 41 and control the temperature value of the fluid output from the cooler 41 so that the temperature of the compressed air output does not exceed the limit value.

[0055] Please refer to Figure 2 As shown, a safety valve 42 is provided on the top of the cooler 41 , and the safety valve 42 is communicated with the interior of the cooler 41 . The safety valve 42 is used to release pressure inside the cooler 41 to avoid internal pressure buildup and damage to the equipment.

[0056] Please refer to Figure 3 As shown, the oil pump assembly 5 is fixedly installed with the base frame 1 , and the oil pump assembly 5 is used for lubricating the compression assembly 3 . The oil pump assembly 5 is used for lubricating the compression assembly 3 when it is working.

[0057] The working principle of this utility model:

[0058] The natural gas is connected to one end of the first pipeline 11. The gas input end of the first pipeline 11 is connected to an intake filter for filtering the gas. After passing through the intake filter, the gas flows through the first check valve 111. The first check valve 111 can prevent the input gas from flowing back. The gas passes through the three-way valve 112 and flows into the intake buffer 21. The intake buffer 21 buffers the inflowing gas to prevent the compression component 3 from being damaged by excessive pressure when entering the compression component 3. The gas is compressed and pressurized under the action of the variable frequency motor 32 and the compression host 31. The compressed and pressurized gas flows into the outlet buffer 22, and the pressure value of the output gas in the compression host 31 is controlled. After adjusting the buffer, the gas passes through the second pipeline 12, the input pipeline of the cooler 41 and the cooler 41 in sequence. The gas is cooled and cooled under the action of the cooler 41, and is finally output through the output pipeline of the cooler 41 and flows to the first pipeline 11. Finally, it is output from the device through the low leakage valve 116 and the second check valve 117, thereby realizing active pressurization of the gas.

[0059] Among them, when the gas outlet buffer 22 fails or the pressure value of the output gas exceeds the required pressure, the gas is restricted by the low-leakage and high-sealing valve 116, resulting in the high-pressure gas output by the cooler 41 being unable to be output from the output end of the first pipeline 11. At this time, the high-pressure gas flows back through the first pipeline 11, and the gas flows back to the gas inlet buffer 21 through the pressure regulating valve 113 or the bypass valve 114, buffering the gas pressure value, performing secondary compression and pressurization, and adjusting the output pressure value of the gas. Among them, the pressure regulating valve 113 and the bypass valve 114 can respectively control the pressure value of the gas output, and are automatically adjusted and manually adjusted respectively, which are suitable for different working conditions of the equipment;

[0060] A safety valve 42 with a pressure gauge is provided on the top of the cooler 41, which can be used to release pressure inside the cooler 41 to ensure the normal operation of various components.

[0061] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0062] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
