Description

Technical Field

[0001] This utility model relates to the field of fan boosting technology, specifically a fan boosting and regulating device. Background Technology

[0002] To ensure the stable and efficient operation of gas burners and generate sufficient temperatures to meet various industrial or heating demands, the gas pressurization and delivery system plays a crucial role. This system must provide a continuous and stable gas flow rate to the burner via a compressor, as fluctuations in gas flow rate directly affect combustion efficiency and temperature output. Currently, regulating valves are commonly used to adjust the gas flow rate. These valves typically have a minimum adjustment value; if the flow rate falls below this value, the compressor will malfunction, leading to insufficient gas supply. This, in turn, causes burner failure, resulting in decreased combustion efficiency and an inability to meet required heating temperatures. Consequently, this impacts the continuity of industrial production and product quality.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0019] Please see Figure 1-3 In order to solve the problem that if the flow rate of gas is lower than the minimum adjustment value of the regulating valve 4, the compressor 1 will fail, resulting in insufficient gas supply, burner failure, reduced combustion efficiency, inability to meet the required heating temperature, and thus affecting the continuity of industrial production and product quality, this technical solution is designed. The detailed technical solution is as follows.

[0020] A fan booster regulating device includes a booster 1, a gas flow rate sensor 2 installed at the air inlet end of the booster 1, and an regulating structure installed at one end of the gas flow rate sensor 2.

[0021] It should be noted that a controller can be set in the entire gas transmission system. The structure and working principle of the controller can be referred to the 1625140402 main controller produced by Huaxin Hangyuan (Beijing) Technology Co., Ltd. Since it is existing technology, it will not be described in detail here. The compressor 1 is connected to the gas combustion equipment, the regulating structure is used to transport gas, and the gas flow rate sensor 2 is used to detect the gas flow rate at the gas inlet of the compressor 1.

[0022] Specifically, the regulating structure includes a first connecting pipe 3, a regulating valve 4 installed on the first connecting pipe 3, a second connecting pipe 5 installed at one end of the regulating valve 4, and a reinforcing part installed in parallel between the first connecting pipe 3 and the second connecting pipe 5 and the regulating valve 4.

[0023] It should be noted that the gas flow rate sensor 2 is set with a standard value and a minimum limit value. If the minimum limit value is less than the standard value, the booster is closed under normal conditions. The gas flows through the second connecting pipe 5, the regulating valve 4, the first connecting pipe 3, the gas flow rate sensor 2, and the second connecting pipe 5 into the compressor 1. The compressor 1 pressurizes the gas and supplies gas to the gas combustion equipment. The gas flow rate sensor 2 detects the gas flow rate. If the flow rate is less than the standard value but greater than the minimum limit value, and is still within the range that the regulating valve 4 can adjust, the controller receives the signal sent by the gas flow rate sensor 2, and the opening of the regulating valve 4 is automatically adjusted, that is, the opening of the regulating valve 4 is increased so that the gas flow rate through the second connecting pipe 5 reaches the standard value. If the flow rate is greater than the standard value, the controller receives the signal sent by the gas flow rate sensor 2, and the opening of the regulating valve 4 is automatically adjusted, that is, the opening of the regulating valve 4 is decreased so that the gas flow rate through the second connecting pipe 5 reaches the standard value, ensuring that the compressor 1 works normally.

[0024] Specifically, the reinforcement includes a connecting pipe 6, a support rod 7 is installed on the inner wall of the connecting pipe 6, a fixed sleeve 8 is installed on the support rod 7, a rotating rod 10 is movably inserted into the fixed sleeve 8 through a bearing 9, a fan blade 11 is fitted at one end of the rotating rod 10, a driven bevel gear 12 is fitted at the other end of the rotating rod 10, and a drive assembly is meshed on the driven bevel gear 12.

[0025] It should be noted that the gas flow rate sensor 2 detects the gas flow rate. If the flow rate is less than the minimum limit, it is not within the range that the regulating valve 4 can adjust. The controller receives the signal sent by the gas flow rate sensor 2 and controls the enhancement unit to work, that is, the drive assembly works. Under the connection of the driven bevel gear 12, the rotating rod 10 rotates on the fixed sleeve 8 through the bearing 9, and the fan blade 11 rotates accordingly, which accelerates and pressurizes the gas flow through the connecting pipe 6 until the gas flow rate sensor 2 detects that the gas flow rate has reached the standard value. This ensures that the pressurizer 1 works normally, avoids the pressurizer 1 from stopping, ensures sufficient gas supply, ensures that the burner works normally, ensures combustion efficiency, reaches the required temperature, and ensures the continuity of industrial production and product quality.

[0026] Specifically, the drive assembly includes a longitudinal rod 13, which is movably inserted into the connecting pipe 6. One end of the longitudinal rod 13 located inside the connecting pipe 6 is fitted with a drive bevel gear 14, which meshes with the driven bevel gear 12. A motor 15 is installed at the other end of the longitudinal rod 13 located outside the connecting pipe 6.

[0027] It should be noted that the operation of motor 15 causes the longitudinal rod 13 to rotate, and the active bevel gear 14 drives the driven bevel gear 12 to rotate. When the speed of motor 15 increases, the speed of fan blade 11 will also increase accordingly, thereby generating stronger wind force, which increases the gas flow velocity and pressure of the gas flowing through connecting pipe 6.

[0028] Preferably, a switch valve 16 is installed between the regulating valve 4, the connecting pipe 6 and the first connecting pipe 3. When the reinforcing part is not working, the switch valve 16 on the reinforcing part side is closed and the switch valve 16 on the regulating valve 4 side is open. When the reinforcing part is working, the switch valve 16 on the reinforcing part side is open and the switch valve 16 on the regulating valve 4 side is closed.

[0029] Preferably, a first frequency converter 17 is connected to the motor 15. When the gas flow rate is lower than the standard value, the controller sends a signal to the first frequency converter 17, requesting it to increase the speed of the motor 15, thereby driving the fan blades 11 to rotate faster and generate stronger wind to accelerate the gas flow. Conversely, when the gas flow rate is too high, the first frequency converter 17 will reduce the speed of the motor 15 to reduce the speed of the fan blades 11 and the wind force.

[0030] Preferably, and further, the compressor 1 is connected to a second frequency converter 18. When the gas flow rate needs to be adjusted, the controller sends a signal to the second frequency converter 18, requesting it to increase or decrease the speed of the compressor 1.

[0031] As a preferred and further option, a retaining bracket 19 is installed between the motor 15 and the connecting pipe 6 for fixing the motor 15.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
