Description

Technical Field

[0001] This utility model relates to the field of premixed fan control technology, specifically a gas premixed fan device. Background Technology

[0002] In modern industrial and civil applications, premixed gas fans are widely used as key equipment in various combustion systems to premix gas and air to improve combustion efficiency and stability. However, with the deepening of applications and the advancement of technology, traditional premixed gas fans have gradually revealed a series of problems in actual operation, which need to be solved.

[0003] Firstly, during the operation of a premixed gas system, the complex composition of the gas, the content of impurities, and environmental factors can easily lead to blockage of the airflow channels, which in turn causes an abnormal increase in pressure within the vent tee. This not only threatens the safe operation of the equipment but may also damage related components due to excessive pressure, resulting in unnecessary economic losses and safety hazards. Therefore, how to effectively release the blocked airflow while improving the utilization rate of the discharged airflow has become a problem that needs to be solved.

[0004] Secondly, as one of the core components of the gas premixed system, the performance and stability of the high-pressure blower are directly related to the operating efficiency of the entire system. However, during use, the airflow pressure state generated by the high-pressure blower is difficult to monitor in real time, which makes it impossible to detect and deal with potential fault risks in a timely manner. In addition, the pressure state in the pipeline components also lacks effective monitoring methods, which can easily affect the normal operation of the system due to excessively high or low pressure, and even accelerate the wear and tear of the equipment.

[0005] Finally, during long-term operation, high-pressure blowers generate a large amount of heat due to factors such as motor heating and airflow friction. If heat dissipation is poor, it will not only lead to excessively high blower temperature, reducing its service life and reliability, but may also cause a decrease in power due to overheating, affecting the combustion efficiency and stability of the entire system. Therefore, how to effectively improve the heat dissipation performance of high-pressure blowers and extend their service life is also a key technical challenge that needs to be addressed. Utility Model Content

[0006] To address the aforementioned issues, this invention proposes an improved gas premixed fan device. The aim is to optimize the structural design to achieve effective airflow release and utilization, real-time monitoring of airflow pressure, and enhanced heat dissipation performance of the high-pressure fan, thereby improving the overall operating efficiency and safety of the gas premixed system.

[0007] A gas premixed fan device includes an encapsulation housing, a driver fixedly installed inside the encapsulation housing for controlling the state of the device inside the encapsulation housing, and a high-pressure fan disposed inside the encapsulation housing, the outlet of the high-pressure fan being connected to a pipe assembly.

[0008] Furthermore, the pipeline assembly includes a pressure gauge, a detection tee, a vent tee, and a flow regulating valve; one end of the vent tee is equipped with a vent regulating ball valve, which is used to regulate the air pressure inside the pipeline assembly. When the airflow generated by the high-pressure blower passes through the vent tee, the vent regulating ball valve will be opened after the airflow pressure exceeds a predetermined value.

[0009] Furthermore, a vent pipe is installed at the other end of the vent regulating ball valve. One end of the vent pipe is aligned with the heat dissipation ring plate on the high-pressure blower. The airflow flowing out of the vent regulating ball valve will be controlled by the vent pipe to direct the airflow toward the high-pressure blower.

[0010] Furthermore, the pressure gauge is used to monitor the input air pressure of the high-pressure blower.

[0011] Furthermore, one end of the detection tee is connected to the air outlet of the high-pressure blower, one end of the detection tee is connected to the pressure gauge, and the other end of the detection tee is fixedly connected to the drain tee.

[0012] Furthermore, the other end of the drain tee is connected to a flow regulating valve, which is a device for controlling the opening or closing of the pipeline assembly channel. One end of the flow regulating valve is equipped with a servo motor, which can control the on / off state of the flow regulating valve.

[0013] Furthermore, an air flow meter is fixedly installed on the outer wall of the encapsulation housing, and the high-pressure blower is connected to the air flow meter through a pipe assembly. The air flow meter is used to detect the flow rate of the airflow flowing out of the pipe assembly.

[0014] Furthermore, a heat dissipation ring plate is provided on the outer wall of the high-pressure blower to help the high-pressure blower dissipate heat.

[0015] Furthermore, a radiator is fixedly installed at the bottom of the high-pressure blower. The radiator is fixed to the inner wall of the encapsulation housing and is used to assist the high-pressure blower in heat dissipation. The radiator is provided with multiple air ducts to allow airflow to pass through.

[0016] The advantages of this utility model compared with the prior art are: (1) This device sets a venting regulating ball valve at the venting tee pipe, so that the blocked airflow can be released. This not only prevents the pressure in the venting tee pipe from being too high, but also allows the discharged airflow to dissipate heat on the high-pressure blower through the venting pipe, thus improving the utilization rate of the discharged airflow; (2) This device sets a pressure gauge between the venting tee pipe and the high-pressure blower to monitor the pressure state of the airflow generated by the high-pressure blower, and can also detect the pressure state in the pipeline assembly, thus avoiding losses when the high-pressure blower is used; (3) This device sets a heat dissipation ring plate and a radiator on the outer wall of the high-pressure blower to dissipate heat on the high-pressure blower, thereby increasing the service life of the high-pressure blower and preventing the high-pressure blower from overheating and causing a decrease in power.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figure 1 , Figure 2As shown, a gas premixed fan device includes a housing 10. A driver 20 is fixedly installed inside the housing 10 to control the state of the device within the housing 10. A high-pressure fan 40 is installed inside the housing 10. An air flow meter 60 is fixedly installed on the outer wall of the housing 10. The high-pressure fan 40 and the air flow meter 60 are connected via a pipe assembly 50. An isolation plate 30 is provided inside the housing 10 to separate the positions of the driver 20 and the high-pressure fan 40. The isolation plate 30 also obstructs the airflow direction within the housing 10. During use, the top of the housing 10 is not covered. Figure 1 The state shown is the operating state of this device.

[0025] like Figures 1 to 5 As shown, a heat dissipation ring plate is provided on the outer wall of the high-pressure blower 40 to help the high-pressure blower 40 dissipate heat; a radiator 70 is fixedly installed at the bottom of the high-pressure blower 40, the radiator 70 is fixed on the inner wall of the encapsulation housing 10, the radiator 70 is used to assist the high-pressure blower 40 in dissipating heat, and multiple air ducts are provided in the radiator 70 to allow airflow to pass through.

[0026] like Figures 1 to 5 As shown, the outlet of the high-pressure blower 40 is connected to the pipe assembly 50. The pipe assembly 50 includes a pressure gauge 501, a detection tee 502, a drain tee 503, and a flow regulating valve 506. The pressure gauge 501 is used to monitor the input air pressure of the high-pressure blower 40.

[0027] A three-way pipe 502 is used for testing. One end of the three-way pipe 502 is connected to the air outlet of the high-pressure blower 40, and the other end of the three-way pipe 502 is connected to the pressure gauge 501. The other end of the three-way pipe 502 is fixedly connected to the drain three-way pipe 503.

[0028] A vent tee 503, which has the same structure as the detection tee 502, is provided with a vent regulating ball valve 504 at one end. The vent regulating ball valve 504 is used to regulate the air pressure within the pipe assembly 50. When the airflow generated by the high-pressure blower 40 passes through the vent tee 503, if the airflow pressure exceeds a predetermined value, the vent regulating ball valve 504 will be opened. A vent pipe 505 is installed at the other end of the vent regulating ball valve 504. One end of the vent pipe 505 is aligned with the heat dissipation ring plate on the high-pressure blower 40. The airflow from the vent regulating ball valve 504 will be controlled by the vent pipe 505 to direct the airflow towards the high-pressure blower 40, thereby achieving the effect of heat dissipation for the high-pressure blower 40. At the same time, the airflow from the vent pipe 505 will also pass through the air duct inside the radiator 70 to dissipate heat for the radiator 70. Finally, the airflow from the vent pipe 505 will flow out of the device from the top of the encapsulation housing 10.

[0029] The other end of the drain tee 503 is threadedly connected to the flow regulating valve 506. The flow regulating valve 506 is a device for controlling the opening or closing of the channel of the pipeline assembly 50. One end of the flow regulating valve 506 is equipped with a servo motor 507, which is controlled and started by the driver 20. The servo motor 507 can control the opening and closing state of the flow regulating valve 506, thereby controlling the airflow rate in the pipeline assembly 50. The other end of the flow regulating valve 506 is threadedly connected to the air flow meter 60, which is used to calculate the airflow rate.

[0030] This device is designed to supply oxygen to the gas premixing equipment to ensure thorough mixing of the gas and oxygen. Therefore, during operation, the device needs to adjust the intake pressure, flow rate, and flow volume according to the gas. In this device, the driver 20 controls the servo motor 507 and the flow regulating valve 506 based on data from the pressure gauge 501, the air flow meter 60, and external control equipment. It also controls the high-pressure blower 40.

[0031] The specific workflow involves a high-pressure blower 40 generating airflow, which then passes through a detection tee pipe 502 and a drain tee pipe 503 to a flow regulating valve 506. At this time, a servo motor 507 controls the size of the channel within the flow regulating valve 506 to control the airflow through the air flow meter 60. When the pressure of the airflow blocked at the flow regulating valve 506 exceeds a predetermined value, it will flow out through the drain regulating ball valve 504, allowing the airflow to flow from the drain pipe 5050 back to the high-pressure blower 40, assisting the pipe assembly 50 in heat dissipation. The predetermined value at the drain regulating ball valve 504 can be adjusted in advance. During this process, the pressure gauge 501 detects the airflow pressure within the tee pipe 502. Adjusting the airflow through the air flow meter 60 is primarily achieved by the servo motor 507 driving the flow regulating valve 506, which adjusts the size of the channel within the flow regulating valve 506 after startup.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
