Description

Technical Field

[0001] This utility model relates to the technical field of ventilation and cooling devices, specifically a non-contact engine high-temperature exhaust suction device. Background Technology

[0002] In the field of engine testing, test benches are mostly located indoors. The high temperatures and highly polluting exhaust gases generated during engine testing are extremely harmful, not only damaging the internal environment of the plant and threatening human health, but also lingering persistently. Currently, exhaust gases are mainly discharged through pre-installed pipelines, but this method uses a rigid connection, requiring the engine and pipelines to be used together. When replacing the engine, the pipeline facilities must be replaced simultaneously, and the pipeline layout is complex, making maintenance and replacement time-consuming and labor-intensive.

[0003] Meanwhile, directly releasing untreated exhaust gas into the atmosphere will seriously damage the environment. With the continuous emergence of new engine models, higher requirements are placed on the adaptability, convenience and environmental protection of exhaust devices. Existing exhaust methods can no longer meet these needs. Therefore, we propose a non-contact engine high-temperature exhaust suction device. Utility Model Content

[0034] Structural Description:

[0035] Support and fixing base plate 1: The basic support component of the entire device. Its top surface is fixedly connected with filter pipe support platform 15 and exhaust support platform 16, which are distributed at equal intervals. The filter pipe support platform 15 is used to stably support the filter pipe 8 and ensure that the position of the filter pipe 8 is fixed. The exhaust support platform 16 provides an installation base for the exhaust component, ensuring the stability of the exhaust component when it is working, thereby maintaining the stability of the entire device.

[0036] Filter pipe 8: It is firmly fixed to the top surface of the support base plate 1 by the filter pipe support platform 15. The top surface of the filter pipe has equidistantly distributed top sliding holes 18, which cooperate with the sliding support plate 12 in the filter material collection assembly, so that the sliding support plate 12 can slide in the top sliding holes 18. The bottom has equidistantly distributed bottom sliding grooves 20 for placing the internal exhaust gas filter material collection box 7, which facilitates the collection of impurities generated by filtration. The fixed sliding groove 21 opened on the bottom side is concentrically aligned with the limiting hole 14 on one side of the internal exhaust gas filter material collection box 7. The position of the internal exhaust gas filter material collection box 7 is fixed by inserting the fixed sliding rod 6. The air guide installation hole 19 opened on the side is used to install the exhaust pipe 9, so that the exhaust assembly can be connected to the filter pipe 8 to realize the suction of exhaust gas.

[0037] Side heat dissipation plate 4: It is evenly distributed and fixedly connected to the outside of the guide heat dissipation square pipe 5. Its large surface area can increase the heat dissipation area, accelerate heat dissipation, effectively reduce the exhaust gas temperature, and reduce the impact of high temperature exhaust gas on the surrounding environment.

[0038] The square heat dissipation pipe 5 is fixed on the top surface of the supporting base plate 1. It is the channel for exhaust gas transmission, and its pipe wall can conduct the heat of the exhaust gas to the side heat dissipation plate 4 to assist in heat dissipation.

[0039] Adapter guide pipe 13: One end is connected to the front of the guide heat dissipation square pipe 5, and the other end is connected to the filter pipe 8, which serves as a transition connection, guiding the exhaust gas smoothly from the guide heat dissipation square pipe 5 into the filter pipe 8, reducing airflow resistance and ensuring the high efficiency of exhaust.

[0040] Filter pipe 8: As a carrier of the filter assembly, it provides installation space for the internal filter plate 17 and is also the place for exhaust gas filtration, guiding the exhaust gas through the internal filter plate 17 for filtration.

[0041] Internal filter plate 17: It is fixed at equal intervals on the inside of the filter pipe 8. Its special structure and material can effectively intercept solid particles and harmful substances in the exhaust gas, purify and filter the exhaust gas, and reduce pollutant emissions.

[0042] Fixed slide bar 6: Inserted into the limiting hole 14 on one side of the internal exhaust gas filter collection box 7 and the fixed slide groove 21 on the bottom side of the filter pipe 8, it plays the role of positioning and fixing the internal exhaust gas filter collection box 7, ensuring its stability during operation, and preventing shaking or displacement from affecting the impurity collection effect.

[0043] Internal exhaust gas filter collection box 7: Located in the bottom sliding groove 20, it can slide along the bottom sliding groove 20 and is used to collect impurities generated during the process of filtering exhaust gas by the filter assembly. The limiting hole 14 on one side cooperates with the fixed slide rod 6 to achieve precise positioning.

[0044] Top support spring 11: It is fixed at equal intervals on the top surface of the filter pipe 8, and its top surface is fixedly connected to the sliding support plate 12. Under normal working conditions, the top support spring 11 is in a compressed or extended state, providing upward elastic force to the sliding support plate 12. At the same time, it plays a buffering and auxiliary role when the internal exhaust gas filter collection box 7 is installed and disassembled.

[0045] Sliding support plate 12: connected to the top support spring 11 and slides within the top sliding hole 18. When it is necessary to remove the internal exhaust gas filter collection box 7, lift the sliding support plate 12 upward to overcome the elastic force of the top support spring 11 and drive the internal exhaust gas filter collection box 7 out of the bottom sliding groove 20 for easy cleaning. During installation, lower the sliding support plate 12, and under the action of the top support spring 11, make the internal exhaust gas filter collection box 7 fall accurately into the bottom sliding groove 20 and be positioned.

[0046] The exhaust pipe 9 is fixed at one end to the top of the exhaust support platform 16 and at the other end to the air guide mounting hole 19 on the side of the filter pipe 8, forming an exhaust gas suction channel. It introduces the exhaust gas discharged from the exhaust gas discharge pipe 3 of the engine 2 into the filter pipe 8. Its pipe diameter, material and connection method ensure the sealing and stability of the exhaust gas transmission, and reduce leakage and resistance.

[0047] Exhaust fan 10: It is fixedly installed inside the exhaust pipe 9. When it is powered on, it generates a strong suction force and is the power source for the entire device to achieve exhaust gas extraction. Its design parameters such as speed, blade shape and angle determine the magnitude of the suction force and the extraction effect, ensuring that the engine exhaust gas can enter the filter pipe 8 quickly and stably, and maintaining the high efficiency of the exhaust process.

[0048] Working Principle: When this utility model is needed, the exhaust fan 10 in the exhaust assembly is powered on and operates, generating a strong suction force in the exhaust pipe 9. Since one end of the exhaust pipe 9 is connected to the air guide mounting hole 19 on the side of the filter pipe 8, the suction force acts on the inside of the filter pipe 8. The exhaust gas generated when the engine 2 is working is discharged through the exhaust gas discharge pipe 3. The exhaust gas discharge pipe 3 is concentrically aligned with the heat dissipation guide assembly. Under the suction force of the exhaust fan 10, the exhaust gas quickly enters the heat dissipation guide square pipe 5 in the heat dissipation guide assembly, and then is smoothly transmitted to the filter pipe 8 through the connecting guide pipe 13, ensuring a stable and efficient exhaust process. During the exhaust gas transmission process, the heat dissipation guide assembly plays a heat dissipation role. The equidistantly distributed side heat dissipation plates 4 fixedly connected to the outside of the heat dissipation guide square pipe 5 greatly increase the heat dissipation area. The heat carried by the exhaust gas is transferred to the side heat dissipation plates 4 through the pipe wall of the heat dissipation guide square pipe 5, and then dissipated into the surrounding air, effectively reducing the temperature of the exhaust gas, reducing the impact of high-temperature exhaust gas on the surrounding environment, ensuring a suitable temperature in the working area, and extending the service life of the equipment. The exhaust gas will be filtered by the filter assembly. The internal filter plates 17 in the filter assembly are fixed at equal intervals inside the filter pipe 8. When the exhaust gas passes through the filter pipe 8, the internal filter plates 17 can intercept solid particles and harmful substances in the exhaust gas, purify the exhaust gas, and reduce pollutant emissions. The impurities produced by filtration will gradually settle at the bottom of the filter pipe 8 under the action of airflow. The filter collection assembly is responsible for collecting these impurities. The top support spring 11 fixedly connected to the top surface of the filter pipe 8 supports the sliding support plate 12. The sliding support plate 12 can be placed on the top surface. The internal exhaust gas filter collection box 7 slides within the sliding hole 18 and is located within the bottom sliding groove 20. The limiting hole 14 on one side of the box is concentrically aligned with the fixed sliding groove 21 on the bottom side of the filter pipe 8. The box is positioned by inserting the fixed sliding rod 6 into the limiting hole 14 and the fixed sliding groove 21. When the filter needs to be cleaned, simply pull out the fixed sliding rod 6 and lift the sliding support plate 12 upwards to overcome the elastic force of the top support spring 11, and the internal exhaust gas filter collection box 7 can be pulled out from the bottom sliding groove 20 for cleaning, thus achieving convenient collection and processing of the filter.
