Abstract
Description
Technical fields:
[0001] This utility model relates to the field of ventilation technology, and more specifically to a high-speed ventilation device. Background technology:
[0002] In existing high-temperature carbonization furnaces or some heat treatment furnaces, air needs to be blown inside to cool them down as needed. Therefore, a corresponding ventilation device is required. The current method is to directly install a fan around the furnace body, and connect the fan's outlet to the carbonization furnace or heat treatment furnace through a connecting pipe for ventilation. However, existing fans generally do not have corresponding controllers and cannot achieve automatic switching on and off according to ventilation needs. Therefore, a box is needed to install the fan and control host in the box, and the control host controls the operation and shutdown of the fan. However, after the fan motor runs for a long time, its temperature will rise, which will cause the temperature inside the box to rise. Therefore, the control host installed in the same box will be affected by the high temperature, reducing its service life and making it easy to be damaged due to high temperature.
[0003] At the same time, existing ventilators lack soundproofing components and other structures, causing the noise they generate during operation to be transmitted outwards first, resulting in excessive ambient noise and serious noise pollution. Utility model content:
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-speed ventilation device that separates the control unit and the fan by a partition plate, reducing the impact of the fan's operating temperature on the control unit and ensuring the operating life of the control unit.

Of course, other fans can also be used, but it is necessary to ensure that the bottom of the drive motor of the fan 30 has an air inlet and the side wall of the housing has a side air outlet. In this embodiment, the bottom end of the housing of the bottom drive motor 31 of the fan 30 is fixed with a lower cover. A ventilation opening is formed in the middle of the bottom plate of the lower cover.

[0044] Furthermore, a control host is fixed on the side wall of the partition plate 11 at the control cavity 101, and multiple cooling fans 17 are fixed on one side wall of the control cavity 101. The air outlets of all cooling fans 17 face the ventilation holes of the corresponding side plate of the control cavity 101.
[0045] A liquid crystal display controller 106 is fixed on the inner wall of one side panel of the housing 10 at the control cavity 101.

[0046] Its control host, LCD display controller 106 and other components are all conventional components, and will not be described in detail here.
[0047] In this embodiment, the control host can be controlled by pressing the corresponding control key on the touch screen of the LCD controller 106. At the same time, a main switch is fixed on the housing 10. The main switch is electrically connected to the control host. The whole machine can be turned on or off by pressing the main switch. The main switch is not shown in the attached drawings. It is also a conventional structure and will not be described in detail here.
[0048] In use, the fan 30 operates, allowing external air to enter the first gas collection hood 15 through the transverse air guide holes of the outer baffle 14. After being filtered by the filter plate 152, the air is discharged from the gas collection outlet sleeve 151 into the main operating chamber 102. After being filtered by the filter sleeve 35, the air enters the volute of the fan 30, and then enters the pipeline connected to the outlet end of the outlet connector 12 through the outlet pipe and outlet connector 12. This supplies air to the equipment connected to the other end of the pipeline, allowing for operations such as cooling of the connected inner cavity of the equipment.
[0049] When the bottom drive motor 31 of the fan 30 is running, it will draw external gas into the control chamber 101 through the corresponding ventilation holes, and then into the first air guide pipe 150 through the air intake filter cylinder 111. When the gas enters the control chamber 101, it can first enter the control chamber 101 for heat exchange and cooling, and then enter the air intake filter cylinder 111. Therefore, the control chamber 101 also has a cooling effect.
[0050] The gas entering the first air duct 150 enters the bottom drive motor 31, cools and heats the inside of the bottom drive motor 31, and is discharged from the exhaust pipe 32. When discharged, it passes through the sound insulation filter cotton 161 to achieve sound insulation and noise reduction.
