Description

Technical Field

[0001] The utility model relates to a hot air breaking device of a vacuum drying box. Background Art

[0002] The air breaker in a vacuum drying oven is primarily used to safely introduce clean air into the chamber after the drying process, restoring the chamber to normal pressure. This breaker typically consists of a filter assembly and a manual breaker valve. The filter assembly can be a high-efficiency filter that removes impurities such as dust and microorganisms, ensuring the cleanliness of the incoming air. The breaker valve controls the rate and volume of air entering the chamber, preventing a rapid influx of air that could damage samples or the internal structure of the equipment. After drying is complete, the breaker valve is opened to allow purified air to slowly enter the drying chamber, balancing the internal and external pressures. The chamber door can then be opened to remove the items. However, the air in the air breaker in conventional vacuum drying ovens is often un-dried and retains a certain amount of humidity. Directly transferring this air through the manual valve and capsule filter to release pressure inside the chamber can negatively impact the dried material and fail to guarantee its dryness.

[0020] Example

[0021] Reference Figures 1 to 3 This embodiment provides a hot air breaking device for a vacuum drying oven, including an air storage tank 1, a heating pipe 2, an air inlet pipe 3, an air outlet pipe 4, an automatic regulating valve 5, a capsule filter 6 and a connecting pipe 7. The heating pipe 2 is arranged in the air storage tank 1 for heating the air, one end of the air inlet pipe 3 is arranged on one side of the air storage tank 1, and the other end of the air inlet pipe 3 is connected to the external air delivery pipe. One end of the air outlet pipe 4 is arranged at the other end of the air storage tank 1, and the automatic regulating valve 5 is arranged at the end of the air inlet pipe 3 connected to the external air delivery pipe for controlling the speed and amount of air entering. The capsule filter 6 is arranged at the other end of the air outlet pipe 4 for filtering the air. The capsule filter 6 is connected to the interior of the vacuum drying oven 13 through the connecting pipe 7.

[0022] The air-breaking device mainly consists of an air tank 1, a heating pipe 2, an air inlet pipe 3, an air outlet pipe 4, an automatic regulating valve 5, a capsule filter 6 and a connecting pipe 7. The air tank 1 serves as the installation base of the device. A heating pipe 2 is installed on the top of the air tank 1 to heat the air entering the air tank 1. An air inlet pipe 3 is installed on the left side of the bottom of the air tank 1. The air outlet end of the air inlet pipe 3 is connected to the interior of the air tank 1, and the air inlet end of the air inlet pipe 3 is connected to the external air delivery pipeline. The air inlet pipe 3 is in an L-shaped structure, so that the outside air can enter the air storage tank 1 more easily. An air outlet pipe 4 is installed on the right side of the top of the air storage tank 1. The air inlet end of the air outlet pipe 4 is connected with the inside of the air storage tank 1, so that the high-temperature air in the air storage tank 1 can enter the air outlet pipe 4. An automatic regulating valve 5 is installed at the air inlet end of the air inlet pipe 3. The speed and amount of air entering the air inlet pipe 3 can be controlled by the automatic regulating valve 5 to prevent the rapid influx of air from damaging the internal structure of the material or equipment. The air filter 6 is a kind of air filter that is used to purify the air and remove the impurities such as dust, bacteria, viruses, etc. ...

[0023] Furthermore, a first flange 8 is provided on the top of the gas storage tank 1, and a second flange 9 matching the first flange 8 is provided on the top of the heating tube 2. The first flange 8 is connected to the second flange 9 by bolts.

[0024] In this embodiment, a first flange 8 is installed on the top of the gas storage tank 1, and a second flange 9 that matches the first flange 8 is installed on the top of the heating tube 2. The first flange 8 and the second flange 9 are fixedly connected by bolts to ensure the sealing between the heating tube 2 and the gas storage tank 1 and prevent hot air from overflowing from the gas storage tank 1.

[0025] Furthermore, a temperature sensor 10 is provided at the bottom of the gas storage tank 1 .

[0026] In this embodiment, a temperature sensor 10 is installed at the bottom of the gas storage tank 1 to measure the temperature of the hot air in the gas storage tank 1 and transmit the measured data to a display so that the temperature of the hot air in the gas storage tank 1 can be easily viewed. This prevents the heating pipe 2 from continuously heating the air in the gas storage tank 1, and ensures that the heating temperature is stabilized at a certain set value.

[0027] Furthermore, an over-temperature alarm sensor 11 is provided on one side of the top of the gas storage tank 1 .

[0028] In this embodiment, an over-temperature alarm sensor 11 is installed on the left side of the top of the gas storage tank 1. If the temperature sensor 10 is damaged and the heating tube 2 continues to heat the air in the gas storage tank 1 to a certain value, the over-temperature alarm sensor 11 can sound an alarm, so that the heating of the heating tube 2 can be stopped in time, thereby providing a certain degree of protection for the device.

[0029] Furthermore, a sealing gasket 12 is provided between the first flange 8 and the second flange 9 .

[0030] In this embodiment, a sealing gasket 12 is installed between the first flange 8 and the second flange 9 to improve the sealing between the first flange 8 and the second flange 9, thereby further improving the sealing of the connection between the heating pipe 2 and the gas tank 1, preventing the hot air in the gas tank 1 from leaking, and ensuring the safe use of the device.

[0031] Furthermore, the material of the automatic regulating valve 5 is stainless steel.

[0032] The automatic regulating valve 5 in this embodiment is made of stainless steel. Stainless steel has good corrosion resistance and mechanical properties, so that the automatic regulating valve 5 can withstand certain temperatures and pressures to ensure that it can work normally.

[0033] During use, the automatic regulating valve 5 is first opened to allow the air in the external air delivery pipe to slowly enter the air inlet pipe 3 and then enter the air storage tank 1 through the air inlet pipe 3. Then, the heating pipe 2 is turned on to heat the air entering the air storage tank 1 through the heating pipe 2. During this process, the temperature sensor 10 monitors the air temperature in the air storage tank 1. After the air is heated, the hot air in the air storage tank 1 flows through the air outlet pipe 4 to the capsule filter 6. The heated hot air is filtered by the capsule filter 6 to ensure the quality of the purified air and prevent it from contaminating the dried material. The filtered hot air finally flows into the vacuum drying box 13 through the connecting pipe 7, and the vacuum drying box 13 is broken. The air is heated by the heating pipe 2, which removes the humidity in the air and reduces the effect of the broken air on the dryness of the dried material, thereby ensuring the dryness of the material. The high temperature air also helps to evaporate the residual water vapor in the dried material and the volatilization of the residual volatile organic compounds, further improving the quality of the material.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
