Embodiment Construction

[0011] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0012] The present invention is a novel wind speed measurement system applied to a tunnel type sterilization oven, such as figure 1 Shown is a schematic diagram of the use of a new wind speed measurement system applied to a tunnel-type sterilization oven. The air outlet of the fan 4 is connected to the air duct 5 by a flange, and the middle section of the pitot tube 3 is welded to the air duct 5, so that one end of the pitot tube 3 is located in the air duct 5, and the pitot tube in the air duct 5 The port at one end of 3 is facing the air duct opening of air duct 5, that is, the top of Pitot tube 3 must face the windward side and maintain parallel. The two ports at the other end of the pitot tube 3 are respectively connected to the two ports of the differential pressure transmitter 1 through two gas pipes 2 . Utilize wind cover...

Abstract

The invention discloses a novel air speed metering system utilizing a tunnel type sterilizing oven. The novel air speed metering system is characterized by comprising a Pitot tube, wherein one end of the Pitot tube is disposed in an air duct while the other end of the Pitot tube is connected with a pressure difference transmitter through an air tube. The novel air speed metering system has the advantage of capability of metering air speed of the inside of the sterilizing oven accurately.

Description

technical field [0001] The invention relates to a novel wind speed measurement system applied to a tunnel-type sterilization oven, through which the wind speed inside the tunnel oven box can be measured, and belongs to the field of tunnel oven wind speed measurement systems. Background technique [0002] The wind speed is an important indicator of the tunnel oven. If the wind speed does not meet the requirements, it will not be able to reach the 100-level laminar flow. The lack of class 100 laminar flow protection inside the tunnel oven is an important reason why it cannot pass the verification. In equipment without class 100 laminar flow protection, some containers may be re-contaminated after sterilization, thus failing to meet the sterilization requirements. For this reason, the wind speed of the tunnel oven has received widespread attention. [0003] At present, the commonly used wind speed measurement method is to use the impeller type or hot wire wind speed sensor for...
