Shell cover opening and closing force detection system for pneumatic sample-transporting shells and detection method

Abstract

The invention discloses a shell cover opening and closing force detection system for pneumatic sample-transporting shells and a detection method, which belong to the field of pneumatic sample-transporting shell cover opening and closing force detection. In the invention, a lower clamp, an upper clamp and a base plate are arranged on the outside of the same sidewall of an opening and closing device case, a handle is lifted or pressed to drive a cover-opening stress post or a cover-closing stress post, the upper clamp goes up or down along with the cover-opening stress post or the cover-closing stress post to open or close a cover, a pressure sensor is fixed in a socket on an internal connecting plate, and is in contact with the inserted end of the cover-opening stress post, and the pressure sensor is connected with a force measurement control box; and the force measurement control box comprises a singlechip, a display module, a signal-holding circuit module, an A / D (analog-to-digital) conversion module, an alarm module, an external crystal oscillator and resetting module and a starting circuit module. The invention uses the singlechip to realize the low-cost acquisition, processing and display of transient peak signals, solves the problem that sample can be easily lost in the process of pneumatic sample transportation because the magnitude of the opening and closing force of a sample-transporting shell cover and a sample-transporting shell body cannot be controlled, and enhances the reliability of quality management.

Description

technical field [0001] The invention belongs to the technical field of detecting the opening and closing force of the shell cover in the pneumatic sample delivery system of a steelmaking plant, and more specifically relates to a detection system and a detection method for the opening and closing force of the shell cover of the pneumatic sample delivery system, especially suitable for snap-fit ​​wind The opening and closing force detection of dynamic sample feeding shells. Background technique [0002] At present, during the testing and sampling process of molten steel in a steelmaking plant, the staff need to put the steel sample slag sample collected when the smelting is about to be released into a shell (that is, the container containing the sample), and then send the shell to the sample through the wind. The pipeline system is quickly sent to the laboratory for testing, and the empty shells after the test are returned to the sending cabinet next to the converter through t...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the problem in the prior art that the opening and closing force of the sample delivery projectile cover cannot be detected and sensed, resulting in the easy loss of samples in the sample delivery projectile, and provides a detection system for the opening and closing force of the pneumatic sample delivery projectile cover and detection method, through the technical solution of the present invention to collect the maximum value of the uncapping force of the air-driven sample delivery projectile, the timely detection and display of the sample delivery projectile decap force can be realized, thereby avoiding the sample in the sample delivery projectile to the greatest extent. lost accident
