Description

Technical Field

[0001] This utility model relates to the field of dry well furnace technology, and more particularly to an 8-channel temperature calibration dry well furnace. Background Technology

[0002] Dry well temperature metrology furnaces, also known as dry wells, dry-body furnaces, dry well furnaces, dry-type metrology furnaces, temperature metrology furnaces, and temperature calibrators, are portable, fast-heating and cooling, and the most traditional on-site heat source (temperature field). They are widely used in industries requiring on-site temperature calibration, such as pharmaceuticals (GMP moist heat sterilization, dry heat sterilization), biological products, power plants and substations, steel mills, metrology and testing, and scientific research.

[0003] Currently, when using a dry well furnace, after placing a heat spreader, a temperature probe is inserted into the bottom of the heat spreader in the dry well. After the dry well has been balanced for a period of time and reaches the user's required temperature, the temperature probe is calibrated. The temperature probes currently on the market have a relatively long and thin insertion end, which makes them prone to damage during insertion.

[0004] Temperature calibrators are used in industrial settings where temperature is a crucial element. Temperature is typically measured using field sensors (PT100 RTDs, thermocouples, etc.) and field display instruments (digital displays, temperature controllers, recorders, etc.). Over time, the accuracy of these instruments may gradually decrease, impacting product quality and production.

[0005] In aero-engine manufacturing, especially in the research on the comprehensive measurement and calibration technology of aerodynamic performance parameters of compression components in civil aviation turbofan engines, the measurement of the temperature of the rear section of the high-pressure compressor support plate is involved. The probe used for measurement is a high-temperature irregularly shaped multi-point temperature sensor. However, after the sensor is accepted at the factory, the probe temperature is not calibrated again. In order to monitor the accuracy of the probe temperature measurement during use, a dedicated dry well furnace for high-temperature irregularly shaped multi-point temperature sensors is required. However, the dry well furnace structure for high-temperature sensors lacks a high-temperature body and a temperature equalization block that can be assembled together. This not only hinders the assembly and positioning detection but also results in poor control accuracy and stability, which needs to be improved.

[0006] Chinese patent CN217276585U discloses a novel portable temperature dry well metering furnace, comprising a dry well furnace. The furnace is characterized by: a display screen mounted obliquely on one side of its top; side plates fixedly mounted on both sides of the top; a connecting plate mounted on the two sets of side plates via a pivot; and a cylindrical handle mounted between the two sets of connecting plates via a pivot. This design, with its side plates, connecting plates, and cylindrical handle, makes the device easy to carry. The cylindrical handle provides a more comfortable grip, and the rotatable mounting of the connecting plates and side plates allows for placement on one side without affecting the use of the dry well furnace. Furthermore, the design includes a support column, crossbar, and collar. When using an external temperature probe, the support column can be pulled upwards via the protruding column, and the collar can be moved directly above the temperature control port. The external temperature probe can then be inserted through the collar and into the temperature control port, allowing it to be lowered vertically and preventing damage to the slender bottom portion of the probe.

[0007] Chinese patent CN214843711U discloses a dry well furnace temperature calibrator, comprising a body, a processing module, a control module, a sound generation module, a display screen, and a Bluetooth module. The key features are: a back plate is fixedly installed on the rear wall of the body; a baffle is provided on the top of the body; a spring is installed between the back plate and the body, with its upper end fixedly connected to the lower end of the baffle; sliding grooves are provided on both the left and right sides inside the body; sliders are fixedly installed on the left and right side walls of the baffle at positions corresponding to the sliding grooves, with the sliders slidably connected to the sliding grooves; and a limit block is fixedly installed on the front side of the bottom wall of the baffle, with the front wall of the limit block having an opening... The device features an installation slot with a transmission block at its front end. A spring piece, fixedly connected to the transmission block, is installed inside the installation slot. A limit groove is located on the front side of the machine body corresponding to the installation slot, and a push block is movably installed on the front side of the limit groove. This design addresses the issue of the dry well furnace temperature calibrator. Because the machine body has a sliding groove, and the baffle is movably connected to the sliding groove via a slider, the baffle can slide along the sliding groove. The sliding of the baffle within the sliding groove stretches the spring. When not in use, the baffle can be pushed downwards, causing the limit block on the baffle to move into the limit groove. When the transmission block on the limit block contacts the limit groove, it causes the transmission block to... The rear-moving compression spring, when the limiting block is fully moved into the limiting groove, the transmission block loses its squeezing force and is pushed to the rear of the push block by the elastic force generated by the spring. Since the limiting groove is L-shaped, the spring moving to the rear of the push block fixes the limiting block in the limiting groove, thus placing the baffle in front of the display screen. This prevents stains from falling on the display screen when not in use, which would obstruct the display screen and make it difficult to see the content when in use. To use this dry well furnace temperature calibrator, simply press the push block, which pushes the transmission block to the rear, causing the transmission block to be pushed to the rear by the push block. When the device moves into the mounting slot, the limiting block loses its fixing force. At this time, the spring, having lost its tension, releases the opposite force, pulling the baffle backward. Since one side of the back plate is sloping, when the baffle contacts the sloping side of the back plate, the dirt on the baffle surface is scraped off by the sloping side of the back plate, achieving an automatic cleaning effect. This dry well furnace temperature calibrator has two sets of buffer plates installed at the bottom of the machine body. The buffer plates can increase the protection of the machine body's corners when the machine body collides with the ground. The bottom of the buffer plates is also equipped with support legs, which prevent the mud on the ground from affecting the machine body when the machine body is placed on the ground.
