Description

Technical Field

[0001] This utility model belongs to the field of biomedical equipment, specifically relating to a lifting probe bracket for a constant temperature oil bath. Background Technology

[0002] Portable thermostatic oil baths are high-precision temperature control devices that play a crucial role in the biopharmaceutical field. These devices feature automatic temperature control with high accuracy, capable of real-time monitoring and precise display of the bath temperature, effectively ensuring temperature accuracy and stability. Simultaneously, the equipment is equipped with a stirring motor to ensure uniform temperature distribution within the liquid. Portable thermostatic oil baths are widely used for calibrating various temperature sensors in clean production processes, including temperature probes in pharmaceutical bioreactors and other equipment.

[0003] In existing technologies, temperature probe calibration typically requires manually inserting the probe into silicone oil. When the thermostatic oil bath is activated, the agitator causes the silicone oil to swirl. However, due to the lack of a dedicated temperature probe securing device, the probe is prone to slipping and sinking directly into the silicone oil. This not only leads to inaccurate calibration data, requiring repeated calibration and wasting time, but also poses a significant safety hazard, as the probe may fall into the stirring area, causing the agitator to jam or even damaging the equipment.

[0004] In industries such as pharmaceuticals, biotechnology, and food manufacturing, hygienic temperature sensors are widely used in process control and require regular calibration. Calibration typically necessitates production stoppages, thus calibration efficiency directly impacts downtime. To improve calibration efficiency, shorten downtime cycles, and ensure equipment safety, there is an urgent need to develop a device capable of securely fixing temperature probes for calibration operations in constant-temperature oil baths.

[0030] To make the various technical features, advantages, or effects of the present invention more apparent and understandable, detailed descriptions are provided below through embodiments.

[0031] like Figure 1 As shown, this embodiment provides a lifting probe bracket 10 for a constant temperature oil bath, including an outer ring 11, a probe plate 12, a perforated base plate 13, a fixing screw 14, and an adjusting screw 15.

[0032] The outer ring 11 has an annular structure and is fitted onto the upper opening of the constant temperature oil bath to support the entire support structure. The perforated base plate 13 is located below the outer ring 11 and is connected to the outer ring 11 by at least two parallel fixing screws 14. The upper end of the fixing screw 14 is threaded to the outer ring 11, and the lower end is threaded to the perforated base plate 13. The two are screwed together to form a stable support frame.

[0033] The probe plate 12 is positioned between the fixing screws 14, and its body has multiple probe holes, such as seven, for inserting temperature probes 20. The probe plate 12 has round holes for the fixing screws 14 to pass through, allowing the fixing screws 14 to slide up and down on the probe plate 12, thereby adjusting the height in conjunction with the adjustment device.

[0034] An adjusting screw 15 is located on the upper end of the outer ring 11. Its upper end is threaded to the outer ring 11, and its lower end is threaded to the probe plate 12. The adjusting screw 15 and the probe plate 12 have a height-adjustable structure. Preferably, a wing nut is threaded onto the upper end of the adjusting screw 15 for easy manual adjustment. By rotating the wing nut, the probe plate 12 can be moved up and down along the axis of the adjusting screw 15, thereby achieving precise adjustment of the insertion depth of the temperature probe 20.

[0035] The probe holes on the probe plate 12 are evenly distributed, allowing up to seven temperature probes 20 to be inserted at a time, thus improving calibration efficiency. Each hole is sized to fit the probe tightly and features a sealing structure to ensure a good seal between the probe and the probe plate 12, preventing silicone oil ingress and ensuring a stable calibration environment.

[0036] To enhance the corrosion resistance and high temperature resistance of the overall structure, the outer ring 11, probe plate 12, perforated base plate 13, fixing screw 14 and adjusting screw 15 are all made of stainless steel, which is suitable for long-term use in the high temperature environment inside the oil tank.

[0037] The standard operating procedure (SOP) for this probe holder is as follows:

[0038] Step 1: Install the probe bracket

[0039] Place the probe bracket 10 vertically into the oil furnace hole 31 of the constant temperature oil bath 30, ensuring that the outer ring 11 is firmly secured at the edge of the oil bath opening, so that the entire bracket is stably in place (see...). Figures 6 to 7 ).

[0040] Step 2: Adjust the height

[0041] Observe the level of silicone oil in the oil tank, rotate the wing nut on the outer ring 11, and adjust the position of the adjusting screw 15 to move the probe plate 12 up and down. Adjust the probe plate 12 to a suitable position slightly higher than the oil level to ensure that the temperature probe 20 is not completely submerged in the oil when inserted, and to facilitate fixing and replacement.

[0042] Step 3: Insert the temperature probe

[0043] Insert the temperature probe 20 with the connected wires into the respective probe holes on the probe plate 12 in sequence (see...). Figure 5 Ensure the probe is inserted vertically and to a consistent depth. Pay attention to the tight fit between the probe and the hole, avoiding any shaking or tilting.

[0044] Through the above structural design, the lifting probe bracket provided in this embodiment can effectively prevent the probe from slipping during the calibration process, ensure equipment safety, improve calibration accuracy and efficiency, and is suitable for industries with high temperature control accuracy requirements, such as biopharmaceuticals.

[0045] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any appropriate modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention should be covered within the protection scope of the present invention, which is defined by the claims.
