The liquid medicine is heated to a certain temperature, heat preservation is carried out for a certain time, the actual temperature in the tank body in the sterilization process is monitored in real time, and the preset operation condition is ensured to be met. As shown in fig. 1, the preparation tank includes a tank body 1 and a tank lid 3; a jacket 2 is arranged outside the tank body 1; two sides of the tank bottom are respectively provided with a temperature probe 5 and a magnetic stirrer 4. When in sterilization operation, steam is introduced into the jacket 2 to heat the tank body; the magnetic stirrer 4 at the bottom stirs to ensure that the temperature of the liquid medicine in the tank body is as uniform as possible; the temperature of the liquid medicine is detected by the temperature probe 5. When the temperature probe 5 is qualified and the sterilization temperature record is not abnormal, the situation of poor sterilization effect happens occasionally.

SUMMERY OF THE UTILITY MODEL

After the analysis, the inventor considers that: the temperature of the preparation tank in the stirring process is mostly monitored through a temperature probe carried by the equipment, although the preparation tank is in stirring operation, the distribution of cold and hot spots is not necessarily uniform, whether the temperature probe carried by the tank can truly represent the lowest temperature of the liquid medicine or not needs to be confirmed through verification, and a better device and method are not provided in the industry at present. Therefore, the temperature correction device and the correction method for the preparation tank are important for confirming whether the temperature probe of the tank body really reflects the temperature of the liquid medicine or not through verification and then carrying out corresponding temperature compensation to ensure the sterilization effect and realize in-situ sterilization.

The utility model aims at providing a temperature correcting device of a preparation tank, which has novel and unique structure and convenient use and can effectively correct sterilization equipment; the specific technical scheme is as follows:

a temperature correction device for a preparation tank comprises a probe bracket and a plurality of correction probes; the probe bracket is provided with a plurality of layers from top to bottom and is supported by a plurality of vertically arranged screw rods; each layer is provided with 1 annular or a plurality of concentric annular probe mounting plates from inside to outside, and the correction probes are mounted on the probe mounting plates; the probe mounting plates on the same layer are fixedly connected through a cross beam.

Furthermore, the correction probes are uniformly distributed along the circumferential direction of the probe mounting plate.

Furthermore, each layer of the probe mounting plate is uniformly distributed from top to bottom.

Further, the interval between the maximum outer edge of the probe mounting plate and the inner wall of the tank body is larger than 5 cm.

The temperature correction device of the preparation tank monitors the temperature field of the liquid medicine in the tank body during working through the arranged correction probe array, finds the lowest temperature value in the temperature field of the liquid medicine, and corrects the temperature probe, so that a low-temperature region lower than the sterilization temperature cannot appear in the preparation tank; the sterilization effect is ensured.

Detailed Description

The present invention will be more fully described with reference to the following examples. The present invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

For ease of description, spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 2, the temperature calibration device for the preparation tank in the present embodiment includes a probe holder and a plurality of calibration probes 605; the probe bracket is provided with a plurality of layers from top to bottom and is supported by a plurality of vertically arranged screw rods 604; each layer is provided with 1 annular probe mounting plate 602, and the middle part is provided with a cross beam 603; the beam 603 passes through the center of the annular probe mounting plate 602, and both ends of the beam are bridged on the mounting plate 602. The calibration probe 605 is mounted on the probe mounting plate 602 and on the cross beam 603; the probe mounting plates on the same layer are fixedly connected through a cross beam 603. A plurality of concentric ring-shaped probe mounting plates 602 can be arranged from inside to outside on each layer; the probe mounting plates 602 are connected together by a cross beam 603.

For convenience in processing, the correction probes are uniformly distributed along the circumferential direction of the probe mounting plate.

The probe mounting plates of all layers are uniformly distributed from top to bottom as far as possible.

In order to avoid scratching the tank wall during installation, the interval between the maximum outer edge of the probe installation plate and the inner wall of the tank body is more than 5 cm.
