As shown in fig. 5, 6 and 7, the first connecting rope 43 and the second connecting rope 44 are respectively wound out from the upper side and the lower side of the driving wheel 41, as shown in fig. 7, therefore, when the motor 42 rotates, the driving wheel 41 can be pulled to rotate through the first connecting rope 43 to drive the cylinder cover 39 to open, when the motor 42 reversely rotates, the cylinder cover 39 can be pulled through the second connecting rope 44 to apply downward force to the cylinder cover 39, especially after the cylinder cover 39 has contacted the processing cylinder 2, the driving wheel 41 can be pulled through the second connecting rope 44 continuously in a tensioning manner, so that the driving wheel 41 can apply downward rotation moment to the cylinder cover 39, and the compacting and sealing effect between the cylinder cover 39 and the processing cylinder 2 is further ensured. After the cylinder cover 39 is contacted with the treatment rod by adopting the form that the driving wheel 41 is driven by the connecting rope 55, when the driving wheel 41 and the cylinder cover 39 are driven to rotate towards the closed position by the second connecting rope 44, the second connecting rope 44 is tensioned to tightly press the cylinder cover 39 on the treatment cylinder 2, the tensile strength of the second connecting rope 44 is larger and not easy to damage, and the second connecting rope 44 is not easy to deform and damage and is more stable to use under the condition of adopting the rigid component driving moment relatively.

Further, the speed changing assembly further comprises a speed changing wheel 45, the speed changing wheel 45 comprises an input wheel portion 4501 and an output wheel portion 4502, the wheel diameter of the input wheel portion 4501 is larger than that of the output wheel portion 4502, the input wheel portion 4501 is in transmission connection with the driving wheel 40, and the output wheel portion 4502 is in transmission connection with the first connecting rope 43 and the second connecting rope 44.

Further, in the embodiment shown in fig. 13, the dehydrator further includes: the basket 69 comprises a basket body 70 with a placing cavity and a magnetic induction piece 71, wherein the placing cavity is suitable for providing a placing space for vertically stacking the embedding boxes 76, the magnetic induction piece 71 and the basket body 70 are of a split structure, and the magnetic induction piece 71 can be placed in the placing cavity; a magnetic sensor 72 disposed outside the fixed cylinder 1, wherein the magnetic sensor 72 obtains a trigger signal of the magnetic sensor 71 when the magnetic sensor 71 moves to a set position in the processing chamber; and a processor connected with the travelling mechanism and the magnetic sensor 72, wherein the processor is suitable for judging the position of the magnetic induction piece 71 in the basket body 70 according to the lifting stroke of the travelling mechanism after acquiring the trigger signal.

When the tissue dehydration device is used, the embedding boxes 76 are vertically stacked in the placing cavity, then the magnetic induction piece 71 is placed on the upper side of the embedding box 76 at the uppermost side in the accommodating cavity, when the lifting basket 69 is driven by the travelling mechanism to be placed in or taken out of the fixed cylinder 1, when the magnetic induction piece 71 moves to a set position, the magnetic sensor 72 acquires the position information of the magnetic induction piece 71, and at the moment, the processor can judge the relative position of the magnetic induction piece 71 in the basket body 70 according to the travel of the travelling mechanism, so that the number of the embedding boxes 76 in the basket body 70 can be judged.

For the setting judged by the processor, specifically, the upper limit position and the lower limit position of the travelling mechanism for driving the basket body 70 to lift can be set as reference positions, when the connecting end connected with the basket body 70 on the travelling mechanism is at the upper limit position, the basket body 70 is fixed at the connecting part 58, the travelling mechanism starts to drive the basket body 70 to move downwards, at this time, the processor starts to record the downward movement of the travelling mechanism, when the magnetic induction piece 71 moves downwards to trigger the magnetic sensor 72, the processor can determine the relative position of the magnetic induction piece 71 in the basket body 70 according to the recorded descending travel or descending time of the travelling mechanism, and further determine the number of corresponding embedded boxes 76. Or, when the basket body 70 is located in the processing cavity of the fixed cylinder 1, the connecting end of the travelling mechanism is connected with the basket body 70, the travelling mechanism is at a lower limit position, the processor records that the lifter moves upwards, and when the travelling mechanism drives the basket body 70 to move upwards to the magnetic induction piece 71 to trigger the magnetic sensor 72, the processor can determine the relative position of the magnetic induction piece 71 in the basket body 70 according to the recorded ascending travel or descending time of the travelling mechanism, so as to determine the number of the corresponding embedding boxes 76. The processor records the lifting time or travel of the travelling mechanism, establishes a corresponding relation with the position of the magnetic induction piece 71 relative to the basket body 70, and the part can adopt the existing processor only by adjusting corresponding parameters.

It can be seen from this that the dewatering device of the present invention can detect the number of the embedded boxes 76 of the basket 70 by arranging the magnetic sensor 72 at the outer side of the fixed cylinder 1, and can automatically detect when the basket 70 is put in or taken out, and is convenient to use; moreover, the magnetic sensor 72 is arranged on the outer side of the fixed cylinder 1, so that the mechanism for detecting the number of the embedding boxes 76 is not easy to contact with the reagent in the fixed cylinder 1, the use is more stable, the magnetic sensor 72 does not occupy the space on the upper side of the fixed cylinder 1, and other structural components above the walking mechanism or the fixed cylinder 1 are not interfered, so that the structure on the upper side of the fixed cylinder 1 is simplified.

Wherein, the processor can adopt the existing single machine processor.

It should be noted that the present invention is an improvement of the dehydration apparatus in that the number of the embedded boxes 76 placed in the basket 70 is not limited to other structural components of dehydrated tissues (such as heating units, ultrasonic processing units, and vacuum pumping units), and the other structural components may be selected from the existing ones.

Therefore, the positions of the embedding boxes 76 and the magnetic induction pieces 71 in the basket body 70 can be determined through the positioning ribs, so that the stacking effect of the embedding boxes 76 in the basket body 70 is ensured, and the detection accuracy of the magnetic induction pieces 71 can be improved. Specifically, only one array of embedded boxes 76 can be placed in the basket 70, and the walls of the placement cavity of the basket 70 form positioning ribs. In an alternative embodiment, a plurality of laterally spaced locating ribs may also be provided in the placement chamber to provide a plurality of rows of cassette 76 in the placement chamber.

In the illustrated embodiment, further specifically, a separation rib 73 is disposed in the fixed cylinder 1, and the separation rib 73 divides the processing cavity into at least two installation areas in the transverse direction, and the processing cavity is suitable for providing a placement space of the single basket 70 in the installation areas; the outside of the fixed cylinder 1 is respectively provided with the magnetic sensor 72 corresponding to each mounting area.

Thus, the processor can obtain the number of the embedding cassettes 76 when the travelling mechanism lifts the basket 70 by fixing the cylinder 1, and can control the amount of the liquid supplied from the liquid supplying member 75 to the processing cylinder 2 according to the number of the embedding cassettes 76 when the basket 70 is placed in the processing cylinder 2, and the amount of the liquid supplied to the processing cylinder 2 can be monitored by the flow sensor 74.

Preferably, the flow sensor 74 is a clamp-on flow sensor. By using a clamp type flow sensor, the installation is facilitated, and the flow sensor 74 is not in contact with the reagent, so that the stability of the use of the flow sensor 74 is maintained.
