Detailed Description
As shown in the attached drawing 1, the utility model discloses a first room 1 and through siphon pipeline 3 with the second room 4 that first room 1 is linked together, siphon pipeline 3's both ends respectively with the intercommunication of first room 1 and second room 4 be provided with the breather pipe 6 that is used for first room 1 and atmosphere intercommunication on first room 1, correspond in the position of second room 4 and be provided with the attemperator that is used for adjusting the temperature of second room 4. The first chamber 1 is provided with a first fluid outlet 2, the second chamber 4 is provided with a fluid inlet 5, two ends of the siphon pipeline 3 are respectively communicated with the first fluid outlet 2 and the fluid inlet 5, and the first fluid outlet 2 and the fluid inlet 5 are respectively positioned below the liquid level in the first chamber 1 and the second chamber 4. The temperature regulating device can act on the second chamber 4 only or on the whole device to heat the whole device, and the function is the same.
During the in-service use, can be at prefabricated reagent in second room 4, also can place the reagent package in second room 4, this reagent package can open under the effect of centrifugal force, and liquid in the reagent package enters into second room 4, to the structure of reagent package, can adopt the tip to utilize the hot pressing to bond the package column structure together and fix in second room 4, control hot pressing degree for the reagent package can be opened under certain centrifugal force, or also can adopt the acupuncture structure to open the reagent package. The temperature adjusting device adopts a semiconductor refrigerating sheet, and can heat or cool the second chamber 4.
When the siphon device is used, liquid is introduced into the first chamber 1 and the second chamber 4, and the two chambers are communicated in advance in order to prevent the liquid in the first chamber 1 from breaking through the limit of the siphon pipe 3, and the topmost position of the siphon pipe 3 is higher than the liquid level in the first chamber 1 and the second chamber 4. At this point there is a length of gas in the siphon 3 separating the liquid in the first and second chambers 1, 4 and there is now a sealed compressible medium above the liquid level in the second chamber 4. When the temperature of the second chamber 4 is raised by the temperature regulating means, the compressible medium in the second chamber 4 expands, whereby the liquid in the second chamber 4 is transported through the siphon line towards the first chamber 1 until the gas located in the siphon line 3 is evacuated through the first chamber 1, thereby achieving fluid communication between the second chamber 1 and the second chamber 2. The second chamber 4 is then cooled, the compressible medium in the second chamber 4 contracts, the liquid in the first chamber 1 is sucked into the second chamber 4, and the liquid is transported to the next step by the first flow channel 9. A second fluid outlet 8 is provided at the bottom of the second chamber 4, and a first flow passage 9 communicates with the second fluid outlet 8.
For the first flow channel 9, the outlet should be higher than the level of the first chamber 1, siphon conduit 3 and second chamber 4, so as to prevent liquid from draining out of the first flow channel 9 during the above process.
In addition to the above-described cooling operation, the first chamber 1, the second chamber 4, and the siphon 3 may be provided on the rotatable reagent disk 7 so that the liquid in the first chamber 1 is introduced into the second chamber 4, and the first chamber 1 is located radially inward of the second chamber 4 (i.e., the distance between the first chamber 1 and the rotation axis of the reagent disk is smaller than the distance between the second chamber 4 and the rotation axis of the reagent disk). The minimum distance between the siphon pipe 3 and the center of rotation should be smaller than the minimum distance between the liquid level in the first and second chambers 1 and 4 and the center of rotation. The liquid in the first chamber 1 is brought to centrifugal force by increasing the rotational speed of the reagent disk 7, and the liquid is transported from the first chamber 1 to the second chamber 4 by the centrifugal force.
The two ends of the siphon pipe 3 of the present invention are not necessarily communicated with the bottom ends of the first chamber 1 and the second chamber 4. When communicating with the bottom ends of the first and second chambers 1 and 4, the liquid in the first and second chambers 1 and 4 can be completely discharged. When the siphon pipe 3 is connected to the middle of the first and second chambers 1 and 4, it is also ensured that the first fluid outlet 2 and the fluid inlet 5 are located below the liquid level of the respective chambers, and at this time, only the liquid located above the first fluid outlet 2 and the fluid inlet 5 can be transferred to other chambers, and the liquid below cannot be transferred. Although this design does not allow all of the liquid in the chamber to be transported away, there are specific applications where this is desirable, for example when there are solid particles that settle in the first chamber 1 and it is only the supernatant liquid that is to be transported away.
The utility model provides a function is similar to fluid control module of valve, and the liquid in first room 1 and the second room 4 does not switch on under conventional state, and under specific conditions, realizes that the liquid in first room 1 and the second room 4 switches on to satisfy the demand that needs add liquid at specific time when the reagent dish is using. Finally, it should be noted that in the present application, the radially inner and the radially outer are both relative to the center of rotation of the reagent disk 7.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
