[0003] Among them, in the process of solution stratification operation, the solution is first loaded into the centrifuge bottle, and then the centrifuge bottle is driven by the turntable to rotate at high speed to generate centrifugal force, and the solution in the centrifuge bottle is stratified by the centrifugal force to achieve the purpose of solution stratification.

[0004] In addition, the material of the centrifuge bottle varies according to the requirements of the application. When the requirements for solution stratification are not high, stainless steel and other metal materials can be used to make centrifuge bottles, so that the centrifuge bottles can be recycled; but in medical and other occasions with high cleanliness requirements, plastic centrifuge bottles must be used for inspection or testing.

[0005] Whether it is a plastic centrifuge bottle or a metal centrifuge bottle, they are composed of a bottle cap with an internal thread and a bottle body with an external thread, which has the following defects:

[0006] (1) If it is tightened too much, it will be difficult to open. If it is loosened, the seal will not be good during centrifugation, which is inconvenient to use. At the same time, the solution may flow out during centrifugation.

[0007] (2) The centrifugal separation effect of the three-phase materials containing water, organic esters and solids is poor, and the solid materials are easily contaminated by organic esters.

[0025] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0026] See also Figure 1 The centrifugal container 100 for solution stratification of the present invention is applied to a centrifuge and is mounted on a turntable of the centrifuge when in use. The turntable of the centrifuge drives the centrifugal container 100 for solution stratification to perform centrifugal rotation, thereby achieving the purpose of stratifying the materials contained in the centrifugal container 100 for solution stratification.

[0027] Recombination Figure 2 The centrifugal container 100 for solution stratification of the present invention comprises a cavity 10, a cover 20, a first valve 30, a second valve 40, a blind cover 50, a first clamp 60, a second clamp 70, a third clamp 80 and a plunger 90a. The cover 20 is assembled and connected with the cavity 10 in a sealed manner, which facilitates the operation of adding materials into the cavity 10 on the one hand, and prevents the materials in the cavity 10 from leaking from the matching part between the cavity 10 and the cover 20 on the other hand. A quick connector 13 and a tee 14 connected to the internal space 12 of the cavity 10 are respectively fixed on the side wall 11 of the cavity 10. Optionally, as an example, the quick connector 13 can be welded to the side wall 11 of the cavity 10. Obviously, according to actual needs, the quick connector 13 can also be threadedly connected to the side wall 11 of the cavity 10.

[0028] At the same time, the quick connector 13 is located above the three-way pipe 14, and the quick connector 13 is also connected to the first valve 30 in a sealed manner by means of the first clamp 60. On the one hand, it is convenient for the quick assembly and disassembly between the first valve 30 and the quick connector 13, and on the other hand, it can prevent the material from leaking from the fitting point between the first valve 30 and the quick connector 13; optionally, as an example, the first valve 30 is a ball valve, so that the first valve 30 has the effect of small rotational torque and good closing tightness. Obviously, according to actual needs, the first valve 30 can also be other types of valves.

[0029] Furthermore, the three-way pipe 14 has a first end 141, a second end 142 that is linearly connected to the first end 141, and a third end 143 that intersects and connects with the first end 141. The first end 141 of the three-way pipe 14 is fixedly connected to the side wall 11 of the cavity 10; optionally, as an example, the first end 141 of the three-way pipe 14 can be welded to the side wall 11 of the cavity 10. Obviously, according to actual needs, the first end 141 of the three-way pipe 14 can also be threadedly connected to the side wall 11 of the cavity 10; in addition, Figure 1 and Figure 2As an example, the first end 141 of the three-way pipe 14 is perpendicular to the side wall 11 of the cavity 10, so as to facilitate the assembly operation between the first end 141 of the three-way pipe 14 and the side wall 11 of the cavity 10, and the third end 143 of the three-way pipe 14 is perpendicular to the first end 141, and the third end 143 of the three-way pipe 14 is also arranged downward to better meet the need of the organic ester after stratification to flow out from the second valve 40 below; obviously, according to actual needs, the direction of the third end 143 of the three-way pipe 14 can also be other, as long as it is ensured that the organic ester can flow out from the second valve 40, so it is not necessary to Figure 1 and Figure 2 Limits shown.

[0030] Furthermore, the plunger 90a is cooperatively placed in the first end 141 and the second end 142 of the three-way pipe 14, so that the plunger 90a acts as a valve core to control the connection and disconnection between the first end 141 and the third end 143 of the three-way pipe 14; the first end 91 of the plunger 90a also protrudes from the side wall 11 of the cavity 10 by a distance D (see Figure 2 ) is 0.2 mm to 2 mm to prevent solids in the material from entering the interior of the tee 14 and the interior of the second valve 40 and contaminating the organic ester; the second end 92 opposite to the plunger 90a is assembled and connected to the blind cover 50, and the blind cover 50 is also connected to the second end 142 of the tee 14 in a sealed manner with the help of the second clamp 70. On the one hand, it is convenient for the blind cover 50 to be quickly assembled and disassembled with the second end 142 of the tee 14, and on the other hand, it can prevent leakage at the fitting point between the blind cover 50 and the second end 142 of the tee 14. The second valve 40 is connected to the third end 143 of the three-way pipe 14 in a sealed manner by means of the third clamp 80, which facilitates the quick assembly and disassembly operation between the second valve 40 and the third end 143 of the three-way pipe 14, and prevents leakage at the fitting point between the second valve 40 and the third end 143 of the three-way pipe 14; optionally, as an example, the second valve 40 is a ball valve, so that the second valve 40 has the effect of small rotation torque and good closing tightness. Obviously, according to actual needs, the second valve 40 can also be other types of valves. More specifically, as follows:

[0031] like Figure 1 to Figure 2 As shown, as an example, the centrifugal container 100 for solution stratification of the present invention further includes a limiting member 90b, a limiting groove 93 is provided on the side wall of the plunger 90a, and the limiting member 90b penetrates the second end 142 of the three-way pipe 14 and is placed in the limiting groove 93. Figure 2 Therefore, the length of the plunger 90a pulled out from the three-way pipe 14 is controlled by the cooperation of the stopper 90b and the stopper groove 93, which improves the convenience of the operator to pull out or push in the plunger 90a through the blind cover 50. Figure 3As an example, the limiting groove 93 is a keyway with the notch 931 facing upward, and the limiting member 90b is a pin located directly above the limiting groove 93, so as to simplify the structure of the limiting member 90b and facilitate the manufacture of the limiting groove 93 and the plunger 90a. Figure 2 , the process of the plunger 90a being limited by the limiting member 90b is described as follows: Figure 2 When the plunger 90a shown slides to the left until the limiting member 90b abuts against the groove end wall 931 on the right side of the limiting groove 93, the pull-out length of the plunger 90a is blocked by the abutment between the groove end wall 931 and the limiting member 90b; when the limiting member 90b abuts against the groove end wall 932 on the left side of the limiting groove 93, the distance D of the plunger 90a protruding from the side wall 11 of the cavity 10 is blocked by the abutment between the groove end wall 932 and the limiting member 90b; therefore, through the cooperation between the limiting member 90b and the limiting groove 93, the plunger 90a can be quickly and accurately switched between the closed and open states.

[0032] like Figure 1 As shown, as an example, the quick connector 13 is around the upper and lower center lines of the cavity 10 (see Figure 1 The three-way pipes 14 are arranged around the upper and lower center lines of the cavity 10, each quick connector 13 corresponds to a first clamp 60 and a first valve 30, and each three-way pipe 14 corresponds to a blind cover 50, a plunger 90a and a second valve 40; such a design ensures the stability of the dynamic balance of the centrifugal container 100 for solution stratification of the present invention during the rotation process, and facilitates the uniform outflow of water and organic esters. Specifically, Figure 1 As an example, the number of quick connectors 13 and tees 14 is the same, and each quick connector 13 is aligned with a corresponding tee 14 up and down, as shown in FIG. Figure 1 As shown, the stability of the dynamic balance of the centrifugal container 100 for solution stratification of the present invention during the rotation process is effectively improved; obviously, according to actual needs, the relationship between each quick connector 13 and a corresponding tee pipe 14 can also be other, so it is not shown in FIG. Figure 1 The following are the limits. Figure 1 and Figure 2 As an example, the second end 142 of the tee pipe 14 is provided with an outwardly protruding step structure 144 that cooperates with the blind cover 50, and the second clamp 70 holds the blind cover 50 and the step structure 144 from the outside, and a sealing ring 145 is clamped between the blind cover 50 and the step structure 144, which improves the convenience of assembly and disassembly between the blind cover 50 and the second end 142 of the tee pipe 14 on the one hand, and improves the reliability of the seal between the blind cover 50 and the second end 142 of the tee pipe 14 on the other hand. Figure 1As an example, the quick connector 13 is perpendicular to the side wall 11 of the cavity 10 to facilitate the assembly connection of the quick connector 13 on the side wall 11 of the cavity 10. The cavity 10 and the cover 20 are both rotating bodies to facilitate the manufacture of the cavity 10 and the cover 20.

[0033] like Figure 1 As shown, as an example, the centrifugal container 100 for solution stratification of the present invention further includes a fourth clamp 90c, and a convex shoulder 15 that is covered with the cover 20 is protruded from the side wall 11 of the cavity 10, and the convex shoulder 15 is located above the quick connector 13; the fourth clamp 90c holds the cover 20 and the shoulder 15 tightly from the outside, and a sealing ring 16 is sandwiched between the cover 20 and the shoulder 15, which improves the convenience of assembly and disassembly between the cover 20 and the cavity 10 on the one hand, and improves the reliability of the seal between the cover 20 and the cavity 10 on the other hand. Specifically, in combination with Figure 4 As an example, the fourth clamp 90c includes a screwing operation member 96 and a first arc-shaped clamping block 94 and a second arc-shaped clamping block 95 that clamp together. One end of the second arc-shaped clamping block 95 and the first arc-shaped clamping block 94 are hinged together, and the other opposite ends of the second arc-shaped clamping block 95 and the first arc-shaped clamping block 94 are each fixed with a straight line segment 97 (98) that fits side by side with each other. The screwing operation member 96 is used to lock or release the straight line segment 97 and the straight line segment 98. For example, the screwing operating member 96 can be composed of a bolt and a nut. When the screwing operating member 96 is composed of a bolt and a nut, the bolt is passed through the straight segment 97 and the straight segment 98 and then threadedly connected with the nut, so that the purpose of locking or releasing can be achieved through the relative movement between the bolt and the nut; obviously, according to actual needs, the screwing operating member 96 is a screw threadedly inserted into the straight segment 97, and correspondingly, a threaded hole is opened on the straight segment 98, and the purpose of locking can be achieved by threading the screw with the threaded hole, so it is not necessary to use Figure 4 It is additionally noted that the structures of the first clamp 60, the second clamp 70 and the third clamp 80 can be made the same as the structure of the fourth clamp 90c.

[0034] Compared with the prior art, with the help of the first clamp 60, the second clamp 70 and the third clamp 80, the first valve 30 and the quick connector 13 are connected quickly and tightly sealed, the blind cover 50 and the second end 142 of the three-way pipe 14 are connected quickly and tightly sealed, and the second valve 40 and the third end 143 of the three-way pipe 14 are connected quickly and tightly sealed. It is also convenient to pull out or push in the plunger 90a through the blind cover 50; at the same time, when separating the three-phase materials containing water, organic ester and solid, the first valve 30 releases water and the second valve 40 releases organic ester. More importantly, by means of the design that "the plunger 90a is fittedly placed in the first end 141 and the second end 142 of the tee pipe 14, the first end 91 of the plunger 90a also protrudes 0.2 mm to 2 mm relative to the side wall 11 of the cavity 10 in the direction of extending into the internal space 12 of the cavity 10, and the opposite second end 92 of the plunger 90a is assembled and connected with the blind cover 50", solids in the material can be prevented from entering the interior of the tee pipe 14 and the interior of the second valve 40, thereby contaminating the organic ester.

[0035] It should be noted that, as an example, the material of the cavity 10, the cover body 20, the quick connector 13, the tee pipe 14, the first valve 30, the second valve plate 40, the blind cover 50, the first clamp 60, the second clamp 70, the third clamp 80, the plunger 90a, the limiter 90b and the fourth clamp 90c can be selected to be stainless steel. Obviously, other materials well known in the art can also be selected; in addition, as an example, the blind cover 50 is fixedly connected to the second end 92 of the plunger 90a by means of a screw 51.

[0036] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
