Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical production equipment, and more particularly to a sample loading processing device for a chromatography system. Background Art

[0002] Chromatography systems are widely used in the fields of biology and biopharmaceuticals. They are important application equipment for purification of proteins and peptides, separation and purification of biological molecules, and production and research and development of biopharmaceuticals. The sample liquid used in the chromatography system is a suspension with a high content of polysaccharides and proteins. There are obvious bubbles in the sample liquid. The large number of bubbles in the sample liquid will affect the chromatography operation. Therefore, how to remove the bubbles in the sample liquid before loading is an urgent problem to be solved. The temperature and uniformity of the sample liquid also need to be controlled during the sample liquid loading process. These are also difficult problems that need to be solved urgently. The sample liquid used in the chromatography system is also of high value. Due to the lack of special loading equipment for loading, there are still problems such as large amount of sample liquid residue and large loss during the loading operation. The above problems urgently need to be solved by designing a special sample liquid loading and processing equipment. This case was born from this. Summary of the Invention

[0009] Furthermore, the sample liquid processor is made of heat-conducting material, and the outer wall of the sample liquid processor fits the inner cavity of the heating seat.

[0010] Furthermore, a defoaming layer is fixedly installed in the inner cavity of the sample liquid processor. The defoaming layer is made of a grid screen, and a gap is left between the defoaming layer and the inner wall of the sample liquid processor.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 4The sample processing device of a chromatography system shown in the figure is connected to the inlet front end of the chromatography system, and includes a box body 1, a sample liquid processor 3 and a power mechanism 5. A heating seat 2 is fixedly installed in the box body 1, and the sample liquid processor 3 is rotatably installed in the heating seat 2. The sample liquid processor 3 is in the shape of a conical funnel, and the top of the sample liquid processor 3 is open. The top diameter of the sample liquid processor 3 is larger than the bottom diameter. A liquid inlet 11 is provided on the top of the box body 1, and the sample liquid is input from the liquid inlet 11. The liquid inlet 11 is connected to an infusion tube 111, and the infusion tube 111 extends downward to the top open position of the sample liquid processor 3. The input sample liquid is guided by the infusion tube 111 and is contained in the sample liquid processor 3, and then is processed. The heating seat 2 provides the required temperature for the sample liquid, and the sample liquid processor 3 can be relatively The heating seat 2 rotates, and an auxiliary stirring mechanism 4 is installed at the bottom of the sample liquid processor 3. The power mechanism 5 is transmission-connected to the sample liquid processor 3 and the auxiliary stirring mechanism 4. The power mechanism 5 can drive the sample liquid processor 3 and the auxiliary stirring mechanism 4 to rotate synchronously. The rotation of the sample liquid processor 3 can stir the sample liquid and remove bubbles in the sample liquid. The liquid is discharged from the bottom of the sample liquid processor 3. The auxiliary stirring mechanism 4 is also installed at the bottom of the sample liquid processor 3, which can form a stirring effect on the output sample liquid to ensure its uniformity. A liquid outlet 13 is provided on the side wall of the box 1, and a pipeline is connected to the liquid outlet 13 at the bottom of the sample liquid processor 3. The liquid outlet 13 is the final liquid outlet position of the present invention. The pipeline of the liquid outlet 13 is connected to the inlet of the chromatography system. The sample liquid output through the present invention has the advantages of few bubbles and good uniformity.

[0024] like Figure 2 and Figure 3 As shown, the auxiliary stirring mechanism 4 includes a rotating shaft 41, which is upright and rotatably installed at the bottom of the sample liquid processor 3. The top of the rotating shaft 41 is inserted into the sample liquid processor 3, and a stirring blade 42 is installed on the outer wall of the inserted part of the rotating shaft 41. When the rotating shaft 41 rotates, the stirring blade 42 can form a stirring effect on the sample liquid at the bottom of the sample liquid processor 3. The stirring effect directly acts on the sample liquid output position, which can ensure the uniformity of the output sample liquid.

[0025] like Figure 3 As shown, a liquid outlet channel 411 is provided in the rotating shaft 41, and a plurality of liquid outlet holes 412 are provided on the outer wall of the inserted portion of the rotating shaft 41. The liquid outlet holes 412 are connected to the liquid outlet channel 411. The present invention cleverly uses the rotating shaft 41 as an output pipe. The rotating shaft 41 can be used as a stirring mechanism and can meet the needs of outputting sample liquid. A rotary joint is installed at the bottom of the liquid outlet channel 411 (i.e., the bottom of the rotating shaft 41), and then the pipeline is connected to the liquid outlet 13 to meet the output of the sample liquid. A first control valve 131 is installed on the connecting pipeline from the liquid outlet channel 411 to the liquid outlet 13. The first control valve 131 can control the opening and closing of the connecting pipeline from the liquid outlet channel 411 to the liquid outlet 13. Figure 2As shown, the heating seat 2 and the sample liquid processor 3 are installed in the middle section of the box body 1, and a waste liquid area 14 is provided at the bottom of the box body 1. The bottom of the liquid outlet channel 411 is also connected to the waste liquid area 14 by a pipeline. A second control valve 141 is installed on the connecting pipeline between the liquid outlet channel 411 and the waste liquid area 14. The second control valve 141 can control the opening and closing of the connecting pipeline between the liquid outlet channel 411 and the waste liquid area 14. The first control valve 131 and the second control valve 141 are not opened at the same time, that is, the two liquid outlets cannot be opened at the same time. In actual use, they are either closed at the same time or opened alternately. During the liquid discharge operation, the first control valve 131 is generally opened first, and the sample liquid is output from the liquid outlet 13. As the sample liquid gradually flows out to a small amount at the bottom, the first control valve 131 is closed and the second control valve 141 is opened to allow the residual liquid at the bottom to flow to the waste liquid area 14 (the final residual liquid at the bottom generally has a large bubble content, so it is discarded).

[0026] like Figure 2 As shown, the power mechanism 5 includes a motor 51, a first transmission bevel gear 53 and a second transmission bevel gear 54. The motor 51 is fixedly installed in the box body 1. The output end of the motor 51 is installed with a driving bevel gear 52. The first transmission bevel gear 53 is fixedly installed at the bottom of the sample liquid processor 3. The second transmission bevel gear 54 is fixedly installed on the outer wall of the rotating shaft 41 (a bracket of the rotating shaft 41 is installed in the box body 1, and the rotating shaft 41 is also rotatably installed on the bracket). The first transmission bevel gear 53 and the second transmission bevel gear 54 are symmetrically installed. The first transmission bevel gear 53 and the second transmission bevel gear 54 are meshed with the driving bevel gear 52. The driving bevel gear 52 can drive the first transmission bevel gear The wheel 53 and the second transmission bevel gear 54 rotate synchronously in opposite directions. Since the rotation directions of the first transmission bevel gear 53 and the second transmission bevel gear 54 are opposite, the sample liquid processor 3 and the auxiliary stirring mechanism 4 can form a synchronous opposite direction movement effect. Such a reverse movement effect is conducive to the stirring of the sample liquid, enhances the bubble removal effect and enhances the uniformity guarantee effect. The sample liquid processor 3 is made of heat-conducting material. The outer wall of the sample liquid processor 3 fits into the inner cavity of the heating seat 2. The heating seat 2 can be heated by electricity or heat-conducting oil. The heat of the heating seat 2 can be transferred to the sample liquid processor 3, forming a heating effect on the sample liquid inside to meet the temperature requirement of the loading sample liquid.

[0027] The bubbles in the sample liquid can be effectively removed by the rotation and stirring of the sample liquid processor 3, but the removal effect can be further improved. Figure 2 and Figure 3 As shown, the present invention also has a defoaming layer 31 fixedly installed in the inner cavity of the sample liquid processor 3, as shown in FIG. Figure 4As shown, the defoaming layer 31 is made of a grid screen, and the defoaming layer 31 has mesh holes. There is a gap between the defoaming layer 31 and the inner wall of the sample liquid processor 3. In the process of the sample liquid processor 3 rotating and stirring the sample liquid, the sample liquid will continue to flow inside and outside the defoaming layer 31, and the mesh holes of the defoaming layer 31 can break the bubbles in the sample liquid, which can further improve the defoaming quality. The sample liquid processor 3 and the auxiliary stirring mechanism 4 of the present invention need to rotate at a low and uniform speed to meet the processing requirements. Since the sample liquid processor 3 can rotate, the sample liquid residual on the wall will have a tendency to fall centrifugally, which helps to reduce wall residue and reduce operating losses.

[0028] like Figure 2 As shown, a monitoring area 12 is provided on the top of the box body 1, and a temperature measuring element 121 and a liquid level monitor 122 are installed in the monitoring area 12. The temperature measuring element 121 monitors the temperature changes in the box body 1 in real time to control the liquid temperature of the sample liquid. The liquid level monitor 122 is installed with a downward extending probe 1221. The probe 1221 extends into the cavity of the sample liquid processor 3. The liquid level monitor 122 detects the highest liquid level of the sample liquid poured into the sample liquid processor 3 to prevent overflow due to excessive sample liquid being poured in.

[0029] After each shift, the sample liquid processor 3 needs to be cleaned to keep it clean. Figure 2 As shown, an annular fixing seat 15 is installed in the box body 1, and the fixing seat 15 is located between the monitoring area 12 and the sample liquid processor 3. A number of spray nozzles 151 are evenly distributed along the annular length direction of the fixing seat 15. The spray nozzles 151 are arranged facing the inner wall of the sample liquid processor 3. A water storage area 16 is provided at the bottom of the box body 1. The water storage area 16 stores cleaning water. The water storage area 16 is connected to the spray nozzle 151 through a pipeline. During the cleaning operation, water is supplied to the spray nozzle 151 through a water pump. The wash nozzle 151 sprays water onto the inner wall of the sample liquid processor 3. As the sample liquid processor 3 rotates, the inner wall of the sample liquid processor 3 can be completely rinsed. During the flushing operation, the second control valve 141 is opened and the first control valve 131 is closed, and the cleaning waste water flows to the waste liquid area 14. An ultraviolet lamp 123 is installed directly above the sample liquid processor 3. After the flushing is completed, the ultraviolet lamp 123 is turned on for drying and disinfection. The ultraviolet lamp 123 is not turned on during the normal sample liquid processing stage.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
