[0002] Disc centrifuges can rapidly and continuously separate solids from liquids and liquids, a characteristic that makes them widely used in protein peptide processing. During the extraction and purification of protein peptides, disc centrifuges can effectively separate the target protein peptides from other impurities (such as unreacted raw materials, byproducts, solvents, etc.), thereby improving the purity and quality of the protein peptides. The "Novel Slag-Discharge Disc Centrifuge" disclosed in application number "CN201820685344.4" is also an increasingly mature technology.

[0007] In order to secure the connection between the electromagnetic flowmeter and the adjustable flow valve with the second bolt, the electromagnetic flowmeter, the second bolt, and the adjustable flow valve are preferably connected by a threaded connection structure, which is a preferred embodiment of this invention for a disc centrifuge with high operational flexibility.

[0008] In order to enable the connection and adjustment of the limiting cover and the base using the rotating shaft, the limiting cover, the rotating shaft and the base are preferably arranged in a rotating connection structure, which is a highly flexible disc centrifuge according to this utility model.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4. This utility model provides the following technical solution: A disc centrifuge with high operational flexibility, comprising: a centrifuge body 1, a feed pipe 2 at the top of the centrifuge body 1, a flange 3 at the opening end of the feed pipe 2, a first bolt 4 horizontally penetrating the side wall of the flange 3, a threaded connection of the first bolt 4 to an electromagnetic flowmeter 5, a second bolt 6 horizontally penetrating the surface of the inlet end of the electromagnetic flowmeter 5, a threaded connection of the second bolt 6 to an adjustable flow valve 7, a limiting cover 8 sleeved on the top of the horizontal end of the electromagnetic flowmeter 5, a rotating shaft 9 rotatably connected to one side of the limiting cover 8, a base 10 rotatably connected to the surface of the rotating shaft 9, and a third bolt 11 threadedly connected to the top of the horizontal plate on one side of the base 10. 1. A threaded connection is made to the limiting cover 8 on one side of the horizontal plate. The bottom support 10 is fixedly connected to the support frame 12. The bottom side wall of the support frame 12 is transversely connected to the fourth bolt 13. The side wall of the fourth bolt 13 is threadedly connected to both sides of the base of the centrifuge body 1. In this design, the centrifuge body 1 and the feed pipe 2 form the main body of the disc centrifuge. A large number of related components are set in the main body of the disc centrifuge. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution. In this design, the electromagnetic flowmeter 5 is existing technology. Its model is: PS4000 series electromagnetic flowmeter. When measuring the flow rate, the fluid flows through a magnetic field perpendicular to the flow direction. The flow of conductive liquid induces a voltage signal that is proportional to the average flow velocity (i.e., volumetric flow rate). Its induced voltage signal is detected by two electrodes that are in direct contact with the liquid and transmitted to the amplifier via a cable, and then converted into a current output signal. Meanwhile, the adjustable flow valve 7 is also existing technology. Its model is: manual adjustable throttle valve, which can adjust the opening size of the valve port according to the manual turntable on the top, thereby controlling the liquid inflow.

[0022] The main model of the disc centrifuge in this solution is: DHC-300 disc centrifuge;

[0023] In operation: When the protein peptide suspension (or emulsion) is added to the disc centrifuge through the feed pipe 2 located at the top center of the drum, the liquid flows through the gaps between the discs. Under centrifugal force, denser solid particles (or droplets) settle onto the discs to form sediment (or a liquid layer), then slide along the disc surface and accumulate at the largest diameter part inside the drum. The less dense liquid, propelled by subsequent liquid flow, moves along the disc channels towards the rotor center, then rises along the central axis and is discharged from the sleeve, thus achieving separation.

[0024] Preferably, the feed pipe 2, flange 3, first bolt 4 and electromagnetic flowmeter 5 form a threaded connection structure.

[0025] In actual use, the flange 3 and the first bolt 4 on the other side of the feed pipe 2 are used to fix the position of the electromagnetic flowmeter 5.

[0026] Preferably, the magnetic flowmeter 5, the second bolt 6, and the adjustable flow valve 7 form a threaded connection structure.

[0027] In practical use, the other open end of the electromagnetic flowmeter 5 is fixed to the position of the adjustable flow valve 7 by the second bolt 6. The feed port at the bottom of the adjustable flow valve 7 can be connected to the transmission pipeline of the protein peptide processing line by means of fixing bolts and other components.

[0028] Preferably, the limiting cover 8, the rotating shaft 9 and the base 10 form a rotating connection structure. The limiting cover 8 and the base 10 are both semi-circular structures, and the circular through groove formed at the intersection of the limiting cover 8 and the base 10 is adapted to the lateral end of the electromagnetic flowmeter 5.

[0029] In practical use, the limiting cover 8 and the base 10, which are sleeved on the surface of the electromagnetic flowmeter 5, are rotated and sleeved on the transverse end surface of the electromagnetic flowmeter 5 with the cooperation of the rotating shaft 9.

[0030] Preferably, the limiting cover 8, the bottom support 10, and the third bolt 11 form a threaded connection structure.

[0031] In practical use, the third bolt 11 is used to fix the position of the limit cover 8 and the base 10, thereby using the support frame 12 connected to the bottom of the base 10 to support and fix the position of the electromagnetic flowmeter 5.

[0032] Preferably, the centrifuge body 1, the support frame 12, and the fourth bolt 13 form a threaded connection structure.

[0033] In actual use, the fixing plates on both sides of the bottom of the support frame 12 abut against the two ends of the base of the centrifuge body 1, thereby fixing the position of the support frame 12 with the fourth bolt 13.

[0034] Working principle: During the protein peptide processing, the protein peptide is fed into the centrifuge body 1 via the feed pipe 2 at the top and then centrifuged. The flange 3 on the other side of the feed pipe 2 and the first bolt 4 work together to fix the position of the electromagnetic flowmeter 5. Simultaneously, the limiting cover 8 and the base 10, fitted onto the surface of the electromagnetic flowmeter 5, rotate and fit onto the transverse end surface of the electromagnetic flowmeter 5 with the help of the rotating shaft 9. The third bolt 11 is used to fix the position of the limiting cover 8 and the base 10. The support frame 12 connected to the bottom of the base 10 then supports and fixes the position of the electromagnetic flowmeter 5. At this time, the fixing discs on both sides of the bottom of the support frame 12 abut against... The electromagnetic flowmeter 5 is attached to both ends of the centrifuge body 1 base, and the position of the support frame 12 is fixed by the fourth bolt 13. In addition, the position of the adjustable flow valve 7 is fixed by the second bolt 6 at the other open end of the electromagnetic flowmeter 5. The feed port at the bottom of the adjustable flow valve 7 can be connected to the transmission pipeline of the protein peptide processing line by means of fixing bolts and other components. The feed rate of the protein peptide is adjusted by the adjustment plate at the top of the adjustable flow valve 7. At the same time, the flow rate of the protein peptide passing through the electromagnetic flowmeter 5 is monitored and displayed, so that the feed rate of the protein peptide can be flexibly adjusted according to the processing requirements to avoid equipment damage or product quality degradation caused by overload or underload.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
