The high-pressure cylinder is in flow connection with the output end of the high-pressure one-way valve, so that a part of materials input into the high-pressure one-way valve by the feeding source can enter the high-pressure cylinder; and the driving mechanism is in transmission connection with a plunger rod, and the driving mechanism is used for driving the plunger rod to extend into the high-pressure cylinder to extrude the materials so as to pressurize the materials.

Description

Technical Field

[0001] This utility model belongs to the technical field of material compression, and in particular relates to an ultra-high pressure booster structure. Background Technology

[0002] Both high-pressure sterilization and high-pressure microjet technology apply extremely high pressure (300MPa-400MPa) to materials to physically destroy or alter their structure, thereby processing the materials to a specific state (such as sterilization or crushing).

[0003] An ultra-high pressure booster is a device used to increase the pressure of fluids (liquid or gas) to ultra-high pressure ranges (usually above 100 MPa, and even up to 1000 MPa). It is widely used in fields such as high-pressure sterilization technology and high-pressure microjet technology. Its core structural design must take into account pressure resistance, sealing and reliability.

[0004] Traditional ultra-high pressure boosters cannot adjust their output pressure themselves; they need to adjust the pressure of the externally input material to achieve boosting. Therefore, the interface between the compressed and uncompressed material changes dynamically with the pressure of the externally input material, making it difficult to accurately and stably control the pressure of the material during the processing (pressurization process). Utility Model Content

[0005] The purpose of this invention is to provide an ultra-high pressure booster structure to solve the technical problems described in the background art.

[0006] The structure of the ultra-high pressure booster includes:

[0007] A high-pressure check valve, wherein the input end of the high-pressure check valve is connected to a material supply source, and the material in the material supply source can only flow into the high-pressure check valve in one direction.

[0008] A high-pressure cylinder is flow-connected to the output end of the high-pressure check valve, so that a portion of the material input from the feed source to the high-pressure check valve can enter the high-pressure cylinder.

[0009] A drive mechanism is provided, which is connected to a plunger rod. The drive mechanism is used to drive the plunger rod to extend into the high-pressure cylinder to compress the material and thus pressurize it.

[0010] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0011] When pressure is applied to the material, the feed source inputs the material from the input end of the high-pressure check valve. At this time, the material enters the high-pressure cylinder through the high-pressure check valve and fills the high-pressure cylinder. Subsequently, when the feed source inputs material into the high-pressure check valve so that the material after entering the high-pressure check valve reaches a pressure value close to the set value, the drive mechanism drives the plunger rod to extend into the high-pressure cylinder. At this time, the plunger rod pressurizes the material in the high-pressure cylinder. Since the output end of the high-pressure check valve and the high-pressure cylinder are connected, the pressure of the material entering the high-pressure check valve is also pressurized to the set pressure. During the pressurization of the material in the high-pressure cylinder by the plunger rod, the material in the feed source can only flow into the high-pressure check valve in one direction, and the material cannot flow back to the feed source due to excessive pressure.

[0012] In summary, the ultra-high pressure booster structure described in this utility model, compared with traditional ultra-high pressure boosters, can accurately and stably apply pressure to the input material after it is fed from the material source. At the same time, during the material feeding process, the pressure will not be unstable due to the dynamic changes in the interface between the compressed and uncompressed materials caused by the pressure of the external input material.

[0013] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0014] In some embodiments, the drive mechanism includes:

[0015] A hydraulic cylinder, wherein hydraulic oil inlets and outlets are provided at both ends of the hydraulic cylinder, and a movable piston is provided between the two hydraulic oil inlets and outlets, and the piston is connected to the plunger rod;

[0016] An oil pump is connected to the hydraulic oil inlet and outlet. The oil pump is used to supply or extract hydraulic oil to the hydraulic oil inlet and outlet at both ends, so as to push the piston and drive the plunger rod to extend into the high-pressure cylinder to squeeze the material.

[0017] Based on the above technical solution, the oil pump delivers or extracts hydraulic oil through the hydraulic oil inlet and outlet at both ends, pushing the piston to move the piston rod, thereby achieving precise adjustment of the material pressure in the high-pressure cylinder.

[0018] In some embodiments, inductive sensors for sensing the position of the piston are provided next to the hydraulic oil inlet and outlet at both ends.

[0019] Based on the above technical solution, the piston position is sensed by an inductive sensor to monitor the movement stroke of the plunger rod, thereby enabling real-time monitoring and adjustment of the plunger rod to pressurize the material in the high-pressure cylinder, thus improving the stability and accuracy of the system.

[0020] In some embodiments, the high-pressure check valve is further provided with another output terminal, which can only output in one direction and is used to connect to a material storage chamber or a material back-end processing mechanism.

[0021] Based on the aforementioned technical solution, the piston rod can be driven by the drive mechanism to reciprocate into the high-pressure cylinder to squeeze the material, thereby continuously generating high pressure for the material in the material storage chamber or at the rear end of the material, as well as for the material newly fed in from the input end of the high-pressure one-way valve, ensuring the efficient operation of the system.

[0022] In some embodiments, the material storage chamber or the material back-end processing mechanism is equipped with a safety valve;

[0023] Based on the aforementioned technical solution, when the pressure of the material fed into the input end of the high-pressure check valve exceeds the set value, the pressure can be automatically released through the safety valve, thereby protecting the equipment and ensuring operational safety.

[0024] In some embodiments, an ultra-high pressure booster structure further includes:

[0025] A pressure sensor is used to monitor the material pressure in the material storage chamber or the material downstream processing mechanism.

[0026] The control system is electrically connected to the drive mechanism, the inductive sensor, the safety valve, and the pressure sensor. The control system is used to control the operation of the drive mechanism according to the material pressure sensed by the pressure sensor.

[0027] Based on the above technical solution, the control system controls the material flow and pressure fed into the high-pressure check valve by the material supply source, and at the same time controls the stroke of the piston rod by the drive mechanism, so that the material supply source and the drive mechanism work together to achieve efficient adjustment and control of the working parameters when pressurizing the material.

[0040] The following is a description of the operation of an ultra-high pressure booster structure as described in this embodiment.

[0041] When pressure is applied to the material, the feed source 2 inputs the material from the input end 11 of the high-pressure check valve 1. At this time, the material enters the high-pressure cylinder 3 through the high-pressure check valve 1 and fills the high-pressure cylinder 3. Subsequently, when the feed source 2 inputs material into the high-pressure check valve 1 so that the material after entering the high-pressure check valve 1 reaches a pressure value close to the set value, the drive mechanism 4 drives the plunger rod 5 to extend into the high-pressure cylinder 3. At this time, the oil pump delivers or extracts hydraulic oil through the hydraulic oil inlet and outlet 42 at both ends, pushing the piston 51 to drive the plunger rod to move. The plunger rod 5 will pressurize the material in the high-pressure cylinder 3. Since the output end 12 of the high-pressure check valve 1 and the high-pressure cylinder 3, that is, the material entering the high-pressure check valve 1, are also pressurized to the set pressure. During the pressurization of the material in the high-pressure cylinder 3 by the plunger rod 5, since the material in the feed source 2 can only flow into the high-pressure check valve 1 in one direction, the material cannot flow back to the feed source 2 due to excessive pressure. Example

[0042] like Figures 1 to 4 As shown, this embodiment provides an ultra-high pressure booster structure, which includes a high-pressure one-way valve 1, a high-pressure cylinder 3, a drive mechanism 4, a pressure sensor 7, and a control system 8.

[0043] The input end 11 of the high-pressure one-way valve 1 is connected to the material supply source 2, and the material in the material supply source 2 can only flow into the high-pressure one-way valve 1 in one direction.

[0044] The high-pressure cylinder 3 is flow-connected to the output end 12 of the high-pressure one-way valve 1, so that a portion of the material input from the feed source 2 to the high-pressure one-way valve 1 can enter the high-pressure cylinder 3.

[0045] The drive mechanism 4 is connected to a plunger rod 5. The drive mechanism 4 is used to drive the plunger rod 5 into the high-pressure cylinder 3 to compress the material, thereby pressurizing the material. The drive mechanism 4 includes a hydraulic cylinder 41 and an oil pump. The hydraulic cylinder 41 has hydraulic oil inlets and outlets 42 at both ends. A movable piston 51 is arranged between the hydraulic oil inlets and outlets 42 at both ends. An inductive sensor 43 for sensing the position of the piston 51 is arranged next to the hydraulic oil inlets and outlets 42 at both ends. The piston 51 is connected to the plunger rod 5. The oil pump is connected to the hydraulic oil inlets and outlets 42. The oil pump is used to supply or extract hydraulic oil to the hydraulic oil inlets and outlets 42 at both ends to push the piston 51 and drive the plunger rod 5 into the high-pressure cylinder 3 to compress the material.

[0046] The high-pressure one-way valve 1 is also provided with another output terminal 13, which can only output in one direction. The other output terminal 13 is used to connect to the material storage chamber or the material back-end processing mechanism. Both the material storage chamber and the material back-end processing mechanism are provided with safety valves 6.

[0047] Pressure sensor 7 is used to monitor the material pressure in the material storage chamber or the material processing mechanism at the rear end; control system 8 is electrically connected to the drive mechanism 4, the inductive sensor 43, the safety valve 6 and the pressure sensor 7, and the control system 8 is used to control the drive mechanism 4 to work according to the material pressure sensed by the pressure sensor 7.

[0048] The following is a description of the operation of an ultra-high pressure booster structure as described in this embodiment.

[0049] When pressure is applied to the material, the material supply source 2 inputs the material from the input end 11 of the high-pressure check valve 1. At this time, the material enters the high-pressure cylinder 3 through the high-pressure check valve 1 and fills the high-pressure cylinder 3 and the material storage chamber or the material rear processing mechanism. Subsequently, when the material supply source 2 inputs material into the high-pressure check valve 1 so that the material after entering the high-pressure check valve 1 reaches a pressure value close to the set value, the drive mechanism 4 drives the plunger rod 5 to extend into the high-pressure cylinder 3. At this time, the oil pump delivers or extracts hydraulic oil through the hydraulic oil inlet and outlet 42 at both ends, pushing the piston 51 to drive the plunger rod to move. The plunger rod 5 will pressurize the material in the high-pressure cylinder 3. Since the output end 12 of the high-pressure check valve 1 and the high-pressure cylinder 3, that is, the material entering the high-pressure check valve 1, are also pressurized to the set pressure. During the pressurization of the material in the high-pressure cylinder 3 by the plunger rod 5, since the material in the material supply source 2 can only flow into the high-pressure check valve 1 in one direction, the material cannot flow back to the material supply source 2 due to excessive pressure. Furthermore, the driving mechanism 4 drives the plunger rod 5 to reciprocate into the high-pressure cylinder 3 to compress the material, thereby continuously generating high pressure on the material in the material storage chamber or at the rear end of the material, as well as on the material newly fed from the input end 11 of the high-pressure check valve 1. Furthermore, the control system 8 controls the flow rate and pressure of the material fed from the feed source 2 into the high-pressure check valve 1, and simultaneously controls the stroke of the plunger rod 5 driven by the driving mechanism 4, so that the feed source 2 and the driving mechanism 4 work in coordination, thereby achieving efficient adjustment and control of the working parameters when pressurizing the material.
