The suction valve ear 20 and the discharge valve ear 21 are respectively installed on the suction port 27 and the discharge port 28. When the piston 19 moves away from the partition 23, the suction valve ear 20 opens the suction port 27 and the discharge valve ear 21 closes the discharge port 28. When the piston 19 moves toward the partition 23, the suction valve ear 20 closes the suction port 27 and the discharge valve ear 21 opens the discharge port 28. The piston 19 structure is used to realize multiphase flow, that is, efficient and continuous transportation of gas, solid and liquid mixtures, which overcomes the extreme requirements of gas, solid and liquid mixtures on pumps and valves.

[0038] As attached Figure 1 and attached Figure 2 As shown, the suction valve ear 20 includes a suction valve stem 29 matched with the transmission mechanism 7, a suction valve disc 30 arranged on the suction valve stem 29, and a first elastic member 31 for driving the suction valve stem 29 and the suction valve disc 30 to reset; the discharge valve ear 21 includes a discharge valve stem 32 matched with the transmission mechanism 7, a discharge valve disc 33 arranged on the discharge valve stem 32, and a second elastic member 34 for driving the discharge valve stem 32 and the discharge valve disc 33 to reset, wherein the suction valve disc 30 and the discharge valve disc 33 both have a first conical sealing surface, the suction port 27 and the discharge port 28 both have a second conical sealing surface, the first elastic member 31 and the second elastic member 34 can be springs, one end of the first elastic member 31 is relatively fixed and can be fixedly connected to the cylinder body 18, and the other end is fixedly connected to the suction valve disc 30 or the suction valve stem 29, and the second elastic member 34 is the same.

[0039] As attached Figure 1 and attached Figure 2As shown, the transmission mechanism 7 includes a driving crankshaft 35 and a driven crankshaft 36, which are rotatably arranged on the pump body 4, and the driving crankshaft 35 and the driven crankshaft 36 are linked by a transmission member 37. The variable frequency motor 5 is linked with the driving crankshaft 35 to drive the driving crankshaft 35 to rotate. The driving crankshaft 35 is axially provided with a plurality of main shaft cams 38, and the directions of each adjacent two main shaft cams 38 are opposite. In this embodiment, they are arranged on the left and right. The main shaft cams 38 are connected to the corresponding piston rod 26 to push and pull the piston 19 for axial displacement along the cylinder body 18. The driven crankshaft 36 is axially provided with a plurality of slave shaft cams 39, and the directions of each adjacent two slave shaft cams 39 are opposite. In this embodiment, they are arranged on the left and right. The suction valve stem 29 and the discharge valve stem 32 are respectively matched with the two adjacent slave shaft cams 39. The driving crankshaft 35 and the driven crankshaft 36 are connected by a transmission member 37, that is, when the variable frequency motor 5 drives the driving crankshaft 35 to rotate, the driven crankshaft 36 rotates at the same time, so that the piston 19 moves, and the corresponding suction valve ear 20 and discharge valve ear 21 are opened and closed. Only one variable frequency motor 5 is needed to realize the linkage of multiple structures, which not only has lower cost but also better structural stability.

[0040] More specifically, the transmission member 37 is a gear transmission assembly, a chain transmission assembly, or a belt transmission assembly.

These are multiple settings of the transmission member 37, which can realize the linkage of the driving crankshaft 35 and the driven crankshaft 36.

[0041] The outer circumferential surface of the piston 19 is provided with a sealing ring for sealing with the inner circumferential surface of the cylinder body 18. The sealing between the two can be achieved to prevent the medium from leaking from the gap between the two.

[0042] As attached Figure 1 As shown, a first check valve 40 is provided at the inlet 13 of the pump body 4, which only allows the medium to enter the pump body 4, and a second check valve 41 is provided at the outlet 14 of the pump body 4, which only allows the medium to be discharged from the outside of the pump body 4. The first check valve 40 and the second check valve 41 not only prevent backflow, but also have the effects of reducing noise and breaking tail flow.

[0043] As attached Figure 1As shown, a lubricating oil groove 42 for delivering lubricating oil to each lubricating point is provided in the pump body 4. By delivering lubricating oil to each lubricating point through the oil pump, each transmission component in the pump body 4 can be accurately lubricated, reducing component wear and extending the overall service life.

[0044] As an extended solution, multiple continuous suction units 8 are all arranged on the same side of the active crankshaft 35 and are evenly distributed along the axial direction of the active crankshaft 35. This is the first arrangement of the continuous suction units 8, which has the advantage of efficient transmission.

[0045] As a further expansion scheme, multiple continuous suction units 8 are arranged on both sides of the active crankshaft 35, and the continuous suction units 8 on both sides are evenly distributed along the axial direction of the active crankshaft 35. In this scheme, the corresponding piston rods 26 on both sides can share a rod or two separate rods, and in this scheme, one active crankshaft 35 drives and two driven crankshafts 36 transmit. This is the second setting mode of the continuous suction unit 8, which can further improve the mixed transmission efficiency.

[0046] As attached Figure 1 As shown, the separation, boosting and mixing tank 2 is provided with a porous baffle 43 at the position corresponding to the inner end of each second pipe 16, and a feed port 44 is provided at the bottom of the porous baffle 43. This design can not only achieve a decompression effect, but also prevent the medium from impacting the inner wall of the tank body, thereby protecting the separation, boosting and mixing tank 2 and reducing noise.

[0047] As attached Figure 1 As shown, the suction tank 1 is provided with a suction level sensor interface 45 and a suction pressure frequency conversion sensor interface 46, and the suction level sensor interface 45 and the suction pressure frequency conversion sensor interface 46 are respectively installed with a first liquid level sensor 47 and a first pressure frequency conversion sensor 48; the separation and pressurization mixing tank 2 is provided with a mixed liquid level sensor interface 49 and a mixed pressure frequency conversion sensor interface 50, and the mixed liquid level sensor interface 49 and the mixed pressure frequency conversion sensor interface 50 are respectively installed with a second liquid level sensor 51 and a second pressure frequency conversion sensor 52; the cylinder body 18 is provided with a detection element 53, which can be a temperature and pressure sensor and a flow sensor, and the first liquid level sensor 47, the first pressure frequency conversion sensor 48, the second liquid level sensor 51, the second pressure frequency conversion sensor 52, and the detection element 53 are all electrically connected to the intelligent control cabinet 3 through wires. The sensors are arranged to obtain important internal data information (such as pressure, liquid level, temperature, etc.) of the suction tank 1, the separation and pressurization mixing tank 2 and the cylinder body 18 in real time, so that the intelligent control cabinet 3 can control the working state of the variable frequency motor 5 (such as start and stop, speed, etc.) in real time and accurately.

[0048] As attached Figure 1As shown, the suction tank 1 is provided with a suction safety valve interface 54, and the suction safety valve interface 54 is connected to a first safety valve 55. The separation and pressurization mixed tank 2 is provided with a mixed safety valve interface 56, and the mixed safety valve interface 56 is connected to a second safety valve 57. The first safety valve 55 and the second safety valve 57 are both conventional parts available on the market, so their specific structures are not described in detail here. Safety valve structures are set on both the suction tank 1 and the separation and pressurization mixed tank 2. When the internal pressure of any tank is too high, the corresponding safety valve can be used to release the pressure to avoid the occurrence of safety accidents.

[0049] Working principle: During the suction operation, the data signals of each sensor are transmitted to the intelligent control cabinet 3, and the intelligent control cabinet 3 controls the start and stop and the speed of the variable frequency motor 5. The variable frequency motor 5 drives the active crankshaft 35 to rotate, and the active crankshaft 35 drives the driven crankshaft 36 to rotate through the transmission member 37. The main shaft cam 38 on the active crankshaft 35 cooperates with the corresponding piston rod 26, and the driven crankshaft 36 cooperates with the corresponding suction valve ear 20 or the discharge valve ear 21; taking a group of continuous suction units 8 as an example, the piston 19 of one group of suction components 17 is pulled by the piston rod 26 of the active crankshaft 35, so that the internal space of the cylinder body 18 generates negative pressure. At the same time, the suction valve ear 20 corresponding to the piston 19 structure opens the suction port 27 under the action of the corresponding slave shaft cam 39 on the driven crankshaft 36, and the discharge valve ear 21 corresponding to the piston 19 structure closes the discharge port 28 under the action of the second elastic member 34. At this time, the suction component 17 performs the suction process. , then the piston 19 of the suction assembly 17 is pushed by the piston rod 26 of the active crankshaft 35, so that the internal space of the cylinder 18 is compressed. At the same time, the suction valve ear 20 corresponding to the piston 19 structure closes the suction port 27 under the action of the first elastic member 31, and the discharge valve ear 21 corresponding to the piston 19 structure opens the discharge port 28 under the action of the corresponding slave cam 39 on the driven crankshaft 36, realizing a suction-one-discharge action; while an adjacent group of suction assemblies 17 performs the opposite work, that is, a row-one suction action, from transporting the medium in the suction tank 1 to the separation booster mixed tank 2; the solid, liquid and gas media in the separation booster mixed tank 2 will be layered in the tank body due to different densities, and will be discharged from the gas outlet 10, the liquid outlet 11 and the solid outlet 12 respectively; similarly, it can also transport any two mixtures of gas, solid and liquid, and can also transport any single medium of gas, solid and liquid. Similarly, multiple groups of continuous suction units 8 can be set as needed to further improve the mixed transport efficiency. In addition, by switching the first check valve 40 and the second check valve 41, suction and injection can be performed.
