Description

Technical Field

[0001] The invention relates to the technical field of high-pressure delivery and metering integrated pumps, in particular to an overpressure fluid metering delivery pump. Background Art

[0002] A delivery pump is a device that continuously delivers fluid that meets the pumping conditions to a designated location through a laid pipeline.

[0003] Currently, there are many kinds of pump products that can be used for conveying or metering. However, traditional metering pumps have low fluid conveying efficiency, small conveying volume, and poor sealing conditions between chambers due to imperfect design. The conveying efficiency and metering accuracy vary greatly due to factors such as rotation speed, fluid viscosity, and temperature. There are also various shortcomings such as unstable operating performance due to wearing parts caused by mechanical friction, complex replacement and maintenance, and high conveying costs. Therefore, after research, a new design logic for overpressure fluid metering pumps was proposed to solve the above problems.

[0004] The present invention relates to an overpressure fluid metering delivery pump, which adopts a motor or a diesel engine as driving power, and is manufactured by combining a cone disk and opening and closing blades A, B, and C to form a delivery cavity with variable delivery characteristics. The delivery pump has multiple advantages such as large delivery volume, high output pressure, suitability for high-lift pump delivery, low manufacturing and maintenance costs, and convenient and flexible operation. The pump is widely used in fields such as urban water supply and drainage. Summary of the invention

[0005] (I) Technical Problem Solving and Features and Advantages

[0006] In view of the deficiencies in the prior art, the present invention provides an overpressure fluid metering delivery pump, which drives the rotating shaft through external power and drives the change in the opening and closing angle formed by the conical disk and the opening and closing blades A, B, and C inside the spherical cavity to achieve the change ratio of the delivery cavity volume to determine the delivery volume and delivery efficiency of the delivery pump, completely breaking the defect of low efficiency delivery in the fixed volume chamber formed by fixed blades, spirals, plungers, slides and media used in traditional volumetric pumps.

[0007] (II) Technical solution

[0008] The described super-pressure fluid metering delivery pump comprises a spherical cavity, wherein the spherical cavity is fixedly provided with a material input pipe outwardly as shown in the left side of the figure, and two fixed baffles with bearing holes are fixed inside the spherical cavity at a certain angle, and are respectively installed with a rotatable first rotating shaft and a second rotating shaft at positions extending from the bearing holes of the two fixed baffles to the eccentric holes opened in the spherical cavity. The two rotating shafts extend outwardly to the outside of the spherical cavity, intersect inwardly at the center point of the spherical cavity, and a synchronously rotatable conical disk is fixedly installed at the front end, and the conical surface radius of the two conical disks needs to be close to or equal to the inner wall radius of the spherical inner cavity, and the bottom surface radius needs to be equal to the large radius of the fixed baffle, and the two conical disks are connected by connecting the opening and closing hinges and the opening and closing blades A, B, and C with the arc edges facing outward to the inner wall of the spherical cavity to form a synchronously rotating linkage device, and the radius and fan-shaped curvature of the two opening and closing blades are respectively equal to the radius and curvature of the inner wall of the spherical cavity. The spherical cavity is fixedly provided with a material discharge pipe on the right side (back side) as shown in the figure, the second rotating shaft extends outward on the outer wall of the spherical cavity, and is fixedly installed with a fixing seat with a central hole through a tubular fixing bracket and bolts, and a driving motor connected to the rotating shaft to form a rotating effect is fixedly installed on the fixing seat, and a bipolar induction magnet is fixedly installed on the rotating shaft below the fixing seat and horizontally passes through the axis position, and a Hall metering sensor is fixedly installed at the bottom of the fixing seat in the area where the induction magnet can be sensed.

[0009] The conveying cavity and conveying linkage device include: a spherical inner cavity, a sealed bearing, a bearing seat, a fixed baffle, a conical disk, a rotating shaft, a connecting hinge 901, A, B, C blades connecting the opening and closing blade groups A, B, C, a fixed seat, and a driving motor.

[0010] Furthermore, the spherical cavity is divided into two upper and lower hemispherical cavities, which are connected to form a spherical inner cavity with a standard inner circle through flanges and bolts.

[0011] Furthermore, the major diameter of the fixed baffle needs to be much smaller than the diameter of the inner wall of the spherical cavity and larger than its radius. The two circular fixed baffles with central holes and sealed bearings are placed in the circular inner cavity, and are slid to the left side of the structural diagram and opened at a certain angle to form a position in which one side is adjacent and the other side is opened away from and tightly attached to the inner wall of the spherical cavity, and then fixed after the rotating shaft and the conical disk are installed.

[0012] Furthermore, as shown in the figure, different areas corresponding to the hole in the fixed baffle and the rotating shaft extending to the outside of the outer wall of the spherical cavity are respectively provided with eccentric holes for fixing the two bearing seats on the first rotating shaft and the second rotating shaft. The diameter of the eccentric hole needs to be larger than the diameter of the rotating shaft to facilitate the fixation after verifying the angle of the rotating shaft. The first rotating shaft and the second rotating shaft are respectively inserted into the appropriate corresponding positions on the fixed baffle bearing seat and the eccentric hole bearing seat, and fixed after the cone disk is installed.

[0013] Furthermore, the cone radius of the two conical disks must be close to or equal to the radius of the inner wall of the spherical inner cavity, and the bottom radius must be equal to the large radius of the fixed baffle. The cone angle vertices of the two conical disks intersect at the center of the spherical cavity as a fulcrum, and both are brought together to the left side as shown in the figure to retain only the best angle position that allows the opening and closing blades A, B, and C9 to rotate smoothly, while they are opened to the maximum angle as shown on the right side of the figure.

[0014] Furthermore, the two conical disks with an open angle are fixed to the front end position of the rotating shaft on one side of the center of the spherical cavity through the hole in the bottom surface, and the two cone angle vertices are kept inward and intersecting at the center point of the spherical cavity. The bottom of the two conical disks and the fixed baffle must be in a parallel and close angular position.

[0015] Furthermore, the cone angle between the two cone disks fixed with the rotating shaft is adjusted respectively to reach the optimal rotation and opening and closing conveying angle, and then the edges of the two fixed baffles and the eccentric hole bearing seat are fixed to different positions corresponding to the spherical cavity respectively, so that when the rotating shaft drives the cone disk to rotate, the corresponding cone surface positions between the cone disks form the basic conditions for spatially varying conveying effects.

[0016] Furthermore, the two cone disks are both located between the two fixed baffles, and the material input pipe and the material discharge pipe are both located in the inner area between the two rotating cone disks but correspond to two positions on different sides.

[0017] Furthermore, the three groups of conveying opening and closing blades A, B, and C are respectively connected by connecting opening and closing hinges at the middle opening and closing positions, and the radius and outer fan-shaped curvature of each of the three groups of conveying opening and closing blades A, B, and C are close to or the same as the radius and curvature of the inner wall of the spherical cavity (1), so as to achieve a flexible opening and closing conveying effect during the process of rotation, opening and closing movement.

[0018] Furthermore, the conical surfaces of the two conical disks are respectively divided into three equal angles in a radial manner, with the arc-shaped side surfaces of the three groups of opening and closing blades A, B, and C being outwardly attached to the inner wall of the spherical cavity. The two side edges of each group of opening and closing blades are respectively connected to the two conical disks by connecting the opening and closing hinges, thereby connecting the two rotating shafts and the conical disks into a whole that rotates synchronously, and has the structural characteristics of being divided into three independent small chambers for conveying materials in combination with the inner wall of the spherical cavity.

[0019] Furthermore, the spherical cavity is located on the outer wall at a position corresponding to the second rotating shaft, and a fixing seat with a central hole for fixing the driving motor is fixedly installed through a tubular fixing bracket.

[0020] Furthermore, the driving motor corresponds to the position of the rotating shaft, and the rotor is extended and connected to the rotating shaft, thereby achieving the purpose of driving the rotating shaft to rotate, and the stator of the outer driving motor is fixed to the fixing seat by bolts.

[0021] Furthermore, the Hall metering sensor is fixed on the inner side of the tubular fixing bracket below the fixing seat corresponding to the second rotating axis and close to the bipolar magnetic block, and records the conveying volume and standard by the number of rotations.

[0022] (III) Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] 1. Because it conveys through the rotating cone disk and drives the blades A, B, and C to form a moving chamber, it achieves the purpose of conveying fluids by the movement of common opening and closing and swirling conveying. It is different from the reciprocating extrusion method such as the plunger, so there is no excessive vibration of the conveying equipment and more useless work consumption, thereby realizing a smoother and most energy-saving conveying energy conversion.

[0024] 2. Currently, propeller blades and turbines on the market use the inclined surface with different force angles to drive the fluid to rotate and achieve the power output of the pushing effect. Due to the attenuation of the force value and impact consumption, their effective utilization conversion rate is low. The transportation operation mechanism and transportation method proposed by this invention belong to the pressure transportation method formed by direct propulsion, so the transportation energy conversion utilization rate is higher.

[0025] 3. The design concept of the conveying equipment is to use the cone surface of the cone disk and the opening and closing blades A, B, and C in the spherical inner cavity to fit the inner wall of the spherical cavity to realize the rotation and movement of materials in the conveying cavity. Because the opening and closing ratio of the cone surface and the opening and closing blades is large, and the expansion and contraction ratio is high, it has a stronger and greater advantage in the conveying volume ratio in terms of the conveying and metering of large-volume fluids.

[0026] 4. Since the equipment conveying chamber is independent and sealed to realize the transfer and transportation of fluid materials, the measurement accuracy coefficient during operation is not affected by the large error coefficient caused by changes in equipment operating speed, fluid viscosity, return flow, temperature and equipment aging.

[0027] 5. As far as the degree of sealing effect during operation is concerned, the entire cone disk and the opening and closing blades A, B, C assembly have sealing conditions during the rotating conveying process, and the sealing bearings on the connecting opening and closing hinges and the rotating shaft, as well as the design concept that the opening and closing blades A, B, C are located at the intersection of the center point of the spherical cavity and the apex of the cone angle of the cone disk, can be extended to infinitely close to the center to achieve sealing. In addition, located on the inner wall of the spherical cavity, the curvature of the opening and closing blades A, B, C is completely consistent with the curvature of the inner wall of the cavity and can maximize the sealing conditions of the rotation and sliding of the inner wall of the spherical cavity. Therefore, the design concept of the conveying equipment in terms of sealing and preventing fluid backflow has an extremely high degree of sealing.

[0028] 6. As for the friction loss of accessories during operation, since the entire rotating component and assembly are almost in a suspended state, rotating and conveying fluid in the spherical chamber in a mutual sliding manner without the phenomenon of direct metal hard friction surface or contact friction, there is no consumption of wearing parts, high friction coefficient and low energy conversion rate.

[0029] To sum up, in terms of comprehensive performance, conveying volume, metering accuracy and operating power consumption, compared with existing centrifugal pumps, turbine pumps, plunger pumps, water ring pumps, vane conveying pumps, etc., it has the advantages of high precision, small equipment size, strong stability, low manufacturing cost, convenient and flexible operation, simple and convenient maintenance, no metal friction and less loss, and low production cost.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 In this embodiment, a super-pressure fluid metering delivery pump includes a spherical cavity 1. The outer surface of the spherical cavity 1 is a standard hemisphere with fixed flanges on the edges, which are relatively assembled into a spherical cavity 1 with a standard inner circle by bolts. The inside of the two hemispheres needs to be assembled into the spherical cavity 1 according to the specific structure, and the following components are assembled according to the assembly process and position, and then relatively assembled and connected into one by flanges and bolts.

[0039] It should be noted that: the large diameter of the two fixed baffles 5 to be installed inside the spherical cavity 1 needs to be much smaller than the diameter of the inner wall of the spherical cavity 1 and larger than its radius; the cone radius of the two conical disks 8 needs to be close to or equal to the radius of the inner wall of the spherical cavity, and the bottom radius needs to be equal to or slightly larger than the large radius of the fixed baffle 5; the radius and outer fan-shaped curvature of each of the three groups of opening and closing blades A, B, C (9) are close to or the same as the radius and curvature of the inner wall of the spherical cavity 1.

[0040] In this embodiment, refer to Figure 4 Two rotating cone disks 8 are fixed to the front ends of the first rotating shaft 6 and the second rotating shaft 7, respectively. Then, the rotating shafts 6 and 7 are respectively passed through the middle holes of two fixed baffles 5 with bearing seats and bearings from the rear ends. The two fixed baffles 5 are moved along the rotating shaft to the bottom of the two cone disks 8 and reach a position close to the bottom surface of the cone disks 8 and are fixed by bearing connection, thereby forming two independent rotating devices. The bearings used are all sealed bearings.

[0041] refer to Figure 1 , Figure 2 , Figure 3 The cone disks 8 on the two rotating devices are opposite to each other at the vertex angle and intersect at a point as the rotating fulcrum. Figure 1The left side is closed between the conical surfaces of the two cone disks, leaving only a space for the three groups of opening and closing blades A, B, C (9) to rotate smoothly, while the other side is opened to the maximum angle. In this state, the angle between the two rotating devices composed of the first rotating shaft 6 and the second rotating shaft 7 is a standard angle, and the two rotating devices are combined together on the basis of this standard angle to form a complete set of rotating assembly devices.

[0042] like Figure 1 , Figure 2 Since the cone radius of the conical disk 8 is close to or equal to the radius of the inner wall of the spherical cavity 1, when the rotating cone point where the two apex angles of the conical disks 8 intersect is placed at the center point of the spherical cavity, the bottom edge of the conical disk 8 can be rotated and slid on the inner wall of the spherical cavity 1 at any orientation and angle; and at the bottom position of the conical disk 8, since the fixed baffle 5 with the same radius as the bottom surface of the conical disk 8 is parallel to each other, in this state, the other side surface of the fixed baffle 5 is also completely in contact with the inner wall of the spherical cavity 1 and has a fixing function that can be in any position.

[0043] refer to Figure 1 , Figure 2 After the vertex position of the rotating assembly is aligned with the center point position of the spherical cavity 1, two eccentric holes are respectively opened at positions extending outwardly along the rotating axes 6 and 7 to the spherical cavity wall area according to the rotating assembly of the first rotating axis 6 and the second rotating axis 7 at the standard angle, and the rotating axes 6 and 7 are respectively fixed to the spherical cavity 1 through the provided bearing seats as two fixed points of the two rotating axes on the outside of the spherical cavity wall. In addition, because the positions of the rotating axes 6 and 7 where the two fixed baffles 5 are respectively located are close to the inner wall of the spherical cavity at their respective positions, the two fixed baffles 5 can be directly fixed and sealed on the inner wall of the spherical cavity in this position state and serve as two fixed points of the two rotating axes 6 and 7 on the inner wall of the spherical cavity.

[0044] refer to Figure 1 On the outer wall of the area where the second rotating shaft 7 extends to the outside of the spherical cavity 1, a fixing seat 13 with a central hole for fixing the driving motor is fixed by a tubular fixing bracket and bolts, and then the driving motor 15 is connected to the motor rotor and the second rotating shaft 7 on the fixing seat 13, and the stator housing of the driving motor 15 is fixedly connected to the fixing seat 13 by bolts.

[0045] refer to Figure 5 Among the three groups of opening and closing blades A, B, and C (9) having a conveying function, the middle opening and closing parts of each group are connected by a connecting opening and closing hinge 901 to achieve a flexible opening and closing function.

[0046] refer to Figure 1 , Figure 2 and Figure 6First, the corresponding area between the conical surfaces of the two conical disks 8 is radially divided into three equal areas, and then the three groups of opening and closing blades A, B, C (9) are attached to the inner wall of the spherical cavity 1 in an arc toward the outside to achieve a position in a rotational transfer state. The two side edges of each group of opening and closing blades are connected to the corresponding three equal parts of the conical surfaces of the two conical disks 8 by connecting the opening and closing hinges 901, so that a linkage conveying device is formed between the two conical disks 8 and the inner wall of the spherical cavity 1 in synchronous rotation but with the three groups of opening and closing blades A, B, C (9) at different opening angles to separate them into three groups of conveying small chambers with different spatial volumes. That is to say, there are three groups of conveying fluids that are sucked into the conveying chamber when they are in the rotational opening process. The function of continuous conveying operation is achieved by the chamber in the state of entering the action state, the chamber in the state of extruding and discharging the conveyed fluid during the rotation closing process, and the chamber in the process of swirling and resetting. For example, when the second rotating shaft 7 is driven by the driving motor 15 to rotate the opening and closing blades A (9) and the corresponding position of the cavity to the left position of the spherical cavity 1 as shown in the figure, the opening and closing blades A (9) are in the closed state. In the process of rotating to the right side of the spherical cavity 1 under the action of continued rotation, the opening and closing blades A (9) will form a low-pressure suction fluid effect in the process of opening the small cavity through rotation, and then push it to the closed area of ​​the small cavity to form a high-pressure and high-pressure discharge fluid and swirling effect phenomenon. Therefore, based on this effect, the spherical cavity 1 position at the front end of the opening process position area of ​​the opening and closing blades A, B, C (9) is provided with a material input pipe 4 outwardly, and the spherical cavity 1 position at the front end of the closing process position area of ​​the opening and closing blades A, B, C (9) is provided with a material discharge pipe 11 outwardly.

[0047] refer to Figure 1 On the second rotating shaft 7, in the sensing area below the fixed seat 13, there is installed an inductive magnetic block 12 required for the Hall sensor so as to horizontally pass through the axis of the rotating shaft 7, and a Hall metering sensor 14 is installed on the inner side of the tubular fixed bracket at the lower part of the fixed seat 13 at the position corresponding to the magnetic block. The driving motor 15 fixed on the fixed seat 13 drives the rotating shaft 7, the cone disk 8, the connecting opening and closing hinge 901 and the opening and closing blades A, B, C (9) to rotate in a linked manner, so that the other group of cone disks 8 and the rotating shaft 6 rotate synchronously, so that the volume of the cavity space is in a state of continuous cyclic change, and the material conveying and inductive metering functions are performed.

[0048] In terms of sealing, firstly, since the standard arc of the inner wall of the spherical cavity 1 is completely consistent with the fan-shaped arc of the three groups of rotating blades A, B, C (9) on the outward side, a high sealing condition of a rotating sliding state can be formed to the maximum extent during the operation of the rotating opening and closing; in addition, the top angle area of ​​the rotating cone disk 8 at the other end of the opening and closing blades A, B, C (9) can form a sealing effect of mutually fitting rotational movement by extending to the maximum extent and intersecting at the center point of the spherical cavity 1; secondly, in this embodiment, the sealing method of the first rotating shaft 6 and the second rotating shaft 7 with the conveying cavity is to achieve the sealing effect by means of sealing bearings and sealing rings. Therefore, in the process of rotating and conveying operation of the conveying equipment, on the basis of controlling the rotating shaft not to reverse, the hinge 901 and various related components will not cause obvious mixing of materials, backflow, etc. when conveying fluid materials.

[0049] In terms of functional application, since the rotating shaft 6 and 7 and the cone disk have the function of rotating the small conveying chamber and the opening and closing blades A, B, C (9) in the process of opening and closing and isolating from each other, thus forming a basis for material transportation and conveying, if the rotating shaft 6 and 7, the cone disk 8 and the opening and closing blades A, B, C (9) on the disk are continuously pushed by the driving motor 15 or the pipeline's own flow pressure to form continuous opening and closing conveying, sliding and swirling, and under the condition of the sealing effect of each component, the operation process has a high-speed or low-speed rotation conveying, and even in a static state, there is no additional reflux phenomenon of the conveyed fluid, so that the conveyed material can be accurately measured during the continuous operation, and a strong vacuuming effect can be formed on the open chamber and the input pipeline, and the opposite side also has the characteristics of a high-pressure area and a discharge function that forms a strong pressurization effect on the closed chamber, the discharge pipeline and its output fluid material. This proves that the invention of the device can perfectly realize a multifunctional super-pressure fluid metering and conveying pump that has vacuuming, high-pressure conveying, accurate metering and pressurization effects on the pipeline and fluid materials.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
