Description

Technical Field

[0001] The present application relates to the technical field of liquid delivery pumps, and in particular to an optimization device for an aqueous solution delivery pump. Background Art

[0002] Aqueous solution refers to an aqueous solution composed of various metal ions. In the field of fluid transportation technology, centrifugal pumps are usually used as aqueous solution delivery pumps. A centrifugal pump is a pump that uses the centrifugal force of the rotating impeller to transport liquids. If the centrifugal pump is improperly operated during startup or operation or the transported liquid is vaporized in a low-pressure area, it will cause gas binding. The gas binding phenomenon refers to the centrifugal pump not being filled with the liquid to be transported before starting, or air infiltrating the pump during operation. The density of air is less than the density of the transported liquid, and the centrifugal force generated by the air is small. The centrifugal pump cannot throw the air out, and the pressure in the pump is reduced to be insufficient to suck the transported liquid into the pump, causing the centrifugal pump to lose its self-priming ability and be unable to transport liquid, just like being trapped by gas.

[0003] The air binding phenomenon not only reduces the conveying function of the centrifugal pump, but also causes dry grinding of the impeller in the pump, causing severe vibration of the centrifugal pump, which can easily lead to failure of the centrifugal pump. Therefore, improvements are now made to an aqueous solution conveying pump optimization device. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides an aqueous solution delivery pump optimization device, which overcomes the shortcomings of the prior art and aims to solve the problem that the aqueous solution delivery pump often causes air binding due to improper design or use, seriously affecting the efficiency and service life of the pump.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an aqueous solution delivery pump optimization device, comprising a base, characterized in that a centrifugal pump is fixedly installed on the upper surface of the base, one side of the centrifugal pump is transmission-connected to a drive motor, the water inlet and outlet of the centrifugal pump are respectively fixedly connected to an input pipe and an output pipe, the input pipe is fixedly installed with an air pressure detection container through a connecting pipe, an air pressure gauge is fixedly installed on one side of the upper surface of the air pressure detection container, a liquid replenishing unit is fixedly installed on the upper surface of the base on one side of the drive motor, and the liquid replenishing unit is connected to the output pipe through a one-way valve.

[0006] By adopting the above technical solution, the input pipeline and the air pressure detection container are connected through a connecting pipeline, so that the internal air pressure of the air pressure detection container can be detected by an air pressure gauge, thereby indirectly judging whether the centrifugal pump has an air binding phenomenon. When the centrifugal pump has an air binding phenomenon, through the cooperation among the liquid replenishing unit, the one-way valve and the output pipeline, a corresponding aqueous solution is input into the centrifugal pump to eliminate the air binding, so as to ensure that the centrifugal pump can suck in the liquid and maintain a normal operating state under the driving action of the driving motor.

[0007] As a preferred technical solution of the present application, the liquid replenishing unit includes a liquid storage tank fixedly installed on the upper surface of the base. A circulating pump is arranged on one side of the liquid storage tank, and the circulating pump is fixedly connected to the liquid storage tank and the one-way valve respectively through a liquid delivery pipe.

[0008] By adopting the above technical solution, by setting the one-way valve, it is ensured that the liquid inside the liquid storage tank can be transported into the centrifugal pump only unidirectionally through the circulating pump and the liquid delivery pipe.

[0009] As a preferred technical solution of the present application, a fixing seat is fixedly installed on the upper surface of the base on one side of the liquid storage tank, and the top of the fixing seat is in contact with the bottom of the circulating pump.

[0010] By adopting the above technical solution, the circulating pump is fixedly installed on the base through the fixing seat, preventing the circulating pump from shaking during operation, so as to ensure the stability of the whole system.

[0011] As a preferred technical solution of the present application, a liquid replenishing port is opened at the top of the liquid storage tank, and a sealing cover is slidably inserted into the inside of the liquid replenishing port.

[0012] By adopting the above technical solution, an aqueous solution can be added into the liquid storage tank. By setting the sealing cover, the airtightness of the internal space of the liquid storage tank is ensured, avoiding dust and small insects from falling into the liquid storage tank and contaminating the aqueous solution inside.

[0013] As a preferred technical solution of the present application, a ventilation cylinder is fixedly inserted at the center position of the upper surface of the air pressure detection container. A sealing block is arranged inside the ventilation cylinder. A limiting block is fixedly connected below the sealing block inside the ventilation cylinder. A blocking rod is arranged between the sealing block and the limiting block inside the ventilation cylinder. The lower end of the blocking rod slidably penetrates through the limiting block and is fixedly connected with a floating ball.

[0014] By adopting the above technical solution, the floating ball will float up and down as the liquid level inside the air pressure detection container rises or falls, thereby driving the blocking rod to slide in the limiting block and adjusting the position of the blocking rod.

[0015] As a preferred technical solution of the present application, a ventilation hole is provided on the outer wall of the ventilation tube near the upper end, a through hole is provided inside the sealing block, and the through hole is adapted to the blocking rod, and a plurality of air inlet holes are provided inside the limit block.

When the centrifugal pump stops running, negative pressure may be generated. At this time, the float will automatically drop with the liquid level, that is, a large amount of air can be inhaled through the cooperation between the air vent, the through hole and the air inlet to ensure the safety of the device.

[0017] As a preferred technical solution of the present application, a mounting seat is fixedly mounted on the upper surface of the base, and the top of the mounting seat fits with the bottom of the driving motor.

[0018] By adopting the above technical solution, the driving motor can be positioned to ensure the stability of the driving motor during operation and to prevent it from shaking at will.

[0019] As a preferred technical solution of the present application, a connecting flange is fixedly installed at one end of the input pipe away from the centrifugal pump, and a connecting flange is fixedly installed at one end of the output pipe away from the centrifugal pump.

[0020] By adopting the above technical solution, the connecting flange is used to ensure a firm connection between the output pipeline and the output pipeline and other pipelines, and the use of the connecting flange helps to ensure the stability and sealing of the connection and prevent medium leakage.

[0022] In the utility model, the input pipeline and the air pressure detection container are connected together by arranging a connecting pipeline, that is, the internal air pressure of the air pressure detection container can be detected by an air pressure gauge, so as to indirectly judge whether the centrifugal pump has air binding. When the centrifugal pump has air binding, the corresponding aqueous phase solution is input into the centrifugal pump through the cooperation between the liquid replenishment unit, the one-way valve and the output pipeline to eliminate the air binding, so as to ensure that the centrifugal pump can inhale liquid and maintain a normal operating state under the driving action of the driving motor, and the centrifugal pump can always maintain a normal air pressure to work through the cooperation between the air permeable cylinder, the float, the blocking rod, the sealing block and the limit block, so as to ensure the smooth operation of the centrifugal pump and the pipeline system.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0030] Such as Figure 1 - Figure 4As shown in the figure, an optimized device for a water-phase solution delivery pump provided in this embodiment includes a base 1. It is characterized in that a centrifugal pump 4 is fixedly installed on the upper surface of the base 1. A driving motor 2 is drivingly connected to one side of the centrifugal pump 4. The water inlet and outlet of the centrifugal pump 4 are respectively fixedly connected to an input pipeline 5 and an output pipeline 6. The input pipeline 5 is fixedly installed with a pressure detection container 10 through a communication pipeline 9. A pressure gauge 11 is fixedly installed on one side of the upper surface of the pressure detection container 10. A liquid supplement unit 8 is fixedly installed on the upper surface of the base 1 on the side of the driving motor 2. The liquid supplement unit 8 is communicated with the output pipeline 6 through a one-way valve 7. During use, by setting the communication pipeline 9 to connect the input pipeline 5 and the pressure detection container 10 together, the internal pressure of the pressure detection container 10 can be detected through the pressure gauge 11, so as to indirectly judge whether the centrifugal pump 4 has an air binding phenomenon. When the centrifugal pump 4 has an air binding, through the cooperation among the liquid supplement unit 8, the one-way valve 7 and the output pipeline 6, the corresponding water-phase solution is input into the centrifugal pump 4 to eliminate the air binding, so as to ensure that the centrifugal pump 4 can suck in the liquid under the driving of the driving motor 2 and maintain a normal operating state.

[0031] In this embodiment, as Figure 2 shown, the liquid supplement unit 8 includes a liquid storage tank 81 fixedly installed on the upper surface of the base 1. A circulation pump 83 is arranged on one side of the liquid storage tank 81. The circulation pump 83 is fixedly connected to the liquid storage tank 81 and the one-way valve 7 respectively through a liquid delivery pipe 84. During use, by setting the one-way valve 7, it is ensured that the liquid inside the liquid storage tank 81 can only be delivered into the centrifugal pump 4 unidirectionally through the circulation pump 83 and the liquid delivery pipe 84.

[0032] In this embodiment, as Figure 2 shown, a fixing seat 82 is fixedly installed on the upper surface of the base 1 on the side of the liquid storage tank 81. The top of the fixing seat 82 is in contact with the bottom of the circulation pump 83. During use, the circulation pump 83 is fixedly installed on the base 1 through the fixing seat 82 to prevent the circulation pump 83 from shaking during operation, so as to ensure the stability of the whole system.

[0033] In this embodiment, as Figure 2 shown, a liquid supplement port 85 is opened at the top of the liquid storage tank 81. A sealing cover 86 is slidably inserted into the inside of the liquid supplement port 85. During use, the water-phase solution can be added into the liquid storage tank 81. By setting the sealing cover 86, the airtightness of the internal space of the liquid storage tank 81 is ensured, and dust and small insects are prevented from falling into the liquid storage tank 81 and contaminating the internal water-phase solution.

[0034] In this embodiment, as Figure 3 and 4As shown, a ventilation cylinder 12 is fixedly inserted at the center of the upper surface of the air pressure detection container 10. A sealing block 16 is arranged inside the ventilation cylinder 12. A limiting block 18 is fixedly connected below the sealing block 16 inside the ventilation cylinder 12. A blocking rod 13 is arranged between the sealing block 16 and the limiting block 18 inside the ventilation cylinder 12. The lower end of the blocking rod 13 slides through the limiting block 18 and is fixedly connected with a floating ball 14. During use, the floating ball 14 will float up and down as the liquid level inside the air pressure detection container 10 rises or falls, thereby driving the blocking rod 13 to slide in the limiting block 18 and adjusting the position of the blocking rod 13.

[0035] In this embodiment, as Figure 3 and 4 shown, ventilation holes 15 are formed at a position near the upper end of the outer wall of the ventilation cylinder 12. A through hole 17 is formed inside the sealing block 16, and the through hole 17 is adapted to the blocking rod 13. A number of air inlet holes 19 are formed through the inside of the limiting block 18. During use, when the centrifugal pump 4 is working normally to transport the solution, there is liquid inside the air pressure detection container 10. The through hole 17 is blocked through the cooperation between the floating ball 14 and the blocking rod 13, so that the centrifugal pump 4 can always work under a normal air pressure. When the centrifugal pump 4 stops running, negative pressure may be generated. At this time, the floating ball 14 will automatically drop with the liquid level, that is, a large amount of air can be inhaled through the cooperation between the ventilation holes 15, the through hole 17 and the air inlet holes 19 to ensure the safety of the device.

[0036] In this embodiment, as Figure 1 shown, a mounting seat 3 is fixedly installed on the upper surface of the base 1. The top of the mounting seat 3 is in contact with the bottom of the driving motor 2. During use, it can play a positioning role for the driving motor 2, ensure the stability of the driving motor 2 during operation, and ensure that it will not shake randomly.

[0037] In this embodiment, as Figure 1 shown, a connecting flange 20 is fixedly installed at one end of the input pipe 5 away from the centrifugal pump 4. A connecting flange 20 is fixedly installed at one end of the output pipe 6 away from the centrifugal pump 4. During use, the connecting flange 20 is used to ensure the firm connection between the output pipe 6 and other pipes, and the use of the connecting flange 20 helps to ensure the stability and tightness of the connection and prevent medium leakage.

[0038] Working principle: When using an optimized device for an aqueous solution delivery pump of the present application, the input pipeline 5 and the air pressure detection container 10 are connected together by setting up a connecting pipeline 9. That is, the internal air pressure of the air pressure detection container 10 can be detected through the air pressure gauge 11, so as to indirectly judge whether the centrifugal pump 4 has an air binding phenomenon. When the centrifugal pump 4 has an air binding, through the cooperation among the liquid supplementing unit 8, the one-way valve 7 and the output pipeline 6, the corresponding aqueous solution is input into the centrifugal pump 4 to eliminate the air binding, so as to ensure that the centrifugal pump 4 can suck in liquid under the driving action of the driving motor 2 and maintain a normal operating state. When the centrifugal pump 4 is working normally to deliver the solution, there is liquid in the air pressure detection container 10. Through the cooperation between the floating ball 14 and the blocking rod 13, the through hole 17 is blocked, so that the centrifugal pump 4 can always work under a normal air pressure. When the centrifugal pump 4 stops running, negative pressure may be generated. At this time, the floating ball 14 will automatically drop with the liquid level. That is, through the cooperation among the air vent hole 15, the through hole 17 and the air inlet hole 19, a large amount of air can be inhaled to ensure the safety of the device and ensure the smooth operation of the centrifugal pump 4 and the pipeline system.
