Description

Technical Field

[0001] This utility model relates to the technical field of horizontal pump measuring tanks, specifically an auxiliary horizontal pump measuring tank. Background Technology

[0002] The filtration pump room in the mineral processing department has multiple horizontal pumps responsible for transporting slurry or water to the filtration platform and underground pump pool. The height difference between the inlet of the horizontal pump and the medium pool is about ten meters. When the horizontal pump is started, due to the large height difference and the presence of air in the pipeline, the slurry and water cannot be effectively transported, resulting in pump cavitation and insufficient flow. Hard starts will cause pump vibration and motor overheating, which will damage the equipment. Therefore, we propose an auxiliary horizontal pump flow tank. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary horizontal pump metering tank to solve the problem mentioned in the background art, where multiple horizontal pumps in the filtration pump room of the mineral processing department are responsible for transporting slurry or water to the filtration platform and underground pump pool. The height difference between the inlet end of the horizontal pump and the medium pool is about ten meters. When the horizontal pump is started, due to the large height difference and the presence of air in the pipeline, the slurry and water cannot be effectively transported, resulting in pump cavitation and failure to meter. Hard starts will cause pump vibration and motor overheating, which will damage the equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary horizontal pump measuring tank, comprising:

[0005] The upper measuring water tank has a water injection pipe and an exhaust check valve installed on its top. A second connecting flange is integrally fixedly installed at the end of the water injection pipe away from the upper measuring water tank. A drain pipe and a slag removal pipe are installed at the bottom of the upper measuring water tank. An on / off valve is installed on the right side of the slag removal pipe. A first connecting flange is integrally fixedly installed at the end of the drain pipe away from the upper measuring water tank. Support legs are welded to the outer surface of the upper measuring water tank. A ceramic sheet liner is fixedly installed on the inner wall of the upper measuring water tank.

[0006] As a preferred embodiment of the auxiliary horizontal pump water tank of this utility model, the water tank is connected to the exhaust check valve and the water injection pipe.

[0007] In a preferred embodiment of the auxiliary horizontal pump measuring tank of this utility model, the drain pipe penetrates the inner wall of the measuring tank, and the upper end of the drain pipe is lower than the upper end of the measuring tank.

[0008] In a preferred embodiment of the auxiliary horizontal pump measuring tank of this utility model, the slag removal pipe is connected to the measuring tank, and the slag removal pipe is connected to the on / off valve.

[0009] As a preferred embodiment of the auxiliary horizontal pump water tank of this utility model, the water injection pipe is further provided with:

[0010] A through hole is formed inside the water injection pipe. A baffle is movably installed on the left side of the through hole. A return spring is installed on the left side of the baffle. The baffle can rotate inside the water injection pipe. The baffle is elastically connected to the water injection pipe through the return spring.

[0011] Compared with the prior art, the present invention provides an auxiliary horizontal pump measuring tank, which has the following beneficial effects:

[0012] 1. This utility model, by setting up a measuring water tank and a drain pipe, and filling the measuring water tank with water, allows the water to enter the drain pipe under the action of gravity and come into contact with the water pump. This provides a continuous liquid column to the pump inlet before the pump starts, effectively overcoming the problem of horizontal pumps not being able to start and produce flow due to large height differences and air accumulation in the inlet pipe. This ensures that the pump can quickly and reliably establish normal flow. Furthermore, by using the siphon principle, it ensures that the pump inlet is always full of medium during operation, fundamentally preventing serious equipment failures such as severe vibration, cavitation, bearing seal damage, and motor overheating and burnout caused by cavitation, thus extending the pump set life and reducing maintenance costs.

[0013] 2. This utility model, by setting a reset spring, a baffle and a through hole inside the water injection pipe, when the horizontal pump stops working, the baffle will be pushed by the elastic force of the reset spring and the negative pressure on the right side of the through hole to firmly cover the through hole, so that the water in the liquid inlet pipe will not fall, and no manual intervention is required for the next use.

[0014] 3. This utility model has a simple structure, low cost, strong versatility, and wide applicability. It completely solves the problem of pumps not working properly and uses wear-resistant ceramic plates to line the tank, extending the service life of the tank. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-3 An auxiliary horizontal pump measuring tank includes a measuring tank 1. A water injection pipe 7 and an exhaust check valve 9 are installed on the top of the measuring tank 1. A second connecting flange 8 is integrally fixedly installed at the end of the water injection pipe 7 away from the measuring tank 1. A drain pipe 4 and a slag removal pipe 5 are installed at the bottom of the measuring tank 1. An on / off valve 6 is installed on the right side of the slag removal pipe 5. A first connecting flange 3 is integrally fixedly installed at the end of the drain pipe 4 away from the measuring tank 1. Support legs 2 are welded to the outer surface of the measuring tank 1. A ceramic sheet liner 10 is fixedly installed on the inner wall of the measuring tank 1.

[0021] In this implementation scheme: by setting up a water tank 1 and a drainage pipe 4, and filling the water tank 1 with water, the water enters the drainage pipe 4 under the action of gravity and comes into contact with the water pump. This provides a continuous liquid column to the pump inlet before the pump starts, effectively overcoming the problem of horizontal pumps not being able to start and produce flow due to large height differences and air accumulation in the inlet pipe. This ensures that the pump can quickly and reliably establish normal flow. Furthermore, by utilizing the siphon principle, the pump inlet is always filled with medium during operation, fundamentally preventing serious equipment failures such as severe vibration, cavitation, bearing seal damage, and motor overheating and burnout caused by cavitation. This extends the pump set life and reduces maintenance costs. At the same time, this utility model has a simple structure, low cost, strong versatility, and wide applicability. It completely solves the problem of pumps not flowing smoothly, and uses wear-resistant ceramic plates to line the tank body, extending the service life of the tank body.

[0022] Furthermore:

[0023] In an optional embodiment, the upper water tank 1 is connected to the exhaust check valve 9, and the upper water tank 1 is connected to the water injection pipe 7.

[0024] In this implementation plan: when the water tank 1 is filled with water, the air inside the water tank 1 can be discharged through the exhaust check valve 9.

[0025] Furthermore:

[0026] In an optional embodiment, the drain pipe 4 passes through the inner wall of the upper water tank 1, and the upper end of the drain pipe 4 is lower than the upper end of the upper water tank 1.

[0027] In this implementation plan: when water is discharged downward from the drainage pipe at point 4, a siphon effect is formed, reducing the working pressure of the horizontal pump.

[0028] Furthermore:

[0029] In an optional embodiment, the slag removal pipe 5 is connected to the water supply tank 1, and the slag removal pipe 5 is connected to the on / off valve 6.

[0030] In this implementation plan: water can be stored through the slag removal pipe 5 and the on / off valve 6, and slag can also be discharged through the slag removal pipe 5 and the on / off valve 6.

[0031] Furthermore:

[0032] In an optional embodiment, the water injection pipe 7 is further provided with:

[0033] A through hole 13 is formed inside the water injection pipe 7. A baffle 12 is movably installed on the left side of the through hole 13. A return spring 11 is installed on the left side of the baffle 12. The baffle 12 can rotate inside the water injection pipe 7. The baffle 12 is elastically connected to the water injection pipe 7 through the return spring 11.

[0034] In this implementation plan: by setting a reset spring 11, a baffle 12 and a through hole 13 inside the water injection pipe 7, when the horizontal pump stops working, the baffle 12 will be pushed by the elastic force of the reset spring 11 and the negative pressure on the right side of the through hole 13 to firmly cover the through hole 13, so that the water in the liquid inlet pipe will not fall, and no manual intervention is required when using it next time.

[0035] Working Principle: When using this auxiliary horizontal pump to fill the water tank, firstly connect the inlet pipe of the horizontal pump to the drain pipe 4 through the first connecting flange 3, and then connect the water injection pipe 7 to the liquid inlet pipe through the second connecting flange 8. The liquid inlet pipe extends into the medium tank. Next, connect the on / off valve 6 to the water pump. When the water pump works, it fills the water tank 1 through the sludge removal pipe 5. During the water filling process, the gas inside the water tank 1 is discharged through the exhaust check valve 9. When water is discharged from the exhaust check valve 9, it indicates that the water tank 1 is full. Stop the water filling and close the on / off valve 6. Then, the horizontal pump is powered on and works. By draining the water from the water tank 1 through the drain pipe 4, a negative pressure is formed inside the water tank 1. This causes water to be drawn from the medium tank through the water injection pipe 7 and the liquid inlet pipe and injected into the water tank 1. At the same time, the liquid level inside the water tank 1 is higher than that in the drain pipe. At this point, a balance is formed on the upper surface of channel 4. The water inside the upper measuring tank 1 is discharged through the drain pipe 4 and the horizontal pump. The water in the medium pool is injected into the upper measuring tank 1 through the water injection pipe 7 and the liquid inlet pipe. The liquid level in the upper measuring tank 1 is higher than the upper surface of the drain pipe 4, which ensures that the horizontal pump can work continuously and efficiently. When the horizontal pump stops working, the reset spring 11 pushes the baffle 12 to cover the through hole 13 through its own elasticity. The water inside the liquid inlet pipe moves downward under the action of gravity, and the negative pressure formed sucks the baffle 12 to tightly cover the through hole 13. In this way, the water inside the liquid inlet pipe will remain in the liquid inlet pipe. When the horizontal pump is started again, the water in the medium pool can be directly pumped out. Finally, the on / off valve 6 can be opened to discharge the water inside the upper measuring tank 1 and the impurities inside the slag removal pipe 5, which achieves the effect of slag removal. This is the working principle of the upper measuring tank of the auxiliary horizontal pump.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
