Description

Technical Field

[0001] This utility model relates to a high-pressure water spray pump set. Background Technology

[0002] In northern winters, train carriages loaded with coal often freeze solid when unloading, sometimes preventing half of the coal from being removed. Currently, there is no equipment for cleaning frozen coal from train carriages during winter; all cleaning is done manually. This manual process is extremely costly and inefficient. The risk of falls from heights is immense, posing a significant safety hazard, especially for workers getting on and off the trains to remove coal. Furthermore, the carriage doors need to be opened and resealed after the coal is removed. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a high-pressure water spray pump set.

[0004] The purpose of this utility model is achieved through the following technical solution: a high-pressure water spray pump set, including a water pump, which is connected to a first pump set tank. The bottom of the first pump set tank is connected to a second pump set tank via a connecting pipe. A booster pump is connected to the first and second pump set tanks. The air outlet of the booster pump is connected to a pump head. Each tank is equipped with a level gauge and multiple heaters. Each tank is equipped with an air pump on its side wall. Each air pump is connected to an exhaust valve, a safety valve, and an air inlet valve. A backup pressure sensor is also connected to the air inlet valve. A pressure sensor is installed inside the tank. The water spray pump set is controlled by a PLC in an electrical cabinet.

[0005] A further improvement of this utility model is that the water pump is connected to a three-phase asynchronous motor.

[0006] A further improvement of this utility model is that each tank is a multi-layer composite tank, and the multi-layer composite tank is provided with an anti-corrosion layer and a heat insulation layer.

[0007] A further improvement of this utility model is that the pressure pump has a dual-pump structure.

[0008] This utility model has the following advantages compared with the prior art: This invention employs a high-pressure pump unit to spray anti-icing agent at high pressure, thereby dissolving and dispersing residual and frozen coal. This reduces labor costs, significantly improves the efficiency of removing residual and frozen coal, saves more time to complete more carloads, and avoids the risk of personnel falling while climbing in and out of the carloads. The carload doors do not need to be opened or resealed, and the cleaning of residual and frozen coal is completed intact. Attached Figure Description

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Elements and features described in one embodiment of this utility model can be combined with elements and features shown in one or more other embodiments. It should be noted that, for clarity, representations and descriptions of components and processes unrelated to this utility model and known to those skilled in the art are omitted in the description. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0011] A high-pressure water spray pump set includes a water pump 1, which is connected to a first pump set tank 2. The bottom of the first pump set tank 2 is connected to a second pump set tank 4 via a connecting pipe 3. Each tank is a multi-layer composite tank with an anti-corrosion layer and an insulation layer. The first pump set tank 2 and the second pump set tank 4 are connected to a booster pump 5, which is a dual-pump structure. The air outlet of the booster pump 5 is connected to a pump head. Both tanks are equipped with a level gauge 6 and multiple heaters 7. Both tanks are equipped with air pumps 8 on their side walls. Each air pump 8 is connected to an exhaust valve 9, a safety valve 10, and an air inlet valve 11. A pressure sensor 12 is also connected to the air inlet valve 11. A pressure sensor is installed inside the tank. The water spray pump set is controlled by a PLC in an electrical cabinet 13.

[0012] A water pump 1 is connected to a three-phase asynchronous motor. The water pump 1 first draws liquid into the first pump group tank 2. Once the first pump group tank 2 is full, the liquid flows through the connecting pipe 3 at the bottom of the first pump group tank 2 into the second pump group tank 4, where it is stored. When spraying is needed, the liquid in the first pump group tank 2 is output through the pressurizing pump 5 and then sprayed out through the pump head. When the pressure sensor 12 at the top of the tank detects that the air pressure inside the tank has become negative, it sends a signal to the electrical cabinet, which in turn sends a signal to the air pump 8. The air inlet valve 11 opens, and the air pump 8 draws air into the tank through the air inlet valve 11. When the air pressure inside the tank returns to normal, the air pump 8 and the air inlet valve 11 close. When the air pressure inside the tank is too high, the exhaust valve 9 opens to release some gas, restoring the air pressure inside the tank to normal. When the air pressure inside the tank approaches its maximum limit, the safety valve 10 opens to quickly release gas and prevent the tank from exploding.

[0013] This invention employs a high-pressure pump unit to spray anti-icing agent at high pressure, thereby dissolving and dispersing residual and frozen coal. This reduces labor costs, significantly improves the efficiency of removing residual and frozen coal, saves more time to complete more carloads, and avoids the risk of personnel falling while climbing in and out of the carloads. The carload doors do not need to be opened or resealed, and the cleaning of residual and frozen coal is completed intact.

[0014] Finally, it should be noted that although the present invention and its advantages have been described in detail above, it should be understood that various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present invention as defined by the appended claims. Furthermore, the scope of the present invention is not limited to the specific embodiments of the processes, apparatus, means, methods, and steps described in the specification.
