Description

Technical Field

[0002] The connection between the water outlet of the high-pressure tank cleaning machine and the high-pressure pump is usually directly connected by a water outlet joint clearance hose. In this structure, when the high-pressure pump absorbs water from the water tank, the liquid level gradually decreases, and the large flow of water will rotate to form a hollow vortex; then a large amount of air enters the high-pressure pump with the vortex water flow, causing the high-pressure pump to vibrate violently and cause cavitation in the pump, resulting in a reduction in the life of the high-pressure pump and damage. At the same time, the entry of air causes slow water absorption, the water tank liquid level cannot be lowered normally, and the low water level protection switch cannot play a protective role. If the installation position of the low water level protection switch is raised, it will also lead to serious waste of the effective volume of the water tank. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Reference Figure 1-4 A high-pressure tank cleaning machine uses a water tank water outlet anti-vortex air suction device, comprising: an anti-vortex air intake component 1, an internally threaded water tank joint 2 threadedly connected to the anti-vortex air intake component 1, a locking nut 4 for fixing the anti-vortex air intake component 1 to the water tank, and a water outlet pagoda 5; the anti-vortex air intake component 1 is the core part of the entire device structure, and can effectively suppress the water flow vortex and vortex center air intake formed when the water level is low and the flow rate is large when absorbing water, so as to prevent air from being sucked into the high-pressure pump.

[0018] The anti-vortex air intake assembly 1 includes an air blocking piece 1-1, a plurality of water vortex blocking pieces 1-2 fixedly connected to the air blocking piece 1-1, and a threaded connection port 1-3 fixedly connected to the water vortex blocking piece 1-2, wherein the threaded connection port 1-3 is threadedly connected to the internal thread water tank joint 2. The water vortex blocking piece 1-2 is used to suppress the rotation of the water flow formed when a large flow of water is absorbed, and to avoid the formation of a vortex water flow hollow. The air blocking piece 1-1 is used to block the hollow formed from the center of the water vortex to prevent air from being brought into the water flow and being sucked into the high-pressure pump from the water outlet.

[0019] Furthermore, one side of each two water vortex blocking sheets 1-2 is fixedly connected, and the multiple water vortex blocking sheets 1-2 are connected to form a propeller blade shape. The multiple water vortex blocking sheets 1-2 divide one side of the air blocking sheet 1-1 into multiple intervals.

[0020] Furthermore, the threaded connection port 1-3 is fixedly connected to a plurality of water vortex blocking plates 1-2, and the threaded connection port 1-3 is used to be threadedly connected to the internal threaded water tank joint 2 fixed to the bottom of the water tank, so as to facilitate the fixing of the anti-vortex air intake device. A water flow channel 1-4 is formed between the space inside the threaded connection port 1-3 and each interval, and the water flow channel 1-4 provides a fixed flow channel for the water flow, and introduces water into the water pipe below to connect the water outlet pagoda 5. The water outlet pagoda 5 is connected to the water flow channel 1-4, and a water outlet hose is fixedly connected to the end of the water outlet pagoda 5 away from the water tank, and the water outlet pagoda 5 transports water to the water inlet of the high-pressure pump.

[0021] Further, a sealing gasket 3 is provided between the internal thread water tank joint 2 and the water tank. The sealing gasket 3 can achieve a water-leakage-proof seal after being compressed.

[0022] like Figure 1 The low water level protection switch shown in the figure is installed at the bottom of the water tank, and the device of the present invention is also installed at the bottom opening of the water tank and is level with the low water level protection switch. During installation, after the water tank is opened, the inner threaded water tank joint 2, the sealing gasket 3, the locking nut 4 and the water outlet pagoda 5 are pre-installed at the bottom opening of the water tank, and then the outer thread of the anti-vortex intake assembly 1 is tightened to the thread of the inner threaded water tank joint 2 on the inner side of the water tank and fixed.

[0023] When the liquid level is relatively high, the high-pressure pump draws water from the water tank, and the water flow does not rotate enough to form a hollow, that is, air will not enter the high-pressure pump. When the liquid level gradually drops to a low level, the high-pressure pump draws water at a large flow rate, causing the water flow to rotate at a high speed at the water outlet of the water tank, and a hollow vortex begins to form. The air blocking sheet 1-1 can block the air in the hollow formed in the middle of the vortex, and water can only enter the lower part from both sides of the device, thereby isolating the air from entering, ensuring that water can only flow in from both sides of the device, and flow out through the water flow channel 1-4 into the water outlet pagoda 5, and then flow into the high-pressure pump.

[0024] At the same time, the cross-shaped blocking plates 1-2 distributed among the water vortex blocking plates will block the rotation of the water flow in four parts, reduce the flow rate of the water flow rotation, and further reduce the formation energy of the water vortex, further avoid the formation of a hollow water vortex, and isolate air from entering.

[0025] As the high-pressure pump steadily absorbs water, the gradual decrease in water level will trigger the low water level protection switch, thereby stopping the operation of the high-pressure pump, achieving water shortage protection, preventing the high-pressure pump from running dry, avoiding damage to the pump unit and extending its service life.

[0026] To sum up, the present invention effectively suppresses the formation of water vortex at the water tank outlet through the unique water vortex blocking plate and air partition plate, thereby avoiding severe shaking and internal cavitation of the high-pressure pump caused by air entering the high-pressure pump when the water level is low, and avoiding damage to the high-pressure pump.

[0027] The lower height, combined with the low water level protection switch, can greatly improve the utilization rate of the effective volume of the water tank, so that the water in the water tank can be sucked away by the high-pressure pump to the greatest extent.

[0028] The device has a simple structure, the threaded connection is firm and reliable, and it is easy to deploy. It can be used with any metal or non-metal flat-bottom water tank. It only requires drilling holes, no welding, and saves manpower and material costs.

[0029] The number of devices and processing scale described here are used to simplify the description of the utility model. The application, modification and variation of the utility model are obvious to those skilled in the art.

[0030] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described here.
