Description

TECHNICAL FIELD

The present application relates to a vortex water flow accelerator.

BACKGROUND

Vortex water flow accelerators are common in fish culture tanks. The vortex water flow accelerator is usually connected to the nozzle of the water outlet pipe of a suction pump. The flow rate of the water in the water outlet pipe is increased and produces a swirl effect under the function of the vortex water flow accelerator, which can increase the water circulation and enhance the filtration effect. The existing vortex water flow accelerator has a simple structure, in which usually only a plurality of spiral blades are arranged in the direction of water flow, and the water flows through the spiral blades to form vortex water; the existing vortex water flow accelerator can play the function of acceleration, but the acceleration effect is not very good, so it needs to be further improved by structural optimization.

SUMMARY

In view of the shortcomings of the above problems, the present application provides a vortex water flow accelerator.

In order to achieve the above purpose, the present application provides a vortex water flow accelerator, which includes a joint pipe with a water inlet and a water outlet, a water outlet barrel connected to a water outlet end of the joint pipe, and a plurality of spiral blades arranged in the water outlet barrel and connected with the joint pipe, wherein the water inlet is connectable with a water outlet pipe of a suction pump, the size of the water outlet is smaller than that of the water inlet, and an inner wall of the joint pipe forms an annular surface and a first conical surface in turn from along a direction from the water inlet to the water outlet, and an outer wall of the joint pipe is formed with a second conical surface on which a plurality of splitter plates uniformly distributed at the circumference are formed; the splitter plates protrude from a water outlet end face of the joint pipe, the water outlet barrel has a small diameter end and a large diameter end, and the small diameter end is connected to the splitter plates, so that a secondary water inlet is formed between the second conical surface, the water outlet barrel and two adjacent splitter plates; an upper edge of the spiral blade (3) is attached to the splitter plate, and an outer edge of the spiral blade (3) is attached to an inner wall of the water outlet barrel; a lower edge of the spiral blade (3) extends to the position of the large diameter end (22), and an inner edge of the spiral blade (3) is spirally bent and retracted from the circumference of the water outlet (12) to the center of a circle.

The size of the outlet is smaller than that of the inlet, and the cross-section decreases, so that the flow velocity increases. The first conical surface can well reduce the resistance to water flow, so that the flow velocity increases to the maximum. The second conical surface also gives the minimum resistance to water flow, and the spiral blades are spirally bent and retracted, so that after the water at the inlet and the water at the secondary inlet enter the outlet barrel, the two parts of water interact with each other to form a larger vortex, which results in a large amount of water and a large flow velocity.

As a further improvement of the solution, a locking interface is formed on the splitter plate, and the small diameter end is positioned and installed at the locking interface.

In the above technical solution, the design of the locking interface makes the assembly of the water outlet barrel simple.

As a further improvement of the solution, a middle part of the water outlet barrel retracts inward in a thin waist shape.

In the above technical solution, the design of the thin waist makes the spiral blade have a longer path when bending in the water outlet barrel, and the water flow forms a larger vortex under the action of the spiral blade.

As a further improvement of the solution, a thickness of the spiral blade decreases along a direction from the upper edge to the lower edge.

In the above technical solution, the gradual design of the thickness further promotes the formation of vortex water flow.

Compared with the prior art, the present application has the beneficial effects that the size of the water outlet is smaller than that of the water inlet, and the cross section is reduced to increase the flow velocity; the first conical surface can well reduce the resistance to the water flow, so that the flow velocity increases to the maximum; the second conical surface also gives the minimum resistance to the water flow; and the spiral blades are spirally bent and retracted, so that after the water at the water inlet and the water at the secondary water inlet enter the water outlet barrel, the two parts of water interact to form a larger vortex.

The size of the outlet is smaller than that of the inlet, and the cross-section decreases, so that the flow velocity increases. The first conical surface can well reduce the resistance to water flow, so that the flow velocity increases to the maximum. The second conical surface also gives the minimum resistance to water flow, and the spiral blades are spirally bent and retracted, so that after the water at the inlet and the water at the secondary inlet enter the outlet barrel, the two parts of water interact with each other to form a larger vortex, which results in a large amount of water and a large flow velocity.

When in use, in order to facilitate the understanding of the present application, it is described with reference to the attached drawings.

The water flow enters from the water inlet of the joint pipe, and passes through the annular surface 13 and the first conical surface 14 to the water outlet. As the cross-section decreases, the water flow speed increases, and the resistance of the first conical surface to the water flow is small. The accelerated water flows through the water outlet and impacts the lower half of the spiral blade, forming a high-speed vortex along the surface of the spiral blade, while in the upper half of the spiral blade, a negative pressure is formed. The negative pressure makes the external water enter from the secondary water inlet, and the water volume increases. The resistance of the second cone to the water flow is small, and the water entering from the secondary water inlet flows along the upper part of the spiral blade to form a vortex in advance, which drives the water flowing through the water outlet to rotate, so that part of the water flowing through the water outlet spreads outward to the upper half of the spiral blade before impacting the lower half of the spiral blade, that is, a certain air swirl is formed in the middle of a plurality of spiral blades, and the water flowing from the water outlet and the secondary water inlet interact with each other to form a larger vortex on the circumference and an air swirl at the center of the circle, which greatly increases the flow rate of the water flowing out of the water outlet barrel.

The above is only the preferred embodiment of the present application, and it is not intended to limit the present application. For those skilled in the art, the present application can be modified and varied. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
