Detailed Description

First of all, it should be noted that the specific structure, characteristics, advantages, etc. of the novel rapid flow increasing device of the present invention will be specifically described below by way of example, however, all the descriptions are only for illustrative purpose and should not be construed as forming any limitation to the present invention. Furthermore, any single feature described or implicit in any embodiment or any single feature shown or implicit in any drawing may still be combined or subtracted between any of the features (or equivalents thereof) to obtain still further embodiments of the invention that may not be directly mentioned herein. In addition, for the sake of simplicity, the same or similar features may be indicated in only one place in the same drawing.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. In contrast, when an element is said to be "directly connected" to another element, it is intended that no intervening element is present.

For further understanding of the contents, features and functions of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:

the first embodiment is as follows:

the novel rapid flow increasing device is installed at a fluid outlet and comprises a round pipe 1 with a length of L, L is not less than 3d and not more than 4d, d is the diameter of the round pipe, and a vacuum breaking device 2 is arranged at the position of 0.8d of the edge of the round pipe.

The working process is as follows: water flow enters the pipe section from the left side until the pipe section is filled with the water flow, so that full pipe outflow is formed, a vacuum negative pressure state appears at the position shown in the figure under the action of outflow of the pipe nozzle, siphonage is formed, the flow rate of the water flow is accelerated, and meanwhile, the flow is increased.

Example two:

as shown in the attached drawing 2, further, the vacuum breaking device of the present invention includes a breaker housing 3, a piston a4 and a piston B5, the piston a seals the breaker housing, the piston B seals the circular tube, the piston a and the piston B are fixed by a connecting rod 6, a fixing rod 7 is disposed between the piston a and the circular tube, the fixing rod is a telescopic sleeve, a spring 8 is sleeved outside the fixing rod, one end of the spring abuts against the piston a, the other end abuts against the circular tube, and when the vacuum breaking device does not work, the spring is in a natural extension state.

Preferably, the diameter of the piston a is larger than the diameter of the piston B.

The working process is as follows: water flow enters the pipe section from the left side until the pipe section is filled with water to form full pipe outflow, and a vacuum negative pressure state appears at the position of the vacuum area 10 shown in the figure under the action of the outflow of the pipe nozzle, so that siphon is formed, the flow rate of the water flow is accelerated, and the flow is increased. When the water head is larger than 9 meters before water flows out or external positive pressure exists in the device, the vacuum breaker positioned above the pipeline can automatically open the piston, firstly, the gas in the vacuum breaker is released, and then, external fluid is communicated to break the vacuum environment in the pipeline, so that the normal operation of the device is protected. The external fluid may be air.

In order to prevent the device from sucking air from an outlet to cause damage due to overlarge vacuum degree or prevent the device from being damaged due to the combined action of external pressure of the device and vacuum in the device, a vacuum breaking device is designed at the position with the maximum negative pressure to prevent the situation from happening. The whole equipment is of a steel structure except the vacuum breaker, when the vacuum degree in the pipe section is close to 7-8 meters of water column, the piston of the breaker moves downwards, other fluids are sucked from the outside of the pipe section, and the pipe is prevented from vaporizing the liquid inside and causing cavitation to the pipe section.

Example three:

at present, internal tests are carried out, the device is used for salvaging blue algae in key areas of the Dian pond and is assembled at the outlet of a blue algae drawing head, and the original flow is 2000m³The flow rate of the/h suction head is increased to 2590m after the flow increasing device is assembled³The outflow efficiency is improved by 29.5 percent, and the main effect is that the flow rate of the liquid is improved, so that the collection of the blue algae flowing along with the liquid is accelerated.

Note that:

1. the flow increasing device is only suitable for increasing the fluid in a full pipe flow state, and other devices with other sizes are needed if the flow cannot fill the pipe section;

2. the device cannot bear fluid corrosive to the steel structure;

3. if the vacuum breaker is started in the use process, please ensure that the fluid in the device does not react with the fluid outside the device or influence the use purpose;

4. the device is strictly forbidden to use working environments with external pressure exceeding the normal working pressure range of the destructor.
