Problems solved by technology

However, in recent years, harmful algal blooms that are more harmful have mostly appeared in waters that are closely related to human activities, such as fjords with shallow water and complex scenes, shallow ponds, breeding areas, and bathing places. There is still a lack of portable, High-efficiency, flexible control algaecide special spraying device
[0004] Modified clay has the characteristics of high bulk coefficient and high viscosity coefficient increase when encountering water. The single traditional fluidized bed transportation technology is often unable to complete the mechanical transportation of this material.
Moreover, the existing equipment either has a complex structure and a heavy body for the pursuit of mechanized operations; or simply borrows spraying devices such as pesticide sprayers for the pursuit of simplicity, or uses manual operations, so the equipment has poor versatility and low operating efficiency. Suitable for application of modified clay powder

Embodiment 1

[0038] Such as Figure 2-3 As shown, the feed port 11 of the negative pressure feed pipe is in the shape of a slit flat mouth, and multiple groups of feed valve outlets 12 are preferably arranged diagonally on the dial valve 8, and each feed valve outlet 12 is a five-sided shaped structure. By rotating the dial valve 8, one group of dial valve discharge ports 12 can be made to correspond to the negative pressure feed pipe feed port 11.

Embodiment 2

[0040] Such as Figure 4-5As shown, the feed port 11 of the negative pressure feed pipe is a symmetrical triangular structure, and the dial valve 8 is symmetrically provided with multiple sets of triangular-shaped feed valve outlets 12, and one of them can be made by rotating the dial valve 8. The discharge port 12 of the dial valve corresponds to the feed port 11 of the negative pressure feed pipe. The quantity of the material outlet 12 of the dial valve can be adjusted according to the feed demand.

[0041] Modified clay has the characteristics of high bulk coefficient and high viscosity coefficient increase when encountering water. The single traditional fluidized bed transportation technology is often unable to complete the mechanized transportation of the material. Existing special equipment for the elimination of harmful algal blooms is either complicated in structure and bulky in pursuit of mechanization; or simply borrows spraying devices such as pesticide sprayers in...

Abstract

The invention belongs to the technical field of harmful algal bloom treatment, and particularly relates to a spraying device of a harmful algal bloom eliminating agent. The spraying device comprises ahopper, a Venturi jet pipe, a stirring device and a negative pressure feed pipe, wherein the bottom of the hopper communicates with a throat of the Venturi jet pipe through the negative pressure feedpipe, the stirring device is arranged in the hopper and used for stirring the agent in the hopper, and a hydraulic vibrator is arranged on the side wall of the hopper. The spraying device overcomes the limitation of the property change of harmful algal bloom eliminating agent materials such as modified clay on the applicability of matched equipment, has the advantages of simple structure, convenient operation and high universality, improves the operation efficiency, and is particularly suitable for the application of modified clay powder.

Description

technical field [0001] The invention belongs to the technical field of harmful algal bloom control, in particular to a spraying device for eliminating harmful algal bloom. Background technique [0002] Microalgae-type harmful algal blooms are also called "water blooms" when they appear in rivers and lakes, and they are also called "red tides" when they appear in estuaries and offshore seas. Or abnormal water color caused by abnormal proliferation or aggregation of several planktonic microalgae. In recent years, the phenomenon of harmful algal blooms has become an ecological disaster that seriously endangers water resources. It will not only endanger water-related production activities, but may also damage aquatic ecological security and endanger human health. In order to mitigate the impact of harmful algal blooms, practical control measures are urgently needed. [0003] Wet spraying is the most practical application method of modified clay so far, that is, when harmful al...
