detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

In describing the present invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical" , "horizontal", "top", "bottom", "inner", "outer" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the utility model, rather than Any indication or implication that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation should not be construed as limiting the invention.

As shown in Figure 1, a flocculant additive includes a pressure reducing valve 1, a diverter three-way valve 2, a sudden expansion tube 3, a liquid-containing capsule 4, a gradual expansion tube 5, an inner shrinkage tube 6 and an outer shrinkage tube 7, The pressure reducing valve 1 is arranged at the left end of the expanding tube 5, the inner shrinking tube 6 is located inside the expanding tube 5, the outer shrinking tube 7 is connected to the right end of the expanding tube 5, and the sudden expanding tube 3 is provided with Two interfaces, one of which is connected to the diverter three-way valve 2 between the pressure reducing valve 1 and the inner shrinkage tube 6, and an air valve is provided on the pipeline of the interface, and the other interface is connected to the inner shrinkage tube 6 and the outer shrinkage tube Between the tubes 7, and the interface is located at the mouth of the shrinking tube 6, the sudden expansion tube 3 is provided with a liquid-containing capsule 4, which is convenient for controlling the ratio of the medicament to water, and can make the water and the medicament mix more uniformly, optimizing Flocculation effect.

Further, the liquid-containing capsule 4 is in the shape of an ellipsoid, so that the volume of the liquid-containing capsule 4 is larger.

Further, the sudden expansion tube 3 , the gradual expansion tube 5 , the inner shrinkage tube 6 and the outer shrinkage tube 7 are all made of ABS plastic tubes, which have certain shaping and corrosion resistance.

The working principle of the utility model is as follows: as shown in Figure 1, a flocculant adding tank is connected to the water inlet pipeline. In order to ensure pressure balance and smooth addition of additives, The tank is connected to the pipeline through two interfaces. After the medicine flows into the water inlet pipeline, it passes through a section of expander 5 to make it evenly mixed with the water flow, then flows out through the reducer, and finally connects to the mixing system. The size of the tank can be selected according to the amount of flocculant, and different models can be selected. The whole device is made of stainless steel, relying on high-pressure static pressure water to form suitable pressure water after passing through the pressure reducing valve. Continuing the movement, a certain negative pressure zone is generated by the front spray of the reducer. The flocculant enters the main pipe under the action of gravity and negative pressure, and then passes through the expander 5 to generate a vortex, fully mix the flocculant with water, and form the required flocculant under the action of pressure.

Based on the above, the utility model has the following advantages: the utility model calculates the water flow rate of the water inlet pipeline and the flow rate of the dust suppression flocculant addition pipeline during the use process according to the resistance along the process, local resistance and energy loss. The device is easy to use and has good effect. It is convenient to control the ratio of chemical agent and water, which can make water and chemical agent mix more uniformly and optimize the flocculation effect.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
