Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings. Only this statement, the utility model discloses the upper and lower, left and right, preceding, back, inside and outside etc. position words that appear or will appear in the text only use the utility model discloses an attached drawing is the benchmark, and it is not right the utility model discloses a concrete restriction.

The invention is further described with reference to the accompanying drawings and the detailed description below:

referring to fig. 1-3, a liquid-powder mixer includes a water inlet cavity 1, a powder inlet joint 2 and a mixing pipe 3, a water inlet pipe 10 is disposed on a side portion of the water inlet cavity 1, the mixing pipe 3 is in interference connection with a lower portion of the water inlet cavity 1, the powder inlet joint 2 is in a tubular structure, a powder outlet cavity 21 is disposed on a lower portion of the powder inlet joint 2, after the powder inlet joint 2 is inserted into the water inlet cavity 1, the powder outlet cavity 21 extends to an inner side of the water inlet cavity 1 opposite to the lower portion of the water inlet pipe 10, a water inlet gap 22 is formed between an outer side wall of the powder outlet cavity 21 and an inner side wall of the water inlet cavity 1, and when water flows into the water inlet gap 22 and the mixing pipe 3 from the water inlet pipe 10, an overflow section is reduced.

In this embodiment, preferably, the cross section of the powder discharging cavity 21 is an inverted isosceles trapezoid structure, and the water inlet cavity 1 and the corresponding inner side structure of the powder discharging cavity are matched with the structure of the powder discharging cavity 21 to form the water inlet gap 22.

In order to facilitate the occurrence of blockage and the like in the powder inlet joint 2, in this embodiment, referring to fig. 4, the powder inlet joint 2 is in threaded connection with the inner side of the water inlet cavity 1, the upper portion of the powder inlet joint 2 is provided with a rotating body 20, the rotating body 20 is in a prism structure, the rotating body 20 is arranged on the outer side of the water inlet cavity 1, and the powder inlet joint 2 can be disassembled by unscrewing the rotating body 20, so that the maintenance is facilitated.

In order to improve the sealing performance of the liquid-powder mixer, in the present embodiment, a sealing ring 11 is disposed between the powder inlet joint 2 and the threaded end of the water inlet cavity 1.

In the embodiment, the powder inlet joint 2, the water inlet cavity 1 and the mixing pipe 3 are preferably made of PVC material or stainless steel material, and the PVC material can make the weight light, reduce the cost and facilitate the processing; and the stainless steel material is not easy to damage, and the service life is prolonged.

In this embodiment, as preferred, mixing tube 3 and intake chamber 1 can be dismantled and be connected, and its connection mode that can dismantle can adopt threaded connection or joint.

In practical application, the powder feeding connector 2 upper portion passes through the retention aid feed bin of hose intercommunication powder structure, and the external rivers that have certain pressure of intake chamber 1, water pressure when rivers can not satisfy, then can adopt the force (forcing) pump in order to improve intake pressure, after the rivers that take certain pressure pass through inlet tube 10 and get into intake chamber 1, because set up into water clearance 22 between powder outlet chamber 21 and the intake chamber 1, rivers pass through into water clearance 22 after getting into inlet tube 10, the section of overflowing reduces, according to the venturi effect, when the section of overflowing through reducing, the phenomenon of velocity of flow increase appears in the fluid, its velocity of flow and the section of overflowing are the inverse ratio. On the other hand, since the increase in flow velocity is accompanied by a decrease in fluid pressure as known from bernoulli's law, a low pressure is generated in the vicinity of a fluid flowing at a high speed, and adsorption occurs. Therefore, tap water entering the water inlet cavity 1 has certain pressure and flow velocity, and flows through the water inlet gap 22 at certain pressure and flow velocity, because the flow cross section is reduced when passing through the water inlet gap 22, high-speed jet flow can be formed, and vacuum is generated, and low pressure can be generated near the fluid flowing at high speed, so that adsorption is generated, the powdery retention aid is sucked into the powder inlet joint 2 under the vacuum action, and is fully mixed with high-speed water flow in the mixing pipe 3 through the powder outlet cavity 21, in practice, the mixing pipe 3 is directly communicated with a stirring tank for storing the retention aid, and under the normal condition, the height of the liquid-powder mixer is higher than that of a storage bin for storing the retention aid, so that the liquid-powder mixer can suck dry powder at the lower part of the ground into the top of the tank, and achieves the purpose of fully mixing and dissolving the dry powder with liquid.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
