[0002] In the winemaking industry, it is necessary to add special activated carbon to the wine. Special activated carbon for wine plays a vital role in the winemaking process. Specifically: First, in the production of low-alcohol liquor, due to the reduction of the alcohol content of the liquor, the solubility of higher fatty acid ethyl esters and higher fatty alcohols in the liquor decreases, making the wine milky and turbid. Therefore, it is necessary to add special activated carbon for wine to adsorb the precipitate, keep the low-alcohol liquor from losing gloss at low temperatures, and also maintain the flavor of the original liquor of the strong-flavor liquor well; second, special activated carbon for wine is used to remove turbidity and accelerate aging of the liquor, remove foreign odors at a shallow level, prevent turbidity of high-alcohol liquor at low temperatures, remove various pigments in the liquor, remove bitter substances in the liquor, and improve the taste; third, special activated carbon for wine accelerates the aging and maturation of liquor.

[0003] Currently, the main way to add activated carbon is to manually or mechanically pour the activated carbon directly into the wine tank containing wine. However, due to the powdery structure of activated carbon, it is easy to produce floating dust during the pouring process, which seriously pollutes the surrounding environment. In addition, the direct pouring method results in a poor mixing effect of activated carbon and wine.

[0004] Therefore, people are in urgent need of a negative pressure powder filling device with good powder-liquid mixing effect and good environmental protection effect. Summary of the invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model aims to provide a negative pressure powder filling device to solve the problems existing in the prior art. Negative pressure is generated through a venturi pipeline to suck powder into a flowing liquid, thereby improving the powder-liquid mixing effect and the environmental protection effect.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Please refer to Figures 1-2As shown, a negative pressure powder filling device is provided, comprising a liquid tank 1 containing liquid, a powder box 2 containing powder and a mixing mechanism. When applied to the winemaking industry, the liquid tank 1 contains wine, the powder box 2 contains activated carbon specially used for wine, the mixing structure comprises a liquid pipeline 3, a powder pipeline 4, a venturi pipeline 5 and an output pipeline 6, a delivery pump 7 is arranged on the liquid pipeline 3, one end of the liquid pipeline 3 is connected to the liquid tank 1, and the other end is connected to the nozzle of the contraction section 8 of the venturi pipeline 5, one end of the powder pipeline 4 is connected to the powder box 2, and the other end is connected to the throat section 9 of the venturi pipeline 5, and one end of the output pipeline 6 is connected to the diffusion section 8 of the venturi pipeline 5. 10 is connected to the pipe mouth, and the other end is connected to the liquid tank 1. The working principle of the device is: the liquid in the liquid tank 1 is pumped out and supplied to the Venturi pipe 5 through the delivery pump 7. During the flow of the liquid in the Venturi pipe 5, based on the Venturi principle, the flow velocity of the fluid is accelerated at the throat with a smaller diameter, and a negative pressure will be generated at the throat section 9. The negative pressure will attract the powder in the powder box 2 through the powder pipe 4. The attracted powder enters the throat section 9 through the powder pipe 4 and mixes with the liquid. Compared with pouring the powder directly into the liquid tank 1, the floating dust generated during the pouring process is reduced, the environmental protection effect is improved, and the flow of the liquid will improve the mixing effect with the powder.

[0029] An annular opening 11 is provided on the throat section 9, and a connecting pipe section 12 is provided on the outer periphery of the contraction section 8 of the Venturi pipe 5. An annular cavity is formed between the connecting pipe section 12 and the contraction section 8. The annular cavity is connected to the annular opening 11 in a directional manner. The powder pipeline 4 is connected to the annular cavity. Negative pressure is reflected in the annular cavity through the annular opening 11. The powder enters the throat section 9 through the powder pipeline 4 and the annular opening 11 of the annular cavity. In the process of entering the throat section 9, the powder enters from the circumferential direction. Compared with entering from a single opening opened on one side, the powder can improve the uniformity of the powder when entering the throat section 9, thereby improving the mixing effect of the liquid and the powder.

[0030] In order to prevent the liquid in the Venturi pipeline 5 from entering the powder pipeline 4, a connecting pipe section 12 is provided, which includes a constant diameter pipe 13 and a reducing pipe 14 with a gradually decreasing inner diameter. The large diameter section of the reducing pipe 14 is connected to one end of the constant diameter pipe 13, and the reducing pipe 14 and the constant diameter pipe 13 are an integral structure. The end of the constant diameter pipe 13 away from the reducing pipe 14 is sealed with the contraction section 8 or the liquid pipeline 3, and the end of the reducing pipe 14 away from the constant diameter pipe 13 is sealed with the outer peripheral wall of the throat. The interface connecting the annular cavity and the powder pipeline 4 can be provided on the constant diameter pipe 13; the Venturi pipeline 5 and the connecting pipe section 12 can be integrally formed to achieve sealing at the connection. When a non-integral formed structure is selected, the two can be sealed and connected by welding.

[0031] The venturi pipe 5 and the connecting pipe section 12 can be produced as separate parts.

[0032] The connection mode of the venturi pipeline 5 with the liquid pipeline 3, the powder pipeline 4 and the output pipeline 6 can all be flange connection.

[0033] In order to facilitate the replenishment of the powder in the powder box 2, a feeding port 15 is provided on the top of the powder box 2. The external port of the feeding port 15 is a flared structure, which makes it more convenient for the staff to load the powder.

[0034] On the basis of setting the feeding port 15, a dust suction pipeline 16 is arranged on the powder box 2, and the air inlet of the dust suction pipeline 16 is located in the powder box 2, and the air inlet of the dust suction pipeline 16 is arranged close to the feeding port 15, and the air outlet of the dust suction pipeline 16 is connected with the powder pipeline 4. A first opening and closing valve 17 is arranged on the dust suction pipeline 16. By opening the first opening and closing valve 17 and the conveying pump 7, the negative pressure in the powder pipeline 4 will generate suction from the air inlet of the dust suction pipeline 16, which can absorb the floating dust generated in the process of feeding into the powder box 2, thereby improving the environmental protection effect.

[0035] A second on-off valve 18 is provided between the connection between the powder pipeline 4 and the dust suction pipeline 16 and the feed port of the powder pipeline 4 . The position where the suction force of the powder pipeline 4 is generated can be regulated by regulating the switches of the first on-off valve 17 and the second on-off valve 18 .

[0036] The first on-off valve 17 and the second on-off valve 18 can be manual valves or electric valves.

[0037] The bottom of the inner cavity of the powder box 2 is in an inverted cone shape, and the feed port of the powder pipeline 4 is arranged close to the bottom of the inner cavity of the powder box 2, so that the powder pipeline 4 can absorb the powder in the powder box 2 as cleanly as possible to avoid powder waste.

[0038] The liquid outlet of the output pipeline 6 is set higher than the maximum liquid level of the liquid tank 1. When the fluid in the output pipeline 6 flows back into the liquid tank 1, it will move downward under the influence of its own gravity to impact the liquid in the liquid tank 1. The impact can further improve the mixing effect of the powder and the liquid.

[0039] The liquid inlet of the liquid pipeline 3 is located at the bottom of the inner cavity of the liquid tank 1, so that the liquid in the entire liquid tank 1 is in a state that can be extracted, thereby improving the fluidity of the liquid in the liquid tank 1 and avoiding the problem that when the liquid inlet of the liquid pipeline 3 is set in the middle of the inner cavity of the liquid tank 1, the fluidity of the lower layer of liquid is poor, thereby reducing the mixing effect of the liquid and powder.

[0040] During actual use, the delivery pump 7 is started and the second on-off valve 18 is opened. The delivery pump 7 pumps the liquid in the liquid tank 1 to the venturi pipe 5. The negative pressure generated by the venturi pipe 5 attracts the powder in the powder box 2 through the powder pipe 4 to enter the venturi pipe 5 and mix with the flowing liquid. The mixed fluid is returned to the liquid tank 1 through the output pipe 6. The amount of powder in the powder box 2 can be controlled to achieve the amount of powder added to the liquid tank 1, that is, a certain amount of powder is added to the powder box 2. After continuously starting the delivery pump 7 and the second on-off valve 18 for a period of time, the powder in the powder box 2 is absorbed cleanly, and the quantitative addition of the powder in the liquid tank 1 is completed.

[0041] Adaptive changes made according to actual needs are all within the protection scope of this utility model.
