Description

Technical Field

[0001] The utility model relates to material mixing equipment, in particular to a water and gas supply device for water-powder mixing equipment. Background Art

[0002] The applicant disclosed an air purification ball, a method for preparing an air purification ball and an air purifier in the patent application number 201811102363.0, wherein the air purification ball is made by mixing lime powder, heavy calcium powder, zeolite powder, tourmaline powder, talcum powder, white cement, barite, diatomaceous earth and other powders, and then prepared into small balls. The functional materials added to the product can continuously release negative oxygen ions into the air, playing a role in refreshing the air, so the applicant also calls it a negative oxygen ion ball.

[0003] When preparing the above-mentioned negative oxygen ion balls, various powders need to be mixed together and then mixed evenly with a little water for subsequent granulation. In order to make the water-powder mixing more uniform and the ball shape more uniform, the applicant designed a device in the cyclone channel that uses the rising cyclone to drive the powder to disperse and sprays atomized water on the dispersed powder to achieve water-powder mixing. There is no water supply and air supply device designed to match it in the prior art.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The utility model aims to address the deficiencies of the prior art and thus provide a water-gas supply device for water-powder mixing equipment which can be matched with a swirl channel and whose outer wall can guide powder dispersion and airflow to bring up powder more easily.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a water gas supply device for water-powder mixing equipment, including a cylinder, an air duct axially extending through the cylinder and a plurality of atomizing nozzles, the cylinder including a cylindrical section, a thin waist section and an outward expansion port connected in sequence from top to bottom, the outer wall of the thin waist section is an arc shape concave inward, the outer wall of the outward expansion port is conical, the shape of the air duct is consistent with the outer shape of the cylinder, and the plurality of atomizing nozzles are evenly arranged on the middle outer wall of the cylindrical section.

[0007] Based on the above, the curvature of the outer wall of the thin waist section gradually increases from the top end to the bottom end.

[0008] Based on the above, the length of the cylindrical section is not less than 2 / 3 of the total length of the cylinder.

[0009] Based on the above, a water supply pipe for supplying water to the plurality of atomizing nozzles is attached to the inner wall of the air duct, and the top end of the water supply pipe extends out of the top of the cylinder.

[0010] Based on the above, a total of six atomizing nozzles are provided, and the six atomizing nozzles are arranged on the same cross section of the cylindrical segment.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the barrel in the utility model is used to be inserted in the swirl channel, and the top of the cylindrical section extends to be flush with the exhaust port of the swirl channel. During exhaust, the airflow passes through the air duct and enters the swirl channel from the outward expansion port to form an upward rolling swirl, and the powder is sprayed from the side onto the outer wall of the thin waist section, splashed obliquely upward, and brought into the swirl channel by the swirl, and evenly mixed with the water mist sprayed from the atomizing nozzle. The weight of the wetted powder increases and it falls back toward the bottom of the swirl channel. It has the advantages of being able to match the swirl channel, the outer wall being able to guide the powder to disperse, and the airflow being able to more easily bring up the powder.

[0012] Furthermore, the water supply pipe is arranged on the inner wall of the air duct without occupying additional space, making the structure more compact. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0018] like Figure 1 and Figure 2As shown, a water-gas supply device for water-powder mixing equipment comprises a cylinder 1, an air duct 2 axially penetrating the cylinder 1 and six atomizing nozzles 3; the cylinder 1 comprises a cylindrical section 11, a thin waist section 12 and an outward expansion port 13 connected in sequence from top to bottom, the outer wall of the thin waist section 12 is in an arc shape concave inwards, and its curvature gradually increases from the top to the bottom, so as to better roll the powder upward; the outer wall of the outward expansion port 13 is conical, the shape of the air duct 2 is consistent with the shape of the cylinder 1, and the six atomizing nozzles 3 are evenly arranged on the outer wall of the same cross section in the middle of the cylindrical section 11.

[0019] When used specifically, Figure 3 As shown, the barrel 1 is inserted at the central axis of the swirl channel 4, and the top of the cylindrical section 11 is extended to be flush with the exhaust port 5 of the swirl channel 4. During exhaust, the airflow passes through the air duct 2 and enters the swirl channel 4 from the outward expansion port 13 to form an upward rolling swirl, and the powder is sprayed from the side onto the outer wall of the thin waist section 12, splashed obliquely upward, and is brought into the swirl channel 4 by the swirl to diffuse, and is evenly mixed with the water mist sprayed from the atomizing nozzle 3. The weight of the wetted powder increases and it falls back to the bottom of the swirl channel 4.

[0020] In order to ensure that the swirl path has a suitable stroke, the length of the cylindrical section 11 is not less than 2 / 3 of the total length of the cylinder 1 , and in this embodiment is about 5 / 7 of the total length of the cylinder 1 .

[0021] In order to avoid the water supply pipeline from occupying extra space, a water supply pipe 6 for supplying water to the six atomizing nozzles 3 is attached to the inner wall of the air duct 2, and the top end of the water supply pipe 6 extends out of the top of the cylinder 1 to be connected to an external water source.
