Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco dust removal equipment, specifically, it relates to a water-throwing impeller for dust reduction in tobacco workshops. Background Technology

[0002] In tobacco production workshops, especially in the tobacco processing workshop, a significant amount of smoke and dust is generated. This smoke and dust needs to be removed and treated promptly during the production process, and is controlled through dust removal equipment. Traditional solutions use filtration methods such as bag filters to reduce dust. However, the smoke and dust in tobacco is usually tobacco dust with a certain amount of grease. The filtration method of bag filters easily leads to the filter bags becoming dirty, difficult to clean, with a short maintenance time and a high scrap rate.

[0003] To address this, the industry has developed an improved solution that uses water curtain dust removal to absorb smoke and dust. Water curtain dust removal has many advantages. It can use particles formed by water mist to adsorb smoke and dust, and the subsequent treatment process only requires water treatment. This significantly reduces the complexity of post-treatment compared to smoke and dust treatment, and in particular, it solves the problem of the difficulty in cleaning the oily properties of smoke and dust to a certain extent.

[0004] However, the water-spraying impeller is the core component of water curtain facilities. Currently, the simplest water-spraying impeller uses a fan-type structure to spray water, but its ability to form water mist is limited. The core issue of current research is how to improve the water mist forming ability of the water-spraying impeller. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a water-throwing impeller for dust suppression in tobacco workshops that has high water-throwing efficiency and strong fogging capability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A water-spraying impeller for dust suppression in a tobacco workshop includes a main body, a shaft hole, a water distribution chamber, blades, and water-spraying protrusions.

[0008] The main body includes a base plate and a shaft portion protruding from the center of the base plate. The shaft hole is provided in the shaft portion. The water distribution chamber is arranged around the shaft hole to form an annular chamber with an open top. The inner area of ​​the base plate constitutes the bottom wall of the water distribution chamber. Several water-throwing holes are opened at the bottom of the outer wall of the water distribution chamber.

[0009] The blade is L-shaped overall, and its rear end is fixed to the outer wall of the annular chamber.

[0010] The bottom end of the blade is fixed to the outer area of ​​the base plate, and the outer side of the blade is arc-shaped.

[0011] The water-striking protrusion is provided on the outer upper surface of the base plate.

[0012] Furthermore, a water-throwing hole is formed on the outer wall of the annular chamber between each pair of adjacent blades.

[0013] Furthermore, a water-striking protrusion is provided on the upper surface of the outer end of the base plate between each pair of adjacent blades.

[0014] Furthermore, the water-splashing protrusion is pyramid-shaped, with a large base and a pointed top.

[0015] Furthermore, the blades are twisted in the same direction to form a propeller-like structure.

[0016] Furthermore, the outer circumferential surface of the base plate is densely covered with several oblique teeth.

[0017] Furthermore, the diameter of the base plate is 20-30cm, and the height of the shaft is 15-20cm.

[0018] Furthermore, oblique teeth are provided on the outer circumference of the base plate. These oblique teeth can further cut the flowing water to form a water mist.

[0019] The beneficial effects of this utility model are:

[0020] 1. This technical solution significantly changes the structural form of traditional water-throwing impellers. A water distribution chamber is added to the inner ring area, which evenly disperses the collected water in all directions before it is thrown out by the blades to form water mist. The overall shape of the blades is L-shaped with a base plate for support, making it difficult for water to flow away from below under the action of gravity. All the water can be thrown out to form mist. Even if a small amount of water fails to be thrown out by the impeller, it will be broken up again by the water-throwing protrusions on the outer side when it encounters them, forming water mist. The water atomization ability is greatly enhanced.

[0021] 2. This solution enhances the fogging capability of the water-spinning impeller by adding more fogging methods. Attached Figure Description

[0027] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0028] like Figures 1-3 As shown, this application discloses a water-throwing impeller for dust suppression in a tobacco workshop, comprising a main body 1, a shaft hole 2, a water distribution chamber 3, blades 4, and water-striking protrusions 5.

[0029] The main body 1 includes a base plate 11 and a shaft 12 protruding from the center of the base plate. The diameter of the base plate is 20-30cm and the height of the shaft is 15-20cm.

[0030] A shaft hole 2 is provided on the shaft part 12, and a water distribution cavity 3 is provided around the shaft hole 2 to form an annular cavity with an open top. The inner area of ​​the bottom plate constitutes the bottom wall of the water distribution cavity, and several water-throwing holes 6 are opened at the bottom of the outer wall of the water distribution cavity.

[0031] In this embodiment, the blade 4 is generally L-shaped, the rear end of the blade 4 is fixed to the outer wall of the annular chamber, the bottom end of the blade 4 is fixed to the outer area of ​​the base plate 11, and the outer side of the blade 4 is arc-shaped; the blade 4 is twisted in the same direction to form a propeller-like structure. Specifically, a water-throwing hole 6 is opened on the outer wall of the annular chamber between each pair of adjacent blades 4.

[0032] The water-striking protrusion 5 is provided on the upper surface of the outer end of the base plate 11. The water-striking protrusion is in the shape of a pyramid with a large bottom and a pointed top. One water-striking protrusion 5 is provided on the upper surface of the outer end of the base plate between each two adjacent leaves 4.

[0033] In this application, the outer circumferential surface of the base plate 11 is densely covered with a number of helical teeth 7.

[0034] Technical principle explanation:

[0035] Water flows into the water distribution chamber 3 from the top through pipes or other means. During the rotation of the water distribution chamber 3, the water flows from the water ejection hole 6 to the area where the blades are located. As the blades 4 rotate at high speed, the water is scattered and flung away to form atomized water, which is the main part of water mist formation.

[0036] Some of the water flows outward with the bottom plate 11 and is not dispersed by the blades 4. After encountering the water-splashing protrusions 5, it is dispersed to form atomized water.

[0037] Another portion of water, which was not dispersed by the water-splashing protrusion 5, continued to flow to the boundary of the bottom plate 11, where it was further cut by the oblique teeth 7 to form a water mist.

[0038] The implementation of multiple water mist generation methods has significantly improved the mist generation capacity and enhanced impeller performance.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
