Description

Technical Field

[0001] The utility model belongs to the field of tobacco, and specifically relates to a water-lifting, water-spinning and atomizing mechanism for tobacco dust removal, which is used in a silk-making workshop, a filter rod workshop and a dust removal workshop. Background Art

[0002] In the tobacco industry's silk-making workshops and filter rod workshops, a corresponding amount of dust is generated during the filter rod molding and tobacco leaf silk-making processes. These dusts are small in size and easy to disperse, posing a flammable and explosive safety risk in the workshop environment.

[0003] Currently, this type of dust is primarily collected using traditional dust removal equipment such as bag filters and cyclones. However, these equipment require regular cleaning, and due to the relatively large amount of dust, replacement frequency is very high, resulting in high overall processing costs. Furthermore, the flying fibers generated by cigarette filter rod production can further impact worker health and induce respiratory illnesses. To address this, a new type of dust removal equipment has been developed that uses water mist adsorption. This equipment meets dust removal requirements with virtually no consumables, requiring only wastewater reprocessing. This addresses dust removal, explosion prevention, and safety issues in workshops.

[0004] This type of equipment utilizes a wide range of water mist shaping mechanisms, most often in the form of sprinklers. However, these nozzles have limitations in certain specific piping configurations. For example, in a closed vertical space, where water atomization requires the water to be sprayed from the center outward, traditional sprinkler systems are limited, effectively spraying from the top downward. Given these challenges, designing an atomization mechanism capable of both lifting and shedding water is an urgent need. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies of the existing technology and thus provide a water-lifting and water-stripping atomizing mechanism for tobacco dust removal which can complete the functions of water lifting and water stripping.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A water-lifting and water-throwing atomizing mechanism for tobacco dust removal comprises a spiral lifting channel, a water-throwing impeller and a water storage chamber;

[0008] The spiral lifting channel is arranged below the water storage chamber and is connected to the water storage chamber, and is used to deliver water to the water storage chamber by spiral conveying;

[0009] The water storage chamber is a water storage tray structure with an open top;

[0010] The water-repelling impeller is installed in the water storage chamber, the highest point of the blade of the water-repelling impeller is higher than the upper end boundary of the water storage chamber, and the lowest point of the blade of the water-repelling impeller is lower than the upper end boundary of the water storage chamber.

[0011] Preferably, the water-spraying impeller has a rotating shaft, and the rotating shaft is driven to rotate by a transmission motor and a transmission shaft.

[0012] Preferably, the transmission motor and the transmission shaft are installed in the space above the water-spraying impeller.

[0013] Preferably, the spiral lifting channel includes a vertically arranged circular channel and a spiral track groove installed in the circular channel, a drive shaft is provided at the upper end of the spiral track groove, and the drive shaft is coaxially fixed with the rotating shaft of the water-spraying impeller.

[0014] Preferably, the blades of the water-spraying impeller are straight-edge blades distributed radially around the rotation axis.

[0015] Preferably, the blades of the water-spraying impeller are curved blades distributed radially around the rotation axis.

[0016] Preferably, the angle between the blades of the water-spraying impeller is 15°-30°.

[0017] Preferably, the water-spraying impeller is made of metal.

[0018] Preferably, the water storage chamber is made of metal, and the bottom end of the water storage chamber is a flat bottom.

[0019] Preferably, the bottom end of the spiral track groove is arranged beyond the bottom end of the circular channel.

[0020] The beneficial effects of the utility model are:

[0021] This technical solution first uses a spiral lifting method to lift the water source below into the water storage chamber through rapid rotation, and then uses the water-spraying impeller installed above to spread the water stored in the water storage chamber outward at high speed, eventually forming mist water that radiates from the center to the surrounding areas. Generally speaking, the particle size of this type of mist water is relatively large, and it is generally used in the primary treatment link of multi-stage water treatment facilities. It can absorb larger dust particles and achieve dust reduction of large particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the present invention is 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 the present invention, and cannot be interpreted as limiting the technical solution of the present invention.

[0028] like Figure 1-Figure 3 As shown, the present application provides a water-lifting and water-throwing atomizing mechanism for tobacco dust removal, comprising a spiral lifting channel 1, a water-throwing impeller 2 and a water storage chamber 3. The device is usually installed in a vertical smoke dust channel 4, and is used to throw water from the center position of the vertical smoke dust channel 4 to the surrounding areas to form an umbrella-shaped water curtain, performing the first-level adsorption and dust reduction treatment on the dust-laden airflow, removing larger particles, and relieving pressure on subsequent secondary or even tertiary dust reduction facilities.

[0029] Specifically, in this embodiment, the spiral lifting channel 1 is arranged below the water storage chamber 3 and is connected to the water storage chamber 3, and is used to deliver water to the water storage chamber 3 by spiral conveying. The spiral lifting channel 1 includes a vertically arranged circular channel 11 and a spiral track groove 12 installed in the circular channel 11. A drive shaft is provided at the upper end of the spiral track groove 12. The drive shaft is coaxially fixed with the rotating shaft of the water-throwing impeller 2 and rotates synchronously with the water-throwing impeller 2 at high speed. The bottom end of the spiral track groove 12 is arranged beyond the bottom end of the circular channel 11 so as to better deliver water into the circular channel 11.

[0030] In the present application, the water storage chamber 3 is a water storage tray structure with an open top. In this embodiment, the water storage chamber 3 is made of metal, and the bottom of the water storage chamber 3 is a flat bottom.

[0031] In the present application, the water-throwing impeller 2 is installed in the water storage chamber 3, the highest point of the blades of the water-throwing impeller 2 is higher than the upper boundary of the water storage chamber 3, and the lowest point of the blades of the water-throwing impeller 2 is lower than the upper boundary of the water storage chamber 3. Specifically, in the present embodiment, the water-throwing impeller 2 has a rotating shaft 21, and the rotating shaft 21 is driven to rotate by a transmission motor and a transmission shaft. The transmission motor and the transmission shaft are installed in the space above the water-throwing impeller 2. Usually, the transmission motor will be installed on the outside at the end of the vertical channel to prevent water or dust from entering the motor and affecting the normal operation of the motor. It enters the vertical channel through the transmission shaft and is connected to the rotating shaft 21 of the water-throwing impeller 2. The overall height should not be too high. If the design height of the vertical channel is high, the transmission motor can also be installed inside the vertical channel after being waterproofed; if there are multi-stage water mist dust removal facilities above, the transmission shafts of each dust removal facility can also be linked by coupling drive.

[0032] In this embodiment, the blades of the water-throwing impeller are straight-edged blades radially distributed around the rotating axis, which have better water-throwing ability. The angle between the blades of the water-throwing impeller is 15°-30°, the density is relatively high, and the material of the water-throwing impeller is metal, which is not easy to deform or damage.

[0033] In other embodiments, the blades of the water-spraying impeller are curved blades distributed radially around the rotation axis. The curved blades can be used to achieve the design of some special water mist shapes.

[0034] Working principle:

[0035] like Figure 3 As shown, the dust-laden gas is introduced into the vertical smoke channel 4 from the left pipeline and flows from bottom to top. The vertical smoke channel 4 itself is used as a dust removal method. In the process of the smoke moving from bottom to top, the larger particulate matter mixed in the airflow will be separated under the action of its own gravity, but due to the boosting effect of the airflow, the separation capacity is limited.

[0036] This solution is essentially to improve the dust reduction effect of large particles during the vertical airflow lifting process. An external water pipe is connected below the vertical smoke and dust channel 4 to supply water to the bottom. On the one hand, it is used to receive the falling large particles. On the other hand, water mist is formed through the spiral lifting channel 1. In the process of the water mist being thrown from the center to the surroundings, a water curtain formed by small particles of water droplets is formed, which can cover the entire vertical smoke and dust channel 4. After the large particles passing through are adsorbed by the water droplets, the gravity increases, and then they fall and separate, completing the primary separation task of the dust-laden gas.

[0037] Subsequent fine particulate matter can be treated through secondary or tertiary water mist dust removal or other dust removal methods.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
