Description

Centrifugal impeller

Technical Field

The utility model relates to the field of cigarette production, in particular to a centrifugal impeller.

Background

The tobacco cutting machine is an essential device in the tobacco production process, is used for cutting tobacco raw materials into shreds to form cut tobacco, and further processes the cut tobacco in subsequent processes, and can generate a large amount of smoke dust in the shredding process, and tiny particulate matters such as scraps in the smoke dust can influence the purity of the cut tobacco, so that negative pressure air can be generally configured to suck the cut tobacco, but the dust-containing gas cannot be directly discharged and needs to be filtered.

The commonly used filtering equipment is cloth bag dust removal, a filter element needs to be replaced regularly, the replacement cost is high, and the cyclone dust collector has poor effect on the light impurities and high cost.

Currently, there is a new type of the present invention with application number CN202110495646.1, entitled: the centrifugal washing sterilizing air purifier has one purifying module with centrifugal impeller as core element and excellent purifying effect, but the single module has limited purifying energy, so that several modules need to be superposed for use together.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a centrifugal impeller, includes axle sleeve and blade, the blade is circular-arcly and uses the axle sleeve to be the array of equidistance such as the centre of a circle, the blade includes first arc board, second arc board and connecting rib, vertical parallel arrangement is followed with the second arc board to first arc board, connecting rib is used for connecting first arc board and second arc board.

Basically, the connecting ribs are arc-shaped structures inclined along the rotation direction of the centrifugal impeller.

Basically, the first arc plate is located the second arc plate top, the width of first arc plate is greater than the second arc plate.

Basically, a plurality of ribs which are horizontally arranged and are parallel to each other are arranged on the peripheral surface of the first arc plate.

Basically, a plurality of ribs which are horizontally arranged and are parallel to each other are arranged on the peripheral surface of the second arc plate.

Basically, the top of first arc board is provided with the first portion of following of buckling to the oblique top in inboard.

And a second edge portion bent obliquely outward and downward is arranged below the second arc plate.

Basically, the first arc plate and the second arc plate are connected together at two ends to form an integral structure.

Compared with the prior art, the impeller has substantive characteristics and progress, and particularly, the impeller improves the blades into the structures of the first arc plate, the second arc plate and the connecting ribs on the basis of the original impeller, so that the structural strength of the blades is improved, the water throwing efficiency of the blades is improved, and particularly the connecting ribs can fully break up water drops under the condition of high-speed rotation.

The protruding structures of the ribs, the connecting ribs and the like on the blades can promote the formation of water mist in the process of high-speed rotation.

The width broad of first arc board, the width of second arc board is narrower, is guaranteeing structural strength's basis, has reduced the resistance of rotation in-process.

The second edge part is used for receiving water mist from the lower part, and the first edge part is used for preventing water from running off from the upper part and limiting the water mist to be thrown out from the periphery to the maximum extent.

Detailed Description

The technical solution of the present invention is further described in detail by the following embodiments.

As shown in fig. 1 and 2, a centrifugal impeller comprises an impeller sleeve 1 and blades 2, wherein the blades 2 are arc-shaped and are arrayed at equal angles by taking the impeller sleeve as a circle center, the blades comprise a first arc plate 2-1, a second arc plate 2-2 and connecting ribs 2-3, the first arc plate 2-1 and the second arc plate 2-2 are longitudinally arranged in parallel, the connecting ribs 2-3 are used for connecting the first arc plate 2-1 and the second arc plate 2-2, the connecting ribs 2-3 are inclined along the rotation direction of the centrifugal impeller, the two arc plates can enhance the water throwing capacity, the connecting ribs 2-3 can enhance the structural strength of a guard plate, and on the other hand, the water drops can be scattered in an auxiliary manner.

The first arc plate 2-1 is located above the second arc plate 2-2, the width of the first arc plate 2-1 is larger than that of the second arc plate 2-2, a plurality of ribs 2-4 which are horizontally arranged and parallel to each other are arranged on the outer peripheral surface of the first arc plate 2-1, the first arc plate plays a main water throwing role, and the ribs 2-4 can strengthen the structural strength of the arc plate, prevent the arc plate from deforming at a high speed, increase the surface area and improve the water throwing area.

A second edge part 2-5 bent towards the outer oblique lower side is arranged below the second arc plate 2-2, a first edge part 2-6 bent towards the inner oblique upper side is arranged above the first arc plate, the second edge part 2-5 is used for receiving water mist from the lower side, and the first edge part 2-6 is used for preventing water from running off from the upper side and limiting the water mist to be thrown out from the periphery to the maximum extent.

Meanwhile, when the water throwing capacity needs to be improved, the two centrifugal impellers can be used in a splicing mode, the second edge part 2-5 of the upper impeller is placed on the inner side of the first edge part 2-6 of the lower impeller to form a channel, and water mist can circulate between the two impellers.
