As shown in fig. 1-2, the integrated vertical tobacco shred recycling and wind pressure adjusting device comprises a collecting cylinder 1, an air inlet pipe 2 and an air outlet pipe 3 which are used for connecting a wind power branch pipe of a cigarette making machine are coaxially arranged in the collecting cylinder 1, the air inlet pipe 2 is positioned below the air outlet pipe 3, a spiral guide plate 2a is arranged in the air inlet pipe 2 along the axis direction of the air inlet pipe, the distance between the air inlet pipe 2 and the air outlet pipe 3 is enough for tobacco shreds to be thrown to the inner wall of the collecting cylinder 1 under the action of centrifugal force after being discharged from the top end of the air inlet pipe 2, a material baffle plate 4 used for blocking the tobacco shreds from moving upwards is annularly arranged between the outer wall surface of the air outlet pipe 3 and the inner wall surface of the collecting cylinder 2, a butterfly valve 5 used for adjusting the wind pressure is arranged in the air outlet pipe 3, a tobacco shred collecting hopper 6 used for collecting.

The vertical tobacco shred recycling and wind pressure adjusting integrated device provided by the embodiment is connected to the branch pipe of the cigarette making machine, after the air current with the tobacco shreds enters the air inlet pipe 2, the air current flows upwards in a spiral mode and is discharged from the top end of the air inlet pipe 2, at the moment, the tobacco shreds are thrown to the inner wall of the collecting cylinder 1 under the action of centrifugal force and tightly attached to the inner wall of the collecting cylinder 1 to move upwards, the speed of the upward movement of the tobacco shreds naturally drops to zero or drops to zero due to the blocking of the material blocking plate 4, the tobacco shreds settle downwards and drop to the material collecting hopper 6 to be collected, and the air can upwards enter the exhaust pipe 3 under the action of negative pressure to flow into the rear section of the wind power branch pipe, so that the tobacco shreds are separated and recycled.

In this embodiment, the butterfly valve 5 specifically includes a valve seat 5a and a valve plate 5b connected in the valve seat 5a, the opening of the valve can be adjusted by adjusting the valve plate 5b to rotate, two flow distribution plates 5c are disposed on one end surface of the valve plate 5b, two flow distribution plates 5c are symmetrically disposed on the other end surface, a plurality of through holes 5d are disposed on the flow distribution plates 5c, wherein the flow distribution plates 5c are semicircular, two rows of through holes 5d are disposed on the flow distribution plates 5c, the number of the through holes 5d is six, every three through holes 5d are arranged in a row on the flow distribution plate 5c at equal intervals, by designing the size, shape and position of the flow distribution plates 5c according to a certain variation law, the required butterfly valve 5d has good flow rate adjustment characteristics, so that the valve opening of the valve plate 5d is affected by the flow distribution plates 5c and the through holes 5d during adjustment, and then can directly act on the control to the valve flow regulation size for further trend linear proportional relation between the wind pressure size and the valve opening size.

For the butterfly valve 5 with the above structure, the present embodiment provides a set of test data to verify the proportional relationship between the valve opening and the flow coefficient, specifically, the test data is obtained by performing simulation calculation and experimental research with water as the fluid medium and is made as followsThe linear scale chart shown in fig. 3 is worth referring to the test data in view of the identity of water and air in the fluid mechanics law of motion. When fluid flows through the control valve body in a pipeline, both pressure and flow rate will change due to energy loss caused by friction of the fluid with the valve body. When fluid flows through the valve body, the pressure is controlled by

Is reduced to

And a pressure head loss calculation formula of the control valve can be deduced according to a fluid mechanics continuity equation and a Bernoulli equation:

=

（1）

where ρ is the fluid density, g is the gravitational acceleration, and Δ p is the differential pressure across the valve.

Meanwhile, since dynamic pressure is a cause of head loss, therefore,

can also be expressed as:

（2）

where ζ is the local resistance coefficient and V is the flow velocity.

The formula of the wind speed calculation can be obtained by integrating the formulas (1) and (2):

（3）

order to

For characterizing the flow rate characteristics of the valve body, may be calledIs the flow rate coefficient.

（4）

For a control valve, both the local drag coefficient ζ and the flow rate coefficient ψ are closely related to the valve opening, and in fact are functions of the valve opening: ψ = f (x), and x is the opening degree. Through a laboratory test platform, a series of data can be measured on the flow velocity and the pressure difference of the butterfly valve under different opening degrees, and the functional relation between the valve opening degree and the flow velocity coefficient is solved through a formula (4). The finally obtained figure 3 is a schematic diagram of the functional relationship between the valve opening x (0-100 degrees) and the resistance coefficient zeta, and as can be seen from the figure 3, the flow regulating characteristic curve of the butterfly valve has better linearity, and the higher the linearity is, the more beneficial to realizing the accurate control of the flow is, and the linear regulation of the flow can be realized even under the condition of large opening.

In addition, it should be noted that the butterfly valve 5 with the added flow distribution plate 5c cannot be applied to a directly connected branch pipe of a cigarette making machine alone, because the phenomenon of thread hanging is very easily generated on the flow distribution plate 5c, that is, the tobacco threads are very easily hung on the through hole 5d of the flow distribution plate 5c, and once the phenomenon of thread hanging occurs, a certain degree of blockage is caused, so that the linearity and the adjustment precision of the butterfly valve 5 are seriously affected.

In the present application, the butterfly valve 9a of the plug attachment machine mounted on the second branch pipe 9 is not modified, and the butterfly valve 9a of the plug attachment machine may be a conventional one having a common structure. Since the air lock valve 7 belongs to a material-air separating valve commonly used in the prior art, the invention of the present application is not described here, and thus the structure thereof will not be described in detail. In addition, the outlet of the air lock valve 7 can be connected with a discharge pipe 10 communicated with a cut tobacco feeding pipe of the cigarette making machine, so that the collected cut tobacco can be conveniently fed back to the cigarette making machine for continuous utilization.

The above embodiments are preferred implementations of the present invention, and the present invention can be implemented in other ways without departing from the spirit of the present invention.
