Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings for the convenience of the skilled person.
As shown in fig. 1-3, the device for reducing the number of tobacco sheets steamed during threshing, redrying and moistening comprises a steam chamber 3, a nozzle frame 4, a sliding sleeve 5, a water outlet pipe 7 and a spiral nozzle 8, wherein two sides of the steam chamber 3 are respectively butted with a hot air pipe 1 and a leaf moistening roller 2, direct-injection steam is injected into the chamber fed by the hot air pipe 1, tobacco leaves are heated and humidified under the action of a steam duplex nozzle in the roller, because the leaf moistening effect is improved, the nozzle frame 4 is arranged in the steam chamber 3 along the direction of hot air wind, the sliding sleeve 5 with adjustable position is arranged on the nozzle frame 4, the water outlet pipe 7 is arranged on the sliding sleeve 5, because horizontal injection is changed into top downward-flushing injection, water and steam pipelines used for injection need to extend into the roller, in order to avoid tobacco leaves in the roller hanging on the pipelines and the nozzles, the water and steam pipelines extending into the roller are wrapped by arc-shaped bent pipes to form the water outlet pipe 7, the length of the arc-shaped bent pipe is determined according to the size of the leaf moistening roller 2, the arc-shaped bent pipe is arranged above the leaf moistening roller 2, tobacco leaves are thrown away by the roller in the 11 o' clock direction in the roller, a nozzle in the arc-shaped bent pipe faces the throwing surface, a water vapor mist layer is fully contacted with the maximum area of a material throwing layer in the roller, and the leaf moistening effect is enhanced.
Install spiral nozzle 8 on outlet pipe 7, spiral nozzle 8 stress distribution is reasonable, sprays and distributes more evenly, can improve fine steam fog, so with steam spiral nozzle 8 spray the back, just can replace completely with directly spout steam, steam duplex nozzle and directly spout the steam injection in the cavity that hot-blast main 1 said sent into, the mode that steam duplex nozzle sprays, cancelled directly spout steam, simplified system architecture. The spiral nozzle 8 corresponds to the throwing surface of the leaf moistening roller 2, and the installation angle of the spiral nozzle 8 is 120 degrees. In the specific implementation process, the distance from the outer wall of the leaf moistening roller 2 to the tobacco leaf throwing surface in the roller is measured, the distance from the 120-degree spraying surface of the spiral nozzle 8 to the tangent point of the tobacco leaf throwing surface in the roller and the horizontal included angle of the tangent are measured, and the height position of the spiral nozzle 8 and the horizontal distance from the spiral nozzle 8 to the tangent point of the tobacco leaf throwing surface are calculated by utilizing a trigonometric function. Meanwhile, according to the distance from the outer wall of the leaf moistening roller 2 to the tobacco leaf throwing surface in the roller and the horizontal distance from the spiral nozzle 8 to the tangent point of the tobacco leaf throwing surface, the horizontal distance of the water outlet pipe 7 is calculated, and meanwhile, the arc-shaped water outlet pipe 7 is manufactured. And determining the origin of coordinates of the nozzle rack 4 by utilizing the height position of the spiral nozzle 8 and the height distance of the arc-shaped bent pipe in the first step and combining a horizontal line that a 120-degree spray surface formed by the spiral nozzle 8 completely covers the tangent point of the tobacco leaf throwing surface in the roller. The weight of the lower tobacco in unit area is lightest, the weight of the upper tobacco in unit area is heaviest, the weight of the middle tobacco in unit area is centered, the height of scattering materials is 11 o' clock in the tobacco moistening roller 2, the lower tobacco is highest, and the upper tobacco is lowest. The height of the middle smoke as the coordinate origin of the nozzle frame 4 is used as a reference point, and the upper smoke and the lower smoke are accurately adjusted on the basis of the reference point in the production process.
The embodiment selects the spiral solid cone nozzle, the spiral solid cone nozzle is adopted to generate water vapor fog through water vapor flow cutting, and the water vapor fog generates transverse jet force while cutting, so that the diameter of the water vapor fog sprayed by the spiral solid cone nozzle is obviously larger than that of a standard solid cone nozzle, and the flow of a single nozzle is obviously increased. Because the mechanism that the solid toper nozzle of spiral produces vapor fog is spiral cutting, spiral nozzle 8 has good atomizing performance, the regional scope of atomizing is big, the dispersity index of spiral nozzle 8 presents the trend of increase along with the increase of pressure on the whole, it is more stable when steam pressure 0.2-0.5 Mpa, can provide stable, fine vapor fog during normal work, if meet the tobacco leaf raw materials of processing special demand, also can be in the cylinder exit, according to the principle of spiral nozzle 8 of entry end additional installation, spiral nozzle 8 is installed additional at the exit end, the moist leaf demand of all redried tobacco leaves can be satisfied in the double spray nozzle mode. The conventional 120-degree spiral nozzle 8 has 3 to 4 spraying layered interfaces, and even has a plurality of layered interfaces at other angles. The spraying effect is as follows: each interface forms a conical spray surface, and a spiral nozzle 8 has 3-4 conical spray surfaces as few as 3, and 6-7 spray surfaces as many as 6, so that the ideal choice for fine spraying is realized. According to the invention, a 120-degree spiral solid cone nozzle is adopted, fan-shaped multi-layer spraying is carried out by the nozzle just above the 11 o 'clock throwing surface of the leaf moistening roller 2, the 11 o' clock tobacco leaf throwing surface of the leaf moistening roller 2 is uniformly covered by the water-steam mixed fog surface under the pushing assistance of inlet hot air, and the water-steam fog layer is uniformly contacted with the material throwing layer in the roller in the largest area, so that the leaf moistening effect is enhanced to the maximum extent.
The nozzle rack 4 comprises at least two transverse rods and a longitudinal rod, the transverse rods are horizontally arranged along the horizontal direction, the two transverse rods are parallel to each other and are connected through a main rod, a sliding sleeve 5 is connected onto any transverse rod in a sliding mode, a water outlet pipe 7 is fixed on the front side of the sliding sleeve 5, and a locking bolt 6 used for positioning is installed on the rear side of the sliding sleeve 5. In this embodiment, the nozzle frame 4 is installed on the outer wall of the drum, and is made of a stainless steel material with scales connected in a longitudinal and transverse mode, and the nozzle frame has 5 transverse edges and one longitudinal edge, the length of the reference strip is 350mm, and the other upper transverse edge and the other lower transverse edge are 320mm and 290mm respectively. For noise reduction and elimination vibration, install horizontal pole and vertical pole rear side additional and all install the sealing strip.
Be provided with the scale on the horizontal pole, through setting up the scale, can carry out the accurate adjustment to the position of sliding sleeve 5 to make spiral nozzle 8 correspond moist leaf cylinder 2 all the time and throw the face.
