Further, a pressure control valve is arranged on the air distributing cylinder.
Further, a pressure gauge is arranged on the branch cylinder.
And furthermore, the device comprises four nozzles, each nozzle is communicated with the gas distribution cylinder through a gas outlet pipe, and a gas outlet valve is arranged on each gas outlet pipe.
Further, the air outlet valve and the pressure control valve are both electromagnetic valves, and the photoelectric detection switch, the air outlet valve, the pressure control valve and the air source are respectively and electrically connected with the controller.
Further, the blowing angle of the nozzle is 40-50 degrees.
Further, the blowing angle of the nozzle is 45 °.
The utility model has the advantages that: the utility model discloses an automatic jetting device of tobacco stem drying machine, including photoelectric detection switch, jetting unit and controller, the jetting unit includes air supply, gas distribution cylinder and nozzle, the air supply passes through the intake pipe and communicates with the gas distribution cylinder, the gas distribution cylinder passes through the outlet duct and communicates with the nozzle, be provided with the air outlet valve on the outlet duct; the controller is respectively and electrically connected with the photoelectric detection switch and the blowing unit. Adopt the automatic jetting device of tobacco cut tobacco stem drying machine of this application, can avoid the stalk piece to arrange material pipe department jamming, make the stalk piece can in time discharge and avoid forming carbonization stalk, production mars, and then avoided causing the loss of stalk silk.
Drawings
The invention is further described with reference to the following figures and examples.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a schematic application diagram of an embodiment of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, as shown in fig. 1-2: the embodiment provides an automatic blowing device of a tobacco cut stem drying machine, which comprises a photoelectric detection switch 5, a blowing unit and a controller 4. The photoelectric detection switch 5 may be disposed inside the discharge pipe 2 connected to the discharge port 102 of the drying tower 1, or disposed at the discharge port of the discharging device 6, in this embodiment, the photoelectric detection switch 5 is disposed at the discharge port of the discharging device 6, and whether the discharge pipe is stuck or blocked is determined by detecting whether discharging is performed, and if discharging is not performed, it is determined that the discharge pipe is stuck. The photoelectric detection switch comprises a light emitting end and a light receiving end, when the material is unloaded, light is blocked by the material, the light receiving end cannot receive feedback, and when no material is unloaded
When the discharging pipe is blocked by the stem blocks, the light is not blocked, and the light receiving end receives feedback. It is necessary to note that the photodetection switch is a prior art, and further supplementary description is not provided here. The blowing unit comprises an air source 302, a gas distribution cylinder 301 and four nozzles 308, wherein the air source 302 is communicated with the gas distribution cylinder 301 through an air inlet pipe 303, the gas distribution cylinder 301 is respectively communicated with the nozzles 308 through air outlet pipes 304, each air outlet pipe 304 is provided with an air outlet valve 305, and the blowing angle of the nozzles 308 is 40-50 degrees, preferably 45 degrees. When the nozzles 308 are specifically installed, the four nozzles 308 are distributed on two sides of the discharge pipe 2, two of the nozzles 308 are positioned at the upper end and the lower end of one side of the discharge pipe, the other two nozzles 308 are positioned in the middle of the other side of the discharge pipe, and the nozzles 308 on the two sides face each other to inject air into the discharge pipe 2, so that the coverage of air blowing can be improved. The air distributing cylinder 301 is provided with a pressure control valve 306 and a pressure gauge 307. The gas outlet valve 305 and the pressure control valve 306 are both electromagnetic valves, and the photoelectric detection switch 5, the gas outlet valve 305, the pressure control valve 306 and the gas source 302 are respectively electrically connected with the controller 4.
The working principle is as follows:
when the photoelectric detection switch detects that the discharge pipe is clamped and lagged, a signal is fed back to the controller, the controller controls the air source to be started, the air outlet valve to be opened, air is blown into the discharge pipe through the nozzle, the stem blocks at the lower part in the discharge pipe are loosened and fall, the stem blocks at the upper part float upwards and are removed by winnowing along with the stem shreds to the next process, long-time clamping stagnation in the discharge pipe is prevented, and accidents and stem shred loss caused by the fact that carbonized stems are formed due to the fact that the stem blocks cannot be timely discharged are avoided. When the pressure sensed by the pressure control valve reaches a set value (usually 8MPa), a signal is fed back to the controller, the controller controls the air outlet valve to be closed, and air supply in the line discharge pipe is stopped.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
