Detailed Description
The technical solution provided by the present invention is explained in more detail below with reference to fig. 1.
Referring to fig. 1, the invention provides a tobacco shred winnowing system, which comprises a feeding vibration groove 1, a winnowing box 2, a first feeding device 3, an air outlet device 4 and a second feeding device 5. The winnowing box 2 is arranged at the lower part of the feeding vibration groove 1 and is communicated with the feeding vibration groove 1. The first feeding device 3 is arranged inside the winnowing box 2, and the first feeding device 3 is constructed to be telescopic; the first feeding device 3 is used for receiving the materials conveyed by the feeding vibration groove 1. The air outlet device 4 is communicated with the winnowing box 2, and the opening 41 of the air outlet device 4 is configured to be capable of air outlet or closing. The second feeding device 5 is positioned inside the winnowing box 2. When the first feeding device 3 is in an extending state, the materials conveyed by the first feeding device 3 are directly conveyed to the second feeding device 5; when the first feeding device 3 is in a retraction state, the first feeding device 3 and the second feeding device 5 are separated.
When air separation is not needed, the first feeding device 3 is in an extending state, and materials conveyed by the first feeding device 3 directly fall to the second feeding device 5. The air outlet device 4 is in a closed state, and the air outlet device 4 does not output air.
When needing the selection by winnowing, first material feeding unit 3 is in the withdrawal state, and opening 41 of air-out device 4 is opened, and air-out device 4 is in the air-out state, and air-out device 4 is used for the wind of selection by winnowing pipe tobacco to the inside transport of selection by winnowing box 2. The first feeding device 3 and the second feeding device 5 are spaced at a certain distance, and the material conveyed by the first feeding device 3 falls into the space and falls to the second feeding device 5 under the action of self weight after being winnowed by the wind output by the wind outlet device 4, and then is output by the second feeding device 5. Summarizing the air separation process, the opening 41 of the air outlet device 4 is simultaneously used as a blanking port for impurities, and heavier impurities fall into the air outlet device 4 through the opening 41 to realize the impurity removal of tobacco shreds.
In order to separate impurities in the cut tobacco, in some embodiments, the air outlet device 4 is positioned lower than the first feeding device 3.
Optionally, the position of the air outlet device 4 is lower than that of the second feeding device 5, so as to facilitate separation of impurities.
The position of the opening 41 of the air outlet device 4 is located between the first feeding device 3 and the second feeding device 5 in the retraction state, and the opening 41 is used as an impurity blanking port and an air separation air outlet at the same time, so that impurity removal can be realized just in line with the conveying direction of the materials.
In some embodiments, the first feeding device 3 comprises a telescopic belt conveyor. The telescopic belt conveyor is convenient to control and install.
In some embodiments, a telescopic belt conveyor comprises a support device and a belt. The belt is arranged on the supporting device, one end of the belt is provided with an adjusting roller 31, and the other end of the belt is used as an extending end.
In some embodiments, the second feeding device 5 also employs a belt conveyor. The belt feeder is used with flexible belt feeder cooperation, realizes whether the pipe tobacco passes through the selection by winnowing.
In some embodiments, an airlock 6 is provided downstream of the second feed device 5 to control the flow direction of the fluid.
Referring to fig. 1, in some embodiments, the tobacco shred winnowing system further comprises a return air duct 7, and the return air duct 7 is communicated with the winnowing box 2. The return air pipe 7 is communicated with the top of the winnowing box 2. The return air pipe 7, the air outlet device 4 and the winnowing box 2 form an air circulation loop, and air output from the air outlet device 4 enters the winnowing box 2 and then enters the return air pipe 7 to realize a flow path of the air. Further, the return air passing through the return air duct 7 can be reintroduced into the air outlet device 4 to form a circulation air path.
Further, a filtering device is provided downstream of the outlet of the return air duct 7 to remove impurities in the return air.
Some specific embodiments are described below.
Referring to fig. 1, the cut tobacco is fed into a first feeding device 3 of an air separation box 2 through a feeding vibration groove 1, and the first feeding device 3 is specifically a high-speed belt conveyor. The first feeding device 3 increases the speed of the cut tobacco from 0.8 m/s to about 3 m/s, so that the cut tobacco is spread and enters an air separation feeding port to be beneficial to air separation of the cut tobacco.
The finished cut tobacco is lighter in weight, is lifted by wind and finally falls into a second feeding device 5 in the winnowing box 2, and is sent into a discharging belt conveyor 8 after passing through an air material lock 6, so that winnowing is completed. The sundries such as the stems, the caked tobacco shreds and the like fall into the sundries blanking port (namely the opening 41 of the air outlet device 4) due to the heavier mass. In order to ensure that the cut tobacco does not lose water in the winnowing process, the air needs to be recycled, so that the process air is guided into the sundries blanking port through the internal circulation fan, and the internal recycling of the air is realized.
Referring to fig. 1, the first feeding device 3 adopts a telescopic belt, i.e. a regulating roller is added below the belt conveyor, and the extending end of the belt conveyor extends to the upper part of the second feeding device 5 in the winnowing box 2. When the cut tobacco winnowing machine is in a winnowing state, the first feeding device 3 is adjusted to the leftmost end shown in fig. 1, so that the adjusting roller 31 falls to the lowest point, a winnowing feeding opening (namely the opening 41) is opened, and all related components are started to realize the function of winnowing and screening the cut tobacco. When the cut tobacco winnowing machine is in a non-winnowing state, the first feeding device 3 is adjusted to the rightmost end, so that the adjusting roller 31 is lifted to the highest point, and the winnowing feeding opening (namely the opening 41) is closed. In the production process, the fan of the air outlet device 4 is closed, and only other internal components are started, so that the air separation system has the function of serving as a channel.
Above-mentioned technical scheme through increasing the dancer rools of belt feeder below and stretching out the end mechanism, has realized that the difference of high-speed belt feeder stretches out the volume and adjusts the function whether selection by winnowing, simple structure, convenient operation has realized the function whether selection by winnowing of pipe tobacco with minimum transformation volume, has practiced thrift the equipment investment. Meanwhile, the structure is arranged in the winnowing box 2, the structure of the winnowing box 2 is basically not changed, the flow field distribution in the winnowing box 2 is not influenced, and obvious economic benefit is obtained.
The cut tobacco winnowing system can be used for a cut tobacco production line, has a good screening effect on rejected stem sticks and agglomerated cut tobacco mixed in finished cut tobacco, effectively improves the quality of the finished cut tobacco, is simple and convenient to operate, shortens debugging time for trial production switching of products, reduces transformation cost, and obtains good economic benefits.
