Problems solved by technology

However, the main problems and disadvantages of the traditional vibrating sieve process are as follows: (1) The mesh of the vibrating sieve is easily blocked, resulting in unstable quality of long stems. 2) Long-stem products have high waste content, which affects the quality of long-stem products; (3) The long-stem products produced are not easy to cool, and the temperature of bagging (box) is usually above 55°C, which often causes condensation and mildew in the bag (box) , Carbonization loss problem, and it is difficult to solve; (4) The open structure of the vibrating screen leads to a large amount of dust in the production site, high dust concentration, and clean production is not easy; (5) The equipment used for screening The quantity is large, there is not only the problem of high mechanical vibration and noise of the crank mechanism of the vibrating screen equipment, but also the large number of moving parts such as shrapnel, crank mechanism, bearings, etc., resulting in high equipment failure rate and high equipment maintenance costs; there are also problems The energy consumption of screening equipment is as high as 20kw or more, which is at a relatively high level
[0004] There used to be a problem that the sieve hole of the needle vibrating sieve was easy to be blocked, and the research and practice of the mechanical device for automatic cleaning of the sieve had been carried out, or the cleaning and dredging of the sieve hole of the sieve, and the increase in the long-stem rate had achieved certain results. Some disadvantages of its own, such as: high dust concentration in the open type, high failure rate of moving parts such as crank shrapnel, high energy consumption of equipment, large vibration and noise, and other problems have not been solved so far. As for how to recycle the entrained in the stem The problem of improving the production rate of fragmented smoke has no time to take into account and cannot be taken care of. Therefore, the old vibration screening process is far from the management requirements of modern enterprises, and has become one of the main focuses of leaf threshing and redrying enterprises.

Embodiment

[0054] 1. The five-sided sieve 1.2 is used as the core technical equipment for the screening of re-cured tobacco stems, and the corresponding auxiliary equipment bag filter equipment 1.2-1.6 ( figure 2 , Figure 6 , Figure 7 ), which constitutes the re-cured tobacco stem screening function module 1, which can realize the technological function of screening the re-cured tobacco stems into four kinds of materials including fine short stems, short stems, long stems and stalks;

[0055] 2. With the quantitative bagging scale as the main equipment, it is equipped with corresponding auxiliary conveying equipment ( figure 2 ), which constitutes the stalk product bag packaging module 2, to realize the process functions of carrying out quantitative bagging 2.2, 2.4 and 2.6 to the thin short stalks, short stalks and long stalks; The process function of bagging or basketting 2.7 at the head;

[0056] 3. The main equipment is roller table electronic scale, vibrating roller table, hy...

Abstract

The invention relates to a new technological method for screening redried tobacco stems, and the new technological method is used for a tobacco threshing and redrying production line in tobacco industry. The new technological method is based on a closed type five-face sieve rolling tobacco stem sorting machine technology, applies a modular integration method, defines important processing functions such as screening the redried tobacco stems, packaging stem products by using bags, packaging long stems by using cartons, carrying out online disfigurement on the stems and recycling tobacco fragments in the processing procedures of the redried tobacco stems as five functional modules, and organically integrates all the functional modules, thereby achieving the online processing technical aims such as screening the redried tobacco stems only by applying a five-face sieve machine, packaging the stem products by using the bags, packaging the long stems by using the cartons, carrying out online disfigurement on the waste tobacco stems in a centralized way and recycling tobacco fragments; therefore, the long stem rate quality index in the processing procedures of the redried tobacco stems is improved to the standard level of more than or equal to 85%, and is maintained to be stable, and the fragment yield of the recycled tobacco fragments is increased by about 0.25%, so that the economic benefit of an enterprise is improved; furthermore, the new technological method has better social benefit in the aspects of energy conservation, safety and environmental protection.

Description

Technical field: [0001] The invention relates to a new process method for screening redried tobacco stems used in the tobacco leaf threshing and redrying production line in the tobacco industry. Background technique: [0002] Tobacco stems are one of the indispensable and important raw materials for the cigarette industry. Threshing and redrying enterprises need to screen mixed tobacco stems of different lengths produced during the production process, in order to allow longer-sized tobacco stems to be stored for a long time without occurrence of Mildew and carbonization loss, the re-baking factory needs to re-baked the mixed tobacco stems of different lengths produced in the leaf-threshing process, and then used screening equipment to screen the different lengths of the re-baked tobacco stems. , short stalks, tobacco powder and stalks are sieved to separate them. Among them, the long stalks with a length of tobacco stalks (the industry standard in China, which is different i...
