Description
Technical Field
The utility model relates to a cleaning device for an impact water bath type hot air circulation system, and belongs to the technical field of tools.
Background
The tobacco moistening machine is key equipment of a pretreatment section of a threshing and redrying processing production line, and mainly has the effects of loosening and conditioning tobacco leaves by adopting hot and humid air, and simultaneously controlling the temperature and the water content of the tobacco leaves, so that good conditions are provided for subsequent leaf and stem separation processing.
The leaf wetting machine mainly comprises a leaf wetting cylinder, a hot air circulation system and other systems, wherein the hot air circulation system is provided with a forward flow type hot air circulation system and a reverse flow type hot air circulation system (the forward flow type hot air circulation system is used for illustration), the hot air circulation system mainly comprises a hot air suction inlet, a hot air cleaning device, a circulating fan, a steam radiator, a hot air outlet and related air pipes, and the hot air suction inlet and the hot air outlet are respectively connected with a discharge end and a feed end of the leaf wetting cylinder. The hot air circulation process is as follows: the method comprises the steps of a leaf wetting cylinder discharging end, a hot air cleaning device, a circulating fan, a steam radiator, a leaf wetting cylinder feeding end, a leaf wetting cylinder inner part and a leaf wetting cylinder discharging end. The steam radiator is the most important component.
The main functions of the hot air circulation system are that the waste heat (the damp and hot air which is not completely absorbed by tobacco leaves) is recycled, the temperature of circulated air is increased through a steam heat exchanger, and the temperature and the water content of the tobacco leaves are accurately controlled. The working condition of the hot air circulation system directly influences the tobacco leaf moistening processing quality, and then influences the subsequent leaf and stem separation processing quality (leaf structural index).
Blockage of the hot air circulation system (particularly blockage of the steam radiator) is one of the most important reasons for affecting the normal operation of the leaf wetting machine. The blockage is caused mainly because the tobacco leaves contain scattered tobacco flakes, light sundries, dust and other floating matters, and the floating matters can be caused by entering a hot air circulation system along with air flow. Therefore, a hot air cleaning device is arranged at the front end of the air circulation system and is used for separating out floating matters in hot air and keeping the air flow smooth, so that the normal operation of the steam radiator and the normal operation of the leaf wetting machine are ensured.
The hot air cleaning device commonly used for the leaf wetting machine of the threshing and redrying production line at present comprises a net drum type cleaning device and a cyclone centrifugal cleaning device, and the two modes are not good in practical operation, and the reason is that the characteristics and the working conditions of circulating hot air are not known. Both cleaning modes are analyzed as follows.
The net drum type cleaning device works by forming a plurality of small holes (usually 2-3 mm in diameter) on a rotating drum and filtering sundries in hot air by using the net holes. Because the humidity of the circulating hot air is very high, the circulating hot air contains sundries such as scattered blades, dust, hemp threads and the like, the viscosity of the circulating hot air mixed together is very high, the circulating hot air is easy to adhere to and block meshes, and even if a special cleaning mechanism is arranged, the circulating hot air is difficult to clean. And sundry dust with the size smaller than that of the mesh holes inevitably enters the subsequent steam radiator, so that the normal work of the steam radiator is affected.
The cyclone centrifugal cleaning device works in such a way that tobacco flakes and sundries with larger mass fall on the wall of a cylinder by utilizing the centrifugal force of hot air rotating in a cyclone cylinder and then are cleaned. Because the hot air contains sundries such as scattered blades, dust, hemp threads and the like, the viscosity of the mixture is very high, the mixture adheres to the cylinder wall, the formed concrete-like condensate is very difficult to clean, and the accumulated and formed thick layer causes the failure of the cyclone centrifugal cleaning device.
Therefore, both cleaning modes have great defects, so that the hot air circulation system cannot continuously work normally, and the two cleaning modes (devices) become main parts of blockage of the hot air circulation system.
The utility model aims at the defects of the cleaning mode (device) of the existing hot air circulation system, and the hot air circulation system of the leaf wetting machine can continuously and stably run to exert the normal functions of the hot air circulation system, so that the leaf wetting processing quality is improved.
