Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco processing equipment, and more specifically to a device for stabilizing the temperature and humidity of an air source of leaf shred air separation equipment. Background Art
[0002] Air separation equipment uses airflow to remove heavy impurities from tobacco products. With its simple principle, low investment, and high efficiency, it is widely used in cigarette manufacturing, for example, in the air separation of cut stems, air conveying of cut stems, air separation and impurity removal of tobacco leaves, air separation of cut tobacco leaves, and air conveying of cut tobacco. The air separation process removes major impurities such as stem sticks, stem particles, burnt flakes, particles, and wet clumps from the dried tobacco leaves, while also improving the structural uniformity of the tobacco leaves to meet the requirements of subsequent processing steps.
[0003] During the leaf silk air separation process, leaf silk air separation equipment is used. In order to reduce the dust concentration of the circulating air, the maximum circulating air ratio is generally controlled at ≤85%. During the air separation process, it is still necessary to add about 8000m3 of dust from the silk workshop environment. 3 / h of fresh air volume. Existing leaf shred air separation equipment has an air supply port that is open to the outside environment. The air supply port draws ambient air from the tobacco-making workshop through the negative pressure inside the equipment to replenish the equipment with fresh air. However, the temperature and humidity of the ambient air on site vary with the season and weather, and the quality of the fresh air supplied during the air separation process is uncontrollable. This results in high uncertainty in the moisture and temperature loss of the leaf shreds under different weather conditions. The uniformity and stability of the temperature and humidity loss of the leaf shreds significantly affect the moisture balance, structure, filling value of the tobacco shreds after drying, and even the rolling quality and consumption. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a device for stabilizing the temperature and humidity of the air source of the leaf silk air separation equipment to ensure that the temperature and humidity of the fresh air supplied from the air supply port of the leaf silk air separation equipment are constant, thereby solving the problem of product quality fluctuations caused by fluctuations in the temperature and humidity of the supply air.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A device for stabilizing the temperature and humidity of the air source of a leaf shred air sorting device, wherein the air supply port of the leaf shred air sorting device is connected to an external air supply pipe, the outlet end of the air supply pipe is connected to the air supply port of the leaf shred air sorting device, the inlet end of the air supply pipe extends to a constant temperature and humidity area and is connected to the air outlet of a fan, the fan is placed inside the constant temperature and humidity area, and an anemometer and an air damper are provided on the air supply pipe.
[0007] As a preferred embodiment of the above device, the constant temperature and humidity area is a mixing room, the fan is installed in the mixing room, and the air supply pipe passes through the insulation board on the top of the mixing room and is connected to the air outlet of the fan.
[0008] Compared with the existing technology, the beneficial effects of this utility model are embodied in:
[0009] The utility model provides a device for stabilizing the temperature and humidity of the air source of a leaf silk air sorting equipment. The device draws constant temperature and humidity air from the mixing room through a fan and transports it to the air supply port of the leaf silk air sorting equipment, which serves as the air source for the fresh air of the leaf silk air sorting equipment. By stabilizing the temperature and humidity of the air supply source of the leaf silk air sorting equipment, the fluctuation of the leaf silk quality caused by the change of the on-site air temperature and humidity is avoided, and the uniformity and stability of the temperature and humidity loss of the leaf silk are ensured. In addition, the device utilizes the stable air in the mixing room nearby, and there is no need to set up a constant temperature and humidity air source separately, thus saving costs.
