Description

Mobile tobacco electrostatic impurity removal device

Technical Field

The invention relates to an electrostatic impurity removal device, in particular to a mobile tobacco electrostatic impurity removal device.

Background technique

In the production process of the tobacco industry, it is inevitable that there will be impurities in tobacco or tobacco leaves caused by various factors such as manufacturing raw materials, production process, equipment shedding, and human errors. Common tobacco impurities include chicken feathers, plastics, metal impurities, etc. Metal impurities can be removed using metal detectors, and the removal rate is relatively high. As for non-metallic impurities such as chicken feathers and plastics, the current industry commonly uses visual recognition, wind selection and light and heavy screening to remove impurities. Visual recognition is to use a visual camera to take high-speed all-round photos, and then automatically identify the impurities through PLC, and then accurately identify and remove them, with a high removal rate. This principle method also has autonomous learning, but in the case of equipment wear, camera light source loss, camera wear, etc., the rejection rate is greatly affected, and when a camera is worn, it is difficult to determine the cause of the fault; wind selection light and heavy separation is to throw the tobacco into the air and absorb it, and large-mass impurities will fall, but it is ineffective for lightweight impurities such as plastics.

If non-metallic debris is mixed in the tobacco, there is a possibility that the cigarette making machine and packaging machine will be jammed during the cigarette rolling process, seriously affecting production efficiency. At the same time, if the tobacco industry's finished cigarettes contain debris such as plastic and chicken feathers, the cigarettes will directly affect the smoking experience when they are burned. When non-metallic debris is found in the silk-making process, due to the high degree of mixing of the tobacco, in order to ensure the purity of the product, the whole batch of tobacco is generally sorted manually, and the product will be further broken during the manual sorting process. At the same time, the sorting will cause the smell of tobacco sugar materials to be emitted, affecting the taste of the finished product. While increasing labor costs, it is impossible to ensure the purity of manual sorting. Therefore, in the tobacco industry, the removal of non-metallic debris has always been a difficulty and pain point in the industry, and it is also an inevitable demand for the industry to manufacture homogeneous and high-quality products.

The tobacco industry currently uses visual recognition and infrared emission impurity removal machines, which are greatly affected by the automatic recognition of cameras and systems. At the same time, different brands of tobacco have different raw material varieties, which results in different raw material qualities, which has a great impact on camera recognition and PLC autonomous learning. In actual use, the rejection rate (single-machine test experiment) generally reaches 60%, and the actual production is slightly lower than this value. The ability to remove light non-metallic debris is also limited.

Another method of impurity removal in the tobacco industry is light and heavy impurity removal. The principle is to air-dry the tobacco and suck it into the downstream process section under negative pressure, while large-mass impurities fall directly. This method is also not effective in removing light non-metallic impurities.

The existing tea industry generally uses the principle of electrostatic impurity removal. Fixed impurity removal devices are designed based on this principle, which means that the impurity removal devices can only be used in fixed process positions in production lines. Due to refined processing, the tea processing flow rate is relatively small, generally 100kg/h, which is far less than the production flow rate of 5000-9000kg/h in the tobacco industry. Therefore, the use of various types of tea electrostatic impurity removers cannot meet existing requirements. There are many electrostatic impurity removal devices in the tea industry, but they can all be adapted to small flow rates and are all fixed electrostatic impurity removal. They are not applicable to the tobacco industry where there are large flow rates and non-metallic debris hazards in each process segment.

In the tea processing industry, electrostatic impurity removal is a common impurity removal method. Because tea and tobacco have similar physical properties, and there are also non-metallic impurities in the tea, the tea industry generally adds a small flow of tea into the electrostatic impurity removal equipment. Without causing crushing, the electrostatic roller is used to adsorb the non-metallic impurities in the tea. This is a relatively mature impurity removal method.
