Description

TECHNICAL FIELD

[0001] The present application relates to the field of cyclone separation components, in particular to a hot melt adhesive cyclone separation component. BACKGROUND

[0002] Hot melt adhesive is a kind of adhesive glue, which is mainly used for bonding objects to form a whole. In the production process of hot melt adhesive, a cyclone separation component is often used to treat the waste gas generated in the production process. The cyclone separator is a device used for separation of gas-solid or liquid-solid system. Its working principle is to make solid particles or liquid droplets with large inertia centrifugal force separate by rotating motion caused by tangential introduction of gas flow. The main features of the cyclone separator are simple structure, large operation flexibility, high efficiency, convenient management and maintenance, low price, and it is used to capture dust with a diameter of 5-10 μm or more, and is widely used in pharmaceutical industry, especially suitable for coarse dust particles and high dust concentration, under high temperature and high pressure conditions. It is also often used as an internal separation device of a fluidized bed reactor or as a pre-separator. It is a widely used separation device in industry.

[0003] Patent No. CN211635853U discloses a cyclone separation component, which comprises a fixed component and a filtering mechanism. The upper and lower ends of the fixed component are respectively provided with the filtering mechanism. If the cyclone separator is a middle-end air inlet, the upper and lower fixed ears are inserted into the corresponding insertion grooves of the cyclone separator, and the filtering mechanism is installed on the upper and lower fixed plates respectively. The gas entering the filtering mechanism is filtered through the upper and lower fixed plates. If the cyclone separator is an upper-end or lower-end air inlet, the filtering mechanism on the upper or lower fixed plate is disassembled, the upper and lower fixed plates are combined, and the combined upper and lower fixed ears are inserted into the corresponding position in the cyclone separator by using the fixing bolt to lock. This effectively improves the installation compatibility of the filtering component and reduces the assembly cost.
