Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0013] As shown in the figure: the double-cyclone powder recovery system in the embodiment is mainly composed of a primary cyclone separator 2, a secondary cyclone separator 3 and a recovery fan 4. The air inlet of the primary cyclone separator 2 is used to connect the spray The powder chamber 1 and the air outlet of the primary cyclone separator 2 are connected to the air inlet of the secondary cyclone separator 3 through the air pipe, and the air outlet of the secondary cyclone separator 3 is connected to the recovery fan 4 through the air pipe.

[0014] In this embodiment, the primary cyclone separator 2 is a cyclone separator suitable for recovering powder particles of 5 μm or more, and the secondary cyclone separator 3 is a cyclone separator suitable for recovering powder particles of 5 μm or less.

[0015] The working principle of the present invention is...

Abstract

The invention relates to a duplex-cyclone powder recovery system. The system is characterized by comprising a first stage cyclone separator, a second stage cyclone separator and a recycling fan, wherein an air inlet of the first stage cyclone separator is connected with a powder spray chamber, an air outlet of the first stage cyclone separator is connected with an air inlet of the second stage cyclone separator by an air pipe, and an air outlet of the second stage cyclone separator is connected with the recycling fan by another air pipe. The duplex-cyclone powder recovery system is simple in structure and reasonable in design, is thoroughly free of the problem of blockage, and enables the wind pressure and flow of the recycling fan to be balanced and constant.

Description

technical field [0001] The invention relates to powder coating recovery technology, in particular to a double-cyclone powder recovery system. Background technique [0002] In the powder coating process, the powder needs to be recovered in time. The current powder coating recycling technologies usually adopt the following types: (1) Single-stage filter element recovery; (2) Cyclone separator + filter element recovery; (3) Cyclone separator + filter element + sintered plate recovery. However, the above-mentioned several powder coating recovery technologies all have the problem of blockage of the recovery system, which will affect the wind pressure and flow rate of the recovery fan, and then affect the spraying quality of the product. In addition, in the powder spraying process, the powder is made of plastic particles with different particle sizes mixed in a certain proportion. The existing powder recycling technology is all recycled uniformly. After the recycled powder is mix...
