In order to solve the problems that in the prior art, a foaming device is low in foaming efficiency and high in energy consumption, according to the technical scheme, the foaming device achieving porous air intake and exhaust comprises a foaming barrel, an air intake mechanism, an exhaust mechanism, a material door cylinder and a stirring mechanism; a feeding opening is formed in the foaming barrel; the air intake mechanism is mounted at the bottom of the foaming barrel; the exhaust mechanism is mounted at the top of the foaming barrel; the material door cylinder is mounted at a material door of the foaming barrel; the air intake mechanism comprises a main air intake pipe, a first filter, a second filter, a first steam pocket, a second steam pocket, a third steam pocket, a pressure reducing valve, a steam proportional valve, an air proportional valve and a porous air intake pipeline; the main air intake pipe is connected with the first filter; the first filter is connected with the first steam pocket and the second steam pocket; the first steam pocket and the second steam pocket are connected in parallel; and the second filter is connected with the first steam pocket and the second steam pocket. The foaming device is high in foaming efficiency and achieves energy saving and environment protection.

Description

technical field [0001] The invention relates to a foaming device and a foaming method thereof, in particular to a foaming device for porous air intake and exhaust and a foaming method thereof. Background technique [0002] At present, when the foaming device on the market is working, steam with a certain temperature is generally introduced into the foaming tank. After a certain period of time, the EPS hard particles will expand into light foam particles; when the foam particles reach the specified After the density is reached, open the discharge port of the foaming tank to discharge the material. However, the existing foaming device still has the problems of low foaming efficiency, uneven heating of raw materials and high energy consumption. [0003] The Chinese patent with the publication number CN201042837 discloses an EPS foaming machine, which includes a feeding mechanism, a foaming tank, a drying bed, connecting pipelines between various components and a control system...

Problems solved by technology

However, the existing foaming devices still have the problems of low foaming efficiency, uneven heating of raw materials and high energy consumption.

[0003] The Chinese patent with the publication number CN201042837 discloses an EPS foaming machine, which includes a feeding mechanism, a foaming tank, a drying bed, connecting pipelines between various components and a control system, and the steam on the foaming tank There are few inlets and steam outlets, low foaming efficiency, and uneven heating of foam particles; the Chinese patent with the publication number CN207140200U discloses a high-efficiency steam pre-foaming machine, which is set by a spiral stirring belt and a mixing barrel, When the device is pre-foaming the material, the material in the mixing tank can be heated evenly, so as to ensure the foaming quality of the material. The steam inlet and steam outlet on the mixing tank of the invention are less, and the foaming efficiency is low.
