Urea-formaldehyde resin foaming and mixing device

Abstract

The invention relates to a urea-formaldehyde resin foaming and mixing device. The device comprises a foaming tank and a urea-formaldehyde resin tank which are communicated with a mixing device, wherein the mixing device comprises a foam inlet barrel, a feeding barrel, a mixing barrel and a discharging barrel which are connected in series in turn; the foam inlet barrel is connected with a foam outlet on the foaming tank; a plurality of feeding nozzles are circumferentially formed on the feeding barrel at intervals, and are connected with a glue outlet on the urea-formaldehyde resin tank; an impeller is axially arranged in the mixing barrel; the discharging barrel is provided with a discharging hole; both the foaming tank and the urea-formaldehyde resin tank are provided with an air pressure meter, an air inlet, a feeding inlet and a drain outlet; the two air inlets are connected with an air pump simultaneously; the air inlet on the foaming tank is connected with a vortex aeration pipe;the aeration pipe is attached at the bottom of the foaming tank, and a plurality of micron-sized small holes are uniformly distributed on the pipe wall of the aeration pipe; and the air inlet on the urea-formaldehyde resin tank is connected with an air pipe positioned above urea-formaldehyde resin. The device has high production efficiency and is convenient to operate; and the produced urea-formaldehyde resin foam has stable agronomic characters and is suitable for the fields of slope greening, wall greening and the like.

Description

technical field [0001] The invention relates to a mixing device, in particular to a urea-formaldehyde resin foaming and mixing device. Background technique [0002] Domestic existing foaming equipment used to produce urea-formaldehyde resin foam plant cultivation substrates is generally general-purpose equipment in other industries or non-pressure urea-formaldehyde resin foaming machines (for example: patent application number: 200810114285.6), and there is no special pressure-type injection at present. Type urea-formaldehyde resin foaming equipment. Since the original design intention of foaming equipment in other industries is not dedicated to the foaming of urea-formaldehyde resin, there are low production efficiency, inconvenient operation, and unstable agronomic properties of the produced urea-formaldehyde resin foam, which cannot effectively solve the problem of spraying urea-formaldehyde resin foam to a certain The problem of distance. Aiming at these production pro...
