Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] The present invention adopts air bubbles as carriers, mixes urea-formaldehyde resin and air bubbles uniformly, makes the colloidal urea-formaldehyde resin adhere to the surface of air bubbles and solidifies, so as to obtain better urea-formaldehyde resin foam products.

[0015] Such as figure 1 , figure 2 As shown, the present invention includes a closed foaming tank 1 and a closed urea-formaldehyde resin tank 2 , and both the foaming tank 1 and the urea-formaldehyde resin tank 2 communicate with a mixing device 3 . In the mixing device 3 , a foam inlet cylinder 31 , a feed cylinder 32 , a mixing cylinder 33 and a discharge cylinder 34 are sequentially connected in series, and the two cylinders are connected by threads, which is easy to dismantle and easy to clean. The foam inlet cylinder 31 is connected to the foam outlet 10 on the top of t...

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...
