Technical field：
The present invention relates to growing nursery and culture matrix production technical field, more particularly to a kind of urea formaldehyde resin foam particle matrix
Mobile factory.
Background technology：
Soilless culture (soiless culture) refers to that garden crop is cultivated without natural soil with matrix or only nursery
When matrix, nursery or cultivation matrix are respectively, the cultural method irrigated with nutrient solution after field planting can save soil
Ground, due to soilless culture can the good rhizospheric environment of artificial creation, effectively prevent soil even do disease and soil salt accumulation make
Into physiological barrier, the need for fully meeting crop to environmental conditions such as mineral nutrition, moisture, gases, the basic material of cultivation
Material again can recycle, therefore with water-saving, save fertilizer, saving of labor, high yield and high quality the features such as.
Urea formaldehyde resin foam has that quality is light, water absorbing and retaining properties are good, manufacture abundant raw material, cheap, process is simple etc.
Plurality of advantages, soilless culture substrate newer at present, instead of vermiculite and perlite, is covered thereon using urea formaldehyde resin foam plate
There is turf/stalk/mushroom bran to provide organic matter, humic acid and nutrition.This matrix is tabular to urea due to wherein lower floor
The comparatively high consumption of urea formaldehyde foam, aperture porosity is enriched, and macroporsity is not enough, therefore breathes not ideal enough to crop root, separately
It is outer to need to cover thicker turf/stalk/mushroom bran layer etc. on upper strata, and seedling is taken root on urea formaldehyde resin foam plate, it is impossible to
Secondary, three seedling separations are carried out, time main root and the destruction of main radicula system are serious during transplanting, and nutriment is not easily accessible to root, or moves
Absorption function is destroyed when planting seedling separation, and effect is not ideal enough.And the volume ratio of its raw material of urea formaldehyde resin foam and product is
1：Ton raw material of 20, i.e., one can be with 20 times of urea formaldehyde resin foams of volume of output, and because density is too small, this proposes difficulty to transport
Topic, even if it is also uneconomical to fill compartment.Other urea formaldehyde resin foam particle production equipment is more expensive, and each matrix factory is equipped with one
Not only financial burden was heavy but also can cause the idleness of equipment for set.
The content of the invention：
In consideration of it, being necessary to design a kind of economic, efficient urea formaldehyde resin foam particle matrix mobile factory.

Discharge end, reduces so that Lauxite gradually from hair-dryer side to the conduit discharge end of material-falling hopper side reaction container top height
The path of drift is consistent with the direction of conduit discharge end height reduction with the wind from after discharge end spilling for foam particle；Material-falling hopper discharges
Mouthful straight down and on conduit discharge end, material-falling hopper is used to scatter nutrition powder is dispersed；Receiving warehouse is located at
Material-falling hopper lower section；High-pressure pump is connected with reaction vessel, and high pressure valve is provided between high-pressure pump and reaction vessel；Reaction vessel
Inside it is provided with electric heater unit；Electric heater unit, hair-dryer, material-falling hopper, high-pressure pump are powered by external power supply.
Preferably, material-falling hopper is oscillatory type material-falling hopper.
Preferably, conduit is changeable type, and the bore of its discharge end is different.
Preferably, hair-dryer is blower fan.
Preferably, the direction of conduit discharge end height reduction be from direction from headstock to the tailstock.
Preferably, container side wall is provided with window, and top is provided with skylight；Container top is provided with air inlet at headstock
Mouthful, container afterbody is provided with exhaust outlet, so as to form inner air flowing, at the same by air inlet be located at top avoid it is near the ground
Dust cross and be entrained into inside.
Reasonably be arranged in container urea formaldehyde resin foam particle production equipment by the present invention, in that context it may be convenient to by the whole series
Equipment conveying reduces the equipment purchase burden of each matrix factory to different matrix factories, also achieves and " gives birth to nearby
Produce, use nearby ", reduce the problem of product storage transport；Turned waste into wealth using container, using its globality, closure
A whole set of urea formaldehyde resin foam particle production equipment easily can be easily placed in the place of needs, module metaplasia is realized
Produce, transport.
