Description

Compound cylinder oven dry dressing machine

Technical field: the utility model relates to a kind of compound cylinder oven dry dressing machine equipment, be to belong to the special equipment of producing composite microbiological fertilizer, biological organic fertilizer, it provides fertilizer for production pollution-free food, pollution-free food, has promoted the development of ecological agriculture sustainable agriculture.

Background technology: at present, the microbial manure that China produces can be divided into the three major types type---microbial inoculant, composite microbiological fertilizer and biological organic fertilizer.And composite microbiological fertilizer is commonly called as three-in-one microbial manure, and the synergy of long-acting and bio-fertilizer that it has quick-acting, the fertilizer of collection inorganic fertilizer is the advantage of one.But composite microbiological fertilizer has two problems to resolve in manufacturing process: easily produce the rear phenomena of mortality of being heated when first microorganism is dried in granulation process, second microorganism is with after the N,P,K fertilizers of high-load mixes mutually, in the hyperosmosis situation, microorganism easily loses activity.This is two good problems anxious to be resolved in the present microbial manure composting process.Through the retrieval of patent documentation and related data, do not find close technical scheme.

Summary of the invention: the purpose of this utility model is for addressing the above problem weak point, propose a kind of technical scheme of Combined drum drying coaters, granular fertilizer can be solved the oven dry problem in Drying, can finishing again the equipment that dressing is purpose simultaneously.It is length lengthening with the former oven dry tube of prior art; Near hot-blast stove hot gas mouth is promptly dried the right-hand member of tube, establish a heat conduction airduct again, directly insert the interior left half part of oven dry tube, hot blast can be directed at its left side; Establish an automatic closed microbial inoculum charging aperture at oven dry tube middle part; Near the left end of oven dry tube, add a FE Glue Gun conduit, directly be inserted into the microbial inoculum charging aperture place in the oven dry tube, can eject adhesive, and mix with microbial inoculum; After particle fertilizer enters the oven dry tube by particle fertilizer charging aperture, meet thermal current earlier, smash at screw-pushing type under the promotion of flitch, carry out the adverse current oven dry earlier, when material enters the middle part of oven dry tube, smash at the curve screw-pushing type under the promotion of flitch, carry out coating with adhesive, microbial inoculum mixture, the heat that utilizes the heat conduction airduct to distribute again, coated granules fertilizer is dried, enter the double-deck screen cloth that divides at last, obtain the different coated granule fertilizer of diameter respectively, in first number or second number qualified fertilizer discharging opening place pack packing.This Combined drum drying coaters is characterised in that: it is to be formed a whole by Drying, Drying supporting seat, blast cap, elevator, double-deck screen cloth and hot-blast stove 6 parts of dividing; Blast cap is the left end that is enclosed within Drying, establishes a granular fertilizer charging aperture in the upper part of blast cap, and a FE Glue Gun conduit is established in its side, directly inserts the middle part in the Drying; Establish an automatic closing type microbial inoculum charging aperture at the middle part of Drying, and corresponding with the microbial inoculum funnel on elevator top; Around Drying, establish interlayer insulating layer; The mounting inclination angle degree is smash flitch less than 90 ° of screw-pushing types in the same way on the inwall of Drying left half part, it is with the helical orbit layout, on the inwall of Drying right-hand part position, installed with Drying curve screw-pushing type in the same way and smash flitch, be rectangular curve shape, it is with gap, banded helical orbit layout; Right-hand member at Drying is connected to form one with the double-deck screen cloth that divides, and bilayer divides the following position of screen cloth, is respectively equipped with the sequence of dust discharging opening, first number qualified fertilizer discharging opening, second number qualified fertilizer discharging opening and waste material discharging opening; At hot-blast stove hot gas mouth place, to establish a heat conduction airduct, and be enclosed within on the hot-air mouth, this heat conduction airduct is connected and fixed with the double-deck screen cloth that divides, and directly is inserted on the left half part in the Drying; Two Drying supporting seats are arranged below the Drying, its left end slightly high, right-hand member slightly low makes the Drying of integral body be in heeling condition.

Advantage of the present utility model is as follows:

(1) in Drying, finishes oven dry and the dressing of fertilizer, enlarged the purposes of Drying, reduced coating device, saving fund and the energy.(2) Drying liner heat conduction airduct and Drying synchronous rotary are delivered to the first half of Drying with the hot blast that produces in the hot-blast stove, finish the oven dry to fertilizer.(3) because hot blast concentrates on the left side of Drying, improved the thermal efficiency.At the right-hand part of oven dry tube, the heat that utilizes heat conduction airduct tube wall to distribute is finished the oven dry to the coated fertilizer particle, makes it reduce moisture.(4) owing to have the heat conduction airduct to be separated by between hot blast and the fertiliser granulates, avoid hot blast directly to contact with fertiliser granulates, as long as control temperature well, just can reduce the death rate of bacterium.(5) the microbial inoculum dressing has reduced microbial inoculum and has directly contacted with npk fertilizer in the fertiliser granulates outside, has improved the survival rate of effective bacterium, has guaranteed the quality of composite microbiological fertilizer.
