Abstract
The invention discloses a working method for a feed cooling device. The working method comprises the following working steps of (1) introducing cooling air into a headwind pipeline, and then, adding to-be-cooled feed into a feeding hole; (2) cooling the feed by enabling the feed to be in contact with the cooling air in a process of dropping from the upper part of a cooling tower body, and finally, dropping the feed to the bottom in the cooling tower body, and discharging the feed from a discharge hole; (3) when discharge amount needs to be reduced, increasing the opening degree of a regulating valve on a regulating pipeline to increase the amount of gas sprayed out by a gas spray nozzle, and increasing resistance force, at the discharge hole of the cooling tower body, of the sprayed-out gas, thereby reducing the discharge amount; and (4) when the discharge amount needs to be increased, reducing opening degree of the regulating valve on the regulating pipeline to reduce the amount of gas sprayed out by the gas spray nozzle, and reducing resistance force, at the discharge hole of the cooling tower body, of the sprayed-out gas, thereby increasing the discharge amount.
Description
Technical field
The present invention relates to and be a kind ofly exclusively used in the apparatus preparing animal feeding-stuff, be specifically related to a kind of method of work of feed cooling device.
Background technology
Feed, be the general name of the food of everyone domesticated animal, more narrowly general feeds mainly refers to the food of agricultural or animal husbandry domesticated animal.Feed comprises the feedstuff of soybean, dregs of beans, corn, fish meal, amino acid, more than ten kinds such as the assorted dregs of rice, additive, whey powder, grease, meat meal tankage, cereal, sugar grass.
Raw material pulverizing, batching, mixing, the steps such as cooling and finished product packing of granulating is generally included in the production process of feed, wherein granulation cooling step carries out usually in cooling tower utilizing adverse wind body, in the process of feed cooling, existing cooling tower utilizing adverse wind body is typically provided with and regulates the load of the structures such as valve to feed of discharging to regulate, but in adjustment structure place often buildup of feed such as valves, and above feed can continue to be bonded in, be unfavorable for very much cleaning, and easily result in blockage.
Summary of the invention
The object of the present invention is to provide a kind of method of work of feed cooling device, during by said method cooling feed, do not need the feed clearing up discharging regulating structure place, and not easily result in blockage.
For achieving the above object, base case of the present invention is as follows:
A method of work for feed cooling device, this cooling device comprises cooling column body and contrary wind pipeline, and described cooling column body top is provided with charging aperture and exhaust outlet, and cooling column body lower end is provided with discharging opening, and described contrary wind pipeline one end is communicated with cooling column body bottom; It is characterized in that, also be provided with and regulate pipeline and air nozzle, described cooling column body discharge outlet circumferentially has multiple described air nozzle, and the jet direction of each air nozzle is inclined upwardly, and each air nozzle all with adjustment pipeline communication, described adjustment pipeline is provided with control valve; Comprise following job step:
(1) first in contrary wind pipeline, pass into cooling air, then in charging aperture, add feed to be cooled;
(2) feed contacts cooled from the top of cooling column body toward the process fallen with cooling air, finally falls into the bottom in cooling column body, and discharges from discharging opening;
(3) when by when reducing load, tuning up the aperture of the control valve regulated on pipeline, air nozzle ejection gas flow increases, and the gas of ejection forms resistance increase in cooling column body discharge outlet, and load reduces;
(4) when by when increasing load, turning the aperture of the control valve regulated on pipeline down, air nozzle ejection gas flow reduces, and the gas of ejection forms resistance reduction in cooling column body discharge outlet, and load increases.
The advantage of this programme is: in this programme, make use of the ducted wind of contrary wind own in cooling device dexterously, have additional and regulate pipeline and air nozzle, thus the discharging of cooling column body discharge outlet is regulated, feed can be avoided to block discharging regulating structure by jet mode adjusting discharge capacity, and not need cleaning.In addition, treating that the feed of discharging may be deposited in discharge outlet, make discharging opening blocked, now, only needing by opening control valve, by air nozzle ejection gas, the feed being blocked in discharge outlet is washed open, so just can play the effect of dredging.
Prioritization scheme 1, to the further optimization of base case, each air nozzle is connected to cooling column body discharge outlet by universal joint, also comprises the angle regulating air nozzle, make the jet direction of air nozzle be inclined upwardly 5 °-10 ° before step 1.The air nozzle of such scheme can adjusting angle arbitrarily, and the gas that air nozzle sprays from air nozzle is also inclined upwardly, and can form larger resistance like this, but if the angle tilted is less than 5 °, the resistance of formation is less than normal; If it is less that the angle tilted is greater than 10 ° of areas forming resistance.
Prioritization scheme 2, to the further optimization of base case and any one of prioritization scheme 1, be also provided with controller, described control valve is electrically-controlled valve, and this electrically-controlled valve is electrically connected with controller; Comprise the following steps after step 2: when controller receives the signal needing to reduce load, the aperture that controller controls electrically-controlled valve increases, and the gas flow of air nozzle ejection increases, and the gas of ejection forms resistance to feed and increases, to reduce load; When controller receives the signal needing to increase load, the aperture that controller controls electrically-controlled valve reduces, the corresponding reduction of gas flow of air nozzle ejection, forms resistance reduce, to increase load from the gas of air nozzle ejection to feed.In such scheme, automatically adjusted to electrically-controlled valve by controller, the promptness of adjustment and accuracy are all higher.
