Technical Field

The invention relates to the technical field of amino acid chelated fertilizers, in particular to a full-automatic internal circulation amino acid liquid fertilizer production device and a production method.

Background

The application of fertilizers in agricultural production to promote plant growth, increase yield and improve plant quality has become one of important measures, chemical fertilizers are widely applied by farmers at present, the chemical fertilizers have single components, high active ingredient content and good dispersibility, are easy to be absorbed and utilized by plants and are also called as 'quick-acting fertilizers', however, with the long-time and unreasonable application of the chemical fertilizers, the carbon-nitrogen ratio of soil is seriously disordered, the soil is hardened, the farming performance is poor, and some farmlands are even not suitable for secondary farming.

The amino acid fertilizer as a novel fertilizer can improve soil, solves the problem that the negative effects brought by chemical fertilizers are more and more widely accepted by people, particularly, the amino acid fertilizer prepared by hydrolyzing animal protein of dead livestock and poultry and slaughter wastes with diseases or unknown reasons has quick-acting function as well as chemical fertilizers, the implementation of the technical process can effectively consume the waste livestock and poultry and slaughter leftovers and produce high-quality amino acid organic fertilizer, the healthy development of upstream breeding industry can be effectively guaranteed, the production cost of the amino acid fertilizer and the bio-organic fertilizer can be greatly reduced, the development of downstream organic (class) fertilizer industry is promoted, and the sustainable cyclic utilization of resources is realized.

The chelation process of amino acid stock solution and compounds such as trace elements is accompanied with a certain amount of exothermic phenomenon, especially the exothermic reaction is violent in the feeding process, so that the temperature in the chelation tank is increased sharply. The temperature is one of the very important external conditions in the process of chelating trace elements by using the animal protein hydrolysis stock solution, and when the temperature exceeds a certain limit value, the quality of a chelated product is reduced and even the chelated product is scrapped. In addition, in the prior art, the animal proteolysis stock solution chelated trace element liquid fertilizer is generally fed by a conveying device or a high platform, namely, the material is conveyed to a chelating tank operation platform by the conveying device or a lifting device, 4-5 inorganic compounds are sequentially fed in a manual or mechanical mode according to the required amount, then a stirrer in the chelating tank is started to heat and stir, and the chelation is slowly carried out, wherein the chelation time is generally 4-6 hours. Because inorganic element has the hydroscopicity, lead to conveying equipment and high platform bonding material and be difficult for wasing and shovel off, cause the huge waste of manpower and financial resources, on the other hand is unfavorable for going on of extensive and automated production.

Disclosure of Invention

One of the objectives of the present invention is to overcome the drawbacks of the prior art, and to provide a full-automatic apparatus for producing liquid fertilizer with amino acids and internal circulations, which can gradually saturate the compounds such as trace elements in the mixed raw materials and simultaneously prevent the exothermic reaction from being too violent.

In order to achieve the technical effects, the technical scheme of the invention is as follows: the utility model provides a full-automatic inner loop amino acid liquid fertilizer apparatus for producing, includes along stoste storage tank, circulation that the material flow direction communicates in proper order dissolves feeding tank, chelate jar and produces the finished product storage tank, the top that the feeding tank was dissolved in the circulation is provided with the solid raw materials dog-house, the discharge gate of chelate jar with the feeding tank is dissolved in the circulation still through circulation feed back pipeline intercommunication. The pipeline which needs to overcome the gravity to lift the materials is connected with a lift pump.

The preferable technical scheme is that a cooling and stirring mechanism is arranged in the stock solution storage tank and/or the finished product storage tank. When the temperature in the tank is higher than a fixed value or the suspension degree of the materials is not enough, the cooling and stirring mechanism is started to fully stir the materials, so that the heat dissipation of the materials in the tank is accelerated correspondingly or the suspension degree of the materials is improved. As an equivalent alternative, it is also possible to provide stirring elements in the stock solution tank and/or the finished product tank and cooling units in the respective tank or on the pipe wall.

The cooling and stirring mechanism comprises a ventilation pipe, the ventilation pipe is communicated with an air outlet of the air blower through an air inlet pipe, and tangential ventilation holes are formed in the ventilation pipe. The wind hole of ventilation pipe is located under the liquid level, and the air current that the wind hole produced drives the liquid around the ventilation pipe and rotates around it, has the effect of accelerating heat dissipation and mixing material concurrently.

The preferable technical scheme is that a feed pipeline of the stock solution storage tank and a communicating pipeline between the chelating tank and the finished product storage tank are provided with filter components. Specifically, a coarse filter is arranged on a feed pipeline of the stock solution storage tank, and a fine filter is arranged on a communicating pipeline between the chelating tank and the finished product storage tank. The coarse filter and the fine filter are both filter devices for solid-liquid separation. Furthermore, in order to prevent the filter device from being blocked, a backflushing pipeline is further communicated with the filter assembly and comprises a single-backflushing liquid inlet pipe and a backflushing liquid outlet pipe, and backflushing fluid in the filter assembly is opposite to the flow direction of normal filtered fluid.

The preferable technical scheme is that a heating unit is arranged in the chelating tank or on the wall of the chelating tank. The heating unit can promote the material temperature in the chelate jar, promotes going on of compound and amino acid stoste chelation reaction such as microelement. The heating unit is a known component, and the selection range includes but is not limited to a steam pipe, an electric heating unit, a heat conduction oil pipe and a heating jacket.

The jacket is used for heating and cooling, and the flow directions of the heating medium and the cooling medium in the jacket are opposite. When the cooling state of the chelating tank is switched to the heating state, the heating medium with higher temperature rises to the top of the jacket, and the cooling medium is driven to be discharged through the lower opening; when chelate jar heating state switches to cooling state, because the requirement for chelate reaction ambient temperature is high, consequently cold and hot medium switching time need tend to shorten the control, and coolant is detained at the clamp cover top by the feeding of clamp cover bottom, and part heating medium is detained in the actual production, derives this part heating medium through the overflow pipe, can reach rapid cooling's effect.

The compounds such as trace elements are generally inorganic fertilizers, are usually easy to dissolve in water, are easy to absorb moisture in the air to damp and agglomerate, and are blocked by using conveying equipment and lifting equipment, particularly in rainy days, and the damp performance of materials causes the belt or the spiral wall to be more viscous and thicker, so that equipment fails. The preferable technical scheme is that the circulating dissolving feeding tank is arranged in a pit, a solid raw material feeding mechanism is arranged on the ground, and the solid raw material feeding mechanism is connected with a solid raw material feeding port. The distance between the feed inlet and the solid raw material feeding mechanism can be shortened by the structure. Furthermore, the solid raw material feeding mechanism is an electronic metering conveying device suitable for solid materials, such as a spiral electronic scale, and a discharge port is in full-sealed flexible connection with a feed port of the circulating dissolving and feeding tank. Furthermore, the chelating tanks are added in parallel in a limited amount of modularization, and 6-20 chelating tanks can be circulated by one circulating dissolving feeding tank and the solid raw material feeding mechanism, so that large-scale automatic production is facilitated, feeding points of inorganic elements and exposure points in air can be reduced as far as possible, the feeding flow is shortened, the labor input and bonding waste are reduced, and the feeding mechanism is more convenient to clean and maintain.

The pressure of the air in the raw liquid storage tank and the finished product storage tank in the feeding process is larger than the pressure outside the tank, the pressure of the air in the tank in the discharging process is smaller than the pressure outside the tank, and the two-way breather valve can adjust the pressure inside and outside the tank in time. The stock solution storage tank, the circulating dissolving feeding tank, the chelating tank and the finished product storage tank are communicated with the deodorization system, and gas in the tanks is introduced into the deodorization system for treatment, so that the cleanness of the production environment is ensured. An exhaust pump can be arranged on an exhaust pipeline communicated with the deodorization system, so that the aim of active exhaust is fulfilled.
