Description

Technical Field

[0001] The utility model relates to the field of organic fertilizer production, in particular to a mobile organic fertilizer production device which uses organic wastes such as livestock and poultry manure, kitchen waste, slaughterhouse waste, septic tank sludge, etc. as raw materials. Background Technique

[0002] Organic wastes are rich in substances such as carbon, nitrogen, and phosphorus. Organic fertilizers have comprehensive nutrients and a long fertilizer efficiency period. They can improve soil structure, increase soil fertility, reduce secondary salinization of the soil, increase the yield and quality of vegetables, reduce soil-borne diseases of crops, and increase the types of beneficial microorganisms in the soil. The traditional rural technology is to use anaerobic and aerobic fermentation to treat organic wastes. This technology generally takes 2-3 months for anaerobic digestion and composting, with low efficiency. In addition, at present, many organic fertilizer productions mainly rely on manual labor when collecting and treating livestock manure. The method is too simple and requires heavy manual labor. Using an organic fertilizer production device can improve productivity and reduce labor. CN113683442A discloses a mobile organic fertilizer production device, in which the organic fertilizer production device loaded on a truck has a relatively complex process. In order to simplify its process, the utility model has made several optimizations. Content of the Utility Model

[0015] The following further elaborates on the present utility model in conjunction with the attached drawings and technical solutions.

[0016] Figure 1 A mobile organic fertilizer production device installed in the chassis (2) of a truck (1) is shown. This mobile organic fertilizer production device includes a manure suction pump (20) to collect organic waste into the mixing reaction chamber (10), and then the mixing reaction chamber (10) is used to mix the organic waste and additives. The additive supply device includes a belt conveyor (30) and an additive medicine box (60). The exhaust gas duct (40) of the truck is connected to the muffler (3), and the exhaust gas enters the mixing reaction chamber (10) and is further absorbed. The organic fertilizer produced in the mixing reaction chamber (10) is emptied through a discharge pump (50).

[0017] In addition to the above-mentioned mobile production equipment body, the equipment can also be matched with a dryer, a granulator, a storage bin, and an open space for natural drying.

[0018] Preferably, the battery (4) of the truck (1) and the engine are connected to a power converter (not shown in the figure) to supply power to the reaction chamber (10), the manure suction pump (20), the belt conveyor (30), and the discharge pump (50). The belt conveyor support (33) is connected between the truck chassis (2) and the belt conveyor (30) for fixation. The rotation of the belt conveyor is powered by a belt motor (31) and a belt drive chain (32). Optionally, the power supply device can be installed on the truck chassis.

[0019] The organic waste in the mixing reaction chamber is fully mixed by the paddles (14) installed on the mixing shaft (15), and the mixing motor (13) provides power. There are a manure suction pipe (11) and an additive feed inlet (16) at the upper part of the mixing reaction chamber (10), and a discharge pipe (12) for discharging the organic fertilizer at the lower part. The optimal operating speed of the mixing reaction chamber is 1 - 30 rpm. Optionally, the reaction chamber can be selected as paddle type or spiral type according to the specific characteristics of the organic matter and environmental conditions.

[0020] The manure pump (20) is installed in the middle of the manure suction pipe (11) to pump the organic waste into the mixing reaction chamber (10). Optionally, a screen can be added to the end of the manure suction pipe to prevent impurities such as wood, plastic, and fabric from being pumped into the reaction chamber if the waste contains them. First, additives such as quicklime, lightly burned dolomite, and lightly burned magnesite are added to the mixing reaction chamber (10). Based on the solid weight of 100 parts of the organic material, the added weight of quicklime is 5 to 10 parts (the additives can be manually placed from the additive medicine box onto the conveyor belt).

[0021] In addition, the additives in the additive medicine box (60) include the following types:

[0022] 1. Silicate, which is a mixture of wollastonite powder and iron-smelting by-product slag and can be used for rice planting; 2. Carbon-based additives, namely charcoal and activated carbon, are used to promote plant growth;

[0023] 3. Clay minerals are used to provide nitrogen nutrient elements;

[0024] 4. Zeolite, diatomaceous earth, and bentonite are used to improve the soil cation exchange capacity;

[0025] 5. Sawdust is used to adjust the potassium content in the soil.

[0026] 6. In addition, to improve the deodorization effect, when adding additives, activated carbon, charcoal, zeolite, diatomaceous earth, or bentonite is added as a deodorant to the mixing reactor (10).

[0027] After adding additives such as quicklime, the mixing reaction chamber will become a strongly alkaline environment with a pH value of 11 - 13. Excessive application of such organic fertilizers may affect plants, so it is recommended to apply fertilizers appropriately according to the soil acidity. In addition, skin contact with strong alkali can also cause allergies. Therefore, to ensure safety and convenient fertilization, it is necessary to make the strong alkali organic fertilizer into a weak alkali organic fertilizer. Here, the acidic gas of the tail gas needs to be introduced into the reaction chamber.

[0028] The tail gas duct (40) is connected between the truck tail gas muffler (3) and the mixing reaction chamber (10) to introduce the tail gas into the bottom of the mixing reaction chamber (10) for absorption. The air pipe (40) can be connected and disassembled through the connector (41), and the discharge pump (50) is installed in the middle position of the discharge pipe. The waste gas is divided into tiny bubbles under the action of stirring and mixing and gas pressure in the mixing reactor (10). The CO 2 gas reacts with the ions hydrolyzed from the fertilizer to form calcium carbonate neutral salt, thereby reducing the pH value of the organic fertilizer from 11 - 13 when adding quicklime to 9 - 10 after the carbonation reaction.

[0029] When starting to work, the fecal sewage pump operates to pump the organic waste into the mixing reaction tank (10) for mixing. At the same time, the additive enters the reaction tank through the belt conveyor. The organic fertilizer can be directly discharged into the farmland in a wet state, or driven to the treatment area for subsequent treatments such as drying, granulation, storage, and shipment. To improve the fluidity and reaction efficiency of the fertilizer in the reaction tank, the water content of the inhaled organic waste is adjusted to 60 - 90% by adding water. After the truck enters the farmland, the discharge pump is turned on, and the organic fertilizer is evenly spread on the farmland through the discharge pipe. The method for manufacturing the mobile organic fertilizer includes the following steps: sucking the organic matter into the mixing reactor with a pump; adding the additive; introducing the automobile exhaust gas; undergoing the mixing hydrolysis reaction and carbonation reaction during transportation; directly spreading the organic fertilizer onto the farmland or transporting it to the processing site for drying and granulation. Under the condition of no factory, the present invention can convert the livestock and poultry manure that would cause environmental pollution into an organic fertilizer with no peculiar smell, weak alkalinity, and rich in calcium elements.

[0030] The preferred implementation of the present invention is introduced in detail below:

[0031] pH value calculation

[0032] 1 kg of fecal matter TS (solid content) = 20%, water content is 80%. Add 1 / 20 part of CaO, that is, 50 g. Water content = 800 g - (18 g - H 2 O × 50 g CaO / 56 g - CaO) = 783.93 g, Ca(OH) 2 Solubility (0.141 at water temperature 40°C, 0.121 at water temperature 60°C)

[0033] Solubility = 0.141 - [(0.141 - 0.121) × (41.55 - 40) / 20] = 0.1394 g - Ca(OH) 2 / 100 g

[0034] Therefore, the dissolved mass of Ca(OH) 2 = 783.93 × 0.1394 g - Ca(OH) 2 / 100 = 1.0928 g

[0035] Reaction formula Ca(OH) 2 —>Ca 2+ +2OH - +3.98 kcal / mol

[0036] Enthalpy expression ΔH := -129.74 + 2 × (-54.97) + 235.70 = -3.98 kcal / mol

[0037] = 1.0928 g × 2 mol OH / 74.09 g = 2.95 × 10 -2 mol

[0038] Hydroxide concentration OH - = 2.95×10 -2 mol OH / 783.93×10 3 / H 2 O = 0.03763 mol / L

[0039] pH = 14 - [-log(OH)] = 14 - (-log0.03763) = 14 - 1.4245 = 12.58

[0040] Add 1 / 20 part (5% of the manure volume) of quicklime, and the pH value is 12.58

[0041] Assume that when the quicklime addition dose for every 1 ton of manure is set at 50 kg (1000 kg × 5%), the volume of the mixing reaction tank of the truck is 6 cubic meters, and the average fuel consumption is 25 liters of diesel for 40 kilometers. It is found from the data that 25 liters of diesel combustion produces 70.59 kg of carbon dioxide gas. Therefore, the carbonation rate is 50% [(70.59 kg - CO 2 x 56 - CaO / 44 - CO 2 ) + (6 m 3 x 5% × 1000)].

[0042] The reaction chemical formula is as follows

[0043] Ca(OH) 2 + H 2 O + CO 2 -> Ca 2+ + 2OH - + CO 2 + H 2 O

[0044] -> Ca 2+ + HCO 3 - + OH - + H 2 O

[0045] -> Ca 2+ + CO 3 2- + 2H 2 O -> CaCO 3 + 2H 2 O

[0046] At this time, the pH value is 14 - [-log(OH)] = 14 - (-log0.009) = 14 - 1.9586 = 11.954

[0047] The above embodiments are merely exemplary and should not be construed as the entire content of the invention. The purpose of the description of the present invention is illustrative rather than beyond the scope of the claims. The mobile organic fertilizer production equipment includes the following steps: pumping organic matter into the mixing reaction tank with a manure pump; adding additives; introducing vehicle exhaust gas; exothermic reaction of quicklime, alkali neutralization reaction, and carbonation reaction during transportation; sprinkling the organic fertilizer on farmland or discharging it to a processing site for drying and granulation. The present invention can recycle environmental pollutants during vehicle transportation under the condition of no factory, and produce organic fertilizers that are weakly alkaline, odorless, and rich in calcium.
