Description

Technical Field

[0001] The present invention specifically relates to a saline-alkali land improver production process and production equipment, belonging to the saline-alkali land improver production technical field. Background Art

[0002] Due to the difference in climate between the north and south of my country, the south is humid and rainy, and the soil is mostly acidic, while the north is dry and rainless, and the soil is mostly alkaline; excessively acidic or alkaline soil will reduce the effectiveness of soil nutrients to varying degrees, making it difficult to form a good soil structure, severely inhibiting the activity of soil microorganisms, and affecting the growth and development of various crops; for this reason, it is necessary to improve the soil, such as the patent authorization announcement number: CN104478634B, which discloses a method for preparing a saline-alkali land improver using nano-carbon silicon material, wherein organic matter, negative ion nano-carbon silicon solution, biological bacteria and nutrient source are sequentially added to a sealed stainless steel fully automatic mixer. The saline-alkali land improver prepared by this method contains a negative ion nano-carbon silicon solution, which neutralizes the acidity and alkali of the soil while supplementing a large amount of organic matter and an appropriate amount of Nutrient elements and beneficial biological bacteria are added to the soil for restoration and improvement, which increases the nutrients in the soil under photosynthesis, promotes the activation of plant roots, improves plant vitality, and gradually improves the soil condition. Among them, the key component of the improver is nano silicon carbon. Since nano silicon carbon carries a strong negative charge itself, it absorbs salt and alkali ions in the soil through the organic activity of nano ions to form a loose, breathable, pH-neutral isolation layer, thereby achieving the purpose of effectively improving saline-alkali land. However, in the existing production process of saline-alkali land improvers, nano silicon carbon is easily precipitated and adsorbed on organic matter, and it is impossible to fully disperse nano silicon carbon into the water solution through a stainless steel automatic agitator. Therefore, it is easy to cause inconsistent nano silicon carbon content in each packaged bottle after filling, resulting in uncontrollable product quality. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a saline-alkali land conditioner production process and production equipment, which uses water as a medium and other auxiliary ingredients to fully mix to prepare a mixed liquid in advance, and the mixed liquid is dynamically circulated. Before filling, each group of measured mixed liquid is added with accurately measured nano-silicon carbon to ensure the consistency of the nano-silicon carbon content in each packaged bottle.

[0004] The saline-alkali land improver production equipment of the present invention comprises: Support, which serves as the supporting unit of the entire production equipment; A vacuum material box, the vacuum material box is fixed on a support, a mesh partition is fixed inside the vacuum material box; a filter box is fixed on the top of the inner side of the vacuum material box, the bottom of the filter box is a filter screen structure, a sealing plate is fixed on the top of the vacuum material box, the sealing plate is provided with an emptying groove facing the filter box, a flange plate is fixed outside the emptying groove, and an emptying pipe is connected to the flange plate; a non-woven filter screen is fixed on the bottom surface of the flange plate; an electric stirrer is provided at the bottom of the vacuum material box; A nano silicon carbon feeding unit, the nano silicon carbon feeding unit comprises an air pressure feeding pipe, one end of the air pressure feeding pipe is sealed, and the other end is connected to a storage tank through a pressure feeding device; a plurality of inverted U-shaped distribution pipes are connected to the air pressure feeding pipe, and the distribution pipes penetrate the sealing plate and the partition; when the nano silicon carbon in the storage tank is fed into the air pressure feeding pipe through the pressure feeding device, and the nano silicon carbon is fed into the inside of the vacuum box through the distribution pipe, and fed into the bottom of the partition, the pressurized gas passes through the filter holes of the partition, and then enters the filter box through the filter holes at the bottom of the filter box, and then the pressurized gas is discharged through the non-woven filter screen and the exhaust pipe on the flange plate; the nano silicon carbon is temporarily stored inside the vacuum box, and intermittently stirred by an electric stirrer, so as to facilitate the unloading of the vacuum box; A material distribution component, the material distribution component comprises a row of material guide pipes connected to the bottom of the vacuum material box, a disc is arranged at the bottom of the material guide pipe, a cross-shaped valve plate is arranged inside the disc, and the side and end of the valve plate are attached to the inner wall of the disc; a plurality of material distribution shafts are fixed through the center of the valve plates; the material distribution shafts are connected to the material distribution motor through a transmission member; an air pressure pipe is arranged at the lower part of the disc, and the air pressure pipe is connected to the air source; a material distribution pipe is fixed at the bottom of the disc, and the material distribution pipe is embedded in the bottom of the support; The electric stirrer performs intermittent stirring to fully introduce the nano silicon carbon into the guide pipe and enter the inner side of the disc, thereby filling the space between the guide pipe, the disc and the valve plate. Then, the material distribution motor drives the material distribution shaft to rotate, thereby synchronously driving each valve plate to rotate synchronously. The valve plate receives the nano silicon carbon from the guide pipe and rotates to the material distribution pipe for material discharge. It needs to rotate 180°. The valve plate forms multiple sections in the disc and can isolate the guide pipe and the material distribution pipe. During material discharge and filling, the air source can be pumped into the space formed by the valve plate and the material distribution pipe through the air pressure pipe. An intermediate material tank, each of the material distribution pipes is connected to an intermediate material tank, a gas exhaust valve is provided on the top of the intermediate material tank, and a filling valve is provided on the bottom of the intermediate material tank; A mixed liquid tank, the upper part of which is connected to a mixed liquid supply tank via a liquid inlet valve; the mixed liquid tank is connected to a liquid supply pipe via a liquid inlet pump, and the liquid supply pipe is connected to an intermediate tank via a one-way valve; the intermediate tank serves as a metering tank for the mixed liquid, and can also serve as a nano-silicon-carbon ingredient receiving container for a packaged bottle, and as an independent mixing unit for a packaged bottle, to achieve precise processing and production of the saline-alkali land improver in the packaged bottle.

[0005] Furthermore, an ultrasonic oscillator is arranged outside the intermediate material tank, and an oscillating mixing system is established outside the intermediate material tank through the ultrasonic oscillator to fully mix the mixed liquid and nano-silicon carbon; the saline-alkali land improver in each packaged bottle is precisely dosed with nano-silicon carbon, the mixed liquid dynamically circulates, and the mixed liquid and nano-silicon carbon are independently mixed; the quality of the saline-alkali land improver in each packaged bottle is guaranteed.

[0006] Furthermore, the one-way valve is connected to the lower part of the intermediate material tank, and the upper part of the intermediate material tank is connected to the upper part of the mixed liquid tank through the liquid return valve; when working, the liquid inlet pump works continuously to pump the mixed liquid in the mixed liquid supply tank into the mixed liquid tank, and send the mixed liquid to the intermediate material tank through the one-way valve, the mixed liquid is continuously filled into the intermediate material tank, and the mixed liquid is pumped back into the mixed liquid tank through the liquid return valve; the dynamic flow of the mixed liquid is realized to avoid sedimentation inside the mixed liquid tank; when filling is required, the liquid inlet pump is turned off, and the excess mixed liquid is discharged into the mixed liquid tank through the liquid return valve, and finally the liquid return valve is closed to keep the mixed liquid inside the intermediate material tank. Due to the dynamic flow of the mixed liquid, the mixed liquid in the mixed liquid tank and the intermediate material tank has good consistency.

[0007] Furthermore, a liquid injection needle is connected to the bottom of the filling valve, a sealing pressure plate is penetrated through the bottom of the liquid injection needle, and an exhaust pipe is also embedded on the sealing pressure plate; the sealing pressure plate is movably pressed together with the bottle mouth of the packaging bottle; the liquid injection needle and the exhaust pipe are embedded in the inner side of the packaging bottle; when working, the sealing pressure plate is pressed against the bottle mouth of the packaging bottle, at this time, the liquid injection needle and the exhaust pipe are connected with the inner side of the packaging bottle, when the liquid injection needle is pressurized and liquid is injected, the water preparation of the saline-alkali land improver is pumped into the packaging bottle by the gas source, and the pressurized gas inside the packaging bottle is discharged through the exhaust pipe; so that the filling of the water preparation of the saline-alkali land improver is smooth.

[0008] Furthermore, the distribution pipe and the intermediate material tank are connected by a check valve. When the distribution pipe distributes materials, the gas source pressurizes the nano-silicon carbon into the intermediate material tank; when the gas source is closed, it is automatically isolated by the check valve to prevent the mixed liquid from rushing up into the distribution pipe, thereby achieving isolation between the distribution pipe and the intermediate material tank.

[0009] A saline-alkali land conditioner production process, using saline-alkali land conditioner production equipment, the process is specifically as follows: The first step is to prepare the liquid. A water medium is added into the mixed liquid feed tank, and auxiliary additives are added in sequence. The auxiliary additive component content is 100-200 g / L of amino acid and Fe+Zn≥20-40 g / L; wherein the ratio of Fe to Zn is 1-5:1; then, the stirring system of the mixed liquid feed tank is turned on to stir and mix the water medium and the auxiliary additives; The second step is the batching of nano silicon carbon. The pressure feeding equipment feeds the nano silicon carbon in the storage tank into the air pressure feeding pipe, and then feeds the nano silicon carbon into the vacuum material box through the air pressure feeding pipe and the distribution pipe, and exhausts through the partition. The pressure gas is discharged to the exhaust pipe through the filter box and the non-woven filter, and is connected to the bag dust collector through the exhaust pipe. The nano silicon carbon entering the vacuum material box is intermittently stirred and distributed by the electric stirrer, so that the nano silicon carbon is distributed to each guide pipe. The third step is to dynamically circulate the mixed liquid and supply it. The liquid inlet valve is opened, and the mixed liquid supply tank delivers the mixed liquid that has been stirred into the mixed liquid tank. Then, the liquid inlet valve is closed, and the liquid inlet pump and the liquid return valve are opened to allow the mixed liquid to flow dynamically between the mixed liquid tank and the intermediate tank. Then, the liquid inlet pump is closed, and the liquid return valve is closed with a delay, so that the mixed liquid in the intermediate tank that exceeds the liquid return valve is sent back to the mixed liquid tank; the liquid level in the intermediate tank is maintained at the set height. The fourth step is to feed nano silicon carbon. The feeding motor is started to drive the feeding shaft to rotate 90°, thereby driving the valve plate to rotate 90°. The closed chamber formed by the two adjacent valve plates and the inner wall of the disc is used as a metering chamber to meter the nano silicon carbon. When the valve plate rotates from the guide pipe to the feeding pipe, the nano silicon carbon falls into the feeding pipe. The fifth step is to mix the improver, turn on the ultrasonic oscillator, the air source and the exhaust valve, and inject the nano silicon carbon into the intermediate material tank through the pressure air source; at this time, the mixed liquid and the nano silicon carbon are fully mixed through the ultrasonic oscillator, and then the air source, the exhaust valve and the ultrasonic oscillator are closed; The sixth step is filling, which drives the support to rise and fall or the filling line of the encapsulated bottle to rise and fall; presses the sealing pressure plate against the bottle mouth of the encapsulated bottle, and embeds the injection needle and the exhaust pipe into the encapsulated bottle, turns on the gas source, pressurizes the improver in the intermediate material tank into the encapsulated bottle, and releases the filling pressure inside the encapsulated bottle through the exhaust pipe.

[0010] Furthermore, after all the improvers in the intermediate material tank are pumped into a packaging bottle, the filling valve is closed and the liquid inlet pump is turned on again; after the liquid inlet pump is turned on for a set time, the liquid inlet pump is turned off, and the mixed liquid is pumped into the filling intermediate material tank again to flush the trace nano-silicon carbon hanging on the wall and staying inside the intermediate material tank for a second time, and the filling valve and the air source are opened to fill the packaging bottle for a second time.

[0011] Compared with the prior art, the saline-alkali land improver production process and production equipment of the present invention use water as a medium and other auxiliary additives to fully mix to prepare a mixed liquid in advance, and the mixed liquid is dynamically circulated to avoid precipitation in the mixed liquid material box; the mixed liquid is metered through an intermediate material tank, and the mixed liquid and nano silicon carbon are mixed, and the nano silicon carbon is added with precisely measured nano silicon carbon for each group of metered mixed liquid, which can ensure that the nano silicon carbon content in each packaging bottle is consistent, and the improver in the packaging bottle is used in a one-time whole bottle. When using, the packaging bottle is fully shaken, and then all the solution in the packaging bottle is poured into a spray container and diluted with water, and then the packaging bottle is flushed multiple times, and the flushing water is sent to the spray container. Finally, it is evenly sprayed on the saline-alkali land through the spray container. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The one-way valve is connected to the lower part of the intermediate material tank 20, and the upper part of the intermediate material tank 20 is connected to the upper part of the mixed liquid tank 23 through the liquid return valve 28; when working, the liquid inlet pump 25 works continuously to pump the mixed liquid in the mixed liquid supply tank into the mixed liquid tank 23, and send the mixed liquid to the intermediate material tank 20 through the one-way valve, the mixed liquid is continuously filled into the intermediate material tank 20, and the mixed liquid is re-injected into the mixed liquid tank 23 through the liquid return valve 28; the dynamic flow of the mixed liquid is realized to avoid the occurrence of sedimentation inside the mixed liquid tank 23; when filling is required, the liquid inlet pump 25 is closed, and the excess mixed liquid is discharged into the mixed liquid tank 23 through the liquid return valve 28, and finally the liquid return valve 28 is closed to keep the mixed liquid inside the intermediate material tank 20.

When the valve plate rotates from the guide pipe to the feeding pipe, the nano silicon carbon falls into the feeding pipe. The fifth step is to mix the improver, turn on the ultrasonic oscillator, the air source and the exhaust valve, and inject the nano silicon carbon into the intermediate material tank through the pressure air source; at this time, the mixed liquid and the nano silicon carbon are fully mixed through the ultrasonic oscillator, and then the air source, the exhaust valve and the ultrasonic oscillator are closed; The sixth step is filling, which drives the support to rise and fall or the filling line of the encapsulated bottle to rise and fall; presses the sealing pressure plate against the bottle mouth of the encapsulated bottle, and embeds the injection needle and the exhaust pipe into the encapsulated bottle, turns on the gas source, pressurizes the improver in the intermediate material tank into the encapsulated bottle, and releases the filling pressure inside the encapsulated bottle through the exhaust pipe.

7. The process for producing a saline-alkali land conditioner according to claim 6, characterized in that: After all the improvers in the intermediate material tank are pumped into a packaging bottle, the filling valve is closed and the liquid inlet pump is turned on again; after the liquid inlet pump is turned on for a set time, the liquid inlet pump is turned off, and the mixed liquid is pumped into the filling intermediate material tank again to flush the trace amount of nano-silicon carbon hanging on the wall and staying inside the intermediate material tank for a second time, and the filling valve and the air source are opened to fill the packaging bottle for a second time.
