Description

Technical Field

[0001] This utility model relates to the field of humic acid fertilizer production technology, specifically to a high-efficiency humic acid fertilizer production reactor. Background Technology

[0002] Humic acid fertilizer is a type of organic fertilizer. Based on its source, humic acid can be divided into two main categories: natural humic acid and artificial humic acid. Natural humic acid is formed from the decomposition of plant residues. Humic acid fertilizers mainly include ammonium humate, potassium humate, sodium humate, and compound humic acid fertilizers. Humic acid is relatively resistant to microbial decomposition, making it a slow-release organic fertilizer. It can loosen the soil, increase soil temperature, improve soil anion exchange capacity and buffering capacity, and provide a certain amount of nutrients. It is mainly used in horticulture and for high-value cash crops. With social development, the demand for humic acid can no longer be met solely through natural sources. To meet this demand, humic acid waste needs to be artificially produced. A reactor is a device used to realize this reaction process.

[0003] The humic acid fertilizer production reactor mainly uses solid raw materials such as peat (straw charcoal), lignite, weathered coal, straw and sawdust, and adds sulfuric acid to the above solids to carry out an acidification reaction to produce humic acid and calcium sulfate (solid). Finally, ammonium bicarbonate is added to neutralize the humic acid generated after the acidification reaction to form water-soluble ammonium humate (a liquid form of high-efficiency humic acid fertilizer).

[0004] However, because raw materials remain on the inner wall of the reactor during mixing, water can only be added to clean it after the material is discharged. The water is then stirred inside by an agitator to clean the inner wall, but this cleaning method is not very effective. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-efficiency humic acid fertilizer production reactor to solve the technical problem of the difficulty in cleaning the inside of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency humic acid fertilizer production reactor, comprising a reaction tank, a reaction cone, a water storage tank, and a discharge port. The reaction cone is located at the bottom of the reaction tank, and a support leg is fixed to the bottom of the reaction cone. The water storage tank is fixedly installed at the top of the reaction tank. A rotating rod is installed inside the reaction tank, passing through the water storage tank and connected to it via a bearing. A motor is fixed to the end of the rotating rod, and multiple sets of mounting rods and connecting rods are fixedly installed on the outer wall of the rotating rod. A square scraper is connected to one end of the mounting rod, and one side of the square scraper is in contact with the inner wall of the reaction tank. A stirring blade is provided on the outer wall of the connecting rod, and the stirring blade is V-shaped. A fixing rod is fixedly connected to the bottom of the rotating rod, and a scraper is provided at the top of the fixing rod, with one side of the scraper in contact with the inner wall of the reaction cone. A scraper blade is installed on the bottom side of the scraper.

[0007] By adopting the above technical solution, the stirring blades inside the reaction tank stir and mix the solid raw materials and water to obtain a mixed solution. At the same time, the V-shaped stirring blades increase the contact area between the stirring blades and the liquid, making the mixing more thorough. The added square scrapers and scrapers remove the sticky substances adhering to the inner walls of the reaction tank and reaction cone, allowing the sticky substances to continue to be stirred and mixed. In addition, when cleaning the inside of the reaction tank in the future, the square scrapers and scrapers can also scrape off dirt from the inner walls of the reaction tank and reaction cone, facilitating the cleaning of the inside of the device.

[0008] The present invention is further configured such that the top of the water storage tank is provided with a feed inlet, and a cover plate is movably installed on the top of the feed inlet, and the bottom of the reaction cone is provided with a discharge outlet.

[0009] By adopting the above technical solution, the top and bottom of the device are respectively provided with a feed inlet and a discharge outlet, which facilitates the feeding and discharging of materials into the device. At the same time, the cover plate installed on the top of the feed inlet covers the feed inlet to prevent a large amount of dust particles generated during the mixing process from floating out of the device and causing certain harm to personnel and the environment.

[0010] The present invention is further configured such that a discharge control pipe is movably connected inside the discharge port, and the discharge port is threadedly connected to the discharge control pipe, and a filter plate is fixedly installed inside the discharge control pipe.

[0011] By adopting the above technical solution, during discharge, the filter plate installed inside the discharge control pipe filters the discharged high-efficiency humic acid fertilizer solution, separating the solid particles produced by the reaction from the high-efficiency humic acid fertilizer solution, which facilitates the subsequent production process of the high-efficiency humic acid fertilizer solution. At the same time, the discharge port and the discharge control pipe are threadedly connected. After the solution is discharged, the discharge control pipe can be removed from the discharge port to discharge the remaining reaction product particles, which facilitates the cleaning of the inside of the device.

[0012] The present invention is further configured such that a water inlet is installed at the top of the water storage tank, multiple sets of water flow holes are provided inside the water storage tank, a guide plate is fixed at the bottom of the water storage tank, and the end of the guide plate is close to the inner wall of the reaction vessel.

[0013] By adopting the above technical solution, the water in the storage tank flows to the guide plate through multiple sets of water flow holes. The guide plate guides the water to the inner wall of the reaction tank, allowing the water to flow down the inner wall of the reaction tank, which increases the contact area between the solid raw materials and the water, enabling them to mix quickly. At the same time, during the cleaning process, the water guided by the guide plate rinses the inner wall of the reaction tank, resulting in a better cleaning effect on the inner wall.

[0014] The present invention is further provided that the top of the water storage tank is provided with an exhaust port, and the bottom of the exhaust port is shaped like a horn.

[0015] By adopting the above technical solution, the bottom of the exhaust port is set in a funnel shape, which facilitates the collection of gas at the bottom of the exhaust port. At the same time, the exhaust port discharges the gas generated by the reaction inside the device, reducing the internal gas pressure and reducing the production safety hazards of the device.

[0016] The present invention is further configured such that a drain pipe is provided on the top of the water storage tank, and a pipe cap is movably installed on the top of the drain pipe. A conduit is connected to the bottom of the drain pipe, and the upper part of the conduit is configured as a funnel shape. The end of the conduit is fitted with a rotating rod, and the diameter of the drain pipe is four times the diameter of the end of the conduit.

[0017] By adopting the above technical solution, the top of the conduit is funnel-shaped, which makes it less likely to spill when personnel pour the solution into it. The diameter of the discharge pipe is larger than the diameter of the conduit, which can reduce the flow rate of the solution. At the same time, the end of the conduit is in contact with the rotating rod, so that the solution can flow down along the outer wall of the rotating rod and slowly come into contact with the raw material solution to react, avoiding violent reactions.

[0018] The present invention is further provided that a cap is movably installed at the top of the discharge tube, and both the discharge tube and the cap are made of glass.

[0019] By adopting the above technical solution, the reaction solution is concentrated sulfuric acid, which is highly corrosive. Glass items do not react with concentrated sulfuric acid, so using glass for the drain pipe and the cap can extend the service life of the device. At the same time, the cap seals the drain pipe to prevent backflow of the solution due to excessive gas pressure inside the device.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model solves the problems of traditional humic acid fertilizer production reactors, such as inconvenient internal cleaning, easy formation of cleaning dead corners, and accumulation of solid substances left over from the reaction that affect reaction efficiency, by setting up a reaction cone, water storage tank, guide plate, square scraper, scraper, scraper blade, and filter plate. The filter plate blocks the solid substances produced by the reaction. After the liquid substances in the reaction tank are drained, the discharge control pipe is removed to discharge the reaction solids, avoiding their long-term accumulation in the reaction tank and reducing the reaction efficiency between raw materials. At the same time, during cleaning, the water in the water storage tank washes the inner wall of the reaction tank through the guide plate, thereby increasing the cleaning effect of the internal device. In addition, the square scraper and scraper blade on the rotating rod remove sticky substances on the inner wall of the reaction tank and reaction cone, which facilitates the cleaning of dirt in the tank and increases the service life of the production device.

[0022] 2. This utility model improves the mixing efficiency of raw materials in the reaction tank by setting up a liquid discharge pipe, stirring blades, conduit, and guide plate. The guide plate directs water to the inner wall of the reaction tank, thereby increasing the water spraying area and the contact area between solid raw materials and water. At the same time, the large surface area of ​​the stirring blades increases the contact between the stirring blades and the mixing liquid, resulting in better mixing between raw materials. Finally, the bottom end of the conduit is in close contact with the outer wall of the rotating rod, and the inner diameter of the conduit is small, which reduces the flow rate of sulfuric acid inside, thus reducing its flow rate and preventing violent reactions when a large amount of sulfuric acid comes into contact with the mixed liquid, thereby reducing production safety hazards.

A scraper blade 20 is installed on the bottom side of the scraper 19. The stirring blade 15 provided inside the reaction tank 1 stirs and mixes the solid raw materials and water to obtain a mixed solution. At the same time, the stirring blade 15 is V-shaped to increase the contact area between the stirring blade 15 and the liquid, so that the mixing is more thorough. The square scraper blade 16 and the scraper 19 are provided to remove the sticky substances adhering to the inner wall of the reaction tank 1 and the reaction cone 2, so that the sticky substances can continue to be stirred and mixed. In addition, when cleaning the inside of the reaction tank in the future, the square scraper blade 16 and the scraper blade 19 can also scrape off the dirt from the inner wall of the reaction tank 1 and the reaction cone 2, which facilitates the cleaning of the inside of the device.

[0032] Please see Figure 1 and Figure 2 The top of the water storage tank 3 is provided with a feed inlet 12, and a cover plate 13 is movably installed on the top of the feed inlet 12. The bottom of the reaction cone 2 is provided with a discharge outlet 5. The top and bottom of the device are respectively provided with a feed inlet 12 and a discharge outlet 5, which facilitates personnel to add and remove materials into the device. At the same time, the cover plate 13 installed on the top of the feed inlet 12 covers the feed inlet 12 to prevent a large amount of dust particles generated during the device's stirring from floating out of the device and causing a certain amount of harm to personnel and the environment.

[0033] Please see Figure 5The discharge port 5 is internally connected to a discharge control pipe 23, and the discharge port 5 is threadedly connected to the discharge control pipe 23. A filter plate 24 is fixedly installed inside the discharge control pipe 23. During discharge, the filter plate 24 installed inside the discharge control pipe 23 filters the discharged high-efficiency humic acid fertilizer solution, separating the solid particles produced by the reaction from the high-efficiency humic acid fertilizer solution, which facilitates the subsequent production process of the high-efficiency humic acid fertilizer solution. At the same time, the discharge port 5 and the discharge control pipe 23 are threadedly connected. After the solution is drained, the discharge control pipe 23 can be removed from the discharge port 5 to discharge the remaining reaction product particles, which facilitates the cleaning of the inside of the device.

[0034] Please see Figure 4 The top of the water storage tank 3 is equipped with a water inlet 9. The interior of the water storage tank 3 is provided with multiple sets of water flow holes 22. The bottom of the water storage tank 3 is fixed with a guide plate 25, and the end of the guide plate 25 is close to the inner wall of the reaction tank 1. The water in the water storage tank 3 flows onto the guide plate 25 through the multiple sets of water flow holes 22. The guide plate 25 guides the water to the inner wall of the reaction tank 1, allowing the water to flow down the inner wall of the reaction tank 1, increasing the contact area between the solid raw materials and the water, so that they can be mixed quickly. At the same time, when the cleaning device is used, the water guided by the guide plate 25 washes the inner wall of the reaction tank 1, making the cleaning effect of the inner wall better.

[0035] Please see Figure 3 The top of the water storage tank 3 is provided with an exhaust port 8, and the bottom of the exhaust port 8 is shaped like a horn. The bottom of the exhaust port 8 is shaped like a horn to facilitate the collection of gas at the bottom of the exhaust port 8. At the same time, the exhaust port 8 discharges the gas generated by the reaction inside the device, reducing the internal gas pressure and reducing the production safety hazards of the device.

[0036] Please see Figure 3 The top of the water storage tank 3 is equipped with a drain pipe 6, and a pipe cap 7 is movably installed at the top of the drain pipe 6. The bottom of the drain pipe 6 is connected to a conduit 21, and the upper part of the conduit 21 is funnel-shaped. The end of the conduit 21 is in contact with the rotating rod 14. The diameter of the drain pipe 6 is four times the diameter of the end of the conduit 21. The top part of the conduit 21 is funnel-shaped, so that it is not easy to spill when personnel pour the solution into it. The diameter of the drain pipe 6 is larger than the diameter of the conduit 21, which can reduce the flow rate of the solution. At the same time, the end of the conduit 21 is in contact with the rotating rod 14, so that the solution can flow down along the outer wall of the rotating rod 14 and slowly contact and react with the raw material solution, avoiding violent reaction.

[0037] Please see Figure 1The top of the drain pipe 6 is movably fitted with a cap 7, and both the drain pipe 6 and the cap 7 are made of glass. The reaction solution is concentrated sulfuric acid, which is highly corrosive. Glass does not react with concentrated sulfuric acid, so using glass for the drain pipe 6 and the cap 7 can extend the service life of the device. At the same time, the cap 7 seals and covers the drain pipe 6 to prevent backflow of the solution due to excessive gas pressure inside the device.

[0038] The working principle of this utility model is as follows: When using the high-efficiency humic acid fertilizer production reactor, the cover plate 13 is flipped open, and the solid raw materials are poured in from the feed inlet 12. The motor 11 is turned on to start running, and at the same time, the water pipe valve is opened to start sending water to the water outlet 9. The water entering the water storage tank 3 flows out from multiple sets of water outlets 22 and sprinkles onto the guide plate 29. The guide plate 29 guides the water to the inner wall of the reaction tank 1. The water flows down the inner wall of the reaction tank 1 and comes into contact with the solid raw materials. The motor 11 drives the rotating rod 14 to rotate. The stirring blade 15, square scraper 16, scraper 19 and scraper 20 fixed on the rotating rod 14 start to stir and mix the mixture of solid raw materials and water. The stirring blade 15 fully stirs the mixture of raw materials and water in the middle part of the reaction tank 1, while the scraper 19 and scraper 20 stir the mixture at the bottom of the reaction tank 1. At the same time, the square scraper 16 and scraper 19 stir the mixture in the reaction tank 1 and the reaction cone 2 respectively. The sticky substances generated during the mixing of raw materials on the wall are scraped off. When the solid raw materials and water are fully mixed, the pipe cover 7 is opened and sulfuric acid is slowly poured into the discharge pipe 6. The sulfuric acid entering the discharge pipe 6 flows along the guide tube 21 to the outer wall of the rotating rod 14, thus coming into slow contact with the raw material mixture in small amounts. The stirring device stirs and mixes it, and a chemical reaction occurs. The solid particles produced by the reaction are concentrated at the bottom of the reaction cone 2. The gas produced by the reaction is discharged and collected from the exhaust port 8. Then, ammonium bicarbonate crystals are added to the mixture in the reaction tank 1 from the feed port 12 and stirred and reacted to produce liquid high-efficiency humic acid fertilizer. The rotating scraper 20 will push aside the solid particles of the reaction product concentrated on the surface of the filter plate 24, so that the liquid high-efficiency humic acid fertilizer can flow out through the filter holes on the filter plate 24. Finally, the liquid high-efficiency humic acid fertilizer is discharged from the discharge port 5 by controlling the discharge control pipe 23.

[0039] When the device needs cleaning, manually rotate the discharge control pipe 23 to remove it from the discharge port 5, and clean out the solid particles generated by the reaction from the discharge port 5. Then, start sending water to the water inlet 9. The water enters the water storage tank 3 and flows to the guide plate 25. The guide plate 25 guides the water to the inner wall of the reaction tank 1 to rinse the inner wall of the reaction tank 1. When the reaction tank is full of water, turn on the motor 11 to start operation. The stirring blade 15 starts to stir the water to clean all the internal components of the device. At the same time, the square scraper 16 and the scraper 19 scrape off the sticky substances generated during the mixing of raw materials on the inner wall of the reaction tank 1 and the reaction cone 2, respectively. Finally, the waste liquid obtained from rinsing is discharged from the discharge port 5.
