Description

Technical Field

[0001] This utility model relates to the field of water-soluble fertilizer storage technology, and more specifically, to a storage tank for storing water-soluble fertilizer with protective function. Background Technology

[0002] Water-soluble fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. It can dissolve quickly in water, making it easier for crops to absorb. Moreover, its absorption and utilization rate is relatively high. More importantly, it can be applied to facility agriculture such as sprinkler and drip irrigation to achieve integrated water and fertilizer management, thus saving water, fertilizer and labor.

[0003] Existing water-soluble fertilizer storage tanks are fixed in one place and cannot be moved. In addition, the storage tanks have no protective measures. After the tank is hit by external impact, the tank will be damaged, causing the water-soluble fertilizer to spill on the ground and resulting in unnecessary waste.

[0004] A search revealed that Chinese Patent No. CN214777960U discloses a storage tank for storing water-soluble fertilizer with protective function. The device is connected to the support column by a moving mechanism and fixed to the first tank body by a fixing block, which facilitates the movement of the device and makes the first tank body more stable, thus providing a certain degree of protection.

[0005] However, in actual use, when operators need to add or remove materials from the storage tank, the air pressure inside and outside quickly equalizes when the lid is opened. At this time, the humid air from outside will enter the tank, causing the air to oxidize and deliquesce with the water-soluble fertilizer, thus affecting the storage effect of the water-soluble fertilizer. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a storage tank for storing water-soluble fertilizer with protective function, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A protective storage tank for water-soluble fertilizer includes a tank body and a base column fixedly connected to the bottom of the tank body. A tank cover is provided on the top of the tank body, and a door is hinged to the inside of the cover. A discharge pipe is provided at the bottom of the tank body, and a solenoid valve is provided inside the discharge pipe. A pressure sensor is provided inside the cover, and the sensing end of the pressure sensor extends to the inside of the tank body. A micro-pressure protection mechanism is provided on the outside of the tank body. The micro-pressure protection mechanism includes a positioning frame fixedly connected to the surface of the tank body, a nitrogen tank is provided inside the positioning frame, and a gas pipe is connected to the top of the nitrogen tank. An air pump is fixedly connected to the outside of the tank body, the input end of the air pump is connected to the end of the gas pipe, and the output end of the air pump is connected to... The tank is equipped with a second air pipe, one end of which is connected to the tank lid at the top of the tank body. A shell is fixedly connected to the surface of the tank lid, and the shell is in communication with the surface of the tank lid. The shell has a conical cross-section, and a support is fixedly connected to the inner surface of the shell. The support has a through hole running vertically through its surface. A sealing seat is slidably connected to the outer side of the support. The sealing seat has a conical cross-section matching the shell cross-section. Three rubber rings are fixedly connected to the outer surface of the sealing seat, and the three rubber rings are evenly distributed along the conical outer surface of the sealing seat. A pressure rod is fixedly connected to the top of the sealing seat, and a disc is fixedly connected to the outer side of the pressure rod. A spring is installed between the disc and the shell. A stirring mechanism is installed inside the tank body.

[0008] By adopting the above technical solution, controllable air circulation can be achieved between the inside and outside of the tank using the outer shell and sealing seat. Then, the gaps inside the tank are filled by the nitrogen tank, air pipe one, air pump and air pipe two, so that the air is discharged and the water-soluble fertilizer is separated from the air.

[0009] As a further description of the above technical solution: the agitation mechanism includes a rotating shaft rotatably connected to the inside of the tank, and the top end of the rotating shaft passes through the top of the tank lid and extends above the lid. A servo motor for driving the rotating shaft to rotate is provided on the upper surface of the lid. Two agitators and a spiral disk are fixedly connected to the outside of the rotating shaft, and the two agitators and the spiral disk are distributed from top to bottom on the surface of the rotating shaft. The two agitators are rotatably distributed on the surface of the rotating shaft with the rotating shaft as the center. Multiple arc-shaped scrapers are fixedly connected between the two agitators.

[0010] By adopting the above technical solution, two agitators and multiple arc-shaped scrapers are used in combination with a spiral disc to fully agitate the water-soluble fertilizer inside the tank. At the same time, the spiral disc can assist in the feeding of the water-soluble fertilizer.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up a micro-pressure protection mechanism, compared with the existing technology, the tank can complete the repeated nitrogen filling and exhaust replacement process by using air pipe one, air pump and air pipe two in conjunction with the outer shell and sealing seat. This process exhausts the air in the tank and fills the tank with nitrogen to complete the seal, eliminating oxygen and moisture. At the same time, a micro-pressure environment is formed inside the tank, thereby creating an internal and external pressure difference. This effectively prevents external humid air from flowing back in when the lid is opened, and effectively delays the oxidation and deliquescence of water-soluble fertilizers. 2. By setting up an agitation mechanism, compared with the existing technology, the water-soluble fertilizer can be agitated multiple times by using two rotating agitators and multiple arc-shaped scrapers. This can better break up the clumps in various corners of the water-soluble fertilizer and improve the storage effect of the tank on the water-soluble fertilizer. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The embodiments disclosed in this application are as follows: Figures 1-7 The water-soluble fertilizer storage tank with protective function shown includes a tank body 1 and a bottom column 2 fixedly connected to the bottom of the tank body 1. A tank cover is provided on the top of the tank body 1, and a tank cover door 3 is hinged to the inside of the cover. A discharge pipe 4 is provided at the bottom of the tank body 1, and a solenoid valve is provided inside the discharge pipe 4. A pressure sensor 5 is provided inside the cover, and the bottom end of the pressure sensor 5 extends to the inside of the tank body 1. A micro-pressure protection mechanism is provided on the outside of the tank body 1. The micro-pressure protection mechanism includes a positioning frame 6 fixedly connected to the surface of the tank body 1, a nitrogen tank 7 is provided inside the positioning frame 6, and a gas pipe 8 is connected to the top of the nitrogen tank 7. An air pump 9 is fixedly connected to the outside of the tank body 1. The input end of the air pump 9 is connected to the end of the gas pipe 8, and the output end of the air pump 9 is connected to a second gas pipe 10. One end of pipe 10 is connected to the lid of the tank body 1; the lid of the tank body 1 is fixedly connected to the outer shell 11, and the outer shell 11 is connected to the lid surface. The outer shell 11 has a conical cross section, and a bracket 12 is fixedly connected to the inner surface of the outer shell 11. The bracket 12 has a through hole running vertically through the surface. A sealing seat 13 is slidably connected to the outer side of the bracket 12. The sealing seat 13 has a conical cross section that matches the cross section of the outer shell 11. Three rubber rings are fixedly connected to the outer surface of the sealing seat 13, and the three rubber rings are evenly distributed along the conical outer surface of the sealing seat 13. A pressure rod 14 is fixedly connected to the top of the sealing seat 13. A disc is fixedly connected to the outer side of the pressure rod 14, and a spring 15 is provided between the disc and the outer shell 11. An agitation mechanism is provided inside the tank body 1. Nitrogen gas is continuously injected into the tank 1 using nitrogen tank 7, gas pipe 1 8, air pump 9, and gas pipe 2 10. Combined with the flow of gas through the outer shell 11 and sealing seat 13, the nitrogen gas can squeeze out the air, so that the tank 1 can be effectively filled with nitrogen gas, thereby isolating the air from the water-soluble fertilizer. At the same time, the pressure sensor 5 is used to detect the air pressure inside the tank 1, so that the air pump 9 can continuously inject a small amount of nitrogen gas under a low-pressure environment, thereby reducing the air entry caused by opening and closing the tank cover door 3.

[0022] Reference Figure 1 and Figure 5As shown, the agitation mechanism includes a rotating shaft 16 rotatably connected to the inside of the tank body 1, with the top end of the rotating shaft 16 penetrating through the tank cover at the top of the tank body 1 and extending above the tank cover. A servo motor 20 for driving the rotating shaft 16 to rotate is provided on the upper surface of the tank cover. Two agitator frames 17 and a spiral disk 19 are fixedly connected to the outside of the rotating shaft 16, and the two agitator frames 17 and the spiral disk 19 are distributed from top to bottom on the surface of the rotating shaft 16. The two agitator frames 17 are rotatably distributed on the surface of the rotating shaft 16 with the rotating shaft 16 as the center. Multiple arc-shaped scrapers 18 are fixedly connected between the two agitator frames 17. The agitation frequency of the water-soluble fertilizer can be increased by using the two rotating agitator frames 17 and the multiple arc-shaped scrapers 18 on their surfaces, while expanding the agitation range, thereby effectively breaking up the clumps formed inside the water-soluble fertilizer. The spiral disk 19 is used to increase the agitation range of the water-soluble fertilizer and assist in feeding.

[0023] The working principle of this utility model is as follows: When storing water-soluble fertilizer, first open the can lid door 3 on the surface of the can lid and place the water-soluble fertilizer into the inside of the can body 1. After the water-soluble fertilizer is filled into the can body 1, close the can lid door 3 again and start the air pump 9 to input the nitrogen gas inside the nitrogen tank 7 into the inside of the can body 1 through the air pipe 8 at the input end and the air pipe 10 through the can lid. Then, the operator presses the pressure rod 14 to drive the disc to squeeze the spring 15 to deform and contract, thereby causing the pressure rod 14 to push the sealing seat 13 and carry the three rubber rings to separate from the inner surface of the outer shell 11. At the same time, the support 12 guides the sealing seat 13 so that the sealing seat 13 can move vertically up and down on the inner surface of the outer shell 11, thereby connecting the air inside and outside the can body 1 through the outer shell 11. After nitrogen is continuously supplied into the tank 1 via nitrogen tank 7, air pipe 1 8, air pump 9, and air pipe 2 10, the nitrogen compresses the air inside the tank 1, pushing it upwards. This causes the air to escape through the gap between the outer shell 11 and the sealing seat 13. Then, the operator releases the pressure rod 14. It is worth noting that after the spring 15 loses its thrust, it will elastically deform and push the pressure rod 14 and the disc, causing the sealing seat 13 and the three rubber rings to make multiple contacts with the inner surface of the outer shell 11, thus sealing the outer shell 11 and the sealing seat 13. This allows nitrogen to fill the gaps between the water-soluble fertilizer and the tank 1, reducing the reaction between the nitrogen and the fertilizer, thereby achieving the effects of moisture prevention and oxidation prevention. At the same time, the pressure sensor 5 can detect the air pressure inside the tank 1, and the external PLC controller can control the amount of nitrogen delivered by the air pump 9, so that the inside of the tank 1 can always maintain a low air pressure, thereby reducing the amount of air entering when the tank cover door 3 on the top of the tank 1 is opened and closed. During the long-term storage of water-soluble fertilizer, the servo motor 20 can drive the rotating shaft 16 to rotate inside the tank 1, so that the rotating shaft 16 drives two agitators 17, multiple arc-shaped scrapers 18 and spiral disc 19 to effectively agitate the water-soluble fertilizer inside the tank 1, so as to prevent the water-soluble fertilizer from clumping. Finally, when it is necessary to output the water-soluble fertilizer, the solenoid valve inside the tank cover door 3 is opened first, and then the water-soluble fertilizer is output through the discharge pipe 4 under the continuous rotation of the spiral disc 19.
