Description

Technical Field

[0001] This invention relates to the field of liquid fertilizer defoaming technology, specifically to a defoaming device for liquid fertilizer production. Background Technology

[0002] Liquid fertilizers are a type of fluid agricultural fertilizer that provides all the nutrients needed for plant rooting, growth, and fruiting, including but not limited to the key elements nitrogen, phosphorus, and potassium, as well as rare trace elements and organic matter. With its uniform nutrient distribution and easy absorption by plants, this type of fertilizer can instantly replenish crop nutrients, promoting rapid crop development and increasing yields. Liquid fertilizers offer flexible application methods, including spraying onto the plant surface or delivering them directly to the roots via drip irrigation systems, simplifying operation and allowing for mixing with other agricultural chemicals such as pesticides, thus optimizing field management.

[0003] During the manufacturing process of liquid fertilizer, the mixing of various trace elements and organic matter and the dynamic stirring will cause the formation of a large amount of foam. This foam may cause blockage of the conveying and discharge systems on the production line, affecting the discharge rate, and sometimes even causing serious consequences such as complete blockage of the outlet, which greatly limits the continuity and efficiency of the production process.

[0004] Based on this, the present invention designs a defoaming device for liquid fertilizer production to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a defoaming device for liquid fertilizer production to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a defoaming device for liquid fertilizer production, comprising a liquid fertilizer stirring mechanism and a discharge mechanism, wherein the discharge mechanism is located on one side of the bottom of the liquid fertilizer stirring mechanism, and the discharge mechanism includes a pressure regulating valve for defoaming in liquid fertilizer production discharge and a first defoaming component, wherein the first defoaming component is disposed at the output end of the pressure regulating valve, and a second defoaming component is connected to the output end of the first defoaming component away from the pressure regulating valve. The first defoaming component includes an infusion tube body, an antifoaming sieve ball is provided inside one end of the infusion tube body, a baffle is provided on the inner wall of the end of the infusion tube body near the antifoaming sieve ball, and a storage tube body is also provided at an incline at the bottom of the infusion tube body; The second defoaming component includes a connecting cylinder, and a first connecting flange is installed on one side of each of the two sets of connecting cylinders. A defoaming component is also installed between the two sets of first connecting flanges.

[0007] Based on the above technical features, the defoaming device for liquid fertilizer production of the present invention mainly solves the problem of the generation of a large amount of foam in the process of liquid fertilizer production. The device consists of a liquid fertilizer stirring mechanism and a discharge mechanism. During the production and transportation of liquid fertilizer, excessive foam may cause blockage and reduced efficiency. In order to effectively solve this problem, the defoaming device designed in this invention adopts a composite structure including a pressure regulating valve and at least two stages of defoaming components. The function of the pressure regulating valve is to control the pressure of the liquid fertilizer flowing through the discharge mechanism, which helps to prevent excessive foam from being generated due to excessive pressure. The first defoaming component is located at the output end of the pressure regulating valve and helps to destroy the foam through its internal structure. Specifically, the defoaming sieve ball installed in the infusion tube can effectively break the foam flowing through the infusion tube. The storage tube at the bottom of the infusion tube can collect the filtered and overflowing foam, which can prevent the overflowing foam from being mixed back into the liquid fertilizer and avoid the foam from blocking the output end of the infusion tube due to excessive amount. This solution enhances the defoaming effect of the discharge mechanism on the production and transportation of liquid fertilizer by adding a second defoaming component to the output end of the infusion tube. This second defoaming component consists of a connecting cylinder, a first connecting flange, and defoaming parts. First, the second defoaming component, installed between the two sets of connecting cylinders, generates more turbulence during the production and transportation of liquid fertilizer, thereby further breaking down the fine foam contained in the liquid fertilizer. Furthermore, the specific structural design of the through holes on the demister screen and demister filter promotes the separation of gas and liquid, ensuring that the liquid fertilizer will not be blocked during production and transportation due to excessive fine foam. This significantly improves production efficiency and continuity. Through precise pressure control and effective defoaming structure design, the liquid fertilizer production defoaming device of this invention overcomes the limitations of traditional defoaming methods, bringing a new technical solution to the liquid fertilizer industry.

[0008] Preferably, in the above-mentioned defoaming device for liquid fertilizer production, a first annular groove is provided around the inner sides of the two sets of first connecting flanges, and a first sealing element is provided between the two sets of first annular grooves.

[0009] Based on the above technical features, this solution provides a reliable sealing interface for the defoaming device by combining the first annular groove and the first seal. When the defoaming device is in operation, the first seal expands under pressure and tightly fills the first annular groove inside the two sets of first connecting flanges. This process enhances the sealing effect and prevents leakage of liquid fertilizer.

[0010] Preferably, in the above-mentioned defoaming device for liquid fertilizer production, a second connecting flange is installed at one end of the storage tube, a fixed plate is provided on the side of the storage tube near the second connecting flange, a second annular groove is formed around the inner side of the fixed plate and the second connecting flange, and a second sealing element is provided between the two sets of second annular grooves.

[0011] Based on the above technical features, this solution adds a second seal between the two sets of second annular grooves. When the defoaming device is in operation, the second seal located between the second connecting flange and the fixed disc expands under pressure, allowing the second seal to tightly fill the second annular groove opened on the inner side of the second connecting flange and the fixed disc. This process enhances the sealing effect and can also prevent leakage of liquid fertilizer.

[0012] Preferably, in the above-mentioned defoaming device for liquid fertilizer production, the defoaming component includes a metal cylinder, and defoaming mesh plates are respectively provided at both ends of the interior of the metal cylinder.

[0013] Based on the above technical features, this solution can effectively capture and destroy air bubbles in the flowing liquid fertilizer by installing demister plates at both ends of the metal cylinder. The through holes on the demister plate are designed with a specific structure to allow the liquid fertilizer to pass through normally while blocking and capturing air bubbles. This process can significantly reduce the air bubble content in the liquid fertilizer, thereby promoting the production and transportation of purer and higher quality liquid fertilizer.

[0014] Preferably, in the above-mentioned defoaming device for liquid fertilizer production, the defoaming screen includes a metal ring, and metal clips are respectively provided on both sides of the outer side of the metal ring.

[0015] Based on the above technical features, this solution uses metal clips installed on both sides of the outer metal ring to limit and connect the demister screen to the inside of both ends of the metal cylinder.

[0016] Preferably, in the above-mentioned defoaming device for liquid fertilizer production, a defoaming filter element is provided in the middle of the inner cavity of the metal cylinder, and annular grooves are provided at both ends of the metal cylinder. Connecting slots are also provided on both sides of the metal cylinder near the annular grooves.

[0017] Based on the above technical features, this solution uses a defoaming filter element installed in the middle of the inner cavity of the metal cylinder to remove fine foam from liquid fertilizer. The defoaming filter element, through a specific structural design of the through holes, promotes the separation of gas foam from liquid while also capturing and breaking up the separated gas foam. This design ensures that the liquid is cleaner and improves the quality of the product.

[0018] Preferably, in the above-mentioned defoaming device for liquid fertilizer production, the annular slot, the connecting slot and the metal block are matched in structure, and the annular slot, the connecting slot and the metal block are in a plug-in fit.

[0019] Based on the above technical features, this solution uses a structural design that connects the annular slot, the connecting slot, and the metal block to insert and connect the defoaming screen plate to both ends of the inside of the metal cylinder. The defoaming component can also be disassembled, connected, repaired, or replaced according to the metal cylinder and the defoaming screen plate.

[0020] Preferably, in the above-mentioned defoaming device for liquid fertilizer production, the second sealing element has the same structure as the first sealing element. The second sealing element includes an annular rubber shell, an annular rubber plate is connected between the two sets of annular rubber shells, and multiple sets of compression springs are connected between the annular rubber plate and the two sets of annular rubber shells.

[0021] Based on the above technical features, the second seal in this solution has the same structure as the first seal, both consisting of an annular rubber shell, an annular rubber plate, and a compression spring. This allows the second seal and the first seal to maintain a stable sealing force when the external part of the discharge mechanism shakes or the internal pressure changes, thus maintaining good sealing performance under dynamic conditions.

[0022] Compared with the prior art, the beneficial effects of the present invention are: 1. The defoaming device for liquid fertilizer production of the present invention mainly solves the problem of excessive foam generation during the production of liquid fertilizer.

The storage tube at the bottom of the infusion tube can collect the filtered and overflowing foam, which can prevent the overflowing foam from mixing back into the liquid fertilizer and avoid the foam from clogging the output end of the infusion tube due to excessive amount. 2. This solution enhances the defoaming effect of the discharge mechanism on the production and transportation of liquid fertilizer by adding a second defoaming component at the output end of the infusion tube. This second defoaming component consists of a connecting cylinder, a first connecting flange, and defoaming parts. First, the second defoaming component, installed between the two sets of connecting cylinders, generates more turbulence during the production and transportation of liquid fertilizer, thereby further breaking down the fine foam contained in the liquid fertilizer.

The discharge mechanism 200 is located at the bottom of the liquid fertilizer stirring mechanism 100. The discharge mechanism 200 includes a pressure regulating valve 201 for defoaming in liquid fertilizer production discharge and a first defoaming component 202. The first defoaming component 202 is located at the output end of the pressure regulating valve 201. A second defoaming component 203 is also connected to the output end of the first defoaming component 202 away from the pressure regulating valve 201. The first defoaming component 202 includes a delivery pipe body 202a. A defoaming sieve ball 202b is provided inside one end of the delivery pipe body 202a. A baffle 202c is provided on the inner wall of the end of the delivery pipe body 202a near the defoaming sieve ball 202b. A storage pipe body 202d is also inclinedly provided at the bottom of the delivery pipe body 202a. The second defoaming component 203... Component 203 includes connecting cylinders 203a, with first connecting flanges 203b installed on one side of each of the two sets of connecting cylinders 203a. A defoaming component 203c is also installed between the two sets of first connecting flanges 203b. A first annular groove 203b-1 is formed around the inner sides of the two sets of first connecting flanges 203b. A first sealing element 203b-2 is also provided between the two sets of first annular grooves 203b-1. The combined use of the first annular groove 203b-1 and the first sealing element 203b-2 provides a reliable sealing interface for the defoaming device. When the defoaming device is in operation, the first sealing element 203b-2 expands under pressure and tightly fills the first annular groove 203b-1 inside the two sets of first connecting flanges 203b. This process enhances the sealing effect and prevents leakage of liquid fertilizer.

[0028] Please see Figure 5-6In the storage tube 202d, a second connecting flange 202d-1 is installed at one end. A fixed disc 202d-2 is provided on the side of the storage tube 202d near the second connecting flange 202d-1.

A second sealing element 202d-4 is also provided between the two sets of second annular grooves 202d-3. By adding the second sealing element 202d-4 between the two sets of second annular grooves 202d-3, when the defoaming device is in operation, the second sealing element 202d-4 located between the second connecting flange 202d-1 and the fixed disc 202d-2 will expand under pressure, so that the second sealing element 202d-4 can tightly fill the second annular groove. The second annular groove 202d-3 opened inside the connecting flange 202d-1 and the fixed plate 202d-2 enhances the sealing effect and prevents leakage of liquid fertilizer. The defoaming component 203c includes a metal cylinder 203c-1, with defoaming screens 203c-2 installed at both ends of the metal cylinder 203c-1. By installing defoaming screens 203c-2 at both ends of the metal cylinder 203c-1, bubbles in the flowing liquid fertilizer can be effectively captured and destroyed. The through holes on the defoaming screen 203c-2 are designed with a specific structure to allow the liquid fertilizer to pass through normally while blocking and capturing bubbles. This process can significantly reduce the bubble content in the liquid fertilizer, thereby promoting the production and transportation of purer and higher quality liquid fertilizer.

By adding the metal clips 203c-2b on both sides of the outer side of the metal ring 203c-2a, the demister screen 203c-2 can be limited and connected to the inside of both ends of the metal cylinder 203c-1. The demister filter element 203c-1a is provided in the middle of the inner cavity of the metal cylinder 203c-1, and annular grooves 203c are opened at both ends of the metal cylinder 203c-1. -1b, the metal cylinder 203c-1 is provided with connecting slots 203c-1c on both sides near the annular groove 203c-1b. The defoaming filter element 203c-1a installed in the middle of the inner cavity of the metal cylinder 203c-1 can be used to remove fine foam in the liquid fertilizer. The defoaming filter element 203c-1a promotes the separation of gas foam and liquid through a specific structural design of the through hole, and can also capture and destroy the separated gas foam. This design can ensure that the liquid is cleaner and improve the quality of the product.

[0030] Please see Figure 7-9In the design, the annular groove 203c-1b, the connecting slot 203c-1c, and the metal block 203c-2b are structurally matched, and the annular groove 203c-1b, the connecting slot 203c-1c, and the metal block 203c-2b are in a plug-in fit. Through this plug-in fit structure, the defoaming screen 203c-2 can be positioned and connected to both ends of the metal cylinder 203c-1. Furthermore, the defoaming component 203c allows for disassembly, assembly, repair, and replacement of the metal cylinder 203c-1 and the defoaming screen 203c-2. The second seal 202d-4 has the same structure as the first seal 203b-2. 2d-4 includes an annular rubber shell 202d-4a, an annular rubber plate 202d-4b connecting the two sets of annular rubber shells 202d-4a, and multiple sets of compression springs 202d-4c connecting the annular rubber plate 202d-4b and the two sets of annular rubber shells 202d-4a.

This allows the second sealing element 202d-4 and the first sealing element 203b-2 to maintain a stable sealing force when the external of the discharge mechanism 200 shakes or the internal pressure changes, thus maintaining good sealing performance under dynamic conditions.

[0031] Working Principle: The defoaming device for liquid fertilizer production of this invention mainly solves the problem of excessive foam generation during the liquid fertilizer production process. The device consists of a liquid fertilizer stirring mechanism 100 and a discharge mechanism 200. Excessive foam during the production and transportation of liquid fertilizer can lead to blockages and reduced efficiency. To effectively solve this problem, the defoaming device designed in this invention adopts a composite structure including a pressure regulating valve 201 and at least two stages of defoaming components. The function of the pressure regulating valve 201 is to control the pressure of the liquid fertilizer flowing through the discharge mechanism, which helps prevent excessive pressure from causing foam buildup. Excessive foam is generated. The first defoaming component 202 is located at the output end of the pressure regulating valve 201 and helps to break the foam through its internal structure. Specifically, the defoaming sieve ball 202b installed inside the infusion tube 202a can effectively break the foam that flows into the infusion tube 202a. The storage tube 202d at the bottom of the infusion tube 202a can collect the filtered and overflowing foam, which can prevent the overflowing foam from mixing back into the liquid fertilizer and avoid the foam from clogging the output end of the infusion tube 202a due to excessive amount. This solution, by adding a second defoaming component 203 to the output end of the infusion tube 202a, which consists of a connecting cylinder 203a, a first connecting flange 203b, and a defoaming component 203c, can further enhance the defoaming effect of the discharge mechanism 200 on the production and transportation of liquid fertilizer. First, the second defoaming component 203, by adding the defoaming component 203c between the two sets of connecting cylinders 203a, allows the liquid fertilizer to generate more turbulence during production and transportation, thereby further breaking down the fine foam contained in the liquid fertilizer. Furthermore, the specific structural design of the through holes on the demister screen 203c-2 and the demister filter element 203c-1a promotes the separation of gas and liquid, ensuring that the liquid fertilizer will not be blocked during production and transportation due to excessive fine foam, greatly improving production efficiency and continuity. Through precise pressure control and effective defoaming structure design, the liquid fertilizer production defoaming device of this invention overcomes the limitations of traditional defoaming methods, bringing a new technical solution to the liquid fertilizer industry.
