Abstract
Description
Technical Field
[0001] This utility model relates to the field of concentration equipment technology, and in particular to a concentration equipment for humic acid. Background Technology
[0002] In the field of humic acid production, thorough concentration of the humic acid solution is crucial to obtaining high-concentration, high-quality humic acid products. In practical applications, a humic acid concentration device typically requires the following technologies:
[0003] 1. Heating mechanism: Heat exchangers, steam coils and other equipment are used to provide heat to the humic acid solution to promote its evaporation and concentration. For example, heat exchangers transfer heat from the heat source to the humic acid solution through heat conduction, causing the water in the solution to vaporize and evaporate, thereby increasing the concentration of the humic acid solution.
[0004] 2. Stirring Mechanism: The stirring mechanism utilizes components such as a stirring paddle, stirring shaft, and drive motor to achieve stirring and mixing of the humic acid solution. The stirring paddle is mounted on the stirring shaft, which is driven by the drive motor to rotate, causing the stirring paddle to rotate in the solution. Through stirring, the solution can be heated evenly, avoiding local overheating or undercooling and ensuring uniform heating. On the other hand, it accelerates the evaporation of water on the solution surface, improving evaporation efficiency, thereby improving the efficiency and quality of the entire concentration process.
[0005] Existing humic acid concentration equipment requires a motor-driven stirring rod for stirring during operation. After concentration, it is necessary to use equipment such as a liquid pump to extract the humic acid. This not only results in high manufacturing costs, but the concentrated humic acid can also corrode the impeller of the liquid pump. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a humic acid concentration device, which solves the technical problem that existing humic acid concentration devices require a motor-driven stirring rod for stirring during use, and a pump or other equipment to extract the humic acid after concentration. This not only results in high manufacturing costs, but also causes corrosion of the impeller of the pump by the concentrated humic acid.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A humic acid concentration device includes a base, a concentration tank fixedly mounted on the base, a shunting shroud fixedly mounted on the concentration tank, a hollow rod for draining liquid rotatably mounted on the shunting shroud, stirring blades fixedly mounted on the hollow rod, an impeller ring fixedly mounted on the hollow rod, a drain pipe fixedly mounted on the concentration tank, the drain pipe and the hollow rod being rotatably connected by a labyrinth seal, a pressure pump fixedly mounted on the base, and a filling cap threaded onto the concentration tank.
[0009] Preferably, an air inlet pipe is installed between the filling cap and the pressurizing pump.
[0010] Preferably, the intake pipe and the filling cap are connected by a labyrinth seal.
[0011] Preferred: The concentration tank is equipped with a sealing cap.
[0012] Preferably, a spring is installed at the top of the sealing cap.
[0013] Preferably, a sealing gasket is installed at the bottom of the sealing cap.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. During use, unscrew the filling cap to add the humic acid to be treated into the concentration tank. Then, the bottom of the concentration tank is heated by the heating mechanism, causing the water in the humic acid to evaporate and concentrate. At this time, the impeller ring is supported by its bottom feet. The pressure pump is started and air is injected into the concentration tank through the air inlet pipe. The injected air will mix with water vapor and be discharged from the opening at the top of the base along the arc surface of the rectifier. During the discharge process, the air and water vapor will generate thrust on the blades of the impeller ring, causing the impeller ring to rotate. The impeller ring will drive the hollow rod to rotate, and the hollow rod will in turn drive the stirring blades to rotate, stirring the humic acid inside the concentration tank. By using the injected air and water vapor to drive the stirring blades to rotate, the stirring is achieved without the need for an additional motor to drive the stirring, thus reducing production costs.
[0016] 2. After concentration is complete, rotate the impeller ring so that it is pressed tightly against the concentration tank by the spring force (the impeller ring's support feet are inserted into the receiving groove on the concentration tank). At this time, the impeller ring will seal the opening at the top of the base through the sealing gasket. The pressurization pump starts and injects air into the concentration tank through the air inlet pipe. As the air pressure above the liquid surface in the concentration tank increases, it will squeeze the humic liquid downwards, causing the humic liquid to enter the hollow rod through the opening at the bottom of the hollow rod, and then be discharged through the hollow rod and the drain pipe. Compared with traditional pump pumping, this method can avoid the humic liquid corroding the pump fluid. Attached Figure Description

[0024] This application provides a humic acid concentration device that effectively solves the technical problems of existing humic acid concentration devices. These devices require a motor-driven stirring rod for agitation, and after concentration, a pump is needed to extract the humic acid. This not only results in high manufacturing costs but also causes corrosion of the pump impeller due to the concentrated humic acid. In this new device, the filling cap is unscrewed to add the humic acid to the concentration tank. The bottom of the tank is then heated by a heating mechanism, causing the water in the humic acid to evaporate and concentrate. The impeller ring is supported by its bottom feet. A pressure pump is activated, injecting air into the concentration tank through the inlet pipe. The injected air mixes with water vapor and exits along the arc surface of the shroud from the opening at the top of the base. During this exit process, the air and water vapor exert thrust on the impeller ring blades. The impeller ring rotates, which in turn drives the hollow rod to rotate. The hollow rod, in turn, drives the stirring blades to rotate, stirring the humic acid inside the concentration tank. By using injected air and water vapor to drive the stirring blades, no additional motor is needed, thus reducing production costs. After concentration, the impeller ring is rotated so that it is pressed tightly against the concentration tank by the spring force (the impeller ring's support feet are inserted into the receiving groove on the concentration tank). At this time, the impeller ring will seal the opening at the top of the base through the sealing gasket. The pressure pump starts and injects air into the concentration tank through the air inlet pipe. As the air pressure above the liquid surface in the concentration tank increases, it will squeeze the humic liquid downwards, causing it to enter the hollow rod through the opening at the bottom of the hollow rod, and then be discharged through the hollow rod and the drain pipe. Compared with traditional pump pumping, this method avoids the humic liquid corroding the pump fluid.
[0025] Example
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing humic acid concentration equipment requires stirring by a motor-driven stirring rod during use, and after concentration, it is necessary to use equipment such as a liquid pump to extract the humic acid. This not only results in high manufacturing costs, but also causes corrosion of the impeller of the liquid pump by the concentrated humic acid. The overall idea is as follows:
[0027] To address the problems existing in the prior art, this utility model provides a humic acid concentration device, including a base 1, a concentration tank 2 fixedly installed on the base 1, a rectifier 3 fixedly installed on the concentration tank 2, and a hollow rod 4 for draining liquid rotatably installed on the rectifier 3.
[0028] A stirring blade 5 is fixedly installed on the hollow rod 4, an impeller ring 6 is fixedly installed on the hollow rod 4, a drain pipe 7 is fixedly installed on the concentration tank 2, the drain pipe 7 and the hollow rod 4 are rotatably connected by a labyrinth seal method, a pressure pump 8 is fixedly installed on the base 1, and a filling cap 9 is threaded on the concentration tank 2.
[0029] An air inlet pipe 11 is installed between the filling cap 9 and the pressurizing pump 8. The air inlet pipe 11 and the filling cap 9 are rotatably connected by a labyrinth seal. A sealing cap 12 is installed on the concentration tank 2. A spring 13 is installed at the top of the sealing cap 12 and a sealing gasket 14 is installed at the bottom of the sealing cap 12.
[0030] Base 1: It is the supporting foundation of the concentration equipment, providing an installation platform for components such as concentration tank 2 and pressurization pump 8, maintaining the overall stability of the equipment, and ensuring that the relative positions of each component remain unchanged during operation;
[0031] Concentration tank 2: Fixed to base 1, it is the key container for humic acid concentration. It holds the humic acid to be treated and concentrates it by heating the bottom with heating equipment to evaporate the water. At the same time, it provides installation sites for components such as rectifier 3, drain pipe 7, and sealing cover 12. After concentration, it works with other components to discharge the concentrated liquid.
[0032] 3. Fixing the shroud 2 changes the flow direction of air and water vapor, allowing the pressurizing pump 8 to inject air mixed with water vapor, which is discharged from the top opening of the base 1 along its arc surface, driving the impeller ring 6 to rotate and providing energy for stirring.
[0033] Hollow rod 4: Rotatably mounted on shroud 3, it serves as a connecting shaft for the stirring components, driving the stirring blades 5 to rotate and stir the humic acid in the concentration tank 2. After concentration, it serves as a discharge channel for the concentrated liquid, with the humic liquid entering from its bottom opening and being discharged from the equipment via a connection to the drain pipe 7.
[0034] Stirring blade 5: Fixed on hollow rod 4, it rotates with hollow rod 4 to stir the humic acid in concentration tank 2, promotes uniform heating of humic acid, accelerates water evaporation, and improves concentration efficiency.
[0035] Impeller ring 6: Fixed to the hollow rod 4, it rotates by the thrust generated by the exhaust of air and water vapor, which drives the hollow rod 4 and the stirring blade 5 to rotate, realizing stirring without the need for an additional motor, reducing costs. After concentration, it rotates to insert the support leg into the storage groove of the concentration tank 2, and under the elastic force of the spring 13, it is tightly attached to the concentration tank 2, and cooperates with the sealing gasket 14 to seal the top opening of the base 1 so that the concentrated liquid can be discharged by air pressure.
[0036] Drain pipe 7: Fixed to the concentration tank 2, and rotatably connected to the hollow rod 4 by a labyrinth seal method. After concentration is completed, it guides the humic liquid flowing out of the hollow rod 4 to the outside of the equipment.
[0037] Pressure pump 8: Fixed to base 1, it injects air into concentration tank 2 through air inlet pipe 11. During concentration, the injected air and water vapor drive impeller ring 6 to rotate. After concentration, the injected air increases the air pressure above the liquid surface in the tank and squeezes out the humic liquid.
[0038] Filler cap 9: Threaded onto the concentration tank 2, it is easy to open and add the humic acid to be treated. It also acts as a seal when the equipment is working to prevent liquid and gas leakage.
[0039] Air inlet pipe 11: Connects the filling cap 9 and the pressurizing pump 8, allowing the air injected by the pressurizing pump 8 to enter the concentrator 2. It is rotatably connected to the filling cap 9 through a labyrinth seal method (the labyrinth seal method is a technology that achieves fluid sealing through a non-contact tortuous channel structure. The core principle is to use the throttling effect and energy dissipation of the fluid in a complex path to complete the sealing between the rotating connecting parts), ensuring that the connection is sealed when air is injected and preventing gas leakage;
[0040] Sealing cover 12: Installed in the concentration tank 2, it works in conjunction with impeller ring 6, spring 13, sealing gasket 14 and other components to seal the concentration tank 2 after concentration, so that the pressure pump 8 can inject air to generate air pressure to discharge the humic liquid.
[0041] Spring 13: Installed on the top of the sealing cover 12, it provides elasticity to the impeller ring 6 after concentration, so that it fits tightly against the concentration tank 2, ensuring the sealing effect and allowing the air pressure to effectively squeeze the humic liquid out.
[0042] Sealing gasket 14: Installed at the bottom of sealing cover 12, it enhances the sealing performance at the contact point between impeller ring 6 and concentration tank 2, prevents leakage when pressurizing and discharging humic liquid, and ensures that the concentrate is smoothly discharged through hollow rod 4 and drain pipe 7.
[0043] Working principle:
[0044] The first step is to unscrew the filling cap 9 during use, and then add the humic acid to be treated into the concentration tank 2. Then, the bottom of the concentration tank 2 is heated by the heating mechanism, so that the water in the humic acid evaporates and is concentrated. At this time, the impeller ring 6 is supported by its own bottom feet. The pressure pump 8 is started and air is injected into the concentration tank 2 through the air inlet pipe 11. The injected air will mix with water vapor and be discharged from the opening at the top of the base 1 along the arc surface of the rectifier 3. During the discharge process, the air and water vapor will generate thrust on the blades of the impeller ring 6, causing the impeller ring 6 to rotate. The impeller ring 6 will drive the hollow rod 4 to rotate, and the hollow rod 4 will in turn drive the stirring blades 5 to rotate and stir the humic acid inside the concentration tank 2. By using the injected air and water vapor to drive the stirring blades 5 to rotate for stirring, there is no need to install an additional motor to drive the stirring, which achieves the effect of reducing production costs.
[0045] The second step involves rotating the impeller ring 6 after concentration is complete, causing it to press tightly against the concentration tank 2 under the force of the spring 13 (the support of the impeller ring 6 is inserted into the receiving groove on the concentration tank 2). At this time, the impeller ring 6 will seal the opening at the top of the base 1 through the sealing gasket 14. The pressurizing pump 8 is started and air is injected into the concentration tank 2 through the air inlet pipe 11. As the air pressure above the liquid surface in the concentration tank 2 increases, it will squeeze the humic liquid downwards, causing the humic liquid to enter the hollow rod 4 through the opening at the bottom of the hollow rod 4, and then be discharged through the hollow rod 4 and the drain pipe 7. Compared with traditional pump pumping, this method can avoid the humic liquid corroding the pump fluid.
[0046] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
