Description

Technical Field

[0001] This invention relates to the field of evaporator technology, specifically to an intelligent circulating evaporator and method for potassium formate production. Background Technology

[0002] Circulating evaporators are a type of evaporation equipment widely used in industries such as chemical, pharmaceutical, food, and environmental protection. Their core feature is that the material is forced to circulate or naturally circulates within the evaporator to achieve efficient heat transfer and concentration. After being heated in the heating chamber, the material partially vaporizes to form a vapor-liquid mixture. Due to density differences (natural circulation) or external force (forced circulation), the mixture flows into the separation chamber for vapor-liquid separation. Most of the concentrated solution returns to the heating chamber for the next cycle of heating until the predetermined concentration is reached, at which point it is discharged. The generated secondary steam then enters the condenser for condensation.

[0003] Publication No. CN105771290A discloses a circulating evaporator, including a heat exchanger, a vacuum crystallizer, a condenser, a liquid seal tank, a discharge pump, a circulating pump, and a circulating pipeline. One end of the heat exchanger is connected to the vacuum crystallizer via a pipeline, and the vacuum crystallizer is connected to the circulating pump via the circulating pipeline. The other end of the heat exchanger is connected to the circulating pipeline. The vacuum crystallizer is connected to the discharge pump via a pipeline, and the vacuum crystallizer is connected to the condenser via a pipeline. The condenser is connected to the liquid seal tank via a pipeline. The circulating evaporator described in the above application is equipped with a liquid seal tank, which recovers condensate, improving economic efficiency.

[0004] Although the aforementioned applications and prior art can recover condensate and thus improve economic efficiency, when the aforementioned applications and prior art circulate and evaporate potassium formate stock solution, a large amount of foam is generated during evaporation. This foam is easily carried into the condensation system by secondary steam, resulting in "material leakage". Furthermore, when the foam is broken up by rotating the plate, the centrifugal force generated by the plate rotation causes small foam to disperse inside the evaporator, affecting subsequent condensation. Moreover, when the foam is broken up, mist is generated, and a large amount of mist enters the subsequent condensation system with the steam, leading to condensation system failure. Therefore, this invention proposes an intelligent circulating evaporator and method for potassium formate production. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an intelligent circulating evaporator and method for potassium formate production. It offers advantages such as preventing foaming, avoiding dispersion, and preventing mist. This solves the problems of the aforementioned applications and existing technologies, where the potassium formate stock solution generates a large amount of foam during evaporation. This foam is easily carried into the condensation system by secondary steam, causing "material leakage." Furthermore, when the foam is broken up by rotating plates, the centrifugal force generated by the plate rotation causes small bubbles to disperse inside the evaporator, affecting subsequent condensation. Additionally, the breaking up of the foam generates mist, and a large amount of mist enters the subsequent condensation system with the steam, leading to condensation system malfunctions.

[0008] To achieve the aforementioned objectives of preventing foaming, avoiding dispersion, and preventing mist, this invention provides the following technical solution: an intelligent circulating evaporator for potassium formate production, comprising: an evaporator tank and a processing tank disposed on one side of the evaporator tank, and further comprising:

[0009] A steam pipe is fixedly connected to the surface of the evaporator. The evaporator and the processing tank are connected through a steam outlet pipe. A cooking box is fixedly connected inside the evaporator, and a liquid inlet pipe is fixedly connected to the surface of the cooking box.

[0010] A defoaming assembly is installed inside the evaporator to remove the foam generated during the evaporation of the original liquid, so as to prevent the foam from affecting the evaporation of the original liquid. The defoaming assembly includes a drive rod rotatably connected inside the evaporator. An extension rod is slidably connected inside the drive rod through a keyway. A scraper is fixedly connected to the surface of the extension rod.

[0011] An anti-drift component is installed inside the evaporator to break up the foam that drifts inside the evaporator and prevent the foam from entering subsequent processing procedures.

[0012] An anti-foaming component is installed inside the evaporator to prevent the mist generated after the foam breaks from entering subsequent processing procedures, thereby affecting the evaporation quality.

[0013] Furthermore, the defoaming assembly also includes a drive motor fixedly connected to the top of the evaporator, the output end of the drive motor being fixedly connected to the top end of the drive rod, and a floating plate being fixedly connected to the bottom of the extension rod.

[0014] Furthermore, the anti-drift assembly includes a support plate fixedly connected inside the evaporator. The bottom of the support plate is rotatably connected to a rotating rod via a support plate. The rotating rod and the drive rod are transmitted through a transmission mechanism.

[0015] Furthermore, a rotating disk is fixedly connected to one end of the rotating rod, a fixed rod is fixedly connected to one end of the rotating disk, a frame is provided on the surface of the fixed rod, and a tension rod is fixedly connected to the bottom of the frame.

[0016] Furthermore, the anti-drift assembly also includes a squeezing disc slidably connected inside the evaporator. The bottom of the squeezing disc has several openings, and the top of the squeezing disc is fixedly connected to a collecting cone disc. The top of the collecting cone disc is fixedly connected to the bottom of the tension rod.

[0017] Furthermore, the anti-fog assembly includes a push rod fixedly connected to the top of the frame and an air supply cylinder fixedly connected to the bottom of the support plate. A push plate is fixedly connected to the top of the push rod, and the push plate is slidably connected inside the air supply cylinder.

[0018] Furthermore, the anti-fogging assembly also includes an air storage cylinder fixedly connected to the bottom of the support plate and a conical cylinder fixedly connected inside the evaporator. The air storage cylinder and the air delivery cylinder are connected through an air delivery pipe. A first one-way valve is provided on the surface of the air delivery pipe. The air storage cylinder and the conical cylinder are connected through an exhaust pipe. A throttling valve is provided on the surface of the exhaust pipe. The conical cylinder and the collecting cone are connected through an inlet pipe.

[0019] Furthermore, the anti-fogging component also includes a water return trough located on the top of the extrusion plate. The bottom of the water return trough is fixedly connected to a water return pipe. A support rod is fixedly connected inside the water return pipe. A floating ball is slidably connected to the surface of the support rod. A blocking block is fixedly connected to the top of the support rod.

[0020] Furthermore, the surface of the steam pipe is provided with an air inlet valve, the surface of the liquid inlet pipe is provided with a water inlet valve, the top of the treatment tank is fixedly connected to an exhaust pipe, and one end of the exhaust pipe is fixedly connected to the surface of the conical cylinder.

[0021] This invention also provides a smart circulating evaporation method for potassium formate production, which specifically includes the following steps:

[0023] Step 2: When foam appears inside the cooking box, the defoaming assembly rotates the defoaming plate to break up the foam.

[0024] Step 3: When the centrifugal force generated by the rotating scavenger causes small bubbles to disperse in the evaporator, the defoaming component will simultaneously drive the anti-drift component to break up the small bubbles, thereby preventing them from entering the treatment tank.

[0025] Step 4: When the foam is broken and mist is generated, the anti-foaming component is activated simultaneously, causing the anti-foaming component to blow out airflow to collect the mist, so that the mist forms water droplets that will stay inside the cooking box.

[0026] Step 5: The steam generated during the evaporation of the original liquid inside the cooking box is transported to the interior of the processing tank through the steam outlet pipe, so that the steam can be used later.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the present invention provides an intelligent circulating evaporator and method for potassium formate production, which has the following beneficial effects:

[0029] 1. The intelligent circulating evaporator and method for potassium formate production utilizes a defoaming component. The drive motor is activated, and through a drive rod, it rotates an extension rod, which in turn rotates several defoaming blades. The rapid rotation of these blades strikes the foam, breaking it up inside the cooking chamber and thus preventing foam formation.

[0030] 2. This intelligent circulating evaporator and method for potassium formate production utilizes a combination of a defoaming component and an anti-drift component. When the drive rod rotates the extension rod, the drive rod drives the rotating rod to rotate via a transmission mechanism. This rotating rod then drives the fixed rod to rotate via a rotating disc. As the fixed rod rotates, it drives the tension rod to reciprocate via a frame. This causes the tension rod to drive the extrusion disc to move up and down via a collecting cone disc. Through the continuous up and down movement of the extrusion disc, the extrusion disc breaks up the drifting small foam, preventing the foam from drifting inside the evaporator and thus achieving the effect of preventing drift.

[0031] 3. This intelligent circulating evaporator and method for potassium formate production utilizes an anti-drift component and an anti-fogging component. When the frame moves back and forth along the tension rod, the frame moves back and forth along the push rod along the push plate inside the gas delivery cylinder. This allows air inside the gas delivery cylinder to be continuously delivered to the gas storage cylinder through the gas delivery pipe. Due to the presence of the throttle valve, air inside the gas storage cylinder is continuously delivered to the conical cylinder through the exhaust pipe. This causes the air to rotate at high speed along the inner wall of the conical cylinder. Simultaneously, due to the continuous movement of the extrusion plate, steam containing mist enters the collecting conical plate through the opening, and then enters the conical cylinder through the mist inlet pipe. The high-speed rotating air separates the mist from the steam containing mist, causing the mist to gradually accumulate on the inner wall of the conical cylinder and eventually fall off, thus achieving the effect of preventing mist.

[0032] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0052] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 3 A smart circulating evaporator for potassium formate production includes: an evaporator 1 and a processing tank 131 disposed on one side of the evaporator 1, and further includes:

[0053] A steam pipe 11 is fixedly connected to the surface of the evaporator 1. The evaporator 1 and the processing tank 131 are connected through the steam outlet pipe 13. A cooking box 12 is fixedly connected inside the evaporator 1. A liquid inlet pipe 121 is fixedly connected to the surface of the cooking box 12. An air inlet valve 111 is provided on the surface of the steam pipe 11. A water inlet valve is provided on the surface of the liquid inlet pipe 121. An exhaust pipe 132 is fixedly connected to the top of the processing tank 131.

[0054] The defoaming assembly 2 is installed inside the evaporator 1 to remove the foam generated during the evaporation of the original liquid, so as to prevent the foam from affecting the evaporation of the original liquid. The defoaming assembly 2 includes a drive rod 211 rotatably connected inside the evaporator 1. An extension rod 22 is slidably connected inside the drive rod 211 through a keyway. A scraper 222 is fixedly connected to the surface of the extension rod 22.

[0055] The anti-drift component 3 is installed inside the evaporator 1 to break up the foam that drifts inside the evaporator 1 and prevent the foam from entering the subsequent processing procedures.

[0056] The anti-foaming component 4 is installed inside the evaporator 1 to prevent the mist generated after the foam breaks from entering the subsequent processing procedures, thereby affecting the evaporation quality;

[0057] It should be noted that the bottom of the cooking box 12 is fixedly connected to a discharge pipe, and a discharge valve is provided on the surface of the discharge pipe.

[0058] When it is necessary to evaporate the potassium formate stock solution, the potassium formate stock solution is poured into the cooking box 12 through the liquid inlet pipe 121, then the liquid inlet pipe 121 is closed, and then the air inlet valve 111 is opened to allow steam to enter the evaporation tank 1 through the steam pipe 11, thereby allowing the steam to evaporate the potassium formate stock solution in the cooking box 12. The steam generated during the evaporation of the potassium formate stock solution enters the processing tank 131 through the air outlet pipe 13, so that the processing tank 131 can process the steam.

[0059] For a specific embodiment two, please refer to Figures 1 to 6 Based on the intelligent circulating evaporator for potassium formate production provided in Specific Embodiment 1, this embodiment provides a further technical solution:

[0060] The defoaming assembly 2 also includes a drive motor 21 fixedly connected to the top of the evaporator 1. The output end of the drive motor 21 is fixedly connected to the top end of the drive rod 211, and a float plate 221 is fixedly connected to the bottom of the extension rod 22.

[0061] When it is necessary to treat the foam generated during the evaporation of potassium formate stock solution inside the cooking box 12, after the potassium formate stock solution is poured into the cooking box 12, the potassium formate stock solution is gradually collected inside the drive rod 211 by the extension rod 22 driven by the float plate 221, so that the bottom of the skimmer 222 contacts the top of the potassium formate stock solution. Then the drive motor 21 is started, and the drive motor 21 drives the extension rod 22 to rotate through the drive rod 211, so that the extension rod 22 drives several skimmers 222 to rotate. Through the rapid rotation of the skimmers 222, the skimmers 222 strike the foam, thereby breaking the foam inside the cooking box 12 and preventing the foam from entering the treatment tank 131 through the vent pipe 13.

[0062] For a specific embodiment three, please refer to Figures 1 to 11 Based on the intelligent circulating evaporator for potassium formate production provided in Specific Embodiment 2, this embodiment provides a further technical solution:

[0063] The anti-drift assembly 3 includes a support plate 31 fixedly connected inside the evaporator 1. The bottom of the support plate 31 is rotatably connected to a rotating rod 311 via a support plate. The rotating rod 311 and the drive rod 211 are transmitted through a transmission mechanism 34. One end of the rotating rod 311 is fixedly connected to a rotating disk 312. One end of the rotating disk 312 is fixedly connected to a fixing rod 313. A frame 32 is provided on the surface of the fixing rod 313. A tension rod 321 is fixedly connected to the bottom of the frame 32. The anti-drift assembly 3 also includes a squeezing disk 33 slidably connected inside the evaporator 1. The bottom of the squeezing disk 33 has several openings 331. A collecting cone disk 332 is fixedly connected to the top of the squeezing disk 33. The top of the collecting cone disk 332 is fixedly connected to the bottom of the tension rod 321.

[0064] It should be noted that the transmission mechanism 34 includes a driving bevel gear fixedly connected to the surface of the drive rod 211 and a driven bevel gear fixedly connected to the surface of the rotating rod 311. The driving bevel gear and the driven bevel gear mesh and transmit power.

[0065] When it is necessary to prevent the centrifugal force generated by the rotation of the scraper 222 from causing small foams to disperse in the evaporator 1, when the drive rod 211 drives the extension rod 22 to rotate, the drive rod 211 drives the rotating rod 311 to rotate through the transmission mechanism 34, so that the rotating rod 311 drives the fixed rod 313 to rotate through the rotating disk 312. When the fixed rod 313 rotates, it drives the tension rod 321 to move back and forth through the frame 32, so that the tension rod 321 drives the extrusion disk 33 to move up and down through the collecting cone disk 332. Through the continuous up and down movement of the extrusion disk 33, the extrusion disk 33 breaks up the dispersed small foams, so that the foams no longer disperse inside the evaporator 1, thereby preventing small foams from entering the processing tank 131 through the gas outlet pipe 13.

[0066] For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 15 Based on the intelligent circulating evaporator for potassium formate production provided in Specific Embodiment 3, this embodiment provides a further technical solution:

[0067] The anti-fogging component 4 includes a push rod 41 fixedly connected to the top of the frame 32 and an air supply cylinder 42 fixedly connected to the bottom of the support plate 31. A push plate 411 is fixedly connected to the top of the push rod 41 and the push plate 411 is slidably connected inside the air supply cylinder 42. The anti-fogging component 4 also includes an air storage cylinder 422 fixedly connected to the bottom of the support plate 31 and a conical cylinder 43 fixedly connected inside the evaporator 1. The air storage cylinder 422 and the air supply cylinder 42 are connected through an air supply pipe 421. A first one-way valve 423 is provided on the surface of the air supply pipe 421. The air storage cylinder 422 and the conical cylinder 43 are connected through an exhaust pipe 424. A throttling valve 425 is provided on the surface of the exhaust pipe 424. The conical cylinder 43 and the collecting cone plate 332 are connected through an inlet pipe 431. One end of the outlet pipe 13 is fixedly connected to the surface of the conical cylinder 43.

[0068] It should be noted that a second one-way valve is provided on the surface of the push plate 411. When the push plate 411 moves toward the top of the air cylinder 42, the second one-way valve closes, and vice versa.

[0069] When it is necessary to treat the mist generated when the foam breaks, when the frame 32 drives the tension rod 321 to move back and forth, the frame 32 drives the push plate 411 to move back and forth inside the air supply cylinder 42 through the push rod 41, so that the air inside the air supply cylinder 42 is continuously transported to the inside of the air storage cylinder 422 through the air supply pipe 421. Due to the presence of the throttle valve 425, the air inside the air storage cylinder 422 is continuously transported to the inside of the conical cylinder 43 through the exhaust pipe 424, so that the air rotates at high speed along the inner wall of the conical cylinder 43. At the same time, due to the continuous up and down movement of the extrusion plate 33, the steam containing mist enters the inside of the collecting conical plate 332 through the opening 331, and then enters the inside of the conical cylinder 43 through the mist inlet pipe 431. Then, the steam containing mist separates the mist through the high-speed rotating air, so that the mist gradually gathers on the inner wall of the conical cylinder 43 to form water droplets. The treated steam enters the inside of the treatment tank 131 through the exhaust pipe 13.

[0070] For a specific implementation example, please refer to Implementation Example 5. Figures 1 to 16 Based on the intelligent circulating evaporator for potassium formate production provided in Specific Embodiment 4, this embodiment provides a further technical solution:

[0071] The anti-fogging component 4 also includes a water return tank 44 opened on the top of the extrusion plate 33. The bottom of the water return tank 44 is fixedly connected to a water return pipe 441. A support rod 442 is fixedly connected inside the water return pipe 441. A floating ball 443 is slidably connected to the surface of the support rod 442. A blocking block 444 is fixedly connected to the top of the support rod 442.

[0072] When it is necessary to return the water droplets gathered on the inner wall of the conical cylinder 43 to the cooking box 12, as the mist gradually gathers on the inner wall of the conical cylinder 43 to form water droplets, the water droplets drip down the inner wall of the conical cylinder 43 into the return water tank 44 at the top of the extrusion plate 33. As the water droplets continuously gather in the return water tank 44, the water droplets form a liquid surface, causing the floating ball 443 to slide on the surface of the support rod 442, thereby preventing the floating ball 443 from blocking the return water pipe 441, and allowing the water droplets to fall into the cooking box 12 through the return water pipe 441.

[0073] In a specific embodiment six, the present invention also provides an intelligent circulating evaporation method for potassium formate production, which specifically includes the following steps:

[0074] Step 1: Pour the raw liquid into the cooking box 12 through the liquid inlet pipe 121, and then send steam into the evaporator 1 through the steam pipe 11 so that the steam evaporates the raw liquid in the cooking box 12.

[0075] Step 2: When foam appears inside the cooking box 12, the defoaming assembly 2 rotates the defoaming plate 222 to break up the foam.

[0076] Step 3: When the centrifugal force generated by the rotating shaving plate 222 causes small bubbles to disperse in the evaporator 1, the defoaming component 2 simultaneously drives the anti-drift component 3 to break up the small bubbles, thereby preventing the small bubbles from entering the treatment tank 131.

[0077] Step 4: When the foam is broken and mist is generated, the anti-foaming component 3 operates simultaneously and drives the anti-foaming component 4, so that the anti-foaming component 4 blows out airflow to collect the mist, so that the mist forms water droplets that will stay inside the cooking box 12.

[0078] Step 5: The steam generated during the evaporation of the original liquid inside the cooking box 12 is transported to the interior of the processing tank 131 through the steam outlet pipe 13, so that the steam can be used conveniently in subsequent processes.

[0079] Working principle: In use, potassium formate stock solution is poured into the cooking box 12 through the inlet pipe 121, then the inlet pipe 121 is closed, and the air inlet valve 111 is opened to allow steam to enter the evaporator 1 through the steam pipe 11, thereby evaporating the potassium formate stock solution in the cooking box 12. The steam generated during the evaporation of potassium formate stock solution enters the processing tank 131 through the air outlet pipe 13, allowing the processing tank 131 to process the steam. When it is necessary to treat the foam generated during the evaporation of potassium formate stock solution inside the cooking box 12, after the potassium formate stock solution is poured into the cooking box 12, the potassium formate stock solution is gradually retracted into the drive rod 211 by the extension rod 22 driven by the float plate 221, thereby making the bottom of the skimmer 222 contact the potassium formate. The top of the original liquid comes into contact with the liquid, and then the drive motor 21 is started. The drive motor 21 drives the extension rod 22 to rotate via the drive rod 211, which in turn drives several skimmers 222 to rotate. The rapid rotation of the skimmers 222 causes them to strike the foam, thereby breaking up the foam inside the cooking box 12 and preventing it from entering the processing tank 131 through the vent pipe 13. To prevent the centrifugal force generated by the rotation of the skimmers 222 from causing small foams to disperse in the evaporator 1, when the drive rod 211 drives the extension rod 22 to rotate, the drive rod 211 drives the rotating rod 311 to rotate via the transmission mechanism 34. The rotating rod 311 then drives the fixed rod 313 to rotate via the rotating disk 312. During rotation, the frame 32 drives the tension rod 321 to reciprocate, causing the tension rod 321 to drive the extrusion plate 33 to move up and down via the collecting cone plate 332. The continuous up-and-down movement of the extrusion plate 33 breaks up the scattered small bubbles, preventing them from dispersing inside the evaporator 1 and thus preventing them from entering the processing tank 131 through the outlet pipe 13. When it is necessary to treat the mist generated during foam breaking, as the frame 32 drives the tension rod 321 to reciprocate, the frame 32, via the push rod 41, drives the push plate 411 to reciprocate inside the gas delivery cylinder 42. This allows air inside the gas delivery cylinder 42 to be continuously delivered to the gas storage cylinder 422 through the gas delivery pipe 421. Due to the presence of the throttle valve 425, Air from inside the gas storage cylinder 422 is continuously supplied to the interior of the conical cylinder 43 through the exhaust pipe 424, causing the air to rotate at high speed along the inner wall of the conical cylinder 43. Simultaneously, due to the continuous up-and-down movement of the extrusion disc 33, steam containing mist enters the interior of the collecting conical disc 332 through the opening 331, and then enters the interior of the conical cylinder 43 through the mist inlet pipe 431. The high-speed rotating air separates the mist from the steam, causing it to gradually collect on the inner wall of the conical cylinder 43, forming water droplets. The treated steam then enters the interior of the processing tank 131 through the exhaust pipe 13. When it is necessary to return the water droplets collected on the inner wall of the conical cylinder 43 to the cooking box 12, as the mist gradually collects on the inner wall of the conical cylinder 43,...Water droplets drip down the inner wall of the conical cylinder 43 into the return water tank 44 at the top of the extrusion plate 33. As the droplets accumulate in the return water tank 44, they form a liquid surface that causes the floating ball 443 to slide on the surface of the support rod 442. This prevents the floating ball 443 from clogging the return water pipe 441, allowing the water droplets to fall into the cooking box 12 through the return water pipe 441.

It also allows for errors within a small angular range, such as within 10 degrees of assembly error. These can all be considered as parallel relationships.

[0083] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0084] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
