Description

Technical Field

[0001] The invention relates to the field of calcium lactate production, in particular to a forced circulation evaporation device based on the production of calcium lactate. Background Art

[0002] In the production process of calcium lactate, the evaporation device is used to concentrate the calcium lactate solution and remove the solvent (usually water) to increase the concentration of calcium lactate or promote crystallization. The core purpose is to obtain concentrated calcium lactate solution or calcium lactate crystals by heating or reducing the pressure and evaporating water.

[0003] However, during the evaporation process, inorganic salts and impurities in the solution may be deposited on the surface of the evaporator to form scaling, affecting the continuation of the evaporation process. In addition, the solute concentration in the solution gradually increases. If the solubility reaches saturation or supersaturation, crystallization will begin to precipitate. Calcium lactate may be deposited at the bottom of the evaporator, causing blockage in the discharge pipe and affecting the normal discharge of the discharge pipe. In other words, adaptive adjustment cannot be performed when abnormal discharge occurs. For this reason, a solution is now proposed. Summary of the Invention

DETAILED DESCRIPTION

[0017] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1 - Figure 6 As shown, this embodiment is a forced circulation evaporation device based on the production of calcium lactate, including a tank body 1, a partition plate 11 is fixedly installed inside the tank body 1, and the interior of the tank body 1 is divided into cavity 12 and cavity 2 13 by the partition plate 11. The partition plate 11 is located at the center of the tank body 1, and a rotating rod 14 is movably installed at the center of the partition plate 11, and a scraper 15 is fixedly installed on the rotating rod 14.

[0019] Through the linkage design of the scraper 15 and the rotating rod 14, the scraper 15 is tilted to fit the inner wall of the partition plate 11, so that crystals or residues on the heating surface are removed in real time to avoid the decrease in heat transfer efficiency caused by scaling. At the same time, the circulation pump 32 is used to transport the liquid at the bottom of the tank body 1 to the guide plate 33, and the guide plate 33 guides the liquid to flow toward the partition plate 11 and form a liquid film on the inner wall of the partition plate 11, thereby further improving the evaporation efficiency. That is, the circulation pump 32 is used to form a forced circulation path to accelerate material mixing and heat exchange.

[0020] The tank body 1 is divided into cavity 12 and cavity 2 13 by the partition plate 11, wherein cavity 12 serves as the evaporation area and cavity 2 13 serves as the circulation area. That is, combined with the liquid flow channel design, the physical separation of evaporation and circulation is achieved, the secondary steam interference is reduced, and the evaporation efficiency is improved.

[0021] A circulating evaporation assembly 3 is fixedly installed inside the tank body 1. The circulating evaporation assembly 3 includes a rotating rod 31, a circulating pump 32 and a guide plate 33. The guide plate 33 is fixedly installed in the tank body 1. The guide plate 33 is located above the partition plate 11. The guide plate 33 is annular and has a through groove at the center for liquid to pass through.

[0022] The guide plate 33 is tilted downward, and the direction is tilted from the inner wall of the tank body 1 to the partition plate 11. There is a clearance fit between the guide plate 33 and the partition plate 11. A heating jacket is provided inside the partition plate 11. An air supply pipe 39 is fixedly installed on the top of the tank body 1. One end of the air supply pipe 39 is fixedly connected to the heating jacket. An exhaust pipe 40 is fixedly installed on the top of the partition plate 11. It should be noted that an electric heating plate is fixedly installed at the bottom of the tank body 1, and the liquid inside the tank body 1 is continuously heated by the electric heating plate. As the temperature of the liquid rises, high-temperature steam is generated and moves upward. The high-temperature steam is transported to the heating jacket via the gas pipe 39 to heat the partition plate 11. The steam flows in the heating jacket to the exhaust pipe 40 for discharge.

[0023] That is, the steam generated when the liquid is heated is reused, which effectively reduces energy consumption. At the same time, when the circulation pump 32 sprays the liquid at the bottom of the tank body 1 to the top of the tank body 1, the liquid first contacts the guide plate 33. On the one hand, it avoids uneven heating of the liquid. On the other hand, under the action of the guide plate 33, the liquid flows into the partition plate 11 from the gap between the guide plate 33 and the partition plate 11, thereby controlling the flow state of the liquid, forming a liquid film on the inner wall of the partition plate 11, and improving the heat transfer efficiency.

[0024] A liquid inlet pipe and a motor are fixedly installed on the top of the tank body 1. The motor is located at the center of the top of the tank body 1. The output end of the motor is fixedly connected to the rotating rod 14. A cross bar 41 is fixedly installed on the rotating rod 14. One end of the cross bar 41 is fixedly connected to the scraper 15. The scraper 15 is set at an angle, and one side of the scraper 15 is in contact with the inner wall of the partition plate 11.

[0025] The circulation pump 32 is fixedly installed at the bottom of the tank body 1, and the rotating rod 2 31 is movably installed between the partition plate 11 and the tank body 1. The rotating rod 2 31 is located above the circulation pump 32. A discharge pipe 16 is fixedly installed at the bottom of the tank body 1. After the liquid is evaporated, the concentrated liquid is transported to the crystallization area for crystallization through the discharge pipe 16.

[0026] The circulating evaporation component 3 also includes a screw rod 34, a moving block 35, an airbag 1 36 and an airbag 2 37. One end of the screw rod 34 is fixedly connected to the rotating rod 2 31, the moving block 35 is movably mounted on the screw rod 34, the airbag 1 36 is fixedly mounted on one side of the moving block 35, the airbag 2 37 is fixedly mounted in the discharge pipe 16, and an extrusion block is fixedly mounted on the airbag 2 37. The airbag 1 36 is fixedly connected to the airbag 2 37 through a pipeline.

[0027] A liquid flow channel is opened at the center of the partition plate 11. The cross-section of the partition plate 11 is a cone with a larger upper part and a smaller lower part. A connecting rod is fixedly installed on the partition plate 11. One end of the connecting rod is fixedly connected to the inner wall of the tank body 1. There are multiple connecting rods, and the multiple connecting rods are evenly spaced on the partition plate 11.

[0028] A plurality of driving blocks 38 are fixedly mounted on the rotating rod 2 31 . The rotating rod 2 31 is provided with a plurality of driving blocks 38 , which are evenly spaced inside the tank body 1 . The driving block 38 is semicircular and has a cavity. The driving block 38 is located directly above the circulating pump 32 . When the circulating pump 32 is working, the high-speed water flow directly collides with the cavity, and then utilizes the impact force of the high-speed liquid to drive the rotating rod 2 31 to rotate.

[0029] A connecting plate is fixedly installed on the outer wall of the tank body 1, and a screw rod 34 is movably installed in the connecting plate. A movable nut 42 is movably installed on the screw rod 34 through a thread. The movable block 35 is fixedly installed on one side of the movable nut 42, and the two ends of the airbag 36 are fixedly connected to the movable block 35 and the connecting plate respectively.

[0030] That is, when the rotating rod 2 31 rotates, it drives the screw rod 34 to rotate synchronously, and under the action of the thread, drives the movable nut 42 to move. It should be noted that a reciprocating thread is provided on the surface of the screw rod 34 in this embodiment, that is, as the screw rod 34 continues to rotate, the movable nut 42 performs reciprocating motion on the screw rod 34, and then uses the movable plate to drive the airbag 1 36 to expand and contract. When the airbag 1 36 contracts, the gas enters the airbag 2 37, thereby driving the extrusion block to squeeze the liquid in the discharge pipe 16, thereby preventing the crystal from clogging the discharge pipe 16.

[0031] That is, through the linkage of airbag 1 36 and airbag 2 37 , the pressure of the discharge pipe 16 can be dynamically adjusted to prevent blockage and control the discharge flow rate, thereby effectively improving the discharge efficiency of the discharge pipe 16 .

[0032] Example 2: Please refer to Figure 7 As shown, the present invention further includes a control panel 2, the outer wall of the tank body 1 is fixedly mounted with the control panel 2, and the control panel 2 includes a server, a discharge monitoring module and a remote monitoring terminal; The discharge monitoring module is used to monitor the conveying environment of the discharge pipe 16, generate a normal discharge signal or an abnormal discharge signal through process analysis, and send the abnormal discharge signal to the remote monitoring end via the server; The specific operation process of the discharge monitoring module includes: The liquid flow rate data in the discharge pipe 16 is collected by a liquid flow meter fixedly installed in the discharge pipe 16. The liquid flow rate per unit time is averaged to obtain the flow mean. A coordinate system is constructed with time as the X-axis and the collected flow mean data as the Y-axis. The flow mean data per unit time is marked on the coordinate system, and a set threshold curve is plotted in the coordinate system. If the flow mean data fluctuates, it will appear to float downward on the coordinate system. For example, when there are too many crystals inside the concentrate, causing the discharge pipe 16 to be blocked, the liquid flow gradually decreases. At this time, the liquid flow per unit time changes, and the flow mean value curve fluctuates downward on the coordinate system. At this time, the area of ​​the floating waveform deviation region between the flow mean data curve and the threshold curve is calculated. The area of ​​the floating waveform deviation region per unit time is the deviation value.

[0033] If the deviation value exceeds the set threshold and continues to increase, it is inferred that there is an abnormality in the current discharge pipe 16, and a discharge abnormality signal is generated, and the discharge abnormality signal is sent to the remote monitoring end via the server.

[0034] It should be noted that the set thresholds are all threshold values ​​manually set by personnel in the evaporation device operation field based on historical operation abnormality scenarios. If the set threshold is not suitable for the current scenario, the threshold is updated to ensure accurate data detection in the current scenario.

[0035] When the remote monitoring terminal receives the abnormal discharge signal, it immediately controls the circulation pump 32 to work and issues a corresponding early warning.

[0036] Among them, the working principle of the circulation pump 32 is: When an abnormal discharge signal is received, the remote monitoring end controls the circulation pump 32 to increase its speed. At this time, the circulating liquid flow rate increases, which increases the liquid impact force, thereby increasing the speed of the rotating rod 2 31 and shortening the contraction-expansion cycle of the airbag 1 36, thereby driving the extrusion block to move at a higher frequency. On the one hand, the crystal is broken to relieve the discharge pressure of the discharge pipe 16. On the other hand, the pressure of the discharge pipe 16 is dynamically adjusted to prevent blockage and control the discharge flow rate, effectively improving the discharge efficiency of the discharge pipe 16.

[0037] That is, the characteristic data of the liquid in the discharge pipe 16 are collected and evaluated, and the influence of the collected data itself and the influence on the evaporation device are combined to improve the targeted control of the evaporation device. When an abnormality occurs, it can be quickly judged and processed based on the data collection results. It can also control the corresponding structure to perform compensatory operations based on the evaluation results, fundamentally reducing the impact of the abnormality, improving the operating efficiency of the evaporation device, and at the same time minimizing the failure rate of the evaporation device.

[0038] Combining Example 1 and Example 2, it can be seen that by collecting data during the use of the discharge pipe 16, a normal discharge signal or an abnormal discharge signal can be obtained, and the discharge situation of the evaporation device can be comprehensively and efficiently supervised during use, that is, the collected data range is comprehensively analyzed and compared with the preset data range, so as to obtain relevant evaluation signals, and accordingly send corresponding early warnings to the remote monitoring end to achieve precise adjustment and control of the discharge process, and for abnormal discharge, the inside of the discharge pipe 16 is regulated through the cooperation of airbag 1 36 and airbag 2 37, thereby fundamentally reducing the impact of abnormal discharge and effectively improving the utilization efficiency of the evaporation device.
