Description

Technical Field

[0001] The utility model relates to the field of concentrators, in particular to a high-efficiency and energy-saving evaporation concentrator. Background Art

[0002] Traditional Chinese medicine evaporation concentration is to remove excess water from the water extract of traditional Chinese medicine by heating or reducing pressure to achieve the purpose of concentrating the effective ingredients of the medicine. This process helps to improve the efficacy of traditional Chinese medicine. At the same time, the concentrated drug ingredients are more stable, which is conducive to long-term storage and transportation. In addition, the concentrated traditional Chinese medicine extracts are also more suitable for pharmacological research, which helps to deeply understand its mechanism of action and clinical application.

[0003] The process of evaporation and concentration of traditional Chinese medicine usually uses a special evaporation concentrator. The evaporation concentrator can replace the manual process of evaporation and concentration of traditional Chinese medicine, but it still has some problems: 1) The evaporation rate of traditional Chinese medicine evaporation concentrator is low, so the speed of the entire evaporation and concentration process is limited; 2) The steam condensation efficiency of traditional Chinese medicine evaporation concentrator is low, thereby delaying the concentration efficiency; Therefore, in view of the above situation, it is urgent to develop a high-efficiency and energy-saving evaporation concentrator to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the utility model is to provide a high-efficiency and energy-saving evaporation concentrator to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The high-efficiency and energy-saving evaporation concentrator comprises an evaporation kettle, a condensation kettle and a base, wherein the evaporation kettle is vertically installed on the top of the base, and the condensation kettle is vertically arranged on the top of the evaporation kettle and is connected and fixed to the evaporation kettle;

[0007] The evaporator also includes an impeller, a liquid supply pipe, a laminar flow plate, a top flow plate, a liquid inlet and outlet interface and a motor. The liquid supply pipe is vertically installed in the middle position of the inner bottom of the evaporator, the impeller is horizontally embedded and installed in the middle position of the inner bottom of the evaporator, and the discharge port of the impeller is connected with the bottom end of the liquid supply pipe. The top flow plate is horizontally installed at the top end of the liquid supply pipe, and the middle position of the top flow plate is connected and fixed with the top end of the liquid supply pipe. Several laminar flow plates are nested and installed in the middle section of the liquid supply pipe. The liquid inlet and outlet interfaces are obliquely installed at the bottom edge of the evaporator, and the motor is horizontally installed at the bottom edge of the evaporator. The outer diameters of the several laminar flow plates are not consistent. The outer diameter of the upper laminar flow plate is equal to the diameter of the groove of the next laminar flow plate. Therefore, the liquid medicine sliding down from the upper laminar flow plate can just fall into the groove of the next laminar flow plate.

[0008] The condensing kettle also includes an inner cylinder, an inner spiral partition, a condensing plate and a partition cover. The inner cylinder is embedded and installed inside the condensing kettle, the inner spiral partition is embedded and installed between the outer wall of the inner cylinder and the condensing kettle, and several condensing plates are installed obliquely on the inner wall of the inner cylinder. A steam interface is opened in the middle position of the bottom of the condensing kettle, and a vertically arranged partition cover is installed between the steam interface and the inner wall of the condensing kettle. A drain outlet is installed at the bottom edge of the condensing kettle, and the drain outlet is connected from the inside of the condensing kettle to the partition cover.

[0009] As a further solution of the utility model: the impeller is connected to the motor drive, and the motor drives the impeller to rotate. The liquid to be evaporated in the evaporator enters the interior through the liquid inlet of the impeller, and then the liquid is pumped into the liquid supply pipe through the impeller, and the liquid slowly flows out from the top of the liquid supply pipe.

[0010] As a further solution of the utility model: the edge of the top flow plate is arc-shaped toward the bottom, and the liquid medicine slowly slides downward through the arc-shaped edge of the top flow plate and falls into the groove of the laminar flow plate below.

[0011] As a further solution of the utility model: a groove is provided in the middle position of the laminar plate, an outer edge of the laminar plate is provided with an outer arc inclined toward the bottom, an inner edge of the laminar plate is provided with an inner arc inclined toward the bottom, and a bracket for connecting with a liquid supply pipe is welded in the middle position of the laminar plate. The liquid that slides down from the outer arc of the previous laminar plate is collected through the provided groove, and the collected liquid is discharged downward through its own outer arc and inner arc, thereby expanding the contact area between the liquid and the air and promoting the evaporation process.

[0012] As a further solution of the utility model: an inner flow channel is formed between the inner cylinder and the inner spiral partition, and the inner flow channel can form an inner and outer temperature difference of the inner cylinder of the evaporator, thereby improving the condensation efficiency.

[0013] As a further solution of the utility model: a water supply port and a reflux port are also installed on the side of the condensing kettle, and the water supply port and the reflux port are respectively connected to the two ends of the inner flow channel. External cooling water is connected through the arranged water supply port and the reflux port to enter the inner flow channel to promote the condensation of internal steam.

[0014] Beneficial effects: This high-efficiency and energy-saving evaporation concentrator uses an impeller to pump the liquid medicine to a high place, and then flows down through the top flow plate and the multi-stage laminar flow plate in sequence. In this process, the top flow plate and the laminar flow plate can increase the contact area between the liquid medicine and the air, thereby increasing the evaporation rate of the water in the liquid medicine. At the same time, the condensing kettle adopts an externally surrounded water-cooled structure, which can create a higher temperature difference on the inner wall, thereby promoting the steam condensation process, thereby improving the efficiency of the entire evaporation and concentration process.

[0023] The condensing kettle 2 also includes an inner cylinder 21, an inner spiral partition 22, a condensing plate 23 and a partition cover 25. The inner cylinder 21 is embedded and installed inside the condensing kettle 2, the inner spiral partition 22 is embedded and installed between the outer wall of the inner cylinder 21 and the condensing kettle 2, and several condensing plates 23 are installed obliquely on the inner wall of the inner cylinder 21.

A drain outlet 26 is installed at the bottom edge of the condensing kettle 2, and the drain outlet 26 is connected from the inside of the condensing kettle 2 to the partition cover 25.

[0024] As a further solution of the utility model: the impeller 11 is connected to the motor 16, and the impeller 11 is driven by the motor 16 to rotate. The liquid to be evaporated in the evaporator 1 enters the interior through the liquid inlet of the impeller 11, and then the liquid is pumped into the liquid supply pipe 12 through the impeller 11, and the liquid slowly flows out from the top of the liquid supply pipe 12.

[0025] As a further solution of the utility model: the edge of the top flow plate 14 is arc-shaped toward the bottom, and the liquid medicine slowly slides downward through the arc-shaped edge of the top flow plate 14 and falls into the groove 131 of the laminar flow plate 13 below.

After heating, the water in the medicine liquid will evaporate into water vapor and enter the condensation kettle 2 through the steam interface 24. In this process, the external cooling water flows through the inner spiral inner flow channel 211, so that the inner cylinder 21 forms a temperature difference between the inside and the outside. When the steam rises, it is condensed by the cold, and the water droplets will adhere to the bottom of the condensation plate 23 and slide along the inner wall of the inner cylinder 21 to between the partition cover 25 and the condensation kettle 2, and be discharged through the drain port 26. It should be noted here that the motor 16 drives the impeller 11 to pump the medicine liquid to the top of the liquid supply pipe 12, and flows to the groove 131 of the lower laminar plate 13 through the edge of the top flow plate 14. After overflowing, it falls into the groove 131 of the next-level laminar plate 13 through the outer arc 132, and the medicine liquid overflowing through the inner arc 133 directly falls into the lower medicine liquid pool, repeating the above process to increase the contact area between the medicine liquid and the air, thereby improving the evaporation rate.
