Description

Technical Field

[0001] This utility model relates to the technical field of triple-effect concentration evaporation devices, specifically a triple-effect concentration evaporation device. Background Technology

[0002] In many industries such as chemical, pharmaceutical, food, and environmental protection, the evaporation and concentration of liquid materials is a crucial operational step. For example, in the pharmaceutical industry, various liquid drugs need to be concentrated to prepare high-purity drugs; in the chemical field, reaction mother liquor often needs to be concentrated to recover useful components or for further processing.

[0003] Chinese Patent Publication No. CN221513525U discloses a triple-effect evaporator with residual heat utilization. This utility model uses a triple-effect evaporator to evaporate and concentrate liquid materials. Through the combined use of the air inlet pipe and connecting pipe, the excess heat generated by the triple-effect evaporator during use can enter the inner cavity of the metal liner, thereby heating the water source in the water storage tank. Through the combined use of the water inlet pipe and water outlet pipe, the heated water source in the water storage tank is discharged while new water source is continuously added. Through the setting of the drain pipe, the excess water generated by steam can be discharged from the inner cavity of the metal liner, preventing liquid backflow in the inner cavity of the metal liner. This achieves the purpose of heating industrial water with the residual heat generated by triple-effect evaporation, effectively improving energy utilization efficiency.

[0004] However, as mentioned in the above solution, after the triple-effect evaporator is used, dust and impurities easily accumulate on the outer and inner walls. Scale buildup on the inner wall will significantly reduce the heat transfer efficiency of the evaporator, while dust accumulation on the outer wall will hinder the heat dissipation of the equipment, causing the system operating temperature to rise abnormally and reducing evaporation efficiency.

[0005] Therefore, it is necessary to invent a triple-effect concentration evaporation device. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1-4As shown, this utility model provides a triple-effect evaporation concentrator, including a base plate 1. A heater 11, a first-effect evaporator body 12, a heater 2 17, and a second-effect evaporator body 18 are fixedly mounted on the top of the base plate 1. The heater 11 is connected to the first-effect evaporator body 12, the first-effect evaporator body 12 is connected to the heater 2 17, and the heater 2 17 is connected to the second-effect evaporator body 18. A heater 3 19 and a triple-effect evaporator body 191 are fixedly mounted on the top of the base plate 1. The second-effect evaporator body 18 is connected to the third heater 19, and the third heater 19 is connected to the third-effect evaporator body 191. The top of the inner cavity of the first-effect evaporator body 12, the second-effect evaporator body 18, and the third-effect evaporator body 191 are all rotatably equipped with an outer cylinder 221. The bottom of the inner cavity of the first-effect evaporator body 12, the second-effect evaporator body 18, and the third-effect evaporator body 191 are all fixedly equipped with an inner tube 122. Multiple nozzles 123 are connected to the outer wall of the inner tube 122. The outer cylinder 221... The outer wall of the evaporator is provided with symmetrically distributed rectangular grooves 222. The top and bottom of the first-effect evaporator body 12, the second-effect evaporator body 18 and the third-effect evaporator body 191 are respectively fixed with L-shaped plates 13 and fixing blocks 124. A threaded rod 25 is rotatably provided between the L-shaped plate 13 and the fixing block 124. A ring 26 is threaded on the outer wall of the threaded rod 25. A cleaning brush plate 27 is detachably provided on the inner wall of the ring 26. A C-shaped scraper 223 is fixed on the outer wall of the outer cylinder 221. This three-effect evaporator is designed based on existing mature technology. The three-effect evaporator is an existing technology device that works based on the principle of multi-effect evaporation. It uses the secondary steam generated by the previous effect as the heating heat source for the next effect. The three evaporators (first effect, second effect and third effect) are connected in series to realize the repeated use of heat, thereby improving the energy utilization rate. The solution to be concentrated enters each effect evaporator in sequence, is heated and evaporated in the heating chamber, and the generated secondary steam enters the next effect as heating steam. The solution is continuously concentrated between each effect, and finally a high-concentration concentrate is obtained in the last effect. As an important component of the triple-effect evaporator, the heater provides heat to the evaporator through heat sources such as steam and electricity, enabling the solution to reach the evaporation temperature. In the entire system, the heat generated by the heater promotes the evaporation of the solution, while the evaporator utilizes the pressure and temperature differences between the effects to achieve the recycling of secondary steam and the continuous concentration of the solution. The two work together to complete the evaporation and concentration process. Since this is a mature technology, it will not be elaborated on further here.

[0019] Furthermore, the top of the first-effect evaporator body 12, the second-effect evaporator body 18, and the third-effect evaporator body 191 are all provided with a first synchronous wheel 22 and a second synchronous wheel 24. A synchronous belt 23 for transmission is provided between the first synchronous wheel 22 and the second synchronous wheel 24. A cylinder 2211 is fixedly provided at the bottom of the first synchronous wheel 22, and the cylinder 2211 is fixedly connected to the outer cylinder 221.

[0020] Furthermore, the top outer wall of the threaded rod 25 is fixedly connected to the synchronous pulley 24 to facilitate the rotation of the threaded rod 25.

[0021] Furthermore, a motor 14 is fixedly mounted on the top of the L-shaped plate 13. The output shaft of the motor 14 passes through the L-shaped plate 13 and is fixedly connected to the synchronous pulley 22 to facilitate the rotation of the synchronous pulley 22.

[0022] Furthermore, the inner tube 122 penetrates the bottom of the first-effect evaporator body 12, facilitating connection to an external water source.

[0023] Furthermore, the bottoms of the first-effect evaporator body 12, the second-effect evaporator body 18, and the third-effect evaporator body 191 are all connected by a drain pipe 126, through which the dirty water after cleaning can be discharged.

[0024] Furthermore, the outer wall of the ring 26 is threaded with symmetrically distributed screws 261, which movably penetrate the cleaning brush plate 27. When the cleaning brush plate 27 needs to be replaced or thoroughly cleaned, it can be removed by rotating the screws 261.

[0025] Working principle: When this solution is in use, when it is necessary to clean the inner and outer walls of the first-effect evaporator body 12, the second-effect evaporator body 18, and the third-effect evaporator body 191, the motor 14 can be started to rotate forward and backward, which in turn drives the first synchronous wheel 22 to rotate forward and backward. The first synchronous wheel 22 drives the second synchronous wheel 24 to rotate forward and backward through the synchronous belt 23, which in turn drives the threaded rod 25 to rotate forward and backward, thereby driving the ring 26 and the cleaning brush plate 27 to move up and down, thereby cleaning the outer walls of the first-effect evaporator body 12, the second-effect evaporator body 18, and the third-effect evaporator body 191, effectively removing the stains and impurities attached to the outer walls; At the same time, when the synchronous wheel 22 rotates, it will drive the cylinder 2211 to rotate, which in turn drives the outer cylinder 221 to rotate, which in turn drives the C-shaped scraper 223 to rotate, making it easier to scrape the inner wall and remove the dirt remaining on the inner wall. At the same time, the water source is connected to the inner pipe 122, and the water source is sprayed out through the nozzle 123. The sprayed water can rinse the inside of the evaporator body. Combined with the scraping of the C-shaped scraper 223, the scraped dirt is washed away in time, further improving the cleaning effect. When the cleaning brush 27 wears out after a period of use and needs to be replaced, or when a large amount of dirt accumulates and needs to be thoroughly cleaned, it can be removed by turning the screw 261. Then, the cleaning brush 27 can be deeply cleaned or replaced with a new cleaning brush 27. After cleaning or replacing the brush, it can be reinstalled on the inner wall of the ring 26 and the screw 261 can be tightened to ensure that the cleaning brush 27 can function properly in subsequent cleaning work.
