Description

Technical Field

[0001] The utility model relates to the technical field of vacuum evaporators, in particular to a vacuum evaporator with condensed water suction. Background Art

[0002] The evaporator is a commonly used device in the production of food, beverages, traditional Chinese medicine, etc. It uses a medium for heat exchange during heating to achieve the purpose of heating, evaporation and concentration. The vacuum evaporator reduces the boiling point through vacuum pressure reduction, has a high utilization rate of thermal energy, and saves energy.

[0003] When the condensed water in the vacuum evaporator cannot be discharged into the water pool but flows back into the vacuum evaporator, the vacuum degree will be reduced and may even dilute the concentrated alkali in the evaporator, affecting its operation. What is more serious is that if the condensed water flows back into the vacuum pump, the vacuum pump may be damaged due to the uneven hot and cold between the cylinder and the piston. Secondly, the condensed water in the evaporator contains a slight alkali, which not only pollutes the water quality and limits the application of the condenser, but also wastes a large amount of caustic soda. The reasons for the alkali in the condensed water may include excessively high liquid level or cracks in the steel pipe in the heating chamber. When the solution enters the vacuum evaporator, it generally enters vertically to exchange heat with the medium. The heat exchange time is short, which easily affects the evaporation effect of the solution when the vacuum evaporator is used. Utility Model Content

[0011] Preferably, a baffle is rotatably connected to the inner wall of the air intake pipe, the baffle covers the surface of the air guide port, an extension spring is fixed to one side of the baffle, and one end of the extension spring is fixedly connected to the inner wall of the air intake pipe.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the vacuum evaporator with condensed water suction not only avoids the service life of the vacuum evaporator being affected by the backflow of condensed water when the vacuum evaporator is in use, but also improves the evaporation effect of the solution when the vacuum evaporator is in use;

[0013] 1. By providing a suction mechanism, the steam pipe can be connected to the air inlet pipe before use, so that the steam enters the condenser for condensation and liquefies into condensed water. At the same time, the control row of keys is operated to control the water pump to suck the condensed water inside the condenser and guide the condensed water to the inside of the water tank.

At the same time, the feed liquid is guided to the inside of the heat-conducting inner tube through the feed pipe. Then, the control row key is operated to close the control valve and start the vacuum pump to evacuate the inside of the vacuum evaporator. The boiling point is reduced by vacuum pressure reduction. At this time, since the heat-conducting inner tube is a spiral structure, the flow time of the feed liquid in the heat-conducting outer tube can be increased, and its evaporation effect can be increased. During the flow of the feed liquid, it is heated and vaporized by the shell-side heating medium. The generated steam and liquid phase enter the separation chamber at the bottom of the vacuum evaporator together. At this time, the feed liquid can be discharged through the discharge pipe, and the steam can be discharged through the steam pipe to realize the high-efficiency vacuum evaporation function of the vacuum evaporator, thereby improving the evaporation effect of the solution when the vacuum evaporator is used.

[0021] The utility model provides a vacuum evaporator with condensed water suction. Figure 1 and Figure 2 As shown, it includes a bottom plate 1 and a vacuum evaporation tank 102.

An air inlet pipe 105 is fixed on one side of the bottom position of the condenser 103. The air inlet pipe 105 is connected to the steam pipe 106.

[0022] Furthermore, if Figure 2 and Figure 3As shown, a vacuum evaporation mechanism 2 is provided on the surface of the vacuum evaporation tank 102, and the vacuum evaporation mechanism 2 is composed of a vacuum evaporation component 201 and a vacuum pump 202. The vacuum pump 202 is installed on the surface of the vacuum evaporation tank 102, and the model of the vacuum pump 202 can be selected from the SK series. The input end of the vacuum pump 202 is electrically connected to the output end of the control row key 101, and one end of the vacuum pump 202 extends to the inside of the vacuum evaporation tank 102.

The model of the control valve 2013 can be selected from the TM series. The input end of the control valve 2013 is electrically connected to the output end of the control row key 101. A heat-conducting outer tube 2015 is fixed inside the vacuum evaporation tank 102, and the heat-conducting outer tube 2015 is connected to the liquid guide tube 2012. A heat-conducting inner tube 2016 is installed inside the heat-conducting outer tube 2015. The structure of the heat-conducting inner tube 2016 is a spiral structure, and the two ends of the heat-conducting inner tube 2016 are respectively connected to the discharge tube 2011 and the feed tube 2014.

[0023] When in use, the hot liquid medium is guided to the inside of the heat-conducting outer tube 2015 through the liquid guiding tube 2012, and at the same time, the feed liquid is guided to the inside of the heat-conducting inner tube 2016 through the feeding tube 2014. Then, the control row key 101 is operated to control the control valve 2013 to be closed, and the vacuum pump 202 is turned on to make the vacuum pump 202 evacuate the inside of the vacuum evaporation tank 102, and reduce the boiling point by vacuum pressure reduction. At this time, since the heat-conducting inner tube 2016 is a spiral structure, the flow time of the feed liquid in the heat-conducting outer tube 2015 can be increased, and its evaporation effect can be increased. During the flow of the feed liquid, it is heated and vaporized by the shell-side heating medium, and the generated steam and liquid phase enter the separation chamber at the bottom of the vacuum evaporation tank 102 together. At this time, the feed liquid can be discharged through the discharge pipe 2011, and the steam is discharged through the steam pipe 106, so as to realize the efficient vacuum evaporation function of the vacuum evaporator.

[0024] Furthermore, if Figure 2 and Figure 4As shown, a suction mechanism 3 is arranged above the bottom plate 1, a water pump 301 and a backflow prevention component 302 are arranged inside the suction mechanism 3, a water pump 301 is installed on the surface of the water tank 104, the model of the water pump 301 can be selected from the SLG series, an input end of the water pump 301 is electrically connected to an output end of the control row key 101, one end of the water pump 301 extends to the inside of the water tank 104, and the other end of the water pump 301 is connected to the condenser 103 through a pipeline, and an anti-backflow component 302 is arranged inside the air inlet pipe 105. The interior of component 302 includes an air guide port 3021, a fixed plate 3022, an extension spring 3023 and a baffle 3024. The fixed plate 3022 is fixed inside the air intake pipe 105, and the air guide port 3021 is opened on the surface of the fixed plate 3022. The inner wall of the air intake pipe 105 is rotatably connected with a baffle 3024, and the baffle 3024 covers the surface of the air guide port 3021. An extension spring 3023 is fixed on one side of the baffle 3024, and one end of the extension spring 3023 is fixedly connected to the inner wall of the air intake pipe 105.

[0025] Before use, the steam pipe 106 can be connected to the air inlet pipe 105 to allow the steam to enter the condenser 103 for condensation and to liquefy into condensed water. At the same time, the control row key 101 is operated to control the water pump 301 to work, so as to suck the condensed water inside the condenser 103 and guide the condensed water to the inside of the water tank 104. At the same time, when the steam enters the air inlet pipe 105, the steam pushes the baffle 3024 to open the baffle 3024, so that the steam enters the condenser 103 through the air guide port 3021. If the condensed water flows back, at this time, the baffle 3024 can be thrusted by the extension spring 3023 to block the air guide port 3021. The condensed water can be intercepted by the baffle 3024 to prevent the condensed water from flowing back, so as to realize the vacuum evaporator's function of sucking and preventing backflow of condensed water.

[0026] Working principle: When in use, firstly, the hot liquid medium is guided to the inside of the heat-conducting outer tube 2015 through the liquid guiding tube 2012, and at the same time, the feed liquid is guided to the inside of the heat-conducting inner tube 2016 through the feeding tube 2014, and then the control row key 101 is operated to control the control valve 2013 to be closed, and the vacuum pump 202 is turned on, so that the vacuum pump 202 evacuates the inside of the vacuum evaporation tank 102, and the boiling point is reduced by vacuum pressure reduction. At this time, since the heat-conducting inner tube 2016 is a spiral structure, the flow time of the feed liquid in the heat-conducting outer tube 2015 can be increased, and its evaporation effect can be increased. During the flow of the feed liquid, it is heated and vaporized by the shell-side heating medium, and the generated steam and the liquid phase enter the separation chamber at the bottom of the vacuum evaporation tank 102 together. At this time, the feed liquid can be discharged through the discharge pipe 2011, and the steam is discharged through the steam pipe 106, so as to realize the high-efficiency vacuum evaporation function of the vacuum evaporator, thereby improving the evaporation effect of the solution when the vacuum evaporator is used.

[0027] Before use, the steam pipe 106 can be connected to the air inlet pipe 105, so that the steam enters the condenser 103 and condenses, and the steam is liquefied into condensed water. At the same time, the control row key 101 is operated to control the water pump 301 to suck the condensed water inside the condenser 103 and guide the condensed water to the inside of the water tank 104. At the same time, when the steam enters the air inlet pipe 105, the steam pushes the baffle 3024 to open the baffle 3024, so that the steam passes through the air guide port 3024. 21 enters the interior of the condenser 103. If the condensed water flows back, at this time, the extension spring 3023 can generate a thrust on the baffle 3024, so that the baffle 3024 blocks the air guide port 3021. The condensed water can be intercepted by the baffle 3024 to prevent the condensed water from flowing back, so as to realize the vacuum evaporator's function of sucking and preventing the condensed water from flowing back, thereby avoiding the service life of the vacuum evaporator being affected by the backflow of condensed water when in use, and finally completing the use of the vacuum evaporator.
