Description

Technical Field

[0001] The utility model relates to the technical field of daily chemical preparation production, in particular to a separation system for daily chemical preparation production. Background Technique

[0002] Daily chemical preparations, also known as daily chemical products or daily chemical goods, are scientific and technological chemical products used in people's daily lives. These products are mainly used for personal hygiene, beauty care, household cleaning and washing, etc. Common washing products include detergents, cleaning agents, etc.

[0003] Among them, the cleaning agent is a liquid cleaning product used to wash clothes, clean utensils or clean furniture, etc. In the production process, it is usually necessary to use the method of distillation to separate the excess water of the cleaning agent for concentration and improve the purity.

[0004] The Chinese utility model patent with the publication number of CN216023218U discloses a distillation device for cleaning agent production, including a distillation kettle and a cooling pipe. The bottom end of the distillation kettle is fixedly connected with a support column, an insulating layer is fixed outside the distillation kettle, one side of the distillation kettle is communicated with a feed pipe, and a flow valve is arranged on the feed pipe. A top cover is arranged on the top of the distillation kettle, a through hole is opened in the middle of the top cover, the cooling pipe passes through the through hole and is fixedly connected with the top cover. One end of the cooling pipe located inside the distillation kettle is fixedly connected with a steam collection tank. The cooling pipe is successively provided with an over-distillation alarm device, a steam filtration device and a condensation device. The other end of the cooling pipe is communicated with a liquid collection tank, and an observation window is arranged on the distillation kettle. By adding a pressure gauge, the rate of cleaning agent steam generation can be effectively displayed. When the steam generation rate is low, the heating heat can be increased to improve the efficiency. When over-distillation occurs, the pressure valve opens and the alarm is turned on, reducing the potential safety hazard. By arranging a filter screen at the feed port, impurities are effectively prevented from accumulating in the distillation kettle and affecting the distillation efficiency.

[0005] However, when this device is actually used, the conventional distillation kettle usually adopts high-quality electric heaters evenly distributed at the bottom of the distillation kettle jacket to heat the heat-conducting oil in the jacket, and then transfer the heat through the oil to heat the raw materials for distillation. This method is prone to low heating efficiency due to the influence of the heat conduction area, resulting in large energy consumption and poor distillation separation effect.

Detailed implementation mode

[0026] Now, the present utility model will be further described in detail with reference to the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0027] It should be noted that the separation system for the production of daily chemical preparations of the present invention is preferably applicable to the production separation and distillation of detergents whose main components include one or more of surfactants, natural plant extracts, sodium hydroxide, sodium silicate or triethanolamine.

[0028] As Figure 1 shown, a separation system for the production of daily chemical preparations includes: a raw material tank 1, a preheating assembly, a distillation mechanism and a filtration assembly connected in sequence through pipelines; the distillation mechanism includes: an evaporator 2, a separator 3 and a steam compressor 4 connected in sequence through pipelines; the interior of the evaporator 2 is composed of a heating chamber 21 and an evaporation chamber 22. A heating element 23 is arranged outside the heating chamber 21 of the evaporator 2, and a spiral pipeline 24 is arranged inside the heating chamber 21. Both ends of the spiral pipeline 24 penetrate to the outside of the evaporator 2; the top of the evaporator 2 is communicated with the side surface of the separator 3 through a pipeline; the input end of the steam compressor 4 is communicated with the top of the separator 3 through a pipeline, and the output end is communicated with one end of the spiral pipeline 24 through a pipeline.

[0029] It should be noted that when the raw material enters the heating chamber 21 inside the evaporator 2, the raw material is heated by the heating element 23, so that it gradually evaporates for distillation. The evaporated steam enters the steam chamber upward and then enters the separator 3. With the cooperation of the separator 3, the separation of the concentrated liquid and the secondary steam is completed. After the secondary steam is pressurized by the steam compressor 4, it becomes high-temperature and high-pressure steam and is input into the spiral pipeline 24, which can heat the raw material with the secondary steam in the heating chamber 21, thereby reducing the heating energy consumption of the heating element 23 itself. At the same time, since the spiral pipeline 24 is spiral in shape, the contact area and residence time can be increased, realizing the secondary utilization of steam, effectively improving the heating efficiency, and reducing the energy consumption required to improve the distillation separation effect.

[0030] In some embodiments, the preheating assembly includes: a heater 5, and a feed pipe 51 and a condensate pipe 52 passing through the heater 5; one end of the feed pipe 51 communicates with the side of the raw material tank 1, and the other end communicates with the bottom of the evaporator 2; one end of the condensate pipe 52 communicates with one end of the spiral pipeline 24.

[0031] It should be noted that when the raw material passes through the heater 5 via the feed pipe 51, the raw material can be preheated to a certain temperature, increasing the initial temperature of the raw material, thereby reducing the energy consumption required for subsequent heating and evaporation, improving the evaporation efficiency. At the same time, the condensate formed by the heat exchange inside the heating chamber 21 by the spiral pipeline 24 will enter the condensate pipe 52 from one end of the spiral pipeline 24. When passing through the heater 5, it can exchange heat with the raw material in the feed pipe 51 using the residual heat, providing a certain preheating effect on the raw material, thereby reducing the heating energy consumption of the heater 5 itself, improving the energy utilization efficiency, and thus reducing the overall production cost.

[0032] In some embodiments, a first feed pump 6 is provided on the feed pipe 51 between the heater 5 and the evaporator 2; with the cooperation of the first feed pump 6, the preheated raw material can be transported into the interior of the evaporator 2.

[0033] In some embodiments, the filtration assembly includes: a filtration tank 7, and a first filter screen 71, a second filter screen 72, and a third filter screen 73 sequentially arranged inside the filtration tank 7 from top to bottom; the side of the filtration tank 7 at the top of the first filter screen 71 communicates with the bottom of the separator 3 through a pipeline.

[0034] It should be noted that the pore diameter of the third filter screen 73 is smaller than that of the second filter screen 72 and the first filter screen 71 in sequence; when the concentrated raw material separated by the separator 3 enters the interior of the filtration tank 7, it will pass through the first filter screen 71, the second filter screen 72, and the third filter screen 73 from top to bottom for filtration. Since the pore diameter of the third filter screen 73 is smaller than that of the second filter screen 72 and the first filter screen 71 in sequence, it can filter impurities or agglomerates existing in the distilled concentrated raw material multiple times, thereby further improving the distillation quality.

[0035] In some embodiments, a second feed pump 8 is provided on the pipeline connecting the filtration tank 7 and the separator 3; with the cooperation of the second feed pump 8, the concentrated raw material separated inside the separator 3 can be transported into the interior of the filtration tank 7.

[0036] In some embodiments, the heating element 23 has a jacket structure, and the heating element 23 wraps around the outside of the evaporator 2 located in the heating chamber 21. The heating element 23 heats by means of thermal radiation or heat conduction.

[0037] In some embodiments, a raw material inlet 9 is provided on the side of the raw material tank 1 near the top, and a raw material outlet 91 is provided on the side near the bottom; a material inlet 92 is provided at the bottom of the evaporator 2, and a first steam outlet 93 is provided at the top; a steam inlet 94 is provided on the side of the separator 3, a second steam outlet 95 is provided at the top, and a concentrated liquid outlet 96 is provided at the bottom; a concentrated liquid inlet 97 is provided on the side of the filtration tank 7 near the top, and a material outlet 98 is provided on the side near the bottom.

[0038] It should be noted that valves are provided on the raw material outlet 91, the material inlet 92, the concentrated liquid outlet 96, and the material outlet 98. The valves include, but are not limited to, check valves, flow valves, pneumatic valves, electric valves, or globe valves; the raw materials can be stored in the raw material tank 1 through the raw material inlet 9. Through the settings of the raw material outlet 91 and the material inlet 92, the raw materials inside the raw material tank 1 can enter the inside of the evaporator 2 through the feeding pipe 51 therebetween. Through the settings of the first steam outlet 93 and the steam inlet 94, the steam inside the evaporator 2 can enter the inside of the separator 3 through the pipeline therebetween. Through the settings of the concentrated liquid outlet 96 and the concentrated liquid inlet 97, the concentrated raw materials inside the separator 3 can enter the inside of the filtration tank 7 through the pipeline therebetween. Through the setting of the material outlet 98, the concentrated raw materials that have been filtered in the filtration tank 7 can be discharged.

[0039] When the utility model is in use, raw materials are stored in the raw material tank 1 through the raw material inlet 9. The raw materials are conveyed to the evaporator 2 through the feeding pipe 51. When passing through the heater 5, the raw materials can be preheated to a certain temperature to increase the initial temperature of the raw materials. With the cooperation of the first feeding pump 6, the preheated raw materials can be conveyed into the interior of the evaporator 2. When the raw materials enter the heating chamber 21 inside the evaporator 2, the raw materials are heated by the heating element 23, causing them to gradually evaporate for distillation. The evaporated steam rises into the steam chamber and enters the separator 3. With the cooperation of the separator 3, the separation of the concentrated liquid and the secondary steam is completed. After the secondary steam is pressurized by the steam compressor 4, it becomes high-temperature and high-pressure steam and is input into the interior of the spiral pipeline 24, which can heat the raw materials with the secondary steam in the heating chamber 21, thereby reducing the heating energy consumption of the heating element 23 itself. At the same time, the condensate formed by the heat exchange in the heating chamber 21 by the spiral pipeline 24 will enter the condensate pipe 52 from one end of the spiral pipeline 24. When passing through the heater 5, it can exchange heat with the raw materials in the feeding pipe 51 using the residual heat, providing a certain preheating effect on the raw materials, thereby reducing the heating energy consumption of the heater 5 itself. With the cooperation of the second feeding pump 8, the concentrated raw materials separated in the separator 3 can be conveyed into the interior of the filter tank 7. When the concentrated raw materials separated by the separator 3 enter the interior of the filter tank 7, they will pass through the first filter screen 71, the second filter screen 72, and the third filter screen 73 from top to bottom for filtration. Since the pore diameter of the third filter screen 73 is smaller than that of the second filter screen 72 and the first filter screen 71 in sequence, the impurities or lumps existing in the distilled concentrated raw materials can be filtered multiple times, thereby further improving the distillation quality.
