Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cold extraction processing, specifically to a reverse osmosis component of a cold extraction device. Background Technology
[0002] Existing reverse osmosis equipment contains at least two reverse osmosis stages connected by a series of pumps and pipelines. Each stage of the reverse osmosis system helps to further concentrate cosmetic raw material juices while separating the clear liquid from the concentrate. However, pretreatment is required before reverse osmosis treatment of cosmetic raw material juices. Pretreatment involves initial filtration of the cosmetic raw material juices to remove large particles that may foul the reverse osmosis membrane. Generally, larger particles in the cosmetic raw material juices are filtered through a filter screen. After a period of use, the filtered impurities remain on the filter screen, clogging some of the pores and affecting the filtration efficiency of the juice. Therefore, a reverse osmosis device for cold extraction of cosmetic raw material juices is proposed to solve the above problems. Utility Model Content
[0003] The purpose of this invention is to provide a reverse osmosis assembly with high cold extraction efficiency and convenient pipe cleaning.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] The device includes a base, on which a support rod is fixed. A reverse osmosis tube is fixed to the end of the support rod away from the base. There are two reverse osmosis tubes arranged in parallel. A first connecting pipe and a second connecting pipe connect the two reverse osmosis tubes. The first connecting pipe is located on the side of the two reverse osmosis tubes, and the second connecting pipe is located on the end face of the two reverse osmosis tubes. A reverse osmosis membrane assembly is installed inside each reverse osmosis tube. One end of the reverse osmosis tube is the inlet, and the other end is the outlet. One end of the second connecting pipe is connected to the outlet of one of the reverse osmosis tubes, and the other end is connected to the inlet of the other reverse osmosis tube. One end of the first connecting pipe is fixed near the inlet of one of the reverse osmosis tubes, and the other end is fixed near the outlet of the other reverse osmosis tube. The device is located below the two reverse osmosis tubes and also includes filter fittings fixed to the base.
[0006] Furthermore, the filter fitting includes a filter tube fixed on the base, a plurality of filter membranes fixed inside the filter tube, the plurality of filter membranes being arranged along the length of the filter tube, the plurality of filter membranes being equidistantly arranged, an inlet tube being fixed at the end face of the filter tube, and the other end of the inlet tube being connected to the end face of the reverse osmosis tube.
[0007] Furthermore, the second connecting pipe is connected to a first electric three-way valve on its side, the first electric three-way valve is connected to a water inlet pipe on its side, and the inlet pipe is also connected to a first water pump on its side. Several filter membranes face the inlet pipe and the filter pore size gradually decreases.
[0008] By adopting the above technical solution, the feed liquid can be filtered. After filtration pretreatment, impurities inside the subsequent feed liquid are reduced, thus improving the reverse osmosis operation.
[0009] Furthermore, an outlet tube is fixed to the side of the filter tube, and the number of outlet tubes is set to be consistent with the number of filter membranes, with each outlet tube located on the side of the filter membrane.
[0010] By adopting the above technical solution, it is convenient to clean the inside of the filter tube.
[0011] Furthermore, a first solenoid valve is fixed to the outside of the first connecting pipe, located on one side of the first solenoid valve, and a second water pump is also fixed to the outside of the first connecting pipe.
[0012] Furthermore, a second electric three-way valve is fixed to the outside of the second connecting pipe, and an outlet pipe is connected to the side of the second electric three-way valve. An inlet pipe is connected to the end of the filter pipe away from the outlet pipe. A second solenoid valve is also fixed to the outside of the second connecting pipe.
[0013] By adopting the above technical solution, the clarified liquid after passing through the first reverse osmosis tube first enters the interior of the second reverse osmosis tube to clean the reverse osmosis membrane module inside. At this time, the second electric three-way valve is controlled to open the outlet pipe end to export the clarified liquid. After the clarified liquid is cleaned, the second electric three-way valve is controlled to open the second connecting pipe. At this time, the concentrated liquid after passing through the first reverse osmosis tube enters the interior of the second reverse osmosis tube along the second connecting pipe for secondary reverse osmosis. Then, the concentrated liquid is exported by the collection pipe on the second reverse osmosis tube.
[0014] Furthermore, a collection tube is connected to the end of the reverse osmosis tube away from the second connecting tube.
[0015] By adopting the above technical solution, it is convenient to collect concentrated liquids in a centralized manner.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] 1. A filter tube is used to filter the incoming liquid. After filtration pretreatment, the impurities inside the subsequent incoming liquid are reduced, which can better facilitate reverse osmosis operation.
[0018] 2. A first connecting pipe is adopted. After passing through the first reverse osmosis pipe, the clear liquid first enters the interior of the second reverse osmosis pipe to clean the reverse osmosis membrane module inside. At this time, the second electric three-way valve is controlled to open the outlet pipe end to export the clear liquid. After the clear liquid is cleaned, the second electric three-way valve is controlled to open the second connecting pipe. At this time, the concentrated liquid that has passed through the first reverse osmosis pipe enters the interior of the second reverse osmosis pipe along the second connecting pipe for secondary reverse osmosis. Then, the concentrated liquid is exported by the collection pipe on the second reverse osmosis pipe, thus automatically completing the internal cleaning and reducing the impurity rate after reverse osmosis.
[0019] 3. A second electric three-way valve is adopted, which has a simple overall structure, facilitates replacement after liquid enters, and improves the reverse osmosis efficiency inside the reverse osmosis tube. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] 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.
[0027] Please refer to Figures 1-3. The present invention provides the following technical solution: It includes a base 1, a support rod 2 fixed on the base 1, and a reverse osmosis tube 3 fixed at the end of the support rod 2 away from the base 1. There are two reverse osmosis tubes 3, which are arranged in parallel. A first connecting pipe 4 and a second connecting pipe 5 are connected between the two reverse osmosis tubes 3. The first connecting pipe 4 is located on the side of the two reverse osmosis tubes 3, and the second connecting pipe 5 is located on the end face of the two reverse osmosis tubes 3. A reverse osmosis membrane assembly is set inside the reverse osmosis tube 3. One end of the reverse osmosis tube 3 is the inlet, and the other end is the outlet. One end of the second connecting pipe 5 is connected to the outlet of one of the reverse osmosis tubes 3, and the other end is connected to the inlet of the other reverse osmosis tube 3. One end of the first connecting pipe 4 is fixed near the inlet of one of the reverse osmosis tubes 3, and the other end is fixed near the outlet of the other reverse osmosis tube. It is located below the two reverse osmosis tubes 3. A filter tube 6 is also fixed on the base 1.
[0028] The filter tube 6 is fixed to the base 1. Several filter membranes 7 are fixed inside the filter tube 6, arranged equidistantly along its length. An inlet pipe 8 is fixed to one end of the filter tube 6, and the other end of the inlet pipe 8 is connected to the end of the reverse osmosis tube 3. The filter tube 6 is used for filtration after liquid inlet, thus pre-treating the solution before reverse osmosis. A first electric three-way valve 9 is connected to the side of the second connecting pipe 5, and an inlet pipe 10 is connected to the side of the first electric three-way valve 9. A first water pump 11 is also connected to the side of the inlet pipe 8. The filter membranes 7 face the inlet pipe 8, with gradually decreasing pore size.
[0029] The filter tube 6 has an outlet tube 12 fixed on its side. The number of outlet tubes 12 is the same as the number of filter membranes 7. Each outlet tube 12 is located on the side of the filter membrane 7.
[0030] Then, after the first water pump 11 is turned on, the liquid passing through the filter tube 6 enters the first reverse osmosis tube 3 through the outlet tube 12. After passing through the internal reverse osmosis membrane assembly, the clear liquid and the concentrated liquid are separated, and the clear liquid stays near the first connecting tube 4.
[0031] A first solenoid valve 13 is fixed to the outside of the first connecting pipe 4, located on one side of the first solenoid valve 13. A second water pump 14 is also fixed to the outside of the first connecting pipe 4.
[0032] After the second water pump 14 is turned on, the second water pump 14 draws clean liquid along the first connecting pipe 4 into the interior of the second reverse osmosis pipe 3 to clean the internal reverse osmosis membrane module.
[0033] Furthermore, a second electric three-way valve 15 is fixed to the outside of the second connecting pipe 5, and an outlet pipe 16 is connected to the side of the second electric three-way valve 15. An inlet pipe 17 is connected to the end of the filter pipe 6 away from the outlet pipe 12. A second solenoid valve 18 is also fixed to the outside of the second connecting pipe 5. A collection pipe 19 is connected to the end of the reverse osmosis pipe 3 away from the second connecting pipe 5. The specific process described above is as follows: the clear liquid after passing through the first reverse osmosis pipe 3 first enters the interior of the second reverse osmosis pipe 3 to clean the reverse osmosis membrane module inside. At this time, the second electric three-way valve 15 is controlled to open the outlet pipe 16 end to export the clear liquid. After the clear liquid is cleaned, the second electric three-way valve 15 is controlled to open the second connecting pipe 5. At this time, the concentrated liquid after passing through the first reverse osmosis pipe 3 enters the interior of the second reverse osmosis pipe 3 along the second connecting pipe 5 for secondary reverse osmosis. Then, the concentrated liquid is exported by the collection pipe 19 on the second reverse osmosis pipe 3.
[0034] The working principle of this utility model is as follows: The liquid is introduced along the filter tube 6. After being filtered by the filter tube 6, the liquid enters the first reverse osmosis tube 3 along the inlet tube 8 after the first water pump 11 is turned on. After reverse osmosis in the first reverse osmosis tube 3, the clear liquid enters the second reverse osmosis tube 3 along the first connecting tube 4. At this time, the second solenoid valve 18 on the second connecting tube 5 is closed, and the first solenoid valve 13 on the first connecting tube 4 and the second water pump 14 are opened. The clear liquid cleans the inside of the second reverse osmosis tube 3. After cleaning, it flows out along the outlet pipe 16 of the second electric three-way valve 15. Then, the second electric three-way valve 15 is controlled to close the outlet pipe 16 and open the second solenoid valve 18 to continue to introduce the concentrated liquid into the second reverse osmosis tube 3 for reverse osmosis. The concentrated liquid is collected along the collection pipe 19.
[0035] When cleaning the inside of all pipes, reverse the flow of clean water, close the first solenoid valve 13, clean the filter tube 6, and the impurities inside the filter tube 6 flow out along the outlet tube 12.
