The core component of water purification equipment is the reverse osmosis filter element with reverse osmosis membrane, and its quality directly affects the water purification effect of water purification equipment.

[0003] During the production process, the reverse osmosis filter element after the water test needs to be immersed in the protective liquid to absorb the protective liquid to prevent bacteria from breeding in the reverse osmosis filter element, avoid the reverse osmosis membrane in the reverse osmosis filter element from being contaminated and oxidized, and at the same time extend the service life of the reverse osmosis filter element. However, in the prior art, the reverse osmosis filter element is mainly placed in an open container containing protective liquid for soaking. Although this method is easy to operate, to ensure that the reverse osmosis filter element fully absorbs the protective liquid, the reverse osmosis filter element needs to be soaked in the protective liquid for a long time, which undoubtedly greatly increases the production cycle of the reverse osmosis filter element. Therefore, there is an urgent need for a device to shorten the soaking time of the reverse osmosis filter element in the protective liquid. Summary of the invention

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Figure 1 1 is a cross-sectional view of a device for promoting a reverse osmosis filter element to absorb a protective liquid according to an embodiment of the present invention. Figure 1 As shown, an embodiment of the present invention provides a device 100 for promoting a reverse osmosis filter element to absorb a protective liquid, the device 100 comprising an open container 1 and a driving component 2 connected to the open container 1. The open container 1 is used to contain the protective liquid and the reverse osmosis filter element immersed in the protective liquid. The driving component 2 can force the protective liquid in the open container 1 to move. The protective liquid is often selected as a mixed solution of a sodium bisulfite solution with a concentration of 0.5%-1.0% and a glycerol solution with a concentration of 8%-10%.

[0023] According to an embodiment of the present invention, the main improvement of the device 100 for promoting the reverse osmosis filter element to absorb the protective liquid is to add a driving component 2 to the existing open container 1 for soaking the reverse osmosis filter element, and the driving component 2 forces the protective liquid in the open container 1 to move, which can not only maintain the concentration of the protective liquid at various positions in the open container 1 to remain basically consistent, ensuring that the reverse osmosis filter element can fully absorb the protective liquid with a concentration that meets the standard, but also accelerate the absorption of the protective liquid by the reverse osmosis filter element. In this way, the device 100 can shorten the time that the reverse osmosis filter element is immersed in the protective liquid while ensuring that the reverse osmosis filter element fully absorbs the protective liquid, which can not only improve the production rate of the reverse osmosis filter element, but also shorten the production cycle of the reverse osmosis filter element. In addition, the device 100 has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement and promote.

[0024] In this embodiment, the driving component 2 includes a delivery pump 21 and a liquid outlet pipe 22 connected to the open container 1 and the delivery pump 21 and capable of recovering the protection liquid in the open container 1, and a liquid return pipe 23 connected to the delivery pump 21 and capable of returning the protection liquid to the open container 1. That is, the driving component 2 in this embodiment extracts the protection liquid in the open container 1 through the liquid outlet pipe 22 through the delivery pump 21, and returns the protection liquid to the open container 1 through the liquid return pipe 23, thereby achieving the purpose of forcing the protection liquid in the open container 1 to move. Among them, using the delivery pump 21 as the main power source of the driving component 2 can effectively increase the flow speed of the protection liquid, and returning the protection liquid to the open container 1 through the liquid outlet pipe 22 can promote the rapid fusion of protection liquids of different concentrations at various positions in the open container 1, which can further avoid the situation where the concentration of the protection liquid around the reverse osmosis filter element is too low, and ensure that the reverse osmosis filter element can fully absorb the protection liquid with a concentration that meets the standard.

[0025] In this embodiment, there are multiple liquid return pipes 23, but the specific number is not specifically required in this embodiment. Those skilled in the art can choose according to the size of the open container 1, the performance parameters of the reverse osmosis filter element, and the physical and chemical properties of the protective medium (such as a mixture of sodium bisulfite and glycerol) in the protective liquid. However, preferably, multiple liquid return pipes 23 are inserted into the open container 1 in a manner close to the inner wall of the open container 1, which can effectively avoid hindering the operator from placing the reverse osmosis filter element into the open container 1 due to the liquid return pipe 23 being set in the middle or other positions of the open container 1. More preferably, when the cross-section of the inner cavity of the open container 1 is polygonal, multiple liquid return pipes 23 are inserted into it close to the corners of the inner wall of the open container 1; when the cross-section of the inner cavity of the open container 1 is circular, multiple liquid return pipes 23 are inserted into it close to the inner wall of the open container 1 and are evenly spaced along the circumference.

[0026] In this embodiment, the device 100 also includes a bracket 3 for supporting the open container 1, and the delivery pump 21 is arranged in the bracket 3 and connected to the open container 1 and / or the bracket 3. By setting the bracket 3, a certain space can be left at the bottom of the open container 1, so that the liquid outlet pipe 22 can be more easily connected to the bottom of the open container 1, and this can further improve the effect of merging the protective liquid of different concentrations at various positions in the open container 1, so as to better achieve the purpose of shortening the time for the reverse osmosis filter element to be immersed in the protective liquid while ensuring that the reverse osmosis filter element fully absorbs the protective liquid, thereby not only further improving the production rate of the reverse osmosis filter element, but also further shortening the production cycle of the reverse osmosis filter element. It should be noted that the bracket 3 is preferably a table leg structure or a sedan pole structure, and those skilled in the art can choose it according to the placement needs of the device 100, which will not be repeated here.

[0027] like Figure 2As shown, in this embodiment, the device 100 also includes a positioning device 4 that can be placed in the open container 1, and the positioning device 4 is used to accommodate the reverse osmosis filter element and position the reverse osmosis filter element. The positioning device 4 fixes the reverse osmosis filter element, which can effectively prevent the reverse osmosis filter element from moving with the protective liquid, thereby avoiding the reverse osmosis filter element from being bumped and damaged, and further ensuring the qualified rate of the reverse osmosis filter element product. At the same time, the positioning device 4 can also make the reverse osmosis filter element completely immersed in the protective liquid, which can promote the absorption of the protective liquid by the reverse osmosis filter element, and further shorten the time for the reverse osmosis filter element to be immersed in the protective liquid, thereby not only further improving the production rate of the reverse osmosis filter element, but also further shortening the production cycle of the reverse osmosis filter element.

[0028] In this embodiment, the positioning device 4 includes a basket 41 and an intermediate partition 42 arranged in the basket 41 and parallel to the bottom of the basket 41. A plurality of jacks that allow the reverse osmosis filter element to be inserted vertically are provided on the intermediate partition 42. Because the basket 41 has a hollow characteristic, it allows the protective liquid to freely enter and exit the basket 41 and improves the mixing effect of the protective liquid in each area, ensuring that the reverse osmosis filter element can fully absorb the protective liquid with a concentration that meets the standard. The jack of the intermediate partition 42 is used to keep the reverse osmosis filter element in a vertical state during immersion, which is conducive to thoroughly discharging the bubbles in the reverse osmosis filter element. The cooperation of the intermediate partition 42 and the intermediate partition 42 can achieve the immersion of multiple reverse osmosis filter elements at one time, and greatly facilitates the operator to take and place the reverse osmosis filter element.

[0029] like Figure 3As shown, in this embodiment, the device 100 also includes a temperature sensor 4 disposed in the open container 1 and capable of measuring the temperature of the protection liquid, an electric heater 5 disposed in the open container 1 and used to heat the protection liquid, and a control module 6 connected to the temperature sensor 4 and the electric heater 5, and the control module 6 can control the power and switch of the electric heater 5 according to the detection result of the temperature sensor 4. Among them, the temperature sensor 4 may include a thermocouple, a thermistor or a bimetallic strip, the electric heater 5 includes a ceramic heating tube, a quartz heating tube or a metal heating tube, and the control module 6 may include a programmable logic control component, a memory and an electronic component connected to the programmable logic control component, all of which belong to conventional choices of those skilled in the art and are not repeated here. When the temperature sensor 4 detects that the temperature of the protection liquid is lower than the optimal absorption temperature range (for example, 5°C-35°C), the control module 6 can turn on the electric heater 5 and heat the protection liquid, and select the power of the electric heater 5 according to the difference between the temperature detected by the temperature sensor 4 and the optimal absorption temperature range; when the temperature sensor 4 detects that the temperature of the protection liquid reaches the optimal absorption temperature range, the control module 6 can turn off the electric heater. This can further ensure the effect of the reverse osmosis filter element absorbing the protective liquid, so as to better achieve the purpose of shortening the time for the reverse osmosis filter element to be immersed in the protective liquid while ensuring that the reverse osmosis filter element fully absorbs the protective liquid. It should be noted that those skilled in the art can determine the optimal absorption temperature range of the protective liquid according to the type of protective medium in the protective liquid and its physical and chemical parameters, which belongs to the conventional choice in the technical field, and the selection of the power of the electric heater is also a common means in the field, which will not be repeated here.

[0030] like Figure 3 As shown, in this embodiment, the device 100 also includes a reminder device 8 and a liquid level sensor 7 disposed in the open container 1 and capable of measuring the liquid level of the protection liquid. The liquid level sensor 7 is connected to the control module 6, so that the control module 6 can display and / or broadcast the detection result of the liquid level sensor through the reminder device 8. This can prompt the operator to add or replace the protection liquid in time when the height of the protection liquid cannot immerse the reverse osmosis filter element, thereby better ensuring the effect of the reverse osmosis filter element absorbing the protection liquid and shortening the time for the reverse osmosis filter element to be immersed in the protection liquid. Among them, the liquid level sensor may include a float liquid level sensor, a capacitive liquid level sensor or a magnetostrictive liquid level sensor.

[0031] like Figure 3As shown, in the present embodiment, an alarm 9 and a sensing module 10 that can be forced to generate a sensing signal when the reverse osmosis filter element has been placed in the open container 1 are also included. The sensing module 10 is connected to the control module 6, so that the control module 6 can start timing when receiving the sensing signal and trigger the alarm 9 to alarm after the timing reaches the set time period. Among them, the sensing module 10 can be selected as a piezoelectric switch or a photoelectric switch. For example, when the sensing module 10 is selected as a piezoelectric switch, if the reverse osmosis filter element is placed in the open container 1, the piezoelectric switch can be squeezed by the reverse osmosis filter element or the positioning device 4 to generate a sensing signal, thereby triggering the timing alarm function. The set time period refers to the time (for example, 6-24h) when the reverse osmosis filter element completes the absorption of the protective liquid. This can prompt the operator to take out the reverse osmosis filter element in time when the reverse osmosis filter element completes the absorption of the protective liquid, so as to avoid affecting the subsequent production links due to excessive soaking of the reverse osmosis filter element, thereby not only improving the production rate of the reverse osmosis filter element, but also shortening the production cycle of the reverse osmosis filter element.

[0032] In the above-mentioned embodiment, the reminder device 8 includes a speaker, a lamp and / or a display screen. When the reminder device 8 includes only a speaker, the operator can know the real-time liquid level of the protective liquid in the open container 1 through the broadcast; when the reminder device 8 includes only a lamp, the operator can know whether the liquid level of the protective liquid in the open container 1 is within the ideal range by the flickering of the lamp or the light of different colors emitted; when the reminder device 8 includes only a display screen, the operator can know the real-time liquid level of the protective liquid in the open container 1 through the content displayed on the display screen. In other embodiments, the reminder device 8 may also include any two or all of the display screen, lamp group and speaker, and those skilled in the art may choose according to their needs, which will not be described in detail here.

[0033] To sum up, the device 100 for promoting the reverse osmosis filter element to absorb the protective liquid provided by the present invention can solve the problem of the reverse osmosis filter element being immersed in the protective liquid for too long under the condition of ensuring that the reverse osmosis filter element fully absorbs the protective liquid. This can not only increase the production rate of the reverse osmosis filter element, but also shorten the production cycle of the reverse osmosis filter element.
