This equipment is based on the principle of physical mechanical screening, and uses a membrane material with selective separation function to achieve the separation between different components.

[0003] In the process of selective solution separation of the existing membrane separation equipment, when the filter element of the membrane is not cleaned after long-term use, some parts of the membrane will be blocked. When separating the liquid again to obtain the solution, the required molecular substances will be filtered out, and the obtained solution is not the desired solution, and it needs to be filtered again, which is time-consuming and laborious, and increases the workload of the staff. Content of the Utility Model

[0004] In order to overcome the deficiency that the permeability of the filter membrane is improved after the filter element is used for a long time in the prior art, one of the purposes of the utility model is to provide a special acid- and alkali-resistant membrane separation equipment.

[0005] One of the purposes of the utility model is realized by adopting the following technical scheme: a special acid- and alkali-resistant membrane separation equipment, including a base: a high-pressure pump one, a solution tank, a water tank, a high-pressure pump two, and a display screen are fixedly connected to the upper side of the base.

The lower side of the pipeline four is fixedly connected to the water tank. A flange two is fixedly connected between the pipeline four and the filtering component. It is beneficial for the filtration and collection of the solution.

[0007] According to the special acid- and alkali-resistant membrane separation equipment, a pipeline one is fixedly connected between the solution tank and the high-pressure pump one. It is convenient for the solution to be filtered in the high-pressure pump one.

[0008] According to the special acid- and alkali-resistant membrane separation equipment, a water outlet is arranged on the outside of the water tank. It is convenient for the staff to handle the filtered liquid.

[0009] According to the described special acid- and alkali-resistant membrane separation equipment, a valve one is provided on the outer side where the second pipeline and the third pipeline intersect. This facilitates controlling the solution for ultrafiltration, nanofiltration, and reverse osmosis.

[0010] According to the described special acid- and alkali-resistant membrane separation equipment, a first flange is fixedly connected between the third pipeline and the filtration assembly. This is beneficial to the sealing of the pipeline.

[0011] According to the described special acid- and alkali-resistant membrane separation equipment, there are three of the third pipelines and valve ones, and there are three filtration assemblies which are respectively an ultrafiltration assembly, a nanofiltration assembly, and a reverse osmosis assembly. This provides multiple function options and saves the time for staff to replace the filtration assemblies.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, it should not be construed as a limitation on the protection scope of the present utility model.

[0021] Refer to Figures 1-3, A special acid- and alkali-resistant membrane separation device, including a base 1: On the upper side of the base 1, a first high-pressure pump 2, a solution tank 3, a water tank 12, a second high-pressure pump 15, and a display screen 17 are fixedly connected. On the outside of the first high-pressure pump 2, a second pipeline 5 is fixedly connected. On the outside of the second pipeline 5, a third pipeline 6 is fixedly connected. Below the third pipeline 6, a filtration component 9 is provided. On the outside of the filtration component 9, a fifth pipeline 14 is fixedly connected. On the outside where the fifth pipeline 14 intersects with the filtration component 9, a second valve 18 is provided. The fifth pipeline 14 is fixedly connected to the second high-pressure pump 15. Between the second high-pressure pump 15 and the water tank 12, a sixth pipeline 16 is fixedly connected. Below the filtration component 9, a fourth pipeline 10 is provided. The lower side of the fourth pipeline 10 is fixedly connected to the water tank 12. Between the fourth pipeline 10 and the filtration component 9, a second flange 11 is fixedly connected. Between the solution tank 3 and the first high-pressure pump 2, a first pipeline 4 is fixedly connected. On the outside of the water tank 12, a water outlet 13 is provided. On the outside where the second pipeline 5 intersects with the third pipeline 6, a first valve 7 is provided. Between the third pipeline 6 and the filtration component 9, a first flange 8 is fixedly connected. There are three sets of the third pipeline 6 and the first valve 7, and there are three filtration components 9, which are respectively an ultrafiltration component, a nanofiltration component, and a reverse osmosis component. The PLC controller is electrically connected to the first high-pressure pump 2, the second high-pressure pump 15, and the display screen 17, facilitating the operation of the control components. During the working process, the staff puts some solutions that need to be filtered into the solution tank 3, and then the staff operates the display screen 17 to select the filtration method. From right to left, they are ultrafiltration, nanofiltration, and reverse osmosis. After selection, since both the first valve 7 and the second valve 18 are in the closed state, when the first valve 7 is in the closed state, the solution will only flow downward from the second pipeline 5 to the filtration component 9. When the first valve 7 is opened, the solution will not flow to the filtration component 9. The second valve 18 can control the diversion of the solution. One part flows to the filtration component 9, and the other part flows to the fifth pipeline 14. The ratio can be adjusted by the staff. When the ultrafiltration method is selected, first, all the first valves 7 are closed. Start the first high-pressure pump 2. The solution flows from the first pipeline 4 through the second pipeline 5 to the third pipeline 6, and then let all the second valves 18 flow through the filtration component 9. After the solution is filtered, it enters the water tank 12 from the fourth pipeline 10. Generally, the solution is sufficient for use and does not need to be filtered repeatedly. When the filterability in the filtration component 9 has not been cleaned for a long time and its filter element is blocked, the filtered solution will surely not be the desired solution. At this time, start the second high-pressure pump 15 and stop the first high-pressure pump 2, driving the solution in the water tank 12 to enter the fifth pipeline 14 from the sixth pipeline 16. Then the staff controls the diversion of the second valve 18 to let the solution in the fifth pipeline 14 enter the filtration component 9, forming a closed circulation system to unclog the blocked filter element with the solution, obtaining the desired solution and also unclogging the filter element, indirectly extending the service life of the filter element in the filtration component 9. When the solution is finally filtered, it can be directly taken out for use from the water outlet 13.

[0022] Working principle: The staff collects the waste liquid into the solution tank 3, then starts the first high-pressure pump 2 for liquid transportation. The staff operates the display screen 17 to select the filtration method, and finally makes the solution enter the appropriate filtration component 9 for filtration. When the solution obtained by filtration is not the desired solution, start the second high-pressure pump 15 to perform repeated filtration until the solution is the desired liquid.

[0023] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the relevant technical field, various changes can be made without departing from the purpose of the present utility model.
