Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for demineralized water treatment. Background Technology
[0002] Demineralized water refers to the finished water obtained after removing suspended solids, colloids, and inorganic cations and anions from water using various water treatment processes. Demineralized water does not mean that all salts are completely removed. Due to technical limitations and cost considerations, trace amounts of impurities are permissible in demineralized water depending on its intended use. The fewer impurities in demineralized water, the higher its purity.
[0003] Existing demineralized water filtration devices typically use mechanical cleaning devices for filtration. When collecting the filtration material, staff not only have to replace filter parts during the maintenance of the entire device, but also regularly maintain and clean the cleaning components and remove impurities. However, this process is prone to problems such as waste clogging, which makes cleaning difficult.
[0004] Therefore, we propose a filtration device for demineralized water treatment. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a filtration device for demineralized water treatment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A filtration device for demineralized water treatment includes a filter box. A filter plate is fixedly installed on one side of the inner wall of the filter box. A permeable membrane is fixedly installed on the top of the filter plate. Multiple filter layers are fixedly installed on the top of the permeable membrane. A discharge box is fixedly installed on one side of the filter box. A water tank is fixedly installed at the bottom of the inner wall of the filter box. Drive boxes are fixedly installed at both ends of the discharge box. A threaded rod is movably installed on the inner wall of the discharge box. Screw rods are fixedly installed on both sides of the threaded rods. The screw rods pass through the drive boxes. It is worth noting that the multiple filter layers should have the basic solid filtration function of filtering certain impurities, debris, etc.
[0008] As a further improvement of this utility model: a discharge port is provided on one side of the inner wall of the filter box, the filter plate is inclined, and one side of the filter plate is in contact with the discharge port.
[0009] As a further embodiment of this utility model: a sealing cover is movably provided at the top of the filter box, a water pump is fixedly provided at the top of the sealing cover, and the bottom end of the water pump passes through the sealing cover and is fixed thereon.
[0010] As a further embodiment of this utility model: the water tank is a shell with an open top, the water tank is parallel to the filter plate, the bottom of the inner wall of the water tank is inclined, a drive motor is fixedly installed at the bottom of the filter box, the top of the drive motor passes through the water tank and is fixedly installed with a stirring rod, a number of conductive plates are fixedly installed on the surface of the stirring rod, and a number of conductive sheets are fixedly installed on the surface of the conductive plates.
[0011] As a further improvement of this utility model: the bottom of the inner wall of the water tank is provided with several water outlets, and the bottom of the filter box is fixedly provided with a connection port, and the water outlets are connected to the connection port.
[0012] As a further improvement of this utility model: the bottom of the inner wall of the water tank is provided with several water outlets, and the bottom of the filter box is fixedly provided with a connection port, and the water outlets are connected to the connection port.
[0013] As a further embodiment of this utility model: a driving component is fixedly provided on the inner wall of the drive box, the driving component is fitted with a screw rod and threadedly connected, the driving component drives the screw rod to rotate, the rotation direction of the driving component is kept synchronous, and a waste port is opened at the bottom of one side of the discharge box.
[0014] Compared with the prior art, the present invention provides a filtration device for demineralized water treatment, which has the following beneficial effects:
[0015] This invention uses an inclined filter layer for initial filtration. The liquid penetrates the filter layer and flows down to the top of the permeation membrane. Under the influence of gravity, it rolls and filters out colloids and large organic molecules. After the liquid enters the water tank, the drive motor rotates the stirring rod. Electrodialysis is performed on the filtered water using conductive sheets. The demineralized water that has been stirred and filtered is then discharged through the outlet and connected to the connection port for further processing.
[0016] In this invention, impurities that fail to pass through the filter layer slide onto the threaded rod through the discharge port. At this time, the drive box and drive components drive the screw rod to rotate, causing the threaded rod to rotate. During the rotation, the filtered impurities continuously rotate and move inside the threaded plates on the surface of the threaded rod. During the movement of the impurities, some of them fall through the waste chute on one side of the discharge chute to the inner wall of the discharge box, making it convenient for staff to clean and avoiding the accumulation of impurities during long-term use, which would affect the cleaning process.

[0025] Example: A filtration device for demineralized water treatment, such as Figures 1-4As shown, the system includes a filter box 1, a filter plate 2 fixedly installed on one side of the inner wall of the filter box 1, a permeation membrane 3 fixedly installed on the top of the filter plate 2, and multiple filter layers 4 fixedly installed on the top of the permeation membrane 3. A discharge box 5 is fixedly installed on one side of the filter box 1, a water tank 6 is fixedly installed at the bottom of the inner wall of the filter box 1, and drive boxes 7 are fixedly installed at both ends of the discharge box 5. A threaded rod 8 is movably installed on the inner wall of the discharge box 5, and screw rods 9 are fixedly installed on both sides of the threaded rod 8. The screw rods 9 pass through the drive box 7. A discharge port 10 is opened on one side of the inner wall of the filter box 1. The filter plate 2 is inclined and one side of the filter plate 2 is in contact with the discharge port 10. Impurities that have not passed through the filter layers 4 slide onto the threaded rod 8 through the discharge port 10, avoiding the need to maintain the mechanical parts used for cleaning during mechanical cleaning, reducing operation steps, and eliminating the need to replace the filter layers and clean the threaded rods periodically.
[0026] like Figures 1-3 As shown, a sealing cover 11 is movably installed at the top of the filter box 1. A water pump 12 is fixedly installed at the top of the sealing cover 11. The bottom end of the water pump 12 passes through the sealing cover 11 and is fixed thereon. The water tank 6 is a shell with an open top. The water tank 6 is parallel to the filter plate 2. The bottom end of the inner wall of the water tank 6 is inclined. A drive motor 13 is fixedly installed at the bottom of the filter box 1. A stirring rod 14 is fixedly installed at the top of the drive motor 13, passing through the water tank 6. Several conductive plates 15 are fixedly installed on the surface of the stirring rod 14. Several conductive sheets 16 are fixedly installed on the surface of the conductive plates 15. The water tank 6... The bottom of the inner wall of the filter box 1 is provided with several outlets 17. The bottom of the filter box 1 is fixedly provided with a connection port 18. The outlets 17 are connected to the connection port 18. The liquid undergoes primary filtration through the inclined filter layer 4. The liquid penetrates the filter layer 4 and flows down to the top of the permeation membrane 3. Under the inclined gravity, the liquid rolls and filters colloids and large molecular organic matter. After the liquid enters the water tank 6, the drive motor 13 drives the stirring rod 14 to rotate. The filtered water is electrodialyzed with the help of the conductive sheet 16. The demineralized water that has been stirred and filtered goes through the outlet 17 and then through the connection port 18 for the next step.
[0027] like Figures 1-2 As shown, a discharge trough 19 is provided on the inner wall of the discharge box 5. Several waste troughs 20 are provided on one side of the discharge trough 19.

The driving component 21 drives the threaded rod 8 to rotate. The rotation direction of the driving component 21 is kept synchronous. A waste port 22 is provided at the bottom of one side of the discharge box 5. The drive box 7 and the driving component 21 drive the screw rod 9 to rotate, causing the threaded rod 8 to rotate. During the rotation process, some impurities fall through the waste troughs 20 on one side of the discharge trough 19 to the inner wall of the discharge box 5, thus avoiding the accumulation of impurities.
[0028] Working principle: The liquid undergoes initial filtration through the inclined filter layer 4, flowing down to the top of the permeation membrane 3. Under the influence of gravity, it rolls and filters colloids and large organic molecules. After entering the water tank 6, the drive motor 13 drives the stirring rod 14 to rotate. Electrodialysis is performed on the filtered water with the help of the conductive sheet 16. The demineralized water filtered by the stirring passes through the outlet 17 and the connection port 18 for the next step. Impurities that do not pass through the filter layer 4 slide onto the threaded rod 8 through the discharge port 10. At this time, the drive box 7 and the drive component 21 drive the screw rod 9 to rotate, causing the threaded rod 8 to rotate. During the rotation, the filtered impurities continuously rotate and move inside the threaded plate on the surface of the threaded rod 8. During the movement, some impurities fall through the waste trough 20 on one side of the discharge trough 19 to the inner wall of the discharge box 5, which is convenient for the staff to clean and avoids the accumulation of impurities during long-term use, which would affect the staff's cleaning.
