[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0023] To address the problems of existing dispersant dilution filtration devices, such as the single filtration method, difficulty in cleaning the internal filtration structure, and impact on continuous operation, please refer to [the relevant documentation / reference]. Figures 1-4 This embodiment provides the following technical solution:

[0024] This embodiment of a dispersant multi-stage dilution and filtration device includes a device housing 1, which is divided into upper and lower parts. A movable maintenance ring 3 is provided between the upper and lower parts of the device housing 1. One end of the device housing 1 is embedded in the movable maintenance ring 3 and is sealed to the movable maintenance ring 3. An upper filter frame 4 is installed in the middle of the inside of the device housing 1. The upper filter frame 4 is fixed in the middle of the device housing 1 and abuts against the movable maintenance ring 3. A bottom filter plate 105 is installed at the lower end of the inside of the device housing 1. After the dispersant is mixed and diluted, it is filtered through the bottom filter plate 105 to improve the product quality of the dispersant.

[0025] The movable maintenance ring 3 has connecting plates 301 welded to both sides. A hydraulic cylinder 302 is installed at the lower end of the connecting plate 301. The hydraulic cylinder 302 is fixedly connected to the connecting plate 301 and the ground. The movable maintenance ring 3 is lifted by the hydraulic cylinder 302. The movable maintenance ring 3 rises and opens the middle of the device housing 1, so that the surface of the upper filter frame 4 can be cleaned. The structure is stable, improves filtration, and is easy to clean, so as to adapt to continuous operation.

[0026] It should be noted that the lower end of the mobile maintenance ring 3 is provided with an integrally formed sliding groove 303. The upper part of the device housing 1 is slidably connected to the mobile maintenance ring 3 through the sliding groove 303. The mobile maintenance ring 3 is sealed with a sealing gasket 305. The lower part of the device housing 1 is sealed to the mobile maintenance ring 3 through the sealing gasket 305. The sliding groove 303 keeps the position stable, and the sealing effect is maintained by the sealing gasket 305 and the positioning groove 304.

[0027] In addition, six support frames 402 are installed inside the upper filter frame 4, and oblique filter screens 401 are fixedly installed between the six support frames 402. When the dispersant multi-stage dilution filtration device is working, the dispersant is filtered through the upper filter frame 4 before dilution, and is filtered through the filter screens 401. A bearing sleeve 403 is installed in the middle of the upper filter frame 4, and the rotating shaft 102 passes through the bearing sleeve 403 and is rotatably connected to the upper filter frame 4.

[0028] Specifically, in operation, the dispersant multi-stage dilution and filtration device filters the dispersant through the upper filter frame 4 for upper-stage filtration before dilution, and through the filter screen 401. After dilution, it passes through the bottom filter plate 105 for lower-stage filtration, improving the product quality of the dispersant. After multi-stage filtration, the moving inspection ring 3 is lifted by the hydraulic cylinder 302. The rising of the moving inspection ring 3 opens the middle of the device housing 1, allowing the surface of the upper filter frame 4 to be cleaned. The structure is stable, improves filtration, and is easy to clean, making it suitable for continuous operation.

[0029] To address the issue of poor dilution and filtration efficiency in existing dispersant dilution and filtration devices during practical use, thus affecting product quality, please refer to... Figures 1-4 This embodiment provides the following technical solution:

[0030] In this embodiment, support legs 101 are fixedly installed at the lower end and both sides of the device housing 1. The support legs 101 are connected to the device housing 1 by fixing bolts. The support legs 101 support the upper and lower parts of the device housing 1, which facilitates the adjustment of the upper filter frame 4.

[0031] The device housing 1 has a rotating shaft 102 at its center. A magnetic stirring paddle 103 is installed at the lower end of the rotating shaft 102, and a limit bearing 106 is installed at the upper end of the rotating shaft 102. The rotating shaft 102 is rotatably connected to the device housing 1 through the limit bearing 106. The rotating shaft 102 drives the magnetic stirring paddle 103 to rotate, and the magnetic stirring paddle 103 dilutes the diluent and dispersant at the bottom of the device housing 1.

[0032] In fact, an electromagnetic base 104 is provided at the lower end of the device housing 1. The electromagnetic base 104 is embedded inside the device housing 1 and fixedly connected to the device housing 1. The magnetic stirring paddle 103 is set as a magnetic rod structure wrapped with polytetrafluoroethylene. By turning on the power of the electromagnetic base 104, the magnetic stirring paddle 103 placed on the electromagnetic base 104 is used to rotate in a circle using the principle of like poles repelling and unlike poles attracting in magnetic fields, thereby achieving the purpose of stirring the dispersant and diluent and realizing the effect of mixing and dilution.

[0033] In addition, an opening is provided in the center of the electromagnetic base 104, and the bottom filter plate 105 is inserted into the opening and fixedly connected to the electromagnetic base 104 and the device housing 1. A valve body is provided at the lower end of the device housing 1, and the diluted dispersant is discharged out of the opening by opening the valve body.

[0034] Furthermore, a sealing cover plate 2 is installed at the upper end of the device housing 1 to seal the device housing 1. The sealing cover plate 2 is connected to the device housing 1 by a flange seal, and an integrally formed feed port 201 is provided between the sealing cover plate 2 and the device housing 1 to introduce dispersant and diluent.

[0035] Specifically, the dispersant and diluent are introduced through the feed inlet 201, the power of the electromagnetic base 104 is turned on, and the magnetic stirring paddle 103 placed on the electromagnetic base 104 is rotated in a circular motion to stir the dispersant and diluent, thereby achieving the effect of mixing and dilution. After dilution, the diluted dispersant is discharged through the outlet by opening the valve body.

[0036] Working principle: During use, the dispersant and diluent are introduced through the feed inlet 201. Before dilution, the dispersant undergoes upper-level filtration through the upper filter frame 4 and filter screen 401. After dilution, it undergoes lower-level filtration through the bottom filter plate 105, improving the product quality of the dispersant. The electromagnetic base 104 is powered on, and the magnetic stirring paddle 103 placed on the electromagnetic base 104 rotates in a circular motion, utilizing the principle of like poles repelling and unlike poles attracting, thereby achieving the purpose of stirring the dispersant and diluent and realizing the effect of mixing and dilution. It then undergoes lower-level filtration through the bottom filter plate 105, improving the product quality of the dispersant. After multi-stage filtration, the moving inspection ring 3 is lifted by the hydraulic cylinder 302. The moving inspection ring 3 rises, opening the middle of the device housing 1, allowing for cleaning of the surface of the upper filter frame 4. The structure is stable, improving filtration while facilitating cleaning, and is suitable for continuous operation. After dilution, the diluted dispersant is discharged through the outlet by opening the valve body.
