Description

Technical Field

[0001] This utility model relates to cleaning agents, and in particular to a filtration device for a rust-proof and corrosion-resistant metal cleaning agent. Background Technology

[0002] Rust and corrosion resistant metal cleaners are chemical agents specifically designed to clean metal surfaces while preventing rust and corrosion. These cleaners not only effectively remove dirt, grease, oxides, and other impurities from metal surfaces, but also form a protective film that slows down or prevents contact between the metal and moisture, oxygen, and other corrosive substances in the air, thus achieving rust and corrosion prevention.

[0003] During the production of rust-proof and corrosion-resistant metal cleaners, some solid impurities are generated. In order to ensure the purity of the cleaner's components, the solution needs to be filtered after the cleaner reaction. After filtration, some solution will remain in the filtration equipment along with the filter residue, thereby reducing the yield of the rust-proof and corrosion-resistant metal cleaner.

[0004] To address the above issues, we propose a filtration device for rust- and corrosion-resistant metal cleaning agents. Utility Model Content

[0010] A further feature of this invention is that the elastic telescopic mechanism includes a plurality of springs;

[0011] The upper end of the filter frame is provided with several telescopic grooves, and the spring is connected between the bottom wall of the telescopic groove and the filter frame on the upper side.

[0012] A stop rod is fixedly connected to the lower end of the filter frame, and the spring is sleeved on the stop rod.

[0013] A further feature of this invention is that a rubber pad is fixedly connected to the upper end of the abutment rod.

[0014] A further feature of this invention is that a top-layer filter frame is slidably connected to the inner curved surface of the filter cavity, the filter membrane is fixedly connected to the top-layer filter frame, and the intermediate filter frame is slidably connected between the top-layer filter frame and the bottom-layer filter frame.

[0015] A further feature of this invention is that a plurality of sliding grooves are provided on the inner curved surface of the filter cavity, and a plurality of sliders are fixedly connected to the outer curved surfaces of the top filter frame, the middle filter frame and the bottom filter frame, and the sliders are slidably connected in the sliding grooves.

[0016] A further feature of this invention is that the driving mechanism includes a plurality of cylinders;

[0017] The cylinder is fixedly installed on the filter cylinder. A horizontal plate is fixedly connected to the end of the piston rod of the cylinder, and a push rod is fixedly connected to the lower end. The end of the push rod extends into the filter chamber, and the lower end of the push rod is fixedly connected to the upper end of the top layer filter frame.

[0018] A further feature of this invention is that a vacuum pump is installed on the discharge pipe.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] The top filter frame drives several intermediate filter frames to move downwards in stages, and in the process of moving downwards, it squeezes the filter residue on the filter membrane, thereby squeezing out the filtrate remaining in the filter residue to improve the reaction yield.

[0021] After the filter residue is squeezed, the elastic telescopic mechanism can drive the intermediate filter frames to return to their original position, so that the intermediate filter frames maintain an appropriate distance between them, so that the raw liquid can pass through for layer-by-layer filtration.

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 3 As shown, a filtration device for a rust-proof and corrosion-resistant metal cleaner includes a filter cylinder 11, with an upward-facing filter chamber 12 inside the filter cylinder 11. A sealing cap 13 is fixedly connected to the upper end of the filter cylinder 11, and a feeding pipe 14 communicating with the filter chamber 12 is fixedly connected to the sealing cap 13. Unfiltered raw liquid enters the filter chamber 12 through the feeding pipe 14. A discharge pipe 17 is fixedly connected to the bottom of the filter chamber 12, and a vacuum pump 29 is installed on the discharge pipe 17. During filtration, the vacuum pump 29 creates a pressure difference between the filter chamber 12 and the outside atmosphere to improve filtration efficiency.

[0030] A filter frame assembly 15 is provided on the inner curved surface of the filter cavity 12. The filter frame assembly 15 is specifically connected as follows: the filter frame 15 includes a plurality of intermediate filter frames 23 and a bottom filter frame 24. Filter membranes 16 are installed on the intermediate filter frames 23 and the bottom filter frames 24. A top filter frame 22, which is also provided with the filter membranes 16, is slidably connected up and down on the inner curved surface of the filter cavity 12. The bottom filter frame 24 is fixedly connected to the inner curved surface of the filter cavity 12. The intermediate filter frames 23 are slidably connected between the top filter frame 22 and the bottom filter frame 24.

[0031] In addition, several grooves 25 are provided on the inner curved surface of the filter cavity 12. Several sliders 26 are fixedly connected to the outer curved surfaces of the top filter frame 22, the middle filter frame 23 and the bottom filter frame 24. The sliders 26 are slidably connected in the grooves 25. Through the above structure, the connection stability between the top filter frame 22, the middle filter frame 23 and the bottom filter frame 24 and the filter cavity 12 is enhanced, thereby ensuring that the three can move up and down smoothly in the filter cavity 12.

[0032] The sealing cover is equipped with a driving mechanism for driving the intermediate filter frame 23 to move up and down relative to the bottom filter frame 24. After filtration is completed, the driving mechanism drives the top filter frame 22 to press the intermediate filter frame 23 downward, so that each intermediate filter frame 23 moves downward step by step, and squeezes the filter residue on the filter membrane 16 during the step-by-step movement, thereby squeezing out the residual filtrate in the filter residue and improving the reaction yield.

[0033] The specific structure of the driving mechanism is as follows: the driving mechanism includes a plurality of cylinders 27, the cylinders 27 are fixedly installed on the filter cylinder 11, the piston rod end of the cylinder 27 is fixedly connected to a horizontal plate 31, the lower end of the 31 is fixedly connected to a push rod 28, the end of the push rod 28 extends into the filter chamber 12, and the lower end of the push rod 28 is fixedly connected to the upper end of the top layer filter frame 22. Through the above mechanism, the top layer filter frame 22 is driven to press the middle filter frame 23 downward, thereby squeezing out the residual filtrate in the filter residue.

[0034] An elastic telescopic mechanism is provided between the top filter frame 22 and the middle filter frame 23, between the middle filter frame 23 and the bottom filter frame 24, and between each of the middle filter frames 23. After the filtrate remaining in the filter residue is squeezed out, the middle filter frame 23 is reset by the elastic telescopic mechanism.

[0035] The specific structure of the elastic telescopic mechanism is as follows: the elastic telescopic mechanism includes a plurality of springs 18, and the upper ends of the intermediate filter frame 23 and the bottom filter frame 24 are provided with a plurality of telescopic grooves 19. The springs 18 are connected between the bottom wall of the telescopic groove 19 and the upper intermediate filter frame 23 or the top filter frame 22. The lower ends of the top filter frame 22 and the intermediate filter frame 23 are fixedly connected with a stop rod 20, and the springs 18 are sleeved on the stop rod 20.

[0036] It should be noted here that, as Figure 2 As shown, after the original solution is filtered, the filter residue on the filter membrane 16 is thick. With a relatively thick filter cake, the filter frame assembly 15 compresses the filter residue on the filter membrane 16. .

[0037] When the filter residue is squeezed, the top filter frame 22 moves upward until the filter residue on the top filter frame 22 comes into contact with the sealing cover 13, and the filter residue on the top filter frame 22 is continuously squeezed to squeeze out the filtrate remaining in the filter residue.

[0038] Subsequently, the top filter frame 22 moves downward. When the abutment 20 on the top filter frame 22 is inserted into the telescopic groove 19, the top filter frame 22 drives the intermediate filter frame 23 below to move downward synchronously, and so on, thereby driving each intermediate filter frame 23 to move downward step by step, and squeezing the filter residue during the downward movement, thereby squeezing out the residual filtrate in the filter residue.

[0039] After the extrusion is complete, the top filter frame 22 and the intermediate filter frame 23 move upward step by step under the drive of the cylinder 27, and the intermediate filter frame 23 is reset under the action of the spring 18, so that the distance between each intermediate filter frame 23 is reset to the distance before extrusion.

[0040] Furthermore, a rubber pad 21 is fixedly connected to the upper end of the abutment rod 20, thereby buffering the impact force generated when the abutment rod 20 is inserted into the telescopic groove 19, so as to protect the intermediate filter frame 23 and the bottom filter frame 24.

[0041] The filter cartridge 11 is provided with a movable door 30, which technicians can open periodically to clean the filter residue on the filter membrane 16.

[0042] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
