Description

Technical Field

[0001] This utility model relates to the field of polyurethane flexible foam silicone oil preparation technology, and in particular to a secondary filtration and feeding system device for polyurethane flexible foam silicone oil preparation. Background Technology

[0002] Polyurethane flexible foam silicone oil is a widely used chemical additive in the production of polyurethane flexible foam (sponge), primarily acting as a foam stabilizer. During the production process of polyurethane foam, polyurethane flexible foam silicone oil effectively stabilizes the cell structure, preventing bubble aggregation and breakage, thus resulting in a uniform and fine foam. Different types of polyurethane flexible foam silicone oil have different processing tolerances, enabling them to adapt to the production of polyurethane foams with varying densities and process requirements.

[0003] During the preparation of polyurethane flexible foam silicone oil, secondary filtration is required. The polyurethane flexible foam silicone oil is filtered through the filter screen of the secondary filtration box. Although the existing secondary filtration box can conveniently and effectively filter polyurethane flexible foam silicone oil, a large amount of impurities adhere to the filter screen after filtration. Since the filter screen is located inside the secondary filtration box, it is inconvenient to remove the filter screen for cleaning. Therefore, a secondary filtration feeding system device for the preparation of polyurethane flexible foam silicone oil is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing filter screen is located inside the secondary filter box, which makes it inconvenient to remove and clean the filter screen. Therefore, this invention proposes a secondary filtration feeding system for the preparation of polyurethane flexible foam silicone oil.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A secondary filtration and feeding system for preparing polyurethane flexible foam silicone oil includes a rectangular secondary filtration box. A first rectangular opening is provided on one side of the secondary filtration box. A support leg is fixedly connected to the bottom of the secondary filtration box. A first rectangular groove is provided at the first rectangular opening. A second rectangular groove is provided on the inner wall of the secondary filtration box. A rectangular plate is slidably connected within the first rectangular groove. A first handle is fixedly connected to one side of the rectangular plate. A filter screen is fixedly connected to one side of the rectangular plate, located within the first rectangular opening. A connecting plate is fixedly connected to one side of the filter screen. The connecting plate is slidably connected to the second rectangular groove. A limiting groove is provided on the secondary filtration box. A limiting hole is provided on the connecting plate. A limiting plate is slidably connected within the limiting groove, and the limiting plate is slidably connected to the limiting hole.

[0007] Preferably, a second rectangular opening is provided on one side of the secondary filter box, and a rectangular block is fixedly connected to one side of the limiting plate, with the rectangular plate slidably connected to the second rectangular opening.

[0009] Preferably, a secondary feeding pipe is fixedly connected to one side of the secondary filter box, and a discharge pipe is fixedly connected to one side of the secondary filter box, with an electromagnetic valve installed on the discharge pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. When using this equipment, the limiting plate can be removed from the limiting groove by the rectangular block, and then the first handle can be pulled to slide the rectangular plate from the first rectangular groove. The rectangular plate will then pull the filter screen out from the first rectangular opening, which will make it easy to remove the filter screen from the inside of the secondary filter box for cleaning.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1-Figure 5 A secondary filtration and feeding system for preparing polyurethane flexible foam silicone oil includes a rectangular secondary filtration box 1, a first rectangular opening 2 on one side of the secondary filtration box 1, and a support leg fixedly connected to the bottom of the secondary filtration box 1.

[0021] Furthermore, a first rectangular groove 3 is provided at the first rectangular opening 2, and a second rectangular groove 4 is provided on the inner wall of the secondary filter box 1. A rectangular plate 5 is slidably connected in the first rectangular groove 3. A first handle 6 is fixedly connected to one side of the rectangular plate 5. A filter screen 7 is fixedly connected to one side of the rectangular plate 5. The filter screen 7 is located in the first rectangular opening 2. A connecting plate 8 is fixedly connected to one side of the filter screen 7. The connecting plate 8 is slidably connected to the second rectangular groove 4.

[0022] The polyurethane flexible foam silicone oil is filtered twice through two filter screens 7 to improve the filtration effect on impurities.

[0023] Specifically, by pulling the first handle 6, the rectangular plate 5 is moved to slide out of the first rectangular groove 3, and the rectangular plate 5 moves the filter screen 7 out of the first rectangular opening 2.

[0024] Furthermore, a limiting groove 9 is provided on the secondary filter box 1, and a limiting hole 10 is provided on the connecting plate 8. A limiting plate 11 is slidably connected in the limiting groove 9, and the limiting plate 11 is slidably connected to the limiting hole 10.

[0025] When the secondary filter box 1 is in use, the limiting plate 11 in the limiting groove 9 limits the connecting plate 8, thereby limiting the filter screen 7 and preventing the filter screen 7 from sliding out of the first rectangular opening 2 during the filtration process. If you want to take out the filter screen 7 for cleaning, you need to take the limiting plate 11 out of the limiting groove 9 first.

[0026] Furthermore, a second rectangular opening 12 is provided on one side of the secondary filter box 1, and a rectangular block 13 is fixedly connected to one side of the limiting plate 11. The rectangular plate 5 is slidably connected to the second rectangular opening 12.

[0027] The rectangular block 13 facilitates the removal of the limiting plate 11 from the limiting groove 9.

[0028] Furthermore, a top cover 14 is slidably connected to the top of the secondary filter box 1, a sealing plate 15 is fixedly connected to the bottom of the top cover 14, the sealing plate 15 is slidably connected to the inner wall of the secondary filter box 1, and a second handle 16 is fixedly connected to the top of the top cover 14.

[0029] The top cover 14 and the sealing plate 15 seal the secondary filter box 1. When it is necessary to remove the filter screen 7 for cleaning, the top cover 14 is opened and the limiting plate 11 is removed so that the filter screen 7 can be removed for cleaning. At the same time, opening the top cover 14 can also clean the inner wall of the secondary filter box 1.

[0030] Furthermore, a secondary feeding pipe is fixedly connected to one side of the secondary filter box 1, and a discharge pipe 17 is fixedly connected to one side of the secondary filter box 1. An electromagnetic valve 18 is installed on the discharge pipe 17.

[0031] The process involves feeding polyurethane flexible foam silicone oil into the secondary filter box 1 through a secondary feeding pipe, and discharging the filtered polyurethane flexible foam silicone oil through the discharge pipe 17. The discharge of polyurethane flexible foam silicone oil is controlled by a solenoid valve 18.

[0032] The working principle of this utility model:

[0033] When it is necessary to remove the filter screen 7 for cleaning, the limiting plate 11 is removed from the limiting groove 9 by the rectangular block 13, and then the first handle 6 is pulled to drive the rectangular plate 5 to slide from the first rectangular groove 3. The rectangular plate 5 drives the filter screen 7 to be removed from the first rectangular opening 2, so that the filter screen 7 can be removed from the inside of the secondary filter box 1 for cleaning, which is quite convenient.

[0034] The polyurethane flexible foam silicone oil is fed into the secondary filter box 1 through the secondary feeding pipe. After filtration, the polyurethane flexible foam silicone oil is discharged through the discharge pipe 17. The discharge of polyurethane flexible foam silicone oil is controlled by the solenoid valve 18.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
