Description

Technical Field

[0001] This utility model belongs to the field of dissolving kettle filtration technology, and specifically relates to a filtration device for a dissolving kettle. Background Technology

[0002] A dissolving vessel is a device used in chemical reactions or the dissolution of substances, typically consisting of a sealed container. When dissolving silica sol, a specialized dissolving vessel is required, and to ensure the dissolved silica sol solution is usable directly, it is usually equipped with a dedicated filtration system.

[0003] Existing dissolving tank filtration devices often leave undissolved large particles in the liquid after processing raw materials. Traditional filtration methods typically involve directly installing a filter screen at the drain outlet, but this simple approach easily leads to filter clogging, requiring frequent manual cleaning. This not only reduces production efficiency but also affects the stability and reliability of the filtration effect. Utility Model Content

[0004] In view of this, the present invention provides a filtration device for a dissolving vessel, which can achieve automated filtration and cleaning functions through the coordinated operation of the filtration mechanism and the cleaning component, thereby improving production efficiency, reducing manual intervention, and ensuring the stability and reliability of the filtration effect.

[0005] To solve the above-mentioned technical problems, this utility model provides a filtration device for a dissolving vessel, including a dissolving vessel and a stirring frame rotatably connected to its upper end, and a filtration mechanism disposed at the lower end of the inner cavity of the dissolving vessel. The filtration mechanism is characterized in that it is used to filter the silica sol solution in the dissolving vessel. The filtration mechanism includes a sliding frame slidably connected to the lower end of the inner cavity of the dissolving vessel, an annular filter screen is provided inside the sliding frame, a circular opening is provided at the lowest end of the sliding frame, and a cleaning component for sealing the circular opening is also provided inside the sliding frame. A driving component for driving the sliding frame to move up and down is also provided at the lower end of the dissolving vessel, which facilitates subsequent cleaning, prevents filter screen clogging, realizes automated filtration and cleaning functions, improves production efficiency, reduces manual intervention, and ensures the stability and reliability of the filtration effect.

[0006] The axial cross-section of the slip ring filter is V-shaped, which can guide the trapped impurities and make them gather at the cone part.

[0007] The cleaning assembly includes a fixed plate disposed within the inner cavity of the sliding frame. A rotating rod is rotatably connected to the middle of the fixed plate, and a sliding rod is slidably connected to the middle of the rotating rod. The sliding rod is located directly below the stirring frame. A sealing plate is provided at the lower end of the sliding rod. The axial cross-section of the sealing plate is inverted V-shaped and is configured to fit with a circular opening. Multiple support rods are provided on the inner arc surface of the lower end drain pipe of the dissolving vessel. All support rods are in contact with the sealing plate. The lower end of the rotating rod is also provided with a cleaning component for cleaning the filter surface of the annular filter screen, which serves to open and close the circular opening.

[0008] The cleaning component includes multiple scrapers located at the lower end of the outer arc surface of the rotating rod. The scrapers are in contact with the inclined surface of the filter screen, thus scraping away the impurities that remain on the filter screen surface.

[0009] The driving components are multiple electric telescopic rods located at the lower end of the dissolving vessel. The telescopic ends of the multiple electric telescopic rods pass through the corresponding sealing sliding holes at the lower end of the dissolving vessel and are fixedly connected to the sliding frame, thereby driving the sliding frame and its auxiliary mechanisms to move up or down.

[0010] It also includes a reset assembly, which is used to reset the sealing plate. The reset assembly includes an assembly cavity located in the middle of the rotating rod. The upper end of the outer arc surface of the sliding rod inside the assembly cavity is provided with an annular plate. A spring is provided between the annular plate and the assembly cavity. The spring is movably sleeved on the outside of the sliding rod, which plays the role of automatic reset.

[0011] It also includes a transmission assembly, which transmits the rotational force of the stirring frame to the rotating rod. The transmission assembly is located at the upper end of the rotating rod with crown tooth one, and the lower end of the stirring frame is provided with crown tooth two. Crown tooth two engages with crown tooth one, thus playing the role of transmission.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. The stirring rack stirs the silica sol solution. After dissolution, it is discharged from the dissolution vessel. During the discharge process, impurities in the silica sol are intercepted by the annular filter screen, thereby achieving the filtration of the silica sol. The annular filter screen is generally inverted cone shape, which can guide the retained impurities and make them gather at the cone part, which is convenient for subsequent cleaning.

[0014] 2. After the solution is completely drained, the telescopic end of the electric telescopic rod extends, thereby pushing the sliding frame and its auxiliary mechanisms upward. At this time, the sliding rod will first contact the lower end of the stirring frame. As the sliding frame and its auxiliary mechanisms continue to move upward, the sliding rod and the sealing plate will compress the spring through the annular plate, thereby driving the sealing plate away from the circular opening. Finally, the second crown tooth will engage with the first crown tooth, and then drive the stirring frame to rotate. The second crown tooth and the first crown tooth will drive the rotating rod and multiple scrapers to rotate. When the multiple scrapers rotate, they will scrape off the impurities stuck on the filter surface of the annular filter screen. The impurities will flow into the drain pipe at the lower end of the dissolving vessel through the circular opening and be discharged. This can clean the filter screen, prevent clogging, realize automated filtration and cleaning functions, improve production efficiency, reduce manual intervention, and ensure the stability and reliability of the filtration effect.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] This embodiment provides a filtration device for a dissolving vessel, such as... Figure 1-4The image shows a dissolving vessel 100 and a stirring frame 200 rotatably connected to its upper end. It also includes a filtration mechanism located at the lower end of the inner cavity of the dissolving vessel 100. The filtration mechanism is used to filter the silica sol solution within the dissolving vessel 100. The filtration mechanism includes a sliding frame 300 slidably connected to the lower end of the inner cavity of the dissolving vessel 100. The sliding frame 300 contains an annular filter screen 301. The lowest end of the sliding frame 300 has a circular opening. The sliding frame 300 also contains a cleaning component for sealing the circular opening. The lower end of the dissolving vessel 100 also has a driving component for driving the sliding frame 300 to move up and down.

[0022] The stirring rack 200 stirs the silica sol solution. After dissolution, it is discharged from the dissolving vessel 100. During the discharge process, impurities in the silica sol are intercepted by the annular filter screen 301, thereby achieving the filtration of the silica sol. After the solution is completely discharged, the driving component pushes the sliding rack 300 and its auxiliary mechanism to move upward, opening the circular opening. Finally, the filter screen can be cleaned by adding external cleaning fluid and cleaning components to prevent clogging. This realizes automated filtration and cleaning functions, improves production efficiency, reduces manual intervention, and ensures the stability and reliability of the filtration effect.

[0023] like Figure 2-4 As shown, the axial cross-section of the sliding ring filter 301 is V-shaped, and its overall shape is an inverted cone, which can guide the retained impurities and make them gather at the cone.

[0024] like Figure 2-4 As shown, the cleaning assembly includes a fixed plate 400 disposed in the inner cavity of the sliding frame 300. A rotating rod 401 is rotatably connected to the middle of the fixed plate 400, and a sliding rod 402 is slidably connected to the middle of the rotating rod 401. The sliding rod 402 is located directly below the stirring frame 200. A sealing plate 403 is provided at the lower end of the sliding rod 402. The axial cross-section of the sealing plate 403 is inverted V-shaped and is configured to cooperate with a circular opening. Multiple support rods 404 are provided on the inner arc surface of the lower end drain pipe of the dissolving vessel 100. All multiple support rods 404 are in contact with the sealing plate 403. The lower end of the rotating rod 401 is also provided with a cleaning component for cleaning the filter surface of the annular filter screen 301.

[0025] When cleaning is required, the sliding rod 402 and the sealing plate 403 move down, thereby causing the sealing plate 403 to move away from the circular opening, ultimately opening the circular opening. After cleaning is completed, the sliding rod 402 and the sealing plate 403 reset and reseal the circular opening, thus playing the role of opening and closing the circular opening.

[0026] like Figure 2-4As shown, the cleaning component includes multiple scrapers 700 disposed at the lower end of the outer arc surface of the rotating rod 401. The scrapers 700 are all in contact with the inclined surface of the filter screen 301 and are used to scrape off the impurities that remain on the filter surface of the filter screen 301.

[0027] like Figure 1-4 As shown, multiple electric telescopic rods 500 are installed at the lower end of the dissolving vessel 100. The telescopic ends of the multiple electric telescopic rods 500 pass through the corresponding sealing sliding holes at the lower end of the dissolving vessel 100 and are fixedly connected to the sliding frame 300. When the telescopic ends of the electric telescopic rods 500 extend or retract, they drive the sliding frame 300 and its auxiliary mechanisms to move up or down.

[0028] like Figure 3-4 As shown, a reset assembly is included. The reset assembly is used to reset the sealing plate 403. The reset assembly includes an assembly cavity 600 located in the middle of the rotating rod 401. The upper end of the outer arc surface of the sliding rod 402 located inside the assembly cavity 600 is provided with an annular plate 601. A spring 602 is provided between the annular plate 601 and the assembly cavity 600. The spring 602 is movably sleeved on the outside of the sliding rod 402.

[0029] When cleaning is required, the sliding rod 402 will contact the lower end of the stirring frame 200. As the sliding frame 300 and its auxiliary mechanisms continue to move upward, the sliding rod 402 and the sealing plate 403 will compress the spring 602 through the annular plate 601, thereby driving the sealing plate 403 away from the circular opening, and finally opening the circular opening. After cleaning is completed, all mechanisms will reset. Under the action of the spring 602's rebound force, the sliding rod 402 and the sealing plate 403 will reset and reseal the circular opening, thus achieving the function of automatic reset.

[0030] like Figure 2-4 As shown, it also includes a transmission assembly, which is used to transmit the rotational force of the stirring frame 200 to the rotating rod 401. The transmission assembly is provided at the upper end of the rotating rod 401 with crown tooth 800, and the lower end of the stirring frame 200 is provided with crown tooth 801. Crown tooth 801 and crown tooth 800 are in active engagement.

[0031] When crown tooth 2 801 and crown tooth 1 800 are engaged, the rotational force of the stirring frame 200 can be transmitted to the rotating rod 401, so that the rotating rod 401 and its auxiliary mechanism rotate synchronously. When the two are separated, the rotating rod 401 is not driven.

[0032] The working principle of the filtration device for the dissolving vessel provided by this utility model is as follows: The stirring rack 200 stirs the silica sol solution. After dissolution, it is discharged from the dissolving vessel 100. During the discharge process, impurities in the silica sol are intercepted by the annular filter screen 301, thereby achieving the filtration of the silica sol. After the solution is completely discharged, the telescopic end of the electric telescopic rod 500 extends, thereby pushing the sliding rack 300 and its auxiliary mechanism to move upward. At this time, the sliding rod 402 will first contact the lower end of the stirring rack 200. As the sliding rack 300 and its auxiliary mechanism continue to move upward, the sliding rod 402 and the sealing plate 403 compress the spring 602 through the annular plate 601, thereby driving the sealing plate 403 to move upward. 03 After leaving the circular opening, the second crown tooth 801 engages with the first crown tooth 800, driving the stirring frame 200 to rotate. The second crown tooth 801 and the first crown tooth 800 drive the rotating rod 401 and multiple scrapers 700 to rotate. As the scrapers 700 rotate, they scrape off the impurities stuck on the filter surface of the annular filter screen 301. The impurities flow through the circular opening into the drain pipe at the lower end of the dissolving vessel 100 and are eventually discharged. This process cleans the filter screen, prevents clogging, and achieves automated filtration and cleaning functions. It improves production efficiency, reduces manual intervention, and ensures the stability and reliability of the filtration effect. After cleaning, all mechanisms reset and reseal the circular opening.

[0033] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
