Description

Technical Field

[0001] This invention relates to the field of activated carbon processing technology, specifically to a processing equipment for modified activated carbon. Background Technology

[0002] In the field of activated carbon modification and processing, there are some prominent problems in the traditional processing equipment that uses impregnation to process activated carbon.

[0003] On the one hand, during the mixing process of the modified liquid and activated carbon, the presence of air in the processing tank affects the full contact and uniform mixing of the modified liquid and activated carbon, resulting in poor modification effect and inconsistent quality of the modified activated carbon, making it difficult to meet the production requirements of high-quality activated carbon products.

[0004] On the other hand, the existing stirring devices have a relatively simple and fixed structure and a limited stirring range. The stirring of activated carbon and modification liquid in different positions in the processing tank is insufficient and uneven, which makes it impossible for some activated carbon to be effectively modified, reducing the efficiency of the entire processing process and the quality of the products. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a processing device for modified activated carbon.

[0006] To achieve the above objectives, this application provides the following technical solution: a processing device for modified activated carbon, comprising a processing tank with a lid on top, and a processing mechanism disposed on the lid and capable of being inserted into the processing tank to modify activated carbon. The lid and the processing tank are sealed together. The processing mechanism includes a sealing plate disposed below the lid, a lifting assembly disposed on the lid and connected to the sealing plate, an exhaust assembly disposed on the sealing plate, and a stirring assembly disposed inside the processing tank to mix and stir the modified liquid and activated carbon. When modifying the activated carbon, the lifting assembly drives the sealing plate to move towards the surface of the modified liquid inside the processing tank, cooperating with the exhaust assembly to expel air between the sealing plate and the liquid surface, and closing the exhaust assembly when the modified liquid enters the exhaust assembly. The stirring assembly stirs the modified liquid and activated carbon.

[0007] Preferably, the exhaust assembly includes an exhaust column vertically disposed at the top of the sealing disc with an exhaust port opening, a slide rod vertically disposed within the exhaust chamber, a floating sealing block slidably passing through the exhaust chamber and movably fitted onto the slide rod, and multiple sealing blocks disposed on the side of the floating sealing block and slidingly sealingly against the inner wall of the exhaust chamber. When the floating sealing block moves to the top position of the exhaust chamber, the multiple sealing blocks seal and fit together with the connection holes on the side of the exhaust column. The density of the floating sealing block is less than the density of the modified liquid. An exhaust chamber is provided inside the exhaust column, and the exhaust chamber communicates with the exhaust port through a connection hole at the bottom of the exhaust column.

[0008] Preferably, the lifting assembly includes a sealing screw that passes through the can lid axially, and a lifting component disposed on the can lid and controlling the lifting movement of the sealing screw. The sealing screw has a limiting groove along its length, and a limiting block is slidably disposed in the limiting groove. The limiting block is disposed on the can lid.

[0009] Preferably, the lifting component includes a driven gear that is threadedly connected to the sealing screw rod and a drive gear that is mounted on the can lid, driven by a sealing motor and meshing with the driven gear. The driven gear is rotatably mounted on the top of the can lid.

[0010] Preferably, the stirring assembly includes a plurality of telescopic members arranged sequentially from top to bottom along the axial direction, a mixing rod disposed at the same end of each telescopic member, and a drive structure disposed at the bottom of the processing tank and driving the plurality of telescopic members to rotate.

[0011] Preferably, the telescopic component includes an extension arm with a telescopic groove at the top, an extension rod movably inserted into the telescopic groove at the bottom, a telescopic spring inserted into the telescopic groove and connected at both ends to the bottom wall of the telescopic groove and the end of the extension rod, and a positioning strip fixedly disposed axially on the extension rod, the positioning strip being movably inserted into the positioning groove opened in the wall of the telescopic groove; when the telescopic spring is in its normal extended state, one end of the extension rod inserted into the telescopic groove is located at the opening of the telescopic groove; a hybrid rod is provided on the side of the extension rod away from the extension arm.

[0012] Preferably, the stirring assembly further includes a second connecting block fixedly disposed on the top of the uppermost extension rod, and a first connecting block disposed on the bottom end face of the sealing plate, wherein the first connecting block and the connecting groove opened on the top of the second connecting block are matched.

[0013] The beneficial effects of this invention are as follows: By setting a unique venting component, when the lifting component moves the sealing disc towards the surface of the modified liquid, the air between the sealing disc and the liquid surface can be smoothly discharged. When the modified liquid enters the venting component, the venting component automatically closes, preventing air from mixing in again. This allows the modified liquid and activated carbon to fully contact and mix in a near-air-free environment, improving the modification effect of the activated carbon, ensuring the stability and consistency of the modification quality, and enabling the production of high-quality modified activated carbon products. The addition of a stirring component to mix the modified liquid and activated carbon ensures thorough and uniform processing of the activated carbon. Attached Figure Description

[0021] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0022] Example 1: Reference Figures 1-5 The illustrated processing equipment for modified activated carbon includes a processing tank 1 with a lid 2 on top, and a processing mechanism disposed on the lid 2 and inserted into the processing tank 1 to modify activated carbon. The lid 2 and the processing tank 1 are sealed together. The processing mechanism includes a sealing plate 8 disposed below the lid 2, a lifting assembly disposed on the lid 2 and connected to the sealing plate 8, an exhaust assembly disposed on the sealing plate 8, and a stirring assembly disposed inside the processing tank 1 to mix and stir the modified liquid and activated carbon. When modifying the activated carbon, the lifting assembly moves the sealing plate 8 towards the surface of the modified liquid inside the processing tank 1, and cooperates with the exhaust assembly to expel the air between the sealing plate 8 and the liquid surface. The exhaust assembly is closed when the modified liquid enters the exhaust assembly, and the stirring assembly stirs the modified liquid and activated carbon.

[0023] In this embodiment, the modified liquid and activated carbon are placed in the processing tank 1, and then the tank cover 2 is sealed and installed on the processing tank 1. At this time, the sealing plate 8 is moved vertically by the lifting component. When the sealing plate 8 moves downward into the processing tank 1, the side of the sealing plate 8 slides and seals against the inner wall of the processing tank 1, ensuring a relatively sealed space between the surface of the modified liquid and the sealing plate 8. As the sealing plate 8 approaches the surface of the modified liquid, the air in the sealed space is discharged to the top of the sealing plate 8 through the exhaust component on the sealing plate 8. When the bottom end face of the sealing plate 8 is in contact with the surface of the modified liquid, the modified liquid enters the exhaust component, and the exhaust component is closed. This creates a relatively airless environment, which facilitates the processing of activated carbon and modified liquid, improves the modification effect of activated carbon, ensures the stability and consistency of the modification quality, and enables the production of high-quality modified activated carbon products. The mixing component is used to mix and stir the modified liquid and activated carbon, ensuring that the activated carbon is fully and uniformly processed and improving the efficiency and effect of activated carbon modification.

[0024] It is understandable that the air between the sealing disc 8 and the modified liquid surface can be controlled to pass through the sealing disc 8 in various ways. This embodiment provides the following solution:

[0025] like Figure 2 and Figure 3 As shown, the exhaust assembly includes an exhaust column 9 vertically positioned at the top of the sealing disc 8 with an exhaust hole 13 opening, a slide rod 17 vertically positioned within the exhaust chamber 14, a floating sealing block 15 slidably passing through the exhaust chamber 14 and movably fitted onto the slide rod 17, and multiple sealing blocks 16 disposed on the side of the floating sealing block 15 and slidingly sealingly against the inner wall of the exhaust chamber 14. When the floating sealing block 15 moves to the top position of the exhaust chamber 14, the multiple sealing blocks 16 correspond one-to-one with the connecting holes 18 on the side of the exhaust column 9 and seal against each other. The density of the floating sealing block 15 is less than the density of the modified liquid. An exhaust chamber 14 is provided inside the exhaust column 9, and the exhaust chamber 14 communicates with the exhaust hole 13 through the connecting hole at the bottom of the exhaust column 9.

[0026] In this embodiment, when the lifting assembly moves the sealing disc 8 downward, the pressure inside the sealed space increases, pushing the floating sealing block 15 located on the exhaust port 13 upward. The airflow passes between the exhaust port 13 and the floating sealing block 15, sequentially through the exhaust chamber 14 connecting hole 18, and is discharged above the sealing disc 8. When the bottom of the sealing disc 8 is in contact with the surface of the modified liquid, the modified liquid enters the exhaust chamber 14 through the exhaust port 13. The floating sealing block 15 moves upward under the buoyancy of the modified liquid. When it moves to the top position, the multiple sealing blocks 16 provided on the side of the floating sealing block 15 are sealed and fitted into the opening of the connecting hole 18, thereby facilitating the processing of the modified liquid and activated carbon after the air between the sealing disc 8 and the modified liquid is vented.

[0027] It is understandable that the lifting and lowering movement of the sealing disc 8 can be achieved in various ways. This embodiment provides the following solution:

[0028] like Figure 1 and Figure 2 As shown, the lifting assembly includes a sealing screw 6 that passes through the can cover 2 axially, and a lifting component that is set on the can cover 2 and controls the sealing screw 6 to move up and down. The sealing screw 6 has a limiting groove 7 along its length, and a limiting block is slidably set in the limiting groove 7. The limiting block is set on the can cover 2.

[0029] In this embodiment, the sealing screw 6 is sleeved on the limiting block through the limiting groove 7, so that the sealing screw 6 can only move up and down along the length direction on the can cover 2. With the lifting component, the sealing disc 8 can be easily controlled to move up and down in the processing tank 1 through the sealing screw 6.

[0030] like Figure 2 As shown, the lifting component includes a driven gear 5 threadedly connected to the sealing screw 6 and a drive gear 4 mounted on the can lid 2, driven by a sealing motor 3 and meshing with the driven gear 5. The driven gear 5 is rotatably mounted on the top of the can lid 2. The sealing motor 3 drives the drive gear 4 to rotate, and the meshing action between the drive gear 4 and the driven gear 5 drives the driven gear 5 to rotate. The driven gear 5 is threadedly connected to the sealing screw 6, so the rotation of the driven gear 5 can be controlled to adjust the movement of the sealing screw 6 upward or downward along its length.

[0031] Example 2: Regarding the stirring component in Example 1, this example provides the following solution.

[0032] like Figure 2 and Figure 4 As shown, the stirring assembly includes multiple telescopic components arranged sequentially from top to bottom along the axial direction, a mixing rod 23 disposed on the same end of each telescopic component, and a drive structure disposed at the bottom of the processing tank 1 and driving the multiple telescopic components to rotate.

[0033] In this embodiment, the driving structure drives multiple telescopic components to rotate, which in turn allows the modified liquid and activated carbon in the processing tank 1 to be mixed and stirred by the mixing rod 23 set on the telescopic components.

[0034] like Figure 5As shown, the telescopic component includes an extension arm 19 with a telescopic groove 20 at the top, an extension rod 22 movably inserted into the telescopic groove 20 at the bottom, a telescopic spring 24 inserted into the telescopic groove 20 and connected at both ends to the bottom wall of the telescopic groove 20 and the end of the extension rod 22, respectively, and a positioning strip fixedly installed on the extension rod 22 along the axial direction. The positioning strip movably inserts into the positioning groove 21 opened in the groove wall of the telescopic groove 20. When the telescopic spring 24 is in the normal extended state, one end of the extension rod 22 inserted into the telescopic groove 20 is located at the opening of the telescopic groove 20. A hybrid rod 23 is provided on the side of the extension rod 22 away from the extension arm 19.

[0035] In this embodiment, one end of the mixing rod 23 of each set of extension rods 22 extends out of the telescopic groove 20. When the sealing plate 8 moves downward in the processing tank 1 and presses down on the end of the uppermost extension rod 22, multiple extension rods 22 move into the telescopic groove 20 simultaneously, compressing multiple telescopic springs 24 synchronously. Since the elastic force of multiple telescopic springs 24 is consistent, the spacing between adjacent mixing rods 23 is consistent, ensuring the uniformity of mixing the mixture of modified liquid and activated carbon at different depths. This facilitates thorough and uniform mixing of activated carbon and modified liquid at different positions in the processing tank 1, enabling effective modification treatment of activated carbon and improving the efficiency and product quality of the entire processing process.

[0036] Example 3: Regarding how to ensure the stability of the stirring component rotation in Example 2, this example provides the following solution.

[0037] like Figures 2-4 As shown, the stirring assembly also includes a second connecting block 11 fixedly mounted on the top of the uppermost extension rod 22, and a first connecting block 10 rotatably mounted on the bottom end face of the sealing plate 8. The first connecting block 10 matches the connecting groove 12 opened on the top of the second connecting block 11.

[0038] In this embodiment, when the sealing disc 8 moves downward, the first connecting block 10 passes through the connecting groove 12 opened in the second connecting block 11 at the top of the uppermost extension rod 22, and the first connecting block 10 is rotatably connected to the bottom of the sealing disc 8. The driving structure adopts a motor, which is located below the processing tank 1, and its output end is connected to the bottom of the lowermost extension arm 19. The motor can drive multiple extension arms 19, extension rods 22 and mixing rods 23 set on extension rods 22 to rotate, ensuring that multiple mixing rods 23 rotate stably, which is convenient for modifying the modified liquid and activated carbon.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
