Description

Technical Field

[0001] This utility model relates to the field of activated carbon screening technology, and in particular to a multi-layer screening device for activated carbon processing. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials are heated in the absence of air to reduce non-carbon components, and then react with gases. The surface is eroded, creating a structure with well-developed micropores. Because the activation process is a microscopic process, the surface erosion of a large number of molecular carbides is point erosion, resulting in countless tiny pores on the surface of activated carbon. During the production of activated carbon, it is necessary to screen activated carbon of different sizes.

[0003] Chinese patent discloses a multi-layer screening device for activated carbon processing (authorization announcement number CN216679029U). This patented technology uses a perforated plate frame and a sliding assembly. When the motor works, the output end of the motor drives the rotating shaft and the convex plate to rotate. Since the connecting plate, the convex plate, and the fixed seat are all rotatably connected by pins, and the perforated plate frame and the box are slidably connected by a sliding plate and a sliding groove, the perforated plate frame can slide horizontally left and right. This allows the activated carbon in the perforated plate frame to be fed evenly, which can avoid the phenomenon of large accumulation of activated carbon on the screen. This makes it easier for the activated carbon to pass through the screen and also avoids damage to the screen.

[0004] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing multi-layer screening devices for activated carbon processing screen activated carbon of different sizes through multiple layers of sieve plates. Since the activated carbon moves on the sieve plates, the activated carbon that rolls off the sieve plates is easily dispersed and is not easy to collect. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the activated carbon rolling off the sieve plate is easy to disperse and is not easy to collect because the activated carbon moves on the sieve plate. To this end, we propose a multi-layer sieving device for activated carbon processing.

[0006] To achieve the above objectives, this application adopts the following technical solution: a multi-layer screening device for activated carbon processing, comprising a feeding hopper, side plates fixedly connected to both sides of the feeding hopper, a placement plate fixedly connected to the inner side of the side plate, a plurality of sieve plates fixedly connected to the inner side of the side plate, a plurality of sieve holes opened at the top of the sieve plates, the sieve holes gradually decreasing in size from top to bottom, a plurality of collection slots opened on one side of the side plate, a plurality of collection boxes slidably connected inside the collection slots, the number of collection boxes corresponding to the number of sieve plates, a first placement slot opened on one side of the collection box, a through slot opened at the top inside the first placement slot, a limiting slot opened at the top inside the collection slot, a limiting plate slidably connected inside the limiting slot, a connecting plate fixedly connected to one end of the limiting plate, the surface of the connecting plate slidably connected to the inside of the first placement slot, an elliptical block rotatably connected inside the first placement slot, a connecting rod fixedly connected to one side of the elliptical block, and a knob installed at the other end of the connecting rod.

[0007] Preferably, the difference between the maximum and minimum diameters of the elliptical block is greater than the distance the limiting plate is inserted into the limiting groove.

[0008] Preferably, two thrust springs are fixedly connected to the top of the connecting plate, and the other end of the thrust springs is fixedly connected to the top of the first placement groove.

[0009] Preferably, an extension rod is slidably connected inside the connecting rod, and the other end of the extension rod is fixedly connected to one side of the knob. A limit hole is opened on one side of the collection box, and a limit block is fixedly connected to one side of the knob.

[0010] Preferably, the top and bottom of the connecting rod are provided with limiting grooves, and the top and bottom of the extension rod are fixedly connected with limiting sliders.

[0011] Preferably, one end of the extension rod is fixedly connected to a tension spring, and the other end of the tension spring is fixedly connected to one side of the inside of the connecting rod.

[0012] Preferably, the bottom of the collection box has four second placement slots, and pulleys are installed inside the second placement slots.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] In this invention, the user places the activated carbon to be screened into the hopper. The activated carbon rolls down through a groove on one side of the hopper onto a sieve plate inside the side plate. After being screened, activated carbon larger than the sieve holes rolls down the sieve plate into a collection box inside the placement plate for collection. When it is necessary to remove the activated carbon collected in the collection box, the user rotates a knob to rotate an elliptical block, releasing the limiting plate. The connecting plate moves downward under the influence of gravity, causing the limiting plate to disengage from the limiting groove, allowing the collection box to be removed for centralized processing of the screened activated carbon.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a multi-layer screening device for activated carbon processing, including a feeding hopper 1, side plates 2 fixedly connected to both sides of the feeding hopper 1, a placement plate 3 fixedly connected to the inner side of the side plate 2, and several screen plates 4 fixedly connected to the inner side of the side plate 2. Several screen holes 22 are opened at the top of the screen plates 4, with the screen holes 22 gradually decreasing in size from top to bottom. Several collection grooves 23 are opened on one side of the side plate 2, and several collection boxes 5 are slidably connected inside the collection grooves 23. The number of collection boxes 5 corresponds to the number of screen plates 4. A first placement groove 6 is opened on one side of the collection box 5, and a through groove 7 is opened at the top inside the first placement groove 6. A limiting groove 8 is opened at the top inside the collection groove 23, and a limiting plate 9 is slidably connected inside the limiting groove 8. A connecting plate 10 is fixedly connected to one end of the limiting plate 9, and the surface of the connecting plate 10 is slidably connected to the inside of the first placement groove 6. An elliptical block 11 is rotatably connected inside the placement trough 6. A connecting rod 12 is fixedly connected to one side of the elliptical block 11, and a knob 13 is installed at the other end of the connecting rod 12. The difference between the maximum and minimum diameters of the elliptical block 11 is greater than the distance that the limiting plate 9 is inserted into the limiting groove 8. The user puts the activated carbon to be screened into the inside of the feeding hopper 1. It rolls down through the groove on one side of the feeding hopper 1 onto the sieve plate 4 inside the side plate 2. After being screened by the sieve plate 4, activated carbon with a volume larger than the sieve hole 22 rolls down the sieve plate 4 into the collection box 5 inside the placement plate 3 for collection. When it is necessary to remove the activated carbon collected in the collection box 5, the elliptical block 11 is rotated by rotating the knob 13, which releases the limiting of the connecting plate 10. The connecting plate 10 moves downward under the influence of gravity, causing the limiting plate 9 to disengage from the inside of the limiting groove 8, so that the collection box 5 can be removed, which facilitates the centralized processing of the screened activated carbon.

[0023] Reference Figure 4 As shown in this embodiment: two thrust springs 14 are fixedly connected to the top of the connecting plate 10. The other end of the thrust spring 14 is fixedly connected to the top of the first placement slot 6. When the user needs to take out the activated carbon inside the collection box 5, the knob 13 is rotated to drive the elliptical block 11 to rotate, thereby releasing the restriction on the connecting plate 10. The thrust spring 14 pushes the connecting plate 10 to move downward, thereby releasing the restriction on the collection box 5. By installing the thrust spring 14, the connecting plate 10 can be prevented from getting stuck and unable to fall.

[0024] Reference Figure 5As shown in this embodiment: an extension rod 15 is slidably connected inside the connecting rod 12, and the other end of the extension rod 15 is fixedly connected to one side of the knob 13. A limiting hole 16 is opened on one side of the collection box 5, and a limiting block 17 is fixedly connected to one side of the knob 13. When the user needs to remove the activated carbon inside the collection box 5, he / she pulls the knob 13 to disengage the limiting block 17 from the inside of the limiting hole 16, so that the knob 13 can rotate and release the limitation on the collection box 5. The limiting hole 16 and the limiting block 17 limit the knob 13 to prevent the knob 13 from rotating due to the thrust of the thrust spring 14.

[0025] Reference Figure 5 As shown in this embodiment: the top and bottom of the connecting rod 12 are provided with limiting grooves 18, and the top and bottom of the extension rod 15 are fixedly connected with limiting sliders 19. When the user pulls the knob 13, the limiting sliders 19 at the top and bottom of the extension rod 15 move inside the limiting grooves 18 to restrict the movement of the extension rod 15 and prevent the extension rod 15 from leaving the interior of the connecting rod 12.

[0026] Reference Figure 5 As shown in this embodiment: one end of the extension rod 15 is fixedly connected to a tension spring 20, and the other end of the tension spring 20 is fixedly connected to one side of the inside of the connecting rod 12. By installing a tension spring 20 at one end of the extension rod 15, a continuous tension can be released on the extension rod 15 to prevent the knob 13 from being displaced by vibration, causing the limiting block 17 to disengage from the inside of the limiting hole 16.

[0027] Reference Figure 3 As shown in this embodiment: the bottom of the collection box 5 is provided with four second placement slots 21, and the inside of the second placement slots 21 is equipped with pulleys 24. By installing pulleys 24 at the bottom of the collection box 5, the pushing and pulling of the collection box 5 can be made smoother, and the wear of the bottom of the collection box 5 can be reduced.

[0028] Working principle: The user puts the activated carbon to be screened into the feeding hopper 1. It rolls down through a groove on one side of the feeding hopper 1 onto the sieve plate 4 inside the side plate 2. After being screened by the sieve plate 4, activated carbon with a volume larger than the sieve holes 22 rolls down the sieve plate 4 into the collection box 5 inside the placement plate 3 for collection. When it is necessary to remove the activated carbon collected in the collection box 5, the knob 13 is rotated to drive the elliptical block 11 to rotate, releasing the limiting position on the connecting plate 10. The connecting plate 10 moves downward under the influence of gravity, causing the limiting plate 9 to disengage from the limiting groove 8, allowing the collection box 5 to be removed for centralized processing of the screened activated carbon. When it is necessary to remove the activated carbon from the collection box 5, the knob 13 is rotated to drive the elliptical block 11 to rotate, releasing the limiting position on the connecting plate 10. The thrust spring 14 pushes the connecting plate 10 downward, releasing the limiting position on the collection box 5. The installation of the thrust spring 14 can prevent the connecting plate 10 from being locked. When the collection box 5 is stuck and cannot fall, and the activated carbon inside needs to be removed, pull the knob 13 to disengage the limiting block 17 from the limiting hole 16, allowing the knob 13 to rotate and release the limitation on the collection box 5. The limiting hole 16 and the limiting block 17 limit the knob 13 to prevent it from being affected by the pushing force of the push spring 14. During the pulling of the knob 13, the limiting sliders 19 at the top and bottom of the extension rod 15 move inside the limiting groove 18 to restrict the movement of the extension rod 15 and prevent the extension rod 15 from disengaging from the connecting rod 12. By installing a tension spring 20 at one end of the extension rod 15, a continuous tension can be released on the extension rod 15 to prevent the knob 13 from being displaced by vibration, causing the limiting block 17 to disengage from the limiting hole 16. By installing a pulley 24 at the bottom of the collection box 5, the pushing and pulling of the collection box 5 can be made smoother, while reducing the wear on the bottom of the collection box 5.
