Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon screening devices, in particular to an activated carbon screening device for an activation furnace. Background Technique

[0002] Activated carbon is an excellent adsorbent that has been used earlier and has a wide range of applications. It is made by carbonizing various carbon-containing substances such as coal, resin, wood chips, fruit shells, fruit cores, bamboo slices, coconut shell slices, palm shells, etc., and then activating them with steam or chemical agents. During the processing of activated carbon, it needs to be heated and activated in an activation furnace, and the activation furnace has certain size limitations on the materials, so it is necessary to screen the activated carbon materials first.

[0003] For example, an activated carbon screening device for an activation furnace disclosed in Chinese Patent Publication No. CN220781200U outputs through a third discharge port. The pore diameters of the first and second mesh holes can be set to sizes that meet the feeding requirements of the activation furnace, so that the activated carbon with sizes within the pore diameters of the first and second mesh plates is output through the second discharge port to meet the use of the activation furnace. Through the above technical solution, it is possible to facilitate the rapid screening of activated carbon that meets the size requirements. The two sieves are arranged up and down and screened synchronously, reducing the size of the device and improving the screening efficiency.

[0004] For example, in the above screening device, synchronous screening is completed by arranging two sieves up and down. Generally speaking, double screening is achieved. The first mesh hole intercepts large particles, and the second mesh hole intercepts smaller particle impurities than the first mesh hole; however, due to the overall design of the first and second mesh plates, when cleaning the impurities in the mesh holes after screening, it is necessary to disassemble and assemble the two mesh plates, and then cooperate with a vibration motor and a reciprocating brush to complete the cleaning of the mesh holes and the collection of impurities, and the operation is relatively complicated. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides an activated carbon screening device for an activation furnace, which solves the problems put forward in the above background technique.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: An activated carbon screening device for an activation furnace includes a screening box, a compartment for accommodating activated carbon is opened inside the screening box, the screening box is detachably connected to a top cover for opening the compartment through a threaded groove provided at the top, and the top cover is limit-mounted inside the screening module;

[0007] The screening module comprises a centrifugal screen cylinder with a double-layer interior installed under the top cover, and a positioning piece for positioning is detachably connected to the top of the top cover, a screening tube penetrating the top cover and passing into the interior of the centrifugal screen cylinder is arranged in the middle of the positioning piece, and filter screens with selectable apertures are arranged on both layers inside the centrifugal screen cylinder; the outer layer and the inner layer of the centrifugal screen cylinder cooperate with the closed bottom to form a small particle interception and placement area, and the inner layer and the bottom of the centrifugal screen cylinder form a large particle interception and placement area, so that subsequent classification and centralized collection are more convenient, and double screening is completed by the double-layer setting of the centrifugal screen cylinder; preferably, the positioning piece ensures that the screening tube is stably inserted and rotated in the screening box and the centrifugal screen cylinder;

[0008] A further improvement of the technical solution of the utility model is that a plurality of discharge ports for activated carbon are provided at the bottom of the screening tube, the screening tube is keyed to bevel gear 1 at a position above the centrifugal screen cylinder, and one side of the bevel gear 1 is meshed with bevel gear 2 which is keyed to the drive shaft.

[0009] A further improvement of the technical solution of the utility model is that: a feed pipe connected to a solid delivery pump is rotated through the top of the screening tube, and a plurality of centrifugal rods are welded to the screening tube at the axis of the centrifugal screen cylinder; in order to ensure that the activated carbon is centrifugally thrown in the centrifugal screen cylinder and passes through the filter screen, after the driving shaft completes the rotation of the bevel gear two, the bevel gear one finally completes the rotation of the screening tube. At this time, the activated carbon infused into the screening tube by the solid delivery pump is centrifugally thrown in the centrifugal screen cylinder due to the self-rotation of the screening tube and the centrifugation of the centrifugal rods, thereby realizing the initial screening.

[0010] A further improvement of the technical solution of the utility model is that: the driving shaft is connected to the driving motor through a coupling, and the other output end of the driving motor is connected to the re-screening module;

[0011] The re-screening module consists of a linkage shaft connected to the other output end of the driving motor through a coupling, a vibration shaft located on both sides below the screening box, pulleys on the linkage shaft and the vibration shaft, and belts sleeved on the pulleys.

[0012] A further improvement of the technical solution of the utility model is that the cam mechanism can be detachably connected to the vibration shaft, and the cam mechanism contacts the guide unloading screen plate welded to the inner wall of the screening box, and the guide unloading screen plate is provided with a screen with controllable aperture.

[0013] A further improvement of the technical solution of the utility model is that a feeding pipe located between two groups of guiding feeding screen plates is arranged at the bottom of the screening box.

And the double-layer setting of the centrifugal sieve cylinder completes double screening, and with the rotation of the sieve pipe and the centrifugation of the centrifugal rod, the activated carbon is centrifugally thrown in the centrifugal sieve cylinder to achieve primary screening.

[0017] 2. The activated carbon screening device of this activation furnace rotates the vibration shaft through the pulley and the belt in the re-screening module. The vibration shaft rotates in the screening box, and the cam mechanism completes the vibration of the guiding blanking sieve plate, thus avoiding the blockage of the sieve mesh and achieving three screenings.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] Referring to Figures 1 - 4 , the present invention provides three technical solutions:

[0030] Embodiment 1:

[0031] An activated carbon screening device for an activation furnace, including a screening box 1. An accommodation compartment for accommodating activated carbon is provided inside the screening box 1. The screening box 1 is detachably connected to a top cover 101a for opening the compartment through a threaded groove provided at the top. The top cover 101a is limit-mounted in the screening module;

[0032] The screening module includes a double-layer centrifugal sieve tube 201 provided below the top cover 101a. A positioning member 201a for positioning is detachably connected to the top of the top cover 101a. A sieve tube 201b passing through the top cover 101a and leading into the inside of the centrifugal sieve tube 201 is provided in the middle of the positioning member 201a. Filter meshes 201c with selectable pore sizes are provided on both layers inside the centrifugal sieve tube 201;

[0033] In this embodiment, as can be seen from the above, the bottom of the outer layer and the inner layer of the centrifugal sieve tube 201 cooperate to form a small particle interception and placement area, and the inner layer and the bottom of the centrifugal sieve tube 201 form a large particle interception and placement area. Therefore, subsequent classified centralized collection is more convenient, and double screening is completed by the double-layer setting of the centrifugal sieve tube 201;

[0034] Preferably, the positioning member 201a ensures that the sieve tube 201b is stably inserted and rotates in the screening box 1 and the centrifugal sieve tube 201;

[0035] And this embodiment provides a relatively common disassembly, assembly and collection method. Since the top cover 101a is connected to the screening box 1 through a threaded groove, when disassembling and assembling, the top cover 101a is manually rotated, and the top cover 101a and the double-layer centrifugal sieve tube 201 are taken out of the screening box 1 as a whole. Then, the top cover 101a and the centrifugal sieve tube 201 are separated. Finally, the centrifugal sieve tube 201 is tilted to take out the intercepted impurities inside.

[0036] Embodiment 2:

[0037] On the basis of Example 1: a plurality of discharge ports 201b-1 for discharged activated carbon are opened at the bottom of the screening tube 201b, the screening tube 201b is keyed to a bevel gear 1 201b-2 at the position above the centrifugal screen cylinder 201, and a bevel gear 2 201b-4 keyed to a drive shaft 201b-3 is meshed with one side of the bevel gear 1 201b-2.

[0038] The top of the screening tube 201b is rotated to pass through a feed pipe 201b-6 connected to a solid delivery pump 201b-5, and the screening tube 201b is located at the inner axis of the centrifugal screen cylinder 201 and a plurality of centrifugal rods 201b-7 are welded.

[0039] In this embodiment, based on the first embodiment, in order to ensure that the activated carbon is centrifugally thrown in the centrifugal screen drum 201 and passes through the set filter screen 201c, the driving shaft 201b-3 completes the rotation of the bevel gear 2 201b-4, and finally the bevel gear 1 201b-2 completes the rotation of the screening tube 201b. At this time, the solid conveying pump 201b-5 infuses the activated carbon into the screening tube 201b. Due to the rotation of the screening tube 201b and the centrifugal operation of the centrifugal rod 201b-7, the activated carbon is centrifugally thrown in the centrifugal screen drum 201, thereby achieving initial screening.

[0040] Embodiment three:

[0041] On the basis of the first and second embodiments: the driving shaft 201b-3 is connected to the driving motor 201b-8 through a coupling, and the other output end of the driving motor 201b-8 is connected to the re-screening module;

[0042] The re-screening module consists of a linkage shaft 301 connected to the other output end of the driving motor 201b-8 through a coupling, a vibration shaft 301-1 located on both sides below the screening box 1, pulleys 301-2 located on the linkage shaft 301 and the vibration shaft 301-1, and a belt 301-3 sleeved on each of the pulleys 301-2.

[0043] The vibration shaft 301-1 is detachably connected to a cam mechanism 301-1a, and the cam mechanism 301-1a contacts and welds a guide unloading screen plate 301-1b on the inner wall of the screening box 1, and a screen 301-1c with controllable aperture is provided on the guide unloading screen plate 301-1b.

[0044] In this embodiment, after the driving motor 201b-8 is driven on the basis of the second embodiment, the pulley 301-2 and the belt 301-3 complete the rotation of the vibration shaft 301-1. In this case, the vibration shaft 301-1 rotates in the screening box 1. At this time, the cam mechanism 301-1a completes the vibration of the guiding unloading screen plate 301-1b, thereby avoiding the blockage of the screen 301-1c and realizing three screenings.

[0045] A discharge pipe 302 is provided at the bottom of the screening box 1 and is located between two groups of guiding discharge sieve plates 301-1b.

[0046] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0047] During use, after the overall device is installed, start the drive motor 201b-8 and the solid conveying pump 201b-5. After the drive shaft 201b-3 completes the rotation of the bevel gear 201b-4, finally the bevel gear 201b-2 completes the rotation of the sieve pipe 201b. At this time, the activated carbon infused into the sieve pipe 201b by the solid conveying pump 201b-5 is thrown out of the centrifugal sieve drum 201 due to the self-rotation of the sieve pipe 201b and the centrifugal force of the centrifugal rod 201b-7, and passes through the guiding discharge sieve plate 301-1b. At this time, the pulley 301-2 and the belt 301-3 complete the rotation of the vibration shaft 301-1. In this case, the vibration shaft 301-1 rotates inside the screening box 1, and at this time, the cam mechanism 301-1a completes the vibration of the guiding discharge sieve plate 301-1b. After screening, take out the top cover 101a and the double-layer centrifugal sieve drum 201 as a whole from the screening box 1, then separate the top cover 101a and the centrifugal sieve drum 201, and finally pour the centrifugal sieve drum 201 to take out the intercepted impurities inside.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
