Description

Technical Field

[0001] This utility model belongs to the technical field of carbon black production equipment, specifically relating to an air-cooled carbon black cooler. Background Technology

[0002] In the carbon black production process, carbon black cooling is a crucial step. Air-cooled carbon black coolers, as commonly used cooling equipment, work by utilizing heat exchange between air and high-temperature carbon black to cool it down. For example, the existing patent with publication number CN202509025U discloses "a carbon black cooler comprising a frame, with an inclined guide plate inside the frame, a carbon black inlet at the upper part of the frame near the high end of the guide plate, a carbon black outlet at the bottom of the frame near the low end of the guide plate, an air inlet on one side of the frame and located behind the guide plate, and an air outlet on the other side of the frame, located in front of the guide plate." It can be seen that this application describes a common type of air-cooled carbon black cooler.

[0003] However, in the actual use of existing air-cooled carbon black coolers, when the air exchanges heat with the carbon black inside the cooler, it will carry some fine carbon black dust particles out of the air outlet. These carbon black dust particles will not only cause unnecessary losses, reduce the production and economic benefits of carbon black, but also cause certain pollution to the surrounding environment. Therefore, this utility model proposes an air-cooled carbon black cooler. Utility Model Content

[0004] The purpose of this invention is to provide an air-cooled carbon black cooler to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air-cooled carbon black cooler, comprising...

[0006] The main body includes a carbon black inlet located at the top of the main body, a carbon black outlet located at the bottom of the main body, an air inlet located on the left side of the main body, an air outlet located on the right side of the main body, a fan installed at the end of the air outlet, and a guide plate installed on the inner side of the main body, wherein the top of the guide plate is located at the bottom of the carbon black inlet, and the bottom of the guide plate is located at the top of the carbon black outlet.

[0007] It also includes a filter assembly, which includes a top plate and a metal filter fixed to the bottom surface of the top plate. The top surface of the main body has an opening corresponding to the metal filter. The metal filter passes through the opening to the inside of the main body and covers the inner end of the air outlet. The top plate presses against the top surface of the main body.

[0008] Preferably, the filter assembly further includes a brush removal structure disposed on the inner wall of the main body. The brush removal structure includes a support fixed to the inner wall of the main body and a movable rod that movably passes through the support. An arc-shaped movable block is fixed to the right end of the movable rod. The right side surface of the arc-shaped movable block is provided with multiple bristles, and the bristles are in contact with the metal filter. A spring is sleeved between the surface of the movable rod and the support and the arc-shaped movable block.

[0009] Preferably, an end plate is fixed to the left end surface of the movable rod relative to the left side of the support.

[0010] Preferably, the end plate slides in contact with the inner wall of the main body, and the arc-shaped movable block also slides in contact with the inner wall of the main body.

[0011] Preferably, the right end of the spring abuts against the left side surface of the arc-shaped movable block, and the left end of the spring abuts against the side of the support.

[0012] Preferably, the filter assembly further includes a fixing structure, which includes two threaded rods fixed to the top surface of the main body. Both sides of the top plate are provided with U-shaped notches corresponding to the threaded rods. The top end of the threaded rod passes through the U-shaped notches to the top of the top plate, and a wing nut is fitted on the top surface of the threaded rod. The wing nut presses the top plate tightly and fixes it.

[0013] Preferably, a rubber pad is embedded in the inner wall of the socket, and the side of the rubber pad is provided with an integral sealing protrusion that is in contact with the metal filter screen.

[0014] Preferably, two lifting blocks are symmetrically fixed to the top surface of the top plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model improves and optimizes the existing air-cooled carbon black cooler by designing a detachable filter screen at the air outlet. This filter screen can block some carbon black dust particles in the air when the air is discharged, and after the carbon black dust particles accumulate, they fall into the carbon black outlet by their own weight, thereby reducing unnecessary carbon black loss during air cooling. At the same time, the filter screen can be moved up and down periodically, causing the brushing structure on the inner wall to brush off the carbon black accumulated on the filter screen and also fall into the carbon black outlet. This effectively solves the problem of high carbon black loss in the existing air-cooled carbon black cooler, improves the cooling effect and service life of the cooler, and reduces equipment maintenance costs and environmental pollution.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 5 This is the first embodiment of the present invention, which provides a technical solution: an air-cooled carbon black cooler, comprising...

[0025] The structure comprises: a main body 1; a carbon black inlet 2 at the top of the main body 1; a carbon black outlet 3 at the bottom of the main body 1; an air inlet 4 on the left side of the main body 1; an air outlet 5 on the right side of the main body 1; a fan 7 installed at the end of the air outlet 5; and a guide plate 8 installed inside the main body 1. The top of the guide plate 8 is located at the bottom of the carbon black inlet 2, and the bottom of the guide plate 8 is located at the top of the carbon black outlet 3. This allows the carbon black entering from the carbon black inlet 2 to be discharged from the carbon black outlet 3 under the action of the guide plate 8. During this process, due to the operation of the fan 7, air enters from the air inlet 4 and is discharged from the air outlet 5, allowing the air to exchange heat with the carbon black and thus cool the carbon black. The above structures are all technologies that have been disclosed in the prior art. For details, please refer to the existing patent with publication number CN202509025U. Further details will not be provided here.

[0026] It also includes a filter assembly 6, which includes a top plate 61 and a metal filter 62 welded and fixed to the bottom surface of the top plate 61. The top surface of the main body 1 has an insertion port 11 corresponding to the metal filter 62. The metal filter 62 passes through the insertion port 11 to the inside of the main body 1 and covers the inner end of the air outlet 5. The top plate 61 presses against the top surface of the main body 1, so that when the air inside the main body 1 is discharged from the air outlet 5, it can filter out the fine carbon black dust particles carried in the air through the metal filter 62. The fine carbon black dust particles will be blocked by the metal filter 62 and, after accumulation, fall into the carbon black outlet 3 and be discharged under their own weight, thus avoiding unnecessary carbon black loss during the air heat exchange process. It is worth noting that in actual applications, the mesh size of the metal filter 62 can be selected according to different filtration requirements to ensure that the fine carbon black dust particles carried during the air heat exchange process can be filtered out smoothly.

[0027] In this embodiment, preferably, the filter assembly 6 further includes a brushing structure disposed on the inner wall of the main body 1. The brushing structure includes a support 651 welded and fixed to the inner wall of the main body 1, and a movable rod 652 that movably passes through the support 651. An arc-shaped movable block 654 is fixed to the right end of the movable rod 652. The right side surface of the arc-shaped movable block 654 is provided with multiple bristles 655, and the bristles 655 are in contact with the metal filter 62. A spring 653 is sleeved between the surface of the movable rod 652 and the support 651 and the arc-shaped movable block 654. Under the pushing force, the bristles 655 on the side of the arc-shaped movable block 654 maintain good contact with the metal filter screen 62. Subsequently, the operator can periodically move the top plate 61 up and down, causing the metal filter screen 62 to move up and down. When the metal filter screen 62 moves up and down, the bristles 655 will brush off the fine carbon black dust particles accumulated on the metal filter screen 62. The brushed-off fine carbon black dust particles will also fall into the carbon black outlet 3 for discharge, which not only facilitates the cleaning of the surface of the metal filter screen 62, but also allows the cleaned-off fine carbon black dust particles to be discharged normally.

[0028] In this embodiment, preferably, an end plate 656 is fixed to the left end surface of the movable rod 652 relative to the left side of the support 651, so that the movable rod 652 will not be directly separated from the support 651, thus playing a blocking role.

[0029] In this embodiment, preferably, the end plate 656 slides in contact with the inner wall of the main body 1, and the arc-shaped movable block 654 also slides in contact with the inner wall of the main body 1.

[0030] In this embodiment, preferably, the right end of the spring 653 abuts against the left side surface of the arc-shaped movable block 654, and the left end of the spring 653 abuts against the side of the support 651.

[0031] In this embodiment, preferably, the filter assembly 6 further includes a fixing structure, which includes two threaded rods 632 welded and fixed to the top surface of the main body 1. Both sides of the top plate 61 are provided with U-shaped notches 631 corresponding to the threaded rods 632. The top end of the threaded rod 632 passes through the U-shaped notches 631 to the top of the top plate 61, and a wing nut 633 is fitted on the top surface of the threaded rod 632. The wing nut 633 presses and fixes the top plate 61, so as to achieve stable fixation of the top plate 61 during daily use. When it is necessary to remove the top plate 61 or move it up and down in the future, simply rotate the wing nut 633 counterclockwise to unscrew it, release the fixation of the top plate 61, and the top plate 61 can be moved up and down directly.

[0032] In this embodiment, preferably, two lifting blocks are symmetrically welded and fixed to the top surface of the top plate 61 to facilitate subsequent lifting operations of the top plate 61 by operators.

[0033] Example 2

[0034] Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a rubber pad 111 is embedded in the inner wall of the socket 11, and the side of the rubber pad 111 is provided with an integral sealing protrusion 112 that is in contact with the metal filter screen 62, which can play an effective sealing role.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
