Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon binder processing, and more specifically to a drying device for processing activated carbon binder. Background Art

[0002] Activated carbon binders are mainly used to bond activated carbon particles into a shape. It is necessary to consider both the adhesion of the binder to the activated carbon and ensure that the microparticles in the binder do not block the pores of the activated carbon, which may affect subsequent use. Common binding materials include resins and the like.

[0003] Combined with the publication number CN216011548U, the publication date is March 11, 2022, which discloses a drying device for processing activated carbon binder.

[0004] In the prior art including the above patent, the utility model is provided with a rotating feeding rod, so that the rotating feeding rod can rotate through the driving motor to transfer the activated carbon binder at the bottom end of the drying cylinder to the top. By setting a centrifugal fan, the moisture in the drying cylinder can be sucked out through the centrifugal fan in a strongly humid climate, and when cooperating with the electric heating wire to dry the inside of the drying cylinder, the hot air generated by heating can be discharged, which further improves the drying effect. However, the electric heating wire heats the air, and the hot air mainly accumulates in the upper part of the drying cylinder, while the cold air and the air containing moisture are located in the lower part. The position of the desiccant packet is fixed. After long-term use, the water absorption conditions above and below the desiccant packet are different, affecting the overall water absorption efficiency. When replacing the desiccant packet, it is necessary to open the drying cylinder and then remove and replace it, which is rather troublesome. Summary of the Utility Model

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] As Figures 1-6 shown, a drying device for processing an activated carbon binder includes:

[0027] A horizontally arranged drying cylinder 1, on which a heating layer 4 for heating the drying cylinder 1 is provided;

[0028] A hollow rotating shaft 2 driven by a motor, on which a plurality of through holes 21 are opened, and the first end of the hollow rotating shaft 2 extends out of the drying cylinder 1 and is closed by a sealing cover 22;

[0029] A desiccant bag 7 is assembled in the hollow rotating shaft 2, and a plurality of sub-packaging bags 71 for accommodating desiccant are provided on the desiccant bag 7.

[0030] Specifically, a feed inlet and a discharge outlet are provided on the drying cylinder 1. The drying cylinder 1 is inclined in the horizontal direction, and the inclination angle is less than 8°. The desiccant bag 7 is a non-woven bag with good flexibility.

[0031] Furthermore, since the drying cylinder 1 is horizontally arranged, after the activated carbon binder enters the drying cylinder 1 through the feed inlet, it moves along the inner wall of the drying cylinder 1 towards the discharge outlet under the action of gravity. During the movement, the heating layer 4 heats and dries the binder. The moisture in the binder evaporates and rises with the heated air, and contacts the hollow rotating shaft 2, so that the water vapor passes through the through holes 21 and combines with the desiccant bag 7. Since the hollow rotating shaft 2 is rotating, the desiccant bag 7 also rotates accordingly, avoiding the problem of uneven water absorption. Moreover, a plurality of sub-packaging bags 71 are provided on the desiccant bag 7, so that the desiccant is dispersed in the plurality of sub-packaging bags 71, increasing the surface area of contact between the desiccant and the water vapor, improving the drying efficiency. When the desiccant in the desiccant bag 7 is fully saturated with water, the sealing cover 22 can be removed to replace the inner desiccant bag 7.

[0032] In the above-mentioned technology, the heating layer 4 heats and dries the binder. After the moisture in the binder evaporates, it rises with the heated air and contacts the hollow rotating shaft 2, enabling the water vapor to pass through the through-hole 21 and combine with the desiccant bag 7. Since the hollow rotating shaft 2 is rotating, the desiccant bag 7 also rotates accordingly, avoiding the problem of uneven water absorption. Moreover, multiple sub-bags 71 are provided on the desiccant bag 7, improving the drying efficiency. When the desiccant in the desiccant bag 7 has fully absorbed water, the cover 22 can be removed to replace the internal desiccant bag 7.

[0033] As a further embodiment provided by the present utility model, a drying hot air blower 5 and an exhaust port 6 are respectively arranged on the first side of the drying cylinder 1 from bottom to top.

[0034] Specifically, a drying filter screen is assembled on the exhaust port 6 to prevent moisture from entering the drying cylinder 1. After the heating layer 4 heats the binder, the hot air rises and the cold air descends. At this time, the drying hot air blower 5 at the bottom blows air into the drying cylinder 1 to strengthen the air flow rate, and at the same time heats the cold air at the bottom. Moreover, the exhaust port 6 and the drying hot air blower 5 are located on the same side, so that the air flow will be blocked by the wind from the drying hot air blower 5 below when flowing out of the drying cylinder 1, extending the time of the hot air in the drying cylinder 1 and improving the drying efficiency.

[0035] As a further embodiment provided by the present utility model, an auger 3 is fixedly arranged on the hollow rotating shaft 2.

[0036] Specifically, the auger 3 can push the binder towards the discharge port direction, and at the same time plays a stirring effect to prevent the binder from caking. Moreover, since downwardly inclined air guiding ports 31 are provided on the auger 3, the hot air from the drying hot air blower 5 is guided downward by the air guiding ports 31 when passing through the auger 3 and contacts the binder, extending the flow path of the hot air.

[0037] As a further embodiment provided by the present utility model, a central column 24 is fixedly arranged inside the hollow rotating shaft 2, and a plurality of hooks 23 are fixedly arranged on the inner wall of the first end of the hollow rotating shaft 2.

[0038] Specifically, when assembling the desiccant bag 7, the desiccant bag 7 is wound around the outer wall of the central column 24 along the central column 24. The clamping member 72 on the first side of the desiccant bag 7 is clamped with the fastening member 73 on the third side, and the fixing belt 74 is fixed by the hook 23 to prevent the desiccant bag 7 from sliding inside the hollow rotating shaft 2.

[0039] Working principle: Since the drying cylinder 1 is arranged horizontally, after the activated carbon binder enters the drying cylinder 1 through the feed port, it is pushed by the auger 3 towards the discharge port. The auger 3 stirs the binder. During the movement, the heating layer 4 heats and dries the binder. After the moisture in the binder evaporates, it rises with the heated air. At this time, the drying hot air blower 5 below blows air into the drying cylinder 1 to strengthen the air flow rate and heat the cold air below. Since the auger 3 is provided with downwardly inclined air guiding ports 31, the hot air of the drying hot air blower 5 is guided downward by the air guiding ports 31 when passing through the auger 3 and contacts the binder, drying the binder more fully. Then the water vapor rises and contacts the hollow rotating shaft 2, enabling the water vapor to pass through the through holes 21 and combine with the desiccant bag 7. Since the hollow rotating shaft 2 is rotating, the desiccant bag 7 also rotates accordingly, avoiding the problem of uneven water absorption. Moreover, the desiccant bag 7 is provided with a plurality of sub-packaging bags 71, so that the desiccant is dispersedly packed in the plurality of sub-packaging bags 71, increasing the surface area of contact between the desiccant and the water vapor and improving the drying efficiency. When the desiccant in the desiccant bag 7 is fully absorbed with water, the cover 22 can be removed to replace the internal desiccant bag 7. When assembling the desiccant bag 7, wind the desiccant bag 7 around the outer wall of the central column 24 along the central column 24, engage the clamping member 72 on the first side of the desiccant bag 7 with the fastening member 73 on the third side, and fix the fixing belt 74 through the hook 23 to prevent the desiccant bag 7 from sliding within the hollow rotating shaft 2.

[0040] Only some exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
