Description

Technical Field

[0001] This utility model relates to the field of carbon black production technology, and in particular to a scraper distribution structure for improving drying efficiency. Background Technology

[0002] Rotary drum dryers are commonly used drying equipment in industrial production. They use lifting plates inside the drum to lift and drop materials, forming a material curtain to increase the contact area between the materials and the hot flue gas, thereby improving drying efficiency.

[0003] The original drying drum lifting plates were made of 316L stainless steel, with 10 rows of 8 plates each, totaling 80 plates. The limited number of plates meant that the carbon black was gradually dried inside the drum, resulting in high moisture content and strong corrosiveness at the front end. Each time the drum was opened for inspection, the lifting plates showed varying degrees of corrosion. With only 80 plates, the carbon black material could not be fully lifted to achieve maximum contact with the hot flue gas, leading to a waste of heat energy. Utility Model Content

[0004] The problem solved by this utility model is to provide a lifting plate distribution structure that improves drying efficiency. It solves the technical problem that the original drying drum lifting plate material is 316L, the lifting plates are divided into 10 rows of 8 plates each, for a total of 80 lifting plates. The number of lifting plates is small. Since the carbon black enters the drum and dries gradually, the front end has a high moisture content and strong corrosiveness. Every time the cover is opened for inspection, the lifting plates show different degrees of corrosion. With only 80 lifting plates, it is not possible to fully lift the carbon black material to achieve maximum contact area with the hot flue gas, resulting in the waste of heat energy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A lifting plate distribution structure for improving drying efficiency includes a first roller mechanism, a second roller mechanism, a third roller mechanism, and a fourth roller mechanism connected in sequence.

The second roller mechanism is a front section and a middle section at the feeding end, including a third cylinder body, and several rows of first lifting plates are installed inside the third cylinder body. The fourth roller mechanism is a rear section at the feeding end, including a fourth cylinder body, and several rows of second lifting plates are installed inside the fourth cylinder body.

[0006] Preferably, the first cylinder is equipped with three rows of guide vanes, each row of guide vanes is circular, and there are 24 guide vanes in each row. The guide vanes are arranged at 45°.

[0007] Preferably, a first bolt post is installed on the guide plate, and the first bolt post passes through the first cylinder and is connected to the first nut.

[0009] Preferably, a second bolt post is installed on the guide plate, and the second bolt post passes through the second cylinder and the pad and is connected to the second nut.

[0010] Preferably, the third cylinder is equipped with fifty-three rows of first lifting plates, and each row of first lifting plates is arranged in a circle, with 24 first lifting plates in each row.

[0011] Preferably, a third bolt post is installed on the first lifting plate, and the third bolt post passes through the third cylinder and is connected to the third nut.

[0012] Preferably, the fourth cylinder is equipped with twenty-nine rows of second lifting plates, and each row of second lifting plates is arranged in a circle, with 30 second lifting plates in each row.

[0013] Preferably, a fourth bolt post is installed on the second lifting plate, and the fourth bolt post passes through the fourth cylinder and is connected to the fourth nut.

[0014] Preferably, the first, second, third, and fourth cylinders are equipped with connecting rings at their ends, and the connecting rings between adjacent cylinders are assembled and connected by fixing bolts and fixing nuts.

The guide plates 6 are equipped with first bolt posts 7, which pass through the first cylinder 5 and are connected to the first nut 8, so as to realize convenient disassembly and assembly of the guide plates 6.

[0022] The second cylinder 9 is equipped with four rows of guide plates 10, each row of guide plates 10 is circular, and there are 24 guide plates 10 in each row. The guide plates 10 are set at 45°. The guide plates 10 are equipped with second bolt posts 11, which pass through the second cylinder 9 and the pad block 12 and are connected to the second nut 13, so as to realize convenient disassembly and assembly of the guide plates 10.

[0023] The third cylinder 14 is equipped with fifty-three rows of first lifting plates 15, and each row of first lifting plates 15 is arranged in a circle. There are 24 first lifting plates 15 in each row. A third bolt post 16 is installed on the first lifting plate 15, and the third bolt post 16 passes through the third cylinder 14 and is connected to the third nut 17, so as to realize convenient disassembly and assembly of the first lifting plate 15.

[0024] The fourth cylinder 18 is equipped with twenty-nine rows of second lifting plates 19, and each row of second lifting plates 19 is arranged in a circle. There are 30 second lifting plates 19 in each row. The second lifting plates 19 are equipped with fourth bolt posts 20, and the fourth bolt posts 20 pass through the fourth cylinder 18 and are connected to the fourth nut 21, so as to realize the convenient assembly and disassembly of the second lifting plates 19.

The first cylinder 5, the second cylinder 9, the third cylinder 14, and the fourth cylinder 18 are assembled and connected by connecting rings 22, fixing bolts, and fixing nuts. As the cylinder rotates, the guide plate 10 quickly pushes the material from the first cylinder 5 into the second cylinder 9. The material entering the second cylinder 9 quickly enters the third cylinder 14 under the centripetal force of the cylinder rotation and the guiding action of the guide plate 10. The material entering the third cylinder 14 and the fourth cylinder 18 is continuously lifted and thrown down by the lifting plates as the cylinder rotates, and moves backward stably, breaking up agglomerates and forming a uniform "material curtain" of carbon black. This maximizes the contact area between the material and the flue gas inside the drum, making full use of the heat source for material drying, and avoiding the problem of incomplete or over-drying due to uneven heating caused by local material accumulation.

[0027] The drum is equipped with specially distributed guide plates 6, guide plates 10 and lifting plates so that the material forms a uniform material curtain during the drum rotation process, and the maximum area is in contact with the hot flue gas, which improves the heat utilization rate, reduces fuel consumption, reduces material accumulation, and avoids the problem of incomplete drying or over-drying due to uneven heating caused by local material accumulation. The guide plate 6, the guide plate 10, and the lifter plate are all connected to the cylinder by bolts and nuts, which facilitates the disassembly and replacement of the guide plate 6, the guide plate 10, and the lifter plate, reducing the cost of use.
