Description

Technical Field

[0001] This utility model relates to the field of drying drums, and in particular to a drum-type drying device with strong sealing performance. Background Technology

[0002] The working principle of a drying drum is based on heat conduction and the contact between the material and the hot airflow. Wet material enters from the top of one end of the drum. As the drum rotates, the material is continuously lifted and scattered by the internal lifting plates, ensuring full contact with the hot airflow and thus achieving drying. Dry material is collected from the bottom of the other end of the drum. Hot air typically enters the drum from either the feed or discharge end and exits from the top of the other end.

[0003] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0004] High-temperature sealing strips are usually installed at the inlet pipe of the drying drum. However, these sealing strips are easily worn out, making replacement cumbersome and wasteful of fuel. Furthermore, worn-out sealing strips can lead to a large amount of oxygen entering the drum. When this oxygen comes into contact with the combustible wood shavings inside the drum, it poses a significant fire hazard. Utility Model Content

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] In the attached diagram, all identical reference numerals refer to the same components. Example

[0035] like Figure 1-3As shown, this utility model provides a drum-type drying device with strong sealing performance, including a drum shell 1, a feeding device 11 and a feeding port 12. A sealing assembly 13 is provided on one side of the drum shell 1. The sealing assembly 13 includes:

[0036] The roller housing 1 has an outer end 101 and an inner end 102. The outer end 101 is located on the front side of the roller housing 1, and the inner end 102 is located on the upper side of the outer end 101.

[0037] The reinforcing rib 2 has two sets of reinforcing blocks 201, one inside and one outside. The reinforcing rib 2 is located on one side of the outer end 101, and the two sets of reinforcing blocks 201 are located at the bottom of both sides of the reinforcing rib 2.

[0038] Among them, the reinforcing block 201 is attached to the outer end 101;

[0039] Fixed flange 3, fixed flange 3 is located on one side of the inner end 102;

[0040] Flange extension positioning ring 4 is disposed on one side of the fixed flange plate 3;

[0041] Among them, the fixed flange plate 3 and the flange extension positioning ring 4 are set at a ninety-degree angle;

[0042] The sealing skin fixing flange 5 is located on one side of the reinforcing rib 2 and the flange extension positioning ring 4.

[0043] The wear-resistant plate 6 of the sealing flange is disposed on one side of the feeding device 11;

[0044] The reinforcing triangle plate 7 is set on one side of the feeding device 11 and is in contact with the wear-resistant plate 6 of the sealing flange.

[0045] The high-temperature sealing skin 8 has a first end 801, a second end 802 and a third end 803. The first end 801 is located on one side of the sealing skin fixing flange 5, and the second end 802 is located on one side of the first end 801.

[0046] Sealing plate 9, the sealing plate 9 is disposed on one side of the first end 801;

[0047] The fixing screw 10 is located at the center of the fixing flange, the first end 801, and the sealing pressure plate 9.

[0048] Specifically, such as Figure 1-3As shown, the reinforcing rib 2 increases the rigidity of the sealing assembly 13, and the reinforcing block 201 provides support for the reinforcing rib 2, making the connection between the reinforcing rib 2, the sealing flange 5, and the drum shell 1 more stable. The sealing flange 5 improves the sealing performance between the drum shell 1 and the feed inlet 12. The flange extension positioning ring 4 further secures the sealing flange 5 to the drum shell 1, providing support for the sealing flange 5. The wear-resistant plate 6 of the sealing flange forms a seal with the high-temperature sealing skin 8 to prevent heat loss from the inside of the drum shell 1 and to prevent external oxygen from entering the inside of the drum shell 1, thus preventing a fire hazard. The high-temperature sealing skin 8 has excellent high-temperature resistance, wear resistance, and elastic recovery ability, which can effectively prevent material from leaking out of the drum during the drying process, avoiding material waste and environmental pollution. At the same time, the high-temperature sealing skin 8 can withstand the high-temperature and high-pressure environment inside the drum, ensuring the durability and stability of the sealing effect.

[0049] The outer end 101 is larger than the inner end 102. The outer end 101 and the inner end 102 are set at 45°. The reinforcing rib 2 is fixedly connected to the outer end 101. The sealing skin fixing flange 5 is fixedly connected to the flange extension positioning ring 4. The flange extension positioning ring 4 is set perpendicularly to the sealing skin fixing flange 5. The reinforcing rib 2 is set parallel to the flange extension positioning ring 4.

[0050] The sealing flange 5 has screw holes inside, and the first end 801 and the sealing plate 9 both have through holes inside. The sealing flange 5, the first end 801 and the sealing plate 9 are connected by a fixing screw 10.

[0051] The second end 802 is set at a 15° angle to the first end 801, and the third end 803 is also set at a 15° angle to the second end 802.

[0052] The wear-resistant plate 6 of the sealing flange, the reinforcing triangular plate 7, and the feeding device 11 are all fixedly connected, and the reinforcing triangular plate 7 and the wear-resistant plate 6 of the sealing flange are fixedly connected.

[0053] Specifically, such as Figure 1-3 As shown, the sealing flange wear-resistant plate 6, the reinforcing triangular plate 7, and the feeding device 11 form an integral structure through a fixed connection. This integral structure helps to disperse and resist forces and pressures from all directions, thereby enhancing the stability of the entire equipment and increasing its service life.

[0054] Instructions for use: When the device is running, the material enters the inside of the drum shell 1 through the feed port 12. The drum shell 1 dries the material. The rotating drum shell 1 rotates with the high-temperature sealing skin 8. The high-temperature sealing skin 8 always abuts against the wear-resistant plate 6 of the sealing flange, so that the inside of the drum shell 1 is sealed, thereby preventing the heat inside the drum shell 1 from being lost. It can also effectively prevent external oxygen from entering the inside of the drum shell 1 and causing safety hazards.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
