Description

Technical Field

[0001] The utility model relates to a drying cylinder end sealing structure, which is mainly used for sealing the inlet and outlet ends of a drum dryer. The utility model belongs to the technical field of drum drying equipment. Background Art

[0002] The drum dryer is a type of drying equipment. The drum is generally placed at an angle through a support ring, and dry gas is passed through the drum. During operation, the drum rotates along the center line of the drum. When the drum rotates, the material inside the drum is lifted from the bottom by the lifting plate. During the rising process, the material continuously falls from the lifting plate. During this process, the material in the drum is fully in contact with the dry gas to achieve the purpose of drying. For existing drums, see CN215766186U.

[0003] The shortcomings of the existing technology: the interface size of the drying drum is relatively large, and the drying drum is often produced by rolling steel plates and then welding them. Due to the production process of the drying drum, there are processing errors in the concentricity of the drum rotation and fixed installation, and there are port jumps at the feed port and the discharge port, which affects the sealing of the feed port and the discharge port, and ultimately affects the drying effect. Summary of the invention

[0004] The purpose of the utility model is to provide a drying drum end sealing structure, and the purpose to be achieved is to use a simple structure to achieve reliable sealing of the inlet and outlet of the drying drum.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The drying cylinder end sealing structure includes a connecting cone plate, an angle steel flange, a spring strip and a brake band, and is characterized in that: one of the angle steel flanges is fixedly connected to the connecting cone plate, and the brake band is fixedly connected to the other angle steel flange; one end of the spring strip is fixedly connected to the connecting cone plate, and the other end of the spring strip is in contact with the brake band.

[0007] As an improvement of the utility model, the angle steel flange is feed port angle steel flange one and feed port angle steel flange two, the connecting cone plate is feed port connecting cone plate; the spring pressure strip is fixedly connected to the feed port connecting cone plate by bolts; the brake band is fixed to feed port angle steel flange two by screws.

[0008] As an improvement of the utility model, the angle steel flange is discharge port angle steel flange one and discharge port angle steel flange two, the connecting cone plate is the discharge port connecting cone plate; the spring pressure strip is fixedly connected to the discharge port connecting cone plate by bolts; the brake band is fixed to the discharge port angle steel flange one by screws.

[0009] As an improvement of the utility model, a third angle steel flange of the material outlet is further provided, and the third angle steel flange of the material outlet is welded to the second angle steel flange of the material outlet.

[0010] As an improvement of the utility model, the spring strip is composed of a straight section and a bent section, the straight section of the spring strip is fixedly connected to the connecting cone plate, and the bent section of the spring strip is in contact with the brake belt.

[0011] As an improvement of the present invention, the main body of the brake band is in a circular ring shape, and the main body of the brake band is composed of 3-8 fan-shaped brake band components.

[0012] Beneficial effects after adopting the above technical solution:

[0013] 1) A simple structure including a connecting cone plate, a spring pressure strip and a brake belt is adopted. The elastic pressure strip can be effectively pressed on the brake belt to achieve reliable sealing of the inlet and outlet of the drying drum.

[0014] 2) The feed port and the discharge port adopt angle steel flange structure, which is convenient for sealing connection with the drying drum on the one hand, and can use the right-angle surface of the angle steel to provide a relatively flat sealing contact surface for the brake belt on the other hand, thereby improving the sealing performance.

[0015] 3) The spring strip with a specific structure can adapt to the port jump, so that the bent section of the spring strip can reliably contact the brake belt to ensure the sealing effect.

[0016] 4) When the brake band assembly in a certain area is worn too much, the brake band assembly in that area can be easily replaced to save costs. BRIEF DESCRIPTION OF THE DRAWINGS
