Description

Technical Field

[0001] This utility model belongs to the field of rotary kiln technology, and in particular relates to a device for sealing fish scales in a rotary kiln. Background Technology

[0002] Currently, in enterprises producing pellets using a chain grate machine-rotary kiln-annular cooler system, the rotary kiln is the rotating component. The seal between its head and the fixed screen chamber uses a fish-scale contact seal. To ensure tight contact between the fish-scale seals and the kiln body, graphite blocks are often installed between the fish-scale seals and the kiln shell, and then the fish-scale seals are tightly bound with steel wire ropes. This does improve the sealing effect and reduce heat loss. However, there are two drawbacks: first, as the graphite blocks wear down, the tension of the steel wire ropes weakens, and the seal becomes less tight; second, when the graphite blocks form rings inside the kiln, many large pieces fall, causing kiln vibration and frequently breaking the steel wire ropes. Since the production line operates continuously 24 hours a day, it cannot be stopped arbitrarily and can only be addressed during maintenance, resulting in heat loss during normal operation and dust overflow from the kiln. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a device for sealing the fish-scale plates of a rotary kiln. This solves the problems of weakened tension of the steel wire rope on the fish-scale plates of the rotary kiln, resulting in an incomplete seal and the steel rope breaking.

[0004] This utility model discloses a rotary kiln fish-scale sealing device, comprising a rotary kiln body and fish-scales. The fish-scales are characterized in that: the fish-scales are disposed on the kiln head of the rotary kiln, and a tensioning device is provided on the fish-scales. The tensioning device includes two fixed pulleys A and B, a steel wire rope, and a damping assembly. The damping assembly includes a left connecting plate, a right connecting plate, a steel chain, and a damping spring. The steel chain is longer than the distance between the left and right connecting plates. The left end connector of the steel chain is fixedly connected to the upper end of the left connecting plate, and the right end connector of the steel chain is fixedly connected to... The upper end of the right connecting plate is fixedly connected; the damping spring is arranged parallel to the lower end of the steel chain, the short connecting end of the damping spring is fixedly connected to the lower end of the left connecting plate, and the long connecting end is fixedly connected to the lower end of the right connecting plate; the steel wire rope is tied around the outside of the fish scale, and after the two ends of the steel wire rope cross at the lower part of the fish scale, the right end of the steel wire rope passes over the fixed pulley A and is fixedly connected to the left connecting plate, and the left end of the steel wire rope passes over the fixed pulley B and is fixedly connected to the right connecting plate; a tension gauge with a remote alarm device is connected to the long connecting end of the damping spring.

[0005] Preferably, a protective cover is installed on the damping assembly.

[0006] The advantages of this utility model are:

[0007] This invention allows the fish-scale pattern to adhere tightly to the kiln head. If the wire rope tension becomes too high, exceeding the alarm threshold, an alarm signal is transmitted to the work rest area, alerting personnel to take immediate action. In cases of excessive tension, the upper steel chain acts as a restraint mechanism, preventing damage to the damping spring and effectively solving the problems of inadequate sealing and wire rope breakage. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] like Figure 1 As shown, this utility model discloses a rotary kiln fish-scale sealing device, comprising a rotary kiln body and fish-scale 1. The fish-scale 1 is positioned on the kiln head 2 of the rotary kiln, and a tensioning device is provided on the fish-scale 1. The tensioning device includes two fixed pulleys A31 and B32, a steel wire rope 33, and a damping assembly. The damping assembly includes a left connecting plate 34, a right connecting plate 35, a steel chain 36, and a damping spring 37. The steel chain 35 is longer than the distance between the left and right connecting plates 34 and 35, and the left end connector of the steel chain is fixedly connected to the upper end of the left connecting plate 34. The right end connector of the steel chain is fixedly connected to the upper end of the right connecting plate 35; the damping spring 37 is arranged parallel to the lower end of the steel chain 36, with the short connector 371 of the damping spring 37 fixedly connected to the lower end of the left connecting plate 34 and the long connector 372 fixedly connected to the lower end of the right connecting plate 35; the steel wire rope 33 is tied around the outside of the fish scale 1, and after the two ends of the steel wire rope cross at the lower part of the fish scale, the right end 331 of the steel wire rope 33 passes over the fixed pulley A31 and is fixedly connected to the left connecting plate 34, and the left end 332 of the steel wire rope passes over the fixed pulley B32 and is fixedly connected to the right connecting plate 35. The function of the two fixed pulleys is to change the direction of the force, so that the steel wire rope 33 is fully tightened and pressed on the fish scale; when the kiln body moves or vibrates, the damping spring 37 ensures that the steel wire rope 33 has tension.

[0011] This utility model features a tension gauge 4 with a remote alarm function on the long connector 372 of the damping spring. When the damping spring 37 extends to its maximum extent, the steel chain 36 will be pulled apart. If the tension exceeds the set tension value, an alarm signal is output, and the audible and visual alarm device installed in the rest room is activated to remind the staff to take timely measures to deal with the situation. At the same time, it also effectively protects the damping spring 37 from being broken.

[0012] This utility model has a protective cover 5 installed on the damping component. The function of the protective cover is to seal and protect the entire damping device, and to avoid interference and damage from the external environment.

[0013] It should be noted that in the description of this utility model, the terms "length", "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
