Description

Technical Field

[0001] The utility model relates to the technical field of carbonization equipment sealing, in particular to a flue elastic extrusion device. Background Art

[0002] During the operation of the carbonization equipment, the sealing between the rotating furnace body and the flue casing is of vital importance. Since the carbonization process involves high temperatures and complex chemical reactions, the temperature inside the furnace body fluctuates greatly, which causes the furnace body to easily deform when heated. The sealing device between the rotating furnace body and the flue casing of the existing carbonization equipment generally uses a clamp to directly wrap the sealing material around the outside of the rotating furnace body. After the equipment has been running for a period of time, the thermal deformation of the furnace body often leads to insufficient pre-tightening force of the sealing device, resulting in sealing leakage; or the pre-tightening force increases, resulting in excessive resistance to the rotation of the furnace body, affecting the normal operation of the equipment. Traditional sealing methods are often difficult to adapt to this deformation, resulting in poor sealing, which in turn causes gas leakage, heat loss, and environmental pollution during the carbonization process.

[0003] In order to solve the above problems, there are already some sealing devices on the market, but these devices are often complex in structure, difficult to maintain, and the sealing effect is not ideal. Especially in the case of furnace deformation, these devices often cannot effectively maintain the sealing, resulting in serious impact on the carbonization process. Therefore, the development of a carbonization equipment sealing device that can adapt to furnace deformation and maintain a good sealing effect has become an urgent problem to be solved in the current field of carbonization equipment technology. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems existing in the prior art and to provide a flue elastic extrusion device, which can elastically and tightly press the sealing material around the rotating furnace body. During the operation of the equipment, the rotating furnace body is often deformed due to the increase in temperature caused by heating. At this time, the elastic pressing sheet in the deformed area also deforms as the shape of the cylinder changes, ensuring that the sealing material is squeezed around the rotating furnace body without gaps, ensuring that the sealing device always maintains a good sealing effect during the heating or cooling process of the rotating furnace body.

[0005] The utility model is realized through the following technical scheme: a flue elastic extrusion device, comprising a circular ring-shaped sealing belt arranged between a rotating furnace body and a flue casing of a carbonization device, an elastic pressing mechanism is arranged on the flue casing at a position corresponding to the outer side of the sealing belt, the elastic pressing mechanism is used to press the sealing belt against the surface of the rotating furnace body, the elastic pressing mechanism comprises a plurality of elastic pressing sheets arranged on the flue casing, and the plurality of elastic pressing sheets are stacked in sequence and arranged in a ring shape around the rotating furnace body.

[0006] In order to further optimize the utility model, the following technical solutions can be preferably used:

[0007] Preferably, the elastic pressing piece comprises a connected fixing section, a transition section and a pressing section, the elastic pressing piece is detachably arranged on the flue casing, and the pressing section extends to the outer wall of the rotating furnace body and fits the outer wall of the rotating furnace body.

[0008] Preferably, the fixing section, transition section and pressing section are integrally formed.

[0009] Preferably, a plurality of bolt fixing holes are provided on the fixing section, and two adjacent elastic pressing sheets share one bolt fixing hole.

[0010] Preferably, the bolt fixing hole is a long waist hole.

[0011] Preferably, the elastic pressing piece is a rigid plate.

[0012] The beneficial effects of the utility model are mainly reflected in the following aspects:

[0013] The flue elastic extrusion device of the utility model realizes effective sealing of the rotating furnace body by adopting a circular sealing belt and an elastic pressing mechanism arranged on the flue casing. This design is not only simple in structure, but also easy to maintain, which greatly improves the operating efficiency and stability of the carbonization equipment. Specifically, a plurality of elastic pressing sheets in the elastic pressing mechanism are stacked in sequence and arranged in a ring shape around the rotating furnace body, which can fit the furnace body surface tightly and effectively prevent gas leakage and heat loss. At the same time, since the elastic pressing sheet is elastic, it can be adaptively adjusted with the deformation of the furnace body, and always maintain a good sealing effect. In addition, by optimizing the structural design of the elastic pressing sheet, such as adopting an integrated molding structure of a fixed section, a transition section, and a pressing section, and setting a bolt fixing hole and a long waist hole, the stability and reliability of the device are further enhanced. At the same time, the detachable setting method also facilitates the maintenance and replacement of the device. Finally, the sealing belt adopts a U-shaped cross-section design, and uses a double-layer sealing material to improve the sealing effect, further enhancing the sealing performance of the device. To sum up, the flue elastic extrusion device of the utility model has the advantages of simple structure, easy maintenance, good sealing effect, etc. It can effectively solve the sealing problems occurring during the operation of the carbonization equipment, improve the operating efficiency and stability of the equipment, and has broad application prospects.

This design is not only simple in structure, but also convenient in maintenance, which greatly improves the operating efficiency and stability of the carbonization equipment. Specifically, the multiple elastic compression sheets in the elastic compression mechanism are stacked in sequence and arranged in a ring shape around the rotating furnace body, which can closely fit the surface of the furnace body and effectively prevent gas leakage and heat loss. At the same time, since the elastic compression sheets are elastic, they can be adaptively adjusted with the deformation of the furnace body, always maintaining a good sealing effect.

[0024] The elastic pressing piece includes a connected fixing section 8, a transition section 9 and a pressing section 10. The elastic pressing piece can be detachably mounted on the flue casing. The pressing section extends to the outer wall of the rotating furnace body and fits the outer wall of the rotating furnace body.
