Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a combined copying plate for high-humidity and high-viscosity materials. Background Art

[0002] In the field of drying equipment, traditional drying equipment often faces technical challenges, particularly when processing highly viscous and wet materials. Specifically, in current drying processes, drying equipment for industrial sludge and municipal waste typically utilizes a combination of lifting plates, movable chains, and movable impact plates. While this combination can achieve a certain degree of dispersion and mixing when processing materials with a moisture content ≥50%, it suffers from significant shortcomings due to limitations in its operating principle. Specifically, the material picked up by the lifting plates falls freely, and the acceleration of the material causes it to violently impact the dryer's drum. Due to the unique properties of highly viscous and wet materials, this impact can easily lead to severe adhesion between the material and the dryer drum. During the drying process, the material forms agglomerated particles, making it difficult to remove the crystallized water from these particles and severely affecting the drying equipment's operating efficiency and product quality.

[0003] In order to solve this problem, technicians have tried various methods, such as improving the structural design of the dryer, adjusting the drying process parameters, etc. However, these methods can only alleviate the problem to a certain extent, but cannot fundamentally solve the problem that high-humidity and high-viscosity materials are prone to sticking to the cylinder wall and forming agglomerates during the drying process. Therefore, it is necessary to develop a new type of drying equipment that can more effectively solve the problem that high-humidity and high-viscosity materials are prone to sticking to the cylinder wall and forming agglomerates during the drying process. The disclosure of this utility model is based on such technical background and actual needs, and proposes a combined copying plate for high-humidity and high-viscosity materials, which aims to improve the drying efficiency and product quality by improving the internal structure of the dryer, so as to meet the industry's demand for high-efficiency and high-quality drying equipment. Utility Model Content

[0004] The purpose of the utility model is to overcome the problem in the prior art that when a dryer processes high-humidity and high-viscosity materials, the materials should be prevented from adhering to the wall of the drying equipment over a large area and forming agglomerates. A combined lifting plate for high-humidity and high-viscosity materials is provided. The present invention utilizes a movable lifting plate unit consisting of an arc-shaped lifting plate and a movable striking plate to vibrate and disperse the materials raised by the sand-raising plate unit, thereby solving the problem that high-humidity and high-viscosity materials are easily adhered to the wall of the drying equipment and form agglomerates.

[0005] The utility model is realized through the following technical solutions: a combined scraping plate for high-humidity and high-viscosity materials, comprising a movable scraping plate assembly and a sand-raising plate assembly arranged on the inner wall of the dryer cylinder, the movable scraping plate assembly comprising a plurality of movable scraping plate units evenly distributed around an axis along the inner wall of the dryer cylinder, one inner end of the movable scraping plate unit is hingedly arranged, the sand-raising plate assembly comprising a plurality of sand-raising plate units evenly distributed around an axis along the inner wall of the dryer cylinder, the sand-raising plate unit is V-shaped, the movable scraping plate units and the sand-raising plate units are distributed at intervals, the movable scraping plate unit comprises a movable striking plate, an arc-shaped scraping plate is provided on the side of the movable striking plate facing away from the sand-raising plate unit, a material leakage gap is provided on the movable striking plate, and the arc-shaped scraping plate is bent inwardly toward the side of the movable striking plate.

[0006] In order to further optimize the present invention, the following technical solutions may be preferably selected:

[0007] Preferably, the sand-raising plate unit includes a plate body, a first bending portion is provided at the end of the plate body, the plate body is arranged radially along the dryer cylinder, and the first bending portion is bent toward the movable striking plate.

[0008] Preferably, the bending angle between the first bending portion and the plate body is in the range of 120° to 180°.

[0009] Preferably, a supporting member is provided between the sand-raising plate unit and the movable striking plate. The supporting member is U-shaped, and both ends of the supporting member extend upward to a position between the free end of the sand-raising plate unit and the movable striking plate.

[0010] Preferably, the movable lifting plate assembly and the sand raising plate assembly are evenly arranged in a spiral manner on the inner wall of the dryer cylinder.

[0011] Preferably, the movable lifting plate components and sand-raising plate components are arranged in multiple rows around the axis.

[0012] Preferably, the movable striking plate includes a bottom plate and a top plate, a plurality of striking rods are radially arranged on the bottom plate and the top plate, the bottom plate is rotatably arranged on the dryer cylinder through a rotating shaft, and the two ends of the arc-shaped lifting plate are respectively arranged on the bottom plate and the top plate.

[0013] The utility model has the following effects:

[0014] (1) The combined scraping plate in this equipment utilizes the movable striking plate in the original drying process. On the basis of the original one, an arc-shaped scraping plate is installed on the back to form a tangent relationship with the dryer cylinder. Since the material picked up by the lifting scraping plate moves freely, the material that should have violently hit the cylinder wall under the action of acceleration now falls directly into the combined scraping plate. Since the front half of the combined scraping plate is a movable striking plate, all the material will fall into the arc-shaped scraping plate matched with it. When the cylinder rotates to the upper end, the movable striking plate is affected by gravity and collides with the adjacent lifting scraping plate, which will shake up all the material falling into the arc-shaped scraping plate and drop it to the bottom to continue repeating the process.

[0015] (2) The main problem of drying high-humidity and high-viscosity materials lies in the front section of the drying equipment. The combined lifting plate makes it difficult for the material to come into direct contact with the drying cylinder because the curved lifting plate on the back is tangent to the drying cylinder. The movable striking plate can repeatedly lift and disperse the material, thereby reducing the material's adhesion to the drying cylinder and the occurrence of agglomeration during the material's own operation.

[0016] (3) Reduce equipment wear and maintenance frequency: Due to the improved vibration dispersion effect, the adhesion between the material and the drying equipment cylinder wall is greatly reduced, which means that the wear and tear of the equipment during operation will be reduced accordingly. Therefore, the maintenance frequency and maintenance cost of the equipment will also be reduced accordingly, thereby extending the service life of the equipment.

[0017] (4) Structural stability: The support design between the sand-raising plate unit and the movable striking plate enhances the structural stability of the equipment. This design not only effectively prevents materials from leaking from the equipment during the drying process, but also reduces vibration and noise during operation.

The sand-raising plate assembly includes a plurality of sand-raising plate units evenly distributed around the axis along the inner wall of the dryer cylinder, and the sand-raising plate unit is V-shaped, wherein the sand-raising plate unit includes a plate body 5, and a first bending portion 6 is designed at the end of the plate body 5. The plate body is arranged radially along the dryer cylinder, and the first bending portion 6 is bent toward the movable striking plate. The first bending portion 6 and the plate body 5 are respectively provided. The bending angle range between them is 120° to 180°; the movable copying plate unit and the sand-raising plate unit are distributed at intervals, and the movable copying plate unit includes a movable striking plate. A curved copying plate is installed on the side of the movable striking plate away from the sand-raising plate unit, and a leakage gap is designed on the movable striking plate, and the curved copying plate is bent inward toward the side of the movable striking plate; as the specific design structure of the movable striking plate in this embodiment, the movable striking plate includes a bottom plate 7 and a top plate 8. A plurality of striking rods 9 are radially arranged on the bottom plate 7 and the top plate 8. The bottom plate is rotatably arranged on the dryer cylinder through a rotating shaft, and both ends of the curved copying plate 10 are welded to the bottom plate 7 and the top plate 8 respectively. The combined copying plate in this equipment utilizes the movable striking plate in the original drying process. On the basis of the original one, an arc-shaped copying plate is installed on the back to form a tangent relationship with the dryer cylinder.

Both ends of the support member 4 extend upward to the position between the free end of the sand-raising plate unit and the movable striking plate. This support member design between the sand-raising plate unit and the movable striking plate enhances the structural stability of the equipment. This design not only effectively prevents material from leaking out of the equipment during the drying process, but also reduces vibration and noise during operation.
