Description

Technical Field

[0001] This utility model relates to the field of material drying equipment technology, and in particular to a multi-layer guide plate type graphite material dryer. Background Technology

[0002] A disc dryer is a device that continuously dries materials using multiple horizontal heating discs, and is widely used in chemical, food, and pharmaceutical industries. Traditional disc dryers typically use a main shaft to drive multiple drying discs to rotate, achieving material dehydration through heat conduction and hot air convection.

[0003] During the processing of graphite materials, a disc dryer is used for drying. However, the disc dryers currently in use have low thermal efficiency: the drying discs are generally single-layer solid structures, and heat is only conducted through the surface, resulting in insufficient internal heat exchange and wasted heat energy; the material distribution is uneven: the surface of the drying discs lacks a flow guiding design, and the material is prone to accumulate or form "dead zones", resulting in poor drying uniformity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-layer guide plate type graphite material dryer that facilitates material dispersion and improves material drying efficiency.

[0005] According to an embodiment of this utility model, a multi-layer guide plate type graphite material dryer includes a casing, a vertically arranged main shaft, a drive mechanism for driving the main shaft to rotate, a hot air mechanism, and a control system. Multiple parallel drying discs evenly distributed along the axial direction are detachably connected to the main shaft. Each drying disc includes a heat-conducting layer, a support layer, and a wear-resistant layer arranged sequentially from the lower right to the upper right. The support layer has a honeycomb structure. A set of hot air mechanisms facing the upper surface of each drying disc is provided above it.

[0006] Preferably, the top of the support layer is fixedly provided with guide ribs arranged radially along its radial direction.

[0007] More preferably, the height of the guide rib gradually increases from 2mm to 8mm from the center to the edge, and the included angle between adjacent guide ribs is 10°-15°.

[0008] More preferably, the cross-section of the guide rib is trapezoidal, with a top surface width of 1-2 mm and a bottom surface width of 3-5 mm, and the top of the guide rib is provided with a wavy groove.

[0009] More preferably, the heat-conducting layer is provided with a flow guide groove communicating with the pores of the support layer, the inner wall of the housing is provided with a flow guide seat that is rotatably and sealingly connected to the heat-conducting layer, the flow guide seat is provided with a water collection tank communicating with the flow guide groove, and the water collection tank is connected to a drain pipe.

[0010] More preferably, a piezoelectric ceramic vibrating plate is fixed to the bottom of the thermally conductive layer.

[0011] In a further preferred embodiment, the inner side of the heat-conducting layer is connected to the main shaft via a quick-release flange.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The drying tray is equipped with a multi-layer structure, including a heat-conducting layer, a support layer, and a wear-resistant layer. The honeycomb support layer facilitates the removal of moisture from the material surface, the heat-conducting layer improves heat transfer, and the wear-resistant layer made of silicon carbide ceramic material has wear-resistant and non-stick properties. The support layer, together with the hot air mechanism facing its surface, can accelerate the passage of moisture from the material surface through the support layer, which is conducive to the separation of moisture from the material and improves drying efficiency.

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] This utility model provides an embodiment, such as Figure 1 , Figure 2As shown, a multi-layer guide plate type graphite material dryer includes a housing 1, a vertically arranged main shaft 2, a drive mechanism 3 for driving the main shaft 2 to rotate, a hot air mechanism 4, and a control system. The housing 1 is a cylindrical stainless steel shell. Multiple parallel drying discs 6 are detachably connected to the main shaft 2 and are evenly distributed along its axial direction. In this embodiment, three drying discs 6 are provided, with a spacing of 200mm between them. Each drying disc 6 includes a heat-conducting layer 601, a support layer 602, and a wear-resistant layer 603 arranged sequentially from the lower right to the upper left. The heat-conducting layer 601 is a copper-aluminum alloy with a thickness of 3mm. The support layer 602 is a honeycomb structure made of stainless steel with a thickness of 15mm, a pore size of 0.8mm, and a porosity of 78%. The wear-resistant layer 603 is a silicon carbide ceramic with a thickness of 0.5mm. A set of hot air mechanisms 4 is provided above each drying disc 6 and faces its upper surface.

[0019] During drying, the wet material is distributed on the top of the support layer 602. The main shaft 2 drives the drying tray 6 to rotate slowly. The material is evenly dispersed under the action of centrifugal force, and the water on the material is discharged from the pores of the support layer 602. At the same time, the hot air mechanism 4 above the material can facilitate the flow of water down and accelerate the evaporation of water on the surface of the material.

[0020] To facilitate material dispersion, in a further embodiment, the top of the support layer 602 is fixedly provided with guide ribs 604 arranged radially along its radial direction. The guide ribs 604 are arranged radially with the center of the drying tray 6 as the origin, forcing the material to move outward along the gap between the ribs under the action of centrifugal force, avoiding accumulation in the central area or the formation of dead zones.

[0021] To prevent material from scattering, in a further embodiment, the height of the guide rib 604 gradually increases from 2mm to 8mm from the center to the edge, and the included angle between adjacent guide ribs 604 is 10°-15° to adapt to material thickness changes at different radius positions. The increased outer edge height can prevent material from splashing during high-speed rotation.

[0022] In order to increase the heat exchange area of ​​the material, in a further embodiment, the cross-section of the guide rib 604 is trapezoidal, with a top surface width of 1-2 mm and a bottom surface width of 3-5 mm. The top of the guide rib 604 is provided with a wavy groove 605, which can effectively increase the heat exchange area between the guide rib 604 and the material. At the same time, the groove 605 generates turbulence when hot air passes through, which improves the heat transfer coefficient of hot air to the material.

[0023] To facilitate water drainage, in a further implementation method, such as... Figure 2As shown, the heat-conducting layer 601 is provided with a flow channel 606 that communicates with the pores of the support layer 602. The inner wall of the housing 1 is provided with a flow seat 607 that is rotatably and sealingly connected to the heat-conducting layer 601. The flow seat 607 is provided with a water collection tank 608 that communicates with the flow channel 606. The water collection tank 608 is connected to a drain pipe 609.

[0024] In order to accelerate the removal of moisture from the material, in a further embodiment, a piezoelectric ceramic vibrating plate 5 is fixed to the bottom of the heat-conducting layer 601, and the piezoelectric ceramic vibrating plate 5 is connected to the control system.

[0025] To facilitate the installation and removal of the drying tray 6, in a further embodiment, the inner side of the heat-conducting layer 601 is connected to the main shaft 2 via a quick-release flange 610.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
