The diameter of the disc 5, the rim of the smaller diameter heating disc 5 is provided with a scraper 8 for scraping off the material adhering to the surface of the larger diameter heating disc 5 and pushing the material to move from the material inlet 1b to the material outlet 1c.
具体来说，同一根主轴3上的加热盘5的边沿和机壳1之间距离相同。Specifically, the distance between the edge of the heating plate 5 on the same main shaft 3 and the casing 1 is the same.
锅炉中的高温蒸汽通过管路一和进气孔3b1连通，使得高温蒸汽进入到空腔3c实现给主轴3加热，空腔3c内的高温蒸汽还通过空腔3c进入到加热盘5中的蒸汽腔5h内，实现给加热盘5加热，机壳1的物料通过和主轴3以及加热盘5接触实现去除水分实现干燥的目的，经过热交换以后的蒸汽和凝水通过出气孔3a1排出到锅炉中再次进行加热，节约能源。The high-temperature steam in the boiler communicates with the intake hole 3b1 through the pipe 1, so that the high-temperature steam enters the cavity 3c to heat the main shaft 3, and the high-temperature steam in the cavity 3c also enters the steam in the heating plate 5 through the cavity 3c. In the chamber 5h, the heating plate 5 is heated, and the material of the casing 1 is contacted with the main shaft 3 and the heating plate 5 to achieve the purpose of removing moisture, and the steam and condensed water after the heat exchange are discharged into the boiler through the air outlet 3a1. Heat again to save energy.
具体来说，管路一和进气孔3b1之间转动连接并且管路一和进气孔3b1之间密封设置，所述管路一上还设置有蒸汽输送泵。出气孔3a1通过管路二和锅炉连通，管路二和出气孔3a1之间转动连接并且管路二和出气孔3a1之间密封设置。Specifically, the pipeline 1 and the air inlet hole 3b1 are rotatably connected and the pipeline 1 and the air inlet hole 3b1 are sealed, and the pipeline is further provided with a steam delivery pump. The air outlet 3a1 is connected to the boiler through the pipeline 2, the pipeline 2 and the air outlet 3a1 are rotatably connected, and the pipeline 2 and the air outlet 3a1 are sealed.

[根据细则91更正 17.05.2019]　
所述主轴3相邻的两个加热盘5之间形成烘干通道5a，各个烘干通道5a的宽度均相同，所述刮刀8位于直径较大的两个加热盘5之间并且刮刀8和两侧的两个加热盘5之间具有间隙，两根主轴3分别由两个动力件带动，两个动力件带动两根主轴3同向转动，所以直径较小的加热盘5在转动的过程中，刮刀8可以带动位于刮刀8两侧的直径较大的加热盘5之间的物料移动，物料的移动会挤压直径较大的加热盘5的侧壁，使得黏在直径较大的加热盘5侧壁上的物料收到挤压后被刮除，同时受到挤压的物料也会带走黏在直径较小的加热盘5侧壁上的物料，可以实现用于干燥黏性物料的目的并且干燥效果好，另外本真空双轴干燥机还可以干燥粉末状的物料适用范围广。[Correct according to Rule 91 17.05.2019]
A drying channel 5a is formed between the two heating plates 5 adjacent to the main shaft 3, and the widths of the respective drying channels 5a are the same. The scraper 8 is located between the two heating plates 5 having a larger diameter and the scraper 8 and There are gaps between the two heating plates 5 on both sides, the two main shafts 3 are respectively driven by two power parts, and the two power parts drive the two main shafts 3 to rotate in the same direction, so the heating disk 5 with a smaller diameter is rotating. In the middle, the scraper 8 can drive the material moving between the larger diameter heating discs 5 on both sides of the scraper 8. The movement of the material will squeeze the side wall of the larger diameter heating disc 5, so that the heat is adhered to the larger diameter. The material on the side wall of the disk 5 is scraped off after being squeezed, and the extruded material also carries away the material adhered to the side wall of the smaller diameter heating plate 5, which can be used for drying the viscous material. The purpose and the drying effect are good, and the vacuum double-axis dryer can also dry the powdery material for a wide range of applications.
作为优选，所述机壳1上设置有真空泵，该真空泵用于给机壳1的内部抽真空。机壳1内处于真空状态可以实现低温干燥，避免物料受热变性。Preferably, the casing 1 is provided with a vacuum pump for evacuating the inside of the casing 1. The vacuum inside the casing 1 can achieve low temperature drying to avoid heat denaturation of the material.
具体来说，所述机壳1的外壁上设置有若干根加强筋1a。 所述加强筋1a首尾相连现场一个整体，加强筋1a的设置可以提高机壳1的结构强度，防止机壳1发生变形而导致加热盘5和机壳1之间距离不均匀，从而导致机壳1内物料的移动量不均匀，使得物料的干燥不均匀，影响干燥的效果。Specifically, the outer wall of the casing 1 is provided with a plurality of reinforcing ribs 1a. The reinforcing ribs 1a are connected end to end in a whole body, and the arrangement of the reinforcing ribs 1a can improve the structural strength of the casing 1 and prevent the casing 1 from being deformed, resulting in uneven distance between the heating plate 5 and the casing 1, thereby causing the casing The amount of movement of the material in 1 is not uniform, which makes the drying of the material uneven, which affects the drying effect.
具体来说，所述加热盘5包括板体一5d和板体二5e，所述板体一5d和板体二5e均呈现圆环状，所述板体一5d和板体二5e之间焊接有圆环形的封板5f，所述板体一5d、板体二5e和主轴3的外壁焊接，所述板体一5d、板体二5e、封板5f和主轴3的外壁围成为所述蒸汽腔5h，所述主轴3上设置有若干个连接孔3d，所述主轴3上的加热盘5和相对应的主轴3上的连接孔3d一一对应，所述连接孔3d连通空腔3c和相对应的加热盘5中的蒸汽腔5h。Specifically, the heating plate 5 includes a plate body 5d and a plate body 5e, and the plate body 5d and the plate body 2e are both in the shape of a ring, and between the plate body 5d and the plate body 2e A circular sealing plate 5f is welded, the plate body 5d, the plate body 2e and the outer wall of the main shaft 3 are welded, and the outer wall of the plate body 5d, the plate body 2e, the sealing plate 5f and the main shaft 3 is welded. In the steam chamber 5h, the main shaft 3 is provided with a plurality of connecting holes 3d, and the heating plate 5 on the main shaft 3 and the connecting hole 3d on the corresponding main shaft 3 are in one-to-one correspondence, and the connecting holes 3d are connected to each other. The chamber 3c and the corresponding steam chamber 5h in the heating plate 5.
空腔3c中蒸汽通过连接孔3d进入到蒸汽腔5h中，蒸汽给加热盘5加热，增加物料的受热面积，提高干燥的效率，加热盘5和物料直接接触后蒸发掉物料中的水分，起到干燥物料的作用。The steam in the cavity 3c enters the steam chamber 5h through the connecting hole 3d, and the steam heats the heating plate 5, increases the heating area of the material, improves the drying efficiency, and evaporates the moisture in the material after the heating plate 5 and the material are in direct contact. To the role of dry materials.
具体来说，所述板体一5d和板体二5e之间还焊接有圆环形的连接板5g，所述连接板5g位于封板5f的外侧。Specifically, a circular connecting plate 5g is welded between the plate body 5d and the plate body 2e, and the connecting plate 5g is located outside the sealing plate 5f.
连接板5g起到保护封板5f、板体一5d和板体二5e之间的焊缝的作用，避免物料在沿着机壳1内壁移动的过程中，物料直接摩擦封板5f、板体一5d和板体二5e之间的焊缝，使得该焊缝发生磨损，而导致蒸汽腔5h中的蒸汽泄漏到机壳1中。The connecting plate 5g functions as a weld between the sealing plate 5f, the plate body 5d and the plate body 5e, and prevents the material from directly rubbing the sealing plate 5f and the plate body during the process of moving along the inner wall of the casing 1. The weld between a 5d and the plate body 5e causes the weld to wear, and the steam in the steam chamber 5h leaks into the casing 1.
具体来说，所述加热盘5中沿着径向焊接有隔板5b，隔板5b分别和板体一5d、板体二5e、封板5f和主轴3的外壁焊接，所述主轴3中设置有凝水排出装置，所述凝水排出装置包括汇总管9a和若干根排水管9，所述排水管9和加热盘5一一对应并且所述排水管9的一端和汇总管9a连通，另外一端和加热盘5的蒸汽腔5h连通，所述连接孔3d和排水管9分别位于隔板5b的两侧，所述排水管9和排水软管9b的一端连接，所述排水软管9b的另 外的一端穿过出气孔3a1和锅炉连通。Specifically, the heating plate 5 is welded with a partition plate 5b along the radial direction, and the partition plate 5b is welded to the outer wall of the plate body 5d, the plate body 2e, the sealing plate 5f and the main shaft 3, respectively. A condensate draining device is provided, the condensate draining device comprising a collecting pipe 9a and a plurality of drain pipes 9, the drain pipe 9 and the heating plate 5 are in one-to-one correspondence, and one end of the drain pipe 9 is connected to the collecting pipe 9a, The other end is in communication with the steam chamber 5h of the heating plate 5, the connecting hole 3d and the drain pipe 9 are respectively located on both sides of the partition 5b, and the drain pipe 9 is connected to one end of the drain hose 9b, and the drain hose 9b The other end is connected to the boiler through the air outlet 3a1.
蒸汽腔5h中的蒸汽遇冷以后会发生凝水，水体因为重力的作用会汇聚在加热盘5的底部，加热盘5转动时，隔板5b会跟随加热盘5一起转动，隔板5b可以把汇聚在加热盘5底部水体向上推起，使得水体可以通过排水管9进入到汇总管9a中，起到排放加热盘5中水体的作用。The steam in the steam chamber 5h will condense after the cold, and the water body will converge on the bottom of the heating plate 5 due to the action of gravity. When the heating plate 5 rotates, the partition plate 5b will rotate together with the heating plate 5, and the partition plate 5b can The water body is pushed up at the bottom of the heating plate 5 so that the water body can enter the collecting pipe 9a through the drain pipe 9 to discharge the water body in the heating plate 5.
具体来说，所述板体二5e的表面沿着周向均匀设置有若干个横截面呈圆形的冲击孔5c，所述冲击孔5c的边沿和板体一5d焊接固定，可以增强加热盘5的结构强度，防止加热盘5发生鼓包而使得直径较大的加热盘5和直径较小的加热盘5之间因为距离太小使得刮刀8无法通过而卡住，也可能因为直径较大的加热盘5和直径较小的加热盘5之间局部距离太近或者太远导致刮刀8受力异常，从而使得刮刀8不能正常刮除物料。Specifically, the surface of the plate body 2e is uniformly disposed with a plurality of impact holes 5c having a circular cross section along the circumferential direction, and the edge of the impact hole 5c is welded and fixed to the plate body 5d to enhance the heating plate. The structural strength of 5 prevents the heating plate 5 from being bulged, so that the diameter between the heating plate 5 having a larger diameter and the heating plate 5 having a smaller diameter is too small to cause the blade 8 to pass and may be stuck, or may be because of a larger diameter. A local distance between the heating plate 5 and the smaller diameter heating plate 5 is too close or too far, causing the blade 8 to be subjected to an abnormal force, so that the blade 8 cannot properly scrape the material.
另外因为冲击孔5c和板体一5d的焊缝位于冲击孔5c的底部，在工作的过程中，冲击孔5c中会填满物料，在刮刀8刮除物料的过程中，该焊缝不会和物料发生摩擦，从而起到保护焊缝的作用，避免焊缝磨损而导致蒸汽腔5h中的蒸汽泄漏到机壳1中。In addition, since the weld hole of the impact hole 5c and the plate body 5d is located at the bottom of the impact hole 5c, during the working process, the impact hole 5c is filled with material, and the weld seam is not in the process of scraping the material by the scraper 8. Friction with the material, thereby protecting the weld seam, preventing the weld from being worn and causing the steam in the steam chamber 5h to leak into the casing 1.
位于冲击孔5c中的物料会因为水分的蒸发自然的从冲击孔5c中脱落，并且冲击孔5c中的物料脱落后新的物料会再次填充到冲击孔5c中，不断的循环往复，始终可以起到保护焊缝的作用。The material located in the impingement hole 5c naturally falls off from the impingement hole 5c due to evaporation of moisture, and the new material in the impingement hole 5c is again filled into the impingement hole 5c, and the cycle is repeated. To protect the weld.
具体来说，所述刮刀8包括刮板8a、连接部8b和底座8c，所述刮板8a竖直设置并且一侧向机壳1的物料出口1c一侧倾斜，使得刮板8a随着加热盘5转动时可以把物料从机壳1的物料进口1b往物料出口1c输送，相对于螺旋输送叶片来说，结构简单，安装方便；Specifically, the scraper 8 includes a squeegee 8a, a connecting portion 8b, and a base 8c which are vertically disposed and which are inclined to the side of the material outlet 1c of the casing 1 at one side, so that the squeegee 8a is heated When the disc 5 rotates, the material can be transported from the material inlet 1b of the casing 1 to the material outlet 1c, and the structure is simple and convenient to install compared with the spiral conveying blade;
所述连接部8b固连在刮板8a的背面，所述底座8c竖直设置，所述连接部8b和底座8c可拆卸连接，便于更换刮板8a，所 述底座8c焊接在直径较小的加热盘5的边沿。The connecting portion 8b is fixed to the back surface of the squeegee 8a, the base 8c is vertically disposed, and the connecting portion 8b and the base 8c are detachably connected to facilitate replacement of the squeegee 8a, and the base 8c is welded to a small diameter.
