发明内容Summary of the invention
本发明的目的是提供一种浆料连续蒸发输送装置，使其可以方便地控制浆料粘度，可用于连续生产，且不需要另行设置输送泵。The purpose of the present invention is to provide a slurry continuous evaporation and conveying device, which can conveniently control the viscosity of the slurry, can be used for continuous production, and does not require a separate conveying pump.
本发明的目的是这样实现的：一种浆料连续蒸发输送装置，包括机架，机架上设有壳体，所述壳体由同轴线设置的圆柱形壳体和圆锥形壳体连接而成；圆锥形壳体的大径端直 径小于圆柱形壳体的直径，圆锥形壳体的大径一端连接在圆柱形壳体一端；圆柱形壳体顶部设有蒸汽出口，圆柱形壳体上还设有进料口，圆锥形壳体的小径端设有出料口；所述壳体内设有转子，转子两端分别经轴承转动支撑在机架上，所述转子包括转轴，转轴上连接有筒体，筒体在壳体内从一端延伸至另一端；筒体外设有螺旋推进叶片，与圆柱形壳体对应的螺旋推进叶片为带孔等径叶片，与圆锥形壳体对应的螺旋推进叶片为无孔缩径叶片；所述圆柱形壳体内在带孔等径叶片外周设有经由横向栅条和周向栅条组成的搅拌笼，搅拌笼的外周设有若干桨叶，桨叶的端部与圆柱形壳体内壁相匹配。The object of the present invention is achieved as follows: a slurry continuous evaporation and conveying device, including a frame, the frame is provided with a shell, and the shell is connected by a cylindrical shell and a conical shell arranged coaxially. The diameter of the large-diameter end of the conical shell is smaller than that of the cylindrical shell, and the large-diameter end of the conical shell is connected to one end of the cylindrical shell; the top of the cylindrical shell is provided with a steam outlet, the cylindrical shell A feed port is also provided on the conical shell, and the small diameter end of the conical shell is provided with a discharge port; the shell is provided with a rotor, and the two ends of the rotor are respectively rotatably supported on the frame through bearings. The rotor includes a rotating shaft. Connected to the cylinder, the cylinder extends from one end to the other end in the housing; the cylinder body is provided with spiral propelling blades, and the spiral propelling blades corresponding to the cylindrical shell are equal-diameter blades with holes, and the spiral corresponding to the conical shell The propelling blades are non-porous reduced-diameter blades; the cylindrical shell is provided with a stirring cage composed of a horizontal grid and a circumferential grid on the outer periphery of the perforated equal-diameter blades. The outer periphery of the stirring cage is provided with several paddles. The end of the cylinder matches the inner wall of the cylindrical shell.
本发明在使用时，蒸汽出口连接抽气装置，整个壳体内保持一定的真空度，热的浆液从进料口进入装置内，保持其料位不超过锥形壳体的1/3，最好是刚好接触到无孔缩径叶片或略高于无孔缩径叶的最下沿，通过外接动力输入，驱动转子转动，物料被浆液搅起，并接触到带孔推进叶片、搅拌笼和筒体，使得物料圆柱形壳体内形成抛洒、滴流、成线、拉膜等不同状态，物料自身的蒸发面积极度扩大，物料中的水分或小分子挥发物迅速被蒸发，自身粘度增大。当物料自身粘度较低时，液体从无孔缩径叶片与圆锥形筒体之间的间隙回流到圆柱形壳体内，无孔缩径叶片无法将低粘度的浆料输送至出料口，只有物料粘度较高时，由于髙粘度物料自身具有封闭间隙的能力，流动性差，才能被无孔缩径叶片推向出料口，因此，装置内通过从进料口控制料流大小及壳体内部的料位，即可控制出料口的浆料粘度，使得达到一定粘度的物料才能从出料口离开。与现有技术相比，本发明的有益效果在于：其可以方便地控制浆料粘度，其能够连续进料并连续出料，无孔缩径叶片具有增压输送功能，在低压输送给的情况下，可取代排料泵，因此不需要另行设置输送泵。该装置可以用于食品、药品、化纤生产中，作为蒸发器、浓缩器、反应器使用。When the present invention is in use, the steam outlet is connected to the air extraction device, a certain degree of vacuum is maintained in the whole shell, and the hot slurry enters the device from the feed port to keep the material level not exceeding 1/3 of the conical shell, preferably It is just touching the bottom edge of the non-porous reduced diameter blade or slightly higher than the lowest edge of the non-porous reduced diameter blade. Through external power input, the rotor is driven to rotate, and the material is stirred by the slurry and touches the perforated propeller blade, mixing cage and drum The body makes the material form different states such as throwing, trickling, threading, film drawing, etc. in the cylindrical shell of the material. The evaporation surface of the material itself expands, the water or small molecule volatiles in the material are quickly evaporated, and its own viscosity increases. When the viscosity of the material itself is low, the liquid flows back into the cylindrical shell from the gap between the non-porous reduced diameter blade and the conical cylinder. The non-porous reduced diameter blade cannot transport the low-viscosity slurry to the discharge port. When the material viscosity is high, because the high viscosity material has the ability to close the gap and the fluidity is poor, it can be pushed to the discharge port by the non-porous reduced diameter blade. Therefore, the device controls the flow of the material and the inside of the shell from the feed port. The material level can control the viscosity of the slurry at the discharge port, so that the material that reaches a certain viscosity can leave the discharge port. Compared with the prior art, the beneficial effects of the present invention are: it can conveniently control the viscosity of the slurry, it can continuously feed and discharge the material, the non-porous reduced diameter blade has the function of pressurizing and conveying, and in the case of low pressure conveying It can replace the discharge pump, so there is no need to set up a delivery pump. The device can be used in the production of food, medicine, and chemical fiber, as an evaporator, concentrator, and reactor.
其进一步改进在于，所述搅拌笼两端经带孔端板或辐条连接在筒体外周。该方案实施简单。The further improvement lies in that the two ends of the stirring cage are connected to the outer circumference of the cylinder via perforated end plates or spokes. The program is simple to implement.
其进一步改进在于，所述筒体外设有加热装置。由于物料蒸发过程中需要吸收大量的汽化潜热，通过加热装置可以促进其蒸发浓缩。优选方案是所述加热装置设置在筒体底部。由于物料处于半充满状态，设置在底部的加热装置更容易对物料进行加热。A further improvement is that a heating device is provided outside the barrel. As the material needs to absorb a large amount of latent heat of vaporization during the evaporation process, the heating device can promote its evaporation and concentration. The preferred solution is that the heating device is arranged at the bottom of the cylinder. Since the material is half-filled, the heating device at the bottom is easier to heat the material.
其进一步改进在于，所述进料口设置在远离出料口的圆柱形壳体的端部下侧。进料口设置在远离出料口的位置，使得进料和出料之间可以形成粘度呈梯度分布的状态，具有一定的粘度的物料，流动性差，进料口位置的物料流动到出料口需要一段时间，物料尽管在装置内不断被搅拌，但这种搅拌并不会改变粘度的分布趋势，所有进入装置内的物料都是缓慢从进料口向出料口移动，期间获得的蒸发机会均等，可以实现均匀出料、稳定生产的效果。A further improvement is that the feed port is arranged on the lower side of the end of the cylindrical shell away from the discharge port. The feed port is set far away from the discharge port, so that a state with a gradient distribution of viscosity can be formed between the feed and the discharge. The material with a certain viscosity has poor fluidity, and the material at the feed port flows to the discharge port. It takes a period of time. Although the materials are continuously stirred in the device, this stirring does not change the viscosity distribution trend. All the materials entering the device are slowly moved from the inlet to the outlet, and the evaporation opportunities are obtained during the period. Equal, can realize the effect of uniform discharging and stable production.
其进一步改进在于，所述蒸汽出口连接真空泵，蒸汽出口压力为0.01～0.1MPa。根据不同生产需求，可以对蒸汽压力进行调整。The further improvement is that the steam outlet is connected to a vacuum pump, and the pressure of the steam outlet is 0.01-0.1 MPa. According to different production requirements, the steam pressure can be adjusted.
其进一步改进在于，所述蒸汽出口与壳体之间设有集汽箱。通过集汽箱缓冲，可以帮助蒸汽中夹带的物料沉降，避免蒸汽夹带物料，影响装置的效率，同时，避免堵塞真空抽气装置。Its further improvement lies in that a steam collecting box is arranged between the steam outlet and the shell. The buffer of the steam collecting box can help the material entrained in the steam settle, avoid the material entrained by the steam, and affect the efficiency of the device, and at the same time, avoid blocking the vacuum pumping device.
其进一步改进在于，所述桨叶的推进面与筒体的法向平面之间的夹角在±15°之间。通过不同角度的设置，可以帮助物料进行搅拌或改变物料在装置内的停留时间，从而获得不同的蒸发机会，可根据物料特性进行角度选择，这一角度可以是固定的。进一步地，所述桨叶角度可调，这样可以随时改变浆叶的推进角度。The further improvement is that the angle between the propulsion surface of the blade and the normal plane of the cylinder is between ±15°. Through the setting of different angles, it can help the material to stir or change the residence time of the material in the device, so as to obtain different evaporation opportunities. The angle can be selected according to the characteristics of the material, and this angle can be fixed. Further, the angle of the blade is adjustable, so that the advancing angle of the blade can be changed at any time.

The diameter of the large-diameter end of the conical shell 13 is smaller than the diameter of the cylindrical shell 10, and the large-diameter end of the conical shell 13 is connected to one end of the cylindrical shell 10; the top of the cylindrical shell 10 is provided with a steam outlet 6 , The steam outlet 6 can be connected to a vacuum pump. The cylindrical shell 10 is also provided with a feed port 21, and the small diameter end of the conical shell 13 is provided with a discharge port 16; the shell is provided with a rotor, and the two ends of the rotor are rotatably supported by the left bearing 4 and the right bearing 15 respectively. On the frame 17, the rotor includes a rotating shaft 5. One end of the rotating shaft 5 is provided with a coupling 3 through which power can be input. The rotating shaft 5 is connected with a cylinder 2 which extends from one end to the other in the housing. One end; the cylinder 2 is provided with a spiral propeller blade, and the spiral propeller blade corresponding to the cylindrical shell 10 is a perforated equal diameter blade 11, and the perforated equal diameter blade 11 is provided with a number of plate holes 22, and a conical shell 13 The corresponding spiral propeller blade is a non-porous reduced-diameter blade 14; in the cylindrical casing 10, a stirring cage 9 composed of a horizontal grid 1 and a circumferential grid 12 is provided on the outer periphery of the perforated equal-diameter blade 11. A number of paddles 8 are provided on the outer periphery, and the ends of the paddles 8 match the inner wall of the cylindrical housing 10. The bottom of the cylindrical shell 10 is also provided with an emptying port 19.
搅拌笼9两端经带孔端板18或辐条连接在筒体2外周。本实施例中采用的是带孔端板18，可以很好地支撑搅拌笼9，形成更大的比表面积，同时不会过分阻挡物料的流动。The two ends of the stirring cage 9 are connected to the outer circumference of the cylinder 2 via the perforated end plates 18 or spokes. In this embodiment, a perforated end plate 18 is used, which can support the stirring cage 9 well and form a larger specific surface area without excessively blocking the flow of materials.
筒体2外设有加热装置20，加热装置20可以通过蒸汽加热、导热油加热或电加热。由于物料蒸发过程中需要吸收大量的汽化潜热，通过加热装置20可以促进其蒸发浓缩。优选方案是加热装置20设置在筒体2底部。由于物料处于半充满状态，设置在底部的加热装置20更容易对物料进行加热。A heating device 20 is provided outside the barrel 2, and the heating device 20 can be heated by steam, heat conduction oil or electric heating. Since the material needs to absorb a large amount of latent heat of vaporization during the evaporation process, the heating device 20 can promote its evaporation and concentration. The preferred solution is that the heating device 20 is arranged at the bottom of the cylinder 2. Since the material is in a semi-full state, the heating device 20 arranged at the bottom is easier to heat the material.
进料口21设置在远离出料口16的圆柱形壳体10的端部下侧。进料口21设置在远离出料口16的位置，使得进料和出料之间可以形成粘度呈梯度分布的状态，具有一定的粘度的物料，流动性差，进料口21位置的物料流动到出料口16需要一段时间，物料尽管在装置内不断被搅拌，但这种搅拌并不会改变粘度的分布趋势，所有进入装置内的物料都是缓慢从进料口21向出料口16移动，期间获得的蒸发机会均等，可以实现均匀出料、稳定生产的效果。The feed port 21 is provided on the lower side of the end of the cylindrical housing 10 away from the discharge port 16. The feed port 21 is arranged at a position far away from the discharge port 16, so that a state of a gradient distribution of viscosity can be formed between the feed and the discharge. The material with a certain viscosity has poor fluidity, and the material at the position of the feed port 21 flows to The discharge port 16 takes a period of time. Although the materials are continuously stirred in the device, this stirring does not change the viscosity distribution trend. All the materials entering the device move slowly from the feed port 21 to the discharge port 16. , The evaporation opportunities obtained during the period are equal, and the effect of uniform discharge and stable production can be achieved.
蒸汽出口6与壳体之间设有集汽箱7。通过集汽箱7缓冲，可以帮助蒸汽中夹带的物料沉降，避免蒸汽夹带物料，影响装置的效率，同时，避免堵塞真空抽气装置。A steam collecting box 7 is provided between the steam outlet 6 and the shell. The buffer of the steam collecting box 7 can help the material entrained in the steam settle, avoid the material entrained by the steam, and affect the efficiency of the device, and at the same time, avoid blocking the vacuum pumping device.
桨叶8的推进面与筒体2的法向平面之间的夹角控制在±15°之间。通过不同角度的设置，可以帮助物料进行搅拌或改变物料在装置内的停留时间，从而获得不同的蒸发机会，可根据物料特性进行角度选择，这一角度可以是固定的。进一步地，桨叶8角度可调，这样可以随时改变浆叶的推进角度。The angle between the propulsion surface of the blade 8 and the normal plane of the cylinder 2 is controlled to be between ±15°. Through the setting of different angles, it can help the material to stir or change the residence time of the material in the device, so as to obtain different evaporation opportunities. The angle can be selected according to the characteristics of the material, and this angle can be fixed. Further, the angle of the blade 8 is adjustable, so that the advancing angle of the blade can be changed at any time.
在使用时，蒸汽出口6连接抽气装置，生产中控制蒸汽出口6压力为0.01～0.1MPa，热的浆液从进料口21进入装置内，保持其料位不超过锥形壳体的1/3，最好是刚好接触到无孔缩径叶片14或略高于无孔缩径叶的最下沿，通过外接动力输入，驱动转子转动，物料被浆液搅起，并接触到带孔推进叶片、搅拌笼9和筒体2，使得物料圆柱形壳体10内形成抛洒、滴流、成线、拉膜等不同状态，物料自身的蒸发面积极度扩大，物料中的水分或小分子挥发物迅速被蒸发，自身粘度增大。当物料自身粘度较低时，液体从无孔缩径叶片14与圆锥形筒体2之间的间隙回流到圆柱形壳体10内，无孔缩径叶片14无法将低粘度的浆料输送至出料口16，只有物料粘度较高时，由于髙粘度物料自身具有封闭间隙的能力，流动性差，才能被无孔缩径叶片14推向出料口16，因此，装置内通过从进料口21控制料流大小及壳体内部的料位，即可控制出料口16的浆料粘度，使得达到一定粘度的物料才能从出料口16离开。该装置可以方便地控制浆料粘度，其能够连续进料并连续出料，无孔缩径叶片14具有增压输送功能，在低压输送给的情况下，可取代排料泵，因此不需要另行设置输送泵。该 装置可以用于食品、药品、化纤生产中，作为蒸发器、浓缩器、反应器使用。When in use, the steam outlet 6 is connected to the air extraction device. During production, the pressure of the steam outlet 6 is controlled to be 0.01～0.1MPa, and the hot slurry enters the device from the inlet 21 to keep its material level not exceeding 1/ of the conical shell. 3. It is best to just touch the non-porous reduced diameter blade 14 or slightly higher than the bottom edge of the non-porous reduced diameter blade. Through an external power input, the rotor is driven to rotate, and the material is stirred by the slurry and touches the perforated propelling blade , Stirring cage 9 and cylinder 2, make the material in the cylindrical shell 10 form different states such as throwing, trickling, threading, film drawing, etc., the evaporation surface of the material itself expands, and the moisture or small molecule volatiles in the material are rapidly Being evaporated, its own viscosity increases. When the viscosity of the material itself is low, the liquid flows back into the cylindrical shell 10 from the gap between the non-porous diameter-reducing blade 14 and the conical cylinder 2, and the non-porous diameter-reducing blade 14 cannot transport the low-viscosity slurry to The discharge port 16, only when the material viscosity is high, because the high viscosity material has the ability to close the gap and the fluidity is poor, it can be pushed to the discharge port 16 by the non-porous reduced diameter blade 14. Therefore, the device passes through the feed port 21. By controlling the size of the material flow and the material level inside the shell, the viscosity of the slurry at the discharge port 16 can be controlled, so that the material that reaches a certain viscosity can leave the discharge port 16. The device can easily control the viscosity of the slurry. It can continuously feed and discharge the material. The non-porous reduced diameter blade 14 has the function of pressurizing and conveying. In the case of low pressure conveying, it can replace the discharge pump, so no additional Set up the delivery pump. The device can be used in the production of food, medicine, and chemical fiber, as an evaporator, concentrator, and reactor.
