DETAILED DESCRIPTION

[0018] The technical solutions will be further described below in combination with specific embodiments, and it should be noted that the words such as up and down in the text only refer to the positions of the shown structures in the corresponding drawings. The serial numbers of the components in the text, such as first, second, etc., are only used to distinguish the described objects and do not have any sequence or technical meaning. The connection in the present application includes direct and indirect connection, unless otherwise specified.

[0019] To solve the problem that the transmission fixed angle guide baffle and baffle are difficult to consider different viscosity materials, which restricts the applicability and operation stability of the scraper evaporator in complex wastewater treatment, the present application is described as follows (in the present application, "wastewater" is referred to as "material"): Example 1

[0020] An intelligent scraper evaporator, such as Figures 1-8As shown, it comprises a heating cylinder 1, a discharge shell 2 connected to the lower side of the heating cylinder 1, a first connecting shell 3 connected to the upper side of the heating cylinder 1, a second connecting shell 4 connected to the upper side of the first connecting shell 3, a feeding pipe 5 connected to the first connecting shell 3 and connected to the second connecting shell 4, the feeding pipe 5 is symmetrically distributed in the device, in actual use, the number can be adjusted according to the situation, an exhaust pipe 6 connected to the second connecting shell 4, a viscosity detection module (not shown in the figure, which is an existing mechanism, used to detect the viscosity of the liquid) arranged in the exhaust pipe 6, a cover plate 7 connected to the upper side of the second connecting shell 4, a scraping assembly arranged in the heating cylinder 1 for scraping the material to the inner wall thereof, a first fixed plate 11 connected to the upper side of the first connecting shell 3, a first rotating baffle 12 arranged in the first connecting shell 3 in an annular array, a fixed pipe 13 arranged in an annular array and connected to the first fixed plate 11, the upper and lower parts of the fixed pipe 13 are respectively connected to the second connecting shell 4 and the first connecting shell 3, the fixed pipe 13 arranged in an annular array is collectively connected to a first fixed ring 14 located below the first fixed plate 11, the first rotating baffle 12 is composed of an arc plate and a cylinder which are connected to each other, the inner and outer sides of the arc plate are respectively in contact with the first connecting shell 3 and the first fixed ring 14, there is a gap between the first connecting shell 3 and the first fixed ring 14, the opposite sides of the first rotating baffle 12 arranged in an annular array are in contact with the first fixed ring 14, the lower side of the first fixed ring 14 is connected to a second fixed plate 15, the second connecting shell 4 is sealingly connected to a second rotating baffle 16 arranged in an annular array, the second rotating baffle 16 is composed of a sector plate and a circular rod which are connected to each other, the sector plate is in contact with the inner side of the second rotating baffle 16; The projections of the adjacent two second rotating baffles 16 on the horizontal plane intersect, the cover plate 7 is connected to a first fixed table 701 located in the second connecting shell 4, the opposite sides of the second rotating baffle 16 arranged in an annular array are rotatably connected to the first fixed table 701; The inner middle part of the first connecting shell 3, the outer side of the first fixed ring 14 and the inner middle part of the second connecting shell 4 are annular arc surfaces, and the centers of the spheres corresponding to the annular arc surfaces of the first connecting shell 3 and the first fixed ring 14 are concentric, all the first rotating baffles 12 are always attached to the annular arc surfaces of the first fixed ring 14 and the first connecting shell 3, and the back sides of all the second rotating baffles 16 are attached to the annular arc surface of the second connecting shell 4, the gap between the first connecting shell 3 and the first fixed ring 14 is annular, and the cross section of the annular gap is C-shaped.

[0021] In the above scheme, the steam is blocked under the action of the intersection of the projections of the two adjacent second rotating baffles 16 on the horizontal plane, the viscosity of the material transported by the feed pipe 5 is detected by the viscosity detection module (through this sensing method, the swing angle of all first rotating baffles 12 and all second rotating baffles 16 is adjusted in time according to the viscosity of the material, thereby realizing intelligent effect), and then the swing angle of all first rotating baffles 12 and all second rotating baffles 16 is adjusted. When encountering high-viscosity material, the swing angle of all first rotating baffles 12 and all second rotating baffles 16 is increased, the gap between the two adjacent first rotating baffles 12 and the gap between the two adjacent second rotating baffles 16 are increased, the resistance when the steam is discharged is reduced, thereby reducing the back pressure, preventing the delay of feeding due to the excessive pressure in the first connecting shell 3, and ensuring the smoothness of material supply by increasing the swing angle of all first rotating baffles 12. When encountering low-viscosity material, the swing angle of all first rotating baffles 12 and all second rotating baffles 16 is reduced, the gap between the two adjacent first rotating baffles 12 and the gap between the two adjacent second rotating baffles 16 are reduced, the resistance when the steam is discharged is increased, the pressure in the first connecting shell 3 is increased, and part of the material is prevented from being directly discharged without evaporation. All second rotating baffles 16 together form a gas-liquid separator. When steam with liquid droplets hits the lower side of all second rotating baffles 16, due to the large mass and strong inertia of the liquid droplets, they cannot quickly turn with the gas, so they will deviate from the gas flow trajectory and hit the lower side of all second rotating baffles 16. The liquid droplets adhere and gather into large droplets, which flow along all second rotating baffles 16 to the inner wall of the second connecting shell 4 under the action of gravity and slide freely along the inner wall.

[0022] As shown in Figure 1 and Figure 2 , the scraping assembly includes a motor 8 arranged on the cover plate 7. The motor 8 is fixedly connected with a rotating rod 9 which is rotationally connected with the cover plate 7, the first fixed plate 11 and the second fixed plate 15. The lower part of the rotating rod 9 is fixedly connected with a plurality of scrapers 10 which are in contact with the inner wall of the heating cylinder 1.

[0023] As shown in Figures 6-8 , the annular curved surface of the first connecting shell 3 and the connecting part at the lower part thereof form a smooth curved surface. The smooth curved surface is used to guide the material on the inner wall of the first connecting shell 3 to the inner wall of the heating cylinder 1.

[0024] In the above scheme, the material first contacts the inner wall of the heating cylinder 1, preventing the material from directly falling freely into the heating cylinder 1 and delaying the evaporation of the water in the material.

[0025] As shown in Figures 3-5 and Figure 9As shown, the heating cylinder 1 is fixed with an electric push rod 20, the telescopic end of the electric push rod 20 is fixed with two sliding rings 21, the sliding rings 21 are internally spherical with a telescopic frame 22 arranged in an annular array, the telescopic frame 22 close to the second connecting shell 4 is in one-to-one correspondence with the second rotating baffle 16 and the two are fixed with each other, and the telescopic frame 22 close to the first connecting shell 3 is in one-to-one correspondence with the first rotating baffle 12 and the two are fixed with each other.

[0026] In the above scheme, when the two sliding rings 21 move upward or downward, the telescopic part of all telescopic frames 22 contracts or stretches to drive the corresponding second rotating baffle 16 or first rotating baffle 12 to rotate, thereby reducing or increasing the gap between the two adjacent first rotating baffles 12 and the gap between the two adjacent second rotating baffles 16.

[0027] As shown in the figure, Figures 6-8 The second fixed plate 15 is fixed with a second fixed ring 23, and a gap is left between the second fixed ring 23 and the first fixed plate 11, the first fixed plate 11 is fixed with a third fixed ring 24, and a gap is left between the third fixed ring 24 and the second fixed plate 15, and a gap is left between the first fixed ring 14 and the first fixed plate 11.

[0028] In the above scheme, the diameter of the second fixed ring 23 is smaller than the diameter of the third fixed ring 24, the fixed tube 13, the first fixed ring 14 and the second fixed plate 15 are all heat-conducting materials, the steam contacts the second fixed plate 15 to heat it, the second fixed plate 15 preheats the material on its upper side, and the serpentine guide formed by the second fixed ring 23, the third fixed ring 24 and the first fixed ring 14 makes the material change direction and extend the flow path multiple times before entering the heating cylinder 1, thereby reducing the viscosity difference of the material entering the heating cylinder 1 and improving the preheating efficiency of the material.

[0029] As shown in the figure, Figures 6-8 The edge of the lower side of the second fixed plate 15 is fixed with a guide ring 25, the cross section of the guide ring 25 is V-shaped, and the guide ring 25 is used to guide the material outside the first fixed ring 14.

[0030] In the above scheme, the material outside the first fixed ring 14 is guided by the guide ring 25 to the inner wall of the first connecting shell 3, so that the material flows downward along the inner wall of the first connecting shell 3, and the steam is guided inside the guide ring 25 to enter the fixed tube 13.

[0031] As shown in the figure, Figure 8 The lower side of the second fixed plate 15 is fixed with a second fixed table 26, the rotating rod 9 is rotatably connected with the second fixed table 26, and the lower side of the second fixed table 26 is provided with an annular inclined surface for guiding the steam.

[0032] In the above scheme, the second fixed table 26 is made of heat-conducting material. The annular inclined surface of the second fixed table 26 guides the steam to enter all the fixed pipes 13 between the guide ring 25 and the second fixed table 26.

[0033] Working principle: when the material needs to be processed, the external heating part increases the temperature of the heating cylinder 1, at the same time, the motor 8 drives the rotating rod 9 to rotate, the rotating rod 9 drives all the scrapers 10 to rotate in the heating cylinder 1, the hot gas in the heating cylinder 1 flows upward and is transported into the second connecting shell 4 by the fixed pipe 13, the hot gas then flows upward through the gap between all the second rotating baffles 16 and is discharged by the air outlet pipe 6 (in the process of use, an external air extraction device can be connected with the air outlet pipe 6), in this process, the second fixed plate 15 is heated, preparing for the subsequent preheating of the material.

[0034] When the preheating is completed, the material enters the upper side of the second fixed plate 15 through the feeding pipe 5, in this process, the viscosity of the material is detected by the viscosity detection module, as the material is added, when the liquid surface of the material is higher than the upper side of the second fixed ring 23, the material enters between the second fixed ring 23 and the third fixed ring 24 through the gap between the second fixed ring 23 and the first fixed plate 11, then enters between the third fixed ring 24 and the first fixed plate 11 through the gap between the third fixed ring 24 and the second fixed plate 15, as the liquid surface of the material between the two rises, the material enters the C-shaped cavity composed of the first fixed ring 14 and the first connecting shell 3 through the gap between the first fixed ring 14 and the first fixed plate 11, then falls freely, the serpentine guide formed by the above working principle makes the material change direction and extend the flow path multiple times before entering the heating cylinder 1, so as to improve the preheating efficiency of the material, at the same time, the motor 8 drives the rotating rod 9 and all the scrapers 10 to rotate, through the rotation of the scrapers 10, the material is scraped to the inner wall of the heating cylinder 1, so that the water in the material is evaporated, and then moves upward in the form of steam, and the material with removed water is discharged from the discharge shell 2.

[0035] The steam enters the fixed pipe 13 under the guidance of the second fixed table 26 and the guide ring 25, and is transported into the second connecting shell 4 by the fixed pipe 13, then flows upward through the gap between all the second rotating baffles 16 and is discharged by the air outlet pipe 6.

[0036] When the viscosity detection module in the feed pipe 5 senses that the viscosity of the material is high, the telescopic end of the electric push rod 20 drives the two sliding rings 21 to move upwards, the sliding rings 21 drive the lower sides of all telescopic frames 22 to move upwards, so that the telescopic part of the telescopic frame 22 drives the first rotating baffle 12 or the second rotating baffle 16 to rotate in the process of retraction, so that all the first rotating baffles 12 and the second rotating baffles 16 tend to be vertical, the resistance when the steam is discharged is reduced through all the second rotating baffles 16, thereby reducing the back pressure, and the degree of obstruction to the material is reduced through all the first rotating baffles 12, to ensure the smoothness of the material supply.

[0037] When the viscosity detection module in the feed pipe 5 senses that the viscosity of the material is low, the telescopic end of the electric push rod 20 drives the two sliding rings 21 to move downwards, the sliding rings 21 drive the lower sides of all telescopic frames 22 to move downwards, so that the telescopic part of the telescopic frame 22 drives the first rotating baffle 12 or the second rotating baffle 16 to rotate in the process of retraction, so that all the first rotating baffles 12 and the second rotating baffles 16 tend to be horizontal, the resistance when the steam is discharged is increased through all the second rotating baffles 16, the pressure in the first connecting shell 3 is increased, the degree of obstruction to the material is increased through all the first rotating baffles 12, and part of the material is prevented from being directly discharged without evaporation. Example 2

[0038] On the basis of example 1, as shown in Figure 7 , Figure 8 and Figure 10 , the first fixed plate 11 is fixedly connected with a guide table 27 located in the second connecting shell 4, the fixed pipe 13 is fixedly connected with the guide table 27, the upper side of the guide table 27 is recessed downward, the rotating rod 9 is rotationally connected with the guide table 27, the fixed pipe 13 is L-shaped, the lower side of the upper part of the fixed pipe 13 is provided with a gas outlet hole 28 for communicating the fixed pipe 13 with the second connecting shell 4, the lower side of the upper part of the fixed pipe 13 is fixedly connected with a shielding shell 29, the lower side of the shielding shell 29 is fixedly connected with a plurality of guide plates 30, the lower part of the guide plate 30 is sharp-shaped for guiding liquid drops, the rotating rod 9 is provided with a liquid guiding cavity 901 in communication with the heating cylinder 1, the liquid guiding cavity 901 is in communication with the second connecting shell 4, and the guide table 27 is used for conveying liquid drops into the liquid guiding cavity 901.

[0039] In the above scheme, the steam in the heating cylinder 1 is guided by the fixed pipe 13 and discharged through the gas outlet hole 28 on the lower side of the upper part of the fixed pipe 13, which prevents liquid drops from falling into the fixed pipe 13 and affecting the discharge of steam. The sharp-shaped lower part of the guide plate 30 guides the liquid drops, promotes the falling of the liquid drops, and the liquid drops fall into the liquid guiding cavity 901 when they fall into the recessed part of the guide table 27, and then directly fall into the lower part of the heating cylinder 1 from the lower side of the liquid guiding cavity 901. Since the steam will carry part of the material, this way is used to guide part of the material carried in the steam to reduce the loss of products.

[0040] Working principle: the steam in the heating cylinder 1 enters the fixed tube 13 in the process of moving upward, and is discharged from the air outlet hole 28 at the lower side of the upper part of the fixed tube 13, when the steam with liquid droplets hits the lower side of all the second rotating baffles 16, the liquid droplets cannot quickly turn with the gas under the action of their own heavy weight and strong inertia, so they will deviate from the gas flow trajectory and hit the lower side of all the second rotating baffles 16, and the liquid droplets will be attached and gathered into large liquid droplets, part of the liquid droplets will flow along all the second rotating baffles 16 to the inner wall of the second connecting shell 4 under the action of gravity, and slide along the inner wall to the upper side of the guide table 27, and the other part of the liquid droplets will fall to the upper side of the fixed tube 13, then be guided to the guide plate 30 by the shielding shell 29, and be guided by the guide plate 30, the liquid droplets falling into the recesses of the guide table 27 enter the liquid guiding cavity 901, and directly fall into the lower part of the heating cylinder 1 from the lower side of the liquid guiding cavity 901, so that the liquid droplets are discharged from the discharge shell 2 together with the material, and the above working principle realizes the prevention of the liquid droplets from falling into the fixed tube 13, so as to affect the discharge of the steam, and promotes the falling of the liquid droplets under the action of the sharp spikes at the lower part of the guide plate 30.

[0041] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
