DETAILED DESCRIPTION

[0026] The following combination Figure 1-Figure 6 This application is described in further detail.

[0027] Embodiment 1: The present application embodiment discloses a water homogenizer for a falling film thin film evaporation device. Figure 1 and Figure 2 The water homogenizer for the falling film evaporation device includes a distribution part and a water homogenizer. Both the distribution part and the water homogenizer are installed on the top of the thin film evaporation device. The distribution part is located above the water homogenizer. Specifically, the distribution part is connected to the liquid inlet pipe of the thin film evaporation device, so that the feed liquid is added to the water homogenizer from the liquid inlet pipe at the top of the thin film evaporation device through the pump body.

[0028] Reference Figure 2 The water-distributing part includes a plurality of water-distributing strips 1, which are made of inorganic or organic materials, and the materials are not limited to PP, PE, PS, PA, PSE, PTFE, iron, stainless steel, aluminum, titanium, gold, silver, fiberglass, graphite, silicon carbide and other materials; it has the advantages of good corrosion resistance, low cost, easy material availability and high practicality. The plurality of water-distributing strips 1 are arranged in sequence along the horizontal direction, and the adjacent water-distributing strips 1 are mutually abutted, so that the plurality of water-distributing strips 1 can form a plane, wherein the length direction of the water-distributing strips 1 is perpendicular to the arrangement direction of the plurality of water-distributing strips 1; the distribution part is arranged above the plane formed by the plurality of water-distributing strips 1, and the adjacent water-distributing strips 1 are used to clamp the upper end of the film, and the film is made of a polymer film; the water-distributing strips 1 are provided with a plurality of water-distributing holes 2, and the water-distributing holes 2 penetrate the water-distributing strips 1 from top to bottom, and the distribution part is used to guide the slurry to the plurality of water-distributing strips 1.

[0029] When in use, the feed liquid enters the distribution part from the liquid inlet pipe at the top of the thin film evaporation device through the pump body, and is introduced into the multiple water equalizing strips 1 below through the distribution part. The feed liquid flows along the water equalizing holes 2 on the water equalizing strips 1. Since the upper end of the film is clamped between adjacent water equalizing strips 1, the feed liquid flowing out of the multiple water equalizing holes 2 on the water equalizing strips 1 will flow along the outer walls of the adjacent two sides of the film to form a film, thereby helping to achieve uniform flow of the feed liquid along the outer wall of each film, greatly improving the water equalization effect.

[0030] Reference Figure 1 and Figure 2 In order to facilitate the liquid entering the liquid inlet pipeline to be directed to the multiple water-distributing strips 1, the distribution member includes a distribution box 3, which is installed at the upper end of the thin film evaporation device. The cross section of the distribution box 3 is rectangular. The distribution box 3 is located above the multiple water-distributing strips 1 and there is a certain gap between the bottom wall and the multiple water-distributing strips 1. The distribution box 3 is connected to the liquid inlet pipeline of the thin film evaporation device. The bottom wall of the distribution box 3 is provided with multiple water holes 4, through which the liquid is uniformly leaked to the plane of the water-distributing strip 1. Among them, the water holes 4 are fine holes, and the diameter size is set according to the needs, so that the liquid entering the distribution box 3 can be uniformly entered into the water-distributing holes 2 of the multiple water-distributing strips 1 along the multiple water holes 4, and will not flow out quickly from individual water holes 4.

[0031] When the liquid in the liquid inlet pipe enters the distribution box 3, it will enter the water equalizing holes 2 on the water equalizing strip 1 below through the multiple water holes 4 at the bottom of the distribution box 3, thereby achieving uniform introduction of the liquid into the water equalizing holes 2 on the water equalizing strip 1.

[0032] Reference Figure 2 and Figure 3 Specifically, each water-distributing strip 1 includes two water-distributing half strips 11 spliced ​​with each other, and a plurality of fins 5 are integrally formed on one side of the two water-distributing half strips 11 close to each other. The plurality of fins 5 are arranged at intervals along the length direction of the water-distributing half strips 11, wherein the plurality of fins 5 on the two water-distributing half strips 11 are abutted against each other in pairs to form a plurality of water-distributing holes 2. The two water-distributing half strips 11 of each water-distributing strip 1 are spliced ​​with hidden buckles, and the assembly is convenient.

[0033] Reference Figure 2 and Figure 3 Each water-distributing half-strip 11 includes a plurality of strip bodies 111, which are spliced ​​in sequence along their own length direction, so that the number of strip bodies 111 can be increased or decreased according to working conditions; a plurality of fins 5 are integrally formed on the strip body 111, and the plurality of fins 5 are spaced apart along the length direction of the strip body 111, and the corresponding two strip bodies 111 in the water-distributing half-strip 11 on both sides are spliced ​​by hidden buckles, thereby assembling into a water-distributing strip 1.

[0034] Reference Figure 2 and Figure 3 Specifically, a male buckle 15 is integrally formed on the strip body 111 on one side of the two water-distributing half strips 11 spliced ​​together, and a female buckle 16 is integrally formed on the strip body 111 on the other side. The two water-distributing half strips 11 are assembled by mutually buckling and cooperating with the male buckle 15 and the female buckle 16 between the strip bodies 111 in the two water-distributing half strips 11. The male buckle 15 and the female buckle 16 are both made of plastic, and have a certain connection strength after being buckled together. The assembly is easy and the sealing performance after assembly is good.

[0035] Reference Figure 2 and Figure 3 In order to facilitate the splicing between adjacent strips 111, both ends of the strips 111 in the length direction are integrally formed with mounting ends (not shown in the figure). When the male buckle 15 and the female buckle 16 on the two water-distributing half strips 11 are buckled and matched with each other, the mounting ends of the corresponding strips 111 on the two water-distributing half strips 11 abut against each other to prevent the liquid from flowing out. A splicing piece 6 is integrally formed on the mounting ends at both ends of the strip body 111. The splicing piece 6 includes two split pieces 61 integrally formed on the mounting ends of the strip body 111. There is a certain gap between the two split pieces 61 of the splicing piece 6. A splicing protrusion 7 is integrally formed on one split piece 61 of the splicing piece 6. A splicing hole 8 is provided on the other split piece 61. The splicing protrusion 7 is used to snap together with the splicing hole 8 on the splicing piece 6 of the adjacent strip body 111. The splicing hole 8 is used to snap together with the splicing protrusion 7 on the splicing piece 6 of the adjacent strip body 111. The splicing protrusions 7 on the splicing pieces 6 at both ends of the strip body 111 are diagonally arranged.

[0036] When adjacent strips 111 are spliced ​​together, the splicing protrusion 7 on the slice 61 at one end of the strip 111 is buckled with the splicing hole 8 on the slice 61 of the adjacent strip 111, and the splicing hole 8 on the other slice 61 is buckled with the splicing protrusion 7 on the slice 61 of the adjacent strip 111, so as to realize the splicing of adjacent strips 111, so that the strips 111 can be spliced ​​as needed to realize different lengths of the water-averaging half-strip 11, which is simple and convenient and has a wide range of applications.

[0037] Reference Figure 3 The splicing protrusions 7 are all located on the side of the corresponding slices 61 close to the fin 5, so that when adjacent strips 111 are spliced, the two slices 61 of the splicing sheet 6 are staggered with the two slices 61 of the splicing sheet 6 on the adjacent strips 111, that is, one slice 61 on one side of the strip 111 is located on the side of the slice 61 in the adjacent strip 111 close to the fin 5, and the other slice 61 is located on the side of the slice 61 in the adjacent strip 111 away from the fin 5. The cross-buckle connection helps to improve the splicing strength between the adjacent strips 111.

[0038] Reference Figure 1 and Figure 2 A screw rod 9 is commonly provided on multiple water-distributing strips 1, and multiple screw rods 9 are arranged at intervals along the length direction of the water-distributing strips 1, which helps to improve the connection strength of the multiple water-distributing strips 1; a through hole (not shown in the figure) for the screw rod 9 to pass through is opened on the strip body 111 of the water-distributing half strip 11, so that the multiple water-distributing strips 1 are connected in parallel through the screw rod 9 to form a large plane, which helps to constrain the liquid to pass through the multiple water-distributing holes 2 well.

[0039] Reference Figure 1 and Figure 2 The two ends of the multiple screw rods 9 are respectively sleeved with brackets 10, and the multiple water balancing strips 1 are located between the two brackets 10. The bracket 10 abuts against the water balancing strip 1 close to one side. The bracket 10 is used to be arranged in a thin film evaporation device. The two ends of the screw rods 9 are threadedly connected to a clamping nut (not shown in the figure), and the clamping nut tightens the bracket 10, so that the bracket 10 clamps the multiple water balancing strips 1, thereby realizing the connection between the multiple water balancing strips 1 and improving the clamping effect of the adjacent water balancing strips 1 on the film.

[0040] Reference Figure 4 and Figure 5 The strip body 111 is rotatably provided with an inclined plate 12 on one side away from the distribution box 3, and a rotating shaft 13 is fixedly penetrated on the inclined plate 12. The rotating shaft 13 is rotatably provided on the corresponding strip body 111, and the rotating axis of the rotating shaft 13 is parallel to the length direction of the corresponding strip body 111. The rotating shaft 13 is located at the fin 5 close to the corresponding water balancing strip 1 (refer to Figure 2) on one side of the center, a torsion spring 14 is movably sleeved on the rotating shaft 13, one end of the torsion spring 14 is fixed on the corresponding strip 111, and the other end is fixed on the inclined plate 12. When the torsion spring 14 is in a natural state, the inclined plate 12 is away from the distribution box 3 (refer to Figure 1 ) is inclined toward the direction away from the center of the corresponding water equalizing strip 1, that is, the spacing between the corresponding inclined plates 12 on both sides of each water equalizing strip 1 gradually increases toward the direction away from the distribution box 3. When the two water equalizing half strips 11 are spliced, the rotating shafts 13 on the strip bodies 111 on both sides have a certain gap to facilitate the passage of steam.

[0041] When in use, the liquid flowing from the water-distributing hole 2 is guided to the outer wall of the film along the inclined plate 12, further ensuring that the liquid flows evenly to the outer wall of the film to form a film, and preventing the liquid in the water-distributing hole 2 from falling directly downward. As the amount of liquid increases, the liquid will drive the inclined plate 12 to rotate downward, expanding the gap between the edge of the inclined plate 12 and the outer wall of the film, so as to facilitate the rapid flow of the liquid.

[0042] The implementation principle of Example 1 of the present application is as follows: when in use, the feed liquid enters the distribution box 3 from the liquid inlet pipe at the top of the thin film evaporation device through the pump body, and then the feed liquid flows evenly to the multiple water equalization strips 1 through the multiple water holes 4 on the bottom wall of the distribution box 3, and then the feed liquid flows along the multiple water equalization holes 2 on the water equalization strip 1. Since the upper end of the film is clamped between adjacent water equalization strips 1, the feed liquid passing through the water equalization holes 2 flows along the corresponding inclined plates 12 to the outer wall of the adjacent film, and flows from top to bottom to form a film, thereby helping to achieve uniform flow of the feed liquid along the outer wall of each film, greatly improving the water equalization effect.

[0043] Embodiment 2: Reference Figure 1 and Figure 6 The difference between this embodiment and embodiment 1 is that a support plate 27 is fixed in the distribution box 3, and a paddle 20 is rotatably arranged on the support plate 27. The paddle 20 is located at the outlet of the liquid inlet pipe connected to the distribution box 3, and the rotation axis of the paddle 20 is parallel to the feeding direction of the slurry. Specifically, the rotation axis of the paddle 20 is arranged in the horizontal direction so that when the slurry entering from the liquid inlet pipe is sprayed on the paddle 20, the paddle 20 can be driven to rotate. The blade 20 is coaxially connected to a first connecting rod 21, and a first bevel gear 22 is fixedly sleeved on the end of the first connecting rod 21 away from the blade 20. A rotating rod 23 is arranged at the center position of the distribution box 3 and rotates along the vertical direction. A cleaning brush 24 is fixed on the rotating rod 23. The length direction of the cleaning brush 24 is perpendicular to the rotation axis of the rotating rod 23. The bristles of the cleaning brush 24 abut against the bottom wall of the distribution box 3. A second connecting rod 25 is coaxially fixedly connected to the rotating rod 23. A second bevel gear 26 is fixedly sleeved on the second connecting rod 25, and the second bevel gear 26 meshes with the first bevel gear 22.

[0044] The implementation principle of Example 2 of the present application is as follows: when liquid is fed into the distribution box 3, the liquid is sprayed onto the paddle 20 through the liquid inlet pipe, driving the paddle 20 to rotate and work. The rotation of the paddle 20 drives the first connecting rod 21 and the first bevel gear 22 to rotate, and the first bevel gear 22 drives the second bevel gear 26 to rotate, thereby driving the cleaning brush 24 to rotate through the second connecting rod 25 and the rotating rod 23, so that the cleaning brush 24 works to remove impurities and scale at the water hole 4.

[0045] Embodiment 3: Reference Figure 2 and Figure 7 The difference between this embodiment and embodiment 1 is that water-dividing scrapers 17 are distributed between adjacent fins 5 on the strip body 111, and the water-dividing scrapers 17 are slidably arranged on the corresponding strip body 111. The sliding direction of the water-dividing scraper 17 is parallel to the length direction of the strip body 111, and the water-dividing scraper 17 abuts against a side of the corresponding strip body 111 close to the fin 5. The water-dividing scraper 17 between the corresponding two water-distributing half strips 11 abuts against each other to divide the water-distributing hole 2 into two parts. A transmission member for driving the multiple water-dividing scraper blades 17 on the corresponding strip body 111 to slide is arranged on the inclined plate 12.

[0046] Reference Figure 6 In order to facilitate the movement of the water-dividing scraper 17 when the inclined plate 12 rotates, the transmission member includes a transmission rod 18, and the transmission rod 18 corresponds to the water-dividing scraper 17 one by one. One end of the transmission rod 18 is hinged with a hinge seat 19, and the other end is hinged to the side of the inclined plate 12 away from the rotating shaft 13. The hinge axis of the transmission rod 18 is perpendicular to the length direction of the strip body 111, and the hinge seat 19 is slidably connected to the corresponding water-dividing scraper 17. The sliding direction of the hinge seat 19 is parallel to the hinge axis of the transmission rod 18.

[0047] The implementation principle of Example 3 of the present application is as follows: when the inclined plate 12 is rotated by the force of the slurry, the inclined plate 12 pulls the water-dividing scraper 17 to slide a certain distance on the strip body 111 through the transmission rod 18. At this time, the water-dividing scraper 17 scrapes the inner wall of the strip body 111 to prevent the inner wall of the strip body 111 from scaling and clogging the water-equalizing holes 2. At the same time, the water-dividing scraper 17 separates the water-equalizing holes 2 to form smaller channels, which helps to ensure that the slurry flows evenly to the inclined plate 12 and further improves the water-equalizing effect.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
