Description

Technical Field

[0001] The utility model relates to the field of evaporation devices, and particularly relates to a falling film evaporation device for ultrafine fiber process water. Background Technique

[0002] When treating ultrafine fiber process wastewater, an evaporator, a reboiler and an MVR heat pump are usually used in combination to treat the wastewater. The MVR heat pump is a mechanical vapor recompression technology, which is a commonly used device in the concentrated evaporation process. It utilizes the secondary steam and energy generated by the evaporation system itself to lift the low-grade steam to a high-grade steam heat source through the mechanical work of a compressor, and then returns it to the evaporation system to provide heat. In this way, heat is cyclically provided to the evaporation system, thereby reducing the demand for external energy.

[0003] When the evaporator, the reboiler and the MVR heat pump are working, due to the difference in their installation positions and the positions of the inlet and outlet ports, the connecting pipes between them have a certain length and height. Therefore, in order to ensure the stability of the connecting pipes, they are usually installed and supported by support frames, fixing parts and bolts. However, when using the support frames, fixing parts and bolts for fixing and supporting, tools are still needed to disassemble them when disassembling and maintaining the pipes, which reduces the installation and disassembly rate of the pipes.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides a falling film evaporation device for ultrafine fiber process water as Figures 1-3 shown, which includes a substrate 1, an evaporator 2, a reboiler 3, and a circulation pump 4. The evaporator 2, the reboiler 3, and the circulation pump 4 are installed on the top of the substrate 1. The evaporator 2 is connected to the reboiler 3. A first connecting pipe 5 is connected between the reboiler 3 and the circulation pump 4, and a second connecting pipe 6 is connected between the circulation pump 4 and the evaporator 2. A support assembly 7 is provided on the top of the substrate 1. The support assembly 7 includes a support frame 71, a first fixing collar 72, a second fixing collar 73, and a clamping assembly 74. The support frame 71 is fixedly connected to the top of the substrate 1. The first fixing collar 72 and the second fixing collar 73 are respectively fixedly sleeved on the outer walls of the second connecting pipe 6 and the first connecting pipe 5. The clamping assembly 74 is installed on the top of the support frame 71. The support frame 71 is connected to the first fixing collar 72 and the second fixing collar 73 through the clamping assembly 74. The support frame 71 can maintain a stable connection state with the first fixing collar 72 and the second fixing collar 73 through the clamping assembly 74, so that the support frame 71 supports and fixes the second connecting pipe 6 and the first connecting pipe 5 respectively through the first fixing collar 72 and the second fixing collar 73. By releasing the clamping state of the clamping assembly 74 with the first fixing collar 72 and the second fixing collar 73, the second connecting pipe 6 and the first connecting pipe 5 can be directly disassembled and maintained.

[0027] Further, the clamping component 74 includes a support plate 741, a fixing plate 742 and a first positioning plate 743. The support plate 741 is fixedly connected to the top of the support frame 71. One side of the first fixing collar 72 and the second fixing collar 73 are respectively fixedly connected to the fixing plate 742, and the fixing plate 742 is located on the top of the support plate 741. An installation hole 745 is formed in the top of the fixing plate 742. The outer wall of the first positioning plate 743 is slidably sleeved in the inner cavity of the installation hole 745. The first positioning plate 743 can improve the connection stability between the support plate 741 and the fixing plate 742.

[0028] In particular, positioning holes 746 are formed in one side of the fixing plate 742 and one side of the first positioning plate 743. A positioning rod 744 is slidably sleeved in the inner cavity of the positioning hole 746. The positioning rod 744 can lock the fixing plate 742 and the first positioning plate 743, thereby further improving the connection stability between the support plate 741 and the fixing plate 742. A connection disc 747 is fixedly connected to the end of the positioning rod 744. A top plate 748 is arranged on the top of the support plate 741. Second positioning plates 7410 are symmetrically and fixedly connected to the bottom of the top plate 748. The outer walls of the second positioning plates 7410 are slidably sleeved in the inner cavity of the installation hole 745. A binding plate 749 is fixedly connected to the bottom of the top plate 748. The connection disc 747 is clamped between the binding plate 749 and the fixing plate 742. A guiding column 7411 is fixedly connected to the top of the support plate 741. Under the action of the guiding column 7411, the top plate 748 can be rotatably arranged on the top of the support plate 741. When the second positioning plate 7410 is clamped with the fixing plate 742, the top plate 748 cannot rotate, and the binding plate 749 can limit the connection disc 747, thereby ensuring the clamping stability of the positioning rod 744 with the fixing plate 742 and the first positioning plate 743. Move the top plate 748 upward to separate the second positioning plate 7410 from the fixing plate 742, and the top plate 748 can drive the binding plate 749 to rotate, so that the binding plate 749 is separated from the connection disc 747, and thus the positioning rod 744 can be pulled out.

[0029] Further, a fixing frame 7412 is fixedly connected to the bottom of the top plate 748. Through holes matching the guide posts 7411 are provided in the top of the top plate 748 and the top of the fixing frame 7412. A limiting spring 7413 acting on the fixing frame 7412 is arranged on the outer wall of the guide post 7411. An annular groove is provided on the outer wall of the guide post 7411. The guide post 7411 is rotationally inserted and sleeved with a limiting plate 7415 through the annular groove. Thus, the limiting plate 7415 can only rotate relative to the guide post 7411 and cannot slide up and down relative to the guide post 7411. A fixing rod 7414 is fixedly connected between the fixing frame 7412 and the top plate 748. The outer wall of the fixing rod 7414 is slidably inserted and sleeved with the limiting plate 7415. The outer wall of the fixing rod 7414 is slidably sleeved with the limiting spring 7413. Under the action of the fixing rod 7414, the limiting spring 7413 and the limiting plate 7415 can rotate synchronously with the top plate 748 and the fixing frame 7412. The limiting spring 7413 is located at the bottom of the limiting plate 7415. Under the action of the limiting plate 7415, the limiting spring 7413 can give a downward elastic force to the top plate 748 through the fixing frame 7412, so that the top plate 748 drives the second positioning plate 7410 to maintain a stable clamping state with the fixing plate 742.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
