Description

Technical Field

[0001] The utility model belongs to the technical field of propylene oxide preparation, and particularly relates to a water-saving device for propylene oxide preparation. Background Art

[0002] Propylene oxide is an important basic chemical raw material, mainly used in the production of polyether polyols, propylene glycol and various non-ionic surfactants. Propylene oxide has a wide range of uses and is widely used in the petroleum, chemical, pesticide, textile, daily chemical and other industries. In the process of preparing propylene oxide, an evaporator is usually required. The evaporator is a device used to heat and vaporize liquid substances. It can heat and convert liquid propylene oxide into gas for subsequent process treatment. Among them, the thin film evaporator is a frequently used evaporator. The operating procedures of the thin film evaporator include feeding, heating, evaporation, discharging and other steps. In the feeding stage, the material needs to be added to the feed port and enter the dispersion plate. In the heating stage, the heating steam enters the heating tube to heat the material. In the evaporation stage, the material is rapidly vaporized in the heating tube, and the steam is discharged from the evaporation port. Finally, in the discharging stage, the residual material needs to be discharged. When the steam is discharged from the pipeline, it may carry too many impurities or other debris, making the steam unable to be recycled and reused, resulting in a waste of water resources. Therefore, a Y-type filter tube is often used to filter the steam to reduce excessive losses.

[0003] The problem with the prior art is that the Y-type filter tube and the evaporator are usually fixedly connected by bolts, and the bolts may rust after long-term use, making it difficult to disassemble and cleaning the Y-type filter tube. Utility Model Content

It solves the problem that the existing Y-type filter tube and the evaporator are usually fixedly connected with bolts, and the bolts may rust after long-term use, making it difficult to disassemble and increasing the difficulty of cleaning the Y-type filter tube.

By setting up the fixing structure, the fixing bolt can drive the rotation of the rotating arm through the rotating disk to fix and limit the connection.

[0008] As a preferred embodiment of the utility model, the outer surface of the rotating disk is fixedly connected to a rotating block, the surface on the left side of the rotating block is rotatably connected to a linkage block, the inner wall of the linkage block is threadedly connected to a fixing bolt, and by setting the rotating disk, the fixing bolt drives the linkage block to move when it rotates, thereby causing the rotating block to drive the rotating disk to rotate.

[0021] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

The Y-shaped filter tube 2 is arranged on the right side of the main body 1, and the left interface of the Y-shaped filter tube 2 is fitted with the pipe interface of the main body 1. The base 3 is arranged at the connection between the main body 1 and the Y-shaped filter tube 2. The fixed structure 4 is fixedly connected to the inner wall of the base 3, and the pipe interface of the main body 1 is fixedly connected to the Y-shaped filter tube 2 through the fixed structure 4.

[0023] refer to Figure 2 and Figure 3 An adjustment opening 301 is provided on the outer surface of the base 3 , and circular openings 302 are provided on the surfaces on the left and right sides of the base 3 , respectively. A fixing seat 303 is fixedly connected to the inner wall on the right side of the base 3 .

[0024] The above solution is adopted: by setting the base 3, the connection between the pipeline interface of the body 1 and the Y-type filter tube 2 is located in the circular opening 302, and the connection is fixed and limited by operating the fixing structure 4 through the adjustment opening 301.

[0025] refer to Figure 2 The fixing structure 4 includes a rotating disk 5, a rotating arm 6 and a fixing bolt 7. The rotating disk 5 is sleeved on the surface of the circular opening 302. The rotating arm 6 is arranged on the outer surface of the rotating disk 5. The fixing bolt 7 is rotatably connected to the inner wall of the fixing seat 303.

[0026] The above solution is adopted: by providing the fixing structure 4, the fixing bolt 7 can drive the rotating arm 6 to rotate through the rotating disk 5, so as to fix and limit the connection.

[0027] refer to Figure 3 and Figure 4 The outer surface of the rotating disk 5 is fixedly connected with a rotating block 501 , and the surface on the left side of the rotating block 501 is rotatably connected with a linkage block 502 , and the inner wall of the linkage block 502 is threadedly connected with the fixing bolt 7 .

[0028] The above solution is adopted: by setting the rotating disk 5, when the fixing bolt 7 rotates, the linkage block 502 is driven to move, so that the rotating block 501 drives the rotating disk 5 to rotate.

[0029] refer to Figure 3 and Figure 4 There are three rotating arms 6, and the right sides of the three rotating arms 6 away from one end are fixedly connected with a rotating shaft 601. The three rotating shafts 601 are equidistantly connected to the right side of the inner wall of the base 3, and the surfaces of the three rotating arms 6 are respectively sleeved with linkage sleeves 602.

[0030] The above solution is adopted: by providing the rotating arm 6, the rotating arm 6 is driven by the linkage sleeve 602 to rotate, thereby driving the fixed plate 603 to move.

[0031] refer to Figure 4 The right sides of the three linkage sleeves 602 are rotatably connected to the surface of the left side of the rotating disk 5 through the rotating shaft.

[0032] The above solution is adopted: by setting the linkage sleeve 602, the rotating disk 5 drives the linkage sleeve 602 to move when rotating, and drives the ends of the rotating arms 6 that are close to each other to move closer.

[0033] refer to Figure 4 The ends of the three rotating arms 6 that are close to each other are rotatably connected to the fixed plates 603 through the rotating shafts, and the inner walls of the three fixed plates 603 are respectively fitted with the connection between the pipeline interface of the body 1 and the Y-type filter tube 2.

[0034] The above solution is adopted: by providing the fixing plate 603, the rotating arm 6 drives the fixing plate 603 to fix and limit the connection when rotating.

[0035] The working principle of this utility model:

[0036] When in use, the pipe interface of the main body 1 is connected to the Y-type filter tube 2, and the base 3 is placed at the connection, and then the fixing bolt 7 is rotated. When the fixing bolt 7 is rotated, it drives the linkage block 502 to move closer to the fixed seat 303. When the linkage block 502 moves, it drives the rotating block 501, and the rotating block 501 drives the rotation of the rotating disk 5. When the rotating disk 5 rotates, it drives the three linkage sleeves 602 to move respectively. At the same time, the three linkage sleeves 602 drive the ends of the three rotating arms 6 that are close to each other to move and approach respectively. As the three rotating arms 6 rotate, the three fixed blocks are driven respectively and fixed at the connection.

[0037] In summary: the water-saving device for preparing propylene oxide, through the coordinated use of the main body 1, the Y-type filter tube 2, the base 3 and the fixing structure 4, solves the problem that the Y-type filter tube and the evaporator are usually fixedly connected with bolts, and the bolts may rust after long-term use, making it difficult to disassemble and increasing the difficulty of cleaning the Y-type filter tube.
