Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-8 As shown, this utility model provides a technical solution: a wastewater evaporator for wheat starch, comprising a tank 1, a top cover 2 and a bottom cover 3, wherein the top cover 2 is connected to a liquid inlet pipe 11 and the bottom cover 3 is connected to a finished liquid outlet pipe 15, the tank 1 is connected to a hot steam inlet pipe 12, an exhaust pipe 13 and a condensate outlet pipe 14, and an evaporation assembly 6 is provided inside the tank 1, the evaporation assembly 6 including multiple sets of heating tubes 61, and each set of heating tubes 61 is provided with a cleaning assembly 7 for cleaning the inner walls of the multiple sets of heating tubes 61. The cleaning component 7 includes a long rod 71 that is slidably installed inside multiple sets of heating tubes 61, and multiple sets of cleaning buckets 72 are fixedly installed on the long rod 71. Both the long rod 71 and the cleaning buckets 72 are made of stainless steel. The cleaning buckets are attached to the inner wall of the multiple sets of heating tubes. Multiple sets of filter holes are opened on the multiple sets of cleaning buckets 72 for wastewater flow filtration. The cleaning component 7 is provided with a control component 8 for controlling the forward and backward movement of the cleaning component 7. The evaporation component 6 is provided with a limit component 9 for limiting and fixing the control component 8.

[0019] As one implementation method in this embodiment, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the evaporation assembly 6 also includes a first connecting plate 62 and a second connecting plate 63 fixedly installed inside the tank 1. Multiple sets of heating tubes 61 are connected between the first connecting plate 62 and the second connecting plate 63. A filter ring 5 is engaged on the first connecting plate 62. The first connecting plate 62 and the second connecting plate 63 neatly and stably install the multiple sets of heating tubes 61 inside the tank 1, forming a complete evaporation area. Multiple sets of filter grooves are opened on the filter ring 5, and two sets of pull grooves 51 are also opened at the top of the filter ring 5. The filter ring 5 can effectively intercept large particulate impurities and suspended solids in the waste liquid, preventing these impurities from entering the heating tubes 61 and causing blockage, affecting the heating effect and evaporation efficiency. At the same time, the engaging installation method facilitates the disassembly and replacement of the filter ring 5, and the pull grooves 51 provide a leverage point for the operator to facilitate the installation of the filter ring 5.

[0020] As one implementation method in this embodiment, such as Figure 4 and Figure 5 As shown, the control component 8 includes a circular plate 81 fixedly installed at the end of the long rod 71. A pull ring 82 is fixedly installed on the circular plate 81, and multiple sets of annular grooves 83 are formed on the circular plate 81. The multiple sets of annular grooves 83 facilitate the flow of liquid. The circular plate 81 serves as the control component of the long rod 71, and provides an application point for the operator through the pull ring 82, making it convenient for the operator to control the movement of the long rod 71.

[0021] As one implementation method in this embodiment, such as Figure 5 and Figure 6 As shown, the limiting component 9 includes multiple sets of screws 92 fixedly installed on the second connecting plate 63, and the multiple sets of screws 92 penetrate the circular plate 81. Each set of screws 92 is fixedly installed with a limiting plate 93, and each set of screws 92 is rotatably installed with a bolt 91. Through the cooperation of the screws 92, the limiting plate 93 and the bolt 91, the circular plate 81 is limited and fixed, and at the same time, the circular plate 81 can be unlocked.

[0022] As one implementation method in this embodiment, such as Figure 6 As shown, the multiple sets of cleaning hoppers 72 are conical in shape. The conical shape of the cleaning hoppers 72 can reduce the resistance to the flow of wastewater and ensure that the wastewater can pass smoothly through the heating pipe 61.

[0023] As one implementation method in this embodiment, such as Figure 1 As shown, two sets of mounting rings 4 are fixedly installed on the tank body 1. The two sets of mounting rings 4 are used for the fixed installation of the tank body 1, which facilitates the disassembly and transportation of the tank body 1.

[0024] As one implementation method in this embodiment, such as Figure 1As shown, an electronic valve 16 is installed on the exhaust pipe 13, which can precisely control the exhaust flow and pressure of the exhaust pipe 13.

[0025] Working principle: Tank 1, top cover 2, and bottom cover 3 are connected by flanges. First, wheat starch waste liquid enters tank 1 through the liquid inlet pipe 11. In the initial stage of the waste liquid entering tank 1, it will first pass through the filter ring 5. The multiple sets of filter grooves on the filter ring 5 can effectively intercept large particulate impurities and suspended solids that may be present in the waste liquid, preventing these impurities from entering the subsequent heating pipe 61, avoiding blockage or damage to the heating pipe 61, and ensuring the smoothness of the evaporation process and heating efficiency. The waste liquid, after preliminary filtration, flows evenly into multiple sets of heating tubes 61. Simultaneously, hot steam enters the tank 1 through the hot steam inlet pipe 12, distributing within the tank 1 and exchanging heat thoroughly with the heating tubes 61. Due to the high temperature of the hot steam, it transfers heat to the heating tubes 61, causing their temperature to rise. As the waste liquid flows within the heating tubes 61, it comes into contact with the inner wall of the tubes, absorbing heat and gradually increasing in temperature. With this increase in temperature, the water in the waste liquid begins to evaporate, forming water vapor. The condensate generated on the outer surface of the heating tube 61 flows down the tube wall and is eventually discharged from the condensate outlet pipe 14 into the tank 1. The finished liquid after evaporation and concentration continues to flow towards the bottom cover 3 and is finally discharged from the finished liquid outlet pipe 15 into the tank 1, entering the subsequent processing stage or collection device. The water vapor generated during the evaporation process will accumulate in the upper space of the tank 1 and be discharged from the tank 1 through the exhaust pipe 13. The electronic valve 16 installed on the exhaust pipe 13 can adjust the flow rate and pressure of the exhaust according to actual needs. When it is necessary to perform regular cleaning and inspection of the tank 1, firstly, by removing the top cover 2 and bottom cover 3 on the tank 1, the tank 1 is opened, and the multiple sets of screws 92 fixedly installed on the second connecting plate 63 are located. These screws 92 pass through the circular plate 81. By rotating the bolts 91 on the screws 92, the bolts 91 no longer exert pressure on the circular plate 81, thereby unlocking the circular plate 81. By pulling the ring 82 fixedly installed on the circular plate 81 at the end of the long rod 71, the circular plate 81 is moved. The movement of the circular plate 81 will cause multiple sets of long rods 71 ​​to slide out of the heating tube 61. During the sliding process of the long rod 71, multiple sets of cleaning buckets 72 fixedly installed on the long rod 71 will contact the inner wall of the heating tube 61 and scrape off the dirt on the inner wall. The multiple sets of filter holes opened on the cleaning buckets 72 will not affect the normal flow of wastewater during normal use, ensuring the continuity of the evaporation process. As the long rod 71 is continuously pulled out, the cleaning bucket 72 will clean and remove the dirt from the inner wall of the heating tube 61. The operator can collect and dispose of the removed dirt to keep the inner wall of the heating tube 61 clean.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
