Description

Technical Field

[0001] This utility model relates to the field of high-salt wastewater treatment, and in particular to an evaporation device suitable for the evaporation and crystallization of high-salt wastewater. Background Technology

[0002] Evaporation crystallization of high-salinity wastewater is a common wastewater treatment technology. It is based on the difference in boiling points between water and salts. By heating the wastewater, the water evaporates, and the salt concentration gradually increases. When saturation or supersaturation is reached, the salt crystals precipitate out. This technology can reduce the volume of wastewater and enable resource utilization, and is commonly used for treating high-salinity wastewater generated in industries such as chemical, pharmaceutical, and electroplating.

[0003] High-salinity wastewater contains various pollutants and has a complex composition. Pre-filtration removes large particles and other impurities, creating favorable conditions for subsequent treatment and reducing the risk of equipment clogging and scaling. However, existing filters are typically fixed inside the container with screws, requiring the removal and installation of multiple screws for cleaning or replacement, making the process cumbersome. Furthermore, in the evaporation stage, a stirring rod can ensure even heating of the wastewater and improve evaporation efficiency, but existing stirring rods result in uneven mixing, leading to low evaporation efficiency. To address these technical problems, this application proposes an evaporation device suitable for the evaporation and crystallization of high-salinity wastewater. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an evaporation device suitable for the evaporation and crystallization of high-salt wastewater. By rotating the adjustment knob, the rotating rod is driven to rotate, which in turn drives the limiting block to rotate and release the limiting block, allowing the filter box to be disassembled. During installation, the filter box is inserted back into the connecting groove. Loosening the adjustment knob releases the spring force, causing the rotating rod to reverse and reset the limiting block to fix the filter box.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An evaporation device suitable for evaporating and crystallizing high-salt wastewater includes an evaporation tank. A cover is slidably connected to the outer wall of the evaporation tank. A heating tube is provided on the bottom side of the evaporation tank. An evaporation tube is fixedly connected to the top right side of the evaporation tank. A stirring rod is connected to the bottom side of the inner wall of the evaporation tank via a rotating assembly. A feed pipe is fixedly connected to the top left side of the evaporation tank. A connecting groove is opened on the front side of the feed pipe. A filter box is inserted into the inner wall of the connecting groove. The bottom of the filter box is connected to the bottom side of the inner wall of the connecting groove via a limiting assembly to limit the position of the filter box.

[0006] Furthermore, the rotating assembly includes a rotating sleeve rotatably connected to the top side of the inner wall of the evaporator, the inner wall of the rotating sleeve having a rotating groove, a sliding rod fixedly connected to the outer wall of the stirring rod, the outer wall of the stirring rod being slidably connected to the inner wall of the rotating sleeve, and the inner wall of the rotating groove being slidably connected to the outer wall of the sliding rod.

[0007] Furthermore, the outer wall of the slide bar is rotatably connected to a plurality of balls, and the outer wall of the balls abuts against the inner wall of the connecting groove.

[0008] Furthermore, a stepper motor is fixedly connected to the top of the evaporator, and the top end of the rotating sleeve is fixedly connected to the drive end of the stepper motor.

[0009] Furthermore, the limiting assembly includes two rotating rods connected to the inner wall of the connecting groove by a torsion spring. A limiting block is fixedly connected to the outer wall of the rotating rod. The outer wall of the limiting block is inserted into the bottom of the filter box. An adjusting block is fixedly connected to the outer wall of the rotating rod.

[0010] Furthermore, each of the adjusting blocks has a winding rope fixedly connected to its bottom, and a winding rod is rotatably connected to the inner wall of the connecting groove. The two winding ropes are fixedly connected at their closest ends to the outer wall of the winding rod.

[0011] Furthermore, an adjustment knob is rotatably connected to the front side of the feed tube, and the front end of the winding rod is fixedly connected to the rear end of the adjustment knob.

[0012] This utility model has the following beneficial effects: In this invention, rotating the adjustment knob drives the rotating rod to rotate, which in turn drives the limiting block to rotate and release the limiting of the filter box, allowing the filter box to be disassembled. During installation, the filter box is inserted back into the connecting slot, and the adjustment knob is released to release the spring force, causing the rotating rod to reverse and reset the limiting block to fix the filter box. The entire process does not require the removal of screws, greatly simplifying the disassembly and assembly process of the filter box and facilitating timely cleaning or replacement.

[0013] In this invention, a stepper motor drives the rotating sleeve to rotate in both directions. When the rotating sleeve rotates, its inner wall drives the rotating groove, which in turn drives the sliding rod to slide along the inner wall of the rotating groove. This causes the stirring rod to slide up and down while rotating, making the wastewater more evenly stirred and more fully heated, thereby improving the evaporation efficiency.

When the rotating sleeve 5 rotates, its inner wall drives the rotating groove and the slide rod 8 to slide along the inner wall of the rotating groove, so that the stirring rod 6 slides up and down while rotating. Multiple balls 9 are rotatably connected to the outer wall of the slide rod 8. The outer wall of the balls 9 abuts against the inner wall of the connecting groove to reduce the coefficient of friction when the slide rod 8 slides in the rotating groove. A stepper motor 3 is fixedly connected to the top of the evaporator 1, and the rotation direction is controlled by a pulse signal. The top of the rotating sleeve 5 is fixedly connected to the driving end of the stepper motor 3, and the stepper motor 3 drives the rotating sleeve 5 to rotate in both directions. Reference Figure 1 , Figure 4 and Figure 5A feed pipe 2 is fixedly connected to the top left side of the evaporator 1. A connecting groove is opened on the front side of the feed pipe 2, and a filter box 10 is inserted into the inner wall of the connecting groove to filter particles in the wastewater. Two rotating rods 12 are connected to the inner wall of the connecting groove by torsion springs. The release of the torsion springs drives the rotating rods 12 to rotate. A limit block 13 is fixedly connected to the outer wall of the rotating rod 12. The rotation of the rotating rod 12 drives the limit block 13 to rotate. The outer wall of the limit block 13 is inserted into the bottom of the filter box 10 to fix the filter box 10. An adjustment mechanism is fixedly connected to the outer wall of the rotating rod 12. Block 14 is pulled to rotate the rotating rod 12; each bottom of the adjusting block 14 is fixedly connected to a winding rope 15, and a winding rod 16 is rotatably connected to the inner wall of the connecting groove. The two winding ropes 15 are fixedly connected to the outer wall of the winding rod 16 at their closest ends. The winding rod 16 rotates to wind up the winding ropes 15, and the winding ropes 15 are wound up, thereby pulling the adjusting block 14 to rotate; an adjusting knob 11 is rotatably connected to the front side of the feed pipe 2, and the front end of the winding rod 16 is fixedly connected to the rear end of the adjusting knob 11. Rotating the adjusting knob 11 drives the winding rod 16 to rotate.

[0018] Working principle: When starting work, wastewater is injected into the evaporator 1 through the feed pipe 2. The particles in the wastewater are filtered through the filter box 10. When it is necessary to remove the filter box 10, turn the adjustment knob 11 to drive the winding rod 16 to rotate. The winding rod 16 rotates to wind up the winding rope 15. The winding rope 15 is wound up, which pulls the adjustment block 14 to rotate, causing the rotating rod 12 to rotate, which drives the limit block 13 to rotate to release the limit on the filter box 10, and the filter box 10 can be removed.

At the same time, the stepper motor 3 drives the rotating sleeve 5 to rotate in both directions. When the rotating sleeve 5 rotates, its inner wall drives the rotating groove and the sliding rod 8 to slide along the inner wall of the rotating groove. This causes the stirring rod 6 to slide up and down while rotating to stir the wastewater, thereby making it evenly stirred and improving the evaporation efficiency.
