Description

Technical Field

[0001] This utility model relates to the technical field of evaporation and stirring equipment, specifically to an evaporation and stirring device. Background Technology

[0002] Currently, evaporation is the primary method for waste liquid treatment and recycling. This method and process are widely used in modern industrial production, with the main purpose of removing water from waste liquid to produce distilled water and increasing the concentration of the waste liquid to meet subsequent treatment requirements. Traditional evaporation stirring equipment uses stirring structures such as brushes, but these brush stirring structures are prone to bending, splitting, or falling off after long-term use, especially when in contact with hard objects or subjected to high-frequency friction. They need to be replaced regularly, and they cannot effectively deal with salt agglomeration and "snowballing" phenomena, resulting in incomplete stirring, easy material accumulation, which affects evaporation heat exchange, leads to high moisture content in the residue, reduces evaporation efficiency, increases evaporation time, increases evaporation energy consumption, and increases operating costs.

[0003] Therefore, it is necessary to design an evaporation stirring device to solve the above problems. Utility Model Content

A spring is sleeved on the screw between the scraper seat and the first support plate so that the scraper elastically abuts against the inner wall of the tank. The extension and contraction of the spring is 2mm.

[0009] Furthermore, the scraper seat is U-shaped, the scraper is fitted into the U-shaped groove of the scraper seat, the scraper is inclined along the spiral direction of the propeller blade, the head and tail ends of adjacent scrapers are arranged opposite each other, the scraping end of the scraper is higher than the radial extension end of the stirring rod, and the height difference is 10mm to 15mm.

[0010] Furthermore, there are at least two toothed plates, each toothed plate has a connecting port, and the connecting rod passes through the connecting port and is fixed to the stirring rod. The toothed plates have protruding teeth at both ends.

The rake teeth are obliquely arranged towards the discharge end cover, and the distance between the rake teeth and the discharge end cover is 2mm to 3mm.

[0024] like Figures 1 to 8 As shown, an evaporation stirring device of this utility model includes a tank 2 mounted on a frame 1. The tank 2 is provided with a stirring assembly for stirring materials. The stirring assembly includes a stirring shaft 3 arranged along the axial direction of the tank 2. Several first and second stirrers are arranged in a staggered manner on the stirring shaft 3. The first and second stirrers are coaxial and independently arranged. The first stirrer includes a scraper 4 for scraping the inner wall of the tank 2. The second stirrer includes a toothed plate 5 for crushing the materials in the tank 2.

[0025] Several radially extending stirring rods 6 are arranged in a 120° circumference on the stirring shaft 3. The stirring rods 6 are arranged alternately and at intervals. The propeller blades 7 are continuously arranged around the circumference of the stirring shaft 3 through the stirring rods 6. The first stirrer, the second stirrer, and the propeller blades 7 are arranged alternately and at intervals. Adjacent stirring rods 6 on the same side are connected by a support plate. There are two support plates, namely a first support plate 8 and a second support plate 9. The first support plate 8 and the second support plate 9 are arranged vertically. A support connector 11 is connected between the first support plate 8 and the second support plate 9.

[0026] The first agitator also includes several scraper seats 12, each equipped with a scraper 4. Two screws 13 are connected to the bottom of the scraper seat 12. The screws 13 pass through the first support plate 8 and the second support plate 9 and are connected to the fixing ring 10. A spring 14 is fitted on the screw 13 between the scraper seat 12 and the first support plate 8 so that the scraper 4 elastically abuts against the inner wall of the tank 2. The extension and contraction of the spring 2 is 2mm. The scraper seat 12 is U-shaped, and the scraper 4 is fitted into the U-shaped groove of the scraper seat 12. The scraper 4 is inclined at 45° along the spiral direction of the propeller blade 7. The head and tail ends of adjacent scrapers 4 are arranged opposite each other. The scraping end of the scraper 4 is higher than the radial extension end of the agitator rod 6, and the height difference is 10mm.

[0027] There are at least two toothed plates 5. The toothed plates 5 have a connection port 15. The connecting rod 16 passes through the connection port 15 and is fixed to the stirring rod 6. The toothed plates 5 have protruding teeth 17 at both ends. The toothed plates 5 are T-shaped. The bottom of the toothed plates 5 is fixed to the first support plate 8. The top of the toothed plates 5 is flush with the radial extension end of the stirring rod 6. The head and tail ends of adjacent toothed plates 5 are arranged opposite each other. The toothed plates 5 are inclined at 45° along the spiral direction of the propeller blade 7.

[0028] The feed end of the tank 2 is equipped with a feed end cover 18, and the discharge end of the tank 2 is equipped with a discharge end cover 19. The stirring shaft 3 is rotatably connected between the feed end cover 18 and the discharge end cover 19. The discharge end cover 19 is provided with a discharge port 20. The stirring shaft 3 is connected to the drive mechanism. For the drive mechanism that can drive the stirring shaft to rotate, different drive structures or drive methods can be adopted, as long as the stirring shaft can be driven to rotate. In this embodiment, the drive mechanism includes a drive motor 21, a reducer 22, a drive gear 23, and a driven gear 24 connected to each other. The drive motor 21 and the reducer 22 are both mounted on the frame 1. The output end of the reducer 22 is connected to the drive gear 23. The driven gear 24 is mounted on the drive shaft 25. The drive shaft 25 is connected to the end of the stirring shaft 3 located at the feed end cover 18 through the bushing 26. The drive gear 23 and the driven gear 24 are connected by a chain 27.

[0029] Several rake teeth 28 are provided on the stirring rod 6 at the end of the stirring shaft 3 along the radial extension direction. The rake teeth 28 are obliquely set towards the discharge end cover 19. The distance between the rake teeth 28 and the discharge end cover 19 is 2mm. The rake teeth 28 not only facilitate the stirring and dispersion of materials, but also facilitate further discharge.

[0030] In this invention, the first and second agitators are coaxial and independently arranged, and the scraper 4 in the first agitator is also an independent structure. Therefore, even if one scraper 4 encounters crystalline salt, it will not affect the normal operation of the other scrapers 4. Each scraper 4 shares the load stress experienced during the mixing process, extending the service life of the agitator rod 6, support plate, etc. Furthermore, a spring 14 is fitted on the screw 13, allowing the scraper 4 to elastically contact the inner wall of the tank 2. This allows it to adapt to the shape of the inner wall of the tank 2 and the flow state of the material during mixing, effectively scraping off the material adhering to the inner wall of the tank 2, preventing material crusting and solidification, and ensuring the system's heat exchange efficiency and equipment stability. In addition, the inclined design of the scraper 4 and the relative arrangement of the head and tail ends of the adjacent toothed plates 5 not only... The design ensures that every section of the inner wall of tank 2 can be scraped and has a certain material transfer function, thus improving work efficiency. At the same time, the second agitator structure can effectively break up material agglomerates, disperse particles, or shear viscous media, preventing agglomeration and "snowballing" phenomena caused by crystallization and salt precipitation during the evaporation process. The inclined design of the toothed plate 5 and the relative arrangement of the head and tail ends of adjacent toothed plates 5 also ensure that every section of material in tank 2 can be stirred and dispersed, and has a certain material transfer function, further improving work efficiency. The stirred and dispersed material is discharged through the discharge port 20 on the discharge end cover 19, thereby improving evaporation heat exchange efficiency, reducing residue moisture content, saving discharge time, making discharge more thorough, and reducing operating costs.
