Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically a glass-lined open reaction vessel. Background Technology

[0002] Glass-lined open reaction vessels are mainly used in the chemical, pharmaceutical, and food industries as a type of corrosion-resistant reaction equipment.

[0003] During use, solid or liquid raw materials are added directly from the tank opening. The stirring blades are driven by a motor to rotate, generating radial and axial flow for mixing. The tank body is equipped with a jacket through which steam or heat transfer oil is introduced. Heat is transferred to the material through the glass lining. A discharge valve is located at the bottom, and viscous materials are discharged under pressure.

[0004] Traditional agitators have a gap between the tank edge and the agitator blades. High-viscosity fluids are difficult to move by the shear force of the agitator blades in the gap, resulting in material stagnation at the edge, forming a dead zone for mixing, which leads to uneven mixing. The material is prone to accumulate and solidify in the gap, causing a decrease in reaction efficiency.

[0005] Therefore, this utility model provides an open-type glass-lined reaction vessel. Utility Model Content

The tank 1 is equipped with a stirring blade 17; a groove 18 is formed in the middle of the stirring blade 17; a support rod 16 is slidably connected to the middle of the groove 18; a spring 19 is fixedly connected to the end of the support rod 16; the end of the spring 19 is fixedly connected to one end of the groove 18; a cleaning assembly 2 is installed in the middle of the tank body 1; an installation assembly 3 is provided between the cleaning assembly 2 and the tank body 1; during operation, the tank cover 11 is opened, and the material is fed in from the top of the tank body 1, the reactant material directly contacts the enamel layer, steam is introduced through the jacket, the required reaction temperature is reached, and the motor 12 is turned on. The output of motor 12 drives the stirring shaft 13 to rotate, and the material is mixed by the rotation of the blades 14. At the same time, the rotation of the blades 14 drives the two fixed rods 15. The springs 19 inside the slide groove 18 move the stirring blades 17 toward the support rod 16. The ends of the multiple stirring blades 17 flexibly fit against the inner wall of the tank 1. As the blades 14 drive the fixed rods 15 to rotate, the material at the edge of the tank 1 is stirred by the multiple stirring blades 17. The cleaning component 2 scrapes off the material on the surface of the stirring blades 17, continuously cleaning its surface. Through the above structure, the ends of the stirring blades 17 flexibly fit against the inner wall of the enamel, which can forcibly scrape the material at the edge of the tank 1, continuously disturb the material at the edge, reduce local material deposition or uneven reaction, and effectively reduce damage caused by hard contact between the stirring blades 17 and the enamel layer in the inner wall of the tank 1. In addition, the staggered stirring blades 17 can form multi-directional fluid shear force when rotating, covering a wider radial and regional area, thereby breaking the stagnation state of the edge material and improving the reaction effect.

[0024] like Figure 2 and Figure 4As shown, the cleaning component 2 includes a connecting rod 21; the end of the connecting rod 21 is installed on the inner wall of the tank 1; two positioning rods 22 are fixedly connected to the middle of the connecting rod 21; a scraper 24 is rotatably connected to the middle of the positioning rod 22; two sets of torsion springs 23 are provided in the middle of the scraper 24 and the positioning rod 22; the two sets of torsion springs 23 are respectively arranged on both sides of the scraper 24; during operation, the connecting rod 21 is installed on the inner wall of the tank 1, and when the fixed rod 15 rotates between the two scrapers 24, the two stirring blades 17 apply pressure to the two scrapers 24, and the scrapers 24 rotate in the middle of the positioning rod 22. At this time, the torsion spring 23 on one side stores the force of the scraper 24 rotation, and at the same time the stirring blades 17 apply pressure to the two scrapers 24. 7 slides to the fixed rod 15, the slide groove 18 retracts, and the end of the scraper 24 contacts the surface of the stirring blade 17. As the stirring blade 17 rotates, the end of the scraper 24 scrapes the surface of the stirring blade 17, causing the surface of the stirring blade 17 to separate from the material, thereby continuously cleaning the surface of the stirring blade 17. Through the above structure, the surface of the stirring blade 17 is continuously scraped when it rotates, and the material on the surface of the stirring blade 17 is removed in time, keeping the surface of the stirring blade 17 clean, maintaining a stable mixing effect, reducing the formation of a heat insulation layer on the surface of the stirring blade 17, which would lead to a decrease in the heat transfer effect of the jacket, efficiently transferring heat, and reducing the problem of local overheating or uneven reaction temperature.

[0025] like Figure 4 As shown, the mounting assembly 3 includes a mounting groove 31; the mounting groove 31 is formed on the inner wall of the tank 1; the mounting groove 31 is located at the top of the tank 1; a fixing ring 34 is fixedly connected to one end of the connecting rod 21; the end of the connecting rod 21 is installed in the middle of the corresponding mounting groove 31; a fixing shaft 32 is fixedly connected to the inner wall of the tank 1; the fixing shaft 32 is located on one side of the mounting groove 31; a locking block 33 is rotatably connected to the middle of the fixing shaft 32; the locking block 33 is located in the middle of the connecting rod 21; during operation, when the connecting rod 21 is installed on the inner wall of the tank 1, the end of the connecting rod 21 is inserted into the corresponding mounting groove 31. The mounting groove 31 should be installed inside, and the locking block 33 should be rotated to slide in the middle of the fixed shaft 32. The locking block 33 rotates and bends elastically into the middle of the mounting groove 31. The locking block 33 locks the fixing ring 34, thereby fixing the end of the connecting rod 21. When disassembling, the locking block 33 can be removed from the middle of the connecting rod 21. The above structure allows for quick disassembly and installation of the scraper 24, and the scraper 24 can be quickly removed for cleaning and sterilization, reducing the growth of microorganisms caused by material residue on the surface of the scraper 24 during use, thereby improving the maintenance efficiency of the scraper 24.

[0026] like Figure 3As shown, a rotating groove 4 is provided at the end of the stirring blade 17; a roller 41 is rotatably connected to the middle of the rotating groove 4; a flexible pad 42 is fixed to the outer wall of the roller 41; during operation, when the stirring blade 17 is in contact with the inner wall of the tank 1, the flexible pad 42 is in flexible contact with the inner wall of the tank 1. When the stirring blade 17 rotates to stir the material inside the tank 1, the roller 41 rotates inside the rotating groove 4. Through the elastic deformation of the roller 41 and the flexible pad 42 in the above structure, they are in contact with the inner wall of the tank 1, so that the stirring blade 17 and the inner wall of the tank 1 form a soft contact, reducing the hard scraping between the stirring blade 17 and the inner wall of the tank 1, reducing the frictional resistance between the stirring blade 17 and the inner wall of the tank 1, and extending the service life of the enamel layer of the inner wall of the tank 1.

[0027] like Figure 1 and Figure 4 As shown, a collection box 5 is installed on the outer wall of the tank 1; a fixing component 6 is provided between the collection box 5 and the tank 1; during operation, the collection box 5 is installed on the outside of the tank 1 through the fixing component 6. When foam is generated during the reaction process and overflows from the top of the tank 1, the overflowing liquid enters the collection box 5 for collection. The above structure effectively collects the overflow liquid, reduces corrosion of the outer wall of the tank 1 or other equipment, and effectively reduces the accumulation of liquid on the ground, improving the cleanliness of the surrounding environment.

[0028] like Figure 4 As shown, the fixing component 6 includes a groove 61; the groove 61 is formed on the side wall of the collection box 5; a slot 62 is formed on the top of the groove 61; a fixing block 63 is fixedly connected to the outer side wall of the tank body 1; the collection box 5 and the fixing block 63 are arranged in a ring; during operation, when the collection box 5 is installed on the outer side wall of the tank body 1, the collection box 5 is moved downward from the top of the tank body 1. The fixing block 63 is flexibly set. When one side of the collection box 5 contacts the fixing block 63, the fixing block 63 elastically contracts. When the groove 61 moves to the position of the fixing block 63, the fixing block 63 elastically resets and enters the groove 61. Then the collection box 5 is moved downward so that the fixing block 63 enters the slot 62, thereby installing and fixing the collection box 5. Through the above structure, the collection box 5 can be quickly installed and disassembled, so that the collection box 5 can quickly carry out subsequent processing after collecting the liquid, reducing the problem of difficult cleaning of the collected liquid.

[0029] like Figure 4 As shown, the top side of the collection box 5 is set with a slope. When the liquid overflows during operation, it flows down the outer wall of the tank 1 and is guided into the collection box 5 by the slope. The above structure enables the slope on one side of the collection box 5 to form a continuous transition surface with the outer wall of the tank 1, so that the overflow liquid is accurately guided into the collection box 5 for collection.

[0030] During operation, the tank lid 11 is opened, and the material is fed into the tank 1 from the top. The reactants directly contact the enamel layer. Steam is introduced through the jacket to reach the required reaction temperature. The motor 12 is turned on, causing the output of the motor 12 to drive the stirring shaft 13 to rotate. The rotating blades 14 mix the materials. At the same time, the rotation of the blades 14 drives the two fixed rods 15. The springs 19 inside the slide groove 18 move the stirring blades 17 towards one end of the support rod 16. The ends of the multiple stirring blades 17 flexibly fit against the inner wall of the tank 1. As the blades 14 drive the fixed rods 15 to rotate, the multiple stirring blades 17 agitate the material at the edge of the tank 1. The cleaning assembly 2 then cleans the material. Material is scraped off the surface of the stirring blade 17, continuously cleaning its surface. The connecting rod 21 is installed on the inner wall of the tank 1. When the fixed rod 15 rotates between the two scrapers 24, the two stirring blades 17 apply pressure to the two scrapers 24. The scrapers 24 rotate in the middle of the positioning rod 22. At this time, the torsion spring 23 on one side stores the force of the scraper 24's rotation. At the same time, the stirring blade 17 slides towards the fixed rod 15, the slide groove 18 retracts, and the end of the scraper 24 contacts the surface of the stirring blade 17. As the stirring blade 17 rotates, the end of the scraper 24 scrapes the surface of the stirring blade 17, causing the surface of the stirring blade 17 to separate from the material, thereby continuously cleaning the surface of the stirring blade 17. The connecting rod 21 is then installed on the inner wall of the tank 1. When installed on the inner wall of tank 1, insert the end of connecting rod 21 into the corresponding mounting groove 31, rotate the locking block 33 to make it slide in the middle of the fixed shaft 32, the locking block 33 rotates and elastically bends into the middle of the mounting groove 31, and the locking block 33 locks the fixing ring 34, thereby fixing the end of connecting rod 21. When disassembling, simply remove the locking block 33 from the middle of connecting rod 21. When the stirring blade 17 is in contact with the inner wall of tank 1, the flexible pad 42 is in flexible contact with the inner wall of tank 1. When the stirring blade 17 rotates to stir the material inside tank 1, the roller 41 rotates inside the rotating groove 4. The collection box 5 is installed on the outside of tank 1 through the fixing component 6. When the material is in the reverse... When foam overflows from the top of the tank 1 during the process, the overflowing liquid enters the collection box 5 for collection. When the collection box 5 is installed on the outer wall of the tank 1, the collection box 5 is moved downward from the top of the tank 1. The fixing block 63 is flexibly designed. When one side of the collection box 5 contacts the fixing block 63, the fixing block 63 elastically contracts. When the groove 61 moves to the position of the fixing block 63, the fixing block 63 elastically resets and enters the groove 61. Then the collection box 5 is moved downward so that the fixing block 63 enters the slot 62, thereby installing and fixing the collection box 5. When the liquid overflows, it flows downward along the outer wall of the tank 1 and is guided into the collection box 5 by the inclined surface.
