Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically a chemical safety feeding device. Background Technology

[0002] Chemical production refers to the process of chemically processing raw materials to obtain valuable products. In chemical production, materials need to be put into a reaction vessel to carry out chemical reactions.

[0003] Based on the above, the inventors have discovered that in the current feeding method, when feeding solid materials, the fixed material is directly fed into the reactor through the feeding port. When the material falls into the solution inside the reactor, it causes liquid to splash, which poses a certain danger. Therefore, a chemical safety feeding device is proposed to optimize the above situation. Utility Model Content

[0004] The purpose of this invention is to provide a chemical safety feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A chemical safety feeding device includes a reactor. A hollow shaft is rotatably connected to the top of the reactor. A matching closed tube is slidably connected inside the hollow shaft. A feeding tube matching the closed tube is slidably connected to the inner side of the closed tube. A sealing plate is fixedly connected to the bottom end of the feeding tube. A feeding hole is opened on the circumference of the bottom side wall of the feeding tube. A matching pressing plate is slidably connected inside the feeding tube. A blind plate is fixedly connected to the top end of the pressing plate through a connecting rod. A flange plate is fixedly connected to the top end of the feeding tube. The blind plate is fixedly installed to the flange plate by a first fixing bolt. A circular hole for the first fixing bolt to pass through is opened on the blind plate. A threaded hole for the first fixing bolt to be threadedly connected is opened on the flange plate. A stop ring is fixedly connected to the closed tube.

[0007] As a further embodiment of this utility model: the top circumferential thread of the hollow shaft is connected to a second fixing bolt, the second fixing bolt is inserted into the hollow shaft and abuts against the outer wall of the closed tube, and the side wall of the hollow shaft is provided with a threaded hole for threaded connection of the second fixing bolt.

[0008] As a further embodiment of this utility model: the top end of the closed tube is circumferentially threaded with a third fixing bolt, the third fixing bolt is inserted into the closed tube and abuts against the outer wall of the feeding tube, and the side wall of the closed tube is provided with a threaded hole for threaded connection of the third fixing bolt.

[0009] As a further improvement of this utility model, a stirring blade is fixedly connected to the outer side of one end of the hollow shaft inserted into the reactor.

[0010] As a further embodiment of this utility model: a first synchronous wheel is fixedly connected to one end of the hollow shaft extending out of the reactor, a second synchronous wheel is provided on the outside of the first synchronous wheel, the second synchronous wheel is fixedly installed at the output end of the drive motor, the drive motor is externally connected to a power supply and a switch, the drive motor is fixedly installed on the side wall of the reactor, and the second synchronous wheel is connected to the first synchronous wheel through a synchronous belt.

[0011] As a further improvement of this utility model: the top side of the reactor is provided with a filling port, and a sealing cap is installed on the top of the filling port.

[0012] As a further embodiment of this utility model: the hollow shaft, the closed tube, and the feeding tube are all provided with guide grooves on their inner sides, and the closed tube, the feeding tube, and the pressing plate are all fixedly connected with guide bars on their outer sides. The guide bars are inserted into the guide grooves and slidably connected. The cooperation between the guide bars and the guide grooves forms a sliding guide and a rotation limit.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The feeding tube of this utility model is set inside a closed tube and sealed by a pressure plate. The closed tube is slidably connected to a hollow shaft, so it can be directly inserted into the reaction solution inside the reactor. By lifting the closed tube, the feeding hole is opened, so as to feed the material under the liquid surface. This effectively avoids the problem of fixed material falling directly onto the liquid inside the reactor and causing liquid splashing during feeding.

[0015] 2. This utility model uses a second fixing bolt to fix the closed tube to the hollow shaft, a third fixing bolt to fix the feeding tube to the closed tube, and a first fixing bolt in conjunction with a flange plate, a blind plate, and a connecting rod to fix the pressure plate. This fixes the position of the closed tube relative to the hollow shaft and the position of the feeding tube relative to the closed tube, thus facilitating feeding operations.

[0016] 3. This utility model forms a sliding guide and rotation limit by the cooperation of guide bars and guide grooves, so that while the hollow shaft drives the stirring blades to rotate and stir, the feeding pipe rotates to form centrifugal feeding. Attached Figure Description

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.

[0024] Please see Figures 1-5 In this embodiment of the present invention, a chemical safety feeding device includes a reactor 1. A hollow shaft 2 is rotatably connected to the top of the reactor 1. A matching closed tube 3 is slidably connected inside the hollow shaft 2. A matching feeding tube 4 is slidably connected to the inner side of the closed tube 3. A sealing plate 5 is fixedly connected to the bottom end of the feeding tube 4. A feeding hole 6 is opened on the circumference of the bottom side wall of the feeding tube 4. A matching pressing plate 7 is slidably connected inside the feeding tube 4. A blind plate 8 is fixedly connected to the top end of the pressing plate 7 through a connecting rod. A flange plate 9 is fixedly connected to the top end of the feeding tube 4. The blind plate 8 is fixedly installed to the flange plate 9 by a first fixing bolt 10. A round hole for the first fixing bolt 10 to pass through is opened on the blind plate 8. A threaded hole for the first fixing bolt 10 to be threadedly connected is opened on the flange plate 9. A stop ring 11 is fixedly connected to the closed tube 3.

[0025] The feeding pipe 4 is set inside the closed pipe 3 and sealed by the pressure plate 4. The closed pipe 3 is slidably connected to the hollow shaft 2, so it can be directly inserted into the reaction solution inside the reactor 1. By lifting the closed pipe 3, the feeding hole 6 is opened, so as to feed the material under the liquid surface, effectively avoiding the problem of liquid splashing caused by the fixed material falling directly onto the liquid inside the reactor 1 during feeding.

[0026] The top circumferential thread of the hollow shaft 2 is connected to a second fixing bolt 12. The second fixing bolt 12 is inserted into the hollow shaft 2 and abuts against the outer wall of the closed tube 3. The side wall of the hollow shaft 2 is provided with a threaded hole for threaded connection of the second fixing bolt 12.

[0027] The top of the closed tube 3 is circumferentially threaded with a third fixing bolt 13. The third fixing bolt 13 is inserted into the closed tube 3 and abuts against the outer wall of the feeding tube 4. The side wall of the closed tube 3 is provided with a threaded hole for threaded connection of the third fixing bolt 13.

[0028] The closed tube 3 is fixed to the hollow shaft 2 by the second fixing bolt 12, and the feeding tube 4 is fixed to the closed tube 3 by the third fixing bolt 13. The pressure plate 7 is fixed by the first fixing bolt 10 in conjunction with the flange plate 9, the blind plate 8 and the connecting rod, so that the position of the closed tube 3 relative to the hollow shaft 2 and the position of the feeding tube 4 relative to the closed tube 3 are fixed, thereby facilitating the feeding operation.

[0029] A stirring blade 22 is fixedly connected to the outer side of one end of the hollow shaft 2 that is inserted into the reactor 1.

[0030] A first synchronous pulley 14 is fixedly connected to one end of the hollow shaft 2 that extends out of the reactor 1. A second synchronous pulley 15 is provided on the outside of the first synchronous pulley 14. The second synchronous pulley 15 is fixedly installed at the output end of the drive motor 16. The drive motor 16 is externally connected to a power supply and a switch. The drive motor 16 is fixedly installed on the side wall of the reactor 1. The second synchronous pulley 15 is connected to the first synchronous pulley 14 through a synchronous belt 17.

[0031] The second synchronous pulley 15 is driven to rotate by the drive motor 16, which in turn drives the first synchronous pulley 14 through the synchronous belt 17, thereby driving the hollow shaft 2 to rotate. This, in turn, stirs the reaction inside the reactor 1 through the stirring blades 22, accelerating the reaction.

[0032] A filling port 18 is provided on one side of the top of the reactor 1, and a sealing cover 19 is installed on the top of the filling port 18.

[0033] The initial liquid reactant can be added through the filling port 18, and then sealed with the sealing cap 19.

[0034] The hollow shaft 2, the closed tube 3, and the feeding tube 4 are all provided with guide grooves 20 on their inner sides. The closed tube 3, the feeding tube 4, and the pressing plate 7 are all fixedly connected with guide bars 21 on their outer sides. The guide bars 21 are inserted into the guide grooves 20 and are slidably connected.

[0035] The guide bar 21 and the guide groove 20 work together to form a sliding guide and rotation limit, so that while the hollow shaft 2 drives the stirring blade 22 to rotate and stir, the feeding pipe 4 rotates to form centrifugal feeding.

[0036] The working principle of this utility model is as follows:

[0037] In use, liquid reactants are added to the reactor 1 through the filling port 18, and the filling port 18 is sealed with the sealing cap 19. Then, solid reactants are added to the feeding pipe 4. The pressure plate 7 is then inserted into the feeding pipe 4 until the blind plate 8 is in contact with the flange plate 9. The flange plate 9 and the blind plate 8 are then fixed together using the first fixing bolt 10. At this point, the pressure plate 7 is suspended above the solid reactants inside the feeding pipe 4 by the blind plate 8 via the connecting rod. The second fixing bolt 12 is then loosened, and the sealing pipe 3 is inserted into the reactor 1 until the stop ring 11 abuts against the top of the hollow shaft 2. The feeding pipe 4 is then further supported, and the third fixing bolt 13 is loosened, allowing the sealing pipe 3 to be inserted upwards. Lift the tube until the feeding hole 6 is exposed. Then, tighten the second fixing bolt 12 and the third fixing bolt 13 to fix the closed tube 3 to the hollow shaft 2 and the feeding tube 4 to the closed tube 3. Start the drive motor 16 to drive the second synchronous wheel 15 to rotate, which in turn drives the first synchronous wheel 14 through the synchronous belt 17, thereby driving the hollow shaft 2 to rotate. The stirring blades 22 stir the mixture inside the reactor 1, accelerating the reaction. The guide bar 21 and the guide groove 20 work together to form a sliding guide and rotation limit. So, while the hollow shaft 2 drives the stirring blades 22 to rotate and stir, the feeding tube 4 rotates to form centrifugal feeding.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
