Technical Field
[0001] This utility model relates to the technical field of waterborne polyurethane emulsion processing, and in particular to a reaction vessel for emulsion processing. Background Technology
[0002] Waterborne polyurethane emulsion is a new type of polyurethane liquid material that uses water instead of organic solvents as the dispersion medium. Waterborne polyurethane has good safety and low pollution, and also has advantages such as excellent mechanical properties, good compatibility, and easy modification.
[0003] When processing waterborne polyurethane emulsions, it is necessary to emulsify and stir the mixed solution in a reaction vessel. However, the existing reaction vessels have relatively simple stirring structures, which mostly use a single stirring rod to drive multiple stirring blades in the middle to stir the solution. This stirring structure is not effective enough in stirring the mixed solution, resulting in insufficient and uneven mixing, which affects the processing quality of the emulsion. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a reaction vessel for emulsion processing that can improve the stirring effect of mixed solutions, make the solutions mix more thoroughly and evenly, and effectively improve the quality of emulsion processing.

Four sets of support legs are fixedly connected at equal intervals in a ring at the bottom of the reaction vessel body. A feeding port is provided at the top of the reaction vessel body, and a material cover is installed on the feeding port. A drain pipe is connected to the lower right side of the reaction vessel body, and a valve is installed on the drain pipe. The stirring mechanism includes a motor.

A transmission rod is rotatably fitted in the middle of the transmission crankshaft. A sliding hole is provided in the center of the top of the reaction vessel body. A movable rod is slidably installed, with a hinge seat fixedly connected to the top of the movable rod. The bottom end of the transmission rod is rotatably connected to the hinge seat, and a tumbling disc is fixedly connected to the bottom end of the movable rod. The stirring mechanism includes two sets of fixed plates. Worm shaft sections are integrally fixed on the outer walls of both sides of the transmission crankshaft. The two sets of fixed plates are symmetrically fixedly connected to the inner sides of the two sets of vertical plates. Two sets of stirring rods are symmetrically rotatably connected to the bottom ends of the two sets of fixed plates. The four sets of stirring rods are symmetrically rotatably installed on the top of the reactor body. Worm wheels are fixedly sleeved on the four sets of stirring rods near the fixed plates, and the four sets of worm wheels are symmetrically meshed on both sides of the two sets of worm shaft sections. Multiple sets of stirring blades are fixedly connected at equal intervals on the outer walls of the four sets of stirring rods, and the stirring blades are located inside the reactor body.
[0006] Preferably, the rear end of the material cover is connected to the top end of the reactor body by two hinges. The material cover is rotated and mounted on the feeding port by the hinges. The front end of the material cover is fitted with a locking buckle between it and the front outer wall of the reactor body.

[0012] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0013] Example Please see Figures 1-4 This utility model discloses a reaction vessel for emulsion processing, comprising a reaction vessel body 1, a motor 6, and two sets of fixing plates 14. Four sets of support legs 2 are fixedly connected at equal intervals in a ring at the bottom of the reaction vessel body 1. A feeding port is provided at the top of the reaction vessel body 1, and a material cover 3 is installed on the feeding port. A drain pipe 4 is connected to the lower right side of the reaction vessel body 1, and a valve 5 is installed on the drain pipe 4. Two sets of vertical plates 7 are symmetrically fixedly connected to the top of the reaction vessel body 1. The motor 6 is fixedly installed on the outside of one set of vertical plates 7. A transmission crankshaft 8 is rotatably mounted on both sets of vertical plates 7, and the right end of the transmission crankshaft 8 is connected to the output of the motor 6. The transmission crankshaft 8 is fixedly connected at the end, and a transmission rod 9 is rotatably mounted in the middle. A sliding hole is opened in the center of the top of the reactor body 1, and a movable rod 10 is slidably installed in the sliding hole. The top end of the movable rod 10 is fixedly connected to a hinge seat 11, and the bottom end of the transmission rod 9 is rotatably connected to the hinge seat 11. A stirring plate 12 is fixedly connected to the bottom end of the movable rod 10. Worm shaft sections 13 are integrally fixed on the outer walls of both sides of the transmission crankshaft 8. Two sets of fixed plates 14 are symmetrically fixedly connected to the inner sides of two sets of vertical plates 7. Two sets of stirring rods 15 are symmetrically rotatably connected to the bottom ends of the two sets of fixed plates 14, and four sets of stirring rods 15 are rotatably connected to each other. The stirring rods 15 are symmetrically rotated and mounted on the top of the reactor body 1. Worm gears 16 are fixedly fitted onto each of the four stirring rods 15 near the fixed plate 14, and the four worm gears 16 are symmetrically meshed on both sides of the two worm shaft sections 13. Multiple stirring blades 17 are equidistantly fixed to the outer walls of the four stirring rods 15, and the stirring blades 17 are located inside the reactor body 1. In use, by opening the material cover 3, the raw materials for preparing the waterborne polyurethane emulsion and water are added to the reactor body 1 to form a mixed solution. Then, the material cover 3 is closed, and by starting the motor 6, the stirring plate 12 can be stirred. The reciprocating movement of the stirring rod 15 also allows it to rotate. The reciprocating movement of the tumbling disc 12 tumbles the mixed solution. The rotation of the stirring rod 15 drives the stirring blades 17 to stir the mixed solution. With the continuous tumbling of the tumbling disc 12, the stirring blades 17 continuously stir the mixed solution. The stirring rod 15 is distributed around the inside of the reaction vessel 1, which can expand the stirring range of the mixed solution, thereby improving the stirring effect, making the solution more fully and evenly mixed, and effectively improving the processing quality of the emulsion.
[0014] Two hinges 18 are connected between the rear end of the material cover 3 and the top end of the reactor body 1. The material cover 3 is rotated and mounted on the feeding port through the hinges 18. A latch 19 is provided between the front end of the material cover 3 and the front outer wall of the reactor body 1. In use, the latch 19 makes it easier to open and close the material cover 3.
[0015] An observation port is provided on the material cover 3, and an observation window 20 is fixedly installed inside the observation port; by setting the observation window 20, it is convenient to observe the mixing of the solution in the reaction vessel 1 so that the solution can be discharged in time.
[0016] A reinforcing plate 21 is fixedly connected between the outer side of the two sets of vertical plates 7 and the top of the reactor body 1; by setting the reinforcing plate 21, the connection between the vertical plate 7 and the reactor body 1 can be made more firm and stable.
[0017] A sliding sleeve 22 is fixedly fitted into the sliding hole at the center of the top of the reactor body 1. The movable rod 10 is slidably mounted on the top of the reactor body 1 by cooperating with the sliding sleeve 22. By setting the sliding sleeve 22, the movable rod 10 can slide more smoothly on the reactor body 1.
[0018] This utility model discloses a reaction vessel for emulsion processing. Its working principle is as follows: During use, the material cover 3 is opened, and raw materials for preparing waterborne polyurethane emulsion and water are added into the reaction vessel body 1 to form a mixed solution. The material cover 3 is then closed, and the motor 6 is started. The motor 6 drives the transmission crankshaft 8 to rotate. The transmission crankshaft 8, through the connection between the transmission rod 9 and the hinge seat 11, drives the movable rod 10 to slide up and down reciprocally. This, in turn, causes the movable rod 10 to drive the stirring disc 12 to move up and down reciprocally inside the reaction vessel body 1. While the transmission crankshaft 8 is rotating, it also moves through the worm shaft section 1... The meshing of the worm gear 16 with the stirring rod 15 drives the stirring rod 15 to rotate. The stirring plate 12 moves up and down to stir the mixed solution. The rotation of the stirring rod 15 causes the stirring blade 17 to stir the mixed solution. Under the continuous stirring of the stirring plate 12, the stirring blade 17 continuously stirs the mixed solution. The stirring rod 15 is distributed around the inside of the reaction vessel 1, which expands the stirring range of the mixed solution and makes the solution fully and evenly mixed. After the stirring process is completed, the valve 5 is opened and the solution is discharged through the drain pipe 4.
[0019] The reaction vessel for emulsion processing of this utility model has common mechanical installation, connection and setting methods, and can be implemented as long as it can achieve its beneficial effect. The valve 5, motor 6, hinge 18 and lock 19 of the reaction vessel for emulsion processing of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.
[0020] 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 technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
