Specific embodiments
[0026] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.
[0027] As Figures 2 - 5 shown, a reaction kettle applied to the carboxymethyl starch sodium process includes a reaction kettle body 1, a kettle cover 2, a ball valve 3, a stirring paddle 4 and a reduction motor 5. The kettle cover 2 is installed on the top of the reaction kettle body 1, the ball valve 3 is installed at the bottom of the reaction kettle body 1, the stirring paddle 4 is arranged inside the reaction kettle body 1 and spirally extends along the inner wall of the reaction kettle body 1 to the inside of the ball valve 3, and the stirring paddle 4 is controlled to rotate by the reduction motor 5.
[0028] Among them, the material processed inside the reaction kettle body 1 is soluble starch, and the soluble starch is preferably carboxymethyl starch sodium.
[0029] Specifically, the stirring paddle 4 arranged along the inner wall of the reaction kettle body 1 and spirally is close to the inner wall of the reaction kettle body 1 and extends to the bottom of the reaction kettle body 1, so as to stir the materials in each area inside the reaction kettle body 1, enabling the materials to fully react with each other and not easily causing caking and saccharification phenomena.
[0030] Furthermore, the ball valve 3 at the bottom of the stirring paddle 4 is convenient to open, which is beneficial to the rapid discharging of the materials inside the reaction kettle body 1.
[0031] Compared with the prior art, the stirring paddle 4 arranged spirally along the inner wall of the reactor body 1 enables the materials in various regions inside the reactor body 1 to be fully stirred and reacted, and it is not easy to appear caking and saccharification phenomena. Secondly, the ball valve 3 below the stirring paddle 4 is convenient to open, which is beneficial to the rapid discharging of the materials inside the reactor body 1.
[0032] The stirring paddle 4 includes a stirring main shaft 41, a fixing rod 42, stirring paddle blades 43 and a stirring sub-paddle 44. The stirring main shaft 41 is arranged in the middle inside the reactor body 1. The fixing rod 42 is perpendicular to the stirring main shaft 41 and is symmetrically arranged left and right with the stirring main shaft 41 as the central axis. The fixing rod 42 gradually shortens from top to bottom, and both ends of the fixing rod 42 are connected to the stirring paddle blades 43.
[0033] The stirring sub-paddle 44 is located at the bottom of the stirring paddle blades 43. The gap between the stirring sub-paddle 44 and the sphere 31 is 3 - 10 mm, and the gap between the stirring sub-paddle 44 and the sphere 31 is adjusted according to the material characteristics. For example, if the material inside the reactor body 1 is modified starch, the gap between the stirring sub-paddle 44 and the sphere 31 is adjusted to 5 mm.
[0034] An arc-shaped part 441 is formed at the bottom of the stirring sub-paddle 44. The arc-shaped part 441 fits the arc surface of the sphere 31. The structure of the arc-shaped part 441 enables the stirring sub-paddle 44 not to interfere with the sphere 31 during the rotation process.
[0035] The stirring main shaft 41, the fixing rod 42, the stirring paddle blades 43 and the stirring sub-paddle 44 are connected by welding. Welding makes the stirring main shaft 41, the fixing rod 42, the stirring paddle blades 43 and the stirring sub-paddle 44 integrated, which is convenient for the installation of the stirring paddle 4 inside the reactor body 1.
[0036] Specifically, the fixing rods 42 are symmetrically arranged left and right on the stirring main shaft 41. Correspondingly, the stirring paddle blades 43 at both ends of the stirring main shaft 41 are also symmetrically arranged. During the rotation of the stirring paddle blades 43, the materials inside the reactor body 1 can be lifted from bottom to top or lowered from top to bottom, so that the materials are evenly stirred.
[0037] The successive shortening of the fixing rods 42 inside the reactor body 1 makes the stirring paddle blades 43 arranged on the fixing rods 42 more conform to the shape of the reactor body 1.
[0038] Among them, a gap is left between the stirring sub-paddle 44 and the sphere 31 to avoid the contact between the stirring sub-paddle 44 and the sphere 31, which affects the use of both. And the smaller gap between the stirring sub-paddle 44 and the sphere 31 is to reduce the materials retained between the stirring sub-paddle 44 and the sphere 31 and avoid the insufficient reaction of the bottom materials.
[0039] The stirring paddle 4 composed of the stirring main shaft 41, fixed rod 42, stirring paddle blades 43 and stirring auxiliary paddle 44 in the utility model makes the materials in the reaction kettle body 1 be stirred more evenly and can react more fully. Secondly, it is also convenient for the installation of the stirring paddle 4.
[0040] The ball valve 3 includes a ball 31, valve seat 32, valve rod 33 and seal 34. The ball 31 is located inside the valve seat 32, and the valve rod 33 controls the rotation of the ball 31.
[0041] The seal 34 is located inside the valve seat 32. The seal 34 is arranged at the junction of the ball 31, valve seat 32 and stirring paddle blade 43 to prevent materials from entering the ball valve 3. At the same time, the seal 34 is also located between the ball 31, valve seat 32 and the material pipeline 10 to prevent materials from entering between the ball 31 and valve seat 32 and affecting the operation of the ball valve 3.
[0042] Furthermore, the diameter of the outlet of the ball valve 3 leading to the material pipeline 10 is larger than that of Figure 1 the existing technology. In the actual implementation process, the material discharging time in the existing technology is 130 - 150 s, and the material discharging time in this embodiment is about 80 s.
[0043] Specifically, when the valve rod 33 does not rotate, the ball 31 does not rotate either. Under the action of the ball 31, valve seat 32 and seal 34, the materials at the upper end of the ball valve 3 do not enter the ball valve 3 and are only stirred in the reaction kettle body 1; when the valve rod 33 rotates, the ball 31 rotates, and the fully reacted materials pass through the ball 31 and enter the material pipeline 10. At the same time, due to the existence of the seal 34 between the ball 31 and the material pipeline 10, the materials will not enter the ball valve 3 either, which is beneficial to the normal operation of the ball valve 3.
[0044] Compared with the existing technology, in the utility model, the diameter of the outlet of the ball valve 3 leading to the material pipeline 10 is larger, which is convenient for the smooth discharge of the reacted materials and the discharging speed is fast.
[0045] The kettle cover 2 includes a feeding pipe 21. The feeding pipe 21 is located at the upper end of the kettle cover 2 and is higher than the kettle cover 2, which is convenient for material feeding; and since the feeding pipe 21 is relatively high, the materials inside the reaction kettle body 1 are not easily ejected from the reaction kettle body 1, enabling the materials in the reaction kettle body 1 to react fully.
[0046] An installation plate 8 is fixed on the top of the kettle cover 2. A fixing member 9 is arranged between the reduction motor 5 and the installation plate 8. The fixing member 9 is used to support the reduction motor 5. The reduction motor 5 and the stirring paddle 4 are connected by a coupling 6. A bearing seat 7 is arranged between the stirring paddle 4 and the installation plate 8, and a bearing is arranged inside the bearing seat 7.
[0047] The bottom of the ball valve 3 is also connected with a material pipeline 10. The material pipeline 10 is used to transport the reacted materials inside the reaction kettle body 1.
[0048] Specifically, the reduction motor 5 is connected to the stirring paddle 4 through the coupling 6. The rotation of the reduction motor 5 causes the stirring paddle 4 to rotate as well. The bearing block 7 provided between the stirring paddle 4 and the mounting plate 8 plays a role in supporting and guiding the stirring main shaft 41 of the stirring paddle 4, enabling the stirring main shaft 41 to rotate stably.
[0049] Specifically implement a reactor applied to the sodium carboxymethyl starch process:
[0050] Feed materials from the feeding pipe 21. Turn on the reduction motor 5. The rotation of the motor shaft of the reduction motor 5 drives the stirring paddle 4 to rotate. Correspondingly, the materials in the reactor body 1 are fully reacted after being stirred by the stirring paddle 4. Rotate the valve stem 33, and the reacted materials are discharged from the sphere 31 and conveyed through the material pipeline 10.

Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
