DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range protected by the utility model.

[0030] The core of the utility model is to provide a kind of double shaft rotary type reaction kettle, by adopting double motor drive kettle body rotation along the axis of two directions, make solute and solvent produce turbulent flow in kettle body, by the density difference of solute and solvent, make it obtain different acceleration, and then increase the relative speed of both, improve the scouring, washing effect of solvent to solute.

[0031] Please refer to Figure 1 A kind of double shaft rotary type reaction kettle, comprising:

[0032] Kettle body;

[0033] First motor 6, its output shaft is connected with kettle body power, for driving kettle body rotation along first axis 18;

[0034] Second motor 17, its output shaft is connected with kettle body and the combination of first motor 6 power, for driving combination rotation along second axis 19, there is included angle between first axis 18 and second axis 19.

[0035] As Figure 1As shown, a first motor 6 drives the vessel body to rotate along the first axis 18, so that the solute and solvent inside the vessel body obtain a first rotational speed. Then, a second motor 17 drives the vessel body to rotate along the second axis 19, so that the solute and solvent obtain a second rotational speed. Obtaining the second rotational speed helps to break the stable circular motion of the solute and solvent caused by the first rotational speed, thereby changing the acceleration of the solute and solvent. Since there is a difference in density between the solute and solvent, that is, the acceleration of the two is not equal, the speed difference between the two gradually increases, that is, the rinsing and washing effect of the two is enhanced.

[0036] In practical use, the first motor 6 can be used to drive the vessel to rotate to a set speed and maintain it for a set time. Then, the first motor 6 can be stopped. While the solvent and solute are still moving inside the vessel, the second motor 17 can be used to drive the vessel to continue rotating. The rotation axes of the two motors are different, so the speed and direction of the moving solute and solvent change, and there is a difference in their speeds, which effectively improves the rinsing and washing effect.

[0037] Similarly, in practical use, the first motor 6 and the second motor 17 can be used to drive the vessel to rotate synchronously along two axes, so that the solute and solvent form turbulence in the vessel, thereby utilizing the velocity difference caused by the different densities between the solute and solvent to improve the rinsing and washing effect of both.

[0038] In some embodiments, the first axis 18 is perpendicular to the second axis 19, and the first axis 18 and the second axis 19 intersect.

[0039] like Figure 1 As shown, the arrangement of the first axis 18 and the second axis 19 perpendicular and intersecting helps the solute and solvent to quickly form turbulence in the vessel, thereby improving the flushing and washing efficiency.

[0040] In some embodiments, the first axis 18 and the second axis 19 are arranged at an angle of 30°, 45°, 60°, etc., or the first axis 18 and the second axis 19 are straight lines in different planes and do not intersect, which also falls within the protection scope of this application.

[0041] In some embodiments, the output shaft of the first motor 6 is fixedly connected to the vessel body, and the output shaft of the second motor 17 is fixedly connected to the body of the first motor 6.

[0042] The first motor 6 is directly connected to the vessel body or connected through a reduction mechanism, that is, the first motor 6 directly drives the vessel body to rotate along the first axis 18; the second motor 17 is directly connected to the body of the first motor 6 or connected through a reduction mechanism, that is, the second motor 17 can drive the combination of the first motor 6 and the vessel body to rotate along the second axis 19.

[0043] This means that the first motor 6 and the second motor 17 simultaneously drive the vessel body to rotate along the first axis 18 and the second axis 19, which enables the solute and solvent in the vessel body to quickly form turbulence, thereby increasing the flushing and washing effect.

[0044] In some embodiments, a crank arm 11 is fixedly provided at the output shaft end of the second motor 17, and the end of the crank arm 11 is fixedly connected to the body of the first motor 6. The center of gravity of the crank arm 11, the first motor 6 and the vessel assembly is located on the second axis 19.

[0045] like Figure 1 As shown, the output end of the second motor 17 is directly connected to or connected to the crank arm 11 through a reduction mechanism, and the body of the first motor 6 is fixed to the lower section of the crank arm 11, so that the first motor 6 rotates around the second axis 19 as a whole.

[0046] Meanwhile, when designing the curved arm 11, the combined center of gravity of the curved arm 11, the first motor 6, and the vessel body is set on the second axis 19, which helps to ensure the dynamic balance of the second motor 17 when it rotates.

[0047] In some embodiments, the inner wall of the vessel is provided with a serrated plate 13;

[0048] like Figure 1 As shown, a serrated plate 13 is provided on the inner wall of the vessel. The inclined surface of the plate increases the probability of collision between the solute and solvent and the plate. At the same time, it increases the resistance when the solute and solvent move relative to the plate. The inclined surface of the plate also causes the solute and solvent to bounce in different directions after the collision, which increases the turbulence of the velocity and direction of the solute and solvent, thereby increasing the flushing effect of the solvent on the solute.

[0049] In some embodiments, a coil 15 is provided inside the vessel body, and a circulating water inlet 8 and a circulating water outlet 7 connecting the two ends of the coil 15 are provided on the vessel cover.

[0050] A coil 15 is installed inside the vessel, and a heat exchange medium, such as high-temperature steam or cooling water, is circulated inside it. When high-temperature steam is introduced, it heats the medium inside the vessel after circulating in the coil 15; when cooling water is introduced, it cools the medium inside the vessel after circulating in the coil 15.

[0051] In some embodiments, a liquid phase valve 4 and a gas phase valve 9 are provided on the vessel lid;

[0052] A rigid tube is installed inside the vessel, which connects the liquid phase valve 4 and the bottom of the vessel.

[0053] When some solutes and solvents are stirred, an oxidation reaction may occur due to the presence of oxygen in the vessel. Therefore, a liquid phase valve 4 and a gas phase valve 9 are installed on the vessel lid, and a rigid tube is used to directly connect the liquid phase valve 4 to the bottom of the vessel. This allows nitrogen or other inert gases to be directly injected into the liquid portion of the vessel through the liquid phase valve 4, replacing the original gas in the vessel and causing it to be discharged through the gas phase valve 9. This reduces the oxygen concentration in the vessel and prevents the oxidation reaction from occurring.

[0054] In some embodiments, a vessel body jacket 14 is provided inside the vessel body, and a heating component is provided inside the vessel body jacket 14;

[0055] like Figure 1 As shown, during the stirring process, the vessel rotates in two directions. The heating method using coil 15 presents a problem with the piping arrangement at the rotation position. Therefore, the heating components are arranged in the form of a vessel jacket 14, preferably using electric heating. In the rotation position, a slip ring can be used for power transmission, thereby solving the wiring arrangement problem at the rotation position.

[0056] In some embodiments, an infrared thermometer 12 is also included for detecting the temperature of the vessel body;

[0057] like Figure 1 As shown, an infrared thermometer 12 is integrated into the equipment to measure the temperature of the vessel, thereby ensuring the accuracy of the reaction temperature in the vessel.

[0058] In some embodiments, the infrared thermometer 12 is arranged on the curved arm 11 and faces the vessel body without contacting it; in other embodiments, a temperature sensor is added to the inner cavity or outer wall of the vessel body to measure the temperature of the vessel body or the medium inside the vessel body, which also falls within the protection scope of this application.

[0059] In some embodiments, a feeding port 1 is provided on the lid of the vessel body, and a discharge valve 16 is provided at the bottom of the vessel body;

[0060] The vessel lid is equipped with a safety valve 3 and a pressure gauge 5;

[0061] The lid of the vessel is equipped with an observation window for observing the interior of the vessel.

[0062] The vessel body consists of two parts: a lid and a body, which are fixedly connected by a flange. A feeding port 1 is provided on the lid, and a discharge valve 16 is provided at the bottom of the body to facilitate the feeding and discharging of solvents and solutes.

[0063] Meanwhile, a safety valve 3 and a pressure gauge 5 are installed on the lid of the vessel to facilitate the detection of the internal pressure of the vessel. When the internal pressure exceeds the limit of the safety valve 3, it can automatically release pressure to ensure production safety.

[0064] Moreover, such as Figure 1As shown, the first observation window 2 and the second observation window 10 are respectively arranged at different positions of the kettle cover, so that the observation points are increased, and the reaction result of the material in the kettle body can be observed conveniently.

[0065] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between various embodiments can be referred to each other.
