DETAILED DESCRIPTION

[0025] The following is a specific description of the utility model.

[0026] Example 1

[0027] This embodiment provides a reaction kettle for producing calcipotriol liniment, such as Figure 1-3 As shown, it includes a tank body 1 with a feed inlet 102 and a discharge port 103, a feed pipe 304 is rotatably arranged inside the tank body 1, the feed pipe 304 has a plurality of openings distributed along its extension direction, a pressure valve 305 is installed in each opening, a feeding mechanism 4 connected to the feed pipe 304 is arranged on the tank body 1, and a pressure relief valve 101 is also arranged on the top of the tank body 1.

[0028] The above reactor is applicable to but not limited to the production of calcipotriol ointment. The feed port 102 on the tank body 1 is used to add basic raw materials, and the discharge port 103 is used to output the finished product. When the reactor is working, the additives or catalysts to be added later are sent into the feed pipe 304 through the feeding mechanism 4, and the raw materials are evenly dispersed to various places inside the reactor through the openings distributed on the feed pipe 304, so that the raw materials are evenly added to the reactor, and the subsequent sequential addition of different raw materials is realized; the feed pipe 304 is rotated to expand the distribution range of the added raw materials inside the reactor, and the feed pipe 304 can also play a stirring role, so that the raw materials inside the reactor are evenly and quickly mixed; the working principle of the pressure valve 305 is mainly based on the principle of balance between the liquid pressure and the spring force acting on the valve core. When the pressure inside the feed pipe 304 increases, the pressure acting on the valve core increases, pushing The valve core moves to change the opening of the valve port, thereby controlling the pressure of the system. Conversely, when the pressure inside the feed pipe 304 decreases, the spring force pushes the valve core back to its original position and restores the original opening of the valve port, so that the opening and closing of the pressure valve 305 can be controlled by the pressure inside the feed pipe 304; the setting of the pressure valve 305 is such that when the pressure inside the feed pipe 304 is greater than the set pressure of the pressure valve 305, the pressure valve 305 is opened to connect the inside and outside of the feed pipe 304. The setting of the pressure valve 305 can prevent the raw materials inside the tank body 1 from flowing back into the inside of the feed pipe 304 through the opening; the above setting can make the raw materials inside the reactor react evenly, thereby improving the quality of the finished products produced by the reactor; the pressure inside the closed reactor will increase with the addition of raw materials, and the pressure inside the tank body 1 can be released through the pressure relief valve 101, so that the pressure inside the tank body 1 remains stable, thereby ensuring the stable reaction of the raw materials and further improving the quality of the finished products produced by the reactor.

[0029] A further improvement is, Figure 2 and 3 As shown, the top of the tank body 1 is connected to a vertically arranged upper rotating shaft 302 through a bearing, and the tank body 1 is fixedly connected to a motor 301 that is transmission-connected to the upper rotating shaft 302. The upper rotating shaft 302 is a tubular structure that connects the inside and outside of the tank body 1. The bottom end of the upper rotating shaft 302 is connected to the first end of the material delivery pipe 304, and there are at least two material delivery pipes 304 evenly distributed around the axis of the upper rotating shaft 302. The upper rotating shaft 302 is driven to rotate by the motor 301, so that the material delivery pipe 304 is driven to rotate around the rotating shaft 302 through the upper rotating shaft 302; a sealing ring is arranged between the upper rotating shaft 302 and the tank body 1 to ensure the sealing effect of the tank body 1; the upper rotating shaft 302 is a tubular structure, so that the feeding mechanism 4 can deliver the raw materials to the inside of the material delivery pipe 304 through the upper rotating shaft 302, reducing the additional pipeline arrangement and reducing the production cost of the reactor.

[0030] A further improvement is, Figure 2 and3 As shown, one of the openings on the same feed pipe 304 is an emptying port, which is opened at the lowest level of the feed pipe 304. The raw materials inside the feed pipe 304 will gather at the emptying port under the action of gravity, so that the raw materials can be completely emptied through the emptying port through the high pressure inside the feed pipe 304, thereby reducing the accumulation of raw materials inside the feed pipe 304, improving the accuracy of adding raw materials inside the reactor, and facilitating the cleaning of the feed pipe 204.

[0031] A further improvement is, Figure 2 and 3 As shown, the opening pressure of the pressure valve 305 connected to the evacuation port is lower than the opening pressure of the other pressure valves 305. In the above reactor, the opening and closing of each pressure valve 305 can be controlled by controlling the pressure inside the feeding pipe 304. When the raw material inside the feeding pipe 304 is less, the pressure inside the feeding pipe 304 can be reduced to close the other pressure valves 305, leaving only the pressure valve 305 at the evacuation port open. In this way, while the raw material inside the feeding pipe 304 is discharged, it can prevent excessive air from being sent into the tank body 1 through the other openings, thereby ensuring the reaction effect of the raw material inside the reactor.

[0032] A further improvement is, Figure 4-6 As shown, the feeding mechanism 4 includes a sealing sleeve 401 coaxially sleeved on the outer periphery of the upper rotating shaft 302, both ends of the sealing sleeve 401 are slidingly sealedly connected to the upper rotating shaft 302 through sealing rings 405, the upper rotating shaft 302 is provided with a slot 310, the slot 310 is located between the two sealing rings 405, the sealing sleeve 401 is connected to the outlet of the pressure pump 402, the inlet of the pressure pump 402 is connected to the feed pipe 404, and the feed pipe 404 is equipped with a second valve 403. The pressure pump 402 provides power, and the raw materials are sucked through the feed pipe 404. The raw materials then enter the enclosed space between the upper rotating shaft 302 and the sealing sleeve 401, and then enter the interior of the upper rotating shaft 302 through the notch 310, and finally enter the delivery pipe 304. The second valve 403 is set to control the opening and closing of the feed pipe 404; the sealing sleeve 401 and the upper rotating shaft 302 are connected by the sliding seal of the sealing sleeve 401, so that the upper rotating shaft 302 can realize normal delivery of the raw materials while rotating; the pressure pump 402 is a water-gas dual-purpose pump. When the raw material delivery is completed, the pressure pump 402 can continue to input air into the delivery pipe 304 to maintain stable control of the internal pressure of the delivery pipe 304.

[0033] A further improvement is, Figure 2 and 3As shown, a heating ring 303 is sleeved on the outer circumference of the upper rotating shaft 302, and the heating ring 303 is located inside the tank body 1. The setting of the heating ring 303 can preheat the raw materials passing through the upper rotating shaft 302, thereby ensuring the stability of the reaction temperature inside the tank body 1 and improving the quality of the finished product produced by the reactor.

[0034] A further improvement is, Figure 2 and 3 As shown, the bottom of the tank body 1 is connected to a lower rotating shaft 308 through a bearing. The lower rotating shaft is a tubular structure connecting the inside and outside of the tank body 1. The lower rotating shaft 308 is coaxially arranged with the upper rotating shaft 302. The second end of the feed pipe 304 is connected to the lower rotating shaft 308. The lower rotating shaft 308 is installed with a first valve 309. A collecting box 2 connected to the bottom end of the feed pipe 304 is arranged below the tank body 1. A sealing ring is arranged between the lower rotating shaft 308 and the tank body 1 to seal to prevent leakage of the tank body 1; the upper rotating shaft 302 and the lower rotating shaft 308 fix the two ends of the feed pipe 304 respectively to improve the stability of the feed pipe 304 when rotating; when the first valve 309 on the lower rotating shaft 308 is closed, the raw material is fed into the feed pipe 304 and then enters the inside of the tank body 1. When the reactor needs to be cleaned, the first valve 309 can be opened so that the feed pipe 404 is directly connected to the lower rotating shaft 308. At this time, cleaning materials can be fed into the feed pipe 404. Water is used to clean the entire conveying channel of the raw material, and finally the cleaned water is discharged from the bottom end of the lower rotating shaft 302 to the inside of the collecting box 2 for collection. In this way, the raw material conveying pipeline can be cleaned separately, so that the cleaning of the feed pipe 304 can also be completed when the reactor is working normally. When inputting clean water, it is necessary to ensure that the water pressure is less than the opening pressure of each pressure valve 305; and by controlling the temperature of the clean water passing through the feed pipe 304, the temperature of the feed pipe 304 can be adjusted, thereby realizing the adjustment of the reaction temperature inside the reactor.

[0035] A further improvement is, Figure 2 and 3 As shown, two feed pipes 404 are provided, and both feed pipes 404 are installed with second valves 403, and both are connected to the inlet of the pressure pump 402. The second valve 403 can control the switching of the two feed pipes 404, and one of the feed pipes 404 can be connected to the raw material, and the other feed pipe can be connected to clean water, so as to realize the rapid switching between the two functions of adding raw materials and cleaning the feed pipe 304.

[0036] A further improvement is, Figure 2 and 3As shown, a propeller 307 is fixedly connected to the lower rotating shaft 308, and a plurality of porous plates 306 are fixedly connected between the upper rotating shaft 302 and the lower rotating shaft 308. The porous plates 306 are evenly distributed around the axis of the upper rotating shaft 302 and are parallel to the axis of the upper rotating shaft 302. The porous plates 306 and the propeller 307 can be driven to rotate by the upper rotating shaft 302, thereby achieving stirring of the raw materials inside the tank body 1, improving the uniformity of the raw material mixing, and ultimately improving the quality of the finished product produced by the reactor.
