DETAILED DESCRIPTION

[0023] The following is a specific description of the utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, a mixer for preparing calcipotriol ointment comprises a tank body 1 with an open top and a top cover 2 with a sealing cover arranged on the top of the tank body 1, a stirring paddle 305 is arranged inside the tank body 1, a power mechanism for driving the stirring paddle 305 to rotate is arranged on the top cover 2, a sealing sleeve of the stirring paddle 305 is provided with an elastic sealing bag 303, an air pump 201 connected to the inside of the sealing bag 303 is arranged on the top cover 2, and the air pump 201 is used to extract or fill the air inside the sealing bag 303.

[0026] The above-mentioned mixer is suitable for the production and preparation of calcipotriol ointment. The tank body 1 is used to contain the raw materials that need to be mixed. The top side of the tank body 1 is provided with a feed port for placing the raw materials, and the bottom of the tank body 1 is provided with a discharge port for sending out the mixed materials. The top cover 2 is a sealing cover provided on the tank body 1, and the top cover 2 can be opened and closed to realize the maintenance and repair of the internal components of the tank body 1; the stirring rod 305 can be rotated inside the tank body 1 to realize the stirring and mixing of the raw materials.

[0027] When the mixer is in use, when it is necessary to stir the raw materials, the air pump 201 works to extract the air inside the sealed bag 303. At this time, the sealed bag 303 is tightly attached to the outer surface of the stirring paddle 305 under the action of air pressure, which is equivalent to providing a protective layer on the outer surface of the stirring paddle 305. At this time, the structure of the stirring paddle 305 is the original structure and is not affected by the sealed sleeve 303. Therefore, the raw materials inside the tank body 1 can be stirred and mixed by the rotation of the stirring paddle 305. A valve can be provided in the communication channel between the air pump 201 and the sealed bag 303. By closing the valve, the low air pressure inside the sealed bag 303 can be maintained without the need for the air pump 201 to continue working. When the mixer is cleaned after the stirring is completed, the raw materials will adhere to the stirring paddle 305 because the stirring paddle 305 is wrapped by the sealed bag 303. The sealing bag 303 is on the surface of the sealing bag 303, but will not adhere to the surface of the stirring paddle 305. At this time, the air pump 201 fills air into the sealing bag 303 to expand the sealing bag 303. The surface of the expanded sealing bag 303 is smooth, and there is no cleaning dead angle, thereby improving the cleaning effect of the raw materials adhering to the sealing bag 303. The sealing bag 303 can be made of thermoplastic polyurethane film. The thermoplastic polyurethane film has high strength and excellent elasticity, can withstand large stretching and compression without being easy to break, and can improve the firmness of the sealing bag 303. A polytetrafluoroethylene layer can be provided on the surface of the sealing bag 303. Polytetrafluoroethylene has corrosion resistance, wear resistance and non-stick properties, which can further improve the strength of the sealing bag 303 and reduce the adhesion of raw materials on the sealing bag 303.

[0028] Compared with the stirring paddle 306 in the prior art, the sealing bag 303 can isolate the material and the stirring paddle 306 to keep the stirring paddle 306 clean, while protecting the stirring paddle 306 and extending the service life of the stirring paddle 306; by inflating and degassing the sealing bag 303, the original structure of the stirring paddle 306 can be maintained during stirring to ensure the stirring effect, and the cleaning dead corners of the stirring paddle 306 can be eliminated during cleaning to improve the cleaning effect; and in the process of expansion and contraction of the sealing bag 303, the raw materials adhering to the sealing bag 303 can be thrown off by inertia to improve the cleaning effect, thereby ultimately improving the mixing effect of the mixer.

[0029] A further improvement is, Figure 2-4As shown, the top cover 2 is rotatably connected to the drive shaft 203 through a bearing, the bottom end of the drive shaft 203 is horizontally fixedly connected to the cross beam 206, the top end of the drive shaft 203 is connected to the first driving member 202, and the stirring paddle 305 is installed on the cross beam 206; the top end of the stirring paddle 305 is vertically provided with a power shaft 301, the power shaft 301 is rotatably connected to the cross beam 206 through a bearing, and the cross beam 206 is provided with a second driving member 205 transmission-connected to the power shaft 301. In the above mixer, the drive shaft 203 is connected to the top cover 2 through a bearing, the power shaft 301 is connected to the end of the crossbeam 206 through a bearing, the first drive member 202 and the second drive member 205 both include a motor and a gear box, the drive shaft 203 or the power shaft 301 is connected to the driven gear of the gear box, and the driving gear of the gear box is connected to the output end of the motor, so that the drive shaft 203 or the power shaft 301 is driven by the motor to rotate; when the drive shaft 203 rotates, the crossbeam 206 drives the two stirring paddles 305 to revolve around the axis of the drive shaft 203, and when the power shaft 301 rotates, the stirring paddles 305 rotate around the axis of the power shaft 301; the stirring paddles 305 can stir the raw materials through the revolution, and the angle of the stirring paddles 305 can be adjusted through the rotation, thereby improving the stirring effect and ultimately improving the mixing effect of the mixer.

[0030] A further improvement is, Figure 4 and 5 As shown, the top of the stirring paddle 305 is fixedly connected to a fixing seat 304, and the fixing seat 304 is connected to a sealing plate 302 by bolts. The sealing sleeve 303 has a bag opening 308, and the edges of the bag opening 308 are arranged between the sealing plate 302 and the fixing seat 304. The sealing plate 302 and the fixing seat 304 clamp the bag opening 308 of the sealing sleeve 303 from both sides, thereby sealing the bag opening 308, and finally the sealing sleeve 303 seals the stirring paddle 305 inside, and ensures that no air leakage occurs during the inflation and deflation of the sealing sleeve 303; at the same time, the sealing plate 302 can be disassembled by bolts, thereby improving the convenience of replacing the sealing sleeve 303.

[0031] A further improvement is, Figure 2-4 As shown, the drive shaft 203 and the power shaft 301 are both tubular structures, and a connecting pipe 204 is provided between the drive shaft 203 and the power shaft 301. The air pump 201 is connected to the inside of the sealed bag 303 through the drive shaft 203, the connecting pipe 204 and the power shaft 301 in sequence. The power shaft 301 and the drive shaft 203 can be used to transport air while serving as rotating shafts, thereby eliminating the need for additional gas pipelines, reducing the occupation of the internal space of the mixer, and reducing the production cost of the mixer.

[0032] A further improvement is, Figure 4-6As shown, the stirring paddle 305 is a hollow flat plate structure, the power shaft 301 is connected to the inside of the stirring paddle 305, and a plurality of through holes 306 are evenly distributed on the outer surface of the stirring paddle 305. The hollow structure can reduce the weight of the stirring paddle 305, and the air enters the inside of the sealing bag 303 through each through hole 306 or is drawn out from the inside of the sealing bag 303. The setting of the plurality of through holes 306 can improve the efficiency and uniformity of the inflation and deflation of air; by passing cold air or hot air into the stirring paddle 305, the temperature of the material inside the tank body 1 can also be adjusted, thereby improving the practicality of the mixer.

[0033] A further improvement is, Figure 5 As shown, both sides of the stirring paddle 305 are provided with guide strips 307; the horizontal height of the guide strips 307 gradually decreases from the front end to the rear end. The angle of the stirring paddle 305 can be adjusted by the rotation of the stirring paddle 305, so that the horizontal flow direction of the material can be changed during the revolution of the stirring paddle 305; the setting of the guide strips 307 can change the vertical flow direction of the material when the material passes through the surface of the stirring paddle 305, thereby improving the stirring effect of the mixer on the material.

[0034] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
