Description

Technical Field

[0002] With the continuous development of the domestic economy and the gradual improvement of scientific and technological levels, domestic pharmaceutical production and biochemical industries are also developing continuously. In the preparation process of modern medicines, pharmaceutical intermediates, as an intermediate product in pharmaceutical preparation, are a necessary stage in turning modern chemical raw materials into medicines. In the preparation process of pharmaceutical intermediates, stirring equipment is often required to evenly mix the chemical raw materials used to synthesize pharmaceutical intermediates, thereby improving the reaction efficiency of chemical raw materials.

[0003] There are some defects in the mechanical stirring device for preparing Chinese medicine intermediates in the prior art. First, the viscosity of most pharmaceutical mixtures in the stirring tank is relatively high. When the existing stirring roller is stirring, it is unable to drive the upper and lower layers of materials in the stirring tank to mix quickly, which affects the actual mixing efficiency and effect. At the same time, since most pharmaceutical mixtures have a relatively high viscosity, when the mixed pharmaceutical intermediates are discharged from the tank, a large amount of pharmaceutical intermediates will remain inside the tank and on the stirring roller, making it difficult to discharge the tank. If not cleaned in time, the remaining pharmaceutical intermediates will deteriorate, affecting the reuse of the device. Summary of the invention

A right stirring shaft 20 is fixedly connected to the middle part of the right bevel gear 19, and a spiral blade 21 is fixedly connected to the lower part of the right stirring shaft 20. The bottom end of the right stirring shaft 20 is movably sleeved to a connecting seat, and its function is to drive the left stirring shaft 15 and the stirring blade 16 to rotate through the driving motor 10, thereby driving the pharmaceutical intermediate raw materials on the upper layer of the stirring shell 6 to move to the bottom, and at the same time drive the right stirring shaft 20 and the spiral blade 21 to rotate, thereby driving the pharmaceutical intermediate raw materials at the bottom of the stirring shell 6 to move to the upper layer, and the stirring shell 6 swings, so that the pharmaceutical intermediate raw materials are quickly mixed and evenly mixed, thereby solving the problem that the existing stirring roller cannot drive the upper and lower layers of materials inside the stirring tank to mix quickly when stirring, affecting the actual mixing efficiency and effect.

The function of the compression springs 34 is to swing the stirring shell 6, and at the same time, the lower surface of the elastic membrane 32 will contact the upper end of the stirring blade 16. Then, the stirring blade 16 slowly reverses, so that the elastic membrane 32 can move downward close to the stirring blade 16, thereby cleaning the residual pharmaceutical intermediate on the stirring blade 16. Similarly, the scraper 27 moves downward to clean the residual pharmaceutical intermediate on the spiral blade 21, so that no pharmaceutical intermediate remains in the stirring shell 6, the stirring blade 16 and the spiral blade 21, thereby solving the problem that due to the large viscosity of the pharmaceutical mixture, a large amount of pharmaceutical intermediate will remain in the tank body and the stirring roller after mixing, which is difficult to discharge from the tank body. If it is not cleaned in time, the residual pharmaceutical intermediate will deteriorate, affecting the reuse of the device.

[0024] Among them, the transmission shaft 11, the left stirring shaft 15, the I-shaped shaft 18, and the right stirring shaft 20 are all rotatably connected to the top cover 7. The top cover 7 is provided with an arc groove. The lower surface of the sealing cover 9 is adapted to and slidably connected to the arc groove. Its function is that the driving motor 10 drives the transmission shaft 11 to rotate, the transmission shaft 11 drives the upper gear 12 and the lower gear 13 to rotate, the upper gear 12 drives the left bevel gear 14 and the left stirring shaft 15 to rotate, the left stirring shaft 15 drives the stirring blade 16 to rotate, the lower gear 13 drives the I-shaped shaft 18 to rotate, the I-shaped shaft 18 drives the right bevel gear 19 and the right stirring shaft 20 to rotate, and the right stirring shaft 20 drives the spiral blade 21 to rotate.

[0025] Among them, the pitch of the spiral blade 21 and the stirring blade 16 are constant, the diameter of the spiral blade 21 is constant, the diameter of the stirring blade 16 changes from small to large from the bottom to the top, and the spiral rotation direction of the spiral blade 21 is opposite to that of the stirring blade 16. Its function is that the stirring blade 16 rotates, thereby driving the pharmaceutical intermediate raw materials on the upper layer of the stirring shell 6 to move to the bottom, and at the same time, the spiral blade 21 rotates, thereby driving the pharmaceutical intermediate raw materials at the bottom of the stirring shell 6 to move to the upper layer, thereby achieving rapid and uniform mixing of the upper and lower layers of pharmaceutical intermediate raw materials in the stirring shell 6.

[0026] Among them, the scraper block 27 is adapted to the spiral blade 21, the elastic membrane 32 is adapted to the stirring blade 16, the left side of the C-shaped frame 33 is adapted to the left stirring shaft 15, the elastic membrane 32 is made of elastic material, and the elastic membrane 32 is filled with gas. Its function is that during the downward movement of the elastic membrane 32, the left stirring shaft 15 will squeeze the C-shaped frame 33, so that the C-shaped frame 33 squeezes the compression spring 34, thereby expanding the elastic membrane 32 to the front and rear sides. When the elastic membrane 32 moves to the bottom, the pharmaceutical intermediates remaining on the stirring blade 16 are cleaned up and all fall to the bottom of the stirring shell 6. If there are pharmaceutical intermediates remaining on the surface of the elastic membrane 32, they will be thrown to the bottom of the stirring shell 6.

[0027] Working principle:

[0028] Before the present invention is used, the swing frame 2 is in a horizontal state, the right electromagnet 24 is energized to attract the right permanent magnet 25, thereby driving the scraper block 27 to be located at the upper end of the right chute 23, the left electromagnet 29 is energized to attract the left permanent magnet 30, thereby driving the sliding frame 31 to be located at the upper end of the left chute 28, and the discharge valve 22 is in a closed state;

[0029] Then, the sealing cover 9 is slid to open the feed port 8, and an appropriate amount of raw materials of the pharmaceutical intermediates are added into the interior of the stirring shell 6 through the feed port 8. The sealing cover 9 is slid to seal the feed port 8, and the rotating motor 5 is started to drive the driving gear 4 to rotate, and the driving gear 4 drives the rotating gear 3 and the swing frame 2 to rotate, so that the stirring shell 6 swings. When the stirring shell 6 swings, the angular velocity from the highest point to the lowest point gradually increases, and vice versa, the angular velocity gradually decreases;

[0030] At the same time, the driving motor 10 drives the transmission shaft 11 to rotate, the transmission shaft 11 drives the upper gear 12 and the lower gear 13 to rotate, the upper gear 12 drives the left bevel gear 14 and the left stirring shaft 15 to rotate, the left stirring shaft 15 drives the stirring blade 16 to rotate, thereby driving the pharmaceutical intermediate raw materials on the upper layer of the stirring shell 6 to move to the bottom, the lower gear 13 drives the I-shaped shaft 18 to rotate, the I-shaped shaft 18 drives the right bevel gear 19 and the right stirring shaft 20 to rotate, the right stirring shaft 20 drives the spiral blade 21 to rotate, thereby driving the pharmaceutical intermediate raw materials at the bottom of the stirring shell 6 to move to the upper layer, the stirring blade 16 and the spiral blade 21 rotate, and the stirring shell 6 swings periodically, so that the raw materials of the pharmaceutical intermediates can be fully stirred and mixed inside the stirring shell 6;

[0031] After the stirring is completed, the discharge valve 22 is opened, and the uniformly mixed pharmaceutical intermediate is discharged from the body. However, due to the high viscosity of the pharmaceutical intermediate, a certain amount of pharmaceutical intermediate will remain on the inner wall of the stirring shell 6, the stirring blade 16, and the surface of the spiral blade 21. The stirring shell 6 swings, and the left electromagnet 29 is energized in the reverse direction to repel the left permanent magnet 30, so that the left permanent magnet 30 drives the sliding frame 31, the elastic membrane 32, and the C-shaped frame 33 to move downward. The lower surface of the elastic membrane 32 will contact the upper end of the stirring blade 16, and then the stirring blade 16 slowly reverses, so that the elastic membrane 32 can move downward close to the stirring blade 16. When the elastic membrane 32 is located at the upper part of the stirring blade 16, the left electromagnet 29 is powered off, and the stirring blade 16 that continues to reverse will drive the elastic membrane 32 to move downward, thereby cleaning the pharmaceutical intermediate remaining on the stirring blade 16. In addition, the stirring blade 16 is in a swinging state. The state makes the residual pharmaceutical intermediate fall to the bottom of the stirring shell 6. During the downward movement of the elastic membrane 32, the left stirring shaft 15 will squeeze the C-shaped frame 33, so that the C-shaped frame 33 squeezes the compression spring 34, so that the elastic membrane 32 expands to the front and rear sides. When the elastic membrane 32 moves to the bottom, the residual pharmaceutical intermediate on the stirring blade 16 is cleaned and all falls to the bottom of the stirring shell 6. If there is any pharmaceutical intermediate remaining on the surface of the elastic membrane 32, it will be thrown to the bottom of the stirring shell 6, and the discharge valve 22 will be opened to discharge the residual pharmaceutical intermediate at the bottom of the stirring shell 6. After discharge, the discharge valve 22 closes the stirring blade 16 and rotates forward, driving the elastic membrane 32 to move upward. When the elastic membrane 32 is located at the top of the stirring blade 16, the left electromagnet 29 is energized to adsorb the left permanent magnet 30, thereby driving the sliding frame 31 to be located at the upper end of the left slide groove 28.

[0032] The right electromagnet 24 is energized in the reverse direction to repel the right permanent magnet 25, so that the right permanent magnet 25 drives the connecting block 26 and the scraping block 27 to move downward, and the lower surface of the scraping block 27 will contact the upper end of the spiral leaf 21, and then the spiral leaf 21 slowly reverses, so that the scraping block 27 can move downward close to the spiral leaf 21. When the scraping block 27 is located at the upper part of the spiral leaf 21, the right electromagnet 24 is powered off, and the spiral leaf 21 that continues to reverse will drive the scraping block 27 to move downward, thereby cleaning the pharmaceutical intermediates remaining on the spiral leaf 21, and in a swinging state, the pharmaceutical intermediates remaining on the upper surface fall to the bottom of the stirring shell 6. When the scraping block 27 moves to the bottom, the pharmaceutical intermediates remaining on the stirring leaf 16 are cleaned up and all fall to the bottom of the stirring shell 6, and the discharge valve 22 is opened to discharge the pharmaceutical intermediates remaining at the bottom of the stirring shell 6.
