Technical Field
[0001] The utility model relates to the technical field of mixers for raw materials of biological medical reagents, and particularly relates to a mixer for raw materials of biological medical reagents. Background Art
[0002] A mixing tank is a device for mixing various materials evenly. When mixing biological medical raw materials, a mixing tank is often used for mixing. The medical raw materials are poured into the interior of the mixing tank, and the stirring rod is started to mix the raw materials evenly.
[0003] The inventor found during daily use of the mixing tank that when mixing medical raw materials, some medical raw materials cannot have too high a temperature during mixing. Therefore, it is necessary to introduce cold air into the mixing tank for cooling. Since the air contains impurities such as dust, the impurities in the air will enter the interior of the mixing tank during mixing. As a result, after the medical raw materials are mixed well, there will be impurities such as dust inside, which will cause the mixed medical reagents to be unusable and thus have an impact. Content of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a mixer for raw materials of biological medical reagents is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A mixer for raw materials of biological medical reagents includes a mixing tank. A feeding frame is fixedly connected to the upper top of the mixing tank. A weighing device is arranged inside the feeding frame. An air pump is fixedly connected to the upper top of the mixing tank. The output end of the air pump is fixedly connected to an air ring. The air ring is fixedly connected to the upper top of the mixing tank. A motor is fixedly connected to the upper top of the air ring. The output end of the motor is fixedly connected to a stirring rod. A circular groove is opened inside the stirring rod. Through grooves are opened on the surface of the stirring rod. One end of the air pump is fixedly connected to an air inlet pipe. A filtering device is arranged inside the air inlet pipe. The filtering device includes a filter screen arranged inside the air inlet pipe.
[0006] The effects achieved by the above components are as follows: Under the action of the filter screen, large-particle impurities in the air can be filtered out, so that large-particle dust and other impurities will not enter the interior of the mixing tank. When it is necessary to mix medical raw materials, the medical raw materials are poured into the interior of the mixing tank through the feeding frame for even mixing. If cold air needs to be introduced into the medical raw materials, the air pump is started to make the gas enter the interior of the air ring. Under the action of the circular groove and the through holes, it enters the interior of the mixing tank for cooling, and thus the function of mixing medical raw materials is completed.
[0007] Preferably, a retaining ring is fixedly connected inside the air inlet pipe. A filter plate is arranged at one end of the retaining ring. A rectangular groove is formed in the inner wall of the air inlet pipe. A threaded rod is rotatably connected to the inner wall of the rectangular groove. A filter screen is threadedly connected to the surface of the threaded rod. Activated carbon is arranged inside the filter plate.
[0008] The effects achieved by the above components are as follows: Under the action of the filter plate and the activated carbon, small-particle dust is also blocked outside, thereby achieving the effect of filtering impurities in the air.
[0009] Preferably, a staple is fixedly connected to the side of the filter screen, and the staple is inserted into the filter plate.
[0010] The effects achieved by the above components are as follows: Under the action of the staple, the filter plate will not curl up inside the air inlet pipe, avoiding the phenomenon of incomplete filtration caused by curling up.
[0011] Preferably, a fixing rod is fixedly connected inside the rectangular groove, and the filter screen is slidably connected to the surface of the fixing rod.
[0012] The effects achieved by the above components are as follows: Under the action of the fixing rod, the filter screen will not rotate with the rotation of the threaded rod. When air needs to be introduced, the activated carbon is loaded into the filter plate, and the filter plate is installed on one side of the retaining ring on the inner wall of the air inlet pipe. The threaded rod is rotated to make the filter screen move towards the inside of the air inlet pipe. Under the action of the staple, the filter plate can be fixed between the retaining ring and the filter screen, avoiding the phenomenon of the filter plate curling up, and thus achieving the effect of filtering dust and other impurities.
[0013] Preferably, the weighing device includes a rectangular plate rotatably connected to the inner wall of the feeding frame. A weighing frame is fixedly connected to the upper top of the rectangular plate. A winding wheel is rotatably connected to the side of the feeding frame. A pulling rope is wound around the surface of the winding wheel. The other end of the pulling rope is fixedly connected to the upper top of the rectangular plate. A roller is rotatably connected to the side of the rectangular plate, and the roller is in close fit with the inner wall of the feeding frame.
[0014] The effects achieved by the above components are as follows: Under the action of the weighing frame, the medical raw materials can be accurately weighed, avoiding the phenomenon that the medicine cannot be used due to inaccurate weighing.
[0015] Preferably, a through groove is formed in the surface of the rectangular plate. A groove is formed inside the through groove. A spring rod is fixedly connected to the inner wall of the groove, and the other end of the spring rod is fixedly connected to the inner wall of the through groove.
[0016] The effects achieved by the above components are as follows: Under the action of the spring rod, when the rectangular plate rotates, the medicine presses on one side of the weighing frame, thereby opening the weighing frame and allowing the medicine to fall into the mixing tank through the through groove.
[0017] Preferably, a round bar is fixedly connected to the inner wall of the through groove, and the round bar is a rubber bar.
[0018] The effect achieved by the above components is that under the action of the round bar, when the spring rod resets the rectangular plate and the other side of the weighing frame, the phenomenon of rigid contact will not occur.
[0019] Preferably, a rotating rod is fixedly connected to the side surface of the wire winding wheel. One end of the rotating rod is provided with a clamping rod, the clamping rod is inserted into the side surface of the feeding frame, a first spring is sleeved on the surface of the clamping rod, and both ends of the first spring are fixedly connected to one end of the rotating rod and one end of the clamping rod respectively.
[0020] The effect achieved by the above components is that under the action of the first spring, the pulling rope can be fixed after being wound around the surface of the wire winding wheel, avoiding the phenomenon that the pulling rope loosens from the surface of the wire winding wheel. When weighing medicine is required, the rectangular plate is placed horizontally on the inner wall of the feeding frame, and the rectangular plate is fixed under the action of the pulling rope and the wire winding wheel. After the medicine is weighed, the clamping rod is pulled outwards to make the rectangular plate rotate. Then, under the action of the roller, it moves more smoothly. When it rotates to an appropriate angle, under the pressure of the medicine, the spring rod elongates, making the through groove larger, and the medicine falls out from the through groove. When all the medicine has fallen out, the wire winding wheel is rotated to make the pulling rope wind around the surface of the wire winding wheel. Under the action of the spring rod, the through groove contracts and becomes smaller. Then, under the action of the roller, it resets. During the reset process, under the action of the round bar, when the spring rod resets the rectangular plate and the other side of the weighing frame, the phenomenon of rigid contact will not occur. When the pulling rope is wound around the surface of the wire winding wheel, under the action of the first spring, the pulling rope can be fixed after being wound around the surface of the wire winding wheel, avoiding the phenomenon that the pulling rope loosens from the surface of the wire winding wheel, thus achieving the function of weighing.
[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.
[0022] In the present utility model, by providing a filtering device, when air needs to be introduced, activated carbon is loaded into the inside of the filter plate, and the filter plate is installed on one side of the retaining ring on the inner wall of the air inlet pipe. The threaded rod is rotated to make the filter screen move towards the inside of the air inlet pipe. Under the action of the staple, the filter plate can be fixed between the retaining ring and the filter screen, avoiding the phenomenon that the filter plate curls up together, and thus achieving the function of filtering dust and other impurities, thereby solving the problem that when cold air is introduced into the mixing tank, dust and other impurities will be brought into the mixing tank together.

[0028] Example 1, as Figures 1-4 shown, a mixer of raw materials for producing biological medical reagents includes a mixing tank 1. A feeding frame 4 is fixedly connected to the upper top of the mixing tank 1. A weighing device 3 is arranged inside the feeding frame 4. An air pump 6 is fixedly connected to the upper top of the mixing tank 1. The output end of the air pump 6 is fixedly connected to an air ring 7. The air ring 7 is fixedly connected to the upper top of the mixing tank 1. A motor 5 is fixedly connected to the upper top of the air ring 7. The output end of the motor 5 is fixedly connected to a stirring rod. A circular groove is formed inside the stirring rod, and a through groove is formed on the surface of the stirring rod. One end of the air pump 6 is fixedly connected to an intake pipe 8. A filtering device 2 is arranged inside the intake pipe 8. When it is necessary to mix medical raw materials, the medical raw materials are poured into the inside of the mixing tank 1 through the feeding frame 4 for uniform mixing. If cold air needs to be introduced into the medical raw materials, the air pump 6 is started, so that the gas enters into the inside of the air ring 7. Under the action of the circular groove and the through hole, it enters into the mixing tank 1 for cooling, and thus the function of mixing medical raw materials is completed.
[0029] Refer to Figure 2, the filtering device 2 includes a filter screen 27 disposed inside the air inlet pipe 8. Under the action of the filter screen 27, large particulate impurities in the air can be filtered out, so that impurities such as large particulate dust do not enter the inside of the mixing tank 1. When it is necessary to mix medical raw materials, the medical raw materials are poured into the inside of the mixing tank 1 through the feeding frame 4 for uniform mixing. If cold air needs to be introduced into the medical raw materials, the air pump 6 is started to make the gas enter the inside of the air ring 7. Under the action of the circular groove and the through hole, it enters the inside of the mixing tank 1 for cooling, and then the function of mixing medical raw materials is completed. A retaining ring 23 is fixedly connected to the inside of the air inlet pipe 8. One end of the retaining ring 23 is provided with a filter plate 24. A rectangular groove 21 is opened on the inner wall of the air inlet pipe 8. A threaded rod 22 is rotatably connected to the inner wall of the rectangular groove 21. The surface of the threaded rod 22 is threadedly connected with the filter screen 27. An activated carbon 25 is provided inside the filter plate 24. Under the action of the filter plate 24 and the activated carbon 25, small particulate dust is also blocked outside, so as to achieve the function of filtering impurities in the air. A nail 28 is fixedly connected to the side of the filter screen 27. The nail 28 is inserted into the inside of the filter plate 24. Under the action of the nail 28, the filter plate 24 will not curl up inside the air inlet pipe 8, avoiding the phenomenon of incomplete filtering caused by curling up. A fixing rod 26 is fixedly connected to the inside of the rectangular groove 21. The surface of the fixing rod 26 is slidably connected with the filter screen 27. Under the action of the fixing rod 26, the filter screen 27 will not rotate with the rotation of the threaded rod 22. When it is necessary to introduce air, the activated carbon 25 is loaded into the inside of the filter plate 24, and the filter plate 24 is installed on one side of the retaining ring 23 on the inner wall of the air inlet pipe 8. The threaded rod 22 is rotated to make the filter screen 27 move towards the inside of the air inlet pipe 8. Under the action of the nail 28, the filter plate 24 can be fixed between the retaining ring 23 and the filter screen 27, avoiding the phenomenon of the filter plate 24 curling up, and thus achieving the function of filtering dust and other impurities.
[0030] Refer to Figures 3-4, the weighing device 3 includes a rectangular plate 31 rotatably connected to the inner wall of the feeding frame 4. A weighing frame 32 is fixedly connected to the upper top of the rectangular plate 31. A wire winding wheel 34 is rotatably connected to the side of the feeding frame 4. A pulling rope is wound around the surface of the wire winding wheel 34, and the other end of the pulling rope is fixedly connected to the upper top of the rectangular plate 31. A roller 33 is rotatably connected to the side of the rectangular plate 31, and the roller 33 is in close contact with the inner wall of the feeding frame 4. Under the action of the weighing frame 32, the medical raw materials can be accurately weighed, avoiding the phenomenon that the medicine cannot be used due to inaccurate weighing. A through groove is formed on the surface of the rectangular plate 31, and a groove 38 is formed inside the through groove. A spring rod 39 is fixedly connected to the inner wall of the groove 38, and the other end of the spring rod 39 is fixedly connected to the inner wall of the through groove. Under the action of the spring rod 39, when the rectangular plate 31 rotates, the medicine presses on one side of the weighing frame 32, thereby opening the weighing frame 32 and allowing the medicine to fall into the mixing tank 1 from inside the through groove. A round bar 37 is fixedly connected to the inner wall of the through groove. The round bar 37 is a rubber strip. Under the action of the round bar 37, when the spring rod 39 resets the other side of the rectangular plate 31 and the weighing frame 32, there will be no rigid contact phenomenon. A rotating rod is fixedly connected to the side of the wire winding wheel 34. One end of the rotating rod is inserted with a clamping rod 35. The clamping rod 35 is inserted into the side of the feeding frame 4. A first spring 36 is sleeved on the surface of the clamping rod 35. The two ends of the first spring 36 are respectively fixedly connected to one end of the rotating rod and one end of the clamping rod 35. Under the action of the first spring 36, the pulling rope can be fixed after being wound around the surface of the wire winding wheel 34, avoiding the phenomenon that the pulling rope comes off the surface of the wire winding wheel 34. When weighing medicine is required, the rectangular plate 31 is placed horizontally on the inner wall of the feeding frame 4, and the rectangular plate 31 is fixed under the action of the pulling rope and the wire winding wheel 34. After the medicine is weighed, the clamping rod 35 is pulled outwards, causing the rectangular plate 31 to rotate. Then, under the action of the roller 33, it moves more smoothly. When it rotates to an appropriate angle, under the pressure of the medicine, the spring rod 39 elongates, making the through groove larger, and the medicine falls out of the through groove. When all the medicine has fallen, the wire winding wheel 34 is rotated to wind the pulling rope around the surface of the wire winding wheel 34. Under the action of the spring rod 39, the through groove contracts and becomes smaller. Then, under the action of the roller 33, it resets. During the reset process, under the action of the round bar 37, when the spring rod 39 resets the other side of the rectangular plate 31 and the weighing frame 32, there will be no rigid contact phenomenon. When the pulling rope is wound around the surface of the wire winding wheel 34, under the action of the first spring 36, the pulling rope can be fixed after being wound around the surface of the wire winding wheel 34, avoiding the phenomenon that the pulling rope comes off the surface of the wire winding wheel 34, thus achieving the weighing function.
[0031] Working principle: When the raw material mixer for biopharmaceutical reagents is needed and the medical raw materials need to be mixed, the medical raw materials are poured into the interior of the mixing tank 1 through the feeding frame 4 for uniform mixing. If cold air needs to be introduced into the medical raw materials, start the air pump 6 so that the gas enters the interior of the air ring 7. Under the action of the circular groove and the through hole, it enters the interior of the mixing tank 1 for cooling, and then the mixing of the medical raw materials is completed. When air needs to be introduced, the activated carbon 25 is loaded into the interior of the filter plate 24, and the filter plate 24 is installed on one side of the retaining ring 23 on the inner wall of the air inlet pipe 8. Turn the threaded rod 22 so that the filter screen 27 moves into the interior of the air inlet pipe 8. Under the action of the staple 28, the filter plate 24 can be fixed between the retaining ring 23 and the filter screen 27, avoiding the phenomenon that the filter plate 24 curls up together, and thus achieving the function of filtering dust and other impurities. When weighing the medicine, the rectangular plate 31 is placed horizontally on the inner wall of the feeding frame 4 and fixed by the pull rope and the winding wheel 34. After the medicine is weighed, pull out the positioning rod 35 outward so that the rectangular plate 31 rotates, and then under the action of the roller 33, it moves more smoothly. When it rotates to the appropriate angle, under the pressure of the medicine, the spring rod 39 elongates, making the through groove larger, and the medicine falls out from the through groove. When all the medicine has fallen out, rotate the winding wheel 34 so that the pull rope winds around the surface of the winding wheel 34. Under the action of the spring rod 39, the through groove contracts and becomes smaller, and then under the action of the roller 33, it returns to its original position. During the reset process, under the action of the round bar 37, the spring rod 39 will not cause a rigid contact phenomenon when resetting the other side of the rectangular plate 31 and the weighing frame 32. When the pull rope winds around the surface of the winding wheel 34, under the action of the first spring 36, the pull rope can be fixed after winding around the surface of the winding wheel 34, avoiding the phenomenon that the pull rope loosens from the surface of the winding wheel 34, thus achieving the function of weighing.
