Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical particle screening, in particular to a pharmaceutical particle screening device. Background Art

[0002] Since the production process of drugs often produces particles of different diameters or particles agglomerate, it is particularly important to screen the drug particles. Screening by size is the lowest cost, most time-saving and labor-saving method.

[0003] At present, the traditional screening method only has the function of screening. The agglomeration state of some drug particles during processing cannot be effectively solved, so that the drug particles are still largely impure after screening, which in turn results in increased workload and low screening quality. In addition, after the sieve plate is screened, drug particles will remain on the surface of the sieve plate, which requires cleaning later, thereby increasing the cleaning time.

[0004] Therefore, we propose a drug particle screening device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a drug particle screening device to solve the problems raised in the above background technology that drug particles agglomerate, resulting in low screening quality and retention on the sieve plate surface.

The connecting rod is connected to the rotating rod through a cross protrusion, and a connecting block is provided on the surface of the rotating rod. A second scraper is installed at the end of the connecting block. The periphery of the top of the rotating rod is connected to a screen plate.

[0008] A discharge port is provided on the right side of the device body.

[0009] Preferably, notches adapted to the ends of the pull rod are provided on both sides of the interior of the device body, and the pull rod forms a sliding structure with the interior of the device body through the notches.

[0010] Preferably, a cross groove adapted to the cross protrusion is provided on the top of the connecting rod, and the connecting rod is movably connected to the cross protrusion via the cross groove.

[0011] Preferably, the sieve plate and the bottom of the device body are inclined.

[0012] Preferably, the first scraper and the second scraper are parallel to the screen plate and the bottom of the device body.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the drug particle screening device,

[0014] (1) When the sieve plate needs to be replaced or repaired, the pull block is pulled to move the first stopper on the pull rod surface toward the second stopper, thereby compressing the spring between the first stopper and the second stopper, and then the pull rod slides in the slot, thereby releasing the fixation of the sieve plate and allowing the sieve plate to be taken out of the device body, thereby reducing maintenance time.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 The utility model provides a technical solution: a drug particle screening device, comprising a device body 1, a feed port 2 is opened on the top of the device body 1, a pull rod 3 is installed inside the top of the device body 1, and a first stopper 4 is passed through the surface of the pull rod 3, and a spring 5 is connected to one side of the first stopper 4, and a second stopper 6 is installed on the end of the spring 5 away from the first stopper 4, a pull block 19 is installed on the end of the pull rod 3 away from the inner wall of the device body 1, a connecting plate 9 is connected to the bottom of the second stopper 6, and fixed blocks 7 are installed at both ends of the bottom of the connecting plate 9, and the bottom of the fixed block 7 is embedded in the limit block 8, and a first scraper 15 is provided on the right side of the bottom of the connecting plate 9;

[0026] The motor 10 is installed at the bottom of the device body 1, and the output end of the motor 10 is connected to the connecting rod 11, which is connected to the rotating rod 12 through a cross protrusion 18. A connecting block 13 is provided on the surface of the rotating rod 12, and a second scraper 14 is installed at the end of the connecting block 13. The outer periphery of the top of the rotating rod 12 is connected to a sieve plate 17;

[0027] A discharge port 16 is provided on the right side of the device body 1 .

[0028] Slots corresponding to the ends of the pull rod 3 are provided on both sides of the inside of the device body 1, and the pull rod 3 forms a sliding structure with the inside of the device body 1 through the slots. When the sieve plate 17 needs to be replaced or repaired, the pull block 19 is pulled to move the first stop block 4 on the surface of the pull rod 3 toward the second stop block 6, so that the spring 5 between the first stop block 4 and the second stop block 6 is compressed, and then the pull rod 3 slides in the slot, thereby releasing the fixation of the sieve plate 17 and allowing the sieve plate 17 to be taken out of the device body 1, thereby reducing maintenance time.

[0029] A cross groove adapted to the cross protrusion 18 is provided on the top of the connecting rod 11. The connecting rod 11 is movably connected to the cross protrusion 18 through the cross groove. When the screen plate 17 is replaced and then installed, the cross protrusion 18 can continue to be effectively connected, and the connection will not affect the rotation of the connecting rod 11 and the rotating rod 12.

[0030] The sieve plate 17 and the bottom of the device body 1 are inclined. By starting the motor 10, the motor 10 is put into operation, and the motor 10 drives the connecting rod 11 to rotate counterclockwise. The rotation of the connecting rod 11 drives the rotating rod 12 to rotate, thereby realizing the rotation of the sieve plate 17 connected to the periphery of the rotating rod 12. The rotation of the sieve plate 17 generates centrifugal force that can throw the drug particles into the device body 1, so that the adhered drug particles are broken by the inner wall of the device body 1, and then the drug particles are screened downward through the sieve plate 17 and enter the bottom of the device body 1. Such a structure can improve the accuracy of drug particle screening, thereby reducing the doping of drug particles after screening and improving the screening quality.

[0031] The first scraper 15 and the second scraper 14 are parallel to the sieve plate 17 and the bottom of the device body 1. After the sieve plate 17 screens the drug particles, the drug particles are scraped off by the first scraper 15, so that the screened drug particles can move to the discharge port 16 to the maximum extent and be discharged, thereby reducing the residue on the surface of the sieve plate 17 and inside the device body 1, thereby reducing the cleaning time inside the device body 1.

[0032] Working principle: When using the drug particle screening device, first, start the motor 10 to make the motor 10 work, the motor 10 drives the connecting rod 11 to rotate counterclockwise, and the rotation of the connecting rod 11 drives the rotating rod 12 to rotate, thereby realizing the rotation of the sieve plate 17 connected to the outer periphery of the rotating rod 12;

[0033] Next, drug particles are added to the device body 1 through the feed port 2, so that the drug particles fall onto the surface of the sieve plate 17 through the feed port 2 for screening. The rotation of the sieve plate 17 generates centrifugal force that can throw the drug particles onto the inner wall of the device body 1, so that the drug particles that stick together are broken by the inner wall of the device body 1. Then, the drug particles are screened downward through the sieve plate 17 and enter the bottom of the device body 1. This structure can improve the accuracy of drug particle screening, thereby reducing the doping of drug particles after screening and improving the screening quality.

[0034] Afterwards, after the sieve plate 17 has screened the drug particles, since the sieve plate 17 is in a frustum shape, when the through groove on the side wall of the sieve plate 17 corresponds to the position of the discharge port 16 on the upper right side of the device main body 1, the large drug particles will flow to the discharge port 16 on the upper right side of the device main body 1, and then the first scraper 15 arranged on the right side of the bottom of the connecting plate 9 will scrape the drug particles, so that the drug particles retained on the surface of the sieve plate 17 can move to the discharge port 16 to the maximum extent, so as to be discharged, thereby reducing the retention on the surface of the sieve plate 17, and the drug particles flowing to the bottom of the device main body 1 are scraped by the second scraper 14 at the end of the connecting block 13 so that the drug particles can flow to the discharge port 16 on the lower left side of the device main body 1 and be discharged. Such a structure can effectively reduce the retention of drug particles on the surface of the sieve plate 17 and inside the device main body 1, thereby reducing the cleaning time inside the device main body 1;

[0035] Finally, when the sieve plate 17 needs to be replaced or repaired, first remove the bolts on the left side of the device body 1 to release the fixation, then use the rotating shaft on the right side of the device body 1 to flip the top of the device body 1 so that the internal parts are exposed, and then pull the pull block 19 to move the first stopper 4 on the surface of the pull rod 3 toward the second stopper 6, so that the spring 5 between the first stopper 4 and the second stopper 6 is compressed, and then the pull rod 3 slides in the slot, thereby releasing the fixation of the connecting plate 9, and then releasing the fixation of the sieve plate 17. , and then pull the connecting plate 9 upward to make the fixing block 7 slide out of the limit block 8, so that the rotating rod 12 at the bottom of the sieve plate 17 can be taken out from the device body 1, which reduces the maintenance time, and a cross protrusion 18 is provided at the bottom of the rotating rod 12. When the sieve plate 17 is taken out and replaced, the cross protrusion 18 can continue to effectively connect the top of the connecting rod 11, and the connection will not affect the rotation of the connecting rod 11 and the rotating rod 12.
