Description

Technical Field

[0001] This utility model relates to the field of cephalosporin screening technology, specifically a screening device for cephalosporin production. Background Technology

[0002] Cephalosporins are a general term for cephalosporin antibiotics. Cephalosporins are a class of antibiotics obtained by semi-synthetically modifying the side chains of natural cephalosporin C obtained from the culture of Cephalosporin. There are about 30 commonly used cephalosporins, which are divided into first, second, third, fourth and fifth generations according to their generation and antibacterial properties. Cephalosporin antibiotics occupy a large share of the antibiotic market, and their related intermediates also show considerable market potential. The best-selling cephalosporin antibiotics include ceftriaxone sodium, cefazolin sodium, cefotaxime, ceftriaxone, cefoperazone and cefuroxime (ester).

[0003] The current device uses a screening mesh to screen cephalosporins during the screening process. However, impurities can easily get mixed into the cephalosporins. At the same time, the driving device is relatively weak, which can cause cephalosporins to accumulate on top of the screening mesh.

[0004] In view of this, we propose a screening device for cephalosporin production. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a screening device for cephalosporin production.

[0006] The technical solution of this utility model is:

[0007] A screening device for cephalosporin production includes a main body for cephalosporin production, a screening component detachably installed inside the main body, and a separation component fixedly installed inside the main body. The separation component includes a first contraction spring, a first connecting plate, a telescopic cylinder, a telescopic rod, a second connecting plate, and a separation seat. The first contraction spring is fixedly installed below the end of the separation component, the first connecting plate is fixedly installed inside the first contraction spring, the separation seat is fixedly installed at the end of the first contraction spring, and the second connecting plate is fixedly installed at the other end of the first connecting plate.

[0008] As a preferred technical solution, a telescopic rod is installed above the connecting plate 2, the input end of the telescopic rod is slidably connected to the output end of the telescopic cylinder, a separation plate is slidably connected inside the separation seat, and the side of the separation seat is slidably connected to the inner side of the main body of the cephalosporin production screening device.

[0009] As a preferred technical solution, an adjusting shaft is slidably connected to the inner side of the screening assembly, a screening plate is fixedly installed at the end of the adjusting shaft, a second contraction spring is fixedly connected to both the front and rear ends of the screening plate, a mounting base is fixedly connected to the other end face of the second contraction spring, and a connecting base is fixedly installed at the rear end of the screening plate.

[0010] As a preferred technical solution, a movable frame one is fixedly installed on the side of the connecting seat, a mounting seat is slidably connected to the side of the movable frame one, and a movable frame two is rotatably connected to the other end of the movable frame one.

[0011] As a preferred technical solution, the side of the movable frame two is rotatably connected to a limiting seat, the rear end of the movable frame two is fixedly installed with a drive shaft, the side of the drive shaft is meshed with a drive track, and the other end of the drive track is fixedly installed at the output end of the drive motor.

[0012] As a preferred technical solution, a storage bin is fixedly installed below the main body of the cephalosporin production screening device, and a drive chamber is opened on the right side of the storage bin.

[0013] As a preferred technical solution, a support column is fixedly installed below the main body of the cephalosporin production screening device.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In the sieving process of cephalosporins, the cephalosporins are first placed into the main body of the cephalosporin production sieving device. The cephalosporins fall above the separation plate. The telescopic cylinder is activated to extend and retract the telescopic rod, which drives the connecting plate 2 at its end. The connecting plate 1 drives the connecting plate 2 at the other end, causing the fixed contraction spring 1 to extend and retract in conjunction with the connecting plate 1. This increases the vibration caused by the extension and retraction, causing the separation seat fixed at the end to vibrate continuously. This causes the separation plate that slides in inside to vibrate, allowing the cephalosporins above to proceed to the next sieving step. At the same time, the separation plate can slide out from inside the separation seat to process the different impurities separated above.

[0016] 2. In this invention, when the cephalosporin enters the sieve plate, the drive motor starts and controls its output end to drive the transmission belt to engage. The transmission belt drives the transmission shaft at the other end, which causes the movable frame 1 on its side to rotate. This drives the movable frame 2 to move forward and backward, pushing the sieve plate forward to squeeze the contraction spring 2 on the side, and then moving it backward to squeeze the contraction spring 2 again. This performs secondary sieving of the cephalosporin above the sieve plate. The sieving cephalosporin enters the sieve storage bin, preventing impurities from mixing in. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution:

[0026] A screening device for cephalosporin production includes a screening device body 1 for cephalosporin production. A screening component 3 is detachably installed inside the screening device body 1. A separation component 2 is fixedly installed inside the screening device body 1. The separation component 2 includes a first contraction spring 21, a first connecting plate 22, a telescopic cylinder 23, a telescopic rod 24, a second connecting plate 25, and a separation seat 26. The first contraction spring 21 is fixedly installed below the end of the separation component 2. The first connecting plate 22 is fixedly installed inside the first contraction spring 21. The separation seat 26 is fixedly installed at the end of the first contraction spring 21. The second connecting plate 25 is fixedly installed at the other end of the first connecting plate 22. The telescopic rod 24 is installed above the second connecting plate 25. The input end of the telescopic rod 24 is slidably connected to the output end of the telescopic cylinder 23. A separation plate 27 is slidably connected inside the separation seat 26. The side of the separation seat 26 is slidably connected to the inside of the screening device body 1 for cephalosporin production.

[0027] It should be added that, in the cephalosporin screening process, the cephalosporins are first placed into the main body 1 of the cephalosporin production screening device. The cephalosporins fall above the separation plate 27. The telescopic cylinder 23 is activated to extend and retract the telescopic rod 24, causing the connecting plate 25 at its end to be driven. The connecting plate 22 drives the connecting plate 25 at the other end, causing the fixed contraction spring 21 to extend and retract in conjunction with the connecting plate 22, increasing the vibration caused by the extension and retraction. This causes the separation seat 26 fixed at the end to vibrate continuously, driving the internally sliding separation plate 27 to vibrate, allowing the cephalosporins above to proceed to the next screening step. At the same time, the separation plate 27 can slide out from inside the separation seat 26 to process the different impurities separated above.

[0028] In a preferred embodiment, an adjusting shaft 31 is slidably connected to the inner side of the screening assembly 3. A screening plate 32 is fixedly installed at the end of the adjusting shaft 31. A second contraction spring 33 is fixedly connected to both the front and rear ends of the screening plate 32. A mounting seat 36 is fixedly connected to the other end face of the second contraction spring 33. A connecting seat 34 is fixedly installed at the rear end of the screening plate 32. A movable frame 35 is fixedly installed on the side of the connecting seat 34. The mounting seat 36 is slidably connected to the side of the movable frame 35. A second movable frame 37 is rotatably connected to the other end of the movable frame 35. A limit seat 38 is rotatably connected to the side of the movable frame 37. A transmission shaft 39 is fixedly installed at the rear end of the movable frame 37. A transmission track 311 is meshed with the side of the transmission shaft 39. The other end of the transmission track 311 is fixedly installed at the output end of the drive motor 310.

[0029] It is worth noting that when the cephalosporin enters above the screening plate 32, the drive motor 310 is started, and its output end drives the transmission track 311 to engage and drive the transmission shaft 39 at the other end of the transmission track 311. The transmission shaft 39 causes the movable frame 35 on its side to rotate, which drives the movable frame 37 to move forward and backward. This causes the movable frame 37 to push the screening plate 32 forward and squeeze the contraction spring 33 on the side, and then move backward and squeeze the contraction spring 33 again, thus performing secondary screening of the cephalosporin above the screening plate 32. The cephalosporin that has passed through screening enters the screening storage bin 13, preventing impurities from mixing in.

[0030] As a preferred embodiment, a storage bin 13 is fixedly installed below the main body 1 of the cephalosporin production screening device, a drive chamber 12 is opened on the right side of the storage bin 13, and a support column 11 is fixedly installed below the main body 1 of the cephalosporin production screening device.

[0031] In actual use, the screening component 3 is driven by the drive chamber 12, and the cephalosporins that have been screened are stored in the storage chamber 13.

[0032] In the use of this utility model's screening device for cephalosporin production, the cephalosporins are first placed into the main body 1 of the screening device during the screening operation. The cephalosporins fall above the separation plate 27. The telescopic cylinder 23 is activated to extend and retract the telescopic rod 24, driving the connecting plate 25 at its end. The connecting plate 22 drives the other connecting plate 25, causing the fixed contraction spring 21 to extend and retract in conjunction with the connecting plate 22. This increases the vibration caused by the extension and retraction, resulting in continuous vibration of the fixed separation seat 26 at its end. This vibration drives the internally sliding separation plate 27 to vibrate, allowing the cephalosporins to proceed to the next screening step. The separating plate 27 can slide out from inside the separating seat 26 to process the different impurities separated above. When the cephalosporin enters above the screening plate 32, the drive motor 310 is started, and its output end drives the transmission track 311 to engage and drive the transmission shaft 39 at the other end of the transmission track 311. The transmission shaft 39 causes the movable frame 35 on its side to rotate, driving the movable frame 37 to move forward and backward. The movable frame 37 pushes the screening plate 32 forward to squeeze the contraction spring 33 on the side and then moves backward to squeeze the contraction spring 33, thus performing secondary screening of the cephalosporin above the screening plate 32. The screened cephalosporin enters the screening storage bin 13 to prevent impurities from mixing in.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
