On the upper surface of the connecting plate A, there is a U-shaped clamping plate, and on the U-shaped clamping plate, there are a coarse filter plate and a fine filter plate, and the coarse filter plate is located above the fine filter plate. Through the setting of a series of structures, the utility model can effectively remove dust impurities in the crude heparin sodium, and at the same time, drying and sterilization treatments can be carried out to improve the quality of the crude heparin sodium.

[0003] However, there are some problems in the prior art: The existing screening device for heparin sodium production cannot continuously screen the crude heparin sodium. After screening a batch, it is necessary to take out the screened heparin sodium and then put in new crude heparin sodium for screening, resulting in low screening efficiency. Therefore, we propose a screening device for heparin sodium production. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a screening device for heparin sodium production, which automatically feeds through a feeding plate and a collecting hopper and automatically discharges through an inclined sieve plate, so as to automatically complete the screening of crude heparin sodium and improve the screening efficiency.

[0005] The present utility model is realized as follows. A screening device for heparin sodium production includes a housing. A cavity is provided inside the housing.

[0010] Optionally, the driving component includes a motor. The motor is fixedly connected to the upper end of the housing. A rotating disc is fixedly connected to the movable end of the motor. The rotating disc is rotatably connected to a connecting rod. The connecting rod is rotatably connected to one end of the first support rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model automatically adds the crude heparin sodium to the screening device for heparin sodium production through the feeding plate and the aggregate hopper. Coupled with the inclined sieve plate, the crude heparin sodium automatically moves downward into the aggregate box during the screening process, thus completing automatic discharging. The two are combined to automatically complete the screening of the crude heparin sodium, improving the screening efficiency and reducing the workload of the staff.

[0013] The present utility model is also provided with a driving component, which can drive the rotating disc to rotate through the motor, so that the connecting rod continuously moves.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] As Figures 1 to 5 shown, a screening device for heparin sodium production provided by an embodiment of the present invention includes a housing 1. The housing 1 is rectangular and made of stainless steel material. Its main function is to support the entire device and protect the components inside it. The housing 1 can also prevent the floating dust generated during the screening process from flying around, resulting in a poor external environment and affecting the work of the staff.

[0023] A cavity is provided inside the outer shell 1. A sieve plate 2 is movably connected inside the cavity. A support plate 8 is fixedly connected to the inner wall of the outer shell 1. A spring 9 is fixedly connected to the upper end of the support plate 8, and the spring 9 is fixedly connected to the bottom end of the sieve plate 2. One end of the sieve plate 2 is fixedly connected to a fixed frame 10, and a vibrator 11 is fixedly connected to the bottom end of the fixed frame 10.

[0024] After the vibrator 11 is started, the sieve plate 2 will vibrate. Under the action of the spring 9, the sieve plate 2 will continue to vibrate, so that impurities, dust and small particle crude heparin sodium on the sieve plate 2 are screened out from the sieve plate 2 into the slag collection box 301 for collection, while the remaining crude heparin sodium will move along the inclined sieve plate 2 under the action of vibration and finally enter the aggregate box 4 for collection.

[0025] A slag collection component 3 is movably connected inside the cavity of the outer shell 1. The slag collection component 3 includes a slag collection box 301, and the slag collection box 301 is movably connected inside the cavity of the outer shell 1. One end of the slag collection box 301 is fixedly connected to a handle 302.

[0026] The slag collection box 301 is arranged below the sieve plate 2. Impurities, dust and small particle crude heparin sodium on the sieve plate 2 are screened out from the sieve plate 2 into the slag collection box 301 for collection. After the collection is completed, the slag collection box 301 can be taken out of the screening device through the handle 302 to further process the collected impurities, dust and small particle crude heparin sodium.

[0027] An outlet is provided on one side of the outer shell 1. The sieve plate 2 passes through the outlet. An aggregate box 4 is fixedly connected to the outer wall of the outer shell 1. The aggregate box 4 is arranged below the outlet, and the aggregate box 4 will collect the crude heparin sodium screened by the sieve plate 2 for subsequent reprocessing.

[0028] A feeding plate 5 is movably connected to the inner wall of the outer shell 1. An inlet is provided at the upper end of the outer shell 1. The feeding plate 5 is arranged inside the inlet. A first support rod 12 is movably connected to the inner wall of the cavity of the outer shell 1. A second support rod 13 is movably connected to the upper end of the outer shell 1. The first support rod 12 and the second support rod 13 are respectively fixedly connected to both ends of the feeding plate 5, and the feeding plate 5 can slide horizontally under the action of the first support rod 12 and the second support rod 13.

[0029] A driving component 6 is fixedly connected to the upper end of the outer shell 1. The driving component 6 is used to drive the feeding plate 5 to move. The driving component 6 includes a motor 601, the motor 601 is fixedly connected to the upper end of the outer shell 1, a rotating disc 602 is fixedly connected to the movable end of the motor 601, and a connecting rod 603 is rotatably connected to the rotating disc 602, and the connecting rod 603 is rotatably connected to one end of the first support rod 12.

[0030] After the motor 601 rotates, it drives the turntable 602 to rotate, causing the connecting rod 603 rotatably connected to the turntable 602 to move cyclically, so that the first support rod 12 slides back and forth on the housing 1, and then causes the feeding plate 5 to shake back and forth, thus enabling the crude heparin sodium to enter the screening area evenly and stably.

[0031] A collecting hopper 7 is fixedly connected to the upper end of the housing 1. The collecting hopper 7 is used to store the crude heparin sodium that has not been screened, and continuously supplies the crude heparin sodium to the screening device.

[0032] The working principle of the present utility model is as follows:

[0033] The present utility model automatically adds the crude heparin sodium to the screening device for heparin sodium production through the feeding plate 5 and the collecting hopper 7. Coupled with the inclined sieve plate 2, the crude heparin sodium automatically moves downward into the collecting box 4 during the screening process, thereby completing automatic discharging. The combination of the two automatically completes the screening of the crude heparin sodium, improves the screening efficiency, and reduces the workload of the staff.

[0034] The present utility model is also provided with a driving assembly 6, which can drive the turntable 602 to rotate through the motor 601, so that the connecting rod 603 continuously moves. The connecting rod 603 then drives the first support rod 12 to shake, and further causes the feeding plate 5 to shake continuously, ensuring that the crude heparin sodium enters the screening area evenly and stably, and avoiding incomplete screening caused by too much crude heparin sodium entering the screening area at the same time.

[0035] The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
