[0002] Pharmaceutical intermediates are actually chemical raw materials or products used in the process of drug synthesis. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis.

[0003] To enhance the efficacy of a drug, pharmaceutical intermediates are often concentrated again. However, if the product is directly reviewed after the pharmaceutical intermediates have been concentrated, the concentrated pharmaceutical intermediates may contain lumps and particles, which may affect the taste of the product during production and may even have a certain impact on the efficacy of the drug. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing pharmaceutical intermediates that are directly examined after concentration. The concentrated pharmaceutical products may contain lumps and particles, which may affect the taste of the product during production and even seriously affect its medicinal properties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical intermediate concentration and filtration device, comprising a filter tank, a collection chamber fixedly connected to the bottom end of the filter tank, a support base fixedly connected to the outside of the collection chamber, a drive motor disposed directly below the collection chamber and fixedly connected inside the support base, a connecting seat fixedly connected to the outside of the top end of the filter tank, and a pressure booster fixedly connected to the top end of the connecting seat, the output end of the pressure booster extending to the top of the filter tank, a connecting cover fixedly connected to the bottom end of the pressure booster, and several conveying pipes fixedly connected to the outside of the connecting cover, the bottom end of the connecting cover penetrating the top end of the filter tank and extending inside it to be movably connected to a discharge mechanism, and the bottom end of the discharge mechanism fixedly connected to a filter slag discharge mechanism.

[0006] As a further technical solution of this utility model, the feeding mechanism includes a receiving bucket, a distributing block, a discharge pipe, a connecting shaft, and a processing platform. The distributing block is a cone-shaped object fixedly connected to the bottom of the receiving bucket. The discharge pipe has several parts arranged in a ring array and fixedly connected to the outside of the receiving bucket. The discharge pipe is interconnected with the inside of the receiving bucket. The lower part of the discharge pipe has several discharge holes. The connecting shaft is fixedly connected to the center of the bottom of the receiving bucket, and the processing platform is movably connected to the bottom of the connecting shaft through a bearing.

[0007] As a further technical solution of this utility model, the top of the receiving barrel is movably connected to the bottom of the connecting cover through a bearing, and the processing platform is configured as a filter screen.

[0008] As a further technical solution of this utility model, a groove is provided on the top edge of the processing platform. Two sets of pulleys are slidably connected inside the groove. One set of symmetrical pulleys is fixedly connected to scraper blades on opposite sides, and the other end of the scraper blades is fixedly connected to the outside of the connecting shaft. The other set of symmetrical pulleys is rotatably connected to pressure rollers on opposite sides, and the other end of the pressure rollers is movably connected to the outside of the connecting shaft through a rotating shaft.

[0009] As a further technical solution of this utility model, the filtration and slag discharge mechanism includes a main shaft, a filter cover, a slag discharge trough, a drive ring, and push bars. The filter cover is fixedly connected to the top of the main shaft, the slag discharge trough is annular and fixedly connected to the edge of the filter cover, the drive ring is located directly below the filter cover, and the push bars are symmetrically fixedly connected to the outside of the drive ring.

[0010] As a further technical solution of this utility model, the top end of the main shaft is fixedly connected to the bottom end of the connecting shaft, and the bottom end of the main shaft passes through the collection bin and is fixedly connected to the output end of the drive motor. The bottom end of the collection bin is connected to a discharge pipe.

[0011] As a further technical solution of this utility model, the bottom end of the push bar is adapted to the inner bottom end of the collection chamber, and the push bar is in close contact with the inner bottom end of the collection chamber.

[0012] Compared with existing technologies, this pharmaceutical intermediate concentration and filtration equipment has the following advantages:

[0013] 1. This utility model, through its feeding mechanism, allows concentrated pharmaceutical intermediates to fall into the receiving tank and then flow along the distribution block into the discharge pipe. At this time, the pressurizer is activated to pressurize the inside of the distribution tank. Simultaneously, the discharge pipe is driven to rotate by the receiving tank, and the pharmaceutical intermediates, under pressure, fall evenly from the discharge hole into the processing platform. The rotation of the connecting shaft also drives the pressure roller and scraper to rotate. The pressure roller further crushes the pharmaceutical intermediates remaining on the surface of the processing platform, and the scraper scoops up and spreads the crushed pharmaceutical intermediates. While the pressure roller and scraper are working, the end away from the connecting shaft drives the pulley to roll in the chute, which is beneficial for the reprocessing of concentrated pharmaceutical intermediates, reducing the content of lumps and particles, and reducing raw material consumption.

[0014] 2. This utility model, through its filter and slag discharge mechanism, drives the main shaft to rotate the connecting shaft and the receiving bucket, while simultaneously rotating the filter cover and the drive ring. At this time, the granular pharmaceutical intermediates are slowly rotated along the filter cover and thrown into the slag discharge trough for centralized processing. Qualified pharmaceutical intermediates fall into the bottom of the collection bin through the filter cover. At this time, the push bar agitates to prevent the pharmaceutical intermediates from clumping and pushes them towards the discharge pipe for transport to other equipment for concentration. This facilitates further concentration and screening of the pharmaceutical intermediates, improves the uniformity of the product, and prevents clumping during transport, which would affect product quality.

Detailed Implementation

[0020] 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.

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a pharmaceutical intermediate concentration and filtration device, including a filter tank 1, a collection chamber 2 fixedly connected to the bottom end of the filter tank 1, a support base 3 fixedly connected to the outside of the collection chamber 2, a drive motor 4 arranged directly below the collection chamber 2 and fixedly connected inside the support base 3, a connecting seat 5 fixedly connected to the outside of the top end of the filter tank 1, and a pressure booster 6 fixedly connected to the top end of the connecting seat 5, the output end of the pressure booster 6 extending to the top of the filter tank 1, a connecting cover 7 fixedly connected to the bottom end of the pressure booster 6, and several conveying pipes 8 fixedly connected to the outside of the connecting cover 7, the bottom end of the connecting cover 7 penetrating through the top end of the filter tank 1 and extending inside it is movably connected to a discharge mechanism 9, and the bottom end of the discharge mechanism 9 is fixedly connected to a filter slag discharge mechanism 10.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the feeding mechanism 9 includes a receiving bin 901, a distributing block 902, a discharge pipe 903, a connecting shaft 904, and a processing platform 905. The distributing block 902 is conical and fixedly connected to the bottom of the receiving bin 901. The discharge pipe 903 has several sections arranged in a ring array and fixedly connected to the outside of the receiving bin 901, and the discharge pipe 903 is interconnected with the inside of the receiving bin 901. The lower part of each discharge pipe 903 has several discharge holes 11. The connecting shaft 904 is fixedly connected to the center of the bottom of the receiving bin 901, and the processing platform 905 is movably connected to the connecting shaft 904 via bearings. At the bottom, the top of the receiving bucket 901 is movably connected to the bottom of the connecting cover 7 via a bearing. The processing platform 905 is set as a filter screen. A groove 12 is opened on the top edge of the processing platform 905. Two sets of pulleys 13 are slidably connected in the groove 12. One set of symmetrical pulleys 13 is fixedly connected to the opposite sides of each other, and the other end of the scraper 14 is fixedly connected to the outside of the connecting shaft 904. The other set of symmetrical pulleys 13 is rotatably connected to the opposite sides of each other, and the other end of the pressure roller 15 is movably connected to the outside of the connecting shaft 904 via a rotating shaft.

[0023] After concentration, the pharmaceutical intermediates fall into the receiving tank 901 and then flow into the discharge pipe 903 along the distribution block 902. At this time, the pressurizer 6 is activated to pressurize the inside of the distribution tank. As a result, the discharge pipe 903 is driven to rotate by the receiving tank 901, and the pharmaceutical intermediates are pressured and fall evenly from the discharge hole into the processing platform 905. The connecting shaft 904 rotates, which in turn drives the pressure roller 15 and the scraper 14 to rotate. Then, the pressure roller 15 crushes the pharmaceutical intermediates remaining on the surface of the processing platform 905 again, and the scraper 14 scoops up and spreads the crushed pharmaceutical intermediates. While the pressure roller 15 and the scraper 14 are working, the end away from the connecting shaft 904 drives the pulley 13 to roll in the chute 12, which is beneficial for the reprocessing of the concentrated pharmaceutical intermediates, reducing the content of lumps and particles, and reducing raw material consumption.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the filtration and slag discharge mechanism 10 includes a main shaft 1001, a filter cover 1002, a slag discharge trough 1003, a drive ring 1004, and a pusher bar 1005. The filter cover 1002 is fixedly connected to the top of the main shaft 1001. The slag discharge trough 1003 is annular and fixedly connected to the edge of the filter cover 1002. The drive ring 1004 is located directly below the filter cover 1002, and the pusher bar 1005 is symmetrically fixedly connected to the outside of the drive ring 1004. The top of the main shaft 1001 is fixedly connected to the bottom of the connecting shaft 904, and the bottom of the main shaft 1001 passes through the collection chamber 2 and is fixedly connected to the output end of the drive motor 4. The bottom of the collection chamber 2 is connected to the discharge pipe 16. The bottom of the pusher bar 1005 is adapted to the bottom of the collection chamber 2, and the pusher bar 1005 is in close contact with the bottom of the collection chamber 2.

[0025] The main shaft 1001 drives the connecting shaft 904 and the receiving tank 901 to rotate the filter cover 1002 and the drive ring 1004. At this time, the granular pharmaceutical intermediates are slowly rotated along the filter cover 1002 and thrown into the slag discharge tank 1003 to wait for centralized processing. The qualified pharmaceutical intermediates fall into the bottom of the collection bin 2 after being filtered by the filter cover 1002. At this time, the pusher bar 1005 stirs to prevent the pharmaceutical intermediates from clumping and pushes them to the discharge pipe 16 for conveying to other equipment for concentration. This is beneficial for further concentration and screening of the pharmaceutical intermediates, improving the uniformity of the product, and preventing clumping during transportation, which would affect the product quality.

[0026] The working principle of this utility model is as follows: In use, the concentrated pharmaceutical intermediate is injected into the receiving tank through the conveying pipe 8. At this time, the control motor is started, driving the main shaft 1001 to rotate. Simultaneously, the top of the main shaft 1001 drives the connecting shaft 904 and the receiving tank 901 to rotate. After the pharmaceutical intermediate falls into the receiving tank 901, it flows along the dispensing block 902 into the discharge pipe 903. At this time, the pressure device 6 is activated to pressurize the dispensing tank. As the discharge pipe 903 is driven to rotate by the receiving tank 901, the pharmaceutical intermediate, under pressure, falls evenly from the discharge hole into the processing platform 905. The rotation of the connecting shaft 904 simultaneously drives the pressure roller 15 and the scraper 14 to rotate. Furthermore, the pressure roller 15 removes the pharmaceutical intermediate retained on the surface of the processing platform 905. The intermediate is crushed again. The scraper 14 scoops up and spreads the crushed pharmaceutical intermediate. The pressure roller 15 and the scraper 14 work simultaneously. The end away from the connecting shaft 904 drives the pulley 13 to roll in the chute 12. The processed pharmaceutical intermediate falls through the mesh of the processing platform 905 onto the surface of the filter cover 1002. The main shaft 1001 drives the connecting shaft 904 and the receiving bucket 901 to rotate the filter cover 1002 and the drive ring 1004. At this time, the granular pharmaceutical intermediate is slowly rotated along the filter cover 1002 and thrown into the slag discharge trough 1003 to wait for centralized processing. The qualified pharmaceutical intermediate falls into the bottom of the collection bin 2 after being filtered by the filter cover 1002. At this time, the pusher 1005 stirs to prevent the pharmaceutical intermediate from clumping and pushes it towards the discharge pipe 16 for conveying.
