Then, the larger raw materials enter the crushing cylinder from the sliding cylinder for crushing.

Description

Technical Field

[0001] This utility model relates to the field of pulverization technology, specifically to a device for pulverizing and pretreating heparin sodium raw materials. Background Technology

[0002] Sodium heparin can interfere with many aspects of the coagulation process and has anticoagulant effects both in vivo and in vitro. The production of sodium heparin requires the raw materials to be pulverized and pretreated.

[0003] A search revealed an existing patent (publication number: CN220824904U) that discloses a raw material crushing device for heparin sodium production, comprising a housing with a lid fixedly connected to the top, and a motor fixedly connected to the top of the lid. The advantages of this invention are: when crushing heparin sodium, the raw material crushing device adds heparin sodium into the housing through a feed pipe, starts the motor to drive the crushing blades on the stirring rod to crush the heparin sodium, and collects the crushed heparin sodium by falling onto a guide plate and being discharged from the outlet. Incompletely crushed heparin sodium falls onto a filter plate, and then the material pump is started, and the guide pipe draws the heparin sodium back into the housing for further crushing until it is discharged from the outlet. By repeatedly crushing the heparin sodium, the problem of incomplete crushing and poor crushing effect caused by only grinding and pushing the material inside the conveying tank with a spiral blade is solved.

[0004] It works by sucking up incompletely crushed raw materials and crushing them again, but it has shortcomings. First, it may suck up raw materials that have already been completely crushed and passed through. Second, it does not have a vibration mechanism, so some raw materials may get stuck inside the filter plate, causing the filter plate to become clogged, which makes it difficult for the crushed raw materials to pass through.

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a heparin sodium raw material crushing and pretreatment device, including a crushing cylinder 4, a crushing motor 7 fixed at the top of the crushing cylinder 4, a crushing shaft 8 fixed through the crushing cylinder 4, a rectangular box 1 fixed at the bottom of the crushing cylinder 4, an interception mechanism 2 inside the rectangular box 1, the interception mechanism 2 including an interception mesh ring 209, a sliding shell 201 fixed at the right side of the rectangular box 1, two rotating rods 208 rotatably connected inside the sliding shell 201 and inside the rectangular box 1, the rotating rods 208 being located inside the interception mesh ring 209, the right end of the interception mesh ring 209 passing through the rectangular box 1, a funnel 9 fixed at the upper surface inside the rectangular box 1, a fixed shell 203 fixed at the right side of the sliding shell 201, two transmission rods 206 rotatably connected inside the fixed shell 203, a rotating belt 211 sleeved on the outer side of the two transmission rods 206, multiple conveying plates 210 fixed on the outer wall of the rotating belt 211, and a sliding plate 210 fixed at the bottom of the fixed shell 203. The bottom of the sliding cylinder 204 and the top of the crushing cylinder 4 are fixedly connected. The front surface of the fixed shell 203 is fixed with a conveyor motor 202. The output shaft of the conveyor motor 202 is fixedly connected with the lower transmission rod 206. The rear surface of the sliding shell 201 is rotatably connected with a rotating rod 213. The outer walls of the lower transmission rod 206 and the rotating rod 213 are both fixed with conveyor wheels 212. The outer sides of the two conveyor wheels 212 are fitted with conveyor belts 207. The outer walls of the rotating rod 213 and the right rotating rod 208 are both fixed with gears 205. The two gears 205 are meshed together. The top of the crushing cylinder 4 is fixed with a feed hopper 5, which can further crush larger raw materials. The intercepting mesh ring 209 is made of steel wire mesh, which is durable and not easily damaged. The bottom of the funnel 9 is in contact with the top of the intercepting mesh ring 209. An opening is opened on the right side of the bottom of the funnel 9 to prevent raw materials from splashing. The rectangular box 1 is equipped with a collection box 3 to collect the crushed raw materials.

[0023] Furthermore, the interception net ring 209 is equipped with a striking mechanism 6 inside. The striking mechanism 6 includes a round rod 603. The front end of the round rod 603 is rotatably connected to the front inner surface of the rectangular box 1. The rear end of the round rod 603 passes through the rectangular box 1. Two striking plates 604 are fixed to the outer wall of the round rod 603. The striking plates 604 strike the interception net ring 209, which can cause smaller materials to fall. The outer walls of the rotating rod 208 and the outer walls of the round rod 603 are both fixed with transmission wheels 601. The outer sides of the two transmission wheels 601 are fitted with transmission belts 602. The diameter of the right transmission wheel 601 is larger than the diameter of the left transmission wheel 601, which can make the round rod 603 rotate and increase the rotational speed of the round rod 603.

[0024] During operation, the crushed raw materials fall onto the intercepting mesh ring 209. Smaller materials pass through the intercepting mesh ring 209 and fall downwards, while larger materials are intercepted by the intercepting mesh ring 209. The conveyor motor 202 is started, which drives the lower transmission rod 206 to rotate. The lower transmission rod 206 drives the rotating belt 211 to rotate, and the rotating belt 211 moves the conveyor plate 210. At the same time, the lower transmission rod 206 drives the rotating rod 213 to rotate through the conveyor wheel 212 and the conveyor belt 207. The rotating rod 213 drives the right rotating rod 208 to rotate through the gear 205. The right rotating rod 208 drives the intercepting mesh ring 209 to rotate. In this way, the intercepting mesh ring 209 moves the larger materials to the right side and then falls into the sliding shell 201 and slides into the fixed shell 203. The conveyor plate 210 conveys the larger materials upwards, and then the larger materials enter the crushing cylinder 4 from the sliding cylinder 204 for crushing.
