Description

Technical Field

[0001] This utility model relates to the field of difenidol hydrochloride production technology, specifically to a crushing mechanism for difenidol hydrochloride production. Background Technology

[0002] Difenidol hydrochloride can improve vertebrobasilar artery blood supply, regulate vestibular system function, and inhibit the vomiting center, thus having anti-vertigo and antiemetic effects. In the production of difenidol hydrochloride, the raw material needs to be ground into powder using a pulverizing device for subsequent processing. Currently, in existing pulverizing mechanisms, the sieve plate is located inside the casing. As the powder passes through the sieve plate, the holes on the sieve plate inevitably become blocked. Furthermore, the integral casing makes it inconvenient to maintain or repair the crushing components and the sieve plate, resulting in inconvenient use.

[0003] A search revealed a high-efficiency pulverizing device for the production of difenidol hydrochloride, with publication number CN220590188U. This device includes a pulverizing box and a feeding hopper, as well as a pair of crushing rollers, a guide hopper, a grinding cylinder, grinding blocks, a rotary drive mechanism, and a receiving box. The feeding hopper is fixed to the top left of the pulverizing box, with its diameter extending through the top of the pulverizing box. A pair of crushing rollers rotating in opposite directions are installed inside the hopper. The guide hopper is fixed below the feeding hopper inside the pulverizing box. The grinding cylinder is fixed to the bottom end of the guide hopper, and grinding blocks are installed inside via the rotary drive mechanism. Several through holes are evenly distributed at the bottom of the grinding cylinder. The receiving box is removable and located in the lower part of the pulverizing box. This technical solution also suffers from the aforementioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a pulverizing mechanism for the production of difenidol hydrochloride, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing mechanism for the production of difenidol hydrochloride, comprising a bottom shell, a top shell above the bottom shell, a crushing shell disposed within the cavity formed by the top shell and the bottom shell, a sieve plate installed inside the crushing shell, the sieve plate being exposed when the top shell and the bottom shell are separated, and a support block being fixedly connected to the inner wall of the bottom shell, the support block being fixedly connected to the crushing shell.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-6 A crushing mechanism for the production of difenidol hydrochloride includes a bottom shell 1 and a top shell 2 that are joined together. The bottom shell 1 and the top shell 2 form a detachable shell. A long strip-shaped discharge port 22 is provided on the lower front side of the bottom shell 1. A recycling box 23 is placed on the bottom of the inner wall of the bottom shell 1. A handle 24 is fixedly connected to the front side of the recycling box 23. The size of the discharge port 22 is larger than the size of the recycling box 23. Thus, by pulling the recycling box 23 with the handle 24, the recycling box 23 can be taken out from the bottom shell 1 through the discharge port 22.

[0017] A horizontally mounted mounting plate 5 is fixedly welded to both the left and right sides of the bottom shell 1. A hydraulic cylinder 6, providing linear driving force, is mounted on the mounting plate 5. The output shaft of the hydraulic cylinder 6 extends upwards and is fixedly connected to a drive plate 7. The drive plate 7 is fixedly connected to the top shell 2. When it is necessary to separate the bottom shell 1 and the top shell 2, an external power supply is used to power the hydraulic cylinder 6, causing it to operate. The hydraulic cylinder 6 then drives the drive plate 7 upwards, which in turn drives the top shell 2 upwards, thus separating the bottom shell 1 and the top shell 2. The hydraulic cylinder 6 is existing technology, and powering it and making it operate is common knowledge; therefore, this technical solution will not elaborate on it. To protect the hydraulic cylinder 6, two vertically extending telescopic rods 21 are fixedly connected to the top of the mounting plate 5. The telescopic rods 21 can extend and retract, and their top ends are fixedly connected to the bottom of the drive plate 7. The telescopic rods 21 limit the mounting plate 5 to only undergo linear pitch-changing movement with the drive plate 7, thus preventing the output shaft of the hydraulic cylinder 6 from being subjected to other forces in the vertical direction.

[0018] A feed chamber 8, open at both ends, is fixedly connected to the top shell 2. The bottom of the feed chamber 8 extends into the interior of the top shell 2. Two crushing motors 9 are mounted on one side of the feed chamber 8. A crushing cylinder 10 is fixedly connected to the output shaft of the crushing motor 9. The crushing cylinder 10 is specifically composed of a cylinder and crushing teeth on the surface of the cylinder. The distance between the two crushing cylinders 10 is extremely small. The two crushing motors 9 are exactly the same, but they drive the two crushing cylinders 10 to rotate in different directions. (See the attached instruction manual.) Figure 3From the perspective of the crushing motor 9 on the left, the crushing cylinder 10 will rotate clockwise, and the crushing motor 9 on the right will rotate counterclockwise. This will cause the two crushing cylinders 10 to squeeze and crush the raw materials towards the center. Two inclined plates 11 are fixedly connected to the inner wall of the feed shell 8. The front and rear sides of the inclined plates 11 are fixedly connected to the front and rear sides of the inner wall of the feed shell 8, respectively. The inclined plates 11 are designed to guide the material, so that when the raw materials are fed into the feed shell 8, the material will concentrate and move towards the center.

[0019] Support blocks 26 are fixedly connected to the left and right sides of the inner wall of the bottom shell 1. The two support blocks 26 are fixedly connected by a crushing shell 3. A connecting rod 12 is fixedly connected to the rear side of the feed shell 8. A vertical plate 13 is fixedly connected to the rear side of the connecting rod 12. A horizontal plate 14 is fixedly connected to the bottom of the vertical plate 13. A clamping plate 15 is fixedly connected to the front side of the horizontal plate 14. During the processing, the rear side of the crushing shell 3 is integrally formed with a groove that matches the clamping plate 15. The clamping plate 15 is movably engaged in the groove, thus using the clamping plate 15 to block the groove on the crushing shell 3. When the feed shell 8 moves upward... When the clamping plate 15 disengages from the slot, a crushing motor 16 is fixedly installed on one side of the clamping plate 15 facing the outside of the crushing shell 3. A crushing roller 17 located inside the crushing shell 3 is fixedly connected to the output shaft of the crushing motor 16. The gap between the crushing roller 17 and the inner wall of the crushing shell 3 is extremely small. Thus, the material crushed by the crushing cylinder 10 is again squeezed against the inner wall of the crushing shell 3 by the crushing roller 17 for crushing, making the raw material of difenidol hydrochloride more thoroughly crushed. The two crushing motors 16 drive the two crushing rollers 17 to rotate in opposite directions. (See the attached instruction manual.) Figure 3 As you can see, the crushing motor 16 on the left drives the crushing roller 17 to rotate counterclockwise, while the crushing motor 16 on the right drives the crushing roller 17 to rotate clockwise. In this way, the raw materials falling from above will be rolled into the crushing roller 17 and crushed and squeezed at the point where the gap between the crushing roller 17 and the crushing shell 3 is the smallest. In order to cover the gap between the two crushing rollers 17, an upper arc plate 20 is fixedly connected to the inner wall of the crushing shell 3. The upper arc plate 20 is convex, thus forming an arc-shaped sliding surface. The falling raw materials will slide down the arc-shaped sliding surface more smoothly. The bottom of the feed shell 8 is inside the crushing shell 3. This setting can effectively prevent the falling materials from splashing to the outside of the crushing shell 3.

[0020] The bottom of the crushing shell 3 is an open, elongated slot. A sieve plate 4 is installed inside the slot, and a mounting bracket 18 is fixedly connected to the bottom of the sieve plate 4. The mounting bracket 18 is bolted to the crushing shell 3. The sieve plate 4 allows for direct screening of the crushed raw materials. This technical solution ensures thorough crushing of the raw materials. Therefore, in practical applications, the crushed raw materials generally pass through the sieve plate 4, leaving very few large particles on the top of the sieve plate 4, although not none. Furthermore, the bottom shell 1 and top shell 2 are easily separated. After separation, the crushing roller 17 moves to the outside of the crushing shell 3, exposing the top of the sieve plate 4. Workers can use a cleaning box or similar items to remove the small amount of large particles screened off the top of the sieve plate 4. Then, the bottom shell 1 and top shell 2 are reset, and the removed large particles are added back into the feed shell 8 for further crushing of the raw materials.

[0021] To prevent raw materials from remaining at the top corners of the screen plate 4, two strip-shaped triangular bars 25 are fixedly connected to the top of the screen plate 4. The sides of the triangular bars 25 are in contact with the crushing shell 3. Static screening can easily lead to screen hole blockage and is not conducive to screening. Therefore, this technical solution installs a vibrator 19 on the front side of the inner wall of the bottom shell 1. The specific structure of the vibrator 19 is the same as that of the existing fascia gun. Both the crushing shell 3 and the screen plate 4 are made of conventional metal. When the vibrator 19 is working, its working head will vibrate and impact the crushing shell 3. Due to the characteristics of metal vibration, the screen plate 4 will produce an amplitude movement that is not easily discernible to the naked eye. This is conducive to the screening and falling of the material at the top of the screen plate 4. After the crushing shell 3 vibrates, it is also conducive to the sliding of the raw material at the top of the upper arc plate 20.

[0022] Finally, all electric drive devices in this technical solution have control switches, which is common knowledge. Electric drive devices need switches. This technical solution is not an improvement on the switches, so there is no detailed explanation of the control switches.

[0023] In use, raw materials are fed into the feed chamber 8. The inclined plate 11 guides the raw materials. The control switch is turned on, and the crushing motor 9 starts working, driving the crushing cylinder 10 to rotate. The two crushing cylinders 10 work together to perform preliminary crushing of the raw materials. The pre-crushed raw materials fall onto the top of the upper arc plate 20 and slide to both sides. The grinding motor 16 then drives the grinding roller 17 to rotate. The grinding roller 17 engages with the inner wall of the grinding chamber 3 to further crush the raw materials. Finally, the material falls onto the top of the screen plate 4. The vibrator 19 also works, causing the crushing shell 3 to vibrate. Finally, the material screened by the screen plate 4 falls into the recycling box 23. When it is necessary to maintain the screen plate 4 or clean the raw materials that may adhere to the inner wall of the crushing shell 3 and the crushing roller 17, the hydraulic cylinder 6 is activated by the control switch. The hydraulic cylinder 6 drives the drive plate 7 to move upward, the telescopic rod 21 extends, the bottom shell 1 and the top shell 2 separate, and the crushing roller 17 moves to the outside of the crushing shell 3, so that the crushing roller 17 and the top of the screen plate 4 are exposed.
