Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical technology, specifically relating to a pharmaceutical powder conveying pipeline that is easy to clean. Background Technology

[0002] Pharmaceutical powders refer to powdered substances made from drug raw materials, excipients, etc. through physical or chemical methods. They are common intermediates or formulations in the pharmaceutical field and play an important role in drug production, research and development, and application.

[0003] After powder preparation, it needs to directly enter the next process, such as mixing, granulation, tableting, capsule filling, etc., and when the distance between the equipment in each process is short or there is a fixed route, the powder is usually transported automatically through pipelines.

[0004] After transporting drug powder, the pipeline is prone to leaving powder residue inside, which is inconvenient for workers to clean. When the pipeline is used to transport multiple drugs, such as raw materials with different active ingredients, the residual powder can easily mix into the next product, leading to abnormal content of active ingredients, excessive impurities, or even changes in pharmacological effects. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical powder conveying pipe that is easy to clean, so as to solve the problem that existing pipes are prone to leaving powder residue inside after conveying pharmaceutical powder, making them difficult to clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pharmaceutical powder conveying pipe that is easy to clean includes a pipe body, an auxiliary mechanism provided on the arc surface of the pipe body, the auxiliary mechanism including a recessed hole opened on the arc surface of the pipe body, a cover plate provided on the inner wall of the recessed hole, a water pipe installed on the surface of the cover plate, and a plurality of nozzles connected to the arc surface of the water pipe, with the ends of the plurality of nozzles away from the water pipe penetrating the cover plate.

[0008] Preferably, one end of the pipe body has two locking holes, and locking rods are slidably inserted into the inner walls of the two locking holes. A connecting plate is fixedly connected to the end of the two locking rods away from the pipe body. A round rod is rotatably connected to the surface of the connecting plate, and the end of the round rod close to the pipe body is fixedly connected to the cover plate.

[0009] Preferably, the clamping rod and the clamping hole are interference-fitted, and the two clamping holes are symmetrically distributed about the transverse central axis of the pipe body.

[0010] Preferably, a motor is fixedly installed on the arc surface of the pipe body, a first gear is fixedly connected to the output end of the motor, and a second gear is fixedly connected to the arc surface of the round rod.

[0011] Preferably, teeth are provided on one side of the outer wall of the first gear.

[0012] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the connecting plate and the second gear, respectively.

[0013] Preferably, the cover plate has an arc-shaped cross-section, and the multiple nozzles are evenly distributed on the arc surface of the water pipe.

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

[0015] 1. This utility model uses a nozzle to spray cleaning fluid into the inside of the pipe body, thereby removing residual powder from the inner wall of the pipe body. It is convenient and quick. With the interlocking of the locking holes and locking rods, the cover plate can be disassembled and assembled, making it convenient for workers to wipe away water stains inside the pipe body after cleaning.

[0016] 2. This utility model utilizes the mutual transmission between the first gear and the second gear to enable the cover plate to rotate. Under the elastic force of the torsion spring, the cover plate can rebound, thereby achieving the effect of repeatedly rotating the cover plate back and forth. This allows the water sprayed from the nozzle to more comprehensively cover the inner wall of the pipe body, improving the cleaning effect inside the pipe body. Attached Figure Description

[0022] 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.

[0023] Reference Figures 1-4 As shown, this utility model provides a pharmaceutical powder conveying pipe that is easy to clean, including a pipe body 1. An auxiliary mechanism 2 is provided on the arc surface of the pipe body 1. The auxiliary mechanism 2 includes a recess 201 opened on the arc surface of the pipe body 1. A cover plate 202 is provided on the inner wall of the recess 201. A water pipe 204 is installed on the surface of the cover plate 202. Multiple nozzles 203 are connected to the arc surface of the water pipe 204. The ends of the multiple nozzles 203 away from the water pipe 204 all penetrate the cover plate 202.

[0024] In this embodiment, the cover plate 202 has an arc-shaped cross-section, which can better cover the concave hole 201. Multiple nozzles 203 are evenly distributed on the arc surface of the water pipe 204. The water pipe 204 needs to be connected to an external water source so that the cleaning liquid can be sprayed out from the nozzles 203.

[0025] In an optional embodiment: two locking holes 206 are provided at one end of the pipe body 1, and locking rods 207 are slidably inserted into the inner walls of the two locking holes 206. A connecting plate 208 is fixedly connected to the end of the two locking rods 207 away from the pipe body 1. A round rod 205 is rotatably connected to the surface of the connecting plate 208. The end of the round rod 205 near the pipe body 1 is fixedly connected to the cover plate 202.

[0026] It should be noted that the clamp rod 207 and the clamp hole 206 are interference fit. The two clamp holes 206 are symmetrically distributed about the transverse central axis of the pipe body 1. After cleaning, the clamp rod 207 can be pulled out from the clamp hole 206, so that the cover plate 202 can be removed from the recess 201, so as to quickly wipe the water stains inside the pipe body 1 clean.

[0027] In an optional embodiment: a motor 209 is fixedly installed on the arc surface of the pipe body 1, a first gear 210 is fixedly connected to the output end of the motor 209, and a second gear 211 is fixedly connected to the arc surface of the round rod 205.

[0028] It should be noted that the first gear 210 has teeth on one side of its outer wall, and the first gear 210 will intermittently mesh with the second gear 211.

[0029] In an optional embodiment: a torsion spring 212 is sleeved on the arc surface of the round rod 205, and the two ends of the torsion spring 212 are fixedly connected to the connecting plate 208 and the second gear 211, respectively.

[0030] It should be noted that the number of teeth on the tooth surface of the first gear 210 is incomplete. The first gear 210 will intermittently mesh with the second gear 211, and the torsion spring 212 will be in a torsional state. When the first gear 210 and the second gear 211 are not meshed, the torsion spring 212 will rebound. This process repeats, achieving the effect of making the cover plate 202 swing back and forth repeatedly, causing the cleaning fluid sprayed from the nozzle 203 to swing back and forth, thus covering the inner wall of the pipe body 1 more comprehensively and improving the cleaning effect.

[0031] The working principle of this utility model is as follows: During use, after the staff transports the powder through the pipe body 1, when it is necessary to clean the inside of the pipe body 1, a water source is connected to the water pipe 204, causing the cleaning solution to spray out from the nozzle 203. At the same time, the motor 209 is started, driving the first gear 210 to rotate. The first gear 210 will transmit power to the second gear 211. Because the number of teeth on the tooth surface of the first gear 210 is incomplete, the first gear 210 will intermittently mesh with the second gear 211. The torsion spring 2... 12 will be in a torsional state. When the first gear 210 and the second gear 211 are not meshed, the torsion spring 212 rebounds. This process repeats, achieving the effect of repeatedly swinging the cover plate 202 back and forth, causing the cleaning fluid sprayed from the nozzle 203 to swing back and forth, thus covering the inner wall of the pipe body 1 more comprehensively and improving the cleaning effect. After cleaning, the clamp 207 can be pulled out from the clamp hole 206, and the cover plate 202 can be removed from the recess 201, so that the water stains inside the pipe body 1 can be wiped clean quickly.
