A terramycin hydrochloride air stream conveyor

Abstract

The application relates to a terramycin hydrochloride airflow conveying machine, belonging to the technical field of terramycin hydrochloride conveying technology, which comprises an airflow feeding pump, an inner pipe discharging mechanism arranged on the airflow feeding pump, an outer pipe resonance mechanism arranged in the inner pipe discharging mechanism and a powder sub-conveying mechanism arranged on the outer pipe resonance mechanism. The airflow feeding pump is used for providing airflow kinetic energy for conveying the powdered terramycin hydrochloride. When the airflow feeding pump is operated, the constant-pressure airflow released outwardly passes through the inner pipe discharging mechanism. With the conveying of the airflow to the vibration bin assembly, the thrust exerted by the partial air pressure can make the pressure-bearing gaskets vibrate at high frequency. The inner pipe clamped by the multiple pressure-bearing gaskets can continuously release the airflow in a corrugated state outwardly, so that the loss of the powdered terramycin hydrochloride on the pipe wall due to static placement can be avoided.

Description

Technical Field

[0001] This invention relates to the field of oxytetracycline hydrochloride delivery technology, specifically to an oxytetracycline hydrochloride pneumatic conveyor. Background Technology

[0002] Oxytetracycline hydrochloride is an antibiotic derived from a culture of Streptomyces oxytetracycline. It inhibits protein synthesis in susceptible microorganisms by reversibly binding to the 30S ribosomal subunit, thereby inhibiting the binding of tRNA and ribosomes and achieving an antibacterial effect.

[0003] Currently, oxytetracycline hydrochloride is prepared from spores and molds in a moist state. This moist state needs to be prepared in multiple specifications according to the requirements of the application. The final moist state can be divided into powder or granules. The dried powder needs to be transported by pneumatic conveying. However, the current pneumatic conveying device for oxytetracycline hydrochloride has certain defects. The airflow velocity and pressure are constant, so the airflow can only transport the powdered oxytetracycline hydrochloride in one direction. However, because the airflow is not fluctuating, the powdered oxytetracycline hydrochloride will be lost on the inner wall of the pipe. At the same time, the powder accumulated on the inner wall of the pipe is easily interfered with by the humid gas in the environment after the operation is stopped, resulting in clumping and other contamination.

[0004] In view of this, an oxytetracycline hydrochloride pneumatic conveyor was designed to solve the above problems. Summary of the Invention

[0014] In a preferred embodiment, the present invention may be further configured such that: the outer tube resonance mechanism further includes an annular gasket disposed outside the inner tube, and six evenly distributed first clamps are disposed inside the annular gasket, with fixing bolts installed on the internal threads of the first clamps;

[0015] Both ends of the first chuck are provided with chucks, and a slant plate is movably mounted on one of the chucks;

[0016] The outer end of the inclined plate is movably fitted with a second clamp, and the inside of the inclined plate is provided with a sliding groove;

[0017] The second clamp is installed on the end of the pressure-resistant outer tube.

[0018] In a preferred embodiment, the present invention may be further configured such that: a recessed hole is provided at the inner end of the nozzle, and an end post is provided in the recessed hole; a pressure relief plug is movably installed in the end post; and a compression spring is provided on the rod through which the pressure relief plug extends into the inner cavity of the nozzle.

[0019] The outer end of the pressure relief plug is provided with a slide rod, which consists of an extended guide rod and a slider. The slider is adapted to be installed in the slide groove, while the extended guide rod extends through the pressure distribution cover.

[0020] The inner wall of the nozzle is equipped with six sets of evenly distributed partition plates, and two adjacent partition plates are arranged on both sides of the pressure relief plug.

[0021] In a preferred embodiment, the present invention may be further configured such that the inner tube discharge mechanism also includes a sleeve installed outside the nozzle, and the end of the sleeve away from the nozzle is provided with six pads;

[0022] Furthermore, six feet are installed on the outer wall of the pressure-resistant outer tube.

[0023] In a preferred embodiment, the present invention may be further configured such that: the diversion assembly includes a transfer pipe disposed within the nozzle, one end of the transfer pipe being inserted into the port of the inner pipe, and the other end of the transfer pipe being inserted into the exhaust pipe at the top of the airflow feed pump;

[0024] The inner wall of the transfer pipe is provided with evenly distributed air holes, which are used to utilize part of the air pressure and to power the pressure relief plug and slide rod.

[0025] In a preferred embodiment, the present invention can be further configured such that: the powder conveying mechanism includes a wind chamber installed on the outer end of the inner pipe, the wind chamber having an overall T-shaped structure, and two transfer air ducts are installed on the two branch pipes of the wind chamber;

[0026] The transfer duct has an overall L-shaped structure, and an impeller is movably installed inside the transfer duct cavity;

[0027] A flow guide pad is installed in the middle of the air chamber cavity, and the flow guide pad is used to divide the direct airflow.

[0028] In a preferred embodiment, the present invention may be further configured such that the impeller consists of a shaft roller, a hub and blades, and one end of the shaft roller is provided with a bearing, which is installed in a hole in the inner wall of the transfer duct.

[0030] In a preferred embodiment, the invention may be further configured such that the anti-collision pad is made of rubber material.

[0031] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0032] 1. This invention sets up an independent airflow feeding pump on the path of the powdered oxytetracycline hydrochloride roller. When the airflow feeding pump is running, the constant pressure airflow released outward will pass through the inner tube discharge mechanism. As part of the airflow is transferred into the vibrating chamber assembly, the thrust applied by part of the air pressure can bear the pressure pads to vibrate at high frequency. Finally, the inner tube, which is held by multiple pressure pads, can continuously release the airflow outward in a corrugated state, thereby avoiding the loss of powdered oxytetracycline hydrochloride due to standing on the tube wall.

[0033] 2. This invention adds a transfer duct to the pipeline for conveying powdered oxytetracycline hydrochloride, and additionally installs a heating plate at the top of the transfer duct. As the airflow passes through the transfer duct and is dried by the heating plate under the transfer action of the impeller, it can effectively ensure that the powdered oxytetracycline hydrochloride will not experience secondary moisture during transfer in the extended pipeline.

[0034] 3. This invention, by setting multiple pressure-distributing hoods evenly distributed at the inner end of the nozzle, allows some airflow to enter through the air holes and then be transferred to the cavity between the nozzle and the transfer pipe. The airflow, after being partitioned by the partition plate, can then drive the pressure relief plug to vibrate regularly under the seepage-proof protection of the pressure-distributing hoods. This avoids insufficient airflow pressure while ensuring the strength of the pressure-bearing gasket on the inner pipe, thereby ensuring that the airflow effectively transfers the oxytetracycline hydrochloride powder in a corrugated manner.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0052] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0053] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an oxytetracycline hydrochloride pneumatic conveyor.

[0054] Example 1:

[0055] Combination Figures 1-11 As shown, the present invention provides an oxytetracycline hydrochloride pneumatic conveyor, comprising a pneumatic feed pump 100, an inner tube discharge mechanism 200 disposed on the pneumatic feed pump 100, an outer tube resonance mechanism 300 disposed within the inner tube discharge mechanism 200, and a powder distribution mechanism 400 disposed on the outer tube resonance mechanism 300. The pneumatic feed pump 100 is used to supply air to oxytetracycline hydrochloride powder, the inner tube discharge mechanism 200 is used to apply resonance energy to the outer tube resonance mechanism 300 using part of the airflow, the outer tube resonance mechanism 300 is used to provide ripple vibration to the airflow, and the powder distribution mechanism 400 is used to provide a heat drying channel for the transferred airflow and oxytetracycline hydrochloride.

[0056] The inner tube discharge mechanism 200 includes a nozzle 210 disposed on the exhaust pipe at the top of the airflow feed pump 100, a continuous pressurization component 260 disposed inside the nozzle 210, a plurality of pressure-dividing hoods 230 evenly distributed at the inner end of the nozzle 210, a flow-converting component 240 disposed inside the nozzle 210, and an inner tube 250 disposed inside the nozzle 210.

[0057] The outer tube resonance mechanism 300 includes a vibratory chamber assembly 360, and an inner tube 250 is disposed inside the vibratory chamber assembly 360. The vibratory chamber assembly 360 is used to provide resonant kinetic energy for the airflow inside the inner tube 250. An annular pad 310 is disposed outside the inner tube 250. Six evenly distributed first clamps 320 are disposed inside the annular pad 310. Fixing bolts 330 are threaded on the first clamps 320.

[0058] The oscillation assembly 360 includes a pressure-resistant outer tube 361, and the inner wall of the pressure-resistant outer tube 361 is provided with evenly distributed insertion holes;

[0059] Four sets of evenly distributed columns 364 are installed at both ends of the pressure-resistant outer tube 361, and pressure-bearing gaskets 362 are movably installed on two adjacent columns 364.

[0060] Two springs 365 are provided on the column 364. One spring 365 is located on the outside of the pressure-bearing pad 362, and the other spring 365 is located on the inside of the pressure-bearing pad 362.

[0061] The pressure-bearing gasket 362 has evenly distributed U-shaped protrusions, and the U-shaped protrusions are adapted to penetrate into the insertion hole, while multiple anti-collision pads 370 are provided on the U-shaped protrusions.

[0062] The anti-collision pad 370 is attached to the outer wall of the inner tube 250, and the anti-collision pad 370 is made of rubber material;

[0063] Multiple bushings 363 are installed inside the pressure-bearing gasket 362;

[0064] Both ends of the first chuck 320 are provided with chucks, and a slant plate 340 is movably installed on one of the chucks;

[0065] A second clamp 350 is movably installed at the outer end of the inclined plate 340, and a sliding groove is provided inside the inclined plate 340;

[0066] The second clamp 350 is installed on the end of the pressure-resistant outer tube 361.

[0067] After oxytetracycline hydrochloride is produced in multiple steps to form a wet product, the wet product needs to be processed into powder or granules according to the requirements. Unlike the conveying of granular oxytetracycline hydrochloride, the powder material mainly needs to be transferred by a pneumatic conveying device. However, the existing pneumatic conveying device has certain defects. Since the air pressure is constant, without additional pressure, some oxytetracycline hydrochloride powder will adhere to the wall of the feeding pipe, resulting in the loss of some oxytetracycline hydrochloride powder. At the same time, due to the influence of the pipe length, once the device stops, the external humid air will cause the material adhering to the pipe wall to become wet and clump together, thus causing a change in quality.

[0068] The device needs to be installed on the path for preparing oxytetracycline hydrochloride powder. Then, the airflow feed pump 100 is started, at which point the transfer pipe 241 can deliver airflow into the inner pipe 250. Part of the airflow is transferred through the air hole 242 into the cavity between the nozzle 210 and the transfer pipe 241. At this time, part of the air pressure, guided by the six sets of partition plates 265, will eventually push the six pressure relief plugs 262 to extend regularly. The sliding rod 264 installed at the outer end of the pressure relief plug 262 will then apply pressure to the inclined plate 340. At this time, the inclined plate 340 and its outer second clamp 3... When 50 is compressed, the pressure-bearing gasket 362 will work with the anti-collision pad 370 to apply a vibration wave to the outer wall of the inner tube 250. At this time, the airflow passing through the inner cavity of the inner tube 250 can enter the two transfer ducts 430 in the form of a vibration wave. Under the action of the airflow, the impeller 440 rotates. At this time, the airflow in the feeding pipe connected to the bottom of the transfer duct 430 can be in a regular oscillation. At the same time, it can assist in drying the airflow, thereby avoiding the problem that oxytetracycline hydrochloride is easy to adhere to the pipe wall due to constant airflow pressure during the transfer process, and at the same time, avoiding the powder from becoming damp and clumping.

[0069] Example 2:

[0070] Combination Figure 4 and Figure 5 As shown, based on Embodiment 1, the inner tube discharge mechanism 200 also includes a sleeve 220 installed outside the nozzle 210, and the end of the sleeve 220 away from the nozzle 210 is provided with six pads.

[0071] Furthermore, six feet are installed on the outer wall of the pressure-resistant outer tube 361;

[0072] The nozzle 210 has a recessed hole at its inner end, and an end post 261 is provided in the recessed hole. A pressure relief plug 262 is movably installed in the end post 261. A pressure relief plug 262 is provided on a rod that extends through the inner cavity of the nozzle 210 and has a compression spring 263.

[0073] The outer end of the pressure relief plug 262 is provided with a slide rod 264, which is composed of an extended guide rod and a slider. The slider is adapted to be installed in the slide groove, while the extended guide rod extends through the pressure distribution cover 230.

[0074] The inner wall of the nozzle 210 is equipped with six sets of evenly distributed partition plates 265, and two adjacent partition plates 265 are arranged on both sides of the pressure relief plug 262.

[0075] Preferably, when a portion of the airflow enters the cavity separated by the two size partition plates 265, the air pressure there will squeeze the pressure relief plug 262, and eventually the pressure relief plug 262 will extend outward. At the same time, the slide rod 264 fixed to the outer end of the pressure relief plug 262 will vibrate the inclined plate 340.

[0076] As the air pressure is released into the inner cavity of the pressure distribution cover 230, the pressure relief plug 262, which is pressurized by the pressure spring 263, will quickly reset and seal the inner end hole of the nozzle 210, thereby maintaining a constant air pressure. The pressure bearing pad 362 can then apply a resonant force to the inner tube 250 within the fixed pressure-resistant outer tube 361.

[0077] Example 3:

[0078] Combination Figure 5 and Figure 10 As shown, based on Embodiment 1, the transfer assembly 240 includes a transfer pipe 241 disposed in the nozzle 210, and one end of the transfer pipe 241 is inserted into the port of the inner pipe 250, while the other end of the transfer pipe 241 is inserted into the exhaust pipe at the top of the airflow feed pump 100.

[0079] The inner wall of the transfer pipe 241 is provided with evenly distributed air holes 242, and the air holes 242 are used to utilize part of the air pressure and provide energy to the pressure relief plug 262 and the slide bar 264.

[0080] The threaded end of the nozzle 210 is installed on the threaded section of the exhaust pipe at the top of the airflow feed pump 100, and the inner wall of the nozzle 210 is provided with a slot that is adapted to be snapped into the annular protrusion of the transfer pipe 241.

[0081] Preferably, both the transfer pipe 241 and the nozzle 210 are made of stainless steel, and the six sets of partition plates 265 are evenly installed in the inner cavity of the nozzle 210. After the airflow passes through the air hole 242 and enters the cavity divided by the six sets of partition plates 265, the six pressure relief plugs 262 can be pressurized evenly. At this time, the inner pipe 250 located in the middle of the inner cavity of the pressure-resistant outer pipe 361 can be subjected to constant pressure at multiple angles, thereby ensuring that the airflow passing through the inner cavity of the inner pipe 250 is transferred outward in a wavy state, so as to facilitate the application of pressure resonance force to the oxytetracycline hydrochloride powder and avoid the powder from adhering to the pipe wall.

[0082] Example 4:

[0083] Combination Figure 3 As shown, based on Embodiment 1, the powder conveying mechanism 400 includes a wind chamber 410 installed on the outer end of the inner pipe 250. The wind chamber 410 has a T-shaped structure, and two transfer air ducts 430 are installed on the two branch pipes of the wind chamber 410.

[0084] The transfer duct 430 has an overall L-shaped structure, and an impeller 440 is movably installed inside the transfer duct 430.

[0085] A flow guide pad 420 is installed in the middle of the inner cavity of the air chamber 410, and the flow guide pad 420 is used to divide the direct airflow.

[0086] The impeller 440 consists of a shaft roller, a hub and blades, and a bearing is provided at one end of the shaft roller, which is installed in a hole in the inner wall of the transfer duct 430.

[0087] Preferably, a heating plate can be installed at the top of the transfer duct 430. When the heating plate is installed at the top of the transfer duct 430, the heating plate can radiate heat energy into the inner cavity of the transfer duct 430 after being powered on. As the airflow passes through the impeller 440 and is driven to rotate, the airflow that has been radiated and heated can be input from the bottom of the transfer duct 430 into the external feeding pipe, thereby avoiding moisture during material transportation.

[0088] When the transfer duct 430 is directly connected to the wet product feeding pipe, as the wet product enters the transfer duct 430, the material pushed to the bottom of the inner cavity of the transfer duct 430 by the rotating impeller 440 can be dried and transported by airflow. At this time, the airflow feeding pump 100 needs to deliver hot airflow. The corrugated hot airflow can directly dry and transport the wet product oxytetracycline hydrochloride.

[0089] The working principle and usage process of this invention: After oxytetracycline hydrochloride is prepared by fermentation and extraction of spores or molds, the mother liquor obtained by filtration needs to be acidified and filtered, and then decolorized to finally form a high-quality product. The high-quality product is in a moist state, so it needs to be dried. Finally, the dried powdered oxytetracycline hydrochloride can be transferred and bagged.

[0090] However, the dry powder of oxytetracycline hydrochloride is mainly transported by pneumatic conveying. Therefore, the powdered oxytetracycline hydrochloride transported by pneumatic conveying through special pipelines will cause adhesion to the pipe wall during the transfer process, which will cause a certain loss of oxytetracycline hydrochloride powder in the pipeline. The accumulated oxytetracycline hydrochloride powder on the inner wall of the pipeline over a long period of time, when disturbed by the airflow in the humid environment, will cause scale to form on the pipe wall.

[0091] When the airflow feed pump 100 of the device is started, the exhaust pipe at the top of the airflow feed pump 100 can release the airflow of the material in the conveying pipe. At this time, the airflow can enter from the transfer component 240 and be conveyed into the air chamber 410 through the inner pipe 250. Under the partitioning and diversion effect of the airflow guide pad 420, the two airflows after partitioning can enter the two transfer air ducts 430 respectively. The impeller 440 under the pressure of the airflow will be pushed and rotated. When the heat dissipation is installed at the top port of the transfer air duct 430, the oxytetracycline hydrochloride powder can be dried in the vortex state formed in the inner cavity of the transfer air duct 430 under the rotation of the impeller 440.

[0092] At the same time, the bottom end of the transfer duct 430 needs to be connected to an external pipe. Therefore, the heated airflow inside the transfer duct 430 can prevent the powder from clumping due to the interference of residual humid gas in the pipe during the transfer process.

[0093] In addition, some of the gas released from the exhaust pipe at the top of the airflow feed pump 100 will enter the cavity formed by the transfer pipe 241 and the nozzle 210 through the air hole 242. Under the partition of the six sets of partition plates, the air pressure in the six partitions can push the six pressure relief plugs 262 outward in a regular manner. At this time, the pressure relief plugs 262 will push the slide rod 264 outward, and the slider at the outer end of the slide rod 264 will apply pressure to the inclined plate 340 installed externally. Finally, the six inclined plates 340 can achieve high-frequency vibration. The second clamp 350 and the pressure bearing pad 362 connected to the outer end of the inclined plate 340 will work with the anti-collision pad 370 to apply vibration force to the inner tube 250. At this time, the airflow through the inner cavity of the inner tube 250 can form regular vibration ripples. At this time, the rippled airflow can shake off the powdered oxytetracycline hydrochloride on the tube wall, thereby avoiding the loss of powder on the tube wall due to the unfluctuated airflow.

[0094] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
