Description

Technical Field

[0001] This invention relates to the field of spray drying equipment technology, and in particular to a spray drying equipment for the preparation of S-adenosylmethionine p-toluenesulfonic acid sulfate. Background Technology

[0002] Spray drying towers are used for drying biopesticides, pharmaceuticals, and food microorganisms. In the preparation of S-adenosylmethionine p-toluenesulfonic acid sulfate, the concentrated solution needs to be introduced into the spray drying tower for drying to obtain the finished product. However, existing spray drying towers have the following problems in use:

[0003] 1. The storage tank for the concentrate is usually located on the ground. The concentrate needs to be introduced into the spray drying tower through a pump and pipeline. During the process of passing through the pipeline, some of the concentrate adheres to the inner wall of the pipeline, which reduces the utilization rate of the concentrate and reduces the amount of finished product.

[0004] 2. The finished product made from the concentrated liquid under the action of the spray drying tower is discharged through the discharge pipe. During this process, the discharged airflow contains a large amount of waste heat, and the utilization rate of this waste heat is low.

[0017] The beneficial effects of this invention are:

[0018] 1. By setting up a feeding mechanism, the storage pipe can be positioned above the spray drying tower, thereby reducing the travel distance of the concentrate into the spray drying tower and thus reducing the contact area between the concentrate and the pipe, thereby reducing adhesion. At the same time, the vertical setting of the feed pipe allows the partially adhered concentrate to slide downwards under the action of gravity, allowing it to be introduced into the spray drying tower, improving the utilization rate of the concentrate and thus increasing the yield of the finished product. Furthermore, the cleaning and suction structures actively clean and discharge the adhered concentrate, greatly reducing the impact of concentrate adhering to the inner wall of the pipe on the yield of the finished product.

[0019] 2. By setting up a cleaning structure and a suction structure, the concentrated liquid adhering to the inner wall of the feed pipe can be scraped and cleaned by the cleaning structure. With the suction structure, the cleaned concentrated liquid can be stored in the collection chamber. The concentrated liquid stored in the collection chamber can be discharged into the spray drying tower through the feed pipe by the suction structure. This effectively improves the utilization rate of the concentrated liquid and reduces the impact of the concentrated liquid adhering to the inner wall of the pipe on the finished product.

[0020] 3. By setting up auxiliary structures, during the process of the finished product made from the concentrate being exported from the inside of the spray drying tower by airflow, some of the finished product can be retained inside the connecting shell, reducing the difficulty of subsequent separation. At the same time, the residual heat in the airflow can be absorbed by the heat-conducting shell and heat exchange tubes, and the absorbed heat can be converted into other forms of energy for use.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In practical implementation: such as Figure 1-13As shown, a spray drying device for preparing S-adenosylmethionine p-toluenesulfonic acid sulfate includes: a spray drying tower 1, a blower 2 on one side of the spray drying tower 1, and a discharge pipe at the lower end of the surface of the spray drying tower 1; a feeding mechanism 3, which is located above the spray drying tower 1; wherein, the feeding mechanism 3 includes a storage tank 301 located above the spray drying tower 1, a feed pipe 303 connected to the top of the storage tank 301, a pump body 302 located inside the storage tank 301, a guide pipe 304 connected to the bottom of the pump body 302, and the guide pipe 304 connected to the inlet of the spray drying tower 1; the feeding mechanism 3 also includes a cleaning structure 31 located inside the guide pipe 304, which is used to clean the adhering material inside the guide pipe 304; the feeding mechanism 3 also includes a suction structure 32 located on the surface of the guide pipe 304. The suction structure 32 is used to remove the sticky material cleaned by the cleaning structure 31; the auxiliary structure 4 is set on the surface of the discharge pipe and is used to collect and reuse the residual heat after processing. By setting the storage tank 301 above the spray drying tower 1, the stroke of the concentrate introduced into the spray drying tower 1 can be reduced. By starting the pump body 302, the concentrate in the storage tank 301 can be introduced into the spray drying tower 1, and hot air is introduced into the spray drying tower 1 under the action of the blower 2, thereby spray drying the concentrate. The setting of the guide pipe 304 can avoid the situation where the guide pipe 304 of traditional equipment has many bends and is easy to stick to the concentrate. At the same time, it can reduce the discharge stroke of the concentrate and reduce the contact area between the concentrate and the guide pipe 304, thereby reducing the content of concentrate sticking to the inner wall of the pipe and thus increasing the yield of finished product.

[0037] like Figure 1-13 As shown, the cleaning structure 31 includes a first mounting shell 311 fixedly connected to the surface of the feed tube 304. A connecting ring 314 is rotatably connected to the inner wall of the feed tube 304. A toothed ring 317 is fixedly connected to the outer edge of the connecting ring 314. A connecting shaft 315 is provided on the inner side of the connecting ring 314. The lower end of the connecting shaft 315 extends through the connecting ring 314. Evenly distributed scrapers 316 are fixedly connected to the surface of the connecting shaft 315. The upper surface of the scrapers 316 is fixedly connected to the inner wall of the connecting ring 314, and the surface of the scrapers 316 is in contact with the inner wall of the feed tube 304. A drive motor 312 is provided at the bottom of the first mounting shell 311. The output shaft of the drive motor 312 passes through the first mounting shell 311 and is fixedly connected to a gear 313. The gear 313 meshes with a gear ring 317. A connecting pipe 3218 is connected to the surface of the guide tube 304. A through hole 3219 is opened at the other end of the connecting pipe 3218. A sealing ball 3220 is slidably connected to the inner wall of the connecting pipe 3218. One end of the sealing ball 3220 extends into the interior of the through hole 3219. A second spring 3221 is fixedly connected to the other end of the sealing ball 3220.

[0038] By starting the drive motor 312, the gear 313 can be driven to rotate. During this process, the gear 313 drives the gear ring 317 to rotate the connecting ring 314, thereby driving the scraper 316 and the connecting shaft 315 to rotate synchronously. During this process, the edge of the scraper 316 can scrape and clean the concentrated liquid adhering to the inner wall of the feed pipe 304, reducing adhesion. During the rotation and scraping process, the suction structure 32 can guide this part of the concentrated liquid into the interior of the spray drying tower 1, thereby increasing the yield of the finished product and avoiding the situation where the concentrated liquid adheres to the inner wall of the pipe during the traditional process of introducing the concentrated liquid, reducing the yield of the finished product.

[0039] like Figure 1-13 As shown, the suction structure 32 includes a first mounting ring 321 fixedly connected to the inner wall of the guide tube 304. The first mounting ring 321 has a communicating cavity 327 inside. A slip ring 326 is rotatably connected to the inner side of the first mounting ring 321. The inner side of the slip ring 326 is fixedly connected to the lower end of the surface of the scraper 316. The surface of the slip ring 326 has evenly distributed outlet holes 325 that communicate with the first mounting ring 321. The suction structure 32 also includes a guide groove 323 opened inside the scraper 316. The surface of plate 316 has evenly distributed inlet ports 324 that communicate with guide grooves 323. The bottom of scraper 316 has mounting holes 328 that communicate with guide grooves 323. The mounting holes 328 communicate with adjacent outlet holes 325. Two second mounting rings 3212 are fixedly connected to the inner wall of the mounting holes 328. A connecting post 329 is fixedly connected to the inner side of the second mounting rings 3212. A sealing ring 3211 is slidably connected to the surface of the connecting post 329. The bottom of the sealing ring 3211... A first spring 3213 is fixedly connected to the surface of the second mounting ring 3212. The surface of the connecting post 329 has evenly distributed through grooves 3210. The suction structure 32 also includes a second mounting shell 3214 fixedly connected to the surface of the guide tube 304. A partition 3215 is fixedly connected to the inner wall of the second mounting shell 3214. Evenly distributed connecting holes are formed on the upper surface of the partition 3215. A collection cavity is formed between one side of the partition 3215 and the inner wall of the second mounting shell 3214. An adjustment cavity is formed between the other side of plate 3215 and the inner wall of the second mounting shell 3214. A connecting pipe 322 communicating with the collection cavity is provided on the surface of the second mounting shell 3214. The other end of the connecting pipe 322 is connected with the connecting cavity 327. A second air pump 3217 and a second air pump 3217 are arranged sequentially from top to bottom on the side of the second mounting shell 3214 away from the guide pipe 304. An installation pipe communicating with the adjustment cavity is provided on the side of the first air pump 3216 and the second air pump 3217.

[0040] By activating the first air pump 3216, air inside the regulating chamber can be discharged through the connected mounting pipe, and air inside the collecting chamber can be discharged through the connecting hole, creating a negative pressure inside. During this process, air inside the connecting chamber 327 can be discharged along with the connecting pipe 322, thereby creating a negative pressure inside the guide groove 323 through the outlet hole 325 and the mounting hole 328. Under the action of the inlet 324, the scraped adhesive concentrate is introduced into the guide groove 323. It is then introduced into the collecting chamber for storage through the guide groove 323, the mounting hole 328, the outlet hole 325, the connecting chamber 327, and the connecting pipe 322. During this process, the sealing ring 3211 at the bottom inside the mounting hole 328 can block the lower opening of the mounting hole 328 with the connecting post 329. The sealing ring 3211 at the top inside the mounting hole 328 can squeeze the first spring 3213 under the airflow and expose the upper through groove 3210, allowing the concentrate to be discharged through the gap between the inner side of the sealing ring 3211 and the through groove 3210.

[0041] After collection is completed, the first air pump 3216 is turned off and the second air pump 3217 is started to introduce air into the regulating chamber and the collecting chamber. During this process, the collected concentrate is pushed through the connecting pipe 322, the connecting chamber 327 and the outlet hole 325 and introduced into the mounting hole 328. During this process, under the pressure of the concentrate and the introduced gas, the sealing ring 3211 inside the mounting hole 328 cooperates with the connecting column 329 to block the upper opening of the mounting hole 328, preventing the concentrate from being discharged through the guide groove 323 and the inlet 324. At the same time, the concentrate is introduced into the interior of the spray drying tower 1 through the feed pipe 304 through the lower opening of the mounting hole 328, thereby reducing the situation of concentrate adhering to the inner wall of the traditional pipeline and reducing the yield of finished product, effectively increasing the yield of finished product and improving the utilization rate of concentrate.

[0042] The connecting pipe 3218 is designed so that when too much air is discharged from the inside of the feed pipe 304 during the absorption of concentrated liquid, the outside air can push the sealing ball 3220 and squeeze the second spring 3221 to contract into the inside of the connecting pipe 3218, so that the outside air can be introduced into the inside of the feed pipe 304, avoiding the situation where the pressure inside the feed pipe 304 is too low and causes deformation.

[0043] like Figure 1-13As shown, the auxiliary structure 4 includes a connecting shell 401 disposed on one side of the spray drying tower 1. One side of the connecting shell 401 is connected to the discharge pipe, and a discharge cavity is formed on the surface of the connecting shell 401. A removable cover plate 404 is provided on the surface of the connecting shell 401 to cover the discharge cavity. A staggered heat-conducting shell 409 is fixedly connected inside the connecting shell 401. A heat exchange tube 410 is provided inside the heat-conducting shell 409. A rotating shaft 405 is rotatably connected to the inner wall of the connecting shell 401. A uniformly distributed drive blade 406 is fixedly connected to the surface of the rotating shaft 405. The other end of the rotating shaft 405 passes through the connecting shell 401 and is provided with a transmission mechanism 408 (the transmission mechanism 408 is a relatively mature component in existing technology applications, consisting of two drive wheels and a drive belt. By driving one drive wheel to rotate, the other drive wheel can be driven to rotate under the action of the drive belt). The other end of the transmission mechanism 408 is fixed. A reciprocating screw 407 is connected, and the other end of the reciprocating screw 407 passes through the connecting shell 401 and is rotatably connected to the inner wall of the connecting shell 401. (The reciprocating screw 407 is a reciprocating screw 407 that can make the slider reciprocate without changing the rotation direction of the main shaft. The reciprocating screw 407 is in the form of two threaded grooves with the same pitch and opposite rotation direction, and the two ends are connected by a transition curve. By rotating the reciprocating screw 407, the side of the helical groove pushes the slider placed in the helical groove to make axial reciprocating motion.) The connecting shell 401 is slidably connected to a connecting plate 402. Two sliders are fixedly connected to the upper end of the connecting plate 402. One slider is set on the surface of the reciprocating screw 407. The bottom of the connecting plate 402 is fixedly connected to a uniformly distributed sliding plate 403. The opposite sides of two adjacent sliding plates 403 are fixedly connected to uniformly distributed bristles. The other end of the bristles is in contact with the surface of the heat-conducting shell 409.

[0044] After the concentrated liquid is dried by the combined action of the spray drying tower 1 and the blower 2, it is discharged along with the exhaust airflow through the discharge pipe. During this process, the exhaust airflow and the finished product can be introduced into the interior of the connecting shell 401. The airflow introduced into the connecting shell 401 drives the drive blade 406 to rotate, thereby driving the rotating shaft 405 to rotate. Under the action of the transmission mechanism 408, the reciprocating screw 407 is driven to rotate. During this process, the connecting plate 402 can be moved back and forth by the slider, thereby driving the bristles on the sliding plate 403 to clean the surface of the heat-conducting shell 409. This allows the finished product adhering to the surface of the heat-conducting shell 409 to fall to the inner bottom wall of the connecting shell 401, so that the staff can take out the finished product by opening the cover plate 404.

[0045] By setting up the heat-conducting shell 409, the airflow can be slowed down. At the same time, by introducing a heat exchange medium into the heat exchange tube 410, the waste heat of the airflow can be collected. In conjunction with the waste heat utilization equipment, the heat energy can be converted into other forms of energy for use by other equipment. The waste heat absorbed by the heat exchange tube 410 can also be used to preheat the gas introduced by the blower 2. The specific choice should be made according to the actual situation. The waste heat is effectively utilized to reduce production costs. After heat exchange, the airflow and the remaining finished products can be separated by a cyclone separator. The cyclone separator is an auxiliary equipment in the spray drying production and is therefore not shown in the figure.

[0046] In use, the concentrated liquid is stored in the storage tank 301 through the feed pipe 303. After preheating by starting the blower 2 and the spray drying tower 1, the pump 302 is started to introduce the concentrated liquid in the storage tank 301 into the spray drying tower 1 for spray drying. The dried product and airflow are discharged through the discharge pipe. The discharged airflow and finished product can be introduced into the connecting shell 401. The airflow introduced into the connecting shell 401 drives the drive blade 406 to rotate. The heat-conducting shell 409 can slow down the airflow. At the same time, a heat exchange medium is introduced into the heat exchange tube 410. It can be used to collect the waste heat of the airflow and, together with the waste heat utilization equipment, convert the heat energy into other forms of energy for use by other equipment. In this process, some finished products can be blocked by the heat-conducting shell 409. With the cooperation of the drive blade 406, the rotating shaft 405 and the transmission mechanism 408, the reciprocating screw 407 can be driven to rotate, thereby driving the bristles on the sliding plate 403 to clean the surface of the heat-conducting shell 409, so that the finished products adhering to the surface of the heat-conducting shell 409 can fall to the inner bottom wall of the connecting shell 401, so that the subsequent staff can take out the finished products by opening the cover plate 404.

[0047] After the concentrate is discharged from the storage tank 301, some concentrate will adhere to the inside of the feed pipe 304. Starting the drive motor 312 will rotate the gear 313, which in turn will drive the gear ring 317 to rotate the connecting ring 314. This will drive the scraper 316 and the connecting shaft 315 to rotate synchronously. During this process, the edge of the scraper 316 can scrape and clean the concentrate adhering to the inner wall of the feed pipe 304, reducing adhesion. During the rotational scraping process, the suction structure 32 can guide this portion of concentrate into the spray drying tower 1, thereby increasing the yield and avoiding the problems associated with traditional concentrate introduction methods. In cases where the concentrate adheres to the inner wall of the pipe, reducing the yield of the finished product, the first air pump 3216 can be activated to guide the scraped concentrate into the collection chamber for storage. After collection, the first air pump 3216 is turned off and the second air pump 3217 is activated to introduce air into the regulating chamber and the collection chamber. During this process, the collected concentrate is pushed through the connecting pipe 322, the connecting chamber 327 and the outlet hole 325 and introduced into the mounting hole 328. At the same time, the concentrate is introduced into the spray drying tower 1 through the feed pipe 304 through the lower opening of the mounting hole 328. This reduces the situation where the concentrate adheres to the inner wall of the traditional pipe, reducing the yield of the finished product, and effectively increases the yield of the finished product and the utilization rate of the concentrate.

[0048] It should be noted that the spray drying tower 1, blower 2, pump body 302, drive motor 312, first air pump 3216 and second air pump 3217 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the spray drying tower 1, blower 2, pump body 302, drive motor 312, first air pump 3216 and second air pump 3217 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
