Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical intermediate production and preparation, and specifically provides a device for producing and preparing pharmaceutical intermediates. Background Art

[0002] Pharmaceutical intermediates refer to compounds generated during the drug synthesis process. They are usually precursors or intermediate products of drugs and are ultimately converted into the final required drugs through a series of chemical reactions.

[0003] The patent with the patent publication number CN216245429U relates to a device body for producing and preparing pharmaceutical intermediates, including a bin body, and also including a centrifugal fan and a cyclone separator. The output end of the centrifugal fan is fixedly installed with a number of intake pipes with one end extending into the bin body. The top of the bin body is communicated with the cyclone separator through a first connecting pipe. A feeding mechanism is fixedly installed on the right side of the bin body. The input end of the centrifugal fan is communicated with a pretreatment mechanism. The top of the cyclone separator is communicated with the top of the pretreatment mechanism through a second connecting pipe. This device body for producing and preparing pharmaceutical intermediates solves the problems that the traditional device body for producing and preparing pharmaceutical intermediates does not have a waste heat recovery function when in use, wastes waste heat resources relatively seriously, and since the material is wet, it is easy to have a stacking phenomenon during the feeding process, affecting the drying efficiency and having poor practicability.

[0004] In the above patent, it solves the problems that the traditional device body for producing and preparing pharmaceutical intermediates does not have a waste heat recovery function when in use, wastes waste heat resources relatively seriously, and since the material is wet, it is easy to have a stacking phenomenon during the feeding process, affecting the drying efficiency. However, when drying pharmaceutical intermediates, the humidity inside the device body will gradually increase. When the humidity is too high, the condensed water generated will drip back onto the pharmaceutical intermediates again, thus affecting the drying of the pharmaceutical intermediates.

[0005] Therefore, it is very necessary to design a device for producing and preparing pharmaceutical intermediates that can avoid the water remaining inside the collection frame from affecting the humidity inside the device body. Summary of the Invention

[0006] The purpose of the present invention is to provide a device for producing and preparing pharmaceutical intermediates to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the present invention provides the following technical solutions: A device for producing and preparing a pharmaceutical intermediate, including a device body, further including a drainage device and a dispersion device. Among them, a support plate is fixedly installed on the top of the device body, a motor is fixedly installed on the top of the device body, a rotating shaft is rotatably installed inside the support plate, and the output end of the motor is fixed to the rotating shaft. Among them, the drainage device includes a drying plate and a collection component. The drying plate is slidably sleeved on the surface of the rotating shaft. The collection component includes a pushing plate, a collection box, a jetting box, a sealing plate, a bending rod, an arc plate, and a condensation rod. The pushing plate is slidably installed on the surface of the rotating shaft. The collection box is fixedly installed inside the device body. The jetting box fixedly penetrates the collection box. The sealing plate is slidably installed inside the jetting box. The bending rod is fixedly installed on the surface of the sealing plate. The arc plate is fixedly installed on the surface of the bending rod. The condensation rod is fixedly installed on the top of the inner wall of the device body. Among them, the dispersion device includes a pushing plate and a filtering component. A heating device is arranged inside the drying plate. When the bending rod moves, it will drive the sealing plate to move. When the sealing plate moves, it will squeeze the inside of the jetting box, so that the gas inside the jetting box will be ejected from the jetting box, avoiding the water remaining inside the collection box from affecting the humidity inside the device body. At the same time, the condensation rod can prevent the generated condensed water from dropping on the pharmaceutical intermediate.

[0008] According to the above technical solution, a first spring is arranged between the drying plate and the rotating shaft, a second spring is arranged between the sealing plate and the jetting box, and a drainage port is fixedly installed on the surface of the collection box. The first spring can support the drying plate.

[0009] According to the above technical solution, the pushing plate is fixedly installed on the surface of the pushing board. The filtering component includes an elastic plate, a sleeve block, a connecting rod, and a pressing rod. The elastic plate is fixedly installed on the surface of the pushing plate. The sleeve block is sleeved on the surface of the rotating shaft. The connecting rod is fixedly installed on the surface of the sleeve block. The pressing rod is fixedly installed at the bottom of the connecting rod. The pressing rod will push the elastic plate and the pushing plate to deform. When the elastic plate and the pressing rod push the material, the elastic plate and the pushing plate will reset under the action of their own elastic force, and the pharmaceutical intermediate will be more dispersed to improve the drying effect.

[0010] According to the above technical solution, an annular filter plate is fixedly installed on the top of the drying plate. The connecting rod is fixed to the annular filter plate. The edge of the drying plate is a grid plate. Through the grid plate, the pharmaceutical intermediate can be discharged from the edge of the drying plate.

[0011] According to the above technical solution, it further includes a feeding device and a discharging device. The discharging device includes an impact block and a vibration assembly. The feeding device is arranged on the top of the device body. The feeding device includes a feeding plate and a material control assembly. The feeding plate is fixedly installed on the top of the device body. The feeding device includes a stress rubber, an expansion rubber, a diversion plate, a baffle, a contact plate and a triangular block. The stress rubber and the expansion rubber are both fixedly installed on the surface of the rotating shaft. The diversion plate is fixedly installed on the surface of the feeding plate. The baffle is slidably installed on the left side of the diversion plate. The contact plate is slidably installed inside the feeding plate. The triangular block is fixedly installed on the left side of the baffle. The stress rubber is communicated with the expansion rubber through a pipeline. When the contact plate moves, it will contact the inclined surface of the triangular block. When the contact plate moves on the inclined surface of the triangular block, it will push the triangular block and the baffle to move. When the baffle moves, it will block the left side of the diversion plate, avoiding the influence on the device body when too much pharmaceutical intermediate enters the device body continuously when there is too much pharmaceutical intermediate on the drying plate.

[0012] According to the above technical solution, a third spring is arranged between the baffle and the diversion plate. The triangular block contacts the contact plate, and the third spring can drive the baffle to reset.

[0013] According to the above technical solution, the impact block slidably penetrates the bottom of the device body. The vibration assembly includes a fixed rod. The fixed rod is fixedly installed on the surface of the rotating shaft. A fourth elastic sheet is arranged between the impact block and the device body. The bottom of the fixed rod is arc-shaped. When the fixed rod rotates, the bottom of the fixed rod will contact the impact block, so that the arc-shaped position at the bottom of the fixed rod will push the impact block to move downward. When the impact block moves downward, it will impact the bottom of the device body, causing the bottom of the device body to vibrate, avoiding the pharmaceutical intermediate remaining at the bottom of the device body and unable to be discharged.

[0014] According to the above technical solution, a storage box is fixedly installed on the surface of the device body. A heat conduction plate is fixedly installed at the bottom of the feeding plate. A piston plate is slidably installed inside the storage box. The piston plate is fixed to the impact block through a transmission rod. The storage box is communicated with the inside of the heat conduction plate through a heat preservation pipe. The water discharged from the drain port will enter the inside of the storage box. When the impact block moves, it will drive the transmission rod and the piston plate to move. When the piston plate moves, it will push the high-temperature gas inside the storage box into the inside of the heat conduction plate. The heat conduction plate can preheat the pharmaceutical intermediate on the feeding plate, thereby reducing the heat loss inside the device body.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) For the production and preparation device of this pharmaceutical intermediate, the water vapor inside the device body can be condensed by the condensation rod, and the generated condensed water will drip into the inside of the collection frame for collection. When the rotating shaft drives the pushing plate to rotate, it will contact the arc plate and the bending rod. The pushing plate will push the bending rod and the sealing plate to move, and the sealing plate will squeeze the gas inside the jet frame to eject. The gas ejected from the jet frame will blow the water inside the collection frame towards the drainage port, preventing the water remaining inside the collection frame from affecting the humidity inside the device body. At the same time, the condensation rod can prevent the generated condensed water from dripping onto the pharmaceutical intermediate.

[0016] (2) For the production and preparation device of this pharmaceutical intermediate, when the pushing plate rotates, it will drive the pushing plate and the elastic plate to rotate. The pharmaceutical intermediate can be filtered through the pushing plate, making the pharmaceutical intermediate more dispersed and improving the drying effect. When the elastic plate contacts the extrusion rod, it will push the pushing plate to deform. After the elastic rod disengages from the extrusion rod, the pushing plate will quickly reset and push the pharmaceutical intermediate on the drying plate, thereby improving the drying efficiency of the pharmaceutical intermediate.

[0017] (3) For the production and preparation device of this pharmaceutical intermediate, when there is too much pharmaceutical intermediate on the drying plate, the gravity of the pharmaceutical intermediate will push the drying plate downward, causing the drying plate to squeeze the stress rubber. The air inside the stress rubber will enter the inside of the expansion rubber and squeeze the expansion rubber to generate expansion. The expansion of the expansion rubber will push the contact plate to move, and the contact plate will push the baffle to move through the triangular block to block the feeding plate, preventing more pharmaceutical intermediate from entering the device body and affecting the device body.

[0018] (4) For the production and preparation device of this pharmaceutical intermediate, when the rotating shaft rotates, it will drive the fixed rod to rotate. The fixed rod will push the impact block to move. When the impact block moves downward, it will impact the bottom of the device body, causing the bottom of the device body to vibrate, preventing the pharmaceutical intermediate from remaining at the bottom of the device body and unable to be discharged. At the same time, the storage frame will collect the discharged water. The impact block will push the sealing plate upward, and the piston plate will push the high-temperature air inside the storage frame into the inside of the heat conduction plate. The heat conduction plate can preheat the pharmaceutical intermediate on the feeding plate, thereby reducing the heat loss inside the device body. Description of the Drawings

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0022] Please refer to Figures 1-5, the present invention provides a technical solution: a device for producing and preparing a pharmaceutical intermediate, including a device body 1, and further including a drainage device and a dispersion device. Among them, a support plate 2 is fixedly installed on the top of the device body 1, and a motor is fixedly installed on the top of the device body 1. A rotating shaft 3 is rotatably installed inside the support plate 2, and the output end of the motor is fixed to the rotating shaft 3. Among them, the drainage device includes a drying plate 42 and a collection assembly. The drying plate 42 is slidably sleeved on the surface of the rotating shaft 3. The collection assembly includes a push plate 41, a collection frame 43, a jet frame 44, a sealing plate 45, a bent rod 46, an arc plate 47, and a condensation rod 49. The push plate 41 is slidably installed on the surface of the rotating shaft 3. The collection frame 43 is fixedly installed inside the device body 1. The jet frame 44 is fixedly penetrated through the collection frame 43. The sealing plate 45 is slidably installed inside the jet frame 44. The bent rod 46 is fixedly installed on the surface of the sealing plate 45. The arc plate 47 is fixedly installed on the surface of the bent rod 46. The condensation rod 49 is fixedly installed on the top of the inner wall of the device body 1. Among them, the dispersion device includes a pushing plate 61 and a filtering assembly. A heating device is provided inside the drying plate 42. When the push plate 41 rotates, it will contact the arc plate 47 and the bent rod 46, so that the push plate 41 will push the arc plate 47 and the bent rod 46 to move. When the bent rod 46 moves, it will drive the sealing plate 45 to move. When the sealing plate 45 moves, it will squeeze the inside of the jet frame 44, so that the gas inside the jet frame 44 will be ejected from the jet frame 44, avoiding the water remaining inside the collection frame 43 from affecting the humidity inside the device body 1. At the same time, the condensation rod 49 can prevent the generated condensed water from dripping on the pharmaceutical intermediate.

[0023] A first spring is provided between the drying plate 42 and the rotating shaft 3, and a second spring is provided between the sealing plate 45 and the jet frame 44. A drain port 48 is fixedly installed on the surface of the collection frame 43. The first spring can support the drying plate 42.

[0024] The pushing plate 61 is fixedly installed on the surface of the push plate 41. The filtering assembly includes an elastic plate 62, a sleeve block 63, a connecting rod 64, and an extrusion rod 65. The elastic plate 62 is fixedly installed on the surface of the pushing plate 61. The sleeve block 63 is sleeved on the surface of the rotating shaft 3. The connecting rod 64 is fixedly installed on the surface of the sleeve block 63. The extrusion rod 65 is fixedly installed at the bottom of the connecting rod 64. The pushing plate 61 and the annular filter plate can filter the pharmaceutical intermediate. At the same time, when the elastic plate 62 contacts the extrusion rod 65, the extrusion rod 65 will push the elastic plate 62 and the pushing plate 61 to deform. When the elastic plate 62 and the extrusion rod 65 push the material, the elastic plate 62 and the pushing plate 61 will return to their original positions under the action of their own elastic force, and the pharmaceutical intermediate will be more dispersed to improve the drying effect.

[0025] At the top of the drying plate 42, an annular filter plate is fixedly installed. The connecting rod 64 is fixed to the annular filter plate. The edge of the drying plate 42 is provided as a grid plate, through which the pharmaceutical intermediate can be discharged from the edge of the drying plate 42.

[0026] During the operation of the first embodiment, the pharmaceutical intermediate on the drying plate 42 can be dried through the drying plate 42. The motor can drive the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it will drive the pushing plate 41 to rotate. When drying the pharmaceutical intermediate, the humidity inside the device body 1 will increase, causing water vapor to condense on the condensing rod 49. The water on the surface of the condensing rod 49 will drip into the inside of the collection frame 43. When the pushing plate 41 rotates, it will contact the arc plate 47 and the bending rod 46, causing the pushing plate 41 to push the arc plate 47 and the bending rod 46 to move. When the bending rod 46 moves, it will drive the sealing plate 45 to move. When the sealing plate 45 moves, it will squeeze the inside of the air jet frame 44, causing the gas inside the air jet frame 44 to be ejected from the air jet frame 44. The gas ejected from the air jet frame 44 will blow the water inside the collection frame 43 towards the drainage port 48, and at the same time, the water will be discharged from the drainage port 48. When the rotating shaft 3 rotates to drive the pushing plate 41 to rotate, the pushing plate 41 will drive the pushing plate 61 and the elastic plate 62 to rotate. When the pushing plate 41 and the pushing plate 61 rotate, they can push the pharmaceutical intermediate on the drying plate 42 to move, causing the pharmaceutical intermediate to move towards the edge of the drying plate 42 under the action of centrifugal force. The pharmaceutical intermediate can be filtered through the pushing plate 61 and the annular filter plate. At the same time, when the elastic plate 62 contacts the extrusion rod 65, the extrusion rod 65 will push the elastic plate 62 and the pushing plate 61 to deform. When the elastic plate 62 and the extrusion rod 65 push the material, the elastic plate 62 and the pushing plate 61 will return to their original positions under the action of their own elastic force, causing the pushing plate 61 to push the pharmaceutical intermediate to move.

When the contact plate 56 moves on the inclined surface of the triangular block 57, it will push the triangular block 57 and the baffle 55 to move. When the baffle 55 moves, it will block the left side of the diversion plate 54, preventing excessive pharmaceutical intermediates on the drying plate 42 from continuing to enter the inside of the device body 1 and affecting the device body 1.

[0028] A third spring is provided between the baffle 55 and the diversion plate 54. The triangular block 57 contacts the contact plate 56, and the third spring can drive the baffle 55 to reset.

The bottom of the fixed rod 72 is arc-shaped. When the fixed rod 72 rotates, the bottom of the fixed rod 72 will contact the impact block 71, causing the arc-shaped position at the bottom of the fixed rod 72 to push the impact block 71 downward. When the impact block 71 moves downward, it will impact the bottom of the device body 1, causing the bottom of the device body 1 to vibrate, preventing pharmaceutical intermediates from remaining at the bottom of the device body 1 and being unable to be discharged.

[0030] A storage frame 73 is fixedly installed on the surface of the device body 1. A heat conduction plate 76 is fixedly installed at the bottom of the feeding plate 51.

When the piston plate 75 moves, it will push the high-temperature gas inside the storage frame 73 into the inside of the heat conduction plate 76. The heat conduction plate 76 can preheat the pharmaceutical intermediates on the feeding plate 51, thereby reducing the heat loss inside the device body 1.

[0031] When there is too much pharmaceutical intermediate on the drying plate 42 during the operation of the second embodiment, the gravity of the pharmaceutical intermediate will press the drying plate 42 to move downward. When the drying plate 42 moves downward, it will squeeze the stress rubber 52, so that the gas inside the stress rubber 52 will enter the inside of the expansion rubber 53 through the pipeline. The increase in the gas inside the expansion rubber 53 will cause expansion. When the expansion rubber 53 expands, it will push the contact plate 56 to move. When the contact plate 56 moves, it will contact the inclined surface of the triangular block 57. When the contact plate 56 moves on the inclined surface of the triangular block 57, it will push the triangular block 57 and the baffle 55 to move. When the baffle 55 moves, it will block the left side of the diversion plate 54 to prevent the pharmaceutical intermediate inside the feed plate 51 from continuing to enter the inside of the device body 1; When the rotating shaft 3 rotates, it will drive the fixed rod 72 to rotate. When the fixed rod 72 rotates, the bottom of the fixed rod 72 will contact the impact block 71, so that the arc position at the bottom of the fixed rod 72 will push the impact block 71 to move downward. When the impact block 71 moves downward, it will impact the bottom of the device body 1 to cause the bottom of the device body 1 to vibrate. When the impact block 71 moves, it will drive the transmission rod 74 and the piston plate 75 to move. When the piston plate 75 moves, it will push the high-temperature gas inside the storage frame 73 into the inside of the heat conduction plate 76. Through the heat conduction plate 76, the bottom of the feed plate 51 and the pharmaceutical intermediate can be heated.
